This will usually be a dead end, and you're better off just blocking the users attempting the attacks, as most machines performing attacks are not usually owned by the 'hacker', and instead they could be compromised machines, or someone abusing a website which offers free vulnerability scans or something similar. | Most ISPs have an abuse@ispname.com email address for reporting such things..

Source: Linux man [strtok\_r](http://man7.org/linux/man-pages/man3/strtok_r.3.html) | Your function `getmask()` invokes undefined behavior:
* you copy the string argument into a local array `x`;
* you parse that with `strtok()` which returns a pointer into the same local array `x`.
* you return this pointer `mask` to the caller. This pointer becomes invalid as soon as you exit this function.
You should instead return a pointer to an allocated copy of this array so it remains valid after you return to the caller.
Futhermore, you should indeed avoid using `strtok()` because it is not reentrant: as you noticed, you cannot implement nested parsers with this function.
Other functions are available for parsing strings:
* `strchr()` locates a character in a string ;
* `strstr()` locates a substring in a string ;
* `strspn()` matches a set of characters at the beginning of a string ;
* `strcspn()` matches the complement of a set of characters at the beginning of a string ;
* you can also parse the string by hand, testing characters in a loop.
Here is an example:
```
#include <stdlib.h>
#include <string.h>
char *getmask(const char *s) {
/* allocate a copy of the mask part
* the mask starts after the first '/'
* and stops at the first space or another '/'
*/
len - 0;
s = strchr(s, '/');
if (s != NULL) {
s++;
len = strcspn(s, "/ \t\r\n");
}
/* allocate space for the mask string */
char *mask = malloc(len + 1);
if (mask != NULL) {
/* copy the mask string */
memcpy(mask, s, len);
mask[len] = '\0';
}
return mask;
}
```
The function is cumbersome but very precise. It behaves almost the same as what you intended with `strtok()`, the only difference is the handling of multiple consecutive `/` bytes which `strtok()` would skip and `strchr()` does not.
Here is an alternative with `sscanf()`:
```
#include <stdlib.h>
#include <string.h>
char *getmask(const char *s) {
char mask[256];
/* skip characters different from /, then skip slashes, then
* copy characters until another / or whitespace
*/
if (sscanf(s, "%*[^/]%*[/]%255[^/ \t\n]", mask) != 1) {
*mask = '\0';
}
return strdup(mask); /* POSIX function to allocate a copy of a string */
}
```
It is much simpler, but fails if the string starts with `/`.
`strdup()` is a very useful function to allocate a copy of a string. It is available on POSIX compliant systems. It you do not have it, it can be easily implemented as:
```
#include <stdlib.h>
#include <string.h>
char *strdup(const char *s) {
char *p = malloc(strlen(s));
if (p != NULL) {
strcpy(p, s);
}
return p;
}
```
Strings allocated by `getmask()` should be freed by `free()` when no longer needed.
You can use similar methods to parse your input string into ip/mask address pairs before calling `getmask()`.
You could also provide a destination buffer to `getmask()` to avoid the complexities of memory management:
```
char *getmask(char *dest, size_t size, const char *s) {
if (dest != NULL && size > 0) {
char mask[256];
/* skip characters different from /, then skip slashes, then
* copy characters until another / or whitespace
* dest cannot be used directly because size cannot be passed
* sscanf easily
*/
*dest = '\0';
if (sscanf(s, "%*[^/]%*[/]%255[^/ \t\n]", mask) != 1) {
strncat(dest, mask, size - 1);
}
}
return dest;
}
```
Parsing is tricky because you must be careful to handle all cases. The specifications are usually not precise enough so implementors must make choices for special cases. The tools provided by the C library for parsing are old and clunky, especially `strtok()`, `sscanf()`. Be careful when using these, even experienced programmers get bitten by their side effects and shortcomings. |

Source: Linux man [strtok\_r](http://man7.org/linux/man-pages/man3/strtok_r.3.html) | `strtok()` cannot be used on comma separated strings if there are null values there e.g. "one,two,,four,five,,,eight".
Using `strtok(token,",")` will return "one", "two","four"... where you might have thought an null string "" would be returned after"two". This caught me out when trying to parse the output from a GPS receiver.
Instead use `strsep()` which is thread safe like `strtok_r()` but will return zero-length strings i.e. "one","two","","four"... in the example earlier.
`strsep()` might not be in some runtime libraries, but you can find implementations by searching online. |

] | Push notifications don't work out of the box and this is not documented on the React Native docs. There are a few things you need to add to your project first in order to wire up notifications. I found this information from an open issue on github <https://github.com/facebook/react-native/pull/1979#issue-94795697>.
You basically need to wire the notifications manually in AppDelegate.m and call the corresponding methods from the RCTPushNotificationManager so the PushNotificationsIOS class can handle them from your javascript code.
1. add RCTPushNotification to your project (and also link binaries in build settings).
2. add this header to Header Search Paths: `$(SRCROOT)/node_modules/react-native/Libraries/**`
3. add this code to AppDelegate.m:
---
```
#import "RCTPushNotificationManager.h"
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{
[RCTPushNotificationManager application:application didFailToRegisterForRemoteNotificationsWithError:error];
}
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
[RCTPushNotificationManager application:application didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)notification
{
[RCTPushNotificationManager application:application didReceiveRemoteNotification:notification];
}

12,423,716 | I'm working on a drawing application which requires high levels of accuracy, and I'm wondering which of the major browser platforms (including the HTML Canvas element, and Flash) give the best sub-pixel layout accuracy, both for drawn elements (rectangles in the Canvas or Flash, absolutely positioned DIVs in the browser), and for text.
There are a number of posts related to this, both on this site and others, (see list at bottom), but many are quite old, and none summarises the current situation.
My understanding is that Flash has native support for sub-pixel positioning, using twips to position objects to one twentieth of a pixel, and that when the TextLayoutFramework is used, this accuracy also extends to text. There is at least one report, however, that this doesn't work properly in Chrome. Can anyone confirm this?
My understanding of the situation in the browsers is that Firefox 14+ supports sub-pixel positioning for text and drawn elements, both in page layout and within the Canvas, but I haven't been able to ascertain how accurate this is.
I understand Chrome (as of v21) does not support sub-pixel positioning at all.
I understand IE9 doesn't support sub-pixel positioning, but it appears from the MS blog post linked below that IE10 will.
I don't know if there's any Mac/PC variance in this, and I don't know also if the accuracy of Flash varies between platforms and/or browsers.
I understand a summary question like this may provoke some debate, but I believe this is specific enough for people to provide useful answers, and hope that this thread can be a reference for the state of positioning accuracy up to now.

] | Currently, you can expect the best rounding and sub-pixel support to come from Mozilla with IE as the runner up. IE might end up being more fine tuned, but their release cycles are so long that Mozilla is likely to stay ahead of them.
As far as doing sub-pixel layout, you may be chasing a wisp, because the sub-pixel advantage improves anti-aliasing issues, not screen location accuracy. Your image will never be more accurate than 1 pixel from the true position, regardless of sub-pixel support.
The reason why some browsers don't zoom properly has nothing to do with sub-pixel support, it is because they are not remembering the exact position and rounding correctly. In other words, they are prematurely rounding the position and that causes the image to be mis-aligned. | **Short answer:**
No. It is NOT possible/documented.
And even if determined experimentally, it is NOT guaranteed to remain the same in future.
**Long answer:**
At sub-pixel accuracies, there is a lot of variance among Browsers/OS/HW about how the input is captured/rendered. With h/w acceleration being enabled on most modern browsers, there are a large number variations in rendering across different PCs running different browsers on different operating systems. So much so that, it is possible to even identify every unique user by the slightly different [**variations in the rendered output of a common sample**](http://cseweb.ucsd.edu/~hovav/dist/canvas.pdf).
Rather than worrying about the discrepancies in the underlying frameworks, How about designing the UI of your drawing application to be independent of those problems. Couple of methods i can think of right now are:
1. Allow editing the image at zoomed/magnified levels.
2. Design a snap-to-grid method for elements.
**Update:**
The "zoom" operation would your custom implementation and NOT a feature of the underlying frameworks. So if you need sub-pixel accuracy to the order of 1/10th of a pixel, one would need to have a 10x\_zoom() implemented as part of you web-app which would render the data from
1st pixel --> 10x10pixels at (0,0),
2nd pixel --> 10x10pixels starting from (11,11).
This way one would have a very magnified view of the data, but the framework is blissfully unaware of all this and renders accurate to the onscreen-pixel(which in our case now is 1/10th of the image pixel).
Also an important thing to note that this operation would consume a lot of memory if done for the entire image at once. Hence doing this for ONLY the visible part of the image in a "zoom-window" would be faster and a less memory intensive process.
Once implemented in your drawing web-app the sub-pixel inaccuracies in the frameworks might not turn out to be a problem for the user as he can always switch into these modes and provide accurate input. |

] | Your initial problem is, that you attempt to access the classes internal variables via the `TransitionSystem` interface - you will of course have only access to the methods (and possibly constants) defined in your interface. This is really a good thing, as it separates the public contract (the interface) from the implementing class! And thus you should rethink your unit tests to use only the interface methods as well! The interface (along with wanted behaviour defined in some requirements document) defines the contract of the implementing class to the outer world, and anything you cannot test by its interface is just that: internal implementation detail of the implementing class). | Because the compiler thinks the variable ts has the type "TransitionSystem".
You can change the code to:
```

57,849,569 | I have a React component named "Badge" returning some Text that is styled bold.
```
render() {
return (
<div>
<Text weight={'bold'}>
{this.props.label}
</Text>
</div>
)
```
Now, I use "Badge" in another component named "Card".
Because in Badge component all Text is styled bold, the whole sentence is bold as well:
```
return (
<div>
<Badge lable={'This part of the sentence is ' + 'normal font style' + ' and the rest is bold.'}></Badge>
</div>
)
```
Now, I would like to style the items in this element differently: I want to remove the bold style from 'normal font style' - only for this single part of the string. I already tried this way, but it doesn't work:
```
<Badge label={'This part of the sentence is ' + <span class=”normalText”>'normal font style'</span> + ' and the rest is bold.'}></Badge>

Hope this will work for you! | The more appropriate system is take label value as badge's children. to declare Badge component code like this example:
```
const Badge = props => {
return (
<div className={`badge-class`}>
<Text weight={'bold'}>

</Text>
</div>
)
}

return (
<div>
<Badge>
This part of the sentence is <span className={`normal-texts`}>normal font style</span> and the rest is bold.

24,170,402 | We have run into a strange bug that we're having problems debugging.
We have a MDI workspace that uses Microsoft CAB, DevExpress components, and .Net 3.5.
If users open two windows in the workspace that each contain a `UserControl` bound to two separate data models, then minimize both of them, the first window to minimize is getting it's bound fields cleared when the second one minimizes.
The `.Equals` and `.GetHashCode` methods of the data model have been overridden so that both data models are considered equal. If we change that so they are unique, we do not get this behavior.
Here's some example pseudocode showing the problem
```
var a = new MyWindow();
a.DataModel = new SomeClass(123);
a.ShowInMdiWorkspace();
var b = new MyWindow();
b.DataModel = new SomeClass(123);
b.ShowInMdiWorksace();
a.Minimize();
// If SomeClass.GetHashCode() is overwritten to consider two objects
// as equal based on the value passed in, then the data bindings for A
// get cleared on this call. If SomeClass.GetHashCode is unique, then
// this problem does not happen.
b.Minimize();
```
Here's the Call Stack when the second window gets minimized:
At the `EndEditSession()` call in the stack trace above, it is calling `EndEditSession` for the *second* window minimized, while by the time the Stack Trace gets past the `[External Code]` to the OnChange breakpoint I have set, it is firing the change method in the *first* window.
`EndEditSession()` is something custom we have implemented which looks something like this
```
protected void EndEditSession()
{
IBindingValue bv = null;
if (_bindingValues == null)
return;
if (_data != null)
{
foreach (KeyValuePair<string, IBindingValue> kvp in _bindingValues)
{
bv = kvp.Value;
if (bv.IsBindable)
((PropertyManager)bv.Component.BindingContext[_data]).EndCurrentEdit();
}
}
}
```
`_bindingValues` gets populated when the UserControl initializes its data bindings. The key fields are the name of the bound control, and the value fields are a custom object which stores the control itself, its name, its bound value, and default value. `bv.Component` returns the control that the binding is set on, which in the case of my testing is a customized DevExpress `LookupEdit`
`_data` contains the data model for the `UserControl`, and I can verify that it is set to the instance for the second window.
My original thought was that the `BindingContext` was shared so the wrong `PropertyManager` was being returned, however I have verified that the `.BindingContext` for the two forms and controls are separate.
Is it possible that having two separate copies of a `UserControl` bound to two separate instances of a data model would get its bindings mixed up when the `GetHashCode` method has been overridden so that the two objects are considered equal?
I am not very familiar with the inner workings of the WinForms binding system, or with exactly how CAB's MDI workspace gets managed.
My theory is that when the first window minimizes, it is unloading the controls to save on memory, then when the second window minimizes the internal hash table that manages the bindings is incorrectly getting confused and running an update to take data from the first minimized window (which is now blank) and updating its datasource. There are plenty of holes in this theory, however its the only thing I can think of. | 2014/06/11 | [

] | I don't know the internal workings the WinForm widget, but it seems that since you've encountered an issue with **overriding** equals that you'd be better off **working around**.
**If you need to evaluate equality for your own purposes:**
An approach is to provide your own method to evaluate equality, rather than changing the default behavior.
**If your intention is to change how the widget treats the objects:**
An approach is to make a static object factory for your class. The factory could maintain a collection of all of the objects created using weak references. Weak references allow the GC to collect the objects. The factory can then check the collection of previously created objects. If a match is found then return the existing one. If not then create it. This way rather than having two different objects that evaluate two equal (override equals) you'd have a single object with two references that is equal (same memory).
Hopefully one of these other approaches will solve your problem. | `BindingContext` object are not sharing its fields and properties with any other `BindingContext` because its fields and properties are not static.
But, it is possible to have one `BindingContext` object for several controls.
In the first case if several controls have the same parent and have not their own `BindingContext` then `BindingContext` property of this controls will return `Control.Parent(.Parent...).BindingContext` object.
In the second case there are can be something like this:
```
var bindingContext = new BindingContext();
var a = new SomeControl();
var b = new SomeControl();
a.BindingContext = bindingContext;
b.BindingContext = bindingContext;
```
In the third case `BindingContext` can be overwritten in such a way.
I don't know what is going on in your case, so I can only recommend to do something like this before initializing data bindings:
```
var a = new SomeControl();
var b = new SomeControl();
a.BindingContext = new BindingContext();
b.BindingContext = new BindingContext();
```
If this does not solve your problem then you need to check the populating of your `_bindingValues` object. It is possible that during the populating of this object it is populated with wrong values. |

I have written a program that will return the sum of the multiples of *any* list of positive integers. So for example if I wanted to know the sum of every integer that was a multiple of 3 and 5 that is less than 10 I would add 3,5,6, and 9 to get 23.

raise ZeroDivisionError('Cannot start with the number 0')

] | ### Simpler implementation
You don't need `naturals` at all, and `offset` either.
You could make the outer loop iterate over the `range(start, end)`,
and for each value check if it can be divided by any one of `nums`,
and add to the sum.
```
msum = 0
for i in range(start, end):
for num in nums:
if i % num == 0:
msum += i
break
return msum
```
### API
The interface of your function is not intuitive:
* The range start parameter goes after the range end parameter. That's not intuitive. Consider how Python's `range` works:
+ With one arg, the first arg is the end of the range
+ With two args, the first arg is the start, the second is the end of the range. It's natural that wayI suggest to follow that example
* The first arg is called "multiple", singular. It's not a multiple. It's a collection of numbers. So `nums` would be a better name, and it would make it easier for readers to understand how to use this function
### Input validation

The zero division error is inappropriate. You did not divide by zero,
and it won't make sense for callers to catch this exception and handle it.
In other languages this should be an `IllegalArgumentException`, in Python `ValueError` would be more appropriate.
The real problem is not division by zero, but inappropriate use of the function.
But then, why is `start=0` inappropriate? I see nothing wrong with that.
What would be wrong is having 0 in `nums`.
That's what you should validate instead.
### Coding style
The recommended practice is to use `snake_case` for function names, not `CamelCase`. See more coding style recommendations in [PEP8](http://www.python.org/dev/peps/pep-0008/). | One big problem I see with your code is that you're using `range` to construct a data structure with the entire range of possible numbers in it. This could lead to huge memory requirements if `start` is far from `end`. A better choice would be to put the multiples you've already used into a `dict` ([dictionary](https://docs.python.org/2/tutorial/datastructures.html#dictionaries)).
It's also suboptimal to check every single natural number between `start` and `end` for divisibility. `for ... in ...` is a useful tool, but it's not always applicable. This is one instance where using a counter would be preferable, since you could just add `num` to the counter each time and not have to check (you'd of course have to do the modulo once in order to get the right starting point). |

I have written a program that will return the sum of the multiples of *any* list of positive integers. So for example if I wanted to know the sum of every integer that was a multiple of 3 and 5 that is less than 10 I would add 3,5,6, and 9 to get 23.
My function can do this for any number of positive integers, between any range that starts from 1.
```
# Function to return sum of multiples that are within a certain range
def MultiplesSum(multiple, end, start=1):
mSum = 0
naturals = range(start, end)
offset = -start
if start == 0:
raise ZeroDivisionError('Cannot start with the number 0')
for num in multiple:
for i in naturals:
if i % num == 0 and naturals[i+offset] != 0:
# print mSum,"+", i,"=",i+mSum
mSum += i
naturals[i+offset] = 0
i += 1
return mSum
problem1 = MultiplesSum([3,5,2], 16)
print problem1
# prints 88

] | If there are \$m\$ numbers in `multiple` and \$n\$ numbers in the range from `start` to `end`, then the function in the original post takes \$O(mn)\$. There's an alternative algorithm, using the [inclusion–exclusion principle](http://en.wikipedia.org/wiki/Inclusion%E2%80%93exclusion_principle), that takes \$O(m2^m)\$, which is faster when \$2^m < n\$.
```
from fractions import gcd
from functools import reduce
from itertools import combinations
def lcm(seq):
"""Return the lowest common multiple of the numbers in the sequence."""
return reduce(lambda a, b: a * b // gcd(a, b), seq)
def sum_multiples(numbers, start, stop):
"""Return the sum of all values between start (inclusive) and stop
(exclusive) that are multiples of any values in the sequence numbers.
"""
result, sign = 0, 1
for i in range(1, len(numbers) + 1):
for c in combinations(numbers, i):
m = lcm(c)
a = (start + m - 1) // m
n = (stop + m - 1) // m - a
result += sign * (a * n + (n - 1) * n // 2) * m
sign = -sign
return result
``` | I would suggest a simpler solution because Python is 'battery-included':
```
def multiple_sum(start, end, step):
return sum(range(start + (start % step), end, step))

hibernate 4.1.7 should work fine. Yes you can use an XML configuration rather than annotations, I've used both in Spring an Tomcat an it works fine.

Let me know if this helps you. | As far as I understand, if you say you want "to get is to close each browser after each test is finished", you need to use @AfterMethod and @BeforeMethod. This would ensure that after every @Test runs, the browser gets closed.
With @AfterTest, this would happen just once - note Test in @AfterTest maps to `<test>` in the testng xml and does not map to @Test in your code.
@AfterSuite would just close your browser once in the entire execution, which would mean if you wanted a clean session on each @Test, that won't happen.
If you do not want a clean session, then @Before/@AfterSuite would work as well. |
47,090 | Consider a rectangular cross sectional beam for instance with dimensions a = 1 mm and b = 1 mm, fixed at one end and transverse force at the other. I will get the maximum stress at the farthest away point from the neutral axis. Now, if I decrease the dimensions to a = 0.5 mm and b = 0.5 mm, then we know that the maximum stress at the farthest away point from neutral axis will increase.
But my question is does this increase in stress happens because the tensile force (or the compressive force) at the farthest away point has increased, or is it solely due to the fact that I have decreased the cross sectional area of the beam? | 2021/09/10 | [
"https://engineering.stackexchange.com/questions/47090",
"https://engineering.stackexchange.com",
"https://engineering.stackexchange.com/users/30547/"
] | It is actually more complicated than that.
* the magnitude of the stress increases 8 fold
* the tensile forces increase so that they generate the counteracting bending moment.
---
When you decrease the cross-section from 1mm x 1mm to 0.5mm x 0.5m, the cross-sectional area decreases to 1/4 of the original but
* the second moment of area decreases by $ \left(\frac{1}{2}\right)^4= \frac{1}{16} $(i.e. $I\_{new} = \frac{I\_0}{16}$ and
* the section modulus decreases by $\frac{1}{8}$ (ie. $W\_{new} = \frac{W\_0}{8}$)
The maximum stress due to bending is given from:
$$\sigma\_b = \frac{M}{W}$$
So the ratio of the original (0) and the (new) will be
$$\frac{\sigma\_{b,new}}{\sigma\_{b,0}} = \frac{\frac{M}{W\_{new}}}{\frac{M}{W\_{0}}}$$
$$\frac{\sigma\_{b,new}}{\sigma\_{b,0}} = \frac{W\_{0}}{W\_{new}}=8$$
So by reducing by half both dimensions, the stresses due bending increase 8 fold.
---
why do the tensile forces increase
----------------------------------
The tensile (and compressive) forces during bending increase so that their combined effect generates the required bending moment to counteract the bending moment from the external loads.
[](https://i.stack.imgur.com/hXVYs.png)
**Figure (source [a builders engineer](http://www.abuildersengineer.com/2014/06/beams-section-modulus.html)**
The above illustration shows in (1) a section with a bending moment M is presented. Notice that the resulting normal forces are such that they counteract M.
The idea is that:
* the displacement changes linearly with the distance from the neutral center.
* A force at a distance from the neutral axis ($F\_i$) develops that is proportional to the displacement
* Each force ($F\_i$) produces a moment $M\_i$
* The integral of all the moment over the cross-section should be equal to M
$$M= \sum M\_i$$
Figures 2 and 3 show what happens to the tensile forces when the cross-section is reoriented. | Section properties in a fluxural member play a dual role as opposed to members in simple tension or compression.
in a tension member stress increases jist because there are less fibers to share the load.
But in a beam's reduction in section has dual effect of rediucing the second area moment which weakens the beam's bending resistance and also the fact that now there is less fibers to share the load.
reducing the height by half reduces the I, 2nd area moment by 1/4 and reducing the width by half reduces the the srea by half. so 8 times load on th ultimate fiber. |
50,626,223 | i am fairly new to React and this is my first project with Redux.
I get some data and set it in the state-tree. When my reducer `ADD_PRODUCTS_TO_CART` runs, my `Products->render()` runs, but `Product->render()` does not, despite having a key.
Here is a gist, it was the most basic i could boil it down to. Hope it makes sense, i've included a file that represents the state of the tree, so you can see the data structure.
<https://gist.github.com/hoodweb/e4005e4f1fc95682d4dd9bf87b81fe39>
**TLDR:** Basically the stock decrements in the statetree, but is not rendered. What am i doing wrong?
**Update:** I have put in `console.log()` in all render methods, to see what is called. When i decrease the stock of my product, the product is not called. This is most likely due to the `.map(() => <Product/>)` i am doing. I tried changing my `key={}` property to include the stock like this:
`.map((obj) => <Product key={obj.ID.toString() + obj.Stock.toString()} data={obj} />)`
Which seems to work. But I do know how stable this is.
**Update2:** It seems that if i take my `data={}` property at put it into seperate properties like this
`<Product key={obj.ID} stock={obj.Stock} title={obj.Title} price={obj.Price} beforePrice={obj.BeforePrice}`
it works. So that is my solution for now. | 2018/05/31 | [

] | In `render` function of `Product` you got:
```
if (data.Variations) { //TODO: Variation logic
return false;
}
```
Because in `data` you got `Variations` param, it goes through this scope (beacause `Variations` is not `null` or `undefined`) and returns null instead of rendering component.
remove `return false` and your code should work fine. | Like @kiarashws said, whenever you `return false` in your `render()` method, it doesn't render. Make sure to not render only when you don't want to.
Is commonly see code like this:

if (props.shouldNotRender)
return null or false;
return <div>
...
</div>

42,254,095 | I have 2 entities in which totally 12 properties are there of 3 variations of min, max and average of some particular type of fields. Hence I refactored the 2 entities into 3 entities making the 3rd entity as 'Values' which contains 3 properties i.e min, max and average. And reduced the 12 properties into 4 relationships. Here's a replica of my models as an example in the image below.

As you can see I have one-to-one unidirectional relationship with the 3rd entity. However Xcode keeps on complaining about 'Inverse' relationship.

As per me I can add 4 relationships in 'Values' and update all to become 'inverse', however this doesn't seem to be the right solution as when the second entity gets tied to the 'Values', it will have additional 3 nil relationships and whereas in case of first it will have 1 additional nil relationship. Both of these are unnecessary.
Refactoring 'Values' and splitting it into two similar entities also is not a good solution either I believe.

Also, if you want to make things easier, you should look into (if possible) avoid 3 objects and have a single object, or two objects, with the [propertiesToFetch](https://developer.apple.com/reference/coredata/nsfetchrequest/1506851-propertiestofetch) of the `NSFetchRequest` in mind.

9,950,449 | I have an issue where I'm using the Nivo jQuery slider on a HTTPS: site and its javascript seems to be throwing a mixed content error in IE 8.
I currently have a forum post up in the Dev7 Studios forum with no response yet. And I've googled for a couple of days on the IE 8 mixed content error.
So far, I haven't found a clear fix except for one post where a guy stated that sometimes the "innerHTML" in a jquery file can cause the error. But he didn't really list a clear fix.
Does anyone have any insight in to this? Any help or direction appreciated. | 2012/03/30 | [

Normal browsers don't have a problem with URLs for dynamic content that aren't fully qualified, protocol and all. But IE8 *sometimes* drops the ball and instead of putting in the protocol and host, it puts in "about:" in front of your path, and fails to trust that in a https context.
I edited nivoslider to qualify the URLs of all the images it draws dynamically. Further development would be needed to allow use of query strings in image URLs.
Here's my [edited source](http://pastebin.com/znhGMhjh). | I was having same issue. In the header section I changed the src from `http://"mysite"/jquery.nivo.slider.pack.js` to just `/jquery.nivo.slider.pack.js` and worked. |
37,132,999 | I want sql query for update a record. For example there are 3 columns in my table -
Name , Address, Email
and when I update any one column other columns value should be null without set null to them. Like
```
Update tbl_Student set Name = 'XYZ' where id = 1
```
In above case only Name column should update and other column should update by null.
FYI,
As there are two many columns that I need to set null that's why I wanted some kind of query to do that. Like -
```
ID ADDRESS NAME EMAIL
1 PARK ROAD JOHN john@gmail.com
```
And I want to update only name and want rest of the fields should be null.Like
```
Update Table SET NAME = 'NICK' WHERE ID = 1

```
ID ADDRESS NAME EMAIL
1 NULL NICK NULL

See the documentation about $evalAsync at: <https://docs.angularjs.org/api/ng/type/$rootScope.Scope#$evalAsync> | basically the listeners is not ready and myEvent broadcast already so first you should emit the event to controller "FirstController" and then broadcast to the "SecondController" then it will work.
Here is the fiddle
```
var myApp = angular.module('myApp',[]);
myApp.controller('FirstController', function ($scope, $rootScope) {
$scope.myInput = 'Initial data';
$scope.broadcast = function() {
console.log ('broadcasting: ' + $scope.myInput);

57,660,213 | I need to do something quit simple - I would like to do a one time http request to a static data - I would like to do it either when the application starts or as "lazy-loading", when needed. I would like to send the http request one time and set a variable (member -> property) with the returning results, so I can use that property later on instead of doing another http request.
Below is my code - is it the best practice solution ?
Any remark\improvement\another way of doing it - would be appreciated.
The "lut" is for "lookup table" dat -> the static data.
```js
@Injectable({providedIn: 'root'})
export class lutData
{
_someData : somedataType[] = null;
constructor(private lutService : LutService){} //The service is a simple http service
public get SomeData() : somedataType[] {
if (this._someData){
return this._someData;
}
else {
this.lutService.getSomeLutData().subscribe(result =>{
this._someData = result;
return this._someData;
});
}
}
}
```
This is the component that should use the data: I'm using injection, but maybe there's a better way doing it.
```js
export class XXX_Component {
someData : somedataType[];
constructor(private lookUpData : lutData) { }
ngOnInit() {
this.setLutData();
}
setLutData() {
this.someData = this.lookUpData.SomeData;
}

public someData() : Observable<somedataType[]> {

return of(this._someData);
}
else {
const req = this.lutService.getSomeLutData();
req.subscribe(data=> this._someData = data);
return req;
}
}
}
```
**Component**
```js
export class XXX_Component {
someData$ : Observable<somedataType[]> = this.lookUpData.someData();
constructor(private lookUpData : LutData) { }
}
```
Then in your component template use the async pipe:
```html
<div *ngFor="let item of (someData$ | async)">
{{item}}
</div>
``` | Store data in a service is very good way of making data available for all the components and also maintain the consistency. But calling the http request whenever your project is start or app is render on the device, depend on the use case.
It's good, If you need updated data at least once whenever user land on your page like, user\_details, user jwt keys etc.
Consider an example, suppose you have a page where you listing pricing/packages details of your services. And these information are not changing very frequently. For this example calling http service at the time of start your project is unnecessary.
For this type of application, where your data are not changing very frequently you can call http once and after that store the response in your native storage with some validation roles. So whenever your page is open
1. Look into native storage for the data.
2. If found and pass the validation role.
3. Then store in a service for future use.
4. If not found or not able to pass validation role.
5. Call http request again.
6. Save the response to native storage with same validation role.
7. And also set the response in your service for future use. |

A ListBoxFor requires 2 properties on your view model:
1. A collection property of a primitive type (`string[]`, `id[]`, `Guid[]`, ...) that will hold the ids of the selected elements
2. An `IEnumerable<SelectListItem>` property that will hold the list of all items
and then in the view:
```
@Html.ListBoxFor(x => x.SelectedPriceIds, Model.Prices)

Now your controller actions will pass this view model to the view instead of your domain objects which simply are not adapted to what you are trying to achieve. It is inside the controller actions that you will populate this view model from your domain models. | i can select multiple value in your listbox so i will suggest to do this in another type

\begin{eqnarray\*}
z^{2k}=(nz)^{2k} \Rightarrow (n^{2k}-1)z^2 = 0 \Rightarrow (n^k+1)z(n^k-1)z=0

Step 2. Before the entry `E` is synced, `U` decides to modify it. An activity `A` starts for modifying the column values of `E`.
Step 3. While the user is modifying the entry, the SyncAdapter starts and sends the entries with `status == TO_SYNC` to the server. For each entry, the `SyncAdapter` sets `status = SYNCED` once it receives a positive answer from the server.
Step 4. Let's say that a concurrent access to the same entry `E` causes a conflict:
1. The SyncAdapter reads `E`, sends `E` to the server
2. The activity `A` completes and sets `E` status to `TO_SYNC`
3. The SyncAdapter receives the ok from the server and sets the `status` of `E` to `SYNCED`
4. At this point the new values of `E` will not be synced since the value `TO_SYNC` has been overwritten by the SyncAdapter.
My question is: how can I avoid such issue without blocking the entire database with a `begin/end transaction` while syncing (which could take a long time to complete)? Should I fall back on a classical java lock on single entries? Is there a more elegant way? | 2015/02/03 | [

66,044,532 | Amazon ECS supports two different types of health checks:
* [Target Group health checks](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/service-load-balancing.html) make a configurable network request
* [Container health checks](https://aws.amazon.com/about-aws/whats-new/2018/03/amazon-ecs-supports-container-health-checks-and-task-health-mana/) run in the docker container and can be configured to run any shell command that the container supports
If both health checks are configured, which one wins? If *either* fails is the Service marked as `UNHEALTHY`? Or *both*? Can I configure one to override the other?
I'd very much like the Target Group health status to not cause ECS to continually bounce the service and I was hoping the container Health Check could be used to override it. | 2021/02/04 | [
"https://Stackoverflow.com/questions/66044532",
"https://Stackoverflow.com",
"https://Stackoverflow.com/users/2824722/"
] | The AWS documentation is somewhat vague on this topic, but does suggest a high degree of coupling between ALB & ECS when it comes to health checks. i.e. see the [documentation](https://docs.aws.amazon.com/elasticloadbalancing/latest/application/target-group-health-checks.html) for `healthCheckGracePeriodSeconds` and `minimumHealthyPercent` for examples of ECS health check behaviour which is influenced by the presence or absence of a load balancer.
The `healthCheckGracePeriodSeconds` may be useful to avoid a failed ALB health check from causing the ECS container to be restarted (during service startup at least):
>
> The period of time, in seconds, that the Amazon ECS service scheduler should ignore unhealthy Elastic Load Balancing target health checks, container health checks, and Route 53 health checks after a task enters a RUNNING state. This is only valid if your service is configured to use a load balancer. If your service has a load balancer defined and you do not specify a health check grace period value, the default value of 0 is used.
>
>
> If your service's tasks take a while to start and respond to health checks, you can specify a health check grace period of up to 2,147,483,647 seconds during which the ECS service scheduler ignores the health check status. This grace period can prevent the ECS service scheduler from marking tasks as unhealthy and stopping them before they have time to come up.
>
>
> | In my experience, either one will cause your container to be decommissioned. I would say you probably don't need the container health check if you have a target group performing the check. |

```
def example(somefunc):
somefunc()

example(lambda x: x ** 2)
```
Returning one is a little trickier, but not much.
You can return a lambda:
```
def example2():
return lambda x: x + 1
```
Or you can build an inner function, and return that
```
def example3():
def rf(x):
return x + 2
return rf
myfunc = example3()
myfunc(2) #returns 4
``` | math.sqrt(x) is NOT a (Python) function, math.sqrt is a function. Notice the missing (x). In the same vein, 1/(2 \* math.sqrt(x)) is not a function but (lambda x: 1/(2 \* math.sqrt(x))) is a function.
The issue is that
```
a = lambda x: x
```
and
```
b = lambda x: x
```
will yield two different python functions that are equivalent from a mathmatical point of view. So it is not that helpful to test functions for equality. You would need to actually "parse" them in order to find mathmatical derivatives.
Parsing the inner definitions is possible but not even close to simple. |

hope it helps | Signing for release: $1.apk -> $1\_release.apk"
GeneralMills&GoogleApps#2012
Step 1: Removing any previous signing
Change the extension of your .apk to .zip
Open and delete the folder META-INF
Change the extension to .apk
Or
Command:
• zip [originalapk]
Example:
• zip "$1".apk -d
Step 2: Signing with release.keystore..
Command:
• jarsigner –verbose –keystore [keystorefile] –signedjar [unalignedapk] [originalapk] alias\_name
Example:
• C:\Program Files\Java\jdk1.6.0\_43\bin> jarsigner -verbose -keystore release.keystore -signedjar "$1"\_unaligned.apk "$1".apk release
Step 3: Aligning
Command:
• zipalign -f 4 [unalignedapk] [releaseapk]
Example:
• C:\Users\G535940\Downloads\adt-bundle-windows-x86\adt-bundle-windows-x86\sdk\too
ls>zipalign -f 4 "$1"\_unaligned.apk "$1"\_release.apk
Step 4: Cleaning up
Command:
• rm 4 [unalignedapk]
Example:
• rm "$1"\_unaligned.apk
Additional Commands might help:
1. To generate new key with keytool
keytool -genkey -alias -keystore
2. To list keys
keytool -list -keystore
Command to generate a keyhash for the Facebook features
Command:
• keytool -exportcert -alias alias\_name -keystore [keystorefile] | openssl sha1 -binary | openssl base64
Example:
• C:\Program Files\Java\jdk1.6.0\_43\bin>keytool -exportcert -alias release -keyst
ore release.keystore |opens l sha1 -binary | openssl base64
Note:
To sign our apks we have downgraded JDK from 1.7 to 1.6.0\_43 update.
Reason:
As of JDK 7, the default signing algorithim has changed, requiring you to specify the signature and digest algorithims (-sigalg and -digestalg) when you sign an APK.
Command:

hope it helps | Assuming your keys are stored in `keys.keystore`, you can run:
```
$ keytool -list -keystore keys.keystore
Your keystore contains 1 entry
your_key_alias, Jan 3, 2013, PrivateKeyEntry,
Certificate fingerprint (SHA1): 8C:C3:6A:DC:7E:B6:12:F1:4C:D5:EE:F1:AE:17:FB:90:89:73:50:53
```
to determine the alias of your key. Then run:
```
zip -d your_app.apk "META-INF/*"
jarsigner -verbose -keystore keys.keystore \
-sigalg MD5withRSA -digestalg SHA1 -sigfile CERT \
your_app.apk your_key_alias
```
to re-sign `your_app.apk` with the key named `your_key_alias`.
The extra `-sigfile CERT` option seems to be necessary as of JDK 8. |

] | Signing for release: $1.apk -> $1\_release.apk"
GeneralMills&GoogleApps#2012
Step 1: Removing any previous signing
Change the extension of your .apk to .zip
Open and delete the folder META-INF
Change the extension to .apk
Or
Command:
• zip [originalapk]
Example:
• zip "$1".apk -d
Step 2: Signing with release.keystore..
Command:
• jarsigner –verbose –keystore [keystorefile] –signedjar [unalignedapk] [originalapk] alias\_name
Example:
• C:\Program Files\Java\jdk1.6.0\_43\bin> jarsigner -verbose -keystore release.keystore -signedjar "$1"\_unaligned.apk "$1".apk release
Step 3: Aligning
Command:
• zipalign -f 4 [unalignedapk] [releaseapk]
Example:
• C:\Users\G535940\Downloads\adt-bundle-windows-x86\adt-bundle-windows-x86\sdk\too
ls>zipalign -f 4 "$1"\_unaligned.apk "$1"\_release.apk
Step 4: Cleaning up
Command:
• rm 4 [unalignedapk]
Example:
• rm "$1"\_unaligned.apk
Additional Commands might help:
1. To generate new key with keytool
keytool -genkey -alias -keystore
2. To list keys
keytool -list -keystore
Command to generate a keyhash for the Facebook features
Command:
• keytool -exportcert -alias alias\_name -keystore [keystorefile] | openssl sha1 -binary | openssl base64
Example:
• C:\Program Files\Java\jdk1.6.0\_43\bin>keytool -exportcert -alias release -keyst
ore release.keystore |opens l sha1 -binary | openssl base64
Note:
To sign our apks we have downgraded JDK from 1.7 to 1.6.0\_43 update.
Reason:
As of JDK 7, the default signing algorithim has changed, requiring you to specify the signature and digest algorithims (-sigalg and -digestalg) when you sign an APK.
Command:
jarsigner -verbose -sigalg MD5withRSA -digestalg SHA1 -keystore [keystorefile]
[originalapk] alias\_name | Assuming your keys are stored in `keys.keystore`, you can run:
```
$ keytool -list -keystore keys.keystore
Your keystore contains 1 entry
your_key_alias, Jan 3, 2013, PrivateKeyEntry,
Certificate fingerprint (SHA1): 8C:C3:6A:DC:7E:B6:12:F1:4C:D5:EE:F1:AE:17:FB:90:89:73:50:53
```
to determine the alias of your key. Then run:
```
zip -d your_app.apk "META-INF/*"
jarsigner -verbose -keystore keys.keystore \
-sigalg MD5withRSA -digestalg SHA1 -sigfile CERT \
your_app.apk your_key_alias
```
to re-sign `your_app.apk` with the key named `your_key_alias`.
The extra `-sigfile CERT` option seems to be necessary as of JDK 8. |

1,397,496 | A colleague at work has a Kingston 240GB SSD drive which has come out of a now dead computer. We want to be able to recover some data from it (no backups sadly) however the drive won't mount properly.
I am using an Anker USB3 external HDD enclosure which I know to be working correctly. The drive has come from an Apple computer, and we are attempting recovery on another MacBook Pro.
The drive appears under DiskUtility, however is greyed out. Trying to click `mount` does nothing. FirstAid also fails.

So far, we've run `diskutil repairVolume disk2s2` which gave the following output:

**What Next?**
I am hopeful that with the drive being recognised, the data is still recoverable. Before looking at paid software such as DiskWarrior, is there anything else that I can try so that I can access the disk or to repair this `record count` problem. | 2019/01/23 | [

] | i tried @pragman solution and got the same fonts for all styles, but not defaults :(
so i removed the `webkit` option entirely, it was:
```
"webkit": {
"webprefs": {
"default_fixed_font_size": 13,
"default_font_size": 16,
"fonts": {
"sansserif": {
"Zyyy": "Custom"
},
"serif": {
"Zyyy": "Custom"
},
"standard": {
"Zyyy": "Custom"
}
},
"minimum_font_size": 0
}
},
```
my `Preferences` file was too big for vim editor and i got a new file with command-line JSON processor
```bash
jq -c "del(.webkit)" Preferences > Preferences.new
``` | You don't need to know the original fonts, here's how to do it:
First, close Google Chrome, so your changes don't get overwritten.
Go to your Google Chrome settings folder, in Ubuntu, i found it in `.config/google-chrome`
In this folder, open up the file `Default/Preferences`,
Search and replace references to your fonts in the file with the string "Custom". In my case they were all at the end of the file, so it was easy to replace.
After this, open up Google Chrome again, and your fonts will be reset. |

3,047,909 | On compilation of the CUDA SDK, I'm getting a nvcc fatal : Unsupported gpu architecture 'compute\_20' My toolkit is 2.3 and on a shared system (i.e cant really upgrade) and the driver version is also 2.3, running on 4 Tesla C1060s
If it helps, the problem is being called in radixsort.

] | I believe compute\_20 is targeting Fermi hardware, which you do not have. Also, Cuda 2.3 doesn't support Fermi features or compute\_20. Try using compute\_13 instead. | You are compiling the 3.x SDK with a 2.3 Toolkit, that won't work since as you've now seen compute\_20 is not supported.
The simplest solution is to either upgrade your Toolkit or downgrade your SDK. You could try changing the makefile (common.mk in C/common) on Linux or changing the Build Properties on Windows to select only compute\_13, but there may be other problems so it may be simpler to align the SDK/Toolkit versions.
Note that if you don't have administrator priviledges then you can install a local version of the Toolkit alongside the SDK but you would need admi to upgrade the driver. |
