timeline.updateNotes = function(){
updateNotes is a function, it can not be used as ng-model
given that you are you want notes for each timeline, you can just directly call the function, why wait for change??

d9809 | train | Hole punching is what it sounds like you may need.
Add a etc/cache.xml file with a <config> root to your module. (see Enterprise/PageCache/etc/cache.xml). Choose a unique [placeholder] name.
The placeholders/[placeholder]/block node value must match the class-id of your custom dynamic block, e.g. mymodule/custom
The placeholders/[placeholder]/container node value is the class to generate the content dynamically and handle block level caching
The placeholders/[placeholder]/placeholder node value is a unique string to mark the dynamic parts in the cached page
placeholders/[placeholder]/cache_lifetime is ignored, specify a block cache lifetime in the container’s _saveCache() method if needed
Implement the container class and extends Enterprise_PageCache_Model_Container_Abstract. Use _renderBlock() to return the dynamic content.
Implement the _getCacheId() method in the container to enable the block level caching. Use cookie values instead of model ids (lower cost).
One last note: You DON’T have the full Magento App at your disposal when _renderBlock() is called. Be as conservative as possible.

d9810 | train | The MDM is supposed to handle this. You should not be required to check every request in the API to make sure it is secure. Airwatch, for instance, makes all of your applications downloadable only through their catalog and the agent or vpn system connects when the application is opened. If the user were to attempt to circumvent these limits it unenrolls their device and disallows access until a new enrollment code is issued by your tech department. | unknown | |
d9811 | train | Basically, you're constructing a programming language here (albeit simple, it's still a programming language). To interpret a programming language you need a compiler, which usually contains a lexer (which splits input stream into meaningful tokens) and a parser (which reads tokens one by one and takes whatever actions are needed). In your simplified example, the lexer would be probably regexp-based, and the parser can be a simple stack-based one.
(terms in italic should actually be wikipedia links).
A: I am not entirely sure about what your question is, but there has been a lot of debating about templating languages in PHP but I think a
general consensus reached by now was that it usually doesn't make much sense to roll
your own templating language. You might get instant nice result by e.g. using string replacement
and regular expressions, but eventually you will need more functionality like loops
or other expressions and then it will become quite tricky (ultimately ending in creating your own compiler).
The best suggestion usually is to either use PHP as your templating language directly
(that is what PHP was designed for in the first place and with strictly following the MVC pattern quite a good solution, too) or try one
of the existing templating engines. Only if you can't make any of them
fit your needs (most of them are extensible through a plugin mechanism)
you should start making your own. | unknown | |

d9817 | train | The problem you're having is because you're trying to convert a string to a currency. From MSDN:
The Currency ("C") Format Specifier
The "C" (or currency) format specifier converts a number to a string that represents a currency amount.
The .ToString(string format, IFormatProvider formatProvider) overload you're trying to use only exists for numeric types, which is why it's not compiling.
As an example to demonstrate this:
public class TestModel
{
public decimal Amount { get; set; }
public string StringAmount { get; set; }
}
class Program
{
static void Main(string[] args)
{
var model = new TestModel
{
Amount = 1.99M,
StringAmount = "1.99"
};
IFormatProvider formatProvider = new CultureInfo("en-US");
// Prints $1.99
Console.WriteLine(model.Amount.ToString("C", formatProvider));
// Prints 1.99
Console.WriteLine(string.Format(formatProvider, "{0:C}", model.StringAmount));
}
}
So you have a couple of choices:
*
*Convert your data to a numeric type in the template, and then format it.
*Store your data as a numeric type to begin with.
I believe 2 is the better option, because you're wanting to work with numeric data, so storing it as a string only adds complexity when it comes to calculating and formatting (as you can see here), as you're always going to have to perform conversions first. | unknown | |
d9818 | train | From Apple documentation:
// Reference type example
class C { var data: Int = -1 }
var x = C()
var y = x // x is copied to y
x.data = 42 // changes the instance referred to by x (and y)
println("\(x.data), \(y.data)") // prints "42, 42"
Copying a reference implicitly creates a shared instance. After a copy, two variables then refer to a single instance of the data.
A: This is because primitives are value-based types, and classes are reference-based. You can find detailed explanation on Apple's blog.
// Value type example
struct S { var data: Int = -1 }
var a = S()
var b = a // a is copied to b
a.data = 42 // Changes a, not b
println("\(a.data), \(b.data)") // prints "42, -1"
// Reference type example
class C { var data: Int = -1 }
var x = C()
var y = x // x is copied to y
x.data = 42 // changes the instance referred to by x (and y)
println("\(x.data), \(y.data)") // prints "42, 42" | unknown | |

d9821 | train | It seems as if this has a historic background.
What makes using -hd graphics still worthwhile is that loading them doesn't rely on Apple functionality but is rather done in framework code. So -hd can be loaded for iPads in iPhone Simulator mode and make use of the higher resolution pictures in 2x mode.
Other than that I couldn't find any more reasons to not use @2x when I was looking into this a week ago.
In case you want all the details it is probably best to drop riq an email.
A: This seems to be the main reason from this link: http://www.cocos2d-iphone.org/forum/topic/12026
Specifically this post by riq:
I don't know if initWithContentsOfFile was fixed, but in 4.0 it was broken and it wasn't working with @2x, ~iphone extensions.
imageNamed caches all the loaded files so it consumes much more memory than initWithContentsOfFile
Also the @2x extension does something (I don't know exactly what) but it doesn't work OK with cocos2d.
Another good point: Back when the iPhone 4 was just released with the retina display, I am sure some users of Cocos2D were using an older version of it so when the user was using the retina display on a version of Cocos2D that didn't support it, things were twice as large as they should've been. Again this is now fixed to most unless you are using a VERY early version of Cocos2D.
Overview, so it seems that the main issue was with initWithContentsOfFile from iOS 4 but they have fixed this since because I use that exact API with Cocos2D 2.0-rc2 in my app and I do not have any issues whatsoever. I use all Apple specified extensions for images and everything works jolly good! :) | unknown | |
d9822 | train | The validation you are doing is asynchronous. You call the User.find method, and after that the validation method returns. Sequelize has no way of knowing that you are doing something async in your validation, unless you tell it so. Once your find call is done you throw the error, but the validation has completed, so there is no code to catch that error, which means the error is thrown and crashes the app
The way to tell sequelize that you are doing something async is to take a second argument to your function, which is a callback. If you call the callback without any arguments, the validation succeeded, if you give it an argument, the validation failed.
var User = sequelize.define('User', {
username: {
type: DataTypes.STRING,
validate: {
isUnique: function (username, done) {
User.find({ where: { username: username }})
.done(function (err, user) {
if (err) {
done(err);
}
if (user) {
done(new Error('Username already in use'));
}
done();
});
}
}
},
Could you point me to the part of the documentation that mislead you, then we can hopefully correct it :)
A: Sequelize supports Promise style async operations. Specifically the Bluebird.js lib. Just change your function to specifically use the Promise -> next() pattern.
var User = sequelize.define('User', {
username: {
type: DataTypes.STRING,
validate: {
isUnique: function (username) {
User.find({ where: { username: username }})
.then(function (user) {
if (user) {
throw new Error('Username already in use');
}
});
}
}
},
This will also handle any errors on User.find() for you.
See this example in their codebase
Of course the easiest way to handle unique constraints is by setting unique: true on the field definition itself:
var User = sequelize.define('User', {
username: {
type: DataTypes.STRING,
unique: true
},
But this requires that you are either creating the table using Sequelize or already have a table with the unique constraint set.
A: This question got a valid answer which explains how the validation option works. But in this situation you don't have to check if a user exists on your own.
Sequelizejs has a findOrCreate() method, that checks if somethings exists before doing anything.
Very useful method :) | unknown | |

d9827 | train | The problem is that you are always calling the mypass function inside myModule. This happens also when you import it from the main module.
This is why you don't see the password printed to the terminal on the first time when running the main.py file.
You should put the mypass() function call in the myModule inside the
if name == "main" guard.
Change the code inside myModule to the following:
from getpass import getpass
import sys
def mypass():
try:
password = getpass('Password: ')
except Exception as e:
print(e)
sys.exit(1)
while password == '':

d9829 | train | Quoting the manual:
When using ‘fields’ and ‘contain’ options - be careful to include all foreign keys that your query directly or indirectly requires.
A: I think you should remove the 'fields' option and the model name in the fields lists:
$this->Review->Behaviors->attach('Containable');
$latestReviews = $this->Review->find('all', array(
'contain' => array(
'Business' => array(
'fields' => array('name'),
'BusinessType' => array(
'fields' => array('url')
)
)
)));
A: Using the 3.x version :
If you have limited the fields you are loading with select() but also
want to load fields off of contained associations, you can pass the
association object to select():
// Select id & title from articles, but all fields off of Users.
$query = $articles->find()
->select(['id', 'title'])
->select($articles->Users)
->contain(['Users']);
The $articles is the equivalent for $this->Review in the question | unknown | |

d9832 | train | Of course this question will be opinionated because it's fairly broad. Everyone has their own preferred choice. Though if you are a beginner to web programming and you'd like to use python I'd say start with flask. | unknown | |
d9833 | train | Here are some of the possible causes:
*
*The encoding of the file doesn't match the encoding that you are using to read it, and the "pound" character in the file is getting "mangled" into something else.
*The file and your source code are using different pound-like characters. For instance, Unicode has two code points that look like a "pound sign" - the Pound Sterling character (00A3) and the Lira character (2084) ... then there is the Roman semuncia character (10192).
*You are trying to compile a UTF-8 encoded source file without tell the compiler that it is UTF-8 encoded.
Judging from your comments, this is an encoding mismatch problem; i.e. the "default" encoding being used by Java doesn't match the actual encoding of the file. There are two ways to address this:
*
*Change the encoding of the file to match Java's default encoding. You seem to have tried that and failed. (And it wouldn't be the way I'd do this ...)
*Change the program to open the file with a specific (non default) encoding; e.g. change
new FileReader(aFile)
to
new FileReader(aFile, encoding)
where encoding is the name of the file's actual character encoding. The names of the encodings understood by Java are listed here, but my guess is that it is "ISO-8859-1" (aka Latin-1).
A: This is probably a case of encoding mismatch. To check for this,
*
*Print delim.length and make sure it is 1.
*Print inputLine.length and make sure it is the right value (42).
If one of them is not the expected value then you have to make sure you are using UTF-8 everywhere.
You say delim.length is 1, so this is good. On the other hand if inputLine.length is 34, this is very wrong. For "19 x 75 Bullnose Architrave/Skirting £1.02" you should get 42 if all was as expected. If your file was UTF-8 encoded but read as ISO-8859-1 or similar you would have gotten 43.
Now I am a little at a loss. To debug this you could print individually each character of the string and check what is wrong with them.
for (int i = 0; i < inputLine.length; i++)
System.err.println("debug: " + i + ": " + inputLine.charAt(i) + " (" + inputLine.codePointAt(i) + ")");
A: Many thanks for all your replies.
Specifying the encoding within the read & saving the original text file as UTF -8 has worked.
However, the experience has taught me that delimiting text using "£" or indeed other characters that may have multiple representations in different encodings is a poor strategy.
I have decided to take a different approach:
1) Find the last space in the input string & replace it with "xxx" or similar.
2) Split this using the delimiter "xxx." which should split the strings & rip out the "£".
3) Carry on.. | unknown | |

Assuming your rendered html look like this
<div id="repeater_435734957439857435">
<input type="text" class="RepeaterTextbox">Test</input>
<input type="checkbox">
</div>
Your checkbox select event can be something like
$(this).parent().find(".RepeaterTextbox")[0].text();
A: This should work with your markup:
$(document).ready(function () {
$(document).on("click", "input:checkbox[name='chkActive']:checked", function () {
var nexttr = $(this).closest('tr').next('tr');
$(nexttr).find('textarea').each(function () {
alert($(this).val());//Or whatever you want
})

A: Try this, it seems there are multiple textarea you have in nested repeater so the second line in the event handler will loop through each textarea and print value in console.
$("[type=checkbox]").on("change", function () {
var oTexts = $(this).parents("tr").next().find("textarea");
$(oTexts).each(function (ind, val) { console.log($(val).val()); });

d9836 | train | A : in the function signature always means an input argument to the function. The function signature contains the argument label followed by a :. The _ means there's no argument label, in which case you can omit the : as well when supplying that specific input argument to the function call.
This is exactly what you see with the insert(_:at:) function. You supply two input arguments to it, "John" and 3, but it only needs an argument label for the second input argument, hence you only need one :. It's also important to note that at call time, you separate the input arguments using ,, not :.
A: The convention, frequently seen in documentation, is a concise way of referring to a function, using only the function name and argument labels.
So consider this function declaration:
func insert(_ objects: [Any], at indexes: IndexSet)
This is
*
*a method called insert;
*the first parameter name is called objects, this parameter has no argument label (designated with the _) and has a type of [Any]; and
*the second parameter name is indexes, its argument label is at and has a type of IndexSet.
So you call it like so:
insert(someObjects, at: someIndex)
When you call it, you don’t care what the parameter names that are used inside that function, but rather just what the argument labels are. So, the convention when referring to that method in documentation is to omit the parameter names and types and just use the function name and the argument labels, but no comma:
insert(_:at:)
Note, you’d never actually use this syntax in your code. This is just a documentation convention employed to distill long function declarations down to something more manageable and concise:
For more information about argument labels and parameter names, see Function Argument Labels and Parameter Names
A: Swift functions have a unique way of specifying the signature, which is a carry over pattern from Objective C. There are 3 parts to specifying each input argument to the function signature. The signature for the function you mentioned is as follows:
func insert(_ objects: [Any],
at indexes: IndexSet)
Let's look at the second argument first:
*
*at indicates the argument label, which is how the caller specifies the parameter.
*indexes indicates the function's parameter name to the object. This means that in the body of the function, whatever was passed as at: would be referred to as indexes.
*IndexSet is the type of the argument.
Part 1 can be something besides a name, too:
*
*if it is not specified, the argument name and parameter label are the same. For example, if the signature were func insert(objects: [Any], indexes: IndexSet), the function would be called as o.insert(objects: ['a','b'], at: [1,2]).
*If it is an underscore (_), then the argument has no label for the caller. This allows the caller to use the simpler, intuitive call o.insert(['a','b'], at: [1,2]).
A: In a signature, the colon separates the name of a parameter from its value. Functions have this anatomy:
func functionName(label1 parameter1: Type1, label2 paramter2: Type2) -> ReturnType {
...
}
where labels are the names seen when calling the function and parameters are the names of the values as used in the body of the function. A label of _ removes the label from the parameter when calling it.
When calling a function, the colon simply separates parameter labels from the values passed to the function. Commas separate different parameters. A parameter with no label requires no colon. The following function would have no colons at all:
func myFunc(_ par1: Int, _ par2: String) {
print(par1, par2)
}
myFunc(3, "what") // 3 "what" | unknown | |
d9837 | train | You can group the data by ParentCategory and within that group order the grouped data by PackageCost. This should give you the expected output:-
var packageId = objentity.PackageGalleries
.Where(p => p.ParentCategory != "Indian" &&
p.ParentCategory != "International")
.GroupBy(p => p.ParentCategory)
.Select(x => x.OrderBy(p => p.PackageCost).FirstOrDefault())
.ToList();
Update:
For your issue althought I have never experienced such issue but it may be due to deferred execution of LINQ as per this post. You can force execute the query using ToList() as updated. | unknown | |

d9839 | train | Note that in Pandas you can index in ways other than elementwisely with at. In the four-liner below, index is a list which can then be used for indexing with loc.
for parameter in dictionary_of_parameters:
index = df[df[parameter].isin(dictionary_of_parameters[parameter]['target'])].index
df.loc[index,'financialliteracyscore'] += dictionary_of_parameters[parameter]['score']
df['financialliteracyscore'] = df['financialliteracyscore'] /27.0*100

d9840 | train | Difficult to tell from the snippet you provide, but I'd consider having three derived foo classes, FooI1, FooI2 and FooI3, and constructing the appropriate one with a factory based on InputType.
Then all the specializations just get implemented in virtual methods for each of the new classes.
class FooI1: public Foo {
void doSomething() {...};
}
ditto for I2/I3..
Foo * fooFactory(InputType iType)
{
return new FooX - depending on iType
};
Foo *f = fooFactory(i)
f->doSomething();
A: your current code couples Foo and InputType:
1. Foo creates InputType Object
2. InputType calls Foo function
Suggested solution is:
1. Decouple InputType and Foo by using composites mode
Foo could hold a pointer to `InputType*` then call InputType `virtual` function.
2. To make InputType, a factory will simple enough.
Sample code:
class InputType
{
public:
virtual ~InputType();
virtual void DoSomething();
};
InputType* MakeInputObject(const IType& inputType)
{
return new InputTypeX;
}
class Foo
{
public:
Foo(const InputType& input) : input_type_ptr(MakeINputObject(input) {}
void DoSomething() { input_type_ptr->DoSomeThing(); }

d9843 | train | What about this solution:
public class Pages
{
private string _folderName;
public int PageID { get; set; }
public string FolderName
{
get { return _folderName; }
set { _folderName = value?.Trim() ?? string.Empty; }
}
}
A: You need a backing field:
public class Pages
{
public int PageID { get; set; }
private string _folderName;
public string FolderName
{
get { return _folderName; }
set { _folderName = value.Trim(); }
}
}
In the setter method we use the Trim string's method, which
Removes all leading and trailing white-space characters from the current String object.
For further info regarding this method, please have a look here.
A: You may consider writing a custom extension method to call Trim only if the value of your string is not null:
public static class CustomExtensions
{
public static string TrimIfNotNull(this string value)
{
if (value != null)
{
value = value.Trim();
}
return value;
}
}
And then in your Pages class, something like
private string _folderName;
public string FolderName
{
get { return _folderName.TrimIfNotNull(); }
set { _folderName = value.TrimIfNotNull(); }
}
If you're using C#6, as mentioned by Jacob Krall, you can use the null conditional operator directly and not worry about the extension method:
public string FolderName
{
get { return _folderName; }
set { _folderName = value?.Trim(); }
}
A: The shorthand syntax for properties is only for when you want to provide a thin layer of abstraction on top of a field. If you want to manipulate the field within the getter or setter, you need to specify the backing field on your own.
namespace sample.Models
{
public class Pages
{
public int PageID { get; set; }
private string folderName;
public string FolderName
{
get { return folderName; }
set { folderName = value.Trim(); }
}
}
}
A: public class Pages
{
public int PageId { get; set; }
// you need a backing field then you can customize the set and get code
private string folderName;
public string FolderName
{
get { return this.folderName; }
// if the fileName can be set to null you'll want to use ?. or you'll get
// a null reference exception
set { this.folderName = value?.Trim(); }
}
}
A: See the code below.
//You can filter the entry before saving it into the database.
//About the null issue. You can use this.
if(String.IsNullOrEmpty(txtusername.Text))
{
throw new Exception("Cannot be blank!");
}
//You can filter the entry before saving it into the database
txtpageid.Text = book.PageID.Trim();
txtfoldername.Text = book.FolderName.Trim(); | unknown | |

d9845 | train | Just use something like df[df != 0] to get at the nonzero parts of your dataframe:
import pandas as pd
import numpy as np
np.random.seed(123)
df = pd.DataFrame(np.random.randint(0, 10, (5, 5)), columns=list('abcde'))
df
Out[11]:
a b c d e
0 2 2 6 1 3
1 9 6 1 0 1
2 9 0 0 9 3
3 4 0 0 4 1
4 7 3 2 4 7
df[df != 0] = 1
df
Out[13]:
a b c d e
0 1 1 1 1 1
1 1 1 1 0 1
2 1 0 0 1 1
3 1 0 0 1 1
4 1 1 1 1 1
A: As an unorthodox alternative, consider
%timeit (df/df == 1).astype(int)
1000 loops, best of 3: 449 µs per loop
%timeit df[df != 0] = 1
1000 loops, best of 3: 801 µs per loop
As a hint what's happening here: df/df gives you 1 for any value not 0, those will be Inf. Checking ==1 gives you the correct matrix, but in binary form - hence the transformation at the end.
However, as dataframe size increases, the advantage of not having to select but simply operate on all elements becomes irrelevant - eventually you it becomes less efficient.
A: Thanks Marius. Also works on just one column when you want to replace all values except 1. Just be careful, this does it inplace

d9855 | train | Machine Independence
Machine independence refers to the idea of software that can be executed irrespective of the machine on which it executes. A piece of Machine dependent software might be something written to use, say assembly instructions that are specific to a certain architecture. For example, if you write a C++ application with inline assembly that relies on special processor instructions such as for example, SIMD instructions, then that peice of software is machine dependent because it has specific machine requirements - it can only work on a machine that supports that specific required SIMD instruction set.
In contrast, C# and Java compile to bytecode that is executed by a virtual machine which takes that bytecode and executes it as native code directly on the processor. In this case the virtual machine is machine dependent because it will execute against the specific hardware it is written for - for example, only a 32 bit Intel processor, or an ARM Smartphone. The Java and C# applications that run on the virtual machine however are machine independent because they care not what the underlying platform is, as long as there is a virtual machine to translate to the underlying paltform for them. That abstraction layer, the virtual machine, helps separate the application from the underlying hardware and that is the reason why those applications can be machine independent.
Portability
Portability is a separate but related concept, it is a broad term that covers a number of possibilities. A piece of software is portable simply if it can be built and executed or simply executed on more than one platform. This means that machine independent software is inherently portable as it has to be by nature.
There are broadly two facets to portability - hardware portability, and software portability. Ignoring for the moment .NET implementations such as Mono and focussing purely on Microsoft's .NET implementation it is fair to say that .NET is hardware portable because it can be executed on any hardware that supports the .NET runtime, however because Microsoft's implementation is only available on Windows and Windows descended operating systems it is fair to say that it is not particularly software portable - without Mono it cannot be executed on Mac OS X or Linux. In contrast, Java could be said to be both hardware portable and software portable because it can run on multiple operating systems like Windows, OS X, Linux hence it is software portable, and hardware portable because it can run on different hardware architectures such as ARM, x86 and x64.
Finally, there is also the question of language portability. Many would argue that although a C++ application compiled for Windows will not natively execute on Linux, it is possible to write C++ code in such a way that the same set of source code can be compiled on both Linux and Windows with no changes - this means that you can port the same application to different operating systems simply by just compiling it as is. In this respect we can say that whilst a compiled C++ application is not portable, the source code for a C++ application can be portable. This applies to a number of other languages including C.
Disclaimer
This is a somewhat simplified explanation and there are many edge cases that break these rules which make it such a complex and subjective subject - for example it is possible to write a Java application that is machine dependent if for example you use the Java native interfaces.
A: Portable means that you can run this programm without any installation.
Machine independent means that the same code can be executed on different OS.
This question could be helpfull, too.
A: From Wikipedia:
Software is portable when the cost of porting it to a new platform is
less than the cost of writing it from scratch. The lower the cost of
porting software, relative to its implementation cost, the more
portable it is said to be.
Machine-independent software, on the other hand, does not need any work to be ran on another machine (ex. from Windows to Mac OS). It is by this definition also highly portable.
A:
What is difference between PORTABLE and Machine Independent?
There is no real answer to this. It depends on whose definitions of "portable" and "machine independent" you chose to accept. (I could pick a pair of definitions that I agree with and compare those. But I don't think that's objective.)
What is Java, c#.net : portable or machine independent?
You could argue that Java and C# are neither portable or machine independent.
*
*A Java or C# program only runs on a platform with a JVM or CLR implementation, and a "compliant" implementation of the respective standard libraries. Ergo, the languages are not machine independent (in the literal sense).
*There are many examples of Java (and I'm sure C#) programs that behave differently on different implementations of Java / C#. Sometimes it is due to differences in runtime libraries and/or the host operating system. Sometimes it is due to invalid assumptions on the part of the programmer. But the point is that Java / C# software often requires porting work. Ergo, they are not portable (in the literal sense.) | unknown | |

As per Reference Manual, page 948, the max baud rate for UART of STM32F334 is 9Mbit/s.
If we want to send memory at the specific address, it will be 32 bits. 1 bit takes 1/9Mbps or 1.111*10^(-7)s, multiply that by 32 bits, that makes it 3.555 microseconds. Obviously, as I said, it's purely napkin math. There are start and stop bits involved. But we have a lot of wiggle room. You can easily fit 64 bits into transmission too.
Now, I've checked with the internet, it seems the ST-Link based on STM32F103 can have max baud rate of 4.5Mbps. A bummer, but we simply need to double our timings. 3.55*2 = 7.1us for 32-bit and 14.2us for 64-bit transmission. Even given there is some start and stop bit overhead, we still seem to fit into our 25us time budget.
So the suggestion is the following:
You have a timer set to 25us period that fires an interrupt, that activates DMA UART transmission. That way your MCU actually has very little overhead since DMA will autonomously handle the transmission, while your MCU can do whatever it wants in the meantime. Entering and exiting the timer ISR will be in fact the greatest part of the overhead caused by this, since in the ISR you will literally flip a pair of bits to tell DMA to send stuff over UART @ 4.5Mbps. | unknown | |
d9866 | train | I did not look through all your code. I will answer only your question. You have to pass pRoot to TTree_Insert by reference. Otherwise you pass its copy to the function and any changes of the copy within the function do not influence the original value.
For example
void TTree_Insert ( TNo **pRoot, char word[80] ){
char* c = malloc(sizeof(char)*strlen(word) + 1 ); // <==
strcpy( c, word ); // <==
TNo* pAux;
pAux = *pRoot;
//...
And in main you have to call the function like
TTree_Insert( &pRoot, aux );
Take into account that you have to adjust all other code of the function. For example
void TTree_Insert( TNo **pRoot, const char word[80] )
{
char* c = malloc( sizeof( char ) * strlen( word ) + 1 );
strcpy( c, word );
TNo **pAux = pRoot;
while ( *pAux != NULL )
{
printf("TESTE");
if ( strcmp(c, ( *pAux )->item.key ) < 0 )
{
pAux = &pAux->pLeft;
}
else if ( strcmp(c, ( *pAux )->item.key ) > 0 )
{
pAux = &pAux->pRight;
}
else
{
( *pAux )->item.no++;
break;
}
}
if ( *pAux == NULL ) *pAux = TNo_Create(c);
return;
}
I hope it will work.:)
A: pRoot is initially NULL, and you never change it later.
so it seems the pAux is always NULL for some reason

(Yes, I know that requires VS (and AFAIK VS10 has this OOTB))
A: On my linux box with a local other than C (tested fr_FR, fr_FR.UTF-8, en_US, en_GB), the sort command sorts as you expect. You could very well pipe to the sort command :
:1,4!sort
If you are on windows, I suppose you can install unix tools (like SFU) that could do the job since vim's sort command doesn't seem to handle locale. | unknown | |

d9871 | train | The problem described in the question can be resolved by changing the application.css.scss manifest to use import instead of require:
@import "bootstrap_local";
It is also necessary to remove any require_tree . from the manifest because it would otherwise require the same bootstrap_local file because it lies in its path.
On reflection, not having require tree . in the manifest is probably wise because it prevents unwanted files from being included. I only had it there because it's there by default in a new Rails project (the same goes for require_self; it's cleaner not to put that in the manifest).
In reference to the suggestion about prefixing the file with an underscore, this is a good thing to do when the you don't need file, like bootstrap-social in the question, to be a compiled into a separate CSS file. So, I did end up renaming it to _bootstrap-social.scss. | unknown | |
d9872 | train | Found it!
The variable hash is not in hexadecimal format - well, it actually is, but not in the way the system wants it. I don't understand why, but the fact is that you have to do a hash.toHex() in order to get the right value. So, the solution is something like this:
const hash = await api.tx.balances
.transfer(to, amount)
.signAndSend(from, { tip, nonce: -1 })
.catch(e => {
throw e;
});
return hash.toHex();

d9877 | train | A submodule can work, but if you try to clone something that contains submodules for which one of the remotes is unavailable, you'll have aggravating errors.
My alternative would be to use the 'filter-branch' command to maintain a public branch that would omit the copyrighted files for public consumption on GitHub.
A: You could use the git submodule support to hold the "copyrighted" directory in a separate Git repository. Keep this separate repository somewhere accessible to people who should be able to see it, and don't push it to github. For people accessing the public repository, they would see a reference to a "copyrighted" repository but would be unable to populate it.
A: I think it is not possible.
What you can try is to put "copyrighted" directory in a separate branch which is not mirrored, but it will just make more hassle. | unknown | |
d9878 | train | Use the struct module (documentation), specifying the data as a float. | unknown | |
d9879 | train | You need to use extern "C" to prevent name mangling and ensure the function is exported:
extern "C" __declspec(dllexport) void Myfunction(BOOL);
To view the exports from your DLL you can use dumpbin.exe utility that is shipped with Visual Studio:
dumpbin.exe /EXPORTS MyDll.dll
This will list the names of all exported symbols.
In addition to this do not have either of the following compiler switches specified:
Gz __stdcall calling convention: "Myfunction" would be exported as Myfunction@4
Gr __fastcall caling convention: "Myfunction" would be exported as @Myfunction@4
Note: I think last symbol is dependent on compiler version but is still not just "Myfunction".
A: The DLL export process is subject to name mangling and decoration. The long obsolete 16 bit pascal calling convention is equivalent to stdcall on 32 bit platforms.
First of all you should use extern "C" to specify C linkage and disable name mangling.
However, your function will still be subject to name decoration. If you export it with __declspec(dllexport) then it will in fact be exported with the name _Myfunction@4. If you wish to export it by its true name then you need to use a .def file.
However, the possibility still remains that you did not export the function from the DLL at all. Use Dependency Walker to check whether it was exported, and if so by what name.
A: Why are you using the pascal calling-convention? Perhaps that alters the names of symbols, and if so you might need to take that into account.
A: The symbol is going to be decorated, so it will never be called MyFunction, its more likely _MyFunction@4. you can quickly check this using something like dumpbin.
You can read up more on mangling here, if you want to avoid mangling, you need to use a def file to specify symbol names (or ordinals). | unknown | |

d9886 | train | Singleton pattern is a common approach if you only want one instance of the object. A lot of people regard it as an anti-pattern, yet it is still very popular. Spring beans are singletons, and redux store is a singleton!
If you are only using it in one method, you might as well free up the heap and store it locally in the method, as described here. Freeing up the heap will technically give better performance, but Java is not exactly a super-efficient language anyway, and it also manages the memory for you. Memory generally isn't a problem though, because it's quite cheap and we have lots of it (maybe I should be more careful about my memory management!) | unknown | |

d9890 | train | Three issues appear to need attention.
*
*"time to go" needs to be stored outside the screen update function and decremented or calculated each time the screen is updated.
*using parseInt to convert numbers to integer numbers is regarded as a hack by some. Math.floor() or integer calculation can be alternatives.
*Timer call backs are not guaranteed to made exactly on time: counting the number of call backs for a 10msec time does not give the number of 1/100ths of elapsed time.
The following code is an example of how it could work, minus any pause button action.
var countdownTimer;
var endTime;
var counter = 0; // ** see reply item 3. **
function startCountDown( csecs) // hundredths of a second
{ endTime = Date.now() + 10*csecs; // endTime in millisecs
decrement();
countdownTimer = setInterval(decrement, 10);
counter = 0; // testing
}
function decrement()
{ var now, time, mins, secs, csecs, timeStr;
++ counter; // testing
now = Date.now();
if( now >= endTime)
{ time = 0;
timeStr = "Times up! counter = " + counter;
clearInterval( countdownTimer);
}
else
{ time = Math.floor( (endTime - now)/10); // unit = 1/100 sec
csecs = time%100;
time = (time-csecs)/100; // unit = 1 sec
secs = time % 60;
mins = (time-secs)/60; // unit = 60 secs
timeStr =
( (mins < 10) ? "0" + mins : mins) + ":" +
( (secs < 10) ? "0" + secs : secs) + ":" +
( (csecs < 10) ? "0" + csecs : csecs);
}
document.getElementById("output").innerHTML=timeStr;
}
The argument to startCountDown gives the number of 1/100ths of second for the count down. If the counter result is the same as the argument,try swapping browser tabs and back again during the countdown.
HTML to test:
<button type="button" onclick="startCountDown(600)">start</button>

I get no offload to the GPU. If you can't reproduce this, then the problem is either with your compiler version (you haven't said which one you are using), if you can, then perhaps the somewhat fancier build options you are using are interacting with NVBLAS in an unexpected way | unknown | |
d9892 | train | You ever heard of SQL Server? Like SQL Server EMBEDDED? No install ;)
A: You have contradictory requirements.
Small and embedded (no server) usually means SQL Server compact or SQLLite. But these are neither multi-user not network aware in practice. Especially whan you say "hundreds of multiple users"
So you have to decide what you want to do. A proper, scalable, web based app with correct architecture? Or a a cheap kludgely unworkable unmaintainable mess?
SQL Server Compact will scale up of course in future to normal SQL Server with minimum fuss. But I'd start with SQL Server properly now
A: You can use FireBird, it can be embedded and scales well and deployment is really easy - an ADO.NET provider is available... see for more information http://www.firebirdsql.org/en/net-provider/ | unknown | |
d9893 | train | public List<string> FirstNames
{
get
{
return _contactList.Select(C => C.FirstName).ToList();
}
}
A: You want to use the Select method, not Where here:
_contactList.Select(C => C.FirstName).ToList();
Further, the need for the ToList() only exists because the property demands it. You could return an IEnumerable<string> instead if you wanted to get rid of that. | unknown | |
d9894 | train | I can't reproduce the problem.
If I run this snippet of code:
myRef.orderByKey().addValueEventListener(new ValueEventListener() {
public ArrayList<Long> mDataArrayList;
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
if (mDataArrayList == null) {
mDataArrayList = new ArrayList<>();
} else {
mDataArrayList.clear();
}
getDataChange(dataSnapshot);
System.out.println(mDataArrayList);
}
private void getDataChange(DataSnapshot dataSnapshot){
try {
for (DataSnapshot data : dataSnapshot.getChildren()){
long timestamp = Long.parseLong(data.getKey());
mDataArrayList.add(timestamp);
}
}
catch (Exception e){
System.err.println("onDataChange Exception: " + e.toString());
}
}
@Override
public void onCancelled(DatabaseError databaseError) {
throw databaseError.toException();
}
});
With this JSON:
{ "1476986154" : true, "1477280739" : true }
It prints:
[1476986154, 1477280739]
Which seems the correct order to me since 1476986154 < 1477280739. | unknown | |
d9895 | train | Seems I had automatic backup turned on but the config file was missing. So, the server looked like it started up but actually didn't.
I created the config file and set enabled to false. Still didn't start up because it sees the false and stops the configuration and throws an exception because the 'delay' parameter isn't set.
I think orientdb should start up without backups enabled if the config file is missing or the enabled parameter is set to false.
At least the console is working now. | unknown | |
d9896 | train | An overload of CreateFullTextQuery exists that allows you to specify the types to search:
fullTextSession.CreateFullTextQuery(query, typeof(EntityA), typeof(EntityB)).List<ISearchable>();
It's a little clunky having to specify all the types, but they load fine. The only remaining problem I have is that my assumption that you could just do an all fields search by default was incorrect, so it requires building a MultiFieldQueryParser over all properties of all searchable entities:
private static Query ParseQuery(string query, IFullTextSession searchSession)
{
var parser = new MultiFieldQueryParser(GetAllFieldNames(searchSession), new StandardAnalyzer());
return parser.Parse(query);
}
private static string[] GetAllFieldNames(IFullTextSession searchSession)
{
var reader =
searchSession.SearchFactory.ReaderProvider.OpenReader(
searchSession.SearchFactory.GetDirectoryProviders(typeof (Company)));
var fieldNames = reader.GetFieldNames(IndexReader.FieldOption.ALL);
return fieldNames.Cast<string>().ToArray();
} | unknown | |
d9897 | train | I originally wrote a for loop that was straightforward but I incurred in the problem to delete item(i) recursively. The next item previously accessed as item(i+1) will decrease by 1, creating a strange effect of erasing several rows unexpectedly.
As proposed by @absolute.madeness, below the solution that avoids that. I hope other will benefit from this solution and don't get stuck wondering why a simple loop can create such unexpected issues:
MainWindow::MainWindow(QWidget *parent)
: QMainWindow(parent)
, ui(new Ui::MainWindow)
{
ui->setupUi(this);
remove = new QAction(QIcon(":/icons/remove_item.png"), "Remove", this);
QObject::connect(remove, SIGNAL(triggered()), this, SLOT(on_eraseBtn_clicked()));
// other operations in the constructor....
}
void MainWindow::on_eraseBtn_clicked()
{
for(auto item: ui->listWidget->selectedItems())
if(item->text() != "Add New") delete item;
}
This way the user selectively erase single rows in the QListWidget leaving only a specific row. | unknown | |
d9898 | train | Jobs are asynchronous. Your code is not.
Ignoring for the moment the fact that if you're dynamically granting privileges that something in the world is creating new tables live in production without going through a change control process (at which point a human reviewer would ensure that appropriate grants were included) which implies that you have a much bigger problem...
When you run the CREATE TABLE statement, the trigger fires and a job is scheduled to run. That job runs in a separate session and can't start until your CREATE TABLE statement issues its final implicit commit and returns control to the first session. Best case, that job runs a second or two after the CREATE TABLE statement completes. But it could be longer depending on how many background jobs are allowed to run simultaneously, what other jobs are running, how busy Oracle is, etc.
The simplest approach would be to add a dbms_lock.sleep call between the CREATE TABLE and the SELECT that waits a reasonable amount of time to give the background job time to run. That's trivial to code (and useful to validate that this is, in fact, the only problem you have) but it's not foolproof. Even if you put in a delay that's "long enough" for testing, you might encounter a longer delay in the future. The more complicated approach would be to query dba_jobs, look to see if there is a job there related to the table you just created, and sleep if there is in a loop. | unknown | |
d9899 | train | use the split function:
string[] paths = txtattach.Text.Split(',');
A: One way to do this is using the Split method so you easily can iterate over the items in a loop:
foreach(var filename in txtAttach.Text.Split(','))
{
// Do something with filename
} | unknown | |
d9900 | train | A different approach:
final = []
for i in range(10):
temp = ["." for j in range(10)]
temp[int(i / 2)] = "#"
temp[int(i / 2) + 1] = "#"
temp[-int(i / 2) - 1] = "#"
temp[-int(i / 2) -2] = "#"
final.append(temp)
for a in final:
print("".join(a))
Will print:
##......##
##......##
.##....##.
.##....##.
..##..##..
..##..##..
...####...
...####...
....##....
....##....
This can be made even cleaner, but here you can see all the different steps, so I hope it helps
A: # 10x10
# first # start position second # start position from last
# LN 0 1: 0 -1
# LN 2 3: 1 -2
# LN 2k 2k+1: k -k-1
# LN 8 9: 4 -5
# dw: dot '.' width
# sw: sharp '#' width
# if k == 0 part is ugly, for list slicing
def draw(dw, sw):
for k in range(dw//2):
row = [ '.' for _ in range(dw) ]
row[k:k+sw] = '#' * sw
if k == 0:
row[-sw:] = '#' * sw
else:
row[-k-sw:-k] = '#' * sw
print("".join(row))
print("".join(row))
draw(10, 2)

A: I would use itertools' product, and filter the indices that aren't relevant
def v(row):
return set([int(row/4), row-int(row/4), int(row/4)+1, row-int(row/4)-1])
from itertools import product
indices = product(range(len(array)),range(len(array[0])))
indices = filter(lambda i: i[1] in v(i[0]), indicies)
for r,c in indices:
array[r][c] = "#"
A: Don't know what you're trying to accomplish here, but I can do it, too:
a = "##..."
for i in range(10):
b = ("."*int(i/2) + a)[:5]
print(b + b[::-1])
A: Slightly more concise:
width = 10
for i in range(width):
line = ['.'] * width
m = i//2
line[m] = line[m+1] = line[-m-1] = line[-m-2] = "#"
print(''.join(line)) | unknown |
