Below is a simple way to convert dataframe column into numpy array.

df = pd.DataFrame(somedict) 
ytrain = df['label']
ytrain_numpy = np.array([x for x in ytrain['label']])

ytrain_numpy is a numpy array.

I tried with to.numpy() but it gave me the below error: TypeError: no supported conversion for types: (dtype('O'),) while doing Binary Relevance classfication using Linear SVC. to.numpy() was converting the dataFrame into numpy array but the inner element's data type was list because of which the above error was observed.

I had the following error while running the cell.

This may be due to not having ffmpeg in your system. Try the following command in your terminal.

sudo apt install ffmpeg

This works for me. I hope it will work out for you too.

I would change your service layer to:

public Task<BackOfficeResponse<List<Country>>> ReturnAllCountries()
{
    return Task.Run(() =>
    {
        return _service.Process<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
    }      
}

as you have it, you are still running your _service.Process call synchronously, and gaining very little or no benefit from awaiting it.

With this approach, you are wrapping the potentially slow call in a Task, starting it, and returning it to be awaited. Now you get the benefit of awaiting the Task.

You can get such a problem when you are two different commands on same connection - especially calling the second command in a loop. That is calling the second command for each record returned from the first command. If there are some 10,000 records returned by the first command, this issue will be more likely.

I used to avoid such a scenario by making it as a single command.. The first command returns all the required data and load it into a DataTable.

Note: MARS may be a solution - but it can be risky and many people dislike it.

System32 is where Windows historically placed all 32bit DLLs, and System was for the 16bit DLLs. When microsoft created the 64 bit OS, everyone I know of expected the files to reside under System64, but Microsoft decided it made more sense to put 64bit files under System32. The only reasoning I have been able to find, is that they wanted everything that was 32bit to work in a 64bit Windows w/o having to change anything in the programs -- just recompile, and it's done. The way they solved this, so that 32bit applications could still run, was to create a 32bit windows subsystem called Windows32 On Windows64. As such, the acronym SysWOW64 was created for the System directory of the 32bit subsystem. The Sys is short for System, and WOW64 is short for Windows32OnWindows64.
Since windows 16 is already segregated from Windows 32, there was no need for a Windows 16 On Windows 64 equivalence. Within the 32bit subsystem, when a program goes to use files from the system32 directory, they actually get the files from the SysWOW64 directory. But the process is flawed.

It's a horrible design. And in my experience, I had to do a lot more changes for writing 64bit applications, that simply changing the System32 directory to read System64 would have been a very small change, and one that pre-compiler directives are intended to handle.

To improve on the answer provided by @artofwarfare, here is what I consider a neater way to check for the message attribute and print it or print the Exception object as a fallback.

try:
    pass 
except Exception as e:
    print getattr(e, 'message', repr(e))

The call to repr is optional, but I find it necessary in some use cases.

Update #1:

Following the comment by @MadPhysicist, here's a proof of why the call to repr might be necessary. Try running the following code in your interpreter:

try:
    raise Exception 
except Exception as e:
    print(getattr(e, 'message', repr(e)))
    print(getattr(e, 'message', str(e)))

Update #2:

Here is a demo with specifics for Python 2.7 and 3.5: https://gist.github.com/takwas/3b7a6edddef783f2abddffda1439f533

Maybe there is an issue with your composer file. You could try:

• composer install installs the vendor packages according to composer.lock (or creates composer.lock if not present),

• composer update always regenerates composer.lock and installs the lastest versions of available packages based on composer.json

• composer dump-autoload won’t download a thing. It just regenerates the list of all classes that need to be included in the project (autoload_classmap.php). Ideal for when you have a new class inside your project. Ideally, you execute composer dump-autoload -o , for a faster load of your webpages. The only reason it is not default, is because it takes a bit longer to generate (but is only slightly noticeable)

source

import json
weather = urllib2.urlopen('url')
wjson = weather.read()
wjdata = json.loads(wjson)
print wjdata['data']['current_condition'][0]['temp_C']

What you get from the url is a json string. And your can't parse it with index directly. You should convert it to a dict by json.loads and then you can parse it with index.

Instead of using .read() to intermediately save it to memory and then read it to json, allow json to load it directly from the file:

wjdata = json.load(urllib2.urlopen('url'))

You can only do this to you own photos. Due to recent upgrades, Facebook has made this more difficult. To do this, go to the album page where the photo is that you want to link to. You should see thumbnail images of the photos in the album. Hold down the "Control" or "Command" key while clicking the photo that you wish to link to. A new browser tab will open with the picture you clicked. Under the picture there is a URL that you can send to others to share the photo. You might have to have the privacy settings for that album set so that anyone can see the photos in that album. If you don't the person who clicks the link may have to be signed in and also be your "friend."

Here is an example of one of my photos: http://www.facebook.com/photo.php?pid=43764341&l=0d8a526a64&id=25502298 -it's my cat.

Update:

The link below the photo no longer appears. Once you open the photo in a new tab you can right click the photo (Control+click for Mac users) and click "Copy Image URL" or similar and then share this link. Based on my tests the person who clicks the link doesn't need to use Facebook. The photo will load without the Facebook interface. Like this - http://a1.sphotos.ak.fbcdn.net/hphotos-ak-ash4/189088_867367406856_25502298_43764341_1304758_n.jpg

I needed this feature, but also wanted to make sure I did not return lines with a prefix before the ABB.log:

• ABB.log
• ABB.log.122
• ABB.log.123
• 123ABB.log

grep "\WABB.log$" -w a.tmp

You can simplify the 5 through 21 part:

=IF(E9>21,"Text1",IF(E9>4,"Text2","Text3"))

Here is how I solved the issue, might be useful to some:

Ajax modal doesn't seem to be available with boostrap 2.1.1

So I ended up coding it myself:

$('[data-toggle="modal"]').click(function(e) {
  e.preventDefault();
  var url = $(this).attr('href');
  //var modal_id = $(this).attr('data-target');
  $.get(url, function(data) {
      $(data).modal();
  });
});

Example of a link that calls a modal:

<a href="{{ path('ajax_get_messages', { 'superCategoryID': 6, 'sex': sex }) }}" data-toggle="modal">
    <img src="{{ asset('bundles/yopyourownpoet/images/messageCategories/BirthdaysAnniversaries.png') }}" alt="Birthdays" height="120" width="109"/>
</a>

I now send the whole modal markup through ajax.

As far as I know there is no mechanism for doing this in JUnit, however you could try subclassing Suite and overriding the run() method with a version that does provide hooks.

Jon Skeet is correct. Here is the Nul Device Driver page in the Windows Embedded documentation (I have no idea why it's not somewhere else...).

Create a function. Functions do specific things, classes are specific things.

Classes often have methods, which are functions that are associated with a particular class, and do things associated with the thing that the class is - but if all you want is to do something, a function is all you need.

Essentially, a class is a way of grouping functions (as methods) and data (as properties) into a logical unit revolving around a certain kind of thing. If you don't need that grouping, there's no need to make a class.

My answer: poor design choice. ;-)

This is an interesting debate focused on syntax impact. The core of the argument, in my view, is that a design decision led to sealed static classes. A focus on transparency of the static class's names appearing at the top level instead of hiding ('confusing') behind child names? One can image a language implementation that could access the base or the child directly, confusing.

A pseudo example, assuming static inheritance was defined in some way.

public static class MyStaticBase
{
    SomeType AttributeBase;
}

public static class MyStaticChild : MyStaticBase
{
    SomeType AttributeChild;
}

would lead to:

 // ...
 DoSomethingTo(MyStaticBase.AttributeBase);
// ...

which could (would?) impact the same storage as

// ...
DoSomethingTo(MyStaticChild.AttributeBase);
// ...

Very confusing!

But wait! How would the compiler deal with MyStaticBase and MyStaticChild having the same signature defined in both? If the child overrides than my above example would NOT change the same storage, maybe? This leads to even more confusion.

I believe there is a strong informational space justification for limited static inheritance. More on the limits shortly. This pseudocode shows the value:

public static class MyStaticBase<T>
{
   public static T Payload;
   public static void Load(StorageSpecs);
   public static void Save(StorageSpecs);
   public static SomeType AttributeBase
   public static SomeType MethodBase(){/*...*/};
}

Then you get:

public static class MyStaticChild : MyStaticBase<MyChildPlayloadType>
{
   public static SomeType AttributeChild;
   public static SomeType SomeChildMethod(){/*...*/};
   // No need to create the PlayLoad, Load(), and Save().
   // You, 'should' be prevented from creating them, more on this in a sec...
} 

Usage looks like:

// ...
MyStaticChild.Load(FileNamePath);
MyStaticChild.Save(FileNamePath);
doSomeThing(MyStaticChild.Payload.Attribute);
doSomething(MyStaticChild.AttributeBase);
doSomeThing(MyStaticChild.AttributeChild);
// ...

The person creating the static child does not need to think about the serialization process as long as they understand any limitations that might be placed on the platform's or environment's serialization engine.

Statics (singletons and other forms of 'globals') often come up around configuration storage. Static inheritance would allow this sort of responsibility allocation to be cleanly represented in the syntax to match a hierarchy of configurations. Though, as I showed, there is plenty of potential for massive ambiguity if basic static inheritance concepts are implemented.

I believe the right design choice would be to allow static inheritance with specific limitations:

1. No override of anything. The child cannot replace the base attributes, fields, or methods,... Overloading should be ok, as long as there is a difference in signature allowing the compiler to sort out child vs base.
2. Only allow generic static bases, you cannot inherit from a non-generic static base.

You could still change the same store via a generic reference MyStaticBase<ChildPayload>.SomeBaseField. But you would be discouraged since the generic type would have to be specified. While the child reference would be cleaner: MyStaticChild.SomeBaseField.

I am not a compiler writer so I am not sure if I am missing something about the difficulties of implementing these limitations in a compiler. That said, I am a strong believer that there is an informational space need for limited static inheritance and the basic answer is that you can't because of a poor (or over simple) design choice.

Difference between split and partition is split returns the list without delimiter and will split where ever it gets delimiter in string i.e.

x = 'http://test.com/lalala-134-431'

a,b,c = x.split(-)
print(a)
"http://test.com/lalala"
print(b)
"134"
print(c)
"431"

and partition will divide the string with only first delimiter and will only return 3 values in list

x = 'http://test.com/lalala-134-431'
a,b,c = x.partition('-')
print(a)
"http://test.com/lalala"
print(b)
"-"
print(c)
"134-431"

so as you want last value you can use rpartition it works in same way but it will find delimiter from end of string

x = 'http://test.com/lalala-134-431'
a,b,c = x.partition('-')
print(a)
"http://test.com/lalala-134"
print(b)
"-"
print(c)
"431"

Another way to do this is to add the new characters to the string as follows:

Dim str As String

str = ""

To append text to your string this way:

str = str & "and this is more text"

This can be done as below, just need to use JSON.parse, then you can traverse through it normally with indices.

#ideally not really needed, but in case if JSON.parse is not identifiable in your module  
require 'json'

#Assuming data from bitly api is stored in json_data here

json_data = '{
  "errorCode": 0,
  "errorMessage": "",
  "results":
  {
    "http://www.foo.com":
    {
       "hash": "e5TEd",
       "shortKeywordUrl": "",
       "shortUrl": "http://whateverurl",
       "userHash": "1a0p8G"
    }
  },
  "statusCode": "OK"
}'

final_data = JSON.parse(json_data)
puts final_data["results"]["http://www.foo.com"]["shortUrl"]

I guess the issue here is that you are updating INV_DISCOUNT and the INV_TOTAL uses the INV_DISCOUNT. so that is the issue here. You can use returning clause of update statement to use the new INV_DISCOUNT and use it to update INV_TOTAL.

this is a generic example let me know if this explains the point i mentioned

CREATE OR REPLACE PROCEDURE SingleRowUpdateReturn
IS
    empName VARCHAR2(50);
    empSalary NUMBER(7,2);      
BEGIN
    UPDATE emp
    SET sal = sal + 1000
    WHERE empno = 7499
    RETURNING ename, sal
    INTO empName, empSalary;

    DBMS_OUTPUT.put_line('Name of Employee: ' || empName);
    DBMS_OUTPUT.put_line('New Salary: ' || empSalary);
END;

Double quotes around the filename in the header is the standard per MDN web docs. Omitting the quotes creates multiple opportunities for problems arising from characters in the filename.

For anyone running a JDK on Ubuntu and want to upgrade to JDK11, I'd recommend installing via sdkman. SDKMAN is a tool for switching JVMs, removing and upgrading.

SDKMAN is a tool for managing parallel versions of multiple Software Development Kits on most Unix based systems. It provides a convenient Command Line Interface (CLI) and API for installing, switching, removing and listing Candidates.

Install SDKMAN

$ curl -s "https://get.sdkman.io" | bash
$ source "$HOME/.sdkman/bin/sdkman-init.sh"
$ sdk version

Install Java (11.0.3-zulu)

$ sdk install java

@Ryan Cavanaugh's answer is totally ok and still valid. Still it worth to add that as of Fall'16 when we can claim that ES6 is supported by the majority of platforms it almost always better to stick to Map whenever you need associate some data with some key.

When we write let a: { [s: string]: string; } we need to remember that after typescript compiled there's not such thing like type data, it's only used for compiling. And { [s: string]: string; } will compile to just {}.

That said, even if you'll write something like:

class TrickyKey  {}

let dict: {[key:TrickyKey]: string} = {}

This just won't compile (even for target es6, you'll get error TS1023: An index signature parameter type must be 'string' or 'number'.

So practically you are limited with string or number as potential key so there's not that much of a sense of enforcing type check here, especially keeping in mind that when js tries to access key by number it converts it to string.

So it is quite safe to assume that best practice is to use Map even if keys are string, so I'd stick with:

let staff: Map<string, string> = new Map();

Put the "hibernate-entitymanager.jar" in the classpath of application.
For newer versions, you should use "hibernate-core.jar" instead of the deprecated hibernate-entitymanager

If you are running through some IDE, like Eclipse: Project Properties -> Java Build Path -> Libraries.

Otherwise put it in the /lib of your application.

If the scenario is appending a new row dynamically, you can use this:

var row = $(".myRow").last().clone();
$(".myRow").last().after(row);

.myrow is the classname of the <tr>. It makes a copy of the last row and inserts that as a new last row. This also works in IE7, while the [0].outerHTML method does not allow assignments in ie7

Use jquery change event

Description: Bind an event handler to the "change" JavaScript event, or trigger that event on an element.

An example

$("input[type='text']").change( function() {
  // your code
});

The advantage that .change has over .keypress , .focus , .blur is that .change event will fire only when input has changed

So many answers and still everybody forgot about the strangely named, oddly behaved, and yet still handy dict.setdefault()

This

value = my_dict.setdefault(key, default)

basically just does this:

try:
    value = my_dict[key]
except KeyError: # key not found
    value = my_dict[key] = default

e.g.

>>> mydict = {'a':1, 'b':2, 'c':3}
>>> mydict.setdefault('d', 4)
4 # returns new value at mydict['d']
>>> print(mydict)
{'a':1, 'b':2, 'c':3, 'd':4} # a new key/value pair was indeed added
# but see what happens when trying it on an existing key...
>>> mydict.setdefault('a', 111)
1 # old value was returned
>>> print(mydict)
{'a':1, 'b':2, 'c':3, 'd':4} # existing key was ignored

In fact the "[" square opening bracket is just an internal shell alias for the test command.

So you can say:

test -f "/bin/bash" && echo "This system has a bash shell"

or

[ -f "/bin/bash" ] && echo "This system has a bash shell"

... they are equivalent in either sh or bash. Note the requirement to have a closing "]" bracket on the "[" command but other than that "[" is the same as "test". "man test" is a good thing to read.

You can use java System.properties, for using them from eclipse you could:

1. Add -Dlabel="label_value" in the VM arguments of the test Run Configuration like this:

2. Then run the test:

   import org.junit.Test;
   import static org.junit.Assert.assertEquals;
   
   public class Main {
       @Test
       public void test(){
           System.out.println(System.getProperty("label"));
           assertEquals("label_value", System.getProperty("label"));
       }
   }
   

3. Finally it should pass the test and output this in the console:

   label_value
   

I think groupby should work.

df.groupby(['A', 'B']).max()['C']

If you need a dataframe back you can chain the reset index call.

df.groupby(['A', 'B']).max()['C'].reset_index()

Note: According to JDN96, the answer below may cause a memory leak by repeatedly destroying and recreating frames. However, I have not tested to verify this myself.

One way to switch frames in tkinter is to destroy the old frame then replace it with your new frame.

I have modified Bryan Oakley's answer to destroy the old frame before replacing it. As an added bonus, this eliminates the need for a container object and allows you to use any generic Frame class.

# Multi-frame tkinter application v2.3
import tkinter as tk

class SampleApp(tk.Tk):
    def __init__(self):
        tk.Tk.__init__(self)

        self.switch_frame(StartPage)

    def switch_frame(self, frame_class):
        """Destroys current frame and replaces it with a new one."""
        new_frame = frame_class(self)
        if self._frame is not None:
            self._frame.destroy()
        self._frame = new_frame
        self._frame.pack()

class StartPage(tk.Frame):
    def __init__(self, master):
        tk.Frame.__init__(self, master)
        tk.Label(self, text="This is the start page").pack(side="top", fill="x", pady=10)
        tk.Button(self, text="Open page one",
                  command=lambda: master.switch_frame(PageOne)).pack()
        tk.Button(self, text="Open page two",
                  command=lambda: master.switch_frame(PageTwo)).pack()

class PageOne(tk.Frame):
    def __init__(self, master):
        tk.Frame.__init__(self, master)
        tk.Label(self, text="This is page one").pack(side="top", fill="x", pady=10)

                  command=lambda: master.switch_frame(StartPage)).pack()

class PageTwo(tk.Frame):
    def __init__(self, master):
        tk.Frame.__init__(self, master)
        tk.Label(self, text="This is page two").pack(side="top", fill="x", pady=10)
        tk.Button(self, text="Return to start page",

if __name__ == "__main__":
    app = SampleApp()
    app.mainloop()

Explanation

switch_frame() works by accepting any Class object that implements Frame. The function then creates a new frame to replace the old one.

• Deletes old _frame if it exists, then replaces it with the new frame.
• Other frames added with .pack(), such as menubars, will be unaffected.
• Can be used with any class that implements tkinter.Frame.
• Window automatically resizes to fit new content

Version History

v2.3

- Pack buttons and labels as they are initialized

v2.2

- Initialize `_frame` as `None`.
- Check if `_frame` is `None` before calling `.destroy()`.

v2.1.1

- Remove type-hinting for backwards compatibility with Python 3.4.

v2.1

- Add type-hinting for `frame_class`.

v2.0

- Remove extraneous `container` frame.
    - Application now works with any generic `tkinter.frame` instance.
- Remove `controller` argument from frame classes.
    - Frame switching is now done with `master.switch_frame()`.

v1.6

- Check if frame attribute exists before destroying it.
- Use `switch_frame()` to set first frame.

v1.5

  - Revert 'Initialize new `_frame` after old `_frame` is destroyed'.
      - Initializing the frame before calling `.destroy()` results
        in a smoother visual transition.

v1.4

- Pack frames in `switch_frame()`.
- Initialize new `_frame` after old `_frame` is destroyed.
    - Remove `new_frame` variable.

v1.3

- Rename `parent` to `master` for consistency with base `Frame` class.

v1.2

- Remove `main()` function.

v1.1

- Rename `frame` to `_frame`.
    - Naming implies variable should be private.
- Create new frame before destroying old frame.

v1.0

- Initial version.

As it stands, there is no 'autocomplete off' attribute in CSS. However, html has an easy code for this:

<input type="text" id="foo" value="bar" autocomplete="off" />

If you're looking for a site-wide effector, an easy one would be to simply have a js function to run through all 'input' s and add this tag, or look for the corresponding css class / id.

The autocomplete attribute works fine in Chrome and Firefox (!), but see also Is there a W3C valid way to disable autocomplete in a HTML form?

You just need:

$("selector").get(0).scrollTo(0, 0)

If you call it the way you had it...

$('.leadtoscore').click(add_event('shot'));

...you would need to have add_event() return a function, like...

function add_event(param) {
    return function() {
                // your code that does something with param
                alert( param );
           };
}

The function is returned and used as the argument for .click().

I had this issue when I used npm link to install my local library, which I've built using cra. I found the answer here. Which literally says:

This problem can also come up when you use npm link or an equivalent. In that case, your bundler might “see” two Reacts — one in application folder and one in your library folder. Assuming 'myapp' and 'mylib' are sibling folders, one possible fix is to run 'npm link ../myapp/node_modules/react' from 'mylib'. This should make the library use the application’s React copy.

Thus, running the command: npm link ../../libraries/core/decipher/node_modules/react from my project folder has fixed the issue.

This solution will only add the border, the body of the LinearLayout will be transparent.

First, Create this border drawable in the drawable folder, border.xml

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android= "http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <stroke android:width="2dp" android:color="#ec0606"/>
    <corners android:radius="10dp"/>
</shape>

Then, in your LinearLayout View, add the border.xml as the background like this

<LinearLayout 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="@drawable/border">

In Angular 2 this is how we can set the default value for radio button:

HTML:

<label class="form-check-label">
          <input type="radio" class="form-check-input" name="gender" 
          [(ngModel)]="gender" id="optionsRadios1" value="male">
          Male
</label>

In the Component Class set the value of 'gender' variable equal to the value of radio button:

gender = 'male';

your question is basically O/RM's vs hand writing SQL

Using an ORM or plain SQL?

Take a look at some of the other O/RM solutions out there, L2S isn't the only one (NHibernate, ActiveRecord)

http://en.wikipedia.org/wiki/List_of_object-relational_mapping_software

to address the specific questions:

1. Depends on the quality of the O/RM solution, L2S is pretty good at generating SQL
2. This is normally much faster using an O/RM once you grok the process
3. Code is also usually much neater and more maintainable
4. Straight SQL will of course get you more flexibility, but most O/RM's can do all but the most complicated queries
5. Overall I would suggest going with an O/RM, the flexibility loss is negligable

Try new_list = a[0:2] + [a[4]] + a[6:].

Or more generally, something like this:

from itertools import chain
new_list = list(chain(a[0:2], [a[4]], a[6:]))

This works with other sequences as well, and is likely to be faster.

Or you could do this:

def chain_elements_or_slices(*elements_or_slices):
    new_list = []
    for i in elements_or_slices:
        if isinstance(i, list):
            new_list.extend(i)
        else:
            new_list.append(i)
    return new_list

new_list = chain_elements_or_slices(a[0:2], a[4], a[6:])

But beware, this would lead to problems if some of the elements in your list were themselves lists. To solve this, either use one of the previous solutions, or replace a[4] with a[4:5] (or more generally a[n] with a[n:n+1]).

You need to first check if it's a number. If so you can use the Math.Round method. If the result and the original value are equal then it's an integer.

I found a solution for my problem while writing my question !

Going into my remote session i tried two key combinations, and it solved the problem on my Desktop : Alt+Enter and Ctrl+Enter (i don't know which one solved the problem though)

I tried to reproduce the problem, but i couldn't... but i'm almost sure it's one of the key combinations described in the question above (since i experienced this problem several times)

So it seems the problem comes from the use of RDP (windows7 and 8)

Update 2017: Problem occurs on Windows 10 aswell.

I know this is old but this answer came up in search results. For the next guy - the proposed and accepted answer works, however the code initially submitted in the question is lower-level than it needs to be. Nobody got time for that.

//one-line post request/response...
response, err := http.PostForm(APIURL, url.Values{
    "ln": {c.ln},
    "ip": {c.ip},
    "ua": {c.ua}})

//okay, moving on...
if err != nil {
  //handle postform error
}

defer response.Body.Close()
body, err := ioutil.ReadAll(response.Body)

if err != nil {
  //handle read response error
}

fmt.Printf("%s\n", string(body))

I have implemented a solution for:

• Dynamic fragment replacement inside the tab
• Maintenance of the history per tab
• Working with orientation changes

The tricks to achieve this are the following:

• Use the notifyDataSetChanged() method to apply the fragment replacement
• Use the fragment manager only for back stage and no for fragament replacement
• Maintain the history using the memento pattern (stack)

The adapter code is the following:

public class TabsAdapter extends FragmentStatePagerAdapter implements ActionBar.TabListener, ViewPager.OnPageChangeListener {

/** The sherlock fragment activity. */
private final SherlockFragmentActivity mActivity;

/** The action bar. */
private final ActionBar mActionBar;

/** The pager. */
private final ViewPager mPager;

/** The tabs. */
private List<TabInfo> mTabs = new LinkedList<TabInfo>();

/** The total number of tabs. */
private int TOTAL_TABS;

private Map<Integer, Stack<TabInfo>> history = new HashMap<Integer, Stack<TabInfo>>();

/**
 * Creates a new instance.
 *
 * @param activity the activity
 * @param pager    the pager
 */
public TabsAdapter(SherlockFragmentActivity activity, ViewPager pager) {
    super(activity.getSupportFragmentManager());
    activity.getSupportFragmentManager();
    this.mActivity = activity;
    this.mActionBar = activity.getSupportActionBar();
    this.mPager = pager;
    mActionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
}

    final TabInfo tabInfo = new TabInfo(fragmentClass, args);
    final ActionBar.Tab tab = mActionBar.newTab();
    tab.setTabListener(this);
    tab.setTag(tabInfo);
    tab.setIcon(image);

    mTabs.add(tabInfo);
    mActionBar.addTab(tab);

    notifyDataSetChanged();
}

The very first time you add all tabs, we need to call the method createHistory(), to create the initial history

public void createHistory() {
    int position = 0;
    TOTAL_TABS = mTabs.size();
    for (TabInfo mTab : mTabs) {
        if (history.get(position) == null) {
            history.put(position, new Stack<TabInfo>());
        }
        history.get(position).push(new TabInfo(mTab.fragmentClass, mTab.args));
        position++;
    }
}

Every time you want to replace a fragment to a specific tab you call: replace(final int position, final Class fragmentClass, final Bundle args)

/* Save the fragment to the history. */
    mActivity.getSupportFragmentManager().beginTransaction().addToBackStack(null).commit();

    /* Update the tabs. */
    updateTabs(new TabInfo(fragmentClass, args), position);

    /* Updates the history. */
    history.get(position).push(new TabInfo(mTabs.get(position).fragmentClass, mTabs.get(position).args));

    notifyDataSetChanged();

On back pressed you need to call the back() method:

public void back() {
    int position = mActionBar.getSelectedTab().getPosition();
    if (!historyIsEmpty(position)) {
        /* In case there is not any other item in the history, then finalize the activity. */
        if (isLastItemInHistory(position)) {
            mActivity.finish();
        }
        final TabInfo currentTabInfo = getPrevious(position);
        mTabs.clear();
        for (int i = 0; i < TOTAL_TABS; i++) {
            if (i == position) {
                mTabs.add(new TabInfo(currentTabInfo.fragmentClass, currentTabInfo.args));
            } else {
                TabInfo otherTabInfo = history.get(i).peek();
                mTabs.add(new TabInfo(otherTabInfo.fragmentClass, otherTabInfo.args));
            }
        }
    }
    mActionBar.selectTab(mActionBar.getTabAt(position));
    notifyDataSetChanged();
}

The solution works with sherlock action bar and with swipe gesture.

Use PHP's empty() function. The following things are considered to be empty

"" (an empty string)
0 (0 as an integer)
0.0 (0 as a float)
"0" (0 as a string)
NULL
FALSE
array() (an empty array)
$var; (a variable declared, but without a value)

For more details check empty function

I modified some thing that were poping up error for me and end up with this which worked great to extract the data as I needed:

Sub get_data_web()

Dim appIE As Object
Set appIE = CreateObject("internetexplorer.application")

With appIE
    .navigate "https://finance.yahoo.com/quote/NQ%3DF/futures?p=NQ%3DF"
    .Visible = True
End With

Do While appIE.Busy
    DoEvents
Loop

Set allRowofData = appIE.document.getElementsByClassName("Ta(end) BdT Bdc($c-fuji-grey-c) H(36px)")

Dim i As Long
Dim myValue As String

Count = 1

    For Each itm In allRowofData

        For i = 0 To 4

        myValue = itm.Cells(i).innerText
        ActiveSheet.Cells(Count, i + 1).Value = myValue

        Next

        Count = Count + 1

    Next

appIE.Quit
Set appIE = Nothing


End Sub

I noticed that there is no selected feature in datalist. It only gives you choice but can't have a default option. You can't show the selected option on the next page either.

you can see the solution on http://jsfiddle.net/CBQCA/1/

OR

<table style="height:100%;width:100%; position: absolute; top: 0; bottom: 0; left: 0; right: 0;border:1px solid">
     <tr style="height: 25%;">
        <td>Region</td>
    </tr>
    <tr style="height: 75%;">
        <td>100.00%</td>
    </tr>
</table>?

I removed the font size, to show that columns are expanded. I added border:1px solid just to make sure table is expanded. you can remove it.

From ggplot2 2.0.0 you can use the margin = argument of element_text() to change the distance between the axis title and the numbers. Set the values of the margin on top, right, bottom, and left side of the element.

ggplot(mpg, aes(cty, hwy)) + geom_point()+
  theme(axis.title.y = element_text(margin = margin(t = 0, r = 20, b = 0, l = 0)))

margin can also be used for other element_text elements (see ?theme), such as axis.text.x, axis.text.y and title.

addition

in order to set the margin for axis titles when the axis has a different position (e.g., with scale_x_...(position = "top"), you'll need a different theme setting - e.g. axis.title.x.top. See https://github.com/tidyverse/ggplot2/issues/4343.

This is often achieved by throwing an error from the current context; then analyzing error object for properties like lineNumber and fileName (which some browsers have)

function getErrorObject(){
  try { throw Error('') } catch(err) { return err; }
}

var err = getErrorObject();

err.fileName;
err.lineNumber; // or `err.line` in WebKit

Don't forget that callee.caller property is deprecated (and was never really in ECMA 3rd ed. in the first place).

Also remember that function decompilation is specified to be implementation dependent and so might yield quite unexpected results. I wrote about it here and here.

Also a bit late, but maybe helpful for some. I am using a combination of ConfigParser and JSON:

[Foo]
fibs: [1,1,2,3,5,8,13]

just read it with:

>>> json.loads(config.get("Foo","fibs"))
[1, 1, 2, 3, 5, 8, 13]

You can even break lines if your list is long (thanks @peter-smit):

[Bar]
files_to_check = [
     "/path/to/file1",
     "/path/to/file2",
     "/path/to/another file with space in the name"
     ]

Of course i could just use JSON, but i find config files much more readable, and the [DEFAULT] Section very handy.

Just another cause: If you open Charles, you could also met this problem, in this case just quit Charles.

Use Query.setParameterList(), Javadoc here.

There are four variants to pick from.

And of course you can return lambdas as well from a decorator function:

def makebold(f): 
    return lambda: "<b>" + f() + "</b>"
def makeitalic(f): 
    return lambda: "<i>" + f() + "</i>"

@makebold
@makeitalic
def say():
    return "Hello"

print say()

$.get does not give you the opportunity to set an error handler. You will need to use the low-level $.ajax function instead:

$.ajax({
    url: 'http://example.com/page/2/',
    type: 'GET',
    success: function(data){ 
        $(data).find('#reviews .card').appendTo('#reviews');
    },
    error: function(data) {
        alert('woops!'); //or whatever
    }
});

Edit March '10

Note that with the new jqXHR object in jQuery 1.5, you can set an error handler after calling $.get:

$.get('http://example.com/page/2/', function(data){ 
    $(data).find('#reviews .card').appendTo('#reviews');
}).fail(function() {
    alert('woops'); // or whatever
});

I'd like to centralize the creation of the error response in this way:

app.get('/test', function(req, res){
  throw {status: 500, message: 'detailed message'};
});

app.use(function (err, req, res, next) {
  res.status(err.status || 500).json({status: err.status, message: err.message})
});

So I have always the same error output format.

PS: of course you could create an object to extend the standard error like this:

const AppError = require('./lib/app-error');
app.get('/test', function(req, res){
  throw new AppError('Detail Message', 500)
});

'use strict';

module.exports = function AppError(message, httpStatus) {
  Error.captureStackTrace(this, this.constructor);
  this.name = this.constructor.name;
  this.message = message;
  this.status = httpStatus;
};

require('util').inherits(module.exports, Error);

I managed to get this working in Chrome and Firefox too by appending a link to the to document.

var link = document.createElement('a');
link.href = 'images.jpg';
link.download = 'Download.jpg';
document.body.appendChild(link);
link.click();
document.body.removeChild(link);

Simply create a new external tool configuration (from Eclipse Run -> External Tools)

for example - To open Cygwin terminal on the current resource directory:

Location:

C:\cygwin\bin\mintty.exe

Working Directory:

${container_loc}

Arguments:

-i /Cygwin-Terminal.ico  
-"cygpath -p '${container_loc}' | xargs cd"

Different IIS web servers can process different amounts of data in the 'header', according to this (now deleted) article; http://classicasp.aspfaq.com/forms/what-is-the-limit-on-form/post-parameters.html;

Note that there is no limit on the number of FORM elements you can pass via POST, but only on the aggregate size of all name/value pairs. While GET is limited to as low as 1024 characters, POST data is limited to 2 MB on IIS 4.0, and 128 KB on IIS 5.0. Each name/value is limited to 1024 characters, as imposed by the SGML spec. Of course this does not apply to files uploaded using enctype='multipart/form-data' ... I have had no problems uploading files in the 90 - 100 MB range using IIS 5.0, aside from having to increase the server.scriptTimeout value as well as my patience!

If you want to do this and control the server from which the base page or content is being served, you can use Cross Origin Resource Sharing (http://www.w3.org/TR/access-control/) to allow client-side JavaScript to load data into a <div> via XMLHttpRequest():

// I safely ignore IE 6 and 5 (!) users
// because I do not wish to proliferate
// broken software that will hurt other
// users of the internet, which is what
// you're doing when you write anything
// for old version of IE (5/6)
xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
  if(xhr.readyState == 4 && xhr.status == 200) {
    document.getElementById('displayDiv').innerHTML = xhr.responseText;
  }
};
xhr.open('GET', 'http://api.google.com/thing?request=data', true);
xhr.send();

Now for the lynchpin of this whole operation, you need to write code for your server that will give clients the Access-Control-Allow-Origin header, specifying which domains you want the client-side code to be able to access via XMLHttpRequest(). The following is an example of PHP code you can include at the top of your page in order to send these headers to clients:

<?php
  header('Access-Control-Allow-Origin: http://api.google.com');
  header('Access-Control-Allow-Origin: http://some.example.com');
?>

I did not manage to find a way to do it directly.

Instead I imported the bak file into SQL Server 2008 Express, and then used MySQL Migration Toolkit.

Worked like a charm!

You are using improper syntax. If you read the docs mysqli_query() you will find that it needs two parameter.

mixed mysqli_query ( mysqli $link , string $query [, int $resultmode = MYSQLI_STORE_RESULT ] )

mysql $link generally means, the resource object of the established mysqli connection to query the database.

So there are two ways of solving this problem

mysqli_query();

$myConnection= mysqli_connect("$db_host","$db_username","$db_pass", "mrmagicadam") or die ("could not connect to mysql"); 
$sqlCommand="SELECT id, linklabel FROM pages ORDER BY pageorder ASC";
$query=mysqli_query($myConnection, $sqlCommand) or die(mysqli_error($myConnection));

Or, Using mysql_query() (This is now obselete)

$myConnection= mysql_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql");
mysql_select_db("mrmagicadam") or die ("no database");        
$sqlCommand="SELECT id, linklabel FROM pages ORDER BY pageorder ASC";
$query=mysql_query($sqlCommand) or die(mysql_error());

As pointed out in the comments, be aware of using die to just get the error. It might inadvertently give the viewer some sensitive information .

There are different types of shells. The SSH command execution shell is a non-interactive shell, whereas your normal shell is either a login shell or an interactive shell. Description follows, from man bash:

       A  login  shell  is  one whose first character of argument
       zero is a -, or one started with the --login option.

       An interactive shell is  one  started  without  non-option
       arguments  and  without the -c option whose standard input
       and error are both connected to terminals  (as  determined
       by  isatty(3)), or one started with the -i option.  PS1 is
       set and $- includes i if bash is interactive,  allowing  a
       shell script or a startup file to test this state.

       The  following  paragraphs  describe how bash executes its
       startup files.  If any of the files exist  but  cannot  be
       read,  bash reports an error.  Tildes are expanded in file
       names as described below  under  Tilde  Expansion  in  the
       EXPANSION section.

       When  bash is invoked as an interactive login shell, or as
       a non-interactive shell with the --login option, it  first
       reads and executes commands from the file /etc/profile, if
       that file exists.  After reading that file, it  looks  for
       ~/.bash_profile,  ~/.bash_login,  and  ~/.profile, in that
       order, and reads and executes commands from the first  one
       that  exists  and is readable.  The --noprofile option may
       be used when the shell is started to inhibit  this  behav­
       ior.

       When a login shell exits, bash reads and executes commands
       from the file ~/.bash_logout, if it exists.

       When an interactive shell that is not  a  login  shell  is
       started,  bash reads and executes commands from ~/.bashrc,
       if that file exists.  This may be inhibited by  using  the
       --norc  option.   The --rcfile file option will force bash
       to  read  and  execute  commands  from  file  instead   of
       ~/.bashrc.

       When  bash  is  started  non-interactively, to run a shell
       script, for example, it looks for the variable BASH_ENV in
       the  environment,  expands  its value if it appears there,
       and uses the expanded value as the name of a file to  read
       and  execute.   Bash  behaves  as if the following command
       were executed:
              if [ -n "$BASH_ENV" ]; then . "$BASH_ENV"; fi
       but the value of the PATH variable is not used  to  search
       for the file name.

The other solutions that use the GLOBAL keyword are a nightmare to maintain/readability (+namespace pollution and bugs) when the project gets bigger. I've seen this mistake many times and had the hassle of fixing it.

Use a JavaScript file and then use module exports.

Example:

File globals.js

var Globals = {
    'domain':'www.MrGlobal.com';
}

module.exports = Globals;

Then if you want to use these, use require.

var globals = require('globals'); // << globals.js path
globals.domain // << Domain.

Web API works very nicely if you accept the fact that you are using HTTP. It's when you start trying to pretend that you are sending objects over the wire that it starts to get messy.

 public class TextController : ApiController
    {
        public HttpResponseMessage Post(HttpRequestMessage request) {

            var someText = request.Content.ReadAsStringAsync().Result;
            return new HttpResponseMessage() {Content = new StringContent(someText)};

        }

    }

This controller will handle a HTTP request, read a string out of the payload and return that string back.

You can use HttpClient to call it by passing an instance of StringContent. StringContent will be default use text/plain as the media type. Which is exactly what you are trying to pass.

    [Fact]
    public void PostAString()
    {

        var client = new HttpClient();

        var content = new StringContent("Some text");
        var response = client.PostAsync("http://oak:9999/api/text", content).Result;

        Assert.Equal("Some text",response.Content.ReadAsStringAsync().Result);

    }

In case that you have Ubuntu in your machine, the following steps will help you:

1. Check first in your php testing file if you have soap (client / server)or not by using phpinfo(); and check results in the browser. In case that you have it, it will seems like the following image ( If not go to step 2 ):

2. Open your terminal and paste: sudo apt-get install php-soap.

3. Restart your apache2 server in terminal : service apache2 restart.

4. To check use your php test file again to be seems like mine in step 1.

In the first case, the data are passed to the script via GET, in the second via POST.

I don't think there are limits to the data size, but the completition of the remote call will of course take longer with great amount of data.

What Anthony says is absolutely correct, but I'd like to add that your experience will likely show a lot better performance and efficiency (due not to fpm-vs-fcgi but more to the implementation of your httpd).

For example, I had a quad-core machine running lighttpd + fcgi humming along nicely. I upgraded to a 16-core machine to cope with growth, and two things exploded: RAM usage, and segfaults. I found myself restarting lighttpd every 30 minutes to keep the website up.

I switched to php-fpm and nginx, and RAM usage dropped from >20GB to 2GB. Segfaults disappeared as well. After doing some research, I learned that lighttpd and fcgi don't get along well on multi-core machines under load, and also have memory leak issues in certain instances.

Is this due to php-fpm being better than fcgi? Not entirely, but how you hook into php-fpm seems to be a whole heckuva lot more efficient than how you serve via fcgi.

While saying "the compiler can reserve", why rely on it? And what about automatic detection of move semantics? And what about all that repeating of the container name with the begins and ends?

Wouldn't you want something, you know, simpler?

Note that the above does not compile in clang thanks to the EnableFunctionIf<>... technique. In clang this workaround works.

Confirm in API documentation http://api.jquery.com/jQuery.each/ say:

We can break the $.each() loop at a particular iteration by making the callback function return false. Returning non-false is the same as a continue statement in a for loop; it will skip immediately to the next iteration.

and this is my example http://jsfiddle.net/r6jqP/

(function($){
    $('#go').on('click',function(){
        var i=0,
            all=0;
        $('li').each(function(){
             all++;
             if($('#mytext').val()=='continue')return true;
             i++;
             if($('#mytext').val()==$(this).html()){
                 return false;
             }
        });
        alert('Iterazione : '+i+' to '+all);
    });

If it is going to be a web based application, you can also use the ServletContextListener interface.

public class SLF4JBridgeListener implements ServletContextListener {

   @Autowired 
   ThreadPoolTaskExecutor executor;

   @Autowired 
   ThreadPoolTaskScheduler scheduler;

    @Override
    public void contextInitialized(ServletContextEvent sce) {

    }

    @Override
    public void contextDestroyed(ServletContextEvent sce) {
         scheduler.shutdown();
         executor.shutdown();     

    }

}

 1.   NSTemporaryDirectory() gives this:

    /Users/spokaneDude/Library/Developer/CoreSimulator/Devices/1EE69744-255A-45CD-88F1-63FEAD117B32/data/Containers/Data/Application/199B1ACA-A80B-44BD-8E5E-DDF3DCF0D8D9/tmp

 2. remove "/tmp" replacing it with "/Library/Application Support/<app name>/"  --> is where the .sqlite files reside

In addition to @Cinn's answer, you can define a class like this

class MyAppBar extends AppBar with PreferredSizeWidget {
  @override
  get preferredSize => Size.fromHeight(50);

  MyAppBar({Key key, Widget title}) : super(
    key: key,
    title: title,
    // maybe other AppBar properties
  );
}

or this way

class MyAppBar extends PreferredSize {
  MyAppBar({Key key, Widget title}) : super(
    key: key,
    preferredSize: Size.fromHeight(50),
    child: AppBar(
      title: title,
      // maybe other AppBar properties
    ),
  );
}

and then use it instead of standard one

As of Python 3.4, subtests have been introduced to unittest for this purpose. See the documentation for details. TestCase.subTest is a context manager which allows one to isolate asserts in a test so that a failure will be reported with parameter information, but it does not stop the test execution. Here's the example from the documentation:

class NumbersTest(unittest.TestCase):

def test_even(self):
    """
    Test that numbers between 0 and 5 are all even.
    """
    for i in range(0, 6):
        with self.subTest(i=i):
            self.assertEqual(i % 2, 0)

The output of a test run would be:

======================================================================
FAIL: test_even (__main__.NumbersTest) (i=1)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "subtests.py", line 32, in test_even
    self.assertEqual(i % 2, 0)
AssertionError: 1 != 0

======================================================================
FAIL: test_even (__main__.NumbersTest) (i=3)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "subtests.py", line 32, in test_even
    self.assertEqual(i % 2, 0)
AssertionError: 1 != 0

======================================================================
FAIL: test_even (__main__.NumbersTest) (i=5)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "subtests.py", line 32, in test_even
    self.assertEqual(i % 2, 0)
AssertionError: 1 != 0

This is also part of unittest2, so it is available for earlier versions of Python.

Using figure environment and .set_clim()

Could be easier and safer this alternative if you have multiple plots:

import matplotlib as m
import matplotlib.pyplot as plt
import numpy as np

cdict = {
  'red'  :  ( (0.0, 0.25, .25), (0.02, .59, .59), (1., 1., 1.)),
  'green':  ( (0.0, 0.0, 0.0), (0.02, .45, .45), (1., .97, .97)),
  'blue' :  ( (0.0, 1.0, 1.0), (0.02, .75, .75), (1., 0.45, 0.45))
}

cm = m.colors.LinearSegmentedColormap('my_colormap', cdict, 1024)

x = np.arange(0, 10, .1)
y = np.arange(0, 10, .1)
X, Y = np.meshgrid(x,y)

data = 2*( np.sin(X) + np.sin(3*Y) )
data1 = np.clip(data,0,6)
data2 = np.clip(data,-6,0)
vmin = np.min(np.array([data,data1,data2]))
vmax = np.max(np.array([data,data1,data2]))

fig = plt.figure()
ax = fig.add_subplot(131)
mesh = ax.pcolormesh(data, cmap = cm)
mesh.set_clim(vmin,vmax)
ax1 = fig.add_subplot(132)
mesh1 = ax1.pcolormesh(data1, cmap = cm)
mesh1.set_clim(vmin,vmax)
ax2 = fig.add_subplot(133)
mesh2 = ax2.pcolormesh(data2, cmap = cm)
mesh2.set_clim(vmin,vmax)
# Visualizing colorbar part -start
fig.colorbar(mesh,ax=ax)
fig.colorbar(mesh1,ax=ax1)
fig.colorbar(mesh2,ax=ax2)
fig.tight_layout()
# Visualizing colorbar part -end

plt.show()

A single colorbar

The best alternative is then to use a single color bar for the entire plot. There are different ways to do that, this tutorial is very useful for understanding the best option. I prefer this solution that you can simply copy and paste instead of the previous visualizing colorbar part of the code.

fig.subplots_adjust(bottom=0.1, top=0.9, left=0.1, right=0.8,
                    wspace=0.4, hspace=0.1)
cb_ax = fig.add_axes([0.83, 0.1, 0.02, 0.8])
cbar = fig.colorbar(mesh, cax=cb_ax)

P.S.

I would suggest using pcolormesh instead of pcolor because it is faster (more infos here ).

Your problem is that you have to change:

printf("%"); 

to

printf("%%");

Or you could use ASCII code and write:

printf("%c", 37);

:)

In Swift 2:

extension NSMutableURLRequest {
    func setAuthorizationHeader(username username: String, password: String) -> Bool {
        guard let data = "\(username):\(password)".dataUsingEncoding(NSUTF8StringEncoding) else { return false }

        let base64 = data.base64EncodedStringWithOptions([])
        setValue("Basic \(base64)", forHTTPHeaderField: "Authorization")
        return true
    }
}

This might be a little off the question, but for those interested in the randomness of the generated string, my answer would be:

import os
import string

def _pwd_gen(size=16):
    chars = string.letters
    chars_len = len(chars)
    return str().join(chars[int(ord(c) / 256. * chars_len)] for c in os.urandom(size))

See these answers and random.py's source for more insight.

Localstorage is designed to be accessible by javascript, so it doesn't provide any XSS protection. As mentioned in other answers, there is a bunch of possible ways to do an XSS attack, from which localstorage is not protected by default.

However, cookies have security flags which protect from XSS and CSRF attacks. HttpOnly flag prevents client side javascript from accessing the cookie, Secure flag only allows the browser to transfer the cookie through ssl, and SameSite flag ensures that the cookie is sent only to the origin. Although I just checked and SameSite is currently supported only in Opera and Chrome, so to protect from CSRF it's better to use other strategies. For example, sending an encrypted token in another cookie with some public user data.

So cookies are a more secure choice for storing authentication data.

for each project in your solution make sure that

Properties > Config. Properties > General > Platform Toolset

is one for all of them, v100 for visual studio 2010, v110 for visual studio 2012

you also may be working on v100 from visual studio 2012

For a one-page web application where I add scrollable sections dynamically, I trigger OSX's scrollbars by programmatically scrolling one pixel down and back up:

// Plain JS:
var el = document.getElementById('scrollable-section');
el.scrollTop = 1;
el.scrollTop = 0;

// jQuery:
$('#scrollable-section').scrollTop(1).scrollTop(0);

This triggers the visual cue fading in and out.

Ok, I've been working on this for a few hours, and I've developed what I believe to be the most pythonic solution yet. The following code snippets are python3 but shouldn't be too horribly painful to backport if you need.

The first thing we're gonna do is start with a mixin that makes your db models act kinda like dicts:

from sqlalchemy.inspection import inspect

class ModelMixin:
    """Provide dict-like interface to db.Model subclasses."""

    def __getitem__(self, key):
        """Expose object attributes like dict values."""
        return getattr(self, key)

    def keys(self):
        """Identify what db columns we have."""
        return inspect(self).attrs.keys()

Now we're going to define our model, inheriting the mixin:

class MyModel(db.Model, ModelMixin):
    id = db.Column(db.Integer, primary_key=True)
    foo = db.Column(...)
    bar = db.Column(...)
    # etc ...

That's all it takes to be able to pass an instance of MyModel() to dict() and get a real live dict instance out of it, which gets us quite a long way towards making jsonify() understand it. Next, we need to extend JSONEncoder to get us the rest of the way:

from flask.json import JSONEncoder
from contextlib import suppress

class MyJSONEncoder(JSONEncoder):
    def default(self, obj):
        # Optional: convert datetime objects to ISO format
        with suppress(AttributeError):
            return obj.isoformat()
        return dict(obj)

app.json_encoder = MyJSONEncoder

Bonus points: if your model contains computed fields (that is, you want your JSON output to contain fields that aren't actually stored in the database), that's easy too. Just define your computed fields as @propertys, and extend the keys() method like so:

class MyModel(db.Model, ModelMixin):
    id = db.Column(db.Integer, primary_key=True)
    foo = db.Column(...)
    bar = db.Column(...)

    @property
    def computed_field(self):
        return 'this value did not come from the db'

    def keys(self):
        return super().keys() + ['computed_field']

Now it's trivial to jsonify:

@app.route('/whatever', methods=['GET'])
def whatever():
    return jsonify(dict(results=MyModel.query.all()))

It is acceptable to use Module. Module is not used as a replacement for Class. Module serves its own purpose. The purpose of Module is to use as a container for

• extension methods,
• variables that are not specific to any Class, or
• variables that do not fit properly in any Class.

Module is not like a Class since you cannot

• inherit from a Module,
• implement an Interface with a Module,
• nor create an instance of a Module.

Anything inside a Module can be directly accessed within the Module assembly without referring to the Module by its name. By default, the access level for a Module is Friend.

Custom web font not working in IE9

Which includes a more descriptive breakdown of the CSS you see below (and explains the tweaks that make it work better on IE6-9).

@font-face {
  font-family: 'Bumble Bee';
  src: url('bumblebee-webfont.eot');
  src: local('?'),

  padding-bottom: 10px;
  font-family: 'GestaRegular', Arial, Helvetica, sans-serif;
}

h1 {
  font-family: "Bumble Bee", "Times New Roman", Georgia, Serif;
}

And your follow-up questions:

Q. I would like to use a font such as "Bumble bee," for example. How can I use @font-face to make that font available on the user's computer?

Note that I don't know what the name of your Bumble Bee font or file is, so adjust accordingly, and that the font-face declaration should precede (come before) your use of it, as I've shown above.

Q. Can I still use the other @font-face typeface "GestaRegular" as well? Can I use both in the same stylesheet?

Just list them together as I've shown in my example. There is no reason you can't declare both. All that @font-face does is instruct the browser to download and make a font-family available. See: http://iliadraznin.com/2009/07/css3-font-face-multiple-weights

After reading the accepted answer's comments, I tried the robocopy command, which worked for me (using the standard command prompt from Windows 7 64 bits SP 1):

robocopy source_dir dest_dir /s /e

What is "it" in the statement "it just says the procedure is completed"?

By default, most tools do not configure a buffer for dbms_output to write to and do not attempt to read from that buffer after code executes. Most tools, on the other hand, have the ability to do so. In SQL*Plus, you'd need to use the command set serveroutput on [size N|unlimited]. So you'd do something like

SQL> set serveroutput on size 30000;
SQL> exec print_actor_quotes( <<some value>> );

In SQL Developer, you'd go to View | DBMS Output to enable the DBMS Output window, then push the green plus icon to enable DBMS Output for a particular session.

Additionally, assuming that you don't want to print the literal "a.firstNamea.lastName" for every row, you probably want

FOR row IN quote_recs
LOOP
  DBMS_OUTPUT.PUT_LINE( row.firstName || ' ' || row.lastName );
END LOOP;

For more I recommend to get some literature.

Um... Why all the complications and tricks?

Rather then using DROP USER... You can simply delete the user from the mysql.user table (which doesn't throw an error if the user does not exist), and then flush privileges to apply the change.

DELETE FROM mysql.user WHERE User = 'SomeUser' AND Host = 'localhost';
FLUSH PRIVILEGES;

-- UPDATE --

I was wrong. It's not safe to delete the user like that. You do need to use DROP USER. Since it is possible to have mysql options set to not create users automatically via grants (an option I use), I still wouldn't recommend that trick. Here's a snipet from a stored procedure that works for me:

DECLARE userCount INT DEFAULT 0;
SELECT COUNT(*) INTO userCount FROM mysql.user WHERE User = userName AND Host='localhost';
IF userCount > 0 THEN
    SET @S=CONCAT("DROP USER ", userName, "@localhost" );
    PREPARE stmt FROM @S;
    EXECUTE stmt;
    SELECT CONCAT("DROPPED PRE-EXISTING USER: ", userName, "@localhost" ) as info;
END IF;
FLUSH PRIVILEGES;

So my contribution was for everyone trying to install IBM Integration Toolkit from IBM's Integration Bus bundle.

When you try to run "Installation Manager" command from folder /Integration_Toolkit/IM_Linux (the file to run is "install") you get the error showed in this post.

Further instructions to fix this problem you'll find in this IBM's web page: https://www-304.ibm.com/support/docview.wss?uid=swg21459143

Hope this helps for anybody trying to install that.

Try this complete and flexible solution. It works perfectly, and is based in-part by some previous answers, but contains additional validation checks, and gets rid of additional implied HTML from the loadHTML(...) function. It is divided into two separate functions (one with a previous dependency so don't re-order/rearrange) so you can use it with multiple HTML tags that you would like to remove simultaneously (i.e. not just 'script' tags). For example removeAllInstancesOfTag(...) function accepts an array of tag names, or optionally just one as a string. So, without further ado here is the code:

/* Remove all instances of a particular HTML tag (e.g. <script>...</script>) from a variable containing raw HTML data. [BEGIN] */

/* Usage Example: $scriptless_html = removeAllInstancesOfTag($html, 'script'); */

if (!function_exists('removeAllInstancesOfTag'))
    {
        function removeAllInstancesOfTag($html, $tag_nm)
            {
                if (!empty($html))
                    {
                        $html = mb_convert_encoding($html, 'HTML-ENTITIES', 'UTF-8'); /* For UTF-8 Compatibility. */
                        $doc = new DOMDocument();
                        $doc->loadHTML($html,LIBXML_HTML_NOIMPLIED|LIBXML_HTML_NODEFDTD|LIBXML_NOWARNING);

                        if (!empty($tag_nm))
                            {
                                if (is_array($tag_nm))
                                    {
                                        $tag_nms = $tag_nm;
                                        unset($tag_nm);

                                        foreach ($tag_nms as $tag_nm)
                                            {

                                    }
                                else if (is_string($tag_nm))
                                    {

                                            };
                                    };

And here is a test usage example:

$html = 'This is a JavaScript retention test.<br><br><span id="chk_frst_scrpt">Congratulations! The first \'script\' tag was successfully removed!</span><br><br><span id="chk_secd_scrpt">Congratulations! The second \'script\' tag was successfully removed!</span><script>document.getElementById("chk_frst_scrpt").innerHTML = "Oops! The first \'script\' tag was NOT removed!";</script><script>document.getElementById("chk_secd_scrpt").innerHTML = "Oops! The second \'script\' tag was NOT removed!";</script>';
echo removeAllScriptTags($html);

I hope my answer really helps someone. Enjoy!

Just for clarification, CorFlags.exe is part of the .NET Framework SDK. I have the development tools on my machine, and the simplest way for me determine whether a DLL is 32-bit only is to:

1. Open the Visual Studio Command Prompt (In Windows: menu Start/Programs/Microsoft Visual Studio/Visual Studio Tools/Visual Studio 2008 Command Prompt)

2. CD to the directory containing the DLL in question

3. Run corflags like this: corflags MyAssembly.dll

You will get output something like this:

Microsoft (R) .NET Framework CorFlags Conversion Tool.  Version  3.5.21022.8
Copyright (c) Microsoft Corporation.  All rights reserved.

CLR Header: 2.5
PE        : PE32
CorFlags  : 3
ILONLY    : 1
32BIT     : 1
Signed    : 0

As per comments the flags above are to be read as following:

• Any CPU: PE = PE32 and 32BIT = 0
• x86: PE = PE32 and 32BIT = 1
• 64-bit: PE = PE32+ and 32BIT = 0

I was getting this problem while using a tunnel because I:

1. had the tunnel url:port set in the FB app settings
2. but was accessing the local server by pointing my browser to "http://localhost:3000"

once i started punching the tunnel url:port into the browser, i was good to go.

i'm using Rails and Facebooker, but might help others just the same.

I have been in this position, especially with new hardware. I suggest you write a little hex dump routine of your own. You will be able to see the data, and the addresses they are at, shown all together. It's good practice and a confidence builder.

If you are on SQL Server 2012 (or newer):

Use the TRY_CONVERT function.

If you are on SQL Server 2005, 2008, or 2008 R2:

Create a user defined function. This will avoid the issues that Fedor Hajdu mentioned with regards to currency, fractional numbers, etc:

CREATE FUNCTION dbo.TryConvertInt(@Value varchar(18))
RETURNS int
AS
BEGIN
    SET @Value = REPLACE(@Value, ',', '')
    IF ISNUMERIC(@Value + 'e0') = 0 RETURN NULL
    IF ( CHARINDEX('.', @Value) > 0 AND CONVERT(bigint, PARSENAME(@Value, 1)) <> 0 ) RETURN NULL
    DECLARE @I bigint =
        CASE
        WHEN CHARINDEX('.', @Value) > 0 THEN CONVERT(bigint, PARSENAME(@Value, 2))
        ELSE CONVERT(bigint, @Value)
        END
    IF ABS(@I) > 2147483647 RETURN NULL
    RETURN @I
END
GO

-- Testing
DECLARE @Test TABLE(Value nvarchar(50))    -- Result
INSERT INTO @Test SELECT '1234'            -- 1234
INSERT INTO @Test SELECT '1,234'           -- 1234
INSERT INTO @Test SELECT '1234.0'          -- 1234
INSERT INTO @Test SELECT '-1234'           -- -1234
INSERT INTO @Test SELECT '$1234'           -- NULL
INSERT INTO @Test SELECT '1234e10'         -- NULL
INSERT INTO @Test SELECT '1234 5678'       -- NULL
INSERT INTO @Test SELECT '123-456'         -- NULL
INSERT INTO @Test SELECT '1234.5'          -- NULL
INSERT INTO @Test SELECT '123456789000000' -- NULL
INSERT INTO @Test SELECT 'N/A'             -- NULL
SELECT Value, dbo.TryConvertInt(Value) FROM @Test

Reference: I used this page extensively when creating my solution.

Another solution could be use the uncommit command to exclude specific file from current commit.

hg uncommit [file/directory]

This is very helpful when you want to keep current commit and deselect some files from commit (especially helpful for files/directories have been deleted).

Don't use grep. Download Silver Searcher or ripgrep. They're both outstanding, and way faster than grep or ack with tons of options.

Interestingly, when I replaced this:

$("body").trigger("click")

With this:

jQuery("body").trigger("click")

It works!

You can use this way because id can not be sequential in all cases.

SELECT * 
FROM  `ht_news` 
LIMIT 0 , 30

Unfortunately, there is still no multi-line commenting in R.

If your text editor supports column-mode, then use it to add a bunch of #s at once. If you use UltraEdit, Alt+c will put you in column mode.

Aggregate can also be used for same.

string[] test = new string[2];
test[0] = "Hello ";
test[1] = "World!";
string joinedString = test.Aggregate((prev, current) => prev + " " + current);

From the CLI the best way is to use grep like:

php -i | grep libxml

This code simulates a click on the burguer button to close the navbar by clicking on a link in the menu, keeping the fade out effect. Solution with typescript for angular 7. Avoid routerLink problems.

ToggleNavBar () {
    let element: HTMLElement = document.getElementsByClassName( 'navbar-toggler' )[ 0 ] as HTMLElement;
    if ( element.getAttribute( 'aria-expanded' ) == 'true' ) {
        element.click();
    }
}

<li class="nav-item" [routerLinkActive]="['active']">
    <a class="nav-link" [routerLink]="['link1']" title="link1" (click)="ToggleNavBar()">link1</a>
</li>

Think of the print statement as causing a side-effect, it makes your function write some text out to the user, but it can't be used by another function.

I'll attempt to explain this better with some examples, and a couple definitions from Wikipedia.

Here is the definition of a function from Wikipedia

A function, in mathematics, associates one quantity, the argument of the function, also known as the input, with another quantity, the value of the function, also known as the output..

Think about that for a second. What does it mean when you say the function has a value?

What it means is that you can actually substitute the value of a function with a normal value! (Assuming the two values are the same type of value)

Why would you want that you ask?

What about other functions that may accept the same type of value as an input?

def square(n):
    return n * n

def add_one(n):
    return n + 1

print square(12)

# square(12) is the same as writing 144

print add_one(square(12))
print add_one(144)
#These both have the same output

There is a fancy mathematical term for functions that only depend on their inputs to produce their outputs: Referential Transparency. Again, a definition from Wikipedia.

Referential transparency and referential opaqueness are properties of parts of computer programs. An expression is said to be referentially transparent if it can be replaced with its value without changing the behavior of a program

It might be a bit hard to grasp what this means if you're just new to programming, but I think you will get it after some experimentation. In general though, you can do things like print in a function, and you can also have a return statement at the end.

Just remember that when you use return you are basically saying "A call to this function is the same as writing the value that gets returned"

Python will actually insert a return value for you if you decline to put in your own, it's called "None", and it's a special type that simply means nothing, or null.

One suggestion is to use LINQ to Entity Framework only for single-record CRUD statements.

For more involved queries, searches, reporting, etc, write a stored procedure and add it to the Entity Framework model as described on MSDN.

This is the approach I've taken with a couple of my sites and it seems to be a good compromise between productivity and performance. Entity Framework will not always generate the most efficient SQL for the task at hand. And rather than spending the time to figure out why, writing a stored procedure for the more complex queries actually saves time for me. Once you're familiar with the process, it's not too much of a hassle to add stored procs to your EF model. And of course the benefit of adding it to your model is that you get all that strongly typed goodness that comes from using an ORM.

Something like:

var rnd = new Random(DateTime.Now.Millisecond);
int ticks = rnd.Next(0, 3000);

From search engines, I ended up on this topic for non-json posting data with fetch, so thought I would add this.

For non-json you don't have to use form data. You can simply set the Content-Type header to application/x-www-form-urlencoded and use a string:

fetch('url here', {
    method: 'POST',
    headers: {'Content-Type':'application/x-www-form-urlencoded'}, // this line is important, if this content-type is not set it wont work
    body: 'foo=bar&blah=1'
});

An alternative way to build that body string, rather then typing it out as I did above, is to use libraries. For instance the stringify function from query-string or qs packages. So using this it would look like:

import queryString from 'query-string'; // import the queryString class

fetch('url here', {
    method: 'POST',
    headers: {'Content-Type':'application/x-www-form-urlencoded'}, // this line is important, if this content-type is not set it wont work
    body: queryString.stringify({for:'bar', blah:1}) //use the stringify object of the queryString class
});

There is a mySQL bug report from 2004 that still seems to have some validity. It seems that in 4.x, this was fastest:

DROP table_name
CREATE TABLE table_name

TRUNCATE table_name was DELETE FROM internally back then, providing no performance gain.

This seems to have changed, but only in 5.0.3 and younger. From the bug report:

[11 Jan 2005 16:10] Marko Mäkelä

I've now implemented fast TRUNCATE TABLE, which will hopefully be included in MySQL 5.0.3.

Another alternative :

document.formname.elementname.disabled=true

Work on FF and IE ! :)

For a bit of completeness - this query will create a query to give you a count of all of the tables for a given owner.

select 
  DECODE(rownum, 1, '', ' UNION ALL ') || 
  'SELECT ''' || table_name || ''' AS TABLE_NAME, COUNT(*) ' ||
  ' FROM ' || table_name  as query_string 
 from all_tables 
where owner = :owner;

The output is something like

SELECT 'TAB1' AS TABLE_NAME, COUNT(*) FROM TAB1
 UNION ALL SELECT 'TAB2' AS TABLE_NAME, COUNT(*) FROM TAB2
 UNION ALL SELECT 'TAB3' AS TABLE_NAME, COUNT(*) FROM TAB3
 UNION ALL SELECT 'TAB4' AS TABLE_NAME, COUNT(*) FROM TAB4

Which you can then run to get your counts. It's just a handy script to have around sometimes.

I've patched my project with JailCoder http://jailcoder.com/ and problem resolved. Just download It and drag your xcode project to It.

The accepted answer is wrong. The quote is correct, the assertion that PUT and POST must have it is incorrect. There is no requirement that PUT or POST actually have additional content. Nor is there a prohibition against GET actually having content.

The RFCs say exactly what they mean .. IFF your side (client OR origin server) will be sending additional content, beyond the HTTP headers, it SHOULD specify a Content-Type header. But note it is allowable to omit the Content-Type and still include content (say, by using a Content-Length header).

Try this :

select {
    -webkit-appearance: none;
    -moz-appearance: none;
    appearance: none;
    padding: 2px 30px 2px 2px;
    border: none;
}

If you use Internet Explorer :

select {
    overflow:hidden;
    width: 120%;
}

wininet.dll returns both standard and non-standard status codes that are listed below.

401 - Unauthorized file
403 - Forbidden file
404 - File Not Found
500 - some inclusion or functions may missed
200 - Completed

12002 - Server timeout
12029,12030, 12031 - dropped connections (either web server or DB server)
12152 - Connection closed by server.
13030 - StatusText properties are unavailable, and a query attempt throws an exception

For the status code "zero" are you trying to do a request on a local webpage running on a webserver or without a webserver?

XMLHttpRequest status = 0 and XMLHttpRequest statusText = unknown can help you if you are not running your script on a webserver.

You can use following query to delete rows from multiple tables,

DELETE table1, table2, table3 FROM table1 INNER JOIN table2 INNER JOIN table3 WHERE table1.userid = table2.userid AND table2.userid = table3.userid AND table1.userid=3

I understood that you want to remove from the array using a condition and have another array that has items removed from the array. Is right?

How about this?

Hope this help...

By the way, I compared 'for-loop' to 'forEach'.

If remove in case a string contains 'f', a result is different.

var review = ["of", "concat", "copyWithin", "entries", "every", "fill", "filter", "find", "findIndex", "flatMap", "flatten", "forEach", "includes", "indexOf", "join", "keys", "lastIndexOf", "map", "pop", "push", "reduce", "reduceRight", "reverse", "shift", "slice", "some", "sort", "splice", "toLocaleString", "toSource", "toString", "unshift", "values"];_x000D_

And remove by each iteration, also a result is different.

For anyone who doesn't like none of the solutions posted above like me then you can simply implement a timer yourself and stop the request execution by throwing a runtime exception. Something like below:

                  try 
                 {
                     timer.schedule(new TimerTask() {
                       @Override
                       public void run() {
                         timer.cancel();
                       }
                     }, /* specify time of the requst */ 1000);
                 }
                 catch(Exception e)
                 {
                   throw new RuntimeException("the request is taking longer than usual");
                 }

   

or preferably use the java guava timeLimiter here

I've gotten the following to work:

html {
  background:
      linear-gradient(rgba(0,184,255,0.45),rgba(0,184,255,0.45)),
      url('bgimage.jpg') no-repeat center center fixed;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
}

The above will produce a nice opaque blue overlay.

Performance

Today 2020.05.13 I perform tests of chosen solutions on Chrome v81.0, Safari v13.1 and Firefox v76.0 on MacOs High Sierra v10.13.6.

Conclusions

• the slice(0,-1)(D) is fast or fastest solution for short and long strings and it is recommended as fast cross-browser solution
• solutions based on substring (C) and substr(E) are fast
• solutions based on regular expressions (A,B) are slow/medium fast
• solutions B, F and G are slow for long strings
• solution F is slowest for short strings, G is slowest for long strings

Details

I perform two tests for solutions A, B, C, D, E(ext), F, G(my)

• for 8-char short string (from OP question) - you can run it HERE
• for 1M long string - you can run it HERE

Solutions are presented in below snippet

function A(str) {
  return str.replace(/.$/, '');
}

function B(str) {
  return str.match(/(.*).$/)[1];
}

function C(str) {
  return str.substring(0, str.length - 1);
}

function D(str) {
  return str.slice(0, -1); 
}

function E(str) {
  return str.substr(0, str.length - 1);
}

function F(str) {
  let s= str.split("");
  s.pop();
  return s.join("");
}

function G(str) {
  let s='';
  for(let i=0; i<str.length-1; i++) s+=str[i];
  return s;
 }



// ---------
// TEST
// ---------

let log = (f)=>console.log(`${f.name}: ${f("12345.00")}`);

[A,B,C,D,E,F,G].map(f=>log(f));

This snippet only presents soutions

Here are example results for Chrome for short string

I had the same issue but solved it by using Ubuntu.

1. python -m pip install pyaudio
2. Install sudo, apt-get and then install homebrew &/ linuxbrew on your linux subsystem using Ubuntu.
3. The latest version supports ubuntu.
4. brew install portaudio
5. Make sure you have python/python3 installed on the terminal
6. Make sure the current location is added as path in your virtual computer's path in environment Variable.
7. brew link portaudio

I did a stupid mistake. I forgot to mention the class as public or open while updating code in cocoapod workspace.

Please do check whether accesor if working in separate workspace.

Note that the names generated by the RTTI feature of C++ is not portable. For example, the class

MyNamespace::CMyContainer<int, test_MyNamespace::CMyObject>

will have the following names:

// MSVC 2003:
class MyNamespace::CMyContainer[int,class test_MyNamespace::CMyObject]
// G++ 4.2:
N8MyNamespace8CMyContainerIiN13test_MyNamespace9CMyObjectEEE

So you can't use this information for serialization. But still, the typeid(a).name() property can still be used for log/debug purposes

Quoting is an issue if you're running awk from the command line. You'll sometimes need to use \, e.g. to quote ", but most of the time you'll use ^:

w:\srv>dir | grep ".txt" | awk "{ printf(\"echo %s@%s ^> %s.tstamp^\n\", $1, $2, $4); }"
echo 2014-09-07@22:21 > requirements-dev.txt.tstamp
echo 2014-11-28@18:14 > syncspec.txt.tstamp

Why not change the constructor on Production to let you pass in a reference at construction time:

public class Meter
{
   private int _powerRating = 0; 
   private Production _production;

   public Meter()
   {
      _production = new Production(this);
   }
}

In the Production constructor you can assign this to a private field or a property. Then Production will always have access to is parent.

Just as an alternative solution:

For me webView.getSettings().setUserAgentString("Android WebView") did the trick.

I already had implemented INTERNET permission and WebViewClient as well as WebChromeClient

You don't specify which shell (there are many), so I am assuming Bourne Shell, that is I think your script starts with:

#!/bin/sh

Please remember to tag future questions with the shell type, as this will help the community answer your question.

You need to define your functions before you call them. Using ():

process_install()
{
    echo "Performing process_install() commands, using arguments [${*}]..."
}

process_exit()
{
    echo "Performing process_exit() commands, using arguments [${*}]..."
}

Then you can call your functions, just as if you were calling any command:

if [ "$choice" = "true" ]
then
    process_install foo bar
elif [ "$choice" = "false" ]
then
    process_exit baz qux

You may also wish to check for invalid choices at this juncture...

else
    echo "Invalid choice [${choice}]..."
fi

See it run with three different values of ${choice}.

Good luck!

There is an article available in which explains how to perform multiple deletion paths using triggers. Maybe this is useful for complex scenarios.

If you don't have a company, leave your name, it doesn't matter as long as both bundle id in info.plist file and the one you've submitted in iTunes Connect match.

In Bundle ID Suffix you should write full name of bundle ID.

Example:

Bundle ID suffix = thebestapp (NOT CORRECT!!!!)

Bundle ID suffix = com.awesomeapps.thebestapp (CORRECT!!)

The reason for this is explained in the Developer Portal:

The App ID string contains two parts separated by a period (.) — an App ID Prefix (your Team ID by default, e.g. ABCDE12345), and an App ID Suffix (a Bundle ID search string, e.g. com.mycompany.appname). [emphasis added]

So in this case the suffix is the full string com.awesomeapps.thebestapp.

I fixed this by adding ChangeDetectionStrategy from angular core.

import {  Component, ChangeDetectionStrategy } from '@angular/core';
@Component({
  changeDetection: ChangeDetectionStrategy.OnPush,
  selector: 'page1',
  templateUrl: 'page1.html',
})

Adding to above answers, take a look at following. AppointmentForm's date column is annotated with couple of annotations. By having @Valid annotation that triggers validations on the AppointmentForm (in this case @NotNull and @Future). These annotations could come from different JSR-303 providers (e.g, Hibernate, Spring..etc).

    @RequestMapping(value = "/appointments", method = RequestMethod.POST)
    public String add(@Valid AppointmentForm form, BindingResult result) {
        ....
    }

    static class AppointmentForm {

        @NotNull @Future
        private Date date;
    }

Using your code, this is how I would do it. I know an answer was chosen, just giving additional options.

data = json.loads('{"lat":444, "lon":555}')
    ret = ''
    for j in data:
        ret = ret+" "+data[j]
return ret

When you use for in this manor you get the key of the object, not the value, so you can get the value, by using the key as an index.

Simple answer

If you are behind a proxy server, please set the proxy for curl. The curl is not able to connect to server so it shows wrong version number. Set proxy by opening subl ~/.curlrc or use any other text editor. Then add the following line to file: proxy= proxyserver:proxyport For e.g. proxy = 10.8.0.1:8080

If you are not behind a proxy, make sure that the curlrc file does not contain the proxy settings.

string[] allfiles = Directory.GetFiles("path/to/dir", "*.*", SearchOption.AllDirectories);

where *.* is pattern to match files

If the Directory is also needed you can go like this:

 foreach (var file in allfiles){
     FileInfo info = new FileInfo(file);
 // Do something with the Folder or just add them to a list via nameoflist.add();
 }

In Python inside there is a good use of container called a named tuple, it can be used to create a definition of class and has all the features of the original tuple.

Using named tuple will be directly applied to the default class template to generate a simple class, this method allows a lot of code to improve readability and it is also very convenient when defining a class.

WebSocket is basically an application protocol (with reference to the ISO/OSI network stack), message-oriented, which makes use of TCP as transport layer.

The idea behind the WebSocket protocol consists of reusing the established TCP connection between a Client and Server. After the HTTP handshake the Client and Server start speaking WebSocket protocol by exchanging WebSocket envelopes. HTTP handshaking is used to overcome any barrier (e.g. firewalls) between a Client and a Server offering some services (usually port 80 is accessible from anywhere, by anyone). Client and Server can switch over speaking HTTP in any moment, making use of the same TCP connection (which is never released).

Behind the scenes WebSocket rebuilds the TCP frames in consistent envelopes/messages. The full-duplex channel is used by the Server to push updates towards the Client in an asynchronous way: the channel is open and the Client can call any futures/callbacks/promises to manage any asynchronous WebSocket received message.

To put it simply, WebSocket is a high level protocol (like HTTP itself) built on TCP (reliable transport layer, on per frame basis) that makes possible to build effective real-time application with JS Clients (previously Comet and long-polling techniques were used to pull updates from the Server before WebSockets were implemented. See Stackoverflow post: Differences between websockets and long polling for turn based game server ).

If you are using google-colab simple visualization of the graph would be :

import tensorboardcolab as tb

tbc = tb.TensorBoardColab()
tensorboard = tb.TensorBoardColabCallback(tbc)


history = model.fit(x_train,# Features
                    y_train, # Target vector
                    batch_size=batch_size, # Number of observations per batch
                    epochs=epochs, # Number of epochs
                    callbacks=[early_stopping, tensorboard], # Early stopping
                    verbose=1, # Print description after each epoch
                    validation_split=0.2, #used for validation set every each epoch
                    validation_data=(x_test, y_test)) # Test data-set to evaluate the model in the end of training

Except for the answer by @Ed G, all of the answers require knowing which bound is the lower and which is the upper one.

Here's a (rather non-obvious) way of doing it when you don't know which bound is which.

  /// <summary>
  /// Method to test if a value is "between" two other values, when the relative magnitude of 
  /// the two other values is not known, i.e., number1 may be larger or smaller than number2. 
  /// The range is considered to be inclusive of the lower value and exclusive of the upper 
  /// value, irrespective of which parameter (number1 or number2) is the lower or upper value. 
  /// This implies that if number1 equals number2 then the result is always false.
  /// 
  /// This was extracted from a larger function that tests if a point is in a polygon:
  /// http://www.ecse.rpi.edu/Homepages/wrf/Research/Short_Notes/pnpoly.html
  /// </summary>
  /// <param name="testValue">value to be tested for being "between" the other two numbers</param>
  /// <param name="number1">one end of the range</param>
  /// <param name="number2">the other end of the range</param>
  /// <returns>true if testValue >= lower of the two numbers and less than upper of the two numbers,
  ///          false otherwise, incl. if number1 == number2</returns>
  private static bool IsInRange(T testValue, T number1, T number2)
  {
     return (testValue <= number1) != (testValue <= number2);
  }

Note: This is NOT a generic method; it is pseudo code. The T in the above method should be replaced by a proper type, "int" or "float" or whatever. (There are ways of making this generic, but they're sufficiently messy that it's not worth while for a one-line method, at least not in most situations.)

I believe the standard MIME type for Excel files is application/vnd.ms-excel.

Regarding the name of the document, you should set the following header in the response:

header('Content-Disposition: attachment; filename="name_of_excel_file.xls"');

"Just because you can doesn't mean you should."

You can probably use async/await in LINQ expressions such that it will behave exactly as you want it to, but will any other developer reading your code still understand its behavior and intent?

(In particular: Should the async operations be run in parallel or are they intentionally sequential? Did the original developer even think about it?)

This is also shown clearly by the question, which seems to have been asked by a developer trying to understand someone else's code, without knowing its intent. To make sure this does not happen again, it may be best to rewrite the LINQ expression as a loop statement, if possible.

It’s very old, but it is still useful.

The difference is that Thread.start() starts a thread that calls the run() method, while Runnable.run() just calls the run() method on the current thread.

Handling listView scrolling using UP/ Down using.button

If someone is interested in handling listView one row up/down using button. then.

public View.OnClickListener onChk = new View.OnClickListener() {
             public void onClick(View v) {

                 int index = list.getFirstVisiblePosition();
                 getListView().smoothScrollToPosition(index+1); // For increment. 

}
});

I have met this issue , the error comes out since the error transactions hasn't been ended rightly, I found the postgresql_transactions of Transaction Control command here

Transaction Control

The following commands are used to control transactions

BEGIN TRANSACTION - To start a transaction.

COMMIT - To save the changes, alternatively you can use END TRANSACTION command.

ROLLBACK - To rollback the changes.

so i use the END TRANSACTION to end the error TRANSACTION, code like this:

    for key_of_attribute, command in sql_command.items():
        cursor = connection.cursor()
        g_logger.info("execute command :%s" % (command))
        try:
            cursor.execute(command)
            rows = cursor.fetchall()
            g_logger.info("the command:%s result is :%s" % (command, rows))
            result_list[key_of_attribute] = rows
            g_logger.info("result_list is :%s" % (result_list))
        except Exception as e:
            cursor.execute('END TRANSACTION;')
            g_logger.info("error command :%s and error is :%s" % (command, e))
    return result_list

color and fill are separate aesthetics. Since you want to modify the color you need to use the corresponding scale:

d + scale_color_manual(values=c("#CC6666", "#9999CC"))

is what you want.

Yes there is, you can simply put <hr> in your code where you want it, I already use it in one of my admin panel side bar.

In my case, a file has USC-2 LE BOM encoding, according to Notepad++. It is encoding="utf_16_le" for python.

Hope, it helps to find an answer a bit faster for someone.

I use ? (0x25B8) for the right arrow, often to show a collapsed list; and I pair it with ? (0x25BE) to show the list opened up. Both are unobtrusive.

You are using a pathname separator which is platform dependent. Windows uses "\" and Unix uses "/".

npm install [email protected] installs the previous version, if it helps.

I know in 3.x the view layout mechanic was removed, but this might not be your problem. Also replace express.createServer() with express()

Update:

It's your __dirname from environment.js
It should be:

app.use(express.static(__dirname + '../public'));

You can't use PHP in the WordPress back-end Page editor. Maybe with a plugin you can, but not out of the box.

The easiest solution for this is creating a shortcode. Then you can use something like this

function input_func( $atts ) {
    extract( shortcode_atts( array(
        'type' => 'text',
        'name' => '',
    ), $atts ) );

    return '<input name="' . $name . '" id="' . $name . '" value="' . (isset($_GET\['from'\]) && $_GET\['from'\] ? $_GET\['from'\] : '') . '" type="' . $type . '" />';
}
add_shortcode( 'input', 'input_func' );

See the Shortcode_API.

library(lubridate) if your date format is like this '04/24/2017 05:35:00'then change it like below prods.all$Date2<-gsub("/","-",prods.all$Date2) then change the date format parse_date_time(prods.all$Date2, orders="mdy hms")

You can do so from within vim and use its own windows or tabs.

One way to go is to utilize the built-in file explorer; activate it via :Explore, or :Texplore for a tabbed interface (which I find most comfortable).

:Texplore (and :Sexplore) will also guard you from accidentally exiting the current buffer (editor) on :q once you're inside the explorer.

To toggle between open tabs when using tab pages use gt or gT (next tab and previous tab, respectively).

See also Using tab pages on the vim wiki.

Create openssl.conf file:

[req]
default_bits = 2048
default_keyfile = oats.key
encrypt_key = no
utf8 = yes
distinguished_name = req_distinguished_name
x509_extensions = v3_req
prompt = no

[req_distinguished_name]
C = US
ST = Cary
L = Cary
O  = BigCompany
CN = *.myserver.net

[v3_req]
keyUsage = critical, digitalSignature, keyAgreement
extendedKeyUsage = serverAuth
subjectAltName = @alt_names

[alt_names]
DNS.1 = myserver.net
DNS.2 = *.myserver.net

Run this comand:

openssl req -x509 -sha256 -nodes -days 3650 -newkey rsa:2048 -keyout app.key -out app.crt  -config openssl.conf

Output files app.crt and app.key work for me.

Then use + to combine strings:

console.log("story " + name + " story");

Instead of using position: absolute, text-indent can be used to solve the "inside" problem:

li {
    list-style: inherit;
    margin: 0 0 4px 9px;
    text-indent: -9px;
}
li:before {
    content: "· ";
}

You can't launch arbitrary commands, but if your users are willing to go through some extra setup, you can use custom protocols.

E.g. you have the users set things up so that some-app:// links start "SomeApp", and then in my-awesome-extension you open a tab pointing to some-app://some-data-the-app-wants, and you're good to go!

Think of it as a letter. Sometimes you get a letter, say asking you to fill in a form then return the form in a pre-addressed envelope which is in the original envelope that was housing the form.

Once you have finished filling the form in, you put it in the provided return envelop and send it back.

The callbackUrl is like that return envelope. You are basically saying I am sending you this data. Once you are done with it, I am on this callbackUrl waiting for your response. So the API will process the data you have sent then look at the callback to send you the response.

This is useful because sometimes you may take ages to process some data and it makes no sense to have the caller wait for a response. For example, say your API allows users to send documents to it and virus scan them. Then you send a report after. The scan could take maybe 3minutes. The user cannot be waiting for 3minutes. So you acknowledge that you got the document and let the caller get on with other business while you do the scan then use the callbackUrl when done to tell them the result of the scan.

It doesn't - the C# compiler does :)

So this code:

string x = "hello";
string y = "there";
string z = "chaps";
string all = x + y + z;

actually gets compiled as:

string x = "hello";
string y = "there";
string z = "chaps";
string all = string.Concat(x, y, z);

(Gah - intervening edit removed other bits accidentally.)

The benefit of the C# compiler noticing that there are multiple string concatenations here is that you don't end up creating an intermediate string of x + y which then needs to be copied again as part of the concatenation of (x + y) and z. Instead, we get it all done in one go.

EDIT: Note that the compiler can't do anything if you concatenate in a loop. For example, this code:

string x = "";
foreach (string y in strings)
{
    x += y;
}

just ends up as equivalent to:

string x = "";
foreach (string y in strings)
{
    x = string.Concat(x, y);
}

... so this does generate a lot of garbage, and it's why you should use a StringBuilder for such cases. I have an article going into more details about the two which will hopefully answer further questions.

Angular provides filters to modify a collection. In this case the collection would be null, i.e. [], and the filter also takes arguments, as follows:

<div id="demo">
    <ul>
        <li ng-repeat="not in []|fixedNumber:number track by $index">{{$index}}</li>
    </ul>
</div>

JS:

module.filter('fixedNumber', function() {
    return function(emptyarray, number) {
        return Array(number);
    }
});

module.controller('myCtrl', ['$scope', function($scope) {
    $scope.number = 5;
}]);

This method is very similar to those proposed above and isn't necessarily superior but shows the power of filters in AngularJS.

Remember that HTML and XML are two distinct concepts in the tree of markup languages. You can't exactly replace HTML with XML . XML can be viewed as a generalized form of HTML, but even that is imprecise. You mainly use HTML to display data, and XML to carry(or store) the data.

This link is helpful: How to read HTML as XML?

In my case I was accusing that the '*service.ts' is not a module.

To solve it I just added the service within providers in the module.

Swift 3 (forget about NSURL).

let fileName = "20-01-2017 22:47"
let folderString = "file:///var/mobile/someLongPath"

To make a URL out of a string:

let folder: URL? = Foundation.URL(string: folderString)
// Optional<URL>
//  ? some : file:///var/mobile/someLongPath

If we want to add the filename. Note, that appendingPathComponent() adds the percent encoding automatically:

let folderWithFilename: URL? = folder?.appendingPathComponent(fileName)
// Optional<URL>
//  ? some : file:///var/mobile/someLongPath/20-01-2017%2022:47

When we want to have String but without the root part (pay attention that percent encoding is removed automatically):

let folderWithFilename: String? = folderWithFilename.path
// ? Optional<String>
//  - some : "/var/mobile/someLongPath/20-01-2017 22:47"

If we want to keep the root part we do this (but mind the percent encoding - it is not removed):

let folderWithFilenameAbsoluteString: String? = folderWithFilenameURL.absoluteString
// ? Optional<String>
//  - some : "file:///var/mobile/someLongPath/20-01-2017%2022:47"

To manually add the percent encoding for a string:

let folderWithFilenameAndEncoding: String? = folderWithFilename.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed)
// ? Optional<String>
//  - some : "/var/mobile/someLongPath/20-01-2017%2022:47"

To remove the percent encoding:

let folderWithFilenameAbsoluteStringNoEncodig: String? = folderWithFilenameAbsoluteString.removingPercentEncoding
// ? Optional<String>
//  - some : "file:///var/mobile/someLongPath/20-01-2017 22:47"

The percent-encoding is important because URLs for network requests need them, while URLs to file system won't always work - it depends on the actual method that uses them. The caveat here is that they may be removed or added automatically, so better debug these conversions carefully.

To clarify, the syntax is as follows for MongoDB version 4.0.x:

db.collection.update({},{$set: {"new_field*":1}},false,true)

Here is a working example adding a published field to the articles collection and setting the field's value to true:

db.articles.update({},{$set: {"published":true}},false,true)

You can't use float inside flex container and the reason is that float property does not apply to flex-level boxes as you can see here Fiddle.

So if you want to position child element to right of parent element you can use margin-left: auto but now child element will also push other div to the right as you can see here Fiddle.

What you can do now is change order of elements and set order: 2 on child element so it doesn't affect second div

.parent {_x000D_
  display: flex;_x000D_
}_x000D_
.child {_x000D_
  margin-left: auto;_x000D_
  order: 2;_x000D_
}

<div class="parent">_x000D_
  <div class="child">Ignore parent?</div>_x000D_
  <div>another child</div>_x000D_
</div>

• .NET 4.6 and above. You don’t need to do any additional work to support TLS 1.2, it’s supported by default.

• .NET 4.5. TLS 1.2 is supported, but it’s not a default protocol. You need to opt-in to use it. The following code will make TLS 1.2 default, make sure to execute it before making a connection to secured resource:
  ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12

• .NET 4.0. TLS 1.2 is not supported, but if you have .NET 4.5 (or above) installed on the system then you still can opt in for TLS 1.2 even if your application framework doesn’t support it. The only problem is that SecurityProtocolType in .NET 4.0 doesn’t have an entry for TLS1.2, so we’d have to use a numerical representation of this enum value:
  ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12

• .NET 3.5 or below. TLS 1.2 is not supported. Upgrade your application to more recent version of the framework.

I had put a not encrypted password in the settings.xml .

I tested the call with curl

curl -u username:password http://url/artifactory/libs-snapshot-local/com/myproject/api/1.0-SNAPSHOT/api-1.0-20160128.114425-1.jar --request PUT --data target/api-1.0-SNAPSHOT.jar 

and I got the error:

{
  "errors" : [ {
    "status" : 401,
    "message" : "Artifactory configured to accept only encrypted passwords but received a clear text password."
  } ]
}

I retrieved my encrypted password clicking on my artifactory profile and unlocking it.

In my case I need to do

sudo npm install  

my project is inside /var/www so I also need to set proper permissions.

Addition to previous answer make sure that your curl installation supports https.
You can use curl --version to get information about supported protocols.

If your curl supports https follow the previous answer.

curl --cert certificate_path:password https://www.example.com

If it does not support https, you need to install a cURL version that supports https.

This works for me

msg.BodyFormat = MailFormat.Html;

and then you can use html in your body

msg.Body = "<em>It's great to use HTML in mail!!</em>"

I know that you can modify a javascript file when using Google Chrome.

1. Open up Chrome Inspector, go to the "Scripts" tab.
2. Press the drop-down menu and select the javascript file that you want to edit.
3. Double click in the text field, type in what ever you want and delete whatever you want.
4. Then all you have to do is press Ctrl + S to save the file.

Warning: If you refresh the page, all changes will go back to original file. I recommend to copy/paste the code somewhere else if you want to use it again.

Hope this helps!

In Java 8,

For small files:

String line = Files.readAllLines(Paths.get("file.txt")).get(n);

For large files:

String line;
try (Stream<String> lines = Files.lines(Paths.get("file.txt"))) {
    line = lines.skip(n).findFirst().get();
}

In Java 7

String line;
try (BufferedReader br = new BufferedReader(new FileReader("file.txt"))) {
    for (int i = 0; i < n; i++)
        br.readLine();
    line = br.readLine();
}

Jesse Beder's solution is likely the best, but if you don't like the names typeid gives you (I think gcc gives you mangled names for instance), you can do something like:

template<typename T>
struct TypeParseTraits;

#define REGISTER_PARSE_TYPE(X) template <> struct TypeParseTraits<X> \
    { static const char* name; } ; const char* TypeParseTraits<X>::name = #X


REGISTER_PARSE_TYPE(int);
REGISTER_PARSE_TYPE(double);
REGISTER_PARSE_TYPE(FooClass);
// etc...

And then use it like

throw ParseError(TypeParseTraits<T>::name);

EDIT:

You could also combine the two, change name to be a function that by default calls typeid(T).name() and then only specialize for those cases where that's not acceptable.

Old way:

SELECT DATE_COLUMN + 1 is adding a day
SELECT DATE_COLUMN + N /24 to add hour(s) - N being number of hours
SELECT DATE_COLUMN + N /1440 to add minute(s) - N being number of minutes
SELECT DATE_COLUMN + N /86400 to add second(s) - N being number of seconds

Using INTERVAL:

SELECT DATE_COLUMN + INTERVAL 'N' HOUR or MINUTE or SECOND - N being a number of hours or minutes or seconds.

I imagine a lot of data comes into Pandas from CSV files, in which case you can simply convert the date during the initial CSV read:

dfcsv = pd.read_csv('xyz.csv', parse_dates=[0]) where the 0 refers to the column the date is in.
You could also add , index_col=0 in there if you want the date to be your index.

See https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.read_csv.html

This question is old. But I would like to mention an other approach. Using Enums for declaring constant values. Based on the answer of Nandkumar Tekale, the Enum can be used as below:

Enum:

public enum Planck {
    REDUCED();
    public static final double PLANCK_CONSTANT = 6.62606896e-34;
    public static final double PI = 3.14159;
    public final double REDUCED_PLANCK_CONSTANT;

    Planck() {
        this.REDUCED_PLANCK_CONSTANT = PLANCK_CONSTANT / (2 * PI);
    }

    public double getValue() {
        return REDUCED_PLANCK_CONSTANT;
    }
}

Client class:

public class PlanckClient {

    public static void main(String[] args) {
        System.out.println(getReducedPlanckConstant());
        // or using Enum itself as below:
        System.out.println(Planck.REDUCED.getValue());
    }

    public static double getReducedPlanckConstant() {
        return Planck.PLANCK_CONSTANT / (2 * Planck.PI);
    }

}

Reference : The usage of Enums for declaring constant fields is suggested by Joshua Bloch in his Effective Java book.

This worked for me - just changed INSERT to UPDATE for my table.

INSERT INTO Yourtable (Field1, YourDateField) VALUES('val1', (select now()))

I listed dates of 2 Weeks later. You can use variable @period OR function datediff(dd, @date_start, @date_end)

declare @period INT, @date_start datetime, @date_end datetime, @i int;

set @period = 14
set @date_start = convert(date,DATEADD(D, -@period, curent_timestamp))
set @date_end = convert(date,current_timestamp)
set @i = 1

create table #datesList(dts datetime)
insert into #datesList values (@date_start)
while @i <= @period
    Begin
        insert into #datesList values (dateadd(d,@i,@date_start))
        set @i = @i + 1
    end
select cast(dts as DATE) from #datesList
Drop Table #datesList

take example if we want to compare "a" and "b", i.e ("a" == this)

1. negative int if a < b
2. if a == b
3. Positive int if a > b

Checkout this jquery window plugin: http://fstoke.me/jquery/window/

// create a window
sampleWnd = $.window({
   .....
});

// resize the window by passed w,h parameter
sampleWnd.resize(screen.width, screen.height);

If your dates column does not contain time information, you could get away with:

WHERE dates BETWEEN '20121211' and '20121213'

However, given your dates column is actually datetime, you want this

WHERE dates >= '20121211'
  AND dates < '20121214'  -- i.e. 00:00 of the next day

Another option for SQL Server 2008 onwards that retains SARGability (ability to use index for good performance) is:

WHERE CAST(dates as date) BETWEEN '20121211' and '20121213'

Note: always use ISO-8601 format YYYYMMDD with SQL Server for unambiguous date literals.

I just came across this technique in the book Effective JavaScript that is pretty simple:

Since NaN is the only JavaScript value that is treated as unequal to itself, you can always test if a value is NaN by checking it for equality to itself:

var a = NaN;
a !== a; // true 

var b = "foo";
b !== b; // false 

var c = undefined; 
c !== c; // false

var d = {};
d !== d; // false

var e = { valueOf: "foo" }; 
e !== e; // false

Didn't realize this until @allsyed commented, but this is in the ECMA spec: https://tc39.github.io/ecma262/#sec-isnan-number

Since jQuery.get is just a shorthand for jQuery.ajax, another way would be to use the latter one's context option, as stated in the documentation:

The this reference within all callbacks is the object in the context option passed to $.ajax in the settings; if context is not specified, this is a reference to the Ajax settings themselves.

So you would use

$.ajax('http://www.example.org', {
  dataType: 'xml',
  data: {'a':1,'b':2,'c':3},
  context: {
    url: 'http://www.example.org'
  }
}).done(function(xml) {alert(this.url});

Stopwatch is fine, but loop the work 10^6 times, then divide by 10^6. You'll get a lot more precision.

Using "VanillaJS" means using plain JavaScript without any additional libraries like jQuery.

People use it as a joke to remind other developers that many things can be done nowadays without the need for additional JavaScript libraries.

Here's a funny site that jokingly talks about this: http://vanilla-js.com/

The correct answer is this (example version):

• In parent pom.xml you should have (not inside properties):

  <version>0.0.1-SNAPSHOT</version>
  

• In all child modules you should have:

  <parent>
      <groupId>com.vvirlan</groupId>
      <artifactId>grafiti</artifactId>
      <version>0.0.1-SNAPSHOT</version>
  </parent>
  

So it is hardcoded.

Now, to update the version you do this:

mvn versions:set -DnewVersion=0.0.2-SNAPSHOT
mvn versions:commit # Necessary to remove the backup file pom.xml

and all your 400 modules will have the parent version updated.

To run app.js file check "main": "app.js" in your package.json file.

Then run command $ node app.js That should run your app and check.
