Issue no 2.
Your local server has two database server and those database server conflict. this conflict like this mysql server & xampp or lampp or wamp server. Please one of the database like mysql server because xampp or lampp server automatically install mysql server on this machine
I managed to fix it finally. The problem is not related to HikariCP.
The problem persisted because of some complex methods in REST controllers executing multiple changes in DB through JPA repositories. For some reasons calls to these interfaces resulted in a growing number of "freezed" active connections, exhausting the pool. Either annotating these methods as @Transactional
or enveloping all the logic in a single call to transactional service method seem to solve the problem.
Please note instead of
public TomcatEmbeddedServletContainerFactory tomcatFactory()
I had to use the following method signature
public EmbeddedServletContainerFactory embeddedServletContainerFactory()
you put resource-ref in the description tag in web.xml
You may have more than one org.springframework.beans.factory.config.PropertyPlaceholderConfigurer
in your application. Try setting a breakpoint on the setLocations
method of the superclass and see if it's called more than once at application startup. If there is more than one org.springframework.beans.factory.config.PropertyPlaceholderConfigurer
, you might need to look at configuring the ignoreUnresolvablePlaceholders
property so that your application will start up cleanly.
I found the solution to this problem here: http://www.hildeberto.com/2008/05/hibernate-and-jersey-conflict-on.html
This warning is about unsafe use of strcpy. Try IOBname[ii]='\0';

Is there a built-in function to print all the current properties and values of an object?
No. The most upvoted answer excludes some kinds of attributes, and the accepted answer shows how to get all attributes, including methods and parts of the non-public api. But there is no good complete builtin function for this.
So the short corollary is that you can write your own, but it will calculate properties and other calculated data-descriptors that are part of the public API, and you might not want that:
from pprint import pprint
from inspect import getmembers
from types import FunctionType
def attributes(obj):
disallowed_names = {
name for name, value in getmembers(type(obj))
if isinstance(value, FunctionType)}
return {
name: getattr(obj, name) for name in dir(obj)
if name[0] != '_' and name not in disallowed_names and hasattr(obj, name)}
def print_attributes(obj):
pprint(attributes(obj))
Observe the application of the currently top voted answer on a class with a lot of different kinds of data members:
from pprint import pprint
class Obj:
__slots__ = 'foo', 'bar', '__dict__'
def __init__(self, baz):
self.foo = ''
self.bar = 0
self.baz = baz
@property
def quux(self):
return self.foo * self.bar
obj = Obj('baz')
pprint(vars(obj))
only prints:
{'baz': 'baz'}
Because vars
only returns the __dict__
of an object, and it's not a copy, so if you modify the dict returned by vars, you're also modifying the __dict__
of the object itself.
vars(obj)['quux'] = 'WHAT?!'
vars(obj)
returns:
{'baz': 'baz', 'quux': 'WHAT?!'}
-- which is bad because quux is a property that we shouldn't be setting and shouldn't be in the namespace...
Applying the advice in the currently accepted answer (and others) is not much better:
>>> dir(obj)
['__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__slots__', '__str__', '__subclasshook__', 'bar', 'baz', 'foo', 'quux']
As we can see, dir
only returns all (actually just most) of the names associated with an object.
inspect.getmembers
, mentioned in the comments, is similarly flawed - it returns all names and values.
When teaching I have my students create a function that provides the semantically public API of an object:
def api(obj):
return [name for name in dir(obj) if name[0] != '_']
We can extend this to provide a copy of the semantic namespace of an object, but we need to exclude __slots__
that aren't assigned, and if we're taking the request for "current properties" seriously, we need to exclude calculated properties (as they could become expensive, and could be interpreted as not "current"):
from types import FunctionType
from inspect import getmembers
def attrs(obj):
disallowed_properties = {
name for name, value in getmembers(type(obj))
if isinstance(value, (property, FunctionType))}
return {
name: getattr(obj, name) for name in api(obj)
if name not in disallowed_properties and hasattr(obj, name)}
And now we do not calculate or show the property, quux:
>>> attrs(obj)
{'bar': 0, 'baz': 'baz', 'foo': ''}
But perhaps we do know our properties aren't expensive. We may want to alter the logic to include them as well. And perhaps we want to exclude other custom data descriptors instead.
Then we need to further customize this function. And so it makes sense that we cannot have a built-in function that magically knows exactly what we want and provides it. This is functionality we need to create ourselves.
There is no built-in function that does this, and you should do what is most semantically appropriate for your situation.
in the java src you can add a new tool like this:
public static String remplaceVirguleParpoint(String chaine) {
return chaine.replaceAll(",", "\\.");
}
..these three svn CLI commands in this sequence while cd-ed into the correct directory worked for me.
edit2, I figured out a new solution without the need of setting index
newdf=pd.concat([df1,df2]).drop_duplicates(keep=False)
Okay i found the answer of highest vote already contain what I have figured out. Yes, we can only use this code on condition that there are no duplicates in each two dfs.
I have a tricky method. First we set ’Name’ as the index of two dataframe given by the question. Since we have same ’Name’ in two dfs, we can just drop the ’smaller’ df’s index from the ‘bigger’ df. Here is the code.
df1.set_index('Name',inplace=True)
df2.set_index('Name',inplace=True)
newdf=df1.drop(df2.index)
private void button1_Click(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection();
con.ConnectionString = "data source=CHANCHAL\SQLEXPRESS;initial catalog=AssetManager;user id=GIPL-PC\GIPL;password=";
con.Open();
SqlDataAdapter ad = new SqlDataAdapter("select * from detail1", con);
SqlCommandBuilder cmdbl = new SqlCommandBuilder(ad);
DataSet ds = new DataSet("detail1");
ad.Fill(ds, "detail1");
DataRow row = ds.Tables["detail1"].NewRow();
row["Name"] = textBox1.Text;
row["address"] =textBox2.Text;
ds.Tables["detail1"].Rows.Add(row);
ad.Update(ds, "detail1");
con.Close();
MessageBox.Show("insert secussfully");
}
I had to add parseInt()
to tell v-for it was looking at a number.
<li v-for="n in parseInt(count)" :key="n">{{n}}</li>
ps is the most reliable method. The SHELL environment variable is not guaranteed to be set and even if it is, it can be easily spoofed.

Implicit vs explicit is still a problem, but once dust settles, renaming of attributes/variables to start with ci (and a big fat doc comment explaining that ci stands for case insensitive) I think is a perfect solution - as readers of the code must be fully aware that we are dealing with case insensitive underlying data structures. This will hopefully fix some hard to reproduce bugs, which I suspect boil down to case sensitivity.
Comments/corrections welcome :)
I answer my own question reporting what therefore seems to be the most comprehensive overall procedure to Access IP Camera in Python OpenCV.
Given an IP camera:
IP
address port
where the IP address is accessed protocol
(HTTP/RTSP etc.) specified by the camera provider Then, if your camera is protected go ahead and find out:
username
password
Then use your data to run the following script:
"""Access IP Camera in Python OpenCV"""
import cv2
stream = cv2.VideoCapture('protocol://IP:port/1')
# Use the next line if your camera has a username and password
# stream = cv2.VideoCapture('protocol://username:password@IP:port/1')
while True:
r, f = stream.read()
cv2.imshow('IP Camera stream',f)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cv2.destroyAllWindows()
NOTE: In my original question I specify to being working with Teledyne Dalsa Genie Nano XL Camera. Unfortunately for this kind of cameras this normal way of accessing the IP Camera video stream does not work and the Sapera SDK must be employed in order to grab frames from the device.
From what suggest others and from pathlib documentation, a simple and clear solution is the following (suppose the file we need to refer to: Test/data/users.csv
:
# This file location: Tests/src/long/module/subdir/some_script.py
from pathlib import Path
# back to Tests/
PROJECT_ROOT = Path(__file__).parents[4]
# then down to Test/data/users.csv
CSV_USERS_PATH = PROJECT_ROOT / 'data' / 'users.csv'
with CSV_USERS_PATH.open() as users:
print(users.read())
Now this looks a bit odd to me, because if you move some_script.py
around, the path to the root of our project may change (we would need to modify parents[4]
). On the other hand I found a solution that I prefer based on the same idea.
Suppose we have the following directory structure:
Tests
+-- data
¦ +-- users.csv
+-- src
+-- long
¦ +-- module
¦ +-- subdir
¦ +-- some_script.py
+-- main.py
+-- paths.py
The paths.py
file will be responsible for storing the root location of our projet:
from pathlib import Path
PROJECT_ROOT = Path(__file__).parents[1]
All scripts can now use paths.PROJECT_ROOT
to express absolute paths from the root of the project. For example in src/long/module/subdir/some_script.py
we could have:
from paths import PROJECT_ROOT
CSV_USERS_PATH = PROJECT_ROOT / 'data' / 'users.csv'
def hello():
with CSV_USERS_PATH.open() as f:
print(f.read())
And everything goes as expected:
~/Tests/src/$ python main.py
/Users/cglacet/Tests/data/users.csv
hello, user
~/Tests/$ python src/main.py
/Users/cglacet/Tests/data/users.csv
hello, user
The main.py
script simply is:
from long.module.subdir import some_script
some_script.hello()
You have to use the SSH version, not HTTPS. When you clone from a repository, copy the link with the SSH version, because SSH is easy to use and solves all problems with access. You can set the access for every SSH you input into your account (like push, pull, clone, etc...)

I just found this post: http://forum.springsource.org/showthread.php?68949-White-spaces-are-required-between-publicId-and-systemId./page2&s=c69fe19798f5a071d22eaf681ca84a56
A couple people here had success by switching the lines around in an XML file.
Try this:
delete from your_table;
delete from sqlite_sequence where name='your_table';
SQLite keeps track of the largest ROWID that a table has ever held using the special
SQLITE_SEQUENCE
table. TheSQLITE_SEQUENCE
table is created and initialized automatically whenever a normal table that contains an AUTOINCREMENT column is created. The content of the SQLITE_SEQUENCE table can be modified using ordinary UPDATE, INSERT, and DELETE statements. But making modifications to this table will likely perturb the AUTOINCREMENT key generation algorithm. Make sure you know what you are doing before you undertake such changes.
How can it ever be longer than
tmp = my_list[indexOfPwd2]
my_list[indexOfPwd2] = my_list[indexOfPwd2 + 1]
my_list[indexOfPwd2 + 1] = tmp
That's just a plain swap using temporary storage.

You could call LockFile via interop on the region of file you are interested in. This will not throw an exception, if it succeeds you will have a lock on that portion of the file (which is held by your process), that lock will be held until you call UnlockFile or your process dies.
You can just simply add the following code;

ToolTip1.SetToolTip( Label1, "Label for Label1");
one simple way is to use trim option with publitio url-based api.
once you get your video uploaded, just set start offset and end offset in url (so_2,eo_2) like so:
https://media.publit.io/file/so_2,eo_2/tummy.mp4
this will create instantly new videos starting from 2nd second and 2 seconds in length. you can split videos this way anyway you like.
For small numbers n%3 == 0
will be fine. For very large numbers I propose to calculate the cross sum first and then check if the cross sum is a multiple of 3:
def is_divisible_by_3(number):
if sum(map(int, str(number))) % 3 != 0:
my_bool = False
return my_bool
Here is what i did and it works.
I just used a stringified object.

if i wanted to sort by text i would do

Have faced the similar issue, resolved this by right clicking on the main method in the outline view and run as Java application.
For AF_UNIX you can use call unlink (path); after close() socket in "server" app
We were also facing this issue when using IE version 11 to access our React app (create-react-app with react version 16.0.0 with jQuery v3.1.1) on the enterprise intranet. To solve it, i simply followed the directions at this url which are also listed below:
Make sure to set the DOCTYPE to standards mode by making sure the first line of the master file is: <!DOCTYPE html>
Force IE 11 to use the latest internal version by including the following meta tag in the head tag: <meta http-equiv="X-UA-Compatible" content="IE=edge;" />
NOTE: I did not face the problem when using IE to access the app in development mode on my local machine (localhost:3000). The problem occurred only when accessing the app deployed to the DEV server on the company Intranet, probably because of some company wide Windows OS policy settings and/or IE Internet Options.

The toggle tells Bootstrap what to do and the target tells Bootstrap which element is going to open. So whenever a link like that is clicked, a modal with an id of “basicModal” will appear.
Excerpt from PostgreSQL documentation:
Restricting and cascading deletes are the two most common options. [...]
CASCADE
specifies that when a referenced row is deleted, row(s) referencing it should be automatically deleted as well.
This means that if you delete a category – referenced by books – the referencing book will also be deleted by ON DELETE CASCADE
.
Example:
CREATE SCHEMA shire;
CREATE TABLE shire.clans (
id serial PRIMARY KEY,
clan varchar
);
CREATE TABLE shire.hobbits (
id serial PRIMARY KEY,
hobbit varchar,
clan_id integer REFERENCES shire.clans (id) ON DELETE CASCADE
);
DELETE FROM
clans will CASCADE
to hobbits by REFERENCES
.
sauron@mordor> psql
sauron=# SELECT * FROM shire.clans;
id | clan
----+------------

2 | Gamgi
(2 rows)
sauron=# SELECT * FROM shire.hobbits;
id | hobbit | clan_id
----+----------+---------

3 | Samwise | 2
(3 rows)
sauron=# DELETE FROM shire.clans WHERE id = 1 RETURNING *;

You want to use the decimal module but you also need to specify the rounding mode. Here's an example:
>>> import decimal
>>> decimal.Decimal('8.333333').quantize(decimal.Decimal('.01'), rounding=decimal.ROUND_UP)
Decimal('8.34')
>>> decimal.Decimal('8.333333').quantize(decimal.Decimal('.01'), rounding=decimal.ROUND_DOWN)
Decimal('8.33')

Running the apc.php script is key to understanding what your problem is, IMO. This helped us size our cache properly and for the moment, seems to have resolved the problem.
All right, so i'm a serious cryptkeeper here by dragging up this very old question, but there is a much simpler approach to this, which was touched on by @Baserz above. And that is to use a combination of C# Extension methods and caching (Do NOT use session).
In fact, Microsoft has already provided a number of such extensions in the Microsoft.AspNet.Identity.IdentityExtensions
namespace. For instance, GetUserId()
is an extension method that returns the user Id. There is also GetUserName()
and FindFirstValue()
, which returns claims based on the IPrincipal.
So you need only include the namespace, and then call User.Identity.GetUserName()
to get the users name as configured by ASP.NET Identity.
I'm not certain if this is cached, since the older ASP.NET Identity is not open sourced, and I haven't bothered to reverse engineer it. However, if it's not then you can write your own extension method, that will cache this result for a specific amount of time.
When I develop, it's on a different domain within a folder. When I take a site live, that folder doesn't exist anymore. Using RewriteBase allows me to use the same .htaccess file in both environments.

When developing:
# RewriteBase /
RewriteBase /dev_folder/
in VB 2008 (VB 9.0) and later, prefix Right() as Microsoft.VisualBasic.Right(string, number of characters)
Dim str as String = "Hello World"
Msgbox(Microsoft.VisualBasic.Right(str,5))

Same goes for Left() too.
tooltips: {

}
I have never seen it done that way in JavaScript. If you want a function with optional parameters that get assigned default values if the parameters are omitted, here's a way to do it:
function(a, b) {
if (typeof a == "undefined") {
a = 10;
}
if (typeof b == "undefined") {
a = 20;
}
alert("a: " + a + " b: " + b);
}
If you want to guard against non-terminated strings, which can cause all sorts of problems, copy your string like this:
char array1[18] = {"abcdefg"};
char array2[18];
size_t destination_size = sizeof (array2);
strncpy(array2, array1, destination_size);
array2[destination_size - 1] = '\0';
That last line is actually important, because strncpy()
does not always null terminate strings. (If the destination buffer is too small to contain the whole source string, sntrcpy() will not null terminate the destination string.)
The manpage for strncpy() even states "Warning: If there is no null byte among the first n bytes of src, the string placed in dest will not be null-terminated."
The reason strncpy() behaves this somewhat odd way, is because it was not actually originally intended as a safe way to copy strings.
Another way is to use snprintf() as a safe replacement for strcpy():
snprintf(array2, destination_size, "%s", array1);
(Thanks jxh for the tip.)
If you need use it in the code.
Gson gsone = new Gson();
JsonObject res = gsone.toJsonTree(sqlParams).getAsJsonObject();
in C++11 you may use Copy()
that works for std containers
template <typename Container1, typename Container2>
auto Copy(Container1& c1, Container2& c2)
-> decltype(c2.begin())
{
auto it1 = std::begin(c1);
auto it2 = std::begin(c2);
while (it1 != std::end(c1)) {
*it2++ = *it1++;
}
return it2;
}
I guess there is a simple solution which I recently used after going through so many answers here.
with open(file_name) as f_in:

There are two main approaches for serializing and restoring a model.
The first (recommended) saves and loads only the model parameters:
torch.save(the_model.state_dict(), PATH)
Then later:
the_model = TheModelClass(*args, **kwargs)
the_model.load_state_dict(torch.load(PATH))
The second saves and loads the entire model:
torch.save(the_model, PATH)
Then later:
the_model = torch.load(PATH)
However in this case, the serialized data is bound to the specific classes and the exact directory structure used, so it can break in various ways when used in other projects, or after some serious refactors.
public string GetDomainName<T>()
{
var dnAttribute = typeof(T).GetCustomAttributes(
typeof(DomainNameAttribute), true
).FirstOrDefault() as DomainNameAttribute;
if (dnAttribute != null)
{
return dnAttribute.Name;
}
return null;
}
UPDATE:
This method could be further generalized to work with any attribute:
public static class AttributeExtensions
{
public static TValue GetAttributeValue<TAttribute, TValue>(
this Type type,
Func<TAttribute, TValue> valueSelector)
where TAttribute : Attribute
{
var att = type.GetCustomAttributes(
typeof(TAttribute), true
).FirstOrDefault() as TAttribute;
if (att != null)
{
return valueSelector(att);
}
return default(TValue);
}
}
and use like this:
string name = typeof(MyClass)
.GetAttributeValue((DomainNameAttribute dna) => dna.Name);
To get a deterministic value for the day of week for a given date you could use a combination of DATEPART() and @@datefirst. Otherwise your dependent on the settings on the server.
Check out the following site for a better solution: MS SQL: Day of Week
The day of week will then be in the range 0 to 6, where 0 is Sunday, 1 is Monday, etc. Then you can use a simple case statement to return the correct weekday name.

When programming the NODEMCU card with the Arduino IDE, you need to customize it and you must have selected the correct card.
Open Arduino IDE and go to files and click on the preference in the Arduino IDE.
Add the following link to the Additional Manager URLS section: "http://arduino.esp8266.com/stable/package_esp8266com_index.json" and press the OK button.
Then click Tools> Board Manager. Type "ESP8266" in the text box to search and install the ESP8266 software for Arduino IDE.
You will be successful when you try to program again by selecting the NodeMCU card after these operations. I hope I could help.
Just use the select query to display the table varialble, where ever you want to check.

From practical standpoint just one minor digression:
import torch
dev = torch.device("cuda") if torch.cuda.is_available() else torch.device("cpu")
This dev
now knows if cuda or cpu.
And there is a difference how you deal with model and with tensors when moving to cuda. It is a bit strange at first.
import torch
import torch.nn as nn
dev = torch.device("cuda") if torch.cuda.is_available() else torch.device("cpu")
t1 = torch.randn(1,2)
t2 = torch.randn(1,2).to(dev)
print(t1) # tensor([[-0.2678, 1.9252]])
print(t2) # tensor([[ 0.5117, -3.6247]], device='cuda:0')
t1.to(dev)
print(t1) # tensor([[-0.2678, 1.9252]])
print(t1.is_cuda) # False
t1 = t1.to(dev)
print(t1) # tensor([[-0.2678, 1.9252]], device='cuda:0')
print(t1.is_cuda) # True
class M(nn.Module):
def __init__(self):
super().__init__()
self.l1 = nn.Linear(1,2)
def forward(self, x):
x = self.l1(x)
return x
model = M() # not on cuda
model.to(dev) # is on cuda (all parameters)
print(next(model.parameters()).is_cuda) # True
This all is tricky and understanding it once, helps you to deal fast with less debugging.
If there are multiple commits, you can use git rebase -i
to squash two commits into one.
If there are only two commits you want to merge, and they are the "most recent two", the following commands can be used to combine the two commits into one:
git reset --soft "HEAD^"
git commit --amend
I think the biggest confusion is that xml namespace is pointing to some kind of URL that doesn't have any information. But the truth is that the person who invented below namespace:
xmlns:android="http://schemas.android.com/apk/res/android"
could also call it like that:
xmlns:android="asjkl;fhgaslifujhaslkfjhliuqwhrqwjlrknqwljk.rho;il"
This is just a unique identifier. However it is established that you should put there URL that is unique and can potentially point to the specification of used tags/attributes in that namespace. It's not required tho.
Why it should be unique? Because namespaces purpose is to have them unique so the attribute for example called background from your namespace can be distinguished from the background from another namespace.
Because of that uniqueness you do not need to worry that if you create your custom attribute you gonna have name collision.
Uhm, you are describing dict1 == dict2
( check if boths dicts are equal )
But what your code does is all( dict1[k]==dict2[k] for k in dict1 )
( check if all entries in dict1 are equal to those in dict2 )
You can also use this, I hope you can serve them.

FileZilla does not have any command line arguments (nor any other way) that allow an automatic transfer.
Some references:
Though you can use any other client that allows automation.
You have not specified, what protocol you are using. FTP or SFTP? You will definitely be able to use WinSCP, as it supports all protocols that FileZilla does (and more).
Combine WinSCP scripting capabilities with Windows Scheduler:
A typical WinSCP script for upload (with SFTP) looks like:
open sftp://user:[email protected]/ -hostkey="ssh-rsa 2048 xxxxxxxxxxx...="
put c:\mypdfs\*.pdf /home/user/
close
With FTP, just replace the sftp://
with the ftp://
and remove the -hostkey="..."
switch.
Similarly for download: How to schedule an automatic FTP download on Windows?
WinSCP can even generate a script from an imported FileZilla session.
For details, see the guide to FileZilla automation.
(I'm the author of WinSCP)
Another option, if you are using SFTP, is the psftp.exe
client from PuTTY suite.
Represent it as a text entity (ASCII 39):
<input type='text' id='abc' value='hel'lo'>
Try this,
# typically, os.path.join(os.path.dirname(__file__), 'media')
MEDIA_ROOT = '<your_path>/media'
MEDIA_URL = '/media/'
urlpatterns = patterns('',
(r'^media/(?P<path>.*)$', 'django.views.static.serve',
{'document_root': settings.MEDIA_ROOT}),
)
<img src="{{ MEDIA_URL }}<sub-dir-under-media-if-any>/<image-name.ext>" />
Beware! using Context()
will yield you an empty value for {{MEDIA_URL}}
. You must use RequestContext()
, instead.
I hope, this will help.
This is a pretty good source for info about Haskell and its uses:
You can require JSON files as of Node v0.5.x (referencing this answer)
config.json:
{
"username" : "root",
"password" : "foot"
}
app.js:
var config = require('./config.json');
log_in(config.username, config.password);
If your object looks like this:
obj = {
"_id":"5078c3a803ff4197dc81fbfb",
"email":"[email protected]",
"image":"some_image_url",
"name":"Name 1"
}
Probably the simplest method in JavaScript is:
obj.id = obj._id
del object['_id']
As a result, you will get:
obj = {
"id":"5078c3a803ff4197dc81fbfb",
"email":"[email protected]",
"image":"some_image_url",
"name":"Name 1"
}
IF you have excel 2007, you can use

Because there was a big change in 2010 about excel's function
util.print can be used also. Read: http://nodejs.org/api/util.html#util_util_print
util.print([...])# A synchronous output function. Will block the process, cast each argument to a string then output to stdout. Does not place newlines after each argument.
An example:
// get total length
var len = parseInt(response.headers['content-length'], 10);
var cur = 0;
// handle the response
response.on('data', function(chunk) {
cur += chunk.length;
util.print("Downloading " + (100.0 * cur / len).toFixed(2) + "% " + cur + " bytes\r");
});
For one matched character replace, use str_replace:
$string = str_replace(' ', '_', $string);
For all matched character replace, use preg_replace:
$string = preg_replace('/\s+/', '_', $string);
My solution is quite simple, i faced the same problem
Fatal error in launcher: Unable to create process using '"'
the solution was to change the path from where i am running pip.
There is no semicolon at the end of that instruction causing the error.
EDIT
Like RiverC pointed out, there is no semicolon at the end of the previous line!
require ("scripts/connect.php")
EDIT
It seems you have no-semicolons whatsoever.
http://php.net/manual/en/language.basic-syntax.instruction-separation.php
As in C or Perl, PHP requires instructions to be terminated with a semicolon at the end of each statement.

Is "Id" indexed? If not, that's an important thing to do (I suspect it is already indexed).
Also, do you need to return ALL columns? You may be able to get a substantial improvement in speed if you only actually need a smaller subset of columns which can be FULLY catered for by the index on the ID column - e.g. if you have a NONCLUSTERED index on the Id column, with no other fields included in the index, then it would have to do a lookup on the clustered index to actually get the rest of the columns to return and that could be making up a lot of the cost of the query. If it's a CLUSTERED index, or a NONCLUSTERED index that includes all the other fields you want to return in the query, then you should be fine.
Or if none of the above works, type out the name of the outlet into the file first @IBOutlet weak var headerHeightConstraint: NSLayoutConstraint!
and then click and drag from the outlet in the nib to the variable you just programmatically created. It should work without any of the hassle of cleaning, building, and deleting anything.
The auto keyword is simply asking the compiler to deduce the type of the variable from the initialization.
Even a pre-C++0x compiler knows what the type of an (initialization) expression is, and more often than not, you can see that type in error messages.
#include <vector>
#include <iostream>
using namespace std;
int main()
{
vector<int>s;
s.push_back(11);
s.push_back(22);
s.push_back(33);
s.push_back(55);
for (int it=s.begin();it!=s.end();it++){
cout<<*it<<endl;
}
}
Line 12: error: cannot convert '__gnu_debug::_Safe_iterator<__gnu_cxx::__normal_iterator<int*, __gnu_norm::vector<int, std::allocator<int> > >, __gnu_debug_def::vector<int, std::allocator<int> > >' to 'int' in initialization
The auto keyword simply allows you to take advantage of this knowledge - if you (compiler) know the right type, just choose for me!
You need to use the DataGridViewColumn.AutoSizeMode
property.
You can use one of these values for column 0 and 1:
AllCells: The column width adjusts to fit the contents of all cells in the column, including the header cell.
AllCellsExceptHeader: The column width adjusts to fit the contents of all cells in the column, excluding the header cell.
DisplayedCells: The column width adjusts to fit the contents of all cells in the column that are in rows currently displayed onscreen, including the header cell.
DisplayedCellsExceptHeader: The column width adjusts to fit the contents of all cells in the column that are in rows currently displayed onscreen, excluding the header cell.
Then you use the Fill value for column 2
The column width adjusts so that the widths of all columns exactly fills the display area of the control...
this.DataGridView1.Columns[0].AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
this.DataGridView1.Columns[1].AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
this.DataGridView1.Columns[2].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;
As pointed out by other users, the default value can be set at datagridview
level with DataGridView.AutoSizeColumnsMode
property.
this.DataGridView1.Columns[0].AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
this.DataGridView1.Columns[1].AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
could be:
this.DataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.DisplayedCells;
Important note:
If your grid is bound to a datasource and columns are auto-generated (AutoGenerateColumns
property set to True), you need to use the DataBindingComplete
event to apply style AFTER columns have been created.
In some scenarios (change cells value by code for example), I had to call DataGridView1.AutoResizeColumns();
to refresh the grid.
Can also invoke oShell.Exec in order to be able to read STDIN/STDOUT/STDERR responses. Perfect for error checking which it seems you're doing with your sanity .BAT.
As I understand Copy-Item -Exclude
then you are doing it correct. What I usually do, get 1'st, and then do after, so what about using Get-Item
as in
Get-Item -Path $copyAdmin -Exclude $exclude |
Copy-Item -Path $copyAdmin -Destination $AdminPath -Recurse -force
The ConverterParameter
property can not be bound because it is not a dependency property.
Since Binding
is not derived from DependencyObject
none of its properties can be dependency properties. As a consequence, a Binding can never be the target object of another Binding.
There is however an alternative solution. You could use a MultiBinding
with a multi-value converter instead of a normal Binding:
<Style TargetType="FrameworkElement">
<Setter Property="Visibility">
<Setter.Value>
<MultiBinding Converter="{StaticResource AccessLevelToVisibilityConverter}">
<Binding Path="Tag" RelativeSource="{RelativeSource Mode=FindAncestor,
AncestorType=UserControl}"/>
<Binding Path="Tag" RelativeSource="{RelativeSource Mode=Self}"/>
</MultiBinding>
</Setter.Value>
</Setter>
</Style>
The multi-value converter gets an array of source values as input:
public class AccessLevelToVisibilityConverter : IMultiValueConverter
{
public object Convert(
object[] values, Type targetType, object parameter, CultureInfo culture)
{
return values.All(v => (v is bool && (bool)v))
? Visibility.Visible
: Visibility.Hidden;
}
public object[] ConvertBack(
object value, Type[] targetTypes, object parameter, CultureInfo culture)
{
throw new NotSupportedException();
}
}
You should use some form of the String#equals(Object)
method. However, there is some subtlety in how you should do it:
If you have a string literal then you should use it like this:
"Hello".equals(someString);
This is because the string literal "Hello"
can never be null, so you will never run into a NullPointerException
.
If you have a string and another object then you should use:
myString.equals(myObject);
You can make sure you are actually getting string equality by doing this. For all you know, myObject
could be of a class that always returns true
in its equals
method!
Start with the object less likely to be null because this:
String foo = null;
String bar = "hello";
foo.equals(bar);
will throw a NullPointerException
, but this:
String foo = null;
String bar = "hello";
bar.equals(foo);
will not. String#equals(Object)
will correctly handle the case when its parameter is null, so you only need to worry about the object you are dereferencing--the first object.
Since getText()
is non-static you cannot call it from a static method.
To understand why, you have to understand the difference between the two.
Instance (non-static) methods work on objects that are of a particular type (the class). These are created with the new like this:
SomeClass myObject = new SomeClass();
To call an instance method, you call it on the instance (myObject
):
myObject.getText(...)
However a static method/field can be called only on the type directly, say like this:
The previous statement is not correct. One can also refer to static fields with an object reference like myObject.staticMethod()
but this is discouraged because it does not make it clear that they are class variables.
... = SomeClass.final
And the two cannot work together as they operate on different data spaces (instance data and class data)
Let me try and explain. Consider this class (psuedocode):
class Test {
string somedata = "99";
string getText() { return somedata; }
static string TTT = "0";
}
Now I have the following use case:
Test item1 = new Test();
item1.somedata = "200";
Test item2 = new Test();
Test.TTT = "1";
What are the values?
Well
in item1 TTT = 1 and somedata = 200
in item2 TTT = 1 and somedata = 99
In other words, TTT
is a datum that is shared by all the instances of the type. So it make no sense to say
class Test {
string somedata = "99";
string getText() { return somedata; }
static string TTT = getText(); // error there is is no somedata at this point
}
So the question is why is TTT static or why is getText() not static?
Remove the static
and it should get past this error - but without understanding what your type does it's only a sticking plaster till the next error. What are the requirements of getText()
that require it to be non-static?
I had the same issue using Windows, got if fixed by opening it in Notepad++ and changing the encoding from "UCS-2 LE BOM" to "UTF-8".
I came up with the same problem and I'm sharing how I fixed it. It may help some people.
First, check your Android version. If it is running on Android 6.0 and higher (API level 23+), then you need to :
**<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />**
<application ...>
...
</application>
Then, request that the user approve each permission at runtime
if (ContextCompat.checkSelfPermission(thisActivity, Manifest.permission.CAMERA)
!= PackageManager.PERMISSION_GRANTED) {
// here, Permission is not granted
ActivityCompat.requestPermissions(this, new String[] {android.Manifest.permission.CAMERA}, 50);
}
For more information, have a look at the API documentation here
The problem with all presented answers it complete lack of taking triggers (and probably other side effects) into account. Solution like
INSERT OR IGNORE ...
UPDATE ...
leads to both triggers executed (for insert and then for update) when row does not exist.
Proper solution is
UPDATE OR IGNORE ...
INSERT OR IGNORE ...
in that case only one statement is executed (when row exists or not).
I have done some analysis about this issue on four popular browser versions.
the answer I found is to implement this on keyup in conjunction with the style tag.
<-- form name="frmTest" -->
<-- input type="text" size=100 class="ucasetext" name="textBoxUCase" id="textBoxUCase" -->
<-- /form -->
window.onload = function() {
var input = document.frmTest.textBoxUCase;
input.onkeyup = function() {
input.value = input.value.toUpperCase();
}
};

Don't worry just change the

to previous version. It worked for me hope it works for you too. Happy coding.
This is an old question, but I thought I'd put in my C# 6 answer. I often have to set up test data that is easily entered in-code as a list of tuples. With a couple of extension functions, it is possible to have this nice, compact format, without repeating the names on each entry.
var people= new List<Tuple<int, int, string>>() {
{1, 11, "Adam"},
{2, 22, "Bill"},
{3, 33, "Carol"}
}.Select(t => new { Id = t.Item1, Age = t.Item2, Name = t.Item3 });
This gives an IEnumerable - if you want a list that you can add to then just add ToList().
The magic comes from custom extension Add methods for tuples, as described at https://stackoverflow.com/a/27455822/4536527.
public static class TupleListExtensions {
public static void Add<T1, T2>(this IList<Tuple<T1, T2>> list,
T1 item1, T2 item2) {
list.Add(Tuple.Create(item1, item2));
}
public static void Add<T1, T2, T3>(this IList<Tuple<T1, T2, T3>> list,
T1 item1, T2 item2, T3 item3) {
list.Add(Tuple.Create(item1, item2, item3));
}
// and so on...
}
The only thing I don't like is that the types are separated from the names, but if you really don't want to make a new class then this approach will still let you have readable data.

To display the all details for each news post title ie. "news.id" which is the primary key, you need to use GROUP BY clause for "news.id"
SELECT news.id, users.username, news.title, news.date,
news.body, COUNT(comments.id)
FROM news
LEFT JOIN users
ON news.user_id = users.id
LEFT JOIN comments
ON comments.news_id = news.id
GROUP BY news.id

There is another user case where final
keyword can be used i.e. in a method argument:
public void showCaseFinalArgumentVariable(final int someFinalInt){
someFinalInt = 9; // won't compile as the argument is final
}
Can be used for variable which should not be changed.
You can use animated background-position property and sprite image.
I was also facing the same problem and solved through making column as nullable using "?" operator.

Super short answer: designing maintainable websites is difficult with tables, and simple with the standard way to do it.
A website isn't a table, it's a collection of components that interact with each other. Describing it as a table doesn't make sense.
The properties on the style
object are only the styles applied directly to the element (e.g., via a style
attribute or in code). So .style.marginTop
will only have something in it if you have something specifically assigned to that element (not assigned via a style sheet, etc.).
To get the current calculated style of the object, you use either the currentStyle
property (Microsoft) or the getComputedStyle
function (pretty much everyone else).
Example:
var p = document.getElementById("target");
var style = p.currentStyle || window.getComputedStyle(p);
display("Current marginTop: " + style.marginTop);
Fair warning: What you get back may not be in pixels. For instance, if I run the above on a p
element in IE9, I get back "1em"
.
if SQL comes naturally to you, sqldf
package handles ORDER BY
as Codd intended.
The problem is that skew
isn't being subsetted in colour=factor(skew)
, so it's the wrong length. Since subset(skew, product == 'p1')
is the same as subset(skew, product == 'p3')
, in this case it doesn't matter which subset is used. So you can solve your problem with:
p1 <- ggplot(df, aes(x=subset(price, product=='p1'),
y=subset(price, product=='p3'),
colour=factor(subset(skew, product == 'p1')))) +
geom_point(size=2, shape=19)
Note that most R users would write this as the more concise:
p1 <- ggplot(df, aes(x=price[product=='p1'],
y=price[product=='p3'],
colour=factor(skew[product == 'p1']))) +
geom_point(size=2, shape=19)
You can use the "Join" function to create a single string out of the array of labels, like this:
=Join(Parameters!Product.Label, ",")
In C if you implement count line it will never fail. Yes you can get one extra line if there is stray "ENTER KEY" generally at the end of the file.

You can use the phone alias with Inputmask v3
$('#phone').inputmask({ alias: "phone", "clearIncomplete": true });
$(function() {_x000D_
$('input[type="tel"]').inputmask({ alias: "phone", "clearIncomplete": true });_x000D_
});
_x000D_
<label for="phone">Phone</label>_x000D_

To your .eslintrc
which will add all the jest related things to your environment, eliminating the linter errors/warnings.
I did it this way,

The problem is you can't template a typedef, also there is no need to typedef structs in C++.
The following will do what you need
template <typename T>
struct array {
size_t x;
T *ary;
};
Just a note, if you ever see this:
a = x ? : y;
It's a GNU extension to the standard (see https://gcc.gnu.org/onlinedocs/gcc/Conditionals.html#Conditionals).
It is the same as
a = x ? x : y;
EASIEST WAY
python -i helloworld.py #Python 2
python3 -i helloworld.py #Python 3
I would suggest Jquery:
$("#log").html("Type what you want to be shown to the user");
string filePath = HttpContext.Current.Server.MapPath("~/folderName/filename.extension");
OR
string filePath = HttpContext.Server.MapPath("~/folderName/filename.extension");
The normal way would be the IF statement, though simpler than your example:
=IF(INDEX(a,b,c),INDEX(a,b,c),"")
No need to do gyrations with the formula, since zero values trigger the false condition.

To save a bit time:
1) You can mark your app icon images all in finder and drag them into your Assets catalog all at once by dragging into one of the empty slots of the app icon imageset. When you hold your drag over the slot, several of the other slots look selected and when you drop those all will be filled up at once. Note that this works in XCode 8 (I haven't tried XCode 7), but in XCode 9 beta not yet.
2) The "Technical Q&A QA1686" apple documentation site has the sizes per app icon slot already calculated for you in a nice image and also contains the correct image names conventions.
Jquery works differently in IE and other browsers. You can access the last file name by using
alert($('input').attr('value'));
In IE the above alert will give the complete path but in other browsers it will give only the file name.
I think you need to update your libraries so that your VBA code works, your using ms outlook
You could use my tool uhubctl to control USB power per port for compatible USB hubs.
Java projects are exported as Jar executables. When you wanna do a .exe file of a java project, what you can do is 'convert' the JAR to EXE (i remark that i putted between quotes convert because isn't exactly this).
From intelij you gonna be able to generate only the jar
Try following the next example : https://www.genuinecoder.com/convert-java-jar-to-exe/
Deleting variable names with del
is probably something used rarely, but it is something that could not trivially be achieved without a keyword. If you can create a variable name by writing a=1
, it is nice that you can theoretically undo this by deleting a.
It can make debugging easier in some cases as trying to access a deleted variable will raise an NameError.
Python lets you write something like:
class A(object):
def set_a(self, a):
self.a=a
a=A()
a.set_a(3)
if hasattr(a, "a"):
print("Hallo")
If you choose to dynamically add attributes to a class instance, you certainly want to be able to undo it by writing
del a.a
I want to enhance Mr. Kamran Ali's answer with pictorial view.
- Go to "Database" Menu option
- Select the "Reverse Engineer" option.
- A wizard will come. Select from "Stored Connection" and press "Next" button.

You should use Ctrl+shift+enter when using the =SUM(VLOOKUP(A9,A1:D5,{2,3,4,},FALSE)) that results in {=SUM(VLOOKUP(A9,A1:D5,{2,3,4,},FALSE))} en also works.
For another un-free option try edtFTPnet/PRO. It has comprehensive support for SFTP, and also supports FTPS (and of course FTP) if required.
You can bind function as follows, instead of init on load
$("div").css("height", $(window).height());
$(?window?).bind("resize",function() {
$("div").css("height", $(window).height());
});????
To match the title of this question, the value of the id
attribute is:
var myId = $(this).attr('id');
alert( myId );
BUT, of course, the element must already have the id element defined, as:
<option id="opt7" class='select_continent' value='7'>Antarctica</option>
In the OP post, this was not the case.
Note that plain js is faster (in this case):
var myId = this.id
alert( myId );
That is, if you are just storing the returned text into a variable as in the above example. No need for jQuery's wonderfulness here.
Id advice you to use a bit simplier method -
$.post('edit.php', {title: $('input[name="title"]').val() }, function(resp){
alert(resp);
});
try this one, I just feels its syntax is simplier than the $.ajax's one...
1-> Using File Default Config- Angular-cli comes from the ember-cli project. To run the application on specific port, create an .ember-cli file in the project root. Add your JSON config in there:
{ "port": 1337 }
2->Using Command Line Tool Run this command in Angular-Cli
ng serve --port 1234
To change the port number permanently:
Goto
node_modules/angular-cli/commands/server.js
Search for var defaultPort = process.env.PORT || 4200;
(change 4200 to anything else you want).
If you authenticate your clients with Oauth2 I think you will need underscore for at least two of your parameter names:
I have used camelCase in my (not yet published) REST API. While writing the API documentation I have been thinking of changing everything to snake_case so I don't have to explain why the Oauth params are snake_case while other params are not.
It's probably easiest to create your query object directly as:
Test.find({
$and: [
{ $or: [{a: 1}, {b: 1}] },
{ $or: [{c: 1}, {d: 1}] }
]
}, function (err, results) {
...
}
But you can also use the Query#and
helper that's available in recent 3.x Mongoose releases:
Test.find()
.and([
{ $or: [{a: 1}, {b: 1}] },
{ $or: [{c: 1}, {d: 1}] }
])
.exec(function (err, results) {
...
});
it's android:button="@drawable/selector_checkbox"
to make it work
Arel is your friend:
User.where(User.arel_table[:id].gt(200))
Try this:
<script type="text/javascript">
function test()
{
if($('input#field').length==0)
{
$('<input type="button" id="field"/>').appendTo('body');
}
}
</script>
With Firefox, Safari (and other Gecko based browsers) you can easily use textarea.selectionStart, but for IE that doesn't work, so you will have to do something like this:
function getCaret(node) {
if (node.selectionStart) {
return node.selectionStart;
} else if (!document.selection) {
return 0;
}
var c = "\001",
sel = document.selection.createRange(),
dul = sel.duplicate(),
len = 0;
dul.moveToElementText(node);
sel.text = c;
len = dul.text.indexOf(c);
sel.moveStart('character',-1);
sel.text = "";
return len;
}
I also recommend you to check the jQuery FieldSelection Plugin, it allows you to do that and much more...
Edit: I actually re-implemented the above code:
function getCaret(el) {
if (el.selectionStart) {
return el.selectionStart;
} else if (document.selection) {
el.focus();
var r = document.selection.createRange();
if (r == null) {
return 0;
}
var re = el.createTextRange(),
rc = re.duplicate();
re.moveToBookmark(r.getBookmark());
rc.setEndPoint('EndToStart', re);
return rc.text.length;
}
return 0;
}

Adding to Winnie's great answer,
If anyone is not able to find the postgresql.conf file location in your setup, you can always ask the postgres itself.
SHOW config_file;
For me changing the max_connections alone made the trick.
As reported by Tim Anderson
Cross-platform development is a big deal, and will continue to be so until a day comes when everyone uses the same platform. Android? HTML? WebKit? iOS? Windows? Xamarin? Titanum? PhoneGap? Corona? ecc.
Sometimes I hear it said that there are essentially two approaches to cross-platform mobile apps. You can either use an embedded browser control and write a web app wrapped as a native app, as in Adobe PhoneGap/Cordova or the similar approach taken by Sencha, or you can use a cross-platform tool that creates native apps, such as Xamarin Studio, Appcelerator Titanium, or Embarcardero FireMonkey.
Within the second category though, there is diversity. In particular, they vary concerning the extent to which they abstract the user interface.
Here is the trade-off. If you design your cross-platform framework you can have your application work almost the same way on every platform. If you are sharing the UI design across all platforms, it is hard to make your design feel equally right in all cases. It might be better to take the approach adopted by most games, using a design that is distinctive to your app and make a virtue of its consistency across platforms, even though it does not have the native look and feel on any platform.
edit Xamarin v3 in 2014 started offering choice of Xamarin.Forms as well as pure native that still follows the philosophy mentioned here (took liberty of inline edit because such a great answer)
Xamarin Studio on the other hand makes no attempt to provide a shared GUI framework:
We don’t try to provide a user interface abstraction layer that works across all the platforms. We think that’s a bad approach that leads to lowest common denominator user interfaces. (Nat Friedman to Tim Anderson)
This is right; but the downside is the effort involved in maintaining two or more user interface designs for your app.
Comparison about PhoneGap and Titanium it's well reported in Kevin Whinnery blog.
The purpose of PhoneGap is to allow HTML-based web applications to be deployed and installed as native applications. PhoneGap web applications are wrapped in a native application shell, and can be installed via the native app stores for multiple platforms. Additionally, PhoneGap strives to provide a common native API set which is typically unavailable to web applications, such as basic camera access, device contacts, and sensors not already exposed in the browser.
To develop PhoneGap applications, developers will create HTML, CSS, and JavaScript files in a local directory, much like developing a static website. Approaching native-quality UI performance in the browser is a non-trivial task - Sencha employs a large team of web programming experts dedicated full-time to solving this problem. Even so, on most platforms, in most browsers today, reaching native-quality UI performance and responsiveness is simply not possible, even with a framework as advanced as Sencha Touch. Is the browser already “good enough” though? It depends on your requirements and sensibilities, but it is unquestionably less good than native UI. Sometimes much worse, depending on the browser.
PhoneGap is not as truly cross-platform as one might believe, not all features are equally supported on all platforms.
Javascript is not an application scale programming language, too many global scope interactions, different libraries don't often co-exist nicely. We spent many hours trying to get knockout.js and jQuery.mobile play well together, and we still have problems.
Fragmented landscape for frameworks and libraries. Too many choices, and too many are not mature enough.
Strangely enough, for the needs of our app, decent performance could be achieved (not with jQuery.Mobile, though). We tried jqMobi (not very mature, but fast).
Very limited capability for interaction with other apps or cdevice capabilities, and this would not be cross-platform anyway, as there aren't any standards in HTML5 except for a few, like geolocation, camera and local databases.
The goal of Titanium Mobile is to provide a high level, cross-platform JavaScript runtime and API for mobile development (today we support iOS, Android and Windows Phone. Titanium actually has more in common with MacRuby/Hot Cocoa, PHP, or node.js than it does with PhoneGap, Adobe AIR, Corona, or Rhomobile. Titanium is built on two assertions about mobile development: - There is a core of mobile development APIs which can be normalized across platforms. These areas should be targeted for code reuse. - There are platform-specific APIs, UI conventions, and features which developers should incorporate when developing for that platform. Platform-specific code should exist for these use cases to provide the best possible experience.
So for those reasons, Titanium is not an attempt at “write once, run everywhere”. Same as Xamarin.
Titanium are going to do a further step in the direction similar to that of Xamarin. In practice, they will do two layers of different depths: the layer Titanium (in JS), which gives you a bee JS-of-Titanium. If you want to go more low-level, have created an additional layer (called Hyperloop), where (always with JS) to call you back directly to native APIs of SO
Xamarin (originally a division of Novell) in the last 18 months has brought to market its own IDE and snap-in for Visual Studio. The underlining premise of Mono is to create disparate mobile applications using C# while maintaining native UI development strategies.
In addition to creating a visual design platform to develop native applications, they have integrated testing suites, incorporated native library support and a Nuget style component store. Recently they provided iOS visual design through their IDE freeing the developer from opening XCode. In Visual Studio all three platforms are now supported and a cloud testing suite is on the horizon.
From the get go, Xamarin has provided a rich Android visual design experience. I have yet to download or open Eclipse or any other IDE besides Xamarin. What is truly amazing is that I am able to use LINQ to work with collections as well as create custom delegates and events that free me from objective-C and Java limitations. Many of the libraries I have been spoiled with, like Newtonsoft JSON.Net, work perfectly in all three environments.
In my opinion there are several HUGE advantages including
Upgrade for me is use Xamarin and MVVMCross combined. It's still quite a new framework, but it's born from experience of several other frameworks (such as MvvmLight and monocross) and it's now been used in at several released cross platform projects.
My choice after knowing all these framwework, was to select development tool based on product needs. In general, however if you start to use a tool with which you feel comfortable (even if it requires a higher initial overhead) after you'll use it forever.
I chose Xamarin + MVVMCross and I must say to be happy with this choice. I'm not afraid of approach Native SDK for software updates or seeing limited functionality of a system or the most trivial thing a feature graphics. Write code fairly structured (DDD + SOA) is very useful to have a core project shared with native C# views implementation.
Almost there. In your predicate, you want a relative path, so change
./book[/author/name = 'John']
to either
./book[author/name = 'John']
or
./book[./author/name = 'John']
and you will match your element. Your current predicate goes back to the root of the document to look for an author
.
None of the answers so far offer a complete solution. There are quite a few issues to address:
keydown
and keypress
handlers (e.g. backspace and delete keys are suppressed by some browsers).keydown
is not a good idea. There are situations where a keydown does NOT result in a keypress!setTimeout()
style solutions get delayed under Google Chrome/Blink web browsers until the user stops typing.A more correct solution will handle the keypress
, keyup
, input
, and change
events.
Example:
<p><input id="editvalue" type="text"></p>
<p>The text box contains: <span id="labelvalue"></span></p>
<script>
function UpdateDisplay()
{
var inputelem = document.getElementById("editvalue");
var s = inputelem.value;
var labelelem = document.getElementById("labelvalue");
labelelem.innerText = s;
}
// Initial update.
UpdateDisplay();
// Register event handlers.
var inputelem = document.getElementById("editvalue");
inputelem.addEventListener('keypress', UpdateDisplay);
inputelem.addEventListener('keyup', UpdateDisplay);
inputelem.addEventListener('input', UpdateDisplay);
inputelem.addEventListener('change', UpdateDisplay);
</script>
Fiddle:
http://jsfiddle.net/VDd6C/2175/
Handling all four events catches all of the edge cases. When working with input from a user, all types of input methods should be considered and cross-browser and cross-device functionality should be verified. The above code has been tested in Firefox, Edge, and Chrome on desktop as well as the mobile devices I own.
Subtracting 2 Date objects gives you the difference in milliseconds, e.g.:
var diff = Math.abs(new Date('2011/10/09 12:00') - new Date('2011/10/09 00:00'));
Math.abs
is used to be able to use the absolute difference (so new Date('2011/10/09 00:00') - new Date('2011/10/09 12:00')
gives the same result).
Dividing the result by 1000 gives you the number of seconds. Dividing that by 60 gives you the number of minutes. To round to whole minutes, use Math.floor
or Math.ceil
:
var minutes = Math.floor((diff/1000)/60);
In this example the result will be 720

For those like me who would rather not embed their UITableViewController
in a UIViewController
try this:
A custom UITableViewController
subclass can append a mask view to the tableView's superview. Add the mask on viewDidAppear, and remove the mask on viewWillDisappear.
private var statusBarMaskView: UIView!
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
if let superview = self.tableView.superview {
self.statusBarMaskView = UIView(frame: CGRect.zero)
superview.insertSubview(self.statusBarMaskView, aboveSubview: self.tableView)
self.statusBarMaskView.backgroundColor = self.tableView.backgroundColor
// using a nice constraint layout library to set the frame
self.statusBarMaskView.pinTop(to: superview)
self.statusBarMaskView.pinLeft(to: superview)
self.statusBarMaskView.pinRight(to: superview)
self.statusBarMaskView.addHeightConstraint(with: 22.0)
////
}
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
self.statusBarMaskView.removeFromSuperview()
self.statusBarMaskView = nil
}
Flurry Support for iPhone 5 (ARMv7s) As I mentioned in yesterday’s post, Flurry started working on a version of the iOS SDK to support the ARMv7s processor in the new iPhone 5 immediately after the announcement on Wednesday.
I am happy to tell you that the work is done and the SDK is now available on the site.
Ran into the same problem and at first defragmenting seemed to work. But it was for just a short while. Turns out the server the customer was using, was running the Express version
and that has a licensing limit of about 10gb
.
So even though the size was set to "unlimited", it wasn't.
Places you can view the console! Just to have them all in one answer.
Firefox
(you can also now use Firefox's built in developer tools Ctrl+Shift+J (Tools > Web Developer > Error Console), but Firebug is much better; use Firebug)
Safari and Chrome
Basically the same.
https://developers.google.com/chrome-developer-tools/docs/overview
https://developer.apple.com/technologies/safari/developer-tools.html
Internet Explorer
Don't forget you can use compatibility modes to debug IE7 and IE8 in IE9 or IE10
http://msdn.microsoft.com/en-us/library/ie/gg589507(v=vs.85).aspx
http://msdn.microsoft.com/en-us/library/dd565628(v=vs.85).aspx
If you must access the console in IE6 for IE7 use the Firebug Lite bookmarklet
http://getfirebug.com/firebuglite/ look for stable bookmarklet
http://en.wikipedia.org/wiki/Bookmarklet
Opera
http://www.opera.com/dragonfly/
iOS
Works for all iPhones, iPod touch and iPads.
Now with iOS 6 you can view the console through Safari in OS X if you plug in your device. Or you can do so with the emulator, simply open a Safari browser window and go to the "Develop" tab. There you will find options to get the Safari inspector to communicate with your device.
Windows Phone, Android
Both of these have no console built in and no bookmarklet ability. So we use http://jsconsole.com/ type :listen and it will give you a script tag to place in your HTML. From then on you can view your console inside the jsconsole website.
iOS and Android
You can also use http://html.adobe.com/edge/inspect/ to access web inspector tools and the console on any device using their convenient browser plugin.
Older browser problems
Lastly older versions of IE will crash if you use console.log in your code and not have the developer tools open at the same time. Luckily it's an easy fix. Use the below code snippet at the top of your code:
if(!window.console){ window.console = {log: function(){} }; }
This checks to see if the console is present, and if not it sets it to an object with a blank function called log
. This way window.console and window.console.log is never truly undefined.
Here's another option that's longer but may be more readable:
Boolean(Number("0")); // false
Boolean(Number("1")); // true
This is not as easy as it seems, some core library functions don't work when only str is overwritten (checked with Python 2.7), see this thread for examples How to make a class JSON serializable Also, try this
import json
class A(unicode):
def __str__(self):
return 'a'
def __unicode__(self):
return u'a'
def __repr__(self):
return 'a'
a = A()
json.dumps(a)
produces
'""'
and not
'"a"'
as would be expected.
EDIT: answering mchicago's comment:
unicode does not have any attributes -- it is an immutable string, the value of which is hidden and not available from high-level Python code. The json
module uses re
for generating the string representation which seems to have access to this internal attribute. Here's a simple example to justify this:
b = A('b')
print b
produces
'a'
while
json.dumps({'b': b})
produces
{"b": "b"}
so you see that the internal representation is used by some native libraries, probably for performance reasons.

Here are a few options for changing text / label sizes
library(ggplot2)
# Example data using mtcars
a <- aggregate(mpg ~ vs + am , mtcars, function(i) round(mean(i)))
p <- ggplot(mtcars, aes(factor(vs), y=mpg, fill=factor(am))) +
geom_bar(stat="identity",position="dodge") +
geom_text(data = a, aes(label = mpg),
position = position_dodge(width=0.9), size=20)
The size
in the geom_text
changes the size of the geom_text
labels.
p <- p + theme(axis.text = element_text(size = 15)) # changes axis labels
p <- p + theme(axis.title = element_text(size = 25)) # change axis titles
p <- p + theme(text = element_text(size = 10)) # this will change all text size
# (except geom_text)
For this And why size of 10 in geom_text() is different from that in theme(text=element_text()) ?
Yes, they are different. I did a quick manual check and they appear to be in the ratio of ~ (14/5) for geom_text
sizes to theme
sizes.
So a horrible fix for uniform sizes is to scale by this ratio
geom.text.size = 7
theme.size = (14/5) * geom.text.size
ggplot(mtcars, aes(factor(vs), y=mpg, fill=factor(am))) +
geom_bar(stat="identity",position="dodge") +
geom_text(data = a, aes(label = mpg),
position = position_dodge(width=0.9), size=geom.text.size) +
theme(axis.text = element_text(size = theme.size, colour="black"))
This of course doesn't explain why? and is a pita (and i assume there is a more sensible way to do this)
If you have (or create) a single string, you can use np.fromstring:
import numpy as np
x = ["1.1", "2.2", "3.2"]
x = ','.join(x)
x = np.fromstring( x, dtype=np.float, sep=',' )
Note, x = ','.join(x)
transforms the x array to string '1.1, 2.2, 3.2'
. If you read a line from a txt file, each line will be already a string.
Had a quick snoop around for this one, but this looks like it should work. I haven't tested it yet though.
File f = new File("."); // current directory
File[] files = f.listFiles();
for (File file : files) {
if (file.isDirectory()) {
System.out.print("directory:");
} else {

</SCRIPT>
<center class="auto-style19" style="height: 31px">
<Font face="blacksmith" size="large"><strong>
<SCRIPT LANGUAGE="JavaScript">
var header = "You have <I><font color=red>"

header += "days until ICD-10 starts!"
document.write(header)
</SCRIPT>
The HTML inside of my script worked, though I could not explain why.
The first one creates a single lambda function and calls it ten times.
The second one doesn't call the function. It creates 10 different lambda functions. It puts all of those in a list. To make it equivalent to the first you need:
[(lambda x: x*x)(x) for x in range(10)]
Or better yet:
[x*x for x in range(10)]
If you're rolling your own modules specific to your application, you can either:
Keep those (and only those) in your application's /node_modules
folder and move out all the other dependencies to parent ../node_modules
folder. This will work because of how NodeJS CommonJS modules system works by moving up to the parent directory, and so on, until the root of the tree is reached. See: https://nodejs.org/api/modules.html
Or gitignore all /node_modules/*
except your /node_modules/your-modules
. See: Make .gitignore ignore everything except a few files
This use case is pretty awesome. It lets you keep modules you created specifically for your application nicely with it and doesn't clutter with dependencies which can be installed later.
Slight change to the FastArray from above:
'pushtest.vbs
imax = 10000000
value = "Testvalue"
s = imax & " of """ & value & """"
t0 = timer 'Fast array
a = array()
ub = UBound(a)
For i = 0 To imax
If i>ub Then
ReDim Preserve a(Int((ub+10)*1.1))
ub = UBound(a)
End If
a(i) = value
Next
ReDim Preserve a(i-1)
s = s & "[FastArr " & FormatNumber(timer - t0, 3, -1) & "]"
MsgBox s
There is no point in checking UBound(a)
in every cycle of the for if we know exactly when it changes.
I've changed it so that it checks does UBound(a)
just before the for starts and then only every time the ReDim
is called
On my computer the old method took 7.52 seconds for an imax of 10 millions.
The new method took 5.29 seconds for an imax of also 10 millions, which signifies a performance increase of over 20% (for 10 millions tries, obviously this percentage has a direct relationship to the number of tries)
To be quite honest, regular expressions are not the best idea for this type of parsing. The regular expression you posted will probably work great for simple cases, but if things get more complex you are going to have huge problems (same reason why you cant reliably parse HTML with regular expressions). I know you probably don't want to hear this, I know I didn't when I asked the same type of questions, but string parsing became WAY more reliable for me after I stopped trying to use regular expressions for everything.
jTopas is an AWESOME tokenizer that makes it quite easy to write parsers by hand (I STRONGLY suggest jtopas over the standard java scanner/etc.. libraries). If you want to see jtopas in action, here are some parsers I wrote using jTopas to parse this type of file
If you are parsing XML files, you should be using an xml parser library. Dont do it youself unless you are just doing it for fun, there are plently of proven options out there
Just cast it as a const char *. print((const char *)"Yo!") will work fine.
Another example is rasp.yandex.ru, Russian transport timetable service. Its attendance satisfies your requirements.
You can use the root.configure(background='your colour') example:-
import tkinter root=tkiner.Tk() root.configure(background='pink')
There are quite number of tools available for viewing large files. http://download.cnet.com/Large-Text-File-Viewer/3000-2379_4-90541.html This for instance. However, I was successful with larger files viewing in Visual studio. Thought it took some time to load, it worked.
Simple Solution below:-
package com.test;
class MyThread implements Runnable{
@Override
public void run() {
int i=1;
while(true) {
String name=Thread.currentThread().getName();
if(name.equals("task1") && i%2!=0) {
System.out.println(name+"::::"+i);
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}else if(name.equals("task2") && i%2==0){
System.out.println(name+"::::"+i);
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
i++;
}
}
public static void main(String[] args) {
MyThread task1=new MyThread();
MyThread task2=new MyThread();
Thread t1=new Thread(task1,"task1");
Thread t2=new Thread(task2,"task2");
t1.start();
t2.start();
}
}
Very possible the version of pip you're using isn't installing to the version of python you're using. I have a box where this is the case...
try:
which python
python --version
pip -V
If it looks like pip doesn't match your python, then you probably have something like the multiple versions of python and pip I found on my box...
[root@sdpipeline student]# locate bin/pip
/home/student/class/bin/pip
/home/student/class/bin/pip-2.7
/usr/bin/pip
/usr/bin/pip-python
As long as I use /home/student/class/bin/pip (2.7 that matches my python version on that box), then my imports work fine.
You can also try installing pip from source: http://www.pip-installer.org/en/latest/installing.html
There's probably a better way to do this, I'm still learning my way around too, but that's how I solved it -- hope it helps!
Range("A1").value = Environ("Username")
This is better than Application.Username
, which doesn't always supply the Windows username. Thanks to Kyle for pointing this out.
Application Username
is the name of the User set in Excel > Tools > Options Environ("Username")
is the name you registered for Windows; see Control Panel >SystemFor the sake of Pythonic way, here add my answer:

I happened to run into this problem because of missing SELinux permissions. By default, SELinux only allowed apache/httpd to bind to the following ports:
80, 81, 443, 488, 8008, 8009, 8443, 9000
So binding to my httpd.conf
-configured Listen 88
HTTP port and config.d/ssl.conf
-configured Listen 8445
TLS/SSL port would fail with that default SELinux configuration.
To fix my problem, I had to add ports 88 and 8445 to my system's SELinux configuration:
semanage
tools: sudo yum -y install policycoreutils-python
sudo semanage port -a -t http_port_t -p tcp 88
sudo semanage port -a -t http_port_t -p tcp 8445
In python "else if" is spelled "elif".
Also, you need a colon after the elif
and the else
.
Simple answer to a simple question. I had the same problem, when I first started (in the last couple of weeks).
So your code should read:
def function(a):
if a == '1':
print('1a')
elif a == '2':
print('2a')
else:
print('3a')
function(input('input:'))
Got another interesting method:
$array = array('a', 'b', 'c', 'd');
unset($array[2]);
$array = array_merge($array);
Now the $array keys are reset.
It works fine for me, but it's a little tricky :)
Now you have settings for this session set (every time you load session it will be logged).
I also was having the exact same problem in LibreOffice Base. So I just specified a non 'daylight savings time zone' in the connection string.
I tried without the "&serverTimezone=MST" but that failed as well.
I also tried "&serverTimezone=MDT" and that failed, so for some reason, it doesn't like daylight savings time!
This code snippet returns all the numbers in a numpy array between two values:
a = np.array([1, 3, 5, 6, 9, 10, 14, 15, 56] )
a[(a>6)*(a<10)]
It works as following: (a>6) returns a numpy array with True (1) and False (0), so does (a<10). By multiplying these two together you get an array with either a True, if both statements are True (because 1x1 = 1) or False (because 0x0 = 0 and 1x0 = 0).
The part a[...] returns all values of array a where the array between brackets returns a True statement.
Of course you can make this more complicated by saying for instance
...*(1-a<10)
which is similar to an "and Not" statement.
On Scientific Linux 6 (similar to CentOS 6-- SL is now replaced by CentOS, AIUI), I had to use /usr/sbin/prelink -av -mR
which I found suggested at https://stelfox.net/blog/2014/08/dependency-prelink-issues/
Until I did that, I got a cc1 error gcc: error trying to exec 'cc1': execvp: No such file or directory
when I tried to compile, and gcc --version reported 4.2.2 instead of 4.4.7, despite that version being reported by yum.
It may or may not be related, but the system had run out of space on /var
Your DateFormat
pattern does not match you input date String
. You could use
new SimpleDateFormat("dd-MMM-yyyy")
Error checking and handling is the programmer's friend. Check the return values of the initializing and executing cURL functions. curl_error()
and curl_errno()
will contain further information in case of failure:
try {
$ch = curl_init();
// Check if initialization had gone wrong*
if ($ch === false) {
throw new Exception('failed to initialize');
}
curl_setopt($ch, CURLOPT_URL, 'http://example.com/');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt(/* ... */);
$content = curl_exec($ch);
// Check the return value of curl_exec(), too
if ($content === false) {
throw new Exception(curl_error($ch), curl_errno($ch));
}
/* Process $content here */
// Close curl handle
curl_close($ch);
} catch(Exception $e) {
trigger_error(sprintf(
'Curl failed with error #%d: %s',
$e->getCode(), $e->getMessage()),
E_USER_ERROR);
}
* The curl_init()
manual states:
Returns a cURL handle on success, FALSE on errors.
I've observed the function to return FALSE
when you're using its $url
parameter and the domain could not be resolved. If the parameter is unused, the function might never return FALSE
. Always check it anyways, though, since the manual doesn't clearly state what "errors" actually are.
Just a supplement here.
The following question is that what if I want more subplots in the figure?
As mentioned in the Doc, we can use fig = plt.subplots(nrows=2, ncols=2)
to set a group of subplots with grid(2,2) in one figure object.
Then as we know, the fig, ax = plt.subplots()
returns a tuple, let's try fig, ax1, ax2, ax3, ax4 = plt.subplots(nrows=2, ncols=2)
firstly.
ValueError: not enough values to unpack (expected 4, got 2)
It raises a error, but no worry, because we now see that plt.subplots()
actually returns a tuple with two elements. The 1st one must be a figure object, and the other one should be a group of subplots objects.
So let's try this again:
fig, [[ax1, ax2], [ax3, ax4]] = plt.subplots(nrows=2, ncols=2)
and check the type:
type(fig) #<class 'matplotlib.figure.Figure'>
type(ax1) #<class 'matplotlib.axes._subplots.AxesSubplot'>
Of course, if you use parameters as (nrows=1, ncols=4), then the format should be:
fig, [ax1, ax2, ax3, ax4] = plt.subplots(nrows=1, ncols=4)
So just remember to keep the construction of the list as the same as the subplots grid we set in the figure.
Hope this would be helpful for you.
While the answer from alireza is correct, it has one gotcha:
You can't install Microsoft Visual C++ 2015 redist (runtime) unless you have Windows Update KB2999226 installed (at least on Windows 7 64-bit SP1).
If you are looking for the solution in Android Studio :
I tried several of the suggestions above and unfortunately none of them worked. We have a "Log" index in our lower environment where apps write their errors. It is a single node cluster. What solved it for me was checking the YML configuration file for the node and seeing that it still had the default setting "gateway.expected_nodes: 2". This was overriding any other settings we had. Whenever we would create an index on this node it would try to spread 3 out of 5 shards to the phantom 2nd node. These would therefore appear as unassigned and they could never be moved to the 1st and only node.
The solution was editing the config, changing the setting "gateway.expected_nodes" to 1, so it would quit looking for its never-to-be-found brother in the cluster, and restarting the Elastic service instance. Also, I had to delete the index, and create a new one. After creating the index, the shards all showed up on the 1st and only node, and none were unassigned.
# Set how many nodes are expected in this cluster. Once these N nodes
# are up (and recover_after_nodes is met), begin recovery process immediately
# (without waiting for recover_after_time to expire):
#
# gateway.expected_nodes: 2
gateway.expected_nodes: 1
InputProperty[] ip = new InputProperty[nvPairs.Length];
Or, you can use a list like so:
List<InputProperty> list = new List<InputProperty>();
InputProperty ip = new (..);
list.Add(ip);
update.items = list.ToArray();
Another thing I'd like to point out, in C# you can delcare your int variable use in a for loop right inside the loop:
for(int i = 0; i<nvPairs.Length;i++
{
.
.
}
And just because I'm in the mood, here's a cleaner way to do this method IMO:
private Update BuildMetaData(MetaData[] nvPairs)
{
Update update = new Update();
var ip = new List<InputProperty>();
foreach(var nvPair in nvPairs)
{
if (nvPair == null) break;
var inputProp = new InputProperty
{
Name = "udf:" + nvPair.Name,
Val = nvPair.Value
};
ip.Add(inputProp);
}
update.Items = ip.ToArray();
return update;
}

I too have struggled with this problem over the past few days and I too turned to stack overflow for answers.
However, no one seems to mention the simplest way to import data into MySQL is actually through their very own import data wizard tool!!
Just right-click on the table and it comes up there.
None of the above answers helped me, so just use this if you're stuck! :)
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() - $img.height()) / 2;
// Note that the above calculations assume your left margin is
// equal to your right margin, top to bottom, etc. and the same
// for borders.
var x = (ev.clientX + xMargin) - offset.left;
var y = (ev.clientY + yMargin) - offset.top;
alert('clicked at x: ' + x + ', y: ' + y);
});
});
</script>
I used Palash's answer given above but it was somewhat incomplete, I had to provide permission like this
Intent intent = new Intent(Intent.ACTION_VIEW);
Uri uri;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
uri = FileProvider.getUriForFile(this, getPackageName() + ".provider", new File(path));
List<ResolveInfo> resInfoList = getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
for (ResolveInfo resolveInfo : resInfoList) {
String packageName = resolveInfo.activityInfo.packageName;
grantUriPermission(packageName, uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
}
}else {
uri = Uri.fromFile(new File(path));
}
intent.setDataAndType(uri, "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
You need to use : "$@"
(WITH the quotes) or "${@}"
(same, but also telling the shell where the variable name starts and ends).
(and do NOT use : $@
, or "$*"
, or $*
).
ex:
#testscript1:
echo "TestScript1 Arguments:"
for an_arg in "$@" ; do
echo "${an_arg}"
done
echo "nb of args: $#"
./testscript2 "$@" #invokes testscript2 with the same arguments we received
I'm not sure I understood your other requirement ( you want to invoke './testscript2' in single quotes?) so here are 2 wild guesses (changing the last line above) :
'./testscript2' "$@" #only makes sense if "/path/to/testscript2" containes spaces?
./testscript2 '"some thing" "another"' "$var" "$var2" #3 args to testscript2
Please give me the exact thing you are trying to do
edit: after his comment saying he attempts tesscript1 "$1" "$2" "$3" "$4" "$5" "$6" to run : salt 'remote host' cmd.run './testscript2 $1 $2 $3 $4 $5 $6'
You have many levels of intermediate: testscript1 on host 1, needs to run "salt", and give it a string launching "testscrit2" with arguments in quotes...
You could maybe "simplify" by having:
#testscript1
#we receive args, we generate a custom script simulating 'testscript2 "$@"'
theargs="'$1'"
shift
for i in "$@" ; do
theargs="${theargs} '$i'"
done
salt 'remote host' cmd.run "./testscript2 ${theargs}"
if THAt doesn't work, then instead of running "testscript2 ${theargs}", replace THE LAST LINE above by
echo "./testscript2 ${theargs}" >/tmp/runtestscript2.$$ #generate custom script locally ($$ is current pid in bash/sh/...)
scp /tmp/runtestscript2.$$ user@remotehost:/tmp/runtestscript2.$$ #copy it to remotehost
salt 'remotehost' cmd.run "./runtestscript2.$$" #the args are inside the custom script!
ssh user@remotehost "rm /tmp/runtestscript2.$$" #delete the remote one
rm /tmp/runtestscript2.$$ #and the local one
I had a similar problem.
I would also look at this answer: Is there a high resolution (microsecond, nanosecond) DateTime object available for the CLR?.
About half-way down is an answer by "Robert P" with some extension functions I found useful.
The easiest way to find the best fit in R is to code the model as:
lm.1 <- lm(y ~ x + I(x^2) + I(x^3) + I(x^4) + ...)
After using step down AIC regression
lm.s <- step(lm.1)
I do it this way:
The html:
<head>
<style type="text/css"> <? require_once('xCss.php'); ?> </style>
</head>
The xCss.php:
<? // place here your vars
$fntBtn = 'bold 14px Arial'
$colBorder = '#556677' ;
$colBG0 = '#dddddd' ;
$colBG1 = '#44dddd' ;
$colBtn = '#aadddd' ;
// here goes your css after the php-close tag:
?>
button { border: solid 1px <?= $colBorder; ?>; border-radius:4px; font: <?= $fntBtn; ?>; background-color:<?= $colBtn; ?>; }
The HTML standard includes an internal structured cloning/serialization algorithm that can create deep clones of objects. It is still limited to certain built-in types, but in addition to the few types supported by JSON it also supports Dates, RegExps, Maps, Sets, Blobs, FileLists, ImageDatas, sparse Arrays, Typed Arrays, and probably more in the future. It also preserves references within the cloned data, allowing it to support cyclical and recursive structures that would cause errors for JSON.
The v8
module in Node.js currently (as of Node 11) exposes the structured serialization API directly, but this functionality is still marked as "experimental", and subject to change or removal in future versions. If you're using a compatible version, cloning an object is as simple as:
const v8 = require('v8');
const structuredClone = obj => {
return v8.deserialize(v8.serialize(obj));
};
Browsers do not currently provide a direct interface for the structured cloning algorithm, but a global structuredClone()
function has been discussed in whatwg/html#793 on GitHub. As currently proposed, using it for most purposes would be as simple as:
const clone = structuredClone(original);
Unless this is shipped, browsers' structured clone implementations are only exposed indirectly.
The lower-overhead way to create a structured clone with existing APIs is to post the data through one port of a MessageChannels. The other port will emit a message
event with a structured clone of the attached .data
. Unfortunately, listening for these events is necessarily asynchronous, and the synchronous alternatives are less practical.
class StructuredCloner {
constructor() {
this.pendingClones_ = new Map();
this.nextKey_ = 0;
const channel = new MessageChannel();
this.inPort_ = channel.port1;
this.outPort_ = channel.port2;
this.outPort_.onmessage = ({data: {key, value}}) => {
const resolve = this.pendingClones_.get(key);
resolve(value);
this.pendingClones_.delete(key);
};
this.outPort_.start();
}
cloneAsync(value) {
return new Promise(resolve => {
const key = this.nextKey_++;
this.pendingClones_.set(key, resolve);
this.inPort_.postMessage({key, value});
});
}
}
const structuredCloneAsync = window.structuredCloneAsync =
StructuredCloner.prototype.cloneAsync.bind(new StructuredCloner);
const main = async () => {
const original = { date: new Date(), number: Math.random() };
original.self = original;
const clone = await structuredCloneAsync(original);
// They're different objects:
console.assert(original !== clone);
console.assert(original.date !== clone.date);
// They're cyclical:
console.assert(original.self === original);
console.assert(clone.self === clone);
// They contain equivalent values:
console.assert(original.number === clone.number);
console.assert(Number(original.date) === Number(clone.date));
console.log("Assertions complete.");
};
main();
There are no good options for creating structured clones synchronously. Here are a couple of impractical hacks instead.
history.pushState()
and history.replaceState()
both create a structured clone of their first argument, and assign that value to history.state
. You can use this to create a structured clone of any object like this:
const structuredClone = obj => {
const oldState = history.state;
history.replaceState(obj, null);
const clonedObj = history.state;
history.replaceState(oldState, null);
return clonedObj;
};

Though synchronous, this can be extremely slow. It incurs all of the overhead associated with manipulating the browser history. Calling this method repeatedly can cause Chrome to become temporarily unresponsive.
The Notification
constructor creates a structured clone of its associated data. It also attempts to display a browser notification to the user, but this will silently fail unless you have requested notification permission. In case you have the permission for other purposes, we'll immediately close the notification we've created.
const structuredClone = obj => {
const n = new Notification('', {data: obj, silent: true});
n.onshow = n.close.bind(n);

The main articles are XML, so inserting them into the db is a bit more of a problem, but you might find there are other files there that suit you. For example, the inter-page links SQL file is 2.3GB compressed. Have a look at https://en.wikipedia.org/wiki/Wikipedia:Database_download for more info.

For opening many files at once or for long file paths, it may be useful to break things up over multiple lines. From the Python Style Guide as suggested by @Sven Marnach in comments to another answer:
with open('/path/to/InFile.ext', 'r') as file_1, \
open('/path/to/OutFile.ext', 'w') as file_2:
file_2.write(file_1.read())
private fun generateKeyHash(): String? {try {
val info =packageManager.getPackageInfo(packageName, PackageManager.GET_SIGNATURES)
for (signature in info.signatures) {
val md: MessageDigest = MessageDigest.getInstance("SHA")
md.update(signature.toByteArray())
return String(Base64.encode(md.digest(), 0))
}
} catch (e: Exception) {
Log.e("exception", e.toString())
}
return "key hash not found"
}
$('#elm').removeAttr('class');
no longer class attr wil be present in "elm".
CERAS is a class name which cannot be assigned. As the class implements IDisposable a typical usage would be:
using (CERas.CERAS ceras = new CERas.CERAS())
{
// call some method on ceras
}
You need to configure a raw HttpClient with SSL support, something like this:
@Test
public void givenAcceptingAllCertificatesUsing4_4_whenUsingRestTemplate_thenCorrect()
throws ClientProtocolException, IOException {
CloseableHttpClient httpClient
= HttpClients.custom()
.setSSLHostnameVerifier(new NoopHostnameVerifier())
.build();
HttpComponentsClientHttpRequestFactory requestFactory
= new HttpComponentsClientHttpRequestFactory();
requestFactory.setHttpClient(httpClient);
ResponseEntity<String> response
= new RestTemplate(requestFactory).exchange(
urlOverHttps, HttpMethod.GET, null, String.class);
assertThat(response.getStatusCode().value(), equalTo(200));
}
Right click your project, hit "Clean and Build". Netbeans does the rest.
under the dist directory of your app, you should find a pretty looking .war all ready for deployment.
