I spent lots of hours on it when I call PHP script to init
and commit
to git.
And I found the work flow should be as:
git init
git config user.name "someone"
git config user.email "[email protected]"
git add *
git commit -m "some init msg"
If you swap [23] and 1, the config will not work at all.
I wish this will do some help.
I had the same problem after changing JDK from 1.6 to 1.7 in my pom.xml and setting Maven 3 path + JDK project settings to 1.7.
What did it for me was => File -> Invalidate Caches and Restart
PS: problem occured again, so i just reimported the full project after deleting the .idea folder and now it works fine as usual :)
Run like:
$ mvn help:describe -DartifactId=maven-war-plugin -DgroupId=org.apache.maven.plugins
for plug-in that have no version. You get output:
Name: Maven WAR Plugin Description: Builds a Web Application Archive (WAR) file from the project output and its dependencies. Group Id: org.apache.maven.plugins Artifact Id: maven-war-plugin Version: 2.2 Goal Prefix: war
Use version that shown in output.
UPDATE If you want to select among list of versions, use http://search.maven.org/ or http://mvnrepository.com/ Note that your favorite Java IDE must have Maven package search dialog. Just check docs.
SUPER UPDATE I also use:
$ mvn dependency:tree
$ mvn dependency:list
$ mvn dependency:resolve
$ mvn dependency:resolve-plugins # <-- THIS
Recently I discover how to get latest version for plug-in (or library) so no longer needs for googling or visiting Maven Central:
$ mvn versions:display-dependency-updates
$ mvn versions:display-plugin-updates # <-- THIS
There are two things you need to check:
To ensure that your user account has administrator privilege, run lusrmgr.msc
from the Windows Start > Run menu to bring up the Local Users and Groups
Windows. Double-click on your user account that appears under Users
, and verifies that it is a member of Administrators
.
To disable UAC (as an administrator), from Control Panel
:
Change User Account Control
settings in the search results.Never notify
and click OK.open up the User Accounts
window from Control Panel
. Click on the Turn User Account Control on or off
option, and un-check the checkbox.
Alternately, if you don't want to disable UAC, you will have to install XAMPP in a different folder, outside of C:\Program Files (x86)
, such as C:\xampp
.
Hope this helps.

As I understand it, you should only use up to 49151, as from 49152 up to 65535 are reserved for Ephemeral ports
First, you can switch on an enum
in Java. I'm guessing you intended to say you can’t, but you can. char
s have a set range of values, so it's easy to compare. Strings can be anything.
A switch
statement is usually implemented as a jump table (branch table) in the underlying compilation, which is only possible with a finite set of values. C# can switch on strings, but it causes a performance decrease because a jump table cannot be used.
Java 7 and later supports String
switches with the same characteristics.
maybe you're trying to
for i in range(inp)
This will print your input value (inp) times, to print it only once, follow: for i in range(inp - inp + 1 ) print(i)
I just had this error because I wasn't using range()
I guess this is because your nodejs cert has expired. Type this line : npm set registry http://registry.npmjs.org/
and after that try again with npm install . This actually solved my problem.

Using gcc 3.4 and 4.1 on very large trees (sometimes making use of distcc), I have yet to see any speed up when using #pragma once in lieu of, or in combination with standard include guards.
I really don't see how its worth potentially confusing older versions of gcc, or even other compilers since there's no real savings. I have not tried all of the various de-linters, but I'm willing to bet it will confuse many of them.
I too wish it had been adopted early on, but I can see the argument "Why do we need that when ifndef works perfectly fine?". Given C's many dark corners and complexities, include guards are one of the easiest, self explaining things. If you have even a small knowledge of how the preprocessor works, they should be self explanatory.
If you do observe a significant speed up, however, please update your question.
target is the element that triggered the event (e.g., the user clicked on)
currenttarget is the element that the event listener is attached to.
$(element).on("click mousedown mouseup focus blur keydown change",function(e){
console.log(e);
});
That will get you a lot (but not all) of the information on if an event is fired... other than manually coding it like this, I can't think of any other way to do that.
i am using NetBeans IDE 7.2.1 as my developer environmental and there you have an option to configure the JForm properties.
in the JForm Properties go to the 'Code' tab and configure the 'Generate Center'. you will need first to set the Form Size Policy to 'Generate Resize Code'.
Guys if it helps I will share with you my solution: Definition of Custom attribute:
[AttributeUsage(AttributeTargets.Field,AllowMultiple = false)]
public class EnumDisplayName : Attribute
{
public string Name { get; private set; }
public EnumDisplayName(string name)
{
Name = name;
}
}
Now because I needed it inside of HtmlHelper definition of HtmlHelper Extension:
public static class EnumHelper
{
public static string EnumDisplayName(this HtmlHelper helper,EPriceType priceType)
{
//Get every fields from enum
var fields = priceType.GetType().GetFields();
//Foreach field skipping 1`st fieldw which keeps currently sellected value
for (int i = 0; i < fields.Length;i++ )
{
//find field with same int value
if ((int)fields[i].GetValue(priceType) == (int)priceType)
{
//get attributes of found field
var attributes = fields[i].GetCustomAttributes(false);
if (attributes.Length > 0)
{
//return name of found attribute
var retAttr = (EnumDisplayName)attributes[0];
return retAttr.Name;
}
}
}
//throw Error if not found
throw new Exception("Blad podczas ustalania atrybutów dla typu ceny allegro");
}
}
Hope it helps
Yes, this is possible:
List<BigDecimal> bdList = new ArrayList<>();
//populate list
BigDecimal result = bdList.stream()
.reduce(BigDecimal.ZERO, BigDecimal::add);
What it does is:
List<BigDecimal>
.Stream<BigDecimal>
Call the reduce method.
3.1. We supply an identity value for addition, namely BigDecimal.ZERO
.
3.2. We specify the BinaryOperator<BigDecimal>
, which adds two BigDecimal
's, via a method reference BigDecimal::add
.
I see that you have added new data, therefore the new answer will become:
List<Invoice> invoiceList = new ArrayList<>();
//populate
Function<Invoice, BigDecimal> totalMapper = invoice -> invoice.getUnit_price().multiply(invoice.getQuantity());
BigDecimal result = invoiceList.stream()
.map(totalMapper)
.reduce(BigDecimal.ZERO, BigDecimal::add);
It is mostly the same, except that I have added a totalMapper
variable, that has a function from Invoice
to BigDecimal
and returns the total price of that invoice.
Then I obtain a Stream<Invoice>
, map it to a Stream<BigDecimal>
and then reduce it to a BigDecimal
.
Now, from an OOP design point I would advice you to also actually use the total()
method, which you have already defined, then it even becomes easier:
List<Invoice> invoiceList = new ArrayList<>();
//populate
BigDecimal result = invoiceList.stream()
.map(Invoice::total)
.reduce(BigDecimal.ZERO, BigDecimal::add);
Here we directly use the method reference in the map
method.
Try specifying a DC in DomainB using the -Server
property. Ex:

If you have Ruby, you can install the mysql2xxxx gem (not the mysql2json gem, which is a different gem):
$ gem install mysql2xxxx
and then run the command
$ mysql2json --user=root --password=password --database=database_name --execute "select * from mytable" >mytable.json
The gem also provides mysql2csv
and mysql2xml
. It's not as fast as mysqldump, but also doesn't suffer from some of mysqldump's weirdnesses (like only being able to dump CSV from the same computer as the MySQL server itself)
I have fixed the similar issue by passing associative array as the first argument inside Builder::with
method.
Imagine you want to include child relations by some dynamic parameters but don't want to filter parent results.
Model.php
public function child ()
{
return $this->hasMany(ChildModel::class);
}
Then, in other place, when your logic is placed you can do something like filtering relation by HasMany
class. For example (very similar to my case):
$search = 'Some search string';
$result = Model::query()->with(
[
'child' => function (HasMany $query) use ($search) {
$query->where('name', 'like', "%{$search}%");
}
]
);
Then you will filter all the child results but parent models will not filter. Thank you for attention.
Guava now has Base64 decoding built in.
Use BaseEncoding.base64().decode()
As for dealing with possible whitespace in input use
BaseEncoding.base64().decode(CharMatcher.WHITESPACE.removeFrom(...));

raw_data['Mycol'] = pd.to_datetime(raw_data['Mycol'], format='%d%b%Y:%H:%M:%S.%f')
works, however it results in a Python warning of
A value is trying to be set on a copy of a slice from a DataFrame.
Try using .loc[row_indexer,col_indexer] = value
instead
I would guess this is due to some chaining indexing.
It basically tells the program when you encounter an error just continue at the next line.

maybe you need to grant more permissions to your files.
suppose your code are under /var/www/my_project
try chmod -R 777 /var/www/my_project
For the simple case of:
The simplest solution is:
df[['A', 'B']] = df['AB'].str.split(' ', 1, expand=True)
You must use expand=True
if your strings have a non-uniform number of splits and you want None
to replace the missing values.
Notice how, in either case, the .tolist()
method is not necessary. Neither is zip()
.
Andy Hayden's solution is most excellent in demonstrating the power of the str.extract()
method.
But for a simple split over a known separator (like, splitting by dashes, or splitting by whitespace), the .str.split()
method is enough1. It operates on a column (Series) of strings, and returns a column (Series) of lists:
>>> import pandas as pd
>>> df = pd.DataFrame({'AB': ['A1-B1', 'A2-B2']})
>>> df
AB
0 A1-B1
1 A2-B2
>>> df['AB_split'] = df['AB'].str.split('-')
>>> df
AB AB_split
0 A1-B1 [A1, B1]
1 A2-B2 [A2, B2]
1: If you're unsure what the first two parameters of .str.split()
do,
I recommend the docs for the plain Python version of the method.
But how do you go from:
to:
Well, we need to take a closer look at the .str
attribute of a column.
It's a magical object that is used to collect methods that treat each element in a column as a string, and then apply the respective method in each element as efficient as possible:
>>> upper_lower_df = pd.DataFrame({"U": ["A", "B", "C"]})
>>> upper_lower_df
U
0 A
1 B
2 C
>>> upper_lower_df["L"] = upper_lower_df["U"].str.lower()
>>> upper_lower_df
U L
0 A a
1 B b
2 C c
But it also has an "indexing" interface for getting each element of a string by its index:
>>> df['AB'].str[0]
0 A
1 A
Name: AB, dtype: object
>>> df['AB'].str[1]
0 1
1 2
Name: AB, dtype: object
Of course, this indexing interface of .str
doesn't really care if each element it's indexing is actually a string, as long as it can be indexed, so:
>>> df['AB'].str.split('-', 1).str[0]
0 A1
1 A2
Name: AB, dtype: object
>>> df['AB'].str.split('-', 1).str[1]
0 B1
1 B2
Name: AB, dtype: object
Then, it's a simple matter of taking advantage of the Python tuple unpacking of iterables to do
>>> df['A'], df['B'] = df['AB'].str.split('-', 1).str
>>> df
AB AB_split A B
0 A1-B1 [A1, B1] A1 B1
1 A2-B2 [A2, B2] A2 B2
Of course, getting a DataFrame out of splitting a column of strings is so useful that the .str.split()
method can do it for you with the expand=True
parameter:
>>> df['AB'].str.split('-', 1, expand=True)
0 1
0 A1 B1
1 A2 B2
So, another way of accomplishing what we wanted is to do:
>>> df = df[['AB']]
>>> df
AB
0 A1-B1
1 A2-B2
>>> df.join(df['AB'].str.split('-', 1, expand=True).rename(columns={0:'A', 1:'B'}))
AB A B
0 A1-B1 A1 B1
1 A2-B2 A2 B2
The expand=True
version, although longer, has a distinct advantage over the tuple unpacking method. Tuple unpacking doesn't deal well with splits of different lengths:
>>> df = pd.DataFrame({'AB': ['A1-B1', 'A2-B2', 'A3-B3-C3']})
>>> df
AB
0 A1-B1
1 A2-B2
2 A3-B3-C3
>>> df['A'], df['B'], df['C'] = df['AB'].str.split('-')
Traceback (most recent call last):
[...]
ValueError: Length of values does not match length of index
>>>
But expand=True
handles it nicely by placing None
in the columns for which there aren't enough "splits":
>>> df.join(
... df['AB'].str.split('-', expand=True).rename(
... columns={0:'A', 1:'B', 2:'C'}
... )
... )
AB A B C
0 A1-B1 A1 B1 None
1 A2-B2 A2 B2 None
2 A3-B3-C3 A3 B3 C3

This is what worked for me. Issue is earlier I didn't set Content Type(header) when I used exchange method.
MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
map.add("param1", "123");
map.add("param2", "456");
map.add("param3", "789");
map.add("param4", "123");
map.add("param5", "456");
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
final HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<MultiValueMap<String, String>>(map ,
headers);
JSONObject jsonObject = null;
try {
RestTemplate restTemplate = new RestTemplate();
ResponseEntity<String> responseEntity = restTemplate.exchange(
"https://url", HttpMethod.POST, entity,
String.class);
if (responseEntity.getStatusCode() == HttpStatus.CREATED) {
try {
jsonObject = new JSONObject(responseEntity.getBody());
} catch (JSONException e) {
throw new RuntimeException("JSONException occurred");
}
}
} catch (final HttpClientErrorException httpClientErrorException) {
throw new ExternalCallBadRequestException();
} catch (HttpServerErrorException httpServerErrorException) {
throw new ExternalCallServerErrorException(httpServerErrorException);
} catch (Exception exception) {
throw new ExternalCallServerErrorException(exception);
}
ExternalCallBadRequestException and ExternalCallServerErrorException are the custom exceptions here.
Note: Remember HttpClientErrorException is thrown when a 4xx error is received. So if the request you send is wrong either setting header or sending wrong data, you could receive this exception.
Passsing bitmap as parceable in bundle between activity is not a good idea because of size limitation of Parceable(1mb). You can store the bitmap in a file in internal storage and retrieve the stored bitmap in several activities. Here's some sample code.
To store bitmap in a file myImage in internal storage:
public String createImageFromBitmap(Bitmap bitmap) {
String fileName = "myImage";//no .png or .jpg needed
try {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
FileOutputStream fo = openFileOutput(fileName, Context.MODE_PRIVATE);
fo.write(bytes.toByteArray());
// remember close file output
fo.close();
} catch (Exception e) {
e.printStackTrace();
fileName = null;
}
return fileName;
}
Then in the next activity you can decode this file myImage to a bitmap using following code:
//here context can be anything like getActivity() for fragment, this or MainActivity.this
Bitmap bitmap = BitmapFactory.decodeStream(context.openFileInput("myImage"));
Note A lot of checking for null and scaling bitmap's is ommited.
Assuming you use Java 5 enums (which is not so certain since you mention old Enumeration
class), you can use the valueOf
method of java.lang.Enum
subclass:
MyEnum e = MyEnum.valueOf("ONE_OF_CONSTANTS");
In [7]: %%timeit dic = {str(i):i for i in xrange(10)}; dic['10'] = None; dic['5'] = None
...: dic = {k: v for k, v in dic.items() if v is not None}
1000000 loops, best of 7: 375 ns per loop
In [8]: %%timeit dic = {str(i):i for i in xrange(10)}; dic['10'] = None; dic['5'] = None
...: dic = dict((k, v) for k, v in dic.items() if v is not None)
1000000 loops, best of 7: 681 ns per loop
In [10]: %%timeit dic = {str(i):i for i in xrange(10)}; dic['10'] = None; dic['5'] = None
...: for k, v in dic.items():
...: if v is None:
...: del dic[k]
...:
10000000 loops, best of 7: 160 ns per loop
so loop and delete is the fastest at 160ns, list comprehension is half as slow at ~375ns and with a call to dict()
is half as slow again ~680ns.
Wrapping 3 into a function brings it back down again to about 275ns. Also for me PyPy was about twice as fast as neet python.
For anything with requests to URLs you might want to check out requests. For JSON in particular:

I've created a JUnit Test class(as a additional knowledge/info) for the same issue. Hope you'll be finding this helpful.
public class StringHelper {
//Separate words from String which has gigits
public String drawDigitsFromString(String strValue){
String str = strValue.trim();
String digits="";
for (int i = 0; i < str.length(); i++) {
char chrs = str.charAt(i);
if (Character.isDigit(chrs))
digits = digits+chrs;
}
return digits;
}
}
And JUnit Test case is:
public class StringHelperTest {
StringHelper helper;
@Before
public void before(){
helper = new StringHelper();
}
@Test
public void testDrawDigitsFromString(){
assertEquals("187111", helper.drawDigitsFromString("TCS187TCS111"));
}
}
If you would like to have a histogram of unique values here's oneliner
import numpy as np
unique_labels, unique_counts = np.unique(labels_list, return_counts=True)
labels_histogram = dict(zip(unique_labels, unique_counts))
If both the list are too big and when we use lamda expression then it will take a long time to fetch . Better to use linq in this case to fetch parameters list:
var items = (from x in parameters
join y in myStrings on x.Source equals y
select x)
.ToList();
If you want an alternative to ReflectionTestUtils from Spring in mockito, use
Whitebox.setInternalState(first, "second", sec);
document.getElementById("fname").style.borderTopColor = 'red';
document.getElementById("fname").style.borderBottomColor = 'red';
If you are still thinking what the! You would not be alone, its actually not that complicated really, let me explain.
We want to turn the following list into a dictionary using the odd entries (counting from 1) as keys mapped to their consecutive even entries.
l = ["a", "b", "c", "d", "e"]
To create a dictionary we can use the built in dict
function for Mapping Types as per the manual the following methods are supported.
dict(one=1, two=2)
dict({'one': 1, 'two': 2})
dict(zip(('one', 'two'), (1, 2)))
dict([['two', 2], ['one', 1]])
The last option suggests that we supply a list of lists with 2 values or (key, value)
tuples, so we want to turn our sequential list into:
l = [["a", "b"], ["c", "d"], ["e",]]
We are also introduced to the zip
function, one of the built-in functions which the manual explains:
returns a list of tuples, where the i-th tuple contains the i-th element from each of the arguments
In other words if we can turn our list into two lists a, c, e
and b, d
then zip
will do the rest.
Slicings which we see used with Strings and also further on in the List section which mainly uses the range or short slice notation but this is what the long slice notation looks like and what we can accomplish with step:
>>> l[::2]
['a', 'c', 'e']
>>> l[1::2]
['b', 'd']
>>> zip(['a', 'c', 'e'], ['b', 'd'])
[('a', 'b'), ('c', 'd')]
>>> dict(zip(l[::2], l[1::2]))
{'a': 'b', 'c': 'd'}
Even though this is the simplest way to understand the mechanics involved there is a downside because slices are new list objects each time, as can be seen with this cloning example:
>>> a = [1, 2, 3]
>>> b = a
>>> b
[1, 2, 3]
>>> b is a
True
>>> b = a[:]
>>> b
[1, 2, 3]
>>> b is a
False
Even though b looks like a they are two separate objects now and this is why we prefer to use the grouper recipe instead.
Although the grouper is explained as part of the itertools module it works perfectly fine with the basic functions too.
Some serious voodoo right? =) But actually nothing more than a bit of syntax sugar for spice, the grouper recipe is accomplished by the following expression.
*[iter(l)]*2
Which more or less translates to two arguments of the same iterator wrapped in a list, if that makes any sense. Lets break it down to help shed some light.
>>> l*2
['a', 'b', 'c', 'd', 'e', 'a', 'b', 'c', 'd', 'e']
>>> [l]*2
[['a', 'b', 'c', 'd', 'e'], ['a', 'b', 'c', 'd', 'e']]
>>> [iter(l)]*2
[<listiterator object at 0x100486450>, <listiterator object at 0x100486450>]
>>> zip([iter(l)]*2)
[(<listiterator object at 0x1004865d0>,),(<listiterator object at 0x1004865d0>,)]
>>> zip(*[iter(l)]*2)
[('a', 'b'), ('c', 'd')]
>>> dict(zip(*[iter(l)]*2))
{'a': 'b', 'c': 'd'}
As you can see the addresses for the two iterators remain the same so we are working with the same iterator which zip then first gets a key from and then a value and a key and a value every time stepping the same iterator to accomplish what we did with the slices much more productively.
You would accomplish very much the same with the following which carries a smaller What the? factor perhaps.
>>> it = iter(l)
>>> dict(zip(it, it))
{'a': 'b', 'c': 'd'}
What about the empty key e
if you've noticed it has been missing from all the examples which is because zip
picks the shortest of the two arguments, so what are we to do.
Well one solution might be adding an empty value to odd length lists, you may choose to use append
and an if
statement which would do the trick, albeit slightly boring, right?
>>> if len(l) % 2:
... l.append("")
>>> l
['a', 'b', 'c', 'd', 'e', '']
>>> dict(zip(*[iter(l)]*2))
{'a': 'b', 'c': 'd', 'e': ''}
Now before you shrug away to go type from itertools import izip_longest
you may be surprised to know it is not required, we can accomplish the same, even better IMHO, with the built in functions alone.
I prefer to use the map() function instead of izip_longest() which not only uses shorter syntax doesn't require an import but it can assign an actual None
empty value when required, automagically.
>>> l = ["a", "b", "c", "d", "e"]
>>> l
['a', 'b', 'c', 'd', 'e']
>>> dict(map(None, *[iter(l)]*2))
{'a': 'b', 'c': 'd', 'e': None}
Comparing performance of the two methods, as pointed out by KursedMetal, it is clear that the itertools module far outperforms the map function on large volumes, as a benchmark against 10 million records show.
$ time python -c 'dict(map(None, *[iter(range(10000000))]*2))'
real 0m3.755s
user 0m2.815s
sys 0m0.869s
$ time python -c 'from itertools import izip_longest; dict(izip_longest(*[iter(range(10000000))]*2, fillvalue=None))'
real 0m2.102s
user 0m1.451s
sys 0m0.539s
However the cost of importing the module has its toll on smaller datasets with map returning much quicker up to around 100 thousand records when they start arriving head to head.
$ time python -c 'dict(map(None, *[iter(range(100))]*2))'
real 0m0.046s
user 0m0.029s
sys 0m0.015s
$ time python -c 'from itertools import izip_longest; dict(izip_longest(*[iter(range(100))]*2, fillvalue=None))'
real 0m0.067s
user 0m0.042s
sys 0m0.021s
$ time python -c 'dict(map(None, *[iter(range(100000))]*2))'
real 0m0.074s
user 0m0.050s
sys 0m0.022s
$ time python -c 'from itertools import izip_longest; dict(izip_longest(*[iter(range(100000))]*2, fillvalue=None))'
real 0m0.075s
user 0m0.047s
sys 0m0.024s
See nothing to it! =)

As of 2018, there is also iText7 (A next iteration of old iTextSharp library) and its HTML to PDF package available: itext7.pdfhtml
Usage is straightforward:
HtmlConverter.ConvertToPdf(
new FileInfo(@"Path\to\Html\File.html"),
new FileInfo(@"Path\to\Pdf\File.pdf")
);
Method has many more overloads.
Update: iText* family of products has dual licensing model: free for open source, paid for commercial use.
tl;dr; Excel does all of this natively - use filters and or tables
(http://office.microsoft.com/en-gb/excel-help/filter-data-in-an-excel-table-HA102840028.aspx)
You can open excel programatically through an oledb connection and execute SQL on the tables within the worksheet.
But you can do everything you are asking to do with no formulas just filters.
have a play around.. some things to note:
DO it with filters unless you are going to do it a lot or you want to automate importing data somewhere or something.. but for completeness:
A c# option:
OleDbConnection ExcelFile = new OleDbConnection( String.Format( "Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=\"Excel 12.0;HDR=YES\"", filename));
ExcelFile.Open();
a handy place to start is to take a look at the schema as there may be more there than you think:
List<String> excelSheets = new List<string>();
// Add the sheet name to the string array.
foreach (DataRow row in dt.Rows) {
string temp = row["TABLE_NAME"].ToString();
if (temp[temp.Length - 1] == '$') {
excelSheets.Add(row["TABLE_NAME"].ToString());
}
}
then when you want to query a sheet:
OleDbDataAdapter da = new OleDbDataAdapter("select * from [" + sheet + "]", ExcelFile);
dt = new DataTable();
da.Fill(dt);
NOTE - Use Tables in excel!:
Excel has "tables" functionality that make data behave more like a table.. this gives you some great benefits but is not going to let you do every type of query.
http://office.microsoft.com/en-gb/excel-help/overview-of-excel-tables-HA010048546.aspx
For tabular data in excel this is my default.. first thing i do is click into the data then select "format as table" from the home section on the ribbon. this gives you filtering, and sorting by default and allows you to access the table and fields by name (e.g. table[fieldname] ) this also allows aggregate functions on columns e.g. max and average
So I know this is a rapidly changing field but (as of 2015-09-08) I found the following in the Docker Registry HTTP API V2:
GET /v2/_catalog
GET /v2/<name>/tags/list
Based on that the following worked for me on a local registry (registry:2 IMAGE ID 1e847b14150e365a95d76a9cc6b71cd67ca89905e3a0400fa44381ecf00890e1 created on 2015-08-25T07:55:17.072):

I looked into this before buying a Mac Mini. The answer is, essentially, no. You pretty much have to buy a Leopard Mac to do iPhone SDK development for apps that run on non-jailbroken iPhones.
Not that it's 100% impossible, but it's 99.99% unreasonable. Like changing light bulbs with your feet.
Not only do you have to be in Xcode, but you have to get certificates into the Keychain manager to be able to have Xcode and the iPhone communicate. And you have to set all kinds of setting in Xcode just right.
This also works:
zip(*elements)[1]
(I am mainly posting this, to prove to myself that I have groked zip
...)
See it in action:
>>> help(zip)
Help on built-in function zip in module builtin:
zip(...)
zip(seq1 [, seq2 [...]]) -> [(seq1[0], seq2[0] ...), (...)]
Return a list of tuples, where each tuple contains the i-th element from each of the argument sequences. The returned list is truncated in length to the length of the shortest argument sequence.
>>> elements = [(1,1,1),(2,3,7),(3,5,10)]
>>> zip(*elements)
[(1, 2, 3), (1, 3, 5), (1, 7, 10)]
>>> zip(*elements)[1]
(1, 3, 5)
>>>
Neat thing I learned today: Use *list
in arguments to create a parameter list for a function...
Note: In Python3, zip
returns an iterator, so instead use list(zip(*elements))
to return a list of tuples.
On OSX with a homebrew install the full path to the opencv folder should work:
face_cascade = cv2.CascadeClassifier('/usr/local/Cellar/opencv/3.4.0_1/share/OpenCV/haarcascades/haarcascade_frontalface_default.xml')
eye_cascade = cv2.CascadeClassifier('/usr/local/Cellar/opencv/3.4.0_1/share/OpenCV/haarcascades/haarcascade_eye.xml')
Take care of the version number in the path.
In IIS Manager, I added a binding to the site specifying the IP address. Previously, all my bindings were host names.
For me, the problem was caused not by the app in development itself but by the Chrome extension: React Developer Tool. I solved partially that by right-clicking the extension icon in the toolbar, clicking "manage extension" (I'm freely translating menu text here since my browser language is in Brazilian Portuguese), then enabling "Allow access to files URLs." But this measure fixed just some of the alerts.
I found issues in the react repo that suggests the cause is a bug in their extension and is planned to be corrected soon - see issues 20091 and 20075.
You can confirm is extension-related by accessing your app in an anonymous tab without any extension enabled.

I found the following explanation from https://javascript.info/array very helpful:
One of the oldest ways to cycle array items is the for loop over indexes:
let arr = ["Apple", "Orange", "Pear"];
for (let i = 0; i < arr.length; i++) { alert( arr[i] ); } But for arrays there is another form of loop, for..of:
let fruits = ["Apple", "Orange", "Plum"];
// iterates over array elements for (let fruit of fruits) { alert( fruit ); } The for..of doesn’t give access to the number of the current element, just its value, but in most cases that’s enough. And it’s shorter.
Technically, because arrays are objects, it is also possible to use for..in:
let arr = ["Apple", "Orange", "Pear"];
for (let key in arr) { alert( arr[key] ); // Apple, Orange, Pear } But that’s actually a bad idea. There are potential problems with it:
The loop for..in iterates over all properties, not only the numeric ones.
There are so-called “array-like” objects in the browser and in other environments, that look like arrays. That is, they have length and indexes properties, but they may also have other non-numeric properties and methods, which we usually don’t need. The for..in loop will list them though. So if we need to work with array-like objects, then these “extra” properties can become a problem.
The for..in loop is optimized for generic objects, not arrays, and thus is 10-100 times slower. Of course, it’s still very fast. The speedup may only matter in bottlenecks. But still we should be aware of the difference.
Generally, we shouldn’t use for..in for arrays.

let menuButton = UIBarButtonItem(image: menuButtonImage, style: .plain, target: self, action: #selector(didTapMenuButton))

Use SHOW VARIABLES
:
I was using CakePHP and I was seeing this error:
This page isn’t working
localhost is currently unable to handle this request.
HTTP ERROR 500
I went to see the CakePHP Debug Level defined at app\config\core.php:
/**
* CakePHP Debug Level:
*
* Production Mode:
* 0: No error messages, errors, or warnings shown. Flash messages redirect.
*
* Development Mode:
* 1: Errors and warnings shown, model caches refreshed, flash messages halted.
* 2: As in 1, but also with full debug messages and SQL output.
* 3: As in 2, but also with full controller dump.
*
* In production mode, flash messages redirect after a time interval.
* In development mode, you need to click the flash message to continue.
*/
Configure::write('debug', 0);
I chanted the value from 0 to 1:
Configure::write('debug', 1);
After this change, when trying to reload the page again, I saw the corresponding error:
Fatal error: Uncaught Exception: Facebook needs the CURL PHP extension.
Conclusion: The solution in my case to see the errors was to change the CakePHP Debug Level from 0 to 1 in order to show errors and warnings.
A rather roundabout way, just for completeness:
for /f "delims=" %i in ('type CON') do set inp=%i
Of course that requires ^Z as a terminator, and so the Johannes answer is better in all practical ways.
Direct value
should work just fine:
var sv = sel.value;
alert(sv);
The only reason your code might fail is when there is no item selected, then the selectedIndex
returns -1 and the code breaks.
Summarizing all together, here is a universal function (including ie8 support):
var objSize = function(obj) {_x000D_
var count = 0;_x000D_
_x000D_
if (typeof obj == "object") {_x000D_
_x000D_
if (Object.keys) {_x000D_
count = Object.keys(obj).length;_x000D_
} else if (window._) {_x000D_
count = _.keys(obj).length;_x000D_
} else if (window.$) {_x000D_
count = $.map(obj, function() { return 1; }).length;_x000D_
} else {_x000D_
for (var key in obj) if (obj.hasOwnProperty(key)) count++;_x000D_
}_x000D_
_x000D_
}_x000D_
_x000D_
return count;_x000D_
};_x000D_
_x000D_
document.write(objSize({ a: 1, b: 2, c: 3 }));_x000D_
// 3
_x000D_
insert a new column and put a series in 1,2,3,4, etc. Then create another new column and use the command =if(int(a1/7)=(a1/7),1,0) you should get a 1 in every 7th row, filter the column on the 1
Another take on this that hasn't been mentioned here is that, when in debug, the project may build, but it won't run, giving the error message displayed in the question.
If this is the case, another option to look at is the output file versus the target file. These should match.
A quick way to check the output file is to go to the project's property pages, then go to Configuration Properties -> Linker -> General (In VS 2013 - exact path may vary depending on IDE version).
There is an "Output File" setting. If it is not $(OutDir)$(TargetName)$(TargetExt)
, then you may run into issues.
This is also discussed in more detail here.
You can use a script from udhos/update-golang
.
Here is a two-liner as example (run as root
):
bash <(curl -s https://raw.githubusercontent.com/udhos/update-golang/master/update-golang.sh)
ln -vs /usr/local/go/bin/go* /usr/local/bin/
You can download the wheel corresponding to your configuration here ("Pillow-4.1.1-cp36-cp36m-win_amd64.whl" in your case) and install it with:
pip install some-package.whl
If you have problem to install the wheel read this answer
List<String> stringList = new ArrayList<String>(Arrays.asList(arr.split(",")));
List<Integer> intList = new ArrayList<Integer>();
for (String s : stringList)
intList.add(Integer.valueOf(s));
The typical pattern in this situation is to pass the elements in a comma delimited list, and then in SQL split that out into a table you can use. Most people usually create a specified function for doing this like:
INSERT INTO <SomeTempTable>
SELECT item FROM dbo.SplitCommaString(@myParameter)
And then you can use it in other queries.
We are using HTTPClient 4.3.5 and we tried almost all solutions exist on the stackoverflow but nothing, After thinking and figuring out the problem, we come to the following code which works perfectly, just add it before creating HttpClient instance.
some method to call when making post requests....
SSLContextBuilder builder = new SSLContextBuilder();
builder.loadTrustMaterial(null, new TrustStrategy() {
@Override
public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
return true;
}
});
SSLConnectionSocketFactory sslSF = new SSLConnectionSocketFactory(builder.build(),
SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
HttpClient httpClient = HttpClients.custom().setSSLSocketFactory(sslSF).build();
HttpPost postRequest = new HttpPost(url);
continue your request in the normal form

It might be better to use communicate
:
from subprocess import Popen, PIPE, STDOUT
p = Popen(['myapp'], stdout=PIPE, stdin=PIPE, stderr=PIPE)
stdout_data = p.communicate(input='data_to_write')[0]
"Better", because of this warning:
Use communicate() rather than .stdin.write, .stdout.read or .stderr.read to avoid deadlocks due to any of the other OS pipe buffers filling up and blocking the child process.
An attempt to find the first would be:
$first = true;
foreach ( $obj as $value )
{
if ( $first )
{
// do something
$first = false; //in order not to get into the if statement for the next loops
}
else
{
// do something else for all loops except the first
}
}
This is a very old thread, but I am missing another in my opinion convenient solution:
I never revert a merge. I just create another branch from the revision where everything was ok and then cherry pick everything that needs to picked from the old branch which was added in between.
So, if the GIT history is like this:
I create a new branch from a, cherry pick c and d and then the new branch is clear from b. I can ever decide to do the merge of "b" in my new branch again. The old branch becomes deprecated and will be deleted if "b" is not necessary anymore or still in another (feature/hotfix) branch.
The only problem is now one of the very hardest things in computer science: How do you name the new branch? ;)
Ok, if you failed esp. in devel, you create newdevel as mentioned above, delete old devel and rename newdevel to devel. Mission accomplished. You can now merge the changes again when you want. It is like never merged before....
The getParent
method returns a ViewParent
, not a View
. You need to cast the first call to getParent()
also:
RelativeLayout r = (RelativeLayout) ((ViewGroup) this.getParent()).getParent();
As stated in the comments by the OP, this is causing a NPE
. To debug, split this up into multiple parts:
ViewParent parent = this.getParent();
RelativeLayout r;
if (parent == null) {
Log.d("TEST", "this.getParent() is null");
}
else {
if (parent instanceof ViewGroup) {
ViewParent grandparent = ((ViewGroup) parent).getParent();
if (grandparent == null) {
Log.d("TEST", "((ViewGroup) this.getParent()).getParent() is null");
}
else {
if (parent instanceof RelativeLayout) {
r = (RelativeLayout) grandparent;
}
else {
Log.d("TEST", "((ViewGroup) this.getParent()).getParent() is not a RelativeLayout");
}
}
}
else {
Log.d("TEST", "this.getParent() is not a ViewGroup");
}
}
//now r is set to the desired RelativeLayout.
I think this should be a comment or an edit to ThinkingMedia's answer on this very question (Check free disk space for current partition in bash), but I am not allowed to comment (not enough rep) and my edit has been rejected (reason: "this should be a comment or an answer"). So please, powers of the SO universe, don't damn me for repeating and fixing someone else's "answer". But someone on the internet was wrong!™ and they wouldn't let me fix it.
The code
df --output=avail -h "$PWD" | sed '1d;s/[^0-9]//g'
has a substantial flaw:
Yes, it will output 50G
free as 50 -- but it will also output 5.0M
free as 50 or 3.4G
free as 34 or 15K
free as 15.
To create a script with the purpose of checking for a certain amount of free disk space you have to know the unit you're checking against. Remove it (as sed
does in the example above) the numbers don't make sense anymore.
If you actually want it to work, you will have to do something like:
FREE=`df -k --output=avail "$PWD" | tail -n1` # df -k not df -h
if [[ $FREE -lt 10485760 ]]; then # 10G = 10*1024*1024k
# less than 10GBs free!
fi;
Also for an installer to df -k $INSTALL_TARGET_DIRECTORY
might make more sense than df -k "$PWD"
.
Finally, please note that the --output
flag is not available in every version of df / linux.
What I believe you're looking for is a way to work with arrays as object values:
var o = {} // empty Object
var key = 'Orientation Sensor';
o[key] = []; // empty Array, which you can push() values into
var data = {
sampleTime: '1450632410296',
data: '76.36731:3.4651554:0.5665419'
};
var data2 = {
sampleTime: '1450632410296',
data: '78.15431:0.5247617:-0.20050584'
};
o[key].push(data);
o[key].push(data2);
This is standard JavaScript and not something NodeJS specific. In order to serialize it to a JSON string you can use the native JSON.stringify
:
JSON.stringify(o);
//> '{"Orientation Sensor":[{"sampleTime":"1450632410296","data":"76.36731:3.4651554:0.5665419"},{"sampleTime":"1450632410296","data":"78.15431:0.5247617:-0.20050584"}]}'
Most Previous answers were correct but here is the answer and example for Python 3.7. Yes, you can create an abstract class and method. Just as a reminder sometimes a class should define a method which logically belongs to a class, but that class cannot specify how to implement the method. For example, in the below Parents and Babies classes they both eat but the implementation will be different for each because babies and parents eat a different kind of food and the number of times they eat is different. So, eat method subclasses overrides AbstractClass.eat.
from abc import ABC, abstractmethod
class AbstractClass(ABC):
def __init__(self, value):
self.value = value
super().__init__()
@abstractmethod
def eat(self):
pass
class Parents(AbstractClass):
def eat(self):
return "eat solid food "+ str(self.value) + " times each day"
class Babies(AbstractClass):
def eat(self):
return "Milk only "+ str(self.value) + " times or more each day"
food = 3
mom = Parents(food)
print("moms ----------")
print(mom.eat())
infant = Babies(food)
print("infants ----------")
print(infant.eat())
OUTPUT:
moms ----------
eat solid food 3 times each day
infants ----------
Milk only 3 times or more each day
The definition of PHP_EOL is that it gives you the newline character of the operating system you're working on.
In practice, you should almost never need this. Consider a few cases:
When you are outputting to the web, there really isn't any convention except that you should be consistent. Since most servers are Unixy, you'll want to use a "\n" anyway.
If you're outputting to a file, PHP_EOL might seem like a good idea. However, you can get a similar effect by having a literal newline inside your file, and this will help you out if you're trying to run some CRLF formatted files on Unix without clobbering existing newlines (as a guy with a dual-boot system, I can say that I prefer the latter behavior)
PHP_EOL is so ridiculously long that it's really not worth using it.
Try an OUTER APPLY
SELECT
C.Content_ID,
C.Content_Title,
C.Content_DatePublished,
M.Media_Id
FROM
tbl_Contents C
OUTER APPLY
(
SELECT TOP 1 *
FROM tbl_Media M
WHERE M.Content_Id = C.Content_Id
) m
ORDER BY
C.Content_DatePublished ASC
Alternatively, you could GROUP BY
the results
SELECT
C.Content_ID,
C.Content_Title,
C.Content_DatePublished,
M.Media_Id
FROM
tbl_Contents C
LEFT OUTER JOIN tbl_Media M ON M.Content_Id = C.Content_Id
GROUP BY
C.Content_ID,
C.Content_Title,
C.Content_DatePublished,
M.Media_Id
ORDER BY
C.Content_DatePublished ASC
The OUTER APPLY
selects a single row (or none) that matches each row from the left table.
The GROUP BY
performs the entire join, but then collapses the final result rows on the provided columns.
here's another way using the Array includes() method:
[undefined, null].includes(value)

sort
method has been deprecated and replaced with sort_values
. After converting to datetime object using df['Date']=pd.to_datetime(df['Date'])
df.sort_values(by=['Date'])
Note: to sort in-place and/or in a descending order (the most recent first):
df.sort_values(by=['Date'], inplace=True, ascending=False)
Just a slight addition to the above solution if you are having problem with downloaded file's name...
Response.AddHeader("Content-Disposition", "attachment; filename=\"" + file.Name + "\"");
This will return the exact file name even if it contains spaces or other characters.
This can be the message you receive even when custom errors is turned off in web.config file. It can mean you have run out of free space on the drive that hosts the application. Clean your log files if you have no other space to gain on the drive.
You can use .is(':visible')
Selects all elements that are visible.
For example:
if($('#selectDiv').is(':visible')){
Also, you can get the div which is visible by:
$('div:visible').callYourFunction();
Live example:
console.log($('#selectDiv').is(':visible'));_x000D_
console.log($('#visibleDiv').is(':visible'));
_x000D_
#selectDiv {_x000D_
display: none; _x000D_
}
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="selectDiv"></div>_x000D_
<div id="visibleDiv"></div>

You can't effectively use Distinct
on a collection of objects (without additional work). I will explain why.
It uses the default equality comparer,
Default
, to compare values.
For objects that means it uses the default equation method to compare objects (source). That is on their hash code. And since your objects don't implement the GetHashCode()
and Equals
methods, it will check on the reference of the object, which are not distinct.
at new chrome version (maybe 67.0.3396.62) , CSS hex color can use this model display,
eg:

cc is opacity , but old chrome not support that mod
A little late to this party - but this also works well:
CREATE VIEW [ABC].[View_SomeDataUniqueKey]
AS
SELECT
CAST(CONCAT(CAST([ID] AS VARCHAR(4)),
CAST(ROW_NUMBER() OVER(ORDER BY [ID] ASC) as VARCHAR(4))
) AS int) AS [UniqueId]
,[ID]
FROM SOME_TABLE JOIN SOME_OTHER_TABLE
GO
In my case the join resulted in [ID] - the primary key being repeated up to 5 times (associated different unique data) The nice trick with this is that the original ID can be determined from each UniqueID effectively [ID]+RowNumber() = 11, 12, 13, 14, 21, 22, 23, 24 etc. If you add RowNumber() and [ID] back into the view - you can easily determine your original key from the data. But - this is not something that should be committed to a table because I am fairly sure that the RowNumber() of a view will never be reliably the same as the underlying data alters, even with the OVER(ORDER BY [ID] ASC) to try and help it.
Example output ( Select UniqueId, ID, ROWNR, Name from [REF].[View_Systems] ) :
UniqueId ID ROWNR Name

,ROW_NUMBER() OVER(ORDER BY TABA.[ID] ASC) AS ROWNR

You can use this Javascript :
function getParameterByName(name) {
var match = RegExp('[?&]' + name + '=([^&]*)').exec(window.location.search);
return match && decodeURIComponent(match[1].replace(/\+/g, ' '));
}
You can also use the plugin jQuery-URL-Parser allows to retrieve all parts of URL, including anchor, host, etc.
Usage is very simple and cool:
$.url().param("itemID")

Well, if you really want to show the memory peak and some more in-depth statistics i recommend using a profiler such as valgrind. A nice valgrind front-end is alleyoop.
private class GetProfileRequestAsyncTasks extends AsyncTask<String, Void, JSONObject> {
@Override
protected void onPreExecute() {
}
@Override
protected JSONObject doInBackground(String... urls) {
if (urls.length > 0) {
String url = urls[0];
HttpClient httpClient = new DefaultHttpClient();
HttpGet httpget = new HttpGet(url);
httpget.setHeader("x-li-format", "json");
try {
HttpResponse response = httpClient.execute(httpget);
if (response != null) {
//If status is OK 200
if (response.getStatusLine().getStatusCode() == 200) {
String result = EntityUtils.toString(response.getEntity());
//Convert the string result to a JSON Object
return new JSONObject(result);
}
}
} catch (IOException e) {
} catch (JSONException e) {
}
}
return null;
}
@Override
protected void onPostExecute(JSONObject data) {
if (data != null) {
Log.d(TAG, String.valueOf(data));
}
}
}
You can use simple print statements, or any other way of writing to stdout. You can also invoke the Python debugger anywhere in your tests.
If you use nose to run your tests (which I recommend), it will collect the stdout for each test and only show it to you if the test failed, so you don't have to live with the cluttered output when the tests pass.
nose also has switches to automatically show variables mentioned in asserts, or to invoke the debugger on failed tests. For example -s
(--nocapture
) prevents the capture of stdout.
Well, there are many solutions already given above. If there are none of them works, maybe you should just try to reset your password again to 'root' as described here, and then reopen http://localhost/phpMyAdmin/
in other browser. At least this solution works for me.
Try adding System.Web

...better is declare the name as varible ,and ask before if thereis a apostrophe in the string:
e.g.:

YourName = "Daniel O'Neal"
If InStr(YourName, "'") Then
SELECT * FROM tblStudents WHERE [name] Like """ Your Name """ ;
else
SELECT * FROM tblStudents WHERE [name] Like '" Your Name "' ;

For people running Android Studio
and Eclipse
:
I know that answers are already saturated, but I'll just add that it appears that this error surfaces after installing Android Studio and returning to Eclipse to build and run your project.
Make sure you close all other instances of ADB that may be running (including Android Studio). Once you've done this if you are still having troubles try killing all ADB server processes and restarting. If you haven't setup a global variable, open terminal and navigate to the platform-tools folder of the Android SDK Eclipse is referencing, then run:
./adb kill-server
./adb start-server
You could assign the comparison of the property to "1"
obj["isChecked"] = (obj["isChecked"]==="1");
This only evaluates for a String value of "1"
though. Other variables evaulate to false like an actual typeof number
would be false. (i.e. obj["isChecked"]=1
)
If you wanted to be indiscrimate about "1"
or 1
, you could use:
obj["isChecked"] = (obj["isChecked"]=="1");
console.log(obj["isChecked"]==="1"); // true
console.log(obj["isChecked"]===1); // false
console.log(obj["isChecked"]==1); // true
console.log(obj["isChecked"]==="0"); // false
console.log(obj["isChecked"]==="Elephant"); // false
Same concept in PHP
$obj["isChecked"] = ($obj["isChecked"] == "1");
The same operator limitations as stated above for JavaScript apply.
The 'double not' also works. It's confusing when people first read it but it works in both languages for integer/number type values. It however does not work in JavaScript for string type values as they always evaluate to true:
!!"1"; //true
!!"0"; //true
!!1; //true
!!0; //false
!!parseInt("0",10); // false
echo !!"1"; //true
echo !!"0"; //false
echo !!1; //true
echo !!0; //false

possible followed by some command like untabify
or tabs2spaces
For Single valued associations, i.e.-One-to-One and Many-to-One:-
Default Lazy=proxy
Proxy lazy loading:- This implies a proxy object of your associated entity is loaded. This means that only the id connecting the two entities is loaded for the proxy object of associated entity.
Eg: A and B are two entities with Many to one association. ie: There may be multiple A's for every B. Every object of A will contain a reference of B.
`
public class A{
int aid;
//some other A parameters;
B b;
}
public class B{
int bid;
//some other B parameters;
}
`
The relation A will contain columns(aid,bid,...other columns of entity A).
The relation B will contain columns(bid,...other columns of entity B)
Proxy implies when A is fetched, only id is fetched for B and stored into a proxy object of B which contains only id.
Proxy object of B is a an object of a proxy-class which is a subclass of B with only minimal fields.
Since bid is already part of relation A, it is not necessary to fire a query to get bid from the relation B.
Other attributes of entity B are lazily loaded only when a field other than bid is accessed.
For Collections, i.e.-Many-to-Many and One-to-Many:-
Default Lazy=true
Please also note that the fetch strategy(select,join etc) can override lazy.
ie: If lazy='true' and fetch='join', fetching of A will also fetch B or Bs(In case of collections). You can get the reason if you think about it.
Default fetch for single valued association is "join".
Default fetch for collections is "select".
Please verify the last two lines. I have deduced that logically.
I have created a ultimate small js npm library for the base64 encode/decode conversion in Node.js.
npm install nodejs-base64-converter --save
var nodeBase64 = require('nodejs-base64-converter');

console.log(nodeBase64.decode("dGVzdCB0ZXh0")); //test text
I suspect you're facing the issue where your package.json
file is not in the same directory as your Gruntfile.js
. When you run your grunt xxx
commands, you get error an message like:
Local Npm module "xxx" not found. Is it installed?
For now, the solution is:
npm install
to load them locallyIMHO, it is sad that we cannot have grunt resolve modules loaded from a parent npm module (i.e. package.json in a parent directory within the same project). The discussion here seems to indicate that it was done to avoid loading "global" modules but I think what we want is loading from "my project" modules instead.

Just a comment on the method of accomplishing this:
You're making your EntryForm permanently tied to the form you're calling it from. I think it's better to not have forms tied to context like that. I'd remove the requery from the Save/Close routine and instead open the EntryForm modally, using the acDialog switch:
DoCmd.OpenForm "EntryForm", , ,"[ID]=" & Me!SubForm.Form!ID, , acDialog
Me!SubForm.Form.Requery
That way, EntryForm is not tied down to use in one context. The alternative is to complicate EntryForm with something that is knowledgable of which form opened it and what needs to requeried. I think it's better to keep that kind of thing as close to the context in which it's used, and keep the called form's code as simple as possible.
Perhaps a principle here is that any time you are requerying a form using the Forms collection from another form, it's a good indication something's not right about your architecture -- that should happen seldom, in my opinion.
This kind of error can also happen when using COPY and having an escaped string containing NULL values(00
) such as:
"H\x00\x00\x00tj\xA8\x9E#D\x98+\xCA\xF0\xA7\xBBl\xC5\x19\xD7\x8D\xB6\x18\xEDJ\x1En"
If you use COPY
without specifying the format 'CSV'
postgres by default will assume format 'text'
. This has a different interaction with backlashes, see text format.
If you're using COPY
or a file_fdw
make sure to specify format 'CSV'
to avoid this kind of errors.
based from the answer of @SW4, you could also add a little animation at the end.

Making the remaining 0.5 seconds to animate the opacity attribute. Just make sure to do the math if you're changing the length, in this case, 90% of 5 seconds leaves us 0.5 seconds to animate the opacity.
This works for displaying purposes:
set(gca(), 'LooseInset', get(gca(), 'TightInset'));
Should work for printing as well.
If even after repeated upload you still get timeout error, pleasechange your settings in
\phpmyadmin\libraries\config.default.php
from $cfg['ExecTimeLimit'] = 300;
to $cfg['ExecTimeLimit'] = 0;
and restart. Now there is no execution time limit (trust we are talking about local server).

Slightly different option usually works for me:

To repair a corrupt database you can use the sqlite3 commandline utility. Type in the following commands in a shell after setting the environment variables:
cd $DATABASE_LOCATION
echo '.dump'|sqlite3 $DB_NAME|sqlite3 repaired_$DB_NAME
mv $DB_NAME corrupt_$DB_NAME
mv repaired_$DB_NAME $DB_NAME
This code helped me recover a SQLite database I use as a persistent store for Core Data and which produced the following error upon save:
Could not save: NSError 259 in Domain NSCocoaErrorDomain { NSFilePath = mydata.db NSUnderlyingException = Fatal error. The database at mydata.db is corrupted. SQLite error code:11, 'database disk image is malformed' }
wget -O yourfilename.zip remote-storage.url/theirfilename.zip
will do the trick for you.
Note:
a) its a capital O.
b) wget -O filename url
will only work. Putting -O
last will not.
If you wish to go to the login page of phpmyadmin, click the "exit" button (the second one from left to right under the main logo "phpmyadmin").
It worked for me with low_memory = False
while importing a DataFrame. That is all the change that worked for me:
df = pd.read_csv('export4_16.csv',low_memory=False)
Use jquery cookie https://github.com/carhartl/jquery-cookie and then you can be sure the class will stay on page refresh.
Stores the id of the clicked element in the cookie and then uses that to add the class on refresh.
//Get cookie value and set active
var tab = $.cookie('active');
$('#' + tab).addClass('active');
//Set cookie active tab value on click
//Done this way to preserve after page refresh
$('.topTab').click(function (event) {
var clickedTab = event.target.id;
$.removeCookie('active', { path: '/' });
$( '.active' ).removeClass( 'active' );
$.cookie('active', clickedTab, { path: '/' });
});
Louis' answer is great, but I thought I would try to sum it up succinctly:
The bang operator tells the compiler to temporarily relax the "not null" constraint that it might otherwise demand. It says to the compiler: "As the developer, I know better than you that this variable cannot be null right now".
Postgres hasn't implemented an equivalent to INSERT OR REPLACE
. From the ON CONFLICT
docs (emphasis mine):
It can be either DO NOTHING, or a DO UPDATE clause specifying the exact details of the UPDATE action to be performed in case of a conflict.
Though it doesn't give you shorthand for replacement, ON CONFLICT DO UPDATE
applies more generally, since it lets you set new values based on preexisting data. For example:
INSERT INTO users (id, level)
VALUES (1, 0)
ON CONFLICT (id) DO UPDATE
SET level = users.level + 1;
Running git pull
performs the following tasks, in order:
git fetch
git merge
The merge step combines branches that have been setup to be merged in your config. You want to undo the merge step, but probably not the fetch (doesn't make a lot of sense and shouldn't be necessary).
To undo the merge, use git reset --hard
to reset the local repository to a previous state; use git-reflog to find the SHA-1 of the previous state and then reset to it.
Warning
The commands listed in this section remove all uncommitted changes, potentially leading to a loss of work:
git reset --hard
Alternatively, reset to a particular point in time, such as:
git reset --hard master@{"10 minutes ago"}
You could pass in the command-line option -v
with a variable name (v
) and a value (=
) of the environment variable ("${v}"
):
% awk -vv="${v}" 'BEGIN { print v }'
123test
Or to make it clearer (with far fewer v
s):
% environment_variable=123test
% awk -vawk_variable="${environment_variable}" 'BEGIN { print awk_variable }'
123test
All of the answers above are correct, for the case of DISTINCT on a single column vs GROUP BY on a single column. Every db engine has its own implementation and optimizations, and if you care about the very little difference (in most cases) then you have to test against specific server AND specific version! As implementations may change...
BUT, if you select more than one column in the query, then the DISTINCT is essentially different! Because in this case it will compare ALL columns of all rows, instead of just one column.
So if you have something like:
// This will NOT return unique by [id], but unique by (id,name)
SELECT DISTINCT id, name FROM some_query_with_joins
// This will select unique by [id].
SELECT id, name FROM some_query_with_joins GROUP BY id
It is a common mistake to think that DISTINCT keyword distinguishes rows by the first column you specified, but the DISTINCT is a general keyword in this manner.
So people you have to be careful not to take the answers above as correct for all cases... You might get confused and get the wrong results while all you wanted was to optimize!

Hi there is a way to write and read the dictionary to file you can turn your dictionary to JSON format and read and write quickly just do this :
To write your date:
import json
your_dictionary = {"some_date" : "date"}
f = open('destFile.txt', 'w+')
f.write(json.dumps(your_dictionary))
and to read your data:
import json
f = open('destFile.txt', 'r')
your_dictionary = json.loads(f.read())
If you know, or can enforce the size for the to-be-upper element, you could use
position : absolute;
In your css and give the divs their position.
otherwise javascript seems the only way to go:
fd = document.getElementById( 'firstDiv' );
sd = document.getElementById( 'secondDiv' );
fd.parentNode.removeChild( fd );
sd.parentNode.insertAfter( fd, sd );
or something similar.
edit: I just found this which might be useful: w3 document css3 move-to
This is the simplest way of changing one date format to another
public String changeDateFormatFromAnother(String date){
@SuppressLint("SimpleDateFormat") DateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
@SuppressLint("SimpleDateFormat") DateFormat outputFormat = new SimpleDateFormat("dd MMMM yyyy");
String resultDate = "";
try {
resultDate=outputFormat.format(inputFormat.parse(date));
} catch (ParseException e) {
e.printStackTrace();
}
return resultDate;
}
echo dump | nc localhost 2181 | grep brokers
(replace localhost with the host where zookeeper is running)
I have used following code to escape the string value for json. You need to add your '"' to the output of the following code:
public static string EscapeStringValue(string value)
{
const char BACK_SLASH = '\\';
const char SLASH = '/';
const char DBL_QUOTE = '"';
var output = new StringBuilder(value.Length);
foreach (char c in value)
{
switch (c)
{
case SLASH:
output.AppendFormat("{0}{1}", BACK_SLASH, SLASH);
break;
case BACK_SLASH:
output.AppendFormat("{0}{0}", BACK_SLASH);
break;
case DBL_QUOTE:
output.AppendFormat("{0}{1}",BACK_SLASH,DBL_QUOTE);
break;
default:
output.Append(c);
break;
}
}
return output.ToString();
}
Try this:
var date = new Date();
console.log(date instanceof Date && !isNaN(date.valueOf()));
This should return true
.
UPDATED: Added isNaN

My solution, after trying EVERYTHING:
Bad deployment, an old PrecompiledApp.config was hanging around my deploy location, and making everything not work.
My final settings that worked:
Nothing changes in the web.config - this means no special handlers for routing. Here's my snapshot of the sections a lot of other posts reference. I'm using FluorineFX, so I do have that handler added, but I did not need any others:

<compilation debug="true" targetFramework="4.0" />
<authentication mode="None"/>
<pages validateRequest="false" controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID"/>
<httpRuntime requestPathInvalidCharacters=""/>

<add name="FluorineGateway" type="FluorineFx.FluorineGateway, FluorineFx"/>
</httpModules>
</system.web>

Global.ashx: (only method of any note)
void Application_Start(object sender, EventArgs e) {
// Register routes...
System.Web.Routing.Route echoRoute = new System.Web.Routing.Route(

//the default value for the message
new System.Web.Routing.RouteValueDictionary() { { "message", "" } },
//any regular expression restrictions (i.e. @"[^\d].{4,}" means "does not start with number, at least 4 chars
new System.Web.Routing.RouteValueDictionary() { { "message", @"[^\d].{4,}" } },
new TestRoute.Handlers.PassthroughRouteHandler()
);
System.Web.Routing.RouteTable.Routes.Add(echoRoute);
}
PassthroughRouteHandler.cs - this achieved an automatic conversion from http://andrew.arace.info/stackoverflow to http://andrew.arace.info/#stackoverflow which would then be handled by the default.aspx:
public class PassthroughRouteHandler : IRouteHandler {
public IHttpHandler GetHttpHandler(RequestContext requestContext) {
HttpContext.Current.Items["IncomingMessage"] = requestContext.RouteData.Values["message"];
requestContext.HttpContext.Response.Redirect("#" + HttpContext.Current.Items["IncomingMessage"], true);
return null;
}
}
Similar to the answer pointed out by @Thomas,
This can also be done using ifelse()
method of R:
for(i in 1:ncol(data)){
data[,i]=ifelse(is.na(data[,i]),
ave(data[,i],FUN=function(y) mean(y, na.rm = TRUE)),
data[,i])
}
where,
Arguments to ifelse(TEST, YES , NO)
are:-
TEST- logical condition to be checked
YES- executed if the condition is True
NO- else when the condition is False
and ave(x, ..., FUN = mean)
is method in R used for calculating averages of subsets of x[]
There's no way around it except to store it. Memory paging should reduce potential issues there.
I would suggest instead of using a global variable called 'xml', do something more like this:
var dataStore = (function(){
var xml;
$.ajax({
type: "GET",
url: "test.xml",
dataType: "xml",
success : function(data) {
xml = data;
}
});
return {getXml : function()
{
if (xml) return xml;
// else show some error that it isn't loaded yet;
}};
})();
then access it with:
$(dataStore.getXml()).find('something').attr('somethingElse');
Make sure that you have enter valid detail in application.properties and whether your database server is available. As a example when you are connecting with MySQL check whether XAMPP is running properly.
All the above solutions didn't work in all browsers. Here is what finally works on IE 10+, Firefox and Chrome (and without jQuery or any other library):
save: function(filename, data) {
var blob = new Blob([data], {type: 'text/csv'});
if(window.navigator.msSaveOrOpenBlob) {
window.navigator.msSaveBlob(blob, filename);
}
else{
var elem = window.document.createElement('a');
elem.href = window.URL.createObjectURL(blob);
elem.download = filename;
document.body.appendChild(elem);
elem.click();
document.body.removeChild(elem);
}
}
Note that, depending on your situation, you may also want to call URL.revokeObjectURL after removing elem
. According to the docs for URL.createObjectURL:
Each time you call createObjectURL(), a new object URL is created, even if you've already created one for the same object. Each of these must be released by calling URL.revokeObjectURL() when you no longer need them. Browsers will release these automatically when the document is unloaded; however, for optimal performance and memory usage, if there are safe times when you can explicitly unload them, you should do so.
These are exactly the same. android:onClick
was added in API level 4 to make it easier, more Javascript-web-like, and drive everything from the XML. What it does internally is add an OnClickListener
on the Button, which calls your DoIt
method.
Here is what using a android:onClick="DoIt"
does internally:
Button button= (Button) findViewById(R.id.buttonId);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
DoIt(v);
}
});
The only thing you trade off by using android:onClick
, as usual with XML configuration, is that it becomes a bit more difficult to add dynamic content (programatically, you could decide to add one listener or another depending on your variables). But this is easily defeated by adding your test within the DoIt
method.
Both do the same work as they are used for routing purposes in SPA(Single Page Application).
URLs to controllers and views (HTML partials). It watches $location.url() and tries to map the path to an existing route definition.
HTML
<div ng-view></div>
Above tag will render the template from the $routeProvider.when()
condition which you had mentioned in .config
(configuration phase) of angular
Limitations:-
ng-view
on page$routeProvider
fails. (to achieve that, we need to use directives like ng-include
, ng-switch
, ng-if
, ng-show
, which looks bad to have them in SPA)AngularUI Router is a routing framework for AngularJS, which allows you to organize the parts of your interface into a state machine. UI-Router is organized around states, which may optionally have routes, as well as other behavior, attached.
Multiple & Named Views
Another great feature is the ability to have multiple ui-views in a template.
While multiple parallel views are a powerful feature, you'll often be able to manage your interfaces more effectively by nesting your view
s, and pairing those views with nested states.
HTML
<div ui-view>
<div ui-view='header'></div>
<div ui-view='content'></div>
<div ui-view='footer'></div>
</div>
The majority of ui-router
's power is it can manage nested state & views.
Pros
ui-view
on single pageui-view="some"
of state just by using absolute routing using @
with state name.@
to change ui-view="some"
. This will replace the ui-view
rather than checking if it is nested or not.ui-sref
to create a href
URL dynamically on the basis of URL
mentioned in a state, also you could give a state params in the json
format.For more Information Angular ui-router
For better flexibility with various nested view with states, I'd prefer you to go for ui-router
The best practice would be to create a module separately which has only one method whose task we be to give a logger handler to the the calling method. Save this file as m_logger.py
import logger, logging
def getlogger():
# logger
logger = logging.getLogger(__name__)
logger.setLevel(logging.DEBUG)
# create console handler and set level to debug
#ch = logging.StreamHandler()
ch = logging.FileHandler(r'log.txt')
ch.setLevel(logging.DEBUG)
# create formatter
formatter = logging.Formatter('%(asctime)s - %(levelname)s - %(message)s')
# add formatter to ch
ch.setFormatter(formatter)
# add ch to logger
logger.addHandler(ch)
return logger
Now call the getlogger() method whenever logger handler is needed.
from m_logger import getlogger
logger = getlogger()
logger.info('My mssg')
I'm an early adopter and implemented a mid-large single page application using the Facebook Flux library.
As I'm a little late to the conversation I'll just point out that despite my best hopes Facebook seem to consider their Flux implementation to be a proof of concept and it has never received the attention it deserves.
I'd encourage you to play with it, as it exposes more of the inner working of the Flux architecture which is quite educational, but at the same time it does not provide many of the benefits that libraries like Redux provide (which aren't that important for small projects, but become very valuable for bigger ones).
We have decided that moving forward we will be moving to Redux and I suggest you do the same ;)
Generally you don't..
You ask it to interrupt whatever it is doing using Thread.interrupt() (javadoc link)
A good explanation of why is in the javadoc here (java technote link)
Here's my two solutions for this
1. Store in json files
Just make a json file and get in your component by $http.get()
method. If I was need this very low then it's good and quick.
2. Store by using data services
If you want to store and use in all components or having large usage then it's better to use data service. Like this :
Just create static folder inside src/app
folder.
Create a file named as fuels.ts
into static folder. You can store other static files here also. Let define your data like this. Assuming you having fuels data.
__
export const Fuels {
Fuel: [
{ "id": 1, "type": "A" },
{ "id": 2, "type": "B" },
{ "id": 3, "type": "C" },
{ "id": 4, "type": "D" },
];
}
__
import { Injectable } from "@angular/core";
import { Fuels } from "./static/fuels";
@Injectable()
export class StaticService {
constructor() { }
getFuelData(): Fuels[] {
return Fuels;
}
}`
just import in app.module.ts file like this and change in providers
import { StaticService } from './static.services';
providers: [StaticService]
Now use this as StaticService
in any module.
That's All.
You can use it by easy way, through store
method in your controller
like the below
{{Form::open(['route' => 'user.store', 'files' => true])}}
{{Form::label('user_photo', 'User Photo',['class' => 'control-label'])}}
{{Form::file('user_photo')}}
{{Form::submit('Save', ['class' => 'btn btn-success'])}}
{{Form::close()}}
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
class UserController extends Controller
{
public function store(Request $request)
{
// get current time and append the upload file extension to it,
// then put that name to $photoName variable.
$photoName = time().'.'.$request->user_photo->getClientOriginalExtension();
/*
talk the select file and move it public directory and make avatars
folder if doesn't exsit then give it that unique name.
*/
$request->user_photo->move(public_path('avatars'), $photoName);
}
}
That’s it. Now you can save the $photoName
to the database as a user_photo
field value. You can use asset(‘avatars’)
function in your view and access the photos.
I think the docs aren't wonderful at exposing how to do this. It has been a supported feature for some time, however, and there are some details in this pull request.
So there are three different ways to do this:
Option A) Create a new session with the profile
dev = boto3.session.Session(profile_name='dev')
Option B) Change the profile of the default session in code
boto3.setup_default_session(profile_name='dev')
Option C) Change the profile of the default session with an environment variable
$ AWS_PROFILE=dev ipython
>>> import boto3
>>> s3dev = boto3.resource('s3')
html, body {
min-height: 100%;
}
Will do the trick.
By default, even html and body are only as big as the content they hold, but never more than the width/height of the windows. This can often lead to quite strange results.
You might also want to read http://css-tricks.com/perfect-full-page-background-image/
There are some great ways do achieve a very good and scalable full background image.
The difference is simple: they cause different warning messages to be emitted when compiling:
1156942.c:7:31: warning: format ‘%d’ expects argument of type ‘int’, but argument 2 has type ‘int *’ [-Wformat=]
printf("memory address = %d\n", &a); // prints "memory add=-12"
^
1156942.c:8:31: warning: format ‘%u’ expects argument of type ‘unsigned int’, but argument 2 has type ‘int *’ [-Wformat=]
printf("memory address = %u\n", &a); // prints "memory add=65456"
^
If you pass your pointer as a void*
and use %p
as the conversion specifier, then you get no error message:
#include <stdio.h>
int main()
{
int a = 5;
// check the memory address
printf("memory address = %d\n", &a); /* wrong */
printf("memory address = %u\n", &a); /* wrong */
printf("memory address = %p\n", (void*)&a); /* right */
}
If your requirement is to disable the startDate and endDate dynamically based on one on another you can you this.
$('#date2').datepicker({
todayHighlight: true,
autoclose: true,
format: "dd/mm/yyyy",
clearBtn : true
}).on('show', function(e){
var date = $('#date3').datepicker('getDate');
if(date){
$('#date2').datepicker('setEndDate', date);
}
});
$('#date3').datepicker({
todayHighlight: true,
autoclose: true,
format: "dd/mm/yyyy",
clearBtn : true
}).on('show', function(e){
var date = $('#date2').datepicker('getDate');
if(date){
$('#date3').datepicker('setStartDate', date);
}
});
If your requirement is just disabled past dates then you can use below snippet.
$('#date2').datepicker({
todayHighlight: true,
autoclose: true,
format: "dd/mm/yyyy",
clearBtn : true,
startDate : new Date()
})
If your requirement is just disabled future dates then you can use below snippet.
$('#date2').datepicker({
todayHighlight: true,
autoclose: true,
format: "dd/mm/yyyy",
clearBtn : true,
endDate : new Date()
})
I hope it will help someone.
Note that connection strings are specific to what and how you are connecting to data. These are connecting to the same database but the first is using .NET Framework Data Provider for SQL Server. Integrated Security=True will not work for OleDb.
When in doubt use the Visual Studio Server Explorer Data Connections.
Here is a code I am using and which is working for me.
window.onload = function(){
setTimeout(function(){
var scriptElement=document.createElement('script');
scriptElement.type = 'text/javascript';
scriptElement.src = "vendor/js/jquery.min.js";
document.head.appendChild(scriptElement);
setTimeout(function() {
var scriptElement1=document.createElement('script');
scriptElement1.type = 'text/javascript';
scriptElement1.src = "gallery/js/lc_lightbox.lite.min.js";
document.head.appendChild(scriptElement1);
}, 100);
setTimeout(function() {
$(document).ready(function(e){
lc_lightbox('.elem', {
wrap_class: 'lcl_fade_oc',
gallery : true,
thumb_attr: 'data-lcl-thumb',
slideshow_time : 3000,
skin: 'minimal',
radius: 0,
padding : 0,
border_w: 0,
});
});
}, 200);
}, 150);
};
VBA has the collection object:
Dim c As Collection
Set c = New Collection
c.Add "Data1", "Key1"
c.Add "Data2", "Key2"
c.Add "Data3", "Key3"
'Insert data via key into cell A1
Range("A1").Value = c.Item("Key2")
The Collection
object performs key-based lookups using a hash so it's quick.
You can use a Contains()
function to check whether a particular collection contains a key:
Public Function Contains(col As Collection, key As Variant) As Boolean
On Error Resume Next
col(key) ' Just try it. If it fails, Err.Number will be nonzero.
Contains = (Err.Number = 0)
Err.Clear
End Function
Edit 24 June 2015: Shorter Contains()
thanks to @TWiStErRob.
Edit 25 September 2015: Added Err.Clear()
thanks to @scipilot.
You tagged your question [C] and [C++] at the same time. The results will be consistent between the languages, but the structure of the the answer is different for each of these languages.
In C language your examples has no relation to bool
whatsoever (that applies to C99 as well). In C language relational operators do not produce bool
results. Both 4 > 5
and 4 < 5
are expressions that produce results of type int
with values 0
or 1
. So, there's no "bool to int conversion" of any kind taking place in your examples in C.
In C++ relational operators do indeed produce bool
results. bool
values are convertible to int
type, with true
converting to 1
and false
converting to 0
. This is guaranteed by the language.
P.S. C language also has a dedicated boolean type _Bool
(macro-aliased as bool
), and its integral conversion rules are essentially the same as in C++. But nevertheless this is not relevant to your specific examples in C. Once again, relational operators in C always produce int
(not bool
) results regardless of the version of the language specification.
You should add a shebang if the script is intended to be executable. You should also install the script with an installing software that modifies the shebang to something correct so it will work on the target platform. Examples of this is distutils and Distribute.
Here's stored procedure, which will generate the table based on data from one table and column and data from other table and column.
The function 'sum(if(col = value, 1,0)) as value ' is used. You can choose from different functions like MAX(if()) etc.
delimiter //
create procedure myPivot(
in tableA varchar(255),
in columnA varchar(255),
in tableB varchar(255),
in columnB varchar(255)
)

set @sql = NULL;
set @sql = CONCAT('select group_concat(distinct concat(
\'SUM(IF(',
columnA,
' = \'\'\',',
columnA,
',\'\'\', 1, 0)) AS \'\'\',',
columnA,
',\'\'\'\') separator \', \') from ',
tableA, ' into @sql');
-- select @sql;
PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
-- select @sql;
SET @sql = CONCAT('SELECT p.',
columnB,

@sql,
' FROM ', tableB, ' p GROUP BY p.',
columnB,'');

C++20 introduced a guarantee that time_since_epoch
is relative to the UNIX epoch, and cppreference.com gives an example that I've distilled to the relevant code, and changed to units of seconds rather than hours:
#include <iostream>
#include <chrono>
int main()
{
const auto p1 = std::chrono::system_clock::now();
std::cout << "seconds since epoch: "
<< std::chrono::duration_cast<std::chrono::seconds>(
p1.time_since_epoch()).count() << '\n';
}
Using C++17 or earlier, time()
is the simplest function - seconds since Epoch, which for Linux and UNIX at least would be the UNIX epoch. Linux manpage here.
The cppreference page linked above gives this example:
#include <ctime>
#include <iostream>
int main()
{
std::time_t result = std::time(nullptr);
std::cout << std::asctime(std::localtime(&result))
<< result << " seconds since the Epoch\n";
}
Window->Preferences->Java->Installed JREs. Then choose your current JRE(JDK) and click Edit. Fill Default VM Arguments: -Djava.library.path=/usr/local/xuggler/lib. Done!
Integer object would be best. If you must use primitives you can use a value that does not exist in your use case. Negative height does not exist for people, so
public int getHeight(String name){
if(map.containsKey(name)){
return map.get(name);
}else{
return -1;
}
}
If you don't mind something related to Bootstrap, an excellent (unofficial) Bootstrap Switch is available.
It uses radio types or checkboxes as switches. A type
attribute has been added since V.1.8.
Source code is available on Github.
I would not recommend to use those kind of old Switch buttons now, as they always seemed to suffer of usability issues as pointed by many people.
Please consider having a look at modern Switches like those.
The answer given by deepak goel does not work for me because I always get null from entry.getName()

What I do is to set a Tag to the fragment this way:
ft.add(R.id.fragment_container, fragmentIn, FRAGMENT_TAG);
Where ft is my fragment transaction and FRAGMENT_TAG
is the tag. Then I use this code to get the fragment:
Fragment prev_fragment = fragmentManager.findFragmentByTag(FRAGMENT_TAG);
The standard way of using merge to undo the entire check-in works great, if that's what you want to do. Sometimes, though, all you want to do is revert a single file. There's no legitimate way to do that, but there is a hack:
Use svn's export subcommand:
svn export http://url-to-your-file@123 /tmp/filename
(Where 123 is the revision number for a good version of the file.) Then either move or copy that single file to overwrite the old one. Check in the modified file and you are done.
If you feel golfy, you can do
eval([123,321,12389]*?+)
This will create a string "123+321+12389" and then use function eval to do the sum. This is only for golfing purpose, you should not use it in proper code.
The simplest solution is to select the second cell, and press =
. This will begin the fomula creation process. Now either type in the 1st cell reference (eg, A1
) or click on the first cell and press enter. This should make the second cell reference the value of the first cell.

In Swift 5 and Xcode 10.2
Basically we have two types of buttons.
1) System type button
2) Custom type button (In custom type button we can set background image for button)
And these two types of buttons has few control states https://developer.apple.com/documentation/uikit/uicontrol/state
Important states are
1) Normal state
2) Selected state
3) Highlighted state
4) Disabled state etc...
//For system type button
let button = UIButton(type: .system)
button.frame = CGRect(x: 100, y: 250, width: 100, height: 50)
// button.backgroundColor = .blue
button.setTitle("Button", for: .normal)
button.setTitleColor(.white, for: .normal)
button.titleLabel?.font = UIFont.boldSystemFont(ofSize: 13.0)
button.titleLabel?.textAlignment = .center//Text alighment center
button.titleLabel?.numberOfLines = 0//To display multiple lines in UIButton
button.titleLabel?.lineBreakMode = .byWordWrapping//By word wrapping
button.tag = 1//To assign tag value
button.btnProperties()//Call UIButton properties from extension function
button.addTarget(self, action:#selector(self.buttonClicked), for: .touchUpInside)
self.view.addSubview(button)
//For custom type button (add image to your button)
let button2 = UIButton(type: .custom)
button2.frame = CGRect(x: 100, y: 400, width: 100, height: 50)
// button2.backgroundColor = .blue
button2.setImage(UIImage.init(named: "img.png"), for: .normal)
button2.tag = 2
button2.btnProperties()//Call UIButton properties from extension function
button2.addTarget(self, action:#selector(self.buttonClicked), for: .touchUpInside)
self.view.addSubview(button2)
@objc func buttonClicked(sender:UIButton) {
print("Button \(sender.tag) clicked")
}
//You can add UIButton properties using extension
extension UIButton {
func btnProperties() {
layer.cornerRadius = 10//Set button corner radious
clipsToBounds = true
backgroundColor = .blue//Set background colour
//titleLabel?.textAlignment = .center//add properties like this
}
}
I'm a little out of touch with the details of how MySQL deals with nulls, but here's two things to try:
SELECT * FROM match WHERE id NOT IN
( SELECT id FROM email WHERE id IS NOT NULL) ;
SELECT
m.*
FROM
match m
LEFT OUTER JOIN email e ON
m.id = e.id
AND e.id IS NOT NULL
WHERE
e.id IS NULL
The second query looks counter intuitive, but it does the join condition and then the where condition. This is the case where joins and where clauses are not equivalent.
I researched Graph API Explorer extensively and finally found full_picture

Well, I guess there is a plethora of circumstances that can trigger this issue. I'm using IntelliJ Idea instead, but it's mostly the same than Android Studio. My solution for this problem:
Fastest way:
Right click on the class file that contains the main activity of your project, and then on "Debug 'WhateverActivity'". This will create a new run configuration that should debug fine.
Other solution, without creating a new run configuration:
- Open Run/Debug configurations and within "Android app" pick the configuration you're using to debug your app.
- Locate "Launch Options/Launch" there and set it to "Specified Activity" instead of "Default Activity".
- In the "Launch" field just below the aforementioned option, click on the three ellipsis (three dots) button and select your main activity.
At least it worked for me. I hope it works for others too.
Normally svn add *
works. But if you get message like svn: warning: W150002:

svn add <path to directory> --force
or
svn add * --force
No need to use jQuery, querystring
or manually assemble the payload. URLSearchParams
is a way to go and here is one of the most concise answers with the full request example:
fetch('https://example.com/login', {
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
},
body: new URLSearchParams({
'param': 'Some value',
'another_param': 'Another value'
})
})
.then(res => {
// Do stuff with the result
});
Yes, you can use Axios or whatever you want instead of fetch
.
P.S. URLSearchParams
is not supported in IE.
What about sending a HEAD request instead of a normal GET request. The following snipped (copied from a similar question) does exactly that.
>>> import httplib
>>> conn = httplib.HTTPConnection("www.google.com")
>>> conn.request("HEAD", "/index.html")
>>> res = conn.getresponse()
>>> print res.status, res.reason
200 OK
>>> print res.getheaders()
[('content-length', '0'), ('expires', '-1'), ('server', 'gws'), ('cache-control', 'private, max-age=0'), ('date', 'Sat, 20 Sep 2008 06:43:36 GMT'), ('content-type', 'text/html; charset=ISO-8859-1')]
You can use
holder.text.setTextColor(Color.rgb(200,0,0));
You can also specify what color you want with Transparency.
holder.text.setTextColor(Color.argb(0,200,0,0));
a for Alpha (Transparent) value r-red g-green b-blue
Not only required
field as mentioned in other answers. Its also caused by placing a <input>
field in a hidden <div>
which holds a invalid value.
Consider below example,
<div style="display:none;">
<input type="number" name="some" min="1" max="50" value="0">
</div>
This throws the same error. So make sure the <input>
fields inside hidden <div>
doesnt hold any invalid value.
The following works for me and tested on Ubuntu 14.04. It is a one liner that does not require any user input.

An absolute URI specifies a scheme; a URI that is not absolute is said to be relative.

For anyone looks for a shorthand way, to add transition for all properties except for one specific property with delay, be aware of there're differences among even modern browsers.
A simple demo below shows the difference. Check out full code
div:hover {
width: 500px;
height: 500px;
border-radius: 0;
transition: all 2s, border-radius 2s 4s;
}
Chrome will "combine" the two animation (which is like I expect), like below:
While Safari "separates" it (which may not be expected):
A more compatible way is that you assign the specific transition for specific property, if you have a delay for one of them.

Adding cors in get function Is what worked for me
What about to split the string and strip words punctuation?
w in [ws.strip(',.?!') for ws in p.split()]
Or working the case:
w.lower() in [ws.strip(',.?!') for ws in p.lower().split()]
Maybe that way:
def wsearch(word, phrase):
# Attention about punctuation and about split characters
punctuation = ',.?!'
return word.lower() in [words.strip(punctuation) for words in phrase.lower().split()]
Sample:
print(wsearch('CAr', 'I own a caR.'))

Remember that the function passed to useMemo runs during rendering. Don’t do anything there that you wouldn’t normally do while rendering. For example, side effects belong in useEffect, not useMemo.
If you want a uniformly distributed pseudorandom long in the range of [0,m
), try using the modulo operator and the absolute value method combined with the nextLong()
method as seen below:
Math.abs(rand.nextLong()) % m;
Where rand
is your Random object.
The modulo operator divides two numbers and outputs the remainder of those numbers. For example, 3 % 2
is 1
because the remainder of 3 and 2 is 1.
Since nextLong()
generates a uniformly distributed pseudorandom long in the range of [-(2^48),2^48) (or somewhere in that range), you will need to take the absolute value of it. If you don't, the modulo of the nextLong()
method has a 50% chance of returning a negative value, which is out of the range [0,m
).
What you initially requested was a uniformly distributed pseudorandom long in the range of [0,100). The following code does so:
Math.abs(rand.nextLong()) % 100;
Under the covers there will be some form of URL loading request. You can't load images or any other content via this method from a local file system.
Your image needs to be loaded via a web server, so accessed via a proper http URL.

cout << M_PI << ", " << M_E << endl;
will yield
3.141592653589793, 2.718281828459045
Why you have to say "+1" I have no clue, but the extra digit you get out of it is correct.
Joining a WORKGROUP then rejoining the domain fixed this issue for me.
I got this error while using Virtual Box VM's. The issue started to happen when I moved the VM files to a new drive location or computer.
Hope this helps the VM folks.
more_itertools
has a tool for sorting iterables in parallel:
Given
from more_itertools import sort_together
X = ["a", "b", "c", "d", "e", "f", "g", "h", "i"]
Y = [ 0, 1, 1, 0, 1, 2, 2, 0, 1]
Demo
sort_together([Y, X])[1]
# ('a', 'd', 'h', 'b', 'c', 'e', 'i', 'f', 'g')
Make sure ~/.ssh/known_hosts
is writable. That fixed it for me.
IMHO Mark Elliot's solution's best one for this problem. If you need to make more complex comparison operations between array elements AND you're on PHP 5.3, you might also think about something like the following:
<?php
// First Array To Compare
$a1 = array('foo','bar','c');
// Target Array
$b1 = array('foo','bar');
// Evaluation Function - we pass guard and target array
$b=true;
$test = function($x) use (&$b, $b1) {
if (!in_array($x,$b1)) {
$b=false;
}
};
// Actual Test on array (can be repeated with others, but guard
// needs to be initialized again, due to by reference assignment above)
array_walk($a1, $test);
var_dump($b);
This relies on a closure; comparison function can become much more powerful. Good luck!
I tried this command to display the list of files in the directory.
dir /s /b > List.txt
In the file it displays the list below.
C:\Program Files (x86)\Cisco Systems\Cisco Jabber\XmppMgr.dll
C:\Program Files (x86)\Cisco Systems\Cisco Jabber\XmppSDK.dll
C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\Plantronics
C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\SennheiserJabberPlugin.dll
C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\Logitech\LogiUCPluginForCisco
C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\Logitech\LogiUCPluginForCisco\lucpcisco.dll
What is want to do is only to display sub-directory not the full directory path.
Just like this:
Cisco Jabber\XmppMgr.dll Cisco Jabber\XmppSDK.dll
Cisco Jabber\accessories\JabraJabberPlugin.dll
Cisco Jabber\accessories\Logitech
Cisco Jabber\accessories\Plantronics
Cisco Jabber\accessories\SennheiserJabberPlugin.dll
In Ubuntu if you execute the script with sh scriptname.sh
you get this problem.
Try executing the script with ./scriptname.sh
instead.
As of 2016, the following will suffice (you don't even need to embed):
let src = 'https://file-examples.com/wp-content/uploads/2017/11/file_example_MP3_700KB.mp3';
let audio = new Audio(src);
audio.play();

After reading your comment on my previous answer I thought I might put this as a separate answer.
Although I appreciate your approach of trying to do it manually to get a better grasp on jQuery I do still emphasise the merit in using existing frameworks.
That said, here is a solution. I've modified some of your css and and HTML just to make it easier for me to work with
WORKING JS FIDDLE - http://jsfiddle.net/HsEne/15/
This is the jQuery
$(document).ready(function(){
$('.sp').first().addClass('active');
$('.sp').hide();
$('.active').show();
$('#button-next').click(function(){
$('.active').removeClass('active').addClass('oldActive');
if ( $('.oldActive').is(':last-child')) {
$('.sp').first().addClass('active');
}
else{
$('.oldActive').next().addClass('active');
}
$('.oldActive').removeClass('oldActive');
$('.sp').fadeOut();
$('.active').fadeIn();
});
$('#button-previous').click(function(){
$('.active').removeClass('active').addClass('oldActive');
if ( $('.oldActive').is(':first-child')) {
$('.sp').last().addClass('active');
}
else{
$('.oldActive').prev().addClass('active');
}
$('.oldActive').removeClass('oldActive');
$('.sp').fadeOut();
$('.active').fadeIn();
});
});
So now the explanation.
Stage 1
1) Load the script on document ready.
2) Grab the first slide and add a class 'active' to it so we know which slide we are dealing with.
3) Hide all slides and show active slide. So now slide #1 is display block and all the rest are display:none;
Stage 2
Working with the button-next click event.
1) Remove the current active class from the slide that will be disappearing and give it the class oldActive so we know that it is on it's way out.
2) Next is an if statement to check if we are at the end of the slideshow and need to return to the start again. It checks if oldActive (i.e. the outgoing slide) is the last child. If it is, then go back to the first child and make it 'active'. If it's not the last child, then just grab the next element (using .next() ) and give it class active.
3) We remove the class oldActive because it's no longer needed.
4) fadeOut all of the slides
5) fade In the active slides
Step 3
Same as in step two but using some reverse logic for traversing through the elements backwards.
It's important to note there are thousands of ways you can achieve this. This is merely my take on the situation.
No you can't use case
and in
like this. But you can do
SELECT * FROM Product P
WHERE @Status='published' and P.Status IN (1,3)
or @Status='standby' and P.Status IN (2,5,9,6)
or @Status='deleted' and P.Status IN (4,5,8,10)
or P.Status IN (1,3)
BTW you can reduce that to
SELECT * FROM Product P
WHERE @Status='standby' and P.Status IN (2,5,9,6)
or @Status='deleted' and P.Status IN (4,5,8,10)
or P.Status IN (1,3)
since or P.Status IN (1,3)
gives you also all records of @Status='published' and P.Status IN (1,3)
In my case the problem was the JAVA_HOME variable was set an installed jre.
An alternative to setting the AS_JAVA variable is to set JAVA_HOME environment variable to the jdk (i.e. /usr/local/jdk1.7.0.51).
Indexing a list is done using double bracket, i.e. hypo_list[[1]]
(e.g. have a look here: http://www.r-tutor.com/r-introduction/list). BTW: read.table
does not return a table but a dataframe (see value section in ?read.table
). So you will have a list of dataframes, rather than a list of table objects. The principal mechanism is identical for tables and dataframes though.
Note: In R, the index for the first entry is a 1
(not 0
like in some other languages).
Dataframes
l <- list(anscombe, iris) # put dfs in list
l[[1]] # returns anscombe dataframe
anscombe[1:2, 2] # access first two rows and second column of dataset
[1] 10 8
l[[1]][1:2, 2] # the same but selecting the dataframe from the list first
[1] 10 8
Table objects
tbl1 <- table(sample(1:5, 50, rep=T))
tbl2 <- table(sample(1:5, 50, rep=T))
l <- list(tbl1, tbl2) # put tables in a list
tbl1[1:2] # access first two elements of table 1
Now with the list
l[[1]] # access first table from the list
1 2 3 4 5
9 11 12 9 9
l[[1]][1:2] # access first two elements in first table
1 2
9 11
Please do not depend on casting as a solution, even though others are suggesting this as a valid option to prevent an error, it might cause another one.
Be aware: If you expect a specific form of array to be returned, this might fail you. More checks are required for that.
E.g. casting a boolean to an array
(array)bool
, will NOT result in an empty array, but an array with one element containing the boolean value as an int:[0=>0]
or[0=>1]
.
I wrote a quick test to present this problem. (Here is a backup Test in case the first test url fails.)
Included are tests for: null
, false
, true
, a class
, an array
and undefined
.
Always test your input before using it in foreach. Suggestions:
$array = is_array($var) or is_object($var) ? $var : [] ;
try{}catch(){}
blocksarray_key_exists
on a specific key, or test the depth of an array (when it is one !).If you are using a mac and sublime text 3, this is what you do.
Go to your /Packages/User/
and create a file called Python.sublime-settings
.
Typically /Packages/User
is inside your ~/Library/Application Support/Sublime Text 3/Packages/User/Python.sublime-settings
if you are using mac os x.
Then you put this in the Python.sublime-settings
.
{
"tab_size": 4,
"translate_tabs_to_spaces": false
}

This answer is mostly for readers who had the same issue and stumble upon this and are using sublime text 3 on Mac OS X.
There are cases where you don't want to use v-model
. If you have two inputs, and each depend on each other, you might have circular referential issues. Common use cases is if you're building an accounting calculator.
In these cases, it's not a good idea to use either watchers or computed properties.
Instead, take your v-model
and split it as above answer indicates
<input
:value="something"
@input="something = $event.target.value"
>
In practice, if you are decoupling your logic this way, you'll probably be calling a method.
