Simple solution for vertical align middle... for me it works like a charm
ul{display:table; text-align:center; margin:0 auto;}
li{display:inline-block; text-align:center;}
li.items_inside_li{display:inline-block; vertical-align:middle;}
I think the problem is with the datatype of the data you are passing Caused by: java.sql.SQLException: Invalid column type: 1111
check the datatypes you pass with the actual column datatypes may be there can be some mismatch or some constraint violation with null
NSString *string = [NSString stringWithFormat:@"%d", theinteger];
I am surprised that the connection string works for you, because it is missing a semi-colon. Set is only used with objects, so you would not say Set strNaam.
Set cn = CreateObject("ADODB.Connection")
With cn
.Provider = "Microsoft.Jet.OLEDB.4.0"
.ConnectionString = "Data Source=D:\test.xls " & _
";Extended Properties=""Excel 8.0;HDR=Yes;"""
.Open
End With
strQuery = "SELECT * FROM [Sheet1$E36:E38]"
Set rs = cn.Execute(strQuery)
Do While Not rs.EOF
For i = 0 To rs.Fields.Count - 1
Debug.Print rs.Fields(i).Name, rs.Fields(i).Value
strNaam = rs.Fields(0).Value
Next
rs.MoveNext
Loop
rs.Close
There are other ways, depending on what you want to do, such as GetString (GetString Method Description).
With jQuery:
$('form').submit(function () {
// Validate here
if (pass)
return true;
else
return false;
});
I think you can bring specific access to user and command with visudo
something like this:
nobody ALL = NOPASSWD: /path/to/osascript myscript.scpt
and with php:
@exec("sudo /path/to/osascript myscript.scpt ");
supposing nobody
user is running apache.
For a set of images (each image has 3 dimensions), where I wanted to reject outliers for each pixel I used:
mean = np.mean(imgs, axis=0)
std = np.std(imgs, axis=0)
mask = np.greater(0.5 * std + 1, np.abs(imgs - mean))
masked = np.multiply(imgs, mask)
Then it is possible to compute the mean:
masked_mean = np.divide(np.sum(masked, axis=0), np.sum(mask, axis=0))
(I use it for Background Subtraction)
As @Devart says, the total length of your index is too long.
The short answer is that you shouldn't be indexing such long VARCHAR columns anyway, because the index will be very bulky and inefficient.
The best practice is to use prefix indexes so you're only indexing a left substring of the data. Most of your data will be a lot shorter than 255 characters anyway.
You can declare a prefix length per column as you define the index. For example:
...
KEY `index` (`parent_menu_id`,`menu_link`(50),`plugin`(50),`alias`(50))
...
But what's the best prefix length for a given column? Here's a method to find out:
SELECT
ROUND(SUM(LENGTH(`menu_link`)<10)*100/COUNT(`menu_link`),2) AS pct_length_10,
ROUND(SUM(LENGTH(`menu_link`)<20)*100/COUNT(`menu_link`),2) AS pct_length_20,
ROUND(SUM(LENGTH(`menu_link`)<50)*100/COUNT(`menu_link`),2) AS pct_length_50,
ROUND(SUM(LENGTH(`menu_link`)<100)*100/COUNT(`menu_link`),2) AS pct_length_100
FROM `pds_core_menu_items`;
It tells you the proportion of rows that have no more than a given string length in the menu_link
column. You might see output like this:
+---------------+---------------+---------------+----------------+
| pct_length_10 | pct_length_20 | pct_length_50 | pct_length_100 |
+---------------+---------------+---------------+----------------+
| 21.78 | 80.20 | 100.00 | 100.00 |
+---------------+---------------+---------------+----------------+
This tells you that 80% of your strings are less than 20 characters, and all of your strings are less than 50 characters. So there's no need to index more than a prefix length of 50, and certainly no need to index the full length of 255 characters.
PS: The INT(1)
and INT(32)
data types indicates another misunderstanding about MySQL. The numeric argument has no effect related to storage or the range of values allowed for the column. INT
is always 4 bytes, and it always allows values from -2147483648 to 2147483647. The numeric argument is about padding values during display, which has no effect unless you use the ZEROFILL
option.
If you're using this purely to reference the function in the onclick attribute, this seems like a very bad idea. Inline events are a bad idea in general.
I would suggest the following:
function addEvent(elm, evType, fn, useCapture) {
if (elm.addEventListener) {
elm.addEventListener(evType, fn, useCapture);
return true;
}
else if (elm.attachEvent) {
var r = elm.attachEvent('on' + evType, fn);
return r;
}
else {
elm['on' + evType] = fn;
}
}
handler = function(){
showHref(el);
}
showHref = function(el) {
alert(el.href);
}
var el = document.getElementById('linkid');
addEvent(el, 'click', handler);
If you want to call the same function from other javascript code, simulating a click to call the function is not the best way. Consider:
function doOnClick() {
showHref(document.getElementById('linkid'));
}
Nicely explained above!
For all those who may suffer like me to get this working in a localized Windows (mine is XP in Slovak), you may try to replace the %
with a !
So:
SET TEXT=Hello World
SET SUBSTRING=!TEXT:~3,5!
ECHO !SUBSTRING!
git log --format="%h" | tail -1
gives you the commit hash (ie 0dd89fb
), which you can feed into other commands, by doing something like
git diff `git log --format="%h" --after="1 day"| tail -1`..HEAD
to view all the commits in the last day.
You are facing issue in
s1.name="Paolo";
because, in the LHS, you're using an array type, which is not assignable.
To elaborate, from C11
, chapter §6.5.16
assignment operator shall have a modifiable lvalue as its left operand.
and, regarding the modifiable lvalue, from chapter §6.3.2.1
A modifiable lvalue is an lvalue that does not have array type, [...]
You need to use strcpy()
to copy into the array.
That said, data s1 = {"Paolo", "Rossi", 19};
works fine, because this is not a direct assignment involving assignment operator. There we're using a brace-enclosed initializer list to provide the initial values of the object. That follows the law of initialization, as mentioned in chapter §6.7.9
Each brace-enclosed initializer list has an associated current object. When no designations are present, subobjects of the current object are initialized in order according to the type of the current object: array elements in increasing subscript order, structure members in declaration order, and the first named member of a union.[....]
There are many possibilities to do this in R. Here are some of them:
df <- read.table(header = TRUE, text = 'Gene Value
A 12
A 10
B 3
B 5
B 6
C 1
D 3
D 4')
# aggregate
aggregate(df$Value, by = list(df$Gene), max)
aggregate(Value ~ Gene, data = df, max)
# tapply
tapply(df$Value, df$Gene, max)
# split + lapply
lapply(split(df, df$Gene), function(y) max(y$Value))
# plyr
require(plyr)
ddply(df, .(Gene), summarise, Value = max(Value))
# dplyr
require(dplyr)
df %>% group_by(Gene) %>% summarise(Value = max(Value))
# data.table
require(data.table)
dt <- data.table(df)
dt[ , max(Value), by = Gene]
# doBy
require(doBy)
summaryBy(Value~Gene, data = df, FUN = max)
# sqldf
require(sqldf)
sqldf("select Gene, max(Value) as Value from df group by Gene", drv = 'SQLite')
# ave
df[as.logical(ave(df$Value, df$Gene, FUN = function(x) x == max(x))),]
As the other commenters are suggesting the most efficient way to do it seems to be:
if ($(selector).length ) {
// Do something
}
If you absolutely must have an exists() function - which will be slower- you can do:
jQuery.fn.exists = function(){return this.length>0;}
Then in your code you can use
if ($(selector).exists()) {
// Do something
}

If property hibernate.ddl-auto = update
, then it will not create the tables automatically.
To create tables automatically, you need to set the property to
hibernate.ddl-auto = create
The list of option which is used in the spring boot are
validate: validate the schema, makes no changes to the database.
update: update the schema.
create: creates the schema, destroying previous data.
create-drop: drop the schema at the end of the session
none: is all other cases
So for the first time you can set it to create and then next time on-wards you should set it to update.
for me this worked
RewriteEngine on
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]
You could use find
to solve your problem
const data = [{"a": 1}, {"b": 2}]
const item = {"b": 2}
find(data, item)
// > true
Quickest and easiest way without a doubt is Ctrl+L.
This is the same for OS X on the terminal.

As you've noticed, you have no selectivity to your update statement so it is updating your entire table. If you want to update specific rows (ie where the IDs match) you probably want to do a coordinated subquery.
However, since you are using Oracle, it might be easier to create a materialized view for your query table and let Oracle's transaction mechanism handle the details. MVs work exactly like a table for querying semantics, are quite easy to set up, and allow you to specify the refresh interval.
I guess the only way to do this is by utilizing reusable fragments:
fragment UserFragment on Users {
id
username
count
}
FetchUsers {
users(id: "2") {
...UserFragment
}
}
You need to have a SQLite JDBC driver in your classpath.
Taro L. Saito (xerial) forked the Zentus project and now maintains it under the name sqlite-jdbc. It bundles the native drivers for major platforms so you don't need to configure them separately.
Also try to update your browser because Angular need latest browser. check: https://angular.io/guide/browser-support
I fixed console.log issue after updating latest browser.
If you have homeBrew installed, this is all you have to do:
brew install macvim
brew linkapps
Then type mvim
in your terminal to run MacVim.
I encountered this issue, and I managed to identify a specific cause, which isn't mentioned above either in answers or the question.
I am running a full js stack, angular front end and node back end on SSL, and the API is on a different domain running on port 8081, so I am doing CORS requests and withCredentials as I am dropping a session cookie from the API
So specifically my scenario was: POST request, withCredentials to port 8081 caused the "CAUTION: provisional headers are shown" message in the inspector and also of course blocked the request all together.
My solution was to set up apache to proxy pass the request from the usual SSL port of 443 to the node SSL port of 8081 (node has to be on a higher port as it cannot be ran as root in prod). So I guess Chrome doesn't like SSL requests to unconventional SSL ports, but perhaps their error message could be more specific.
I've made an XCode 4 project template that lets you make a universal framework as easily as making a regular library.
If you don't want to show the series names in the legend you can disable them by setting showInLegend:false
.
example:

}]
You get other options here.
With netcat and awk you can handle the server response manually:

Jeff Smith has blogged showing, what I believe is the superior method to get CSV output from SQL Developer. Jeff's method is shown as Method 1 below:
Method 1
Add the comment /*csv*/
to your SQL query and run the query as a script (using F5 or the 2nd execution button on the worksheet toolbar)
That's it.
Method 2
Run a query
Right click and select unload.
Update. In Sql Developer Version 3.0.04 unload has been changed to export Thanks to Janis Peisenieks for pointing this out
Revised screen shot for SQL Developer Version 3.0.04
From the format drop down select CSV
And follow the rest of the on screen instructions.
The GPL mkfile is just a (ba)sh script wrapper around dd; BSD's mkfile just memsets a buffer with non-zero and writes it repeatedly. I would not expect the former to out-perform dd. The latter might edge out dd if=/dev/zero slightly since it omits the reads, but anything that does significantly better is probably just creating a sparse file.
Absent a system call that actually allocates space for a file without writing data (and Linux and BSD lack this, probably Solaris as well) you might get a small improvement in performance by using ftrunc(2)/truncate(1) to extend the file to the desired size, mmap the file into memory, then write non-zero data to the first bytes of every disk block (use fgetconf to find the disk block size).
a=[]
def showmatrix (a,m,n):
for i in range (m):
for j in range (n):
k=int(input("enter the number")

print('\t')
def showtranspose(a,m,n):
for j in range(n):
for i in range(m):
print(a[i][j]),
print('\t')
a=((89,45,50),(130,120,40),(69,79,57),(78,4,8))
print("given matrix of order 4x3 is :")
showmatrix(a,4,3)
print("Transpose matrix is:")
showtranspose(a,4,3)
I believe this is the most simple in all aspects unless you call the validate function be other means. With no/null/empty value to your first option is easier to validate. You could also eliminate the first option and start with the most popular card type.
<form name="myForm">
<select id="cardtype" name="cards">
<option value="">--- Please select ---</option>
<option value="mastercard" selected="selected">Mastercard</option>
<option value="maestro">Maestro</option>
<option value="solo">Solo (UK only)</option>
<option value="visaelectron">Visa Electron</option>
<option value="visadebit">Visa Debit</option>
</select><br />
<input type="submit" name="submit" class="button" value="SUBMIT" onmouseover="validate()"></form>
<script>
function validate() {
if (document.myform.cards.value == "") {
alert("Please select a card type");
document.myForm.cards.focus();
}
</script>
As in TDD & BDD you/ team focus the most on test and behavior of the system than code implementation.
Similar way when system analyst, product owner, development team and ofcourse the code - entities/ classes, variables, functions, user interfaces processes communicate using the same language, its called Domain Driven Design
DDD is a thought process. When modeling a design of software you need to keep business domain/process in the center of attention rather than data structures, data flows, technology, internal and external dependencies.
There are many approaches to model systerm using DDD
In very naive words, an object which
I try like this with function then calling if needed a this function. Has been worked for me.
function modal_fix() {
var a = $(".modal"),
b = $("body");
a.on("shown.bs.modal", function () {
b.hasClass("modal-open") || b.addClass("modal-open");
});
}
In order to avoid dealing with these very boring issues, I advise you to always parse your data with the standard and unique SQL/ISO date format which is YYYY-MM-DD. Your queries will then work internationally, no matter what the date parameters are on your main server or on the querying clients (where local date settings might be different than main server settings)!
Use @JsonValue:
public class User {
int id;
String name;
@JsonValue
public int getId() {
return id;
}
}
@JsonValue only works on methods so you must add the getId method. You should be able to skip your custom serializer altogether.
I encountered exact the same problem with maven thrift plugin. Here's my solution which requires no need to mess up your pom.xml:
Use command line maven utility mvn
mvn eclipse:eclipse
to create a eclipse project
Import the project in eclipse. Remember to use
File > Import > General > Existing Projects into Workspace
to add the project into your workspace.
This should fix the problem.
Just run graphics.off()
before plotting your data.
This instruction solved my error. So, it's harmless to try it before taking a more complex solution.
I would like to add that in case in you create local variables within the loop, they need to be expanded using the bang(!) notation as well. Extending the example at https://stackoverflow.com/a/2919699 above, if we want to create counter-based output filenames
set TEXT_T="myfile.txt"
set /a c=1
setlocal ENABLEDELAYEDEXPANSION
FOR /F "tokens=1 usebackq" %%i in (%TEXT_T%) do (
set /a c=c+1
set OUTPUT_FILE_NAME=output_!c!.txt
echo Output file is !OUTPUT_FILE_NAME!
echo %%i, !c!
)
endlocal
Here is a slight variation on answer offered by jfriend00:
$.fn.hasAnyClass = function() {
var classes = arguments[0].split(" ");
for (var i = 0; i < classes.length; i++) {
if (this.hasClass(classes[i])) {
return true;
}
}
return false;
}
Allows use of same syntax as .addClass() and .removeClass(). e.g., .hasAnyClass('m320 m768')
Needs bulletproofing, of course, as it assumes at least one argument.
Just use .get(0) to grab the native element, and get its outerHTML property:
var $elem = $('<a href="#">Some element</a>');
console.log("HTML is: " + $elem.get(0).outerHTML);
I added opacity to the line, so it seems thinner:
<hr style="opacity: 0.25">
When passing an array as a parameter, this
void arraytest(int a[])
means exactly the same as
void arraytest(int *a)
so you are modifying the values in main.
For historical reasons, arrays are not first class citizens and cannot be passed by value.
You can try:
<label id ="label_id"></label>
$("#label_id").html('value');
I have checked the <%= csrf_meta_tags %> are present and clearing cookies in browser worked for me.

var stream = request(...).pipe(...);
stream.on('finish', function () { ... });

It is now possible with the HTML5 webapp manifest. See below.
Original answer:
You can't lock a website or a web application in a specific orientation. It goes against the natural behaviour of the device.
You can detect the device orientation with CSS3 media queries like this:
@media screen and (orientation:portrait) {
// CSS applied when the device is in portrait mode
}
@media screen and (orientation:landscape) {
// CSS applied when the device is in landscape mode
}
Or by binding a JavaScript orientation change event like this:
document.addEventListener("orientationchange", function(event){
switch(window.orientation)
{
case -90: case 90:
/* Device is in landscape mode */
break;
default:
/* Device is in portrait mode */
}
});
Update on November 12, 2014: It is now possible with the HTML5 webapp manifest.
As explained on html5rocks.com, you can now force the orientation mode using a manifest.json
file.
You need to include those line into the json file:
{
"display": "standalone", /* Could be "fullscreen", "standalone", "minimal-ui", or "browser" */
"orientation": "landscape", /* Could be "landscape" or "portrait" */
...
}
And you need to include the manifest into your html file like this:
<link rel="manifest" href="manifest.json">
Not exactly sure what the support is on the webapp manifest for locking orientation mode, but Chrome is definitely there. Will update when I have the info.
For short: No
Explanation:
According to the official docs: https://docs.microsoft.com/en-us/sql/t-sql/statements/create-table-transact-sql?view=sql-server-ver15
If a local temporary table is created in a stored procedure or application that can be executed at the same time by several users, the Database Engine must be able to distinguish the tables created by the different users. The Database Engine does this by internally appending a numeric suffix to each local temporary table name. The full name of a temporary table as stored in the sysobjects table in tempdb is made up of the table name specified in the CREATE TABLE statement and the system-generated numeric suffix. To allow for the suffix, table_name specified for a local temporary name cannot exceed 116 characters.
Here is another approach using getter and setter functions for the model.
@Component({
selector: 'input-language',
template: `
…
<input
type="text"
placeholder="Language"
[(ngModel)]="query"
/>
`,
})
export class InputLanguageComponent {
set query(value) {
this._query = value;
console.log('query set to :', value)
}
get query() {
return this._query;
}
}
As a db driver, there is also oursql. Some of the reasons listed on that link, which say why oursql is better:
- oursql has real parameterization, sending the SQL and data to MySQL completely separately.
- oursql allows text or binary data to be streamed into the database and streamed out of the database, instead of requiring everything to be buffered in the client.
- oursql can both insert rows lazily and fetch rows lazily.
- oursql has unicode support on by default.
- oursql supports python 2.4 through 2.7 without any deprecation warnings on 2.6+ (see PEP 218) and without completely failing on 2.7 (see PEP 328).
- oursql runs natively on python 3.x.
Very similar to mysqldb:
import oursql
db_connection = oursql.connect(host='127.0.0.1',user='foo',passwd='foobar',db='db_name')
cur=db_connection.cursor()
cur.execute("SELECT * FROM `tbl_name`")
for row in cur.fetchall():
print row[0]
The tutorial in the documentation is pretty decent.
And of course for ORM SQLAlchemy is a good choice, as already mentioned in the other answers.

Your csv is malformed. The output is not three loopings but just one output. To ensure that this is a single loop, add a counter and increment it with every loop. It should only count to one.
This is what your code sees
0,Filipe,19,M\n1,Maria,20,F\n2,Walter,60,M
Try this
0,Filipe,19,M
1,Maria,20,F
2,Walter,60,M

}
Off the top of my head:
GetType()
instead of typeof(Page)
in order to bind the script to your actual page class instead of the base class,Page.UniqueID
, which is not that meaningful since it's supposed to be used by named controls,PreRender
phase:protected void Page_PreRender(object sender, EventArgs e)
{
ScriptManager.RegisterStartupScript(this, GetType(), "YourUniqueScriptKey",
"alert('This pops up');", true);
}

If your original data is in column form with multiple columns and the first entry of your original data in C42, and you want your new (down-sampled) data to be in column form as well, but only every seventh row, then you will also need to subtract out the row number of the first entry, like so:
=OFFSET(C$42,(ROW(C42)-ROW(C$42))*7,0)
It appears that the issue has to do (at least in mine and a few others) with invalid (corrupt?) innodb log files. Generally speaking, they simply need to be recreated.
Here are solutions, most of which require a restart of mysql.
I've not met that particular package before, but it says it's for client-side HTTP authentication, which I've been able to do on Android using the java.net
APIs, like so:
Authenticator.setDefault(new Authenticator(){
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("myuser","mypass".toCharArray());
}});
HttpURLConnection c = (HttpURLConnection) new URL(url).openConnection();
c.setUseCaches(false);
c.connect();
Obviously your getPasswordAuthentication() should probably do something more intelligent than returning a constant.
If you're trying to make a request with a body (e.g. POST
) with authentication, beware of Android issue 4326. I've linked a suggested fix to the platform there, but there's a simple workaround if you only want Basic auth: don't bother with Authenticator, and instead do this:
c.setRequestProperty("Authorization", "basic " +
Base64.encode("myuser:mypass".getBytes(), Base64.NO_WRAP));
This will do the same as many of the other answers, but will make sides flush with the window, so there is no scroll bars.

I wasn't sure what you were trying to do with the index information based on the question. However, in C#, you can usually adapt the IEnumerable.Select method to get the index out of whatever you want. For instance, I might use something like this for whether a value is odd or even.
string[] names = { "one", "two", "three" };
var oddOrEvenByName = names
.Select((name, index) => new KeyValuePair<string, int>(name, index % 2))
.ToDictionary(kvp => kvp.Key, kvp => kvp.Value);
This would give you a dictionary by name of whether the item was odd (1) or even (0) in the list.
As mentioned in other answers, doubles can have small deviations. And you could write your own method to compare them using an "acceptable" deviation. However ...
There is an apache class for comparing doubles: org.apache.commons.math3.util.Precision
It contains some interesting constants: SAFE_MIN
and EPSILON
, which are the maximum possible deviations of simple arithmetic operations.
It also provides the necessary methods to compare, equal or round doubles. (using ulps or absolute deviation)
As @Hellfrost pointed out, it is literally nonsense to compare a number to two different numbers in "one operation", and I know of no C# operator that encapsulates this.
between = (0 < 5 && 5 < 10);
Is about the most-compact form I can think of.
You could make a somewhat "fluent"-looking method using extension (though, while amusing, I think it's overkill):
public static bool Between(this int x, int a, int b)
{
return (a < x) && (x < b);
}
Use:
int x = 5;
bool b = x.Between(0,10);
We had this issue as the host server had been updated to use TLS V1.2 and we were connecting using standard SSL. This was an update made as part of pen testing of the sites. We saw the issue in code connection, but not browsers going to the wsdl. Below code resolved:
if (System.Net.ServicePointManager.SecurityProtocol == (SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls))
System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;
Taken from here: How do I disable SSL fallback and use only TLS for outbound connections in .NET? (Poodle mitigation)
There is an important technical difference between race conditions and data races. Most answers seem to make the assumption that these terms are equivalent, but they are not.
A data race occurs when 2 instructions access the same memory location, at least one of these accesses is a write and there is no happens before ordering among these accesses. Now what constitutes a happens before ordering is subject to a lot of debate, but in general ulock-lock pairs on the same lock variable and wait-signal pairs on the same condition variable induce a happens-before order.
A race condition is a semantic error. It is a flaw that occurs in the timing or the ordering of events that leads to erroneous program behavior.
Many race conditions can be (and in fact are) caused by data races, but this is not necessary. As a matter of fact, data races and race conditions are neither the necessary, nor the sufficient condition for one another. This blog post also explains the difference very well, with a simple bank transaction example. Here is another simple example that explains the difference.
Now that we nailed down the terminology, let us try to answer the original question.
Given that race conditions are semantic bugs, there is no general way of detecting them. This is because there is no way of having an automated oracle that can distinguish correct vs. incorrect program behavior in the general case. Race detection is an undecidable problem.
On the other hand, data races have a precise definition that does not necessarily relate to correctness, and therefore one can detect them. There are many flavors of data race detectors (static/dynamic data race detection, lockset-based data race detection, happens-before based data race detection, hybrid data race detection). A state of the art dynamic data race detector is ThreadSanitizer which works very well in practice.
Handling data races in general requires some programming discipline to induce happens-before edges between accesses to shared data (either during development, or once they are detected using the above mentioned tools). this can be done through locks, condition variables, semaphores, etc. However, one can also employ different programming paradigms like message passing (instead of shared memory) that avoid data races by construction.
They can be considered as equivalent. The limits in size are the same:
There is also the DBCLOBs, for double byte characters.

Here is the Swift 3 answer for anyone looking since Swift 3 does not accept "Make".
aView.center = CGPoint(x: 200, Y: 200)
It depends on what you mean by "multiple lines". Different operating systems use different line separators.
In Java, \r
is always carriage return, and \n
is line feed. On Unix, just \n
is enough for a newline, whereas many programs on Windows require \r\n
. You can get at the platform default newline use System.getProperty("line.separator")
or use String.format("%n")
as mentioned in other answers.
But really, you need to know whether you're trying to produce OS-specific newlines - for example, if this is text which is going to be transmitted as part of a specific protocol, then you should see what that protocol deems to be a newline. For example, RFC 2822 defines a line separator of \r\n
and this should be used even if you're running on Unix. So it's all about context.
This is all you have to do:
In front.inc
global $name;
$name = 'james';
extensionsToCheck = ('.pdf', '.doc', '.xls')
'test.doc'.endswith(extensionsToCheck) # returns True
'test.jpg'.endswith(extensionsToCheck) # returns False
data_initial = open("staff.csv", "rb")
data = csv.reader((line.replace('\0','') for line in data_initial), delimiter=",")
This works for me.

To Wrap things up . I think most of the people which came here like me want the simplest solution possible without using any libraries and with best possible performance.
(The accepted group by method for me i think is an overkill in terms of performance. )
Here is a simple extension method using the IEqualityComparer interface which works also for null values.
Usage:
var filtered = taskList.DistinctBy(t => t.TaskExternalId).ToArray();
Extension Method Code
public static class LinqExtensions
{
public static IEnumerable<T> DistinctBy<T, TKey>(this IEnumerable<T> items, Func<T, TKey> property)
{
GeneralPropertyComparer<T, TKey> comparer = new GeneralPropertyComparer<T,TKey>(property);
return items.Distinct(comparer);
}
}
public class GeneralPropertyComparer<T,TKey> : IEqualityComparer<T>
{
private Func<T, TKey> expr { get; set; }
public GeneralPropertyComparer (Func<T, TKey> expr)
{
this.expr = expr;
}
public bool Equals(T left, T right)
{
var leftProp = expr.Invoke(left);
var rightProp = expr.Invoke(right);
if (leftProp == null && rightProp == null)
return true;
else if (leftProp == null ^ rightProp == null)
return false;
else
return leftProp.Equals(rightProp);
}
public int GetHashCode(T obj)
{
var prop = expr.Invoke(obj);
return (prop==null)? 0:prop.GetHashCode();
}
}
When using NOT IN, you should also consider NOT EXISTS, which handles the null cases silently. See also PostgreSQL Wiki
SELECT mac, creation_date
FROM logs lo
WHERE logs_type_id=11
AND NOT EXISTS (
SELECT *
FROM consols nx
WHERE nx.mac = lo.mac
);
With MySQL 5.x you can use:
ALTER TABLE table_name
CHANGE COLUMN old_column_name new_column_name DATATYPE NULL DEFAULT NULL;
If you have to test more than one string in the same validation, you can do something like this:
import java.util.Optional;
import java.util.function.Predicate;
import java.util.stream.Stream;
public class StringHelper {
public static Boolean hasBlank(String ... strings) {
Predicate<String> isBlank = s -> s == null || s.trim().isEmpty();
return Optional
.ofNullable(strings)
.map(Stream::of)
.map(stream -> stream.anyMatch(isBlank))
.orElse(false);
}
}
So, you can use this like StringHelper.hasBlank("Hello", null, "", " ")
or StringHelper.hasBlank("Hello")
in a generic form.
Rather than doing string manipulation, you can use the HOUR, MINUTE, SECOND functions to break apart the time. You can then multiply by 60*60*1000, 60*1000, and 1000 respectively to get milliseconds.
Let me guess
Your initial declaration of class PUBLICClass
was not public, then you made it `Public', can you try to clean and rebuild your project ?
Another way to avoid this problem that may help others is build your .net web service to version 4.0 or higher if possible.
You can always use an attribute selector. The selector itself would look something like:
a[data-item-id=stand-out]
MySQL ODBC 3.51 Driver is that special characters in the password aren't handled.
"Warning – You might have a serious headache with MySQL ODBC 3.51 if the password in your GRANT command contains special characters, such as ! @ # $ % ^ ?. MySQL ODBC 3.51 ODBC Driver does not support these special characters in the password box. The only error message you would receive is “Access denied” (using password: YES)" - from http://www.plaintutorials.com/install-and-create-mysql-odbc-connector-on-windows-7/
Content insets solve the problem of having content that goes underneath other parts of the User Interface and yet still remains reachable using scroll bars. In other words, the purpose of the Content Inset is to make the interaction area smaller than its actual area.
Consider the case where we have three logical areas of the screen:
TOP BUTTONS
TEXT
BOTTOM TAB BAR
and we want the TEXT to never appear transparently underneath the TOP BUTTONS, but we want the Text to appear underneath the BOTTOM TAB BAR and yet still allow scrolling so we could update the text sitting transparently under the BOTTOM TAB BAR.
Then we would set the top origin to be below the TOP BUTTONS, and the height to include the bottom of BOTTOM TAB BAR. To gain access to the Text sitting underneath the BOTTOM TAB BAR content we would set the bottom inset to be the height of the BOTTOM TAB BAR.
Without the inset, the scroller would not let you scroll up the content enough to type into it. With the inset, it is as if the content had extra "BLANK CONTENT" the size of the content inset. Blank text has been "inset" into the real "content" -- that's how I remember the concept.
To add a star use the Unicode character 22C6
.
I added a space to make a little gap between the li
and the star. The code for space is A0
.
li:before {
content: '\22C6\A0';
}
Wait
and await
- while similar conceptually - are actually completely different.
Wait
will synchronously block until the task completes. So the current thread is literally blocked waiting for the task to complete. As a general rule, you should use "async
all the way down"; that is, don't block on async
code. On my blog, I go into the details of how blocking in asynchronous code causes deadlock.
await
will asynchronously wait until the task completes. This means the current method is "paused" (its state is captured) and the method returns an incomplete task to its caller. Later, when the await
expression completes, the remainder of the method is scheduled as a continuation.
You also mentioned a "cooperative block", by which I assume you mean a task that you're Wait
ing on may execute on the waiting thread. There are situations where this can happen, but it's an optimization. There are many situations where it can't happen, like if the task is for another scheduler, or if it's already started or if it's a non-code task (such as in your code example: Wait
cannot execute the Delay
task inline because there's no code for it).
You may find my async
/ await
intro helpful.
I wanted to add something new because of the following:
At a first attemp I failed to beat
std::ostringstream
's operator<<
efficiency, but with more attemps I was able to make a StringBuilder that is faster in some cases.
Everytime I append a string I just store a reference to it somewhere and increase the counter of the total size.
The real way I finally implemented it (Horror!) is to use a opaque buffer(std::vector < char > ):
for byte [ ]
for moved strings (strings appended with std::move
)
std::string
object (we have ownership)for strings
std::string
object (no ownership)There's also one small optimization, if last inserted string was mov'd in, it checks for free reserved but unused bytes and store further bytes in there instead of using the opaque buffer (this is to save some memory, it actually make it slightly slower, maybe depend also on the CPU, and it is rare to see strings with extra reserved space anyway)
This was finally slightly faster than std::ostringstream
but it has few downsides:
ostringstream
conclusion? use
std::ostringstream
It already fix the biggest bottleneck while ganing few % points in speed with mine implementation is not worth the downsides.

If you like to do this for open files on Notepad++, you can use Combine plugin: http://www.scout-soft.com/combine/
The text inside $type is substituted directly into the insert string, therefore MySQL gets this:
... VALUES(testing, 'john', 'whatever')
Notice that there are no quotes around testing, you need to put these in like so:
$type = 'testing';
mysql_query("INSERT INTO contents (type, reporter, description) VALUES('$type', 'john', 'whatever')");
I also recommend you read up on SQL injection, as this sort of parameter passing is prone to hacking attempts if you do not sanitize the data being used:
I think is good enough. It's clear, it lazy so it will be fast (except maybe the first case when you split the string).
Not that I did anything wrong, but I ran into this issue for a completely different reason and kinda know what caused this.
I previously used finder and dragged a file into my project's directory/folder. I didn't drag into Xcode. To make Xcode include that file into the project, I had to drag it into Xcode myself later again.
But when I switched to a new branch which didn't have that file (nor it needed to), Xcode was giving me this error:
Build input file cannot be found: '/Users/honey/Documents/xp/xpios/powerup/Models Extensions/CGSize+Extension.swift'
I did clean build folder and delete my derived data, but it didn't work until I restarted my Xcode.
You want to do this - set a function that will be executed to respond to the onclick event:
document.getElementById('buttonLED'+id).onclick = function(){ writeLED(1,1); } ;
The things you are doing don't work because:
The onclick event handler expects to have a function, here you are assigning a string
document.getElementById('buttonLED'+id).onclick = "writeLED(1,1)";
In this, you are assigning as the onclick event handler the result of executing the writeLED(1,1) function:
document.getElementById('buttonLED'+id).onclick = writeLED(1,1);
You need to change:
{% endblock content %}
to
{% endblock %}
I liked fab's answer but didn't want to use a dictionary for my situation so I substituted a list of tuples.
// set up your data
public static List<Tuple<string, string>> List = new List<Tuple<string, string>>
{
new Tuple<string, string>("Item1", "Item2")
}
// bind to the combo box
comboBox.DataSource = new BindingSource(List, null);
comboBox.ValueMember = "Item1";
comboBox.DisplayMember = "Item2";
//Get selected value
string value = ((Tuple<string, string>)queryList.SelectedItem).Item1;
function getURLParameter(name) {
return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search) || [null, ''])[1].replace(/\+/g, '%20')) || null;
}
So you can use:
myvar = getURLParameter('myvar');
If the file contains only parameter assignments, you can use the following loop in place of sourcing it:
# Instead of source file.txt
while IFS="=" read name value; do
declare "$name=$value"
done < file.txt
This saves you having to quote anything in the file, and is also more secure, as you don't risk executing arbitrary code from file.txt
.

After you instansiated the map object (from the fragment) add this -
private void centerMapOnMyLocation() {
map.setMyLocationEnabled(true);
location = map.getMyLocation();
if (location != null) {
myLocation = new LatLng(location.getLatitude(),
location.getLongitude());
}
map.animateCamera(CameraUpdateFactory.newLatLngZoom(myLocation,
Constants.MAP_ZOOM));
}
if you need any guidance just ask but it should be self explantory - just instansiate the myLocation object for a default one...

This is a function snippet I wrote to scan the user input for a string and then store that string on an array of the same size as the user input. Note that I initialize j to the value of 2 to be able to store the '\0' character.
char* dynamicstring() {
char *str = NULL;
int i = 0, j = 2, c;
str = (char*)malloc(sizeof(char));
//error checking
if (str == NULL) {
printf("Error allocating memory\n");
exit(EXIT_FAILURE);
}
while((c = getc(stdin)) && c != '\n')
{
str[i] = c;
str = realloc(str,j*sizeof(char));
//error checking
if (str == NULL) {
printf("Error allocating memory\n");
free(str);
exit(EXIT_FAILURE);
}
i++;
j++;
}
str[i] = '\0';
return str;
}
In main(), you can declare another char* variable to store the return value of dynamicstring() and then free that char* variable when you're done using it.
__init__

alter table tablename drop (column1, column2, column3......);
The initial source cause can also be an out of memory.
let suppose we create a table Transactions using SQl server management studio
txn_id int,
txn_type_id varchar(200),
Account_id int,
Amount int,
tDate date
);
with date datatype we can insert values in simple format: 'yyyy-mm-dd'
INSERT INTO transactions (txn_id,txn_type_id,Account_id,Amount,tDate)
VALUES (978, 'DBT', 103, 100, '2004-01-22');
Moreover we can have differet time formats like
DATE - format YYYY-MM-DD
DATETIME - format: YYYY-MM-DD HH:MI:SS
SMALLDATETIME - format: YYYY-MM-DD HH:MI:SS
Summary,
Code solution: Here
Configuration solutions: Here
With the help of Mike Chaliy, I found some solutions on how to do this through code. Because this issue is going to affect pretty much all projects we deploy to a live environment I held out for a purely configuration solution. I eventually found one which details how to do it in .net 3.0 and .net 3.5.
Taken from the site, below is an example of how to alter your applications web config:
<system.serviceModel>
<serviceHostingEnvironment>
<baseAddressPrefixFilters>
<add prefix="net.tcp://payroll.myorg.com:8000"/>
<add prefix="http://shipping.myorg.com:9000"/>
</baseAddressPrefixFilters>
</serviceHostingEnvironment>
</system.serviceModel>
In the above example, net.tcp://payroll.myorg.com:8000 and http://shipping.myorg.com:9000 are the only base addresses, for their respective schemes, which will be allowed to be passed through. The baseAddressPrefixFilter does not support any wildcards .
The baseAddresses supplied by IIS may have addresses bound to other schemes not present in baseAddressPrefixFilter list. These addresses will not be filtered out.
Dns solution (untested): I think that if you created a new dns entry specific to your web application, added a new web site, and gave it a single host header matching the dns entry, you would mitigate this issue altogether, and would not have to write custom code or add prefixes to your web.config file.
The "Postman - REST Client" is not suitable for doing post action with setting content-type.You can try to use "Advanced REST client" or others.
Additionally, headers was replace by consumes and produces since Spring 3.1 M2, see https://spring.io/blog/2011/06/13/spring-3-1-m2-spring-mvc-enhancements. And you can directly use produces = MediaType.MULTIPART_FORM_DATA_VALUE
.
as noted here, this is what worked best for me:
sudo apt-get install python3 python3-pip python3-setuptools
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 10
xrange from Python 2 is a generator and implements iterator while range is just a function. In Python3 I don't know why was dropped off the xrange.

You can use the deprecated AppDomain.GetCurrentThreadId
to get the ID of the currently running thread. This method uses a PInvoke to the Win32 API method GetCurrentThreadID
, and will return the Windows thread ID.
This method is marked as deprecated because the .NET Thread object does not correspond to a single Windows thread, and as such there is no stable ID which can be returned by Windows for a given .NET thread.
See configurator's answer for more reasons why this is the case.
The delete
operator deallocates memory and calls the destructor for a single object created with new
.
The delete []
operator deallocates memory and calls destructors for an array of objects created with new []
.
Using delete
on a pointer returned by new []
or delete []
on a pointer returned by new
results in undefined behavior.
Because you have to have an index on a foreign key field you can just create a simple index on the field 'AID'
CREATE INDEX aid_index ON mytable (AID);
and only then drop the unique index 'AID'
ALTER TABLE mytable DROP INDEX AID;
os.pardir
is a better way for ../
and more readable.
import os
print os.path.abspath(os.path.join(given_path, os.pardir))
This will return the parent path of the given_path
In the constructor method of your model class set the default value whatever you want. Then in your first action create an instance of the model and pass it to your view.
public ActionResult VolunteersAdd()
{
VolunteerModel model = new VolunteerModel(); //to set the default values
return View(model);
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult VolunteersAdd(VolunteerModel model)
{
return View(model);
}
The layout is extremely inefficient and bloated. You don't need that many LinearLayout
s. In fact you don't need any LinearLayout
at all.
Use only one RelativeLayout
. Like this.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ImageButton android:background="@null"
android:id="@+id/back"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/back"
android:padding="10dip"
android:layout_alignParentLeft="true"/>
<ImageButton android:background="@null"
android:id="@+id/forward"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/forward"
android:padding="10dip"
android:layout_toRightOf="@id/back"/>
<ImageButton android:background="@null"
android:id="@+id/special"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/barcode"
android:padding="10dip"
android:layout_alignParentRight="true"/>
</RelativeLayout>
The patch is here: https://code.ros.org/trac/opencv/attachment/ticket/862/OpenCV-2.2-nov4l1.patch
By adding #ifdef HAVE_CAMV4L
around
#include <linux/videodev.h>
in OpenCV-2.2.0/modules/highgui/src/cap_v4l.cpp
and removing || defined (HAVE_CAMV4L2)
from line 174
allowed me to compile.
You can use string.punctuation
and any
function like this
import string
invalidChars = set(string.punctuation.replace("_", ""))
if any(char in invalidChars for char in word):
print "Invalid"
else:
print "Valid"
With this line
invalidChars = set(string.punctuation.replace("_", ""))
we are preparing a list of punctuation characters which are not allowed. As you want _
to be allowed, we are removing _
from the list and preparing new set as invalidChars
. Because lookups are faster in sets.
any
function will return True
if atleast one of the characters is in invalidChars
.
Edit: As asked in the comments, this is the regular expression solution. Regular expression taken from https://stackoverflow.com/a/336220/1903116
word = "Welcome"
import re
print "Valid" if re.match("^[a-zA-Z0-9_]*$", word) else "Invalid"
Here is the latest sample of Google's geocode Web Service
https://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&key=YOUR_API_KEY

to the API key you get from Google Geocoding API
P/S: Geocoding API is under Places NOT Maps ;)
According to the documentation, timestamp
is a synonym for rowversion
- it's automatically generated and guaranteed1 to be unique. datetime
isn't - it's just a data type which handles dates and times, and can be client-specified on insert etc.

I just found 0(zero) and shift+0 works on vim.

Disabling and Enabling All Foreign Keys
CREATE PROCEDURE pr_Disable_Triggers_v2
@disable BIT = 1
AS
DECLARE @sql VARCHAR(500)
, @tableName VARCHAR(128)
, @tableSchema VARCHAR(128)
-- List of all tables
DECLARE triggerCursor CURSOR FOR
SELECT t.TABLE_NAME AS TableName
, t.TABLE_SCHEMA AS TableSchema
FROM INFORMATION_SCHEMA.TABLES t
ORDER BY t.TABLE_NAME, t.TABLE_SCHEMA
OPEN triggerCursor
FETCH NEXT FROM triggerCursor INTO @tableName, @tableSchema
WHILE ( @@FETCH_STATUS = 0 )
BEGIN
SET @sql = 'ALTER TABLE ' + @tableSchema + '.[' + @tableName + '] '
IF @disable = 1
SET @sql = @sql + ' DISABLE TRIGGER ALL'
ELSE
SET @sql = @sql + ' ENABLE TRIGGER ALL'
PRINT 'Executing Statement - ' + @sql
EXECUTE ( @sql )
FETCH NEXT FROM triggerCursor INTO @tableName, @tableSchema
END
CLOSE triggerCursor
DEALLOCATE triggerCursor
First, the foreignKeyCursor cursor is declared as the SELECT statement that gathers the list of foreign keys and their table names. Next, the cursor is opened and the initial FETCH statement is executed. This FETCH statement will read the first row's data into the local variables @foreignKeyName and @tableName. When looping through a cursor, you can check the @@FETCH_STATUS for a value of 0, which indicates that the fetch was successful. This means the loop will continue to move forward so it can get each successive foreign key from the rowset. @@FETCH_STATUS is available to all cursors on the connection. So if you are looping through multiple cursors, it is important to check the value of @@FETCH_STATUS in the statement immediately following the FETCH statement. @@FETCH_STATUS will reflect the status for the most recent FETCH operation on the connection. Valid values for @@FETCH_STATUS are:
0 = FETCH was successful
-1 = FETCH was unsuccessful
-2 = the row that was fetched is missingInside the loop, the code builds the ALTER TABLE command differently depending on whether the intention is to disable or enable the foreign key constraint (using the CHECK or NOCHECK keyword). The statement is then printed as a message so its progress can be observed and then the statement is executed. Finally, when all rows have been iterated through, the stored procedure closes and deallocates the cursor.
I have added a line in list item like below
<View
android:id="@+id/divider"
android:layout_width="match_parent"
android:layout_height="1px"
android:background="@color/dividerColor"/>
1px will draw the thin line.
If you want to hide the divider for the last row then
divider.setVisiblity(View.GONE);
on the onBindViewHolder for the last list Item.

When you work with unsigned types, modular arithmetic (also known as "wrap around" behavior) is taking place. To understand this modular arithmetic, just have a look at these clocks:
9 + 4 = 1 (13 mod 12), so to the other direction it is: 1 - 4 = 9 (-3 mod 12). The same principle is applied while working with unsigned types. If the result type is unsigned
, then modular arithmetic takes place.
Now look at the following operations storing the result as an unsigned int
:
unsigned int five = 5, seven = 7;
unsigned int a = five - seven; // a = (-2 % 2^32) = 4294967294
int one = 1, six = 6;
unsigned int b = one - six; // b = (-5 % 2^32) = 4294967291
When you want to make sure that the result is signed
, then stored it into signed
variable or cast it to signed
. When you want to get the difference between numbers and make sure that the modular arithmetic will not be applied, then you should consider using abs()
function defined in stdlib.h
:
int c = five - seven; // c = -2
int d = abs(five - seven); // d = 2
Be very careful, especially while writing conditions, because:
if (abs(five - seven) < seven) // = if (2 < 7)
// ...
if (five - seven < -1) // = if (-2 < -1)
// ...
if (one - six < 1) // = if (-5 < 1)
// ...
if ((int)(five - seven) < 1) // = if (-2 < 1)
// ...
but
if (five - seven < 1) // = if ((unsigned int)-2 < 1) = if (4294967294 < 1)
// ...
if (one - six < five) // = if ((unsigned int)-5 < 5) = if (4294967291 < 5)
// ...
Every time I go from heavy C++ coding to Java, it takes me a little while to adapt to the lack of const-correctness in Java. This usage of const
in C++ is much different than just declaring constant variables, if you didn't know. Essentially, it ensures that an object is immutable when accessed through a special kind of pointer called a const-pointer When in Java, in places where I'd normally want to return a const-pointer, I instead return a reference with an interface type containing only methods that shouldn't have side effects. Unfortunately, this isn't enforced by the langauge.
Wikipedia offers the following information on the subject:
Interestingly, the Java language specification regards const as a reserved keyword — i.e., one that cannot be used as variable identifier — but assigns no semantics to it. It is thought that the reservation of the keyword occurred to allow for an extension of the Java language to include C++-style const methods and pointer to const type. The enhancement request ticket in the Java Community Process for implementing const correctness in Java was closed in 2005, implying that const correctness will probably never find its way into the official Java specification.

You can also remove files from the repository based on your .gitignore without deleting them from the local file system :
git rm --cached `git ls-files -i -X .gitignore`
Or, alternatively, on Windows Powershell:
git rm --cached $(git ls-files -i -X .gitignore)
Great news, the fix is coming in March 2018, see this link: https://developers.google.com/web/updates/2018/01/devtools
"Local Overrides let you make changes in DevTools, and keep those changes across page loads. Previously, any changes that you made in DevTools would be lost when you reloaded the page. Local Overrides work for most file types
How it works:
To set up Local Overrides:
UPDATE (March 19, 2018): It's live, detailed explanations here: https://developers.google.com/web/updates/2018/01/devtools#overrides
Push object into your array. Try this:
export class FormComponent implements OnInit {
name: string;
empoloyeeID : number;
empList: Array<{name: string, empoloyeeID: number}> = [];
constructor() {}
ngOnInit() {}
onEmpCreate(){
console.log(this.name,this.empoloyeeID);
this.empList.push({ name: this.name, empoloyeeID: this.empoloyeeID });
this.name = "";
this.empoloyeeID = 0;
}
}
As a workaround I've been returning the last object in the array that you get back from the function... It is not a great solution, but it's better than nothing:
someFunction {
$a = "hello"
"Function is running"
return $a
}
$b = someFunction
$b = $b[($b.count - 1)] # Or
$b = $b[-1] # Simpler
All in all, a more one-lineish way of writing the same thing could be:
$b = (someFunction $someParameter $andAnotherOne)[-1]
Just set display:none;
as an attribute in your stylesheet ;)
It's way better than loading pictures for nothing.
body::-webkit-scrollbar {
width: 9px;
height: 9px;
}
body::-webkit-scrollbar-button:start:decrement,
body::-webkit-scrollbar-button:end:increment {
display: block;
height: 0;
background-color: transparent;
}
body::-webkit-scrollbar-track-piece {
background-color: #ffffff;
opacity: 0.2;
/* Here */
display: none;
-webkit-border-radius: 0;
-webkit-border-bottom-right-radius: 14px;
-webkit-border-bottom-left-radius: 14px;
}
body::-webkit-scrollbar-thumb:vertical {
height: 50px;
background-color: #333333;
-webkit-border-radius: 8px;
}
You can just type these 3 commands from command prompt:
start
start cmd
start cmd.exe
I got around this by upgrading both the version of Angular that I was using (from v8 -> v9) and the version of TypeScript (from 3.5.3 -> latest).
One thing I wanted to add since I just ran into this, if you are trying to getActionBar() on an Activity that has a parent, it will return null. I am trying to refactor code where my Activity is contained inside an ActivityGroup, and it took a good few minutes for me to go "oh duh" after looking at the source of how an ActionBar gets created in source.
http://example.com/ may resolve to a different VirtualHost than https://example.com/ (which, as the Host header is not sent, responds to the default for that IP), so the two are treated as separate domains and thus subject to crossdomain JS restrictions.
JSON callbacks may let you avoid this.
You're half way there on your own. To implement a refresh, you'd just wrap what you already have in a function on the scope:
function PersonListCtrl($scope, $http) {
$scope.loadData = function () {
$http.get('/persons').success(function(data) {
$scope.persons = data;
});
};
//initial load
$scope.loadData();
}
then in your markup
<div ng-controller="PersonListCtrl">
<ul>
<li ng-repeat="person in persons">
Name: {{person.name}}, Age {{person.age}}
</li>
</ul>
<button ng-click="loadData()">Refresh</button>
</div>
As far as "accessing your model", all you'd need to do is access that $scope.persons array in your controller:
for example (just puedo code) in your controller:
$scope.addPerson = function() {
$scope.persons.push({ name: 'Test Monkey' });
};
Then you could use that in your view or whatever you'd want to do.
You need to use the reserve function to set an initial allocated size or do it in the initial constructor.
vector<CustomClass *> content(20000);
or
vector<CustomClass *> content;
...
content.reserve(20000);
When you reserve()
elements, the vector
will allocate enough space for (at least?) that many elements. The elements do not exist in the vector
, but the memory is ready to be used. This will then possibly speed up push_back()
because the memory is already allocated.
Follow the next steps:
import java.util.*;
public class matrixcecil {
public static void main(String args[]){
List<Integer> k1=new ArrayList<Integer>(10);
k1.add(23);
k1.add(10);
k1.add(20);
k1.add(24);
int i=0;
while(k1.size()<10){
if(i==(k1.get(k1.size()-1))){
}
i=k1.get(k1.size()-1);
k1.add(30);
i++;
break;
}
System.out.println(k1);
}
}
I think this example will help you for better solution.
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.
You need to call $compile
on the HTML string before inserting it into the DOM so that angular gets a chance to perform the binding.
In your fiddle, it would look something like this.
$("#dynamicContent").html(
$compile(
"<button ng-click='count = count + 1' ng-init='count=0'>Increment</button><span>count: {{count}} </span>"
)(scope)
);
Obviously, $compile
must be injected into your controller for this to work.
Read more in the $compile
documentation.
You need to cleanup your tortoise SVN by clicking on cleanup option you get after Right Clicking on windows where you want to UPDATE SVN. And after cleanup try updating SVN similarly by clicking UPDATE SVN option you get after right clicking.
This worked for me.
You use it like this:
SELECT age, name
FROM users
UNION
SELECT 25 AS age, 'Betty' AS name
Use UNION ALL
to allow duplicates: if there is a 25-years old Betty among your users, the second query will not select her again with mere UNION
.
there's nothing wrong with using CHAR like that..
I think your problem is that you have a space in your tablename. It should be: charteredflight
or chartered_flight
..
You can use the nice_hash gem: https://github.com/MarioRuiz/nice_hash
require 'nice_hash'
my_string = '{"val":"test","val1":"test1","val2":"test2"}'
# on my_hash will have the json as a hash, even when nested with arrays
my_hash = my_string.json
# you can filter and get what you want even when nested with arrays
vals = my_string.json(:val1, :val2)
# even you can access the keys like this:
puts my_hash._val1
puts my_hash.val1
puts my_hash[:val1]
Simply Abstract Data Type is nothing but a set of operation and set of data is used for storing some other data efficiently in the machine. There is no need of any perticular type declaration. It just require a implementation of ADT.
If you want to change tabs to spaces in a lot of files, but don't want to open them individually, I have found that it works equally as well to just use the Find and Replace option from the left-most tools bar.
In the first box (Find
), copy and paste a tab from the source code.
In the second box (Replace
), enter the number of spaces that you wish to use (i.e. 2 or 4).
If you press the ...
button, you can specify directories to include or ignore (i.e. src/Data/Json
).
Finally, inspect the result preview and press Replace All. All files in the workspace may be affected.
Have you considered using css3 media queries? In most cases you can apply some css styles specifically for the targeted device without having to create a separate mobile version of the site.
@media screen and (max-width:1025px) {
#content {
width: 100%;
}
}
You can set the width to whatever you want, but 1025 will catch the iPad landscape view.
You'll also want to add the following meta tag to your head:
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
Check out this article over at HTML5 Rocks for some good examples
=begin
(some code here)
=end
and
# This code
# on multiple lines
# is commented out
are both correct. The advantage of the first type of comment is editability—it's easier to uncomment because fewer characters are deleted. The advantage of the second type of comment is readability—reading the code line by line, it's much easier to tell that a particular line has been commented out. Your call but think about who's coming after you and how easy it is for them to read and maintain.
Sometimes you can achieve the same result by playing only with padding OR margin. Example :
Say View X contains view Y (aka : View Y is inside View X).
-View Y with Margin=30 OR View X with Padding=30 will achieve the same result: View Y will have an offset of 30.
You can sort the array first, and then loop through it twice, once in both directions:
Arrays.sort(arr);
System.out.print("Numbers in Ascending Order:" );
for(int i = 0; i < arr.length; i++){
System.out.print( " " + arr[i]);
}
System.out.print("Numbers in Descending Order: " );
for(int i = arr.length - 1; i >= 0; i--){
System.out.print( " " + arr[i]);
}
You can use the sequence method list.extend
to extend the list by multiple values from any kind of iterable, being it another list or any other thing that provides a sequence of values.
>>> lst = [1, 2]
>>> lst.append(3)
>>> lst.append(4)
>>> lst
[1, 2, 3, 4]
>>> lst.extend([5, 6, 7])
>>> lst.extend((8, 9, 10))
>>> lst
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
>>> lst.extend(range(11, 14))
>>> lst
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]
So you can use list.append()
to append a single value, and list.extend()
to append multiple values.
Now you want to do from binary string to Decimal but Afterword, You might be needed contrary method. It's down below.
public static String decimalToBinaryString(int value) {
String str = "";
while(value > 0) {
if(value % 2 == 1) {
str = "1"+str;
} else {
str = "0"+str;
}
value /= 2;
}
return str;

Windows 7 64-bit, with both Python3.4 and Python2.7 installed at some point :)
I'm using Py.exe to route to Py2 or Py3 depending on the script's needs - but I previously improperly uninstalled Python27 before.
Py27 was removed manually from C:\python\Python27 (the folder Python27 was deleted by me previously)
Upon re-installing Python27, it gave the above error you specify.
It would always back out while trying to 'remove shortcuts' during the installation process.
I placed a copy of Python27 back in that original folder, at C:\Python\Python27, and re-ran the same failing Python27 installer. It was happy locating those items and removing them, and proceeded with the install.
This is not the answer that addresses registry key issues (others mention that) but it is somewhat of a workaround if you know of previous installations that were improperly removed.
You could have some insight to this by opening "regedit" and searching for "Python27" - a registry key appeared in my command-shell Cache pointing at c:\python\python27\ (which had been removed and was not present when searching in the registry upon finding it).
That may help point to previously improperly removed installations.
Good luck!
I faced this issue today, and I resolved it by doing the following steps:
1) manually inserting that troubling user providing value of mandatory fields into mysql.user

3) A.
mysql> drop user jack;
Query OK, 0 rows affected (0.00 sec)
B. mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
C. mysql> create user 'jack' identified by 'jack';
Query OK, 0 rows affected (0.00 sec)
D. mysql> select Host, User, Password, ssl_type from user where User = 'jack';

The following query can be used to detemine tablespace and other params:
select df.tablespace_name "Tablespace",
totalusedspace "Used MB",
(df.totalspace - tu.totalusedspace) "Free MB",
df.totalspace "Total MB",
round(100 * ( (df.totalspace - tu.totalusedspace)/ df.totalspace)) "Pct. Free"
from (select tablespace_name,
round(sum(bytes) / 1048576) TotalSpace
from dba_data_files
group by tablespace_name) df,
(select round(sum(bytes)/(1024*1024)) totalusedspace,
tablespace_name
from dba_segments
group by tablespace_name) tu
where df.tablespace_name = tu.tablespace_name
and df.totalspace <> 0;
Source: https://community.oracle.com/message/1832920
For your case if you want to know the partition name and it's size just run this query:
select owner,
segment_name,
partition_name,
segment_type,
bytes / 1024/1024 "MB"
from dba_segments
where owner = <owner_name>;
body{
margin:0;

}
@media screen{
body>div#header{
position: fixed;
}
}
* html body{
overflow:hidden;
}
* html div#content{
height:100%;
overflow:auto;
}
In addition to Christopher's answer.
If you need to count total size of versioned bucket use:
aws s3api list-object-versions --bucket BUCKETNAME --output json --query "[sum(Versions[].Size)]"
It counts both Latest and Archived versions.
Another solution possible to this error is check your Java version, maybe you can solve it downloading this jdk oracle-jdk-8, this was my mistake :P
in angular2 2.1.1 I was not able to catch the exception using the (data),(error) pattern, so I implemented it using .catch(...).
It's nice because it can be used with all other Observable chained methods like .retry .map etc.
import {Observable} from 'rxjs/Rx';
Http
.put(...)
.catch(err => {
notify('UI error handling');
return Observable.throw(err); // observable needs to be returned or exception raised
})
.subscribe(data => ...) // handle success
from documentation:
Returns
(Observable): An observable sequence containing elements from consecutive source sequences until a source sequence terminates successfully.
In your Request class (that extends Request), override the getParams() method. You would do the same for headers, just override getHeaders().
If you look at PostWithBody class in TestRequest.java in Volley tests, you'll find an example. It goes something like this
public class LoginRequest extends Request<String> {
// ... other methods go here
private Map<String, String> mParams;
public LoginRequest(String param1, String param2, Listener<String> listener, ErrorListener errorListener) {
super(Method.POST, "http://test.url", errorListener);
mListener = listener;
mParams = new HashMap<String, String>();
mParams.put("paramOne", param1);
mParams.put("paramTwo", param2);
}
@Override
public Map<String, String> getParams() {
return mParams;
}
}
Evan Charlton was kind enough to make a quick example project to show us how to use volley. https://github.com/evancharlton/folly/
REST is just a software architecture style for exposing resources.
A typical REST call to return information about customer 34456 could look like:
http://example.com/customer/34456
Have a look at the IBM tutorial for REST web services
You really need to use a memory profiler that tracks allocations. Take a look at JProfiler - their "heap walker" feature is great, and they have integration with all of the major Java IDEs. It's not free, but it isn't that expensive either ($499 for a single license) - you will burn $500 worth of time pretty quickly struggling to find a leak with less sophisticated tools.
EDIT: to convert to array
int[] asIntegers = arr.Select(s => int.Parse(s)).ToArray();
This should do the trick:
var asIntegers = arr.Select(s => int.Parse(s));
def strxor (s0, s1):
l = [ chr ( ord (a) ^ ord (b) ) for a,b in zip (s0, s1) ]
return ''.join (l)
(Based on Mark Byers answer.)
I hit this issue. This architecture (from Lain's answer) worked for me. Here is the solution in Python.
Here is the main email creation function:

For Windows Forms you can control cursor position (and selection) with txtbox.SelectionStart
and txtbox.SelectionLength
properties. If you want to set caret to end try this:
txtbox.SelectionStart = txtbox.Text.Length;
txtbox.SelectionLength = 0;
For WPF see this question.
One other thing. You may need to specify the -L option as well - eg
-Wl,-rpath,/path/to/foo -L/path/to/foo -lbaz
or you may end up with an error like
ld: cannot find -lbaz
I had a similar problem, I tried to clear all the caches possible (tried almost all the solutions above) and the only thing that worked for me was to kill the expo app and to restart it.
Unfortunately, combining multiple entity contexts into a single named connection isn't possible. If you want to use named connection strings from a .config file to define your Entity Framework connections, they will each have to have a different name. By convention, that name is typically the name of the context:
<add name="ModEntity" connectionString="metadata=res://*/ModEntity.csdl|res://*/ModEntity.ssdl|res://*/ModEntity.msl;provider=System.Data.SqlClient;provider connection string="Data Source=SomeServer;Initial Catalog=SomeCatalog;Persist Security Info=True;User ID=Entity;Password=SomePassword;MultipleActiveResultSets=True"" providerName="System.Data.EntityClient" />
<add name="Entity" connectionString="metadata=res://*/Entity.csdl|res://*/Entity.ssdl|res://*/Entity.msl;provider=System.Data.SqlClient;provider connection string="Data Source=SOMESERVER;Initial Catalog=SOMECATALOG;Persist Security Info=True;User ID=Entity;Password=Entity;MultipleActiveResultSets=True"" providerName="System.Data.EntityClient" />
However, if you end up with namespace conflicts, you can use any name you want and simply pass the correct name to the context when it is generated:
var context = new Entity("EntityV2");
Obviously, this strategy works best if you are using either a factory or dependency injection to produce your contexts.
Another option would be to produce each context's entire connection string programmatically, and then pass the whole string in to the constructor (not just the name).
// Get "Data Source=SomeServer..."
var innerConnectionString = GetInnerConnectionStringFromMachinConfig();
// Build the Entity Framework connection string.
var connectionString = CreateEntityConnectionString("Entity", innerConnectionString);
var context = new EntityContext(connectionString);
How about something like this:
Type contextType = typeof(test_Entities);
string innerConnectionString = ConfigurationManager.ConnectionStrings["Inner"].ConnectionString;
string entConnection =
string.Format(
"metadata=res://*/{0}.csdl|res://*/{0}.ssdl|res://*/{0}.msl;provider=System.Data.SqlClient;provider connection string=\"{1}\"",
contextType.Name,
innerConnectionString);
object objContext = Activator.CreateInstance(contextType, entConnection);
return objContext as test_Entities;
... with the following in your machine.config:
<add name="Inner" connectionString="Data Source=SomeServer;Initial Catalog=SomeCatalog;Persist Security Info=True;User ID=Entity;Password=SomePassword;MultipleActiveResultSets=True" providerName="System.Data.SqlClient" />
This way, you can use a single connection string for every context in every project on the machine.
Here is a sample XAML
that will allow TextBox
to accept multiline text and it uses its own scrollbars:
<TextBox
Height="200"
Width="500"
TextWrapping="Wrap"
AcceptsReturn="True"
HorizontalScrollBarVisibility="Disabled"
VerticalScrollBarVisibility="Auto"/>
One way would be to serve the content as XML attributes, URL encoded strings, preformatted text with HTML encoded JSON, or data URIs, then transform it to HTML on the client. Here are a few sites which do this:
Skechers: XML
<document
filename=""
height=""
width=""
title="SKECHERS"
linkType=""
linkUrl=""
imageMap=""
href="http://www.bobsfromskechers.com"
alt="BOBS from Skechers"
title="BOBS from Skechers"
/>

Make your size a factor in your dataframe by:
temp$size_f = factor(temp$size, levels=c('50%','100%','150%','200%'))
Then change the facet_grid(.~size)
to facet_grid(.~size_f)
Then plot:
The graphs are now in the correct order.
You don't need to declare them as arrays if you want to use use them as pointers. You can simply reference pointers as if they were multi-dimensional arrays. Just create it as a pointer to a pointer and use malloc
:
int i;
int M=30, N=25;
int ** buf;
buf = (int**) malloc(M * sizeof(int*));
for(i=0;i<M;i++)
buf[i] = (int*) malloc(N * sizeof(int));
and then you can reference buf[3][5]
or whatever.
As others have noted, in general use the -v
flag for the gem install
command.
If you're developing a gem locally, after cutting a gem from your gemspec:
$ gem install gemname-version.gem
Assuming version 0.8, it would look like this:
$ gem install gemname-0.8.gem
The syntax is no longer supported in python 3. Use the following instead.
try:
do_something()
except BaseException as e:
logger.error('Failed to do something: ' + str(e))
