Yes. You can use reflection. Something like this:

Type thisType = this.GetType();
MethodInfo theMethod = thisType.GetMethod(TheCommandString);
theMethod.Invoke(this, userParameters);

Code below does not print boolean, but allows for dataframe subsetting by index... I understand this is likely not the most efficient way to solve the problem, but I (1) like the way this reads and (2) you can easily subset where df1 index exists in df2:

df3 = df1[df1.index.isin(df2.index)]

or where df1 index does not exist in df2...

df3 = df1[~df1.index.isin(df2.index)]

it works :

export PATH=/home/yourUserName/anaconda3/bin:$PATH

after that run anaconda-navigator command. remember anaconda can't in Sudo mode, so don't use sudo at all.

You could just do: String s = Integer.valueOf("0001007").toString();

If you're looking for, say two decimal places.. Float f = (float)12.34; String s = new DecimalFormat ("#.00").format (f);

You just missed an extra pair of brackets for the "OR" symbol. The following should do the trick:

([0-9]+)\s+((\bseconds\b)|(\bminutes\b))

Without those you were either matching a number followed by seconds OR just the word minutes

It can be done by three different ways,though all them are nearly the same

Javascript way

document.getElementById('test').value

Jquery way

$("#test").val()          

$("#test")[0].value             

$("#test").get(0).value

By declaring it global inside the function that accesses it:

g_c = 0

class TestClass():
    def run(self):
        global g_c
        for i in range(10):
            g_c = 1
            print(g_c)

The Python documentation says this, about the global statement:

The global statement is a declaration which holds for the entire current code block.

UIView's also have a center property. If you just want to move the position rather than resize, you can just change that - eg:

aView.center = CGPointMake(50, 200);

Otherwise you would do it the way you posted.

None of the answers so far offer a complete solution. There are quite a few issues to address:

1. Not all keypresses are passed onto keydown and keypress handlers (e.g. backspace and delete keys are suppressed by some browsers).
2. Handling keydown is not a good idea. There are situations where a keydown does NOT result in a keypress!
3. setTimeout() style solutions get delayed under Google Chrome/Blink web browsers until the user stops typing.
4. Mouse and touch events may be used to perform actions such as cut, copy, and paste. Those events will not trigger keyboard events.
5. The browser, depending on the input method, may not deliver notification that the element has changed until the user navigates away from the field.

A more correct solution will handle the keypress, keyup, input, and change events.

Example:

<p><input id="editvalue" type="text"></p>
<p>The text box contains: <span id="labelvalue"></span></p>

<script>
function UpdateDisplay()
{
    var inputelem = document.getElementById("editvalue");
    var s = inputelem.value;

    var labelelem = document.getElementById("labelvalue");
    labelelem.innerText = s;
}

// Initial update.
UpdateDisplay();

// Register event handlers.
var inputelem = document.getElementById("editvalue");
inputelem.addEventListener('keypress', UpdateDisplay);
inputelem.addEventListener('keyup', UpdateDisplay);
inputelem.addEventListener('input', UpdateDisplay);
inputelem.addEventListener('change', UpdateDisplay);
</script>

Fiddle:

Handling all four events catches all of the edge cases. When working with input from a user, all types of input methods should be considered and cross-browser and cross-device functionality should be verified. The above code has been tested in Firefox, Edge, and Chrome on desktop as well as the mobile devices I own.

The following code is what I'm using:

var altKeyDownCount = 0;
window.onkeydown = function (e) {
    if (!e) e = window.event;
    if (e.altKey) {
        altKeyDownCount++;
        if (30 < altKeyDownCount) {
            $('.key').removeClass('hidden');
            altKeyDownCount = 0;
        }
        return false;
    }
}

window.onkeyup = function (e) {
    if (!e) e = window.event;
    altKeyDownCount = 0;
    $('.key').addClass('hidden');
}

When the user keeps holding down the Alt key for some time (about 2 seconds), a group of labels (class='key hidden') appears. When the Alt key is released, the labels disappear. jQuery and Bootstrap are both used.

1. Add using

using System.ComponentModel;

2. Declare Background Worker:

private readonly BackgroundWorker worker = new BackgroundWorker();

3. Subscribe to events:

worker.DoWork += worker_DoWork;
worker.RunWorkerCompleted += worker_RunWorkerCompleted;

4. Implement two methods:

private void worker_DoWork(object sender, DoWorkEventArgs e)
{
  // run all background tasks here
}

private void worker_RunWorkerCompleted(object sender, 
                                           RunWorkerCompletedEventArgs e)
{
  //update ui once worker complete his work
}

5. Run worker async whenever your need.

worker.RunWorkerAsync();

6. Track progress (optional, but often useful)

   a) subscribe to ProgressChanged event and use ReportProgress(Int32) in DoWork

   b) set worker.WorkerReportsProgress = true; (credits to @zagy)

To set your ImageView equal to half the screen, you need to add the following to your XML for the ImageView:

<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_centerInParent="true"
    android:scaleType="fitXY"
    android:adjustViewBounds="true"/>

To then set the height equal to this width, you need to do it in code. In the getView method of your GridView adapter, set the ImageView height equal to its measured width:

mImageView.getLayoutParams().height = mImageView.getMeasuredWidth();

I am using the org.json library and found it to be nice and friendly.

Example:

String jsonString = new JSONObject()
                  .put("JSON1", "Hello World!")
                  .put("JSON2", "Hello my World!")
                  .put("JSON3", new JSONObject().put("key1", "value1"))
                  .toString();

System.out.println(jsonString);

OUTPUT:

{"JSON2":"Hello my World!","JSON3":{"key1":"value1"},"JSON1":"Hello World!"}

I've got a handy extension method that uses TryParse, as IsDefined is case-sensitive.

public static bool IsParsable<T>(this string value) where T : struct
{
    return Enum.TryParse<T>(value, true, out _);
}

Binary Tree is a specialized form of tree with two child (left child and right Child). It is simply representation of data in Tree structure

Binary Search Tree (BST) is a special type of Binary Tree that follows following condition:

1. left child node is smaller than its parent Node
2. right child node is greater than its parent Node

Adding a requestedExecutionLevel element to your manifest is only half the battle; you have to remember that UAC can be turned off. If it is, you have to perform the check the old school way and put up an error dialog if the user is not administrator
(call IsInRole(WindowsBuiltInRole.Administrator) on your thread's CurrentPrincipal).

My understanding of SQLiteDatabase APIs is that in case you have a multi threaded application, you cannot afford to have more than a 1 SQLiteDatabase object pointing to a single database.

The object definitely can be created but the inserts/updates fail if different threads/processes (too) start using different SQLiteDatabase objects (like how we use in JDBC Connection).

The only solution here is to stick with 1 SQLiteDatabase objects and whenever a startTransaction() is used in more than 1 thread, Android manages the locking across different threads and allows only 1 thread at a time to have exclusive update access.

Also you can do "Reads" from the database and use the same SQLiteDatabase object in a different thread (while another thread writes) and there would never be database corruption i.e "read thread" wouldn't read the data from the database till the "write thread" commits the data although both use the same SQLiteDatabase object.

This is different from how connection object is in JDBC where if you pass around (use the same) the connection object between read and write threads then we would likely be printing uncommitted data too.

In my enterprise application, I try to use conditional checks so that the UI Thread never have to wait, while the BG thread holds the SQLiteDatabase object (exclusively). I try to predict UI Actions and defer BG thread from running for 'x' seconds. Also one can maintain PriorityQueue to manage handing out SQLiteDatabase Connection objects so that the UI Thread gets it first.

It's fatal. The remote server has sent you a RST packet, which indicates an immediate dropping of the connection, rather than the usual handshake. This bypasses the normal half-closed state transition. I like this description:

"Connection reset by peer" is the TCP/IP equivalent of slamming the phone back on the hook. It's more polite than merely not replying, leaving one hanging. But it's not the FIN-ACK expected of the truly polite TCP/IP converseur.

Here are some of your options:

char a1[][14] = { "blah", "hmm" };
char* a2[] = { "blah", "hmm" };
char (*a3[])[] = { &"blah", &"hmm" };  // only since you brought up the syntax -

printf(a1[0]); // prints blah
printf(a2[0]); // prints blah
printf(*a3[0]); // prints blah

The advantage of a2 is that you can then do the following with string literals

a2[0] = "hmm";
a2[1] = "blah";

And for a3 you may do the following:

a3[0] = &"hmm";
a3[1] = &"blah";

For a1 you will have to use strcpy() (better yet strncpy()) even when assigning string literals. The reason is that a2, and a3 are arrays of pointers and you can make their elements (i.e. pointers) point to any storage, whereas a1 is an array of 'array of chars' and so each element is an array that "owns" its own storage (which means it gets destroyed when it goes out of scope) - you can only copy stuff into its storage.

This also brings us to the disadvantage of using a2 and a3 - since they point to static storage (where string literals are stored) the contents of which cannot be reliably changed (viz. undefined behavior), if you want to assign non-string literals to the elements of a2 or a3 - you will first have to dynamically allocate enough memory and then have their elements point to this memory, and then copy the characters into it - and then you have to be sure to deallocate the memory when done.

Bah - I miss C++ already ;)

p.s. Let me know if you need examples.

Typing brew install cmake as you did installs cmake. Now you can type cmake and use it.

If typing cmake doesn’t work make sure /usr/local/bin is your PATH. You can see it with echo $PATH. If you don’t see /usr/local/bin in it add the following to your ~/.bashrc:

export PATH="/usr/local/bin:$PATH"

Then reload your shell session and try again.

(all the above assumes Homebrew is installed in its default location, /usr/local. If not you’ll have to replace /usr/local with $(brew --prefix) in the export line)

This is a nice way to do it:

Double d = 0.5;
float f = d.floatValue();

if you have d as a primitive type just add one line:

double d = 0.5;
Double D = Double.valueOf(d);
float f = D.floatValue();

I've had a lot of issues with a lot of answers on the net. Most work for most things, but there's always a corner case that breaks each one.
Maybe it doesn't work if it's got quotes, maybe it breaks if it doesn't have quotes, syntax error if the var has a space, some will only work on parameters (as opposed to environment variables), other techniques allow an empty set of quotes to pass as 'defined', and some trickier ones won't let you chain an else afterward.

Here's a solution I'm happy with, please let me know if you find a corner case it won't work for.

:ifSet
if "%~1"=="" (Exit /B 1) else (Exit /B 0)

Having that subroutine either in a your script, or in it's own .bat, should work.
So if you wanted to write (in pseudo):

if (var)
then something
else somethingElse

You can write:

(Call :ifSet %var% && (
    Echo something
)) || (
    Echo something else
)

It worked for all my tests:

(Call :ifSet && ECHO y) || ECHO n
(Call :ifSet a && ECHO y) || ECHO n
(Call :ifSet "" && ECHO y) || ECHO n
(Call :ifSet "a" && ECHO y) || ECHO n
(Call :ifSet "a a" && ECHO y) || ECHO n

Echo'd n, y, n, y, y

More examples:

• Wanna just check if? Call :ifSet %var% && Echo set
• Just if not (only the else)? Call :ifSet %var% || Echo set
• Checking a passed argument; works fine. Call :ifSet %1 && Echo set
• Didn't want to clog up your scripts/dupe code, so you put it in it's own ifSet.bat? No problem: ((Call ifSet.bat %var%) && Echo set) || (Echo not set)

You can use a case in this case, to separate versions one example is using FACT os (which returns the version etc of your system... the command facter will return the details:

root@sytem# facter -p os
{"name"=>"CentOS", "family"=>"RedHat", "release"=>{"major"=>"7", "minor"=>"0", "full"=>"7.0.1406"}}

#we capture release hash
$curr_os = $os['release']

case $curr_os['major'] {
  '7': { .... something }
  *: {something}
}

That is an fast example, Might have typos, or not exactly working. But using system facts you can see what happens.

The OS fact provides you 3 main variables: name, family, release... Under release you have a small dictionary with more information about your os! combining these you can create cases to meet your targets.

Using the base package:

df <- data.frame(days = c(88, 11, 2, 5, 22, 1, 222, 2), name = c("Lynn", "Tom", "Chris", "Lisa", "Kyla", "Tom", "Lynn", "Lynn"))

# Three lines
target <- c("Tom", "Lynn")
index <- df$name %in% target
df[index, ]

# One line
df[df$name %in% c("Tom", "Lynn"), ] 

Output:

  days name
1   88 Lynn
2   11  Tom
6    1  Tom
7  222 Lynn
8    2 Lynn

Using sqldf:

library(sqldf)
# Two alternatives:
sqldf('SELECT *
      FROM df 
      WHERE name = "Tom" OR name = "Lynn"')
sqldf('SELECT *
      FROM df 
      WHERE name IN ("Tom", "Lynn")')

So my question is: Is there a way to tell the compiler that a long long int is the also a int64_t, just like long int is?

This is a good question or problem, but I suspect the answer is NO.

Also, a long int may not be a long long int.

# if __WORDSIZE == 64
typedef long int  int64_t;
# else
__extension__
typedef long long int  int64_t;
# endif

I believe this is libc. I suspect you want to go deeper.

In both 32-bit compile with GCC (and with 32- and 64-bit MSVC), the output of the program will be:

int:           0
int64_t:       1
long int:      0
long long int: 1

32-bit Linux uses the ILP32 data model. Integers, longs and pointers are 32-bit. The 64-bit type is a long long.

Microsoft documents the ranges at Data Type Ranges. The say the long long is equivalent to __int64.

However, the program resulting from a 64-bit GCC compile will output:

int:           0
int64_t:       1
long int:      1
long long int: 0

64-bit Linux uses the LP64 data model. Longs are 64-bit and long long are 64-bit. As with 32-bit, Microsoft documents the ranges at Data Type Ranges and long long is still __int64.

There's a ILP64 data model where everything is 64-bit. You have to do some extra work to get a definition for your word32 type. Also see papers like 64-Bit Programming Models: Why LP64?

But this is horribly hackish and does not scale well (actual functions of substance, uint64_t, etc)...

Yeah, it gets even better. GCC mixes and matches declarations that are supposed to take 64 bit types, so its easy to get into trouble even though you follow a particular data model. For example, the following causes a compile error and tells you to use -fpermissive:

#if __LP64__
typedef unsigned long word64;
#else
typedef unsigned long long word64;
#endif

// intel definition of rdrand64_step (http://software.intel.com/en-us/node/523864)
// extern int _rdrand64_step(unsigned __int64 *random_val);

// Try it:
word64 val;
int res = rdrand64_step(&val);

It results in:

error: invalid conversion from `word64* {aka long unsigned int*}' to `long long unsigned int*'

So, ignore LP64 and change it to:

typedef unsigned long long word64;

Then, wander over to a 64-bit ARM IoT gadget that defines LP64 and use NEON:

error: invalid conversion from `word64* {aka long long unsigned int*}' to `uint64_t*'

There is no Pair in the standard framework, but the Apache Commons Lang, which comes quite close to “standard”, has a Pair.

There are a few differences between Temporary Tables (#tmp) and Table Variables (@tmp), although using tempdb isn't one of them, as spelt out in the MSDN link below.

As a rule of thumb, for small to medium volumes of data and simple usage scenarios you should use table variables. (This is an overly broad guideline with of course lots of exceptions - see below and following articles.)

Some points to consider when choosing between them:

• Temporary Tables are real tables so you can do things like CREATE INDEXes, etc. If you have large amounts of data for which accessing by index will be faster then temporary tables are a good option.

• Table variables can have indexes by using PRIMARY KEY or UNIQUE constraints. (If you want a non-unique index just include the primary key column as the last column in the unique constraint. If you don't have a unique column, you can use an identity column.) SQL 2014 has non-unique indexes too.

• Table variables don't participate in transactions and SELECTs are implicitly with NOLOCK. The transaction behaviour can be very helpful, for instance if you want to ROLLBACK midway through a procedure then table variables populated during that transaction will still be populated!

• Temp tables might result in stored procedures being recompiled, perhaps often. Table variables will not.

• You can create a temp table using SELECT INTO, which can be quicker to write (good for ad-hoc querying) and may allow you to deal with changing datatypes over time, since you don't need to define your temp table structure upfront.

• You can pass table variables back from functions, enabling you to encapsulate and reuse logic much easier (eg make a function to split a string into a table of values on some arbitrary delimiter).

• Using Table Variables within user-defined functions enables those functions to be used more widely (see CREATE FUNCTION documentation for details). If you're writing a function you should use table variables over temp tables unless there's a compelling need otherwise.

• Both table variables and temp tables are stored in tempdb. But table variables (since 2005) default to the collation of the current database versus temp tables which take the default collation of tempdb (ref). This means you should be aware of collation issues if using temp tables and your db collation is different to tempdb's, causing problems if you want to compare data in the temp table with data in your database.

• Global Temp Tables (##tmp) are another type of temp table available to all sessions and users.

Reason of the error: Package name left blank while creating a class. This make use of default package. Thus causes this error.

Quick fix:

1. Create a package eg. helloWorld inside the src folder.
2. Move helloWorld.java file in that package. Just drag and drop on the package. Error should disappear.

Explanation:

• My Eclipse version: 2020-09 (4.17.0)
• My Java version: Java 15, 2020-09-15

Latest version of Eclipse required java11 or above. The module feature is introduced in java9 and onward. It was proposed in 2005 for Java7 but later suspended. Java is object oriented based. And module is the moduler approach which can be seen in language like C. It was harder to implement it, due to which it took long time for the release. Source: Understanding Java 9 Modules

When you create a new project in Eclipse then by default module feature is selected. And in Eclipse-2020-09-R, a pop-up appears which ask for creation of module-info.java file. If you select don't create then module-info.java will not create and your project will free from this issue.

Best practice is while crating project, after giving project name. Click on next button instead of finish. On next page at the bottom it ask for creation of module-info.java file. Select or deselect as per need.

If selected: (by default) click on finish button and give name for module. Now while creating a class don't forget to give package name. Whenever you create a class just give package name. Any name, just don't left it blank.

If deselect: No issue

Depends. If you know you're going to need both the key and the value of every entry, then go through the entrySet. If you just need the values, then there's the values() method. And if you just need the keys, then use keyset().

A bad practice would be to iterate through all of the keys, and then within the loop, always do map.get(key) to get the value. If you're doing that, then the first option I wrote is for you.

u should add a theme to ur all activities (u should add theme for all application in ur <application> in ur manifest) but if u have set different theme to ur activity u can use :

 android:theme="@style/Theme.AppCompat"

or each kind of AppCompat theme!

Yes, but what does grouping by more two columns mean? Well, it's the same as grouping by each unique pair per row. The order you list the columns changes the way the rows are sorted.

In your example, you would write

GROUP BY fV.tier_id, f.form_template_id

Meanwhile, the code

GROUP BY f.form_template_id, fV.tier_id

would give similar results, but sorted differently.

In CSS, for the font-weight property, the value: normal defaults to the numeric value 400, and bold to 700.

If you want to specify other weights, you need to give the number value. That number value needs to be supported for the font family that you are using.

For example you would define semi-bold like this:

font-weight: 600;

Here an JSFiddle using 'Open Sans' font family, loaded with the above weights.

As for "phone numbers" you should really consider the difference between a "subscriber number" and a "dialling number" and the possible formatting options of them.

A subscriber number is generally defined in the national numbering plans. The question itself shows a relation to a national view by mentioning "area code" which a lot of nations don't have. ITU has assembled an overview of the world's numbering plans publishing recommendation E.164 where the national number was found to have a maximum of 12 digits. With international direct distance calling (DDD) defined by a country code of 1 to 3 digits they added that up to 15 digits ... without formatting.

The dialling number is a different thing as there are network elements that can interpret exta values in a phone number. You may think of an answering machine and a number code that sets the call diversion parameters. As it may contain another subscriber number it must be obviously longer than its base value. RFC 4715 has set aside 20 bcd-encoded bytes for "subaddressing".

If you turn to the technical limitation then it gets even more as the subscriber number has a technical limit in the 10 bcd-encoded bytes in the 3GPP standards (like GSM) and ISDN standards (like DSS1). They have a seperate TON/NPI byte for the prefix (type of number / number plan indicator) which E.164 recommends to be written with a "+" but many number plans define it with up to 4 numbers to be dialled.

So if you want to be future proof (and many software systems run unexpectingly for a few decades) you would need to consider 24 digits for a subscriber number and 64 digits for a dialling number as the limit ... without formatting. Adding formatting may add roughly an extra character for every digit. So as a final thought it may not be a good idea to limit the phone number in the database in any way and leave shorter limits to the UX designers.

You have to increase client_max_body_size in nginx.conf file. This is the basic step. But if your backend laravel then you have to do some changes in the php.ini file as well. It depends on your backend. Below I mentioned file location and condition name.

sudo vim /etc/nginx/nginx.conf.

After open the file adds this into HTTP section.

client_max_body_size 100M;

According to http://www.techotopia.com/index.php/Ruby_String_Concatenation_and_Comparison

Doing either

mystring == yourstring

or

mystring.eql? yourstring

Are equivalent.

1) The result of repr('foo') is the string 'foo'. In your Python shell, the result of the expression is expressed as a representation too, so you're essentially seeing repr(repr('foo')).

2) eval calculates the result of an expression. The result is always a value (such as a number, a string, or an object). Multiple variables can refer to the same value, as in:

x = 'foo'
y = x

x and y now refer to the same value.

3) I have no idea what you meant here. Can you post an example, and what you'd like to see?

with paging you need to do some calculation

int index = Convert.ToInt32(e.CommandArgument) % GridView1.PageSize;

I've found that you can use any subset condition for a given column by wrapping it in []. For instance, you have a df with columns ['Product','Time', 'Year', 'Color']

And let's say you want to include products made before 2014. You could write,

df[df['Year'] < 2014]

To return all the rows where this is the case. You can add different conditions.

df[df['Year'] < 2014][df['Color' == 'Red']

Then just choose the columns you want as directed above. For instance, the product color and key for the df above,

df[df['Year'] < 2014][df['Color'] == 'Red'][['Product','Color']]

If you have the files written under .gitignore, remove the files and run git pull again. That helped me out.

I also banged my head around this problem for some time and wished to solve this in an elegant but quick way.

Here are my 20 cents:

• The answer using labels as mentioned here won't work if you are updating labels. But would work if you always add labels. More details here.

• The answer mentioned here is the most elegant way to do this quickly according to me but had the problem of handling deletes. I am adding on to this answer:

Solution

I am doing this in one of the Kubernetes Operator where only a single task is performed in one reconcilation loop.

• Compute the hash of the config map data. Say it comes as v2.
• Create ConfigMap cm-v2 having labels: version: v2 and product: prime if it does not exist and RETURN. If it exists GO BELOW.
• Find all the Deployments which have the label product: prime but do not have version: v2, If such deployments are found, DELETE them and RETURN. ELSE GO BELOW.
• Delete all ConfigMap which has the label product: prime but does not have version: v2 ELSE GO BELOW.
• Create Deployment deployment-v2 with labels product: prime and version: v2 and having config map attached as cm-v2 and RETURN, ELSE Do nothing.

That's it! It looks long, but this could be the fastest implementation and is in principle with treating infrastructure as Cattle (immutability).

Also, the above solution works when your Kubernetes Deployment has Recreate update strategy. Logic may require little tweaks for other scenarios.

I can confirm that mp4 just will not work in the video tag. No matter how much you try to mess with the type tag and the codec and the mime types from the server.

Crazy, because for the same exact video, on the same test page, the old embed tag for an mp4 works just fine in firefox. I spent all yesterday messing with this. Firefox is like IE all of a sudden, hours and hours of time, not billable. Yay.

Speaking of IE, it fails FAR MORE gracefully on this. When it can't match up the format it falls to the content between the tags, so it is possible to just put video around object around embed and everything works great. Firefox, nope, despite failing, it puts up the poster image (greyed out so that isn't even useful as a fallback) with an error message smack in the middle. So now the options are put in browser recognition code (meaning we've gained nothing on embedding videos in the last ten years) or ditch html5.

I found @Piyush's answer helpful, and just to add to it, if you programatically create a select, then there is an important way to get this behavior that may not be obvious. Let's say you have a function and you create a new select:

var changeitem = function (sel) {
  console.log(sel.selectedIndex);
}
var newSelect = document.createElement('select');
newSelect.id = 'newselect';

The normal behavior may be to say

newSelect.onchange = changeitem;

But this does not really allow you to specify that argument passed in, so instead you may do this:

newSelect.setAttribute('onchange', 'changeitem(this)');

And you are able to set the parameter. If you do it the first way, then the argument you'll get to your onchange function will be browser dependent. The second way seems to work cross-browser just fine.

If you are using angular ui-router this will be the best solution.

$scope.myLoadingFunction = function() {
    $state.reload();
};

C++0x FAQ by BS

TL;DR: add the parameter cursorclass=MySQLdb.cursors.DictCursor at the end of your MySQLdb.connect.

I had a working code and the DB moved, I had to change the host/user/pass. After this change, my code stopped working and I started getting this error. Upon closer inspection, I copy-pasted the connection string on a place that had an extra directive. The old code read like:

 conn = MySQLdb.connect(host="oldhost",
                        user="olduser",
                        passwd="oldpass",
                        db="olddb", 
                        cursorclass=MySQLdb.cursors.DictCursor)

Which was replaced by:

 conn = MySQLdb.connect(host="newhost",
                        user="newuser",
                        passwd="newpass",
                        db="newdb")

The parameter cursorclass=MySQLdb.cursors.DictCursor at the end was making python allow me to access the rows using the column names as index. But the poor copy-paste eliminated that, yielding the error.

So, as an alternative to the solutions already presented, you can also add this parameter and access the rows in the way you originally wanted. ^_^ I hope this helps others.

The best way to do this with modern browsers would be to make use of Viewport-percentage Lengths, falling back to regular percentage lengths for browsers which do not support those units.

Viewport-percentage lengths are based upon the length of the viewport itself. The two units we will use here are vh (viewport height) and vw (viewport width). 100vh is equal to 100% of the height of the viewport, and 100vw is equal to 100% of the width of the viewport.

Assuming the following HTML:

<body>
    <div></div>
</body>

You can use the following:

html, body, div {
    /* Height and width fallback for older browsers. */
    height: 100%;
    width: 100%;

    /* Set the height to match that of the viewport. */
    height: 100vh;

    /* Set the width to match that of the viewport. */
    width: 100vw;

    /* Remove any browser-default margins. */
    margin: 0;
}

Here is a JSFiddle demo which shows the div element filling both the height and width of the result frame. If you resize the result frame, the div element resizes accordingly.

Took me a while to aggregate an actual solution, but here's how to get rid of this compile error.

1. Open IntelliJ preferences.

2. Search for "compiler" (or something like "compi").

3. Scroll down to Maven -->java compiler. In the right panel will be a list of modules and their associated java compile version "target bytecode version."

4. Select a version >1.5. You may need to upgrade your jdk if one is not available.

we had to do this so often that I made what I called a DelegateParameter class

using System;
using System.Collections.Generic;
using System.Text;
using System.Web.UI.WebControls;
using System.Reflection;

namespace MyControls
{
    public delegate object EvaluateParameterEventHandler(object sender, EventArgs e);

    public class DelegateParameter : Parameter
    {
        private System.Web.UI.Control _parent;
        public System.Web.UI.Control Parent
        {
            get { return _parent; }
            set { _parent = value; }
        }

        private event EvaluateParameterEventHandler _evaluateParameter;
        public event EvaluateParameterEventHandler EvaluateParameter
        {
            add { _evaluateParameter += value; }
            remove { _evaluateParameter -= value; }
        }

        protected override object Evaluate(System.Web.HttpContext context, System.Web.UI.Control control)
        {
            return _evaluateParameter(this, EventArgs.Empty);
        }
    }
}

put this class either in your app_code (remove the namespace if you put it there) or in your custom control assembly. After the control is registered in the web.config you should be able to do this

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:itematConnectionString %>"
    SelectCommand = "SELECT items.name, items.id FROM items INNER JOIN users_items ON items.id = users_items.id WHERE (users_items.user_id = @userId) ORDER BY users_items.date DESC">
    <SelectParameters>
    <asp:DelegateParameter Name="userId"  DbType="Guid" OnEvaluate="GetUserID" />
    </SelectParameters>
</asp:SqlDataSource>

then in the code behind you implement the GetUserID anyway you like.

protected object GetUserID(object sender, EventArgs e)
{
  return userId;
}

I don't know about that specific SharePoint web service, but you can decorate a page method or a web service with <WebMethod()> (in VB.NET) to ensure that it serializes to JSON. You can probably just wrap the method that webservice.asmx uses internally, in your own web service.

Dave Ward has a nice walkthrough on this.

I found that the best way it to add always the +trace option:

dig SOA +trace stackoverflow.com

It works also with recursive CNAME hosted in different provider. +trace trace imply +norecurse so the result is just for the domain you specify.

Can you try this, readfile need the full file path.

        $filename='/pdf/jobs/pdffile.pdf';            
        $url_download = BASE_URL . RELATIVE_PATH . $filename;            

        //header("Content-type:application/pdf");   
        header("Content-type: application/octet-stream");                       
        header("Content-Disposition:inline;filename='".basename($filename)."'");            
        header('Content-Length: ' . filesize($filename));
        header("Cache-control: private"); //use this to open files directly                     
        readfile($filename);

I did as per sid saying my env after updating is

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=<mygmailaddress>
MAIL_PASSWORD=<gmailpassword>
MAIL_ENCRYPTION=tls

this did work without 2 step verification. with 2 step verification enabled it did not work for me.

Something like this?

div {_x000D_
  border: 1px solid #202020;_x000D_
  margin-top: 25px;_x000D_
  margin-left: 25px;_x000D_
  width: 158px;_x000D_
  height: 158px;_x000D_
  padding-top: 25px;_x000D_
  -webkit-box-shadow: 0px -4px 3px rgba(50, 50, 50, 0.75);_x000D_
  -moz-box-shadow: 0px -4px 3px rgba(50, 50, 50, 0.75);_x000D_
  box-shadow: 0px -4px 3px rgba(50, 50, 50, 0.75);_x000D_
}

<div></div>

You can use [(ngModel)], but you'll need to update your value to [value] otherwise the value is evaluating as a string. It would look like this:

<label>This rule is true if:</label>
<label class="form-check-inline">
    <input class="form-check-input" type="radio" name="mode" [value]="true" [(ngModel)]="rule.mode">
</label>
<label class="form-check-inline">
    <input class="form-check-input" type="radio" name="mode" [value]="false" [(ngModel)]="rule.mode">
</label>

If rule.mode is true, then that radio is selected. If it's false, then the other.

The difference really comes down to the value. value="true" really evaluates to the string 'true', whereas [value]="true" evaluates to the boolean true.

Now you can see both the pseudo-class rules and force them on elements.

To see the rules like :hover in the Styles pane click the small :hov text in the top right.

To force an element into :hover state, right click it and select :hover.

Why don't you just save/serve the CSS file as UTF-8?

nav a:hover:after {
    content: "?";
}

If that's not good enough, and you want to keep it all-ASCII:

nav a:hover:after {
    content: "\2193";
}

The general format for a Unicode character inside a string is \000000 to \FFFFFF – a backslash followed by six hexadecimal digits. You can leave out leading 0 digits when the Unicode character is the last character in the string or when you add a space after the Unicode character. See the spec below for full details.

Relevant part of the CSS2 spec:

Third, backslash escapes allow authors to refer to characters they cannot easily put in a document. In this case, the backslash is followed by at most six hexadecimal digits (0..9A..F), which stand for the ISO 10646 ([ISO10646]) character with that number, which must not be zero. (It is undefined in CSS 2.1 what happens if a style sheet does contain a character with Unicode codepoint zero.) If a character in the range [0-9a-fA-F] follows the hexadecimal number, the end of the number needs to be made clear. There are two ways to do that:

1. with a space (or other white space character): "\26 B" ("&B"). In this case, user agents should treat a "CR/LF" pair (U+000D/U+000A) as a single white space character.
2. by providing exactly 6 hexadecimal digits: "\000026B" ("&B")

In fact, these two methods may be combined. Only one white space character is ignored after a hexadecimal escape. Note that this means that a "real" space after the escape sequence must be doubled.

If the number is outside the range allowed by Unicode (e.g., "\110000" is above the maximum 10FFFF allowed in current Unicode), the UA may replace the escape with the "replacement character" (U+FFFD). If the character is to be displayed, the UA should show a visible symbol, such as a "missing character" glyph (cf. 15.2, point 5).

• Note: Backslash escapes are always considered to be part of an identifier or a string (i.e., "\7B" is not punctuation, even though "{" is, and "\32" is allowed at the start of a class name, even though "2" is not).
  The identifier "te\st" is exactly the same identifier as "test".

I want to add a little bit of improvement from an almost excellent answer from user @thyago stall above. In Python, we can do one line swapping. The selection_sort below also has been fixed by just swapping the current element with the minimum element at the right side.

In insertion sort we will run the outer loop from the second element and do an inner loop on the left side of the current element, shifting the smaller elements to the left.

def insertion_sort(arr):
    i = 1
    while i < len(arr):
        for j in range(i):
            if arr[i] < arr[j]:
                arr[i], arr[j] = arr[j], arr[i]
    i += 1

In selection sort, we also run the outer loop but instead of starting from the second element, we start from the first element. Then inner loop will loop the current + i element to the end of array to find the minimum element and we will swapped with the current index.

def selection_sort(arr):
    i = 0
    while i < len(arr):
        min_idx = i
        for j in range(i + 1, len(arr)):
            if arr[min_idx] > arr[j]:
                min_idx = j
        arr[i], arr[min_idx] = arr[min_idx], arr[i]
    i += 1

I'm always skeptical about the Next Big Thing. Lots of times the Next Big Thing is pure accident of history, being there in the right place at the right time no matter whether the technology is good or not. Examples: C++, Tcl/Tk, Perl. All flawed technologies, all wildly successful because they were perceived either to solve the problems of the day or to be nearly identical to entrenched standards, or both. Functional programming may indeed be great, but that doesn't mean it will be adopted.

But I can tell you why people are excited about functional programming: many, many programmers have had a kind of "conversion experience" in which they discover that using a functional language makes them twice as productive (or maybe ten times as productive) while producing code that is more resilient to change and has fewer bugs. These people think of functional programming as a secret weapon; a good example of this mindset is Paul Graham's Beating the Averages. Oh, and his application? E-commerce web apps.

Since early 2006 there has also been some buzz about functional programming and parallelism. Since people like Simon Peyton Jones have been worrying about parallelism off and on since at least 1984, I'm not holding my breath until functional languages solve the multicore problem. But it does explain some of the additional buzz right about now.

In general, American universities are doing a poor job teaching functional programming. There's a strong core of support for teaching intro programming using Scheme, and Haskell also enjoys some support there, but there's very little in the way of teaching advanced technique for functional programmer. I've taught such a course at Harvard and will do so again this spring at Tufts. Benjamin Pierce has taught such a course at Penn. I don't know if Paul Hudak has done anything at Yale. The European universities are doing a much better job; for example, functional programming is emphasized in important places in Denmark, the Netherlands, Sweden, and the UK. I have less of a sense of what's happening in Australasia.

You can probably just use the true command:

if [ "$a" -ge 10 ]; then
    true
elif [ "$a" -le 5 ]; then
    echo "1"
else
    echo "2"
fi

An alternative, in your example case (but not necessarily everywhere) is to re-order your if/else:

if [ "$a" -le 5 ]; then
    echo "1"
elif [ "$a" -lt 10 ]; then
    echo "2"
fi

I use: /drawable/circulo.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval">
    <solid android:angle="270"
        android:color="@color/your_color" />

</shape>

And then I use it in my TextView as:

android:background="@drawable/circulo"

no need to complicated it.

I think the problem is here:

[contains(text()='Some text')]

To break this down,

1. The [] are a conditional that operates on each individual node in that node set -- each span node in your case. It matches if any of the individual nodes it operates on match the conditions inside the brackets.
2. text() is a selector that matches all of the text nodes that are children of the context node -- it returns a node set.
3. contains is a function that operates on a string. If it is passed a node set, the node set is converted into a string by returning the string-value of the node in the node-set that is first in document order.

You should try to change this to

[text()[contains(.,'Some text')]]

1. The outer [] are a conditional that operates on each individual node in that node set text() is a selector that matches all of the text nodes that are children of the context node -- it returns a node set.

2. The inner [] are a conditional that operates on each node in that node set.

3. contains is a function that operates on a string. Here it is passed an individual text node (.).

This works for me:

 yarn add --dev tsconfig-paths

 ts-node -r tsconfig-paths/register <your-index-file>.ts

This loads all paths in tsconfig.json. A sample tsconfig.json:

{
    "compilerOptions": {
        {…}
        "baseUrl": "./src",
        "paths": {
            "assets/*": [ "assets/*" ],
            "styles/*": [ "styles/*" ]
        }
    },
}

Make sure you have both baseUrl and paths for this to work

And then you can import like :

import {AlarmIcon} from 'assets/icons'

you can do that

var filteredFileList = fileList.Where(fl => filterList.Contains(fl.ToString()));

How to change max_connections

You can change max_connections while MySQL is running via SET:

mysql> SET GLOBAL max_connections = 5000;
Query OK, 0 rows affected (0.00 sec)

mysql> SHOW VARIABLES LIKE "max_connections";
+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 5000  |
+-----------------+-------+
1 row in set (0.00 sec)

To OP

timeout related

I had never seen your error message before, so I googled. probably, you are using Connector/Net. Connector/Net Manual says there is max connection pool size. (default is 100) see table 22.21.

I suggest that you increase this value to 100k or disable connection pooling Pooling=false

UPDATED

he has two questions.

Q1 - what happens if I disable pooling Slow down making DB connection. connection pooling is a mechanism that use already made DB connection. cost of Making new connection is high. http://en.wikipedia.org/wiki/Connection_pool

Q2 - Can the value of pooling be increased or the maximum is 100?

you can increase but I'm sure what is MAX value, maybe max_connections in my.cnf

My suggestion is that do not turn off Pooling, increase value by 100 until there is no connection error.

If you have Stress Test tool like JMeter you can test youself.

The current accepted answer by crack is deprecated in Symfony 2.3 and will be removed by 3.0. It should be moved to the constructor:

public function __construct($environment, $debug) {
    date_default_timezone_set('Europe/Warsaw');
    parent::__construct($environment, $debug);
}

I feel we had a related discussion earlier: How to upload preview image before upload through JavaScript

I use an enum with no instances

public enum MyUtils { 
    ; // no instances
    // class is final and the constructor is private

    public static int myUtilityMethod(int x) {
        return x * x;
    }
}

you can call this using

int y = MyUtils.myUtilityMethod(5); // returns 25.

Long string: Just use echo($var); instead of dump($var);.

I wrote two programs:

int main(){return 0;}

and

#include <stdlib.h>
int main(){exit(0)}

After executing gcc -S -O1. Here what I found watching at assembly (only important parts):

main:
    movl    $0, %eax    /* setting return value */
    ret                 /* return from main */

and

main:
    subq    $8, %rsp    /* reserving some space */
    movl    $0, %edi    /* setting return value */
    call    exit        /* calling exit function */
                        /* magic and machine specific wizardry after this call */

So my conclusion is: use return when you can, and exit() when you need.

If You want nice format like: 0:00:00 use str_pad() as @Gardner.

I... don't think so. You can redirect the subdomain (such as blah.something.com) to point to something.com:25566, but I don't think you can actually set up the subdomain to be on a different port like that. I could be wrong, but it'd probably be easier to use a simple .htaccess or something to check %{HTTP_HOST} and redirect according to the subdomain.

You can use the below C# Method to generate the insert scripts using Excel sheet just you need import OfficeOpenXml Package from NuGet Package Manager before executing the method.

public string GenerateSQLInsertScripts() {

        var outputQuery = new StringBuilder();

        if (file != null)
        {
            var filePath = @"D:\FileName.xsls";

            using (OfficeOpenXml.ExcelPackage xlPackage = new OfficeOpenXml.ExcelPackage(new FileInfo(filePath)))
            {
                var myWorksheet = xlPackage.Workbook.Worksheets.First(); //select the first sheet here
                var totalRows = myWorksheet.Dimension.End.Row;
                var totalColumns = myWorksheet.Dimension.End.Column;

                var columns = new StringBuilder(); //this is your columns

                var columnRows = myWorksheet.Cells[1, 1, 1, totalColumns].Select(c => c.Value == null ? string.Empty : c.Value.ToString());

                columns.Append("INSERT INTO["+ tableName +"] (");
                foreach (var colrow in columnRows)
                {
                    columns.Append("[");
                    columns.Append(colrow);
                    columns.Append("]");
                    columns.Append(",");
                }
                columns.Length--;
                columns.Append(") VALUES (");
                for (int rowNum = 2; rowNum <= totalRows; rowNum++) //selet starting row here
                {
                    var dataRows = myWorksheet.Cells[rowNum, 1, rowNum, totalColumns].Select(c => c.Value == null ? string.Empty : c.Value.ToString());

                    var finalQuery = new StringBuilder(); 
                    finalQuery.Append(columns);

                    foreach (var dataRow in dataRows)
                    {
                        finalQuery.Append("'");
                        finalQuery.Append(dataRow);
                        finalQuery.Append("'");
                        finalQuery.Append(",");
                    }
                    finalQuery.Length--;

                    finalQuery.Append(");");

                    outputQuery.Append(finalQuery);

                  }

            }
        }

return outputQuery.ToString();}

This suppresses warnings.

There is a racecondition between the last command ($_) and last error ( $?) variables. If you try to store one of them in an own variable, both encountered new values already because of the set command. Actually, last command hasn't got any value at all in this case.

Here is what i did to store (nearly) both informations in own variables, so my bash script can determine if there was any error AND setting the title with the last run command:

   # This construct is needed, because of a racecondition when trying to obtain
   # both of last command and error. With this the information of last error is
   # implied by the corresponding case while command is retrieved.

   if   [[ "${?}" == 0 && "${_}" != "" ]] ; then
    # Last command MUST be retrieved first.
      LASTCOMMAND="${_}" ;
      RETURNSTATUS='?' ;
   elif [[ "${?}" == 0 && "${_}" == "" ]] ; then
      LASTCOMMAND='unknown' ;
      RETURNSTATUS='?' ;
   elif [[ "${?}" != 0 && "${_}" != "" ]] ; then
    # Last command MUST be retrieved first.
      LASTCOMMAND="${_}" ;
      RETURNSTATUS='?' ;
      # Fixme: "$?" not changing state until command executed.
   elif [[ "${?}" != 0 && "${_}" == "" ]] ; then
      LASTCOMMAND='unknown' ;
      RETURNSTATUS='?' ;
      # Fixme: "$?" not changing state until command executed.
   fi

This script will retain the information, if an error occured and will obtain the last run command. Because of the racecondition i can not store the actual value. Besides, most commands actually don't even care for error noumbers, they just return something different from '0'. You'll notice that, if you use the errono extention of bash.

It should be possible with something like a "intern" script for bash, like in bash extention, but i'm not familiar with something like that and it wouldn't be compatible as well.

CORRECTION

I didn't think, that it was possible to retrieve both variables at the same time. Although i like the style of the code, i assumed it would be interpreted as two commands. This was wrong, so my answer devides down to:

   # Because of a racecondition, both MUST be retrieved at the same time.
   declare RETURNSTATUS="${?}" LASTCOMMAND="${_}" ;

   if [[ "${RETURNSTATUS}" == 0 ]] ; then
      declare RETURNSYMBOL='?' ;
   else
      declare RETURNSYMBOL='?' ;
   fi

Although my post might not get any positive rating, i solved my problem myself, finally. And this seems appropriate regarding the intial post. :)

Check if you're referencing jquery.js BEFORE bootstrap.js and bootstrap.js is loaded only once. That fixed the same error for me:

<script type="text/javascript" src="js/jquery-1.8.0.js"></script>
<script type="text/javascript" src="js/bootstrap.min.js"></script>

Data validation drop down

There is a list option in Data validation. If this is combined with a VLOOKUP formula you would be able to convert the selected value into a number.

The steps in Excel 2010 are:

• Create your list with matching values.
• On the Data tab choose Data Validation
• The Data validation form will be displayed
• Set the Allow dropdown to List
• Set the Source range to the first part of your list
• Click on OK (User messages can be added if required)

In a cell enter a formula like this

=VLOOKUP(A2,$D$3:$E$5,2,FALSE)

which will return the matching value from the second part of your list.

Form control drop down

Alternatively, Form controls can be placed on a worksheet. They can be linked to a range and return the position number of the selected value to a specific cell.

The steps in Excel 2010 are:

• Create your list of data in a worksheet
• Click on the Developer tab and dropdown on the Insert option
• In the Form section choose Combo box or List box
• Use the mouse to draw the box on the worksheet
• Right click on the box and select Format control
• The Format control form will be displayed
• Click on the Control tab
• Set the Input range to your list of data
• Set the Cell link range to the cell where you want the number of the selected item to appear
• Click on OK

When you do return Json(...) you are specifically telling MVC not to use a view, and to serve serialized JSON data. Your browser opens a download dialog because it doesn't know what to do with this data.

If you instead want to return a view, just do return View(...) like you normally would:

var dictionary = listLocation.ToDictionary(x => x.label, x => x.value);
return View(new { Values = listLocation });

Then in your view, simply encode your data as JSON and assign it to a JavaScript variable:

<script>
    var values = @Html.Raw(Json.Encode(Model.Values));
</script>

EDIT

Here is a bit more complete sample. Since I don't have enough context from you, this sample will assume a controller Foo, an action Bar, and a view model FooBarModel. Additionally, the list of locations is hardcoded:

Controllers/FooController.cs

public class FooController : Controller
{
    public ActionResult Bar()
    {
        var locations = new[]
        {
            new SelectListItem { Value = "US", Text = "United States" },
            new SelectListItem { Value = "CA", Text = "Canada" },
            new SelectListItem { Value = "MX", Text = "Mexico" },
        };

        var model = new FooBarModel
        {
            Locations = locations,
        };

        return View(model);
    }
}

Models/FooBarModel.cs

public class FooBarModel
{
    public IEnumerable<SelectListItem> Locations { get; set; }
}

Views/Foo/Bar.cshtml

@model MyApp.Models.FooBarModel

<script>
    var locations = @Html.Raw(Json.Encode(Model.Locations));
</script>

By the looks of your error message, it seems like you are mixing incompatible types (i.e. Ported_LI.Models.Locatio??n and MyApp.Models.Location) so, to recap, make sure the type sent from the controller action side match what is received from the view. For this sample in particular, new FooBarModel in the controller matches @model MyApp.Models.FooBarModel in the view.

Since office 2013 use this inbuilt function here.

If before office 2013

Function encodeURL(str As String)
Dim ScriptEngine As ScriptControl
Set ScriptEngine = New ScriptControl
ScriptEngine.Language = "JScript"

ScriptEngine.AddCode "function encode(str) {return encodeURIComponent(str);}"
Dim encoded As String


encoded = ScriptEngine.Run("encode", str)
encodeURL = encoded
End Function

Add Microsoft Script Control as reference and you are done.

Same as last post just complete function ..works!

The javax.naming package comprises the JNDI API. Since it's just an API, rather than an implementation, you need to tell it which implementation of JNDI to use. The implementations are typically specific to the server you're trying to talk to.

To specify an implementation, you pass in a Properties object when you construct the InitialContext. These properties specify the implementation to use, as well as the location of the server. The default InitialContext constructor is only useful when there are system properties present, but the properties are the same as if you passed them in manually.

As to which properties you need to set, that depends on your server. You need to hunt those settings down and plug them in.

If you are using modal use view dismiss.

[self dismissViewControllerAnimated:NO completion:nil];

Indeed, you can use the "create" method of Mongoose, it can contain an array of documents, see this example:

Candy.create({ candy: 'jelly bean' }, { candy: 'snickers' }, function (err, jellybean, snickers) {
});

The callback function contains the inserted documents. You do not always know how many items has to be inserted (fixed argument length like above) so you can loop through them:

var insertedDocs = [];
for (var i=1; i<arguments.length; ++i) {
    insertedDocs.push(arguments[i]);
}

Update: A better solution

A better solution would to use Candy.collection.insert() instead of Candy.create() - used in the example above - because it's faster (create() is calling Model.save() on each item so it's slower).

See the Mongo documentation for more information: http://docs.mongodb.org/manual/reference/method/db.collection.insert/

(thanks to arcseldon for pointing this out)

open Credential Manager -> look for your GIT devops profile -> click on it -> edit -> add user and password generated in DevOps and save.

Here is the alternative command:

gnuplot -p -e 'plot for [file in system("find . -name \\*.txt -depth 1")] file using 1:2 title file with lines'

This is an alternative solution, but one could argue it doesn't add enough value to make it worth it:

import com.google.common.collect.Iterables;
...
Iterator<String> iter = Iterables.cycle(list).iterator();
if(iter.hasNext()) {
    str = iter.next();
}

Calling hasNext() will reset the iterator cursor to the beginning if it's a the end.

Not perfect but close:

newcol<-sapply(rownames(t), function(rn){z[match(rn, rownames(z)), 5]})
cbind(data.frame(t), newcol)

To analyze a query you already have entered into the Query editor, you need to choose "Include Actual Execution Plan" (7th toggle button to the right of the "! Execute" button). After executing the query, you need to click on the "Execution Plan" tab in the results pane at the bottom (above the results of the query).

Something like

select *
  from foo
 where regexp_like( col1, '[^[:alpha:]]' ) ;

should work

SQL> create table foo( col1 varchar2(100) );

Table created.

SQL> insert into foo values( 'abc' );

1 row created.

SQL> insert into foo values( 'abc123' );

1 row created.

SQL> insert into foo values( 'def' );

1 row created.

SQL> select *
  2    from foo
  3   where regexp_like( col1, '[^[:alpha:]]' ) ;

COL1
--------------------------------------------------------------------------------
abc123

First create a file named gradle.properties in the following directory:

/home/<username>/.gradle/ (Linux)
/Users/<username>/.gradle/ (Mac)
C:\Users\<username>\.gradle (Windows)

Add this line to the file:

org.gradle.daemon=true
org.gradle.parallel=true

And check this options in Android Studio

I use talib.CORREL for autocorrelation like this, I suspect you could do the same with other packages:

def autocorrelate(x, period):

    # x is a deep indicator array 
    # period of sample and slices of comparison

    # oldest data (period of input array) may be nan; remove it
    x = x[-np.count_nonzero(~np.isnan(x)):]
    # subtract mean to normalize indicator
    x -= np.mean(x)
    # isolate the recent sample to be autocorrelated
    sample = x[-period:]
    # create slices of indicator data
    correls = []
    for n in range((len(x)-1), period, -1):
        alpha = period + n
        slices = (x[-alpha:])[:period]
        # compare each slice to the recent sample
        correls.append(ta.CORREL(slices, sample, period)[-1])
    # fill in zeros for sample overlap period of recent correlations    
    for n in range(period,0,-1):
        correls.append(0)
    # oldest data (autocorrelation period) will be nan; remove it
    correls = np.array(correls[-np.count_nonzero(~np.isnan(correls)):])      

    return correls

# CORRELATION OF BEST FIT
# the highest value correlation    
max_value = np.max(correls)
# index of the best correlation
max_index = np.argmax(correls)

If using Postgres, create sequence manually with name 'hibernate_sequence'. It will work.

Starting Python 3.8, a .prod function has been included to the math module in the standard library:

math.prod(iterable, *, start=1)

The method returns the product of a start value (default: 1) times an iterable of numbers:

import math
math.prod([1, 2, 3, 4, 5, 6])

>>> 720

If the iterable is empty, this will produce 1 (or the start value, if provided).

If you're fetching a single item only then, you need use select before your FirstOrDefault()/SingleOrDefault(). And you can use anonymous object of the required properties.

var name = dbContext.MyTable.Select(x => new { x.UserId, x.Name }).FirstOrDefault(x => x.UserId == 1)?.Name;

Above query will be converted to this:

Select Top (1) UserId, Name from MyTable where UserId = 1;

For multiple items you can simply chain Select after Where:

var names = dbContext.MyTable.Where(x => x.UserId > 10).Select(x => x.Name);

Use anonymous object inside Select if you need more than one properties.

I use Ext, so I ended up doing this:

var theForm = Ext.get("theform");
var inputButtons = Ext.DomQuery.jsSelect('input[type="submit"]', theForm.dom);
var inputButtonPressed = null;
for (var i = 0; i < inputButtons.length; i++) {
    Ext.fly(inputButtons[i]).on('click', function() {
        inputButtonPressed = this;
    }, inputButtons[i]);
}

and then when it was time submit I did

if (inputButtonPressed !== null) inputButtonPressed.click();
else theForm.dom.submit();

Wait, you say. This will loop if you're not careful. So, onSubmit must sometimes return true

// Notice I'm not using Ext here, because they can't stop the submit
theForm.dom.onsubmit = function () {
    if (gottaDoSomething) {
        // Do something asynchronous, call the two lines above when done.
        gottaDoSomething = false;
        return false;
    }
    return true;
}

Now suppose there is an action for redux as:

export function addTodo(text) {
  return {
    type: ADD_TODO,
    text
  }
}

When you do import it,

import {addTodo} from './actions';

class Greeting extends React.Component {

    handleOnClick = () => {
        this.props.onTodoClick(); // This prop acts as key to callback prop for mapDispatchToProps
    }

    render() {
        return <button onClick={this.handleOnClick}>Hello Redux</button>;
    }
}

const mapDispatchToProps = dispatch => {
    return {
      onTodoClick: () => { // handles onTodoClick prop's call here
        dispatch(addTodo())
      }
    }
}

export default connect(
    null,
    mapDispatchToProps
)(Greeting);

As function name says mapDispatchToProps(), map dispatch action to props(our component's props)

So prop onTodoClick is a key to mapDispatchToProps function which delegates furthere to dispatch action addTodo.

Also if you want to trim the code and bypass manual implementation, then you can do this,

import {addTodo} from './actions';
class Greeting extends React.Component {

    handleOnClick = () => {
        this.props.addTodo();
    }

    render() {
        return <button onClick={this.handleOnClick}>Hello Redux</button>;
    }
}

export default connect(
    null,
    {addTodo}
)(Greeting);

Which exactly means

const mapDispatchToProps = dispatch => {
    return {
      addTodo: () => { 
        dispatch(addTodo())
      }
    }
}

for "THIS IS" not to be bold - add <span></span> around the text

<h1>><span>THIS IS</span> A HEADLINE</h1>

and in style

h1 span{font-weight:normal}

Yes,that is called short-circuiting.

Please take a look at this wikipedia page on short-circuiting

I was getting this error on a Spring Boot application where a @RestController ApplicationInfoResource had a nested class ApplicationInfo.

It seems the Spring Boot Dev Tools was using a different class loader.

The exception I was getting

2017-05-01 17:47:39.588 WARN 1516 --- [nio-8080-exec-9] .m.m.a.ExceptionHandlerExceptionResolver : Resolved exception caused by Handler execution: org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.IllegalAccessError: tried to access class com.gt.web.rest.ApplicationInfo from class com.gt.web.rest.ApplicationInfoResource$$EnhancerBySpringCGLIB$$59ce500c

Solution

I moved the nested class ApplicationInfo to a separate .java file and got rid of the problem.

You should use TEXT (storing unlimited number of characters) for the sake of forward compatibility. Hashing algorithms (need to) become stronger over time and thus this database field will need to support more characters over time. Additionally depending on your migration strategy you may need to store new and old hashes in the same field, so fixing the length to one type of hash is not recommended.

Within Spring Boot 2.4 it is

sec:authorize="hasAnyRole('ROLE_ADMIN')

Ensure that you have

thymeleaf-extras-springsecurity5

in your dependencies. Also make sure that you include the namespace

xmlns:sec="http://www.thymeleaf.org/extras/spring-security"

in your html...

I use this - it never fails:

startingpoint = 'blah'
if sys.argv[1:]:
   startingpoint = sys.argv[1]

delete will delete the object property, but will not reindex the array or update its length. This makes it appears as if it is undefined:

> myArray = ['a', 'b', 'c', 'd']
  ["a", "b", "c", "d"]
> delete myArray[0]
  true
> myArray[0]
  undefined

Note that it is not in fact set to the value undefined, rather the property is removed from the array, making it appear undefined. The Chrome dev tools make this distinction clear by printing empty when logging the array.

> myArray[0]
  undefined
> myArray
  [empty, "b", "c", "d"]

myArray.splice(start, deleteCount) actually removes the element, reindexes the array, and changes its length.

> myArray = ['a', 'b', 'c', 'd']
  ["a", "b", "c", "d"]
> myArray.splice(0, 2)
  ["a", "b"]
> myArray
  ["c", "d"]

You can't guarantee that you're always going to get String objects back, or that the object you're working with in the List implements a way to ignore case.

If you do want to compare Strings in a collection to something independent of case, you'd want to iterate over the collection and compare them without case.

String word = "Some word";
List<String> aList = new ArrayList<>(); // presume that the list is populated

for(String item : aList) {
    if(word.equalsIgnoreCase(item)) {
        // operation upon successful match
    }
}

I cloned the repository with HTTPS URL instead of SSH URL hence even after adding the SSH Key it was asking me for password on Bash Shell.

I just edited the ./.git/config file and changed the value of url variable by simply replacing the https:// to ssh://

E.g.

[core]
        ...
        ...
        ...
[remote "origin"]
        url = https://<username>@bitbucket.org/<username>/<repository_name>.git
        fetch = +refs/heads/*:refs/remotes/origin/*
        ...
        ...
        ...

Changed to:

[core]
        ...
        ...
        ...
[remote "origin"]
        url = ssh://<username>@bitbucket.org/<username>/<repository_name>.git
        fetch = +refs/heads/*:refs/remotes/origin/*
        ...
        ...
        ...

In .NET Core I changed the onDelete option to ReferencialAction.NoAction

         constraints: table =>
            {
                table.PrimaryKey("PK_Schedule", x => x.Id);
                table.ForeignKey(
                    name: "FK_Schedule_Teams_HomeId",
                    column: x => x.HomeId,
                    principalTable: "Teams",
                    principalColumn: "Id",
                    onDelete: ReferentialAction.NoAction);
                table.ForeignKey(
                    name: "FK_Schedule_Teams_VisitorId",
                    column: x => x.VisitorId,
                    principalTable: "Teams",
                    principalColumn: "Id",
                    onDelete: ReferentialAction.NoAction);
            });

You can use undocumented method android.app.ActivityThread.currentPackageName() :

Class<?> clazz = Class.forName("android.app.ActivityThread");
Method method  = clazz.getDeclaredMethod("currentPackageName", null);
String appPackageName = (String) method.invoke(clazz, null);

Caveat: This must be done on the main thread of the application.

The difference between from datetime import datetime and normal import datetime is that , you are dealing with a module at one time and a class at other.

The strptime function only exists in the datetime class so you have to import the class with the module otherwise you have to specify datetime twice when calling this function.

The thing here is that , the class name and the module name has been given the same name so it creates a bit of confusuion.

Use this.

java.util.Date date = new Date("Sat Dec 01 00:00:00 GMT 2012");
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
String format = formatter.format(date);
System.out.println(format);

you will get the output as

2012-12-01

What you can do is to hide the ReCaptcha Control behind a div. Then make your styling on this div. And set the css "pointer-events: none" on it, so you can click through the div (Click through a DIV to underlying elements).

The checkbox should be in a place where the user is clicking.

Or if You are little less on the evangelist's side You can do a little ugly way I'm using. In deploy_template there are commits I want to copy on my master as branch deploy

git branch deploy deploy_template
git checkout deploy
git rebase master

This will create new branch deploy (I use -f to overwrite existing deploy branch) on deploy_template, then rebase this new branch onto master, leaving deploy_template untouched.

You can use FFserver to stream a video using RTSP.

Just change console syntax to something like this:

ffmpeg -i space.mp4 -vcodec libx264 -tune zerolatency -crf 18 http://localhost:1234/feed1.ffm

Create a ffserver.config file (sample) where you declare HTTPPort, RTSPPort and SDP stream. Your config file could look like this (some important stuff might be missing):

HTTPPort 1234
RTSPPort 1235

<Feed feed1.ffm>
        File /tmp/feed1.ffm
        FileMaxSize 2M
        ACL allow 127.0.0.1
</Feed>

<Stream test1.sdp>
    Feed feed1.ffm
    Format rtp
    Noaudio
    VideoCodec libx264
    AVOptionVideo flags +global_header
    AVOptionVideo me_range 16
    AVOptionVideo qdiff 4
    AVOptionVideo qmin 10
    AVOptionVideo qmax 51
    ACL allow 192.168.0.0 192.168.255.255
</Stream>

With such setup you can watch the stream with i.e. VLC by typing:

rtsp://192.168.0.xxx:1235/test1.sdp

Here is the FFserver documentation.

First use

git pull https://github.com/username/repository master

and then try

git push -u origin master

Here is a way to center content both vertically and horizontally in any situation, which is useful when you do not know the width or height or both:

CSS

#container {
    display: table;
    width: 300px; /* not required, just for example */
    height: 400px; /* not required, just for example */
}

#update {
    display: table-cell;
    vertical-align: middle;
    text-align: center;
}

HTML

<div id="container">
    <a id="update" href="#">
        <i class="icon-refresh"></i>
    </a>
</div>

JSFiddle

Note that the width and height values are just for demonstration here, you can change them to anything you want (or remove them entirely) and it will still work because the vertical centering here is a product of the way the table-cell display property works.

Just want to add this for the future programmer.

This code limits the date min and max. The year is fully controlled by getting the current year as max year.

Hope this could help to anyone.

Here's the code.

var dateToday = new Date();
var yrRange = '2014' + ":" + (dateToday.getFullYear());

$(function () {
    $("[id$=txtDate]").datepicker({
        showOn: 'button',
        changeMonth: true,
        changeYear: true,
        showButtonPanel: true,
        buttonImageOnly: true,
        yearRange: yrRange,
        buttonImage: 'calendar3.png',
        buttonImageOnly: true,
        minDate: new Date(2014,1-1,1),
        maxDate: '+50Y',
        inline:true
    });
});

Try

python --version 

or

python -V

This will return a current python version in terminal.

In Ubuntu 10.04 (Lucid), I could successfully pip install scipy (within a virtualenv) after installing some of its dependencies, in particular:

$ sudo apt-get install libamd2.2.0 libblas3gf libc6 libgcc1 libgfortran3 liblapack3gf libumfpack5.4.0 libstdc++6 build-essential gfortran libatlas-sse2-dev python-all-dev

1 You can use string.Replace method

var sample = "testtesttesttest#replace#testtesttest";
var result = sample.Replace("#replace#", yourValue);

2 You can also use string.Format

var result = string.Format("your right part {0} Your left Part", yourValue);

3 You can use Regex class

For setting Marquee programatically

TextView textView = (TextView) this.findViewById(R.id.textview_marquee);  
textView.setEllipsize(TruncateAt.MARQUEE);
textView.setMarqueeRepeatLimit(-1);
textView.setText("General Information... general information... General Information");
textView.setSelected(true);
textView.setSingleLine(true);

I had a PFX file and needed to create KEY file for NGINX, so I did this:

openssl pkcs12 -in file.pfx -out file.key -nocerts -nodes

Then I had to edit the KEY file and remove all content up to -----BEGIN PRIVATE KEY-----. After that NGINX accepted the KEY file.

https://docs.python.org/3/library/pickle.html

The pickle protocol formats:

Protocol version 0 is the original “human-readable” protocol and is backwards compatible with earlier versions of Python.

Protocol version 1 is an old binary format which is also compatible with earlier versions of Python.

Protocol version 2 was introduced in Python 2.3. It provides much more efficient pickling of new-style classes. Refer to PEP 307 for information about improvements brought by protocol 2.

Protocol version 3 was added in Python 3.0. It has explicit support for bytes objects and cannot be unpickled by Python 2.x. This is the default protocol, and the recommended protocol when compatibility with other Python 3 versions is required.

Protocol version 4 was added in Python 3.4. It adds support for very large objects, pickling more kinds of objects, and some data format optimizations. Refer to PEP 3154 for information about improvements brought by protocol 4.

From the document

npm-start :

This runs an arbitrary command specified in the package's "start" property of its "scripts" object. If no "start" property is specified on the "scripts" object, it will run node server.js.

which means it will call the start scripts inside the package.json

"scripts": {
"start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite --baseDir ./app --port 8001\" ",
"lite": "lite-server",
 ...
}

ng serve:

Provided by angular/angular-cli to start angular2 apps which created by angular-cli. when you install angular-cli, it will create ng.cmd under C:\Users\name\AppData\Roaming\npm (for windows) and execute "%~dp0\node.exe" "%~dp0\node_modules\angular-cli\bin\ng" %*

So using npm start you can make your own execution where is ng serve is only for angular-cli

See Also : What happens when you run ng serve?

It took me a while to figure out this because the normal "make install" has been removed and I don't use cmake. Here is my experience to share. At work, I don't have root access on Linux, so I installed the Google test framework under my home directory: ~/usr/gtest/.

To install the package in ~/usr/gtest/ as shared libraries, together with sample build as well:

$ mkdir ~/temp
$ cd ~/temp
$ unzip gtest-1.7.0.zip 
$ cd gtest-1.7.0
$ mkdir mybuild
$ cd mybuild
$ cmake -DBUILD_SHARED_LIBS=ON -Dgtest_build_samples=ON -G"Unix Makefiles" ..
$ make
$ cp -r ../include/gtest ~/usr/gtest/include/
$ cp lib*.so ~/usr/gtest/lib

To validate the installation, use the following test.c as a simple test example:

    #include <gtest/gtest.h>
    TEST(MathTest, TwoPlusTwoEqualsFour) {
        EXPECT_EQ(2 + 2, 4);
    }

    int main(int argc, char **argv) {
        ::testing::InitGoogleTest( &argc, argv );
        return RUN_ALL_TESTS();
    }

To compile:

    $ export GTEST_HOME=~/usr/gtest
    $ export LD_LIBRARY_PATH=$GTEST_HOME/lib:$LD_LIBRARY_PATH
    $ g++ -I $GTEST_HOME/include -L $GTEST_HOME/lib -lgtest -lgtest_main -lpthread test.cpp 

I manage to solve this in excel 97-2003, in a file with .xls extension this way: I went to the page where I had the linked data, with the cursor over the imported data table, go to tab Design --> External Data Table --> Unlink Unlink all tables (conections), delete all conections in Data --> Conections --> Conections save your work and done! regards, Dan

The CSS class that can be changed to add a image to the JQuery slider handle is called ".ui-slider-horizontal .ui-slider-handle".

The following code shows a demo:

<!DOCTYPE html>
<html>
<head>
  <link type="text/css" href="http://jqueryui.com/latest/themes/base/ui.all.css" rel="stylesheet" />
  <script type="text/javascript" src="http://jqueryui.com/latest/jquery-1.3.2.js"></script>
  <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.core.js"></script>
  <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.slider.js"></script>
  <style type="text/css">
  .ui-slider-horizontal .ui-state-default {background: white url(http://stackoverflow.com/content/img/so/vote-arrow-down.png) no-repeat scroll 50% 50%;}
  </style>
  <script type="text/javascript">
  $(document).ready(function(){
    $("#slider").slider();
  });
  </script>
</head>
<body>
<div id="slider"></div>
</body>
</html>

I think registering a handle option was the old way of doing it and no longer supported in JQuery-ui 1.7.2?

In my case the form (which I cannot modify) was always sending POST.
While in my Web Service I tried to implement GET method (due to lack of documentation I expected that both are allowed).

Thus, it was failing as "Not allowed", since there was no method with POST type on my end.

Changing @GET to @POST above my WS method fixed the issue.

There is no python3.exe file, that is why it fails.

Try:

py

instead.

py is just a launcher for python.exe. If you have more than one python versions installed on your machine (2.x, 3.x) you can specify what version of python to launch by

py -2 or py -3

Could do it with :contains() selector as well:

$('#toptitle:contains("Profil")').text("New word");

example: http://jsfiddle.net/niklasvh/xPRzr/

From IE7 onwards you can simply use

#footer {
    position:fixed;
    bottom:0;
}

See caniuse for support.

A workaround is to transpose the DataFrame and iterate over the rows.

for column_name, column in df.transpose().iterrows():
    print column_name

we are using below configuration to do something similar

    var gulp = require('gulp'),
    async = require("async"),
    less = require('gulp-less'),
    minifyCSS = require('gulp-minify-css'),
    uglify = require('gulp-uglify'),
    concat = require('gulp-concat'),
    gulpDS = require("./gulpDS"),
    del = require('del');

// CSS & Less
var jsarr = [gulpDS.jsbundle.mobile, gulpDS.jsbundle.desktop, gulpDS.jsbundle.common];
var cssarr = [gulpDS.cssbundle];

var generateJS = function() {

    jsarr.forEach(function(gulpDSObject) {
        async.map(Object.keys(gulpDSObject), function(key) {
            var val = gulpDSObject[key]
            execGulp(val, key);
        });

    })
}

var generateCSS = function() {
    cssarr.forEach(function(gulpDSObject) {
        async.map(Object.keys(gulpDSObject), function(key) {
            var val = gulpDSObject[key];
            execCSSGulp(val, key);
        })
    })

Don't use read without arguments. It's very slow. Better read it to buffer and move it to file quickly.

Use bufferedInputStream because it supports binary reading.

And it's all.

You can see the resolutions for those categories in the Table 2, in this section: http://developer.android.com/guide/practices/screens_support.html#testing

You mention the most commonly implemented, which is Adjacency List: https://blogs.msdn.microsoft.com/mvpawardprogram/2012/06/25/hierarchies-convert-adjacency-list-to-nested-sets

There are other models as well, including materialized path and nested sets: http://communities.bmc.com/communities/docs/DOC-9902

Joe Celko has written a book on this subject, which is a good reference from a general SQL perspective (it is mentioned in the nested set article link above).

Also, Itzik Ben-Gann has a good overview of the most common options in his book "Inside Microsoft SQL Server 2005: T-SQL Querying".

The main things to consider when choosing a model are:

1) Frequency of structure change - how frequently does the actual structure of the tree change. Some models provide better structure update characteristics. It is important to separate structure changes from other data changes however. For example, you may want to model a company's organizational chart. Some people will model this as an adjacency list, using the employee ID to link an employee to their supervisor. This is usually a sub-optimal approach. An approach that often works better is to model the org structure separate from employees themselves, and maintain the employee as an attribute of the structure. This way, when an employee leaves the company, the organizational structure itself does not need to be changes, just the association with the employee that left.

2) Is the tree write-heavy or read-heavy - some structures work very well when reading the structure, but incur additional overhead when writing to the structure.

3) What types of information do you need to obtain from the structure - some structures excel at providing certain kinds of information about the structure. Examples include finding a node and all its children, finding a node and all its parents, finding the count of child nodes meeting certain conditions, etc. You need to know what information will be needed from the structure to determine the structure that will best fit your needs.

If you know what class the field is on you can access it using reflection. This example (it's in Groovy but the method calls are identical) gets a Field object for the class Foo and gets its value for the object b. It shows that you don't have to care about the exact concrete class of the object, what matters is that you know the class the field is on and that that class is either the concrete class or a superclass of the object.

groovy:000> class Foo { def stuff = "asdf"}
===> true
groovy:000> class Bar extends Foo {}
===> true
groovy:000> b = new Bar()
===> Bar@1f2be27
groovy:000> f = Foo.class.getDeclaredField('stuff')
===> private java.lang.Object Foo.stuff
groovy:000> f.getClass()
===> class java.lang.reflect.Field
groovy:000> f.setAccessible(true)
===> null
groovy:000> f.get(b)
===> asdf

I ran into the same problem. I wanted tabs to work like buffers and I never quite manage to get them to. The solution that I finally settled on was to make buffers behave like tabs!

Check out the plugin called Mini Buffer Explorer, once installed and configured, you'll be able to work with buffers virtaully the same way as tabs without losing any functionality.

This might be overkill - but be careful doing anything which relies on the extension of PHP files being .php - what if someone comes along later and adds handlers for .php4 or even .html so they're handled by PHP. You might be better off serving files out of those directories from a different instance of Apache or something, which only serves static content.

You're asking the wrong question. The codebehind (controller) has nothing to do with what the frontend does. In fact, that's the strength of MVC -- you separate the code/concept from the view.

If you want an action to open in a new window, then links to that action need to tell the browser to open a new window when clicked.

A pseudo example: <a href="NewWindow" target="_new">Click Me</a>

And that's all there is to it. Set the target of links to that action.

$("#closeLink").click(closeIt);

Let's say you want to call your function passing some args to it i.e., closeIt(1, false). Then, you should build an anonymous function and call closeIt from it.

$("#closeLink").click(function() {
    closeIt(1, false);
});

According to the String Literals / Metacharacters documentation page, they are:

<([{\^-=$!|]})?*+.>

Also it would be cool to have that list refereed somewhere in code, but I don't know where that could be...

it depends what sort of t-test you want to do (one sided or two sided dependent or independent) but it should be as simple as:

from scipy.stats import ttest_ind

cat1 = my_data[my_data['Category']=='cat1']
cat2 = my_data[my_data['Category']=='cat2']

ttest_ind(cat1['values'], cat2['values'])
>>> (1.4927289925706944, 0.16970867501294376)

it returns a tuple with the t-statistic & the p-value

see here for other t-tests http://docs.scipy.org/doc/scipy/reference/stats.html

Make sure you really need to invert the matrix. This is often unnecessary and can be numerically unstable. When most people ask how to invert a matrix, they really want to know how to solve Ax = b where A is a matrix and x and b are vectors. It's more efficient and more accurate to use code that solves the equation Ax = b for x directly than to calculate A inverse then multiply the inverse by B. Even if you need to solve Ax = b for many b values, it's not a good idea to invert A. If you have to solve the system for multiple b values, save the Cholesky factorization of A, but don't invert it.

See Don't invert that matrix.

No magic involved, just subtract from the offset top of the element

$('html, body').animate({scrollTop: $('#contact').offset().top -100 }, 'slow');

Found a really helpful link for that. Using SQLCMD for this is really easier than solving this with a stored procedure

Running command node -v will be able to confirm if it is installed, however it will not be able to confirm if it is NOT installed. (Executable may not be on your PATH)

Two ways you can check if it is actually installed:

1. Check default install location C:\Program Files\nodejs\

or

2. Go to System Settings -> Add or Remove Programs and filter by node, it should show you if you have it installed. For me, it shows as title:"Node.js" and description "Node.js Foundation", with no version specified. Install size is 52.6MB

If you don't have it installed, get it from here https://nodejs.org/en/download/

The manual for json_encode specifies this:

All string data must be UTF-8 encoded.

Thus, try array_mapping utf8_encode() to your array before you encode it:

$arr = array_map('utf8_encode', $arr);
$json = json_encode($arr);

// {"funds":"ComStage STOXX\u00c2\u00aeEurope 600 Techn NR ETF"}

For reference, take a look at the differences between the three examples on this fiddle. The first doesn't use character encoding, the second uses htmlentities and the third uses utf8_encode - they all return different results.

For consistency, you should use utf8_encode().

Docs

• json_encode()
• utf8_encode()
• array_map()

distcc can also be used to distribute compiles not only on the current machine, but also on other machines in a farm that have distcc installed.

YUI minifier

This is caused by editing file in windows and importing and executing in unix.

dos2unix -k -o filename should do the trick.

Maybe I don't completely understand the accepted answer so it didn't work for me.

What i did was simply to check if the variable is null, assign it to a known value from my database. Which seems to be similar to the accepted answer whereby you first declare an known value and set it to selected

<select name="department">
    <c:forEach var="item" items="${dept}">
        <option value="${item.key}">${item.value}</option>
    </c:forEach>
</select>

because none of the options are selected, thus item = null

<%
    if(item == null){
        item = "selectedDept"; //known value from your database
    }
%>

This way if the user then selects another option, my IF clause will not catch it and assign to the fixed value that was declared at the start. My concept could be wrong here but it works for me

In Typescript 2 you can use Undefined type to check for undefined values. So if you declare a variable as:

let uemail : string | undefined;

Then you can check if the variable z is undefined as:

if(uemail === undefined)
{

}

If you just want to open the Google Chrome from terminal instantly for once then open -a "Google Chrome" works fine from Mac Terminal.

If you want to use an alias to call Chrome from terminal then you need to edit the bash profile and add an alias on ~/.bash_profile or ~/.zshrc file.The steps are below :

• Edit ~/.bash_profile or ~/.zshrc file and add the following line alias chrome="open -a 'Google Chrome'"
• Save and close the file.
• Logout and relaunch Terminal
• Type chrome filename for opening a local file.
• Type chrome url for opening url.

Here is what I use.

Write-Host -NoNewLine 'Press any key to continue...';
$null = $Host.UI.RawUI.ReadKey('NoEcho,IncludeKeyDown');

I found an workaround on the web. I added to /etc/nginx/conf.d/default.conf the following:

location ~ \.css {
    add_header  Content-Type    text/css;
}
location ~ \.js {
    add_header  Content-Type    application/x-javascript;
}

The problem now is that a request to my css file isn't redirected well, as if root is not correctly set. In error.log I see

2012/04/11 14:01:23 [error] 7260#0: *2 open() "/etc/nginx//html/style.css"

So as a second workaround I added the root to each defined location. Now it works, but seems a little redundant. Isn't root inherited from / location ?

I solved it upgrading the lxml version with:

pip install --upgrade lxml

DLL Export Viewer by NirSoft can be used to display exported functions in a DLL.

This utility displays the list of all exported functions and their virtual memory addresses for the specified DLL files. You can easily copy the memory address of the desired function, paste it into your debugger, and set a breakpoint for this memory address. When this function is called, the debugger will stop in the beginning of this function.

Yes, if you're having problems with StaleElementReferenceExceptions it's because there is a race condition. Consider the following scenario:

WebElement element = driver.findElement(By.id("foo"));
// DOM changes - page is refreshed, or element is removed and re-added
element.click();

Now at the point where you're clicking the element, the element reference is no longer valid. It's close to impossible for WebDriver to make a good guess about all the cases where this might happen - so it throws up its hands and gives control to you, who as the test/app author should know exactly what may or may not happen. What you want to do is explicitly wait until the DOM is in a state where you know things won't change. For example, using a WebDriverWait to wait for a specific element to exist:

// times out after 5 seconds
WebDriverWait wait = new WebDriverWait(driver, 5);
    
// while the following loop runs, the DOM changes - 
// page is refreshed, or element is removed and re-added
wait.until(presenceOfElementLocated(By.id("container-element")));        

// now we're good - let's click the element
driver.findElement(By.id("foo")).click();

The presenceOfElementLocated() method would look something like this:

private static Function<WebDriver,WebElement> presenceOfElementLocated(final By locator) {
    return new Function<WebDriver, WebElement>() {
        @Override
        public WebElement apply(WebDriver driver) {
            return driver.findElement(locator);
        }
    };
}

You're quite right about the current Chrome driver being quite unstable, and you'll be happy to hear that the Selenium trunk has a rewritten Chrome driver, where most of the implementation was done by the Chromium developers as part of their tree.

PS. Alternatively, instead of waiting explicitly like in the example above, you can enable implicit waits - this way WebDriver will always loop up until the specified timeout waiting for the element to become present:

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS)

In my experience though, explicitly waiting is always more reliable.

    String.prototype.endsWith = function(substring, position) {
        substring = String(substring);

        var subLen = substring.length | 0;

        if( !subLen )return true;//Empty string

        var strLen = this.length;

        if( position === void 0 )position = strLen;
        else position = position | 0;

        if( position < 1 )return false;

        var fromIndex = (strLen < position ? strLen : position) - subLen;

        return (fromIndex >= 0 || subLen === -fromIndex)
            && (
                position === 0
                // if position not at the and of the string, we can optimise search substring
                //  by checking first symbol of substring exists in search position in current string
                || this.charCodeAt(fromIndex) === substring.charCodeAt(0)//fast false
            )
            && this.indexOf(substring, fromIndex) === fromIndex
        ;
    };
}

Benefits:

• This version is not just re-using indexOf.
• Greatest performance on long strings. Here is a speed test http://jsperf.com/starts-ends-with/4
• Fully compatible with ecmascript specification. It passes the tests

After many fruitful hours of exploring OCR libraries, bounding boxes and clustering algorithms - I found a solution so simple it makes you want to cry!

I hope you are using Linux;

pdftotext -layout NAME_OF_PDF.pdf

AMAZING!!

Now you have a nice text file with all the information lined up in nice columns, now it is trivial to format into a csv etc..

It is for times like this that I love Linux, these guys came up with AMAZING solutions to everything, and put it there for FREE!

I found this solution in this article

.parent-element {
  -webkit-transform-style: preserve-3d;
  -moz-transform-style: preserve-3d;
  transform-style: preserve-3d;
}

.element {
  position: relative;
  top: 50%;
  transform: translateY(-50%);
}

It work like a charm if the height of element is not fixed.

Here's some easy way to get slice of the map-keys.

// Return keys of the given map
func Keys(m map[string]interface{}) (keys []string) {
    for k := range m {
        keys = append(keys, k)
    }
    return keys
}

// use `Keys` func
func main() {
    m := map[string]interface{}{
        "foo": 1,
        "bar": true,
        "baz": "baz",
    }
    fmt.Println(Keys(m)) // [foo bar baz]
}

I find myself forgetting how to do this every time as well so I just wrap the two one-liners that I need in a little class:

public class Utility
{
    /// <summary>
    /// Takes the full name of a resource and loads it in to a stream.
    /// </summary>
    /// <param name="resourceName">Assuming an embedded resource is a file
    /// called info.png and is located in a folder called Resources, it
    /// will be compiled in to the assembly with this fully qualified
    /// name: Full.Assembly.Name.Resources.info.png. That is the string
    /// that you should pass to this method.</param>
    /// <returns></returns>
    public static Stream GetEmbeddedResourceStream(string resourceName)
    {
        return Assembly.GetExecutingAssembly().GetManifestResourceStream(resourceName);
    }

    /// <summary>
    /// Get the list of all emdedded resources in the assembly.
    /// </summary>
    /// <returns>An array of fully qualified resource names</returns>
    public static string[] GetEmbeddedResourceNames()
    {
        return Assembly.GetExecutingAssembly().GetManifestResourceNames();
    }
}

Last 5 rows retrieve in mysql

mycollection.find_one_and_update({"_id": mongo_id}, 
                                 {"$set": {"newfield": "abc"}})

should work splendidly for you. If there is no document of id mongo_id, it will fail, unless you also use upsert=True. This returns the old document by default. To get the new one, pass return_document=ReturnDocument.AFTER. All parameters are described in the API.

The method was introduced for MongoDB 3.0. It was extended for 3.2, 3.4, and 3.6.

$this refers to the current class object, self refers to the current class (Not object). The class is the blueprint of the object. So you define a class, but you construct objects.

So in other words, use self for static and this for none-static members or methods.

also in child/parent scenario self / parent is mostly used to identified child and parent class members and methods.

For Query parameters like domain.com/test?format=json&type=mini format, then you can easily receive it via - req.query.

app.get('/test', function(req, res){
  var format = req.query.format,
      type = req.query.type;
});

I think the problem was the two single quotes missing.

This is the sql I run to the MSSMS:

WHERE checktime >= '2019-01-24 15:01:36.000' AND checktime <= '2019-01-25 16:01:36.000'

As you can see there are two single quotes, so your codes must be:

string sqlFormattedDate = "'" + myDateTime.Date.ToString("yyyy-MM-dd") + " " + myDateTime.TimeOfDay.ToString("HH:mm:ss") + "'";

Use single quotes for every string in MSSQL or even in MySQL. I hope this helps.

This is my version of a drop shadow. I was going for a hazy shadow all around the shape and used this answer by Joakim Lundborg as my starting point.

With perl and Linux::Distribution, the cleanest solution for an old problem :

#!/bin/sh

perl -e '
    use Linux::Distribution qw(distribution_name distribution_version);

    my $linux = Linux::Distribution->new;
    if(my $distro = $linux->distribution_name()) {
          my $version = $linux->distribution_version();
          print "you are running $distro";
          print " version $version" if $version;
          print "\n";
    } else {
          print "distribution unknown\n";
    }

Composite primary keys are what you want where you want to create a many to many relationship with a fact table. For example, you might have a holiday rental package that includes a number of properties in it. On the other hand, the property could also be available as a part of a number of rental packages, either on its own or with other properties. In this scenario, you establish the relationship between the property and the rental package with a property/package fact table. The association between a property and a package will be unique, you will only ever join using property_id with the property table and/or package_id with the package table. Each relationship is unique and an auto_increment key is redundant as it won't feature in any other table. Hence defining the composite key is the answer.

You can iterate through the <li>s in the <ul> and stop when you find the right one.

function getIndex(li) {
    var lis = li.parentNode.getElementsByTagName('li');
    for (var i = 0, len = lis.length; i < len; i++) {
        if (li === lis[i]) {
            return i;
        }
    }

}

I come across this problem when I tried to convert to Australian date format in excel. I split the cell with delimiter and used the following code from split cells then altered the issue areas.

=date(dd,mm,yy)

I am also getting the same error and the solution is first to check if the Git is installed or not in the system and if not please install it.

After installation, open Git Bash or Git Shell from Windows and go to your project (same way you go in command prompt using "cd path"). Git Shell is installed by default with Github windows installation.

Then run the same bower install command. It will work as expected.

The below screenshot shows the command using Git Shell

Just only copy and paste this code it will get your page content.

<?php
                $pageid = get_the_id();
                $content_post = get_post($pageid);
                $content = $content_post->post_content;
                $content = apply_filters('the_content', $content);
                $content = str_replace(']]>', ']]&gt;', $content);
                echo $content;
                ?>

You have already have container-selinux installed for version 3.7 check if the following docker-ce version works for you , it did for me.

sudo yum -y install docker-ce-cli.x86_64 1:19.03.5-3.el7

There are probably embedded tabs (CHAR(9)) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:

DECLARE @var NVARCHAR(255), @i INT;

SET @i = 1;

SELECT @var = AccountType FROM dbo.Account
  WHERE AccountNumber = 200
  AND AccountType LIKE '%Daily%';

CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));

WHILE @i <= LEN(@var)
BEGIN
  INSERT #x 
    SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));

  SET @i = @i + 1;
END

SELECT i,c,a FROM #x ORDER BY i;

You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.

if you want to select column with specific name then just do

A=mtcars[,which(conames(mtcars)==cols[1])]
#and then
colnames(mtcars)[A]=cols[1]

you can run it in loop as well reverse way to add dynamic name eg if A is data frame and xyz is column to be named as x then I do like this

A$tmp=xyz
colnames(A)[colnames(A)=="tmp"]=x

again this can also be added in loop

I had the same error here but with glassfish server. Maybe it can help. I needed to configure the glassfish-web.xml file with the content inside the <resources> from glassfish-resources.xml. As I got another error I could find this annotation in the server log:

Caused by: java.lang.RuntimeException: Error in parsing WEB-INF/glassfish-web.xml for archive [file:/C:/Users/Win/Documents/NetBeansProjects/svad/build/web/]: The xml element should be [glassfish-web-app] rather than [resources]

All I did then was to change the <resources> tag and apply <glassfish-web-app> in the glassfish-web.xml file.

Send as many inserts across the wire at one time as possible. The actual insert speed should be the same, but you will see performance gains from the reduction of network overhead.

I had the exact same error (on windows 7) and the cause was different. I solved it in a different way so I thought I'd add the cause and solution here for others.

Even though the error seemed to point to heroku really the error was saying "Heroku can't get to the git repository". I swore I had the same keys on all the servers because I created it and uploaded it to one after the other at the same time.

After spending almost a day on this I realized that because git was only showing me the fingerprint and not the actual key. I couldn't verify that it's key matched the one on my HD or heroku. I looked in the known hosts file and guess what... it shows the keys for each server and I was able to clearly see that the git and heroku public keys did not match.

1) I deleted all the files in my key folder, the key from github using their website, and the key from heroku using git bash and the command heroku keys:clear

2) Followed github's instructions here to generate a new key pair and upload the public key to git

3) using git bash- heroku keys:add to upload the same key to heroku.

Now git push heroku master works.

what a nightmare, hope this helped somebody.

Here's one way:

import os
import shutil

def copy_over(path, from_name, to_name):
  for path, dirname, fnames in os.walk(path):
    for fname in fnames:
      if fname == from_name:
        shutil.copy(os.path.join(path, from_name), os.path.join(path, to_name))


copy_over('.', 'index.tpl', 'index.html')

You don't need a derived table at all for this.

Just put the INTO after the first SELECT

SELECT top(100)* 
INTO tmpFerdeen
FROM Customers
UNION All
SELECT top(100)* 
FROM CustomerEurope
UNION All
SELECT top(100)* 
FROM CustomerAsia
UNION All
SELECT top(100)* 
FROM CustomerAmericas

Two ways to achieve it.

1) Need to start the dialer via code, without user interaction.

You need Action_Dial,

use below code it will open Dialer with number specified

Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:0123456789"));
startActivity(intent); 

The 'tel:' prefix is required, otherwhise the following exception will be thrown: java.lang.IllegalStateException: Could not execute method of the activity.

Action_Dial doesn't require any permission.

If you want to initiate the call directly without user's interaction , You can use action Intent.ACTION_CALL. In this case, you must add the following permission in your AndroidManifest.xml:

<uses-permission android:name="android.permission.CALL_PHONE" />

2) Need user to click on Phone_Number string and start the call.

android:autoLink="phone" 

You need to use TextView with below property.

android:autoLink="phone" android:linksClickable="true" a textView property

You don't need to use intent or to get permission via this way.

Update Model from Database doesn't works for me.

I had to remove the conflicted entity, then execute Update Model from Database, lastly rebuild the solution. After that, everything works fine.
