d12601 | train | Try this:
<script>
if (parseInt$('.ezfc-price-value').text()) > 24){
$('.ly-radio-livraison').prop("disabled", false);

You need to compare the text inside that element, not the element itself.
Hope this helps.

d12602 | train | Since you have only one Canvas and each Visual can have only one parent in visual tree therefore each time you place your resource it's put in that place of visual tree and removed from the previous place. You can either put Canvas directly into ViewBox in UserControl and make Path a resource or you can try setting x:Shared attribute to false on your Canvas which should result in new instance of resource being created each time you refer to it:
<Application.Resources>
<Canvas x:Key="appbar_close" x:Shared="False" ...>
<!-- -->
</Canvas>
</Application.Resources>
A: Set x:Shared=false on resource. It will work.
<Canvas x:Key="appbar_close" x:Name="appbar_close" x:Shared="false" Width="76" Height="76" Clip="F1 M 0,0L 76,0L 76,76L 0,76L 0,0" > | unknown | |
d12603 | train | The best practice is to use a normalized database schema. Then the DBMS keeps it up to date, so you don't have to.
But I understand the tradeoff that makes a denormalized design attractive. In that case, the best practice is to update the total on every change. Investigate triggers. The advantage of this practice is that you can make the total keep in sync with the changes so you never have to think about whether it's out of date or not. If one change is committed, then the updated total is committed too.
However, this has some weaknesses with respect to concurrent changes. If you need to accommodate concurrent changes to the same totals, and you can tolerate the totals being "eventually consistent," then use periodic recalculation of the total, so you can be sure only one process at a time is changing the total.
Another good practice is to cache aggregate totals outside the database, e.g. memcached or in application variables, so you don't have to hit the database every time you need to display the value.
The query "select sum(points) as total from points where id = ?" should not take 2 seconds, even if you have a huge number of rows and a lot of requests.
If you have a covering index defined over (id, points) then the query can produce the result without reading data from the table at all; it can calculate the total by reading values from the index itself. Use EXPLAIN to analyze your query and look for the "Using index" note in the Extra column.
CREATE TABLE Points (
id INT,
points INT,
reason VARCHAR(10),
KEY id (id,points)
);
EXPLAIN SELECT SUM(points) AS total FROM Points WHERE id = 1;
+----+-------------+--------+------+---------------+------+---------+-------+------+--------------------------+
| id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra |
+----+-------------+--------+------+---------------+------+---------+-------+------+--------------------------+
| 1 | SIMPLE | points | ref | id | id | 5 | const | 9 | Using where; Using index |
+----+-------------+--------+------+---------------+------+---------+-------+------+--------------------------+
A: By all means keep the underlying table normalized. If you can deal with data potentially being one day old, run a script each nigh (you can schedule it), to do the roll up and populate the new table. Best to just re-create the thing each night from the source table to prevent any inconsistencies between the two.
That said, with the size of your record, you must either have very slow server, or very large # of records, because a record that small, with an indexed field on id should sum very quickly for you - however, I am of the mindset that if you can improve user response time by even a few seconds, there is no reason not to use rollup tables - even if DB purists object.
A: Have the extra totalpoints column on the same table, and create/update the value of totalpoints for every row creation/update.
If you need totalpoints for a certain record, you can lookup the value without computing totalpoints. For example if you need the last value of totalpoint, you can get it like this:
SELECT totalpoint FROM point ORDER BY id DESC LIMIT 1;
A: There is another approach: caching. Even if it's cached for only a few seconds or minutes, that is a win on a frequently accessed value. And it's possible to dissociate the cache-fetch with the cache-update. That way, a reasonably current value is always returned in constant time. The tricky bit is having the fetch spawning a new process to do the update.
A: I'd suggest to create a layer that you use to access and modify the data. You can use these DB access functions to encapsulate the data maintenance in all tables to keep the redundant data in sync.
A: You could go either way in this case, because it's not very complicated.
I prefer, as a general rule, to allow the data to be temporarily inconsistent, by having just enough redundancy, and have a periodic process resolve the inconsistencies. However, there is no harm in having a trigger mechanism to encourage early execution of the periodic process.
I feel this way because relying on event-based notification-style code to keep things consistent can, in more complex cases, greatly complicate the code and make verification difficult.
A: You could also create another reporting schema and have it reload at fixed intervals via some process that does the calculations. This is not applicable to realtime information - but is very standard way of doing things.

d12607 | train | System.out.println(((JButton) e.getSource()).getName() + " Click");
A: You can cast to a JComponent if you know that only JComponents will be the return value of e.getSource() I'm using JComponent as the cast since it gives more flexibility. If you're only using JButtons, you can safely cast to a JButton instead.
@Override
public void actionPerformed(ActionEvent e) {
if (e.getSource() == thirdBtn) {
//System.out.println("Third Button Click");
System.out.println(((JComponent) e.getSource()).getName()+" Click");
}
}
Feel free to replace getName() with getText(), depending on what exactly you need.
Also, the == operator should only be used to compare Object references, so consider casting to a JComponent from the beginning and using .equals() on the names or text.
Edit
You can't output the name of the variable, but you can set the name/text of the JComponent.
Eg
JButton btnExample = new JButton();
btnExample.setName("btnExample");
Or if you want "btnExample" to actually be displayed on the button:
JButton btnExample = new JButton();
btnExample.setText("btnExample"); | unknown | |
d12608 | train | While I doubt the original poster is still around, the answer may be interesting to others encountering the same situation.
The problem OP encounters here is that he does not have the correct rights to modify/delete the next.trk file in the default ado folder. Usually this happens when you do not have admin rights on a (heavily) locked-down server.
One solution is to copy the files directly: however, this can be rather tricky if the server is really locked down, or you have programs with unspecified dependencies.
The alternative is to change your ado folder. OP took the correct first step by altering the location of net install through net set ado "somefoldername". However, they missed the second step, which tells Stata "somefoldername" is part of the adopath.
This is done through adopath ++ "somefoldername". If I'm not mistaken, this only stays active as long as Stata is open. To make this "permanent", that line of code should be added to the profile.do dofile, which runs automatically at Stata startup. See the Stata FAQ for more information on the profile.do file. | unknown | |
d12609 | train | You will need to pass the length as an additional parameter. Using an assumed-shape array will not work, here's why:
In the ABI employed by most Fortran compilers, arrays as parameters ("dummy arguments") can take one of two representations, depending on the interface used in the subroutine/function:
*
*Those passed with known sizes or assumed sizes, like arr(n) or arr(*), usually receive just a pointer to the first element, with elements assumed to be contiguous.
*Those passed with assumed shapes, like arr(:) receive an array descriptor structure. This is completely implementation dependent, but usually such a structure contains the pointer to the first element of the data plus information on the bounds of each dimension, the stride, etc.
That is the reason why you can directly pass a single row, or only the elements in even indices, of an array if the function receives it as an assumed shape array: the descriptor structure encodes the information that the data is not necessarily contiguous and so the Fortran compiler does not need to copy arr(5:2:) to a temporary location in memory.
The reason why you cannot use such facilities to communicate with Java is that the descriptor structure is completely non-standard, a part of the particular ABI of each compiler. Thus, even if you somehow managed to understand how to build it (and it would be non trivial) the next version of your compiler could bring a total change. | unknown | |
d12610 | train | I could integrate Onesignal in my ios app.
The issue was in config.xml
I commented the push related tags in config.xml. | unknown | |
d12611 | train | I would try the following approach using the following CSS:
#navbar > ul > li
{
float: left;
margin-left: 21px;
font-family: 'Open Sans', sans-serif;
font-size: 14px;
text-transform: uppercase;
color: #fff;
border-top: 2px solid transparent;
padding-top: 8px;
position: relative;
line-height: 1.5;
height: 24px;
}
#navbar > ul > li > ul {
list-style: none;
position: absolute; /* change this */
margin-left: 0px;
padding-left: 0px;
margin-top: -5px; /* this can control the whitespace... */
}
Add position: relative to the li elements in your primary navigation, and add some line height and height values as needed.
For the secondary navigation, change position to absolute on the ul and tweak
the top margin to close any whitespace.
See demo at: http://jsfiddle.net/audetwebdesign/adw5hp84/
By using absolute positioning of the secondary menus, you take them out of the flow of the main menu bar and you don't have to worry that the length of the labels will affect the primary navigation layout.
Note that there is probably more detailed work to be done on styling the spacing between links and so on.
A: Get rid of the width in #navbar > ul > li.navbar_multiple:hover > ul > li:
#navbar > ul > li.navbar_multiple:hover > ul > li {
display:block;
height:20px;
padding-left: 10px;
margin-left: 0px;
}
Updated your fiddle: http://jsfiddle.net/ktvde9qo/11/
EDIT: To make all submenu items have the same width, simply remove (or comment out) the following lines, alternatively modify them for your needs:
#navbar > ul > li > ul > li:first-child {
margin-top: 8px;
padding-top: 9px;
width: 100%;
}
Fiddle updated: http://jsfiddle.net/ktvde9qo/13/
EDIT 2: To make the submenu items longer than the main menu item, just add a longer width to the submenu item and a shorter one to the main:
The submenu item:
#navbar > ul > li > ul > li {
padding-left: 0px;
display: none;
text-transform: none;
font-size: 12px;
padding: 4px 4px 8px 6px;
padding-top: 10px;
border-top: 1px solid #39718e;
background-color: #316885;
width:200px; /* changed this */
}
The main menu item:

d12612 | train | Mapserver is very easy to setup and learn. Implementing any kind of rendering by yourself is going to require much more effort, and you will probably find a lots of unexpected traps.
mapserver cgi should be enough for your needs. If you require some very specific tweak, then mapscript can be useful.
I think it could be interesting if you could make a pure JavaScript application, and save yourself from installing a web server (and a map server). If you just needed browsing a tile mosaic, may be you could do it just with JavaScript (generate an html table with a cell for each tile). You can render points or polygons, with JavaScript, using a canvas and doing some basic coordinate conversion to translate geographic points to pixels. Openlayers have this functionality, I think.
EDIT: I just checked and with Openlayers you can browse local tiles, and you can render kml and some other vect data. So, I think you should give Openlayers a try.
A: No need to have a wms/wfs. What you need is a tile implementation. Basically you should have some sort of central service, or desktop service that generates the tiles. Once these tiles are generated, you can simply transform them to your "no-real-webserver-architecture" filesystem. You can create a directory structure that conforms to /{x}/{y}/{z}.png and call it from javascript.
An example of how openstreetmap does this can be found here: http://wiki.openstreetmap.org/wiki/OpenLayers_Simple_Example
A: You may like featureserver: http://featureserver.org/.

d12616 | train | A http request only gets a single http response. Using http, you only get one response. Some options for you:
1) Wait for everything to finish before replying. Make sure each part creates a result, success or failure, and send the multiple responses at once. You would need some control flow library such as async or Promises to make sure everything responded at the same time. A good choice if all parts will happen "quickly", not good if your user is waiting "too long" for a response. (Those terms were in quotes, because they are application dependent).
2) Create some scheme where the first response tells how many other responses to wait for. Then you'd have a different HTTP request asking for the first additional message, and when that returns to your client, ask for the second additional message, and so on. This is a lot of coordination though, as you'd have to cache responses, or even try again if they were not done yet. Using a memory cache like redis (or similar) could fulfill the need to holding responses until ready, with a non-existent meaning 'not ready'
3) Use an eventing protocol, such as WebSockets, that can push messages from the server. This is a good choice, especially if you don't know how long some events would occur after the trigger. (You would not want to stall a HTTP request for tens of seconds waiting for 3 parts to complete - user will get bored, or quit, or re-submit.). Definitely check out the Primus library for this option. It can even serve the client-side script, which makes integration quick and easy. | unknown | |

d12618 | train | You aren't giving the consumer application any time to actually receive a message, you create it, then you close it. You either need to use a timed receive call to do an sync receive of the message from the Queue or you need to add some sort of wait in the main method such as a CountDownLatch etc to allow the async onMessage call to trigger shutdown once processing of the message is complete.
A: What @Tim Bish said is correct. You either need to have a timer say for example receiver should listen for 1 hour- or make it available until program terminate. Either case you need to start your consumer program once:
Change your receiveJMS method as follows:
public void receiveJMS() throws NamingException, JMSException {
try{
ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(ActiveMQConnection.DEFAULT_BROKER_URL);
Connection connection = connectionFactory.createConnection();
connection.start(); // it's the start point
Session session = connection.createSession(false,Session.AUTO_ACKNOWLEDGE);
// Getting the queue 'testQueue'
Destination destination = session.createQueue("testQueue");
MessageConsumer consumer = session.createConsumer(destination);
// set an asynchronous message listener
// JMSReceiver asyncReceiver = new JMSReceiver();
//no need to create another object
consumer.setMessageListener(this);
connection.setExceptionListener(this);
// connection.close(); once this is closed consumer no longer active
Thread.sleep(60 *60 * 1000); // receive messages for 1 hour
}finally{
connection.close();// after 1 hour close it
}
}
The above program will listen upto 1 hour. If you want it as long as the program run, remove the finally block. But the recommended way is to close it somehow. since your application seems to be standalone ,you can check the java runtime shutdown hook, where you can specify how to release such resources while program terminates.
If your consumer is a web application you can close it in a ServletContextlistner. | unknown | |

File.AppendAllText(outputPath, data);
A: string path=@"E:\AppServ\Example.txt";
if(!File.Exists(path))
{
File.Create(path).Dispose();
using( TextWriter tw = new StreamWriter(path))
{
tw.WriteLine("The very first line!");
}
}
else if (File.Exists(path))
{
using(TextWriter tw = new StreamWriter(path))
{
tw.WriteLine("The next line!");
}
}
A: When you start StreamWriter it's override the text was there before. You can use append property like so:
TextWriter t = new StreamWriter(path, true);
A: else if (File.Exists(path))
{
using (StreamWriter w = File.AppendText(path))
{
w.WriteLine("The next line!");
w.Close();
}
}
A: Try this.
string path = @"E:\AppServ\Example.txt";
if (!File.Exists(path))
{
using (var txtFile = File.AppendText(path))
{
txtFile.WriteLine("The very first line!");
}
}
else if (File.Exists(path))
{
using (var txtFile = File.AppendText(path))
{
txtFile.WriteLine("The next line!");
}
}
A: You don't actually have to check if the file exists, as StreamWriter will do that for you. If you open it in append-mode, the file will be created if it does not exists, then you will always append and never over write. So your initial check is redundant.
TextWriter tw = new StreamWriter(path, true);
tw.WriteLine("The next line!");
tw.Close();
A: You could use a FileStream. This does all the work for you.
http://www.csharp-examples.net/filestream-open-file/
A: Use the correct constructor:
else if (File.Exists(path))
{
using(var sw = new StreamWriter(path, true))
{
sw.WriteLine("The next line!");
}
}
A: File.AppendAllText adds a string to a file. It also creates a text file if the file does not exist. If you don't need to read content, it's very efficient. The use case is logging.
File.AppendAllText("C:\\log.txt", "hello world\n");
A: From microsoft documentation, you can create file if not exist and append to it in a single call
File.AppendAllText Method (String, String)
.NET Framework (current version) Other Versions
Opens a file, appends the specified string to the file, and then closes the file. If the file does not exist, this method creates a file, writes the specified string to the file, then closes the file.
Namespace: System.IO
Assembly: mscorlib (in mscorlib.dll)
Syntax
C#C++F#VB
public static void AppendAllText(
string path,
string contents
)
Parameters
path
Type: System.String
The file to append the specified string to.
contents
Type: System.String
The string to append to the file.
AppendAllText
A: using(var tw = new StreamWriter(path, File.Exists(path)))
{
tw.WriteLine(message);
}
A: .NET Core Console App:
public static string RootDir() => Path.GetFullPath(Path.Combine(AppContext.BaseDirectory, @"..\..\..\"));
string _OutputPath = RootDir() + "\\Output\\" + "MyFile.txt";
if (!File.Exists(_OutputPath))
File.Create(_OutputPath).Dispose();
using (TextWriter _StreamWriter = new StreamWriter(_OutputPath))
{
_StreamWriter.WriteLine(strOriginalText);
}
A: Please note that AppendAllLines and AppendAllText methods only create the file, but not the path. So if you are trying to create a file in "C:\Folder", please ensure that this path exists. | unknown | |
d12623 | train | You can add offline_access to your scope (e.g. "scope": "offline_access openid something:else",) and this will yield you a refresh_token.
Auth0 currently supports unlimited refresh_token usage, so when your access_token expires (you either can track expiration time manually using "expires_in": 86400 value in respones or react on 401 response from api) - you can send your refresh token to OAuth2 api endpoint and receive new access token back. They have few descent articles about this matter and what you need to configure for your clients and API as well as what not to do (depending on your client security assumptions).
Take a note - you must secure refresh_token properly - store it in some reliable store and prevent any external scripts from accessing it. I assume with electron app you can do it more reliable than with a public website. | unknown | |

UNION ALL
SELECT dn + 1
FROM week
WHERE dn < 7

SELECT DATENAME(dw, dn + 5)
FROM week
Replace dn + 5 with dn + 6 if your week starts from Monday.
If you need a single comma separated string instead of a set, use this:
WITH week (dn, dname) AS
(
SELECT 1, CAST(DATENAME(dw, 6) AS NVARCHAR(MAX))
UNION ALL
SELECT dn + 1, dname + ', ' + DATENAME(dw, dn + 6)

WHERE dn < 7
)
SELECT dname
FROM week
WHERE dn = 7
A: A straight select that will work with any SET DATEFIRST setting
select
datename(dw, 6-@@datefirst) + ', ' +
datename(dw, 1+6-@@datefirst) + ', ' +
datename(dw, 2+6-@@datefirst) + ', ' +
datename(dw, 3+6-@@datefirst) + ', ' +
datename(dw, 4+6-@@datefirst) + ', ' +
datename(dw, 5+6-@@datefirst) + ', ' +
datename(dw, 6+6-@@datefirst)
If you don't care about region (Monday or Sunday as first day of week), then just
select
datename(dw, 0) + ', ' + datename(dw, 1) + ', ' +
datename(dw, 2) + ', ' + datename(dw, 3) + ', ' +
datename(dw, 4) + ', ' + datename(dw, 5) + ', ' +
datename(dw, 6) + ', '
It will perform much better than going through CTE and will also work in 2000 should you ever need it.
A: The fastest means is to statically define the comma separated list. I don't know if SET DATEFIRST affects only the database -- if it's the entire instance, I would really hesitate to use SET DATEFIRST.
Rather than using recursion, you can use the values from MASTER..SPT_VALUES, and a combination of the STUFF and FOR XML PATH functions (Caveat: SQL Server 2005+):
Week starting on Sunday:
SELECT STUFF((SELECT ', ' + x.wkday_name
FROM (SELECT DISTINCT DATENAME(dw, t.number) AS wkday_name,
t.number
FROM MASTER.dbo.SPT_VALUES t
WHERE t.number BETWEEN -1 AND 5) x
ORDER BY x.number
FOR XML PATH ('')), 1, 2, '')
Week starting on Monday:
SELECT STUFF((SELECT ', ' + x.wkday_name
FROM (SELECT DISTINCT DATENAME(dw, t.number) AS wkday_name,
t.number
FROM MASTER.dbo.SPT_VALUES t
WHERE t.number BETWEEN 0 AND 6) x
ORDER BY x.number
FOR XML PATH ('')), 1, 2, '')
Comparison:
The statically defined list won't return a query plan for me on SQL Server 2005. Quassnoi's recursion example on 2005 has a subtree cost of 0.0000072; SPT_VALUES has a subtree cost of 0.0158108. So the recursive approach is appears more efficient than SPT_VALUES -- possibly due to the very small size? | unknown | |
d12626 | train | This can be done through R studio as well.
library(usethis)
usethis::edit_r_environ()
when the tab opens up in R studio, add this to the 1st line: R_MAX_VSIZE=100Gb (or whatever memory you wish to allocate).
Re-start R and/or restart computer and run the R command again that gave you the memory error.
A: I had the same problem, increasing the "R_MAX_VSIZE" did not help in my case, instead cleaning the variables no longer needed solved the problem. Hope this helps those who are struggling here.
rm(large_df, large_list, large_vector, temp_variables)
A: For those using Rstudio, I've found that setting Sys.setenv('R_MAX_VSIZE'=32000000000), as has been suggested on multiple StackOverflow posts, only works on the command line, and that setting that parameter while using Rstudio does not prevent this error:
Error: vector memory exhausted (limit reached?)
After doing some more reading, I found this thread, which clarifies the problem with Rstudio, and identifies a solution, shown below:
Step 1: Open terminal,
Step 2:
cd ~
touch .Renviron
open .Renviron
Step 3: Save the following as the first line of .Renviron:
R_MAX_VSIZE=100Gb
Step 4: Close RStudio and reopen
Note: This limit includes both physical and virtual memory; so setting _MAX_VSIZE=16Gb on a machine with 16Gb of physical memory may not prevent this error. You may have to play with this parameter, depending on the specs of your machine
A: I had this problem when running Rcpp::sourceCpp("my_cpp_file.cpp"), resulting in
Error: vector memory exhausted (limit reached?)

d12637 | train | The result you're getting from getPath() is the immutable value from a dict or list. This value does not even know it's stored in a dict or list, and there's nothing you can do to change it. You have to change the dict/list itself.
Example:
a = {'hello': [0, 1, 2], 'world': 2}
b = a['hello'][1]
b = 99 # a is completely unaffected by this
Compare with:
a = {'hello': [0, 1, 2], 'world': 2}
b = a['hello'] # b is a list, which you can change
b[1] = 99 # now a is {'hello': [0, 99, 2], 'world': 2}
In your case, instead of following the path all the way to the value you want, go all the way except the last step, and then modify the dict/list you get from the penultimate step:
getPath(["apple","colors",2]) = "green" # doesn't work
getPath(["apple","colors"])[2] = "green" # should work
A: You could cache your getPath using custom caching function that allows you to manually populate saved cache.
from functools import wraps
def cached(func):
func.cache = {}
@wraps(func)
def wrapper(*args):
try:
return func.cache[args]
except KeyError:
func.cache[args] = result = func(*args)
return result
return wrapper
@cached
def getPath(l):
...
getPath.cache[(someList, )] = 'green'
getPath(someList) # -> 'green'
A: You can't literally do what you're trying to do. I think the closest you could get is to pass the new value in, then manually reassign it within the function:
someData = {"apple":{"taste":"not bad","colors":["red","yellow"]}, "banana":{"taste":"perfection","shape":"banana shaped"}, "some list":[6,5,3,2,4,6,7]}
def setPath(path, newElement):
nowSelection = someData
for i in path[:-1]: # Remove the last element of the path
nowSelection = nowSelection[i]
nowSelection[path[-1]] = newElement # Then use the last element here to do a reassignment
someList = ["apple","colors",1]
setPath(someList, "green")
print(someData)
{'apple': {'taste': 'not bad', 'colors': ['red', 'green']}, 'banana': {'taste': 'perfection', 'shape': 'banana shaped'}, 'some list': [6, 5, 3, 2, 4, 6, 7]}
I renamed it to setPath to reflect its purpose better. | unknown | |

(Here, instead of b.Thing we will use String, and instead of a.Thing we will use Object; String is a subclass of Object, so it is analogous. Instead of a.Container, we will use List. The subclassing of the container is irrelevant, as you will see.) If you can understand why this example doesn't work, you will understand your problem.

d12646 | train | No you cannot do that. Parse the input and depending on the input, implement your logic with if statements for example. | unknown | |
d12647 | train | There is JsonField in postgres which can be used for this kind of tasks. Also there is many apps for django which add JsonField that can work with mysql like django-extensions for example
A: I'm not sure why you're avoiding subclassing, it's built pretty much for this purpose. The best way to do this is subclassing. For this example, it looks like you'd probably want to use the shape attribute as the major class. For example, you could create a Shape class thusly:
class Shape(models.Model):
color = models.CharField(max_length=20)
class Meta:
abstract = True
class Circle(Shape):
radius = FloatField()
class Ellipse(Shape):
eccentricity = FloatField()
This would create two tables in your model, a Circle table with a color and radius column, as well as a Ellipse table with a color and a eccentricity column.
If you really want to avoid subclassing for some reason, and you are using PostgreSQL, you can declare a JSONField (probably called attributes or something similar) of the different values. They would be harder to access programmatically, though. That would look like this:
class Shape(models.Model):
color = models.CharField(max_length=20)
attributes = models.JSONField() | unknown | |
d12648 | train | I recommend that you read the Data Binding Overview page on MSDN so that you can get a better idea on data binding. For now, I can give you a few tips. Firstly, in WPF, your property should really have used an ObservableCollection<T>, like this:
private ObservableCollection<Ligne> _ListeLigne = new ObservableCollection<Ligne>();
public ObservableCollection<Ligne> ListeLigne
{
get { return _ListeLigne; }
set
{
_ListeLigne = value;
OnPropertyChanged("ListeLigne");
}
}
Then your selected item like this:
private Ligne _CurrentLigne = new Ligne();
public Ligne CurrentLigne
{
get { return _CurrentLigne; }
set
{
_CurrentLigne= value;
OnPropertyChanged("CurrentLigne");
}
}
With properties like this, your XAML would be fine. Lastly, to add your items, you simply do this:
ListeLigne = new ObservableCollection<Ligne>(SomeMethodGettingYourData());
Or just...:
ListeLigne = SomeMethodGettingYourData();
... if your data access method returns an ObservableCollection<Ligne>. If you want to select a particular element in the UI, then you must select an actual item from the data bound collection, but you can do that easily using LinQ.
using System.Linq;
CurrentLigne = ListeLigne.First(l => l.SomeLigneProperty == someValue);
Or just:
CurrentLigne = ListeLigne.ElementAt(someValidIndexInCollection);
Oh... and I've got one other tip for you. In your code:
foreach (Ligne ligne in CurrentLigne)
{
if (Currentligne!= null) // this is a pointless if condition
_ligneBLL.InsetLigne(ligne);
}
The above if condition is pointless because the program execution will never enter the foreach loop if the collection is null.
A: Try This !!
foreach (Ligne ligne in ListLigne)
{
var _ligne = ligne as Ligne;
_ligneBLL.InsetLigne(ligne);
}
A: I think you want to use a BindingList. It is the list I always use, but remember you will need to post your notifyChange events. | unknown | |

d12650 | train | Although I'm not actually looking at Mikes code (you could do that though) I would imagine he has a single content control to which he has assigned the Front content originally. On Flip a projection is animated until its edge on at which point the Rear content is assigned, and the animation continues.
Hence at anyone time the only one of Front or Rear content can actually be navigated to with something like FindName
However if you give each of the root Child controls that you place in Front and Rear their own x:Name you should be able gain access to your text boxes using the rear name. | unknown | |
d12651 | train | I would recommend you to use composer, which will generate autoload.php for you to include at the top of the file:
#!/usr/bin/env php
<?php
require_once './vendor/autoload.php';
use Symfony\Component\ClassLoader\UniversalClassLoader;
$loader = new UniversalClassLoader();
$loader->registerNamespace('BlueHeadStudios', __DIR__.'/src/');
$loader->register();
// write your code below
A: You should run the application with app/console check the example here | unknown | |
d12652 | train | This makes sense because drawing to the canvas and clearing the canvas are expensive methods; if you have a smaller canvas and call clearRect on it every animation step then it will perform better than a larger canvas running the exact same code. The best thing to do is optimise your draw method to only clear what changed each frame. Once you do that you will notice a performance boost; this article will help with other areas in which you can increase performance.
I'm developing with canvas too and have found that WebKit based browsers, in general, handle canvas operations quicker than Gecko in most cases.
A: I actually see similar behavior. I believe it is when you cross the 65776 pixel barrier -> not 65536 as you would expect.
I don't yet know why this is the case, but it is likely some kind of internal data structure or data type issue (possibly its using a hash and needs to grow the table at that point) inside your browser. Your test is actually invalid on my chrome browser - it does not exhibit the same performance drop.
I wrote some test cases

d12654 | train | When people are using your react page, it is "running" on their computer and the software does not have access to all the files and data you'd like to use.
You will need to do this at "build time" when your service is being packaged up, or "on the server".
When you are building your react app, you can hook into processes that can find files and perform operations on them. Gatsby might be your best bet. Look at how people add "markup" files to their projects, built a menu from them and then render them as blog articles. NextJS, Vite, and other frameworks and tools will work, you may just need to learn a bit more.
The other approach, to do this "on the server" means when you are running code on the server you can do almost anything you like. So, your react app would make a call (e.g. rest request) to the server (e.g. NodeJS), and the code running on the server can use fs and other APIs to accomplish what you'd like.
From what you describe, doing this as part of your build step is probably the best route. A much easier route is to move this data into a JSON file and/or a database and not crawl the file system.
A: Looks like its a client side rendering app and not server side (node app). Resources folder you trying to list is residing in server and react app (javascript) running on browser can't access it directly.
A: To whom it may concern, I spent more time than I should have working on this. I highly recommend converting everything to JSON files and importing them. If you want to be able to scan for JSON files, make a JSON file that includes the names of all your files, then import that and use that for scanning. Doing things dynamically is a bare.
If you don't reformat, you'll likely need to use Fetch, which is asynchronous, which opens up a whole can of worms if you're using a framework like React.
If you're just importing json files, it's super easy:
import files from './resources/index.json';
where index.json looks like
{
"files":[
"file1.json",
"file2.json"
]
}
if you need to import the files more dynamically (not at the very beginning) you can use this:
var data = require('./resources/'+filename)
this will allow you to scan through your files using the index.json file, and load them dynamically as needed. | unknown | |

Then you need to register your activity.
mediaPlayer.setOnCompletionListener(this);
someView.setOnClickListener(this);
Where 'this' is the activity you just created
A: Stick this code right up at the start as part of the onCreate():
MediaPlayer mp = MediaPlayer.create(this, pathToTheFile, web, whereverTheSoundIs);
mp.setOnCompletionListener(this);
mp.start();
If that doesn't work, then you have a problem locating the sound file, or it is in the wrong format.
From experience, cut things down to simple parts and try and get each part working first before moving on.
Another thing I do is put comments after each } for example: '} // End of Case'
Oh, almost forgot, in the onCompletion you might like to close off the media player with
mp.release();

d12657 | train | This is an incredible stupid problem. The messages file is supposed to have the name messages_de_DE_XX.properties (note that the last two segments are in upper case).
My guess is it works when started from the IDE because Eclipse uses the filesystem and hence the OS standard, which is "ignore casing" for Windows.
When started from the finished product however the files are in JARs, where casing is important. | unknown | |

d12659 | train | __declspec(dllimport) tells the compiler that the function will be imported from a DLL using an import LIB, rather than found in a different OBJ file or a static LIB.
BTW: it sounds like you may not want DLLs at all. DLLs are specifically for swapping out the library after compilation without having to recompile the application, or for sharing large amounts of object code between applications. If all you want is to reuse a set of code between different projects without having to compile it for each one, static libraries are sufficient, and easier to reason about.
A: It's usually best to have a conditional macro that imports or exports depending
#ifdef MODULE1
#define MODULE1_DECL __declspec(dllexport)
#else
#define MODULE1_DECL __declspec(dllimport)
#endif
This way you export functions etc that you want to export, and import what you want to use.
For example see this SO post
You #define MODULE1 (maybe as a setting) in your project that will export definitions, and use the MODULE1_DECL define rather than explicitly putting either __declspec(dllimport) or __declspec(dllexport) in your code. Read the manual for further details.
Name mangling just happens in C++: it indicates namespaces, and the parameters a function overload etc. takes for disambiguation. | unknown | |

d12662 | train | It's not getting corrupted, you're just losing floating point precision as the magnitude of your number increases.
As your number gets larger and larger, the delta between each successive point gets larger as well.
In IEEE754, the difference between 1.f and the next larger number is 0.0000001
At 200,000, the next larger number is 200,000.02. (courtesy of IEEE754 converter). I'm not even 100% positive what kind of FP precision GLSL uses (the quick ref card indicates it might be 14-bit mantissa in the fragment shader?). So in reality it could be even worse.
If you're just looking at a small window of a large number, then the error will continue to grow. I suspect that as the precision goes down, your texture starts to look more and more 'blocky'.
The only thing I can think of to do is to design your code such that the number does not have to grow unbounded forever. Is there a smarter way you could wrap the number over so that it doesn't have to get so large? | unknown | |
d12663 | train | You can write your function to recode the levels - the easiest way to do that is probably to change the levels directly with levels(fac) <- list(new_lvl1 = c(old_lvl1, old_lvl2), new_lvl2 = c(old_lvl3, old_lvl4))
But there are already several functions that do it out of the box. I typically use the forcats package to manipulate factors.
Check out fct_recode from the forcats package. Link to doc.
There are also other functions that could help you - check out the comments below.
Now, as to why your code isn't working:
*
*df$col looks for a column literally named col. The workaround is to do df[[col]] instead.
*Don't forget to return df at the end of your function
*c(source = target) will create a vector with one element named "source", regardless of what happens to be in the variable source.
The solution is to create the vector c(source = target) in 2 steps.
revalue_factor_levels <- function(df, col, source, target) {
to_rename <- target
names(to_rename) <- source
df[[col]] <- revalue(df[[col]], to_rename)
df
}
Returning the df means the syntax is:
data <- revalue_factor_levels(data, "lg_with_children", "Mandarin", "Other")
I like functions that take the data as the first argument and return the modified data because they are pipeable.
library(dplyr)
data <- data %>%
revalue_factor_levels("lg_with_children", "Mandarin", "Other") %>%
revalue_factor_levels("lg_with_children", "Half and half", "Other") %>%
revalue_factor_levels("lg_with_children", "N/A", "Other")
Still, using forcats is easier and less prone to breaking on edge cases.
Edit:
There is nothing preventing you from both using forcats and creating your custom function. For example, this is closer to what you want to achieve:
revalue_factor_levels <- function(df, col, ref_level) {
df[[col]] <- forcats::fct_others(df[[col]], keep = ref_level)
df
}
# Will keep Shanghaisese and revalue other levels to "Other".
data <- revalue_factor_levels(data, "lg_with_children", "Shanghainese")
A: Here is what I ended up with thanks to help from the community.
revalue_factor_levels <- function(df, col, ref_level) {
df[[col]] <- fct_other(df[[col]], keep = ref_level)
df

d12667 | train | In the example the cache block size is 32 bytes, i.e., byte-addressing is being used; with four-byte words, this is 8 words.
Since an entire block is loaded into cache on a miss and the block size is 32 bytes, to get the index one first divides the address by 32 to find the block number in memory. The block number modulo 32 (5-bit index) is the index. The block number divided by 32 is the tag. The trace would look like this:
0 miss <00000, 0000, mem[0..31]>
4 hit <00000, 0000, mem[0..31]>
16 hit <00000, 0000, mem[0..31]>
132 miss <00100, 0000, mem[128..159]>
232 miss <00111, 0000, mem[224..255]>
160 miss <00101, 0000, mem[160..191]>
1024 miss <00000, 0001, mem[1024..1055]>
30 miss <00000, 0000, mem[0..31]>
140 hit <00100, 0000, mem[128..159]>
3100 miss <00000, 0011, mem[3072..3103]>
180 hit <00101, 0000, mem[160..191]>
2180 miss <00100, 0010, mem[2176..2207]>
As you can see there are four hits out of 12 accesses, so the hit rate should be 33%. (It looks like the provider of the answer thought there were 16 accesses.)
Side comment: Since this is starting from an empty cache, there is only one conflict miss (the mem[30] access) and the remaining seven misses are compulsory (first access) misses. However, if this was the body of a loop, in each iteration after the first there would be four conflict misses at index 00000 (address 0, 1024, 30, 3100), two conflict misses at 00100 (addresses 132, 2180), and six hits (addresses 4, 16, 140 are hits whose cache blocks have been reloaded in each iteration, corresponding to conflict misses; addresses 232, 160, 180 are hits whose cache blocks were loaded in the first iteration and not evicted).
Running through this trace, one can find that at the end the following blocks would be valid (being the last accessed for their index):
<00000, 0011, mem[3072..3103]>
<00100, 0010, mem[2176..2207]>
<00101, 0000, mem[160..191]>
<00111, 0000, mem[224..255]>
Note how this differs from the given answer which is clearly wrong because with 32-byte blocks, no block would start at mem[16] and 1024 divided by 32 gives a block number (in memory) of 32, 32 modulo 32 is 0 (not 1) for the index.
Incidentally, providing the byte range cached in the block is probably more helpful than just providing the starting address of the block. | unknown | |

A: What you can do is throw an exception in your GetBillingEntities method of your webservice. Catch the exception, log some details and then re-throw it. If your method throws an exception it should get caught in the "error:" block.
So basically you handle the error data in your service and handle how to display an error to the user in your "error:" block. | unknown | |

This way, you should be able to specify one gradient for whole LI content (in your case UL and LI). Strongly reccomend to use CSS3 gradients.
If this wont help you might need to specify on gradient for
#menu-top-navigation > li:hover {gradient color of XXX to YYY}
and one for

d12672 | train | The default model-binding setup supports an indexed format, where each property is specified against an index. This is best demonstrated with an example query-string:
?a[0].Number=1&a[0].Text=item1&a[1].Number=2&a[1].Text=item2
As shown, this sets the following key-value pairs

d12674 | train | There are a few errors in your code.
First of all, when you use single quotes in glob('$fileList/*'), it s literal string $fileList/*. There's no variable substitution.
If you want to put $fileList value into then string, you need to either use double quotes (glob("$fileList/*")), or concatenation (glob($fileList . '/*'))
Next error is that glob() returns array, so $fileList is an array, and that means that you cannot simply put it into a string.
Now, depending on what you really want to do, you may want to take any particular result from glob(), or iterate over all of them and do what you want on each of them.
I'll assume that you want to create index.html in each matched empty directory.
So it would be:
foreach($fileList as $filePath) {
if (count(glob("$filePath/*")) == 0 ) {
// rest of code
}
}
Now, there's the clue of your problem. Your putting content into index.html file in current directory, because you don't tell file_put_contents where to do it.
The first argument is path, not just the filename. So when you passed index.html value, it's a relative path to current directory.
You need to pass whole path, which probably is $filePath . "/index.html", so it would be:
$key = $filePath . "/index.html";
At the end I would like to notice, that you may need additional validation like if matched paths are indeed directories. Also working on relative paths is a little bit risky. It would be better to rely on absolute paths.
A: in line 3, instead of
$key = 'index.html';
you should use:
$key = $fileList[0].'/index.html';
It will create file in that folder not in current directory. | unknown | |

d12676 | train | If you have access to the server then you can create a directory using the glassfish server user.

d12677 | train | Here's how I resolved an issue in my context:
The server is run through an ANT script with jvm configured with an agent (the property name 'agentfile' below is associated with a value pointing to the agent library)
Now, I would get the error 'java result 1' whenever the server was run, without any indication of the actual error.
Here's how this issue was debugged.
1) The agent was turned off (i.e.) the above 2 lines were commented out.
2) Then when ANT was run, the actual error message was clearly shown - the problem was: a class file was missing. This error was being eaten by the agent, since it is low level C code and just looks to load a class that it cannot find and throws the Java error.
Lesson learnt: if you have an agent, turn it off and then run your ANT - it may throw up the reasons for error seen. This is of course one of many scenarios noticed for the java result 1 error. | unknown | |

A: Ok, so you can tell if the employee worked the night shift when his time_out was AM. In this case, it's the last row's case.
What I did was determinate a real date field. It is the day before when you're out from the night shift, and the current date in any other case
select empid,
IF(RIGHT(timeinout,2)='am' AND in_out='OUT',
DATE_ADD(date, INTERVAL -1 DAY),

group by empid, realdate
Outputs
depending on the table size it might be worth using this way just for saving yourself a join. In almost any other case, a join is cleaner.
I guess you have no control over the format of the input, so you'll have to stick to times as text and make a comparison for the am/pm suffix in the last 2 characters. I find that rather error prone, but let's pray the raw data will stick to that format.
This solution makes a few assumptions that I rather explain here to avoid further misunderstandings
*
*The workers can't work the night shift if they worked the day shift (since we're grouping by date, you would need an extra field to distinguish day shift and night shift for a given day)
*Input will never list an OUT time earlier than a IN time for a given day/employee tuple (if it happens, this would need an extra verification step to guarantee consistent output)
*Input will always include timein and timeout for a given shift (if it didn't, you would need an extra step to discard orfan timeentries).
A: Try this query and tell me if it works
SELECT empid,

d12679 | train | After testing with our other microservices, we found out that this problem was related to the elasticsearch-py library rather than our elasticsearch configuration, as our other microservice, which is golang based, could perform sniffing with no problem.
After further investigation we linked the problem to this open issue on the elasticsearch-py library: https://github.com/elastic/elasticsearch-py/issues/2005.
The problem is that the authorization headers are not properly passed to the request made to Elasticsearch to discover the nodes. To my knowledge, there is currently no fix that does not involve altering the library itself. However, the error message is clearly misleading. | unknown | |
d12680 | train | Other answers are assuming that you are already using a transaction. I won't omit this, since you might be missing it.
You should use a transaction to ensure that records in all 15 tables or none are inserted/updated. The transaction ensures you atomicity in your operation. If something fails during the stored procedure and you don't use a transaction, some of the save/update operations will be made, and some not (the ones from the query that has produced the error).
If you use BEGIN TRAN, and COMMIT for successful operations or ROLLBACK in case of failure, you will get all done or nothing. You should check for errors after each query execution, and call ROLLBACK TRANSACTION if there is one, or call COMMIT at the end of the stored procedure.
There is a good sample in the accepted answer of this Stackoverflow question on how to handle transaction inside a stored procedure.
Once you have the transaction, the second part is how to avoid dirty reads. You can set the isolation level of your database to READ COMMITED, this will prevent, by default, dirty reads on your data. But the user can still chose to do dirty reads by specifying WITH (NOLOCK) or READUNCOMMITED in his query. You cannot prevent that.
Besides, there are the snapshot isolation levels (Snapshot and Read Commited Snapshot) that could prevent locking (which is not always good), avoiding dirty reads at the same time.
There is a lot of literature on this topic over the internet. If you are interested in snapshot isolation levels, I suggest you to read this great article from Kendra Little at Brent Ozar.
A: You can't prevent that dirty read does not happen. Is the reader that does the dirty reads, not you (the writer). All you can do is ensure that your write is atomic, and that is accomplished by wrapping all writes in a single transaction. This way readers that do not issue dirty reads will see either all your updates, either none (atomic).
If a reader chooses to issue dirty reads there's nothing you can do about it.
Note that changing your isolation level has no effect whatsoever on the reader's isolation level.
A: All you need to do to ensure that the sql server isolation level is set appropriately. To eliminate dirty reads, it needs to be at Read Committed or higher, (Not at Read Uncommitted). Read Committed is the default setting out of the box.
It might be worth while, however, to review the link above and see what benefits, (and consequences) the higher settings provide.
A: You can set the transaction isolation level to SERIALIZABLE. by using the following statement
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
Before you BEGIN TRANSACTION but Warning it can slow down other user who will be try to see on update or insert data into your tables, Your can also make use of the SNAP_SHOT Isolation Level which shows you only the last Commited/Saved data but it makes extensive use of Temp DB which can also effect the performance. | unknown | |

d12684 | train | Are you just trying to mask the address, to make it look nicer or hide the fact that you're linking to to another website, or is it that you don't want people to know they can access that page without using your popup?
If it's the former, then what you could do is make the page you open in window.open an iframe, and point the iframe to your actual page. They user could still access the target page, but only via your nicer looking url.
The other option is to use something like a colorbox with an iframe instead of window.open, which will mask the address. Have a look at the Outside Webpage (iframe) example on this page.
Of course whichever option you choose, someone smart can still track down the target url via the source code and go there directly.

I guess you won't need most of them in JavaScript, which I am most familiar to and therefore it's "the language I'm thinking in".
Where you probably will need the hexadecimal radix is, when you want to convert a hexadecimal color code like #ffffff to an RGB color code.
The octal radix is useful regarding the Unix file permissions, but I read somewhere that it's deprecated in JavaScript. I can't imagine to have permission stuff running in JS anyway because would be a huge security issue. Or maybe just read only to output the permissions in the frontend.
I couldn't find anything why we should use a binary radix though. Maybe someone can add a comment. | unknown | |

d12690 | train | You can use .dropna(),.drop_duplicates().
parsed_data=parsed_data.drop.duplicates()
parsed_data.dropna(how='all', inplace = True)
# do operation inplace your dataframe and return None.
parsed_data= parsed_data.dropna(how='all')
# don't do operation inplace and return a dataframe as a result.
# Hence this result must be assigned to your dataframe
If directly .dropna() not working for you then you may use .replace('', numpy.NaN,inplace=True).
Or you can try this too:
json_df=json_df[json_df['SRC/Word1'].str.strip().astype(bool)]
This is faster then doing .replace(), if you have empty string.
And now we cleaned it, we can just use .values.tolist() to get those value in list.
A: Yup! Pandas has built-in functions for all of these operations:
import pandas as pd
df = pd.read_json('stela_zerrl_t01_201222_084053_test_edited.json', lines=True)
series = df['SRC/Word1']
no_dupes = series.drop_duplicates()
no_blanks = no_dupes.dropna()
final_list = no_blanks.tolist()
If you want an numpy array rather than a python list, you can change the last line to the following:
final_array = no_blanks.to_numpy()
A: Drop the duplicates, replace empty string by NaN, then create the list.
>>> df.drop_duplicates().replace('', np.NAN).dropna().values.tolist()
[['E1F25701'], ['E15511D7']]
PS: Since what you have is a dataframe so it will be a 2D List, if you want 1D list, you may do it for the specific column:
>>> df['SRC/Word1'].drop_duplicates().replace('', np.NAN).dropna().tolist()
['E1F25701', 'E15511D7']
What you have is not an empty string, but white space character, Try this: replace \s+ to np.NAN with regex=True:
>>>df['SRC/Word1'].drop_duplicates().replace('\s+', np.NAN, regex=True).dropna().tolist()
['E1F25701', 'E15511D7']

*Execute the following command in the command prompt:
mysqld.exe -u root --skip-grant-tables
*Leave the current MS-DOS command prompt as it is, and open a new MS-DOS command prompt window.

d12692 | train | Two solutions are here:
1) This is answer I get from Microsoft:
In the list view the WinJS.UI.GridLayout's viewport is loaded
horizontally.
You need to change the viewport's orientation to vertical. You can do
this by attaching the event onloadingstatechanged event.
args.setPromise(WinJS.UI.processAll().then(function () {
listview.winControl.onloadingstatechanged = function myfunction() {
if (listview.winControl.loadingState == "viewPortLoaded")
{
var viewport = listview.winControl.element.getElementsByClassName('win-viewport')[0];
viewport.className = 'win-viewport win-vertical';
}
}
}));
and change the class win-horizontal to win-vertical.
2) Problem could be also solved adding standard html header and list below header, without data-win-options="{ header: select('.header') }" attribute.
In that case we need to calculate height of the list:
.list {

d12693 | train | I figured it out - at least a hacked answer - and will post my solution in case others can use it.
Basically I adjusted the font size of the axis text, and used the scales pkg to keep the notation consistent (i.e. get rid of scientific). My altered code is:
ggplot(melt.df, aes(x = value)) +
geom_histogram(bins=50,na.rm=TRUE) +
facet_wrap(~variable, scales="free") +
theme_bw()+
theme(axis.text=element_text(size=10),text=element_text(size=16))+
scale_x_continuous(labels = scales::comma)
A: If you don't want the commas in the labels, you can set something like
options(scipen = 10)
before plotting. This makes the threshold for using scientific notation higher so ordinary labels will be used in this case. | unknown | |
d12694 | train | Generics with Bound Parameters (no wildcards)
*
*Is my inference correct as in ICommand definition?
No. Two reasons
*
*You have written a small 'o' while passing it to Mediator. (I guess it's just a typing mistake.)
*You passed IObserver<T> in stead of O to ISubject which would definitely cause a parameter bound mismatch.
Correct Version:
interface ICommand<T, M extends IMediator<T, S, O>, S extends ISubject<T, O>, O extends IObserver<T>>
*
*How to interpret the above case studies?
*
*The first thing you'd need to understand that you have one unknown type T and five interfaces.
*Therefore you would have total six concrete types which have to be included progressively in the interface declarations. (You explicitly asked not to bother about rationale of the design.)
*If you write them in a correct order, it becomes much more manageable.
Interface declarations:
interface IObserver<T>
interface ISubject<T, O extends IObserver<T>>
interface IMediator<T, O extends IObserver<T>, S extends ISubject<T,O>>
interface ICommand<T, O extends IObserver<T>, S extends ISubject<T, O>,
M extends IMediator<T, O, S>>
interface IProducerConsumer<T, O extends IObserver<T>, S extends ISubject<T, O>,
M extends IMediator<T, O, S>, C extends ICommand<T, O, S, M>>
*
*What are the best defintions assuming that I want to insert T and must able to get and put?
*
*If you want to get and put object of type T, what you probably need is bunch of interfaces which take only one parameter T. Generics will enforce that all would be compatible as T will be replaced by same type everywhere.
*Your current system is too rigid. In real scenario, you would never have so many implementations of these interfaces (unless you are re-implementing facebook in java) so that you'd have many possible combinations of the implementations and you want to ensure compatibility.
*Generics enforces type-safety by applying restrictions which are good. But you should not put restrictions just because you can put them. You are losing flexibility, readability and maintainability of your code.
*You should add bounds only when you need them. They should not affect the design in any way before contracts between interfaces have been decided.
Possibly sufficient way:
interface IObserver<T>
interface ISubject<T>
interface IMediator<T>
interface ICommand<T>
interface IProducerConsumer<T>
*
*What is the rules and relations of the type parameter definitions in interface and implemented classes?

*The only relation between type parameters in interfaces and implementing class that I can think of is that implementing class has to provide a type to replace the generic type parameter.
*In some cases, that type can again be a generic type in which case the responsibility of providing concrete type is forwarded to the code using the class reference or another class which extends that class. It may even be recursive!
*The rules are not written in the language, in stead, you are applying all the rules on this mechanism when you make any type parameter bound. So as long as you are supplying a type which qualifies against all of your rules, you are good to go.
*More rules means more robust but less flexible/readable. So do the trade of wisely.
Two simple cases:
// General way
private class ProductObserver implements IObserver<Product> { }
private ProductObserver productObserver;
// Aspect oriented way
private class LoggerObserver<T> implements IObserver<T> { }
private LoggerObserver<Product> loggerObserver;
*
*Lastly, I'd suggest you to read (comprehensive) Java Generics FAQ by Angelika Langer if you have any further doubt.
*If you keep experimenting like this, you might as well end up inventing a design pattern. Don't forget to share it with us when you do :D
Hope this helps.
Good luck. | unknown | |

d12696 | train | The issue you are seeing is because the pager savePages option is set to true by default.
In order for that option to work as expected, you need to include the storage widget, contained in the jquery.tablesorter.widgets.js file. Without the storage widget, the pager is not able to save the last user set page into local storage and/or cookies depending on browser support.
If you don't want the page to "remember" the last user set page size, then set that option to false:
$(function() {
$("table")
.tablesorter().tablesorterPager({
container: $("#pager"),
savePages: false,
size:5
});
}); | unknown | |

d12698 | train | Putting the two floats in there side by side makes the parent container's height effectively 0. You can put a div with a style="clear:both;" before the parent's closing tag and you will get your background back.
<div class="introduction">
<div class="image">
<img src="" />
</div>
<div class="text">
<p>
Text
</p>
<p>Good luck!!</p>
</div><div style="clear:both;"></div></div>
A: Something like this may achieve what you want:
<style>
.introduction{
margin:0px;
padding:5px;
background-color:orange;
}
.introduction img{
float:left;
padding:10px;
}
.introduction p{
padding-left:50px;
background-color:blue;
}
</style>
<div class="introduction">
<img src="img/can_25.png" />
<p>Text</p>
<p>Good Luck</p>
</div>
Since your p's aren't floated, they will hold your div open .. depending on the size of your image.
A: I would suggest you 2 solutions:
1) If you want to your output look like this:
IMAGE TEXT
IMAGE TEXT
TEXT
HTML:
<div class="whole">
<img class="ib" src="myimg.png" alt="my img" />
<p class="ib">my text my text my text my text my text my text my text is so short I will die alone</p>
</div>
CSS:
.ib{ display:inline-block;}
.whole{ vertical-align:top}
.ib img{width:30%; border:0;}
.ib p{width:70%;margin:0;padding:0;}
2) or like this:
IMAGE TEXT TEXT
TEXT TEXT
HTML:
<img src="myimg.png" alt="my img" class="leftimg" />
<p>my text my text my text is so short I will die alone</p>
CSS:
.leftimg {
float:left;
margin-right:5px;
}

d12699 | train | For points 1 and 2 you could try WxMpl :
http://agni.phys.iit.edu/~kmcivor/wxmpl/
It's a module for matplolib embedding in wxPython. Zooming in/out works out of the box. | unknown | |
d12700 | train | The first thing I would try, would be to double check that the python you're calling is the same that you've installed pygrib into
*
*$ which python
*$ python -c "help("modules")"
*$ python -c "help("modules pygrip")"
(to inspect which python you're calling, and which packages are installed there).
If that's not working, then there's something off with the ubuntu package - so I'd then try installing from source instead;
From https://github.com/jswhit/pygrib
Clone the github repository, or download a source release from https://pypi.python.org/pypi/pygrib.
Copy setup.cfg.template to setup.cfg, open in text editor, follow instructions in comments for editing. If you are using the old grib_api library instead of the new eccodes library, be sure to uncomment the last line setup.cfg.
Run 'python setup.py build'
Run 'python setup.py install' (with sudo if necessary)
Run 'python test.py' to test your pygrib installation. | unknown |
