It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

[...] when looping through the Iterable value list, each Object instance is re-used, so it only keeps one instance around at a given time.

My situation is different: I was trying to seed the database with 30 users, belonging to specific roles, so I was running this code:

for (var i = 1; i <= 30; i++)
{
    CreateUserWithRole("Analyst", $"analyst{i}", UserManager);
}

This was a Sync function. Inside of it I had 3 calls to:

UserManager.FindByNameAsync(username).Result
UserManager.CreateAsync(user, pass).Result
UserManager.AddToRoleAsync(user, roleName).Result

When I replaced .Result with .GetAwaiter().GetResult(), this error went away.

Try setting mapper.configure(DeserializationConfig.Feature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT, true)

or

mapper.enable(DeserializationFeature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT);

depending on your Jackson version.

I made a method to do this below called jsonArrayToObjectList. Its a handy static class that will take a filename and the file contains an array in JSON form.

 List<Items> items = jsonArrayToObjectList(
            "domain/ItemsArray.json",  Item.class);

    public static <T> List<T> jsonArrayToObjectList(String jsonFileName, Class<T> tClass) throws IOException {
        ObjectMapper mapper = new ObjectMapper();
        final File file = ResourceUtils.getFile("classpath:" + jsonFileName);
        CollectionType listType = mapper.getTypeFactory()
            .constructCollectionType(ArrayList.class, tClass);
        List<T> ts = mapper.readValue(file, listType);
        return ts;
    }

Here is the approach I follow whenever I see this type of error:

1. One way to debug this issue is by first taking whatever response is coming as String.class then applying Gson().fromJson(StringResp.body(), MyDTO.class). It will still fail most probably but this time it will throw the fields which are creating this error to happen in first place. Post the modification, we can use the previous approach as usual.

ResponseEntity<String> respStr = restTemplate.exchange(URL,HttpMethod.GET, entity, String.class);
Gson g = new Gson();

The below step will throw error with the fields which is causing the issue

MyDTO resp = g.fromJson(respStr.getBody(), MyDTO.class);

I don't have the error message with me but it will point to the field which is problematic and the reason for it. Resolve those and try again with previous approach.

I guess you are using an old version of hibernate. You can download the latest version, 5.2, from here.

i am using my custom implementation in kotlin:

/**

object JsonParser {

    val TAG = "JsonParser"
    /**

    @Throws(JSONException::class)
    fun parseJson(objJson: Any?, map :HashMap<String, String>, include : Array<String>?): Map<String, String> {
        // If obj is a json array
        if (objJson is JSONArray) {
            for (i in 0 until objJson.length()) {
                parseJson(objJson[i], map, include)
            }
        } else if (objJson is JSONObject) {
            val it: Iterator<*> = objJson.keys()
            while (it.hasNext()) {
                val key = it.next().toString()

                        )

                        )
                    }
                    else -> {
//
                        if(include == null || include.contains(key)) // here is check for include param
                        {
                            map[key] = jobject.toString()
                            Log.e(TAG, " adding to map: $key $jobject")
                        }
                    }
                }
            }
        }
        return map
    }

    /**

    fun parseJson(objJson: Any?, map :HashMap<String, String>): Map<String, String> {

You can use it like:

    val include= arrayOf(
        "atHome",//JSONArray
        "cat",
        "dog",
        "persons",//JSONArray
        "man",
        "woman"
    )
    JsonParser.parseJson(jsonObject, map, include)
    val linearContent: LinearLayout = taskInfoFragmentBinding.infoContainer

here is some useful links:

json parsing :

plugin: https://plugins.jetbrains.com/plugin/9960-json-to-kotlin-class-jsontokotlinclass-

create POJOs from json: https://codebeautify.org/jsonviewer

Retrofit: https://square.github.io/retrofit/

Gson: https://github.com/google/gson

This worked for me:

 @JsonFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSZ", shape = JsonFormat.Shape.STRING)
 private LocalDateTime startDate;

For ASP.NET Core (tested using 2.0+ and 3.0), if you prefer to read the source documentation: https://github.com/AutoMapper/AutoMapper.Extensions.Microsoft.DependencyInjection/blob/master/README.md

Otherwise following these 4 steps works:

1. Install AutoMapper.Extensions.Microsoft.DependancyInjection from nuget.

2. Simply add some profile classes.

3. Then add below to your startup.cs class. services.AddAutoMapper(OneOfYourProfileClassNamesHere)

4. Then simply Inject IMapper in your controllers or wherever you need it:

public class EmployeesController {

    private readonly IMapper _mapper;

    public EmployeesController(IMapper mapper){

        _mapper = mapper;
    }

And if you want to use ProjectTo its now simply:

var customers = await dbContext.Customers.ProjectTo<CustomerDto>(_mapper.ConfigurationProvider).ToListAsync()

You're almost here, you're just missing a few things:

PUT /test
{
  "mappings": {
    "type_name": {                <--- add the type name
      "properties": {             <--- enclose all field definitions in "properties"
        "field1": {
          "type": "integer"
        },
        "field2": {
          "type": "integer"
        },
        "field3": {
          "type": "string",
          "index": "not_analyzed"
        },
        "field4,": {
          "type": "string",
          "analyzer": "autocomplete",
          "search_analyzer": "standard"
        }
      }
    }
  },
  "settings": {
     ...
  }
}

UPDATE

If your index already exists, you can also modify your mappings like this:

PUT test/_mapping/type_name
{
    "properties": {             <--- enclose all field definitions in "properties"
        "field1": {
          "type": "integer"
        },
        "field2": {
          "type": "integer"
        },
        "field3": {
          "type": "string",
          "index": "not_analyzed"
        },
        "field4,": {
          "type": "string",
          "analyzer": "autocomplete",
          "search_analyzer": "standard"
        }
    }
}

UPDATE:

As of ES 7, mapping types have been removed. You can read more details here

add plt.figure(figsize=(16,5)) before the sns.heatmap and play around with the figsize numbers till you get the desired size

...

plt.figure(figsize = (16,5))

ax = sns.heatmap(df1.iloc[:, 1:6:], annot=True, linewidths=.5)

Array.prototype.map() index:

One can access the index Array.prototype.map() via the second argument of the callback function. Here is an example:

const array = [1, 2, 3, 4];_x000D_
_x000D_
_x000D_
const map = array.map((x, index) => {_x000D_
  console.log(index);_x000D_
  return x + index;_x000D_
});_x000D_
_x000D_
console.log(map);

Other arguments of Array.prototype.map():

• The third argument of the callback function exposes the array on which map was called upon
• The second argument of Array.map() is a object which will be the this value for the callback function. Keep in mind that you have to use the regular function keyword in order to declare the callback since an arrow function doesn't have its own binding to the this keyword.

For example:

const array = [1, 2, 3, 4];_x000D_
_x000D_
const thisObj = {prop1: 1}_x000D_
_x000D_
_x000D_
const map = array.map( function (x, index, array) {_x000D_
  console.log(array);_x000D_
  console.log(this)_x000D_
}, thisObj);

I came upon a similar issue recently and following Fabian's advice actually led me to the solution. Turns out with client certs you have to ensure two things:

1. The private key is actually being exported as part of the cert.

2. The application pool identity running the app has access to said private key.

In our case I had to:

1. Import the pfx file into the local server store while checking the export checkbox to ensure the private key was sent out.
2. Using MMC console, grant the service account used access to the private key for the cert.

The trusted root issue explained in other answers is a valid one, it was just not the issue in our case.

How about adding this to your pom.xml

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
    <version>${jackson.version}</version>
</dependency>

Considering @Arpit answer, for me it worked only when I add two jackson dependencies:

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>2.4.3</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.4.3</version>
</dependency>

and configured, of cause, web.xml <mvc:annotation-driven/>.

Original answer that helped me is here: https://stackoverflow.com/a/33896080/3014866

I think you can just cast to ObjectNode and use put method. Like this

ObjectNode o = (ObjectNode) jsonNode; o.put("value", "NO");

mAddTaskButton is null because you never initialize it with:

mAddTaskButton = (Button) findViewById(R.id.addTaskButton);

before you call mAddTaskButton.setOnClickListener().

If using the fasterxml then,

these changes might be needed

import com.fasterxml.jackson.core.JsonParser;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.core.Version;
import com.fasterxml.jackson.databind.DeserializationContext;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.deser.std.StdDeserializer;
import com.fasterxml.jackson.databind.module.SimpleModule;
import com.fasterxml.jackson.databind.node.ObjectNode;

in main method--

use

SimpleModule module =
  new SimpleModule("PolymorphicAnimalDeserializerModule");

instead of

new SimpleModule("PolymorphicAnimalDeserializerModule",
      new Version(1, 0, 0, null));

and in Animal deserialize() function, make below changes

//Iterator<Entry<String, JsonNode>> elementsIterator =  root.getFields();
Iterator<Entry<String, JsonNode>> elementsIterator = root.fields();

//return mapper.readValue(root, animalClass);
return  mapper.convertValue(root, animalClass); 

This works for fasterxml.jackson. If it still complains of the class fields. Use the same format as in the json for the field names (with "_" -underscore). as this
//mapper.setPropertyNamingStrategy(new CamelCaseNamingStrategy()); might not be supported.

abstract class Animal
{
  public String name;
}

class Dog extends Animal
{
  public String breed;
  public String leash_color;
}

class Cat extends Animal
{
  public String favorite_toy;
}

class Bird extends Animal
{
  public String wing_span;
  public String preferred_food;
}

I am answering bit late to this question, but someone, in future, might find this useful. The below approach, besides lots of other approaches, works best, and I personally think would better suit a web application.

@Configuration
@EnableWebMvc
public class WebConfiguration extends WebMvcConfigurerAdapter {

 ... other configurations

@Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        Jackson2ObjectMapperBuilder builder = new Jackson2ObjectMapperBuilder();
        builder.serializationInclusion(JsonInclude.Include.NON_NULL);
        builder.propertyNamingStrategy(PropertyNamingStrategy.CAMEL_CASE_TO_LOWER_CASE_WITH_UNDERSCORES);
        builder.serializationInclusion(Include.NON_EMPTY);
        builder.indentOutput(true).dateFormat(new SimpleDateFormat("yyyy-MM-dd"));
        converters.add(new MappingJackson2HttpMessageConverter(builder.build()));
        converters.add(new MappingJackson2XmlHttpMessageConverter(builder.createXmlMapper(true).build()));
    }
}

If you consider using fastjson, you can solve your problem, note the version

 <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>fastjson</artifactId>
        <version>1.2.56</version>
 </dependency>

The error is:

Can not deserialize instance of java.lang.String out of START_ARRAY token at [Source: line: 1, column: 1095] (through reference chain: JsonGen["platforms"])

In JSON, platforms look like this:

"platforms": [
    {
        "platform": "iphone"
    },
    {
        "platform": "ipad"
    },
    {
        "platform": "android_phone"
    },
    {
        "platform": "android_tablet"
    }
]

So try change your pojo to something like this:

private List platforms;

public List getPlatforms(){
    return this.platforms;
}

public void setPlatforms(List platforms){
    this.platforms = platforms;
}

EDIT: you will need change mobile_networks too. Will look like this:

private List mobile_networks;

public List getMobile_networks() {
    return mobile_networks;
}

public void setMobile_networks(List mobile_networks) {
    this.mobile_networks = mobile_networks;
}

I could fix this error. In my case, the problem was at client side. By mistake I did not close the stream that I was writing to server. I closed stream and it worked fine. Even the error sounds like server was not able to identify the end-of-input.

OutputStream out = new BufferedOutputStream(urlConnection.getOutputStream());
out.write(jsonstring.getBytes());
out.close() ; //This is what I did

Improving Maxime's anwser:

docker ps --size

You'll see something like this:

+---------------+---------------+--------------------+
| CONTAINER ID  | IMAGE         | SIZE               |
+===============+===============+====================+
| 6ca0cef8db8d  | nginx         | 2B (virtual 183MB) |
| 3ab1a4d8dc5a  | nginx         | 5B (virtual 183MB) |
+---------------+---------------+--------------------+

When starting a container, the image that the container is started from is mounted read-only (virtual).
On top of that, a writable layer is mounted, in which any changes made to the container are written.

So the Virtual size (183MB in the example) is used only once, regardless of how many containers are started from the same image - I can start 1 container or a thousand; no extra disk space is used.
The "Size" (2B in the example) is unique per container though, so the total space used on disk is:

183MB + 5B + 2B

Be aware that the size shown does not include all disk space used for a container.
Things that are not included currently are;
- volumes
- swapping
- checkpoints
- disk space used for log-files generated by container

1. Execute the following code:

   import nltk
   nltk.download()
   

2. After this, NLTK downloader will pop out.

3. Select All packages.
4. Download punkt.

resize2fs Command will not work for all file systems.

Please confirm the file system of your instance using below command.

Please follow the procedure to expand volume by following the steps mentioned in Amazon official document for different file systems.

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/recognize-expanded-volume-linux.html

Default file system in Centos is xfs, use the following command for xfs file system to increase partition size.

sudo xfs_growfs -d /

then "df -h" to check.

Your json contains an array, but you're trying to parse it as an object. This error occurs because objects must start with {.

You have 2 options:

1. You can get rid of the ShopContainer class and use Shop[] instead

   ShopContainer response  = restTemplate.getForObject(
       url, ShopContainer.class);
   

   replace with

   Shop[] response  = restTemplate.getForObject(url, Shop[].class);
   

   and then make your desired object from it.

2. You can change your server to return an object instead of a list

   return mapper.writerWithDefaultPrettyPrinter().writeValueAsString(list);
   

   replace with

   return mapper.writerWithDefaultPrettyPrinter().writeValueAsString(
       new ShopContainer(list));
   

You need to do the following:

public class CountryInfoResponse {

   @JsonProperty("geonames")
   private List<Country> countries; 

   //getter - setter
}

RestTemplate restTemplate = new RestTemplate();
List<Country> countries = restTemplate.getForObject("http://api.geonames.org/countryInfoJSON?username=volodiaL",CountryInfoResponse.class).getCountries();

It would be great if you could use some kind of annotation to allow you to skip levels, but it's not yet possible (see this and this)

Here is a simple solution

try adding this dependency

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.8.3</version>
</dependency>

You can execute the following commands

lsof / |grep deleted

kill the process id's, which free up the disk space.

The way I am doing is using Emacs with docker package installed. I would recommend Spacemacs version of Emacs. I would follow the following steps:

1) Install Emacs (Instruction) and install Spacemacs (Instruction)

2) Add docker in your .spacemacs file

3) Start Emacs

4) Find file (SPC+f+f) and type /docker:<container-id>:/<path of dir/file in the container>

5) Now your emacs will use the container environment to edit the files

Am I the only one who finds unwinding lists boring? ;-)

Let's try with objects. Real world example by the way.

Given: Object representing repetitive task. About important task fields: reminders are starting to ring at start and repeat every repeatPeriod repeatUnit(e.g. 5 HOURS) and there will be repeatCount reminders in total(including starting one).

Goal: achieve a list of task copies, one for each task reminder invocation.

List<Task> tasks =
            Arrays.asList(
                    new Task(
                            false,//completed sign
                            "My important task",//task name (text)
                            LocalDateTime.now().plus(2, ChronoUnit.DAYS),//first reminder(start)
                            true,//is task repetitive?
                            1,//reminder interval
                            ChronoUnit.DAYS,//interval unit
                            5//total number of reminders
                    )
            );

tasks.stream().flatMap(
        x -> LongStream.iterate(
                x.getStart().toEpochSecond(ZoneOffset.UTC),
                p -> (p + x.getRepeatPeriod()*x.getRepeatUnit().getDuration().getSeconds())
        ).limit(x.getRepeatCount()).boxed()
        .map( y -> new Task(x,LocalDateTime.ofEpochSecond(y,0,ZoneOffset.UTC)))
).forEach(System.out::println);

Output:

Task{completed=false, text='My important task', start=2014-10-01T21:35:24, repeat=false, repeatCount=0, repeatPeriod=0, repeatUnit=null}
Task{completed=false, text='My important task', start=2014-10-02T21:35:24, repeat=false, repeatCount=0, repeatPeriod=0, repeatUnit=null}
Task{completed=false, text='My important task', start=2014-10-03T21:35:24, repeat=false, repeatCount=0, repeatPeriod=0, repeatUnit=null}
Task{completed=false, text='My important task', start=2014-10-04T21:35:24, repeat=false, repeatCount=0, repeatPeriod=0, repeatUnit=null}
Task{completed=false, text='My important task', start=2014-10-05T21:35:24, repeat=false, repeatCount=0, repeatPeriod=0, repeatUnit=null}

P.S.: I would appreciate if someone suggested a simpler solution, I'm not a pro after all.

UPDATE: @RBz asked for detailed explanation so here it is. Basically flatMap puts all elements from streams inside another stream into output stream. A lot of streams here :). So, for each Task in initial stream lambda expression x -> LongStream.iterate... creates a stream of long values that represent task start moments. This stream is limited to x.getRepeatCount() instances. It's values start from x.getStart().toEpochSecond(ZoneOffset.UTC) and each next value is calculated using lambda p -> (p + x.getRepeatPeriod()*x.getRepeatUnit().getDuration().getSeconds(). boxed() returns the stream with each long value as a Long wrapper instance. Then each Long in that stream is mapped to new Task instance that is not repetitive anymore and contains exact execution time. This sample contains only one Task in input list. But imagine that you have a thousand. You will have then a stream of 1000 streams of Task objects. And what flatMap does here is putting all Tasks from all streams onto the same output stream. That's all as I understand it. Thank you for your question!

The best way to convert it to HashMap<String, Object> is this:

HashMap<String, Object> result = new ObjectMapper().readValue(jsonString, new TypeReference<Map<String, Object>>(){}));

I would use null to show that there is no value for that particular key. For example, use null to represent that "number of devices in your household connects to internet" is unknown.

On the other hand, use {} if that particular key is not applicable. For example, you should not show a count, even if null, to the question "number of cars that has active internet connection" is asked to someone who does not own any cars.

I would avoid defaulting any value unless that default makes sense. While you may decide to use null to represent no value, certainly never use "null" to do so.

I can't comment on the accepted answer, due to low reputation. However, I would like to add, this behavior is by design. The NodeManager is killing your container. It sounds like you are trying to use hadoop streaming which is running as a child process of the map-reduce task. The NodeManager monitors the entire process tree of the task and if it eats up more memory than the maximum set in mapreduce.map.memory.mb or mapreduce.reduce.memory.mb respectively, we would expect the Nodemanager to kill the task, otherwise your task is stealing memory belonging to other containers, which you don't want.

In Jackson 2.4, you can convert as follows:

MyClass newJsonNode = jsonObjectMapper.treeToValue(someJsonNode, MyClass.class);

where jsonObjectMapper is a Jackson ObjectMapper.

In older versions of Jackson, it would be

MyClass newJsonNode = jsonObjectMapper.readValue(someJsonNode, MyClass.class);

As mentioned in the comments to the question, the JDBC-ODBC Bridge is - as the name indicates - only a mechanism for the JDBC layer to "talk to" the ODBC layer. Even if you had a JDBC-ODBC Bridge on your Mac you would also need to have

• an implementation of ODBC itself, and
• an appropriate ODBC driver for the target database (ACE/Jet, a.k.a. "Access")

So, for most people, using JDBC-ODBC Bridge technology to manipulate ACE/Jet ("Access") databases is really a practical option only under Windows. It is also important to note that the JDBC-ODBC Bridge will be has been removed in Java 8 (ref: here).

There are other ways of manipulating ACE/Jet databases from Java, such as UCanAccess and Jackcess. Both of these are pure Java implementations so they work on non-Windows platforms. For details on how to use UCanAccess see

Manipulating an Access database from Java without ODBC

Data content is so variable, I think the best form is to define it as "ObjectNode" and next create his own class to parse:

Finally:

private ObjectNode data;

Your JSON string is malformed: the type of center is an array of invalid objects. Replace [ and ] with { and } in the JSON string around longitude and latitude so they will be objects:

[
    {
        "name" : "New York",
        "number" : "732921",
        "center" : {
                "latitude" : 38.895111, 
                "longitude" : -77.036667
            }
    },
    {
        "name" : "San Francisco",
        "number" : "298732",
        "center" : {
                "latitude" : 37.783333, 
                "longitude" : -122.416667
            }
    }
]

you have a ObjectMapper (from Jackson Databind package) handy. if so, you can do:

JsonFactory factory = objectMapper.getFactory();

Source: https://github.com/FasterXML/jackson-core

So, the 3 "fasterxml" dependencies which you already have in u'r pom are enough for ObjectMapper as it includes jackson-databind.

    public static void main(String args[]) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

        int l;
        System.out.print("Enter any sentence: ");
        s = br.readLine();
        s = " " + s; //adding a space infront of the inputted sentence or a name
        s = s.toUpperCase(); //converting the sentence into Upper Case (Capital Letters)
        l = s.length(); //finding the length of the sentence
        System.out.print("Output = ");

        for (int i = 0; i < l; i++) {
            x = s.charAt(i); //taking out one character at a time from the sentence
            if (x == ' ') //if the character is a space, printing the next Character along with a fullstop
                System.out.print(s.charAt(i + 1) + ".");
        }
    }
}

The jackson API has changed:

new ObjectMapper()
.writer()
.withDefaultPrettyPrinter()
.writeValueAsString(new HashMap<String, Object>());

Yes, the Jackson manual parser design is quite different from other libraries. In particular, you will notice that JsonNode has most of the functions that you would typically associate with array nodes from other API's. As such, you do not need to cast to an ArrayNode to use. Here's an example:

JSON:

{
    "objects" : ["One", "Two", "Three"]
}

Code:

final String json = "{\"objects\" : [\"One\", \"Two\", \"Three\"]}";

final JsonNode arrNode = new ObjectMapper().readTree(json).get("objects");
if (arrNode.isArray()) {
    for (final JsonNode objNode : arrNode) {
        System.out.println(objNode);
    }
}

Output:

"One"
"Two"
"Three"

Note the use of isArray to verify that the node is actually an array before iterating. The check is not necessary if you are absolutely confident in your datas structure, but its available should you need it (and this is no different from most other JSON libraries).

Efran Cobisi's suggestion of using an Auto Mapper is a good one. I have used Auto Mapper for a while and it worked well, until I found the much faster alternative, Mapster.

Given a large list or IEnumerable, Mapster outperforms Auto Mapper. I found a benchmark somewhere that showed Mapster being 6 times as fast, but I could not find it again. You could look it up and then, if it is suits you, use Mapster.

You have the annotation in the wrong place - it needs to be on the class, not the field. i.e:

@JsonInclude(Include.NON_NULL) //or Include.NON_EMPTY, if that fits your use case 
public static class Request {
  // ...
}

As noted in comments, in versions below 2.x the syntax for this annotation is:

@JsonSerialize(include = JsonSerialize.Inclusion.NON_NULL) // or JsonSerialize.Inclusion.NON_EMPTY

The other option is to configure the ObjectMapper directly, simply by calling mapper.setSerializationInclusion(Include.NON_NULL);

(for the record, I think the popularity of this answer is an indication that this annotation should be applicable on a field-by-field basis, @fasterxml)

Here's how to change the dosbox.conf file in Linux to increase the size of the window. I actually DID what follows, so I can say it works (in 32-bit PCLinuxOS fullmontyKDE, anyway). The question's answer is in the .conf file itself.

You find this file in Linux at /home/(username)/.dosbox . In Konqueror or Dolphin, you must first check 'Hidden files' or you won't see the folder. Open it with KWrite superuser or your fav editor.

1. Save the file with another name like 'dosbox-0.74original.conf' to preserve the original file in case you need to restore it.
2. Search on 'resolution' and carefully read what the conf file says about changing it. There are essentially two variables: resolution and output. You want to leave fullresolution alone for now. Your question was about WINDOW, not full. So look for windowresolution, see what the comments in conf file say you can do. The best suggestion is to use a bigger-window resolution like 900x800 (which is what I used on a 1366x768 screen), but NOT the actual resolution of your machine (which would make the window fullscreen, and you said you didn't want that). Be specific, replacing the 'windowresolution=original' with 'windowresolution=900x800' or other dimensions. On my screen, that doubled the window size just as it does with the max Font tab in Windows Properties (for the exe file; as you'll see below the ==== marks, 32-bit Windows doesn't need Dosbox).

Then, search on 'output', and as the instruction in the conf file warns, if and only if you have 'hardware scaling', change the default 'output=surface' to something else; he then lists the optional other settings. I changed it to 'output=overlay'. There's one other setting to test: aspect. Search the file for 'aspect', and change the 'false' to 'true' if you want an even bigger window. When I did this, the window took up over half of the screen. With 'false' left alone, I had a somewhat smaller window (I use widescreen monitors, whether laptop or desktop, maybe that's why).

So after you've made the changes, save the file with the original name of dosbox-0.74.conf . Then, type dosbox at the command line or create a Launcher (in KDE, this is a right click on the desktop) with the command dosbox. You still have to go through the mount command (i.e., mount c~ c:\123 if that's the location and file you'll execute). I'm sure there's a way to make a script, but haven't yet learned how to do that.

You have to change the line

product userFromJSON = mapper.readValue(userDataJSON, product.class);

to

product[] userFromJSON = mapper.readValue(userDataJSON, product[].class);

since you are deserializing an array (btw: you should start your class names with upper case letters as mentioned earlier). Additionally you have to create setter methods for your fields or mark them as public in order to make this work.

Edit: You can also go with Steven Schlansker's suggestion and use

List<product> userFromJSON =
        mapper.readValue(userDataJSON, new TypeReference<List<product>>() {});

instead if you want to avoid arrays.

I created a new AutomapperProfile class. It extends Profile. We have over 100 projects in our solution. Many projects have an AutomapperProfile class, but this one was new to this existing project. However, I did find what I had to do to fix this issue for us. There is a Binding project. Within the Initialization there is this code:

var mappingConfig = new List<Action<IConfiguration>>();

// Initialize the Automapper Configuration for all Known Assemblies
mappingConfig.AddRange( new List<Action<IConfiguration>>
{
   ConfigureProfilesInAssemblyOfType<Application.Administration.AutomapperProfile>,
   //...

I had to add ConfigureProfilesInAssemblyOfType<MyNewNamespace.AutomapperProfile>

Note that ConfigureProfilesInAssemblyOfType looks like this:

    private static void ConfigureProfilesInAssemblyOfType<T>( IConfiguration configuration )
    {
        var log = LogProvider.Get( typeof (AutomapperConfiguration) );

        // The Automapper Profile Type
        var automapperProfileType = typeof (Profile);

        // The Assembly containing the type
        var assembly = typeof (T).Assembly;
        log.Debug( "Scanning " + assembly.FullName );

        // Configure any Profile classes found in the assembly containing the type.
        assembly.GetTypes()
            .Where( automapperProfileType.IsAssignableFrom ).ToList()
            .ForEach( x =>
            {
                log.Debug( "Adding Profile '" + x.FullName + "'" );
                configuration.AddProfile( Activator.CreateInstance( x ) as Profile );
            } );
    }

Best regards, -Jeff

do you try

[{"name":"myEnterprise", "departments":["HR"]}]

the square brace is the key point.

This looks like it might be the answer to your question. It says it's using Spring, but I think that should still help you in your case. Let me inline the code here so it's more convenient:

import java.io.FileReader;

import org.codehaus.jackson.map.ObjectMapper;
import org.codehaus.jackson.map.ObjectWriter;

public class Foo
{
  public static void main(String[] args) throws Exception
  {
    ObjectMapper mapper = new ObjectMapper();
    MyClass myObject = mapper.readValue(new FileReader("input.json"), MyClass.class);
    // this is Jackson 1.x API only: 
    ObjectWriter writer = mapper.defaultPrettyPrintingWriter();
    // ***IMPORTANT!!!*** for Jackson 2.x use the line below instead of the one above: 
    // ObjectWriter writer = mapper.writer().withDefaultPrettyPrinter();
    System.out.println(writer.writeValueAsString(myObject));
  }
}

class MyClass
{
  String one;
  String[] two;
  MyOtherClass three;

  public String getOne() {return one;}
  void setOne(String one) {this.one = one;}
  public String[] getTwo() {return two;}
  void setTwo(String[] two) {this.two = two;}
  public MyOtherClass getThree() {return three;}
  void setThree(MyOtherClass three) {this.three = three;}
}

class MyOtherClass
{
  String four;
  String[] five;

  public String getFour() {return four;}
  void setFour(String four) {this.four = four;}
  public String[] getFive() {return five;}
  void setFive(String[] five) {this.five = five;}
}

In date '?', the '?' is a literal string with value ?, not a parameter placeholder, so your query does not have any parameters. The date is a shorthand cast from (literal) string to date. You need to replace date '?' with ? to actually have a parameter.

Also if you know it is a date, then use setDate(..) and not setString(..) to set the parameter.

This is overly complicated, Jackson handles lists via its writer methods just as well as it handles regular objects. This should work just fine for you, assuming I have not misunderstood your question:

public void writeListToJsonArray() throws IOException {  
    final List<Event> list = new ArrayList<Event>(2);
    list.add(new Event("a1","a2"));
    list.add(new Event("b1","b2"));

    final ByteArrayOutputStream out = new ByteArrayOutputStream();
    final ObjectMapper mapper = new ObjectMapper();

    mapper.writeValue(out, list);

    final byte[] data = out.toByteArray();
    System.out.println(new String(data));
}

For all you non-xml config folks:

ObjectMapper objMapper = new ObjectMapper().setSerializationInclusion(JsonInclude.Include.NON_NULL);
HttpMessageConverter msgConverter = new MappingJackson2HttpMessageConverter(objMapper);
restTemplate.setMessageConverters(Collections.singletonList(msgConverter));

Another easy way to handle this is to use the argument allowSetters=truein the annotation. This will allow the password to be deserialized into your dto but it will not serialize it into a response body that uses contains object.

example:

@JsonIgnoreProperties(allowSetters = true, value = {"bar"})
class Pojo{
    String foo;
    String bar;
}

Both foo and bar are populated in the object, but only foo is written into a response body.

Sometimes it is the simple things. In my case, I had an invalid url. I had left out a colon before the at sign (@). I had "jdbc:oracle:thin@//localhost" instead of "jdbc:oracle:thin:@//localhost" Hope this helps someone else with this issue.

As of Jackson 1.6, you can use:

JsonNode node = mapper.valueToTree(map);

or

JsonNode node = mapper.convertValue(object, JsonNode.class);

Source: is there a way to serialize pojo's directly to treemodel?

if you're using scala and know the generic type at compile time, but don't want to manually pass TypeReference everywhere in all your api l ayers, you can use the following code (with jackson 2.9.5):

def read[T](entityStream: InputStream)(implicit typeTag: WeakTypeTag[T]): T = {

    //nathang: all of this *crazy* scala reflection allows us to handle List[Seq[Map[Int,Value]]]] without passing
    // new TypeReference[List[Seq[Map[Int,Value]]]]](){} to the function

    def recursiveFindGenericClasses(t: Type): JavaType = {
      val current = typeTag.mirror.runtimeClass(t)

      if (t.typeArgs.isEmpty) {
        val noSubtypes = Seq.empty[Class[_]]
        factory.constructParametricType(current, noSubtypes:_*)
      }

      else {
        val genericSubtypes: Seq[JavaType] = t.typeArgs.map(recursiveFindGenericClasses)
        factory.constructParametricType(current, genericSubtypes:_*)
      }

    }

    val javaType = recursiveFindGenericClasses(typeTag.tpe)

    json.readValue[T](entityStream, javaType)
  }

which can be used like this:

read[List[Map[Int, SomethingToSerialize]]](inputStream)

If it's reasonable to alter the original Map data structure to be serialized to better represent the actual value wanted to be serialized, that's probably a decent approach, which would possibly reduce the amount of Jackson configuration necessary. For example, just remove the null key entries, if possible, before calling Jackson. That said...

To suppress serializing Map entries with null values:

Before Jackson 2.9

you can still make use of WRITE_NULL_MAP_VALUES, but note that it's moved to SerializationFeature:

mapper.configure(SerializationFeature.WRITE_NULL_MAP_VALUES, false);

Since Jackson 2.9

The WRITE_NULL_MAP_VALUES is deprecated, you can use the below equivalent:

mapper.setDefaultPropertyInclusion(
   JsonInclude.Value.construct(Include.ALWAYS, Include.NON_NULL))

To suppress serializing properties with null values, you can configure the ObjectMapper directly, or make use of the @JsonInclude annotation:

mapper.setSerializationInclusion(Include.NON_NULL);

or:

@JsonInclude(Include.NON_NULL)
class Foo
{
  public String bar;

  Foo(String bar)
  {
    this.bar = bar;
  }
}

To handle null Map keys, some custom serialization is necessary, as best I understand.

A simple approach to serialize null keys as empty strings (including complete examples of the two previously mentioned configurations):

import java.io.IOException;
import java.util.HashMap;
import java.util.Map;

import com.fasterxml.jackson.annotation.JsonInclude.Include;
import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.JsonSerializer;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.databind.SerializerProvider;

public class JacksonFoo
{
  public static void main(String[] args) throws Exception
  {
    Map<String, Foo> foos = new HashMap<String, Foo>();
    foos.put("foo1", new Foo("foo1"));
    foos.put("foo2", new Foo(null));
    foos.put("foo3", null);
    foos.put(null, new Foo("foo4"));

    // System.out.println(new ObjectMapper().writeValueAsString(foos));
    // Exception: Null key for a Map not allowed in JSON (use a converting NullKeySerializer?)

    ObjectMapper mapper = new ObjectMapper();
    mapper.configure(SerializationFeature.WRITE_NULL_MAP_VALUES, false);
    mapper.setSerializationInclusion(Include.NON_NULL);
    mapper.getSerializerProvider().setNullKeySerializer(new MyNullKeySerializer());
    System.out.println(mapper.writeValueAsString(foos));
    // output: 
    // {"":{"bar":"foo4"},"foo2":{},"foo1":{"bar":"foo1"}}
  }
}

class MyNullKeySerializer extends JsonSerializer<Object>
{
  @Override
  public void serialize(Object nullKey, JsonGenerator jsonGenerator, SerializerProvider unused) 
      throws IOException, JsonProcessingException
  {
    jsonGenerator.writeFieldName("");
  }
}

class Foo
{
  public String bar;

  Foo(String bar)
  {
    this.bar = bar;
  }
}

To suppress serializing Map entries with null keys, further custom serialization processing would be necessary.

This is due to Morphia jar not being part of your output war/jar. Eclipse or local build includes them as part of classpath, but remote builds or auto/scheduled build don't consider them part of classpath.

You can include dependent jars using plugin.

Add below snippet into your pom's plugins section

    <plugin>
        <artifactId>maven-assembly-plugin</artifactId>
        <version>3.0.0</version>
        <configuration>
            <descriptorRefs>
                <descriptorRef>jar-with-dependencies</descriptorRef>
            </descriptorRefs>
        </configuration>
    </plugin>

This is occurring due to how PHP treats overloaded properties in that they are not modifiable or passed by reference.

See the manual for more information regarding overloading.

To work around this problem you can either use a __set function or create a createObject method.

Below is a __get and __set that provides a workaround to a similar situation to yours, you can simply modify the __set to suite your needs.

Note the __get never actually returns a variable. and rather once you have set a variable in your object it no longer is overloaded.

/**
 * Get a variable in the event.
 *
 * @param  mixed  $key  Variable name.
 *
 * @return  mixed|null
 */
public function __get($key)
{
    throw new \LogicException(sprintf(
        "Call to undefined event property %s",
        $key
    ));
}

/**
 * Set a variable in the event.
 *
 * @param  string  $key  Name of variable
 *
 * @param  mixed  $value  Value to variable
 *
 * @return  boolean  True
 */
public function __set($key, $value)
{
    if (stripos($key, '_') === 0 && isset($this->$key)) {
        throw new \LogicException(sprintf(
            "%s is a read-only event property", 
            $key
        ));
    }
    $this->$key = $value;
    return true;
}

Which will allow for:

$object = new obj();
$object->a = array();
$object->a[] = "b";
$object->v = new obj();
$object->v->a = "b";

This seems like that the servlet api version which you using is older than the xsd you are using in web.xml eg 3.0

use this one ****http://java.sun.com/xml/ns/javaee/" id="WebApp_ID" version="2.5"> ****

You can deserialize directly to a list by using the TypeReference wrapper. An example method:

public static <T> T fromJSON(final TypeReference<T> type,
      final String jsonPacket) {
   T data = null;

   try {
      data = new ObjectMapper().readValue(jsonPacket, type);
   } catch (Exception e) {
      // Handle the problem
   }
   return data;
}

And is used thus:

final String json = "";
Set<POJO> properties = fromJSON(new TypeReference<Set<POJO>>() {}, json);

TypeReference Javadoc

If you have Model or transfer object passed to GET method but still have this error, check naming of your variables. Use entity/transfer object names in camelcase. I had BusinessTripDTO object and named it 'trip' for short. It caused this error to occure, even I had all other parts in place. Renaming varaibles to businessTripDTO in Java and Thymeleaf solved this problem for me.

java.lang.NoSuchMethodError: javax.servlet.ServletContext.getContextPath()Ljava/lang/String;

That method was added in Servlet 2.5.

So this problem can have at least 3 causes:

1. The servlet container does not support Servlet 2.5.
2. The web.xml is not declared conform Servlet 2.5 or newer.
3. The webapp's runtime classpath is littered with servlet container specific JAR files of a different servlet container make/version which does not support Servlet 2.5.

To solve it,

1. Make sure that your servlet container supports at least Servlet 2.5. That are at least Tomcat 6, Glassfish 2, JBoss AS 4.1, etcetera. Tomcat 5.5 for example supports at highest Servlet 2.4. If you can't upgrade Tomcat, then you'd need to downgrade Spring to a Servlet 2.4 compatible version.
2. Make sure that the root declaration of web.xml complies Servlet 2.5 (or newer, at least the highest whatever your target runtime supports). For an example, see also somewhere halfway our servlets wiki page.
3. Make sure that you don't have any servlet container specific libraries like servlet-api.jar or j2ee.jar in /WEB-INF/lib or even worse, the JRE/lib or JRE/lib/ext. They do not belong there. This is a pretty common beginner's mistake in an attempt to circumvent compilation errors in an IDE, see also How do I import the javax.servlet API in my Eclipse project?.

Here are the three options:

1. Data/class that's been accessed needs to be public
2. If not public, add getters & setters
3. Or add @JsonIgnore("context")

A late answer, but here is an alternative to the SCOPE_IDENTITY() answers that we ended up using: OUTPUT INSERTED

Return only ID of inserted object:

It allows you to get all or some attributes of the inserted row:

string insertUserSql = @"INSERT INTO dbo.[User](Username, Phone, Email)
                        OUTPUT INSERTED.[Id]
                        VALUES(@Username, @Phone, @Email);";

int newUserId = conn.QuerySingle<int>(
                                insertUserSql,
                                new
                                {
                                    Username = "lorem ipsum",
                                    Phone = "555-123",
                                    Email = "lorem ipsum"
                                },
                                tran);

Return inserted object with ID:

If you wanted you could get Phone and Email or even the whole inserted row:

string insertUserSql = @"INSERT INTO dbo.[User](Username, Phone, Email)
                        OUTPUT INSERTED.*
                        VALUES(@Username, @Phone, @Email);";

User newUser = conn.QuerySingle<User>(
                                insertUserSql,
                                new
                                {
                                    Username = "lorem ipsum",
                                    Phone = "555-123",
                                    Email = "lorem ipsum"
                                },
                                tran);

Also, with this you can return data of deleted or updated rows. Just be careful if you are using triggers because (from link mentioned before):

Columns returned from OUTPUT reflect the data as it is after the INSERT, UPDATE, or DELETE statement has completed but before triggers are executed.

For INSTEAD OF triggers, the returned results are generated as if the INSERT, UPDATE, or DELETE had actually occurred, even if no modifications take place as the result of the trigger operation. If a statement that includes an OUTPUT clause is used inside the body of a trigger, table aliases must be used to reference the trigger inserted and deleted tables to avoid duplicating column references with the INSERTED and DELETED tables associated with OUTPUT.

More on it in the docs: link

I am using Spring 3.2.4 and Jackson FasterXML 2.1.1.

I have created a custom JacksonObjectMapper that works with explicit annotations for each attribute of the Objects mapped:

package com.test;
import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;

public class MyJaxbJacksonObjectMapper extends ObjectMapper {

public MyJaxbJacksonObjectMapper() {

    this.setVisibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY)
            .setVisibility(PropertyAccessor.CREATOR, JsonAutoDetect.Visibility.ANY)
            .setVisibility(PropertyAccessor.SETTER, JsonAutoDetect.Visibility.NONE)
            .setVisibility(PropertyAccessor.GETTER, JsonAutoDetect.Visibility.NONE)
            .setVisibility(PropertyAccessor.IS_GETTER, JsonAutoDetect.Visibility.NONE);

    this.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);
    }
}

Then this is instantiated in the context-configuration (servlet-context.xml):

<mvc:annotation-driven>
    <mvc:message-converters>

        <beans:bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
            <beans:property name="objectMapper">
                <beans:bean class="com.test.MyJaxbJacksonObjectMapper" />
            </beans:property>
        </beans:bean>

    </mvc:message-converters>
</mvc:annotation-driven>

This works fine!

For Jackson 2+ (com.fasterxml.jackson), the methods are little bit different:

Iterator<Entry<String, JsonNode>> nodes = rootNode.get("foo").fields();

while (nodes.hasNext()) {
  Map.Entry<String, JsonNode> entry = (Map.Entry<String, JsonNode>) nodes.next();

  logger.info("key --> " + entry.getKey() + " value-->" + entry.getValue());
}

The other answer is correct, but for completeness, here are other ways:

List<SomeClass> list = mapper.readValue(jsonString, new TypeReference<List<SomeClass>>() { });
SomeClass[] array = mapper.readValue(jsonString, SomeClass[].class);

You can put @JsonSerialize(using = CustomDateSerializer.class) over any date field of object to be serialized.

public class CustomDateSerializer extends SerializerBase<Date> {

    public CustomDateSerializer() {
        super(Date.class, true);
    }

    @Override
    public void serialize(Date value, JsonGenerator jgen, SerializerProvider provider)
        throws IOException, JsonProcessingException {
        SimpleDateFormat formatter = new SimpleDateFormat("EEE MMM dd yyyy HH:mm:ss 'GMT'ZZZ (z)");
        String format = formatter.format(value);
        jgen.writeString(format);
    }

}

Specifically for boolean is*() getters:

I've spend a lot of time on why neither below

  @JsonAutoDetect(fieldVisibility = Visibility.ANY, getterVisibility = Visibility.NONE, setterVisibility = Visibility.NONE)

nor this

  setVisibility(PropertyAccessor.SETTER, JsonAutoDetect.Visibility.NONE);
  setVisibility(PropertyAccessor.GETTER, JsonAutoDetect.Visibility.NONE);
  setVisibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY);

worked for my Boolean Getter/Setter.

Solution is simple:

  @JsonAutoDetect(isGetterVisibility = Visibility.NONE, ...          
  setVisibility(PropertyAccessor.IS_GETTER, JsonAutoDetect.Visibility.NONE);

UPDATE: spring-boot allowed configure it:

jackson:
  visibility.field: any
  visibility.getter: none
  visibility.setter: none
  visibility.is-getter: none

See Common application properties # JACKSON

you could also create a class which extends ArrayList:

public static class MyList extends ArrayList<Myclass> {}

and then use it like:

List<MyClass> list = objectMapper.readValue(json, MyList.class);

I found a work around but with this I'll need to annotate each date's setter throughout the project. Is there a way in which I can specify the format while creating the ObjectMapper?

Here's what I did:

public class CustomJsonDateDeserializer extends JsonDeserializer<Date>
{
    @Override
    public Date deserialize(JsonParser jsonParser,
            DeserializationContext deserializationContext) throws IOException, JsonProcessingException {

        SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
        String date = jsonParser.getText();
        try {
            return format.parse(date);
        } catch (ParseException e) {
            throw new RuntimeException(e);
        }

    }

}

And annotated each Date field's setter method with this:

@JsonDeserialize(using = CustomJsonDateDeserializer.class)

When mapping a view model back to a domain model, it can be much cleaner to simply validate the source member list rather than the destination member list

Mapper.CreateMap<OrderModel, Orders>(MemberList.Source); 

Now my mapping validation doesn't fail, requiring another Ignore(), every time I add a property to my domain class.

AngerClown pointed me to the right direction.

This is what I finally did, just in case anyone find it useful.

I still have to figure out how to configure the other properties such as:

om.configure(JsonGenerator.Feature.QUOTE_FIELD_NAMES, true);

Your input

{"wrapper":[{"id":"13","name":"Fred"}]}

indicates that it is an Object, with a field named "wrapper", which is a Collection of Students. So my recommendation would be,

Wrapper = mapper.readValue(jsonStr , Wrapper.class);

where Wrapper is defined as

class Wrapper {
    List<Student> wrapper;
}

i got the same error, but with no relation to Hibernate. I got scared here from all frightening suggestions, which i guess relevant in case of Hibernate and lazy loading... However, in my case i got the error since in an inner class i had no getters/setters, so the BeanSerializer could not serialize the data...

Adding getters & setters resolved the problem.

The simplest way to find out it.

import os
from collections import namedtuple

DiskUsage = namedtuple('DiskUsage', 'total used free')

def disk_usage(path):
    """Return disk usage statistics about the given path.

    Will return the namedtuple with attributes: 'total', 'used' and 'free',
    which are the amount of total, used and free space, in bytes.
    """
    st = os.statvfs(path)
    free = st.f_bavail * st.f_frsize
    total = st.f_blocks * st.f_frsize
    used = (st.f_blocks - st.f_bfree) * st.f_frsize
    return DiskUsage(total, used, free)

Perhaps the project's type table is in an incorrect state. I would try to remove/add the reference and if that didn't work, create another project, import my code, and see if that works.

I ran into this while using VS 2005, one would expect MS to have fixed that particular problem by now though..

com.fasterxml.jackson.databind.type.TypeFactory._hashMapSuperInterfaceChain(HierarchicType)

com.fasterxml.jackson.databind.type.TypeFactory._findSuperInterfaceChain(Type, Class)
  com.fasterxml.jackson.databind.type.TypeFactory._findSuperTypeChain(Class, Class)
     com.fasterxml.jackson.databind.type.TypeFactory.findTypeParameters(Class, Class, TypeBindings)
        com.fasterxml.jackson.databind.type.TypeFactory.findTypeParameters(JavaType, Class)
           com.fasterxml.jackson.databind.type.TypeFactory._fromParamType(ParameterizedType, TypeBindings)
              com.fasterxml.jackson.databind.type.TypeFactory._constructType(Type, TypeBindings)
                 com.fasterxml.jackson.databind.type.TypeFactory.constructType(TypeReference)
                    com.fasterxml.jackson.databind.ObjectMapper.convertValue(Object, TypeReference)

The method _hashMapSuperInterfaceChain in class com.fasterxml.jackson.databind.type.TypeFactory is synchronized. Am seeing contention on the same at high loads.

May be another reason to avoid a static ObjectMapper

as the exception says there is already another server running on the same port. you can either kill that service or change glassfish to run on another poet

I had the same problem, and the solution for me was to allow Maven to handle all dependencies, including to local jars. I used Maven for online dependencies, and configured build path manually for local dependencies. Thus, Maven was not aware of the dependencies I configured manually.

I used this solution to install the local jar dependencies into Maven:

How to add local jar files in maven project?

<htmltag id=’elementId’ data-ZZZZ’=’@Html.Raw(Json.Encode(Model))’ />

Refer https://highspeedlowdrag.wordpress.com/2014/08/23/mvc-data-to-jquery-data/

I did below and it works like charm.

<input id="hdnElement" class="hdnElement" type="hidden" value='@Html.Raw(Json.Encode(Model))'>

Meanwhile Jackson registers the Joda module automatically when the JodaModule is in classpath. I just added jackson-datatype-joda to Maven and it worked instantly.

<dependency>
  <groupId>com.fasterxml.jackson.datatype</groupId>
  <artifactId>jackson-datatype-joda</artifactId>
  <version>2.8.7</version>
</dependency>

JSON output:

{"created" : "2017-03-28T05:59:27.258Z"}

Looks like you have a dos line ending file. The clue is the ^M.

You need to re-save the file using Unix line endings.

You might have a dos2unix command line utility that will also do this for you.

You can easily import your model and run this:

from models import User

# User is the name of table that has a column name
users = User.query.all()

for user in users:
    print user.name

Your __init__.py should have a docstring.

Although all the functionality is implemented in modules and subpackages, your package docstring is the place to document where to start. For example, consider the python email package. The package documentation is an introduction describing the purpose, background, and how the various components within the package work together. If you automatically generate documentation from docstrings using sphinx or another package, the package docstring is exactly the right place to describe such an introduction.

For any other content, see the excellent answers by firecrow and Alex Martelli.

You can use git log with the pathnames of the respective folders:

git log A B

The log will only show commits made in A and B. I usually throw in --stat to make things a little prettier, which helps for quick commit reviews.

In addition to the pure javascript answers above, You can use jQuery text method as following:

$('#myspan').text('newtext');

If you need to extend the answer to get/change html content of a span or div elements, you can do this:

$('#mydiv').html('<strong>new text</strong>');

References:

.text(): http://api.jquery.com/text/

.html(): http://api.jquery.com/html/

Well one solution could be:

list.get(list.size()-1)

Edit: You have to convert the collection to a list before maybe like this: new ArrayList(coll)

It seems to have to do with context wrapping. Most classes derived from Context are actually a ContextWrapper, which essentially delegates to another context, possibly with changes by the wrapper.

The context is a general abstraction that supports mocking and proxying. Since many contexts are bound to a limited-lifetime object such as an Activity, there needs to be a way to get a longer-lived context, for purposes such as registering for future notifications. That is achieved by Context.getApplicationContext(). A logical implementation is to return the global Application object, but nothing prevents a context implementation from returning a wrapper or proxy with a suitable lifetime instead.

Activities and services are more specifically associated with an Application object. The usefulness of this, I believe, is that you can create and register in the manifest a custom class derived from Application and be certain that Activity.getApplication() or Service.getApplication() will return that specific object of that specific type, which you can cast to your derived Application class and use for whatever custom purpose.

In other words, getApplication() is guaranteed to return an Application object, while getApplicationContext() is free to return a proxy instead.

I found the simplest solution is to add two registry entries as follows (run this in a command prompt with admin privileges):

reg add HKLM\SOFTWARE\Microsoft\.NETFramework\v4.0.30319 /v SchUseStrongCrypto /t REG_DWORD /d 1 /reg:32

reg add HKLM\SOFTWARE\Microsoft\.NETFramework\v4.0.30319 /v SchUseStrongCrypto /t REG_DWORD /d 1 /reg:64

These entries seem to affect how the .NET CLR chooses a protocol when making a secure connection as a client.

There is more information about this registry entry here:

https://docs.microsoft.com/en-us/security-updates/SecurityAdvisories/2015/2960358#suggested-actions

Not only is this simpler, but assuming it works for your case, far more robust than a code-based solution, which requires developers to track protocol and development and update all their relevant code. Hopefully, similar environment changes can be made for TLS 1.3 and beyond, as long as .NET remains dumb enough to not automatically choose the highest available protocol.

NOTE: Even though, according to the article above, this is only supposed to disable RC4, and one would not think this would change whether the .NET client is allowed to use TLS1.2+ or not, for some reason it does have this effect.

NOTE: As noted by @Jordan Rieger in the comments, this is not a solution for POODLE, since it does not disable the older protocols a -- it merely allows the client to work with newer protocols e.g. when a patched server has disabled the older protocols. However, with a MITM attack, obviously a compromised server will offer the client an older protocol, which the client will then happily use.

TODO: Try to disable client-side use of TLS1.0 and TLS1.1 with these registry entries, however I don't know if the .NET http client libraries respect these settings or not:

https://docs.microsoft.com/en-us/windows-server/security/tls/tls-registry-settings#tls-10

https://docs.microsoft.com/en-us/windows-server/security/tls/tls-registry-settings#tls-11

Session.Clear();

This is already been answered right but i think i should give my opinion too. Like cozen says this is a border, and for it to work you must specify the classes to format this in the same way that bootstrap specifies it. So, you can do this

.tooltip .tooltip-inner {background-color: #00a8c4; color: black;} 
.tooltip.top .tooltip-arrow {border-top-color: #00a8c4;}

or you can do the next one, just for the tooltip-arrow but you must add the !important, so that it overwrites the bootstrap css

.tooltip-arrow {border-top-color: #00a8c4!important;}

XDebug changed some configuration settings.

Old settings:

xdebug.remote_enable = 1
xdebug.remote_autostart = 1
xdebug.remote_port = 9000

New settings:

xdebug.mode=debug
xdebug.start_with_request=yes
xdebug.client_port=9000

So you should paste the latter in php.ini file. More info: XDebug Changed Configuration Settings

There is no built-in way. You can have MyClass implement the IClonable interface (but it is sort of deprecated) or just write your own Copy/Clone method. In either case you will have to write some code.

For big objects you could consider Serialization + Deserialization (through a MemoryStream), just to reuse existing code.

Whatever the method, think carefully about what "a copy" means exactly. How deep should it go, are there Id fields to be excepted etc.

I found this maven repo where you could download from directly a zip file containing all the jars you need.

• https://maven.springframework.org/release/org/springframework/spring/
• https://repo.spring.io/release/org/springframework/spring/

Alternate solution: Maven

The solution I prefer is using Maven, it is easy and you don't have to download each jar alone. You can do it with the following steps:

1. Create an empty folder anywhere with any name you prefer, for example spring-source

2. Create a new file named pom.xml

3. Copy the xml below into this file

4. Open the spring-source folder in your console

5. Run mvn install

6. After download finished, you'll find spring jars in /spring-source/target/dependencies

   <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Also, if you need to download any other spring project, just copy the dependency configuration from its corresponding web page.

For example, if you want to download Spring Web Flow jars, go to its web page, and add its dependency configuration to the pom.xml dependencies, then run mvn install again.

DOM event delegation is a mechanism of responding to ui-events via a single common parent rather than each child, through the magic of event "bubbling" (aka event propagation).

When an event is triggered on an element, the following occurs:

The event is dispatched to its target EventTarget and any event listeners found there are triggered. Bubbling events will then trigger any additional event listeners found by following the EventTarget's parent chain upward, checking for any event listeners registered on each successive EventTarget. This upward propagation will continue up to and including the Document.

Event bubbling provides the foundation for event delegation in browsers. Now you can bind an event handler to a single parent element, and that handler will get executed whenever the event occurs on any of its child nodes (and any of their children in turn). This is event delegation. Here's an example of it in practice:

<ul onclick="alert(event.type + '!')">
    <li>One</li>
    <li>Two</li>
    <li>Three</li>
</ul>

With that example if you were to click on any of the child <li> nodes, you would see an alert of "click!", even though there is no click handler bound to the <li> you clicked on. If we bound onclick="..." to each <li> you would get the same effect.

So what's the benefit?

Imagine you now have a need to dynamically add new <li> items to the above list via DOM manipulation:

var newLi = document.createElement('li');
newLi.innerHTML = 'Four';
myUL.appendChild(newLi);

Without using event delegation you would have to "rebind" the "onclick" event handler to the new <li> element, in order for it to act the same way as its siblings. With event delegation you don't need to do anything. Just add the new <li> to the list and you're done.

This is absolutely fantastic for web apps with event handlers bound to many elements, where new elements are dynamically created and/or removed in the DOM. With event delegation the number of event bindings can be drastically decreased by moving them to a common parent element, and code that dynamically creates new elements on the fly can be decoupled from the logic of binding their event handlers.

Another benefit to event delegation is that the total memory footprint used by event listeners goes down (since the number of event bindings go down). It may not make much of a difference to small pages that unload often (i.e. user's navigate to different pages often). But for long-lived applications it can be significant. There are some really difficult-to-track-down situations when elements removed from the DOM still claim memory (i.e. they leak), and often this leaked memory is tied to an event binding. With event delegation you're free to destroy child elements without risk of forgetting to "unbind" their event listeners (since the listener is on the ancestor). These types of memory leaks can then be contained (if not eliminated, which is freaking hard to do sometimes. IE I'm looking at you).

Here are some better concrete code examples of event delegation:

• How JavaScript Event Delegation Works
• Event Delegation versus Event Handling
• jQuery.delegate is event delegation + selector specification
• jQuery.on uses event delegation when passed a selector as the 2nd parameter
• Event delegation without a JavaScript library
• Closures vs Event delegation: takes a look at the pros of not converting code to use event delegation
• Interesting approach PPK uncovered for delegating the focus and blur events (which do not bubble)

I wanted to extend the answers already given to include support for dynamically connected devices that aren't captured with /dev/bus/usb and how to get this working when using a Windows host along with the boot2docker VM.

If you are working with Windows, you'll need to add any USB rules for devices that you want Docker to access within the VirtualBox manager. To do this you can stop the VM by running:

host:~$ docker-machine stop default

Open the VirtualBox Manager and add USB support with filters as required.

Start the boot2docker VM:

host:~$ docker-machine start default

Since the USB devices are connected to the boot2docker VM, the commands need to be run from that machine. Open up a terminal with the VM and run the docker run command:

host:~$ docker-machine ssh
docker@default:~$ docker run -it --privileged ubuntu bash

Note, when the command is run like this, then only previously connected USB devices will be captures. The volumes flag is only required if you want this to work with devices connected after the container is started. In that case, you can use:

docker@default:~$ docker run -it --privileged -v /dev:/dev ubuntu bash

Note, I had to use /dev instead of /dev/bus/usb in some cases to capture a device like /dev/sg2. I can only assume the same would be true for devices like /dev/ttyACM0 or /dev/ttyUSB0.

The docker run commands will work with a Linux host as well.

The best solution, where en is the English locale:

fraction.toLocaleString("en", {style: "percent"})

I think your problem is your version numbers. Try making 8.1 --> 8.01, and so forth. That should put the points in the right order.

Alternatively, you could plot using X, where X is the column number you want, instead of using 1:X. That will plot those values on the y axis and integers on the x axis. Try:

plot "ls.dat" using 2 title 'Removed' with lines, \
     "ls.dat" using 3 title 'Added' with lines, \
     "ls.dat" using 4 title 'Modified' with lines

I recently had this error and found that the problem was caused by the feature "HTTP Redirection" not being enabled on my Windows Server. This blog post helped me get through troubleshooting to find the answer (despite being older Windows Server versions): http://blogs.msdn.com/b/rjacobs/archive/2010/06/30/system-web-routing-routetable-not-working-with-iis.aspx for newer servers go to Computer management, then scroll down to the Web Server role and click add role services

You should go to Control Panel -> Programs and Features, find Microsoft Visual Studio 2015 and select "Change". Visual Studio 2015 setup will start. Select "Modify".

In Visual Studio components list, open the list of sub-items and select "ClickOnce Publication Tools" and "Windows 10 SDK" too.

Solution using just POST - no $_SESSION

page1.php

<form action="page2.php" method="post">
    <textarea name="textarea1" id="textarea1"></textarea><br />
    <input type="submit" value="submit" />
</form>

page2.php

<?php
    // this page outputs the contents of the textarea if posted
    $textarea1 = ""; // set var to avoid errors
    if(isset($_POST['textarea1'])){
        $textarea1 = $_POST['textarea1']
    }
?>
<textarea><?php echo $textarea1;?></textarea>

Solution using $_SESSION and POST

page1.php

<?php

    session_start(); // needs to be before anything else on page to use $_SESSION
    $textarea1 = "";
    if(isset($_POST['textarea1'])){
        $_SESSION['textarea1'] = $_POST['textarea1'];
    }

?>


<form action="page1.php" method="post">
    <textarea name="textarea1" id="textarea1"></textarea><br />
    <input type="submit" value="submit" />
</form>
<br /><br />
<a href="page2.php">Go to page2</a>

page2.php

<?php
    session_start(); // needs to be before anything else on page to use $_SESSION
    // this page outputs the textarea1 from the session IF it exists
    $textarea1 = ""; // set var to avoid errors
    if(isset($_SESSION['textarea1'])){
        $textarea1 = $_SESSION['textarea1']
    }
?>
<textarea><?php echo $textarea1;?></textarea>

This command helps you to unlock phone using ADB

The real answer is : It depends

There are a couple factors to consider, the most obvious are : the cpu you are running these algorithms on and the implementation of the algorithms.

For instance, me and my friend both run the exact same openssl version and get slightly different results with different Intel Core i7 cpus.

My test at work with an Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz

The 'numbers' are in 1000s of bytes per second processed.
type             16 bytes     64 bytes    256 bytes   1024 bytes   8192 bytes
md5              64257.97k   187370.26k   406435.07k   576544.43k   649827.67k
sha1             73225.75k   202701.20k   432679.68k   601140.57k   679900.50k

And his with an Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz

The 'numbers' are in 1000s of bytes per second processed.
type             16 bytes     64 bytes    256 bytes   1024 bytes   8192 bytes
md5              51859.12k   156255.78k   350252.00k   513141.73k   590701.52k
sha1             56492.56k   156300.76k   328688.76k   452450.92k   508625.68k

We both are running the exact same binaries of OpenSSL 1.0.1j 15 Oct 2014 from the ArchLinux official package.

My opinion on this is that with the added security of sha1, cpu designers are more likely to improve the speed of sha1 and more programmers will be working on the algorithm's optimization than md5sum.

I guess that md5 will no longer be used some day since it seems that it has no advantage over sha1. I also tested some cases on real files and the results were always the same in both cases (likely limited by disk I/O).

md5sum of a large 4.6GB file took the exact same time than sha1sum of the same file, same goes with many small files (488 in the same directory). I ran the tests a dozen times and they were consitently getting the same results.

It would be very interesting to investigate this further. I guess there are some experts around that could provide a solid answer to why sha1 is getting faster than md5 on newer processors.

A more concise, elegant, and secure answer: add “?enablejsapi=1” to the end of the video URL, then construct and stringify an ordinary object representing the pause command:

const YouTube_pause_video_command_JSON = JSON.stringify(Object.create(null, {
    "event": {
        "value": "command",
        "enumerable": true
    },
    "func": {
        "value": "pauseVideo",
        "enumerable": true
    }
}));

Use the Window.postMessage method to send the resulting JSON string to the embedded video document:

// |iframe_element| is defined elsewhere.
const video_URL = iframe_element.getAttributeNS(null, "src");
iframe_element.contentWindow.postMessage(YouTube_pause_video_command_JSON, video_URL);

Make sure you specify the video URL for the Window.postMessage method’s targetOrigin argument to ensure that your messages won’t be sent to any unintended recipient.

Here is a very quick (and semi-dirty) implementation of Bedwyr Humphreys's answer. The interface should be compatible with @matt's answer as well, but uses decimal instead of int and uses more IEnumerable concepts to hopefully make it easier to use and read.

Slope is b, Intercept is a

public class Trendline
{
    public Trendline(IList<decimal> yAxisValues, IList<decimal> xAxisValues)
        : this(yAxisValues.Select((t, i) => new Tuple<decimal, decimal>(xAxisValues[i], t)))
    { }
    public Trendline(IEnumerable<Tuple<Decimal, Decimal>> data)
    {
        var cachedData = data.ToList();

        var n = cachedData.Count;
        var sumX = cachedData.Sum(x => x.Item1);
        var sumX2 = cachedData.Sum(x => x.Item1 * x.Item1);
        var sumY = cachedData.Sum(x => x.Item2);
        var sumXY = cachedData.Sum(x => x.Item1 * x.Item2);

        //b = (sum(x*y) - sum(x)sum(y)/n)
        //      / (sum(x^2) - sum(x)^2/n)
        Slope = (sumXY - ((sumX * sumY) / n))
                    / (sumX2 - (sumX * sumX / n));

        //a = sum(y)/n - b(sum(x)/n)
        Intercept = (sumY / n) - (Slope * (sumX / n));

        Start = GetYValue(cachedData.Min(a => a.Item1));
        End = GetYValue(cachedData.Max(a => a.Item1));
    }

    public decimal Slope { get; private set; }
    public decimal Intercept { get; private set; }
    public decimal Start { get; private set; }
    public decimal End { get; private set; }

    public decimal GetYValue(decimal xValue)
    {
        return Intercept + Slope * xValue;
    }
}

Try C# 7.0

var Dob= DateTime.TryParseExact(s: YourDateString,format: "yyyyMMdd",provider: null,style: 0,out var dt)
 ? dt : DateTime.Parse("1800-01-01");

I would create a trigger that catches all updates/inserts/deletes and write timestamp in custom table, something like tablename | timestamp

Just because I don't like the idea to read internal system tables of db server directly

You forgot to add the global operator. Use this:

var s = "04.07.2012";_x000D_
alert(s.replace(new RegExp("[0-9]","g"), "X")); 

Thanks all for your help but it is not complicated as it seems; almost everything is handled internally by SpringBoot.

In my case I want to use Mysql and Mongodb and the solution was to use EnableMongoRepositories and EnableJpaRepositories annotations on to my application class.

@SpringBootApplication
@EnableTransactionManagement
@EnableMongoRepositories(includeFilters = @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = MongoRepository))
@EnableJpaRepositories(excludeFilters = @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = MongoRepository))
class TestApplication { ...

NB: All mysql entities have to extend JpaRepository and mongo enities have to extend MongoRepository.

The datasource configs are straight forward as presented by spring documentation:

//mysql db config
spring.datasource.url= jdbc:mysql://localhost:3306/tangio
spring.datasource.username=test
spring.datasource.password=test

#mongodb config
spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=tangio
spring.data.mongodb.username=tangio
spring.data.mongodb.password=tangio
spring.data.mongodb.repositories.enabled=true

That's because your hidden fields have duplicate IDs, so jQuery only returns the first in the set. Give them classes instead, like .uid and grab them via:

var uids = $(".uid").map(function() {
    return this.value;
}).get();

Demo: http://jsfiddle.net/karim79/FtcnJ/

EDIT: say your output looks like the following (notice, IDs have changed to classes)

<fieldset><legend>John Smith</legend>
<img src='foo.jpg'/><br>
<a href="#" class="aaf">add as friend</a>
<input name="uid" type="hidden" value='<?php echo $row->uid;?>' class="uid">
</fieldset>

You can target the 'uid' relative to the clicked anchor like this:

$("a.aaf").click(function() {
    alert($(this).next('.uid').val());
});

Important: do not have any duplicate IDs. They will cause problems. They are invalid, bad and you should not do it.

To be able to give you specific help, you's have to explain what particular parts specifically "get messed up", or perhaps offer a screenshot. It also helps to know what version of Outlook you encounter the problem in.

Either way, CampaignMonitor.com's CSS guide has often helped me out debugging email client inconsistencies.

From that guide you can see several things just won't work well or at all in Outlook, here are some highlights of the more important ones:

• Various types of more sophisticated selectors, e.g. E:first-child, E:hover, E > F (Child combinator), E + F (Adjacent sibling combinator), E ~ F (General sibling combinator). This unfortunately means resorting to workarounds like inline styles.
• Some font properties, e.g. white-space won't work.
• The background-image property won't work.
• There are several issues with the Box Model properties, most importantly height, width, and the max- versions are either not usable or have bugs for certain elements.
• Positioning and Display issues (e.g. display, floats and position are all out).

In short: combining CSS and Outlook can be a pain. Be prepared to use many ugly workarounds.

PS. In your specific case, there are two minor issues in your html that may cause you odd behavior. There's "align=top" where you probably meant to use vertical-align. Also: cell-padding for tds doesn't exist.

use datejs

new Date().toString('yyyy-MM-d-h-mm-ss');

More stable approach:

<form onsubmit="foo($("#formValueId").val());return false;">
<input type="text" id="formValueId"/>
<input type="submit" value="Text on the button"/>
</form>

The return false; is to prevent actual form submit (assuming you want that).

This is how I do this.

DateTime date_time_to_compare = DateTime.Now;
//Compare only date parts
context.YourObject.FirstOrDefault(r =>
                EntityFunctions.TruncateTime(r.date) == EntityFunctions.TruncateTime(date_to_compare));

You can make it even simplier, if you want to avoid extra structures.

service:
  mappings:
    key1: value1
    key2: value2

@Configuration
@EnableConfigurationProperties
public class ServiceConfigurationProperties {

  @Bean
  @ConfigurationProperties(prefix = "service.mappings")
  public Map<String, String> serviceMappings() {
    return new HashMap<>();
  }

}

And then use it as usual, for example with a constructor:

public class Foo {

  private final Map<String, String> serviceMappings;

  public Foo(Map<String, String> serviceMappings) {
    this.serviceMappings = serviceMappings;
  }

}

As far as I understand, the basic concept there is that you create small "services" that provide something useful to other systems and avoid building large systems that tend to do everything inside the system.

So you define a protocol which you will use for interaction (say, it might be SOAP web services) and let your "system-that-does-some-business-work" to interact with the small services to achieve your "big goal".

The join() was not helpful to me. see this sample in Kotlin:

    val timeInMillis = System.currentTimeMillis()
    ThreadUtils.startNewThread(Runnable {
        for (i in 1..5) {
            val t = Thread(Runnable {
                Thread.sleep(50)
                var a = i
                kotlin.io.println(Thread.currentThread().name + "|" + "a=$a")
                Thread.sleep(200)
                for (j in 1..5) {
                    a *= j
                    Thread.sleep(100)
                    kotlin.io.println(Thread.currentThread().name + "|" + "$a*$j=$a")
                }
                kotlin.io.println(Thread.currentThread().name + "|TaskDurationInMillis = " + (System.currentTimeMillis() - timeInMillis))
            })
            t.start()
        }
    })

The result:

Thread-5|a=5
Thread-1|a=1
Thread-3|a=3
Thread-2|a=2
Thread-4|a=4
Thread-2|2*1=2
Thread-3|3*1=3
Thread-1|1*1=1
Thread-5|5*1=5
Thread-4|4*1=4

Thread-2|12*3=12
Thread-4|24*3=24
Thread-4|96*4=96
Thread-2|48*4=48
Thread-5|120*4=120
Thread-1|24*4=24
Thread-3|72*4=72
Thread-5|600*5=600
Thread-4|480*5=480
Thread-3|360*5=360
Thread-1|120*5=120
Thread-2|240*5=240
Thread-1|TaskDurationInMillis = 765
Thread-3|TaskDurationInMillis = 765
Thread-4|TaskDurationInMillis = 765
Thread-5|TaskDurationInMillis = 765
Thread-2|TaskDurationInMillis = 765

Now let me use the join() for threads:

    val timeInMillis = System.currentTimeMillis()
    ThreadUtils.startNewThread(Runnable {
        for (i in 1..5) {
            val t = Thread(Runnable {
                Thread.sleep(50)
                var a = i
                kotlin.io.println(Thread.currentThread().name + "|" + "a=$a")
                Thread.sleep(200)
                for (j in 1..5) {
                    a *= j
                    Thread.sleep(100)
                    kotlin.io.println(Thread.currentThread().name + "|" + "$a*$j=$a")
                }
                kotlin.io.println(Thread.currentThread().name + "|TaskDurationInMillis = " + (System.currentTimeMillis() - timeInMillis))
            })
            t.start()
            t.join()
        }
    })

And the result:

Thread-1|a=1
Thread-1|1*1=1
Thread-1|2*2=2
Thread-1|6*3=6
Thread-1|24*4=24
Thread-1|120*5=120
Thread-1|TaskDurationInMillis = 815
Thread-2|a=2
Thread-2|2*1=2
Thread-2|4*2=4
Thread-2|12*3=12
Thread-2|48*4=48
Thread-2|240*5=240
Thread-2|TaskDurationInMillis = 1568
Thread-3|a=3
Thread-3|3*1=3
Thread-3|6*2=6
Thread-3|18*3=18
Thread-3|72*4=72
Thread-3|360*5=360
Thread-3|TaskDurationInMillis = 2323
Thread-4|a=4
Thread-4|4*1=4
Thread-4|8*2=8
Thread-4|24*3=24
Thread-4|96*4=96
Thread-4|480*5=480
Thread-4|TaskDurationInMillis = 3078
Thread-5|a=5
Thread-5|5*1=5
Thread-5|10*2=10
Thread-5|30*3=30
Thread-5|120*4=120
Thread-5|600*5=600
Thread-5|TaskDurationInMillis = 3833

As it's clear when we use the join:

1. The threads are running sequentially.
2. The first sample takes 765 Milliseconds while the second sample takes 3833 Milliseconds.

Our solution to prevent blocking other threads was creating an ArrayList:

val threads = ArrayList<Thread>()

Now when we want to start a new thread we most add it to the ArrayList:

addThreadToArray(
    ThreadUtils.startNewThread(Runnable {
        ...
    })
)

The addThreadToArray function:

@Synchronized
fun addThreadToArray(th: Thread) {
    threads.add(th)
}

The startNewThread funstion:

fun startNewThread(runnable: Runnable) : Thread {
    val th = Thread(runnable)
    th.isDaemon = false
    th.priority = Thread.MAX_PRIORITY
    th.start()
    return th
}

Check the completion of the threads as below everywhere it's needed:

val notAliveThreads = ArrayList<Thread>()
for (t in threads)
    if (!t.isAlive)
        notAliveThreads.add(t)
threads.removeAll(notAliveThreads)
if (threads.size == 0){
    // The size is 0 -> there is no alive threads.
}

It needs to be a jQuery element to use .addClass(), so it needs to be wrapped in $() like this:

function addClassByClick(button){
  $(button).addClass("active")
}

A better overall solution would be unobtrusive script, for example:

<asp:Button ID="Button" runat="server" class="clickable"/>

Then in jquery:

$(function() {                       //run when the DOM is ready
  $(".clickable").click(function() {  //use a class, since your ID gets mangled
    $(this).addClass("active");      //add the class to the clicked element
  });
});

I needed to know how to loop over enum values (was testing lots of permutations of several enums) and I found this to work well:

export enum Environment {
    Prod = "http://asdf.com",
    Stage = "http://asdf1234.com",
    Test = "http://asdfasdf.example.com"
}

Object.keys(Environment).forEach((environmentKeyValue) => {
    const env = Environment[environmentKeyValue as keyof typeof Environment]
    // env is now equivalent to Environment.Prod, Environment.Stage, or Environment.Test
}

You need to run Set-ExecutionPolicy:

Set-ExecutionPolicy Unrestricted <-- Will allow unsigned PowerShell scripts to run.

Set-ExecutionPolicy Restricted <-- Will not allow unsigned PowerShell scripts to run.

Set-ExecutionPolicy RemoteSigned <-- Will allow only remotely signed PowerShell scripts to run.

My program seems to suffer from linear access to dictionaries, its run-time grows exponentially even though the algorithm is quadratic.

I use a dictionary to memoize values. That seems to be a bottleneck.

This is evidence of a bug in your memoization method.

After struggling with this issue too many times I found a very elegant solution in HTML 5. In HTML 5 you should not close several (li,p,etc) tags; the ambition to become XML is forever gone. For example, the preferred way to do a list is:

<ul>
   <li>
       <a ...>...</a>
   <li>
       <a ...>...</a>
</ul>

Browsers MUST close the LI and they must do this without introducing whitespace, solving this problem. If you still have the XML mindset it feels wrong but once you get over that it saves many a nightmare. And this is not a hack since it relies on the wording of the HTML 5 spec. Better, since not closing tags is pervasive I expect no compatibility issues (not tested though). Bonus is that HTML formatters handle this well.

A little worked out example: http://cssdesk.com/Ls7fK

Well it depends on the memory allocator implementation and the OS.

Under windows for example a process can ask for a page or more of RAM. The OS then assigns those pages to the process. This is not, however, memory allocated to your application. The CRT memory allocator will mark the memory as a contiguous "available" block. The CRT memory allocator will then run through the list of free blocks and find the smallest possible block that it can use. It will then take as much of that block as it needs and add it to an "allocated" list. Attached to the head of the actual memory allocation will be a header. This header will contain various bit of information (it could, for example, contain the next and previous allocated blocks to form a linked list. It will most probably contain the size of the allocation).

Free will then remove the header and add it back to the free memory list. If it forms a larger block with the surrounding free blocks these will be added together to give a larger block. If a whole page is now free the allocator will, most likely, return the page to the OS.

It is not a simple problem. The OS allocator portion is completely out of your control. I recommend you read through something like Doug Lea's Malloc (DLMalloc) to get an understanding of how a fairly fast allocator will work.

Edit: Your crash will be caused by the fact that by writing larger than the allocation you have overwritten the next memory header. This way when it frees it gets very confused as to what exactly it is free'ing and how to merge into the following block. This may not always cause a crash straight away on the free. It may cause a crash later on. In general avoid memory overwrites!

This is also one possibility: Make Sure that you should write this code before the route in your app.js(or index.js) file.

app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());

Simply disable default browser behaviour using preventDefault and pass the event within your HTML.

<a href=/foo onclick= yes_js_login(event)>Lorem ipsum</a>

yes_js_login = function(e) {
  e.preventDefault();
}

Build.SERIAL can be empty or sometimes return a different value (proof 1, proof 2) than what you can see in your device's settings.

If you want a more complete and robust solution, I've compiled every possible solution I could found in a single gist. Here's a simplified version of it :

public static String getSerialNumber() {
    String serialNumber;

    try {
        Class<?> c = Class.forName("android.os.SystemProperties");
        Method get = c.getMethod("get", String.class);

        serialNumber = (String) get.invoke(c, "gsm.sn1");
        if (serialNumber.equals(""))
            serialNumber = (String) get.invoke(c, "ril.serialnumber");
        if (serialNumber.equals(""))
            serialNumber = (String) get.invoke(c, "ro.serialno");
        if (serialNumber.equals(""))
            serialNumber = (String) get.invoke(c, "sys.serialnumber");
        if (serialNumber.equals(""))
            serialNumber = Build.SERIAL;

        // If none of the methods above worked
        if (serialNumber.equals(""))
            serialNumber = null;
    } catch (Exception e) {
        e.printStackTrace();
        serialNumber = null;
    }

    return serialNumber;
}

I try to update the gist regularly whenever I can test on a new device or Android version. Contributions are welcome too.

This is a very straightforward solution that I came up with after following conca's link and looking at background size. It blows the image up and then fits it centered into the outer container w/o scaling it.

<style>
#cropcontainer
{
  width:  100%; 
  height: 100%; 
  background-size: 140%;
  background-position: center;
  background-repeat: no-repeat;
}
</style>

<div id="cropcontainer" style="background-image: url(yoururl); />

I don't know what your exact problem is, but if you're receiving XML and want to return JSON (or something) you could also look at JAX-B. This is a standard for marshalling/unmarshalling Java POJO's to XML and/or Json. There are multiple libraries that implement JAX-B, for example Apache's CXF.

In my case, I have just install express-status-monitor to get rid of this error

here are the settings

install express-status-monitor
npm i express-status-monitor --save
const expressStatusMonitor = require('express-status-monitor');
app.use(expressStatusMonitor({
    websocket: io,
    port: app.get('port')
}));

You should place Scanner input = new Scanner (System.in); into the main method rather than creating the input object outside.

You could do it with the requests module as well:

url = 'http://winterolympicsmedals.com/medals.csv'
r = requests.get(url)
text = r.iter_lines()
reader = csv.reader(text, delimiter=',')

Simple solution would be as below. This is improvement of solution from vale.

private void dgMapTable_SelectionChanged(object sender, EventArgs e) 
{
    int active_map=0;
    if(dgMapTable.SelectedRows.Count>0)
        active_map = dgMapTable.SelectedRows[0].Index;
    // User code if required Process_ROW(active_map);
}

Note for other reader, for above code to work FullRowSelect selection mode for datagridview should be used. You may extend this to give message if more than two rows selected.

Try:

CREATE TABLE test (
  ID INTEGER,
  NAME VARCHAR (50),
  VALUE INTEGER
);

INSERT INTO test VALUES (1, 'A', 4);
INSERT INTO test VALUES (1, 'A', 5);
INSERT INTO test VALUES (1, 'B', 8);
INSERT INTO test VALUES (2, 'C', 9);

SELECT ID, GROUP_CONCAT(NAME ORDER BY NAME ASC SEPARATOR ',')
FROM (
  SELECT ID, CONCAT(NAME, ':', GROUP_CONCAT(VALUE ORDER BY VALUE ASC SEPARATOR ',')) AS NAME
  FROM test
  GROUP BY ID, NAME
) AS A
GROUP BY ID;

SQL Fiddle: http://sqlfiddle.com/#!2/b5abe/9/0

For users of SQL 2000, the actual command that will provide this information is:

select c.text
from sysobjects     o
join syscomments    c on c.id = o.id
where o.name = '<view_name_here>'
  and o.type      = 'V'

Two ways:

1. Implement ActionListener in your class, then use jBtnSelection.addActionListener(this); Later, you'll have to define a menthod, public void actionPerformed(ActionEvent e). However, doing this for multiple buttons can be confusing, because the actionPerformed method will have to check the source of each event (e.getSource()) to see which button it came from.

2. Use anonymous inner classes:

jBtnSelection.addActionListener(new ActionListener() { 
  public void actionPerformed(ActionEvent e) { 
    selectionButtonPressed();
  } 
} );

Later, you'll have to define selectionButtonPressed(). This works better when you have multiple buttons, because your calls to individual methods for handling the actions are right next to the definition of the button.

The second method also allows you to call the selection method directly. In this case, you could call selectionButtonPressed() if some other action happens, too - like, when a timer goes off or something (but in this case, your method would be named something different, maybe selectionChanged()).

Approach 1

While converting a gray scale image to a binary image, we usually use cv2.threshold() and set a threshold value manually. Sometimes to get a decent result we opt for Otsu's binarization.

I have a small hack I came across while reading some blog posts.

1. Convert your color (RGB) image to gray scale.
2. Obtain the median of the gray scale image.
3. Choose a threshold value either 33% above the median

Why 33%?

This is because 33% works for most of the images/data-set.

You can also work out the same approach by replacing median with the mean.

Approach 2

Another approach would be to take an x number of standard deviations (std) from the mean, either on the positive or negative side; and set a threshold. So it could be one of the following:

• th1 = mean - (x * std)
• th2 = mean + (x * std)

Note: Before applying threshold it is advisable to enhance the contrast of the gray scale image locally (See CLAHE).

This is the function that I generally use in my code to prepend zeros to a number or string.

The inputs are the string or number (str), and the desired length of the output (len).

var PrependZeros = function (str, len) {
    if(typeof str === 'number' || Number(str)){
    str = str.toString();
    return (len - str.length > 0) ? new Array(len + 1 - str.length).join('0') + str: str;
}
else{
    for(var i = 0,spl = str.split(' '); i < spl.length; spl[i] = (Number(spl[i])&& spl[i].length < len)?PrependZeros(spl[i],len):spl[i],str = (i == spl.length -1)?spl.join(' '):str,i++);
    return str;
}

};

Examples:

PrependZeros('MR 3',3);    // MR 003
PrependZeros('MR 23',3);   // MR 023
PrependZeros('MR 123',3);  // MR 123
PrependZeros('foo bar 23',3);  // foo bar 023

This is not necessarily a VBA task - This specific task is easiest sollowed with Auto filter.

1.Insert Auto filter (In Excel 2010 click on home-> (Editing) Sort & Filter -> Filter)
2. Filter on the 'Websites' column
3. Mark the 'none' and delete them
4. Clear filter

Yeah, when ASP.NET web.config gets updated, the whole application gets restarted which means the web.config gets reloaded.

//checking duplicate elements in an array
var arr=[1,3,4,6,8,9,1,3,4,7];
var hp=new Map();
console.log(arr.sort());
var freq=0;
for(var i=1;i<arr.length;i++){
// console.log(arr[i-1]+" "+arr[i]);
if(arr[i]==arr[i-1]){
freq++;

}
else{
hp.set(arr[i-1],freq+1);
freq=0;
}
}
console.log(hp);

One wrinkle I ran into (that isn't covered in other answers):

Suppose you have these namespaces:

• Something.Other
• Parent.Something.Other

When you use using Something.Other outside of a namespace Parent, it refers to the first one (Something.Other).

However if you use it inside of that namespace declaration, it refers to the second one (Parent.Something.Other)!

There is a simple solution: add the "global::" prefix: docs

namespace Parent
{
   using global::Something.Other;
   // etc
}

Optional arguments only work at the end of a function call. There is no way to specify a value for $y in your function without also specifying $x. Some languages support this via named parameters (VB/C# for example), but not PHP.

You can emulate this if you use an associative array for parameters instead of arguments -- i.e.

function foo(array $args = array()) {
    $x = !isset($args['x']) ? 'default x value' : $args['x'];
    $y = !isset($args['y']) ? 'default y value' : $args['y'];

    ...
}

Then call the function like so:

foo(array('y' => 'my value'));

Change the query to

"INSERT INTO Mem_Basic(Mem_Na,Mem_Occ) VALUES(@na,@occ); SELECT SCOPE_IDENTITY()"

This will return the last inserted ID which you can then get with ExecuteScalar

You can also use dirname in dirname to get to where you want to be.

Example of usage:

For Joomla, modules will always be installed in /public_html/modules/mod_modulename/

So, from within a file within the module's folder, to get to the Joomla install-root on any server , I could use: $path = dirname(dirname(dirname(__FILE__)));

The same goes for Wordpress, where plugins are always in wp-content/plugins/

Hope this helps someone.

Try this. This script gets current logged in user's name & home directory:

On Error Resume Next

Dim objShell, strTemp
Set objShell = WScript.CreateObject("WScript.Shell")

strTemp = "HKEY_CURRENT_USER\Volatile Environment\USERNAME"
WScript.Echo "Logged in User: " & objShell.RegRead(strTemp) 

strTemp = "HKEY_CURRENT_USER\Volatile Environment\USERPROFILE"
WScript.Echo "User Home: " & objShell.RegRead(strTemp) 

you can use implicit casting AddWithValue

cmd.Parameters.AddWithValue("@param1", klantId);
cmd.Parameters.AddWithValue("@param2", klantNaam);
cmd.Parameters.AddWithValue("@param3", klantVoornaam);

sample code,

using (SqlConnection conn = new SqlConnection("connectionString")) 
{
    using (SqlCommand cmd = new SqlCommand()) 
    { 
        cmd.Connection = conn;
        cmd.CommandType = CommandType.Text;
        cmd.CommandText = @"INSERT INTO klant(klant_id,naam,voornaam) 
                            VALUES(@param1,@param2,@param3)";  

        cmd.Parameters.AddWithValue("@param1", klantId);  
        cmd.Parameters.AddWithValue("@param2", klantNaam);  
        cmd.Parameters.AddWithValue("@param3", klantVoornaam);  

        try
        {
            conn.Open();
            cmd.ExecuteNonQuery(); 
        }
        catch(SqlException e)
        {
            MessgeBox.Show(e.Message.ToString(), "Error Message");
        }

    } 
}

This can happen if you forget to return a value from a function: it then returns None. Look at all places where you are assigning to that variable, and see if one of them is a function call where the function lacks a return statement.

Using ES6 modules (initially proposed by @d13) works well for me. It doesn't mimic private properties perfectly, but at least you can be confident that properties that should be private won't leak outside of your class. Here's an example:

something.js

let _message = null;
const _greet = name => {
  console.log('Hello ' + name);
};

export default class Something {
  constructor(message) {
    _message = message;
  }

  say() {
    console.log(_message);
    _greet('Bob');
  }
};

Then the consuming code can look like this:

import Something from './something.js';

const something = new Something('Sunny day!');
something.say();
something._message; // undefined
something._greet(); // exception

Update (Important):

As @DanyalAytekin outlined in the comments, these private properties are static, so therefore global in scope. They will work well when working with Singletons, but care must be taken for Transient objects. Extending the example above:

import Something from './something.js';
import Something2 from './something.js';

const a = new Something('a');
a.say(); // a

const b = new Something('b');
b.say(); // b

const c = new Something2('c');
c.say(); // c

a.say(); // c
b.say(); // c
c.say(); // c

I have seen most of the people saying explicit parent to child casting is not possible, that actually is not true. Let's take a revised start and try proving it by examples.

As we know in .net all castings have two broad categories.

1. For Value type
2. For Reference type (in your case its reference type)

Reference type has further three main situational cases in which any scenario can lie.

Child to Parent (Implicit casting - Always successful)

Case 1. Child to any direct or indirect parent

Employee e = new Employee();
Person p = (Person)e; //Allowed

Parent to Child (Explicit casting - Can be successful)

Case 2. Parent variable holding parent object (Not allowed)

Person p = new Person();  // p is true Person object
Employee e = (Employee)p; //Runtime err : InvalidCastException <-------- Yours issue

Case 3. Parent variable holding child object (Always Successful)

Note: Because objects has polymorphic nature, it is possible for a variable of a parent class type to hold a child type.

Person p = new Employee(); // p actually is Employee
Employee e = (Employee)p; // Casting allowed

Conclusion : After reading above all, hope it will make sense now like how parent to child conversion is possible(Case 3).

Answer To The Question :

Your answer is in case 2.Where you can see such casting is not allowed by OOP and you are trying to violate one of OOP's basic rule.So always choose safe path.

Further more, to avoid such exceptional situations .net has recommended using is/as operators those will help you to take informed decisions and provide safe casting.

If you are that particular to pass elements to viewmodel You can use

 CommandParameter="{Binding ElementName=ManualParcelScanScreen}"

Assuming your field is a date type (or similar):

SELECT DATE_ADD(`your_field_name`, INTERVAL 2 DAY) 
FROM `table_name`;

With the example you've provided it could look like this:

UPDATE classes 
SET `date` = DATE_ADD(`date` , INTERVAL 2 DAY)
WHERE `id` = 161;

This approach works with datetime , too.

you can use a diferent class:

like

.clase
{
text-decoration-color: none;
color: #682864;
text-decoration: none;

}
.clase2:hover
{
color: white;
text-decoration: none;
}

 <a href="#" class="clase2 clase"> link que no tiene subrayado ni color standar</a>

It sounds like you want to convert the rownames to a proper column of the data.frame. eg:

# add the rownames as a proper column
myDF <- cbind(Row.Names = rownames(myDF), myDF)
myDF

#           Row.Names id val vr2
# row_one     row_one  A   1  23
# row_two     row_two  A   2  24
# row_three row_three  B   3  25
# row_four   row_four  C   4  26

If you want to then remove the original rownames:

rownames(myDF) <- NULL
myDF
#   Row.Names id val vr2
# 1   row_one  A   1  23
# 2   row_two  A   2  24
# 3 row_three  B   3  25
# 4  row_four  C   4  26

Alternatively, if all of your data is of the same class (ie, all numeric, or all string), you can convert to Matrix and name the dimnames

myMat <- as.matrix(myDF)
names(dimnames(myMat)) <- c("Names.of.Rows", "")
myMat

# Names.of.Rows id  val vr2 
#   row_one   "A" "1" "23"
#   row_two   "A" "2" "24"
#   row_three "B" "3" "25"
#   row_four  "C" "4" "26"

Identifiers (including column names) that are not double-quoted are folded to lower case in PostgreSQL. Column names that were created with double-quotes and thereby retained upper-case letters (and/or other syntax violations) have to be double-quoted for the rest of their life:

"first_Name"

Values (string literals / constants) are enclosed in single quotes:

'xyz'

So, yes, PostgreSQL column names are case-sensitive (when double-quoted):

SELECT * FROM persons WHERE "first_Name" = 'xyz';

Read the manual on identifiers here.

My standing advice is to use legal, lower-case names exclusively so double-quoting is not needed.

I have a three column table with just over 6 Billion rows in SQL Server 2008 R2.

We query it every day to create minute-by-minute system analysis charts for our customers. I have not noticed any database performance hits (though the fact that it grows ~1 GB every day does make managing backups a bit more involved than I would like).

Update July 2016

We made it to ~24.5 billion rows before backups became large enough for us to decide to truncate records older than two years (~700 GB stored in multiple backups, including on expensive tapes). It's worth noting that performance was not a significant motivator in this decision (i.e., it was still working great).

For anyone who finds themselves trying to delete 20 billion rows from SQL Server, I highly recommend this article. Relevant code in case the link dies (read the article for a full explanation):

If you plan on storing this much data in a single table: don't. I highly recommend you consider table partitioning (either manually or with the built-in features if you're running Enterprise edition). This makes dropping old data as easy as truncating a table once a (week/month/etc.). If you don't have Enterprise (which we don't), you can simply write a script which runs once a month, drops tables older than 2 years, creates next month's table, and regenerates a dynamic view that joins all of the partition tables together for easy querying. Obviously "once a month" and "older than 2 years" should be defined by you based on what makes sense for your use-case. Deleting directly from a table with tens of billions of rows of data will a) take a HUGE amount of time and b) fill up the transaction log hundreds or thousands of times over.

If you want to create a small dots, just use icon from font awesome.

In answer to your first question, there's no parameter substitution because you've put the delimiter in quotes - the bash manual says:

The format of here-documents is:

      <<[-]word
              here-document
      delimiter

No parameter expansion, command substitution, arithmetic expansion, or pathname expansion is performed on word. If any characters in word are quoted, the delimiter is the result of quote removal on word, and the lines in the here-document are not expanded. If word is unquoted, all lines of the here-document are subjected to parameter expansion, command substitution, and arithmetic expansion. [...]

If you change your first example to use <<EOF instead of << "EOF" you'll find that it works.

In your second example, the shell invokes sudo only with the parameter cat, and the redirection applies to the output of sudo cat as the original user. It'll work if you try:

sudo sh -c "cat > /path/to/outfile" <<EOT
my text...
EOT

I got the same error message for two separate reasons, so you can add them to your debugging checklist:

Context: Xcode 6.4, iOS:8.4. I was adding a toolbar with custom UIBarButtons to load with the UIKeyboardTypeNumberPad (Swift: UIKeyboardType.numberPad) , namely "Done" and "+/-". I had this problem when:

1. My UIToolbar was declared as a property, but I had forgotten to explicitly alloc/init it.

2. I had left off the last line, [myCustomToolbar sizeToFit];, which sounds like it's the same family as Holden's answer (my code here: https://stackoverflow.com/a/32016397/4898050).

Good luck

Another option is to pass the single quote as an awk variable:

awk -v q=\' 'BEGIN {FS=" ";} {printf "%s%s%s ", q, $1, q}'

Simpler example with string concatenation:

# Prints 'test me', *including* the single quotes.
$ awk -v q=\' '{print q $0 q }' <<<'test me'
'test me'

Instead of:

void addStudent(person)
{
    return;
}

try this:

void addStudent(student person)
{
    return;
}

Since you have already declared a structure called 'student' you don't necessarily have to specify so in the function implementation as in:

void addStudent(struct student person)
{
    return;
}

Another reason could be that you have changed the machine from which you're submitting the app. Or the user account on the machine. The new machine may lack the private key and/or certificate for the App Store. Although a certificate with the correct name is displayed in Xcode.

In this case, go to https://developer.apple.com -> certificates, use the plus sign (+) to add a new certificate (distribution), and follow the steps to request a certificate for the private key on your current machine. After installing the certificate, authentication may work.

If you cannot set the width, then that means the width will change as the text gets bold. There is no way to avoid this, except by compromises such as modifying the padding/margins for each state.

The Android Gradle plugin is still in beta and this may simply be a bug. For me, setting ANDROID_HOME works, but we may be on different versions (please try again with the most recent version and let me know if it works or not).

It's also worth setting the environment variable ANDROID_SDK as well as ANDROID_HOME.

I have seen issues with this on some machines, so we do create local.properties in those cases - I have also noticed that the latest version of Android Studio will create this file for you and fill in the sdk.dir property.

Note that you shouldn't check local.properties into version control, we have added it to our gitignore so that it doesn't interfere with porting the code across systems which you rightfully identified as a potential problem.

If you want to apply styles only to an element which is its parents' first child, is it better to use :first-child pseudo-class

.social:first-child{
    border-bottom: dotted 1px #6d6d6d;
    padding-top: 0;
}
.social{
    border: 0;
    width: 330px;
    height: 75px;
    float: right;
    text-align: left;
    padding: 10px 0;
}

Then, the rule .social has both common styles and the last element's styles.

And .social:first-child overrides them with first element's styles.

You could also use :last-child selector, but :first-childis more supported by old browsers: see https://developer.mozilla.org/en-US/docs/CSS/:first-child#Browser_compatibility and https://developer.mozilla.org/es/docs/CSS/:last-child#Browser_compatibility.

You can make an Embedded class, which contains your two keys, and then have a reference to that class as EmbeddedId in your Entity.

You would need the @EmbeddedId and @Embeddable annotations.

@Entity
public class YourEntity {
    @EmbeddedId
    private MyKey myKey;

    @Column(name = "ColumnA")
    private String columnA;

    /** Your getters and setters **/
}

@Embeddable
public class MyKey implements Serializable {

    @Column(name = "Id", nullable = false)
    private int id;

    @Column(name = "Version", nullable = false)
    private int version;

    /** getters and setters **/
}

Another way to achieve this task is to use @IdClass annotation, and place both your id in that IdClass. Now you can use normal @Id annotation on both the attributes

@Entity
@IdClass(MyKey.class)
public class YourEntity {
   @Id
   private int id;
   @Id
   private int version;

}

public class MyKey implements Serializable {
   private int id;
   private int version;
}

Let's start with this simple state diagram:

We have:

• 4 states (Inactive, Active, Paused, and Exited)
• 5 types of state transitions (Begin Command, End Command, Pause Command, Resume Command, Exit Command).

You can convert this to C# in a handful of ways, such as performing a switch statement on the current state and command, or looking up transitions in a transition table. For this simple state machine, I prefer a transition table, which is very easy to represent using a Dictionary:

using System;
using System.Collections.Generic;

namespace Juliet
{
    public enum ProcessState
    {
        Inactive,
        Active,
        Paused,
        Terminated
    }

    public enum Command
    {
        Begin,
        End,
        Pause,
        Resume,
        Exit
    }

    public class Process
    {
        class StateTransition
        {
            readonly ProcessState CurrentState;
            readonly Command Command;

            public StateTransition(ProcessState currentState, Command command)
            {
                CurrentState = currentState;
                Command = command;
            }

            public override int GetHashCode()
            {
                return 17 + 31 * CurrentState.GetHashCode() + 31 * Command.GetHashCode();
            }

            public override bool Equals(object obj)
            {
                StateTransition other = obj as StateTransition;
                return other != null && this.CurrentState == other.CurrentState && this.Command == other.Command;
            }
        }

        Dictionary<StateTransition, ProcessState> transitions;
        public ProcessState CurrentState { get; private set; }

        public Process()
        {
            CurrentState = ProcessState.Inactive;
            transitions = new Dictionary<StateTransition, ProcessState>
            {
                { new StateTransition(ProcessState.Inactive, Command.Exit), ProcessState.Terminated },
                { new StateTransition(ProcessState.Inactive, Command.Begin), ProcessState.Active },
                { new StateTransition(ProcessState.Active, Command.End), ProcessState.Inactive },
                { new StateTransition(ProcessState.Active, Command.Pause), ProcessState.Paused },
                { new StateTransition(ProcessState.Paused, Command.End), ProcessState.Inactive },
                { new StateTransition(ProcessState.Paused, Command.Resume), ProcessState.Active }
            };
        }

        public ProcessState GetNext(Command command)
        {
            StateTransition transition = new StateTransition(CurrentState, command);
            ProcessState nextState;
            if (!transitions.TryGetValue(transition, out nextState))
                throw new Exception("Invalid transition: " + CurrentState + " -> " + command);
            return nextState;
        }

        public ProcessState MoveNext(Command command)
        {
            CurrentState = GetNext(command);
            return CurrentState;
        }
    }


    public class Program
    {
        static void Main(string[] args)
        {
            Process p = new Process();
            Console.WriteLine("Current State = " + p.CurrentState);
            Console.WriteLine("Command.Begin: Current State = " + p.MoveNext(Command.Begin));
            Console.WriteLine("Command.Pause: Current State = " + p.MoveNext(Command.Pause));
            Console.WriteLine("Command.End: Current State = " + p.MoveNext(Command.End));
            Console.WriteLine("Command.Exit: Current State = " + p.MoveNext(Command.Exit));
            Console.ReadLine();
        }
    }
}

As a matter of personal preference, I like to design my state machines with a GetNext function to return the next state deterministically, and a MoveNext function to mutate the state machine.

For quick RPM building, check out Togo:

https://github.com/genereese/togo-rpm

The project has a Quick-Start guide and I was able to create a basic RPM in less than 3 minutes.

Example using the data provided in the original question:

1) Create the project directory using the script:

$ togo project create foobar; cd foobar

2) Make your desired directory structure under ./root and copy your files into it:

$ mkdir -p root/etc; cp /path/to/foobar.conf root/etc/
$ mkdir -p root/usr/bin; cp /path/to/foobar root/usr/bin/

3) Exclude system-owned directories from your RPM's ownership:

$ togo file exclude root/etc root/usr/bin

4) (OPTIONAL) Modify the generated spec to change your package description/dependencies/version/whatever, etc.:

$ vi spec/header

5) Build the RPM:

$ togo build package

-and your RPM is spit out into the ./rpms directory.

Using Linq to find the object you can do:

var obj = myList.FirstOrDefault(x => x.MyProperty == myValue);
if (obj != null) obj.OtherProperty = newValue;

But in this case you might want to save the List into a Dictionary and use this instead:

// ... define after getting the List/Enumerable/whatever
var dict = myList.ToDictionary(x => x.MyProperty);
// ... somewhere in code
MyObject found;
if (dict.TryGetValue(myValue, out found)) found.OtherProperty = newValue;

You can use the ApplicationContextAware class that can provide the application context.

public class ApplicationContextProvider implements ApplicationContextAware {

    private static ApplicationContext ctx = null;

    public static ApplicationContext getApplicationContext() {
        return ctx;
    }

    @Override
    public void setApplicationContext(final ApplicationContext ctx) throws BeansException {
        ApplicationContextProvider.ctx = ctx;
    }

    /**
     * Tries to autowire the specified instance of the class if one of the specified
     * beans which need to be autowired are null.
     *
     * @param classToAutowire        the instance of the class which holds @Autowire
     *                               annotations
     * @param beansToAutowireInClass the beans which have the @Autowire annotation
     *                               in the specified {#classToAutowire}
     */
    public static void autowire(Object classToAutowire, Object... beansToAutowireInClass) {
        for (Object bean : beansToAutowireInClass) {
            if (bean == null) {
                ctx.getAutowireCapableBeanFactory().autowireBean(classToAutowire);
            }
        }
    }

}

As detailed by this answer on this page, a status code of 0 means the request failed for some reason, and a javascript library interpreted the fail as a status code of 0.

To test this you can do either of the following:

1) Use this chrome extension, Requestly to redirect your url from the https version of your url to the http version, as this will cause a mixed content security error, and ultimately generate a status code of 0. The advantage of this approach is that you don't have to change your app at all, and you can simply "rewrite" your url using this extension.

2) Change the code of your app to optionally make your endpoint redirect to the http version of your url instead of the https version (or vice versa). If you do this, the request will fail with status code 0.

I bumped into this problem lately with Windows 10 from another direction, and found the answer from @JonSkeet very helpful in solving my problem.

I also did som further research with a test form and found that when the the current culture was set to "no" or "nb-NO" at runtime (Thread.CurrentThread.CurrentCulture = new CultureInfo("no");), the ToString("yyyy-MM-dd HH:mm:ss") call responded differently in Windows 7 and Windows 10. It returned what I expected in Windows 7 and HH.mm.ss in Windows 10!

I think this is a bit scary! Since I believed that a culture was a culture in any Windows version at least.

Go to the Eclipse base folder ? open eclipse.ini ? you will find the below line at line no 4:

plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20150204-1316 plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.200.v20120913-144807

As you can see, line 1 is of 64-bit Eclipse. It contains x86_64 and line 2 is of 32-bit Eclipse. It contains x_86.

For 32-bit Eclipse only x86 will be present and for 64-bit Eclipse x86_64 will be present.

Disadvantage of second approach is big repository with created loggers. This loggers do the same if root is defined and class loggers are not defined. Standard scenario on production system is using few loggers dedicated to group of class. Sorry for my English.

Take a look on your running processes, it seems like your current Tomcat instance did not stop. It's still running and NetBeans tries to start a second Tomcat-instance. Thats the reason for your exception, you just have to stop the first instance, or deploy you code on the current running one

In Jenkins:

echo '<your-password>' | sudo -S command

Eg:-

echo '******' | sudo -S service nginx restart

You can use Mask Password Plugin to hide your password

The commented out version is the more correct way to do this.

If you use the == operator on strings, you're comparing the strings' addresses (where they're allocated in memory) rather than the values of the strings. This is very occasional useful (it indicates you have the exact same string object), but 99% of the time you want to compare the values, which you do like so:

if([myT isEqualToString:@"10"] || [myT isEqualToString:@"11"] || [myT isEqualToString:@"12"])

 <Button android:id="@+id/imeageTextBtn" 
        android:layout_width="240dip"
        android:layout_height="wrap_content"
        android:text="Side Icon With Text Button"
        android:textSize="20sp"
        android:drawableLeft="@drawable/left_side_icon"         
        />   

If you use GUID as primary key and create clustered index then I suggest use the default of NEWSEQUENTIALID() value for it.

In fact, your data is not well design. You'd better use something like :

$scope.steps = [
    {stepName: "companyName", isComplete: true},
    {stepName: "businessType", isComplete: true},
    {stepName: "physicalAddress", isComplete: true}
];

Then it is easy to do what you want :

<div ng-repeat="step in steps">
 Step {{step.stepName}} status : {{step.isComplet}}
</div>

Example: http://jsfiddle.net/rX7ba/

You can just use the keywork value to accomplish this.

public int Hour {
    get{
        // Do some logic if you want
        //return some custom stuff based on logic

        // or just return the value
        return value;
    }; set { 
        // Do some logic stuff 
        if(value < MINVALUE){
            this.Hour = 0;
        } else {
            // Or just set the value
            this.Hour = value;
        }

The link posted by Jose has been updated and pylab now has a tight_layout() function that does this automatically (in matplotlib version 1.1.0).

You can get the device ip address by this way:

adb shell ip route > addrs.txt
#Case 1:Nexus 7
#192.168.88.0/23 dev wlan0  proto kernel  scope link  src 192.168.89.48

#Case 2: Smartsian T1,Huawei C8813
#default via 192.168.88.1 dev eth0  metric 30
#8.8.8.8 via 192.168.88.1 dev eth0  metric 30
#114.114.114.114 via 192.168.88.1 dev eth0  metric 30
#192.168.88.0/23 dev eth0  proto kernel  scope link  src 192.168.89.152 metric 30
#192.168.88.1 dev eth0  scope link  metric 30

ip_addrs=$(awk {'if( NF >=9){print $9;}'} addrs.txt)

echo "the device ip address is $ip_addrs"

Use the following:

driver.findElement(By.id("id")).sendKeys(Keys.chord(Keys.CONTROL, "a", Keys.DELETE), "Your Value");

I'm not sure if your problem is being caused by the same reason that mine was, but I too was experiencing a hanging "npm install" and was able to fix it.

In my case, I wanted to install typescript locally in the project:

npm i typescript --save-dev

For some reason this was conflicting with a global install of typescript that I had, and the shell was just hanging forever instead of finishing or erroring...

I fixing it by first removing the globally installed typescript with the -g global flag:

npm uninstall typescript -g

After doing this the first command worked!

C++11 has some portable timer stuff. Check out sleep_for.

Even though is not the fastest choice, if performance is not an issue you can use:

sum(~np.isnan(data)).

Performance:

In [7]: %timeit data.size - np.count_nonzero(np.isnan(data))
10 loops, best of 3: 67.5 ms per loop

In [8]: %timeit sum(~np.isnan(data))
10 loops, best of 3: 154 ms per loop

In [9]: %timeit np.sum(~np.isnan(data))
10 loops, best of 3: 140 ms per loop

You can use the cache dir using context.getCacheDir().

File temp=File.createTempFile("prefix","suffix",context.getCacheDir());

If you need user's SID and browse remote HKEY_USERS folder, you can follow this script :

<# Replace following domain.name with yours and userAccountName with remote username #>
$userLogin = New-Object System.Security.Principal.NTAccount(“domain.name“,”userAccountName“)
$userSID = $userLogin.Translate([System.Security.Principal.SecurityIdentifier])

<# We will open HKEY_USERS and with accurate user’s SID from remoteComputer #>
$remoteRegistry = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey(‘Users’,”remoteComputer“)

<# We will then retrieve LocalName value from Control Panel / International subkeys #>

$key = $userSID.value+”\Control Panel\International”
$openKey = $remoteRegistry.OpenSubKey($key)

<# We can now retrieve any values #>

$localName = $openKey.GetValue(‘LocaleName’)

Try list(newdict.keys()).

This will convert the dict_keys object to a list.

On the other hand, you should ask yourself whether or not it matters. The Pythonic way to code is to assume duck typing (if it looks like a duck and it quacks like a duck, it's a duck). The dict_keys object will act like a list for most purposes. For instance:

for key in newdict.keys():
  print(key)

Obviously, insertion operators may not work, but that doesn't make much sense for a list of dictionary keys anyway.

I'm using android:scaleType="fitCenter" with satisfaction.

You could call:

getContentPane().setBackground(Color.black);

Or add a JPanel to the JFrame your using. Then add your components to the JPanel. This will allow you to call

setBackground(Color.black);

on the JPanel to set the background color.

You could use the GetSize function to get those information, cv.GetSize(im) would return a tuple with the width and height of the image. You can also use im.depth and img.nChan to get some more information.

And to resize an image, I would use a slightly different process, with another image instead of a matrix. It is better to try to work with the same type of data:

size = cv.GetSize(im)
thumbnail = cv.CreateImage( ( size[0] / 10, size[1] / 10), im.depth, im.nChannels)
cv.Resize(im, thumbnail)

Hope this helps ;)

Often this question is asked in the context of Ron de Bruin's RangeToHTML function, which creates an HTML PublishObject from an Excel.Range, extracts that via FSO, and inserts the resulting stream HTML in to the email's HTMLBody. In doing so, this removes the default signature (the RangeToHTML function has a helper function GetBoiler which attempts to insert the default signature).

Unfortunately, the poorly-documented Application.CommandBars method is not available via Outlook:

wdDoc.Application.CommandBars.ExecuteMso "PasteExcelTableSourceFormatting"

It will raise a runtime 6158:

But we can still leverage the Word.Document which is accessible via the MailItem.GetInspector method, we can do something like this to copy & paste the selection from Excel to the Outlook email body, preserving your default signature (if there is one).

Dim rng as Range
Set rng = Range("A1:F10") 'Modify as needed

With OutMail
    .To = "[email protected]"
    .BCC = ""
    .Subject = "Subject"
    .Display
    Dim wdDoc As Object     '## Word.Document
    Dim wdRange As Object   '## Word.Range
    Set wdDoc = OutMail.GetInspector.WordEditor
    Set wdRange = wdDoc.Range(0, 0)
    wdRange.InsertAfter vbCrLf & vbCrLf
    'Copy the range in-place
    rng.Copy
    wdRange.Paste
End With

Note that in some cases this may not perfectly preserve the column widths or in some instances the row heights, and while it will also copy shapes and other objects in the Excel range, this may also cause some funky alignment issues, but for simple tables and Excel ranges, it is very good:

$name = str_replace(' ', '_', $name);

They are the same, but in C++ there's a good reason to always use const on the right. You'll be consistent everywhere because const member functions must be declared this way:

int getInt() const;

It changes the this pointer in the function from Foo * const to Foo const * const. See here.

Browsers and OS's determine the style of the select boxes in most cases, and it's next to impossible to alter them with CSS alone. You'll have to look into replacement methods. The main trick is to apply appearance: none which lets you override some of the styling.

My favourite method is this one:

http://cssdeck.com/item/265/styling-select-box-with-css3

It doesn't replace the OS select menu UI element so all the problems related to doing that are non-existant (not being able to break out of the browser window with a long list being the main one).

Good luck :)

Creat XML called border.xml in drawable folder as below :

<?xml version="1.0" encoding="utf-8"?>
 <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
  <item> 
    <shape android:shape="rectangle">
      <solid android:color="#FF0000" /> 
    </shape>
  </item>   
    <item android:left="5dp" android:right="5dp"  android:top="5dp" >  
     <shape android:shape="rectangle"> 
      <solid android:color="#000000" />
    </shape>
   </item>    
 </layer-list>

then add this to linear layout as backgound as this:

     android:background="@drawable/border"

Combining matty-j suggestion with the snippet of the question, I ended up with this code focusing on resizing the grid after the data was loaded.

The HTML:

<div ng-grid="gridOptions" class="gridStyle"></div>

The directive:

angular.module('myApp.directives', [])
    .directive('resize', function ($window) {
        return function (scope, element) {

            var w = angular.element($window);
            scope.getWindowDimensions = function () {
                return { 'h': w.height(), 'w': w.width() };
            };
            scope.$watch(scope.getWindowDimensions, function (newValue, oldValue) {

                // resize Grid to optimize height
                $('.gridStyle').height(newValue.h - 250);
            }, true);

            w.bind('resize', function () {
                scope.$apply();
            });
        }
    });

The controller:

angular.module('myApp').controller('Admin/SurveyCtrl', function ($scope, $routeParams, $location, $window, $timeout, Survey) {

    // Retrieve data from the server
    $scope.surveys = Survey.query(function(data) {

        // Trigger resize event informing elements to resize according to the height of the window.
        $timeout(function () {
            angular.element($window).resize();
        }, 0)
    });

    // Configure ng-grid.
    $scope.gridOptions = {
        data: 'surveys',
        ...
    };
}

Creating a tableview using tableViewController .

import UIKit

class TableViewController: UITableViewController
{
    let tableViewModel = TableViewModel()
    var product: [String] = []
    var price: [String] = []
    override func viewDidLoad()
    {
        super.viewDidLoad()
        self.tableView.contentInset = UIEdgeInsetsMake( 20, 20 , 0, 0)
        let priceProductDetails = tableViewModel.dataProvider()

        for (key, value) in priceProductDetails
        {
            product.append(key)
            price.append(value)
        }
    }

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
    {
        return product.count
    }

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
    {
        let cell = UITableViewCell(style: .Value1, reuseIdentifier: "UITableViewCell")
        cell.textLabel?.text = product[indexPath.row]
        cell.detailTextLabel?.text = price[indexPath.row]
        return cell
    }

    override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath)
    {
        print("You tapped cell number \(indexPath.row).")
    }
}

I have a partial answer for you. This is based on what I get from GCC:

__DATE__ gives something like "Jul 27 2012"

__TIME__ gives something like 21:06:19

Put this text in an include file called build_defs.h:

#ifndef BUILD_DEFS_H

#define BUILD_DEFS_H


#define BUILD_YEAR ((__DATE__[7] - '0') * 1000 +  (__DATE__[8] - '0') * 100 + (__DATE__[9] - '0') * 10 + __DATE__[10] - '0')

#define BUILD_DATE ((__DATE__[4] - '0') * 10 + __DATE__[5] - '0')


#if 0
#if (__DATE__[0] == 'J' && __DATE__[1] == 'a' && __DATE__[2] == 'n')
    #define BUILD_MONTH  1
#elif (__DATE__[0] == 'F' && __DATE__[1] == 'e' && __DATE__[2] == 'b')
    #define BUILD_MONTH  2
#elif (__DATE__[0] == 'M' && __DATE__[1] == 'a' && __DATE__[2] == 'r')
    #define BUILD_MONTH  3
#elif (__DATE__[0] == 'A' && __DATE__[1] == 'p' && __DATE__[2] == 'r')
    #define BUILD_MONTH  4
#elif (__DATE__[0] == 'M' && __DATE__[1] == 'a' && __DATE__[2] == 'y')
    #define BUILD_MONTH  5
#elif (__DATE__[0] == 'J' && __DATE__[1] == 'u' && __DATE__[2] == 'n')
    #define BUILD_MONTH  6
#elif (__DATE__[0] == 'J' && __DATE__[1] == 'u' && __DATE__[2] == 'l')
    #define BUILD_MONTH  7
#elif (__DATE__[0] == 'A' && __DATE__[1] == 'u' && __DATE__[2] == 'g')
    #define BUILD_MONTH  8
#elif (__DATE__[0] == 'S' && __DATE__[1] == 'e' && __DATE__[2] == 'p')
    #define BUILD_MONTH  9
#elif (__DATE__[0] == 'O' && __DATE__[1] == 'c' && __DATE__[2] == 't')
    #define BUILD_MONTH 10
#elif (__DATE__[0] == 'N' && __DATE__[1] == 'o' && __DATE__[2] == 'v')
    #define BUILD_MONTH 11
#elif (__DATE__[0] == 'D' && __DATE__[1] == 'e' && __DATE__[2] == 'c')
    #define BUILD_MONTH 12
#else
    #error "Could not figure out month"
#endif
#endif

#define BUILD_HOUR ((__TIME__[0] - '0') * 10 + __TIME__[1] - '0')
#define BUILD_MIN ((__TIME__[3] - '0') * 10 + __TIME__[4] - '0')
#define BUILD_SEC ((__TIME__[6] - '0') * 10 + __TIME__[7] - '0')

#endif // BUILD_DEFS_H

I tested the above with GCC on Linux. It all works great, except for the problem that I can't figure out how to get a number for the month. If you check the section that is under #if 0 you will see my attempt to figure out the month. GCC complains with this message:

error: token ""Jul 27 2012"" is not valid in preprocessor expressions

It would be trivial to convert the three-letter month abbreviation into some sort of unique number; just subtract 'A' from the first letter and 'a' from the second and the third, and then convert to a base-26 number or something. But I want to make it evaluate to 1 for January and so on, and I can't figure out how to do that.

EDIT: I just realized that you asked for strings, not expressions that evaluate to integer values.

I tried to use these tricks to build a static string:

#define BUILD_MAJOR 1
#define BUILD_MINOR 4
#define VERSION STRINGIZE(BUILD_MAJOR) "." STRINGIZE(BUILD_MINOR)

char build_str[] = {
    BUILD_MAJOR + '0', '.' BUILD_MINOR + '0', '.',
    __DATE__[7], __DATE__[8], __DATE__[9], __DATE__[10],
    '\0'
};

GCC complains that "initializer element is not constant" for __DATE__.

Sorry, I'm not sure how to help you. Maybe you can try this stuff with your compiler? Or maybe it will give you an idea.

Good luck.

P.S. If you don't need things to be numbers, and you just want a unique build string, it's easy:

const char *build_str = "Version: " VERSION " " __DATE__ " " __TIME__;

With GCC, this results in something like:

Version: 1.4 Jul 27 2012 21:53:59

I have a similar problem importing those libs. I am using Anaconda Navigator 1.8.2 with Spyder 3.2.8.

My code is the following:

import matplotlib.pyplot as plt
import tensorflow as tf
import numpy as np
import math

#from tf.keras.models import Sequential  # This does not work!
from tensorflow.python.keras.models import Sequential
from tensorflow.python.keras.layers import InputLayer, Input
from tensorflow.python.keras.layers import Reshape, MaxPooling2D
from tensorflow.python.keras.layers import Conv2D, Dense, Flatten

I get the following error:

from tensorflow.python.keras.models import Sequential

ModuleNotFoundError: No module named 'tensorflow.python.keras'

I solve this erasing tensorflow.python

With this code I solve the error:

import matplotlib.pyplot as plt
import tensorflow as tf
import numpy as np
import math

#from tf.keras.models import Sequential  # This does not work!
from keras.models import Sequential
from keras.layers import InputLayer, Input
from keras.layers import Reshape, MaxPooling2D
from keras.layers import Conv2D, Dense, Flatten

Use:

filename=$1
IFS=$'\n'
for next in `cat $filename`; do
    echo "$next read from $filename" 
done
exit 0

If you have set IFS differently you will get odd results.

Get cursor on top, where white header with file name, then press Alt. To set top menu by default always visible. You needed in top menu selected: FILE -> Config... -> autoHideMenuBar: true (change it to autoHideMenuBar: false) Save it.

A list is considered to be False if it has no elements, so you can do something like this:

{% if mylist %}
    <p>I have a list!</p>
{% else %}
    <p>I don't have a list!</p>
{% endif %}

This is to ensure some other site can't do nasty tricks to try to steal your data. For example, by replacing the array constructor, then including this JSON URL via a <script> tag, a malicious third-party site could steal the data from the JSON response. By putting a while(1); at the start, the script will hang instead.

A same-site request using XHR and a separate JSON parser, on the other hand, can easily ignore the while(1); prefix.

use the CKEditor.editor.getData() call on the instance. That is to say:

HTML

<textarea id="my-editor">
<input id="send" type="button" value="Send">

JS for CKEditor 4.0.x

$('#send').click(function() {
    var value = CKEDITOR.instances['DOM-ID-HERE'].getData()
    // send your ajax request with value
    // profit!
});

JS for CKEditor 3.6.x

var editor = CKEDITOR.editor.replace('my-editor');

$('#send').click(function() {
    var value = editor.getData();
    // send your ajax request with value
    // profit!
});

I had need of some symbolic constants in pyparsing to represent left and right associativity of binary operators. I used class constants like this:

# an internal class, not intended to be seen by client code
class _Constants(object):
    pass


# an enumeration of constants for operator associativity
opAssoc = _Constants()
opAssoc.LEFT = object()
opAssoc.RIGHT = object()

Now when client code wants to use these constants, they can import the entire enum using:

import opAssoc from pyparsing

The enumerations are unique, they can be tested with 'is' instead of '==', they don't take up a big footprint in my code for a minor concept, and they are easily imported into the client code. They don't support any fancy str() behavior, but so far that is in the YAGNI category.

In the spirit of a DVCS (as in "Distributed"), you don't cancel something you have published:
Pull requests are essentially patches you have send (normally by email, here by GitHub webapp), and you wouldn't cancel an email either ;)

But since the GitHub Pull Request system also includes a discussion section, that would be there that you could voice your concern to the recipient of those changes, asking him/her to disregards 29 of your 30 commits.

Finally, remember:

• a/ you have a preview section when making a pull request, allowing you to see the number of commits about to be included in it, and to review their diff.
• b/ it is preferable to rebase the work you want to publish as pull request on top of the remote branch which will receive said work. Then you can make a pull request which could be safely applied in a fast forward manner by the recipient.

That being said, since January 2011 ("Refreshed Pull Request Discussions"), and mentioned in the answer above, you can close a pull request in the comments.
Look for that "Comment and Close" button at the bottom of the discussion page:

The curl installed by default in Debian supports HTTPS since a great while back. (a long time ago there were two separate packages, one with and one without SSL but that's not the case anymore)

OPTIONS /path

You can send an OPTIONS request with curl like this:

curl -i -X OPTIONS http://example.org/path

You may also use -v instead of -i to see more output.

OPTIONS *

To send a plain * (instead of the path, see RFC 7231) with the OPTIONS method, you need curl 7.55.0 or later as then you can run a command line like:

curl -i --request-target "*" -X OPTIONS http://example.org

you could use a cursor:

DECLARE @id int
DECLARE @pass varchar(100)

DECLARE cur CURSOR FOR SELECT Id, Password FROM @temp
OPEN cur

FETCH NEXT FROM cur INTO @id, @pass

WHILE @@FETCH_STATUS = 0 BEGIN
    EXEC mysp @id, @pass ... -- call your sp here
    FETCH NEXT FROM cur INTO @id, @pass
END

CLOSE cur    
DEALLOCATE cur

I have just installed the JDK for version 21 of Java SE 7 and found that it is installed in a different directory from Apple's Java 6. It is in /Library/Java... rather then in /System/Library/Java.... Running /usr/libexec/java_home -v 1.7 versus -v 1.6 will confirm this.

from int to byte:

bytes_string = int_v.to_bytes( lenth, endian )

where the lenth is 1/2/3/4...., and endian could be 'big' or 'little'

form bytes to int:

data_list = list( bytes );

You don't have to bind parameters if you use query builder or eloquent ORM. However, if you use DB::raw(), ensure that you binding the parameters.

Try the following:

$array = array(1,2,3);       $query = DB::table('offers');             $query->select('id', 'business_id', 'address_id', 'title', 'details', 'value', 'total_available', 'start_date', 'end_date', 'terms', 'type', 'coupon_code', 'is_barcode_available', 'is_exclusive', 'userinformations_id', 'is_used');             $query->leftJoin('user_offer_collection', function ($join) use ($array)             {                 $join->on('user_offer_collection.offers_id', '=', 'offers.id')                       ->whereIn('user_offer_collection.user_id', $array);             });       $query->get(); 

Use numpy.asscalar to convert a numpy array / matrix a scalar value:

>>> a=numpy.array([[[[42]]]])
>>> numpy.asscalar(a)
42

The output data type is the same type returned by the input’s item method.

It has built in error-checking if there is more than an single element:

>>> a=numpy.array([1, 2])
>>> numpy.asscalar(a)

gives:

ValueError: can only convert an array of size 1 to a Python scalar

Note: the object passed to asscalar must respond to item, so passing a list or tuple won't work.

// Step 1, update your constraint
self.myOutletToConstraint.constant = 50; // New height (for example)

// Step 2, trigger animation
[UIView animateWithDuration:2.0 animations:^{

    // Step 3, call layoutIfNeeded on your animated view's parent
    [self.view layoutIfNeeded];
}];

Or about the best module I have found http://pypi.python.org/pypi/colorama

jQuery .val()

  var foo = $('#multiple').val(); 

Update: I have found a better/proper way to solve this problem using a BehaviorSubject or an Observable rather than an EventEmitter. Please see this answer: https://stackoverflow.com/a/35568924/215945

Also, the Angular docs now have a cookbook example that uses a Subject.

Original/outdated/wrong answer: again, don't use an EventEmitter in a service. That is an anti-pattern.

Using beta.1... NavService contains the EventEmiter. Component Navigation emits events via the service, and component ObservingComponent subscribes to the events.

nav.service.ts

import {EventEmitter} from 'angular2/core';
export class NavService {
  navchange: EventEmitter<number> = new EventEmitter();
  constructor() {}
  emitNavChangeEvent(number) {
    this.navchange.emit(number);
  }
  getNavChangeEmitter() {
    return this.navchange;
  }
}

components.ts

import {Component} from 'angular2/core';
import {NavService} from '../services/NavService';

@Component({
  selector: 'obs-comp',
  template: `obs component, item: {{item}}`
})
export class ObservingComponent {
  item: number = 0;
  subscription: any;
  constructor(private navService:NavService) {}
  ngOnInit() {
    this.subscription = this.navService.getNavChangeEmitter()
      .subscribe(item => this.selectedNavItem(item));
  }
  selectedNavItem(item: number) {
    this.item = item;
  }
  ngOnDestroy() {
    this.subscription.unsubscribe();
  }
}

@Component({
  selector: 'my-nav',
  template:`
    <div class="nav-item" (click)="selectedNavItem(1)">nav 1 (click me)</div>
    <div class="nav-item" (click)="selectedNavItem(2)">nav 2 (click me)</div>
  `,
})
export class Navigation {
  item = 1;
  constructor(private navService:NavService) {}
  selectedNavItem(item: number) {
    console.log('selected nav item ' + item);
    this.navService.emitNavChangeEvent(item);
  }
}

The only solution is to use less data in your Unique Index. Your key can be NVARCHAR(450) at most.

"SQL Server retains the 900-byte limit for the maximum total size of all index key columns."

Since the answer for me was buried in the comments. For SQL Server 2012 and beyond, you can use the following:

BACKUP LOG Database TO DISK='NUL:'
DBCC SHRINKFILE (Database_Log, 1)

Here is a modification for the prev. answer. The main difference is when the user is not authenticated, it uses the original "HandleUnauthorizedRequest" method to redirect to login page:

   protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
    {

        if (filterContext.HttpContext.User.Identity.IsAuthenticated) {

            filterContext.Result = new RedirectToRouteResult(
                        new RouteValueDictionary(
                            new
                            {
                                controller = "Account",
                                action = "Unauthorised"
                            })
                        );
        }
        else
        {
             base.HandleUnauthorizedRequest(filterContext);
        }
    }

I had a similar problem finding the source of an object's method. The object name was myTree and its method was load. I put a breakpoint on the line that the method was called. By reloading the page, the execution stopped at that point. Then on the DevTools console, I typed the object along with the method name, i.e. myTree.load and hit Enter. The definition of the method was printed on the console:

Also, by right click on the definition, you can go to its definition in the source code:

So far, it looks like the answer that works is this one.

To break it out further, what worked for me was this:

Get-Variable -Name foo -Scope Global -ea SilentlyContinue | out-null

$? returns either true or false.

The latest dwr (http://directwebremoting.org/dwr/index.html) has ajax file uploads, complete with examples and nice stuff for users (like progress indicators and such).

It looks pretty nifty and dwr is fairly easy to use in general so this will be pretty good as well.

Step 1 Write all file SHA1s to a text file:

git rev-list --objects --all | sort -k 2 > allfileshas.txt

Step 2 Sort the blobs from biggest to smallest and write results to text file:

git gc && git verify-pack -v .git/objects/pack/pack-*.idx | egrep "^\w+ blob\W+[0-9]+ [0-9]+ [0-9]+$" | sort -k 3 -n -r > bigobjects.txt

Step 3a Combine both text files to get file name/sha1/size information:

for SHA in `cut -f 1 -d\  < bigobjects.txt`; do
echo $(grep $SHA bigobjects.txt) $(grep $SHA allfileshas.txt) | awk '{print $1,$3,$7}' >> bigtosmall.txt
done;

Step 3b If you have file names or path names containing spaces try this variation of Step 3a. It uses cut instead of awk to get the desired columns incl. spaces from column 7 to end of line:

for SHA in `cut -f 1 -d\  < bigobjects.txt`; do
echo $(grep $SHA bigobjects.txt) $(grep $SHA allfileshas.txt) | cut -d ' ' -f'1,3,7-' >> bigtosmall.txt
done;

Now you can look at the file bigtosmall.txt in order to decide which files you want to remove from your Git history.

Step 4 To perform the removal (note this part is slow since it's going to examine every commit in your history for data about the file you identified):

git filter-branch --tree-filter 'rm -f myLargeFile.log' HEAD

Use > and < for 'greater-than' and 'less-than' respectively

The preferred method is to use nginx or another web server to serve static files; they'll be able to do it more efficiently than Flask.

However, you can use send_from_directory to send files from a directory, which can be pretty convenient in some situations:

from flask import Flask, request, send_from_directory

# set the project root directory as the static folder, you can set others.
app = Flask(__name__, static_url_path='')

@app.route('/js/<path:path>')
def send_js(path):
    return send_from_directory('js', path)

if __name__ == "__main__":
    app.run()

Do not use send_file or send_static_file with a user-supplied path.

send_static_file example:

from flask import Flask, request
# set the project root directory as the static folder, you can set others.
app = Flask(__name__, static_url_path='')

@app.route('/')
def root():
    return app.send_static_file('index.html')

$(window).bind('beforeunload', function(e) { 
    return "Unloading this page may lose data. What do you want to do..."
    e.preventDefault();
});

The latest JDBC MSSQL connectivity driver can be found on JDBC 4.0

The class file should be in the classpath. If you are using eclipse you can easily do the same by doing the following -->

Right Click Project Name --> Properties --> Java Build Path --> Libraries --> Add External Jars

Also as already been pointed out by @Cheeso the correct way to access is jdbc:sqlserver://server:port;DatabaseName=dbname

Meanwhile please find a sample class for accessing MSSQL DB (2008 in my case).

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class ConnectMSSQLServer
{
   public void dbConnect(String db_connect_string,
            String db_userid,
            String db_password)
   {
      try {
         Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
         Connection conn = DriverManager.getConnection(db_connect_string,
                  db_userid, db_password);
         System.out.println("connected");
         Statement statement = conn.createStatement();
         String queryString = "select * from SampleTable";
         ResultSet rs = statement.executeQuery(queryString);
         while (rs.next()) {
            System.out.println(rs.getString(1));
         }
         conn.close();
      } catch (Exception e) {
         e.printStackTrace();
      }
   }

   public static void main(String[] args)
   {
      ConnectMSSQLServer connServer = new ConnectMSSQLServer();
      connServer.dbConnect("jdbc:sqlserver://xx.xx.xx.xxxx:1433;databaseName=MyDBName", "DB_USER","DB_PASSWORD");
   }
}

Hope this helps.

simply run the following command:

ng update

note: this will not update globally.

You get this message when you've used async in your template, but are referring to an object that isn't an Observable.

So for examples sake, lets' say I had these properties in my class:

job:Job
job$:Observable<Job>

Then in my template, I refer to it this way:

{{job | async }}

instead of:

{{job$ | async }}

You wouldn't need the job:Job property if you use the async pipe, but it serves to illustrate a cause of the error.

Recently had the same problem: TypeError: $(...).slick is not a function

Found an interesting solution. Hope, it might be useful to somebody.

In my particular situation there are: jQuery + WHMCS + slick. It works normal standalone, without WHMCS. But after the integration to WHMCS an error appears.

The solution was to use jQuery in noConflict mode.

Ex: Your code:

$(document).ready(function() { 
  $('a').click( function(event) {
    $(this).hide();
    event.preventDefault();
  });
});

Code in noConflict mode:

var $jq = jQuery.noConflict();
$jq(document).ready(function() { 
  $jq('a').click( function(event) {
    $jq(this).hide();
    event.preventDefault();
  });
});

The solution was found here: http://zenverse.net/jquery-how-to-fix-the-is-not-a-function-error-using-noconflict/

1) Suppose you create a SEQUENCE like shown below:

CREATE SEQUENCE TESTSEQ
INCREMENT BY 1
MINVALUE 1
MAXVALUE 500
NOCACHE
NOCYCLE
NOORDER

2) Now you fetch values from SEQUENCE. Lets say I have fetched four times as shown below.

SELECT TESTSEQ.NEXTVAL FROM dual
SELECT TESTSEQ.NEXTVAL FROM dual
SELECT TESTSEQ.NEXTVAL FROM dual
SELECT TESTSEQ.NEXTVAL FROM dual

3) After executing above four commands the value of the SEQUENCE will be 4. Now suppose I have reset the value of the SEQUENCE to 1 again. The follow the following steps. Follow all the steps in the same order as shown below:

1. ALTER SEQUENCE TESTSEQ INCREMENT BY -3;
2. SELECT TESTSEQ.NEXTVAL FROM dual
3. ALTER SEQUENCE TESTSEQ INCREMENT BY 1;
4. SELECT TESTSEQ.NEXTVAL FROM dual

Use a setter for the ViewChild:

 private contentPlaceholder: ElementRef;

 @ViewChild('contentPlaceholder') set content(content: ElementRef) {
    if(content) { // initially setter gets called with undefined
        this.contentPlaceholder = content;
    }
 }

The setter is called with an element reference once *ngIf becomes true.

Note, for Angular 8 you have to make sure to set { static: false }, which is a default setting in other Angular versions:

 @ViewChild('contentPlaceholder', { static: false })

Note: if contentPlaceholder is a component you can change ElementRef to your component Class:

  private contentPlaceholder: MyCustomComponent;

  @ViewChild('contentPlaceholder') set content(content: MyCustomComponent) {
     if(content) { // initially setter gets called with undefined
          this.contentPlaceholder = content;
     }
  }

Adding this in the index.html head worked for me:

<style>
    html, body, #app, #app>div { position: absolute; width: 100% !important; height: 100% !important; }
</style>

Use the put method: https://developer.android.com/reference/org/json/JSONObject.html

JSONObject person =  jsonArray.getJSONObject(0).getJSONObject("person");
person.put("name", "Sammie");

Generally if the installation went smoothly, it will create the desktop icons/folders. Maybe check the installation summary log to see if there's any underlying errors.

I had the same problem running windows 7-64 with VB6. I tried the unregister and re-register solutions above but it did not solve the problem. Then I noticed that in my VB6 Components I had references to both the Microsoft Windows Common Controls -2 6.0(SP6) and Microsoft Windows Common Controls -3 6.0(SP5). I removed the SP5 reference and all now works OK. It seems that -2 6.0 SP6 supersedes -3 6.0 (SP5) and when both are present there are two references to the same control. Hope this helps. Steve

You have a space delimited file, so use the module designed for reading delimited values files, csv.

import csv

with open('path/to/file.txt') as inf:
    reader = csv.reader(inf, delimiter=" ")
    second_col = list(zip(*reader))[1]
    # In Python2, you can omit the `list(...)` cast

The zip(*iterable) pattern is useful for converting rows to columns or vice versa. If you're reading a file row-wise...

>>> testdata = [[1, 2, 3],
                [4, 5, 6],
                [7, 8, 9]]

>>> for line in testdata:
...     print(line)

[1, 2, 3]
[4, 5, 6]
[7, 8, 9]

...but need columns, you can pass each row to the zip function

>>> testdata_columns = zip(*testdata)
# this is equivalent to zip([1,2,3], [4,5,6], [7,8,9])

>>> for line in testdata_columns:
...     print(line)

[1, 4, 7]
[2, 5, 8]
[3, 6, 9]

I have used simple linux shell piping + perl to convert hive generated output from tsv to csv.

hive -e "SELECT col1, col2, … FROM table_name" | perl -lpe 's/"/\\"/g; s/^|$/"/g; s/\t/","/g' > output_file.csv

(I got the updated perl regex from someone in stackoverflow some time ago)

The result will be like regular csv:

"col1","col2","col3"... and so on

Use number formatter to format the value, as required. Please check this.

MD5 has its weaknesses (see Wikipedia), so there are some projects, which try to precompute Hashes. Wikipedia does also hint at some of these projects. One I know of (and respect) is ophrack. You can not tell the user their own password, but you might be able to tell them a password that works. But i think: Just mail thrm a new password in case they forgot.

None of the answers return false for empty strings, a fix for that...

function is_numeric(n)
{
 return (n != '' && !isNaN(parseFloat(n)) && isFinite(n));
}

For Microsoft, the answer is different. VS2013 is largely C99 compliant but "[t]he hh, j, z, and t length prefixes are not supported." For size_t "that is, unsigned __int32 on 32-bit platforms, unsigned __int64 on 64-bit platforms" use prefix I (capital eye) with type specifier o, u, x, or X. See VS2013 Size specification

As for off_t, it is defined as long in VC\include\sys\types.h.

You should provide the second database information in `application/config/database.php´

Normally, you would set the default database group, like so:

$db['default']['hostname'] = "localhost";
$db['default']['username'] = "root";
$db['default']['password'] = "";
$db['default']['database'] = "database_name";
$db['default']['dbdriver'] = "mysql";
$db['default']['dbprefix'] = "";
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = FALSE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = "";
$db['default']['char_set'] = "utf8";
$db['default']['dbcollat'] = "utf8_general_ci";
$db['default']['swap_pre'] = "";
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;

Notice that the login information and settings are provided in the array named $db['default'].

You can then add another database in a new array - let's call it 'otherdb'.

$db['otherdb']['hostname'] = "localhost";
$db['otherdb']['username'] = "root";
$db['otherdb']['password'] = "";
$db['otherdb']['database'] = "other_database_name";
$db['otherdb']['dbdriver'] = "mysql";
$db['otherdb']['dbprefix'] = "";
$db['otherdb']['pconnect'] = TRUE;
$db['otherdb']['db_debug'] = FALSE;
$db['otherdb']['cache_on'] = FALSE;
$db['otherdb']['cachedir'] = "";
$db['otherdb']['char_set'] = "utf8";
$db['otherdb']['dbcollat'] = "utf8_general_ci";
$db['otherdb']['swap_pre'] = "";
$db['otherdb']['autoinit'] = TRUE;
$db['otherdb']['stricton'] = FALSE;

Now, to actually use the second database, you have to send the connection to another variabel that you can use in your model:

function my_model_method()
{
  $otherdb = $this->load->database('otherdb', TRUE); // the TRUE paramater tells CI that you'd like to return the database object.

  $query = $otherdb->select('first_name, last_name')->get('person');
  var_dump($query);
}

That should do it. The documentation for connecting to multiple databases can be found here: http://codeigniter.com/user_guide/database/connecting.html

Let's say you have a variable named "Hello World" and if you want to split it and store it into two different variables you can use like this:

var fullText = "Hello World"
let firstWord = fullText.text?.components(separatedBy: " ").first
let lastWord = fullText.text?.components(separatedBy: " ").last

I use FileZilla and it works fine with SFTP (SSH File Transfer Protocol). Follow these steps to install it and configure it:

1. Install FileZilla via terminal:

sudo apt-get install filezilla

2. Open the program and go to File -> Site Manager... or simply type Ctrl+S

3. The following window should appear:

4. Enter the name of your host, select the port (usually 22 for ssh/scp/sftp) and choose SFTP - SSH File Transfer Protocol as protocol and optionally set the Logon Type to Normal if authentication is needed, resp. enter your data.

The script isn't even necessary, split(1) supports the wanted feature out of the box:
split -l 75 auth.log auth.log. The above command splits the file in chunks of 75 lines a piece, and outputs file on the form: auth.log.aa, auth.log.ab, ...

wc -l on the original file and output gives:

  321 auth.log
   75 auth.log.aa
   75 auth.log.ab
   75 auth.log.ac
   75 auth.log.ad
   21 auth.log.ae
  642 total

myList.Count is a method on the list object, it just returns the value of a field so is very fast. As it is a small method it is very likely to be inlined by the compiler (or runtime), they may then allow other optimization to be done by the compiler.

myList.Count() is calling an extension method (introduced by LINQ) that loops over all the items in an IEnumerable, so should be a lot slower.

However (In the Microsoft implementation) the Count extension method has a “special case” for Lists that allows it to use the list’s Count property, this means the Count() method is only a little slower than the Count property.

It is unlikely you will be able to tell the difference in speed in most applications.

So if you know you are dealing with a List use the Count property, otherwise if you have a "unknown" IEnumerabl, use the Count() method and let it optimise for you.

You can check the ASCII´s number with this code.

String name = "admin";
char a1 = a.charAt(0);
int a2 = a1;
System.out.println("The number is : "+a2); // the value is 97

If I am wrong, apologies.

You can simply audit your code and then

#sudo su 
rm -rf package-lock.json node_modules
sudo npm i --save 

I don't know about all the lifecycle hooks, but as for destruction, ngOnDestroy actually get called on Injectable when it's provider is destroyed (for example an Injectable supplied by a component).

From the docs :

Lifecycle hook that is called when a directive, pipe or service is destroyed.

Just in case anyone is interested in destruction check this question:

The error also happens when trying to use the

with multiprocessing.Pool() as pool:
   # ...

with a Python version that is too old (like Python 2.X) and does not support using with together with multiprocessing pools.

(See this answer https://stackoverflow.com/a/25968716/1426569 to another question for more details)

Use the below code:

import base64

#Taking input through the terminal.
welcomeInput= raw_input("Enter 1 to convert String to Base64, 2 to convert Base64 to String: ") 

if(int(welcomeInput)==1 or int(welcomeInput)==2):
    #Code to Convert String to Base 64.
    if int(welcomeInput)==1:
        inputString= raw_input("Enter the String to be converted to Base64:") 
        base64Value = base64.b64encode(inputString.encode())
        print "Base64 Value = " + base64Value
    #Code to Convert Base 64 to String.
    elif int(welcomeInput)==2:
        inputString= raw_input("Enter the Base64 value to be converted to String:") 
        stringValue = base64.b64decode(inputString).decode('utf-8')
        print "Base64 Value = " + stringValue

else:
    print "Please enter a valid value."

No, there's no direct not operator. At least not the way you hope for.

You can use a zero-width negative lookahead, however:

\((?!2001)[0-9a-zA-z _\.\-:]*\)

The (?!...) part means "only match if the text following (hence: lookahead) this doesn't (hence: negative) match this. But it doesn't actually consume the characters it matches (hence: zero-width).

There are actually 4 combinations of lookarounds with 2 axes:

• lookbehind / lookahead : specifies if the characters before or after the point are considered
• positive / negative : specifies if the characters must match or must not match.

Please use if condition with while loop and try.

eg.

if ($result = $conn->query($query)) {

    /* fetch associative array */
    while ($row = $result->fetch_assoc()) {

    }
    /* free result set */
    $result->free();
}

You can do it in two different ways.

Option 1: The -eq operator

>$a = "is"
>$b = "fission"
>$c = "is"
>$a -eq $c
True
>$a -eq $b
False

Option 2: The .Equals() method of the string object. Because strings in PowerShell are .Net System.String objects, any method of that object can be called directly.

>$a.equals($b)
False
>$a.equals($c)
True
>$a|get-member -membertype method

List of System.String methods follows.

It works, when you use both lines:

Application.ActiveWorkbook.Worksheets("data").Range("C1", "C20000") = Format(Date, "yyyy-mm-dd")
Application.ActiveWorkbook.Worksheets("data").Range("C1", "C20000").NumberFormat = "yyyy-mm-dd"

One other alternative is to use function name in #if. The #if will detect if the parameter is function and if it is then it will call it and use its return for truthyness check. Below myFunction gets current context as this.

{{#if myFunction}}
  I'm Happy!
{{/if}}

It's definitely not a problem with propeties file not being found, since in that case another exception is thrown.

Make sure that you actually have a value with key idm.url in your idm.properties.

The easiest approach which I have used is

var found = arr.find(function(element) {
         return element.name === "k1";
 });

//If you print the found :
console.log(found);
=> Object { name: "k1", value: "abc" }

//If you need the value
console.log(found.value)
=> "abc"

The similar approach can be used to find the values from the JSON Array based on any input data from the JSON.

The process for timing out an operations is described in the documentation for signal.

The basic idea is to use signal handlers to set an alarm for some time interval and raise an exception once that timer expires.

Note that this will only work on UNIX.

Here's an implementation that creates a decorator (save the following code as timeout.py).

from functools import wraps
import errno
import os
import signal

class TimeoutError(Exception):
    pass

def timeout(seconds=10, error_message=os.strerror(errno.ETIME)):
    def decorator(func):
        def _handle_timeout(signum, frame):
            raise TimeoutError(error_message)

        def wrapper(*args, **kwargs):
            signal.signal(signal.SIGALRM, _handle_timeout)
            signal.alarm(seconds)
            try:
                result = func(*args, **kwargs)
            finally:
                signal.alarm(0)
            return result

        return wraps(func)(wrapper)

    return decorator

This creates a decorator called @timeout that can be applied to any long running functions.

So, in your application code, you can use the decorator like so:

from timeout import timeout

# Timeout a long running function with the default expiry of 10 seconds.
@timeout
def long_running_function1():
    ...

# Timeout after 5 seconds
@timeout(5)
def long_running_function2():
    ...

# Timeout after 30 seconds, with the error "Connection timed out"
@timeout(30, os.strerror(errno.ETIMEDOUT))
def long_running_function3():
    ...

Based on @mbaird's advice, I found a workable solution by subclassing the ImageView class and overriding onLayout(). I then created an observer interface which my activity implemented and passed a reference to itself to the class, which allowed it to tell the activity when it was actually finished sizing.

I'm not 100% convinced that this is the best solution (hence my not marking this answer as correct just yet), but it does work and according to the documentation is the first time when one can find the actual size of a view.

#'re.IGNORECASE' for case insensitive results short form re.I
#'re.match' returns the first match located from the start of the string. 
#'re.search' returns location of the where the match is found 
#'re.compile' creates a regex object that can be used for multiple matches

 >>> s = r'TeSt'   
 >>> print (re.match(s, r'test123', re.I))
 <_sre.SRE_Match object; span=(0, 4), match='test'>
 # OR
 >>> pattern = re.compile(s, re.I)
 >>> print(pattern.match(r'test123'))
 <_sre.SRE_Match object; span=(0, 4), match='test'>

If you have enabled actuator feature (spring-boot-starter-actuator), additional exclude should be added in application.yml:

spring:
  autoconfigure:
    exclude: org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration,org.springframework.boot.actuate.autoconfigure.security.servlet.ManagementWebSecurityAutoConfiguration

Tested in Spring Boot version 2.3.4.RELEASE.

Not answering to your direct questions, since there are already a lot of detailed answers, but it's worth mentioning, that to the contrary of Android documentation, Android Studio is suggesting to use the same version for compileSDKVersion and targetSDKVersion.

To search an element in an array, you can use array_search function and to remove an element from an array you can use unset function. Ex:

<?php
$hackers = array ('Alan Kay', 'Peter Norvig', 'Linus Trovalds', 'Larry Page');

print_r($hackers);

// Search
$pos = array_search('Linus Trovalds', $hackers);

echo 'Linus Trovalds found at: ' . $pos;

// Remove from array
unset($hackers[$pos]);

print_r($hackers);

You can refer: https://www.php.net/manual/en/ref.array.php for more array related functions.

I'm guessing this is a homework question, so you probably want to go here. It has a tutorial explaining linked lists, gives good pseudocode and also has a C++ implementation you can download.

I'd recommend reading through the explanation and understanding the pseudocode before blindly using the implementation. This is a topic that you really should understand in depth if you want to continue on in CS.

import android.graphics.Matrix
public Bitmap getResizedBitmap(Bitmap bm, int newWidth, int newHeight) {
    int width = bm.getWidth();
    int height = bm.getHeight();
    float scaleWidth = ((float) newWidth) / width;
    float scaleHeight = ((float) newHeight) / height;
    // CREATE A MATRIX FOR THE MANIPULATION
    Matrix matrix = new Matrix();
    // RESIZE THE BIT MAP
    matrix.postScale(scaleWidth, scaleHeight);

    // "RECREATE" THE NEW BITMAP
    Bitmap resizedBitmap = Bitmap.createBitmap(
        bm, 0, 0, width, height, matrix, false);
    bm.recycle();
    return resizedBitmap;
}

EDIT: as suggested by by @aveschini, I have added bm.recycle(); for memory leaks. Please note that in case if you are using the previous object for some other purposes, then handle accordingly.
