d11701 | train | Because remove is a method that changes the mutable list object it's called on, and returns None.
l= MyWords.upper().split()
l.remove(SpamWords[SpamCheckRange])
# l is ['YES']
Perhaps you want:
>>> [word for word in MyWords.split() if word.upper() not in SpamWords]
['yes']
A: remove is a method of list (str.split returns a list), not str. It mutates the original list (removing what you pass) and returns None, not a modified list. | unknown | |
d11702 | train | I found a good example which works well with twitter4j 3.0.3 on android. Others do not work.
http://hintdesk.com/how-to-tweet-in-twitter-within-android-client/
A: This is the working example from my code , i am using twitter4j and also you don't need to set any intent in manifest since i use webview instead of browser.

A: To illustrate my comment above, here is my final working MainActivity class.
Pretty similar to the code above, the differences are :
*
*the internal class OAuthAccessTokenTask, that includes the retrieval of the Oauth token and the user information
*its callback onRequestTokenRetrieved(Exception)
Also, note that to get this to work you must declare a callback url on your twitter app settings, even a phony one. It took me a few hours to figure out the way it works.
When you check the twitter4j documentation, the first pieces of code refer to a PIN code you have to get from an authorisation webpage. That's what happens when no callback url is set in your app. It's called PIN based authentication and you don't want to use it on a mobile :)

A: I solved the problem. I made changes to the code I found in a tutorial to make it work. Copying the whole code here. Just replace with your ConsumerKey and ConsumerSecret.

d11704 | train | bar = 5 is not an expression. The multiple assignment is a separate statement from the assignment statement; the expression is everything to the right of the right-most =.
A good way to think about it is that the right-most = is the major separator; everything to the right of it happens from left to right, and everything to the left of it happens from left to right as well.
A: All credit goes to @MarkDickinson, who answered this in a comment:
Notice the + in (target_list "=")+, which means one or more copies. In foo = bar = 5, there are two (target_list "=") productions, and the expression_list part is just 5
All target_list productions (i.e. things that look like foo =) in an assignment statement get assigned, from left to right, to the expression_list on the right end of the statement, after the expression_list gets evaluated.
And of course the usual 'tuple-unpacking' assignment syntax works within this syntax, letting you do things like
>>> foo, boo, moo = boo[0], moo[0], foo[0] = moo[0], foo[0], boo[0] = [0], [0], [0]
>>> foo
[[[[...]]]]
>>> foo[0] is boo
True
>>> foo[0][0] is moo
True
>>> foo[0][0][0] is foo
True
A: Mark Dickinson explained the syntax of what is happening, but the weird examples involving foo show that the semantics can be counter-intuitive.
In C, = is a right-associative operator which returns as a value the RHS of the assignment so when you write x = y = 5, y=5 is first evaluated (assigning 5 to y in the process) and this value (5) is then assigned to x.
Before I read this question, I naively assumed that roughly the same thing happens in Python. But, in Python = isn't an expression (for example, 2 + (x = 5) is a syntax error). So Python must achieve multiple assignments in another way.
We can disassemble rather than guess:
>>> import dis
>>> dis.dis('x = y = 5')
1 0 LOAD_CONST 0 (5)
3 DUP_TOP
4 STORE_NAME 0 (x)
7 STORE_NAME 1 (y)
10 LOAD_CONST 1 (None)
13 RETURN_VALUE
See this for a description of the byte code instructions.
The first instruction pushes 5 onto the stack.
The second instruction duplicates it -- so now the top of the stack has two 5s
STORE_NAME(name) "Implements name = TOS" according to the byte code documentation
Thus STORE_Name(x) implements x = 5 (the 5 on top of the stack), popping that 5 off the stack as it goes, after which STORE_Name(y) implements y = 5 with the other 5 on the stack.
The rest of the bytecode isn't directly relevant here.
In the case of foo = foo[0] = [0] the byte-code is more complicated because of the lists but has a fundamentally similar structure. The key observation is that once the list [0] is created and placed on the stack then the instruction DUP_TOP doesn't place another copy of [0] on the stack, instead it places another reference to the list. In other words, at that stage the top two elements of the stack are aliases for the same list. This can be seen most clearly in the somewhat simpler case:
>>> x = y = [0]
>>> x[0] = 5
>>> y[0]
5
When foo = foo[0] = [0] is executed, the list [0] is first assigned to foo and then an alias of the same list is assigned to foo[0]. This is why it results in foo being a circular reference.
A: https://docs.python.org/3/reference/simple_stmts.html#grammar-token-assignment_stmt
An assignment statement evaluates the expression list (remember that this can be a single expression or a comma-separated list, the latter yielding a tuple) and assigns the single resulting object to each of the target lists, from left to right.
A: The assignment order is that right most value is assigned to the first variable from left to right. Please note below:
>>> foo[0] = foo = [1,2,3] # line 1
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'foo' is not defined
>>> foo = foo[0] = [1,2,3] # line 2
>>> foo
[[...], 2, 3]
The assignment at line 1 fails because it is trying assign a value to foo[0] but foo is never initialized or defined so it fails.
The assignment at line 2 works because foo is first initialized to be [1,2,3] and then foo[0] is assigned [1,2,3] | unknown | |
d11705 | train | In a class definition, Python transforms __x into _classname__x. This is called name mangling. Its purpose is to support class local references so that subclasses don't unintentionally break the internal logic of the parent class.
A: Cause
This is due to Python's name mangling of class attribute names that start with __ and are suffixed with at most a single _. This suggests a stricter privacy for these attributes.
Note: This is still a heuristic and shouldn't be counted on for access prevention.
From the docs:
Any identifier of the form __spam (at least two leading underscores, at most one trailing underscore) is textually replaced with _classname__spam, where classname is the current class name with leading underscore(s) stripped.
class A:
def __foo_(self): pass
print(vars(A))
outputs
{'__module__': '__main__', '_A__foo_': <function A.__foo_ at 0x1118c2488>, '__dict__': <attribute '__dict__' of 'A' objects>, '__weakref__': <attribute '__weakref__' of 'A' objects>, '__doc__': None}
Notice that __foo_ has been mangled into _A__foo_.
Uses
Why might this be useful? Well the example from the docs is pretty compelling:
Name mangling is helpful for letting subclasses override methods without breaking intraclass method calls. For example:
class Mapping:
def __init__(self, iterable):
self.items_list = []
self.__update(iterable)
def update(self, iterable):
for item in iterable:
self.items_list.append(item)
__update = update # private copy of original update() method
class MappingSubclass(Mapping):
def update(self, keys, values):
# provides new signature for update()
# but does not break __init__()
for item in zip(keys, values):
self.items_list.append(item)
tldr
Read the docs on name mangling. | unknown | |
d11706 | train | Generally speaking you can't add something to an existing type. (you can however create a subtype at runtime and add things to that)
In your case though I suggest just using a regular variable that you capture when you create the shim, you can then return that variable as part of your shim and read it later at your descresion
var thelist = new List<Transport>(); //fill out whatever test data you want here, in the case of TransportsGet
using (ShimsContext.Create())
{
var shimLinq = new ShimTable<Transport>()
{
InsertOnSubmitT0 = (transport) =>
{
Transport t = (Transport)transport;
thelist = t.Transports; // assign your outer variable, or do the asserts directly
}
};
}
// do assertions on thelist here
In the comments you mentioned shimming TransportsGet, you can do this the same way and just return thelist in that shim. Then you can do asserts on thelist variable at the end of the test.
However if you want to test a .Where statement, that wont show up on the actual list directly, you have to test it some other way. You could have a thelist with invalid banks and assert that the code doesn't return anything for example | unknown | |

A: Here are the basic rules to use http method,
GET : When you need to fetch or retrive information
POST : When You need to create or insert information
PUT : When you need to update existing record
For more information you can use this link.
https://restfulapi.net/http-methods/
A: Adding to the answer by Lokesh in reference to Laravel.
"index" method uses GET REQUEST as it retrieves records from the database.
"store" method uses POST REQUEST as it stores records in the database.
"update" method uses PUT REQUEST as it updates record in the database.
"show" method uses GET REQUEST as it retrieves single record from the database.
"delete" method uses DELETE REQUEST as it retrieves single record from the database.
Therefore you would want to use POST/PUT REQUEST if you want to change the record in the database. While toggling the status, the standard option is to use PUT, as your are updating a record. | unknown | |
d11710 | train | The setTimeout method of javascript can be used to run code you specify after a set delay in miliseconds.
Try this:
var timeout;
$("#date_1").hover(
function () {
$(this).addClass("door");
timeout = setTimeout(function() { $(this).addClass("doorstatic"); }, 2000);
}, function () {
clearTimeout(timeout);
$(this).removeClass("door doorstatic");
}
);
A: Actually you can just append a call to jQuery's delay to you addClass call.
Something like
$(this).addClass("door").delay(2000).addClass("doorstatic", "slow");
should do the trick.
A: $("#date_1").hover(
function () {
var $this = $(this);
$this.addClass("door");
setTimeout(function() {
$this.addClass("doorstatic");
}, 2000); // 2000 is in mil sec eq to 2 sec.
},
function () {
$(this).removeClass("door doorstatic");
}
);
You can group your classes like removeClass("door doorstatic")
The problem here is that if you mouseover and before two seconds mouse out you will still have the class doorstatic on you element.
The fix:
$("#date_1").hover(
function () {
var $this = $(this),
timer = $this.data("timer") || 0;
clearTimeout(timer);
$this.addClass("door");
timer = setTimeout(function() {
$this.addClass("doorstatic");
}, 2000); // 2000 is in mil sec eq to 2 sec.
$this.data("timer", timer);
},
function () {
var $this = $(this),
timer = $this.data("timer") || 0;
clearTimeout(timer);
$this.removeClass("door doorstatic");
}
);

d11712 | train | Updated to return current year plus previous 5 years. Should be very fast as this is a small recordset.
SELECT YEAR(GETDATE()) as YearNum
UNION
SELECT YEAR(GETDATE()) - 1 as YearNum
UNION
SELECT YEAR(GETDATE()) - 2 as YearNum
UNION
SELECT YEAR(GETDATE()) - 3 as YearNum
UNION
SELECT YEAR(GETDATE()) - 4 as YearNum
UNION
SELECT YEAR(GETDATE()) - 5 as YearNum
ORDER BY YearNum DESC
A: This gets all years from 2004 to the present, using a recursive CTE:
with yearlist as
(
select 2004 as year
union all
select yl.year + 1 as year
from yearlist yl
where yl.year + 1 <= YEAR(GetDate())
)
select year from yearlist order by year desc;
A: Using ROW_NUMBER on any column from any large enough (stable) table would be one way to do it.
SELECT *
FROM (
SELECT TOP 100 2003 + ROW_NUMBER() OVER (ORDER BY <AnyColumn>) AS Yr
FROM dbo.<AnyTable>
) Years
WHERE Yr <= YEAR(GETDATE())
Note that <AnyTable> should contain at least the amount of rows equal to the amount of years you require.
Edit (Cudo's to Joshua)
*
*Preferably, you'd select a table wich you know will not get truncated and/or deleted. A large enough system table should come to mind.
*At present, being a lot older and wiser (older at least), I would implement this requirement using a CTE like mentioned in the answer given by Joshua. The CTE technique is far superior and less error prone than current given ROW_NUMBER solution.
A: DECLARE @YEARS TABLE (Y INT)
DECLARE @I INT, @NY INT
SELECT @I = 2004, @NY = YEAR(GETDATE())
WHILE @I <= @NY BEGIN
INSERT @YEARS SELECT @I
SET @I = @I + 1
END
SELECT Y
FROM @YEARS
ORDER BY Y DESC
A: Try this:
declare @lowyear int
set @lowyear = 2004
declare @thisyear int
set @thisyear = year(getdate())
while @thisyear >= @lowyear
begin
print @thisyear
set @thisyear = (@thisyear - 1)
end
Returns
2009
2008
2007
2006
2005
2004
When you hit Jan 1, 2010. The same code will return:
2010
2009
2008
2007
2006
2005
2004
A: WITH n(n) AS
(
SELECT 0
UNION ALL
SELECT n+1 FROM n WHERE n < 10
)
SELECT year(DATEADD( YY, -n, GetDate()))
FROM n ORDER BY n
A: My two cents:
The CTE is the best answer but I like @Lieven Keersmaekers answer as it doesn’t rely on recursion/loops or creating additional objects such as functions/date-tables. The key variation is mine simply uses the Top clause with an expression, instead of the top 100 (basically the whole table) I ask for N number of unordered rows first. This is quicker, if your base table happens to be quite large.
Tested on SQL Server 2016
DECLARE @startYear smallint;
SET @startYear = 2004;
DECLARE @endYear smallint;
SET @endYear = YEAR(GETDATE());
-- Top uses expression to bring in N number of rows. The (@startYear - 1) is to retain the start year
SELECT [Yr]
FROM (
SELECT TOP (@endYear - (@startYear - 1))
COUNT([object_id]) OVER (ORDER BY [object_id] DESC) + (@startYear - 1) AS [Yr] -- Add initial start year to Count
FROM sys.all_objects
) AS T1
ORDER BY [Yr] DESC
The comments above are valid, but Since OP’s requirements is literally a small set of values from 2004, the sys.all_objects will suffice, as SQL Server install comes with a ton of system objects.
Hope that's a different take.
A: I think you need to create a dates table, then just select your range from it. It can also come in useful when you need to select a date range with X data attached and not have any missed days.
A: SET NOCOUNT ON
DECLARE @max int
set @max = DATEPART(year, getdate())
CREATE TABLE #temp (val int)
while @max >= 2004
BEGIN
insert #temp(val) values(@max)
set @max = @max - 1
END
SELECT * from #temp
A: This is a simple query, check this
(SELECT REPLACE((TO_CHAR(SYSDATE,'YYYY')-Rownum)+1,' ',NULL) yr FROM dual CONNECT BY LEVEL < 32) year
A: Recursive CTE with no variables is a simpler way to go...
WITH Years AS (
SELECT DATEPART(YEAR, GETDATE()) AS Year
UNION ALL
Select Year - 1 FROM Years
WHERE Year > 2004

SELECT Year FROM Years

d11714 | train | I was able to achieve that with IIS successfully! I know the post is old but hopefully, it will save time for solution seekers :)
First (just a reminder) ensure that you have .NET Core Hosting Bundle installed on IIS machine (link could be found here). Bear in mind that it will require at least WinSrvr2012R2 to run.
Now copy published .net core API solution folder to the server. The same for Angular - next reminder here: execute ng build --prod then copy dist folder to the server.
Then configure IIS - create a new web site that points to the Angular app folder. Your Angular app should run at this point (but obviously there is no API yet).
Go to application pools - you will see the pool created for your application. Open basic settings and change CLR version to 'No managed code'.
And finally, click on your Web Site and 'Add application' under it. Point to dotnet core API folder and name it using some short alias. Now you should have a website structure with the application included.
If your angular app URL is:
https://myiissrvr/
your API is under:
https://myiissrvr/[ALIAS]/
DONE
Final remarks:
Usually, web API using URL structure like
https://myiissrvr/api/[controller]/[action]
So after bundling it together, it will look like:
https://myiissrvr/[ALIAS]/api/[controller]/[action]
With that approach, you should be able to attach multiple web API services under statically served Angular website - each one under its own alias. Potentially it might be useful in many scenarios.
A: I've encountered the same problem, then I've found this post on medium, hope this works for you.
Edit:
Actually the solution that I've used is from that article.
The idea is that you can't "publish" the API and the Angular app on the same port, but you can use a proxy to connect from the Angular app to the API on the other port.
Update: sorry for not answering this long time ago.
To deal with the cors issue (in this case) you can use a proxy with the ng serve command.
For example, in my case I have used a proxy.conf.json file like this:
{
"/api/*": {
"target": "http://localhost:3000",
"secure": false,
"pathRewrite": {"^/api" : ""}
}
}
This code rewrite the url on every request to /api/* to the http://localhost:3000 where your api is listening.
So, to illustrate, if in angular you make a request like http://localhost:4200/api/users it will be redirected/rewrited to http://localhost:3000/api/users solving the cors issue.
Now, the way you have to run your angular application is different.
ng serve --proxy-config proxy.conf.json | unknown | |

d11717 | train | According to the HashMultiMap Javadoc, you chose the right MultiMap for that purpose:
The multimap does not store duplicate key-value pairs. Adding a new key-value pair equal to an existing key-value pair has no effect.
Now, you only have to make sure that equals() (and hashCode()) is implemented correctly on your values. I don't think you should worry about a faster way to do this. The HashMultiMap should be implemented pretty efficiently.
A: If you want this behavior why not use a structure like:
Map<Key,Set<Values>> myMap = new HashMap<Key,Set<Values>>();
EDIT:
If you want to use the HashMultiMap i would recommend the one bellow
Implementation of the MultiMap interface that uses a HashMap for the

A: Apple expects you to use enumerateAttributesInRange:options:usingBlock:. The block you supply will receive ranges and the attributes applicable for that range.
I've used that in my code to create invisible buttons that are placed behind text so that it acts as a hyperlink.
You could also use enumerateAttribute:inRange:options:usingBlock: if there's only one you're interested in, but no halfway house is provided where you might be interested in, say, two attributes but not every attribute.
A: Apple's Docs have a number of methods to access attributes:
To retrieve attribute values from either type of attributed string, use any of these methods:
attributesAtIndex:effectiveRange:
attributesAtIndex:longestEffectiveRange:inRange:
attribute:atIndex:effectiveRange:
attribute:atIndex:longestEffectiveRange:inRange:
fontAttributesInRange:
rulerAttributesInRange:
A: If you need all of the attributes from the string in the entire range, use this code:
NSDictionary *attributesFromString = [stringWithAttributes attributesAtIndex:0 longestEffectiveRange:nil inRange:NSMakeRange(0, stringWithAttributes.length)];
A: Swift 5 – 4
let attributedText = NSAttributedString(string: "Hello, playground", attributes: [
.foregroundColor: UIColor.red,
.backgroundColor: UIColor.green,
.ligature: 1,
.strikethroughStyle: 1
])
// retrieve attributes
let attributes = attributedText.attributes(at: 0, effectiveRange: nil)
// iterate each attribute
for attr in attributes {
print(attr.key, attr.value)

d11725 | train | Isn't Firebase stores all its data in MongoDB?
Update May 2016
Apparently a page where Firebase was mentioned in MongoDB's site was removed (http://www.mongodb.org/about/production-deployments/)
After some search on their site I've found another page in their blog
https://www.mongodb.com/post/45270275688/mongodbs-growing-ecosystem (mirror)
where they say:
it’s great to see so many companies building on MongoDB. Here are just a few:
*
*Modulus. A Node.js platform as a service (PaaS) offering, Modulus includes MongoDB as its default data store. This follows related offerings from Meteor and Firebase.
An alternative to MongoDB would be RethinkDB and recently the team behind RethinkDB released Horizon, an open-source backend platform on NodeJS and that is kind of a locally hosted Firebase. Here's a nice talk about Horizon.
A: Given that both MongoDB and Firebase are non-relational in nature, most of your data should map to Firebase cleanly. The Firebase REST endpoints support regular JSON, so getting your data in (and, back out if you choose) should also be easy. The main areas you need to keep watch for are:
*
*The Firebase API is realtime/asynchronous in nature; specifically, when clients are reading data. Migrating your backend request/response code to the client and using this approach will probably be the biggest area with regard to level of effort.
*There will also be a disparity in the feature set that MongoDB and Firebase provide; notable areas include Mongo's support for doing things like MapReduce, Cursors, and free-text queries (Firebase doesn't currently support these areas).
The other thing to keep in mind is that Firebase isn't an all-or-nothing type of undertaking. Apps can definitely take advantage of the realtime, scaling, and platform features piecemeal.
A: Not specifically answering the question, but if you find Firebase lacking a few features which you you are used to with Mongo -
I found a node package which will allow you to run both with Firebase as the master DB.

A: Here's a version that might be a little easier to follow:
import math, random
# generate array of random values
a = np.random.rand(4500)
# make a utility list of every position in that array, and shuffle it
indices = [i for i in range(0, len(a))]
random.shuffle(indices)
# set the proportion you want to keep the same
proportion = 0.5
# make two lists of indices, the ones that stay the same and the ones that get shuffled
anchors = indices[0:math.floor(len(a)*proportion)]
not_anchors = indices[math.floor(len(a)*proportion):]
# get values of non-anchor indices, and shuffle them
not_anchor_values = [a[i] for i in not_anchors]
random.shuffle(not_anchor_values)
# loop original array, if an anchor position, keep original value
# if not an anchor, draw value from shuffle non-anchor value list and increment the count
final_list = []
count = 0
for e,i in enumerate(a):

# test proportion of matches and non-matches in output
match = []

for e,i in enumerate(a):
if i == final_list[e]:
match.append(True)
else:
not_match.append(True)
len(match)/(len(match)+len(not_match))
Comments in the code explain the approach.
A: (EDITED to include a different and more accurate approach)
One should note that not all values of the shuffled fraction p (number of shuffled elements divided by the total number of elements) is accessible.
The possible value of p depend on the size of the input and on the number of repeated elements.
That said, I can suggest two possible approaches:
*
*split your input into pinned and unpinned indices of the correct size and then shuffle the unpinned indices.
import numpy as np
def partial_shuffle(arr, p=1.0):
n = arr.size
k = round(n * p)
shuffling = np.arange(n)
shuffled = np.random.choice(n, k, replace=False)
shuffling[shuffled] = np.sort(shuffled)
return arr[shuffling]
The main advantage of approach (1) is that it can be easily implemented in a vectorized form using np.random.choice() and advanced indexing.
On the other hand, this works well as long as you are willing to accept that some shuffling may return you some elements unshuffled because of repeating values or simply because the shuffling indexes are accidentally coinciding with the unshuffled ones.
This causes the requested value of p to be typically larger than the actual value observed.
If one needs a relatively more accurate value of p, one could just try performing a search on the p parameter giving the desired value on the output, or go by trial-and-error.
*implement a variation of the Fisher-Yates shuffle where you: (a) reject swappings of positions whose value is identical and (b) pick only random positions to swap that were not already visited.
def partial_shuffle_eff(arr, p=1.0, inplace=False, tries=2.0):
if not inplace:
arr = arr.copy()
n = arr.size
k = round(n * p)
tries = round(n * tries)
seen = set()
i = l = t = 0
while i < n and l < k:
seen.add(i)
j = np.random.randint(i, n)
while j in seen and t < tries:
j = np.random.randint(i, n)
t += 1
if arr[i] != arr[j]:
arr[i], arr[j] = arr[j], arr[i]
l += 2
seen.add(j)
while i in seen:
i += 1
return arr
While this approach gets to a more accurate value of p, it is still limited by the fact that the target number of swaps must be even.
Also, for inputs with lots of uniques the second while (while j in seen ...) is potentially an infinite loop so a cap on the number of tries should be set.
Finally, you would need to go with explicit looping, resulting in a much slower execution speed, unless you can use Numba's JIT compilation, which would speed up your execution significantly.
import numba as nb
partial_shuffle_eff_nb = nb.njit(partial_shuffle_eff)
partial_shuffle_eff_nb.__name__ = 'partial_shuffle_eff_nb'
To test the accuracy of the partial shuffling we may use the (percent) Hamming distance:
def hamming_distance(a, b):
assert(a.shape == b.shape)
return np.count_nonzero(a == b)
def percent_hamming_distance(a, b):
return hamming_distance(a, b) / len(a)
def shuffling_fraction(a, b):
return 1 - percent_hamming_distance(a, b)
And we may observe a behavior similar to this:
funcs = (
partial_shuffle,
partial_shuffle_eff,
partial_shuffle_eff_nb
)
n = 12
m = 3
arrs = (
np.zeros(n, dtype=int),

You can use the item slot of the data table. Some vuetify components comes with special sections for easier customization called slots, in this case the item slot of the data table let you customize individual colums content like this:
<v-data-table
:headers="headers"
:items="desserts"
:items-per-page="5"
class="elevation-1"
>
<template #item.calories="{ item }">
<v-chip dark color="red darken-2">{{ item.calories }}</v-chip>
</template>
<template #item.fat="{ item }">
<v-chip dark color="orange darken-2">{{ item.fat }}</v-chip>
</template>
</v-data-table>
If you're using es-lint you might encounter a warning mention something about the valid-v-slot rule, this is a known false positive that you can read more about in this GitHub issue thread, I personally just turn that es-lint rule off.
For more info about data table slots, check the vuetify documentation page. | unknown | |

if (v.length < 3 || v == $(this).data('prev-val')) return;

d11733 | train | by default, a string field will have a standard tokenizer, that will emit a single token "FRUIT12" for the "FRUIT12" input.
You need to use a word_delimiter token filter in your field analyzer to allow the behavior your are expecting :
GET _analyze
{
"text": "FRUIT12",
"tokenizer": "standard"
}
gives
{
"tokens": [
{
"token": "FRUIT12",
"start_offset": 0,
"end_offset": 7,
"type": "<ALPHANUM>",
"position": 0
}

}
----------- and
GET _analyze
{
"text": "FRUIT12",
"tokenizer": "standard",
"filters": ["word_delimiter"]
}
gives
{
"tokens": [
{
"token": "FRUIT",
"start_offset": 0,
"end_offset": 5,
"type": "<ALPHANUM>",

},
{
"token": "12",
"start_offset": 5,
"end_offset": 7,
"type": "<ALPHANUM>",
"position": 1
}
]
}
If your add the word_delimiter token filter on your field, any search query on this field will also have the word_delimiter token filter enabled ( unless you override it with search_analyzer option in the mapping )
so "FRUIT12" mono-term query will be "translated" to ["FRUIT", "12"] multi term query. | unknown | |

d11737 | train | You are incorrectly handling the files and everything else when inserting them into the database. All files that are already there are damaged and probably destroyed.
addslashes() is no escaping function for a database. Always use the escaping function that comes with the DB extension you are using. If you are using mysqli, then the correct function must be mysqli_real_escape_string().
You should however have a look at prepared statements. These will use an different way of transferring the data that does not need escaping. Do pay attention however to the setting of magic quotes. The preferred setting is OFF, and the recent PHP versions starting with 5.4 have this feature removed already. So you have to deal with escaping the data you insert into the database anyway. | unknown | |

d11743 | train | If all first names had the same length, then you would be able to use sortrows, but in your case, that would require padding and modifying your array, anyway, so that you're better off converting it into "LAST FIRST MIDDLE" before applying sort. Fortunately, there's a simple regular expression for that:
names = {'John Doe';'Roger Adrian';'John Fitzgerald Kennedy'};
names_rearranged = regexprep(names,'(.*) (\w*)$','$2 $1')
names_rearranged =
'Doe John'
'Adrian Roger'
'Kennedy John Fitzgerald'

d11744 | train | Probably the best route is do a custom lookup and change the extended data type of the key field to reflect that. In this way the change is reflected in all places. See form FiscalCalendarYearLookup and EDT FiscalYearName as an example of that.
If you only need to change a single place, the easy option is to override performFormLookup on the calling form. You should also override the DisplayLength property of the extended data type of the long field.
public void performFormLookup(FormRun _form, FormStringControl _formControl)
{
FormGridControl grid = _form.control(_form.controlId('grid'));
grid.autoSizeColumns(false);
super(_form,_formControl);
}
This will not help you unless you have a form, which may not be the case in this report scenario.
Starting in AX 2009 the kernel by default auto-updates the control sizes based on actual record content. This was a cause of much frustration as the sizes was small when there was no records and these sizes were saved! Also the performance of the auto-update was initially bad in some situations. As an afterthought the grid control autoSizeColumns method was provided but it was unfortunately never exposed as a property.
A: you can extends the sysTableLookup class and override the buildFromGridDesign method to set the grid control width.
protected void buildFormGridDesign(FormBuildGridControl _formBuildGridControl)
{
if (gridWidth > 0)
{
_formBuildGridControl.allowEdit(true);
_formBuildGridControl.showRowLabels(false);
_formBuildGridControl.widthMode(2);
_formBuildGridControl.width(gridWidth);

d11749 | train | Drawing the 'hash mark' is going to be the real problem. TreeView has a DrawMode property but its DrawItem event doesn't let you draw between the nodes.
You need to handle this by changing the cursor to indicate what is going to happen. Use the GiveFeedback event, set e.UseCustomCursors to false and assign Cursor.Current to a custom cursor that indicates the operation.
A: This article articulates the same issue and provides an approach somewhat similar to the one you are already following (with the exception that the thresholds are essentially percentages of the height of the tree node). Based on this, and the fact that when I was doing this before, that was the best approach I could find, I think you're basically on track. | unknown | |

d11755 | train | With the introduction of (i|android|windows)phones, things have changed, and to get a correct and complete solution that works on any device is really time-consuming.
You can have a peek at https://realfavicongenerator.net/favicon_compatibility or http://caniuse.com/#search=favicon to get an idea on the best way to get something that works on any device.
You should have a look at

to automate a large part of this work, and probably at https://github.com/audreyr/favicon-cheat-sheet to understand how it works (even if this latter resource hasn't been updated in a loooong time).

A: Below given some information about fav Icon
What Is FavIcon?
FavIcon is nothing but small image which appears top left along with the application address bar title.Standard size specification for favicon.ico is 16 by 16 pixel. Please see below attached figure.
How It Works ?
Usually we add our FavIcon.ico image in the route solution folder and automatically application picks it while running. But most of the time we might have to use below both link reference.
<link rel="icon" href="favicon.ico" type="image/ico"/>
<link rel="shortcut icon" href="favicon.ico" type="image/x-icon"/>
Some browser expect one (rel="icon") Some other browser expect other rel="shortcut icon"
Type=”image/x-icon” OR Type=”image/ico”: once expect exact ico image and one expect any image even formatted from .jpg or .pn ..etc.
We have to use above two tags to the common pages like – Master page , Main frame which is getting used in all the pages
A: you could take a look at the w3 how to, i think you will find it helpful
your link tag attribute should be rel="icon"
A: I use this on my site and it works great.
<link rel="shortcut icon" type="image/x-icon" href="images/favicon.ico"/>
A: There is a very simple method to set a favicon, which had been around for a long time AFAIK.
Place the favicon.ico file in the default location.
i.e
http://www.yoursite.com/favicon.ico
This works in almost every browser without a <link> tag.
However, this works only if it is an *.ico file. PNGs and other formats still have to be linked with a <link> tag
A: <!DOCTYPE html
PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html lang="en-US">
<head profile="http://www.w3.org/2005/10/profile">
<link rel="icon"
type="image/png"
href="http://example.com/myicon.png">
</head>
<body>
...
</body>
</html>
rel="shortcut icon" should be rel="icon"
Source: W3C
A: From experience of my favicon.ico not appearing, I am sharing my experience. You can't get it to show until you put your website on a host, therefore, try put it on a localhost using XAMPP - http://www.apachefriends.org/en/xampp.html. This is how the favicon appears and like others recommended, change:
rel="shortcut icon"
to
rel="icon"
Also this way .png favicons can be used for slickness.
A: <head>
<link rel="shortcut icon" href="favicon.ico">
</head>
A: In my site, I use this:
<!-- for FF, Chrome, Opera -->
<link rel="icon" type="image/png" href="/assets/favicons/favicon-16x16.png" sizes="16x16">
<link rel="icon" type="image/png" href="/assets/favicons/favicon-32x32.png" sizes="32x32">
<!-- for IE -->
<link rel="icon" type="image/x-icon" href="/assets/favicons/favicon.ico" >
<link rel="shortcut icon" type="image/x-icon" href="/assets/favicons/favicon.ico"/>
To simplify your life, use this favicons generator http://realfavicongenerator.net
A: This method is recommended
<link rel="icon"
type="image/png"
href="/somewhere/myicon.png" />
A: Try put this in the head of the document:
<link rel="shortcut icon" type="image/x-icon" href="/favicon.ico"/>
A: I use this https://realfavicongenerator.net/ to generate all the possible favicons scenarios and it is free. | unknown | |

d11759 | train | Despite the fact that using a VARCHAR(255) as a foreign key is probably highly inefficient and/or will require huge indices, I guess that generally an option that defines the foreign key of the other table would come in handy here, similar to targetForeignKey for belongsToMany associations. You may to want to suggest that as an enhancement.
Result formatters
Currently this doesn't seem to be possible out of the box using associations, so you'd probably have to select and inject the associated records yourself, for example in a result formatter.
$Villas
->find()
->formatResults(function($results) {
/* @var $results \Cake\Datasource\ResultSetInterface|\Cake\Collection\Collection */
// extract the custom foreign keys from the results
$keys = array_unique($results->extract('complex')->toArray());
// find the associated rows using the extracted foreign keys
$villas = \Cake\ORM\TableRegistry::get('Villas')
->find()
->where(['complex IN' => $keys])
->all();
// inject the associated records into the results
return $results->map(function ($row) use ($villas) {
if (isset($row['complex'])) {
// filters the associated records based on the custom foreign keys
// and adds them to a property on the row/entity
$row['complexs'] = $villas->filter(function ($value, $key) use ($row) {
return
$value['complex'] === $row['complex'] &&
$value['id'] !== $row['id'];
})
->toArray(false);
}
return $row;
});
});
This would fetch the associated rows afterwards using the custom foreign keys, and inject the results, so that you'd end up with the associated records on the entities.
See also Cookbook > Database Access & ORM > Query Builder > Adding Calculated Fields
There might be other options, like for example using a custom eager loader that collects the necessary keys, combined with a custom association class that uses the proper key for stitching the results together, see

d11762 | train | This is indeed possible, as I have just done it. You need to trap the 'moveend' and 'move' events from the map being panned or zoomed (moveend is triggered at the end of a zoom, but you could trap 'zoomend' as well to be on the safe side). If you trap these using the parent map as the context then you can get the new map centre. Bear in mind that the map centre can change when the map is zoomed if the navigation control is being used and the zoom is done using the mouse. Then use the moveTo method (childmap.moveTo().
I've chosen the moveTo method as (although not well documented) this is what is always finally called in any pan or zoom event on any map. As an aside, calling moveTo will also cause the 'move', 'moveend' events to be triggered on the child map.
If you make a collection of maps using json, and use jQuery, the actual code would look something like this (I'm assuming you know how to trap map events in OpenLayers);
var newCentre = zoomedMap.getCenter();
$.each(maps, function (ind, map) {
if (map !== zoomedMap) map.moveTo(newCentre, newZoom);
});
where maps is my collection of maps, zoomedMap is the map the user actually triggered the pan or zoom event on (I've called it zoomeMap but it could just as easily be called pannedMap), and (obviously) map is the map in the collection that needs moving.
I played around a bit before I settled for the above code. The advantage here is that $.each doesn't wait for the moveTo function to return, so you get a much slicker looking synch. Of course this wouldn't really be an issue if you're only synching two maps.
I'm sorry to have posted this so long after the question was asked, but maybe it will help any new searchers out there. | unknown | |
d11763 | train | Libraries like commons-beanutils can help you if you want to compare bean properties (values returned by getters) instead of comparing field values.
However, if you want to stick with plain reflection, you should:
*
*Use Class.getDeclaredFields() instead of Class.getFields(), as the latter only returns the public fields.
*Since fields only depend on their class, you should cache the result and keep the fields in a static / instance variable rather than invoking getDeclaredFields() for each comparison.
*Once you have an object of that class (say o), in order to get the value of some field f for that particular object, you need to call: f.get(o).
A: You might check out org.apache.commons.lang.builder.EqualsBuilder which will save you a lot of this hassle if you're wanting to do a field by field comparison.
org.apache.commons.lang.builder.EqualsBuilder.reflectionEquals(Object, Object)
If you're wanting to compare fields yourself, check out java.lang.Class.getDeclaredFields() which will give you all the fields including non-public fields.
To compare the value of the fields use f.get(qa).equals(f.get(qa4)) Currently, you are actually comparing the field instances and not the values.
A: // If you want to have some fields, not all field then use this.
public boolean compareObject(Object object) throws NoSuchFieldException, SecurityException, IllegalArgumentException, IllegalAccessException

Now to add a class for a field "name" of form1 do :
{{ form1.name|add_class:"baz" }}
or add 2 and more
{{ form1.name|add_class:"baz baz2 baz3" }}
which will add class ="baz baz2 baz3" to your field html output
You can also add attributes :
{{ form1.name|attr:"size:200"|attr:"color:blue"}}
and combine the two ^^
{{ form1.name|add_class:"baz baz2 baz3"|attr:"size:200"|attr:"color:blue"}}

This item is rendered in the menu, unless hideNoSelectionOption is set to true in your menu component. In that case, the option is selected when the user interacts with the menu.
Just bear in mind that if an entry is required and this "no selection" option is the one selected, there will be a validation error.
An alternative that requires a little more of coding is to use a f:selectItem with value="#{null}", to represent the case in which an user did not select a value.

d11774 | train | Not really an answer to your question as you are using MD5. However as this thread pops up when searching for the error, I am attaching this to it.
Similar errors happen when bcrypt is used to generate passwords for auth_basic:
htpasswd -B <file> <user> <pass>
Since bcrypt is not supported within auth_basic ATM, mysterious 500 errors can be found in nginx error.log, (usually found at /var/log/nginx/error.log), they look something like this:
*1 crypt_r() failed (22: Invalid argument), ...
At present the solution is to generate a new password using md5, which is the default anyway.
Edited to address md5 issues as brought up by @EricWolf in the comments:
md5 has its problems for sure, some context can be found in the following threads
*
*Is md5 considered insecure?
*Is md5 still considered secure for single use authentications?
Of the two, speed issue can be mitigated by using fail2ban, by banning on failed basic auth you'll make online brute forcing impractical (guide). You can also use long passwords to try and fortify a bit as suggested here.
Other than that it seems this is as good as it gets with nginx...
A: I was running Nginx in a Docker environment and I had the same issue. The reason was that some of the passwords were generated using bcrypt. I resolved it by using nginx:alpine.
A: Do you want a MORE secure password hash with nginx basic_auth? Do this:
echo "username:"$(mkpasswd -m sha-512) >> .htpasswd
SHA-512 is not considered nearly as good as bcrypt, but it's the best nginx supports at the moment.
A: I will just stick the htpassword file under "/etc/nginx" myself.
Assuming it is named htcontrol, then ...
sudo htpasswd -c /etc/nginx/htcontrol calvin
Follow the prompt for the password and the file will be in the correct place.
location / {
...
auth_basic "Restricted";
auth_basic_user_file htcontrol;
}
or auth_basic_user_file /etc/nginx/htcontrol; but the first variant works for me
A: I had goofed up when initially creating a user. As a result, the htpasswd file looked like:
user:
user:$apr1$passwdhashpasswdhashpasswdhash...
After deleting the blank user, everything worked fine.
A: I just had the same problem - after checking log as suggested by @Drazen Urch I've discovered that the file had root:root permissions - after changing to forge:forge (I'm using Forge with Digital Ocean) - the problem went away.
A: Well, just use correct RFC 2307 syntax:
passwordvalue = schemeprefix encryptedpassword
schemeprefix = "{" scheme "}"
scheme = "crypt" / "md5" / "sha" / altscheme
altscheme = "x-" keystring
encryptedpassword = encrypted password
For example: sha1 for helloworld for admin will be
*
*admin:{SHA}at+xg6SiyUovktq1redipHiJpaE=
I had same error cause i wrote {SHA1} what against RFC syntax. When i fixed it - all worked like a charm. {sha} will not work too. Only correct {SHA}.
A: First, check out your nginx error logs:
tail -f /var/log/nginx/error.log
In my case, I found the error:
[crit] 18901#18901: *6847 open() "/root/temp/.htpasswd" failed (13: Permission denied),
The /root/temp directory is one of my test directories, and cannot be read by nginx. After change it to /etc/apache2/ (follow the official guide https://docs.nginx.com/nginx/admin-guide/security-controls/configuring-http-basic-authentication/) everything works fine.
===
After executing the ps command we can see the nginx worker process maintained by the user www-data, I had tried to chown www-data:www-data /root/temp to make sure www-data can access this file, but it still not working. To be honest, I don't have a very deep understanding on Linux File Permissions, so I change it to /etc/apache2/ to fix this in the end. And after a test, you can put the .htpasswd file in other directories which in /etc (like /etc/nginx).
A: I too was facing the same problem while setting up authentication for kibana. Here is the error in my /var/log/nginx/error.log file
2020/04/13 13:43:08 [crit] 49662#49662: *152 crypt_r() failed (22:
Invalid argument), client: 157.42.72.240, server: 168.61.168.150,
request: “GET / HTTP/1.1”, host: “168.61.168.150”
I resolved this issue by adding authentication using this.
sudo sh -c "echo -n 'kibanaadmin:' >> /etc/nginx/htpasswd.users"
sudo sh -c "openssl passwd -apr1 >> /etc/nginx/htpasswd.users"
You can refer this post if you are trying to setup kibana and got this issue.

A: In my case, I was using plain text password by -p flag, and coincidentally my password start with $ character.
So I updated my password and thus the error was gone.
NB: Other people answer helped me a lot to figure out my problem. I am posting my solution here if anyone stuck in a rare case like me.
A: In my case, I had my auth_basic setup protecting an nginx location that was served by a proxy_pass configuration.
The configured proxy_pass location wasn't returning a successful HTTP200 response, which caused nginx to respond with an Internal Server Error after I had entered the correct username and password.
If you have a similar setup, ensure that the proxy_pass location protected by auth_basic is returning an HTTP200 response after you rule out username/password issues. | unknown | |

By this your app will never crashed as it is pure conditional for your needed objects with checking of types. If your "data" key is array then only it will proceed for your array. Thanks.
A: The crash happens because you assume that the object you receive is NSMutableArray, even though the object has been created outside your code.
In this case, an array that your code gets is an instance of an array optimized for handling a single element; that is why the cast is unsuccessful.
When this happens, you can make a mutable copy of the object:
array = (dictionnary["data"]! as! NSArray).mutableCopy() as! NSMutableArray

array = (responseObject as! NSArray).mutableCopy() as! NSMutableArray | unknown | |

d11786 | train | In order for that data to be posted to the server, you have to store it in a form value.
HTML elements in their entirety aren't posted to the server. Only the key/value pairs of form elements are. (WebForms is trying to trick you into thinking that the whole page is posted to the server, but it's a lie.)
Add a hidden form field to the page, something as simple as this:
<asp:Hidden id="someHiddenField" />
Then in the JavaScript, set the value of that field:
document.getElementById('<%= someHiddenField.ClientID %>').value = 'true';
Then when the page posts back to the server, the 'true' value will be in that hidden field:
someHiddenField.Value
A: asp:Hidden doesn't exist. only form elements can actually postback data. The server side will take the postback data and load it into the form element provided that the runat=server is set.
in markup or html:
<input type="hidden" runat="server" ID="txtHiddenDestControl" />
javascript:
document.getElementById('<%= txtHiddenDestControl.ClientID %>').value = '1';

Setting up the VS2015 solution generally goes as follows:
*
*Create new folder project
*Put game source in project/src
*Create shared items project in project/
*Create an android makefile project into project/android
*Create an android basic application(ANT) project into project/android
*Copy the contents of SDL2/android-proj to project/android
*In the solution explorer check "show all files" and "include in project" all files from SDL2/android-proj except jni to the basic application project.
*In the references of the basic app project add the makefile project.
*In the references of the makefile project add the shared items project.
*Edit project/android/jni/src/Android.mk to compile your files in projects/src
*After building the makefile project, add its resulting .so files from project/android/libs/ to the basic app project.
*Create other project like usual except instead of including source, just include shared items project in references.

d11791 | train | Add this to your css:
input[type=submit]{
height: 22px;
line-height: 18px;
cursor: pointer;
}
A: Instead of using height and width like you are currently doing you should use padding because then the text is vertically centred.
The reason that the is not being sent is because you are not currently using a form so you need to add a form tag around the stuff that you want in the form so you could use this:
<form action='#' method='get'>
<input class="menu_button" type="submit" value="Log in" />
</form>
Here is a working fiddle:
http://jsfiddle.net/Hive7/26tyd/3/
A: You just need to add below code in your code:
box-sizing: border-box;
-moz-box-sizing: border-box;
And to adjust the hight and with I would sugegst you to play with "min-width" and "padding". As giving "Width" and "Height" can limit your button and if you have more test or padding the height and width will not let the background increase.
Please see the updated code:-
.menu_button {
-moz-box-shadow:inset 0px -1px 0px 0px #000000;
-webkit-box-shadow:inset 0px -1px 0px 0px #000000;
box-shadow:inset 0px -1px 0px 0px #000000;

border-bottom-right-radius:0px;

-moz-border-radius-bottomleft:0px;
border-bottom-left-radius:0px;
text-indent:0;
border:1px solid #fa1e0f;

text-decoration:none;
text-align:center;
text-shadow:1px 1px 0px #33302f;
box-sizing: border-box; /*ADDED*/
-moz-box-sizing: border-box; /*ADDED*/
padding:5px;
}
Hope this helps!
A: Try
margin: 0;
padding: 0;
white-space: normal;
box-sizing: content-box;
The input tags are styled different by the user agent stylesheet than a tags.
A: As I understand you need to style both elements the same?

d11798 | train | The companion object of a case class extends FunctionX[T1, T2, <CaseClass>] so that you can use it to construct instances of the case class.
So, for example, if you have a case class
case class Foo(i: Int, s: String)
the compiler will generate a companion object
object Foo extends (Int, String) ⇒ Foo with Product2[Int, String] {
def apply(i: Int, s: String) = new Foo(i, s)
// and some other stuff such as equals, hashCode, copy
}
This allows you to construct an instance of Foo like this:
Foo(42, "Hello")
instead of
new Foo(42, "Hello")
So, to conclude: the reason, why you can pass the Dept companion object as a function is because it is a function.
A: Dept is not a "case class type", it's the companion object for the case class. It extends Function1 (and has .apply method, that's part of the interface), so you can use it wherever a function is expected.
The second snipped fails because { x => Dept(x) } is it's own anonymous function, not Dept object.
A: It has a lot of sense, because if you just give as paramenter Dept it will behave ass a function that takes a String as parameter, and return an instance of the class Dept, meaning a Dept object (It is like give the new or apply function as parameter), look that the following code is valid also:
val c: Dept.type = Dept
val dep = c("Name1")
dep
res1: Dept = Dept(Name1)
dep.evaluate

d11800 | train | Set AutoPostBack=true on btnAnswer. It's not triggering the server to act on the button click.
A: If you want to get event btnAnswer_Click triggered , then you must render the same Content and assign the eventHandler in every pageload(ie; the page load after the client button click must render the button again and EventHandler must be assigned).
Asp.net won't trigger the event if it doesn't find the controls in the pageload. Remember, after clicking a button, the page load event triggers first and then only the Click_event will be triggered.
The RenderQuestions() must be called in the btnAnswer_Click Event too. This will avoid the a step back problem.
In this scenario I would recommend you to learn about ajax (using jQuery library) requests in asp.net (using WebMethods or webservices) to avoid these postbacks. | unknown |
