Programs & Examples On #Cue

Note: The following applies to Windows PowerShell.
See the next section for the cross-platform PowerShell Core (v6+) edition.

• On PSv5.1 or higher, where > and >> are effectively aliases of Out-File, you can set the default encoding for > / >> / Out-File via the $PSDefaultParameterValues preference variable:

  • $PSDefaultParameterValues['Out-File:Encoding'] = 'utf8'

• On PSv5.0 or below, you cannot change the encoding for > / >>, but, on PSv3 or higher, the above technique does work for explicit calls to Out-File.
  (The $PSDefaultParameterValues preference variable was introduced in PSv3.0).

• On PSv3.0 or higher, if you want to set the default encoding for all cmdlets that support
  an -Encoding parameter (which in PSv5.1+ includes > and >>), use:

  • $PSDefaultParameterValues['*:Encoding'] = 'utf8'

If you place this command in your $PROFILE, cmdlets such as Out-File and Set-Content will use UTF-8 encoding by default, but note that this makes it a session-global setting that will affect all commands / scripts that do not explicitly specify an encoding via their -Encoding parameter.

Similarly, be sure to include such commands in your scripts or modules that you want to behave the same way, so that they indeed behave the same even when run by another user or a different machine; however, to avoid a session-global change, use the following form to create a local copy of $PSDefaultParameterValues:

• $PSDefaultParameterValues = @{ '*:Encoding' = 'utf8' }

Caveat: PowerShell, as of v5.1, invariably creates UTF-8 files _with a (pseudo) BOM_, which is customary only in the Windows world - Unix-based utilities do not recognize this BOM (see bottom); see this post for workarounds that create BOM-less UTF-8 files.

For a summary of the wildly inconsistent default character encoding behavior across many of the Windows PowerShell standard cmdlets, see the bottom section.

The automatic $OutputEncoding variable is unrelated, and only applies to how PowerShell communicates with external programs (what encoding PowerShell uses when sending strings to them) - it has nothing to do with the encoding that the output redirection operators and PowerShell cmdlets use to save to files.

Optional reading: The cross-platform perspective: PowerShell Core:

PowerShell is now cross-platform, via its PowerShell Core edition, whose encoding - sensibly - defaults to BOM-less UTF-8, in line with Unix-like platforms.

• This means that source-code files without a BOM are assumed to be UTF-8, and using > / Out-File / Set-Content defaults to BOM-less UTF-8; explicit use of the utf8 -Encoding argument too creates BOM-less UTF-8, but you can opt to create files with the pseudo-BOM with the utf8bom value.

• If you create PowerShell scripts with an editor on a Unix-like platform and nowadays even on Windows with cross-platform editors such as Visual Studio Code and Sublime Text, the resulting *.ps1 file will typically not have a UTF-8 pseudo-BOM:

  • This works fine on PowerShell Core.
  • It may break on Windows PowerShell, if the file contains non-ASCII characters; if you do need to use non-ASCII characters in your scripts, save them as UTF-8 with BOM.
    Without the BOM, Windows PowerShell (mis)interprets your script as being encoded in the legacy "ANSI" codepage (determined by the system locale for pre-Unicode applications; e.g., Windows-1252 on US-English systems).

• Conversely, files that do have the UTF-8 pseudo-BOM can be problematic on Unix-like platforms, as they cause Unix utilities such as cat, sed, and awk - and even some editors such as gedit - to pass the pseudo-BOM through, i.e., to treat it as data.

  • This may not always be a problem, but definitely can be, such as when you try to read a file into a string in bash with, say, text=$(cat file) or text=$(<file) - the resulting variable will contain the pseudo-BOM as the first 3 bytes.

Inconsistent default encoding behavior in Windows PowerShell:

Regrettably, the default character encoding used in Windows PowerShell is wildly inconsistent; the cross-platform PowerShell Core edition, as discussed in the previous section, has commendably put and end to this.

Note:

• The following doesn't aspire to cover all standard cmdlets.

• Googling cmdlet names to find their help topics now shows you the PowerShell Core version of the topics by default; use the version drop-down list above the list of topics on the left to switch to a Windows PowerShell version.

• As of this writing, the documentation frequently incorrectly claims that ASCII is the default encoding in Windows PowerShell - see this GitHub docs issue.

Cmdlets that write:

Out-File and > / >> create "Unicode" - UTF-16LE - files by default - in which every ASCII-range character (too) is represented by 2 bytes - which notably differs from Set-Content / Add-Content (see next point); New-ModuleManifest and Export-CliXml also create UTF-16LE files.

Set-Content (and Add-Content if the file doesn't yet exist / is empty) uses ANSI encoding (the encoding specified by the active system locale's ANSI legacy code page, which PowerShell calls Default).

Export-Csv indeed creates ASCII files, as documented, but see the notes re -Append below.

Export-PSSession creates UTF-8 files with BOM by default.

New-Item -Type File -Value currently creates BOM-less(!) UTF-8.

The Send-MailMessage help topic also claims that ASCII encoding is the default - I have not personally verified that claim.

Start-Transcript invariably creates UTF-8 files with BOM, but see the notes re -Append below.

Re commands that append to an existing file:

>> / Out-File -Append make no attempt to match the encoding of a file's existing content. That is, they blindly apply their default encoding, unless instructed otherwise with -Encoding, which is not an option with >> (except indirectly in PSv5.1+, via $PSDefaultParameterValues, as shown above). In short: you must know the encoding of an existing file's content and append using that same encoding.

Add-Content is the laudable exception: in the absence of an explicit -Encoding argument, it detects the existing encoding and automatically applies it to the new content.^{Thanks, js2010}. Note that in Windows PowerShell this means that it is ANSI encoding that is applied if the existing content has no BOM, whereas it is UTF-8 in PowerShell Core.

This inconsistency between Out-File -Append / >> and Add-Content, which also affects PowerShell Core, is discussed in this GitHub issue.

Export-Csv -Append partially matches the existing encoding: it blindly appends UTF-8 if the existing file's encoding is any of ASCII/UTF-8/ANSI, but correctly matches UTF-16LE and UTF-16BE.
To put it differently: in the absence of a BOM, Export-Csv -Append assumes UTF-8 is, whereas Add-Content assumes ANSI.

Start-Transcript -Append partially matches the existing encoding: It correctly matches encodings with BOM, but defaults to potentially lossy ASCII encoding in the absence of one.

Cmdlets that read (that is, the encoding used in the absence of a BOM):

Get-Content and Import-PowerShellDataFile default to ANSI (Default), which is consistent with Set-Content.
ANSI is also what the PowerShell engine itself defaults to when it reads source code from files.

By contrast, Import-Csv, Import-CliXml and Select-String assume UTF-8 in the absence of a BOM.

If you want to keep the modal responsive use % of width instead of pixels. You can do it in-line (see below) or with CSS.

<div class="modal fade" id="phpModal" role="dialog">
            <div class="modal-dialog modal-lg" style="width:80%;">
                <div class="modal-content">
                    <div class="modal-header">
                        <button type="button" class="close" data-dismiss="modal">&times;</button>
                        <h4 class="modal-title">HERE YOU TITLE</h4>
                    </div>
                    <div class="modal-body helpModal phpModal">
                        HERE YOUR CONTENT
                    </div>
                </div>
            </div>
        </div>

If you use CSS, you can even do different % for modal-sm and modal-lg.

You can also modify your config/routes.rb file like:

 get 'ajax/:action', to: 'ajax#:action', :defaults => { :format => 'json' }

Which will default the format to json. It is working fine for me in Rails 4.

Or if you want to go even further and you are using namespaces, you can cut down the duplicates:

namespace :api, defaults: {format: 'json'} do
   #your controller routes here ...
end

with the above everything under /api will be formatted as json by default.

to center vertically and horizontally use this:

position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%,-50%);

I tried compile a java 8 project with JDK 12 and has the same issue. None of previous answer solved my problem.

I changed o Shortel Command Line to "JAR Manifest" and worked like a charm.

It seems that you have invalid JSON. In that case, that's totally dependent on the data the server sends you which you have not shown. I would suggest running the response through a JSON validator.

I was uninstalled compass 1.0.1 and install compass 0.12.7, this fix problem for me

$ sudo gem uninstall compass
$ sudo gem install compass -v 0.12.7

I have macOS Catalina (10.15.6) and PostgreSQL 12.

When I run brew services start postgresql, brew said it start PostgreSQL without problem, but it does not show when I get ps auxw | grep post.

To solve it, I install Postgres.app from this link, and install and press Init button.

It will find your databases and show it to you.

Resolved this issue by using http(s) when accessing the endpoint. The route I was accessing was not available over http. So I would say verify the protocols for which the route is available.

Because this captures all exceptions. It's unlikely that your program can recover from any of them.

You should handle only exceptions that you know how to recover from. If you don't anticipate a certain kind of exception, don't handle it, crash loudly (write details to the log), then diagnose logs and fix code.

Swallowing exceptions is bad, don't do this.

What do you get from running which port as your regular user account? Try it from a freshly opened terminal. Try again after renaming .bash_profile to .profile. Can you run port as a regular user, even with no arguments?

Not certain what the HTML looks like (that would help with answers). If it's

<div class="testimonials content">stuff</div>

then simply remove the space in your css. A la...

.testimonials.content { css here }

UPDATE:

Okay, after seeing HTML see if this works...

.testimonials .wrapper .content { css here }

or just

.testimonials .wrapper { css here }

or

.desc-container .wrapper { css here }

all 3 should work.

Browser scrollbars don't work at all on iPhone/iPad. At work we are using custom JavaScript scrollbars like jScrollPane to provide a consistent cross-browser UI: http://jscrollpane.kelvinluck.com/

It works very well for me - you can make some really beautiful custom scrollbars that fit the design of your site.

The m000493 method seems to perform some kind of XOR encryption. This means that the same method can be used for both encrypting and decrypting the text. All you have to do is reverse m0001cd:

string p0 = Encoding.UTF8.GetString(Convert.FromBase64String("OBFZDT..."));

string result = m000493(p0, "_p0lizei.");
//    result == "gaia^unplugged^Ta..."

with return m0001cd(builder3.ToString()); changed to return builder3.ToString();.

from otherfile import TheClass
theclass = TheClass()
# if you want to return the output of run
return theclass.run()  
# if you want to return run itself to be used later
return theclass.run

Change the end of comm system to:

if __name__ == '__main__':
    a_game = Comm_system()
    a_game.run()

It's those lines being always run that are causing it to be run when imported as well as when executed.

no you're just using it wrong. your is_number? has an argument. you called it without the argument

you should be doing is_number?(mystring)

you can force UTF8 with force_encoding(Encoding::UTF_8):

Example:

<%= yield.force_encoding(Encoding::UTF_8) %>

If you want to ensure a file is closed you should use the block form of File.open:

File.open("myFile.txt", "w") do |file|
  begin
    file << "#{content} \n"
  rescue
  #handle the error here
  end
end

Use the keyword next. If you do not want to continue to the next item, use break.

When next is used within a block, it causes the block to exit immediately, returning control to the iterator method, which may then begin a new iteration by invoking the block again:

f.each do |line|              # Iterate over the lines in file f
  next if line[0,1] == "#"    # If this line is a comment, go to the next
  puts eval(line)
end

When used in a block, break transfers control out of the block, out of the iterator that invoked the block, and to the first expression following the invocation of the iterator:

f.each do |line|             # Iterate over the lines in file f
  break if line == "quit\n"  # If this break statement is executed...
  puts eval(line)
end
puts "Good bye"              # ...then control is transferred here

And finally, the usage of return in a block:

return always causes the enclosing method to return, regardless of how deeply nested within blocks it is (except in the case of lambdas):

def find(array, target)
  array.each_with_index do |element,index|
    return index if (element == target)  # return from find
  end
  nil  # If we didn't find the element, return nil
end

Yes I think You can get it download and separately its Help files from: vbdecompiler.org Site. and there is a Video on YouTube which explains how to Use it to Get the Code from an exe file and Save it. I hope that I helped.

In theory, you can't deterministically find unused code. Theres a mathematical proof of this (well, this is a special case of a more general theorem). If you're curious, look up the Halting Problem.

This can manifest itself in Java code in many ways:

• Loading classes based on user input, config files, database entries, etc;
• Loading external code;
• Passing object trees to third party libraries;
• etc.

That being said, I use IDEA IntelliJ as my IDE of choice and it has extensive analysis tools for findign dependencies between modules, unused methods, unused members, unused classes, etc. Its quite intelligent too like a private method that isn't called is tagged unused but a public method requires more extensive analysis.

If you're using GNU find,

find . -mtime 1 -exec cp -t ~/test/ {} +

This works as well as piping the output into xargs while avoiding the pitfalls of doing so (it handles embedded spaces and newlines without having to use find ... -print0 | xargs -0 ...).

I figured out this answer based on previous solution and it's comment and added some adjustments of my own. This works for me on the responsive table.

table {
  display: inline-block;
  overflow-x: auto;
  white-space: nowrap;
  // make fixed table width effected by overflow-x
  max-width: 100%;
  // hide all borders that make rows not filled with the table width
  border: 0;
}
// add missing borders
table td {
  border: 1px solid;
}

Control Panel > Turn Windows Features on or off

Enable the two options

.NET Extensibility 3.5

This works fine int i = (int) dbl;

use the following code to apply some margin

$(".button").click(function() {
  $('html, body').animate({
    scrollTop: $(".scrolltothis").offset().top + 50;
  }, 500);
});

See this ans: Scroll down to div + a certain margin

If this is nullable int field then yes.

update TableName
set FiledName = null
where Id = SomeId

Personally I prefer the join syntax as its makes it clearer that the tables are joined and how they are joined. Try compare larger SQL queries where you selecting from 8 different tables and you have lots of filtering in the where. By using join syntax you separate out the parts where the tables are joined, to the part where you are filtering the rows.

All you have to do is this

list = ["a", "b", "c"]
    try:
        list.remove("a")
    except:
        print("meow")

but that method has an issue. You have to put something in the except place so i found this:

list = ["a", "b", "c"]
if "a" in str(list):
    list.remove("a")

I just solved this error happening in my tests.

Just make sure your test class has all dependencies in the attributes of the class being tested annotated with @MockBean so SpringBoot test context can wire your classes correctly.

Only if you are testing controller: you need also class annotations to load the Controller context propertly.

Check it out:

@DisplayName("UserController Adapter Test")
@WebMvcTest(UserController.class)
@AutoConfigureMockMvc(addFilters = false)
@Import(TestConfig.class)
public class UserControllerTest {

@Autowired
private MockMvc mockMvc;

@Autowired
private ObjectMapper objectMapper;

@MockBean
private CreateUserCommand createUserCommand;

@MockBean
private GetUserListQuery getUserListQuery;

@MockBean
private GetUserQuery getUserQuery;

One method not yet shown via the XML data() command in MS SQL Server is:

Assume table called NameList with one column called FName,

SELECT FName + ', ' AS 'data()' 
FROM NameList 
FOR XML PATH('')

returns:

"Peter, Paul, Mary, "

Only the extra comma must be dealt with.

Edit: As adopted from @NReilingh's comment, you can use the following method to remove the trailing comma. Assuming the same table and column names:

STUFF(REPLACE((SELECT '#!' + LTRIM(RTRIM(FName)) AS 'data()' FROM NameList
FOR XML PATH('')),' #!',', '), 1, 2, '') as Brands

"... and am finding that my code would be more re-usable if I were able to use variables instead of Select functions."

While I cannot think of any more than an isolated handful of situations where .Select would be a better choice than direct cell referencing, I would rise to the defense of Selection and point out that it should not be thrown out for the same reasons that .Select should be avoided.

There are times when having short, time-saving macro sub routines assigned to hot-key combinations available with the tap of a couple of keys saves a lot of time. Being able to select a group of cells to enact the operational code on works wonders when dealing with pocketed data that does not conform to a worksheet-wide data format. Much in the same way that you might select a group of cells and apply a format change, selecting a group of cells to run special macro code against can be a major time saver.

Examples of Selection-based sub framework:

Public Sub Run_on_Selected()
    Dim rng As Range, rSEL As Range
    Set rSEL = Selection    'store the current selection in case it changes
    For Each rng In rSEL
        Debug.Print rng.Address(0, 0)
        'cell-by-cell operational code here
    Next rng
    Set rSEL = Nothing
End Sub

Public Sub Run_on_Selected_Visible()
    'this is better for selected ranges on filtered data or containing hidden rows/columns
    Dim rng As Range, rSEL As Range
    Set rSEL = Selection    'store the current selection in case it changes
    For Each rng In rSEL.SpecialCells(xlCellTypeVisible)
        Debug.Print rng.Address(0, 0)
        'cell-by-cell operational code here
    Next rng
    Set rSEL = Nothing
End Sub

Public Sub Run_on_Discontiguous_Area()
    'this is better for selected ranges of discontiguous areas
    Dim ara As Range, rng As Range, rSEL As Range
    Set rSEL = Selection    'store the current selection in case it changes
    For Each ara In rSEL.Areas
        Debug.Print ara.Address(0, 0)
        'cell group operational code here
        For Each rng In ara.Areas
            Debug.Print rng.Address(0, 0)
            'cell-by-cell operational code here
        Next rng
    Next ara
    Set rSEL = Nothing
End Sub

The actual code to process could be anything from a single line to multiple modules. I have used this method to initiate long running routines on a ragged selection of cells containing the filenames of external workbooks.

In short, don't discard Selection due to its close association with .Select and ActiveCell. As a worksheet property it has many other purposes.

_{(Yes, I know this question was about .Select, not Selection but I wanted to remove any misconceptions that novice VBA coders might infer.)}

For the 24-hour time, you need to use HH24 instead of HH.

For the 12-hour time, the AM/PM indicator is written as A.M. (if you want periods in the result) or AM (if you don't). For example:

SELECT invoice_date,
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH24:MI:SS') "Date 24Hr",
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH:MI:SS AM') "Date 12Hr"
  FROM invoices
;

For more information on the format models you can use with TO_CHAR on a date, see http://docs.oracle.com/cd/E16655_01/server.121/e17750/ch4datetime.htm#NLSPG004.

After hours of searching and trying I found out that on a x64 server the MSOnline modules must be installed for x64, and some programs that need to run them are using the x86 PS version, so they will never find it.

[SOLUTION] What I did to solve the issue was:

Copy the folders called MSOnline and MSOnline Extended from the source

C:\Windows\System32\WindowsPowerShell\v1.0\Modules\

to the folder

C:\Windows\SysWOW64\WindowsPowerShell\v1.0\Modules\

And then in PS run the Import-Module MSOnline, and it will automatically get the module :D

If your goal is simply to iterate over the range of values for read-only purposes, an alternative is to wrap both vectors around a proxy (O(1)) instead of copying them (O(n)), so they are promptly seen as a single, contiguous one.

std::vector<int> A{ 1, 2, 3, 4, 5};
std::vector<int> B{ 10, 20, 30 };

VecProxy<int> AB(A, B);  // ----> O(1)!

for (size_t i = 0; i < AB.size(); i++)
    std::cout << AB[i] << " ";  // ----> 1 2 3 4 5 10 20 30

Refer to https://stackoverflow.com/a/55838758/2379625 for more details, including the 'VecProxy' implementation as well as pros & cons.

To get a list of all the keys minus _id, consider running the following aggregate pipeline:

var keys = db.collection.aggregate([
    { "$project": {
       "hashmaps": { "$objectToArray": "$$ROOT" } 
    } }, 
    { "$project": {
       "fields": "$hashmaps.k"
    } },
    { "$group": {
        "_id": null,
        "fields": { "$addToSet": "$fields" }
    } },
    { "$project": {
            "keys": {
                "$setDifference": [
                    {
                        "$reduce": {
                            "input": "$fields",
                            "initialValue": [],
                            "in": { "$setUnion" : ["$$value", "$$this"] }
                        }
                    },
                    ["_id"]
                ]
            }
        }
    }
]).toArray()[0]["keys"];

There are several problems here:

1. The newdata argument of predict() needs a predictor variable. You should thus pass it values for Coupon, instead of Total, which is the response variable in your model.

2. The predictor variable needs to be passed in as a named column in a data frame, so that predict() knows what the numbers its been handed represent. (The need for this becomes clear when you consider more complicated models, having more than one predictor variable).

3. For this to work, your original call should pass df in through the data argument, rather than using it directly in your formula. (This way, the name of the column in newdata will be able to match the name on the RHS of the formula).

With those changes incorporated, this will work:

model <- lm(Total ~ Coupon, data=df)
new <- data.frame(Coupon = df$Coupon)
predict(model, newdata = new, interval="confidence")

The same problem happened to me today.

My solution:

Download the latest stable release of chromedriver: https://sites.google.com/a/chromium.org/chromedriver/

Update the chrome driver on your Selenium folder. This is a bit hard, because is in a hidden folder on your PC called AppData. Here is how I did it in my computer (Windows 7):

C: > users > your user > \AppData (you need to write this in the folder path box, since it is a hidden folder) > Local (this is the folder name in portuguese, maybe it will have a different name for you) > SeleniumBasic

There you will find the chromedriver application. Just rename it (in case it does not work, you want to have the older version) and than paste the newest release.

This is just for the record since I bumped into this post when looking for a solution to my problem which was similar to the OP's.

In my case my jQuery Ajax request was prevented from succeeding due to same-origin policy in Chrome. All was resolved when I modified my server (Node.js) to do:

response.writeHead(200,
          {
            "Content-Type": "application/json",
            "Access-Control-Allow-Origin": "http://localhost:8080"
        });

It literally cost me an hour of banging my head against the wall. I am feeling stupid...

You can check that theHref is defined by checking against undefined.

if (undefined !== theHref && theHref.length) {
    // `theHref` is not undefined and has truthy property _length_
    // do stuff
} else {
    // do other stuff
}

If you want to also protect yourself against falsey values like null then check theHref is truthy, which is a little shorter

if (theHref && theHref.length) {
    // `theHref` is truthy and has truthy property _length_
}

I always initialise them as NULL.

I always use string.IsNullOrEmpty(someString) to check it's value.

Simple.

Another good option if you have too much log and you want to only put as a temporal System.out.println(), you can, depending on your provider do:

CriteriaBuilder criteriaBuilder = getEntityManager().getCriteriaBuilder();
CriteriaQuery<ExaminationType> criteriaQuery = criteriaBuilder.createQuery(getEntityClass()); 

/* For Hibernate */
System.out.println(getEntityManager().createQuery(criteriaQuery).unwrap(org.hibernate.query.Query.class).getQueryString());

/* For OpenJPA */ 
System.out.println(getEntityManager().createQuery(criteriaQuery).unwrap(org.apache.openjpa.persistence.QueryImpl.class).getQueryString());

/* For EclipseLink */
System.out.println(getEntityManager().createQuery(criteriaQuery).unwrap(JpaQuery.class).getSQLString());

If your using a background resource and wish to change the resource out you can use setBackgroundResource() function.

ui_item.setBackgroundResource(R.drawable.myResource)

A background resource in XML would look like:

<LinearLayout
                android:id="@+id/ui_item"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="@drawable/background_01"
                android:orientation="vertical">

Instead of launching the batch directly from explorer - create a shortcut to the batch and set the starting directory in the properties of the shortcut to a local path like %TEMP% or something.

To delete the symbolic link, use the rmdir command.

I think you've pretty much nailed the points!

If you follow database design best practices and your primary key is never updatable (which I think should always be the case anyway), then you never really need the ON UPDATE CASCADE clause.

Zed made a good point, that if you use a natural key (e.g. a regular field from your database table) as your primary key, then there might be certain situations where you need to update your primary keys. Another recent example would be the ISBN (International Standard Book Numbers) which changed from 10 to 13 digits+characters not too long ago.

This is not the case if you choose to use surrogate (e.g. artifically system-generated) keys as your primary key (which would be my preferred choice in all but the most rare occasions).

So in the end: if your primary key never changes, then you never need the ON UPDATE CASCADE clause.

Please never do this in real projects:

document.getElementById("span").innerHTML = "String".fontsize(25);

<span id="span"></span>

If you are injecting something that needs the script tag, you may get an uncaught syntax error and say illegal token. To avoid this, be sure to escape the forward slashes in your closing script tag(s). ie;

var output += '<\/script>';

Same goes for any closing tags, such as a form tag.

I don't think that notation is available because—unlike say PHP or C—everything in Ruby is an object.

Sure you could use $var=0; $var++ in PHP, but that's because it's a variable and not an object. Therefore, $var = new stdClass(); $var++ would probably throw an error.

I'm not a Ruby or RoR programmer, so I'm sure someone can verify the above or rectify it if it's inaccurate.

require 'date'

date = DateTime.parse("2011-05-19 10:30:14")
formatted_date = date.strftime('%a %b %d %H:%M:%S %Z %Y')

See strftime() for more information about formatting dates.

I've had to work around this issue and once came up with a pretty complete and scalable solution working for IE6, 7 and 8 (and compatible with other browsers obviously). I've written a whole article about it right here: http://www.edgeoftheworld.fr/wp/work/dealing-with-fixed-sized-dropdown-lists-in-internet-explorer

Thought I'd share this for people who are still running into this problem, as none of the above solutions work in every case (in my opinion).

You cannot select on specific values (or types of values). You'd either make a reverse index (map numbers back to (lists of) keys) or you have to loop through all values every time.

If you are processing numbers in arbitrary order anyway, you may as well loop through all items:

for key, value in inputdict.items():
    # do something with value
    inputdict[key] = newvalue

otherwise I'd go with the reverse index:

from collections import defaultdict

reverse = defaultdict(list)
for key, value in inputdict.items():
    reverse[value].append(key)

Now you can look up keys by value:

for key in reverse[value]:
    inputdict[key] = newvalue

var data=[];
var $el=$("#my-select");
$el.find('option:selected').each(function(){
    data.push({value:$(this).val(),text:$(this).text()});
});
console.log(data)

If the class does not have toString() method, then you can use ToStringBuilder class from org.apache.commons:commons-lang3

pom.xml:

<dependency>
  <groupId>org.apache.commons</groupId>
  <artifactId>commons-lang3</artifactId>
  <version>3.10</version>
</dependency>

code:

ToStringBuilder.reflectionToString(yourObject)

UPDATE for v1.1:

Rather than giving q="search_string" give it q="hashtag" in URL encoded form to return results with HASHTAG ONLY. So your query would become:

    GET https://api.twitter.com/1.1/search/tweets.json?q=%23freebandnames

%23 is URL encoded form of #. Try the link out in your browser and it should work.

You can optimize the query by adding since_id and max_id parameters detailed here. Hope this helps !

Note: Search API is now a OAUTH authenticated call, so please include your access_tokens to the above call

The recent talk by Dav Glass Welcome to the Jungle! (YUIConf 2011 Opening Keynote) shows how you can use YUI 3 on Node.js to do clientside-like programming (with DOM selectors instead of string processing) on the server. It is very impressive.

Here is a great article, You can implement common library and just use below code to import any HTML files in one line.

<head>
   <link rel="import" href="warnings.html">

You can also try Google Polymer

Single quotes are used to indicate the beginning and end of a string in SQL. Double quotes generally aren't used in SQL, but that can vary from database to database.

Stick to using single quotes.

That's the primary use anyway. You can use single quotes for a column alias — where you want the column name you reference in your application code to be something other than what the column is actually called in the database. For example: PRODUCT.id would be more readable as product_id, so you use either of the following:

• SELECT PRODUCT.id AS product_id
• SELECT PRODUCT.id 'product_id'

Either works in Oracle, SQL Server, MySQL… but I know some have said that the TOAD IDE seems to give some grief when using the single quotes approach.

You do have to use single quotes when the column alias includes a space character, e.g., product id, but it's not recommended practice for a column alias to be more than one word.

Both if (one.length() > 0) {} and if (!"".equals(one)) {} will check against an empty foo parameter, and an empty parameter is what you'd get if the the form is submitted with no value in the foo text field.

If there's any chance you can use the Expression Language to handle the parameter, you could access it with empty param.foo in an expression.

<c:if test='${not empty param.foo}'>
    This page code gets rendered.
</c:if>

You can use pandas methods where and mask:

df['color'] = 'green'
df['color'] = df['color'].where(df['Set']=='Z', other='red')
# Replace values where the condition is False

or

df['color'] = 'red'
df['color'] = df['color'].mask(df['Set']=='Z', other='green')
# Replace values where the condition is True

Output:

  Type Set  color
1    A   Z  green
2    B   Z  green
3    B   X    red
4    C   Y    red

you can write events on elements like chain,

$(element).on('click',function(){
   //action on click
}).on('mouseup',function(){
   //action on mouseup (just before click event)
});

i've used it for removing cart items. same object, doing some action, after another action

Add the framework required for the method used in the project target in the "Link Binaries With Libraries" list of Build Phases, it will work easily. Like I have imported to my project

You can use Batch update but queries must be action(i.e. insert,update and delete) queries

Statement s = c.createStatement();
String s1 = "update emp set name='abc' where salary=984";
String s2 = "insert into emp values ('Osama',1420)";  
s.addBatch(s1);
s.addBatch(s2);     
s.executeBatch();

The simplest code to align the iframe element:

<div align="center"><iframe width="560" height="315" src="www.youtube.com" frameborder="1px"></iframe></div>

If you just want to use AWT, then use Graphics.getFontMetrics (optionally specifying the font, for a non-default one) to get a FontMetrics and then FontMetrics.stringWidth to find the width for the specified string.

For example, if you have a Graphics variable called g, you'd use:

int width = g.getFontMetrics().stringWidth(text);

For other toolkits, you'll need to give us more information - it's always going to be toolkit-dependent.

Try like this: server.bind(("0.0.0.0", 6677))

If you don't want the text-to-be-coppied to be visible:

jQuery:

$('button.copyButton').click(function(){
    $(this).siblings('input.linkToCopy').select();      
    document.execCommand("copy");
});

HTML:

<button class="copyButton">click here to copy</button>
<input class="linkToCopy" value="TEXT TO COPY"
style="position: absolute; z-index: -999; opacity: 0;" />

Counting the number of lines can be done by following codes:

<?php
$fp= fopen("myfile.txt", "r");
$count=0;
while($line = fgetss($fp)) // fgetss() is used to get a line from a file ignoring html tags
$count++;
echo "Total number of lines  are ".$count;
fclose($fp);
?>

SET

SET @var_name = value 

OR

SET @var := value

both operators = and := are accepted

SELECT

SELECT col1, @var_name := col2 from tb_name WHERE "conditon";

if multiple record sets found only the last value in col2 is keep (override);

SELECT col1, col2 INTO @var_name, col3 FROM .....

in this case the result of select is not containing col2 values

Ex both methods used

• A worker process runs as an executables file named W3wp.exe

• A Worker Process is user mode code whose role is to process requests, such as processing requests to return a static page.

• The worker process is controlled by the www service.

• worker processes also run application code, Such as ASP .NET applications and XML web Services.

• When Application pool receive the request, it simply pass the request to worker process (w3wp.exe) . The worker process“w3wp.exe” looks up the URL of the request in order to load the correct ISAPI extension. ISAPI extensions are the IIS way to handle requests for different resources. Once ASP.NET is installed, it installs its own ISAPI extension (aspnet_isapi.dll)and adds the mapping into IIS.

• When Worker process loads the aspnet_isapi.dll, it start an HTTPRuntime, which is the entry point of an application. HTTPRuntime is a class which calls the ProcessRequest method to start Processing.

For more detail refer URL http://aspnetnova.blogspot.in/2011/12/how-iis-process-for-aspnet-requests.html

To add another alternative to tuple(l), as of Python >= 3.5 you can do:

t = *l,  # or t = (*l,) 

short, a bit faster but probably suffers from readability.

This essentially unpacks the list l inside a tuple literal which is created due to the presence of the single comma ,.

P.s: The error you are receiving is due to masking of the name tuple i.e you assigned to the name tuple somewhere e.g tuple = (1, 2, 3).

Using del tuple you should be good to go.

Simple solution :

private boolean stringNotEmptyOrNull(String st) {
    return st != null && !st.isEmpty();
}

EDIT (02 Jan 2012):

I created a small open source Android Library Project that streamlines this process, while also providing a built-in file explorer (in case the user does not have one present). It's extremely simple to use, requiring only a few lines of code.

You can find it at GitHub: aFileChooser.

ORIGINAL

If you want the user to be able to choose any file in the system, you will need to include your own file manager, or advise the user to download one. I believe the best you can do is look for "openable" content in an Intent.createChooser() like this:

private static final int FILE_SELECT_CODE = 0;

private void showFileChooser() {
    Intent intent = new Intent(Intent.ACTION_GET_CONTENT); 
    intent.setType("*/*"); 
    intent.addCategory(Intent.CATEGORY_OPENABLE);

    try {
        startActivityForResult(
                Intent.createChooser(intent, "Select a File to Upload"),
                FILE_SELECT_CODE);
    } catch (android.content.ActivityNotFoundException ex) {
        // Potentially direct the user to the Market with a Dialog
        Toast.makeText(this, "Please install a File Manager.", 
                Toast.LENGTH_SHORT).show();
    }
}

You would then listen for the selected file's Uri in onActivityResult() like so:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    switch (requestCode) {
        case FILE_SELECT_CODE:
        if (resultCode == RESULT_OK) {
            // Get the Uri of the selected file 
            Uri uri = data.getData();
            Log.d(TAG, "File Uri: " + uri.toString());
            // Get the path
            String path = FileUtils.getPath(this, uri);
            Log.d(TAG, "File Path: " + path);
            // Get the file instance
            // File file = new File(path);
            // Initiate the upload
        }
        break;
    }
    super.onActivityResult(requestCode, resultCode, data);
}

The getPath() method in my FileUtils.java is:

public static String getPath(Context context, Uri uri) throws URISyntaxException {
    if ("content".equalsIgnoreCase(uri.getScheme())) {
        String[] projection = { "_data" };
        Cursor cursor = null;

        try {
            cursor = context.getContentResolver().query(uri, projection, null, null, null);
            int column_index = cursor.getColumnIndexOrThrow("_data");
            if (cursor.moveToFirst()) {
                return cursor.getString(column_index);
            }
        } catch (Exception e) {
            // Eat it
        }
    }
    else if ("file".equalsIgnoreCase(uri.getScheme())) {
        return uri.getPath();
    }

    return null;
} 

Yes, to some degree as detailed here.
The approach I've used (pre-2008) is to do the conversion in the .NET business logic before inserting into the DB.

data-target is used by bootstrap to make your life easier. You (mostly) do not need to write a single line of Javascript to use their pre-made JavaScript components.

The data-target attribute should contain a CSS selector that points to the HTML Element that will be changed.

Modal Example Code from BS3:

<!-- Button trigger modal -->
<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
  Launch demo modal
</button>

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  [...]
</div>

In this example, the button has data-target="#myModal", if you click on it, <div id="myModal">...</div> will be modified (in this case faded in). This happens because #myModal in CSS selectors points to elements that have an id attribute with the myModal value.

Further information about the HTML5 "data-" attribute: https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Using_data_attributes

Starting with the following sample data :

df <- data.frame(v1=letters[1:5],v2=1:5,v3=letters[10:14],stringsAsFactors=FALSE)

  v1 v2 v3
1  a  1  j
2  b  2  k
3  c  3  l
4  d  4  m
5  e  5  n

You can use :

data.frame(lapply(df, function(v) {
  if (is.character(v)) return(toupper(v))
  else return(v)
}))

Which gives :

  v1 v2 v3
1  A  1  J
2  B  2  K
3  C  3  L
4  D  4  M
5  E  5  N

Tooltip plugin might be too heavyweight for what you need. Simply set the 'title' attribute with the text you desire to show in your tooltip.

$("#yourElement").attr('title', 'This is the hover-over text');

maybe ZSI which implements SOAP. I used the stub generator and It worked properly. The only problem I encountered is about doing SOAP throught HTTPS.

$sql = "SELECT * FROM table_name ORDER BY ID DESC LIMIT 1";
$records = mysql_query($sql);

you can change LIMIT 1 to LIMIT any number you want

This will show you the last INSERTED row first.

According to the site I'll post below, it's all how you set up your server. One example they show is this:

var http = require("http");
var url = require("url");

function start(route, handle) {
  function onRequest(request, response) {
    var pathname = url.parse(request.url).pathname;
    console.log("Request for " + pathname + " received.");

    route(handle, pathname, response);
  }

  http.createServer(onRequest).listen(8888);
  console.log("Server has started.");
}

exports.start = start;

and their route function:

function route(handle, pathname, response) {
  console.log("About to route a request for " + pathname);
  if (typeof handle[pathname] === 'function') {
    handle[pathname](response);
  } else {
    console.log("No request handler found for " + pathname);
    response.writeHead(404, {"Content-Type": "text/plain"});
    response.write("404 Not found");
    response.end();
  }
}

exports.route = route;

This is one way. http://www.nodebeginner.org/

From another site, they create a page and then load it. This might be more of what you're looking for.

fs.readFile('www/404.html', function(error2, data) {
            response.writeHead(404, {'content-type': 'text/html'});
            response.end(data);
        });

Here's my code (not optimized but a full working example):

<head>
<style>
#divtoshow {position:absolute;display:none;color:white;background-color:black}
#onme {width:150px;height:80px;background-color:yellow;cursor:pointer}
</style>
<script type="text/javascript">
var divName = 'divtoshow'; // div that is to follow the mouse (must be position:absolute)
var offX = 15;          // X offset from mouse position
var offY = 15;          // Y offset from mouse position

function mouseX(evt) {if (!evt) evt = window.event; if (evt.pageX) return evt.pageX; else if (evt.clientX)return evt.clientX + (document.documentElement.scrollLeft ?  document.documentElement.scrollLeft : document.body.scrollLeft); else return 0;}
function mouseY(evt) {if (!evt) evt = window.event; if (evt.pageY) return evt.pageY; else if (evt.clientY)return evt.clientY + (document.documentElement.scrollTop ? document.documentElement.scrollTop : document.body.scrollTop); else return 0;}

function follow(evt) {
    var obj = document.getElementById(divName).style;
    obj.left = (parseInt(mouseX(evt))+offX) + 'px';
    obj.top = (parseInt(mouseY(evt))+offY) + 'px'; 
    }
document.onmousemove = follow;
</script>
</head>
<body>
<div id="divtoshow">test</div>
<br><br>
<div id='onme' onMouseover='document.getElementById(divName).style.display="block"' onMouseout='document.getElementById(divName).style.display="none"'>Mouse over this</div>
</body>

C++11:

std::map< std::string, std::map<std::string, std::string> > m;
m["name1"]["value1"] = "data1";
m["name1"]["value2"] = "data2";
m["name2"]["value1"] = "data1";
m["name2"]["value2"] = "data2";
m["name3"]["value1"] = "data1";
m["name3"]["value2"] = "data2";

for (auto i : m)
    for (auto j : i.second)
        cout << i.first.c_str() << ":" << j.first.c_str() << ":" << j.second.c_str() << endl;

output:

name1:value1:data1
name1:value2:data2
name2:value1:data1
name2:value2:data2
name3:value1:data1
name3:value2:data2

To see the window height while (or after) it is resized, try it:

$(window).resize(function() {
$('body').prepend('<div>' + $(window).height() - 46 + '</div>');
});

It's impossible to draw a line on screen that's thinner than one pixel. Try using a more subtle color for the border instead.

For substracting in moment.js:

moment().subtract(1, 'months').format('MMM YYYY');

Documentation:

http://momentjs.com/docs/#/manipulating/subtract/

Before version 2.8.0, the moment#subtract(String, Number) syntax was also supported. It has been deprecated in favor of moment#subtract(Number, String).

  moment().subtract('seconds', 1); // Deprecated in 2.8.0
  moment().subtract(1, 'seconds');

As of 2.12.0 when decimal values are passed for days and months, they are rounded to the nearest integer. Weeks, quarters, and years are converted to days or months, and then rounded to the nearest integer.

  moment().subtract(1.5, 'months') == moment().subtract(2, 'months')
  moment().subtract(.7, 'years') == moment().subtract(8, 'months') //.7*12 = 8.4, rounded to 8

You can just multiply 1.0

>>> 1.0*144/314

I realize this is an old question and has been answered but this could help someone. In your activity

private ScheduledExecutorService scheduleTaskExecutor;

In onCreate

  scheduleTaskExecutor = Executors.newScheduledThreadPool(5);

    //Schedule a task to run every 5 seconds (or however long you want)
    scheduleTaskExecutor.scheduleAtFixedRate(new Runnable() {
        @Override
        public void run() {
            // Do stuff here!

            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    // Do stuff to update UI here!
                    Toast.makeText(MainActivity.this, "Its been 5 seconds", Toast.LENGTH_SHORT).show();
                }
            });

        }
    }, 0, 5, TimeUnit.SECONDS); // or .MINUTES, .HOURS etc.

Intellij had .ignore plugin to support this. https://plugins.jetbrains.com/plugin/7495?pr=idea

After you install the plugin, you right click on the project and select new -> .ignore file -> .gitignore file (Git)

Then, select the type of project you have to generate a template and click Generate.

The getChars string method does not return a value, instead it dumps its result into your buffer (or destination) array. The index parameter describes the start offset in your destination array.

Try this link for a more verbose description of the getChars method.

I agree with the others on this, I think substring would be a better way to handle what you're trying to accomplish.

I rely on NDEBUG, because it's the only one whose behavior is standardized across compilers and implementations (see documentation for the standard assert macro). The negative logic is a small readability speedbump, but it's a common idiom you can quickly adapt to.

To rely on something like _DEBUG would be to rely on an implementation detail of a particular compiler and library implementation. Other compilers may or may not choose the same convention.

The third option is to define your own macro for your project, which is quite reasonable. Having your own macro gives you portability across implementations and it allows you to enable or disable your debugging code independently of the assertions. Though, in general, I advise against having different classes of debugging information that are enabled at compile time, as it causes an increase in the number of configurations you have to build (and test) for arguably small benefit.

With any of these options, if you use third party code as part of your project, you'll have to be aware of which convention it uses.

Another option is just using head:

grep ...parameters... yourfile | head

This won't require searching the entire file - it will stop when the first ten matching lines are found. Another advantage with this approach is that will return no more than 10 lines even if you are using grep with the -o option.

For example if the file contains the following lines:

112233
223344
123123

Then this is the difference in the output:

$ grep -o '1.' yourfile | head -n2
11
12

$ grep -m2 -o '1.'
11
12
12

Using head returns only 2 results as desired, whereas -m2 returns 3.

I had this issue when I was using homebrew. Here is the solution from Issue #26900

python -m pip install --upgrade --force pip

In my case the solution was to remove the attribute

validationQuery="select 1"

from the (Derby DB) resource tag.

scp -i /home/<user>/.ssh/id_rsa -o "StrictHostKeyChecking=no" -rp /source/directory/path/[!.]* <target_user>@<target_system:/destination/directory/path

It really depends on the kind of classes as not all classes are created equal.

As general guideline I would suggest 2 options:

• For value & immutable classes (Exception, Integer, DTOs and such) use single primary constructor as suggested in above answer
• For everything else (session beans, services, mutable objects, JPA & JAXB entities and so on) use default constructor only with sensible defaults on all the properties so it can be used without additional configuration

Since this must have an input element as a parent, you could just use

<input type="text" ng-model="foo" ng-change="myOnChangeFunction()">

Alternatively, you could use the ngModelController and add a function to $formatters, which executes functions on input change. See http://docs.angularjs.org/api/ng.directive:ngModel.NgModelController

.directive("myDirective", function() {
  return {
    restrict: 'A',
    require: 'ngModel',
    link: function(scope, element, attr, ngModel) {
      ngModel.$formatters.push(function(value) {
        // Do stuff here, and return the formatted value.
      });
  };
};

I'm quite ashamed that there are so many incorrect or undisclosed partial applicability.

The easiest way to do this is through Chrome or Opera (my examples will use Chrome) using the Console. Enter the following code into the console (generally in 1 line):

var l = document.getElementById('testLink');
for(var i=0; i<5; i++){
  l.click();
}

This will generate the required result

SELECT * FROM MyTable WHERE Column1 Like "*word*"

This will display all the records where column1 has a partial value contains word.

I don't know for sure if the solution is safe, but about the ClassGuard solution, it's interesting to read the article and the comment at: http://www.javaworld.com/community/?q=node/1604#comment-12296

Another alternative:

head -$((${RANDOM} % `wc -l < file` + 1)) file | tail -1

You can specify a formatter and use lstart, like this command:

ps -eo pid,lstart,cmd

The above command will output all processes, with formatters to get PID, command run, and date+time started.

Example (from Debian/Jessie command line)

$ ps -eo pid,lstart,cmd
  PID CMD                                          STARTED

I have used graphviz ( https://www.graphviz.org/gallery ) together with LaTeX using dot command to generate graphs in PDF and includegraphics to include those.

If graphviz produces what you are aiming at, this might be the best way to integrate: dot2tex: https://ctan.org/pkg/dot2tex?lang=en

You need to

set identity_insert YourTable ON

Then delete your row and reinsert it with different identity.

Once you have done the insert don't forget to turn identity_insert off

set identity_insert YourTable OFF

And, of course

 ("ABCD"[2] == 2["ABCD"]) && (2["ABCD"] == 'C') && ("ABCD"[2] == 'C')

The main reason for this was that back in the 70's when C was designed, computers didn't have much memory (64KB was a lot), so the C compiler didn't do much syntax checking. Hence "X[Y]" was rather blindly translated into "*(X+Y)"

This also explains the "+=" and "++" syntaxes. Everything in the form "A = B + C" had the same compiled form. But, if B was the same object as A, then an assembly level optimization was available. But the compiler wasn't bright enough to recognize it, so the developer had to (A += C). Similarly, if C was 1, a different assembly level optimization was available, and again the developer had to make it explicit, because the compiler didn't recognize it. (More recently compilers do, so those syntaxes are largely unnecessary these days)

You may use this :

Download "angular-post-fix": "^0.1.0"

Then add 'httpPostFix' to your dependencies while declaring the angular module.

If the files already have the +x flag set, git update-index --chmod=+x does nothing and git thinks there's nothing to commit, even though the flag isn't being saved into the repo.

You must first remove the flag, run the git command, then put the flag back:

chmod -x <file>
git update-index --chmod=+x <file>
chmod +x <file>

then git sees a change and will allow you to commit the change.

The easiest way to match both

^\([0-9]{3}\)[0-9]{3}-[0-9]{4}$

and

^[0-9]{3}-[0-9]{3}-[0-9]{4}$

is to use alternation ((...|...)): specify them as two mostly-separate options:

^(\([0-9]{3}\)|[0-9]{3}-)[0-9]{3}-[0-9]{4}$

By the way, when Americans put the area code in parentheses, we actually put a space after that; for example, I'd write (123) 123-1234, not (123)123-1234. So you might want to write:

^(\([0-9]{3}\) |[0-9]{3}-)[0-9]{3}-[0-9]{4}$

(Though it's probably best to explicitly demonstrate the format that you expect phone numbers to be in.)

Docker can build images automatically by reading the instructions from a Dockerfile. A Dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image. example: FROM python:3.7-alpine The 'python' should be in lowercase

For Python 3xx:

import time
for i in range(10):
    time.sleep(0.2) 
    print ("\r Loading... {}".format(i)+str(i), end="")

It's very simple,

listViewRequests.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                    **AppCompatCheckedTextView checkBox = (AppCompatCheckedTextView) view;**
                    Log.i("CHECK",checkBox.isChecked()+""+checkBox.getText().toString());**

               }
            });

Maybe you forgot the await before returning your collection

Try casting the ints to varchar, before adding them to a string:

SET @ActualWeightDIMS = cast(@Actual_Dims_Lenght as varchar(8)) + 
   'x' + cast(@Actual_Dims_Width as varchar(8)) + 
   'x' + cast(@Actual_Dims_Height as varhcar(8))

foreach (var data in dynObj.quizlist)
{
    foreach (var data1 in data.QUIZ.QPROP)
    {
        Response.Write("Name" + ":" + data1.name + "<br>");
        Response.Write("Intro" + ":" + data1.intro + "<br>");
        Response.Write("Timeopen" + ":" + data1.timeopen + "<br>");
        Response.Write("Timeclose" + ":" + data1.timeclose + "<br>");
        Response.Write("Timelimit" + ":" + data1.timelimit + "<br>");
        Response.Write("Noofques" + ":" + data1.noofques + "<br>");

        foreach (var queprop in data1.QUESTION.QUEPROP)
        {
            Response.Write("Questiontext" + ":" + queprop.questiontext  + "<br>");
            Response.Write("Mark" + ":" + queprop.mark  + "<br>");
        }
    }
}

Though this is old, I'm updating it for others who might find this question when searching later.

@Matt Kelliher:

Using the css :before and a data-* attribute for the list is a great idea, but can be modified slightly to be more handicap accessible as well:

HTML:

<ul aria-label="Vehicle Models Available:"> 
    <li>Dodge Shadow</li>
    <li>Ford Focus</li>
    <li>Chevy Lumina</li>
</ul>

CSS:

ul:before{
    content:attr(aria-label);
    font-size:120%;
    font-weight:bold;
    margin-left:-15px;
}

This will make a list with the "header" pseudo element above it with text set to the value in the aria-label attribute. You can then easily style it to your needs.

The benefit of this over using a data-* attribute is that aria-label will be read off by screen readers as a "label" for the list, which is semantically correct for your intended use of this data.

Note: IE8 supports :before attributes, but must use the single colon version (and must have a valid doctype defined). IE7 does not support :before, but Modernizer or Selectivizr should fix that issue for you. All modern browsers support the older :before syntax, but prefer that the ::before syntax be used. Generally the best way to handle this is to have an external stylesheet for IE7/8 that uses the old format and a general stylesheet using the new format, but in practice, most just use the old single colon format since it is still 100% cross browser, even if not technically valid for CSS3.

You can loop through a hash map like this

<%
ArrayList list = new ArrayList();
TreeMap itemList=new TreeMap();
itemList.put("test", "test");
list.add(itemList);
pageContext.setAttribute("itemList", list);                            
%>

  <c:forEach items="${itemList}" var="itemrow">
   <input  type="text"  value="<c:out value='${itemrow.test}'/>"/>
  </c:forEach>

A stemmer is supposed to turn inflected forms of words down to some common root. It's not really a stemmer's job to make that root a 'proper' dictionary word. For that you need to look at morphological/orthographic analysers.

I think this question is about more or less the same thing, and Kaarel's answer to that question is where I took the second link from.

Netcat sends one packet per newline. So you're fine. If you do anything more complex then you might need something else.

I was fooling around with Wireshark when I realized this. Don't know if it helps.

JavaScript Serializer: requires using System.Web.Script.Serialization;

public class JavaScriptSerializerDeSerializer<T>
{
    private readonly JavaScriptSerializer serializer;

    public JavaScriptSerializerDeSerializer()
    {
        this.serializer = new JavaScriptSerializer();
    }

    public string Serialize(T t)
    {
        return this.serializer.Serialize(t);
    }

    public T Deseralize(string stringObject)
    {
        return this.serializer.Deserialize<T>(stringObject);
    }
}

Data Contract Serializer: requires using System.Runtime.Serialization.Json; - The generic type T should be serializable more on Data Contract

public class JsonSerializerDeserializer<T> where T : class
{
    private readonly DataContractJsonSerializer jsonSerializer;

    public JsonSerializerDeserializer()
    {
        this.jsonSerializer = new DataContractJsonSerializer(typeof(T));
    }

    public string Serialize(T t)
    {
        using (var memoryStream = new MemoryStream())
        {
            this.jsonSerializer.WriteObject(memoryStream, t);
            memoryStream.Position = 0;
            using (var sr = new StreamReader(memoryStream))
            {
                return sr.ReadToEnd();
            }
        }
    }

    public T Deserialize(string objectString)
    {
        using (var ms = new MemoryStream(System.Text.ASCIIEncoding.ASCII.GetBytes((objectString))))
        {
            return (T)this.jsonSerializer.ReadObject(ms);
        }
    }

If you just want to detect mobile devices in generel, Cake has build in support using RequestHandler->isMobile() (http://book.cakephp.org/2.0/en/core-libraries/components/request-handling.html#RequestHandlerComponent::isMobile)

1.save your file name as hey.py with the below given hello world script

#! /usr/bin/python
print('Hello, world!')

2.open the terminal in that directory

$ python hey.py

or if you are using python3 then

$ python3 hey.py

Creating a text file in unix can be done through a text editor (vim, emacs, gedit, etc). But what you want might be something like this

echo "insert text here" > myfile.txt

That will put the text 'insert text here' into a file myfile.txt. To verify that this worked use the command 'cat'.

cat myfile.txt

If you want to append to a file use this

echo "append this text" >> myfile.txt

Starting with Java 5.0 you can specify the type of element in the container:

Collections.<Foo>emptyList()

I concur with the other responses that for cases where you want to return an empty list that stays empty, you should use this approach.

Like this:

Set<T> mySet = new HashSet<>(Arrays.asList(someArray));

In Java 9+, if unmodifiable set is ok:

Set<T> mySet = Set.of(someArray);

In Java 10+, the generic type parameter can be inferred from the arrays component type:

var mySet = Set.of(someArray);

The max length of a varchar is subject to the max row size in MySQL, which is 64KB (not counting BLOBs):

VARCHAR(65535)

However, note that the limit is lower if you use a multi-byte character set:

VARCHAR(21844) CHARACTER SET utf8

Here are some examples:

The maximum row size is 65535, but a varchar also includes a byte or two to encode the length of a given string. So you actually can't declare a varchar of the maximum row size, even if it's the only column in the table.

mysql> CREATE TABLE foo ( v VARCHAR(65534) );
ERROR 1118 (42000): Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs

But if we try decreasing lengths, we find the greatest length that works:

mysql> CREATE TABLE foo ( v VARCHAR(65532) );
Query OK, 0 rows affected (0.01 sec)

Now if we try to use a multibyte charset at the table level, we find that it counts each character as multiple bytes. UTF8 strings don't necessarily use multiple bytes per string, but MySQL can't assume you'll restrict all your future inserts to single-byte characters.

mysql> CREATE TABLE foo ( v VARCHAR(65532) ) CHARSET=utf8;
ERROR 1074 (42000): Column length too big for column 'v' (max = 21845); use BLOB or TEXT instead

In spite of what the last error told us, InnoDB still doesn't like a length of 21845.

mysql> CREATE TABLE foo ( v VARCHAR(21845) ) CHARSET=utf8;
ERROR 1118 (42000): Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs

This makes perfect sense, if you calculate that 21845*3 = 65535, which wouldn't have worked anyway. Whereas 21844*3 = 65532, which does work.

mysql> CREATE TABLE foo ( v VARCHAR(21844) ) CHARSET=utf8;
Query OK, 0 rows affected (0.32 sec)

Try this

String[] arr = list.toArray(new String[list.size()]);

In the PHP version you can send 'true' in the last parameter, but the default is 'false'. The following algorithm is equivalent to the default PHP's hash function when passing 'sha256' as the first parameter:

public static string GetSha256FromString(string strData)
    {
        var message = Encoding.ASCII.GetBytes(strData);
        SHA256Managed hashString = new SHA256Managed();
        string hex = "";

        var hashValue = hashString.ComputeHash(message);
        foreach (byte x in hashValue)
        {
            hex += String.Format("{0:x2}", x);
        }
        return hex;
    }

Short explanation:

If an algorithm is of T(g(n)), it means that the running time of the algorithm as n (input size) gets larger is proportional to g(n).

If an algorithm is of O(g(n)), it means that the running time of the algorithm as n gets larger is at most proportional to g(n).

Normally, even when people talk about O(g(n)) they actually mean T(g(n)) but technically, there is a difference.

More technically:

O(n) represents upper bound. T(n) means tight bound. O(n) represents lower bound.

f(x) = T(g(x)) iff f(x) = O(g(x)) and f(x) = O(g(x))

Basically when we say an algorithm is of O(n), it's also O(n²), O(n^1000000), O(2ⁿ), ... but a T(n) algorithm is not T(n²).

In fact, since f(n) = T(g(n)) means for sufficiently large values of n, f(n) can be bound within c₁g(n) and c₂g(n) for some values of c₁ and c₂, i.e. the growth rate of f is asymptotically equal to g: g can be a lower bound and and an upper bound of f. This directly implies f can be a lower bound and an upper bound of g as well. Consequently,

f(x) = T(g(x)) iff g(x) = T(f(x))

Similarly, to show f(n) = T(g(n)), it's enough to show g is an upper bound of f (i.e. f(n) = O(g(n))) and f is a lower bound of g (i.e. f(n) = O(g(n)) which is the exact same thing as g(n) = O(f(n))). Concisely,

f(x) = T(g(x)) iff f(x) = O(g(x)) and g(x) = O(f(x))

There are also little-oh and little-omega (?) notations representing loose upper and loose lower bounds of a function.

To summarize:

f(x) = O(g(x)) (big-oh) means that the growth rate of f(x) is asymptotically less than or equal to to the growth rate of g(x).

f(x) = O(g(x)) (big-omega) means that the growth rate of f(x) is asymptotically greater than or equal to the growth rate of g(x)

f(x) = o(g(x)) (little-oh) means that the growth rate of f(x) is asymptotically less than the growth rate of g(x).

f(x) = ?(g(x)) (little-omega) means that the growth rate of f(x) is asymptotically greater than the growth rate of g(x)

f(x) = T(g(x)) (theta) means that the growth rate of f(x) is asymptotically equal to the growth rate of g(x)

For a more detailed discussion, you can read the definition on Wikipedia or consult a classic textbook like Introduction to Algorithms by Cormen et al.

The page sizes are looking different in your PDF because the images were originally set to different DPI (even if images are identical HxW in pixels). The good news is - it's only a display issue - and can be fixed easily.

An image with a higher DPI value would display smaller in a PDF (displays at the 'print-size' of the image). To avoid this, open each image in an image editor like GIMP or Photoshop. Open relevant image print control dialog box and set a suitable uniform DPI info for all the images. Remake the PDF with these new images. If in the new PDF images are too big - redo the DPI setting for each to a higher value. If in the new PDF pages are too small to read on-screen without zooming, again - redo DPI adjustment, this time put a lower DPI value. Ideally, 150 DPI should be good enough for images of 2500X2500 pixel - on a 17 inch monitor set to 1366x768 resolution.

BTW, the PDF file shall print each page at the specified DPI of that page. If all images are same DPI, you'll get a uniform printing.

Hope this helps :)

I was also facing similar issues. I followed below mentioned steps and it worked for me:

• go to Windows > Start > Node.js

  • right click on Node.js command prompt
  • click on Run as administrator

• ping registry.npmjs.org

• npm view npm version

• cd %ProgramFiles%\nodejs

• npm install npm@latest

and npm updated successfully. Earlier I was trying for CMD and that was throwing error. may be some path issue that got resolved by running NodeJs Command Prompt. hope it'll work for you. try this.

This works perfectly as we want:

Unzip files:

find . -name "*.zip" | xargs -P 5 -I FILENAME sh -c 'unzip -o -d "$(dirname "FILENAME")" "FILENAME"'

Above command does not create duplicate directories.

Remove all zip files:

find . -depth -name '*.zip' -exec rm {} \;

If you're not wanting to save changes set savechanges to false

    Sub CloseBook2()
        ActiveWorkbook.Close savechanges:=False
    End Sub

for more examples, http://support.microsoft.com/kb/213428 and i believe in the past I've just used

    ActiveWorkbook.Close False

Here is a LINQ solution which is O(n) with decent constant factors:

int[] anArray = { 1, 5, 2, 7, 1 };

int index = 0;
int maxIndex = 0;

var max = anArray.Aggregate(
    (oldMax, element) => {
        ++index;
        if (element <= oldMax)
            return oldMax;
        maxIndex = index;
        return element;
    }
);

Console.WriteLine("max = {0}, maxIndex = {1}", max, maxIndex);

But you should really write an explicit for lop if you care about performance.

None of the answers worked for me. If you are running on Ubuntu, you can try:

With python3:

sudo apt-get install python3 python-dev python3-dev \
     build-essential libssl-dev libffi-dev \
     libxml2-dev libxslt1-dev zlib1g-dev \
     python-pip

With Python 2:

sudo apt-get install python-dev  \
     build-essential libssl-dev libffi-dev \
     libxml2-dev libxslt1-dev zlib1g-dev \
     python-pip

True you can't have different sized slides. NOT true the size of you slide doesn't matter. It will size it to your resolution, but you can click on the magnifying icon(at least on PP 2013) and you can then scroll in all directions of your slide in original resolution.

Regular expressions are great, but why not just make sure it's a number before trying to do something with it?

function addemup() {
var n1 = document.getElementById("num1");
var n2 = document.getElementById("num2");
sum = Number(n1.value) + Number(n2.value);
    if(Number(sum)) {
        alert(sum);
        } else {
            alert("Numbers only, please!");
        };
    };

I assume you want the DER encoded version of your PEM private key.

openssl rsa -outform der -in private.pem -out private.key

I set up a simple 3-column range on Sheet1 with Country, City, and Language in columns A, B, and C. The following code autofilters the range and then pastes only one of the columns of autofiltered data to another sheet. You should be able to modify this for your purposes:

Sub CopyPartOfFilteredRange()
    Dim src As Worksheet
    Dim tgt As Worksheet
    Dim filterRange As Range
    Dim copyRange As Range
    Dim lastRow As Long

    Set src = ThisWorkbook.Sheets("Sheet1")
    Set tgt = ThisWorkbook.Sheets("Sheet2")

    ' turn off any autofilters that are already set
    src.AutoFilterMode = False

    ' find the last row with data in column A
    lastRow = src.Range("A" & src.Rows.Count).End(xlUp).Row

    ' the range that we are auto-filtering (all columns)
    Set filterRange = src.Range("A1:C" & lastRow)

    ' the range we want to copy (only columns we want to copy)
    ' in this case we are copying country from column A
    ' we set the range to start in row 2 to prevent copying the header
    Set copyRange = src.Range("A2:A" & lastRow)

    ' filter range based on column B
    filterRange.AutoFilter field:=2, Criteria1:="Rio de Janeiro"

    ' copy the visible cells to our target range
    ' note that you can easily find the last populated row on this sheet
    ' if you don't want to over-write your previous results
    copyRange.SpecialCells(xlCellTypeVisible).Copy tgt.Range("A1")

End Sub

Note that by using the syntax above to copy and paste, nothing is selected or activated (which you should always avoid in Excel VBA) and the clipboard is not used. As a result, Application.CutCopyMode = False is not necessary.

Under Windows dont forget to set

SET HTTPS_PROXY=<proxyHost>:<proxyPort>

what I needed to set for

pip install pep8

GET (multiple parameters):

curl -X  GET "http://localhost:3000/action?result1=gh&result2=ghk"

or

curl --request  GET "http://localhost:3000/action?result1=gh&result2=ghk"

or

curl  "http://localhost:3000/action?result1=gh&result2=ghk"

or

curl -i -H "Application/json" -H "Content-type: application/json"  "http://localhost:3000/action?result1=gh&result2=ghk"

PHP arrays are both integer-indexed and string-indexed. You can even mix them:

array('red', 'green', 'white', 'color3'=>'blue', 3=>'yellow');

What do you want the index to be for the value 'blue'? Is it 3? But that's actually the index of the value 'yellow', so that would be an ambiguity.

Another solution for you is to coerce the array to an integer-indexed list of values.

foreach (array_values($array) as $i => $value) {
  echo "$i: $value\n";
}

Output:

0: red
1: green
2: white
3: blue
4: yellow

Use print("use this bracket -sample text")

In Python 3 print "Hello world" gives invalid syntax error.

To display string content in Python3 have to use this ("Hello world") brackets.

The problem you're running into is that most background thread / worker APIs will create the thread in a Multithreaded Apartment state. The error message indicates that the control requires the thread be a Single Threaded Apartment.

You can work around this by creating a thread yourself and specifying the STA apartment state on the thread.

var t = new Thread(MyThreadStartMethod);
t.SetApartmentState(ApartmentState.STA);
t.Start();

SHTML is a file extension that lets the web server know the file should be processed as using Server Side Includes (SSI).

(HTML is...you know what it is, and DHTML is Microsoft's name for Javascript+HTML+CSS or something).

You can use SSI to include a common header and footer in your pages, so you don't have to repeat code as much. Changing one included file updates all of your pages at once. You just put it in your HTML page as per normal.

It's embedded in a standard XML comment, and looks like this:

<!--#include virtual="top.shtml" -->

It's been largely superseded by other mechanisms, such as PHP includes, but some hosting packages still support it and nothing else.

You can read more in this Wikipedia article.

AND, if you just want to get a count of all the rows in a table

$table_row_count = $this->db->count_all('table_name');

This solved my problem:

git clone --depth=20 https://repo.git -b master

use

window.location.replace("login.php");

or simply window.location("login.php");

It is better than using window.location.href =, because replace() does not put the originating page in the session history, meaning the user won't get stuck in a never-ending back-button fiasco. If you want to simulate someone clicking on a link, use location.href. If you want to simulate an HTTP redirect, use location.replace.

If Cells(1, 1).Formula gives a 1004 error, like in my case, changes it to:

Cells(1, 1).FormulaLocal

While creating url encode them with urlencode

$val=urlencode('http://google.com/?var=234&key=234')

<a href="http://localhost/test.php?id=<?php echo $val ?>">Click here</a>

and while fetching decode it wiht urldecode

This is basic code to find and play an audio file in Swift.

Add your audio file to your Xcode and add the code below.

import AVFoundation

class ViewController: UIViewController {

   var audioPlayer = AVAudioPlayer() // declare globally

   override func viewDidLoad() {
        super.viewDidLoad()

        guard let sound = Bundle.main.path(forResource: "audiofilename", ofType: "mp3") else {
            print("Error getting the mp3 file from the main bundle.")
            return
        }
        do {
            audioPlayer = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: sound))
        } catch {
            print("Audio file error.")
        }
        audioPlayer.play()
    }

    @IBAction func notePressed(_ sender: UIButton) { // Button action
        audioPlayer.stop()
    }
}

Stack Overflow has solved a similar problem with long lines of code by using a DIV and having overflow-x:auto. CSS can't break up words for you.

Its advantages are that it simplifies the usage of WebSockets as you described in #2, and probably more importantly it provides fail-overs to other protocols in the event that WebSockets are not supported on the browser or server. I would avoid using WebSockets directly unless you are very familiar with what environments they don't work and you are capable of working around those limitations.

This is a good read on both WebSockets and Socket.IO.

(And if you have no admin access to the server)

ALTER ROLE <your_login_role> SET search_path TO a,b,c;

Two important things to know about:

1. When a schema name is not simple, it needs to be wrapped in double quotes.
2. The order in which you set default schemas a, b, c matters, as it is also the order in which the schemas will be looked up for tables. So if you have the same table name in more than one schema among the defaults, there will be no ambiguity, the server will always use the table from the first schema you specified for your search_path.

in angular2 2.1.1 I was not able to catch the exception using the (data),(error) pattern, so I implemented it using .catch(...).

It's nice because it can be used with all other Observable chained methods like .retry .map etc.

import {Observable} from 'rxjs/Rx';


  Http
  .put(...)
  .catch(err =>  { 
     notify('UI error handling');
     return Observable.throw(err); // observable needs to be returned or exception raised
  })
  .subscribe(data => ...) // handle success

from documentation:

Returns

(Observable): An observable sequence containing elements from consecutive source sequences until a source sequence terminates successfully.

Try split(",")[i] where i is the index in result array. split gives array below

["test1", " test2", " test3", " test4", " test5"] 

whose element can be accessed by index.

the easy way i found to do this is to put a field with a value and ask the user to remove the text in this field. since bots only fill them up. if the field is not empty it means that the user is not human and it wont be posted. its the same purpose of a captcha code.

It's an older question, but if anyone has a problem with setting this, their documentation is outdated. I made a copy of the php.ini file named php5.ini and now it works.

This worked for me...
I have removed the folders there in .git/worktrees folder and then tried "git delete -D branch-name".

Instead of replace we can force culture like

var x = decimal.Parse("18,285", new NumberFormatInfo() { NumberDecimalSeparator = "," });

it will give output 18.285

I suppose you cannot change the dao.find() method to return an instance of Optional<Obj>, so you have to create the appropriate one yourself.

The following code should help you out. I've create the class OptionalAction, which provides the if-else mechanism for you.

public class OptionalTest
{
  public static Optional<DbObject> getObjectFromDb()
  {
    // doa.find()
    DbObject v = find();

    // create appropriate Optional
    Optional<DbObject> object = Optional.ofNullable(v);

    // @formatter:off
    OptionalAction.
    ifPresent(object)
    .then(o -> o.setAvailable(true))
    .elseDo(o -> System.out.println("Fatal! Object not available!"));
    // @formatter:on
    return object;
  }

  public static void main(String[] args)
  {
    Optional<DbObject> object = getObjectFromDb();
    if (object.isPresent())
      System.out.println(object.get());
    else
      System.out.println("There is no object!");
  }

  // find may return null
  public static DbObject find()
  {
    return (Math.random() > 0.5) ? null : new DbObject();
  }

  static class DbObject
  {
    private boolean available = false;

    public boolean isAvailable()
    {
      return available;
    }

    public void setAvailable(boolean available)
    {
      this.available = available;
    }

    @Override
    public String toString()
    {
      return "DbObject [available=" + available + "]";
    }
  }

  static class OptionalAction
  {
    public static <T> IfAction<T> ifPresent(Optional<T> optional)
    {
      return new IfAction<>(optional);
    }

    private static class IfAction<T>
    {
      private final Optional<T> optional;

      public IfAction(Optional<T> optional)
      {
        this.optional = optional;
      }

      public ElseAction<T> then(Consumer<? super T> consumer)
      {
        if (optional.isPresent())
          consumer.accept(optional.get());
        return new ElseAction<>(optional);
      }
    }

    private static class ElseAction<T>
    {
      private final Optional<T> optional;

      public ElseAction(Optional<T> optional)
      {
        this.optional = optional;
      }

      public void elseDo(Consumer<? super T> consumer)
      {
        if (!optional.isPresent())
          consumer.accept(null);
      }
    }
  }
}

After installing packages from given answers, i still get some errors then i install following package and it works fine:

• php-xml

for specific version:

• php7.0-xml

command for php 7.0

sudo apt-get install php7.0-xml

in some cases you also needs a package php7.0-common . install it same as above command.

There's a static method in ToolStripRenderer class, named CreateDisabledImage. Its usage is as simple as:

Bitmap c = new Bitmap("filename");
Image d = ToolStripRenderer.CreateDisabledImage(c);

It uses a little bit different matrix than the one in the accepted answer and additionally multiplies it by a transparency of value 0.7, so the effect is slightly different than just grayscale, but if you want to just get your image grayed, it's the simplest and best solution.

Not to repeat what everyone already have said but keep the following cheat sheet handly for File manipulations:

1. System.IO.File.ReadAllBytes(filename);
2. File.Exists(filename)
3. Path.Combine(folderName, resOfThePath);
4. Path.GetFullPath(path); // converts a relative path to absolute one
5. Path.GetExtension(path);

You cannot instantiate an abstract class, Jackson neither. You should give Jackson information on how to instantiate MyAbstractClass with a concrete type.

See this answer on stackoverflow: Jackson JSON library: how to instantiate a class that contains abstract fields

And maybe also see Jackson Polymorphic Deserialization

Use boolean function like below:

//a[(contains(@id, 'xx'))=false]

You should use "merge a range of revision".

To merge changes from the trunk to a branch, inside the branch working copy choose "merge range of revisions" and enter the trunk URL and the start and end revisions to merge.

The same in the opposite way to merge a branch in the trunk.

About the --reintegrate flag, check the manual here: http://tortoisesvn.net/docs/release/TortoiseSVN_en/tsvn-dug-merge.html#tsvn-dug-merge-reintegrate

This is strange but Logger.getLogger("global") does not work in my setup (as well as Logger.getLogger(Logger.GLOBAL_LOGGER_NAME)).

However Logger.getLogger("") does the job well.

If you are using the Python wrappers, then (assuming your matrix name is mat):

• mat.shape gives you an array of the type- [height, width, channels]

• mat.size gives you the size of the array

Sample Code:

import cv2
mat = cv2.imread('sample.png')
height, width, channel = mat.shape[:3]
size = mat.size

Internet Explorer doesn't fully support Flexbox due to:

Partial support is due to large amount of bugs present (see known issues).

_{Screenshot and infos taken from caniuse.com}

Notes

Internet Explorer before 10 doesn't support Flexbox, while IE 11 only supports the 2012 syntax.

Known issues

• IE 11 requires a unit to be added to the third argument, the flex-basis property see MSFT documentation.
• In IE10 and IE11, containers with display: flex and flex-direction: column will not properly calculate their flexed childrens' sizes if the container has min-height but no explicit height property. See bug.
• In IE10 the default value for flex is 0 0 auto rather than 0 1 auto as defined in the latest spec.
• IE 11 does not vertically align items correctly when min-height is used. See bug.

Workarounds

Flexbugs is a community-curated list of Flexbox issues and cross-browser workarounds for them. Here's a list of all the bugs with a workaround available and the browsers that affect.

1. Minimum content sizing of flex items not honored
2. Column flex items set to align-items: center overflow their container
3. min-height on a flex container won't apply to its flex items
4. flex shorthand declarations with unitless flex-basis values are ignored
5. Column flex items don't always preserve intrinsic aspect ratios
6. The default flex value has changed
7. flex-basis doesn't account for box-sizing: border-box
8. flex-basis doesn't support calc()
9. Some HTML elements can't be flex containers
10. align-items: baseline doesn't work with nested flex containers
11. Min and max size declarations are ignored when wrapping flex items
12. Inline elements are not treated as flex-items
13. Importance is ignored on flex-basis when using flex shorthand
14. Shrink-to-fit containers with flex-flow: column wrap do not contain their items
15. Column flex items ignore margin: auto on the cross axis
16. flex-basis cannot be animated
17. Flex items are not correctly justified when max-width is used

You need to understand that when you include GROUP BY in your query you are telling SQL to combine rows. you will get one row per unique Locus value. The Having then filters those groups. Usually you specify an aggergate function in the select list like:

--show how many of each Locus there is
SELECT COUNT(*),Locus FROM Genes GROUP BY Locus

--only show the groups that have more than one row in them
SELECT COUNT(*),Locus FROM Genes GROUP BY Locus HAVING COUNT(*)>1

--to just display all the rows for your condition, don't use GROUP BY or HAVING
SELECT * FROM Genes WHERE Locus = '3' AND Chromosome = '10'

Thousands of ways to skin this cat. I realize you're asking about between {{}} speifically, but for others that come here, I think it's worth showing some of the other options.

function on your $scope (IMO, this is your best bet in most scenarios):

  app.controller('MyCtrl', function($scope) {
      $scope.foo = 1;

      $scope.showSomething = function(input) {
           return input == 1 ? 'Foo' : 'Bar';
      };
   });

 <span>{{showSomething(foo)}}</span>

ng-show and ng-hide of course:

 <span ng-show="foo == 1">Foo</span><span ng-hide="foo == 1">Bar</span>

ngSwitch

 <div ng-switch on="foo">
   <span ng-switch-when="1">Foo</span>
   <span ng-switch-when="2">Bar</span>
   <span ng-switch-default>What?</span>
 </div>

A custom filter as Bertrand suggested. (this is your best choice if you have to do the same thing over and over)

app.filter('myFilter', function() {
   return function(input) {
     return input == 1 ? 'Foo' : 'Bar';
   }
}

{{foo | myFilter}}

Or A custom directive:

app.directive('myDirective', function() {
   return {
     restrict: 'E',
     replace: true,
     link: function(scope, elem, attrs) {
       scope.$watch(attrs.value, function(v) {
          elem.text(v == 1 ? 'Foo': 'Bar');
       });
     }
   };
});


<my-directive value="foo"></my-directive>

Personally, in most cases I'd go with a function on my scope, it keeps the markup pretty clean, and it's quick and easy to implement. Unless, that is, you're going to be doing the same exact thing over and over again, in which case I'd go with Bertrand's suggestion and create a filter or possibly a directive, depending on the circumstances.

As always, the most important thing is that your solution is easy to maintain, and is hopefully testable. And that is going to depend completely on your specific situation.

I like Andy's answer, but the id isn't going to necessarily be unique, so here's what I came up with to create a unique ID also. Can be checked at jsfiddle too. Please note that arr.length + 1 may very well not guarantee a unique ID if anything had been removed previously.

var array = [ { id: 1, username: 'fred' }, { id: 2, username: 'bill' }, { id: 3, username: 'ted' } ];
var usedname = 'bill';
var newname = 'sam';

// don't add used name
console.log('before usedname: ' + JSON.stringify(array));
tryAdd(usedname, array);
console.log('before newname: ' + JSON.stringify(array));
tryAdd(newname, array);
console.log('after newname: ' + JSON.stringify(array));

function tryAdd(name, array) {
    var found = false;
    var i = 0;
    var maxId = 1;
    for (i in array) {
        // Check max id
        if (maxId <= array[i].id)
            maxId = array[i].id + 1;

        // Don't need to add if we find it
        if (array[i].username === name)
            found = true;
    }

    if (!found)
        array[++i] = { id: maxId, username: name };
}

First option (bad because of throw-catch, but MS will do work for you):

bool IsValidEmail(string email)
{
    try {
        var mail = new System.Net.Mail.MailAddress(email);
        return true;
    }
    catch {
        return false;
    }
}

Second option is read I Knew How To Validate An Email Address Until I Read The RFC and RFC specification

List<Item> list;
Map<Key,Item> map = new HashMap<Key,Item>();
for (Item i : list) map.put(i.getKey(),i);

Assuming of course that each Item has a getKey() method that returns a key of the proper type.

Use one of these as per your requirements.

Open the linked document in a new window or tab:

 <a href="xyz.html" target="_blank"> Link </a>

Open the linked document in the same frame as it was clicked (this is default):

 <a href="xyz.html" target="_self"> Link </a>

Open the linked document in the parent frame:

 <a href="xyz.html" target="_parent"> Link </a>

Open the linked document in the full body of the window:

 <a href="xyz.html" target="_top"> Link </a>

Open the linked document in a named frame:

 <a href="xyz.html" target="framename"> Link </a>

See MDN

private void Input_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.Key == Key.Return)
        {
            MessageBox.Show("Enter pressed");
        }
    }

This worked for me.

I solved that problem.

I was implementing an OSI Layer (slider window, Level 2) for a network simulation in C++ (Eclipse Juno). I had frames (template <class T>) and its states (state pattern, forward declaration).

The solution is as follows:

In the *.cpp file, you must include the Header file that you forward, i.e.

ifndef STATE_H_
#define STATE_H_
#include <stdlib.h>
#include "Frame.h"

template <class T>
class LinkFrame;

using namespace std;

template <class T>
class State {

  protected:
    LinkFrame<int> *myFrame;

}

Its cpp:

#include "State.h"
#include "Frame.h"
#include  "LinkFrame.h"

template <class T>
bool State<T>::replace(Frame<T> *f){

And... another class.

The default sort for arrays in Javascript is an alphabetical search. If you want a numerical sort, try something like this:

var a = [ 1, 100, 50, 2, 5];
a.sort(function(a,b) { return a - b; });

I will recommended best answer as

<?php echo 'Hello ' . htmlspecialchars($_GET["name"]) . '!'; ?>

Assuming the user entered http://example.com/?name=Hannes

The above example will output:

Hello Hannes!

document.documentElement.outerHTML

This depends on your OS, if you are in a UNIX like environment the ICANON flag is enabled by default, so input is buffered until the next '\n' or EOF. By disabling the canonical mode you will get the characters immediately. This is also possible on other platforms, but there is no straight forward cross-platform solution.

EDIT: I see you specified that you use Ubuntu. I just posted something similar yesterday, but be aware that this will disable many default behaviors of your terminal.

#include<stdio.h>
#include <termios.h>            //termios, TCSANOW, ECHO, ICANON
#include <unistd.h>     //STDIN_FILENO


int main(void){   
    int c;   
    static struct termios oldt, newt;

    /*tcgetattr gets the parameters of the current terminal
    STDIN_FILENO will tell tcgetattr that it should write the settings
    of stdin to oldt*/
    tcgetattr( STDIN_FILENO, &oldt);
    /*now the settings will be copied*/
    newt = oldt;

    /*ICANON normally takes care that one line at a time will be processed
    that means it will return if it sees a "\n" or an EOF or an EOL*/
    newt.c_lflag &= ~(ICANON);          

    /*Those new settings will be set to STDIN
    TCSANOW tells tcsetattr to change attributes immediately. */
    tcsetattr( STDIN_FILENO, TCSANOW, &newt);

    /*This is your part:
    I choose 'e' to end input. Notice that EOF is also turned off
    in the non-canonical mode*/
    while((c=getchar())!= 'e')      
        putchar(c);                 

    /*restore the old settings*/
    tcsetattr( STDIN_FILENO, TCSANOW, &oldt);


    return 0;
}

You will notice, that every character appears twice. This is because the input is immediately echoed back to the terminal and then your program puts it back with putchar() too. If you want to disassociate the input from the output, you also have to turn of the ECHO flag. You can do this by simply changing the appropriate line to:

newt.c_lflag &= ~(ICANON | ECHO); 

How about with a :before pseudoelement:

a:before {
  content: '\a';
  white-space: pre;
}

ENV['RAILS_ENV'] is now deprecated.

You should use Rails.env which is clearly much nicer.

    // Once finished with the bitmap objects, we deallocate them.
    originalBMP.Dispose();

    bannerBMP.Dispose();
    oGraphics.Dispose();

This is a programming style that you'll regret sooner or later. Sooner is knocking on the door, you forgot one. You are not disposing newBitmap. Which keeps a lock on the file until the garbage collector runs. If it doesn't run then the second time you try to save to the same file you'll get the klaboom. GDI+ exceptions are too miserable to give a good diagnostic so serious head-scratching ensues. Beyond the thousands of googlable posts that mention this mistake.

Always favor using the using statement. Which never forgets to dispose an object, even if the code throws an exception.

using (var newBitmap = new Bitmap(thumbBMP)) {
    newBitmap.Save("~/image/thumbs/" + "t" + objPropBannerImage.ImageId, ImageFormat.Jpeg);
}

Albeit that it is very unclear why you even create a new bitmap, saving thumbBMP should already be good enough. Anyhoo, give the rest of your disposable objects the same using love.

regular expression normally uses * and + in theory of language. I encounter the same bug while executing the line code

re.split("*",text)

to solve it, it needs to include \ before * and +

re.split("\*",text)

To get body content from javascript ,i have tried the following code:

var frameObj = document.getElementById('id_description_iframe');

var frameContent = frameObj.contentWindow.document.body.innerHTML;

where "id_description_iframe" is your iframe's id. This code is working fine for me.

Swift 4

I've had some minor issues when updating the ViewControllers view using UIDevice.current.orientation, such as updating constraints of tableview cells during rotation or animation of subviews.

Instead of the above methods I am currently comparing the transition size to the view controllers view size. This seems like the proper way to go since one has access to both at this point in code:

override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
    super.viewWillTransition(to: size, with: coordinator)
    print("Will Transition to size \(size) from super view size \(self.view.frame.size)")

    if (size.width > self.view.frame.size.width) {
        print("Landscape")
    } else {
        print("Portrait")
    }

    if (size.width != self.view.frame.size.width) {
        // Reload TableView to update cell's constraints.
    // Ensuring no dequeued cells have old constraints.
        DispatchQueue.main.async {
            self.tableView.reloadData()
        }
    }


}

Output on a iPhone 6:

Will Transition to size (667.0, 375.0) from super view size (375.0, 667.0) 
Will Transition to size (375.0, 667.0) from super view size (667.0, 375.0)

The following produces more general k-fold cross-validation splits. Your 50-50 partitioning would be achieved by making k=2 below, all you would have to to is to pick one of the two partitions produced. Note: I haven't tested the code, but I'm pretty sure it should work.

import random, math

def k_fold(myfile, myseed=11109, k=3):
    # Load data
    data = open(myfile).readlines()

    # Shuffle input
    random.seed=myseed
    random.shuffle(data)

    # Compute partition size given input k
    len_part=int(math.ceil(len(data)/float(k)))

    # Create one partition per fold
    train={}
    test={}
    for ii in range(k):
        test[ii]  = data[ii*len_part:ii*len_part+len_part]
        train[ii] = [jj for jj in data if jj not in test[ii]]

    return train, test      

You need to add your ORACLE_HOME definition in your listener.ora file. Right now its not registered with any ORACLE_HOME.

objdump is another good one on linux.

Here is another ES6 way of doing it with O(n) complexity

const result = Object.entries(
    ['pear', 'apple', 'orange', 'apple'].reduce((previous, current) => {
        if (previous[current] === undefined) previous[current] = 1;
        else previous[current]++;
        return previous;
    }, {})).reduce((previous, current) => (current[1] >= previous[1] ? current : previous))[0];
console.log("Max value : " + result);

ArrayList is randomly accessible, while LinkedList is really cheap to expand and remove elements from. For most cases, ArrayList is fine.

Unless you've created large lists and measured a bottleneck, you'll probably never need to worry about the difference.

I stumbled across this question while hitting this road block myself. I ended up writing a piece of code real quick to handle this ReDim Preserve on a new sized array (first or last dimension). Maybe it will help others who face the same issue.

So for the usage, lets say you have your array originally set as MyArray(3,5), and you want to make the dimensions (first too!) larger, lets just say to MyArray(10,20). You would be used to doing something like this right?

 ReDim Preserve MyArray(10,20) '<-- Returns Error

But unfortunately that returns an error because you tried to change the size of the first dimension. So with my function, you would just do something like this instead:

 MyArray = ReDimPreserve(MyArray,10,20)

Now the array is larger, and the data is preserved. Your ReDim Preserve for a Multi-Dimension array is complete. :)

And last but not least, the miraculous function: ReDimPreserve()

'redim preserve both dimensions for a multidimension array *ONLY

I wrote this in like 20 minutes, so there's no guarantees. But if you would like to use or extend it, feel free. I would've thought that someone would've had some code like this up here already, well apparently not. So here ya go fellow gearheads.

For me Visual Studio had created a projectname.v11 of type "Visual Studio Solution User Options". I deleted this file and restarted and everything was fine.

Save your files as ~/.config/fish/functions/{some_function_name}.fish and they should get autoloaded when you start fish.

HTTP code 302 is for redirection see http://en.wikipedia.org/wiki/HTTP_302.

It tells the browse reading a page to go somewhere else and load another page. Its usage is very common.

Use load instead of ready:

$(document).load(function () {
 // code here
});

Update You need to use .on() since jQuery 1.8. (http://api.jquery.com/on/)

$(window).on('load', function() {
 // code here
});

From this answer:

According to http://blog.jquery.com/2016/06/09/jquery-3-0-final-released/:

Removed deprecated event aliases

.load, .unload, and .error, deprecated since jQuery 1.8, are no more. Use .on() to register listeners.

In CentOS (but the same may apply to other distros too) if you install the php7x-gd module followed by Apache restart and still the php -i does not show the GD Support => enabled it might mean that the php.ini was not automatically configured to support this extension.

All you have to to is either to edit the /etc/php/php.ini or to create a /etc/php.d/gd.ini file with the following content:

[gd]
extension=/path/to/gd.so # use the gd.so absolute path here

Integer.valueOf() returns an Integer object, while Integer.parseInt() returns an int primitive.

This code works too. Put this on the root controller of the navigation controller:

self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"" style:UIBarButtonItemStylePlain target:nil action:nil];

This worked for me:

// Check if URL contains the word "car" or "CAR"
   if (stripos($_SERVER['REQUEST_URI'], 'car' )!==false){
   echo "Car here";
   } else {
   echo "No car here";
   }

If you want to use HTML in the echo, be sure to use ' ' instead of " ".
I use this code to show an alert on my webpage https://geaskb.nl/ 
where the URL contains the word "Omnik" 
but hide the alert on pages that do not contain the word "Omnik" in the URL.

Get the difference of two lists using Any(). The Linq Any() function returns a boolean if a condition is met but you can use it to return the difference of two lists:

var difference = ListA.Where(a => !ListB.Any(b => b.ListItem == a.ListItem)).ToList();

FileStreamResult certainly works. But if you look at the Microsoft Docs, it inherits from ActionResult -> FileResult, which has another derived class FileContentResult. It "sends the contents of a binary file to the response". So if you already have the byte[], you should just use FileContentResult instead.

public ActionResult DisplayPDF()
{
    byte[] byteArray = GetPdfFromWhatever();

    return new FileContentResult(byteArray, "application/pdf");
}

It looks you are almost there. Try:

if(error == true){

    // Your application has indicated there's an error
    window.setTimeout(function(){

        // Move to a new location or you can do something else
        window.location.href = "https://www.google.co.in";

    }, 5000);

}

Just wanted to share with you:
I happened to get this error after changing Digital Ocean machine (IP address). Apparently Gmail recognized it as a hacking attack. After following their directions, and approving the new IP address the code is back and running.

You probably mean heap memory, not memory heap.

Heap memory is essentially a large pool of memory (typically per process) from which the running program can request chunks. This is typically called dynamic allocation.

It is different from the Stack, where "automatic variables" are allocated. So, for example, when you define in a C function a pointer variable, enough space to hold a memory address is allocated on the stack. However, you will often need to dynamically allocate space (With malloc) on the heap and then provide the address where this memory chunk starts to the pointer.

'int' object is not subscriptable is TypeError in Python. To better understand how this error occurs, let us consider the following example:

list1 = [1, 2, 3]
print(list1[0][0])

If we run the code, you will receive the same TypeError in Python3.

TypeError: 'int' object is not subscriptable

Here the index of the list is out of range. If the code was modified to:

print(list1[0])

The output will be 1(as indexing in Python Lists starts at zero), as now the index of the list is in range.

1

When the code(given alongside the question) is run, the TypeError occurs and it points to line 4 of the code :

int([x[age1]])

The intention may have been to create a list of an integer number(although creating a list for a single number was not at all required). What was required was that to just assign the input(which in turn converted to integer) to a variable.

Hence, it's better to code this way:

name = input("What's your name? ")
age = int(input('How old are you? '))
twenty_one = 21 - age
if(twenty_one < 0):
    print('Hi {0}, you are above 21 years' .format(name))
elif(twenty_one == 0):
    print('Hi {0}, you are 21 years old' .format(name))
else:
    print('Hi {0}, you will be 21 years in {1} year(s)' .format(name, twenty_one))

The output:

What's your name? Steve
How old are you? 21
Hi Steve, you are 21 years old

I'm adding this answer because I didn’t see it here in full. I was able to do this using elementFromPoint. So basically:

• attach a click to the div you want to be clicked through
• hide it
• determine what element the pointer is on
• fire the click on the element there.

var range-selector= $("")
    .css("position", "absolute").addClass("range-selector")
    .appendTo("")
    .click(function(e) {
        _range-selector.hide();

        $(document.elementFromPoint(e.clientX,e.clientY)).trigger("click");
    });

In my case the overlaying div is absolutely positioned—I am not sure if this makes a difference. This works on IE8/9, Safari Chrome and Firefox at least.

That happened for me, because I was invoking commit() from subfragment which was leaking activity. It kept activity as a property and on a rotation activity variable was not updated by onAttach(); So I was trying to commit transaction on zombie Activity by retained (setRetainInstance(true);) fragment.

if you use ubuntu 16.04 (maybe and above),you have this module already but not enabled by default. Just do this:

sudo phpenmod mysqli

Linux users (tested on ubuntu 14.04)

by default (on linux and mac) pycharm uses the OS's password manager. To access the passwords on ubuntu open the program "Passwords and Keys".

Once open filter on "idea" and edit the relevant passwords.

No need to restart pycharm for me.
Using pycharm 17.2

$('#id').attr('onclick', 'function()');

Right now (11 Jul 2015) this solution is still working (jquery 2.1.4); in my opinion, it is the best one to pick up.

A solution for finding a anchor tag if having a particular keyword would be the following:

from bs4 import BeautifulSoup
from urllib.request import urlopen,Request
from urllib.parse import urljoin,urlparse

rawLinks=soup.findAll('a',href=True)
for link in rawLinks:
    innercontent=link.text
    if keyword.lower() in innercontent.lower():
        print(link)
