d1501 | train | Try this:
notStrong = True
while notStrong:
digits = False
upcase = False
lowcase = False
alnum = False
password = input("Enter a password between 6 and 12 characters: ")
while len(password) < 6 or len(password)>12:
if len(password)<6:
print("your password is too short")
elif len(password) > 12:
print("your password is too long")
password = input("Please enter a password between 6 and 12 characters.")
for i in range(0,len(password)):
if password[i].isupper():
upcase = True
if password[i].islower():
lowcase = True
if password[i].isalnum():
alnum = True
if password[i].isdigit():
digits = True
if digits and alnum and lowcase and upcase and digits:
print("Your password is strong")
notStrong = False
elif (digits and alnum) or (digits and lowcase) or (digits and upcase) or (alnum and lowcase) or (alnum and upcase) or (lowcase and upcase):
print("Your password is medium strength")
else:
print("Your password is weak")
A: You don't have to make use of a loop, you can simply call the function within itself if the password is weak or medium, like so:
def Password():
digits = False
upcase = False
lowcase = False
alnum = False
password = input("Enter a password between 6 and 12 characters: ")
while len(password) < 6 or len(password)>12:
if len(password)<6:
print("your password is too short")
elif len(password) > 12:
print("your password is too long")
password = input("Please enter a password between 6 and 12 characters.")
for i in range(0,len(password)):
if password[i].isupper():
upcase = True
if password[i].islower():
lowcase = True
if password[i].isalnum():
alnum = True
if password[i].isdigit():
digits = True
if digits and alnum and lowcase and upcase and digits:
print("Your password is strong")
elif (digits and alnum) or (digits and lowcase) or (digits and upcase) or (alnum and lowcase) or (alnum and upcase) or (lowcase and upcase):
print("Your password is medium strength")
Password()
else:
print("Your password is weak")
Password()
Password()
This is a very useful technique and can be used to simplify many problems without the need for a loop.
Additionally, you can put in another check so that you can adjust the required strength of the password as needed in the future - this is not as easy to do (or rather, cannot be done as elegantly) if you use a while loop.
EDIT - To add to the advice given in the comments:
How does a "stack overflow" occur and how do you prevent it?

d1503 | train | subprocess.call() returns the exit code, not the stdout. You can use the Popen class directly:
nslookup_data = subprocess.Popen(["nslookup", clean_host], stdout=subprocess.PIPE).communicate()[0]
The .communicate()[0] at the end is important. That tells Popen that we are done, and it returns a tuple: (stdout, stderr). The first item in the tuple [0] is the stdout.
You could also use subprocess.check_output():
nslookup_data = subprocess.check_output(["nslookup", clean_host]) | unknown | |

d1505 | train | Personally i don't think you have much of an issue here - just apply the latest updates to the build server. The main reasons i say this are:
*
*it is highly unlikely that your code or any of the dependencies on the build server are so tightly coupled to the OS version that installing regular updates is going to affect anything, let alone break it. There can be minor differences between window messages etc between Windows versions, but those are few and far between, and are usually quite well documented out there on teh interweb. If you are using managed technology stacks like WPF/Silverlight or ASP.Net and even mostly Winforms then you will be isolated from these changes - they should only affect you if you are doing hardcore stuff using the WinAPI directly to create your windows or draw your buttons.
*it is a good practice to always engineer your product against the latest version of the OS, because you need to encourage your customer to implement those updates too - IOW you should not be in a position where you have to say to your client to not install update xyz because your application will not run against it - especially if that update is a critical security update
*testing for differences between OS versions should be done by the QA team and should independant of what is on the build server
*you do not want your build server to get in to such a state that it has been so isolated from the company update process that when you finally do apply them all it barfs and spits molten silicon everywhere. IOW, the longer you wait to update, the higher the risk of something going wrong and doing so catastrophically. Small and frequent/incremental updates are lower risk than mass updates once per decade :)
The build server updates that you do have to be cautious about are third party controls or library updates - they can frequently contain breaking changes or considerably altered behavior. They really should be scheduled, and followed up by a round of testing looking for any changes.
A: Virtualize!
Using stuff like VMWare Server you can script the launch and suspend of virtual machines. So you can script VM resume, SSH to launch build, copy, VM suspend, repeat. (I say this, but I abandoned my work on this. Still, I was making progress at the time.)
Also, you can trust your OS vendors. Can't you?
They have an interest in compatibility. If you build on Windows XP it is almost certain to work on XP SP3 and Vista and Windows 7.
If you build on RedHat Enterprise 5, it had better work on 5.1, 5.2, 5.3, 5.4, etc.
In my experience this has worked out OK so far for me and I recommend building on your lowest patch OS versions. With the Linux stuff in particular I have found newer releases linking to more recent libraries not available on older versions.
Of course it doesn't hurt to test your code on a copy of the deployment server. It all depends on how certain you want to be.
A: Take the build server off the network, that way you do not need to worry about installing security updates. Only load the source from CD, thumb drive or whatever other means.
Plug it back in at the end of your release cycle and then let all the updates take place.
A: Well, for the most stable process, I would have two build servers, "Build with Initial config, Build with update config", and two autotest test servers with similar differences. Use virtualization to do this effectively and scriptably. | unknown | |

d1509 | train | You are differentiating the self and other user by some uniqueness right, say for example uniqueness is user email or user id.
Solution 1:
On making socket connection, send the user id/email also and you can store that as part of socket object itself. So that when ever player1 did some move, on emit send the id also along with whatever data you are sending.
Solution 2:
When player1 did some move, you will send data to server, while sending the data, send the user id/email also. And in server again emit along with user id.
In client you can check - if id is self, then update at bottom. If id is not self then update the top. Note: If you have multiple opponent player, still you can handle with this.
EXAMPLE:
In client:
<script>
var socket = io();
var selfId;
socket.on('playerinfo', function(data){
selfId = data.name;
playerInfo = data.players;
$('.top').html(playerInfo);
$('.bottom')html(selfId);
});
socket.on('move', function(data){
if(data.uid == selfId)
{
$('.top').html(data.card);
}
else
{
$('.bottom')html(data.card);
}
});
socket.emit('move', {card:A, uid:56836480193347838764});
</script>
In server:
var players = [];
io.on('connection', function(socket){
//player is given 'P' with random number when connection is made to represent username
socket.name = "P" + Math.floor(Math.random() * (20000));
// Here may be you can assign the position also where the user is sitting along with the user name.
//players will be an array of object which holds username and their position
//So that in client you can decide where the user will sit.
players.push(socket.name);
io.emit('playerinfo', {'players':players, 'name':socket.name);
socket.on('move', function (data) {
socket.emit('move', data);
});

A: You need to give each client some kind of id, and tell each client when they connect, what their id is. When a client connects, generate a random unique id for them, and then send this back to them so they know their id. When you send back the data of other players, the client can figure out which data is theirs based on the id and display it in the right area. | unknown | |

d1512 | train | The way systemctl communicates with systemd to get service status is through a d-bus socket. The socket is hosted in /run/systemd. So we can try this:
docker run --privileged -v /run/systemd:/run/systemd -v /sys/fs/cgroup:/sys/fs/cgroup test-docker:latest
But when we run systemctl status inside the container, we get:
[root@1ed9d836a142 /]# systemctl status
Failed to connect to bus: No data available
It turns out that for this to work, systemctl expects systemd to be pid 1, but inside the container, pid 1 is something else. We can resolve this by running the container in the host PID namespace:
docker run --privileged -v /run/systemd:/run/systemd --pid=host test-docker:latest
And now we're able to successfully communicate with systemd:

d1513 | train | There are many challenges mixing different compilers, like:
*
*Name mangling (the way symbols are exported), especially when using C++
*Different compilers use different standard libraries, which may cause serious problems. Imagine for example memory allocated with GCC/MinGW malloc() being released with MSVC free(), which will not work.
With static libraries it is especially hard (e.g. malloc() can be linked to the wrong standard library).
With shared libraries there may be possibilities to solve these issues and get it to work, at least when sticking to C. For C++ it may be a lot more challenging. | unknown | |
d1514 | train | Yes, it is possible but your code would not work because x inside the loop will be unknown:

Possibly, you want to do something like:
for i in test_rng:

print(x)
my_fun2(x)
You may also want to double-check the code in my_fun1():
def my_fun1(i):
x=+i

as the use of x=+i may suggest you are trying to do something different from x = i, which is essentially what your code is doing: x=+i -> x = (+i) -> x = i
A: Your code contains a wrong logic and I am also assuming that the variable x is globally defined. See below.

d1517 | train | The server socket can bind only to an IP that is local to the machine it is running on (or, to the wildcard IP 0.0.0.0 to bind to all available local IPs). Clients running on the same network can connect to the server via any LAN IP/Port the server is bound to.
However, when the server machine is not directly connected to the Internet, but is running behind a router/proxy, the server socket cannot bind to the network's public IP. So, for what you are attempting, you need to bind the server socket to its local LAN IP (or wildcard) and Port, and then configure the network router to port-forward inbound connections from its public WAN IP/Port to the server's private LAN IP/Port. Then, clients running on other networks can connect to your public WAN IP/Port, and then be forwarded to the server.
If the router supports UPnP (Universal Play-by-play) and it is enabled, the server code can programmably setup the port forwarding rules dynamically. Otherwise, the rules need to be configured manually in the router's configuration by an admin. | unknown | |

A: Answer #1: Map localhost in your hosts file, as I linked to earlier. Just to be sure.
Answer #2: If you're using shared memory, bit-size could easily become an issue. Make sure you're using the same word width everywhere.
A: In order to debug application follow this steps:
Open the application on the device.
Find the PID with jdwp (make sure that 'android:debuggable' is set to true in the manifest):
adb jdwp
Start JVM with the following parameters:
java -agentlib:jdwp=transport=dt_shmem,server=y,address=<port> <class>
Expected output for this command:
Listening for transport dt_shmem at address: <port>
Use jdb to attach the application:
jdb -attach <port>
If jdb successful attached we will see the jdb cli.
Example:
> adb jdwp
12300
> java -agentlib:jdwp=transport=dt_shmem,server=y,address=8700 com.app.app

d1524 | train | Try to use a UIToolBar instead of a UIVisualEffectView as the background of the segment. The navigation bar has translucent background rather than blur effect. UIToolBar has the same translucent background as navigation bar, so it would look seamless at the edge.
A: Looking to your picture it seems your issue is not attributable to UINavigationBar but to a view where you have added UISegmentedControl.
I don't know your structure but it could be the tableHeaderView (self.tableView.tableHeaderView) so a reasonable way to solve this problem is to change the header color:

I like pandas because it takes your data without having to do any manipulation to it and plot it.
A: You can access the keys of a dictionary via dict.keys() and the values via dict.values()
If you wanted to plot, say, the data for 2013 you can do:
import matplotlib.pyplot as pl
x_13 = data['2013'].keys()
y_13 = data['2013'].values()
pl.bar(x_13, y_13, label = '2013')
pl.legend()
That should do the trick. More elegantly, do can simply do:
year = '2013'
pl.bar(data[year].keys(), data[year].values(), label=year)
which woud allow you to loop it:
for year in ['2013','2014','2015']:
pl.bar(data[year].keys(), data[year].values(), label=year)
A: You can do this a few ways.
The Functional way using bar():
data = {'2013': {1: 25, 2: 81, 3: 15}, '2014': {1: 28, 2: 65, 3: 75}, '2015': {1: 78, 2: 91, 3: 86}}
df = pd.DataFrame(data)
X_axis = np.arange(len(df))
plt.bar(X_axis - 0.1,height=df["2013"], label='2013',width=.1)
plt.bar(X_axis, height=df["2014"], label='2014',width=.1)
plt.bar(X_axis + 0.1, height=df["2015"], label='2015',width=.1)
plt.legend()
plt.show()
More info here.
The Object-Oriented way using figure():
data = {'2013': {1: 25, 2: 81, 3: 15}, '2014': {1: 28, 2: 65, 3: 75}, '2015': {1: 78, 2: 91, 3: 86}}

d1527 | train | boost::mpl::_1 and boost::mpl::_2 are placeholders; they can be used as template parameters to differ the binding to an actual argument to a later time. With this, you can do partial application (transforming a metafunction having an n-arity to a function having a (n-m)-arity), lambda expressions (creating a metafunction on-the-fly where it is needed), etc.
An expression containing at least a placeholder is a placeholder expression, which can be invoked like any other metafunction, with some arguments that will replace the placeholders.
In your example, assuming the following typedef
typedef boost::flyweights::hashed_factory_class<
boost::mpl::_1,
boost::mpl::_2,
boost::hash<boost::mpl::_2>,
std::equal_to<boost::mpl::_2>,
std::allocator<boost::mpl::_1>
> hashed_factory;
we can assume that at some other point in the code, the hashed_factory will be invoked with some parameter:
typedef typename
boost::mpl::apply<
hashed_factory,
X,
Y
>::type result; // invoke hashed_factory with X and Y
// _1 is "replaced" by X, _2 by Y
I did not look in Flyweight code, but we can suppose that _1 will be bound to the value type of the flyweight, and _2 to the key type (since it is used for hashing and testing equality). In this case, I think both will be std::string since no key type is specified.
I'm not sure my explanation about MPL's placeholders is quite clear, feel free to read the excellent MPL tutorial that explains very well metafunctions, lambda expressions and other template metaprogramming features. | unknown | |

d1532 | train | You need to make sure that you #include the right headers, in this case:
#include <stdlib.h> // rand(), srand()
#include <time.h> // time()
When in doubt, check the man pages:
$ man rand
$ man time
One further problem: time() requires an argument, which can be NULL, so your call to srand() should be:
srand(time(NULL));
A: Note that time() function uses current time (expressed in seconds since 1970) both in its return value and in its address argument.
A: I had this issue, and the problem was that in windows you need to include sys/time.h, but in linux you need time.h and I didn't notice.
I fixed this by adding a simple platform check:
#ifdef _WIN32
#include <sys/time.h>
#else
#include <time.h>
#endif
Note that this is for windows and linux, because that's what I needed for my program. | unknown | |
d1533 | train | person['age'] = age
The 'age' inside the brackets is the key, the value 'age' is where your value is assigned.
The person dictionnary becomes:
{'first': first_name, 'last': last_name,'age': age}
A: Here, person[age] = age
works only when age is given as argument when calling this function.
person is dictionary, age in person[age] is key, and the age which is at right side of assignment operator(=) is value passed as argument in function.
for e.g :
for the given code below in last line i have given age as argument.
def build_person(first_name, last_name, age=None):
person = {'first': first_name, 'last': last_name}
if age:
person['age'] = age
print(person)
return person
build_person("yash","verma",9)
Output for above code is :
{'first': 'yash', 'last': 'verma', 'age': 9}
now,
if i don't give age as a argument then,
def build_person(first_name, last_name, age=None):
person = {'first': first_name, 'last': last_name}
if age:
person['age'] = age
print(person)
return person
build_person("yash","verma")
output will be:
{'first': 'yash', 'last': 'verma'} | unknown | |
d1534 | train | If a variable is declared, but not initialized, its value will be Empty, which you can check for with the IsEmpty() function:
Dim banners
If IsEmpty(banners) Then
Response.Write "Yes"
Else
Response.Write "No"
End If
' Should result in "Yes" being written
banners will only be equal to Nothing if you explicitly assign it that value with Set banners = Nothing.
You will have problems, though, with this technique if you have Option Explicit turned on (which is the recommendation, but isn't always the case). In that case, if banners hasn't been Dimed and you try to test IsEmpty(banners), you will get a runtime error. If you don't have Option Explicit on, you shouldn't have any problems.
edit: I just saw this related question and answer which might help, too.
A: @Atømix: Replace
If Not banners Is Nothing then
and use
If IsObject(banners) Then
Your other code you can then place into an include file and use it at the top of your pages to avoid unnecessary duplication.
@Cheran S: I tested my snippets above with Option Explicit on/off and didn't encounter errors for either version, regardless of whether Dim banners was there or not. :-)
A: IsObject could work, but IsEmpty might be a better option - it is specifically intended to check if a variable exists or has been initialised.
To summarize:
*
*IsEmpty(var) will test if a variable exists (without Object Explicit), or is initialised
*IsNull(var) will test if a variable has been assigned to Null
*var Is Nothing will test if a variable has been Set to Nothing, but will throw an error if you try it on something that isn't an object
*IsObject(var) will test if a variable is an object (and will apparently still return False if var is Empty).
A: Somewhat related is IsMissing() to test if an optional parameter was passed, in this case an object, like this:
Sub FooBar(Optional oDoc As Object)
'if parameter is missing then simulate it
If IsMissing(oDoc) Then Dim oDoc as Object: oDoc = something
...
A: You need to have at least dim banners on every page.
Don't you have a head.asp or something included on every page?
A: Neither of IsEmpty, Is Object, IsNull work with the "Option Explicit" Setting, as stealthyninja above has misleadingly answered.
The single way i know is to 'hack' the 'Option Explicit' with the 'On Error Resume Next' setting, as Tristan Havelick nicely does it here:

d1538 | train | Re: best ways to organize jQuery libraries, you should start by reading the Plugins Authoring article on jquery.com:
http://docs.jquery.com/Plugins/Authoring
A: Notes:
*
*Namespacing is a good practice because you have less chance of having conflicting names with other scripts. This way, only your name-space has to be unique, but multiple name-spaces can have the same functions in them.
*jQuery DOES use namespacing, and you do not need the plug-in. The jQuery object itself is a name-space. . . Any function inside jQuery is 'name-spaced' in the jQuery object. This is true for any JavaScript object.
In response to Amir's comment:
YUI achieves namespacing by adding a variable to the YUI object where the added variable is also an object. Their namespace function just builds it for you.
var lib = {
util:{},
widget:{},
tool:{}
};
//creates a function named reset in the lib.util namespace
lib.util.reset = function() {};
//creates a function named reset in the lib.widget namespace
lib.widget.reset = function() {};
In jQuery, you add it to the jQuery.fn (or $.fn if you use $ for jQuery() namespace.
A: require.js is a better practice because it doesn't require you to add objects onto the window object unnecessarily. It also doesn't mean you have to worry about the loading order of previous javascript files. | unknown | |

d1553 | train | When you create HTTP(S) Load Balancer, there should be a Certificate section in Frontend configuration if you set the protocol to HTTPS, also preserve a static IP. Then you can configure the DNS to point the domain to this IP. | unknown | |
d1554 | train | Spring will only handle injection dependencies to a class that is constructed by the container. When you call getInstance(), you are allocating the object itself... there is no opportunity there for Spring to inject the dependencies that you have @Autowired.
Your second solution works because Spring is aware of your LovHelper class; it handles constructing it and injecting it into your other class.
If you don't want to mark the class with@Component, you can declare the class as a bean directly in your XML configuration. If you don't want to have it be a singleton, you can set it with prototype scope.
If you really need to manage the class yourself, you could consider looking at @Configurable. I believe it is intended to solve this problem but it requires aspects and I have not played with it myself.
A: Your helper should be context aware, but you can make it static:
@Component
public class LovHelper {
private static LovHelper instance;
@PostConstruct
void init() {
instance = this;
}
// do stuff
In this case static instance will keep reference to Spring aware bean. | unknown | |

A: You can use var rootFolder = Server.MapPath("~") to retrieve the physical path.
The tilde character ~ is replaced with the root directory of your web application, e.g. c:\installation\path\web_app

d1558 | train | To "append" to numbers, you need to convert them to strings first with str(). Numbers are immutable objects in Python. Strings are not mutable either but they have an easy-to-use interface which makes it easy to create modified copies of them.
number = 345
new_number = int('2' + str(number))
Once you are done editing your string, you can easily convert it back to an int with int().
Note that strings don't have an append method like lists do. You can easily concatenate strings with the + operator however.
A: As @Fredrik comments, you can get from any integer to any other integer by a single addition - and this is how you should probably do it, if you deal with integers only.
>>> i = 345
>>> 2000 + i
2345
There are, however, many way to express "prepend a 2 to 345", one would be to use format:
>>> '2{}'.format(345)
'2345' | unknown | |

if(count ($emails)<3)
{
if(filter_var_array($emails, FILTER_VALIDATE_EMAIL))

A: You could check the number of email in the string like this:
if(count(explode(';',$emailList))<3)
{
// send email
}
else
{
// Oh no, jumbo!
}
This code will explode your email string based on the ; characters into an array while at the same time use a count function on the array and execute one of two scenarios based on the number.
A: This should work to only pick maximum two emails (the first two):
$emailString = "email@examplecom;[email protected];[email protected]";
$emails = explode(";", $emailString);
$emails = array_slice($emails, 0, 2);
$emailString = implode(";", $emails);
var_dump($emailString);

d1560 | train | Many people don't realise that the DOM is not thread-safe (even if you are only doing reads). If you are caching a DOM object, make sure you synchronize all access to it.
Frankly, this makes DOM unsuited to this kind of application. I know I'm biased, but I would suggest switching to Saxon, whose native tree implementation is not only far faster than DOM, but also thread-safe. One user recently tweeted about getting a 100x performance improvement when they made this switch. | unknown | |
d1561 | train | Approach 1 :
4 different servers, mean four different URLs ok.
suppose ur application url is
http(s)://ipaddress:port/application
now it is possible that all four server instances are on same machine. in that case "ipaddress" would be same. but port would be different. if machines are different in that case both ipaddress and port would be different.
now inside your code you can get absoultepath. absolutepath would consist of the complete URL of the file absolutepath is requested on. like
http://ipaddress:port/application/abc/def/x.java.
Now from this you can extract the port/ipaddress and write your logic.
Approach2:
have a property file inside your application that contains the server its being deployed on. ( right now I cant think of something to set this automatically, but while deployment you can set the server name in this property file)
later on when you need. you can read the property file and you will know which version of application you are running on.
personally I`d prefer approach2 (and should be prefered in case we can think of initializing the properties file automatically)
Hope it helps :-) | unknown | |
d1562 | train | getElementbyName gets an element by its name.
The reference attribute:
*
*Is not a name attribute
*Is not valid HTML at all
So start by writing valid HTML:
<div id="123" data-reference="r045">
Then get a reference to that element:
const div = document.getElementById('123');
Then get the data from it using the dataset API:
console.log(div.dataset.reference);
Live demo
const div = document.getElementById('123');
console.log(div.dataset.reference);
<div id="123" data-reference="r045"></div>
A: You can use document.querySelectorAll('[reference]') if you have multiple div with same attribute.
var reference = document.querySelectorAll('[reference]');
console.log(reference);
<div id="123" reference="r045"></div>
But if you have only one div with reference attribute then use querySelector:
var reference = document.querySelector('[reference]');
console.log(reference);
<div id="123" reference="r045"></div>
A: var reference = document.getElementById("123").getAttribute("reference");

d1563 | train | Instead of / additional to naming your labels by specific names you can later match them on, I'd think a Map of JLabels with Strings or Integers as keys might be a better approach:
Map<String,JLabel> labelMap = new HashMap<String,JLabel>();
labelMap.put("1", OP_1);
labelMap.put("2", OP_2);
This will allow later access of "The label for key 2" as well as "list me all that labels and find the one with text 2" as well
A: Here I created an array of JLabels and a method, updateNextLabel(String), which will update the next JLabel with whatever you enter for str.

//Here is an example if you wanted to use a for-loop to update the JLabels
for (int x = 0; x < array.length; x++) {
updateNextLabel("This is the new text for OP" + (count + 1));
System.out.println(array[x].getText());

d1566 | train | Well, I don't think you following the guidelines when you're using images. The android documentation doesn't say anything about screen resolutions when dealing with images, it rather focuses on pixel density when referring image resources (usually drawables) which is explained here. Remember that you can have two types of images (as far as I know):
*
*Image resources (usually drawables)
*Image assets
When using drawables you have to focus on pixel density rather than screen resolution because as you have just found out a small (or regular) screen device can have exactly the same resolution as a large screen device, to top it off, sometimes a normal screen device (handset) can have a higher resolution than a large screen device (tablet) where obviously in this case the handset has a much higher pixel density. So, you need to follow their guidelines take a medium pixel density (mdpi) device as the baseline to design your image resources as follows...taking a 96px image as an example...
*
*for a medium density device (mdpi) provide an image with 96px in the drawable folder...this is your baseline
*then, target a high pixel density(hdpi) device by multiplying your baseline image by 1.5...that is, 96x1.5 = 144px...place this image inside the drawable-hdpi folder with exactly the same name
*a x-large pixel density device image would be the baseline image multiplied by 2 (96x2=192px). This goes inside the drawable-xhdpi folder
*for an xx-large picel density (xxhdpi) device multiply the baseline image by 3 (96x3=288) and place it inside the drawable-xxhdpi folder
Notice in the link provided that you don't need to provide an image for a device with a low pixel density since Android scales it down from mdpi without any problems...
Note: Android also supports low-density (LDPI) screens, but you normally don't need to create custom assets at this size because Android effectively down-scales your HDPI assets by 1/2 to match the expected size.
In your case, whats happening is that your Galaxy tablet has a lower pixel density and Android down-scales the image from a xxhdpi to whatever density the tablet has (hdpi or xhdpi)....so, it your image is a 512px image Android would down-scale it to 341px for xhdpi or 256px for an hdpi device.
If you follow these guidelines and focus on pixel density, you should be fine. However, for images in the assets folder there's no much you can do apart from using the ScaleType enum or using stretchable 9-patch images
Hope this helps
Update
Actually, according to this link, the Galaxy Tab 2 has mdpi screen, which means your image will be scale down three times from xxhdpi. You should provide the same images with different sizes inside the appropriate drawable-x folders
A: I know its a way too late but recently I faced the same issue about the way app launcher icons looks on a tablet and they are blurry. I'm sure that AOS honestly chooses mdpi drawables for tablets with mdpi display density and thats the problem. So I solved this by placing smartphones icons to a tablet resources dirs as following (left column - usual smartphone drawables-density and the right - tablet dirs):
drawable-xhdpi -> drawable-large-mdpi (these are 96x96px)
drawable-xxhdpi -> drawable-large-hdpi (these are 144x144px)
drawable-xxxhdpi -> drawable-large-xhdpi (these are 192x192px)
drawable-xxxhdpi -> drawable-xlarge (these are 192x192px)
I'm not sure if last two has to be 288x288 px but since I don't have such icons in the project I guess 192x192 should be enough. | unknown | |
d1567 | train | Your ThreadPoolTaskExecutor has too many threads. CPU spend lot of time to switch context between threds. On test you run just your controller so there are no other threads (calls) that exist on production. Core problem is waiting for DB, because it is blocking thread
Solutions
*
*set pool size smaller (make some experiment)
*remove executor and use actor system like Akka for save operation.
*Most important use batch to save objects in DB. There will be only one call per e.g. 1000 objects not 1k calls for 1k objects > JPA/Hibernate improve batch insert performance
A: It looks like you are turning the wrong knob.
In your first version you had up to N threads banging your database. With N being configured somewhere in your servlet container. And also doing the servlet thingy, accepting connections and stuff.
Now you created 200 additional threads, which do basically nothing but hitting the database. While the previous threads do their connection handling, request parsing thing. So you increased the load on the database and you added the load do to context switching (except when you have multiple hundred cores).
And for some weird reason, your database didn't get any faster.
In order to improve, reduce the number of threads in your thread pool which hits the database. Measure how many threads the database can handle before performance degrades.
Make the queueCapacity large enough to cover the request spikes you need to handle.
Implement something that gets a meaningfull answer to the user when this isn't sufficient. Something like "Sorry ..."
And then take care of the real issue: How to make your database handle the requests fast enough.
It might be that some db tuning is in place, or you need to switch to a different database system, or maybe the implementation of the save method needs some tuning ...
But all this is for a different question.
A: the bottle neck in your case are transactions (DB)
here's some proposals :
*
*if it's not necessary that data has to be instantly saved just use an asynchronous job to do it (JMS, In Memory Queue, etc)
*You may consider to load DB into RAM | unknown | |

d1575 | train | The position does not change! If you look closely at your linked images, you'll see that your fingerpainting does not move relative to the corner of the photo. In other words, you are saving the drawings' positions relative to the screen rather than relative to the current scroll position of the photo.
When you save, you have to take into account the fact that the background photo is cropped and/or scaled.
A: Maintain a paint/erase mode. When in paint/erase mode, disallow panning and zooming. When paint/erase is turned off, get the drawing cache and set it to imageview. Now the changes are permanently in the bitmap. So you can pan/zoom now and again enter the paint/erase mode to edit further. | unknown | |
d1576 | train | You're not showing us your connection string, but I'm assuming you're using some kind of AttachDbFileName=.... approach.
My recommendation for this would be: just don't do that. It's messy to fiddle around with .mdf files, specifying them directly by location, you're running into problems when Visual Studio wants to copy that file around - just forget about all that.
I would
*
*create the database on the SQL Server Express instance (CREATE DATABASE ..... in Mgmt Studio)
*talk to the database by its logical name - not a physical file name
So I would put my database onto the SQL Server Express server instance, and then use a connection string something like this:
Server=.\SQLEXPRESS;Database=MyShinyDatabase;Integrated Security=SSPI;
No messy file names, Visual Studio won't have to copy around files at runtime or anything, your data is on the server and can be used and administered there - seems like the much cleaner and much nicer approach to me. | unknown | |

d1580 | train | You should manually keep track of all "forms" in a list somewhere, then just iterate over that list and close them.
If for whatever reason this is not possible you could use JFrame.getWindows() which accesses all Windows in the application
for (Window each : JFrame.getWindows()) {
each.setVisible(false);
}
Note: This may not properly shutdown the forms, e.g. remove listeners/stop threads the forms may be using... | unknown | |
d1581 | train | You must first extract the number from the string. If the text part ("R") is always separated from the number part by a "|", you can easily separated the two with Split:
Dim Alltext_line = "R|1"
Dim parts = Alltext_line.Split("|"c)
parts is a string array. If this results in two parts, the string has the expected shape and we can try to convert the second part to a number, increase it and then re-create the string using the increased number
Dim n As Integer
If parts.Length = 2 AndAlso Integer.TryParse(parts(1), n) Then
Alltext_line = parts(0) & "|" & (n + 1)
End If
Note that the c in "|"c denotes a Char constant in VB.
A: An alternate solution that takes advantage of the String type defined as an Array of Chars.
I'm using string.Concat() to patch together the resulting IEnumerable(Of Char) and CInt() to convert the string to an Integer and sum 1 to its value.
Raw_data = "R|151"
Dim Result As String = Raw_data.Substring(0, 2) & (CInt(String.Concat(Raw_data.Skip(2))) + 1).ToString
This, of course, supposes that the source string is directly convertible to an Integer type.
If a value check is instead required, you can use Integer.TryParse() to perform the validation:
Dim ValuePart As String = Raw_data.Substring(2)
Dim Value As Integer = 0
If Integer.TryParse(ValuePart, Value) Then
Raw_data = Raw_data.Substring(0, 2) & (Value + 1).ToString
End If
If the left part can be variable (in size or content), the answer provided by Olivier Jacot-Descombes is covering this scenario already.
A: Sub IncrVal()
Dim s = "R|1"
For x% = 1 To 10
s = Regex.Replace(s, "[0-9]+", Function(m) Integer.Parse(m.Value) + 1)
Next

A: I found a workaround. I had the page check to see if it was set to no-pic.png and then it displays a no-pic.png in another location. That way when it goes to upload a picture, it won't delete it. :) Thanks for your help though. | unknown | |
d1583 | train | What Animations are you using? I tried it with a TranslateAnimation and RotateAnimation, it is working. Also where are you calling the startAnimations from? | unknown | |
d1584 | train | You don't really need regexp for this.
select(.value | ascii_downcase == "[email protected]") .id
But if you insist on it, below is how you perform a case-insensitive match using test/2.
select(.value | test("[email protected]"; "i")) .id | unknown | |
d1585 | train | The problem is here:
"consumes": []
The consumes keyword specifies the Content-Type header in requests. Since you are POSTing form data, it should be:
"consumes": ["application/x-www-form-urlencoded"]
Tip: You can paste your spec into http://editor.swagger.io to check for syntax errors. | unknown | |
d1586 | train | You can use string_to_array along with unnest to break your data into first an array and then separate rows.
select * FROM (
select name, date, unnest(string_to_array(data, '|')) as data from stuff
) AS sub
WHERE sub.data != '';
The WHERE clause is required to remove the empty strings at the beginning and end of your data. | unknown | |
d1587 | train | I don't know what the QByteArray type is, but I'll wager that it is an array of signed characters. As a result, when the high bit of a byte is a one, that sign bit is extended when converted to an integer which all gets exclusive-or'ed into your CRC at crc ^= (quint16)buf[pos];. So when you got to the 0xdf, crc was exclusive-or'ed with 0xffdf instead of the intended 0xdf.
So the issue is not the length, but rather the likelihood of having a byte with the high bit set.
You need to provide unsigned bytes, or fix the conversion, or do an & 0xff to the resulting byte before exclusive-or'ing with the CRC. | unknown | |
d1588 | train | The upshot is I was trying to find a cell in a table that was about to be presented. I wanted to set the table's accessibilityIdentifier to make it easier to find. After Googling to confirm it needed to be done in code rather than IB, I found a post suggesting I also needed to set
tableView.isAccessibilityElement = true
I didn't realise it all stopped working the minute I did that, because I made other changes as well. Once this property was set, I could no longer find any cells/staticTexts within the table. When I commented the code out, it all started magically working again, including recording tests. | unknown | |
d1589 | train | To use AVG() or any sort of aggregate functions in SQL, you need to have a GROUP BY for the other columns you're displaying.
Think of it this way, when you SELECT a column, you display rows. When you show an average, you show a single output. You can't put rows and a single output together.
You'll need to try something along the lines of:
SELECT col1, col2, AVG(col3)
FROM table1
GROUP BY col1, col2
A: I created a fiddle with your example, and you can see that the query as it is works. It is probably an error in a wrapping query, store procedure or function. | unknown | |
d1590 | train | You can create a "custom wrapper" for JMockit's @Tested annotation (ie, use it as a meta-annotation), but not for any of the other annotations, @Mock included. So, the answer is no, it's not possible. | unknown | |
d1591 | train | now, I found myself a solution to my problem. There I, do not use CGI but PHP an Pyton. Certainly, this solution is not very elegant, but it does what I want. In addition, I must perform some MySQL queries. All in all I can by the way increase the performance of the whole page.
My Code now looks like this:
index.html
<html>
<head>
<title>TEST</title>
<script src="jquery.js"> </script>
</head>
<body>
<script>
function ButClick(){
var TestVar = "'Hallo! This is a test'";
$.post('test.php',{var:TestVar},function(response) $('#TestDiv').html(response)});
}
</script>
<form><input type='button' onclick="ButClick()" value="Click Me!" /></form>
<div id='TestDiv'></div> </body>
</body>
</html>
test.php
<?php
$param1=$_POST['var'];
$command="python test.py $param1 $param2";
$buffer='';
ob_start(); // prevent outputting till you are done
passthru($command);
$buffer=ob_get_contents();
ob_end_clean();
echo "PHP and".$buffer;
?>

d1592 | train | I just put the following in my parent activity in the onCreate ..., then used a public interface like Rarw mentioned above.
gesturedetector = new GestureDetector(new MyGestureListener());
myLayout.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
bTouch = true;
return false;
} else {
gesturedetector.onTouchEvent(event);
bTouch = false;
return true;
}
}
});
And added the following to my parent activity and a gesturedetector to catch the desired events.
public boolean dispatchTouchEvent(MotionEvent ev) {
super.dispatchTouchEvent(ev);
return gesturedetector.onTouchEvent(ev);

d1593 | train | Update your rowDrag definition in the name column definition to the following:

Demo. | unknown | |
d1594 | train | You can always change that field to:
upload = models.DateTimeField(auto_now_add=True, null=True)

A: there are some issues in the code...
*
*Firstly the method decoration with WebInvoke is usually done in the
interface not in main class
*Second is the method name (test) and the UriTemplate="/Test" should be
same. It should be like as follows
*UriTemplate="/Test"
public string Test(string a, string b)
{
string myJsonString = (new JavaScriptSerializer()).Serialize("Hello World! A: " + a + " b: " + b);
return myJsonString;
}
*There is an issue where you do an ajax call to this method
Replace the following line
url: "http://localhost/PasswordResetter/Resetter.svc"
with
url: "http://localhost/PasswordResetter/Resetter.svc/Test"
Hope this will help.... | unknown | |
d1596 | train | since you pass getLastImportTime function to when helper method, it should explicitly return a promise, (but in getLastImportTime() you are returning nothing and when() is expecting you to pass a promise) otherwise the helper could evaluate it as an immediate resolved (or rejected) promise.
This could explain why it seems that function in pipe is executed before getLastImportTime()
So try to change your function like so
var getLastImportTime = function () {
...
database.open();
database.query("SELECT ...");
return buildPromise.promise();
}; | unknown | |
d1597 | train | just update your vue-loader. in recent weeks, it updates fast! from v16 back to v15. | unknown | |
d1598 | train | You can do it this way, but it might require several complex string expressions.
E.g. create a ForEach loop over .xls files, inside the loop add an empty script task, then a data flow to load this file. Connect them with a precedence constraint and make it conditional: precedence constraint expression will the check if file name does not end with -loaded.xls. You may either do it in script task or purely using SSIS expression on precedence constraint. Finally, add File System Task to rename the file. You may need to build new file name with another expression.
It might be easier to create two folders: Incoming for new unprocessed files, and Loaded for the files you've processed, and just move the .xls to this folder after processing without renaming. This will avoid the first conditional expression (and dummy script task), and simplify the configuration of File System task.
A: You can get the SQL File watcher Task and add it to your SSIS. I think this is a cleaner way to do what you want.
SQL File Watcher | unknown | |
d1599 | train | On second thought, let me expand on my comment:
You can't set Dockerfile environment variables to the result of commands in a RUN statement. Variables set in a RUN statement are ephemeral; they exist only while the RUN statement is active
If you don't have access to the host environment (to pass arguments to the docker build command), you're not going to be able to do exactly what you want.
However, you can add an ENTRYPOINT script to your container that will set up dynamic environment variables before the main process runs. That is, if you have in your Dockerfile:
ENTRYPOINT ["/docker-entrypoint.sh"]
And in /docker-entrypoint.sh you have:
#!/bin/bash
branch=$(git branch | sed -n -e 's/^\* \(.*\)/\1/p' | awk -Frelease/ '/release/{print $2}') \
&& if [[ "$branch" != qa* ]]; then branch=$(git log -1 --pretty | grep release\/ | awk -Frelease/ '/release/{print $2}' | awk -F: '{print $1}'); fi)
export EXPORT_ENV="$branch"
exec "$@"
Then the EXPORT_ENV environment variable would be available in the environment of your CMD process. | unknown | |
d1600 | train | I'm the pathos author. When I try your code, I don't get an error. However, if you are seeing a CPickle.PicklingError, I'm guessing you have an issue with your install of multiprocess. You are on windows, so do you have a C compiler? You need one for multiprocess to get a full install of multiprocess. | unknown |
