To revert all the migrations which are applied to DB simply run:
update-database 0
It should be followed with running Remove-Migration
as many times as there are migration files visible in the Migration directory. The command deletes the latest migration and also updates the snapshot.
From the man git-stash
page:
The modifications stashed away by this command can be listed with git stash list, inspected with git stash show
show [<stash>]
Show the changes recorded in the stash as a diff between the stashed state and
its original parent. When no <stash> is given, shows the latest one. By default,
the command shows the diffstat, but it will accept any format known to git diff
(e.g., git stash show -p stash@{1} to view the second most recent stash in patch
form).
To list the stashed modifications
git stash list
To show files changed in the last stash
git stash show
So, to view the content of the most recent stash, run
git stash show -p
To view the content of an arbitrary stash, run something like
git stash show -p stash@{1}
By reading online (tables tutorial) it seems tables behave like arrays so you're looking for:
Way1
names = {'John', 'Joe', 'Steve'}
for i = 1,3 do print( names[i] ) end
Way2
names = {'John', 'Joe', 'Steve'}
for k,v in pairs(names) do print(v) end
Way1 uses the table index/key
, on your table names
each element has a key starting from 1, for example:
names = {'John', 'Joe', 'Steve'}
print( names[1] ) -- prints John
So you just make i
go from 1 to 3.
On Way2 instead you specify what table you want to run and assign a variable for its key and value for example:
names = {'John', 'Joe', myKey="myValue" }
for k,v in pairs(names) do print(k,v) end
prints the following:
1 John
2 Joe
myKey myValue
I did it in my project ,
make a div with back ground url as gif , which is nothing but animation gif
<div class="busyindicatorClass"> </div>
.busyindicatorClass
{
background-url///give animation here
}
in your ajax call , add this class to the div and in ajax success remove the class.
it will do the trick thatsit.
let me know if you need antthing else , i can give you more details
in the ajax success remove the class
success: function(data) {
remove class using jquery
}
One important thing for passing multidimensional arrays is:
First array dimension
need not be specified.Second(any any further)dimension
must be specified.1.When only second dimension is available globally (either as a macro or as a global constant)
const int N = 3;
void print(int arr[][N], int m)
{
int i, j;
for (i = 0; i < m; i++)
for (j = 0; j < N; j++)
printf("%d ", arr[i][j]);
}
int main()
{
int arr[][3] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
print(arr, 3);
return 0;
}
2.Using a single pointer: In this method,we must typecast the 2D array when passing to function.
void print(int *arr, int m, int n)
{
int i, j;
for (i = 0; i < m; i++)
for (j = 0; j < n; j++)
printf("%d ", *((arr+i*n) + j));
}
int main()
{
int arr[][3] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
int m = 3, n = 3;
// We can also use "print(&arr[0][0], m, n);"
print((int *)arr, m, n);
return 0;
}
Please check the below code. Automatically it will convert as DataTable
private void ConvertDataReaderToTableManually()
{
SqlConnection conn = null;
try
{
string connString = ConfigurationManager.ConnectionStrings["NorthwindConn"].ConnectionString;
conn = new SqlConnection(connString);
string query = "SELECT * FROM Customers";
SqlCommand cmd = new SqlCommand(query, conn);
conn.Open();
SqlDataReader dr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
DataTable dtSchema = dr.GetSchemaTable();
DataTable dt = new DataTable();
// You can also use an ArrayList instead of List<>
List<DataColumn> listCols = new List<DataColumn>();
if (dtSchema != null)
{
foreach (DataRow drow in dtSchema.Rows)
{
string columnName = System.Convert.ToString(drow["ColumnName"]);
DataColumn column = new DataColumn(columnName, (Type)(drow["DataType"]));
column.Unique = (bool)drow["IsUnique"];
column.AllowDBNull = (bool)drow["AllowDBNull"];
column.AutoIncrement = (bool)drow["IsAutoIncrement"];
listCols.Add(column);
dt.Columns.Add(column);
}
}
// Read rows from DataReader and populate the DataTable
while (dr.Read())
{
DataRow dataRow = dt.NewRow();
for (int i = 0; i < listCols.Count; i++)
{
dataRow[((DataColumn)listCols[i])] = dr[i];
}
dt.Rows.Add(dataRow);
}
GridView2.DataSource = dt;
GridView2.DataBind();
}
catch (SqlException ex)
{
// handle error
}
catch (Exception ex)
{
// handle error
}
finally
{
conn.Close();
}
}
Just regex out null bytes:
s/\x00//g;
Just add an onclick
event to the button
:
<button onclick="location.href = 'www.yoursite.com';" id="myButton" class="float-left submit-button" >Home</button>
But you shouldn't really have it inline like that, instead, put it in a JS block and give the button
an ID:
<button id="myButton" class="float-left submit-button" >Home</button>
<script type="text/javascript">
document.getElementById("myButton").onclick = function () {
location.href = "www.yoursite.com";
};
</script>

You're checking the wrong method. Moq requires that you Setup (and then optionally Verify) the method in the dependency class.
You should be doing something more like this:
class MyClassTest
{
[TestMethod]
public void MyMethodTest()
{
string action = "test";
Mock<SomeClass> mockSomeClass = new Mock<SomeClass>();
mockSomeClass.Setup(mock => mock.DoSomething());
MyClass myClass = new MyClass(mockSomeClass.Object);
myClass.MyMethod(action);
// Explicitly verify each expectation...
mockSomeClass.Verify(mock => mock.DoSomething(), Times.Once());
// ...or verify everything.
// mockSomeClass.VerifyAll();
}
}
In other words, you are verifying that calling MyClass#MyMethod
, your class will definitely call SomeClass#DoSomething
once in that process. Note that you don't need the Times
argument; I was just demonstrating its value.
I don't understand where the first "result with sample data" is coming from, but the problem in the console app is that you're using SelectMany
to look at each item in each group.
I think you just want:
List<ResultLine> result = Lines
.GroupBy(l => l.ProductCode)
.Select(cl => new ResultLine
{
ProductName = cl.First().Name,
Quantity = cl.Count().ToString(),
Price = cl.Sum(c => c.Price).ToString(),
}).ToList();
The use of First()
here to get the product name assumes that every product with the same product code has the same product name. As noted in comments, you could group by product name as well as product code, which will give the same results if the name is always the same for any given code, but apparently generates better SQL in EF.
I'd also suggest that you should change the Quantity
and Price
properties to be int
and decimal
types respectively - why use a string property for data which is clearly not textual?
You can use FileInfo object to get all information of your file.
FileInfo f = new FileInfo(@"C:\Hello\AnotherFolder\The File Name.PDF");
MessageBox.Show(f.Name);
MessageBox.Show(f.FullName);
MessageBox.Show(f.Extension );
MessageBox.Show(f.DirectoryName);
To pass multiple headers in a curl request you simply add additional -H
or --header
to your curl command.
Example
//Simplified
$ curl -v -H 'header1:val' -H 'header2:val' URL
//Explanatory
$ curl -v -H 'Connection: keep-alive' -H 'Content-Type: application/json' https://www.example.com
Going Further
For standard HTTP header fields such as User-Agent, Cookie, Host, there is actually another way to setting them. The curl command offers designated options for setting these header fields:
For example, the following two commands are equivalent. Both of them change "User-Agent" string in the HTTP header.
$ curl -v -H "Content-Type: application/json" -H "User-Agent: UserAgentString" https://www.example.com
$ curl -v -H "Content-Type: application/json" -A "UserAgentString" https://www.example.com
This generally indicates MySQL server connectivity issues or timeouts. Can generally be solved by changing wait_timeout and max_allowed_packet in my.cnf or similar.
I would suggest these values:
wait_timeout = 28800
max_allowed_packet = 8M
$(document).ready(function()
{
$('#yourtext').keyup(function()
{
$(this).val($(this).val().toUpperCase());
});
});
<textarea id="yourtext" rows="5" cols="20"></textarea>
You can also done this by using group by clause
SELECT purchases.address_id, purchases.* FROM "purchases"
WHERE "purchases"."product_id" = 1 GROUP BY address_id,
purchases.purchased_at ORDER purchases.purchased_at DESC
The accepted answer is shortsighted and the question a bit loose in that:
1) Neither explicitly mention whether a covering index is present in the left, right, or both sides.
2) Neither takes into account the size of input left side set and input right side set.
(The question just mentions an overall large result set).
I believe the optimizer is smart enough to convert between "in" vs "exists" when there is a significant cost difference due to (1) and (2), otherwise it may just be used as a hint (e.g. exists to encourage use of an a seekable index on the right side).
Both forms can be converted to join forms internally, have the join order reversed, and run as loop, hash or merge--based on the estimated row counts (left and right) and index existence in left, right, or both sides.
Try this command:

My problem is multi modules project with base module, app module and feature module. Each module has AndroidManifest of its own, and I implemented build variant for debug and main. So we must sure that "android:name" just declared in Manifest of debug and main only, and do not set it in any of Manifest in child module. Ex: Manifest in main:
<application
android:name=".App"/>
Manifest in debug:
<application
tools:replace="android:name"
android:name=".DebugApp"
/>
Do not set "android:name" in other Manifest files like this:
<application android:name=".App">
Just define in feature module like this and it will merged fine
<application>

Something I recently discovered for styling Radio Buttons AND Checkboxes. Before, I had to use jQuery and other things. But this is stupidly simple.
input[type=radio] {
padding-left:5px;
padding-right:5px;
border-radius:15px;
-webkit-appearance:button;
border: double 2px #00F;
background-color:#0b0095;
color:#FFF;
white-space: nowrap;
overflow:hidden;
width:15px;
height:15px;
}
input[type=radio]:checked {
background-color:#000;
border-left-color:#06F;
border-right-color:#06F;
}
input[type=radio]:hover {
box-shadow:0px 0px 10px #1300ff;
}
You can do the same for a checkbox, obviously change the input[type=radio]
to input[type=checkbox]
and change border-radius:15px;
to border-radius:4px;
.
Hope this is somewhat useful to you.
You can use ORDER BY
clause to sort data rows by values in columns. Something like
=QUERY(responses!A1:K; "Select C, D, E where B contains '2nd Web Design' Order By C, D")
If you’d like to order by some columns descending, others ascending, you can add desc
/asc
, ie:
=QUERY(responses!A1:K; "Select C, D, E where B contains '2nd Web Design' Order By C desc, D")
As of ECMAScript 2016 you can use includes()
arr.includes(obj);
If you want to support IE or other older browsers:
function include(arr,obj) {
return (arr.indexOf(obj) != -1);
}
EDIT: This will not work on IE6, 7 or 8 though. The best workaround is to define it yourself if it's not present:
Mozilla's (ECMA-262) version:
if (!Array.prototype.indexOf)
{
Array.prototype.indexOf = function(searchElement /*, fromIndex */)
{
"use strict";
if (this === void 0 || this === null)
throw new TypeError();
var t = Object(this);
var len = t.length >>> 0;
if (len === 0)
return -1;
var n = 0;
if (arguments.length > 0)
{
n = Number(arguments[1]);
if (n !== n)
n = 0;
else if (n !== 0 && n !== (1 / 0) && n !== -(1 / 0))
n = (n > 0 || -1) * Math.floor(Math.abs(n));
}
if (n >= len)
return -1;
var k = n >= 0
? n
: Math.max(len - Math.abs(n), 0);
for (; k < len; k++)
{
if (k in t && t[k] === searchElement)
return k;
}
return -1;
};
}
Daniel James's version:
if (!Array.prototype.indexOf) {
Array.prototype.indexOf = function (obj, fromIndex) {
if (fromIndex == null) {
fromIndex = 0;
} else if (fromIndex < 0) {
fromIndex = Math.max(0, this.length + fromIndex);
}
for (var i = fromIndex, j = this.length; i < j; i++) {
if (this[i] === obj)
return i;
}
return -1;
};
}
roosteronacid's version:
Array.prototype.hasObject = (
!Array.indexOf ? function (o)
{
var l = this.length + 1;
while (l -= 1)
{
if (this[l - 1] === o)
{
return true;
}
}
return false;
} : function (o)
{
return (this.indexOf(o) !== -1);
}
);
varchar(10) will store 10 characters, which may be more than 10 bytes. In indexes, it will allocate the maximium length of the field - so if you are using UTF8-mb4, it will allocate 40 bytes for the 10 character field.
I had similar issue when using an assigned folder for multiple downloads, and I had to append the data path manually:
single download, can be achived as followed (works)
import os as _os
from nltk.corpus import stopwords
from nltk import download as nltk_download
nltk_download('stopwords', download_dir=_os.path.join(get_project_root_path(), 'temp'), raise_on_error=True)
stop_words: list = stopwords.words('english')
This code works, meaning that nltk remembers the download path passed in the download fuction. On the other nads if I download a subsequent package I get similar error as described by user:
Multiple downloads raise an error:
import os as _os
from nltk.corpus import stopwords
from nltk.tokenize import word_tokenize
from nltk import download as nltk_download
nltk_download(['stopwords', 'punkt'], download_dir=_os.path.join(get_project_root_path(), 'temp'), raise_on_error=True)
print(stopwords.words('english'))
print(word_tokenize("I am trying to find the download path 99."))
Error:
Resource punkt not found. Please use the NLTK Downloader to obtain the resource:
import nltk nltk.download('punkt')
Now if I append the ntlk data path with my download path, it works:
import os as _os
from nltk.corpus import stopwords
from nltk.tokenize import word_tokenize
from nltk import download as nltk_download
from nltk.data import path as nltk_path
nltk_path.append( _os.path.join(get_project_root_path(), 'temp'))
nltk_download(['stopwords', 'punkt'], download_dir=_os.path.join(get_project_root_path(), 'temp'), raise_on_error=True)
print(stopwords.words('english'))
print(word_tokenize("I am trying to find the download path 99."))
This works... Not sure why works in one case but not the other, but error message seems to imply that it doesn't check into the download folder the second time. NB: using windows8.1/python3.7/nltk3.5
how do I change the floating label text color?
With the Material Components library you can customize the TextInputLayout
the hint text color using (it requires the version 1.1.0)
In the layout:
app:hintTextColor
attribute : the color of the label when it is collapsed and the text field is active
android:textColorHint
attribute: the color of the label in all other text field states (such as resting and disabled)
<com.google.android.material.textfield.TextInputLayout
app:hintTextColor="@color/mycolor"
android:textColorHint="@color/text_input_hint_selector"
.../>
Widget.MaterialComponents.TextInputLayout.*
:<style name="MyFilledBox" parent="Widget.MaterialComponents.TextInputLayout.FilledBox">
<item name="hintTextColor">@color/mycolor</item>
<item name="android:textColorHint">@color/text_input_hint_selector</item>
</style>
The default selector for android:textColorHint
is:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:alpha="0.38" android:color="?attr/colorOnSurface" android:state_enabled="false"/>
<item android:alpha="0.6" android:color="?attr/colorOnSurface"/>
</selector>
Byterbit solution is problematic because:
for cookies, setting expiration via session.cookie_lifetime is the right solution design-wise and security-wise! for expiring the session, you can use session.gc_maxlifetime.
expiring the cookies by calling session_destroy might yield unpredictable results because they might have already been expired.
making the change in php.ini is also a valid solution but it makes the expiration global for the entire domain which might not be what you really want - some pages might choose to keep some cookies more than others.

Bonus: why do people seemingly always use big-oh when talking informally?
Because in big-oh, this loop:
for i = 1 to n do
something in O(1) that doesn't change n and i and isn't a jump
is O(n), O(n^2), O(n^3), O(n^1423424)
. big-oh is just an upper bound, which makes it easier to calculate because you don't have to find a tight bound.
The above loop is only big-theta(n)
however.
What's the complexity of the sieve of eratosthenes? If you said O(n log n)
you wouldn't be wrong, but it wouldn't be the best answer either. If you said big-theta(n log n)
, you would be wrong.

I've just had some of the similar problems with scrollTop

There's more to this than you realize, you have to remember than an activity that is launched does not implicitly destroy the calling activity. Sure, you can set it up such that your user clicks a button to go to a page, you start that page's activity and destroy the current one. This causes a lot of overhead. The best guide I can give you is:
** Start a new activity only if it makes sense to have the main activity and this one open at the same time (think of multiple windows).
A great example of when it makes sense to have multiple activities is Google Drive. The main activity provides a file explorer. When a file is opened, a new activity is launched to view that file. You can press the recent apps button which will allow you to go back to the browser without closing the opened document, then perhaps even open another document in parallel to the first.
My VPS is set to disable the following functions:
root@vps [~]# grep disable_functions /usr/local/lib/php.ini
disable_functions = dl, exec, shell_exec, system, passthru, popen, pclose, proc_open, proc_nice, proc_terminate, proc_get_status, proc_close, pfsockopen, leak, apache_child_terminate, posix_kill, posix_mkfifo, posix_setpgid, posix_setsid, posix_setuid
PHP has enough potentially destructible functions that your list might be too big to grep for. For example, PHP has chmod and chown, which could be used to simply deactivate a website.
EDIT: Perhaps you may want to build a bash script that searches for a file for an array of functions grouped by danger (functions that are bad, functions that are worse, functions that should never be used), and then calculate the relativity of danger that the file imposes into a percentage. Then output this to a tree of the directory with the percentages tagged next to each file, if greater than a threshold of say, 30% danger.
Try this, it will work for sure.
When writing Rails migrations to convert a string column to an integer you'd usually say:
change_column :table_name, :column_name, :integer
However, PostgreSQL will complain:
PG::DatatypeMismatch: ERROR: column "column_name" cannot be cast automatically to type integer
HINT: Specify a USING expression to perform the conversion.
The "hint" basically tells you that you need to confirm you want this to happen, and how data shall be converted. Just say this in your migration:
change_column :table_name, :column_name, 'integer USING CAST(column_name AS integer)'
The above will mimic what you know from other database adapters. If you have non-numeric data, results may be unexpected (but you're converting to an integer, after all).
There's also a C standard built-in library to get command line arguments: getopt
You can check it on Wikipedia or in Argument-parsing helpers for C/Unix.
It's important to evaluate the different ways you can create an HttpClient, and part of that is understanding HttpClientFactory.
This is not a direct answer I know - but you're better off starting here than ending up with new HttpClient(...)
everywhere.
Firefox 3 doesn't seem to have a problem with huge numbers.
1e+200 * 1e+100 will calculate fine to 1e+300.
Safari seem to have no problem with it as well. (For the record, this is on a Mac if anyone else decides to test this.)
Unless I lost my brain at this time of day, this is way bigger than a 64-bit integer.
Ctrl + Break works, but only if the Build window is active. Also, interrupting the build will sometimes leave a corrupted .obj
file that will have to be manually deleted in order for the build to proceed.
What you are doing is to look for (0) or (1) results.
(cnt >= 10 && cnt <= 20) returns either true or false.
--edit-- you can't use case with boolean (logic) experessions. The statement cnt >= 10 returns zero for false or one for true. Hence, it will we case(1) or case(0) which will never match to the length. --edit--
One option would be to include function.cpp
in your UnitTest1
project, but that may not be the most ideal solution structure. The short answer to your problem is that when building your UnitTest1
project, the compiler and linker have no idea that function.cpp
exists, and also have nothing to link that contains a definition of multiple
. A way to fix this is making use of linking libraries.
Since your unit tests are in a different project, I'm assuming your intention is to make that project a standalone unit-testing program. With the functions you are testing located in another project, it's possible to build that project to either a dynamically or statically linked library. Static libraries are linked to other programs at build time, and have the extension .lib
, and dynamic libraries are linked at runtime, and have the extension .dll
. For my answer I'll prefer static libraries.
You can turn your first program into a static library by changing it in the projects properties. There should be an option under the General tab where the project is set to build to an executable (.exe
). You can change this to .lib
. The .lib
file will build to the same place as the .exe
.
In your UnitTest1
project, you can go to its properties, and under the Linker tab in the category Additional Library Directories, add the path to which MyProjectTest
builds. Then, for Additional Dependencies under the Linker - Input tab, add the name of your static library, most likely MyProjectTest.lib
.
That should allow your project to build. Note that by doing this, MyProjectTest
will not be a standalone executable program unless you change its build properties as needed, which would be less than ideal.
Quick simple example using mongo, for an API that provides user auth for ie Angular client
in app.js
var express = require('express');
var MongoStore = require('connect-mongo')(express);
// ...
app.use(express.cookieParser());
// obviously change db settings to suit
app.use(express.session({
secret: 'blah1234',
store: new MongoStore({
db: 'dbname',
host: 'localhost',
port: 27017
})
}));
app.use(app.router);
for your route something like this:
// (mongo connection stuff)
exports.login = function(req, res) {
var email = req.body.email;
// use bcrypt in production for password hashing
var password = req.body.password;
db.collection('users', function(err, collection) {
collection.findOne({'email': email, 'password': password}, function(err, user) {
if (err) {
res.send(500);
} else {
if(user !== null) {
req.session.user = user;
res.send(200);
} else {
res.send(401);
}
}
});
});
};
Then in your routes that require auth you can just check for the user session:
if (!req.session.user) {
res.send(403);
}
I don't know the MOST efficient method, but I'd do the following:
Should work \o/
If you need, I can code something up tomorrow in C to demonstrate.
You need a reference to an Axes

Inside our activity we can get the root
view with:
ViewGroup rootView = (ViewGroup) ((ViewGroup) this
.findViewById(android.R.id.content)).getChildAt(0);
or
View rootView = getWindow().getDecorView().getRootView();
Python has three modes via., private, public and protected .While importing a module only public mode is accessible .So private and protected modules cannot be called from outside of the module i.e., when it is imported .
BundleConfig
is nothing more than bundle configuration moved to separate file. It used to be part of app startup code (filters, bundles, routes used to be configured in one class)
To add this file, first you need to add the Microsoft.AspNet.Web.Optimization
nuget package to your web project:
Install-Package Microsoft.AspNet.Web.Optimization
Then under the App_Start folder create a new cs file called BundleConfig.cs
. Here is what I have in my mine (ASP.NET MVC 5, but it should work with MVC 4):
using System.Web;
using System.Web.Optimization;
namespace CodeRepository.Web
{
public class BundleConfig
{
// For more information on bundling, visit http://go.microsoft.com/fwlink/?LinkId=301862
public static void RegisterBundles(BundleCollection bundles)

Don't know exactly what kind of dataset you have, so I provide general answer.
x <- c(1,2,NA,3,4,5)
y <- c(1,2,3,NA,6,8)
my.data <- data.frame(x, y)
> my.data
x y
1 1 1
2 2 2
3 NA 3
4 3 NA
5 4 6
6 5 8
# Exclude rows with NA values
my.data[complete.cases(my.data),]
x y
1 1 1
2 2 2

6 5 8
You need commas after end
finishing the case statement. And, the "as" goes after the case
statement, not inside it:
Insert into TblStuff(FullName, Address, City, Zip)
Select (Case When Middle is Null Then Fname + LName
Else Fname +' ' + Middle + ' '+ Lname
End) as FullName,
(Case When Address2 is Null Then Address1
else Address1 +', ' + Address2
End) as Address,
City as City,
Zip as Zip

Put your TableLayout inside a ScrollView Layout.That will solve your problem.
No.
If the user is sophisticated or determined enough to:
then they are probably sophisticated or determined enough to:
So what's on this hidden sheet? Proprietary information like price formulas, or client names, or employee salaries? Putting that info in even an hidden tab probably isn't the greatest idea to begin with.
I really liked the answer of RichieHindle, however I liked the question as an exercise. Here's a brute force implementation using strings:)
import random
first = random.randint(1,9)
first = str(first)
n = 5
nrs = [str(random.randrange(10)) for i in range(n-1)]
for i in range(len(nrs)) :
first += str(nrs[i])
print str(first)
Ajax.BeginForm looks to be a fail.
Using a regular Html.Begin for, this does the trick just nicely:
$('#detailsform').submit(function(e) {
e.preventDefault();
$.post($(this).attr("action"), $(this).serialize(), function(r) {
$("#edit").html(r);
});
});
List<Conversation> conversations = **jdbcTemplate**.**queryForList**(
**SQL_QUERY**,
new Object[] {userId, dateFrom, dateTo}); //placeholders values
Suppose the sql query is like
SQL_QUERY = "**select** info,count(*),IF(info is null , 'DATA' , 'NO DATA') **from** table where userId=? , dateFrom=? , dateTo=?";
**HERE userId=? , dateFrom=? , dateTo=?**
the question marks are place holders
**SQL_QUERY**,
new Object[] {userId, dateFrom, dateTo});
It will go as an object array along with the sql query
I have a similar issue, have you tried:
proxy.ClientCredentials.Windows.AllowedImpersonationLevel =
System.Security.Principal.TokenImpersonationLevel.Impersonation;
Just use: android:layout_centerHorizontal="true"
It will put the whole textview in the center
You get and format like this
for /f "tokens=1-4 delims=/ " %%i in ("%date%") do (
set dow=%%i
set month=%%j
set day=%%k
set year=%%l
)
set datestr=%month%_%day%_%year%
echo datestr is %datestr%
Note: Above only works on US locale. It assumes the output of echo %date%
looks like this: Thu 02/13/21
. If you have different Windows locale settings, you will need to modify the script based on your configuration.
With flexbox this is easy:
Just add the following to the image container:
.img-container {
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
display: flex; /* add */
justify-content: center; /* add to align horizontal */
align-items: center; /* add to align vertical */
}
I spent literally a day trying to resolve this.
The only thing that worked was deleting the .sln file, creating a new one, and adding the projects back in one by one.
¯\_(?)_/¯ - Programming - ¯\_(?)_/¯
I use this.
public static byte[] toByteArray(InputStream is) throws IOException {
ByteArrayOutputStream output = new ByteArrayOutputStream();
try {
byte[] b = new byte[4096];
int n = 0;
while ((n = is.read(b)) != -1) {
output.write(b, 0, n);
}
return output.toByteArray();
} finally {
output.close();
}
}
Take a look at http://jsfiddle.net/TroyAlford/ZZEk8/ for a working example of the below:
<img id='myImg' src='/my/img/link.gif' />
<script type="text/javascript">
$(document).bind('click', function () {
// Add a click-handler to the image.
$('#myImg').bind('click', function (ev) {
var $img = $(ev.target);
var offset = $img.offset();
var x = ev.clientX - offset.left;
var y = ev.clientY - offset.top;
alert('clicked at x: ' + x + ', y: ' + y);
});
});
</script>
Note that the above will get you the x and the y relative to the image's box - but will not correctly take into account margin, border and padding. These elements aren't actually part of the image, in your case - but they might be part of the element that you would want to take into account.
In this case, you should also use $div.outerWidth(true) - $div.width()
and $div.outerHeight(true) - $div.height()
to calculate the amount of margin / border / etc.
Your new code might look more like:
<img id='myImg' src='/my/img/link.gif' />
<script type="text/javascript">
$(document).bind('click', function () {
// Add a click-handler to the image.
$('#myImg').bind('click', function (ev) {
var $img = $(ev.target);
var offset = $img.offset(); // Offset from the corner of the page.
var xMargin = ($img.outerWidth() - $img.width()) / 2;
var yMargin = ($img.outerHeight() - $img.height()) / 2;
// Note that the above calculations assume your left margin is
// equal to your right margin, top to bottom, etc. and the same
// for borders.
var x = (ev.clientX + xMargin) - offset.left;
var y = (ev.clientY + yMargin) - offset.top;
alert('clicked at x: ' + x + ', y: ' + y);
});
});
</script>
Aircoded (but tested on this fiddle)

var $elem = $(this);
$elem.data('mouseheld_timeout', setTimeout(function() {

I had the same problem and it turned out that my image names included special characters (e.g. château.jpg), which could not bet handled by cv2.imread
. My solution was to make a temporary copy of the file, renaming it e.g. temp.jpg, which could be loaded by cv2.imread
without any problems.
Note: I did not check the performance of shutil.copy2
vice versa other options. So probably there is a better/faster solution to make a temporary copy.
import shutil, sys, os, dlib, glob, cv2
for f in glob.glob(os.path.join(myfolder_path, "*.jpg")):
shutil.copy2(f, myfolder_path + 'temp.jpg')
img = cv2.imread(myfolder_path + 'temp.jpg')
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
os.remove(myfolder_path + 'temp.jpg')
If there are only few files with special characters, renaming can also be done as an exeption, e.g.
for f in glob.glob(os.path.join(myfolder_path, "*.jpg")):
try:
img = cv2.imread(f)
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
except:
shutil.copy2(f, myfolder_path + 'temp.jpg')
img = cv2.imread(myfolder_path + 'temp.jpg')
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
os.remove(myfolder_path + 'temp.jpg')
Disclosure:
But nice because of its simplicity:
import resource
def using(point=""):
usage=resource.getrusage(resource.RUSAGE_SELF)
return '''%s: usertime=%s systime=%s mem=%s mb
'''%(point,usage[0],usage[1],
usage[2]/1024.0 )
Just insert using("Label")
where you want to see what's going on. For example
print(using("before"))
wrk = ["wasting mem"] * 1000000
print(using("after"))
>>> before: usertime=2.117053 systime=1.703466 mem=53.97265625 mb
>>> after: usertime=2.12023 systime=1.70708 mem=60.8828125 mb
The grammar of the language specifies that positional arguments appear before keyword or starred arguments in calls:
argument_list ::= positional_arguments ["," starred_and_keywords]
["," keywords_arguments]
| starred_and_keywords ["," keywords_arguments]
| keywords_arguments
Specifically, a keyword argument looks like this: tag='insider trading!'
while a positional argument looks like this: ..., exchange, ...
. The problem lies in that you appear to have copy/pasted the parameter list, and left some of the default values in place, which makes them look like keyword arguments rather than positional ones. This is fine, except that you then go back to using positional arguments, which is a syntax error.
Also, when an argument has a default value, such as price=None
, that means you don't have to provide it. If you don't provide it, it will use the default value instead.
To resolve this error, convert your later positional arguments into keyword arguments, or, if they have default values and you don't need to use them, simply don't specify them at all:
order_id = kite.order_place(self, exchange, tradingsymbol,
transaction_type, quantity)
# Fully positional:
order_id = kite.order_place(self, exchange, tradingsymbol, transaction_type, quantity, price, product, order_type, validity, disclosed_quantity, trigger_price, squareoff_value, stoploss_value, trailing_stoploss, variety, tag)
# Some positional, some keyword (all keywords at end):
order_id = kite.order_place(self, exchange, tradingsymbol,
transaction_type, quantity, tag='insider trading!')
EDIT: Updated for jQuery 1.8
Since jQuery 1.8 browser specific transformations will be added automatically. jsFiddle Demo
var rotation = 0;
jQuery.fn.rotate = function(degrees) {
$(this).css({'transform' : 'rotate('+ degrees +'deg)'});
return $(this);
};
$('.rotate').click(function() {
rotation += 5;
$(this).rotate(rotation);
});
EDIT: Added code to make it a jQuery function.
For those of you who don't want to read any further, here you go. For more details and examples, read on. jsFiddle Demo.
var rotation = 0;
jQuery.fn.rotate = function(degrees) {
$(this).css({'-webkit-transform' : 'rotate('+ degrees +'deg)',
'-moz-transform' : 'rotate('+ degrees +'deg)',
'-ms-transform' : 'rotate('+ degrees +'deg)',
'transform' : 'rotate('+ degrees +'deg)'});
return $(this);
};
$('.rotate').click(function() {
rotation += 5;
$(this).rotate(rotation);
});
EDIT: One of the comments on this post mentioned jQuery Multirotation. This plugin for jQuery essentially performs the above function with support for IE8. It may be worth using if you want maximum compatibility or more options. But for minimal overhead, I suggest the above function. It will work IE9+, Chrome, Firefox, Opera, and many others.
Bobby... This is for the people who actually want to do it in the javascript. This may be required for rotating on a javascript callback.
Here is a jsFiddle.
If you would like to rotate at custom intervals, you can use jQuery to manually set the css instead of adding a class. Like this! I have included both jQuery options at the bottom of the answer.
HTML
<div class="rotate">
<h1>Rotatey text</h1>
</div>
CSS
/* Totally for style */
.rotate {
background: #F02311;
color: #FFF;
width: 200px;
height: 200px;
text-align: center;
font: normal 1em Arial;
position: relative;
top: 50px;
left: 50px;
}
/* The real code */
.rotated {
-webkit-transform: rotate(45deg); /* Chrome, Safari 3.1+ */
-moz-transform: rotate(45deg); /* Firefox 3.5-15 */
-ms-transform: rotate(45deg); /* IE 9 */
-o-transform: rotate(45deg); /* Opera 10.50-12.00 */
transform: rotate(45deg); /* Firefox 16+, IE 10+, Opera 12.10+ */
}
jQuery
Make sure these are wrapped in $(document).ready
$('.rotate').click(function() {
$(this).toggleClass('rotated');
});
Custom intervals
var rotation = 0;
$('.rotate').click(function() {
rotation += 5;
$(this).css({'-webkit-transform' : 'rotate('+ rotation +'deg)',
'-moz-transform' : 'rotate('+ rotation +'deg)',
'-ms-transform' : 'rotate('+ rotation +'deg)',
'transform' : 'rotate('+ rotation +'deg)'});
});
You can check if Excel is already open. There is no need to create another isntance
If CheckAppOpen("excel.application") Then
'MsgBox "App Loaded"
Set xlApp = GetObject(, "excel.Application")
Else
' MsgBox "App Not Loaded"
Set wrdApp = CreateObject(,"excel.Application")
End If
You need to assign display: block;
property to the wrapping anchor. Otherwise it won't wrap correctly.
<a style="display:block" href="http://justinbieber.com">
<div class="xyz">My div contents</div>
</a>
You can convert CSV string to Array with this function.
function csv2array(
$csv_string,
$delimiter = ",",
$skip_empty_lines = true,
$trim_fields = true,
$FirstLineTitle = false
) {
$arr = array_map(
function ( $line ) use ( &$result, &$FirstLine, $delimiter, $trim_fields, $FirstLineTitle ) {
if ($FirstLineTitle && !$FirstLine) {
$FirstLine = explode( $delimiter, $result[0] );
}
$lineResult = array_map(
function ( $field ) {
return str_replace( '!!Q!!', '"', utf8_decode( urldecode( $field ) ) );
},
$trim_fields ? array_map( 'trim', explode( $delimiter, $line ) ) : explode( $delimiter, $line )
);
return $FirstLineTitle ? array_combine( $FirstLine, $lineResult ) : $lineResult;
},
($result = preg_split(
$skip_empty_lines ? ( $trim_fields ? '/( *\R)+/s' : '/\R+/s' ) : '/\R/s',
preg_replace_callback(
'/"(.*?)"/s',
function ( $field ) {
return urlencode( utf8_encode( $field[1] ) );
},
$enc = preg_replace( '/(?<!")""/', '!!Q!!', $csv_string )
)
))
);
return $FirstLineTitle ? array_splice($arr, 1) : $arr;
}

If you are in .NET stack with MVC with AngularJS, this is what you have to do to remove the '#' from url:
Set up your base href in your _Layout page: <head> <base href="/"> </head>
Then, add following in your angular app config : $locationProvider.html5Mode(true)
Above will remove '#' from url but page refresh won't work e.g. if you are in "yoursite.com/about" page refresh will give you a 404. This is because MVC does not know about angular routing and by MVC pattern it will look for a MVC page for 'about' which does not exists in MVC routing path. Workaround for this is to send all MVC page request to a single MVC view and you can do that by adding a route that catches all url
routes.MapRoute(
name: "App",
url: "{*url}",
defaults: new { controller = "Home", action = "Index" }
);
In the first one Python has to execute one more operations than necessary(instead of just checking not equal to it has to check if it is not true that it is equal, thus one more operation). It would be impossible to tell the difference from one execution, but if run many times, the second would be more efficient. Overall I would use the second one, but mathematically they are the same
You might want to change the DNS settings of the Docker daemon. You can edit (or create) the configuration file at /etc/docker/daemon.json
with the dns key, as
{
"dns": ["your_dns_address", "8.8.8.8"]
}
In the example above, the first element of the list is the address of your DNS server. The second item is the Google’s DNS which can be used when the first one is not available.
Before proceeding, save daemon.json and restart the docker service.
sudo service docker restart
Once fixed, retry to run the build command.
Thank you, Erik, for posting this. This worked for me. I'd like to add a note about an extra step I needed. Within "Payload/Application.app/" there was a directory named "CACertChains" that contained a file named "cacert.pem". I had to remove the directory and the .pem to complete these steps. Thanks again! –
Depends in how you are hiding your div, diplay=none
is different of visibility=hidden
and the opacity=0
Visibility then use ...style.visibility='visible'
Display then use ...style.display='block'
(or others depends how
you setup ur css, inline, inline-block, flex...)
Opacity then use ...style.opacity='1';
// forcibly remove and reinstall all package dependencies
ren package.json package.json-bak
echo {} > package.json
npm prune
del package.json
ren package.json-bak package.json
npm i
This essentially creates a fake, empty package.json, calls npm prune
to remove everything in node_modules, restores the original package.json and re-installs everything.
Some of the other solutions might be more elegant, but I suspect this is faster and exhaustive. On other threads I've seen people suggest just deleting the node_modules directory, but at least for windows, this causes npm to choke afterward because the bin directory goes missing. Maybe on linux it gets restored properly, but not windows.
The best way to hide all items in a menu with just one command is to use "group" on your menu xml. Just add all menu items that will be in your overflow menu inside the same group.
In this example we have two menu items that will always show (regular item and search) and three overflow items:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/someItemNotToHide1"
android:title="ITEM"
app:showAsAction="always" />
<item
android:id="@+id/someItemNotToHide2"
android:icon="@android:drawable/ic_menu_search"
app:showAsAction="collapseActionView|ifRoom"
app:actionViewClass="android.support.v7.widget.SearchView"
android:title="Search"/>
<group android:id="@+id/overFlowItemsToHide">
<item android:id="@+id/someID"
android:orderInCategory="1" app:showAsAction="never" />
<item android:id="@+id/someID2"
android:orderInCategory="1" app:showAsAction="never" />
<item android:id="@+id/someID3"
android:orderInCategory="1" app:showAsAction="never" />
</group>
</menu>
Then, on your activity (preferable at onCreateOptionsMenu), use command setGroupVisible to set all menu items visibility to false or true.
public boolean onCreateOptionsMenu(Menu menu) {
menu.setGroupVisible(R.id.overFlowItems, false); // Or true to be visible
}
If you want to use this command anywhere else on your activity, be sure to save menu class to local, and always check if menu is null, because you can execute before createOptionsMenu:
Menu menu;
public boolean onCreateOptionsMenu(Menu menu) {
this.menu = menu;
}
public void hideMenus() {
if (menu != null) menu.setGroupVisible(R.id.overFlowItems, false); // Or true to be visible
}
What I did was first updating the pip by using the command:
pip install --upgrade pip
and then I also installed wheel by using command: pip install wheel
and then it worked perfectly Fine.
Hope it works for you I guess.
app.use(function(req, res, next) {
var allowedOrigins = [
"http://localhost:4200"
];
var origin = req.headers.origin;
console.log(origin)
console.log(allowedOrigins.indexOf(origin) > -1)
// Website you wish to allow to
if (allowedOrigins.indexOf(origin) > -1) {
res.setHeader("Access-Control-Allow-Origin", origin);
}
// res.setHeader("Access-Control-Allow-Origin", "http://localhost:4200");
// Request methods you wish to allow
res.setHeader(
"Access-Control-Allow-Methods",
"GET, POST, OPTIONS, PUT, PATCH, DELETE"
);
// Request headers you wish to allow
res.setHeader(
"Access-Control-Allow-Headers",
"X-Requested-With,content-type,Authorization"
);
// Set to true if you need the website to include cookies in the requests sent
// to the API (e.g. in case you use sessions)
res.setHeader("Access-Control-Allow-Credentials", true);
// Pass to next layer of middleware
next();
});
Add this code in your index.js or server.js file and change the allowed origin array according to your requirement.

There are many ways to run javascript in Visual Studio Code.
If you use Node, then I recommend use the standard debugger in VSC.
I normally create a dummy file, like test.js where I do external tests.
In your folder where you have your code, you create a folder called ".vscode" and create a file called "launch.json"
In this file you paste the following and save. Now you have two options to test your code.
When you choose "Nodemon Test File" you need to put your code to test in test.js.
To install nodemon and more info on how to debug with nodemon in VSC I recommend to read this article, which explain in more detail the second part on the launch.json file and how to debug in ExpressJS.
{
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"name": "Nodemon Test File",
"runtimeExecutable": "nodemon",
"program": "${workspaceFolder}/test.js",
"restart": true,
"console": "integratedTerminal",
"internalConsoleOptions": "neverOpen"
},
{
"type": "node",
"request": "attach",

"processId": "${command:PickProcess}",

I've created a little Powershell function to emulate MSDOS pause
. This handles whether running Powershell ISE or non ISE. (ReadKey
does not work in powershell ISE). When running Powershell ISE, this function opens a Windows MessageBox
. This can sometimes be confusing, because the MessageBox
does not always come to the forefront. Anyway, here it goes:
Usage:
pause "Press any key to continue"
Function definition:
Function pause ($message)
{
# Check if running Powershell ISE
if ($psISE)
{
Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.MessageBox]::Show("$message")
}
else
{
Write-Host "$message" -ForegroundColor Yellow
$x = $host.ui.RawUI.ReadKey("NoEcho,IncludeKeyDown")
}
}
Just delete key:
HKEY_CURRENT_USER/Software/Microsoft/VCExpress/9.0/Registration
Or run in command line:
reg delete HKCU\Software\Microsoft\VCExpress\9.0\Registration /f
I want to point a different view on this general naming convention, e.g.:
see java.util.Set: boolean add?(E e)
where the rationale is:
do some processing then report whether it succeeded or not.
While the return
is indeed a boolean
the method's name should point the processing to complete instead of the result type (boolean for this example).
Your createFreshSnapshot
example seems for me more related to this point of view because seems to mean this: create a fresh-snapshot then report whether the create-operation succeeded. Considering this reasoning the name createFreshSnapshot
seems to be the best one for your situation.
I would suggest a two step query
I'm assuming you have an autoincrementing primary key because you say your PK is (max+1) which sounds like the definition of an autioincrementing key.
I'm calling the PK id
, substitute with whatever your PK is called.
1 - figure out the primary key number for column 1000.
SELECT @id:= id FROM smartmeter_usage LIMIT 1 OFFSET 1000
2 - update the table.
UPDATE smartmeter_usage.users_reporting SET panel_id = 3
WHERE panel_id IS NULL AND id >= @id
ORDER BY id
LIMIT 1000
Please test to see if I didn't make an off-by-one error; you may need to add or subtract 1 somewhere.
Ok i was previously not aware that AngularJS
usually refers to Angular
v1 version and only Angular to Angular v2+
This answer only applies for Angular
Leaving this here for future reference..
Not sure how it works for you guys but on Angular 9 i have to wrap ngStyle in brackets like this:
[ng-style]="{ 'width' : (myObject.value == 'ok') ? '100%' : '0%' }"
Otherwise it doesn't work
You can use the WinSPC program. Its access to any server is pretty easy. The program gives its guide too. I hope it's helpfull.
Using AES or implementing AES? To use AES, there is the System.Security.Cryptography.RijndaelManaged class.
If you use very big enum types then, following can be useful;
public enum deneme {
UPDATE, UPDATE_FAILED;
private static Map<Integer, deneme> ss = new TreeMap<Integer,deneme>();
private static final int START_VALUE = 100;
private int value;
static {
for(int i=0;i<values().length;i++)

This is quite simple. You have to call cancel
or cancelAll
on your NotificationManager. The parameter of the cancel method is the ID of the notification that should be canceled.
See the API: http://developer.android.com/reference/android/app/NotificationManager.html#cancel(int)
Your solution makes use of an extension to GROUP BY clause that permits to group by some fields (in this case, just post_author
):
GROUP BY wp_posts.post_author
and select nonaggregated columns:
SELECT wp_posts.*
that are not listed in the group by clause, or that are not used in an aggregate function (MIN, MAX, COUNT, etc.).
Correct use of extension to GROUP BY clause
This is useful when all values of non-aggregated columns are equal for every row.
For example, suppose you have a table GardensFlowers
(name
of the garden, flower
that grows in the garden):
INSERT INTO GardensFlowers VALUES
('Central Park', 'Magnolia'),
('Hyde Park', 'Tulip'),
('Gardens By The Bay', 'Peony'),
('Gardens By The Bay', 'Cherry Blossom');
and you want to extract all the flowers that grows in a garden, where multiple flowers grow. Then you have to use a subquery, for example you could use this:
SELECT GardensFlowers.*
FROM GardensFlowers
WHERE name IN (SELECT name
FROM GardensFlowers
GROUP BY name
HAVING COUNT(DISTINCT flower)>1);
If you need to extract all the flowers that are the only flowers in the garder instead, you could just change the HAVING condition to HAVING COUNT(DISTINCT flower)=1
, but MySql also allows you to use this:
SELECT GardensFlowers.*
FROM GardensFlowers
GROUP BY name
HAVING COUNT(DISTINCT flower)=1;
no subquery, not standard SQL, but simpler.
Incorrect use of extension to GROUP BY clause
But what happens if you SELECT non-aggregated columns that are non equal for every row? Which is the value that MySql chooses for that column?
It looks like MySql always chooses the FIRST value it encounters.
To make sure that the first value it encounters is exactly the value you want, you need to apply a GROUP BY
to an ordered query, hence the need to use a subquery. You can't do it otherwise.
Given the assumption that MySql always chooses the first row it encounters, you are correcly sorting the rows before the GROUP BY. But unfortunately, if you read the documentation carefully, you'll notice that this assumption is not true.
When selecting non-aggregated columns that are not always the same, MySql is free to choose any value, so the resulting value that it actually shows is indeterminate.
I see that this trick to get the first value of a non-aggregated column is used a lot, and it usually/almost always works, I use it as well sometimes (at my own risk). But since it's not documented, you can't rely on this behaviour.
This link (thanks ypercube!) GROUP BY trick has been optimized away shows a situation in which the same query returns different results between MySql and MariaDB, probably because of a different optimization engine.
So, if this trick works, it's just a matter of luck.
The accepted answer on the other question looks wrong to me:
HAVING wp_posts.post_date = MAX(wp_posts.post_date)
wp_posts.post_date
is a non-aggregated column, and its value will be officially undetermined, but it will likely be the first post_date
encountered. But since the GROUP BY trick is applied to an unordered table, it is not sure which is the first post_date
encountered.
It will probably returns posts that are the only posts of a single author, but even this is not always certain.
A possible solution
I think that this could be a possible solution:
SELECT wp_posts.*
FROM wp_posts
WHERE id IN (
SELECT max(id)
FROM wp_posts
WHERE (post_author, post_date) = (
SELECT post_author, max(post_date)
FROM wp_posts
WHERE wp_posts.post_status='publish'
AND wp_posts.post_type='post'
GROUP BY post_author
) AND wp_posts.post_status='publish'
AND wp_posts.post_type='post'
GROUP BY post_author
)
On the inner query I'm returning the maximum post date for every author. I'm then taking into consideration the fact that the same author could theorically have two posts at the same time, so I'm getting only the maximum ID. And then I'm returning all rows that have those maximum IDs. It could be made faster using joins instead of IN clause.
(If you're sure that ID
is only increasing, and if ID1 > ID2
also means that post_date1 > post_date2
, then the query could be made much more simple, but I'm not sure if this is the case).
Let's say you have this
A
|
B A0
| |
C D
\ /
|
...
And you want to make sure that A
is the same as A0
.
This will do the trick:
$ git diff B A > B-A.diff
$ git diff D A0 > D-A0.diff
$ diff B-A.diff D-A0.diff
How about with a :before
pseudoelement:
a:before {
content: '\a';
white-space: pre;
}
A persistent context represents the entities which hold data and are qualified to be persisted in some persistent storage like a database. Once we commit
a transaction under a session which has these entities attached with, Hibernate flushes the persistent context and changes(insert/save, update or delete) on them are persisted in the persistent storage.
I used the advice of Kevin Jones above with the following --skip-networking change for slightly better security:
sudo systemctl set-environment MYSQLD_OPTS="--skip-grant-tables --skip-networking"
[user@machine ~]$ mysql -u root
Then when attempting to reset the password I received an error, but googling elsewhere suggested I could simply forge ahead. The following worked:
mysql> select user(), current_user();
+--------+-----------------------------------+
| user() | current_user() |
+--------+-----------------------------------+
| root@ | skip-grants user@skip-grants host |
+--------+-----------------------------------+
1 row in set (0.00 sec)
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'sup3rPw#'
ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.02 sec)
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'sup3rPw#'
Query OK, 0 rows affected (0.08 sec)
mysql> exit
Bye
[user@machine ~]$ systemctl stop mysqld
[user@machine ~]$ sudo systemctl unset-environment MYSQLD_OPTS
[user@machine ~]$ systemctl start mysqld
At that point I was able to log in.
I set a width value just for the first item (>= a width) and a minimum distance between each item (>= a distance). Then I use Ctrl to drag second, third... item on the first one to chain dependencies among the items.
As mentioned in the previous posts, using an HttpServletReqiestWrapper is the way to go, however the missed part in those posts was that apart from overriding the method getParameter(), you should also override other parameter related methods to produce a consistent response. e.g. the value of a param added by the custom request wrapper should also be included in the parameters map returned by the method getParameterMap(). Here is an example:
public class AddableHttpRequest extends HttpServletRequestWrapper {
/** A map containing additional request params this wrapper adds to the wrapped request */
private final Map<String, String> params = new HashMap<>();
/**
* Constructs a request object wrapping the given request.
* @throws java.lang.IllegalArgumentException if the request is null
*/
AddableHttpRequest(final HttpServletRequest request) {
super(request)
}
@Override
public String getParameter(final String name) {
// if we added one with the given name, return that one
if ( params.get( name ) != null ) {
return params.get( name );
} else {
// otherwise return what's in the original request
return super.getParameter(name);
}
}
/**
* *** OVERRIDE THE METHODS BELOW TO REFLECT PARAMETERS ADDED BY THIS WRAPPER ****
*/
@Override
public Map<String, String> getParameterMap() {
// defaulf impl, should be overridden for an approprivate map of request params
return super.getParameterMap();
}
@Override
public Enumeration<String> getParameterNames() {
// defaulf impl, should be overridden for an approprivate map of request params names
return super.getParameterNames();
}
@Override
public String[] getParameterValues(final String name) {
// defaulf impl, should be overridden for an approprivate map of request params values
return super.getParameterValues(name);
}
}
Here the steps I used to fix the warning:
Since pandas 1.0 it became much more straightforward. This will read column 'ID' as dtype 'string':
pd.read_csv('sample.csv',dtype={'ID':'string'})
As we can see in this Getting started guide, 'string' dtype has been introduced (before strings were treated as dtype 'object').
use
sudo pip install virtualenv
You have a permission denied error. This states your current user does not have the root permissions.So run the command as a super user.
You may use clone()
which works well if your object has immutable objects and/or primitives, but it may be a little problematic when you don't have these ( such as collections ) for which you may need to perform a deep clone.
User userCopy = (User) user.clone();//make a copy
for(...) {
user.age = 1;
user.id = -1;
UserDao.update(user)
user = userCopy;
}
It seems like you just want to preserve the attributes: age
and id
which are of type int
so, why don't you give it a try and see if it works.
For more complex scenarios you could create a "copy" method:
publc class User {
public static User copy( User other ) {
User newUser = new User();
newUser.age = other.age;
newUser.id = other.id;
//... etc.
return newUser;
}
}
It should take you about 10 minutes.
And then you can use that instead:
User userCopy = User.copy( user ); //make a copy
// etc.
To read more about clone read this chapter in Joshua Bloch "Effective Java: Override clone judiciously"
First check To see how many aliases you have and what are they, you can initiate this command git remote -v
Then see in which repository you are in then try git remote set-url --add [Then your repositpory link] git push -u origin master
Yet another reason may be that your entity class has several properties named somhow /.*id/i
- so ending with ID case insensitive AND elementary type AND there is no [Key]
attribute.
EF will namely try to figure out the PK by itself by looking for elementary typed properties ending in ID.
See my case:
public class MyTest, IMustHaveTenant
{
public long Id { get; set; }
public int TenantId { get; set; }
[MaxLength(32)]
public virtual string Signum{ get; set; }
public virtual string ID { get; set; }
public virtual string ID_Other { get; set; }
}
don't ask - lecacy code. The Id
was even inherited, so I could not use [Key]
(just simplifying the code here)
But here EF is totally confused.
What helped was using modelbuilder this in DBContext class.
modelBuilder.Entity<MyTest>(f =>
{
f.HasKey(e => e.Id);
f.HasIndex(e => new { e.TenantId });
f.HasIndex(e => new { e.TenantId, e.ID_Other });
});
the index on PK is implicit.
In my case ; what solved my issue was.....
You may had json like this, the keys without " double quotations....
{ name: "test", phone: "2324234" }
So try any online Json Validator to make sure you have right syntax...
My installer copied a log.txt file which had been generated on an XP computer. I was looking at that log file thinking it was generated on Vista.

Thanks a lot to first answer. Here is modified version to convert a rectangular image into a square one (and rounded) and fill color is being passed as parameter.

int height = 0;
width = inpBitmap.getWidth();
height = inpBitmap.getHeight();
if (width <= height) {
height = width;
} else {
width = height;
}
Bitmap output = Bitmap.createBitmap(width, height, Config.ARGB_8888);
Canvas canvas = new Canvas(output);
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, width, height);
final RectF rectF = new RectF(rect);
final float roundPx = pixels;
paint.setAntiAlias(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(color);

As suggeseted, the way to go is valgrind. It's a profiler that checks many aspects of the running performance of your application, including the usage of memory.
Running your application through Valgrind will allow you to verify if you forget to release memory allocated with malloc, if you free the same memory twice etc.
I'm using the following, though it's hardcoded for gnome-terminal
. It also changes the CWD and buffer for vim to be the same as your current buffer and it's directory.

Just type ctrl+shift+I in google chrome & you will land in an isolated developer window.
Breakpoints and especially conditional breakpoints are your friends.
Also you can write small assert like function which will check values and throw exceptions if needed in debug version of site (some variable is set to true or url has some parameter)
With google-drive-ftp-adapter I have been able to access the My Drive area of Google Drive with the FileZilla FTP client. However, I have not been able to access the Shared with me area.
You can configure which Google account credentials it uses by changing the account property in the configuration.properties file from default to the desired Google account name. See the instructions at http://www.andresoviedo.org/google-drive-ftp-adapter/
I think Dan and Nicola have suitable corrected code, however you may not be clear on why the original code didn't work.
What has been called here a "ternary operator" is called a conditional operator in ECMA-262 section 11.12. It has the form:
LogicalORExpression ? AssignmentExpression : AssignmentExpression
The LogicalORExpression is evaluated and the returned value converted to Boolean (just like an expression in an if condition). If it evaluates to true, then the first AssignmentExpression is evaluated and the returned value returned, otherwise the second is evaluated and returned.
The error in the original code is the extra semi-colons that change the attempted conditional operator into a series of statements with syntax errors.

You can use the onclick
attribute, just return false
if you don't want continue;
<script type="text/javascript">
function confirm_alert(node) {
return confirm("Please click on OK to continue.");
}

<a href="http://www.google.com" onclick="return confirm_alert(this);">Click Me</a>
Try changing the color of your "border-top" attribute to white
This may be due to version incompatibility between your code and the version you have installed.
In my case I was using v8.12.0 for development (locally) and installed latest version v13.7.0 on the server.
So using nvm I switched the node version to v8.12.0 with the below command:
> nvm install 8.12.0 // to install the version I wanted
> nvm use 8.12.0 // use the installed version
NOTE: You need to install nvm on your system to use nvm.
You should try this solution before trying solutions like installing build-essentials or uninstalling the current node version because you could switch between versions easily than reverting all the installations/uninstallations that you've done.
“--single-branch” switch is your answer, but it only works if you have git version 1.8.X onwards, first check
#git --version
If you already have git version 1.8.X installed then simply use "-b branch and --single branch" to clone a single branch
#git clone -b branch --single-branch git://github/repository.git
By default in Ubuntu 12.04/12.10/13.10 and Debian 7 the default git installation is for version 1.7.x only, where --single-branch is an unknown switch. In that case you need to install newer git first from a non-default ppa as below.
sudo add-apt-repository ppa:pdoes/ppa
sudo apt-get update
sudo apt-get install git
git --version
Once 1.8.X is installed now simply do:
git clone -b branch --single-branch git://github/repository.git
Git will now only download a single branch from the server.
IMO, in your case you can try this:
- Map the shared folder to a drive or folder on your machine. (here's how)
- Access the mapped drive/folder as you normally would local files.
Nothing needs to be installed. No services need to be running except those that enable folder sharing.
If you can access the shared folder and maps it on your machine, most things should work just like local files, including command prompts and all explorer-enhancement tools.
This is different from using PsExec (or RDP-ing in) in that you do not need to have administrative rights and/or remote desktop/terminal services connection rights on the remote server, you just need to be able to access those shared folders.
Also make sure you have all the necessary security permissions to run whatever commands/tools you want to run on those shared folders as well.
If, however you wish the processing to be done on the target machine, then you can try PsExec as @divo and @recursive pointed out, something alongs:
PsExec \\yourServerName -u yourUserName cmd.exe
Which will brings gives you a command prompt at the remote machine. And from there you can execute whatever you want.
I am not sure but I think you need either the Server (lanmanserver
) or the Terminal Services (TermService
) service to be running (which should have already be running).
I had issue that starting the service mongodb failed, without logs. what i did to fix the error is to give write access to the directory /var/log/mongodb for user mongodb

Java has a feature called "checked exceptions". That means that there are certain kinds of exceptions, namely those that subclass Exception but not RuntimeException, such that if a method may throw them, it must list them in its throws declaration, say: void readData() throws IOException. IOException is one of those.
Thus, when you are calling a method that lists IOException in its throws declaration, you must either list it in your own throws declaration or catch it.
The rationale for the presence of checked exceptions is that for some kinds of exceptions, you must not ignore the fact that they may happen, because their happening is quite a regular situation, not a program error. So, the compiler helps you not to forget about the possibility of such an exception being raised and requires you to handle it in some way.
However, not all checked exception classes in Java standard library fit under this rationale, but that's a totally different topic.
This thread caught my attention since it deals with a simple problem that requires a lot of work (CPU cycles) even for a modern CPU. And one day I also stood there with the same ¤#%"#" problem. I had to flip millions of bytes. However I know all my target systems are modern Intel-based so let's start optimizing to the extreme!!!
So I used Matt J's lookup code as the base. the system I'm benchmarking on is a i7 haswell 4700eq.
Matt J's lookup bitflipping 400 000 000 bytes: Around 0.272 seconds.
I then went ahead and tried to see if Intel's ISPC compiler could vectorise the arithmetics in the reverse.c.
I'm not going to bore you with my findings here since I tried a lot to help the compiler find stuff, anyhow I ended up with performance of around 0.15 seconds to bitflip 400 000 000 bytes. It's a great reduction but for my application that's still way way too slow..
So people let me present the fastest Intel based bitflipper in the world. Clocked at:

The code takes 32 bytes then masks out the nibbles. The high nibble gets shifted right by 4. Then I use vpshufb and ymm4 / ymm3 as lookup tables. I could use a single lookup table but then I would have to shift left before ORing the nibbles together again.
There are even faster ways of flipping the bits. But I'm bound to single thread and CPU so this was the fastest I could achieve. Can you make a faster version?

This is working fine in firefox at least.
The problem I was facing is, that I got an XML object in stead of a plain text string. Reading an xml-file from my local drive works fine (same directory as the html), so I do not see why reading a text file would be an issue.
I figured that I need to tell jquery to pass a string in stead of an XML object. Which is what I did, and it finally worked:
function readFiles()
{
$.get('file.txt', function(data) {
alert(data);
}, "text");
}
Note the addition of '"text"' at the end. This tells jquery to pass the contents of 'file.txt' as a string in stead of an XML object. The alert box will show the contents of the text file. If you remove the '"text"' at the end, the alert box will say 'XML object'.
I think you want $data[$category] = $question;
Or in case you want an array that maps categories to array of questions:
$data = array();
foreach($file_data as $value) {

$data[$category][] = $question;
}
print_r($data);
Had the same issue. The problem for me was that the height property was also already defined elsewhere, fixed it like this:
.img{
max-width: 100%;
max-height: 100%;
height: inherit !important;
}
I would simply make the assignment happen in the ng-mouseover and ng-mouseleave; no need to bother js file :)
<ul ng-repeat="task in tasks">
<li ng-mouseover="hoverEdit = true" ng-mouseleave="hoverEdit = false">{{task.name}}</li>
<span ng-show="hoverEdit"><a>Edit</a></span>
</ul>
As an alternative you can also query the information_schema
database and retrieve the data from the global_variables
(and global_status
of course too). This approach provides the same information, but gives you the opportunity to do more with the results, as it is a plain old query.
For example you can convert units to become more readable. The following query provides the current global setting for the innodb_log_buffer_size
in bytes and megabytes:
SELECT
variable_name,
variable_value AS innodb_log_buffer_size_bytes,
ROUND(variable_value / (1024*1024)) AS innodb_log_buffer_size_mb
FROM information_schema.global_variables
WHERE variable_name LIKE 'innodb_log_buffer_size';
As a result you get:
+------------------------+------------------------------+---------------------------+
| variable_name | innodb_log_buffer_size_bytes | innodb_log_buffer_size_mb |
+------------------------+------------------------------+---------------------------+
| INNODB_LOG_BUFFER_SIZE | 268435456 | 256 |
+------------------------+------------------------------+---------------------------+

Although there is the RFC 2965 (Set-Cookie2
, had already obsoleted RFC 2109) that should define the cookie nowadays, most browsers don’t fully support that but just comply to the original specification by Netscape.
There is a distinction between the Domain attribute value and the effective domain: the former is taken from the Set-Cookie
header field and the latter is the interpretation of that attribute value. According to the RFC 2965, the following should apply:
.
it will be added by the client).Having the effective domain it must also domain-match the current requested domain for being set; otherwise the cookie will be revised. The same rule applies for choosing the cookies to be sent in a request.
Mapping this knowledge onto your questions, the following should apply:
Domain=.example.com
will be available for www.example.comDomain=.example.com
will be available for example.comDomain=example.com
will be converted to .example.com
and thus will also be available for www.example.comDomain=example.com
will not be available for anotherexample.comAnd to set and read a cookie for/by www.example.com and example.com, set it for .www.example.com
and .example.com
respectively. But the first (.www.example.com
) will only be accessible for other domains below that domain (e.g. foo.www.example.com or bar.www.example.com) where .example.com
can also be accessed by any other domain below example.com (e.g. foo.example.com or bar.example.com).

How are you converting the submitted names to "a simple .txt list"? During that step, can you instead convert them into a simple HTML list or table? Then you could wrap that in a standard header which includes any styling you want.
In the absence of more detailed info:
using(var dbContext = new dbDataContext())
{
var data = dbContext.SomeTable.SingleOrDefault(row => row.id == requiredId);
if(data != null)
{
data.SomeField = newValue;
}
dbContext.SubmitChanges();
}
You ask two questions; your title says "Displaying a vector of strings", but you're not actually doing that, you actually build a single string composed of all the strings and output that.
Your question body asks "Why doesn't this work".
It doesn't work because your for loop is constrained by "userString.size()" which is 0, and you test your loop variable for being "userString.size() - 1". The condition of a for() loop is tested before permitting execution of the first iteration.
int n = 1;
for (int i = 1; i < n; ++i) {
std::cout << i << endl;
}
will print exactly nothing.
So your loop executes exactly no iterations, leaving userString and sentence empty.
Lastly, your code has absolutely zero reason to use a vector. The fact that you used "decltype(userString.size())" instead of "size_t" or "auto", while claiming to be a rookie, suggests you're either reading a book from back to front or you are setting yourself up to fail a class.
So to answer your question at the end of your post: It doesn't work because you didn't step through it with a debugger and inspect the values as it went. While I say it tongue-in-cheek, I'm going to leave it out there.
You can use BOOST_BINARY
while waiting for C++0x. :) BOOST_BINARY
arguably has an advantage over template implementation insofar as it can be used in C programs as well (it is 100% preprocessor-driven.)
To do the converse (i.e. print out a number in binary form), you can use the non-portable itoa
function, or implement your own.
Unfortunately you cannot do base 2 formatting with STL streams (since setbase
will only honour bases 8, 10 and 16), but you can use either a std::string
version of itoa
, or (the more concise, yet marginally less efficient) std::bitset
.
#include <boost/utility/binary.hpp>
#include <stdio.h>
#include <stdlib.h>
#include <bitset>
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
unsigned short b = BOOST_BINARY( 10010 );
char buf[sizeof(b)*8+1];
printf("hex: %04x, dec: %u, oct: %06o, bin: %16s\n", b, b, b, itoa(b, buf, 2));
cout << setfill('0') <<
"hex: " << hex << setw(4) << b << ", " <<
"dec: " << dec << b << ", " <<
"oct: " << oct << setw(6) << b << ", " <<
"bin: " << bitset< 16 >(b) << endl;
return 0;
}
produces:
hex: 0012, dec: 18, oct: 000022, bin: 10010
hex: 0012, dec: 18, oct: 000022, bin: 0000000000010010

In this situation you can use ISNULL() function instead of CASE expression
ISNULL(B.[STAT], C.[EVENT DATE]+10) AS [DATE]
The MySQL daemon should not be executed as the system user root
which (normally) do not has any restrictions.
According to your cli, I suppose you wanted to execute the initscript instead:
sudo /etc/init.d/mysql stop
Another way would be to use the mysqladmin tool (note, root
is the MySQL root user here, not the system root
user):
/usr/local/mysql/bin/mysqladmin --port=8889 -u root shutdown
For hidden files I had to use the following:
DEL /S /Q /A:H Thumbs.db
Your data type is DECIMAL with decimal places, say DECIMAL(10,2). The values in your database are 12, 15, 18, and 20.
12 is the same as 12.0 and 12.00 and 12.000 . It is up to the tool you are using to select the data with, how to display the numbers. Yours either defaults to two digits for decimals or it takes the places from your data definition.
If you only want integers in your column, then change its data type to INT. It makes no sense to use DECIMAL then.
If you want integers and decimals in that column then stay with the DECIMAL type. If you don't like the way you are shown the values, then format them in your application. It's up to that client program to decide for instance if to display point or comma for the decimal separator. (The database can be used from different locations.)
Also don't rely on any database or session settings like a decimal separator being a point and not a comma and then use REPLACE on it. That can work for one person and not for the other.

If the external jar is created by a Maven project only then you can copy the entire project on your system and run a
mvn install
in the project directory. This will add the jar into .m2 directory which is local maven repository.
Now you can add the
<dependency>
<groupId>copy-from-the=maven-pom-of-existing-project</groupId>
<artifactId>copy-from-the=maven-pom-of-existing-project</artifactId>
<version>copy-from-the=maven-pom-of-existing-project</version>
</dependency>
This will ensure that you
mvn exec:java
works. If you use suggested here
<scope>system</scope>
Then you will have to add classes individually while using executing through command line.
You can add the external jars by the following command described here
mvn install:install-file -Dfile=<path-to-file> -DgroupId=<group-id> \
-DartifactId=<artifact-id> -Dversion=<version> -Dpackaging=<packaging>
If you have Adobe Reader

I use this function datetime_to_local_timezone()
, which seems overly convoluted but I found no simpler version of a function that converts a datetime
instance to the local time zone, as configured in the operating system, with the UTC offset that was in effect at that time:
import time, datetime
def datetime_to_local_timezone(dt):
epoch = dt.timestamp() # Get POSIX timestamp of the specified datetime.
st_time = time.localtime(epoch) # Get struct_time for the timestamp. This will be created using the system's locale and it's time zone information.
tz = datetime.timezone(datetime.timedelta(seconds = st_time.tm_gmtoff)) # Create a timezone object with the computed offset in the struct_time.
return dt.astimezone(tz) # Move the datetime instance to the new time zone.
utc = datetime.timezone(datetime.timedelta())
dt1 = datetime.datetime(2009, 7, 10, 18, 44, 59, 193982, utc) # DST was in effect
dt2 = datetime.datetime(2009, 1, 10, 18, 44, 59, 193982, utc) # DST was not in effect
print(dt1)
print(datetime_to_local_timezone(dt1))
print(dt2)
print(datetime_to_local_timezone(dt2))
This example prints four dates. For two moments in time, one in January and one in July 2009, each, it prints the timestamp once in UTC and once in the local time zone. Here, where CET (UTC+01:00) is used in the winter and CEST (UTC+02:00) is used in the summer, it prints the following:
2009-07-10 18:44:59.193982+00:00
2009-07-10 20:44:59.193982+02:00
2009-01-10 18:44:59.193982+00:00
2009-01-10 19:44:59.193982+01:00
Is there any equivalent for the truststore? How can I view the trusted certificates?
Yes there is.The exact same command since keystore and truststore differ only in what they store i.e. private key or signed public key (certificate)
No other difference
Add the below code from the resources tags in your pom.xml inside build tags. so it means resources tags must be inside of build tags in your pom.xml

If I understand your question correctly:
for elem in doc.findall('timeSeries/values/value'):
print elem.get('dateTime'), elem.text
or if you prefer (and if there is only one occurrence of timeSeries/values
:
values = doc.find('timeSeries/values')
for value in values:
print value.get('dateTime'), elem.text
The findall()
method returns a list of all matching elements, whereas find()
returns only the first matching element. The first example loops over all the found elements, the second loops over the child elements of the values
element, in this case leading to the same result.
I don't see where the problem with not finding timeSeries
comes from however. Maybe you just forgot the getroot()
call? (note that you don't really need it because you can work from the elementtree itself too, if you change the path expression to for example /timeSeriesResponse/timeSeries/values
or //timeSeries/values
)
The simpliest way is to drop database phpmyadmin and run sql/create_tables.sql script. Just login to mysql console and:
DROP DATABASE phpmyadmin;
\. {your path to pma}/sql/reate_tables.sql
Worth to mention: Most examples on the net show examples like
git config --global http.proxy proxy_user:proxy_passwd@proxy_ip:proxy_port
So it seems, that - if your proxy needs authentication - you must leave your company-password in the git-config. Which isn't really cool.
But, if you just configure the user without password:
git config --global http.proxy proxy_user@proxy_ip:proxy_port
Git seems (at least on my Windows-machine without credentials-helper) to recognize that and prompts for the proxy-password on repo-access.
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.
Try With Different Logic. You can use bellow code for check all four(4) condition for validation like not null, not blank, not undefined and not zero only use this code (!(!(variable))) in javascript and jquery.
function myFunction() {
var data; //The Values can be like as null, blank, undefined, zero you can test
if(!(!(data)))
{
//If data has valid value
alert("data "+data);
}
else
{
//If data has null, blank, undefined, zero etc.
alert("data is "+data);
}
}
USE .live()
$(selector).live(events, data, handler);
As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers.
$(document).on(events, selector, data, handler);
In addition to @KenM's answer, another important distinction is that, when loading in a saved object, you can assign the contents of an Rds
file. Not so for Rda
> x <- 1:5
> save(x, file="x.Rda")
> saveRDS(x, file="x.Rds")
> rm(x)
## ASSIGN USING readRDS
> new_x1 <- readRDS("x.Rds")
> new_x1
[1] 1 2 3 4 5
## 'ASSIGN' USING load -- note the result
> new_x2 <- load("x.Rda")
loading in to <environment: R_GlobalEnv>
> new_x2
[1] "x"
# NOTE: `load()` simply returns the name of the objects loaded. Not the values.
> x
[1] 1 2 3 4 5
If you want to insert this formula =SUMIFS(B2:B10,A2:A10,F2)
into cell G2, here is how I did it.
Range("G2")="=sumifs(B2:B10,A2:A10," & _
"F2)"
To split a line of code, add an ampersand, space and underscore.
I think the easiest way to do this is to use the Regular Expressions. This way you can get the same split count as you could using myVar.Split('x') but in a multiple character setting.
string myVar = "do this to count the number of words in my wording so that I can word it up!";
int count = Regex.Split(myVar, "word").Length;
First you need to install cors
by using below command :
npm install cors --save
Now add the following code to your app starting file like ( app.js or server.js
)
var express = require('express');
var app = express();
var cors = require('cors');
var bodyParser = require('body-parser');
//enables cors
app.use(cors({
'allowedHeaders': ['sessionId', 'Content-Type'],
'exposedHeaders': ['sessionId'],
'origin': '*',
'methods': 'GET,HEAD,PUT,PATCH,POST,DELETE',
'preflightContinue': false
}));
require('./router/index')(app);
Maybe this helps:
a = [{ 'main_color': 'red', 'second_color':'blue'},
{ 'main_color': 'yellow', 'second_color':'green'},
{ 'main_color': 'yellow', 'second_color':'blue'}]
def in_dictlist((key, value), my_dictlist):
for this in my_dictlist:
if this[key] == value:
return this
return {}
print in_dictlist(('main_color','red'), a)
print in_dictlist(('main_color','pink'), a)

I want to complement polygenelubricants answer:
I personally prefer equals(). But it lake the type compatibility check. Which I think is an important limitation.
To have type compatibility check at compilation time, declare and use a custom function in your enum.
public boolean isEquals(enumVariable) // compare constant from left
public static boolean areEqual(enumVariable, enumVariable2) // compare two variable
With this, you got all the advantage of both solution: NPE protection, easy to read code and type compatibility check at compilation time.
I also recommend to add an UNDEFINED value for enum.
This works in Linux & Windows:
Python 3.x
>>> import sys
>>> print(sys.executable)
C:\path\to\python.exe
Python 2.x
>>> import sys
>>> print sys.executable
/usr/bin/python
Insert mode has no such command, unfortunately. In VIM, to delete the whole word under the cursor you may type viwd
in NORMAL mode. Which means "Visual-block Inner Word Delete". Use an upper case W
to include punctuation.
import * as saveAsFunctions from 'file-saver';

spyOn(saveAsFunctions, 'saveAs').and.callFake(saveAs);
expect(saveAsFunctions.saveAs).toHaveBeenCalled();
})
This worked for me.
Curly braces are always needed for accessing array elements and carrying out brace expansion.
It's good to be not over-cautious and use {}
for shell variable expansion even when there is no scope for ambiguity.
For example:
dir=log
prog=foo
path=/var/${dir}/${prog} # excessive use of {}, not needed since / can't be a part of a shell variable name
logfile=${path}/${prog}.log # same as above, . can't be a part of a shell variable name
path_copy=${path} # {} is totally unnecessary
archive=${logfile}_arch # {} is needed since _ can be a part of shell variable name
So, it is better to write the three lines as:
path=/var/$dir/$prog
logfile=$path/$prog.log
path_copy=$path
which is definitely more readable.
Since a variable name can't start with a digit, shell doesn't need {}
around numbered variables (like $1
, $2
etc.) unless such expansion is followed by a digit. That's too subtle and it does make to explicitly use {}
in such contexts:
set app # set $1 to app
fruit=$1le # sets fruit to apple, but confusing
fruit=${1}le # sets fruit to apple, makes the intention clear
See:
I have created a script used to cut an Apache access.log file several times a day.
So I needed to set a position cursor on last line parsed during last execution.
To this end, I used file.seek()
and file.seek()
methods which allows the storage of the cursor in file.
My code :
ENCODING = "utf8"
CURRENT_FILE_DIR = os.path.dirname(os.path.abspath(__file__))
# This file is used to store the last cursor position
cursor_position = os.path.join(CURRENT_FILE_DIR, "access_cursor_position.log")
# Log file with new lines
log_file_to_cut = os.path.join(CURRENT_FILE_DIR, "access.log")
cut_file = os.path.join(CURRENT_FILE_DIR, "cut_access", "cut.log")
# Set in from_line
from_position = 0
try:
with open(cursor_position, "r", encoding=ENCODING) as f:
from_position = int(f.read())
except Exception as e:
pass
# We read log_file_to_cut to put new lines in cut_file
with open(log_file_to_cut, "r", encoding=ENCODING) as f:
with open(cut_file, "w", encoding=ENCODING) as fw:
# We set cursor to the last position used (during last run of script)
f.seek(from_position)
for line in f:
fw.write("%s" % (line))
# We save the last position of cursor for next usage
with open(cursor_position, "w", encoding=ENCODING) as fw:
fw.write(str(f.tell()))
One correct answer is:
/a/b/*[self::c or self::d or self::e]
Do note that this
a/b/*[local-name()='c' or local-name()='d' or local-name()='e']
is both too-long and incorrect. This XPath expression will select nodes like:
OhMy:c
NotWanted:d
QuiteDifferent:e
str = "[12,23,987,43"
str[0] = ""
You must use a tool called a "header". In a header you declare the function that you want to use. Then you include it in both files. A header is a separate file included using the #include
directive. Then you may call the other function.
void MyFunc();
#include "other.h"
int main() {
MyFunc();
}
#include "other.h"
#include <iostream>
void MyFunc() {
std::cout << "Ohai from another .cpp file!";
std::cin.get();
}
It looks like two of your lines are out of order. You start the process before setting up an event handler to capture the output. It's possible the process is just finishing before the event handler is added.
Switch the lines like so.
p.OutputDataReceived += ...
p.Start();
This script works for me (hat tip to scrappedcola)
var el=document.getElementsByTagName('*');for(var i=0;i<el.length; i++){if (el[i].getAttribute("type")=="text/css") el[i].parentNode.removeChild(el[i]); };
inline style stays intact, though

To directly answer this question's original title "How to delete rows from a pandas DataFrame based on a conditional expression" (which I understand is not necessarily the OP's problem but could help other users coming across this question) one way to do this is to use the drop method:
df = df.drop(some labels)
df = df.drop(df[<some boolean condition>].index)
Example
To remove all rows where column 'score' is < 50:
df = df.drop(df[df.score < 50].index)
In place version (as pointed out in comments)
df.drop(df[df.score < 50].index, inplace=True)
Multiple conditions
(see Boolean Indexing)
The operators are:
|
foror
,&
forand
, and~
fornot
. These must be grouped by using parentheses.
To remove all rows where column 'score' is < 50 and > 20
df = df.drop(df[(df.score < 50) & (df.score > 20)].index)
The key is "the order of the column should be the same"
Example:
create Table A (
A_ID char(3) primary key,
A_name char(10) primary key,
A_desc desc char(50)
)
create Table B (
B_ID char(3) primary key,
B_A_ID char(3),
B_A_Name char(10),
constraint [Fk_B_01] foreign key (B_A_ID,B_A_Name) references A(A_ID,A_Name)
)
the column order on table A should be --> A_ID
then A_Name
; defining the foreign key should follow the same order as well.
I really struggled with this task on the iPad, with text fields showing up invisible in the UITableView, and the whole row turning blue when it gets focus.
What worked for me in the end was the technique described under "The Technique for Static Row Content" in Apple's
Table View Programming Guide. I put both the label and the textField in a UITableViewCell in the NIB for the view, and pull that cell out via an outlet in cellForRowAtIndexPath:
. The resulting code is much neater than UICatalog.
I am using in the way and it is working for me.
public static void main(String[] args) {
new CarpoolDBAppTest();
}
public CarpoolDBAppTest(){
ApplicationContext context = new ClassPathXmlApplicationContext("application-context.xml");
Student stud = (Student) context.getBean("yourBeanId");
}
Here Student is my classm you will get the class matching yourBeanId.
Now work on that object with whatever operation you want to do.

There is really nothing you can do to completely prevent this. Scrapers can fake their user agent, use multiple IP addresses, etc. and appear as a normal user. The only thing you can do is make the text not available at the time the page is loaded - make it with image, flash, or load it with JavaScript. However, the first two are bad ideas, and the last one would be an accessibility issue if JavaScript is not enabled for some of your regular users.
If they are absolutely slamming your site and rifling through all of your pages, you could do some kind of rate limiting.
There is some hope though. Scrapers rely on your site's data being in a consistent format. If you could randomize it somehow it could break their scraper. Things like changing the ID or class names of page elements on each load, etc. But that is a lot of work to do and I'm not sure if it's worth it. And even then, they could probably get around it with enough dedication.
__main__.py
is used for python programs in zip files. The __main__.py
file will be executed when the zip file in run. For example, if the zip file was as such:
test.zip
__main__.py
and the contents of __main__.py
was
import sys
print "hello %s" % sys.argv[1]
Then if we were to run python test.zip world
we would get hello world
out.
So the __main__.py
file run when python is called on a zip file.
Curious, what happens if you use straight net.sockets
instead? Here's some sample code I put together for testing purposes:
var net = require('net');
function HttpRequest(host, port, path, method) {
return {
headers: [],
port: 80,
path: "/",
method: "GET",
socket: null,
_setDefaultHeaders: function() {
this.headers.push(this.method + " " + this.path + " HTTP/1.1");
this.headers.push("Host: " + this.host);
},
SetHeaders: function(headers) {
for (var i = 0; i < headers.length; i++) {
this.headers.push(headers[i]);
}
},
WriteHeaders: function() {
if(this.socket) {
this.socket.write(this.headers.join("\r\n"));
this.socket.write("\r\n\r\n"); // to signal headers are complete
}
},
MakeRequest: function(data) {
if(data) {
this.socket.write(data);
}
this.socket.end();
},
SetupRequest: function() {
this.host = host;
if(path) {
this.path = path;
}
if(port) {
this.port = port;
}
if(method) {
this.method = method;
}
this._setDefaultHeaders();
this.socket = net.createConnection(this.port, this.host);
}
}
};
var request = HttpRequest("www.somesite.com");
request.SetupRequest();
request.socket.setTimeout(30000, function(){
console.error("Connection timed out.");
});
request.socket.on("data", function(data) {
console.log(data.toString('utf8'));
});
request.WriteHeaders();
request.MakeRequest();
M refers to the first non-ambiguous character in "decimal". If you don't add it the number will be treated as a double.
D is double.
Your first bet is to look into Android's native PackageInstaller. I would recommend modifying that app the way you like, or just extract required functionality.
Specifically, if you look into PackageInstallerActivity and its method onClickListener
:
public void onClick(View v) {
if(v == mOk) {
// Start subactivity to actually install the application
Intent newIntent = new Intent();
...
newIntent.setClass(this, InstallAppProgress.class);
...
startActivity(newIntent);
finish();
} else if(v == mCancel) {
// Cancel and finish
finish();
}
}
Then you'll notice that actual installer is located in InstallAppProgress class. Inspecting that class you'll find that initView
is the core installer function, and the final thing it does is call to PackageManager
's installPackage
function:
public void initView() {
...
pm.installPackage(mPackageURI, observer, installFlags, installerPackageName);
}
Next step is to inspect PackageManager, which is abstract class. You'll find installPackage(...)
function there. The bad news is that it's marked with @hide. This means it's not directly available (you won't be able to compile with call to this method).
/**
* @hide
* ....
*/
public abstract void installPackage(Uri packageURI,
IPackageInstallObserver observer,
int flags,String installerPackageName);
But you will be able to access this methods via reflection.
If you are interested in how PackageManager
's installPackage
function is implemented, take a look at PackageManagerService.
You'll need to get package manager object via Context
's getPackageManager()
. Then you will call installPackage
function via reflection.
You can try like below with sqljdbc4-2.0.jar:
public void getConnection() throws ClassNotFoundException, SQLException, IllegalAccessException, InstantiationException {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
String url = "jdbc:sqlserver://<SERVER_IP>:<PORT_NO>;databaseName=" + DATABASE_NAME;
Connection conn = DriverManager.getConnection(url, USERNAME, PASSWORD);
System.out.println("DB Connection started");
Statement sta = conn.createStatement();
String Sql = "select * from TABLE_NAME";
ResultSet rs = sta.executeQuery(Sql);
while (rs.next()) {
System.out.println(rs.getString("COLUMN_NAME"));
}
}
Combining most the answers above into a short snippet:
def top_entries(df):
mat = df.corr().abs()
# Remove duplicate and identity entries
mat.loc[:,:] = np.tril(mat.values, k=-1)
mat = mat[mat>0]
# Unstack, sort ascending, and reset the index, so features are in columns
# instead of indexes (allowing e.g. a pretty print in Jupyter).
# Also rename these it for good measure.
return (mat.unstack()
.sort_values(ascending=False)
.reset_index()
.rename(columns={
"level_0": "feature_a",
"level_1": "feature_b",
0: "correlation"
}))
Are you sure? This forum thread suggests it might be your watch window. Try outputting the string to a MsgBox, which can display a maximum of 1024 characters:
MsgBox RunMacros
To add to the above answers, ensure you define your function like this:
public function functionName(Request $request) {
//
}
Note the "(Request $request)", now set a session like this:
$request->session()->put('key', 'value');
And retrieve the session in this way:
$data = $request->session()->get('key');
To erase the session try this:
$request->session()->forget('key');
or
$request->session()->flush();

Add a little Color to your Console Text
HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
// you can loop k higher to see more color choices
for(int k = 1; k < 255; k++)
{
// pick the colorattribute k you want
SetConsoleTextAttribute(hConsole, k);
cout << k << " I want to be nice today!" << endl;
}
Character Attributes Here is how the "k" value be interpreted.
// Store integer 182
int decValue = 182;
// Convert integer 182 as a hex in a string variable
string hexValue = decValue.ToString("X");
// Convert the hex string back to the number
int decAgain = int.Parse(hexValue, System.Globalization.NumberStyles.HexNumber);
This will force the DefaultWebProxy
to use default credentials, similar effect as done through UseDefaultCredentials = true
.
WebRequest.DefaultWebProxy.Credentials = CredentialCache.DefaultNetworkCredentials;
Hence all newly created WebRequest
instances will use default proxy which has been configured to use proxy's default credentials.
