It's been solved.

The losses only save to the History over the epochs. I was running iterations instead of using the Keras built in epochs option.

so instead of doing 4 iterations I now have

model.fit(......, nb_epoch = 4)

Now it returns the loss for each epoch run:

print(hist.history)
{'loss': [1.4358016599558268, 1.399221191623641, 1.381293383180471, h1.3758836857303727]}

It's an old question, but I found this can be done easily with Spacy. Once the document is read, a simple api similarity can be used to find the cosine similarity between the document vectors.

import spacy
nlp = spacy.load('en')
doc1 = nlp(u'Hello hi there!')
doc2 = nlp(u'Hello hi there!')
doc3 = nlp(u'Hey whatsup?')

print doc1.similarity(doc2) # 0.999999954642
print doc2.similarity(doc3) # 0.699032527716
print doc1.similarity(doc3) # 0.699032527716

Lot of very detailed answers here but I don't think you are answering the right questions. As I understand the question, there are two concerns:

1. How to I score a multiclass problem?
2. How do I deal with unbalanced data?

1.

You can use most of the scoring functions in scikit-learn with both multiclass problem as with single class problems. Ex.:

from sklearn.metrics import precision_recall_fscore_support as score

predicted = [1,2,3,4,5,1,2,1,1,4,5] 
y_test = [1,2,3,4,5,1,2,1,1,4,1]

precision, recall, fscore, support = score(y_test, predicted)

print('precision: {}'.format(precision))
print('recall: {}'.format(recall))
print('fscore: {}'.format(fscore))
print('support: {}'.format(support))

This way you end up with tangible and interpretable numbers for each of the classes.

| Label | Precision | Recall | FScore | Support |
|-------|-----------|--------|--------|---------|
| 1     | 94%       | 83%    | 0.88   | 204     |
| 2     | 71%       | 50%    | 0.54   | 127     |
| ...   | ...       | ...    | ...    | ...     |
| 4     | 80%       | 98%    | 0.89   | 838     |
| 5     | 93%       | 81%    | 0.91   | 1190    |

Then...

2.

... you can tell if the unbalanced data is even a problem. If the scoring for the less represented classes (class 1 and 2) are lower than for the classes with more training samples (class 4 and 5) then you know that the unbalanced data is in fact a problem, and you can act accordingly, as described in some of the other answers in this thread. However, if the same class distribution is present in the data you want to predict on, your unbalanced training data is a good representative of the data, and hence, the unbalance is a good thing.

This is actually on the main page of nltk.org:

>>> import nltk
>>> sentence = """At eight o'clock on Thursday morning
... Arthur didn't feel very good."""
>>> tokens = nltk.word_tokenize(sentence)
>>> tokens
['At', 'eight', "o'clock", 'on', 'Thursday', 'morning',
'Arthur', 'did', "n't", 'feel', 'very', 'good', '.']

You can do it using named-entity recognition (NER). It's fairly simple and there are out-of-the-shelf tools out there to do it, such as spaCy.

NER is an NLP task where a neural network (or other method) is trained to detect certain entities, such as names, places, dates and organizations.

Example:

Sponge Bob went to South beach, he payed a ticket of $200!
I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.

Returns:

Just be aware that this is not 100%!

Here are a little snippet for you to try out:

import spacy

phrases = ['Sponge Bob went to South beach, he payed a ticket of $200!', 'I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.']
nlp = spacy.load('en')
for phrase in phrases:
   doc = nlp(phrase)
   replaced = ""
   for token in doc:
      if token in doc.ents:
         replaced+="XXXX "
      else:
         replaced+=token.text+" "

Read more here: https://spacy.io/usage/linguistic-features#named-entities

You could, instead of replacing with XXXX, replace based on the entity type, like:

if ent.label_ == "PERSON":
   replaced += "<PERSON> "

Then:

import re, random

personames = ["Jack", "Mike", "Bob", "Dylan"]

phrase = re.replace("<PERSON>", random.choice(personames), phrase)

Sincerely asking, what is a word? If your assumption is that a word consists of alphabetic characters only, you are wrong since words such as can't will be destroyed into pieces (such as can and t) if you remove punctuation before tokenisation, which is very likely to affect your program negatively.

Hence the solution is to tokenise and then remove punctuation tokens.

import string

from nltk.tokenize import word_tokenize

tokens = word_tokenize("I'm a southern salesman.")
# ['I', "'m", 'a', 'southern', 'salesman', '.']

tokens = list(filter(lambda token: token not in string.punctuation, tokens))
# ['I', "'m", 'a', 'southern', 'salesman']

...and then if you wish, you can replace certain tokens such as 'm with am.

I have similar solution but might be useful for pandas

import math
import re
from collections import Counter
import pandas as pd

WORD = re.compile(r"\w+")


def get_cosine(vec1, vec2):
    intersection = set(vec1.keys()) & set(vec2.keys())
    numerator = sum([vec1[x] * vec2[x] for x in intersection])

    sum1 = sum([vec1[x] ** 2 for x in list(vec1.keys())])
    sum2 = sum([vec2[x] ** 2 for x in list(vec2.keys())])
    denominator = math.sqrt(sum1) * math.sqrt(sum2)

    if not denominator:
        return 0.0
    else:
        return float(numerator) / denominator


def text_to_vector(text):
    words = WORD.findall(text)
    return Counter(words)

df=pd.read_csv('/content/drive/article.csv')
df['vector1']=df['headline'].apply(lambda x: text_to_vector(x)) 
df['vector2']=df['snippet'].apply(lambda x: text_to_vector(x)) 
df['simscore']=df.apply(lambda x: get_cosine(x['vector1'],x['vector2']),axis=1)

.Net lucene has an inbuilt porter stemmer. You can try that. But note that porter stemming does not consider word context when deriving the lemma. (Go through the algorithm and its implementation and you will see how it works)

@alvas's answer does the job but it can be done way faster. Assuming that you have documents: a list of strings.

from nltk.corpus import stopwords
from nltk.tokenize import wordpunct_tokenize

stop_words = set(stopwords.words('english'))
stop_words.update(['.', ',', '"', "'", '?', '!', ':', ';', '(', ')', '[', ']', '{', '}']) # remove it if you need punctuation 

for doc in documents:
    list_of_words = [i.lower() for i in wordpunct_tokenize(doc) if i.lower() not in stop_words]

Notice that due to the fact that here you are searching in a set (not in a list) the speed would be theoretically len(stop_words)/2 times faster, which is significant if you need to operate through many documents.

For 5000 documents of approximately 300 words each the difference is between 1.8 seconds for my example and 20 seconds for @alvas's.

P.S. in most of the cases you need to divide the text into words to perform some other classification tasks for which tf-idf is used. So most probably it would be better to use stemmer as well:

from nltk.stem.porter import PorterStemmer
porter = PorterStemmer()

and to use [porter.stem(i.lower()) for i in wordpunct_tokenize(doc) if i.lower() not in stop_words] inside of a loop.

Add the following to the top of your file # coding=utf-8

If you go to the link in the error you can seen the reason why:

Defining the Encoding

Python will default to ASCII as standard encoding if no other encoding hints are given. To define a source code encoding, a magic comment must be placed into the source files either as first or second line in the file, such as: # coding=

Use a convert function to get all entries for a particular day.

with Python 3.x, goes for dict comprehensions

keys = ('name', 'age', 'food')
values = ('Monty', 42, 'spam')

dic = {k:v for k,v in zip(keys, values)}

print(dic)

More on dict comprehensions here, an example is there:

>>> print {i : chr(65+i) for i in range(4)}
    {0 : 'A', 1 : 'B', 2 : 'C', 3 : 'D'}

Amazon Linux now supports python36.

python36-pip is not available. So need to follow a different route.

sudo yum install python36 python36-devel python36-libs python36-tools

# If you like to have pip3.6:
curl -O https://bootstrap.pypa.io/get-pip.py
sudo python3 get-pip.py

If you want to get the form data directly from Http request, without any model bindings or FormCollection you can use this:

[HttpPost] 
public ActionResult SubmitAction() {

    // This will return an string array of all keys in the form.
    // NOTE: you specify the keys in form by the name attributes e.g:
    // <input name="this is the key" value="some value" type="test" />
    var keys = Request.Form.AllKeys;

    // This will return the value for the keys.
    var value1 = Request.Form.Get(keys[0]);
    var value2 = Request.Form.Get(keys[1]);
}

This is very nice:

http://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/RandomStringUtils.html - something like RandomStringUtils.randomNumeric(7).

There are 10^7 equiprobable (if java.util.Random is not broken) distinct values so uniqueness may be a concern.

According to React Doc, you could listen to keyboard events, like onKeyPress or onKeyUp, not onChange.

var Input = React.createClass({
  render: function () {
    return <input type="text" onKeyDown={this._handleKeyDown} />;
  },
  _handleKeyDown: function(e) {
    if (e.key === 'Enter') {
      console.log('do validate');
    }
  }
});

Update: Use React.Component

Here is the code using React.Component which does the same thing

class Input extends React.Component {
  _handleKeyDown = (e) => {
    if (e.key === 'Enter') {
      console.log('do validate');
    }
  }

  render() {
    return <input type="text" onKeyDown={this._handleKeyDown} />
  }
}

Here is the jsfiddle.

Update 2: Use a functional component

const Input = () => {
  const handleKeyDown = (event) => {
    if (event.key === 'Enter') {
      console.log('do validate')
    }
  }

  return <input type="text" onKeyDown={handleKeyDown} />
}

$( "element" ).focusout(function() {
    //your code on element
})

When a dictionary is enumerated, it will yield KeyValuePair<TKey,TValue> objects... so you just need to specify "Value" and "Key" for DataTextField and DataValueField respectively, to select the Value/Key properties.

Thanks to Joe's comment, I reread the question to get these the right way round. Normally I'd expect the "key" in the dictionary to be the text that's displayed, and the "value" to be the value fetched. Your sample code uses them the other way round though. Unless you really need them to be this way, you might want to consider writing your code as:

list.Add(cul.DisplayName, cod);

(And then changing the binding to use "Key" for DataTextField and "Value" for DataValueField, of course.)

In fact, I'd suggest that as it seems you really do want a list rather than a dictionary, you might want to reconsider using a dictionary in the first place. You could just use a List<KeyValuePair<string, string>>:

string[] languageCodsList = service.LanguagesAvailable();
var list = new List<KeyValuePair<string, string>>();

foreach (string cod in languageCodsList)
{
    CultureInfo cul = new CultureInfo(cod);
    list.Add(new KeyValuePair<string, string>(cul.DisplayName, cod));
}

Alternatively, use a list of plain CultureInfo values. LINQ makes this really easy:

var cultures = service.LanguagesAvailable()
                      .Select(language => new CultureInfo(language));
languageList.DataTextField = "DisplayName";
languageList.DataValueField = "Name";
languageList.DataSource = cultures;
languageList.DataBind();

If you're not using LINQ, you can still use a normal foreach loop:

List<CultureInfo> cultures = new List<CultureInfo>();
foreach (string cod in service.LanguagesAvailable())
{
    cultures.Add(new CultureInfo(cod));
}
languageList.DataTextField = "DisplayName";
languageList.DataValueField = "Name";
languageList.DataSource = cultures;
languageList.DataBind();

As of Python 3.4 one can use the pathlib module to solve this.

If you happen to be on an older version, you can use the backported version found here

Let's assume you are not in the root path (just to add a bit of difficulty to it) you want to rename, and have to provide a full path, we can look at this:

some_path = 'a/b/c/the_file.extension'

So, you can take your path and create a Path object out of it:

from pathlib import Path
p = Path(some_path)

Just to provide some information around this object we have now, we can extract things out of it. For example, if for whatever reason we want to rename the file by modifying the filename from the_file to the_file_1, then we can get the filename part:

name_without_extension = p.stem

And still hold the extension in hand as well:

ext = p.suffix

We can perform our modification with a simple string manipulation:

Python 3.6 and greater make use of f-strings!

new_file_name = f"{name_without_extension}_1"

Otherwise:

new_file_name = "{}_{}".format(name_without_extension, 1)

And now we can perform our rename by calling the rename method on the path object we created and appending the ext to complete the proper rename structure we want:

p.rename(Path(p.parent, new_file_name + ext))

More shortly to showcase its simplicity:

Python 3.6+:

from pathlib import Path
p = Path(some_path)
p.rename(Path(p.parent, f"{p.stem}_1_{p.suffix}"))

Versions less than Python 3.6 use the string format method instead:

from pathlib import Path
p = Path(some_path)
p.rename(Path(p.parent, "{}_{}_{}".format(p.stem, 1, p.suffix))

var data = [
    {
        id : "001",
        name : "apple",
        category : "fruit",
        color : "red"
    },
    {
        id : "002",
        name : "melon",
        category : "fruit",
        color : "green"
    },
    {
        id : "003",
        name : "banana",
        category : "fruit",
        color : "yellow"
    }
];

for(var i = 0, len = data.length; i < length; i++) {
    var temp = '<tr><td>' + data[i].id + '</td>';
    temp+= '<td>' + data[i].name+ '</td>';
    temp+= '<td>' + data[i].category + '</td>';
    temp+= '<td>' + data[i].color + '</td></tr>';
    $('table tbody').append(temp));
}

To use in Eloquent. Add on top of your model

protected $table = 'table_name as alias'

//table_name should be exact as in your database

..then use in your query like

ModelName::query()->select(alias.id, alias.name)

With PHP 5 or superior, you may use datetime::format function (see documentation http://us.php.net/manual/en/datetime.format.php)

 echo strftime( '%e %B %Y' , 
    date_create_from_format('Y-d-m G:i:s', '2012-04-05 11:55:21')->format('U')
    );  // 4 May 2012

For fire base to install properly all the versions of the fire base compiles must be in same version so

compile 'com.google.firebase:firebase-messaging:11.0.4' 
compile 'com.google.android.gms:play-services-maps:11.0.4' 
compile 'com.google.android.gms:play-services-location:11.0.4'

this is the correct way to do it.

My problem turned out to be that I was assigning as document.getElementById("myinput").Value = '1';

Notice the capital V in Value? Once I changed it to small case, i.e., value, the data started posting. Odd as it was not giving any JavaScript errors either.

ps -fC PROCESSNAME

ps and grep is a dangerous combination -- grep tries to match everything on each line (thus the all too common: grep -v grep hack). ps -C doesn't use grep, it uses the process table for an exact match. Thus, you'll get an accurate list with: ps -fC sh rather finding every process with sh somewhere on the line.

Here is my method for that: Loading Custom UITableViewCells from XIB Files… Yet Another Method

The idea is to create a SampleCell subclass of the UITableViewCell with a IBOutlet UIView *content property and a property for each custom subview you need to configure from the code. Then to create a SampleCell.xib file. In this nib file, change the file owner to SampleCell. Add a content UIView sized to fit your needs. Add and configure all the subviews (label, image views, buttons, etc) you want. Finally, link the content view and the subviews to the file owner.

Maybe you'd like try run pip in Python shell like this:

>>> import pip
>>> pip.main(['install', 'requests'])

This will install requests package using pip.

Because pip is a module in standard library, but it isn't a built-in function(or module), so you need import it.

Other way, you should run pip in system shell(cmd. If pip is in path).

I've managed to achieve it with minimal effort (just as simple as with ASP.NET Core).

For that I use OWIN Startup.cs file and Microsoft.Owin.Security.Jwt library.

In order for the app to hit Startup.cs we need to amend Web.config:

<configuration>
  <appSettings>
    <add key="owin:AutomaticAppStartup" value="true" />
    ...

Here's how Startup.cs should look:

using MyApp.Helpers;
using Microsoft.IdentityModel.Tokens;
using Microsoft.Owin;
using Microsoft.Owin.Security;
using Microsoft.Owin.Security.Jwt;
using Owin;

[assembly: OwinStartup(typeof(MyApp.App_Start.Startup))]

namespace MyApp.App_Start
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            app.UseJwtBearerAuthentication(
                new JwtBearerAuthenticationOptions
                {
                    AuthenticationMode = AuthenticationMode.Active,
                    TokenValidationParameters = new TokenValidationParameters()
                    {
                        ValidAudience = ConfigHelper.GetAudience(),
                        ValidIssuer = ConfigHelper.GetIssuer(),
                        IssuerSigningKey = ConfigHelper.GetSymmetricSecurityKey(),
                        ValidateLifetime = true,
                        ValidateIssuerSigningKey = true
                    }
                });
        }
    }
}

Many of you guys use ASP.NET Core nowadays, so as you can see it doesn't differ a lot from what we have there.

It really got me perplexed first, I was trying to implement custom providers, etc. But I didn't expect it to be so simple. OWIN just rocks!

Just one thing to mention - after I enabled OWIN Startup NSWag library stopped working for me (e.g. some of you might want to auto-generate typescript HTTP proxies for Angular app).

The solution was also very simple - I replaced NSWag with Swashbuckle and didn't have any further issues.

Ok, now sharing ConfigHelper code:

public class ConfigHelper
{
    public static string GetIssuer()
    {
        string result = System.Configuration.ConfigurationManager.AppSettings["Issuer"];
        return result;
    }

    public static string GetAudience()
    {
        string result = System.Configuration.ConfigurationManager.AppSettings["Audience"];
        return result;
    }

    public static SigningCredentials GetSigningCredentials()
    {
        var result = new SigningCredentials(GetSymmetricSecurityKey(), SecurityAlgorithms.HmacSha256);
        return result;
    }

    public static string GetSecurityKey()
    {
        string result = System.Configuration.ConfigurationManager.AppSettings["SecurityKey"];
        return result;
    }

    public static byte[] GetSymmetricSecurityKeyAsBytes()
    {
        var issuerSigningKey = GetSecurityKey();
        byte[] data = Encoding.UTF8.GetBytes(issuerSigningKey);
        return data;
    }

    public static SymmetricSecurityKey GetSymmetricSecurityKey()
    {
        byte[] data = GetSymmetricSecurityKeyAsBytes();
        var result = new SymmetricSecurityKey(data);
        return result;
    }

    public static string GetCorsOrigins()
    {
        string result = System.Configuration.ConfigurationManager.AppSettings["CorsOrigins"];
        return result;
    }
}

Another important aspect - I sent JWT Token via Authorization header, so typescript code looks for me as follows:

(the code below is generated by NSWag)

@Injectable()
export class TeamsServiceProxy {
    private http: HttpClient;
    private baseUrl: string;
    protected jsonParseReviver: ((key: string, value: any) => any) | undefined = undefined;

    constructor(@Inject(HttpClient) http: HttpClient, @Optional() @Inject(API_BASE_URL) baseUrl?: string) {
        this.http = http;
        this.baseUrl = baseUrl ? baseUrl : "https://localhost:44384";
    }

    add(input: TeamDto | null): Observable<boolean> {
        let url_ = this.baseUrl + "/api/Teams/Add";
        url_ = url_.replace(/[?&]$/, "");

        const content_ = JSON.stringify(input);

        let options_ : any = {
            body: content_,
            observe: "response",
            responseType: "blob",
            headers: new HttpHeaders({
                "Content-Type": "application/json", 
                "Accept": "application/json",
                "Authorization": "Bearer " + localStorage.getItem('token')
            })
        };

See headers part - "Authorization": "Bearer " + localStorage.getItem('token')

Debug.Print outputs to the "Immediate" window.

Also, you can simply type ? and then a statement directly into the immediate window (and then press Enter) and have the output appear right below, like this:

This can be very handy to quickly output the property of an object...

? myWidget.name

...to set the property of an object...

myWidget.name = "thingy"

...or to even execute a function or line of code, while in debugging mode:

Sheet1.MyFunction()

In CentOS 7 with PostgreSQL 9.4 it's in the following directory:

/var/lib/pgsql/9.4/data

I can see it when I'm logged in as root.

you can use RabbitMQ API to get count or messages :

/api/queues/vhost/name/get

Get messages from a queue. (This is not an HTTP GET as it will alter the state of the queue.) You should post a body looking like:

{"count":5,"requeue":true,"encoding":"auto","truncate":50000}

count controls the maximum number of messages to get. You may get fewer messages than this if the queue cannot immediately provide them.

requeue determines whether the messages will be removed from the queue. If requeue is true they will be requeued - but their redelivered flag will be set. encoding must be either "auto" (in which case the payload will be returned as a string if it is valid UTF-8, and base64 encoded otherwise), or "base64" (in which case the payload will always be base64 encoded). If truncate is present it will truncate the message payload if it is larger than the size given (in bytes). truncate is optional; all other keys are mandatory.

Please note that the publish / get paths in the HTTP API are intended for injecting test messages, diagnostics etc - they do not implement reliable delivery and so should be treated as a sysadmin's tool rather than a general API for messaging.

http://hg.rabbitmq.com/rabbitmq-management/raw-file/rabbitmq_v3_1_3/priv/www/api/index.html

The first part of your question is easy. As already pointed out, cut accepts omission of either the starting or the ending index of a column range, interpreting this as meaning either “from the start to column n (inclusive)” or “from column n (inclusive) to the end,” respectively:

$ printf 'this:is:a:test' | cut -d: -f-2
this:is
$ printf 'this:is:a:test' | cut -d: -f3-
a:test

It also supports combining ranges. If you want, e.g., the first 3 and the last 2 columns in a row of 7 columns:

$ printf 'foo:bar:baz:qux:quz:quux:quuz' | cut -d: -f-3,6-
foo:bar:baz:quux:quuz

However, the second part of your question can be a bit trickier depending on what kind of input you’re expecting. If by “last n columns” you mean “last n columns (regardless of their indices in the overall row)” (i.e. because you don’t necessarily know how many columns you’re going to find in advance) then sadly this is not possible to accomplish using cut alone. In order to effectively use cut to pull out “the last n columns” in each line, the total number of columns present in each line must be known beforehand, and each line must be consistent in the number of columns it contains.

If you do not know how many “columns” may be present in each line (e.g. because you’re working with input that is not strictly tabular), then you’ll have to use something like awk instead. E.g., to use awk to pull out the last 2 “columns” (awk calls them fields, the number of which can vary per line) from each line of input:

$ printf '/a\n/a/b\n/a/b/c\n/a/b/c/d\n' | awk -F/ '{print $(NF-1) FS $(NF)}'
/a
a/b
b/c
c/d

1. yes you can run it on iOS and Android (Win8 is not supported!
2. no deployment as a web-app does not work

What I did to solve the problem was:

git pull origin [branch]
git push origin [branch]

Also make sure that you are pointing to the right branch by running:

git remote set-url origin [url]

Example of a Boolean (AND) plus Wildcard search, which I'm using inside a javascript Autocomplete plugin:

String to match: "my word"

String to search: "I'm searching for my funny words inside this text"

You need the following regex: /^(?=.*my)(?=.*word).*$/im

Explaining:

^ assert position at start of a line

?= Positive Lookahead

.* matches any character (except newline)

() Groups

$ assert position at end of a line

i modifier: insensitive. Case insensitive match (ignores case of [a-zA-Z])

m modifier: multi-line. Causes ^ and $ to match the begin/end of each line (not only begin/end of string)

Test the Regex here: https://regex101.com/r/iS5jJ3/1

So, you can create a javascript function that:

1. Replace regex reserved characters to avoid errors
2. Split your string at spaces
3. Encapsulate your words inside regex groups
4. Create a regex pattern
5. Execute the regex match

Example:

function fullTextCompare(myWords, toMatch){_x000D_
    //Replace regex reserved characters_x000D_
    myWords=myWords.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&');_x000D_
    //Split your string at spaces_x000D_
    arrWords = myWords.split(" ");_x000D_
    //Encapsulate your words inside regex groups_x000D_
    arrWords = arrWords.map(function( n ) {_x000D_
        return ["(?=.*"+n+")"];_x000D_
    });_x000D_
    //Create a regex pattern_x000D_
    sRegex = new RegExp("^"+arrWords.join("")+".*$","im");_x000D_
    //Execute the regex match_x000D_
    return(toMatch.match(sRegex)===null?false:true);_x000D_
}_x000D_
_x000D_
//Using it:_x000D_
console.log(_x000D_
    fullTextCompare("my word","I'm searching for my funny words inside this text")_x000D_
);_x000D_
_x000D_
//Wildcards:_x000D_
console.log(_x000D_
    fullTextCompare("y wo","I'm searching for my funny words inside this text")_x000D_
);

Try this best way :

PreferenceConnector.java

import android.content.Context;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;

public class PreferenceConnector {
    public static final String PREF_NAME = "ENUMERATOR_PREFERENCES";
    public static final String PREF_NAME_REMEMBER = "ENUMERATOR_REMEMBER";
    public static final int MODE = Context.MODE_PRIVATE;


    public static final String name = "name";


    public static void writeBoolean(Context context, String key, boolean value) {
        getEditor(context).putBoolean(key, value).commit();
    }

    public static boolean readBoolean(Context context, String key,
            boolean defValue) {
        return getPreferences(context).getBoolean(key, defValue);
    }

    public static void writeInteger(Context context, String key, int value) {
        getEditor(context).putInt(key, value).commit();

    }

    public static int readInteger(Context context, String key, int defValue) {
        return getPreferences(context).getInt(key, defValue);
    }

    public static void writeString(Context context, String key, String value) {
        getEditor(context).putString(key, value).commit();

    }

    public static String readString(Context context, String key, String defValue) {
        return getPreferences(context).getString(key, defValue);
    }

    public static void writeLong(Context context, String key, long value) {
        getEditor(context).putLong(key, value).commit();
    }

    public static long readLong(Context context, String key, long defValue) {
        return getPreferences(context).getLong(key, defValue);
    }

    public static SharedPreferences getPreferences(Context context) {
        return context.getSharedPreferences(PREF_NAME, MODE);
    }

    public static Editor getEditor(Context context) {
        return getPreferences(context).edit();
    }

}

Write the Value :

PreferenceConnector.writeString(this, PreferenceConnector.name,"Girish");

And Get value using :

String name= PreferenceConnector.readString(this, PreferenceConnector.name, "");

You may do this completely in-line by replacing the desired character with an empty string, calling LENGTH function and substracting from the original string's length.

SELECT 
  CustomerName, 
  LENGTH(CustomerName) -
  LENGTH(REPLACE(CustomerName, ' ', '')) AS NumberOfSpaces
FROM Customers;

Keycode 13 is the Enter key

Which keycode for escape key with jQuery

If the jar's in your classpath, and you know its Main class, you can just invoke the main class. Using DITA-OT as an example:

import org.dita.dost.invoker.CommandLineInvoker;
....
CommandLineInvoker.main('-f', 'html5', '-i', 'samples/sequence.ditamap', '-o', 'test')

Note this will make the subordinate jar share memory space and a classpath with your jar, with all the potential for interference that can cause. If you don't want that stuff polluted, you have other options, as mentioned above - namely:

• create a new ClassLoader with the jar in it. This is more safe; you can at least isolate the new jar's knowledge to a core classloader if you architect things with the knowledge that you'll be making use of alien jars. It's what we do in my shop for our plugins system; the main application is a tiny shell with a ClassLoader factory, a copy of the API, and knowledge that the real application is the first plugin for which it should build a ClassLoader. Plugins are a pair of jars - interface and implementation - that are zipped up together. The ClassLoaders all share all the interfaces, while each ClassLoader only has knowledge of its own implementation. The stack's a little complex, but it passes all tests and works beautifully.
• use Runtime.getRuntime.exec(...) (which wholly isolates the jar, but has the normal "find the application", "escape your strings right", "platform-specific WTF", and "OMG System Threads" pitfalls of running system commands.

In Kotlin I have created an extension function for the Context. It takes a @StringRes and optionally you can provide parameters as well.

fun Context.fromHtmlWithParams(@StringRes stringRes: Int, parameter : String? = null) : Spanned {

    val stringText = if (parameter.isNullOrEmpty()) {
                    this.getString(stringRes)
                } else {
                    this.getString(stringRes, parameter)
                }

    return Html.fromHtml(stringText, Html.FROM_HTML_MODE_LEGACY)

}

Usage

tv_directors.text = context?.fromHtmlWithParams(R.string.directors, movie.Director)

A very simple solution is to add the database name with your table name like if your DB name is DBMS and table is info then it will be DBMS.info for any query.

If your query is

select * from STUDENTREC where ROLL_NO=1;

it might show an error but

select * from DBMS.STUDENTREC where ROLL_NO=1; 

it doesn't because now actually your table is found.

Another solution is the following:

ISNULL(NULLIF(DATEPART(dw,DateField)-1,0),7)

While you can do that, insofar as it isn't explicitly precluded by the HTTP specification, I would suggest avoiding it simply because people don't expect things to work that way. There are many phases in an HTTP request chain and while they "mostly" conform to the HTTP spec, the only thing you're assured is that they will behave as traditionally used by web browsers. (I'm thinking of things like transparent proxies, accelerators, A/V toolkits, etc.)

This is the spirit behind the Robustness Principle roughly "be liberal in what you accept, and conservative in what you send", you don't want to push the boundaries of a specification without good reason.

However, if you have a good reason, go for it.

I'm guessing

x= data[:,0]
y= data[:,1]

In options object you have used "=" sign to assign value to port but we have to use ":" to assign values to properties in object when using object literal to create an object i.e."{}" ,these curly brackets. Even when you use function expression or create an object inside object you have to use ":" sign. for e.g.:

    var rishabh = {
        class:"final year",
        roll:123,
        percent: function(marks1, marks2, marks3){
                      total = marks1 + marks2 + marks3;
                      this.percentage = total/3 }
                    };

john.percent(85,89,95);
console.log(rishabh.percentage);

here we have to use commas "," after each property. but you can use another style to create and initialize an object.

var john = new Object():
john.father = "raja";  //1st way to assign using dot operator
john["mother"] = "rani";// 2nd way to assign using brackets and key must be string

Range("A10") = WorksheetFunction.Sum(Worksheets("Sheet1").Range("A1", "A9"))

Where

Range("A10") is the answer cell

Range("A1", "A9") is the range to calculate

Swift 2.0 you can initialize Integer using constructor

var stringNumber = "1234"
var numberFromString = Int(stringNumber)

In my case, I had a collection of radio buttons that needed to be in a group. I just included a 'Selected' property in the model. Then, in the loop to output the radiobuttons just do...

@Html.RadioButtonFor(m => Model.Selected, Model.Categories[i].Title)

This way, the name is the same for all radio buttons. When the form is posted, the 'Selected' property is equal to the category title (or id or whatever) and this can be used to update the binding on the relevant radiobutton, like this...

model.Categories.Find(m => m.Title.Equals(model.Selected)).Selected = true;

May not be the best way, but it does work.

You can use the Math.Max method to return the maximum of two numbers, e.g. for int:

int maximum = Math.Max(number1, Math.Max(number2, number3))

There ist also the Max() method from LINQ which you can use on any IEnumerable.

Try this. Works on both windows or linux server..

str_replace('\\','/',dirname(dirname(__FILE__)))

In my case, the database was related to an old Sharepoint install. Stopping and disabling related services in the server manager "unhung" the take offline action, which had been running for 40 minutes, and it completed immediately.

You may wish to check if any services are currently utilizing the database.

Alternative without using cut2.

das$wt2 <- as.factor( as.numeric( cut(das$wt,3)))

or

das$wt2 <- as.factor( cut(das$wt,3, labels=F))

As pointed out by @ben-bolker this splits into equal-widths rather occupancy. I think that using quantiles one can approximate equal-occupancy

x = rnorm(10)
x
 [1] -0.1074316  0.6690681 -1.7168853  0.5144931  1.6460280  0.7014368
 [7]  1.1170587 -0.8503069  0.4462932 -0.1089427
bin = 3 #for 1/3 rd, 4 for 1/4, 100 for 1/100th etc
xx = cut(x, quantile(x, breaks=1/bin*c(1:bin)), labels=F, include.lowest=T)
table(xx)
1 2 3 4
3 2 2 3

Simple, use array_intersect() instead:

$result = array_intersect($array1, $array2);

I installed python2.7 to solve this issue. I wish can help you.

On macOS High Sierra, this solved my issue:

Marco's answer above is correct, but just to expand on the question of "under what context"...

frame - this is the property you most often use for normal iPhone applications. most controls will be laid out relative to the "containing" control so the frame.origin will directly correspond to where the control needs to display, and frame.size will determine how big to make the control.

center - this is the property you will likely focus on for sprite based games and animations where movement or scaling may occur. By default animation and rotation will be based on the center of the UIView. It rarely makes sense to try and manage such objects by the frame property.

bounds - this property is not a positioning property, but defines the drawable area of the UIView "relative" to the frame. By default this property is usually (0, 0, width, height). Changing this property will allow you to draw outside of the frame or restrict drawing to a smaller area within the frame. A good discussion of this can be found at the link below. It is uncommon for this property to be manipulated unless there is specific need to adjust the drawing region. The only exception is that most programs will use the [[UIScreen mainScreen] bounds] on startup to determine the visible area for the application and setup their initial UIView's frame accordingly.

Why is there an frame rectangle and an bounds rectangle in an UIView?

Hopefully this helps clarify the circumstances where each property might get used.

In C# 6:

It is now possible to declare the auto-properties just as a field:

public string FirstName { get; set; } = "Ropert";

Read-Only Auto-Properties

public string FirstName { get;} = "Ropert";

In my Python 2.7 interpreter, the same whos command that exists in MATLAB exists in Python. It shows the same details as the MATLAB analog (variable name, type, and value/data).

Note that in the Python interpreter, whos lists all variables in the "interactive namespace".

How about custom module based .htaccess script (like its used in CodeIgniter)? I tried and it worked good in CodeIgniter apps. Any ideas to use it on other apps?

<IfModule authz_core_module>
    Require all denied
</IfModule>
<IfModule !authz_core_module>
    Deny from all
</IfModule>

NOTE

For Android Studio 0.5.5 and later, and with later versions of the Facebook SDK, this process is much simpler than what is documented below (which was written for earlier versions of both). If you're running the latest, all you need to do is this:

1. Download the Facebook SDK from https://developers.facebook.com/docs/android/
2. Unzip the archive
3. In Android Studio 0.5.5 or later, choose "Import Module" from the File menu.
4. In the wizard, set the source path of the module to import as the "facebook" directory inside the unpacked archive. (Note: If you choose the entire parent folder, it will bring in not only the library itself, but also all of the sample apps, each as a separate module. This may work but probably isn't what you want).
5. Open project structure by Ctrl + Shift + Alt + S and then select dependencies tab. Click on + button and select Module Dependency. In the new window pop up select :facebook.
6. You should be good to go.

Instructions for older Android Studio and older Facebook SDK

This applies to Android Studio 0.5.4 and earlier, and makes the most sense for versions of the Facebook SDK before Facebook offered Gradle build files for the distribution. I don't know in which version of the SDK they made that change.

Facebook's instructions under "Import the SDK into an Android Studio Project" on their https://developers.facebook.com/docs/getting-started/facebook-sdk-for-android-using-android-studio/3.0/ page are wrong for Gradle-based projects (i.e. your project was built using Android Studio's New Project wizard and/or has a build.gradle file for your application module). Follow these instructions instead:

1. Create a libraries folder underneath your project's main directory. For example, if your project is HelloWorldProject, you would create a HelloWorldProject/libraries folder.

2. Now copy the entire facebook directory from the SDK installation into the libraries folder you just created.

3. Delete the libs folder in the facebook directory. If you like, delete the project.properties, build.xml, .classpath, and .project. files as well. You don't need them.

4. Create a build.gradle file in the facebook directory with the following contents:

   buildscript {
       repositories {
           mavenCentral()
       }
       dependencies {
           classpath 'com.android.tools.build:gradle:0.6.+'
       }
   }
   
   apply plugin: 'android-library'
   
   dependencies {
       compile 'com.android.support:support-v4:+'
   }
   
   android {
       compileSdkVersion 17
       buildToolsVersion "19.0.0"
   
       defaultConfig {
           minSdkVersion 7
           targetSdkVersion 16
       }
   
       sourceSets {
           main {
               manifest.srcFile 'AndroidManifest.xml'
               java.srcDirs = ['src']
               resources.srcDirs = ['src']
               res.srcDirs = ['res']
           }
       }
   }
   

   Note that depending on when you're following these instructions compared to when this is written, you may need to adjust the classpath 'com.android.tools.build:gradle:0.6.+' line to reference a newer version of the Gradle plugin. Soon we will require version 0.7 or later. Try it out, and if you get an error that a newer version of the Gradle plugin is required, that's the line you have to edit.

5. Make sure the Android Support Library in your SDK manager is installed.

6. Edit your settings.gradle file in your application’s main directory and add this line:

   include ':libraries:facebook'
   

7. If your project is already open in Android Studio, click the "Sync Project with Gradle Files" button in the toolbar. Once it's done, the facebook module should appear.

8. Open the Project Structure dialog. Choose Modules from the left-hand list, click on your application’s module, click on the Dependencies tab, and click on the + button to add a new dependency.
9. Choose “Module dependency”. It will bring up a dialog with a list of modules to choose from; select “:libraries:facebook”.
10. Click OK on all the dialogs. Android Studio will automatically resynchronize your project (making it unnecessary to click that "Sync Project with Gradle Files" button again) and pick up the new dependency. You should be good to go.

if ($string =~ m/something/) {
   # Do work
}

Where something is a regular expression.

Change the definition of multiply to take additional unknown arguments:

multiply <- function(a, b, ...) {
  # Original code
}

Execute the following command:

git pull origin master --allow-unrelated-histories

A merge vim will open. Add some merging message and:

1. Press ESC
2. Press Shift + ';'
3. Press 'w' and then press 'q'.

And you are good to go.

Solved my own problem. This line:

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));

needs to be:

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), "UTF-8"));

or since Java 7:

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), StandardCharsets.UTF_8));

Reading the documentation, there is a way to pop the back stack based on either the transaction name or the id provided by commit. Using the name may be easier since it shouldn't require keeping track of a number that may change and reinforces the "unique back stack entry" logic.

Since you want only one back stack entry per Fragment, make the back state name the Fragment's class name (via getClass().getName()). Then when replacing a Fragment, use the popBackStackImmediate() method. If it returns true, it means there is an instance of the Fragment in the back stack. If not, actually execute the Fragment replacement logic.

private void replaceFragment (Fragment fragment){
  String backStateName = fragment.getClass().getName();

  FragmentManager manager = getSupportFragmentManager();
  boolean fragmentPopped = manager.popBackStackImmediate (backStateName, 0);

  if (!fragmentPopped){ //fragment not in back stack, create it.
    FragmentTransaction ft = manager.beginTransaction();
    ft.replace(R.id.content_frame, fragment);
    ft.addToBackStack(backStateName);
    ft.commit();
  }
}

EDIT

The problem is - when i launch A and then B, then press back button, B is removed and A is resumed. and pressing again back button should exit the app. But it is showing a blank window and need another press to close it.

This is because the FragmentTransaction is being added to the back stack to ensure that we can pop the fragments on top later. A quick fix for this is overriding onBackPressed() and finishing the Activity if the back stack contains only 1 Fragment

@Override
public void onBackPressed(){
  if (getSupportFragmentManager().getBackStackEntryCount() == 1){
    finish();
  }
  else {
    super.onBackPressed();
  }
}

Regarding the duplicate back stack entries, your conditional statement that replaces the fragment if it hasn't been popped is clearly different than what my original code snippet's. What you are doing is adding to the back stack regardless of whether or not the back stack was popped.

Something like this should be closer to what you want:

private void replaceFragment (Fragment fragment){
  String backStateName =  fragment.getClass().getName();
  String fragmentTag = backStateName;

  FragmentManager manager = getSupportFragmentManager();
  boolean fragmentPopped = manager.popBackStackImmediate (backStateName, 0);

  if (!fragmentPopped && manager.findFragmentByTag(fragmentTag) == null){ //fragment not in back stack, create it.
    FragmentTransaction ft = manager.beginTransaction();
    ft.replace(R.id.content_frame, fragment, fragmentTag);
    ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
    ft.addToBackStack(backStateName);
    ft.commit();
  } 
}

The conditional was changed a bit since selecting the same fragment while it was visible also caused duplicate entries.

Implementation:

I highly suggest not taking the the updated replaceFragment() method apart like you did in your code. All the logic is contained in this method and moving parts around may cause problems.

This means you should copy the updated replaceFragment() method into your class then change

backStateName = fragmentName.getClass().getName();
fragmentPopped = manager.popBackStackImmediate(backStateName, 0);
if (!fragmentPopped) {
            ft.replace(R.id.content_frame, fragmentName);
}
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
ft.addToBackStack(backStateName);
ft.commit();

so it is simply

replaceFragment (fragmentName);

EDIT #2

To update the drawer when the back stack changes, make a method that accepts in a Fragment and compares the class names. If anything matches, change the title and selection. Also add an OnBackStackChangedListener and have it call your update method if there is a valid Fragment.

For example, in the Activity's onCreate(), add

getSupportFragmentManager().addOnBackStackChangedListener(new OnBackStackChangedListener() {

  @Override
  public void onBackStackChanged() {
    Fragment f = getSupportFragmentManager().findFragmentById(R.id.content_frame);
    if (f != null){
      updateTitleAndDrawer (f);
    }

  }
});

And the other method:

private void updateTitleAndDrawer (Fragment fragment){
  String fragClassName = fragment.getClass().getName();

  if (fragClassName.equals(A.class.getName())){
    setTitle ("A");
    //set selected item position, etc
  }
  else if (fragClassName.equals(B.class.getName())){
    setTitle ("B");
    //set selected item position, etc
  }
  else if (fragClassName.equals(C.class.getName())){
    setTitle ("C");
    //set selected item position, etc
  }
}

Now, whenever the back stack changes, the title and checked position will reflect the visible Fragment.

clearfix should contain the floating elements but in your html you have added clearfix only after floating right that is your pull-right so you should do like this:

<div class="clearfix">
  <div id="sidebar">
    <ul>
      <li>A</li>
      <li>A</li>
      <li>C</li>
      <li>D</li>
      <li>E</li>
      <li>F</li>
      <li>...</li>
      <li>Z</li>
    </ul>
  </div>
  <div id="main">
    <div>
      <div class="pull-right">
        <a>RIGHT</a>
      </div>
    </div>
  <div>MOVED BELOW Z</div>
</div>

see this demo

Happy to know you solved the problem by setting overflow properties. However this is also good idea to clear the float. Where you have floated your elements you could add overflow: hidden; as you have done in your main.

Why do you all suggest heavy scope operations? I don't see why this is not an "angular" solution:

.directive('changeClassOnScroll', function ($window) {
  return {
    restrict: 'A',
    scope: {
        offset: "@",
        scrollClass: "@"
    },
    link: function(scope, element) {
        angular.element($window).bind("scroll", function() {
            if (this.pageYOffset >= parseInt(scope.offset)) {
                element.addClass(scope.scrollClass);
            } else {
                element.removeClass(scope.scrollClass);
            }
        });
    }
  };
})

So you can use it like this:

<navbar change-class-on-scroll offset="500" scroll-class="you-have-scrolled-down"></navbar>

or

<div change-class-on-scroll offset="500" scroll-class="you-have-scrolled-down"></div>

• Does not matter for inner joins

• Matters for outer joins

  a. WHERE clause: After joining. Records will be filtered after join has taken place.

  b. ON clause - Before joining. Records (from right table) will be filtered before joining. This may end up as null in the result (since OUTER join).

Example: Consider the below tables:

    1. documents:
     | id    | name        |
     --------|-------------|
     | 1     | Document1   |
     | 2     | Document2   |
     | 3     | Document3   |
     | 4     | Document4   |
     | 5     | Document5   |


    2. downloads:
     | id   | document_id   | username |
     |------|---------------|----------|
     | 1    | 1             | sandeep  |
     | 2    | 1             | simi     |
     | 3    | 2             | sandeep  |
     | 4    | 2             | reya     |
     | 5    | 3             | simi     |

a) Inside WHERE clause:

  SELECT documents.name, downloads.id
    FROM documents
    LEFT OUTER JOIN downloads
      ON documents.id = downloads.document_id
    WHERE username = 'sandeep'

 For above query the intermediate join table will look like this.

    | id(from documents) | name         | id (from downloads) | document_id | username |
    |--------------------|--------------|---------------------|-------------|----------|
    | 1                  | Document1    | 1                   | 1           | sandeep  |
    | 1                  | Document1    | 2                   | 1           | simi     |
    | 2                  | Document2    | 3                   | 2           | sandeep  |
    | 2                  | Document2    | 4                   | 2           | reya     |
    | 3                  | Document3    | 5                   | 3           | simi     |
    | 4                  | Document4    | NULL                | NULL        | NULL     |
    | 5                  | Document5    | NULL                | NULL        | NULL     |

  After applying the `WHERE` clause and selecting the listed attributes, the result will be: 

   | name         | id |
   |--------------|----|
   | Document1    | 1  |
   | Document2    | 3  | 

b) Inside JOIN clause

  SELECT documents.name, downloads.id
  FROM documents
    LEFT OUTER JOIN downloads
      ON documents.id = downloads.document_id
        AND username = 'sandeep'

For above query the intermediate join table will look like this.

    | id(from documents) | name         | id (from downloads) | document_id | username |
    |--------------------|--------------|---------------------|-------------|----------|
    | 1                  | Document1    | 1                   | 1           | sandeep  |
    | 2                  | Document2    | 3                   | 2           | sandeep  |
    | 3                  | Document3    | NULL                | NULL        | NULL     |
    | 4                  | Document4    | NULL                | NULL        | NULL     |
    | 5                  | Document5    | NULL                | NULL        | NULL     |

Notice how the rows in `documents` that did not match both the conditions are populated with `NULL` values.

After Selecting the listed attributes, the result will be: 

   | name       | id   |
   |------------|------|
   |  Document1 | 1    |
   |  Document2 | 3    | 
   |  Document3 | NULL |
   |  Document4 | NULL | 
   |  Document5 | NULL | 

/bla/a[contains(@prop, "foo")]

In short, the goal of __repr__ is to be unambiguous and __str__ is to be readable.

Here is a good example:

>>> import datetime
>>> today = datetime.datetime.now()
>>> str(today)
'2012-03-14 09:21:58.130922'
>>> repr(today)
'datetime.datetime(2012, 3, 14, 9, 21, 58, 130922)'

Read this documentation for repr:

repr(object)

Return a string containing a printable representation of an object. This is the same value yielded by conversions (reverse quotes). It is sometimes useful to be able to access this operation as an ordinary function. For many types, this function makes an attempt to return a string that would yield an object with the same value when passed to eval(), otherwise the representation is a string enclosed in angle brackets that contains the name of the type of the object together with additional information often including the name and address of the object. A class can control what this function returns for its instances by defining a __repr__() method.

Here is the documentation for str:

str(object='')

Return a string containing a nicely printable representation of an object. For strings, this returns the string itself. The difference with repr(object) is that str(object) does not always attempt to return a string that is acceptable to eval(); its goal is to return a printable string. If no argument is given, returns the empty string, ''.

If an element has multiples classes "[class^='apple-']" dosen't work, e.g.

<div class="fruits apple-monkey"></div>

Also make sure that you have allowed codeigniter to log the type of messages you want in a config file.

i.e $config['log_threshold'] = [log_level ranges 0-4];

If you need to perform this List.contains(Object with field value equal to x) repeatedly, a simple and efficient workaround would be:

List<field obj type> fieldOfInterestValues = new ArrayList<field obj type>;
for(Object obj : List) {
    fieldOfInterestValues.add(obj.getFieldOfInterest());
}

Then the List.contains(Object with field value equal to x) would be have the same result as fieldOfInterestValues.contains(x);

The transient keyword in Java is used to indicate that a field should not be part of the serialization (which means saved, like to a file) process.

From the Java Language Specification, Java SE 7 Edition, Section 8.3.1.3. transient Fields:

Variables may be marked transient to indicate that they are not part of the persistent state of an object.

For example, you may have fields that are derived from other fields, and should only be done so programmatically, rather than having the state be persisted via serialization.

Here's a GalleryImage class which contains an image and a thumbnail derived from the image:

class GalleryImage implements Serializable
{
    private Image image;
    private transient Image thumbnailImage;

    private void generateThumbnail()
    {
        // Generate thumbnail.
    }

    private void readObject(ObjectInputStream inputStream)
            throws IOException, ClassNotFoundException
    {
        inputStream.defaultReadObject();
        generateThumbnail();
    }    
}

In this example, the thumbnailImage is a thumbnail image that is generated by invoking the generateThumbnail method.

The thumbnailImage field is marked as transient, so only the original image is serialized rather than persisting both the original image and the thumbnail image. This means that less storage would be needed to save the serialized object. (Of course, this may or may not be desirable depending on the requirements of the system -- this is just an example.)

At the time of deserialization, the readObject method is called to perform any operations necessary to restore the state of the object back to the state at which the serialization occurred. Here, the thumbnail needs to be generated, so the readObject method is overridden so that the thumbnail will be generated by calling the generateThumbnail method.

For additional information, the Discover the secrets of the Java Serialization API article (which was originally available on the Sun Developer Network) has a section which discusses the use of and presents a scenario where the transient keyword is used to prevent serialization of certain fields.

Just change the mime type to: type="audio/mpeg", this way chrome will honor the autostart="false" parameter.

In addition to the above answers to exemplify invocation order, a simple run example

class myclass:
    def __init__(self):
        print("__init__")

    def __enter__(self): 
        print("__enter__")

    def __exit__(self, type, value, traceback):
        print("__exit__")

    def __del__(self):
        print("__del__")

with myclass(): 
    print("body")

Produces the output:

__init__
__enter__
body
__exit__
__del__

A reminder: when using the syntax with myclass() as mc, variable mc gets the value returned by __enter__(), in the above case None! For such use, need to define return value, such as:

def __enter__(self): 
    print('__enter__')
    return self

Try using:

ActionBar ab = getSupportActionBar();
ab.setHomeButtonEnabled(true);
ab.setDisplayUseLogoEnabled(true);
ab.setLogo(R.drawable.ic_launcher);

You can also try this: Go to the path where Python is installed in your system. For me it was something like C:\Users\\Local Settings\Application Data\Programs\Python\Python37 In this folder, you'll find a python executable. Just create a duplicate and rename it to python3. Works every time.

export default is used to export a single class, function or primitive from a script file.

The export can also be written as

export default function SafeString(string) {
  this.string = string;
}

SafeString.prototype.toString = function() {
  return "" + this.string;
};

This is used to import this function in another script file

Say in app.js, you can

import SafeString from './handlebars/safe-string';

A little about export

As the name says, it's used to export functions, objects, classes or expressions from script files or modules

Utiliites.js

export function cube(x) {
  return x * x * x;
}
export const foo = Math.PI + Math.SQRT2;

This can be imported and used as

App.js

import { cube, foo } from 'Utilities';
console.log(cube(3)); // 27
console.log(foo);    // 4.555806215962888

Or

import * as utilities from 'Utilities';
console.log(utilities.cube(3)); // 27
console.log(utilities.foo);    // 4.555806215962888

When export default is used, this is much simpler. Script files just exports one thing. cube.js

export default function cube(x) {
  return x * x * x;
};

and used as App.js

import Cube from 'cube';
console.log(Cube(3)); // 27

HTML:

<div id="my-div" class="hide">Hello, TB3</div>

Javascript:

$(function(){
    //If the HIDE class exists then remove it, But first hide DIV
    if ( $("#my-div").hasClass( 'hide' ) ) $("#my-div").hide().removeClass('hide');

    //Now, you can use any of these functions to display
    $("#my-div").show();
    //$("#my-div").fadeIn();
    //$("#my-div").toggle();
});

I ended up needing to replace 2017 with 2019, and everything worked fine. /shrug... no other suggestions here worked for me.

If you place image and css folder inside a parent directory suppose assets then the following code works perfectly. Either double quote or without a double quote both work fine.

body{_x000D_
   background: url("../image/bg.jpg");_x000D_
}

In other cases like if you call a class and try to put a background image in a particular location then you must mention height and width as well.

In short:

Abstraction is a technique that helps us identify which specific information is essential, and which information should be hidden.

Encapsulation is then the technique for enclosing the information in such a way to hide details and implementation details of an object.

This may not me a so good of a answer but if you first select all the files you want to access by pressing on them in the side bar, so that they pop up on top of your screen for example: script.js, index.html, style.css. Close all the files you don't need at the top.

When you're done with that you press Ctrl+B on windows and linux, i don't know what it is on mac.

But there you have it. please send no hate

Something like:

select t1.name, t2.image_id, t3.path
from table1 t1 inner join table2 t2 on t1.person_id = t2.person_id
inner join table3 t3 on t2.image_id=t3.image_id

You could also use the RouteHandler mixin to avoid the wrapper component and more easily pass down the parent's state as props:

var Dashboard = require('./Dashboard');
var Comments = require('./Comments');
var RouteHandler = require('react-router/modules/mixins/RouteHandler');

var Index = React.createClass({
      mixins: [RouteHandler],
      render: function () {
        var handler = this.getRouteHandler({ myProp: 'value'});
        return (
            <div>
                <header>Some header</header>
                {handler}
           </div>
        );
  }
});

var routes = (
  <Route path="/" handler={Index}>
    <Route path="comments" handler={Comments}/>
    <DefaultRoute handler={Dashboard}/>
  </Route>
);

ReactRouter.run(routes, function (Handler) {
  React.render(<Handler/>, document.body);
});

In Unix systems the end of a line is represented with a line feed (LF). In windows a line is represented with a carriage return (CR) and a line feed (LF) thus (CRLF). when you get code from git that was uploaded from a unix system they will only have an LF.

If you are a single developer working on a windows machine, and you don't care that git automatically replaces LFs to CRLFs, you can turn this warning off by typing the following in the git command line

git config core.autocrlf true

If you want to make an intelligent decision how git should handle this, read the documentation

Here is a snippet

Formatting and Whitespace

Formatting and whitespace issues are some of the more frustrating and subtle problems that many developers encounter when collaborating, especially cross-platform. It’s very easy for patches or other collaborated work to introduce subtle whitespace changes because editors silently introduce them, and if your files ever touch a Windows system, their line endings might be replaced. Git has a few configuration options to help with these issues.

core.autocrlf

If you’re programming on Windows and working with people who are not (or vice-versa), you’ll probably run into line-ending issues at some point. This is because Windows uses both a carriage-return character and a linefeed character for newlines in its files, whereas Mac and Linux systems use only the linefeed character. This is a subtle but incredibly annoying fact of cross-platform work; many editors on Windows silently replace existing LF-style line endings with CRLF, or insert both line-ending characters when the user hits the enter key.

Git can handle this by auto-converting CRLF line endings into LF when you add a file to the index, and vice versa when it checks out code onto your filesystem. You can turn on this functionality with the core.autocrlf setting. If you’re on a Windows machine, set it to true – this converts LF endings into CRLF when you check out code:

$ git config --global core.autocrlf true

If you’re on a Linux or Mac system that uses LF line endings, then you don’t want Git to automatically convert them when you check out files; however, if a file with CRLF endings accidentally gets introduced, then you may want Git to fix it. You can tell Git to convert CRLF to LF on commit but not the other way around by setting core.autocrlf to input:

$ git config --global core.autocrlf input

This setup should leave you with CRLF endings in Windows checkouts, but LF endings on Mac and Linux systems and in the repository.

If you’re a Windows programmer doing a Windows-only project, then you can turn off this functionality, recording the carriage returns in the repository by setting the config value to false:

$ git config --global core.autocrlf false

select RTRIM(A.FIELD) from SCHEMA.TABLE A where RTRIM(A.FIELD) =  ('10544175A') 
 UNION  
select RTRIM(A.FIELD) from SCHEMA.TABLE A where RTRIM(A.FIELD) = ('10328189B') 
 UNION  
select RTRIM(A.FIELD) from SCHEMA.TABLE A where RTRIM(A.FIELD) = ('103498732H')

This worked to me.

git config --global http.proxy proxy_user:proxy_passwd@proxy_ip:proxy_port

First thing, you don't need to write

ResultSet rs = stmt.executeQuery(sql);

just write

ResultSet rs = stmt.executeQuery();

The above mentioned syntax is used for Statements not for PreparedStatement.

Second thing, rs.next() checks if the result set contains any values or not. It returns a boolean value as well as it moves the cursor to the first value in the result set because initially it is at BEFORE FIRST Position. So if you want to access first value in result set, you need to write rs.next().

Use a class method:

def self.colours
  ['white', 'red', 'black']
end

Then Model.colours will return that array. Alternatively, create an initializer and wrap the constants in a module to avoid namespace conflicts.

JSONObject responseDetailsJson = new JSONObject();
JSONArray jsonArray = new JSONArray();

List<String> ls =new  ArrayList<String>();

for(product cj:cities.getList()) {
    ls.add(cj);
    JSONObject formDetailsJson = new JSONObject();
    formDetailsJson.put("id", cj.id);
    formDetailsJson.put("name", cj.name);
    jsonArray.put(formDetailsJson);
}

responseDetailsJson.put("Cities", jsonArray);

return responseDetailsJson;

short answer - add following line in the jsp which will define the base
base href="/{root of your application}/"

I use fetchObject() here a small example using Symfony 4.4

    <?php 
    use Doctrine\DBAL\Driver\Connection;

    class MyController{

    public function index($username){
      $queryBuilder = $connection->createQueryBuilder();
      $queryBuilder
        ->select('id', 'name')
        ->from('app_user')
        ->where('name = ?')
        ->setParameter(0, $username)
        ->setMaxResults(1);
      $stmUser = $queryBuilder->execute();

      dump($stmUser->fetchObject());

      //get_class_methods($stmUser) -> to see all methods
    }
  }

Response:

{ 
"id": "2", "name":"myuser"
}

Below Test Init will also do the job.

[TestInitialize]
public void TestInit()
{
  HttpContext.Current = new HttpContext(new HttpRequest(null, "http://tempuri.org", null), new HttpResponse(null));
  YourControllerToBeTestedController = GetYourToBeTestedController();
}

When your view loads, so does its associated controller. Instead of using ng-init, simply call your init() method in your controller:

$scope.init = function () {
    if ($routeParams.Id) {
        //get an existing object
    } else {
        //create a new object
    }
    $scope.isSaving = false;
}
...
$scope.init();

Since your controller runs before ng-init, this also solves your second issue.

Fiddle

As John David Five mentioned, you might not want to attach this to $scope in order to make this method private.

var init = function () {
    // do something
}
...
init();

See jsFiddle

If you want to wait for certain data to be preset, either move that data request to a resolve or add a watcher to that collection or object and call your init method when your data meets your init criteria. I usually remove the watcher once my data requirements are met so the init function doesnt randomly re-run if the data your watching changes and meets your criteria to run your init method.

var init = function () {
    // do something
}
...
var unwatch = scope.$watch('myCollecitonOrObject', function(newVal, oldVal){
                    if( newVal && newVal.length > 0) {
                        unwatch();
                        init();
                    }
                });

If you are creating a mock-up with SoapUI,a free testing tool for REST and SOAP request and response, for Angular 2+ application you should remember to set inside your http header request

 Access-Control-Allow-Origin :  *

I add two images for helping your insert. The first shows the header you should add. If you want to add the header before you have to click the plus button(it's green).

The second image shows the insert the *. The value * permits to accept all the request from different hosts.

After this work my Angular application removed this annoying error in my console.

A big recourse that helped me to understand for creating my first mock up is this video. It will help you for creating a new mock-up inside SoapUi's environment without a server-side.

could also use following as per the php manual comment

$_SERVER['REDIRECT_URL']

Please note this is working only for certain PHP environment only and follow the bellow comment from that page for more information;

Purpose: The URL path name of the current PHP file, path-info is N/A and excluding URL query string. Includes leading slash.

Caveat: This is before URL rewrites (i.e. it's as per the original call URL).

Caveat: Not set on all PHP environments, and definitely only ones with URL rewrites.

Works on web mode: Yes

Works on CLI mode: No

Are you calling the web service from client script or on the server side?

You may find sending a content type header to the server will help, e.g.

'application/json; charset=utf-8'

On the client side, I use prototype client side library and there is a contentType parameter when making an Ajax call where you can specify this. I think jQuery has a getJSON method.

This will give you the deadline :

select id,  
       title,
       created_at + interval '1' day * claim_window as deadline
from projects

Alternatively the function make_interval can be used:

select id,  
       title,
       created_at + make_interval(days => claim_window) as deadline
from projects

To get all projects where the deadline is over, use:

select *
from (
  select id, 
         created_at + interval '1' day * claim_window as deadline
  from projects
) t
where localtimestamp at time zone 'UTC' > deadline

Move File or Folder:

public static void moveFile(File srcFileOrDirectory, File desFileOrDirectory) throws IOException {
    File newFile = new File(desFileOrDirectory, srcFileOrDirectory.getName());
    try (FileChannel outputChannel = new FileOutputStream(newFile).getChannel(); FileChannel inputChannel = new FileInputStream(srcFileOrDirectory).getChannel()) {
        inputChannel.transferTo(0, inputChannel.size(), outputChannel);
        inputChannel.close();
        deleteRecursive(srcFileOrDirectory);
    }
}

private static void deleteRecursive(File fileOrDirectory) {
    if (fileOrDirectory.isDirectory())
        for (File child : Objects.requireNonNull(fileOrDirectory.listFiles()))
            deleteRecursive(child);
    fileOrDirectory.delete();
}

Here's a variation I had to solve that's worth sharing: for each unique string in columnA I wanted to find the most common associated string in columnB.

df.groupby('columnA').agg({'columnB': lambda x: x.mode().any()}).reset_index()

The .any() picks one if there's a tie for the mode. (Note that using .any() on a Series of ints returns a boolean rather than picking one of them.)

For the original question, the corresponding approach simplifies to

df.groupby('columnA').columnB.agg('max').reset_index().

Only use Popen kill method

process = subprocess.Popen(
    task.getExecutable(), 
    stdout=subprocess.PIPE, 
    stderr=subprocess.PIPE, 
    shell=True
)
process.kill()

1. typedef is used to alias types; in this case you're aliasing FunctionFunc to void(*)().

2. Indeed the syntax does look odd, have a look at this:

   typedef   void      (*FunctionFunc)  ( );
   //         ^                ^         ^
   //     return type      type name  arguments
   

3. No, this simply tells the compiler that the FunctionFunc type will be a function pointer, it doesn't define one, like this:

   FunctionFunc x;
   void doSomething() { printf("Hello there\n"); }
   x = &doSomething;
   
   x(); //prints "Hello there"
   

Try this

q = Session.query(
         User, Document, DocumentPermissions,
    ).filter(
         User.email == Document.author,
    ).filter(
         Document.name == DocumentPermissions.document,
    ).filter(
        User.email == 'someemail',
    ).all()

Provided that you are extending JFrame:

public void run() {
    MyFrame myFrame = new MyFrame();
    myFrame.setVisible(true);
    myFrame.setExtendedState(myFrame.getExtendedState() | JFrame.MAXIMIZED_BOTH);
}

Unfortunately, np.polynomial.polynomial.polyfit returns the coefficients in the opposite order of that for np.polyfit and np.polyval (or, as you used np.poly1d). To illustrate:

In [40]: np.polynomial.polynomial.polyfit(x, y, 4)
Out[40]: 
array([  84.29340848, -100.53595376,   44.83281408,   -8.85931101,
          0.65459882])

In [41]: np.polyfit(x, y, 4)
Out[41]: 
array([   0.65459882,   -8.859311  ,   44.83281407, -100.53595375,
         84.29340846])

In general: np.polynomial.polynomial.polyfit returns coefficients [A, B, C] to A + Bx + Cx^2 + ..., while np.polyfit returns: ... + Ax^2 + Bx + C.

So if you want to use this combination of functions, you must reverse the order of coefficients, as in:

ffit = np.polyval(coefs[::-1], x_new)

However, the documentation states clearly to avoid np.polyfit, np.polyval, and np.poly1d, and instead to use only the new(er) package.

You're safest to use only the polynomial package:

import numpy.polynomial.polynomial as poly

coefs = poly.polyfit(x, y, 4)
ffit = poly.polyval(x_new, coefs)
plt.plot(x_new, ffit)

Or, to create the polynomial function:

ffit = poly.Polynomial(coefs)    # instead of np.poly1d
plt.plot(x_new, ffit(x_new))

Recently when working on a web app for a client, I noticed that any click events added to a non-anchor element didn't work on the iPad or iPhone. All desktop and other mobile devices worked fine - but as the Apple products are the most popular mobile devices, it was important to get it fixed.

Turns out that any non-anchor element assigned a click handler in jQuery must either have an onClick attribute (can be empty like below):

onClick=""

OR

The element css needs to have the following declaration:

cursor:pointer

Strange, but that's what it took to get things working again!

This blog post explains it perfectly: Ruby's Exception vs StandardError: What's the difference?

Why you shouldn't rescue Exception

The problem with rescuing Exception is that it actually rescues every exception that inherits from Exception. Which is....all of them!

That's a problem because there are some exceptions that are used internally by Ruby. They don't have anything to do with your app, and swallowing them will cause bad things to happen.

Here are a few of the big ones:

• SignalException::Interrupt - If you rescue this, you can't exit your app by hitting control-c.

• ScriptError::SyntaxError - Swallowing syntax errors means that things like puts("Forgot something) will fail silently.

• NoMemoryError - Wanna know what happens when your program keeps running after it uses up all the RAM? Me neither.

begin
  do_something()
rescue Exception => e
  # Don't do this. This will swallow every single exception. Nothing gets past it. 
end

I'm guessing that you don't really want to swallow any of these system-level exceptions. You only want to catch all of your application level errors. The exceptions caused YOUR code.

Luckily, there's an easy way to to this.

Rescue StandardError Instead

All of the exceptions that you should care about inherit from StandardError. These are our old friends:

NoMethodError - raised when you try to invoke a method that doesn't exist

TypeError - caused by things like 1 + ""

RuntimeError - who could forget good old RuntimeError?

To rescue errors like these, you'll want to rescue StandardError. You COULD do it by writing something like this:

begin
  do_something()
rescue StandardError => e
  # Only your app's exceptions are swallowed. Things like SyntaxErrror are left alone. 
end

But Ruby has made it much easier for use.

When you don't specify an exception class at all, ruby assumes you mean StandardError. So the code below is identical to the above code:

begin
  do_something()
rescue => e
  # This is the same as rescuing StandardError
end

In case you want to keep things simple without resorting to CSS, I just put a   in my code lines. I.e., <table></table>.

Yeah, it leaves a few spaces, but that's not a bad thing.

I'll show you three ways to (a) get the minute field from a long value, and (b) print it using the Date format you want. One uses java.util.Calendar, another uses Joda-Time, and the last uses the java.time framework built into Java 8 and later.

The java.time framework supplants the old bundled date-time classes, and is inspired by Joda-Time, defined by JSR 310, and extended by the ThreeTen-Extra project.

The java.time framework is the way to go when using Java 8 and later. Otherwise, such as Android, use Joda-Time. The java.util.Date/.Calendar classes are notoriously troublesome and should be avoided.

java.util.Date & .Calendar

final long timestamp = new Date().getTime();

// with java.util.Date/Calendar api
final Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(timestamp);
// here's how to get the minutes
final int minutes = cal.get(Calendar.MINUTE);
// and here's how to get the String representation
final String timeString =
    new SimpleDateFormat("HH:mm:ss:SSS").format(cal.getTime());
System.out.println(minutes);
System.out.println(timeString);

Joda-Time

// with JodaTime 2.4
final DateTime dt = new DateTime(timestamp);
// here's how to get the minutes
final int minutes2 = dt.getMinuteOfHour();
// and here's how to get the String representation
final String timeString2 = dt.toString("HH:mm:ss:SSS");
System.out.println(minutes2);
System.out.println(timeString2);

Output:

24
09:24:10:254
24
09:24:10:254

java.time

long millisecondsSinceEpoch = 1289375173771L;
Instant instant = Instant.ofEpochMilli ( millisecondsSinceEpoch );
ZonedDateTime zdt = ZonedDateTime.ofInstant ( instant , ZoneOffset.UTC );

DateTimeFormatter formatter = DateTimeFormatter.ofPattern ( "HH:mm:ss:SSS" );
String output = formatter.format ( zdt );

System.out.println ( "millisecondsSinceEpoch: " + millisecondsSinceEpoch + " instant: " + instant + " output: " + output );

millisecondsSinceEpoch: 1289375173771 instant: 2010-11-10T07:46:13.771Z output: 07:46:13:771

Had to look it up in the specs:

• Class.getResource(String resource)

• ClassLoader.getResource(String resource)

Class's getResource() - documentation states the difference:

This method delegates the call to its class loader, after making these changes to the resource name: if the resource name starts with "/", it is unchanged; otherwise, the package name is prepended to the resource name after converting "." to "/". If this object was loaded by the bootstrap loader, the call is delegated to ClassLoader.getSystemResource.

result_array() returns Associative Array type data. Returning pure array is slightly faster than returning an array of objects. result() is recursive in that it returns an std class object where as result_array() just returns a pure array, so result_array() would be choice regarding performance.

I would use Winamp to do this. Create a playlist of files you want to merge into one, select Disk Writer output plugin, choose filename and you're done. The file you will get will be correct MP3 file and you can set bitrate etc.

I used to do a simple for loop. As @A5C1D2H2I1M1N2O1R2T1 answer, lapply is a nice solution. But if you convert all the columns, you will need a data.frame before, otherwise you will end up with a list. Little execution time differences.

"%f" is the (or at least one) correct format for a double. There is no format for a float, because if you attempt to pass a float to printf, it'll be promoted to double before printf receives it¹. "%lf" is also acceptable under the current standard -- the l is specified as having no effect if followed by the f conversion specifier (among others).

Note that this is one place that printf format strings differ substantially from scanf (and fscanf, etc.) format strings. For output, you're passing a value, which will be promoted from float to double when passed as a variadic parameter. For input you're passing a pointer, which is not promoted, so you have to tell scanf whether you want to read a float or a double, so for scanf, %f means you want to read a float and %lf means you want to read a double (and, for what it's worth, for a long double, you use %Lf for either printf or scanf).

_{1. C99, §6.5.2.2/6: "If the expression that denotes the called function has a type that does not include a prototype, the integer promotions are performed on each argument, and arguments that have type float are promoted to double. These are called the default argument promotions." In C++ the wording is somewhat different (e.g., it doesn't use the word "prototype") but the effect is the same: all the variadic parameters undergo default promotions before they're received by the function.}

Not exactly answering your question, but I came across your question, while looking for an answer to an issue that I had. Maybe it will help somebody else.

My issue was that cookies were set in server response, but were not saved by the browser.

The server response came back with cookies set:

Set-Cookie:my_cookie=HelloWorld; Path=/; Expires=Wed, 15 Mar 2017 15:59:59 GMT 

This is how I solved it.

I used fetch in the client-side code. If you do not specify credentials: 'include' in the fetch options, cookies are neither sent to server nor saved by the browser, even though the server response sets cookies.

Example:

var headers = new Headers();
headers.append('Content-Type', 'application/json');
headers.append('Accept', 'application/json');

return fetch('/your/server_endpoint', {
    method: 'POST',
    mode: 'same-origin',
    redirect: 'follow',
    credentials: 'include', // Don't forget to specify this if you need cookies
    headers: headers,
    body: JSON.stringify({
        first_name: 'John',
        last_name: 'Doe'
    })
})

I hope this helps somebody.

var x = document.getElementById("myTable").rows.length;

You can do something like this:

const base = {
  item1: { key: 'sdfd', value:'sdfd' },
  item2: { key: 'sdfd', value:'sdfd' },
  item3: { key: 'sdfd', value:'sdfd' }
};

const filtered = (
    source => { 
        with(source){ 
            return {item1, item3} 
        } 
    }
)(base);

// one line
const filtered = (source => { with(source){ return {item1, item3} } })(base);

This works but is not very clear, plus the with statement is not recommended (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/with).

If you really really need to use map function (like my class assignment here...), you could use a wrapper function with 1 argument, passing the rest to the original one in its body; i.e. :

extraArguments = value
def myFunc(arg):
    # call the target function
    return Func(arg, extraArguments)


map(myFunc, itterable)

Dirty & ugly, still does the trick

Change your code to:

int total=0, number=0;
float percentage=0.0f;

percentage=((float)number/total)*100f;
printf("%.2f", (double)percentage);

In case someone else ends up here struggling to customize admin form Many2Many saving behaviour, you can't call self.instance.my_m2m.add(obj) in your ModelForm.save override, as ModelForm.save later populates your m2m from self.cleaned_data['my_m2m'] which overwrites your changes. Instead call:

my_m2ms = list(self.cleaned_data['my_m2ms'])
my_m2ms.extend(my_custom_new_m2ms)
self.cleaned_data['my_m2ms'] = my_m2ms

(It is fine to convert the incoming QuerySet to a list - the ManyToManyField does that anyway.)

There is no performance difference.

A const_iterator is an iterator that points to const value (like a const T* pointer); dereferencing it returns a reference to a constant value (const T&) and prevents modification of the referenced value: it enforces const-correctness.

When you have a const reference to the container, you can only get a const_iterator.

Edited: I mentionned “The const_iterator returns constant pointers” which is not accurate, thanks to Brandon for pointing it out.

Edit: For COW objects, getting a non-const iterator (or dereferencing it) will probably trigger the copy. (Some obsolete and now disallowed implementations of std::string use COW.)

Try this, if you want to log to the active page's console:

chrome.tabs.executeScript({

This answer is an in-place QuickSort for Python 2.x. My answer is an interpretation of the in-place solution from Rosetta Code which works for Python 3 too:

import random

def qsort(xs, fst, lst):
    '''
    Sort the range xs[fst, lst] in-place with vanilla QuickSort

    :param xs:  the list of numbers to sort
    :param fst: the first index from xs to begin sorting from,
                must be in the range [0, len(xs))
    :param lst: the last index from xs to stop sorting at
                must be in the range [fst, len(xs))
    :return:    nothing, the side effect is that xs[fst, lst] is sorted
    '''
    if fst >= lst:
        return

    i, j = fst, lst
    pivot = xs[random.randint(fst, lst)]

    while i <= j:
        while xs[i] < pivot:
            i += 1
        while xs[j] > pivot:
            j -= 1

        if i <= j:
            xs[i], xs[j] = xs[j], xs[i]
            i, j = i + 1, j - 1
    qsort(xs, fst, j)
    qsort(xs, i, lst)

And if you are willing to forgo the in-place property, below is yet another version which better illustrates the basic ideas behind quicksort. Apart from readability, its other advantage is that it is stable (equal elements appear in the sorted list in the same order that they used to have in the unsorted list). This stability property does not hold with the less memory-hungry in-place implementation presented above.

def qsort(xs):
    if not xs: return xs # empty sequence case
    pivot = xs[random.choice(range(0, len(xs)))]

    head = qsort([x for x in xs if x < pivot])
    tail = qsort([x for x in xs if x > pivot])
    return head + [x for x in xs if x == pivot] + tail

Write the table name in the query editor select the name and press Alt+F1 and it will bring all the information of the table.

Shortly speaking, have you tried to check "Enable Bitcode=NO". It works for me.

In my case, my project was written in Object-C and includes one 3rd party framework written in swift. I can run my APP on both simulator and real device in developer mode. However, once I achieved the APP with Ad-hoc provision profile and installed this ipa OTA on real device, it crashed. Not even mention upload to store. Hope this information can help.

You listen to the onerror event by assigning a function to window.onerror:

 window.onerror = function (msg, url, lineNo, columnNo, error) {
        var string = msg.toLowerCase();
        var substring = "script error";
        if (string.indexOf(substring) > -1){
            alert('Script Error: See Browser Console for Detail');
        } else {
            alert(msg, url, lineNo, columnNo, error);
        }   
      return false; 
  };

For Unit Tests, the System variable is not instantiated yet when I do "mvn clean install" because there is no server running the application. So in order to set the System properties, I need to do it in pom.xml. Like so:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.21.0</version>
    <configuration>
        <systemPropertyVariables>
            <propertyName>propertyValue</propertyName>
            <MY_ENV_VAR>newValue</MY_ENV_VAR>
            <ENV_TARGET>olqa</ENV_TARGET>
            <buildDirectory>${project.build.directory}</buildDirectory>
        </systemPropertyVariables>
    </configuration>
</plugin>

This guy here => http://blog.stevenlevithan.com/archives/date-time-format wrote a format() function for the Javascript's Date object, so it can be used with familiar literal formats.

If you need full featured Date formatting in your app's Javascript, use it. Otherwise if what you want to do is a one off, then concatenating getYear(), getMonth(), getDay() is probably easiest.

I tried the answers, but in my case I did not get the raw output. Instead it was converted to a PowerShell exception.

The raw result I got with:

$rawOutput = (cmd /c <command> 2`>`&1)

Finally I got some answer, ::test::GTEST_FLAG(list_tests) = true; //From your program, not w.r.t console.

If you would like to use --gtest_filter =*; /* =*, =xyz*... etc*/ // You need to use them in Console.

So, my requirement is to use them from the program not from the console.

Updated:-

Finally I got the answer for updating the same in from the program.

 ::testing::GTEST_FLAG(filter) = "*Counter*:*IsPrime*:*ListenersTest.DoesNotLeak*";//":-:*Counter*";
      InitGoogleTest(&argc, argv);
RUN_ALL_TEST();

So, Thanks for all the answers.

You people are great.

My user account did not have the permissions to alter the database and table, as suggested in this solution.

If, like me, you don't care about the character collation (you are using the '=' operator), you can apply the reverse fix. Run this before your SELECT:

SET collation_connection = 'latin1_swedish_ci';

If you have a List<List<int>> k you can do

List<int> flatList= k.SelectMany( v => v).ToList();

DecimalFormat df=new DecimalFormat("0.00");

Use this code to get exact two decimal points. Even if the value is 0.0 it will give u 0.00 as output.

Instead if you use:

DecimalFormat df=new DecimalFormat("#.00");  

It wont convert 0.2659 into 0.27. You will get an answer like .27.

You can also do it at run time as follows :

• Assign name to the window (x:Name = "HomePage")
• In constructor just set WindowState property to Maximized as follows

HomePage.WindowState = WindowState.Maximized;

Could do this, but then the user has to separate the numbers by a space:

#include "stdio.h"

int main()
{
    int minx, x, y, z;

    printf("Enter four ints: ");
    scanf( "%i %i %i %i", &minx, &x, &y, &z);

    printf("You wrote: %i %i %i %i", minx, x, y, z);
}

let can also be used to avoid problems with closures. It binds fresh value rather than keeping an old reference as shown in examples below.

for(var i=1; i<6; i++) {_x000D_
  $("#div" + i).click(function () { console.log(i); });_x000D_
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<p>Clicking on each number will log to console:</p> _x000D_
<div id="div1">1</div>_x000D_
<div id="div2">2</div>_x000D_
<div id="div3">3</div>_x000D_
<div id="div4">4</div>_x000D_
<div id="div5">5</div>

Code above demonstrates a classic JavaScript closure problem. Reference to the i variable is being stored in the click handler closure, rather than the actual value of i.

Every single click handler will refer to the same object because there’s only one counter object which holds 6 so you get six on each click.

A general workaround is to wrap this in an anonymous function and pass i as an argument. Such issues can also be avoided now by using let instead var as shown in the code below.

_{(Tested in Chrome and Firefox 50)}

for(let i=1; i<6; i++) {_x000D_
  $("#div" + i).click(function () { console.log(i); });_x000D_
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_

There's some pretty good answers here but I want to elaborate on all topics:

Cloud: shailesh's answer is awesome, nothing to add there! Basically, An application that's served seamlessly over the network can be considered a Cloud application. Cloud isn't a new invention and it's very similar to Grid computing, but it's more of a buzzword with the spike of recent popularity.

Grid: Grid is defined as a large collection as machines connected by a private network and offers a set of services to users, it acts as a sort of supercomputer by sharing processing power across the machines. Source: Tenenbaum, Andrew.

Cluster: A cluster is different from those two. Clusters are two or more computers who share a network connection that acts as a heart-beat. Clusters are configurable in Active-Active or Active-Passive ways. Active-Active being that each computer runs it's own set of services (Say, one runs a SQL instance, the other runs a web server) and they share some resources such as storage. If one of the computers in a cluster goes down the service fails over to the other node and almost seamlessly starts running there. Active-Passive is similar, but only one machine runs these services and only takes over once there's a failure.

Is the Config/setup.php file actually in /test/content/home/ or is in your document root? it is best to make all references relative to your document root.

include $_SERVER['DOCUMENT_ROOT'] . "Config/setup.php";

Your current code assumes that the location of setup.php is in /text/content/home/Config/setup.php, is this correct?

This is the simplest wat to get the File object to which a certain URL object is pointing at:

File file=new File(url.toURI());

Now, for your concrete questions:

• finding all resources in the META-INF "directory":

You can indeed get the File object pointing to this URL

Enumeration<URL> en=getClass().getClassLoader().getResources("META-INF");
if (en.hasMoreElements()) {
    URL metaInf=en.nextElement();
    File fileMetaInf=new File(metaInf.toURI());

    File[] files=fileMetaInf.listFiles();
    //or 
    String[] filenames=fileMetaInf.list();
}

• all resources named bla.xml (recursivly)

In this case, you'll have to do some custom code. Here is a dummy example:

final List<File> foundFiles=new ArrayList<File>();

FileFilter customFilter=new FileFilter() {
    @Override
    public boolean accept(File pathname) {

        if(pathname.isDirectory()) {
            pathname.listFiles(this);
        }
        if(pathname.getName().endsWith("bla.xml")) {
            foundFiles.add(pathname);
            return true;
        }
        return false;
    }

};      
//rootFolder here represents a File Object pointing the root forlder of your search 
rootFolder.listFiles(customFilter);

When the code is run, you'll get all the found ocurrences at the foundFiles List.

The documentation for css() says that setting the style property to the empty string will remove that property if it does not reside in a stylesheet:

Setting the value of a style property to an empty string — e.g. $('#mydiv').css('color', '') — removes that property from an element if it has already been directly applied, whether in the HTML style attribute, through jQuery's .css() method, or through direct DOM manipulation of the style property. It does not, however, remove a style that has been applied with a CSS rule in a stylesheet or <style> element.

Since your styles are inline, you can write:

$(selector).css("-moz-user-select", "");

This may not be an option for you, but if you can use the Parallel Extension for .NET then you could use Tasks instead of raw threads and then use Task.WaitAll() to wait for them to complete.

You can't specify the width of an element with display inline. You could put something in it like a non-breaking space ( ) and then set the padding to give it some more width but you can't control it directly.

You could use display inline-block but that isn't widely supported.

A real hack would be to put an image inside and then set the width of that. Something like a transparent 1 pixel GIF. Not the recommended approach however.

Did you see this - http://kb.discountasp.net/KB/a799/error-accessing-wcf-service-this-collection-already.aspx

You can resolve this error by changing the web.config file.

With ASP.NET 4.0, add the following lines to your web.config:

<system.serviceModel> 
     <serviceHostingEnvironment multipleSiteBindingsEnabled="true" /> 
</system.serviceModel> 

With ASP.NET 2.0/3.0/3.5, add the following lines to your web.config:

<system.serviceModel> 
     <serviceHostingEnvironment> 
          <baseAddressPrefixFilters> 
               <add prefix="http://www.YourHostedDomainName.com"/> 
          </baseAddressPrefixFilters> 
     </serviceHostingEnvironment> 
</system.serviceModel> 

try:
    whatever()
except:
    # this will catch any exception or error

It is worth mentioning this is not proper Python coding. This will catch also many errors you might not want to catch.

Perhaps consider using a preprocessor macro definition instead:

#define UPDATE_ID(instance, id)  ({ (instance)->id= (id); })
#define UPDATE_ROUTE(instance, route)  ({ (instance)->route = (route); })
#define UPDATE_BACKUP_ROUTE(instance, route)  ({ (instance)->backup_route = (route); })
#define UPDATE_CURRENT_ROUTE(instance, route)  ({ (instance)->current_route = (route); })

If your instance of (struct foo) is global, then you don't need the parameter for that of course. But I'm assuming you probably have more than one instance. Using the ({ ... }) block is a GNU-ism that that applies to GCC; it is a nice (safe) way to keep lines together as a block. If you later need to add more to the macros, such as range validation checking, you won't have to worry about breaking things like if/else statements and so forth.

This is what I would do, based upon the requirements you indicated. Situations like this are one of the reasons that I started using python a lot; handling default parameters and such becomes a lot simpler than it ever is with C. (I guess that's a python plug, sorry ;-)

in order to know the phone resolution simply create a image with label mdpi, hdpi, xhdpi and xxhdpi. put these images in respective folder like mdpi, hdpi, xhdpi and xxhdpi. create a image view in layout and load this image. the phone will load the respective image from a specific folder. by this you will get the phone resolution or *dpi it is using.

>>> isinstance(3, int)
True

See here for more.

Note that this does not help if you're looking for int-like attributes. In this case you may also want to check for long:

>>> isinstance(3L, (long, int))
True

I've seen checks of this kind against an array/index type in the Python source, but I don't think that's visible outside of C.

Token SO reply: Are you sure you should be checking its type? Either don't pass a type you can't handle, or don't try to outsmart your potential code reusers, they may have a good reason not to pass an int to your function.

try {
} catch (javax.script.ScriptException ex) {

There is lots of information about the Fibonacci Sequence on wikipedia and on wolfram. A lot more than you may need. Anyway it is a good thing to learn how to use these resources to find (quickly if possible) what you need.

Write Fib sequence formula to infinite

In math, it's given in a recursive form:

In programming, infinite doesn't exist. You can use a recursive form translating the math form directly in your language, for example in Python it becomes:

def F(n):
    if n == 0: return 0
    elif n == 1: return 1
    else: return F(n-1)+F(n-2)

Try it in your favourite language and see that this form requires a lot of time as n gets bigger. In fact, this is O(2ⁿ) in time.

Go on on the sites I linked to you and will see this (on wolfram):

This one is pretty easy to implement and very, very fast to compute, in Python:

from math import sqrt
def F(n):
    return ((1+sqrt(5))**n-(1-sqrt(5))**n)/(2**n*sqrt(5))

An other way to do it is following the definition (from wikipedia):

The first number of the sequence is 0, the second number is 1, and each subsequent number is equal to the sum of the previous two numbers of the sequence itself, yielding the sequence 0, 1, 1, 2, 3, 5, 8, etc.

If your language supports iterators you may do something like:

def F():
    a,b = 0,1
    while True:
        yield a
        a, b = b, a + b

Display startNumber to endNumber only from Fib sequence.

Once you know how to generate Fibonacci Numbers you just have to cycle trough the numbers and check if they verify the given conditions.

Suppose now you wrote a f(n) that returns the n-th term of the Fibonacci Sequence (like the one with sqrt(5) )

In most languages you can do something like:

def SubFib(startNumber, endNumber):
    n = 0
    cur = f(n)
    while cur <= endNumber:
        if startNumber <= cur:
            print cur
        n += 1
        cur = f(n)

In python I'd use the iterator form and go for:

def SubFib(startNumber, endNumber):
    for cur in F():
        if cur > endNumber: return
        if cur >= startNumber:
            yield cur

for i in SubFib(10, 200):
    print i

My hint is to learn to read what you need. Project Euler (google for it) will train you to do so :P Good luck and have fun!

This is very simple you are trying to convert an integer to a list object !!! of course it will fail and it should ...

To demonstrate/prove this to you by using the example you provided ...just use type function for each case as below and the results will speak for itself !

>>> type(cow)
<class 'range'>
>>> 
>>> type(cow[0])
<class 'int'>
>>> 
>>> type(0)
<class 'int'>
>>> 
>>> >>> list(0)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not iterable
>>> 

I know this is a very old question but it may be that you need to set the request headers. This solved it for me.

For example 'user-agent', 'accept' etc. here is an example with user-agent:

url = 'your-url-here'
headers = {'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.75 Safari/537.36'}
r = requests.get(url, headers=headers)

What you have is on the right track.

def dosomething( thelist ):
    for element in thelist:
        print element

dosomething( ['1','2','3'] )
alist = ['red','green','blue']
dosomething( alist )  

Produces the output:

1
2
3
red
green
blue

A couple of things to note given your comment above: unlike in C-family languages, you often don't need to bother with tracking the index while iterating over a list, unless the index itself is important. If you really do need the index, though, you can use enumerate(list) to get index,element pairs, rather than doing the x in range(len(thelist)) dance.

In general, you need to use FormatMessage to convert from a Win32 error code to text.

From the MSDN documentation:

Formats a message string. The function requires a message definition as input. The message definition can come from a buffer passed into the function. It can come from a message table resource in an already-loaded module. Or the caller can ask the function to search the system's message table resource(s) for the message definition. The function finds the message definition in a message table resource based on a message identifier and a language identifier. The function copies the formatted message text to an output buffer, processing any embedded insert sequences if requested.

The declaration of FormatMessage:

DWORD WINAPI FormatMessage(
  __in      DWORD dwFlags,
  __in_opt  LPCVOID lpSource,
  __in      DWORD dwMessageId, // your error code
  __in      DWORD dwLanguageId,
  __out     LPTSTR lpBuffer,
  __in      DWORD nSize,
  __in_opt  va_list *Arguments
);

If you want to insert other string somewhere else in existing string, you may use selection method below.

Calling character on second position:

>>> s = "0123456789"
>>> s[2]
'2'

Calling range with start and end position:

>>> s[4:6]
'45'

Calling part of a string before that position:

>>> s[:6]
'012345'

Calling part of a string after that position:

>>> s[4:]
'456789'

Inserting your string in 5th position.

>>> s = s[:5] + "L" + s[5:]
>>> s
'01234L56789'

Also s is equivalent to s[:].

With your question you can use all your string, i.e.

>>> s = "L" + s + "LL"

or if "L" is a some other string (for example I call it as l), then you may use that code:

>>> s = l + s + (l * 2)

You can use FolderBrowserDialog instead of FileDialog and get the path from the OK result.

FolderBrowserDialog browser = new FolderBrowserDialog();
string tempPath ="";

if (browser.ShowDialog() == DialogResult.OK)
{
  tempPath  = browser.SelectedPath; // prints path
}

The list variable (which I would recommend to rename to something more sensible) is a reference to a list object, which can be changed.

On the line

listoflists.append((list, list[0]))

You actually are only adding a reference to the object reference by the list variable. You've got multiple possibilities to create a copy of the list, so listoflists contains the values as you seem to expect:

Use the copy library

import copy
listoflists.append((copy.copy(list), list[0]))

use the slice notation

listoflists.append((list[:], list[0]))

According to the Go specification:

For an expression x of interface type and a type T, the primary expression x.(T) asserts that x is not nil and that the value stored in x is of type T.

A "type assertion" allows you to declare an interface value contains a certain concrete type or that its concrete type satisfies another interface.

In your example, you were asserting data (type interface{}) has the concrete type string. If you are wrong, the program will panic at runtime. You do not need to worry about efficiency, checking just requires comparing two pointer values.

If you were unsure if it was a string or not, you could test using the two return syntax.

str, ok := data.(string)

If data is not a string, ok will be false. It is then common to wrap such a statement into an if statement like so:

if str, ok := data.(string); ok {
    /* act on str */
} else {
    /* not string */
}

There is a much easier way to get the smooth scroll effect without javascript. In your CSS just target the entire html tag and give it scroll-behavior: smooth;

html {_x000D_
  scroll-behavior: smooth;_x000D_
 }_x000D_
 _x000D_
 a {_x000D_
  text-decoration: none;_x000D_
  color: black;_x000D_
 } _x000D_
 _x000D_
 #down {_x000D_
  margin-top: 100%;_x000D_
  padding-bottom: 25%;_x000D_
 } 

<html>_x000D_
  <a href="#down">Click Here to Smoothly Scroll Down</a>_x000D_
  <div id="down">_x000D_
    <h1>You are down!</h1>_x000D_
  </div>_x000D_
</html

The "scroll-behavior" is telling the page how it should scroll and is so much easier than using javascript. Javascript will give you more options on speed and the smoothness but this will deliver without all of the confusing code.

There are already a few good answers to this question, but for the sake of completeness I wanted to point out that the applicable section of the C standard is 5.1.2.2.3/15 (which is the same as section 1.9/9 in the C++11 standard). This section states that operators can only be regrouped if they are really associative or commutative.

I have found that the best solution is to branch off your stash and do a resolution afterwards.

git stash branch <branch-name>

if you drop of clear your stash, you may lose your changes and you will have to recur to the reflog.

You can use MERGE Statement, This statement is used to insert data if not exist or update if does exist.

MERGE INTO Employee AS e
using EmployeeUpdate AS eu
ON e.EmployeeID = eu.EmployeeID`

You should check for '' (empty string) before pushing into your array. Your array has elements that are empty strings. Then your album_text.length === 0 will work just fine.

Use directive to restrict the user to enter only numbers in the following way:

.directive('onlyNumber', function () {
    var regExp = /^[0-9]*$/;
    return {
        require: '?ngModel',
        restrict: 'A',
        priority: 1,
        link: function (scope, elm, attrs, ctrl) {
            ctrl.$validators.onlyNumber= function (modalValue) {
                return ctrl.$isEmpty(modalValue) || regExp.test(modalValue);
            };
        }
    };
    })

In HTML:

<input id="txtRollNumber" type="text" name="rollNumber" placeholder="Enter roll number*" ng-model="rollNumber" class="form-control" maxlength="100" required only-number />

Angular2:

    import { Directive, ElementRef, HostListener, Input } from '@angular/core';

@Directive({
  selector: '[OnlyNumber]'
})
export class OnlyNumber {

  constructor(private el: ElementRef) { }

  @Input() OnlyNumber: boolean;

  @HostListener('keydown', ['$event']) onKeyDown(event) {
    let e = <KeyboardEvent> event;
    if (this.OnlyNumber) {
      if ([46, 8, 9, 27, 13, 110, 190].indexOf(e.keyCode) !== -1 ||
        // Allow: Ctrl+A
        (e.keyCode === 65 && (e.ctrlKey || e.metaKey)) ||
        // Allow: Ctrl+C
        (e.keyCode === 67 && (e.ctrlKey || e.metaKey)) ||
        // Allow: Ctrl+V
        (e.keyCode === 86 && (e.ctrlKey || e.metaKey)) ||
        // Allow: Ctrl+X
        (e.keyCode === 88 && (e.ctrlKey || e.metaKey)) ||
        // Allow: home, end, left, right
        (e.keyCode >= 35 && e.keyCode <= 39)) {
          // let it happen, don't do anything
          return;
        }
        // Ensure that it is a number and stop the keypress
        if ((e.shiftKey || (e.keyCode < 48 || e.keyCode > 57)) && (e.keyCode < 96 || e.keyCode > 105)) {
            e.preventDefault();
        }
      }
  }
}

And need to write the directive name in your input as an attribute.

<input OnlyNumber="true" />

There are many articles about writing code to import an excel file, but this is a manual/shortcut version:

If you don't need to import your Excel file programmatically using code you can do it very quickly using the menu in SQL Management Studio.

The quickest way to get your Excel file into SQL is by using the import wizard:

1. Open SSMS (Sql Server Management Studio) and connect to the database where you want to import your file into.
2. Import Data: in SSMS in Object Explorer under 'Databases' right-click the destination database, select Tasks, Import Data. An import wizard will pop up (you can usually just click 'Next' on the first screen).

3. The next window is 'Choose a Data Source', select Excel:

   • In the 'Data Source' dropdown list select Microsoft Excel (this option should appear automatically if you have excel installed).

   • Click the 'Browse' button to select the path to the Excel file you want to import.

   • Select the version of the excel file (97-2003 is usually fine for files with a .XLS extension, or use 2007 for newer files with a .XLSX extension)
   • Tick the 'First Row has headers' checkbox if your excel file contains headers.
   • Click next.

4. On the 'Choose a Destination' screen, select destination database:
   • Select the 'Server name', Authentication (typically your sql username & password) and select a Database as destination. Click Next.

5. On the 'Specify Table Copy or Query' window:

   • For simplicity just select 'Copy data from one or more tables or views', click Next.

6. 'Select Source Tables:' choose the worksheet(s) from your Excel file and specify a destination table for each worksheet. If you don't have a table yet the wizard will very kindly create a new table that matches all the columns from your spreadsheet. Click Next.

7. Click Finish.

To do with javascript you could do something like this:

<script type="Text/javascript">
var text = <?= $text_from_db; ?>
</script>

Then you can use whatever you want in your javascript to put the text var into the textbox.

You can use this plugin, but for printing purpose i have added some code like <button onclick="window.print();">Print</button> and for saving image <button onclick="savePhoto();">Save Picture</button>

     function savePhoto() {
     var canvas = document.getElementById("canvas");
     var img    = canvas.toDataURL("image/png");
     window.location = img;}

checkout this plugin http://www.williammalone.com/articles/create-html5-canvas-javascript-drawing-app

You can use the * operator before an iterable to expand it within the function call. For example:

timeseries_list = [timeseries1 timeseries2 ...]
r = scikits.timeseries.lib.reportlib.Report(*timeseries_list)

(notice the * before timeseries_list)

From the python documentation:

If the syntax *expression appears in the function call, expression must evaluate to an iterable. Elements from this iterable are treated as if they were additional positional arguments; if there are positional arguments x1, ..., xN, and expression evaluates to a sequence y1, ..., yM, this is equivalent to a call with M+N positional arguments x1, ..., xN, y1, ..., yM.

This is also covered in the python tutorial, in a section titled Unpacking argument lists, where it also shows how to do a similar thing with dictionaries for keyword arguments with the ** operator.

Can you guarantee that the BigDecimal will never contain a value larger than Integer.MAX_VALUE?

If yes, then here's your code calling intValue:

Integer.valueOf(bdValue.intValue())

This may not be the most effective solution. But this worked for me every time... I call this function where ever i need to listen to the softKeyboard.

boolean isOpened = false;

public void setListenerToRootView() {
    final View activityRootView = getWindow().getDecorView().findViewById(android.R.id.content);
    activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {

            int heightDiff = activityRootView.getRootView().getHeight() - activityRootView.getHeight();
            if (heightDiff > 100) { // 99% of the time the height diff will be due to a keyboard.
                Toast.makeText(getApplicationContext(), "Gotcha!!! softKeyboardup", 0).show();

                if (isOpened == false) {
                    //Do two things, make the view top visible and the editText smaller
                }
                isOpened = true;
            } else if (isOpened == true) {
                Toast.makeText(getApplicationContext(), "softkeyborad Down!!!", 0).show();
                isOpened = false;
            }
        }
    });
}

Note: This approach will cause issues if the user uses a floating keyboard.

Another flexible way using classpath containing fat jar (-cp fat.jar) or all jars (-cp "$JARS_DIR/*") and another custom config classpath or folder containing configuration files usually elsewhere and outside jar. So instead of the limited java -jar, use the more flexible classpath way as follows:

java \
   -cp fat_app.jar \ 
   -Dloader.path=<path_to_your_additional_jars or config folder> \
   org.springframework.boot.loader.PropertiesLauncher

See Spring-boot executable jar doc and this link

If you do have multiple MainApps which is common, you can use How do I tell Spring Boot which main class to use for the executable jar?

You can add additional locations by setting an environment variable LOADER_PATH or loader.path in loader.properties (comma-separated list of directories, archives, or directories within archives). Basically loader.path works for both java -jar or java -cp way.

And as always you can override and exactly specify the application.yml it should pickup for debugging purpose

--spring.config.location=/some-location/application.yml --debug

The easiest way is to use the modulus division operator.

if ($counter % 3 == 0) {
   echo 'image file';
}

How this works: Modulus division returns the remainder. The remainder is always equal to 0 when you are at an even multiple.

There is one catch: 0 % 3 is equal to 0. This could result in unexpected results if your counter starts at 0.

In Java 8

To create a non-empty list of fixed size (operations like add, remove, etc., are not supported):

List<Integer> list = Arrays.asList(1, 2); // but, list.set(...) is supported

To create a non-empty mutable list:

List<Integer> list = new ArrayList<>(Arrays.asList(3, 4));

In Java 9

Using a new List.of(...) static factory methods:

List<Integer> immutableList = List.of(1, 2);

List<Integer> mutableList = new ArrayList<>(List.of(3, 4));

In Java 10

Using the Local Variable Type Inference:

var list1 = List.of(1, 2);

var list2 = new ArrayList<>(List.of(3, 4));

var list3 = new ArrayList<String>();

And follow best practices...

Don't use raw types

Since Java 5, generics have been a part of the language - you should use them:

List<String> list = new ArrayList<>(); // Good, List of String

List list = new ArrayList(); // Bad, don't do that!

Program to interfaces

For example, program to the List interface:

List<Double> list = new ArrayList<>();

Instead of:

ArrayList<Double> list = new ArrayList<>(); // This is a bad idea!

You can use the Closure compiler to compile your javascript.

You can also use CoffeeScript to compile your coffeescript to javascript.

What do you want to achieve with compiling?

The task of compiling arbitrary non-blocking JavaScript down to say, C sounds very daunting.

There really isn't that much speed to be gained by compiling to C or ASM. If you want speed gain offload computation to a C program through a sub process.

Try the Choice command. It's been around since MSDOS 6.0, and should do the trick.

Use the /T parameter to specify the timeout in seconds and the /D parameter to specify the default selection and ignore then selected choice.

The one thing that might be an issue is if the user types one of the choice characters before the timeout period elapses. A partial work-around is to obfuscate the situation -- use the /N argument to hide the list of valid choices and only have 1 character in the set of choices so it will be less likely that the user will type a valid choice before the timeout expires.

Below is the help text on Windows Vista. I think it is the same on XP, but look at the help text on an XP computer to verify.

C:\>CHOICE /?

CHOICE [/C choices] [/N] [/CS] [/T timeout /D choice] [/M text]

Description:
    This tool allows users to select one item from a list
    of choices and returns the index of the selected choice.

Parameter List:
   /C    choices       Specifies the list of choices to be created.
                       Default list is "YN".

   /N                  Hides the list of choices in the prompt.
                       The message before the prompt is displayed
                       and the choices are still enabled.

   /CS                 Enables case-sensitive choices to be selected.
                       By default, the utility is case-insensitive.

   /T    timeout       The number of seconds to pause before a default
                       choice is made. Acceptable values are from 0 to
                       9999. If 0 is specified, there will be no pause
                       and the default choice is selected.

   /D    choice        Specifies the default choice after nnnn seconds.
                       Character must be in the set of choices specified
                       by /C option and must also specify nnnn with /T.

   /M    text          Specifies the message to be displayed before
                       the prompt. If not specified, the utility
                       displays only a prompt.

   /?                  Displays this help message.

   NOTE:
   The ERRORLEVEL environment variable is set to the index of the
   key that was selected from the set of choices. The first choice
   listed returns a value of 1, the second a value of 2, and so on.
   If the user presses a key that is not a valid choice, the tool
   sounds a warning beep. If tool detects an error condition,
   it returns an ERRORLEVEL value of 255. If the user presses
   CTRL+BREAK or CTRL+C, the tool returns an ERRORLEVEL value
   of 0. When you use ERRORLEVEL parameters in a batch program, list
   them in decreasing order.

Examples:
   CHOICE /?
   CHOICE /C YNC /M "Press Y for Yes, N for No or C for Cancel."
   CHOICE /T 10 /C ync /CS /D y
   CHOICE /C ab /M "Select a for option 1 and b for option 2."
   CHOICE /C ab /N /M "Select a for option 1 and b for option 2."

You can't use findViewById() on menu items in onCreate() because the menu layout isn't inflated yet. You could create a global Menu variable and initialize it in the onCreateOptionsMenu() and then use it in your onClick().

private Menu menu;

In your onCreateOptionsMenu()

this.menu = menu;

In your button's onClick() method

menu.getItem(0).setIcon(ContextCompat.getDrawable(this, R.drawable.ic_launcher));

A tool like systemtap (or a tracer) can monitor kernel signal-transmission logic and report. e.g., https://sourceware.org/systemtap/examples/process/sigmon.stp

# stap .../sigmon.stp -x 31994 SIGKILL
   SPID     SNAME            RPID  RNAME            SIGNUM SIGNAME
   5609     bash             31994 find             9      SIGKILL

The filtering if block in that script can be adjusted to taste, or eliminated to trace systemwide signal traffic. Causes can be further isolated by collecting backtraces (add a print_backtrace() and/or print_ubacktrace() to the probe, for kernel- and userspace- respectively).

You can do something like req.param('tagId')

My site configuration file is example.conf in sites-available folder So you can create a symbolic link as

ln -s /etc/nginx/sites-available/example.conf /etc/nginx/sites-enabled/

btn-group-justified and btn-group only work for static content but not on dynamically created buttons, and fixed with of button in css is not practical as it stay on the same width even all content are short.

My solution: put the same class to group of buttons then loop to all of them, get the width of the longest button and apply it to all

var bwidth=0
$("button.btnGroup").each(function(i,v){
    if($(v).width()>bwidth) bwidth=$(v).width();
});
$("button.btnGroup").width(bwidth);

What worked for me on android 4.4 was to do the following: Settings -> Wireless & Networks -> Mobile networks -> Make sure both Data enabled and Data roaming is enabled.

Use this.getClass().getCanonicalName() to get the full class name.

Note that a package / class name ("a.b.C") is different from the path of the .class files (a/b/C.class), and that using the package name / class name to derive a path is typically bad practice. Sets of class files / packages can be in multiple different class paths, which can be directories or jar files.

You can't edit the image via CSS. The only solution I can think of is to edit the image and change its opacity, or make different images with all the opacities needed.

You can use assertThrows(). My example is taken from the docs http://junit.org/junit5/docs/current/user-guide/

import org.junit.jupiter.api.Test;

import static org.junit.jupiter.api.Assertions.assertEquals;
import static org.junit.jupiter.api.Assertions.assertThrows;

....

@Test
void exceptionTesting() {
    Throwable exception = assertThrows(IllegalArgumentException.class, () -> {
        throw new IllegalArgumentException("a message");
    });
    assertEquals("a message", exception.getMessage());
}

As said by others, RowDataBound or RowCreated event should work but if you want to avoid events declaration and put the whole code just below DataBind function call, you can do the following:

GridView1.DataBind()
If GridView1.Rows.Count > 0 Then
    GridView1.HeaderRow.Cells(0).Visible = False
    For i As Integer = 0 To GridView1.Rows.Count - 1
        GridView1.Rows(i).Cells(0).Visible = False
    Next
End If

 textBlock.Foreground = new SolidColorBrush(Colors.White);

Using the Bootstrap pull-right helper didn't work for us because it uses float: right, which forces inline-block elements to become block. And when the .btns become block, they lose the natural margin that inline-block was providing them as quasi-textual elements.

So instead we used direction: rtl; on the parent element, which causes the text inside that element to layout from right to left, and that causes inline-block elements to layout from right to left, too. You can use LESS like the following to prevent children from being laid out rtl too:

/* Flow the inline-block .btn starting from the right. */
.btn-container-right {
  direction: rtl;

  * {
    direction: ltr;
  }
}

and use it like:

<div class="btn-container-right">
    <button class="btn">Click Me</button>
</div>

Just to add a different approach - you can simply cast your ref, something like:

let myInputElement: Element = this.refs["myInput"] as Element

&tl;dr: No, you can't disable a textbox using CSS.

pointer-events: none works but on IE the CSS property only works with IE 11 or higher, so it doesn't work everywhere on every browser. Except for that you cannot disable a textbox using CSS.

However you could disable a textbox in HTML like this:

<input value="...." readonly />

But if the textbox is in a form and you want the value of the textbox to be not submitted, instead do this:

<input value="...." disabled />

So the difference between these two options for disabling a textbox is that disabled cannot allow you to submit the value of the input textbox but readonly does allow.

For more information on the difference between these two, see "What is the difference between disabled="disabled" and readonly="readonly".

Based on the answer for this question, I created a static class and added these. Thought it might be useful for some people.

public static class RegexConvert
{
    public static string ToAlphaNumericOnly(this string input)
    {
        Regex rgx = new Regex("[^a-zA-Z0-9]");
        return rgx.Replace(input, "");
    }

    public static string ToAlphaOnly(this string input)
    {
        Regex rgx = new Regex("[^a-zA-Z]");
        return rgx.Replace(input, "");
    }

    public static string ToNumericOnly(this string input)
    {
        Regex rgx = new Regex("[^0-9]");
        return rgx.Replace(input, "");
    }
}

Then the methods can be used as:

string example = "asdf1234!@#$";
string alphanumeric = example.ToAlphaNumericOnly();
string alpha = example.ToAlphaOnly();
string numeric = example.ToNumericOnly();

Now, you can

#wrapper { display: flow-root; }

• Compatibility https://caniuse.com/flow-root

the code that worked for me

ALTER TABLE `table name`
ADD COLUMN `id` INT NOT NULL AUTO_INCREMENT,
ADD PRIMARY KEY (`id`);

Why does the error mention tuples?

Others have explained that the problem was the missing ,, but the final mystery is why does the error message talk about tuples?

The reason is that your:

["pennies", '2.5', '50.0', '.01'] 
["nickles", '5.0', '40.0', '.05']

can be reduced to:

[][1, 2]

as mentioned by 6502 with the same error.

But then __getitem__, which deals with [] resolution, converts object[1, 2] to a tuple:

class C(object):
    def __getitem__(self, k):
        return k

# Single argument is passed directly.
assert C()[0] == 0

# Multiple indices generate a tuple.
assert C()[0, 1] == (0, 1)

and the implementation of __getitem__ for the list built-in class cannot deal with tuple arguments like that.

More examples of __getitem__ action at: https://stackoverflow.com/a/33086813/895245

try

pip3 install --upgrade pandas

An easy way to write it is with if_na from hablar:

library(dplyr)
library(hablar)

df <- tibble(a = c(1, 2, 3, NA, 5, 6, 8))

df %>% 
  mutate(a = if_na(a, 0))

which returns:

      a
  <dbl>
1     1
2     2
3     3
4     0
5     5
6     6
7     8

You can add flex-direction:column to flex-container

.flex-container {
  flex-direction: column;
}

Add display:inline-block to flex-item

.flex-item {
 display: inline-block;
}

because you added width and height has no effect on this element since it has a display of inline. Try adding display:inline-block or display:block. Learn more about width and height.

Also add to row class( you are given row{} not taken as style)

.row{
  width:100%;
  margin:0 auto;
  text-align:center;
}

Working Demo in Row :

.flex-container {
  padding: 0;
  margin: 0;
  list-style: none;
  display: flex;
  align-items: center;
  justify-content:center;
  flex-direction:column;
}
.row{
  width:100%;
  margin:0 auto;
  text-align:center;
}
.flex-item {
  background: tomato;
  padding: 5px;
  width: 200px;
  height: 150px;
  margin: 10px;
  line-height: 150px;

Using Moment.

I can't recommend the use of Moment enough. If you are able to use third-party libraries, I highly recommend doing so. Beyond just formatting, it deals with timezones, parsing, durations and time travel extremely well and will pay dividends in simplicity and time (at the small expense of size, abstraction and performance).

Usage

You wanted something that looked like this:

Friday 2:00pm 1 Feb 2013

Well, with Moment all you need you to do is this:

import Moment from "moment";

Moment().format( "dddd h:mma D MMM YYYY" ); //=> "Wednesday 9:20am 9 Dec 2020"

And if you wanted to match that exact date and time, all you would need to do is this:

import Moment from "moment";

Moment( "2013-2-1 14:00:00" ).format( "dddd h:mma D MMM YYYY" ) ); //=> "Friday 2:00pm 1 Feb 2013"

There's a myriad of other formatting options that can be found here.

Install

Go to their home page to see more detailed instructions, but if you're using npm or yarn it's as simple as:

npm install moment --save

or

yarn add moment

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

I saw the below code working. Simple, but I guess not documented. Anyone else used the 'Execute' command ?

   Dim body, my_script_file
   Set Fso = CreateObject("Scripting.FileSystemObject")


   Set my_script_file = fso.OpenTextFile(FILE)
   body = my_script_file.ReadAll
    my_script_file.Close

    Execute body

Sorry my fault, try this...

#!/bin/bash
:

declare -r HEX_DIGITS="0123456789ABCDEF"

dec_value=$1
hex_value=""

until [ $dec_value == 0 ]; do

    rem_value=$((dec_value % 16))
    dec_value=$((dec_value / 16))

    hex_digit=${HEX_DIGITS:$rem_value:1}

    hex_value="${hex_digit}${hex_value}"

done

echo -e "${hex_value}"

Example:

$ ./dtoh 1024
400
