This link will help you in understanding pass by reference in C#. Basically,when an object of reference type is passed by value to an method, only methods which are available on that object can modify the contents of object.

For example List.sort() method changes List contents but if you assign some other object to same variable, that assignment is local to that method. That is why myList remains unchanged.

If we pass object of reference type by using ref keyword then we can assign some other object to same variable and that changes entire object itself.

(Edit: this is the updated version of the documentation linked above.)

Ask this questions yourself? And you will decide your DB selection.

1. Do you need master-master? Then CouchDB. Mainly CouchDB supports master-master replication which anticipates nodes being disconnected for long periods of time. MongoDB would not do well in that environment.
2. Do you need MAXIMUM R/W throughput? Then MongoDB
3. Do you need ultimate single-server durability because you are only going to have a single DB server? Then CouchDB.
4. Are you storing a MASSIVE data set that needs sharding while maintaining insane throughput? Then MongoDB.
5. Do you need strong consistency of data? Then MongoDB.
6. Do you need high availability of database? Then CouchDB.
7. Are you hoping multi databases and multi tables/ collections? Then MongoDB
8. You have a mobile app offline users and want to sync their activity data to a server? Then you need CouchDB.
9. Do you need large variety of querying engine? Then MongoDB
10. Do you need large community to be using DB? Then MongoDB

All compilers I know will replace a simple std::copy with a memcpy when it is appropriate, or even better, vectorize the copy so that it would be even faster than a memcpy.

In any case: profile and find out yourself. Different compilers will do different things, and it's quite possible it won't do exactly what you ask.

See this presentation on compiler optimisations (pdf).

Here's what GCC does for a simple std::copy of a POD type.

#include <algorithm>

struct foo
{
  int x, y;    
};

void bar(foo* a, foo* b, size_t n)
{
  std::copy(a, a + n, b);
}

Here's the disassembly (with only -O optimisation), showing the call to memmove:

bar(foo*, foo*, unsigned long):
    salq    $3, %rdx
    sarq    $3, %rdx
    testq   %rdx, %rdx
    je  .L5
    subq    $8, %rsp
    movq    %rsi, %rax
    salq    $3, %rdx
    movq    %rdi, %rsi
    movq    %rax, %rdi
    call    memmove
    addq    $8, %rsp
.L5:
    rep
    ret

If you change the function signature to

void bar(foo* __restrict a, foo* __restrict b, size_t n)

then the memmove becomes a memcpy for a slight performance improvement. Note that memcpy itself will be heavily vectorised.

Short Answer

super(DerivedClass, self).__init__()

Long Answer

What does super() do?

It takes specified class name, finds its base classes (Python allows multiple inheritance) and looks for the method (__init__ in this case) in each of them from left to right. As soon as it finds method available, it will call it and end the search.

How do I call init of all base classes?

Above works if you have only one base class. But Python does allow multiple inheritance and you might want to make sure all base classes are initialized properly. To do that, you should have each base class call init:

class Base1:
  def __init__():
    super(Base1, self).__init__()

class Base2:
  def __init__():
    super(Base2, self).__init__()

class Derived(Base1, Base2):
  def __init__():
    super(Derived, self).__init__()

What if I forget to call init for super?

The constructor (__new__) gets invoked in a chain (like in C++ and Java). Once the instance is created, only that instance's initialiser (__init__) is called, without any implicit chain to its superclass.

This one works!

floor(loge(n) / loge(2)) + 1

To include negative numbers, you can add an extra bit to specify the sign.

floor(loge(abs(n)) / loge(2)) + 2

if (in_array($id,$user_access_arr)==0)
{
    $this->Session->setFlash(__('Access Denied! You are not eligible to access this.'), 'flash_custom_success');
    return $this->redirect(array('controller'=>'Dashboard','action'=>'index'));
}

Otherwise we may change the default property configurator name, setting the property spring.config.name=test and then having class-path resource src/test/test.properties our native instance of org.springframework.boot.SpringApplication will be auto-configured from this separated test.properties, ignoring application properties;

Benefit: auto-configuration of tests;

Drawback: exposing "spring.config.name" property at C.I. layer

ref: http://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html

spring.config.name=application # Config file name

To expand on the existing great answers, a very simple way to get a great looking terminal is to use the open source Dotfiles project.

https://github.com/mathiasbynens/dotfiles

Installation is dead simple on OSX and Linux. Run the following command in Terminal.

git clone https://github.com/mathiasbynens/dotfiles.git && cd dotfiles && source bootstrap.sh

This is going to:

1. Git clone the repo.
2. cd into the folder.
3. Run the installation bash script.

This solution modifies Cycne's to use ES6 syntax and exit the loop early for external stylesheets. This solution does not modify external stylesheets

function changeStyle(findSelector, newDeclarations) {_x000D_
    // Change original css style declaration._x000D_
    document.styleSheets.forEach((sheet) => {_x000D_
      if (sheet.href) return;_x000D_
      const cssRulesList = sheet.cssRules;_x000D_
      cssRulesList.forEach((styleRule) => {_x000D_
        if (styleRule.selectorText === findSelector) {_x000D_
          Object.keys(newDeclarations).forEach((cssProp) => {_x000D_
            styleRule.style[cssProp] = newDeclarations[cssProp];_x000D_
          });_x000D_
        }_x000D_
      });_x000D_
    });_x000D_
  }_x000D_
_x000D_
  const styleDeclarations = {_x000D_
    'width': '200px',_x000D_
    'height': '400px',_x000D_
    'color': '#F00'_x000D_
  };_x000D_
  changeStyle('.paintBox', styleDeclarations);

You must also have at least one style tag in your HTML head section, for example

<style> .paintBox {background-color: white;}</style>

Here is one way to do it. It uses the ability of R to construct file paths based on the platform and hence will work on both Mac OS and Windows. Moreover, you don't need to convert your xls file to csv, as there are many R packages that will help you read xls directly (e.g. gdata package).

# get user's home directory
home = setwd(Sys.getenv("HOME"));

# construct path to file
fpath = file.path(home, "Desktop", "RTrial.xls");

# load gdata library to read xls files
library(gdata);

# read xls file
Rtrial = read.xls(fpath);

Let me know if this works.

The Subject, in security, is the thing being secured. In this case it could be a persons email or a website or a machine.

If we take the example of an email, say my email, then the subject key container would be the protected location containing my private key.

The certificate store usually refers to Microsoft certificate store which contains certificates form trusted roots, machines on the network, people etc. In my case the subjects certificate store would be the place, within this store, holding my certificates.

If you are working within a microsoft domain then the subject name will invariably hold the Distinguished Name, of the subject, which is how the domain references the subject and holds it in its directory. e.g. CN=Mark Sutton, OU=Developers, O=Mycompany C=UK

To look at your certificates on a microsoft machine:-

Log in as you run>mmc Select File>add/remove snap-in and select certificates then select my user account click Finish then close then ok. Look in the personal area of the store.

In the other areas of the store you will see the other trusted certificates used to validate signatures etc.

Originally javax was intended to be for extensions, and sometimes things would be promoted out of javax into java.

One issue was Netscape (and probably IE) limiting classes that could be in the java package.

When Swing was set to "graduate" to java from javax there was sort of a mini-blow up because people realized that they would have to modify all of their imports. Given that backwards compatibility is one of the primary goals of Java they changed their mind.

At that point in time, at least for the community (maybe not for Sun) the whole point of javax was lost. So now we have some things in javax that probably should be in java... but aside from the people that chose the package names I don't know if anyone can figure out what the rationale is on a case-by-case basis.

By experiment I was able to observe this:

When SQL Profiler 2005 or SQL Profiler 2000 is used with database residing in SQLServer 2000 - problem mentioned problem persists, but when SQL Profiler 2005 is used with SQLServer 2005 database, it works perfect!

In Summary, the issue seems to be prevalent in SQLServer 2000 & rectified in SQLServer 2005.

The solution for the issue when dealing with SQLServer 2000 is (as explained by wearejimbo)

1. Identify the DatabaseID of the database you want to filter by querying the sysdatabases table as below

   SELECT * 
   FROM master..sysdatabases 
   WHERE name like '%your_db_name%'   -- Remove this line to see all databases
   ORDER BY dbid
   

2. Use the DatabaseID Filter (instead of DatabaseName) in the New Trace window of SQL Profiler 2000

You can use Comparator.reverseOrder() to have a comparator giving the reverse of the natural ordering.

If you want to reverse the ordering of an existing comparator, you can use Comparator.reversed().

Sample code:

Stream.of(1, 4, 2, 5)
    .sorted(Comparator.reverseOrder()); 
    // stream is now [5, 4, 2, 1]

Stream.of("foo", "test", "a")
    .sorted(Comparator.comparingInt(String::length).reversed()); 
    // stream is now [test, foo, a], sorted by descending length

You need to register a domain(on GoDaddy for example) and put a load balancer in front of your ec2 instance - as DigaoParceiro said in his answer.

The issue is that domains generated by amazon on your ec2 instances are ephemeral. Today the domain is belonging to you, tomorrow it may not.

For that reason, let's encrypt throws an error when you try to register a certificate on amazon generated domain that states:

The ACME server refuses to issue a certificate for this domain name, because it is forbidden by policy

More details about this here: https://community.letsencrypt.org/t/policy-forbids-issuing-for-name-on-amazon-ec2-domain/12692/4

defaultConfig {
ndk {
            abiFilters "armeabi-v7a", "x86", "armeabi", "mips"
    }
}

Just add these line in build.gradle app level

A great substitute for np.isnan() and pd.isnull() is

for i in range(0,a.shape[0]):
    if(a[i]!=a[i]):
       //do something here
       //a[i] is nan

since only nan is not equal to itself.

You could also try to run the following command:

devenv /ResetSkipPkgs

This worked for me: Open task manager (of your OS) and kill adb.exe process. Now start adb again, now adb should start normally.

I had troubles because I used apt to install python-virtualenv package. To get it working I had to remove this package with apt-get remove python-virtualenv and install it with pip install virtualenv.

You want the CASE statement:

SELECT
  CASE 
    WHEN @SelectField1 = 1 THEN Field1
    WHEN @SelectField2 = 1 THEN Field2
    ELSE NULL
  END AS NewField
FROM Table

EDIT: My example is for combining the two fields into one field, depending on the parameters supplied. It is a one-or-neither solution (not both). If you want the possibility of having both fields in the output, use Quassnoi's solution.

This will drop the outermost level from the hierarchical column index:

df = data.groupby(...).agg(...)
df.columns = df.columns.droplevel(0)

If you'd like to keep the outermost level, you can use the ravel() function on the multi-level column to form new labels:

df.columns = ["_".join(x) for x in df.columns.ravel()]

For example:

import pandas as pd
import pandas.rpy.common as com
import numpy as np

data = com.load_data('Loblolly')
print(data.head())
#     height  age Seed
# 1     4.51    3  301
# 15   10.89    5  301
# 29   28.72   10  301
# 43   41.74   15  301
# 57   52.70   20  301

df = data.groupby('Seed').agg(
    {'age':['sum'],
     'height':['mean', 'std']})
print(df.head())
#       age     height           
#       sum        std       mean
# Seed                           
# 301    78  22.638417  33.246667
# 303    78  23.499706  34.106667
# 305    78  23.927090  35.115000
# 307    78  22.222266  31.328333
# 309    78  23.132574  33.781667

df.columns = df.columns.droplevel(0)
print(df.head())

yields

      sum        std       mean
Seed                           
301    78  22.638417  33.246667
303    78  23.499706  34.106667
305    78  23.927090  35.115000
307    78  22.222266  31.328333
309    78  23.132574  33.781667

Alternatively, to keep the first level of the index:

df = data.groupby('Seed').agg(
    {'age':['sum'],
     'height':['mean', 'std']})
df.columns = ["_".join(x) for x in df.columns.ravel()]

yields

      age_sum   height_std  height_mean
Seed                           
301        78    22.638417    33.246667
303        78    23.499706    34.106667
305        78    23.927090    35.115000
307        78    22.222266    31.328333
309        78    23.132574    33.781667

You can create or edit your .gitignore file for your repo by going to the Settings view in Team Explorer, then selecting Repository Settings. Select Edit for your .gitignore.

It automatically creates filters that will ignore all the VS specific build directories etc.

Consistency is what everyone strongly suggest, the rest is upto you as long as it works.

For beginners its easy to get carried away and we name whatever we want at that time. This make sense at that point but a headache later.

foo foobar or foo_bar is great. We name our table straight forward as much as possible and only use underscore if they are two different words. studentregistration to student_registration

like @Zbyszek says, having a simple id is more than enough for the auto-increment. The simplier the better. Why do you need foo_id? We had the same problem early on, we named all our columns with the table prefix. like foo_id, foo_name, foo_age. We dropped the tablename now and kept only the col as short as possible.

Since we are using just an id for PK we will be using foo_bar_fk (tablename is unique, folowed by the unique PK, followed by the _fk) as foreign key. We don't add id to the col name because it is said that the name 'id' is always the PK of the given table. So we have just the tablename and the _fk at the end.

For constrains we remove all underscores and join with camelCase (tablename + Colname + Fk) foobarUsernameFk (for username_fk col). It's just a way we are following. We keep a documentation for every names structures.

When keeping the col name short, we should also keep an eye on the RESTRICTED names.

+------------------------------------+
|               foobar               |
+------------------------------------+
| id (PK for the current table)      |
| username_fk (PK of username table) |
| location (other column)            |
| tel (other column)                 |
+------------------------------------+

It can be very useful when flattening a hierarchy and/or mapping objects. Instead of:

if (Model.Model2 == null
  || Model.Model2.Model3 == null
  || Model.Model2.Model3.Model4 == null
  || Model.Model2.Model3.Model4.Name == null)
{
  mapped.Name = "N/A"
}
else
{
  mapped.Name = Model.Model2.Model3.Model4.Name;
}

It can be written like (same logic as above)

mapped.Name = Model.Model2?.Model3?.Model4?.Name ?? "N/A";

DotNetFiddle.Net Working Example.

(the ?? or null-coalescing operator is different than the ? or null conditional operator).

It can also be used out side of assignment operators with Action. Instead of

Action<TValue> myAction = null;

if (myAction != null)
{
  myAction(TValue);
}

It can be simplified to:

myAction?.Invoke(TValue);

DotNetFiddle Example:

using System;

public class Program
{
  public static void Main()
  {
    Action<string> consoleWrite = null;

    consoleWrite?.Invoke("Test 1");

    consoleWrite = (s) => Console.WriteLine(s);

    consoleWrite?.Invoke("Test 2");
  }
}

Result:

Test 2

'a' in x

and a quick search reveals some nice information about it: http://docs.python.org/3/tutorial/datastructures.html#dictionaries

I would like to add to some of the other answers here, if you don't need the first item but say the second number for example you can use rownumber in a subquery and base your result set off of that.

SELECT * FROM
(
    SELECT
        ROW_NUM() OVER (PARTITION BY Id ORDER BY record_date, other_cols) as rownum,
        *
    FROM products P
) INNER
WHERE rownum = 2

This also allows you to order off multiple columns in the subquery which may help if two record_dates have identical values. You can also partition off of multiple columns if needed by delimiting them with a comma

$ hadoop fs -rmdir {directory_name}

The default shortcut key is Ctrl-Alt-C.

The problem with push command is that you your local and remote repository doesn't match. IF you initialize readme by default when creating new repository from git hub, then, master branch is automatically created. However, when you try to push that has no any branch. you cannot push... So, the best practice is to create repo without default readme initialization.

If you want to keep your CustomView and its xib independent of File's Owner, then follow these steps

• Leave the File's Owner field empty.
• Click on actual view in xib file of your CustomView and set its Custom Class as CustomView (name of your custom view class)
• Add IBOutlet in .h file of your custom view.
• In .xib file of your custom view, click on view and go in Connection Inspector. Here you will all your IBOutlets which you define in .h file
• Connect them with their respective view.

in .m file of your CustomView class, override the init method as follow

-(CustomView *) init{
    CustomView *result = nil;
    NSArray* elements = [[NSBundle mainBundle] loadNibNamed: NSStringFromClass([self class]) owner:self options: nil];
    for (id anObject in elements)
    {
        if ([anObject isKindOfClass:[self class]])
        {
            result = anObject;
            break;
        }
    }
    return result;
}

Now when you want to load your CustomView, use the following line of code [[CustomView alloc] init];

You should be able to achieve that with the help of EditText's method setSelection(), see here

try to implement with javascript this:

<div id="mydiv" onclick="myhref('http://web.com');" >some stuff </div>
<script type="text/javascript">
    function myhref(web){
      window.location.href = web;}
</script>

If you want greater control you can use javascript rather than use the meta tag. This would allow you to have a visual of some kind, e.g. a countdown.

Here is a very basic approach using setTimeout()

<html>_x000D_
    <body>_x000D_
    <p>You will be redirected in 3 seconds</p>_x000D_
    <script>_x000D_
        var timer = setTimeout(function() {_x000D_
            window.location='http://example.com'_x000D_
        }, 3000);_x000D_
    </script>_x000D_
</body>_x000D_
</html>

try with screen -d -r or screen -D -RR

There is no need for an UDF here. Column already provides cast method with DataType instance :

from pyspark.sql.types import DoubleType

changedTypedf = joindf.withColumn("label", joindf["show"].cast(DoubleType()))

or short string:

changedTypedf = joindf.withColumn("label", joindf["show"].cast("double"))

where canonical string names (other variations can be supported as well) correspond to simpleString value. So for atomic types:

from pyspark.sql import types 

for t in ['BinaryType', 'BooleanType', 'ByteType', 'DateType', 
          'DecimalType', 'DoubleType', 'FloatType', 'IntegerType', 
           'LongType', 'ShortType', 'StringType', 'TimestampType']:
    print(f"{t}: {getattr(types, t)().simpleString()}")

BinaryType: binary
BooleanType: boolean
ByteType: tinyint
DateType: date
DecimalType: decimal(10,0)
DoubleType: double
FloatType: float
IntegerType: int
LongType: bigint
ShortType: smallint
StringType: string
TimestampType: timestamp

and for example complex types

types.ArrayType(types.IntegerType()).simpleString()   

'array<int>'

types.MapType(types.StringType(), types.IntegerType()).simpleString()

'map<string,int>'

There is indeed a big difference, which you should keep in mind. setScale really set the scale of your number whereas round does round your number to the specified digits BUT it "starts from the leftmost digit of exact result" as mentioned within the jdk. So regarding your sample the results are the same, but try 0.0034 instead. Here's my note about that on my blog:

http://araklefeistel.blogspot.com/2011/06/javamathbigdecimal-difference-between.html

If set is sufficient, ConcurrentSkipListSet might be used. (Its implementation is based on ConcurrentSkipListMap which implements a skip list.)

In MongoDB, the db.collection.remove() method removes documents from a collection. You can remove all documents from a collection, remove all documents that match a condition, or limit the operation to remove just a single document.

If you are using mongo sheel, just do:

db.Datetime.remove({})

In your case, you need:

You didn't show me the delete button, so this button is just an example:

<a class="button__delete"></a>

Change the controller to:

exports.destroy = function(req, res, next) {
    Datetime.remove({}, function(err) {
            if (err) {
                console.log(err)
            } else {
                res.end('success');
            }
        }
    );
};

Insert this ajax delete method in your client js file:

        $(document).ready(function(){
            $('.button__delete').click(function() {
                var dataId = $(this).attr('data-id');

                if (confirm("are u sure?")) {
                    $.ajax({
                        type: 'DELETE',
                        url: '/',
                        success: function(response) {
                            if (response == 'error') {
                                console.log('Err!');
                            }
                            else {
                                alert('Success');
                                location.reload();
                            }
                        }
                    });
                } else {
                    alert('Canceled!');
                }
            });
        });

layout_weight tells Android how to distribute your Views in a LinearLayout. Android then first calculates the total proportion required for all Views that have a weight specified and places each View according to what fraction of the screen it has specified it needs. In the following example, Android sees that the TextViews have a layout_weight of 0 (this is the default) and the EditTexts have a layout_weight of 2 each, while the Button has a weight of 1. So Android allocates 'just enough' space to display tvUsername and tvPassword and then divides the remainder of the screen width into 5 equal parts, two of which are allocated to etUsername, two to etPassword and the last part to bLogin:

<LinearLayout android:orientation="horizontal" ...>

    <TextView android:id="@+id/tvUsername" 
    android:text="Username" 
    android:layout_width="wrap_content" ... />

    <EditText android:id="@+id/etUsername"
    android:layout_width="0dp"
    android:layout_weight="2" ... />

    <TextView android:id="@+id/tvPassword"
    android:text="Password"
    android:layout_width="wrap_content" />

    <EditText android:id="@+id/etPassword"
    android:layout_width="0dp"
    android:layout_weight="2" ... />

    <Button android:id="@+id/bLogin"
    android:layout_width="0dp"
    android:layout_weight="1"
    android:text="Login"... />

</LinearLayout>

It looks like:
and

if you want to change all the keys:

d = {'x':1, 'y':2, 'z':3}
d1 = {'x':'a', 'y':'b', 'z':'c'}

In [10]: dict((d1[key], value) for (key, value) in d.items())
Out[10]: {'a': 1, 'b': 2, 'c': 3}

if you want to change single key: You can go with any of the above suggestion.

It's easy, just use list.Find(x => x.name == "stringNameOfObjectToFind");

After searching a lot I found a solution:

Go to Build-> Build Apk(s).

After creating apk you will see a dialog as below.

Click on locate and install it in your phone

Enjoy

You can use:

cat f.csv | sed 's/,/ /g' |  awk '{print $1 " / " $4}'

or

echo "Hello,World,Questions,Answers,bash shell,script" | sed 's/,/ /g' |  awk '{print $1 " / " $4}'

This is the part that replace comma with space

sed 's/,/ /g'

you need to add jar file in your build path..

commons-dbcp-1.1-RC2.jar

or any version of that..!!!!

ADDED : also make sure you have commons-pool-1.1.jar too in your build path.

ADDED: sorry saw complete list of jar late... may be version clashes might be there.. better check out..!!! just an assumption.

If you use Docker, you should read this file: https://github.com/cloudbees/jenkins-ci.org-docker/blob/master/plugins.sh

Example of a parent Dockerfile:

FROM jenkins
COPY plugins.txt /plugins.txt
RUN /usr/local/bin/plugins.sh /plugins.txt

plugins.txt

<name>:<version>
<name2>:<version2>

You need to use [[, the programmatic equivalent of $. Otherwise, for example, when i is col1, R will look for df$i instead of df$col1.

for(i in names(df)){
  df[[paste(i, 'length', sep="_")]] <- str_length(df[[i]])
}

You can if your processor is 64-bit and Virtualization Technology (VT) extension is enabled (it can be switched off in BIOS). You can't do it on 32-bit processor.

To check this under Linux you just need to look into /proc/cpuinfo file. Just look for the appropriate flag (vmx for Intel processor or svm for AMD processor)

egrep '(vmx|svm)' /proc/cpuinfo

To check this under Windows you need to use a program like CPU-Z which will display your processor architecture and supported extensions.

You need to set an own WebViewClient for your WebView by extending the WebViewClient class.

You need to implement the two methods onPageStarted (show here) and onPageFinished (dismiss here).

For something that works with the 2.X standard library try:

calendar.timegm(time.strptime(date.split(".")[0]+"UTC", "%Y-%m-%dT%H:%M:%S%Z"))

calendar.timegm is the missing gm version of time.mktime.

Call me lazy but coding a Converter seems like a lot of unnecessary work. I'm using Primefaces and, not having used a plain vanilla JSF2 listbox or dropdown menu before, I just assumed (being lazy) that the widget could handle complex objects, i.e. pass the selected object as is to its corresponding getter/setter like so many other widgets do. I was disappointed to find (after hours of head scratching) that this capability does not exist for this widget type without a Converter. In fact if you supply a setter for the complex object rather than for a String, it fails silently (simply doesn't call the setter, no Exception, no JS error), and I spent a ton of time going through BalusC's excellent troubleshooting tool to find the cause, to no avail since none of those suggestions applied. My conclusion: listbox/menu widget needs adapting that other JSF2 widgets do not. This seems misleading and prone to leading the uninformed developer like myself down a rabbit hole.

In the end I resisted coding a Converter and found through trial and error that if you set the widget value to a complex object, e.g.:

<p:selectOneListbox id="adminEvents" value="#{testBean.selectedEvent}">

... when the user selects an item, the widget can call a String setter for that object, e.g. setSelectedThing(String thingString) {...}, and the String passed is a JSON String representing the Thing object. I can parse it to determine which object was selected. This feels a little like a hack, but less of a hack than a Converter.

As Tr?n Si Long suggested, use

String[] mStrings = new String[title.length];

And replace string concatation with proper parenthesis.

mStrings[i] = (urlbase + (title[i].replaceAll("[^a-zA-Z]", ""))).toLowerCase() + imgSel;

Try this. If it's problem due to concatation, it will be resolved with proper brackets. Hope it helps.

Have you tried this?

$('.myClass, .myOtherClass').removeClass('theclass');

You are accesing localhost, meaning you have a web server running on your machine. To access it from Internet, you need to assign a public IP address to your machine. Then you can access http://<public_ip>:<port>/. Port number is normally 80.

I do not have factual evidence to prove this but I already ran into this issue. It seems that triggering a click() event on an <a> tag doesn't seem to behave the same way you would expect with say, a input button.

The workaround I employed was to set the location.href property on the window which causes the browser to load the request resource like so:

$(document).ready(function()
{
      var href = $('.cssbuttongo').attr('href');
      window.location.href = href; //causes the browser to refresh and load the requested url
   });
});

Edit:

I would make a js fiddle but the nature of the question intermixed with how jsfiddle uses an iframe to render code makes that a no go.

Just tried this rule, and it worked with GoDaddy hosting since they've already have the Microsoft URL Rewriting module installed for every IIS 7 account.

If you're not bound to curl, you might want to use wget in recursive mode but restricting it to one level of recursion, try the following;

wget --no-verbose --no-parent --recursive --level=1\
--no-directories --user=login --password=pass ftp://ftp.myftpsite.com/

• --no-parent : Do not ever ascend to the parent directory when retrieving recursively.
• --level=depth : Specify recursion maximum depth level depth. The default maximum depth is five layers.
• --no-directories : Do not create a hierarchy of directories when retrieving recursively.

The typical solution to this is to write your own function to clone an object. If you are able to provide copy constructors and copy assignement operators, this may be as far as you need to go.

class Foo
{ 
public:
  Foo();
  Foo(const Foo& rhs) { /* copy construction from rhs*/ }
  Foo& operator=(const Foo& rhs) {};
};

// ...

Foo orig;
Foo copy = orig;  // clones orig if implemented correctly

Sometimes it is beneficial to provide an explicit clone() method, especially for polymorphic classes.

class Interface
{
public:
  virtual Interface* clone() const = 0;
};

class Foo : public Interface
{
public:
  Interface* clone() const { return new Foo(*this); }
};

class Bar : public Interface
{
public:
  Interface* clone() const { return new Bar(*this); }
};


Interface* my_foo = /* somehow construct either a Foo or a Bar */;
Interface* copy = my_foo->clone();

EDIT: Since Stack has no member variables, there's nothing to do in the copy constructor or copy assignment operator to initialize Stack's members from the so-called "right hand side" (rhs). However, you still need to ensure that any base classes are given the opportunity to initialize their members.

You do this by calling the base class:

Stack(const Stack& rhs) 
: List(rhs)  // calls copy ctor of List class
{
}

Stack& operator=(const Stack& rhs) 
{
  List::operator=(rhs);
  return * this;
};

The filter design method in accepted answer is correct, but it has a flaw. SciPy bandpass filters designed with b, a are unstable and may result in erroneous filters at higher filter orders.

Instead, use sos (second-order sections) output of filter design.

from scipy.signal import butter, sosfilt, sosfreqz

def butter_bandpass(lowcut, highcut, fs, order=5):
        nyq = 0.5 * fs
        low = lowcut / nyq
        high = highcut / nyq
        sos = butter(order, [low, high], analog=False, btype='band', output='sos')
        return sos

def butter_bandpass_filter(data, lowcut, highcut, fs, order=5):
        sos = butter_bandpass(lowcut, highcut, fs, order=order)
        y = sosfilt(sos, data)
        return y

Also, you can plot frequency response by changing

b, a = butter_bandpass(lowcut, highcut, fs, order=order)
w, h = freqz(b, a, worN=2000)

to

sos = butter_bandpass(lowcut, highcut, fs, order=order)
w, h = sosfreqz(sos, worN=2000)

If you don't care about the type of the numbers you can simply use:

qs[0].values()

Even better than Ran's suggestion of using GetProcAddress, simply make the call to LoadLibrary before any calls to the DllImport functions (with only a filename without a path) and they'll use the loaded module automatically.

I've used this method to choose at runtime whether to load a 32-bit or 64-bit native DLL without having to modify a bunch of P/Invoke-d functions. Stick the loading code in a static constructor for the type that has the imported functions and it'll all work fine.

//start use session

$session_start();

extract($_POST);         
//extract data from submit post 

if(isset($submit))  
{

if($user=="user" && $pass=="pass")

{

$_SESSION['user']= $user;   

//if correct password and name store in session 

}
else {

echo "Invalid user and password";

header("Locatin:form.php");

}

if(isset($_SESSION['user'])) 

{

//your home page code here

exit;
}

Set up a simple repository using a web server with its default configuration. The key is the directory structure. The documentation does not mention it explicitly, but it is the same structure as a local repository.

To set up an internal repository just requires that you have a place to put it, and then start copying required artifacts there using the same layout as in a remote repository such as repo.maven.apache.org. Source

Add a file to your repository like this:

mvn install:install-file \
  -Dfile=YOUR_JAR.jar -DgroupId=YOUR_GROUP_ID 
  -DartifactId=YOUR_ARTIFACT_ID -Dversion=YOUR_VERSION \
  -Dpackaging=jar \
  -DlocalRepositoryPath=/var/www/html/mavenRepository

If your domain is example.com and the root directory of the web server is located at /var/www/html/, then maven can find "YOUR_JAR.jar" if configured with <url>http://example.com/mavenRepository</url>.

As others have mentioned, perhaps the main advantage of matrix was that it provided a convenient notation for matrix multiplication.

However, in Python 3.5 there is finally a dedicated infix operator for matrix multiplication: @.

With recent NumPy versions, it can be used with ndarrays:

A = numpy.ones((1, 3))
B = numpy.ones((3, 3))
A @ B

So nowadays, even more, when in doubt, you should stick to ndarray.

In my case the validation itself was working (I could validate an element and retrieve a correct boolean value), but there was no visual output.

My fault was that I forgot this line @Html.ValidationMessageFor(m => ...)

The TS has this in his code and got me on the right track, but I put it in here as reference for others.

Because in Python 3, print statement has been replaced with a print() function, with keyword arguments to replace most of the special syntax of the old print statement. So you have to write it as

print("Hello World")

But if you write this in a program and someone using Python 2.x tries to run it, they will get an error. To avoid this, it is a good practice to import print function:

from __future__ import print_function

Now your code works on both 2.x & 3.x.

Check out below examples also to get familiar with print() function.

Old: print "The answer is", 2*2
New: print("The answer is", 2*2)

Old: print x,           # Trailing comma suppresses newline
New: print(x, end=" ")  # Appends a space instead of a newline

Old: print              # Prints a newline
New: print()            # You must call the function!

Old: print >>sys.stderr, "fatal error"
New: print("fatal error", file=sys.stderr)

Old: print (x, y)       # prints repr((x, y))
New: print((x, y))      # Not the same as print(x, y)!

How about this way:

List<int> myList = new List<int>(){1, 2, 3, 4}; //or any other type
myList.Sort();
int greatestValue = myList[ myList.Count - 1 ];

You basically let the Sort() method to do the job for you instead of writing your own method. Unless you don't want to sort your collection.

You should use this example with AUTHID CURRENT_USER :

CREATE OR REPLACE PROCEDURE Create_sequence_for_tab (VAR_TAB_NAME IN VARCHAR2)
   AUTHID CURRENT_USER
IS
   SEQ_NAME       VARCHAR2 (100);
   FINAL_QUERY    VARCHAR2 (100);
   COUNT_NUMBER   NUMBER := 0;
   cur_id         NUMBER;
BEGIN
   SEQ_NAME := 'SEQ_' || VAR_TAB_NAME;

   SELECT COUNT (*)
     INTO COUNT_NUMBER
     FROM USER_SEQUENCES
    WHERE SEQUENCE_NAME = SEQ_NAME;

   DBMS_OUTPUT.PUT_LINE (SEQ_NAME || '>' || COUNT_NUMBER);

   IF COUNT_NUMBER = 0
   THEN
      --DBMS_OUTPUT.PUT_LINE('DROP SEQUENCE ' || SEQ_NAME);
      -- EXECUTE IMMEDIATE 'DROP SEQUENCE ' || SEQ_NAME;
      -- ELSE
      SELECT 'CREATE SEQUENCE COMPTABILITE.' || SEQ_NAME || ' START WITH ' || ROUND (DBMS_RANDOM.VALUE (100000000000, 999999999999), 0) || ' INCREMENT BY 1'
        INTO FINAL_QUERY
        FROM DUAL;

      DBMS_OUTPUT.PUT_LINE (FINAL_QUERY);
      cur_id := DBMS_SQL.OPEN_CURSOR;
      DBMS_SQL.parse (cur_id, FINAL_QUERY, DBMS_SQL.v7);
      DBMS_SQL.CLOSE_CURSOR (cur_id);
   -- EXECUTE IMMEDIATE FINAL_QUERY;

   END IF;

   COMMIT;
END;

<ListView android:id="@+id/listView" ... />
<TextView android:id="@+id/empty" ... />
and in the linked Activity:

this.listView = (ListView) findViewById(R.id.listView);
this.listView.setEmptyView(findViewById(R.id.empty));

This works clearly with FragmentActivity if you are using the support library. Tested this by building for API 17 i.e. 4.2.2 image.

If you are using Jupyter in anaconda, after conda update scikit-learn in terminal, close anaconda and restart, otherwise the error will occur again.

You also could set both parameters like,

mMap.moveCamera( CameraUpdateFactory.newLatLngZoom(new LatLng(21.000000, -101.400000) ,4) );

This locates your map on a specific position and zoom. I use this on the setting up my map.

I found a way of resizing font size according to div size, without any JavaScript. I don't know how much efficient it's, but it nicely gets the job done.

Embed a SVG element inside the required div, and then use a foreignObject tag inside which you can use HTML elements. A sample code snippet that got my job done is given below.

<!-- The SVG element given below should be place inside required div tag -->
<svg viewBox='0 2 108.5 29' xmlns='http://www.w3.org/2000/svg'>
    <!-- The below tag allows adding HTML elements inside SVG tag -->
    <foreignObject x='5' y='0' width='93.5%' height='100%'>
        <!-- The below tag can be styled using CSS classes or style attributes -->
        <div xmlns='http://www.w3.org/1999/xhtml' style='text-overflow: ellipsis; overflow: hidden; white-space: nowrap;'>
            Required text goes here            
        </div>
    </foreignObject>
</svg>

All the viewBox, x, y, width and height values can be changed according to requirement.

Text can be defined inside the SVG element itself, but when the text overflows, ellipsis can't be added to SVG text. So, HTML element(s) are defined inside a foreignObject element, and text-overflow styles are added to that/those element(s).

Yes. I recommend you check out Kimberly Tripp's articles on indexing.

If an index is "covering", then there is no need to use anything but the index. In SQL Server 2005, you can also add additional columns to the index that are not part of the key which can eliminate trips to the rest of the row.

Having multiple indexes, each on a single column may mean that only one index gets used at all - you will have to refer to the execution plan to see what effects different indexing schemes offer.

You can also use the tuning wizard to help determine what indexes would make a given query or workload perform the best.

To answer your updated question you can do

String[] lines = ("Name =              Bob\n" +
        "Age =               27\n" +
        "Occupation =        Student\n" +
        "Status =            Single").split("\n");

for (String line : lines) {
    String[] parts = line.split(" = +");
    System.out.printf("%-19s %s%n", parts[0] + " =", parts[1]);
}

prints

Name =              Bob
Age =               27
Occupation =        Student
Status =            Single

You need to add this at start of your php page "login.php"

<?php header('Access-Control-Allow-Origin: *'); ?>

$('#table_id').dataTable({    
    "bInfo": false, //Dont display info e.g. "Showing 1 to 4 of 4 entries"
    "paging": false,//Dont want paging                
    "bPaginate": false,//Dont want paging      
})

Try this code

This will give a generator of working days, of course without holidays, stop is datetime.datetime object. If you need holidays just make additional argument with list of holidays and check with 'IFology' ;-)

def workingdays(stop, start=datetime.date.today()):
    while start != stop:
        if start.weekday() < 5:
            yield start
        start += datetime.timedelta(1)

Later on you can count them like

workdays = workingdays(datetime.datetime(2015, 8, 8))
len(list(workdays))

Although many year ago, clsocket seems a really nice small cross-platform (Windows, Linux, Mac OSX): https://github.com/DFHack/clsocket

You create handler in background thread this way

private void createHandler() {
        Thread thread = new Thread() {
          public void run() {
               Looper.prepare();

               final Handler handler = new Handler();
               handler.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                       // Do Work
                        handler.removeCallbacks(this);
                        Looper.myLooper().quit();
                   }
                }, 2000);

                Looper.loop();
            }
        };
        thread.start();
    }

/^[a-zA-Z]+$/ 

Off the top of my head.

Edit:

Or if you don't like the weird looking literal syntax you can do it like this

new RegExp("^[a-zA-Z]+$");

"Old school javascript" to the rescue (for those who aren't familiar/in love of functional programming)

for (let i = 0; i < someArray.length ; i++) {
  let item = someArray[i];
}

For cleaning Immediate window I use (VBA Excel 2016) next function:

Private Sub ClrImmediate()
   With Application.VBE.Windows("Immediate")
       .SetFocus
       Application.SendKeys "^g", True
       Application.SendKeys "^a", True
       Application.SendKeys "{DEL}", True
   End With
End Sub

But direct call of ClrImmediate() like this:

Sub ShowCommandBarNames()
    ClrImmediate
 '--   DoEvents    
    Debug.Print "next..."
End Sub

works only if i put the breakpoint on Debug.Print, otherwise the clearing will be done after execution of ShowCommandBarNames() - NOT before Debug.Print. Unfortunately, call of DoEvents() did not help me... And no matter: TRUE or FALSE is set for SendKeys.

To solve this I use next couple of calls:

Sub ShowCommandBarNames()
 '--    ClrImmediate
    Debug.Print "next..."
End Sub

Sub start_ShowCommandBarNames()
   ClrImmediate
   Application.OnTime Now + TimeSerial(0, 0, 1), "ShowCommandBarNames"
End Sub

It seems to me that using Application.OnTime might be very useful in programming for VBA IDE. In this case it's can be used even TimeSerial(0, 0, 0).

This is the correct way for getting the correct output.... However, childs parent id maybe sometimes printed as 1 because parent process gets terminated and the root process with pid = 1 controls this orphan process.

Found this on HTML table: keep the same width for columns

If you set the style table-layout: fixed; on your table, you can override the browser's automatic column resizing. The browser will then set column widths based on the width of cells in the first row of the table. Change your to and remove the inside of it, and then set fixed widths for the cells in .

This is one of the biggest sources of confusion with VB.Net, IMO.

Nothing in VB.Net is the equivalent of default(T) in C#: the default value for the given type.

• For value types, this is essentially the equivalent of 'zero': 0 for Integer, False for Boolean, DateTime.MinValue for DateTime, ...
• For reference types, it is the null value (a reference that refers to, well, nothing).

The statement d Is Nothing is therefore equivalent to d Is DateTime.MinValue, which obviously does not compile.

Solutions: as others have said

• Either use DateTime? (i.e. Nullable(Of DateTime)). This is my preferred solution.
• Or use d = DateTime.MinValue or equivalently d = Nothing

In the context of the original code, you could use:

Dim d As DateTime? = Nothing
Dim boolNotSet As Boolean = d.HasValue

A more comprehensive explanation can be found on Anthony D. Green's blog

The below is my code from reading text file to excel file.

Sub openteatfile()
Dim i As Long, j As Long
Dim filepath As String
filepath = "C:\Users\TarunReddyNuthula\Desktop\sample.ctxt"
ThisWorkbook.Worksheets("Sheet4").Range("Al:L20").ClearContents
Open filepath For Input As #1
i = l
Do Until EOF(1)
Line Input #1, linefromfile
lineitems = Split(linefromfile, "|")
        For j = LBound(lineitems) To UBound(lineitems)
            ThisWorkbook.Worksheets("Sheet4").Cells(i, j + 1).value = lineitems(j)
        Next j
    i = i + 1 
Loop
Close #1
End Sub

there is configuration in the following way:

Preferences -> keys -> Navigation shortcuts

the 3rd option: shortcut to choose a split pane is "no shortcut" by default, we can choose one

Encoding an image to base64 will make it about 30% bigger.

See the details in the wikipedia article about the Data URI scheme, where it states:

Base64-encoded data URIs are 1/3 larger in size than their binary equivalent. (However, this overhead is reduced to 2-3% if the HTTP server compresses the response using gzip)

The above error is a linker error... the linker a program that takes one or more objects generated by a compiler and combines them into a single executable program.

You must add -lboost_system to you linker flags which indicates to the linker that it must look for symbols like boost::system::system_category() in the library libboost_system.so.

If you have main.cpp, either:

g++ main.cpp -o main -lboost_system

OR

g++ -c -o main.o main.cpp
g++ main.o -lboost_system

Deleting the project specific settings files (Eclipse workspace/project folder/.settings/) from the project folder also will do. Obviously, we need to do a project clean and build after deleting.

I included the binary into my projects resources directory like so:

src\main\resources\chrome\chromedriver_win32.zip
src\main\resources\chrome\chromedriver_mac64.zip
src\main\resources\chrome\chromedriver_linux64.zip

Code:

import org.apache.commons.io.IOUtils;
import org.apache.commons.lang3.SystemUtils;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

import java.io.*;
import java.nio.file.Files;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;

public WebDriver getWebDriver() throws IOException {
    File tempDir = Files.createTempDirectory("chromedriver").toFile();
    tempDir.deleteOnExit();
    File chromeDriverExecutable;

    final String zipResource;
    if (SystemUtils.IS_OS_WINDOWS) {
        zipResource = "chromedriver_win32.zip";
    } else if (SystemUtils.IS_OS_LINUX) {
        zipResource = "chromedriver_linux64.zip";
    } else if (SystemUtils.IS_OS_MAC) {
        zipResource = "chrome/chromedriver_mac64.zip";
    } else {
        throw new RuntimeException("Unsuppoerted OS");
    }

    try (InputStream is = getClass().getResourceAsStream("/chrome/" + zipResource)) {
        try (ZipInputStream zis = new ZipInputStream(is)) {
            ZipEntry entry;
            entry = zis.getNextEntry();
            chromeDriverExecutable = new File(tempDir, entry.getName());
            chromeDriverExecutable.deleteOnExit();
            try (OutputStream out = new FileOutputStream(chromeDriverExecutable)) {
                IOUtils.copy(zis, out);
            }
        }
    }

    System.setProperty("webdriver.chrome.driver", chromeDriverExecutable.getAbsolutePath());
    return new ChromeDriver();
}

simply do the select:

Select * From Times
WHERE (StartDate <= @Date) AND (EndDate >= @Date) AND
((@day = 'Monday' AND (Monday = 1))
OR (@day = 'Tuesday' AND (Tuesday = 1))
OR (Wednesday = 1))

Copy the default devices.xml file from : /home/user/android-sdk/tools/lib/devices.xml

and paste it in the below paths: /android-sdk/system-images/android-22/android-wear/armeabi-v7a/ and /android-sdk/system-images/android-22/android-wear/x86/

This is a alternative solution, however, before replacing the devices.xml, take backup of the existing devices.xml file in these folders.

You either need to specify an ID in the insert, or you need to configure the id column in the database to have Identity Specification = Yes.

Since I am currently in development mode I set useSSL to No not in tomcat but in mysql server configurations. Went to Manage Access Settings\Manage Server Connections from workbench -> Selected my connection. Inside connection tab went to SSL tab and disabled the settings. Worked for me.

I m using the followung code and its working fine for me .

private void sendNotification(String msg) {
    Log.d(TAG, "Preparing to send notification...: " + msg);
    mNotificationManager = (NotificationManager) this
            .getSystemService(Context.NOTIFICATION_SERVICE);

    PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
            new Intent(this, MainActivity.class), 0);

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
            this).setSmallIcon(R.drawable.ic_launcher)
            .setContentTitle("GCM Notification")
            .setAutoCancel(true)
            .setDefaults(Notification.DEFAULT_ALL)
            .setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
            .setContentText(msg);

    mBuilder.setContentIntent(contentIntent);
    mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
    Log.d(TAG, "Notification sent successfully.");
}

You can add functionality to an Array by extending its prototype object.

Array.prototype.nullify = function( n ) {
    n = n >>> 0;
    for( var i = 0; i < n; ++i ) {
        this[ i ] = null;
    }
    return this;
};

Then:

var arr = [].nullify(9);

or:

var arr = [].nullify(9).map(function() { return [].nullify(9); });

ArrayList<String>[][] list = new ArrayList[10][10];
list[0][0] = new ArrayList<>();
list[0][0].add("test");

For boolean fields in Rails 3.2.6 at least, this will work in your migration.

def change
  add_column :users, :eula_accepted, :boolean, default: false
end

Putting a 1 or 0 for a default will not work here, since it is a boolean field. It must be a true or false value.

Thread interruption is based on flag interrupt status. For every thread default value of interrupt status is set to false. Whenever interrupt() method is called on thread, interrupt status is set to true.

1. If interrupt status = true (interrupt() already called on thread), that particular thread cannot go to sleep. If sleep is called on that thread interrupted exception is thrown. After throwing exception again flag is set to false.
2. If thread is already sleeping and interrupt() is called, thread will come out of sleeping state and throw interrupted Exception.

You should use the ClearContents method if you want to clear the content but preserve the formatting.

Worksheets("Sheet1").Range("A1:G37").ClearContents

To get the position look at the OnMouseMove event. The MouseEventArgs will give you the x an y positions...

protected override void OnMouseMove(MouseEventArgs mouseEv) 

To set the mouse position use the Cursor.Position property.

You can do a post/get using a library which allows you to use HttpClient with strongly-typed callbacks.

The data and the error are available directly via these callbacks.

The library is called angular-extended-http-client.

angular-extended-http-client library on GitHub

angular-extended-http-client library on NPM

Very easy to use.

Traditional approach

In the traditional approach you return Observable<HttpResponse<T>> from Service API. This is tied to HttpResponse.

With this approach you have to use .subscribe(x => ...) in the rest of your code.

This creates a tight coupling between the http layer and the rest of your code.

Strongly-typed callback approach

You only deal with your Models in these strongly-typed callbacks.

Hence, The rest of your code only knows about your Models.

Sample usage

The strongly-typed callbacks are

Success:

• IObservable<T>
• IObservableHttpResponse
• IObservableHttpCustomResponse<T>

Failure:

• IObservableError<TError>
• IObservableHttpError
• IObservableHttpCustomError<TError>

Add package to your project and in your app module

import { HttpClientExtModule } from 'angular-extended-http-client';

and in the @NgModule imports

  imports: [
    .
    .
    .
    HttpClientExtModule
  ],

Your Models

export class SearchModel {
    code: string;
}

//Normal response returned by the API.
export class RacingResponse {
    result: RacingItem[];
}

//Custom exception thrown by the API.
export class APIException {
    className: string;
}

Your Service

In your Service, you just create params with these callback types.

Then, pass them on to the HttpClientExt's get method.

import { Injectable, Inject } from '@angular/core'
import { SearchModel, RacingResponse, APIException } from '../models/models'
import { HttpClientExt, IObservable, IObservableError, ResponseType, ErrorType } from 'angular-extended-http-client';
.
.

@Injectable()
export class RacingService {

    //Inject HttpClientExt component.
    constructor(private client: HttpClientExt, @Inject(APP_CONFIG) private config: AppConfig) {

    }

    //Declare params of type IObservable<T> and IObservableError<TError>.
    //These are the success and failure callbacks.
    //The success callback will return the response objects returned by the underlying HttpClient call.
    //The failure callback will return the error objects returned by the underlying HttpClient call.
    searchRaceInfo(model: SearchModel, success: IObservable<RacingResponse>, failure?: IObservableError<APIException>) {
        let url = this.config.apiEndpoint;

        this.client.post<SearchModel, RacingResponse>(url, model, 
                                                      ResponseType.IObservable, success, 
                                                      ErrorType.IObservableError, failure);
    }
}

Your Component

In your Component, your Service is injected and the searchRaceInfo API called as shown below.

  search() {    


    this.service.searchRaceInfo(this.searchModel, response => this.result = response.result,
                                                  error => this.errorMsg = error.className);

  }

Both, response and error returned in the callbacks are strongly typed. Eg. response is type RacingResponse and error is APIException.

You can use std::ifstream, funcion like is_open, fail, for example as below code (the cout "open" means file exist or not):

cited from this answer

You can use database from here -

http://myip.ms/info/cities_sql_database/

CREATE TABLE `cities` (
  `cityID` mediumint(8) unsigned NOT NULL AUTO_INCREMENT,
  `cityName` varchar(50) NOT NULL,
  `stateID` smallint(5) unsigned NOT NULL DEFAULT '0',
  `countryID` varchar(3) NOT NULL DEFAULT '',
  `language` varchar(10) NOT NULL DEFAULT '',
  `latitude` double NOT NULL DEFAULT '0',
  `longitude` double NOT NULL DEFAULT '0',
  PRIMARY KEY (`cityID`),
  UNIQUE KEY `unq` (`countryID`,`stateID`,`cityID`),
  KEY `cityName` (`cityName`),
  KEY `stateID` (`stateID`),
  KEY `countryID` (`countryID`),
  KEY `latitude` (`latitude`),
  KEY `longitude` (`longitude`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8;

PHP has JSON_PRETTY_PRINT option since 5.4.0 (release date 01-Mar-2012).

This should do the job:

$json = json_decode($string);
echo json_encode($json, JSON_PRETTY_PRINT);

See http://www.php.net/manual/en/function.json-encode.php

Note: Don't forget to echo "<pre>" before and "</pre>" after, if you're printing it in HTML to preserve formatting ;)

We can use CSS to hide the first option , But it wont work in IE 10, 11. The best way is to remove the element using Jquery. This solution works for major browser tested in chrome and IE10 ,11

Also if you are using angular , sometime using setTimeout works

$scope.RemoveFirstOptionElement = function (element) {
    setTimeout(function () {
        $(element.children()[0]).remove();
    }, 0);
};

When looking for the max performance you run into a lot of issue and potential bottlenecks. Running a simple hello world test is not necessarily going to find them all.

Possible limitations include:

• Kernel socket limitations: look in /proc/sys/net for lots of kernel tuning..
• process limits: check out ulimit as others have stated here
• as your application grows in complexity, it may not have enough CPU power to keep up with the number of connections coming in. Use top to see if your CPU is maxed
• number of threads? I'm not experienced with threading, but this may come into play in conjunction with the previous items.

I originally found this post looking for a solution to copying stored procedures from my remote production database to my local development database. After success using the suggested approach in this thread, I realized I grew increasingly lazy (or resourceful, whichever you prefer) and wanted this to be automated.

I have a .bat file that calls this, and is called from Task Scheduler. After the call to the Powershell file, I have:

for /f %f in ('dir /b d:\prod_schema_backup\stp\') do sqlcmd /S localhost /d dest_db /Q "DROP PROCEDURE %f"

That line will go thru the directory and drop the procedures it is going to recreate. If this wasn't a development environment, I would not like programmatically dropping procedures this way. I then rename all the stored procedure files to have .sql:

powershell Dir d:\prod_schema_backup\stp\ | Rename-Item -NewName { $_.name + ".sql" }

And then run:

for /f %f in ('dir /b d:\prod_schema_backup\stp\') do sqlcmd /S localhost /d dest_db /E /i "%f".sql

And that iterates through all the .sql files and recreates the stored procedures. I hope that any part of this will prove to be helpful to someone.

Have you tried to specify UserAgent for your request? For example:

request.UserAgent = "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)";

For an extensive coverage review the contents of RFC2965. Of course that doesn't necessarily mean that all browsers behave exactly the same way.

However in general the rule for default Path if none specified in the cookie is the path in the URL from which the Set-Cookie header arrived. Similarly the default for the Domain is the full host name in the URL from which the Set-Cookie arrived.

Matching rules for the domain require the cookie Domain to match the host to which the request is being made. The cookie can specify a wider domain match by include *. in the domain attribute of Set-Cookie (this one area that browsers may vary). Matching the path (assuming the domain matches) is a simple matter that the requested path must be inside the path specified on the cookie. Typically session cookies are set with path=/ or path=/applicationName/ so the cookie is available to all requests into the application.

• Will a cookie for .example.com be available for www.example.com? Yes
• Will a cookie for .example.com be available for example.com? Don't Know
• Will a cookie for example.com be available for www.example.com? Shouldn't but... *
• Will a cookie for example.com be available for anotherexample.com? No
• Will www.example.com be able to set cookie for example.com? Yes
• Will www.example.com be able to set cookie for www2.example.com? No (Except via .example.com)
• Will www.example.com be able to set cookie for .com? No (Can't set a cookie this high up the namespace nor can you set one for something like .co.uk).

* I'm unable to test this right now but I have an inkling that at least IE7/6 would treat the path example.com as if it were .example.com.

People are saying that the symbol doesn't mean addition. This is true, but doesn't explain why a plus-like symbol is used for something that isn't addition.

The answer is that for modulo addition of 1-bit values, 0+0 == 1+1 == 0, and 0+1 == 1+0 == 1. Those are the same values as XOR.

So, plus in a circle in this context means "bitwise addition modulo-2". Which is, as everyone says, XOR for integers. It's common in mathematics to use plus in a circle for an operation which is a sort of addition, but isn't regular integer addition.

To get substring

1. find position of "sp"

2. cut string with array-logical

I know this is late to the game, and the question has been answered very well already, but I want to offer my opinion on #3 regarding the prefixing of column names.

All columns should be named with a prefix that is unique to the table they are defined in.

E.g. Given tables "customer" and "address", let's go with prefixes of "cust" and "addr", respectively. "customer" would have "cust_id", "cust_name", etc. in it. "address" would have "addr_id", "addr_cust_id" (FK back to customer), "addr_street", etc. in it.

When I was first presented with this standard, I was dead-set against it; I hated the idea. I couldn't stand the idea of all that extra typing and redundancy. Now I've had enough experience with it that I'd never go back.

The result of doing this is that all of the columns in your database schema are unique. There is one major benefit to this, which trumps all arguments against it (in my opinion, of course):

You can search your entire code base and reliably find every line of code that touches a particular column.

The benefit from #1 is incredibly huge. I can deprecate a column and know exactly what files need to be updated before the column can safely be removed from the schema. I can change the meaning of a column and know exactly what code needs to be refactored. Or I can simply tell if data from a column is even being used in a particular portion of the system. I can't count the number of times this has turned a potentially huge project into a simple one, nor the amount of hours we've saved in development work.

Another, relatively minor benefit to it is that you only have to use table-aliases when you do a self join:

SELECT cust_id, cust_name, addr_street, addr_city, addr_state
    FROM customer
        INNER JOIN address ON addr_cust_id = cust_id
    WHERE cust_name LIKE 'J%';

Until Safari implements Service Worker and follows the direction set by Chrome and Firefox, there is no way to add your app programatically to the home screen, or to have the browser prompt the user

However, there is a small library that prompts the user to do it and even points to the right spot. Works a treat.

https://github.com/cubiq/add-to-homescreen

You can return to the same existing instance of Activity with android:launchMode="singleInstance"

in the manifest. When you return to A from B, may be needed finish() to destroy B.

A MD5 hash is 128 bits, so you can't represent it in hex with less than 32 characters...

Use:

document.location.href = "http://yoursite.com" + document.getElementById('somefield');

That would get the value of some text field or hidden field, and add it to your site URL to get a new URL (href). You can modify this to suit your needs.

If you have an object and wish to become JObject you can use:

JObject o = (JObject)JToken.FromObject(miObjetoEspecial);

like this :

Pocion pocionDeVida = new Pocion{
tipo = "vida",
duracion = 32,
};

JObject o = (JObject)JToken.FromObject(pocionDeVida);
Console.WriteLine(o.ToString());
// {"tipo": "vida", "duracion": 32,}

I posted an answer to this already when someone else asked the same question (see How to bring back "Browser mode" in IE11?).

Read my answer there for a fuller explaination, but in short:

• They removed it deliberately, because compat mode is not actually really very good for testing compatibility.

• If you really want to test for compatibility with any given version of IE, you need to test in a real copy of that IE version. MS provide free VMs on http://modern.ie/ for you to use for this purpose.

• The only way to get compat mode in IE11 is to set the X-UA-Compatible header. When you have this and the site defaults to compat mode, you will be able to set the mode in dev tools, but only between edge or the specified compat mode; other modes will still not be available.

Quicktime movs exported as animation work but in safari only. I wish there was a complete solution (or format) that covered all major browsers.

You don't. While PHP offers lots of ways to call a URL, it doesn't offer out of the box support for doing any kind of asynchronous/threaded processing per request/execution cycle. Any method of sending a request for a URL (or a SQL statement, or a etc.) is going to wait for some kind of response. You'll need some kind of secondary system running on the local machine to achieve this (google around for "php job queue")

PowerShell has really wacky return semantics - at least when viewed from a more traditional programming perspective. There are two main ideas to wrap your head around:

• All output is captured, and returned
• The return keyword really just indicates a logical exit point

Thus, the following two script blocks will do effectively the exact same thing:

$a = "Hello, World"
return $a

$a = "Hello, World"
$a
return

The $a variable in the second example is left as output on the pipeline and, as mentioned, all output is returned. In fact, in the second example you could omit the return entirely and you would get the same behavior (the return would be implied as the function naturally completes and exits).

Without more of your function definition I can't say why you are getting a PSMethod object. My guess is that you probably have something a few lines up that is not being captured and is being placed on the output pipeline.

It is also worth noting that you probably don't need those semicolons - unless you are nesting multiple expressions on a single line.

You can read more about the return semantics on the about_Return page on TechNet, or by invoking the help return command from PowerShell itself.

Alternatively, you can add it to the URL and let the scripting language (PHP, Perl, ASP, Python, Ruby, whatever) handle it on the other side. Something like:

var x = 10;
window.open('mypage.php?x='+x);

Try setting the initial value when you instantiate the form:

form = MyForm(initial={'max_number': '3'})

add some css:

td, th {
   border:none;
}

There is no explicit way to change the favicon globally using CSS that I know of. But you can use a simple trick to change it on the fly.

First just name, or rename, the favicon to "favicon.ico" or something similar that will be easy to remember, or is relevant for the site you're working on. Then add the link to the favicon in the head as you usually would. Then when you drop in a new favicon just make sure it's in the same directory as the old one, and that it has the same name, and there you go!

It's not a very elegant solution, and it requires some effort. But dropping in a new favicon in one place is far easier than doing a find and replace of all the links, or worse, changing them manually. At least this way doesn't involve messing with the code.

Of course dropping in a new favicon with the same name will delete the old one, so make sure to backup the old favicon in case of disaster, or if you ever want to go back to the old design.

Jezus, all this programming for just an index restart... Perhaps I'm an idiot, but for pre-oracle 12 (which has a restart feature), what is wrong with a simpel:

drop sequence blah;
create sequence blah 

?

Or use the XmlSerializer class.

XmlSerializer xs = new XmlSerializer(objectType);
obj = xs.Deserialize(new StringReader(yourXmlString));

In case you do not know the usernames as created here. You can get the users as described by @FallenAngel above.

python manage.py shell 
from django.contrib.auth.models import User
usrs = User.objects.filter(is_superuser=True)
#identify the user
your_user = usrs.filter(username="yourusername")[0]
#youruser = usrs.get(username="yourusername")
#then set the password

However in the event that you created your independent user model. A simple case is when you want to use email as a username instead of the default user name. In which case your user model lives somewhere such as your_accounts_app.models then the above solution wont work. In this case you can instead use the get_user_model method

from django.contrib.auth import get_user_model 
super_users = get_user_model().objects.filter(is_superuser=True)
#proceed to get identify your user
# and set their user password

I had the same problem, but believe it or not is was a case of case sensitivity.

This on localhost: http://localhost/.../getdata.php?id=3

Did not behave the same as this on the server: http://server/.../getdata.php?id=3

Changing the server url to this (notice the capital D in getData) solved my issue. http://localhost/.../getData.php?id=3

Were you expecting player to be a dict rather than a list?

UIImageView *imageView = [UIImageView alloc]init];
imageView.layer.masksToBounds = YES;
imageView.layer.borderColor = [UIColor blackColor].CGColor;
imageView.layer.borderWidth = 1;    

This code can be used for adding UIImageView view border.

If your model is called BlogPost, it would be:

BlogPost.all.map(&:destroy)

You can connect IBOutlet of yur button from storyboard.

Then you can set corner radius of your button to make it's corner round.

for example, your outlet is myButton then,

Obj - C

 self.myButton.layer.cornerRadius = 5.0 ;

Swift

  myButton.layer.cornerRadius = 5.0

If you want exact round button then your button's width and height must be equal and cornerRadius must be equal to height or width / 2 (half of the width or height).

Of course. The whole idea of abstract classes is that they can contain some behaviour or data which you require all sub-classes to contain. Think of the simple example of WheeledVehicle - it should have a numWheels member variable. You want all sub classes to have this variable. Remember that abstract classes are a very useful feature when developing APIs, as they can ensure that people who extend your API won't break it.

Try something like this:

#include <signal.h>

pid_t child_pid = -1 ; //Global

void kill_child(int sig)
{
    kill(child_pid,SIGKILL);
}

int main(int argc, char *argv[])
{
    signal(SIGALRM,(void (*)(int))kill_child);
    child_pid = fork();
    if (child_pid > 0) {
     /*PARENT*/
        alarm(30);
        /*
         * Do parent's tasks here.
         */
        wait(NULL);
    }
    else if (child_pid == 0){
     /*CHILD*/
        /*
         * Do child's tasks here.
         */
    }
}

To create a simple table using terminaltables

Open the terminal or your command prompt and run pip install terminaltables You can print and python list as the following

from terminaltables import AsciiTable

l = [
  ['Head', 'Head'],
  ['R1 C1', 'R1 C2'],
  ['R2 C1', 'R2 C2'],
  ['R3 C1', 'R3 C2']
]

table = AsciiTable(l)

print(table.table)

They have other cool tables don't forget to check them out. Just google their library.

Hope that helps :100:!

If you want to clean your database named "example_db":

1) Login to another db(for example 'postgres'):

psql postgres

2) Remove your database:

DROP DATABASE example_db;

3) Recreate your database:

CREATE DATABASE example_db;

Put your splash screen in a separate activity and use startActivityForResult from your main activity's onCreate method to display it. This works because, according to the docs:

As a special case, if you call startActivityForResult() with a requestCode >= 0 during the initial onCreate(Bundle savedInstanceState)/onResume() of your activity, then your window will not be displayed until a result is returned back from the started activity. This is to avoid visible flickering when redirecting to another activity.

You should probably do this only if the argument to onCreate is null (indicating a fresh launch of your activity, as opposed to a restart due to a configuration change).

Just ask yourself how many statements need to execute for F(n) to complete.

For F(1), the answer is 1 (the first part of the conditional).

For F(n), the answer is F(n-1) + F(n-2).

So what function satisfies these rules? Try aⁿ (a > 1):

aⁿ == a^(n-1) + a^(n-2)

Divide through by a^(n-2):

a² == a + 1

Solve for a and you get (1+sqrt(5))/2 = 1.6180339887, otherwise known as the golden ratio.

So it takes exponential time.

Build your own script to install global dependencies. It doesn't take much. package.json is quite expandable.

const {execSync} = require('child_process');

JSON.parse(fs.readFileSync('package.json'))
     .globalDependencies.foreach(
         globaldep => execSync('npm i -g ' + globaldep)
     );

Using the above, you can even make it inline, below!

Look at preinstall below:

{
  "name": "Project Name",
  "version": "0.1.0",
  "description": "Project Description",
  "main": "app.js",
  "scripts": {
    "preinstall": "node -e \"const {execSync} = require('child_process'); JSON.parse(fs.readFileSync('package.json')).globalDependencies.foreach(globaldep => execSync('npm i -g ' + globaldep));\"",
    "build": "your transpile/compile script",
    "start": "node app.js",
    "test": "./node_modules/.bin/mocha --reporter spec",
    "patch-release": "npm version patch && npm publish && git add . && git commit -m \"auto-commit\" && git push --follow-tags"
  },
  "dependencies": [
  },
  "globalDependencies": [
    "[email protected]",
    "ionic",
    "potato"
  ],
  "author": "author",
  "license": "MIT",
  "devDependencies": {
    "chai": "^4.2.0",
    "mocha": "^5.2.0"
  },
  "bin": {
    "app": "app.js"
  }
}

The authors of node may not admit package.json is a project file. But it is.

From your SQL Server Management Studio, you open Object Explorer, go to your database where you want to load the data into, right click, then pick Tasks > Import Data.

This opens the Import Data Wizard, which typically works pretty well for importing from Excel. You can pick an Excel file, pick what worksheet to import data from, you can choose what table to store it into, and what the columns are going to be. Pretty flexible indeed.

You can run this as a one-off, or you can store it as a SQL Server Integration Services (SSIS) package into your file system, or into SQL Server itself, and execute it over and over again (even scheduled to run at a given time, using SQL Agent).

Update: yes, yes, yes, you can do all those things you keep asking - have you even tried at least once to run that wizard??

OK, here it comes - step by step:

Step 1: pick your Excel source

Step 2: pick your SQL Server target database

Step 3: pick your source worksheet (from Excel) and your target table in your SQL Server database; see the "Edit Mappings" button!

Step 4: check (and change, if needed) your mappings of Excel columns to SQL Server columns in the table:

Step 5: if you want to use it later on, save your SSIS package to SQL Server:

Step 6: - success! This is on a 64-bit machine, works like a charm - just do it!!

Here is the simple solution with StreamEx

EntryStream.of(countByType).sortedBy(e -> e.getValue()).keys().toList();

If you are needing this to get user's home dir, below could be considered as portable (win32 and linux at least), part of a standard library.

>>> os.path.expanduser('~')
'C:\\Documents and Settings\\johnsmith'

Also you could parse such string to get only last path component (ie. user name).

See: os.path.expanduser

If you want to filter records for a particular year (e.g. 2000) then optimize the WHERE clause like this:

SELECT MONTH(date_column), COUNT(*)
FROM date_table
WHERE date_column >= '2000-01-01' AND date_column < '2001-01-01'
GROUP BY MONTH(date_column)
-- average 0.016 sec.

Instead of:

WHERE YEAR(date_column) = 2000
-- average 0.132 sec.

The results were generated against a table containing 300k rows and index on date column.

As for the GROUP BY clause, I tested the three variants against the above mentioned table; here are the results:

SELECT YEAR(date_column), MONTH(date_column), COUNT(*)
FROM date_table
GROUP BY YEAR(date_column), MONTH(date_column)
-- codelogic
-- average 0.250 sec.

SELECT YEAR(date_column), MONTH(date_column), COUNT(*)
FROM date_table
GROUP BY DATE_FORMAT(date_column, '%Y%m')
-- Andriy M
-- average 0.468 sec.

SELECT YEAR(date_column), MONTH(date_column), COUNT(*)
FROM date_table
GROUP BY EXTRACT(YEAR_MONTH FROM date_column)
-- fu-chi
-- average 0.203 sec.

The last one is the winner.

For me, I couldn't get this to return a hash.

results = ActiveRecord::Base.connection.execute(sql)

But using the exec_query method worked.

results = ActiveRecord::Base.connection.exec_query(sql)

You could try the following:

select customer1.Id,customer1.Name,customer1.city,CustAdd.phone,CustAdd.Country
from customer1
inner join [EBST08].[Test].[dbo].[customerAddress] CustAdd
on customer1.Id=CustAdd.CustId

I usually use keys and I can't think of the last time I used or read a use of each.

Don't forget about map, depending on what you're doing in the loop!

map { print "$_ => $hash{$_}\n" } keys %hash;

It will not work for first position so better solution is :

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

Check it by yourself. I have tested it for adding class for every 4th element.

They are slightly different - the ETag does not have any information that the client can use to determine whether or not to make a request for that file again in the future. If ETag is all it has, it will always have to make a request. However, when the server reads the ETag from the client request, the server can then determine whether to send the file (HTTP 200) or tell the client to just use their local copy (HTTP 304). An ETag is basically just a checksum for a file that semantically changes when the content of the file changes.

The Expires header is used by the client (and proxies/caches) to determine whether or not it even needs to make a request to the server at all. The closer you are to the Expires date, the more likely it is the client (or proxy) will make an HTTP request for that file from the server.

So really what you want to do is use BOTH headers - set the Expires header to a reasonable value based on how often the content changes. Then configure ETags to be sent so that when clients DO send a request to the server, it can more easily determine whether or not to send the file back.

One last note about ETag - if you are using a load-balanced server setup with multiple machines running Apache you will probably want to turn off ETag generation. This is because inodes are used as part of the ETag hash algorithm which will be different between the servers. You can configure Apache to not use inodes as part of the calculation but then you'd want to make sure the timestamps on the files are exactly the same, to ensure the same ETag gets generated for all servers.

A UDF will only return a value it won't allow you to change the properties of a cell/sheet/workbook. Move your code to a Worksheet_Change event or similar to change properties.

Eg

Private Sub worksheet_change(ByVal target As Range)
  target.Font.Bold = True
End Sub

I'd like to add df.values.tolist(). (as long as you don't mind to get a column of lists rather than tuples)

import pandas as pd
import numpy as np

size = int(1e+07)
df = pd.DataFrame({'a': np.random.rand(size), 'b': np.random.rand(size)}) 

%timeit df.values.tolist()
1.47 s ± 38.9 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

%timeit list(zip(df.a,df.b))
1.92 s ± 131 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

sudo gem install -n /usr/local/bin cocoapods

Try this. It will definately work.

I haven't used connect by prior, but a quick search shows it's used for tree structures. In SQL Server, you use common table expressions to get similar functionality.

I encountered this issue on a linuxmint distro. It appeared to have happened when there was so many folders and subfolders/files I added to the /public folder in my app. I applied this fix and it worked well...

$ echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf

change directory into the /etc folder: cd /etc

then run this: sudo systcl -p

You may have to close your terminal and npm start again to get it to work.

If this fails i recommend installing react-scripts globally and running your application directly with that.

$ npm i -g --save react-scripts

then instead of npm start run react-scripts start to run your application.

public class Ascii {
    public static void main(String [] args){
        String a=args[0];
        char [] z=a.toCharArray();
        for(int i=0;i<z.length;i++){ 
            System.out.println((int)z[i]);
        }
    }
}

It's been a 5+ years for this question but heay always welcome to the efficient ways of coding/scripting.

var n = 123456789;
var arrayN = (`${n}`).split("").map(e => parseInt(e))

Use this code to get Registration ID using GCM

String regId = "", msg = "";

public void getRegisterationID() {

    new AsyncTask() {
        @Override
        protected Object doInBackground(Object...params) {

            String msg = "";
            try {
                if (gcm == null) {
                    gcm = GoogleCloudMessaging.getInstance(Login.this);
                }
                regId = gcm.register(YOUR_SENDER_ID);
                Log.d("in async task", regId);

                // try
                msg = "Device registered, registration ID=" + regId;

            } catch (IOException ex) {
                msg = "Error :" + ex.getMessage();
            }
            return msg;
        }
    }.execute(null, null, null);
 }

and don't forget to write permissions in manifest...
I hope it helps!

For anyone who wants to do this in Swift 2.x:

self.navigationController?.navigationBar.setBackgroundImage(UIImage(), forBarMetrics: .Default)
self.navigationController?.navigationBar.shadowImage = UIImage()
self.navigationController?.navigationBar.translucent = true

or Swift 3.x:

self.navigationController?.navigationBar.setBackgroundImage(UIImage(), for: .default)
self.navigationController?.navigationBar.shadowImage = UIImage()
self.navigationController?.navigationBar.isTranslucent = true

You need to escape the backslash \:

println yourString.replace("\\", "/")

I just came across this as a really nice and elegant solution:

Math.random().toString(36).slice(2)

Notes on this implementation:

• This will produce a string anywhere between zero and 12 characters long, usually 11 characters, due to the fact that floating point stringification removes trailing zeros.
• It won't generate capital letters, only lower-case and numbers.
• Because the randomness comes from Math.random(), the output may be predictable and therefore not necessarily unique.
• Even assuming an ideal implementation, the output has at most 52 bits of entropy, which means you can expect a duplicate after around 70M strings generated.

eof() checks the eofbit in the stream state.

On each read operation, if the position is at the end of stream and more data has to be read, eofbit is set to true. Therefore you're going to get an extra character before you get eofbit=1.

The correct way is to check whether the eof was reached (or, whether the read operation succeeded) after the reading operation. This is what your second version does - you do a read operation, and then use the resulting stream object reference (which >> returns) as a boolean value, which results in check for fail().

Solution for this issue is:

1. Create another connection manager for your excel or flat files else you just have to pass variable values in connection string:

2. Right Click on Connection Manager>>properties>>Expression >>Select "ConnectionString" from drop down and pass the input variable like path , filename ..

You may consider using fps filter. It won't change the video playback speed:

ffmpeg -i <input> -filter:v fps=fps=30 <output>

Worked nice for reducing fps from 59.6 to 30.

I would use the shebang #!/usr/bin/python (first line of code) with the serial number of Python at the end ;)

Then run the Python file as a script, e.g., ./main.py from the command line, rather than python main.py.

It is the same when you want to run Python from a Linux command line.

I came across this recently, it certainly helped me understand: https://www.cs.ryerson.ca/~aharley/vis/conv/

So there's an input, a Conv2D, MaxPooling2D etc, the Flatten layers are at the end and show exactly how they are formed and how they go on to define the final classifications (0-9).

Also it may cause some warnigs in logs like a Cglib2AopProxy Unable to proxy method. And many other reasons for this are described here Why always have single implementaion interfaces in service and dao layers?

More simple,

echo $line | sed 's/\s/\n/g'

\s --> whitespace character (space, tab, NL, FF, VT, CR). In many systems also valid [:space:]

\n --> new line

As of Go1.1 release, there is a bufio.Scanner API that can easily read lines from a file. Consider the following example from above, rewritten with Scanner:

package main

import (
    "bufio"
    "fmt"
    "log"
    "os"
)

// readLines reads a whole file into memory
// and returns a slice of its lines.
func readLines(path string) ([]string, error) {
    file, err := os.Open(path)
    if err != nil {
        return nil, err
    }
    defer file.Close()

    var lines []string
    scanner := bufio.NewScanner(file)
    for scanner.Scan() {
        lines = append(lines, scanner.Text())
    }
    return lines, scanner.Err()
}

// writeLines writes the lines to the given file.
func writeLines(lines []string, path string) error {
    file, err := os.Create(path)
    if err != nil {
        return err
    }
    defer file.Close()

    w := bufio.NewWriter(file)
    for _, line := range lines {
        fmt.Fprintln(w, line)
    }
    return w.Flush()
}

func main() {
    lines, err := readLines("foo.in.txt")
    if err != nil {
        log.Fatalf("readLines: %s", err)
    }
    for i, line := range lines {
        fmt.Println(i, line)
    }

    if err := writeLines(lines, "foo.out.txt"); err != nil {
        log.Fatalf("writeLines: %s", err)
    }
}

async function (request, response, next) {
  const url = request.rawHeaders[9] + request.originalUrl;
  //or
  const url = request.headers.host + request.originalUrl;
}

You may use Request.Cookies collection to read the cookies.

if(Request.Cookies["key"]!=null)
{
   var value=Request.Cookies["key"].Value;
}

git bash is a shell where:

• the running process is sh.exe (packaged with msysgit, as share/WinGit/Git Bash.vbs)
• git is a known command
• $HOME is defined

See "Fix msysGit Portable $HOME location":

On a Windows 64:

C:\Windows\SysWOW64\cmd.exe /c ""C:\Prog\Git\1.7.1\bin\sh.exe" --login -i"

This differs from git-cmd.bat, which provides git commands in a plain DOS command prompt.

A tool like GitHub for Windows (G4W) provides different shell for git (including a PowerShell one)

Update April 2015:

Note: the git bash in msysgit/Git for windows 1.9.5 is an old one:

GNU bash, version 3.1.20(4)-release (i686-pc-msys)
Copyright (C) 2005 Free Software Foundation, Inc.

But with the phasing out of msysgit (Q4 2015) and the new Git For Windows (Q2 2015), you now have Git for Windows 2.3.5.
It has a much more recent bash, based on the 64bits msys2 project, an independent rewrite of MSYS, based on modern Cygwin (POSIX compatibility layer) and MinGW-w64 with the aim of better interoperability with native Windows software. msys2 comes with its own installer too.

The git bash is now (with the new Git For Windows):

GNU bash, version 4.3.33(3)-release (x86_64-pc-msys)
Copyright (C) 2013 Free Software Foundation, Inc.

Original answer (June 2013) More precisely, from msygit wiki:

Historically, Git on Windows was only officially supported using Cygwin.
To help make a native Windows version, this project was started, based on the mingw fork.

To make the milky 'soup' of project names more clear, we say like this:

• msysGit - is the name of this project, a build environment for Git for Windows, which releases the official binaries
• MinGW - is a minimalist development environment for native Microsoft Windows applications.
  It is really a very thin compile-time layer over the Microsoft Runtime; MinGW programs are therefore real Windows programs, with no concept of Unix-style paths or POSIX niceties such as a fork() call
• MSYS - is a Bourne Shell command line interpreter system, is used by MinGW (and others), was forked in the past from Cygwin
• Cygwin - a Linux like environment, which was used in the past to build Git for Windows, nowadays has no relation to msysGit

So, your two lines description about "git bash" are:

"Git bash" is a msys shell included in "Git for Windows", and is a slimmed-down version of Cygwin (an old version at that), whose only purpose is to provide enough of a POSIX layer to run a bash.

Reminder:

msysGit is the development environment to compile Git for Windows. It is complete, in the sense that you just need to install msysGit, and then you can build Git. Without installing any 3rd-party software.

msysGit is not Git for Windows; that is an installer which installs Git -- and only Git.

See more in "Difference between msysgit and Cygwin + git?".

Storing files in your database will lead to a huge database size. You may not like that, for development, testing, backups, etc.

Instead, you'd use FileStream (SQL-Server) or BFILE (Oracle).

There is no default-implementation of BFILE/FileStream in Postgres, but you can add it: https://github.com/darold/external_file

And further information (in french) can be obtained here:
http://blog.dalibo.com/2015/01/26/Extension_BFILE_pour_PostgreSQL.html

To answer the acual question:
Apart from bytea, for really large files, you can use LOBS:

                connection.Close();
        } // End Using trans 

    } // End Using connection

} // End Sub DeleteLargeObject 

You can do the following :-

$(document).ready(function(){
    $("#id").trigger("click");
});

The problem is this block:

using (var sr = new StreamReader(ms))
{
    Console.WriteLine(sr.ReadToEnd());                        
}

When the StreamReader is closed (after leaving the using), it closes it's underlying stream as well, so now the MemoryStream is closed. When the StreamWriter gets closed, it tries to flush everything to the MemoryStream, but it is closed.

You should consider not putting the StreamReader in a using block.

RESTful Resource controller

A RESTful resource controller sets up some default routes for you and even names them.

Route::resource('users', 'UsersController');

Gives you these named routes:

Verb          Path                        Action  Route Name
GET           /users                      index   users.index
GET           /users/create               create  users.create
POST          /users                      store   users.store
GET           /users/{user}               show    users.show
GET           /users/{user}/edit          edit    users.edit
PUT|PATCH     /users/{user}               update  users.update
DELETE        /users/{user}               destroy users.destroy

And you would set up your controller something like this (actions = methods)

class UsersController extends BaseController {

    public function index() {}

    public function show($id) {}

    public function store() {}

}

You can also choose what actions are included or excluded like this:

Route::resource('users', 'UsersController', [
    'only' => ['index', 'show']
]);

Route::resource('monkeys', 'MonkeysController', [
    'except' => ['edit', 'create']
]);

API Resource controller

Laravel 5.5 added another method for dealing with routes for resource controllers. API Resource Controller acts exactly like shown above, but does not register create and edit routes. It is meant to be used for ease of mapping routes used in RESTful APIs - where you typically do not have any kind of data located in create nor edit methods.

Route::apiResource('users', 'UsersController');

RESTful Resource Controller documentation

Implicit controller

An Implicit controller is more flexible. You get routed to your controller methods based on the HTTP request type and name. However, you don't have route names defined for you and it will catch all subfolders for the same route.

Route::controller('users', 'UserController');

Would lead you to set up the controller with a sort of RESTful naming scheme:

class UserController extends BaseController {

    public function getIndex()
    {
        // GET request to index
    }

    public function getShow($id)
    {
        // get request to 'users/show/{id}'
    }

    public function postStore()
    {
        // POST request to 'users/store'
    }

}

Implicit Controller documentation

It is good practice to use what you need, as per your preference. I personally don't like the Implicit controllers, because they can be messy, don't provide names and can be confusing when using php artisan routes. I typically use RESTful Resource controllers in combination with explicit routes.

Today date:

$( ".selector" ).datepicker( "setDate", new Date());
// Or on the init
$( ".selector" ).datepicker({ defaultDate: new Date() });

15 days from today:

$( ".selector" ).datepicker( "setDate", 15);
// Or on the init
$( ".selector" ).datepicker({ defaultDate: 15 });

jQuery ui docs

It seems you may be more comfortable with developing in PHP you let this hold you back from utilizing the full potential with web applications.

It is indeed possible to have PHP render partials and whole views, but I would not recommend it.

To fully utilize the possibilities of HTML and javascript to make a web application, that is, a web page that acts more like an application and relies heavily on client side rendering, you should consider letting the client maintain all responsibility of managing state and presentation. This will be easier to maintain, and will be more user friendly.

I would recommend you to get more comfortable thinking in a more API centric approach. Rather than having PHP output a pre-rendered view, and use angular for mere DOM manipulation, you should consider having the PHP backend output the data that should be acted upon RESTFully, and have Angular present it.

Using PHP to render the view:

/user/account

if($loggedIn)
{
    echo "<p>Logged in as ".$user."</p>";
}
else
{
    echo "Please log in.";
}

How the same problem can be solved with an API centric approach by outputting JSON like this:

api/auth/

{
  authorized:true,
  user: {
      username: 'Joe', 
      securityToken: 'secret'
  }
}

and in Angular you could do a get, and handle the response client side.

$http.post("http://example.com/api/auth", {})
.success(function(data) {
    $scope.isLoggedIn = data.authorized;
});

To blend both client side and server side the way you proposed may be fit for smaller projects where maintainance is not important and you are the single author, but I lean more towards the API centric way as this will be more correct separation of conserns and will be easier to maintain.

Try using date and time functions (MONTH(), YEAR(), DAY(), MySQL Manual)

This week:

SELECT * FROM jokes WHERE WEEKOFYEAR(date)=WEEKOFYEAR(NOW());

Last week:

SELECT * FROM jokes WHERE WEEKOFYEAR(date)=WEEKOFYEAR(NOW())-1;

I’ll try to answer the actual question of what a stack is.

In the Internet architecture (TCP/IP, OSI, etc.), protocols and software are often “stacked” on top of each other, as they depend on each other for support. For example, TCP provides reliable transmissions of data, on top of IP. The same goes for LAMP, your Apache server needs to run “on top of Linux”. Think of this “stack” as your favorite stack of pancakes, where each pancake is a different layer.

Yummy.
