] | Your problem is that you are converting your Collection/ArrayList to an array and then sort that Array.
Sorting that Array will have no effect on the original ArrayList.
If you want to sort your List you first need to declare it as a List, because Collections themself have no predefined order and therefor no sort method for them exists, and then in a second step use the corresponding method to sort that list:
```
public static void main(final String[] args) {
final List<Person> people = new ArrayList<>();
people.add(new Person("aaa", "hhh"));
people.add(new Person("aaa", "aaa"));
people.add(new Person("aaa", "uuu"));
Collections.sort(people, Comparator.comparing(Person::toString));
System.out.println(people);
}
```
Will output
>
> [aaaaaa, aaahhh, aaauuu]
>
>
> | Plot twist
The following
```
public static void main(String[] args) {
Person[] peopleArray = {
new Person("aaa", "hhh"),
new Person("aaa", "aaa"),
new Person("aaa", "uuu")
};
Collection<Person> people = Arrays.asList(peopleArray);
Arrays.sort(peopleArray, Comparator.comparing(Object::toString));
System.out.println(people);
}
```
Will print you the `[aaa aaa, aaa hhh, aaa uuu]` which is what you expect.
If you don't sort it and remove the line `Arrays.sort(peopleArray, Comparator.comparing(Object::toString));` it will print you the `[aaa hhh, aaa aaa, aaa uuu]`.
Reason why this would work -> `Arrays.asList()` is backed directly by the array, so when you sort the array you see the same sorting in the collection .
`java.util.ArrayList()` on the other side is not backed directly by any array that stores the elements since the `ArrayList` supports dynamic list size. |
10,843,929 | Really stuck with this question in my homework assignment.
Everything works, but when there is a space (`' '`) in the `p`. I need to stop the process of creating `can`.
For example, if I submit:
```
rankedVote("21 4", [('AB', '132'), ('C D', ''), ('EFG', ''), ('HJ K', '2 1')])
```
I would like to have:
```
['C D', 'AB']
```
returned, rather than just `[]` like it is now.
Code as below:
```
def rankedVote(p,cs):
candsplit = zip(*cs)
cand = candsplit[0]
vote = list(p)
ppl = vote
can = list(p)
for i in range(len(vote)):
if ' ' in vote[i-1]:
return []
else:
vote[i] = int(vote[i])
can[vote[i]-1] = cand[i]
for i in range(len(vote)):
for j in range(len(vote)):
if i != j:
if vote[i] == vote[j]:
return []
return can
```
**EDIT:**
In the example:
```
rankedVote("21 4", [('AB', '132'), ('C D', ''), ('EFG', ''), ('HJ K', '2 1')])
```
This means that the 1st, `AB` becomes 2nd,
and the 2nd one `C D` becomes 1st,
and it should stop because 3rd does not exist.
Let's say that instead of `21 4`, it was `2143`.
It would mean that the 3rd one `EFG` would be 4th,
and the 4th `HJ K` would be 3rd. | 2012/06/01 | [

] | Managed arrays are different than pointers. A managed array requires the size of the array, and if you're trying to marshal a struct, it requires a fixed size to marshal directly.
You can use the `SizeConst` parameter of the [`MarshalAs` attribute](http://msdn.microsoft.com/en-us/library/system.runtime.interopservices.marshalasattribute.aspx) to set the size of data when it gets marshaled.
But I'm guessing that `x` and `y` are the dimensions of the image and that the size of `data` depends on those variables. The best solution here is to marshal it over as an `IntPtr` and access the data when you need it:
```
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)]
public class IMAGE
{
public UInt32 x;
public UInt32 y;
private IntPtr data;
public byte[][] Data
{
get
{
byte[][] newData = new byte[y][];
for(int i = 0; i < y; i++)
{
newData[i] = new byte[x];
Marshal.Copy(new IntPtr(data.ToInt64() + (i * x)), newData[i], 0, x);
}
return newData;
}
set
{
for (int i = 0; i < value.Length; i++)
{
Marshal.Copy(value[i], 0, new IntPtr(data.ToInt64() + (i * x)), value[i].Length);
}
}
}
}
```
If you are allowed to use unsafe code, you can change the `IntPtr` to a `byte**` and work with it directly.
With the setter, you'll probably want to verify the dimensions of the value before you blindly write to unmanaged memory. | My guess is that it is:
```
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)]
public class IMAGE
{
public UInt32 x;
public UInt32 y;
public ref IntPtr data;
};

] | Scrypt and BCrypt are both extremely processor-intensive (by design). Because of this, I very much doubt any pure-python implementation is going to be fast enough to be secure - that is, be able to hash using a sufficient number of rounds within a reasonable amount of time.
I can personally attest to this, I've tried writing a pure-python BCrypt, and it was *way* too slow to be useful. The docs for the pure-python bcrypt implementation mentioned in another answer note this exact flaw - to beware of using it for actual security, it's rounds must be set too low. The only time such implementations will be fast enough is under pypy, which is not the situation you're faced with.
---
What you want to go with is something based on an available hash primitive like SHA-2. That way the heavy calculation bit will still be able to be written in C, even under GAE. I'd recommend something based on PBKDF2 or SHA-512-Crypt (note: this is *not* just a plain sha512 hash). The security of the algorithms is just as good, but pure-python implementations will be much more efficient, since they can leverage `hashlib` to do the heavy lifting.
The [Passlib](http://packages.python.org/passlib) library might be useful in this case, it contains implementations of [PBKDF2](http://packages.python.org/passlib/lib/passlib.hash.pbkdf2_digest.html) and [SHA-512-Crypt](http://packages.python.org/passlib/lib/passlib.hash.sha512_crypt.html) in pure python. *(Disclaimer: I'm the author of that library)*.

**DEF** A function $f:A\to \Bbb R$ is continuous at $a\in A$ if for every $\epsilon >0$ there exists a $\delta >0$ such that $$|x-a|<\delta\implies |f(x)-f(a)|<\epsilon$$
Put this in terms of open balls:
**DEF** A function $f:A\to \Bbb R$ is continuous at $a\in A$ if for every ball $B(f(a);\epsilon)$ there exists a ball $B(a;\delta)$ such that $$x\in B(a;\delta)\implies f(x)\in B(f(a);\epsilon)$$
But since $f(x)\in B(f(a);\epsilon)$ means the same as $x\in f^{-1}(B(f(a);\epsilon))$ we can phrase our definition as
**DEF** A function $f:A\to \Bbb R$ is continuous at $a\in A$ if for every ball $B(f(a);\epsilon)$ there exists a ball $B(a;\delta)$ such that $$B(a;\delta)\subseteq f^{-1}(B(f(a);\epsilon))$$
---
Now we're ready to prove what you claim, plus it's converse.
**THM** A function $f:S\subseteq \Bbb R\to \Bbb R$ is continuous if and only if for every open set $A\in \Bbb R$, $f^{-1}(A)$ is open.
**PROOF** Suppose first that $f$ is continuous, and pick an open set $A$. We want to prove that $f^{-1}(A)$ is open, that is, for every $x\in f^{-1}(A)$ there exists an open ball $B(x;\delta)\subseteq f^{-1}(A)$. Pick $y\in A$. We can assume $y=f(x)$ for some $x\in f^{-1}(A)$. Since $A$ is open, there exists an open ball $B(f(x);\epsilon)\subseteq A$. Using continuity, can you show there exists an open ball $B(x;\delta)\subseteq f^{-1}(A)$?
Conversely, suppose that for every open $A$, $f^{-1}(A)$ is open. In particular, for every open ball $B(f(x),\epsilon)$, $f^{-1}(B(f(x),\epsilon))$ is open, so it contains an open ball for each of its points. What does this tell you about the continuity of$f$? | Let $a$ is a point of $f^{-1}(A)$. By def. of $f^{-1}(A)$, $f(a)$ is an element of $A$. Since $A$ is open, there exists $r>0$ such that $B(f(a),r)\subset A$. Because $f$ is continous, there exists $\delta>0$ such that
$$|x-a|<\delta \implies |f(x)-f(a)|<r$$
for all $x$.
If you show that $B(a,\delta)\subset f^{-1}(A)$, then proof is completed, and it is easy to prove. |

202,758 | OK just before I start, I **do** know what does and doesn't constitute [valid housing](https://gaming.stackexchange.com/questions/22408/how-do-i-build-a-house-for-my-npcs) in Terraria. I'm also playing v1.2.4.1
What I'd like to know is does the "must have a door" requirement also mean "must be accessible", or can I create a walled-off cube with internal doors to satisfy the housing rules? i.e. are any of the houses A, B, C or D in the following diagram valid?
If I can, then I'm going to be making pressure-plate/activator automatic doors that don't get torn down in a blood moon. | 2015/01/23 | [

] | Assuming that all of those have walls and a light source, those would count as valid housing. The requirement is that it has a door, not that the door go anywhere. Also notable is that [wooden platforms count as doors for the housing rule](http://terraria.gamepedia.com/Guide:Base_defense_and_precautions#Reminder), so you can actually just have a wooden platform separate the rooms from each other as well.
Here is an example of housing with internal doors:

This is actually a very common strategy to defend from a blood moon. As noted in the [Base Defense Guide](http://terraria.gamepedia.com/Guide:Base_defense_and_precautions) on the Wiki:
>
> By using actuators and Grey, Brown, Blue or Lihzahrd pressure plates, you can create a player only door that doesn't even require you to use your mouse. Setup the door as you would an active stone/actuator door and because Grey, Brown, Blue or Lihzahrd pressure plates can only be activated by the player no mobs are able to enter (nor escape).
>
>
>
You can also just place a torch or other item in front of the door so that it can only be opened when you are facing towards the outside. [From the wiki](http://terraria.gamepedia.com/Guide:Base_defense_and_precautions#Possible_Methods):
>
> Another way to prevent enemies breaking down your door is to place a non-solid object, such as a chest, wooden platform or other Furniture item, on the inside of the door. This will prevent enemies from opening it but will require the player to face away from the house to open the door.
>
>
> | The structure does not have to be "accessible" with a door; as in you can create a switched active block entry way so that Blood Moon/Eclipse mobs can't get in. You can also create a double door entry way, where the outer door is the switched active blocks.
Another way, would be to place a platform, container or decoration against the door. This creates an "open from the inside only" door, that can't be opened inwards (the direction most mobs are headed to get inside your house). The exception to this is goblin armies, as they break the door instead of opening it. The "issue" is that YOU also can not open the door inwardly. You would have to face out and click to open the door.
In your diagram, the C/D version where there is a switched "ceiling" between the doors is a good way to do it. |

I think it would probably depend on three things; the mass of the disk, the surface area of the disk and the air pressure. (Possibly on the size and number of holes on the table as well) | 2018/10/14 | [

Note: The PHP manual (<http://php.net/manual/en/pdo.errorinfo.php>) does not define exactly what "last operation on the database handle" means, but if there was an issue with binding parameters, that error would have occurred inside PDO and without any interaction with the database. It is safe to say that if `$pdo->execute()` returns `true`, that `$pdo->errorInfo()` is valid. If `$pdo->execute()` returns `false`, the behavior of `$pdo->errorInfo()` is not explicitly clear from the documentation. If I recall correctly from my experience, execute returns `true`, even if MySQL returned an error, returns `false` if no operation was done. Since the documentation is not specific, it might be db driver specific.
This answer reflects practical experience as of when it was written in September 2012. As a user has pointed out, the documentation does not explicitly reaffirm this interpretation. It also may only reflect the particular database driver implementation, but it should always be true that if `$pdo->execute()` returns `true`, that `$pdo->errorInfo()` is valid.
You might also want to set *PDO::ERRMODE\_EXCEPTION* in your connect sequence. Exception handling makes it unnecessary to check and query the error.

``` | According to this question [Magento2 Rest Api Search Criteria not working properly!](https://magento.stackexchange.com/questions/172767/magento2-rest-api-search-criteria-not-working-properly)
you can add a "fields" parameter...
Not used it, but from the answer I guess it works...
**EDIT:**
Actually, from what I can tell, "fields" is used for restricting the data returned, not adding more data. |
9,335,282 | I build up my datagrid with bindnig source:

SqlDataAdapter adapter = new SqlDataAdapter(Datenbank.cmd);
dataSet1.Tables.Clear();
adapter.Fill(dataSet1, "Table");
bs = new BindingSource();

dataGridView1.DataSource = bs;

] | See the section called **State List** in this bit of documentation...[Drawable Resources](http://developer.android.com/guide/topics/resources/drawable-resource.html#StateList).
You can define two different `Button` xml files one for the transparent 'default' state and another with the button as Red for your 'pressed' state. You then define a `selector` which switches the drawable resources in the different states.
EDIT: As per devunwired's comment the Color State List resource is probably more suitable for just changing colours rather than the drawable itself. | I like the solution proposed by Konstantin Burov in the other issue: [Android customized button; changing text color](https://stackoverflow.com/questions/4692642/android-customized-button-changing-text-color)
You can actually manage more states than just pressed and normal. But it should solve the problem.
```
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Focused and not pressed -->
<item android:state_focused="true"
android:state_pressed="false"
android:color="#ffffff" />
<!-- Focused and pressed -->
<item android:state_focused="true"
android:state_pressed="true"
android:color="#000000" />
<!-- Unfocused and pressed -->
<item android:state_focused="false"
android:state_pressed="true"
android:color="#000000" />
<!-- Default color -->
<item android:color="#ffffff" />
</selector>
```
Then you can use that selector drawable in your button changing the text color attribute like below. Note that the selector in the example below is named "button\_text\_color"
>
> android:textColor="@drawable/button\_text\_color"
>
>
>
Using the same drawable approach you can also solve the background color of the button. Just remember that in the selector instead of using the "android:color" attribute you need to use the "android:drawable" attribute like below.
```
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Focused and not pressed -->
<item android:state_focused="true"
android:state_pressed="false"
android:drawable="#ffffff" />
<!-- Focused and pressed -->
<item android:state_focused="true"
android:state_pressed="true"
android:drawable="#000000" />
<!-- Unfocused and pressed -->
<item android:state_focused="false"
android:state_pressed="true"
android:drawable="#000000" />
<!-- Default color -->
<item android:drawable="#ffffff" />
</selector>
```
And then in the button itself do, note that this time the selector name is "button\_background"
>
> android:background="@drawable/button\_background"

You can actually manage more states than just pressed and normal. But it should solve the problem.
```
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Focused and not pressed -->
<item android:state_focused="true"
android:state_pressed="false"
android:color="#ffffff" />
<!-- Focused and pressed -->
<item android:state_focused="true"
android:state_pressed="true"
android:color="#000000" />
<!-- Unfocused and pressed -->
<item android:state_focused="false"
android:state_pressed="true"
android:color="#000000" />
<!-- Default color -->
<item android:color="#ffffff" />
</selector>
```
Then you can use that selector drawable in your button changing the text color attribute like below. Note that the selector in the example below is named "button\_text\_color"
>
> android:textColor="@drawable/button\_text\_color"
>
>
>
Using the same drawable approach you can also solve the background color of the button. Just remember that in the selector instead of using the "android:color" attribute you need to use the "android:drawable" attribute like below.
```
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Focused and not pressed -->
<item android:state_focused="true"
android:state_pressed="false"

<item android:state_focused="false"
android:state_pressed="true"
android:drawable="#000000" />

</selector>

``` | See the section called **State List** in this bit of documentation...[Drawable Resources](http://developer.android.com/guide/topics/resources/drawable-resource.html#StateList).
You can define two different `Button` xml files one for the transparent 'default' state and another with the button as Red for your 'pressed' state. You then define a `selector` which switches the drawable resources in the different states.
EDIT: As per devunwired's comment the Color State List resource is probably more suitable for just changing colours rather than the drawable itself. |

] | JDOM, like DOM, XOM, and all other in-memory-xml-model libraries will represent the entire XML document in memory. If you consider that most XML documents are singe-byte-encoded (UTF-8 or ASCII) and that is then converted to 2-byte chars in Java/Android, it is normal for in-memory XML representations to take about twice as much memory as the raw XML document.
Compared to others, JDOM is pretty respectful of memory usage (I am the maintainer, I am biased, but I have also tried really, really hard on the memory management side).
You could try using [the SlimJDOMFactory](http://jdom.org/docs/apidocs/org/jdom2/SlimJDOMFactory.html) as part of your document build, but that will not save you as much as you will need.
The same problem exists for all in-memory XML models, and (for different document sizes) on all platforms and system configurations.
The solutions are:
* find out [how much memory you re allowed](http://developer.android.com/training/articles/memory.html)
* don't have such big documents. A 72Meg document on Android seems .... redundant.
* to not parse the entire document at once, and to use streaming systems for parsing (SAX, etc)
* off-load the processing to a server app.
* others. | Use the [XmlPullParser](http://developer.android.com/reference/org/xmlpull/v1/XmlPullParser.html) class, as DarkDarker suggested. Use either the setInput() that takes a Reader or the one that takes an InputStream and an encoding name (probably "UTF-8"). Then you can just use the parser to move through the document one element at a time, building your list as you go.
All DOM approaches (including JDOM, dom4j, and others) are memory hogs since they build the entire document representation in memory. The actual memory usage is typically at least 4x the byte size of the document, between the overhead of strings (two bytes per character) and the overhead of objects for every component of the document. |

```c
if((strcmp(usernameServer, username) == 0) && (strcmp(passwordServer, password) == 0))
```
So testing if user AND password are both equal to the value you compare them to. | Comparing strings with `strcmp()`:
>
> This function starts comparing the first character of each string. If they are equal to each other, it continues with the following pairs until the characters differ or until a terminating null-character is reached.
>
>
>
Returns:
* <0 the first character that does not match has a lower value in ptr1 than in ptr2
* 0 the contents of both strings are equal
* >0 the first character that does not match has a greater value in ptr1 than in ptr2
---
So in order to see if the strings match you would check if the return value is 0:
```
if(strcmp(usernameServer, username) == 0 && strcmp(passwordServer, password) == 0)

```

You can use the undocumented `GV$` table function to run a query against all RAC instances to find out which ones have a bad clock.

It's not always clear exactly where the code is running, and you may have to create a PL/SQL function to ensure that the code is truly executing on the remote instance.
```
create or replace function get_sysdate return date is
begin
return sysdate;
end;

table(gv$(cursor(

**Any idea why? How can I fix it?**
**UPDATE 1**
It seems to me that it has to do with this library (from Google): **concurrentlinkedhashmap-lru-1.4.1.jar**.
But I searched the development computer's file system and found only the above mentioned version (1.4.1).
**UPDATE 2 - Solution**
After searching thoroughly I found that I had different version of **concurrentlinkedhashmap-lru-xxxx.jar** on my development machine's file system and somehow I "managed" to put two different versions in the build.
Meanwhile, I still get the same exceptions when using my library (which I've already tested) in order to establish a connection to OrientDb from within OpenFire since OpenFire uses another version of concurrentlinkedhashmap then the one being used by OrientDb (concurrentlinkedhashmap-lru-1.4.1.jar). | 2015/10/14 | [

] | `NoSuchMethodError` happens because at runtime, Java tried to call a method on an object, and found it didn't exist, in particular:
```
com.googlecode.concurrentlinkedhashmap.ConcurrentLinkedHashMap$Builder.maximumWeightedCapacity(J)Lcom/googlecode/concurrentlinkedhashmap/ConcurrentLinkedHashMap$Builder;
```
Of course, you'd expect the code wouldn't compile if that was the case, so this almost always means you've built against a different version of the class than the one provided at runtime - it's usually a versioning issue.
So, you should figure out which library you're getting `ConcurrentLinkedHashMap` from, and compare this with the version being used at runtime (how are you deploying this? Is it running straight from IntelliJ?). You're likely to find that they have different versions, and you'll need to alter your version to match. | Please go to the below link and download the JAR file,

EVE is damaged during a bank robbery, which triggers embedded memories from her creator, and a desire to seek out Dr. Simmons's father, who was abusive to her as a child. EVE indeed does have a nuclear bomb in her, which must be disarmed, triggered to go off within 24 hours after she gets into a car crash.
Areas where it doesn't match up are a later time frame, possibly a different gender for the android, and that the father and creator are different people. Also, EVE doesn't go to save humanity, but defeating her does save a significant part of the population around her.

] | I found this from googling, so its validity may be questionable, but it came up fairly often.
It seems that both underdog and top dog originated from dog fighting which went on in the 19th century. The losing dog ended up on the bottom, or **under** the winner, who was on **top**.
My reference is [The Times of India](http://articles.timesofindia.indiatimes.com/2004-07-17/open-space/27159778_1_origin-word-top-dog). | *Underdog*
----------
The "under dog" was the dog who lost a fight (as opposed to the winning "top dog"), and *underdog* has become idiomatic for the inferior person or party, or the one fighting a larger adversary.
The OED says it originates in the US and their earliest citation is the British *Daily Telegraph* of 1887:
>
> There is an indefinable expression in his face and figure of having been vanquished, of having succumbed, of having been ‘under-dog’ as the saying is.
>
>
>
I found an earlier citation from *[The Popular Science Monthly](http://books.google.fi/books?id=FSIDAAAAMBAJ&pg=PA761&lpg=PA761&dq=underdog%20OR%20%22under%20dog%22%20OR%20%22under-dog%22&source=bl&ots=agYnTeviMi&sig=dbB0BJWYAUT0MXLJuWoLok0luJk&hl=en&sa=X&ei=YtI_UOH-MIjh4QSPxYDoAg&redir_esc=y#v=onepage&q=%22under%20dog%22&f=false)* of April 1882, in an article called "Has Science Yet Found a New Basis for Morality?" by Professor Goldwin Smith and quoting Dr. Van Buren Denslow:
>
> But, if the **under dog** in the social fight runs away with a bone in violation of superior force, the top dog runs after him bellowing, "Thou shalt not steal," and all the other **top dogs** unite in bellowing, "This is divine law, and not dog law"; the verdict of the **top dog**, so far as law, religion, and other forms of brute force are concerned, settles the question.
>
>
>
And on the next page, Smith summarises:
>
> It appears that between one state and the other there may be an interval in which the question will be not between the moral and the immoral, but between the **top and the under dog**.
>
>
>
---
*Top dog*
---------
The "top dog" was similarly the dog that won the fight, and now figuratively refers to a winner or the best person, party or thing.
The earliest OED citation is from a 1900 edition of *The Speaker: A Review of Politics*:
>
> The most popular argument in favour of the war is that it will make the individual Briton top dog in South Africa.

----------
The "under dog" was the dog who lost a fight (as opposed to the winning "top dog"), and *underdog* has become idiomatic for the inferior person or party, or the one fighting a larger adversary.
The OED says it originates in the US and their earliest citation is the British *Daily Telegraph* of 1887:
>
> There is an indefinable expression in his face and figure of having been vanquished, of having succumbed, of having been ‘under-dog’ as the saying is.

*Top dog*

The "top dog" was similarly the dog that won the fight, and now figuratively refers to a winner or the best person, party or thing.

] | Cassandra isn't a classical column store. It stores all inserted/updated data together, organized first by partition key, and then inside partition by clustering columns/primary keys. Data could be in different SSTables when you update them at different time point, but the compaction process will eventually try to merge them together.
If you're interested, you can use `sstabledump` against data files and see how data is stored. There is also a [very good blog post from The Last Pickle about storage engine in the Cassandra 3.0](https://thelastpickle.com/blog/2016/03/04/introductiont-to-the-apache-cassandra-3-storage-engine.html) (it's different from previous versions). | Cassandra is basically a column-family database or row partitioned database along with column information not column based/columnar/column oriented database. When insert/fetch we need to mention partition(aka row key , aka primary key) column information. We can add any column at any point of time.
Column-family stores, like Cassandra, is great if you have high throughput writes and want to be able to linearly scale horizontally.
The term "column-family" comes from the original storage engine that was a key/value store, where the value was a "family" of column/value tuples. There was no hard limit on the number of columns that each key could have. |

] | Cassandra is not a *column-oriented* database, it is a *partition-row* store, this means that the data in your example will be stored like this:
```
"YourTable" : {
row1 : { "ID":1, "firstname":"fname1", "lastname":"lname1", "websitename":"site1", "timestamp":1582988571},
row2 : { "ID":2, "firstname":"fname2", "lastname":"lname2", "websitename":"site2", "timestamp":1582989563}
row3 : { "ID":3, "firstname":"fname3", "lastname":"lname3", "websitename":"site3", "timestamp":1582989572}
...
}
```
The data is grouped and searched based on the primary key (which is the partition key and could include one or several clustering keys).
Some things to consider:
* Cassandra is an append-only store, this means that when you try to update or delete a record, internally it will create a new record with the new value and a different timestamp; for the delete operation it will add a meta-data called "tombstone" that identifies the records that will be removed
* Adding or removing nodes to the cluster will trigger a rearrangement of the tokens distribution, this means that the instance or server where a record can be located or maintained may change | Cassandra is basically a column-family database or row partitioned database along with column information not column based/columnar/column oriented database.

38,863 | I have [multiple IP addresses](https://serverfault.com/questions/868/multiple-ip-addresses-per-nic) configured to a NIC in Windows 2003/2008 Servers.
This is done to get unique internal IPs to IIS websites, and there is a static NAT from each of these internal website addresses to corresponding public addresses. Each internal IP has a unique public IP.
Windows cmd and other applications use primary IP as a source IP by default.
But now I have a problem in that I would need to **initiate HTTP/HTTPS requests** from one of the secondary addresses to an external website that has allowed incoming traffic from only this secondary address.
Is it possible to assign source IPs to windows applications in a less intrusive way than setting the secondary IP as a primary IP in Windows, or switching public addresses in the NAT configuration? I don't want to hassle with NAT or IP settings in a production server with remote connections only.

] | The short answer is no, unless the application specifically supports it. Otherwise it's up to the IP stack to determine how things get sent out so doing something like putting a weight on one interface is what you have to do.
A workaround for a browser would be to install a local proxy. [**WebScarab**](http://www.owasp.org/index.php/Category:OWASP_WebScarab_Project) will allow you to do this, if you don't mind installing it on a server. You can set up a local proxy bound to a specific IP and then set your browser to use the local proxy. Thus the request will be sent to the remote server using the IP that the proxy is bound to.
If you use an internal proxy follow [**this guide**](http://www.owasp.org/index.php/Chaining_WebScarab_onto_another_proxy) to chain WebScarab to that proxy. | You can't do it from the web browser, but you can add a default route for a particular IP/subnet that uses the secondary IP.

If you're not in control of `PI`, you can evaluate `PI` first, then format it into the expression.
```
eval(f"2*({eval(PI)})") # or equivalently eval("2*({})".format(eval(PI)))
```
If you're not in control of `str1` either, you can replace all `PI` tokens with its literal string value: `1*pi`.
```
eval(str1.replace('PI', PI))
```
But this doesn't handle edge cases such as `2*PIE` (if they ever appear). A more robust solution would be use a regex and surround `PI` with `\b` characters to match a full token.
```
import re
eval(re.sub(r'\bPI\b', PI, str1))
```
This appropriately excludes strings such as `2*PIZZA` or `2*API`. | Thanks evaluating first seems to have solved the problem.

] | It so happens that there is a software only way to do this.
I was watching LinusTechTips and they were advertising this software on their end of video sponsor.
The software is called [Synergy](https://symless.com/synergy).
It actually works by creating some sort of local network and communicating over your own computers, making the experience very, very fast. The benefits of this over a hardware KVM switch is that this is software (not hardware duh ;)) and it is priced as low as $19, depending on the option you pick.
[The $19 option](https://symless.com/synergy/pricing) would be perfectly suitable for your needs, other options are encryption over the network, and unless your network is already insecure, you dont really need it.
As per a concern below, it runs on both wireless and wired connections!
Hope this is a suitable suggestion for you. | I'm having trouble finding anything that actually has all of the ports and connectors that (I think) you'll need, but I can explain how I would go about this. If you can get me specifics on what display outputs are available on your PC and laptop, as well as your monitor resolution and refresh rate, I'll take some time to find you the exact equipment.
---
What you want is a KVM switch, a mechanism designed to use one keyboard, mouse, and monitor (in your case two monitors) as a workstation that can dynamically swap between two computers. I recommend this over a standard dock for ease of use, flexible configurations, and preservation of desk surface real estate.
You've basically got two approaches. One is expensive and the other is somewhat convoluted.
<https://www.startech.com/Server-Management/KVM-Switches/>
That site is a good place to start, they make high end switches and they're just about the only company I can find that even does digital video formats or dual monitor outputs in any significant capacity. Almost everything else I've been able to pull up has been either analog (VGA) or DVI with maybe a few DVI-Dual Links in there. The downside of this approach is that you're probably going to drop $200+ on this solution.
The other method you could use would be to downgrade your cable connections to DVI (or whatever you can find that is compatible) and get two cheap units that handle single monitor outputs. This is still likely to run you $60+. There's also a concern about what resolution and refresh rate you're running at, as each type of cable has a ceiling on how much data it can transfer and thus what resolutions and frame rates it is capable of transmitting. I haven't found any single monitor HDMI or DisplayPort boxes that were cheap enough to consider over the StarTech products linked above, but you may have more luck. I searched Amazon, Newegg, and PCPartPicker if you were curious. Office Depot or Office Max might be worth a try.
PLEASE KEEP IN MIND: Most of these KVM switches do not come with extra cables, so plan your layout and figure out the types and lengths of cables you will need beforehand and order them alongside your KVM solution. This will save you headaches and irritation and time waiting for shipping.
Again, if you want to reply with those related specs that I mentioned above, I can find some time before Friday to help you hunt down specific hardware.

Keyboards are really up to you. If you don't mind a 60% board I can recommend an Anne Pro, I have one for work and love it; however, I haven't used it for gaming since it has a tiny layout and red switches. I can confirm though that it has built-in bluetooth (comes with dongle for non-BT devices) and hotkey device swapping for up to four connected devices, so it would fit your requirements there. Bonus points for being under $100 and having quality RGB because colors are fun. If that doesn't catch your eye, I know that Filco also has some good offerings, and CODE keyboards are always worth a look as well.

No. It's true that it's a special range, but it's reserved for *exactly the same purpose* as 192.168.0.0/16 – it is a private address block for LAN usage. (There is also a third block, 172.16.0.0/12. See the [IANA registry](https://www.iana.org/assignments/iana-ipv4-special-registry/iana-ipv4-special-registry.xhtml).)
All three private blocks act as normal unicast addresses and are routable locally, including between each other – they're just not routable across the global Internet. (What's actually dropped is traffic and route announcements *between ISPs.*)
So most likely you're pinging some host in your ISP's network, where they've decided to use 10.0.0.0/8.

* Don't use such buffers, they are dangerous. The C++ library provides you [std::string](http://en.cppreference.com/w/cpp/string/basic_string).

* There are an easier way to check for chars than this horribly long if. Hint: [std::string::find\_first\_of](http://en.cppreference.com/w/cpp/string/basic_string/find_first_of) |

* You probably want to use `i < strlen(str)` instead of `<=`, or you'll copy that terminating zero character twice.
* Your `scanf("%s", &again);` specifies to read a string, but you only have memory for a character, thus you probably end up writing into some random memory position.

9,712,606 | All,
I'm creating a side menu from a user defined menu in wordpress. I'm getting the menu options from the following code (since I know the menu id the user wants to display on the side):
```
$menu_items = wp_get_nav_menu_items($menu_id);
$menu_items = (array)$menu_items;
$output = '<div id="menu_options">';
$output .= '<ol class="tabs">';
foreach($menu_items as $menu){
$output .= '<li><a href="'.$menu->title.'" class="menu_page_id" id="'.$menu->ID.'">'.$menu->title.'</a></li>';
}
$output .= '</ol>';
$output .= '</div>';
$output .= '<div id="menu_content">This is content</div>';
$output .= '<input type="hidden" value="'.$menu_id.'" id="menu_id">';
return $output;
```
When a user clicks on one of the tabs I invoke an AJAX call to try and get the page content with the following code:
```
$('.menu_page_id').click(function(){
event.preventDefault();
page_id = $(this).attr("id");
menu_id = $('#menu_id').val();
action = "get_page_content";
$.post(ajaxurl, { page_id: page_id, menu_id: menu_id, action: action }, function(results) {
results = results.substring(0, results.length - 1);
$("#menu_content").hide();
$("#menu_content").html(results).fadeIn();
});
});
```
This calls the following function to return the content of the clicked page:
```
function get_page_content(){
$page_id = mysql_real_escape_string($_POST['page_id']);
$menu_id = mysql_real_escape_string($_POST['menu_id']);
$menu_items = wp_get_nav_menu_items($menu_id);
$menu_items = (array)$menu_items;
foreach($menu_items as $menu){
if($menu->ID == $page_id){
echo $menu->post_content;
}
}
}
add_action('wp_ajax_get_page_content', 'get_page_content');
add_action('wp_ajax_nopriv_get_page_content', 'get_page_content');
```
This all works good and it returns the page content except it just dumps the results out and actually doesn't display what I want with the shortcodes etc. Say I have the following on the page in Wordpress:
```

] | See my answer for the **Android Studio environment**, [Mac and “PANIC: Missing emulator engine program for 'arm' CPU.”](https://stackoverflow.com/a/52161215/8034839).
To solve this problem, you need to specify the `-kernel` path manually. i.e.
```
$ ~/Library/Android/sdk/emulator/emulator @Galaxy_Nexus_Jelly_Bean_API_16 -kernel ~/Library/Android/sdk/system-images/android-16/default/armeabi-v7a/kernel-qemu
```
Remember to change the emulator name `Galaxy_Nexus_Jelly_Bean_API_16` to your own emulator name.
Below command is to check the emulators available for command line.
```
$ ~/Library/Android/sdk/emulator/emulator -list-avds
```
And also, ensure that your **emulator path** is correct, i.e. the one located at `~/Library/Android/sdk/emulator/`. | Just wanted to share my experience on this problem. Consulting each of the answers here, it didn't match my situation. Having a system image for Android API 22 causes this error and the weird thing is that all of the environment variables pointing to the correct directories. It doesn't make sense.
@BuvinJ answer had shed some light into the problem. I did check on the path describe on his answer and yes my copy of system image resides under the subfolder default when I look on the user directory (on Windows).
The weird thing is, there is also an android-sdk folder in the ANDROID\_SDK\_ROOT so I thought maybe Eclipse is looking there. Digging through the subfolders I figured out that the directory looks like this:
```
android-sdk-windows\system-images\android-22\google_apis\armeabi-v7a
```
This directory resides on the ANDROID\_SDK\_ROOT. There is also another one residing at the user directory user/XXXX/android-sdk/.
Eclipse is expecting it here:
```
android-sdk-windows\system-images\android-22\default\armeabi-v7a
```
Just changed the directory as such and it works now. |

] | Another reason you can get this error is that Eclipse can't find the correct file.
Check out where Eclipse is looking for your SDK files. You can do this on the command line. Below is an example for the windows command prompt for an avd I created and named 'SonyTabletS':
```none
c:\Program Files (x86)\Android\android-sdk\tools> emulator @SonyTabletS -verbose
```
The first line returned shows where eclipse is looking for the SDK files and will look something like:
```none
emulator: found ANDROID_SDK_ROOT: C:\Program Files (x86)\Android\android-sdk
```
Make sure that location is correct.
In my case, `ANDROID_SDK_ROOT` was initially set incorrectly to my home directory. This is because I set it that way by blindly following the Sony Tablet S SDK install instructions and adding an `ANDROID_SDK_ROOT` environment variable with the incorrect path. | Update the following commands in command prompt in windows:
1. `android update sdk --no-ui --all`
It update your SDK packages and it takes 3 minutes.
2. `android update sdk --no-ui --filter platform-tools,tools`
It updates the platform tools and its packages.
3. `android update sdk --no-ui --all --filter extra-android-m2repository`
Those who are working with maven project update this to support with latest support design library which will include extra maven android maven Repository.
1. In the command prompt it asks you for Y/N. Click on the Y then it proceeds with the installation.
2. It updates all Kernel-qemu files and qt5.dll commands. so that the Emulator works fine without any issues. |

] | I updated my android SDK to the latest version (API 19). When I tried to run the emulator with phonegap 3, the build was successful but it ran the same issue.
In the AVD manager there was an existent device, nevertheless, its parameters were all unknown. Surely this occurs because I uninstalled the old sdk version (API 17) that returns a second error while attempting to remove the device. With the message: "device is already running"
To solve the issue, I went to the AVD's location in ~/.android/avd/ and removed manually the device directory.avd and device.ini file. Finally, in the the device manager I created a new AVD provided by the newest API.
This allowed phonegap to build and run the emulator succesfully
I hope this helps
Good day | For me Updating the **SDK Tools** fixed the errors.

I'm creating a side menu from a user defined menu in wordpress. I'm getting the menu options from the following code (since I know the menu id the user wants to display on the side):
```
$menu_items = wp_get_nav_menu_items($menu_id);
$menu_items = (array)$menu_items;
$output = '<div id="menu_options">';
$output .= '<ol class="tabs">';
foreach($menu_items as $menu){
$output .= '<li><a href="'.$menu->title.'" class="menu_page_id" id="'.$menu->ID.'">'.$menu->title.'</a></li>';
}
$output .= '</ol>';
$output .= '</div>';
$output .= '<div id="menu_content">This is content</div>';
$output .= '<input type="hidden" value="'.$menu_id.'" id="menu_id">';
return $output;
```
When a user clicks on one of the tabs I invoke an AJAX call to try and get the page content with the following code:
```
$('.menu_page_id').click(function(){
event.preventDefault();
page_id = $(this).attr("id");
menu_id = $('#menu_id').val();
action = "get_page_content";
$.post(ajaxurl, { page_id: page_id, menu_id: menu_id, action: action }, function(results) {
results = results.substring(0, results.length - 1);
$("#menu_content").hide();
$("#menu_content").html(results).fadeIn();
});
});
```
This calls the following function to return the content of the clicked page:
```
function get_page_content(){
$page_id = mysql_real_escape_string($_POST['page_id']);
$menu_id = mysql_real_escape_string($_POST['menu_id']);
$menu_items = wp_get_nav_menu_items($menu_id);
$menu_items = (array)$menu_items;
foreach($menu_items as $menu){

}
}
}
add_action('wp_ajax_get_page_content', 'get_page_content');

] | Here's my story. Under 'Actions' on the AVD manager, I viewed the details for the AVD which wasn't working. Scrolling down, I found the line:
```
image.sysdir.1: add-ons\addon-google_apis-google-16\images\armeabi-v7a\

I then navigated to this file at:
```

I found there was no kernel file. However, I did find a kernel file at:
```

So I copied it and pasted back into:
```

] | The "ARM EABI v7a System Image" must be available. Install it via the Android SDK manager:
Another hint (see [here](https://plus.google.com/u/0/108967384991768947849/posts/DSi3oAuNnS7)) - with
* Android SDK Tools rev 17 or higher
* Android 4.0.3 (API Level 15)
* using SDK rev 3 and System Image rev 2 (or higher)
you are able to turn on GPU emulation to get a faster emulator:

**Alternative 1**
Intel provides the "[Intel hardware accelerated execution manager](http://software.intel.com/en-us/articles/intel-hardware-accelerated-execution-manager/)", which is a VM based emulator for executing X86 images and which is also served by the Android SDK Manager.

Roman Nurik posts [here](https://plus.google.com/u/0/+RomanNurik/posts/iU5caAe7C6f) that the Intel emulator with Android 4.3 is "blazing fast".
**Alternative 2**
In the comments of the post above you can find a reference to [Genymotion](http://www.genymotion.com/) which claims to be the "fastest Android emulator for app testing and presentation".

**Editor's note**: By administrator mode, he meant Right-click > Run as administrator on windows platforms . | Just wanted to share my experience on this problem. Consulting each of the answers here, it didn't match my situation. Having a system image for Android API 22 causes this error and the weird thing is that all of the environment variables pointing to the correct directories. It doesn't make sense.
@BuvinJ answer had shed some light into the problem. I did check on the path describe on his answer and yes my copy of system image resides under the subfolder default when I look on the user directory (on Windows).
The weird thing is, there is also an android-sdk folder in the ANDROID\_SDK\_ROOT so I thought maybe Eclipse is looking there. Digging through the subfolders I figured out that the directory looks like this:
```
android-sdk-windows\system-images\android-22\google_apis\armeabi-v7a
```
This directory resides on the ANDROID\_SDK\_ROOT. There is also another one residing at the user directory user/XXXX/android-sdk/.
Eclipse is expecting it here:
```
android-sdk-windows\system-images\android-22\default\armeabi-v7a

This all works good and it returns the page content except it just dumps the results out and actually doesn't display what I want with the shortcodes etc. Say I have the following on the page in Wordpress:
```
[frame_left]<img src="http://www.website.com/wp-content/uploads/2011/10/pic.jpg" alt="" width="300" height="240" />[/frame_left]
<h2 style="margin: 25px 0 0 0;">Person</h2>
<span class="small"><em>Title</em></span>
<p style="text-align: justify;">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Mauris lacinia justo quis neque dapibus porta...</p>
[button link="http://www.google.com" text="Read More"]
[clear]
```
The following is what actually gets returned from my AJAX request:
```
[frame_left][/frame_left] Title Lorem ipsum dolor sit amet, consectetur adipiscing elit. Mauris lacinia justo quis neque dapibus porta...[button link="http://www.google.com" text="Read More"] [clear]
```
Is there a way to actually return a page's content through Wordpress and have it display the shortcodes, html etc correctly??
Thanks for any help you can shed on this situation!! | 2012/03/15 | [

] | If you know the kernel file is installed on your machine, then problem is getting emulator.exe to find it.
My fix was based on the post by user2789389. I could launch the AVD from the AVD Manager, but not from the command line. So, using AVD Manager, I selected the avd I wanted to run and clicked "Details". That showed me the path to the avd definition file. Within a folder of the same name, next to this .avd file, I found a config.ini file. In the ini, I found the following line:
```
image.sysdir.1=system-images\android-19\default\armeabi-v7a\
```
I looked in the folder C:\Users\XXXX\android-sdks\system-images\android-19, and found that the image.sysdir.1 path was invalid. I had to remove the "default" sub folder, thus changing it to the following:
```
image.sysdir.1=system-images\android-19\armeabi-v7a\
```
I saved the ini and tried again to launch the AVD. That fixed the problem! | I tried what ChrLipp suggested, but that wasn't the problem, as the image was already installed. What I did was run:
```
android avd
```
to start the emulator manually. Then I stopped the emulator, and form that point on the
```
cca emulate android
```
app started working, without the "missing a kernel file" error. |

```
$line = 'blabla translate("test") blabla';
$line = preg_replace("/(.*?)translate\((.*?)\)(.*?)/","$1".translate("$2")."$3",$line);

So the result should be that translate("test") is replaced with the translation of "test".
The problem is that translate("$2") passes the string "$2" to the translate function. So translate() tries to translate "$2" instead of "test".
Is there some way to pass the value of the match to a function before replacing? | 2010/03/31 | [

```
function translate($m) {
$x = process $m[1];
return $x;
}
$line = preg_replace_callback("/translate\((.*?)\)/", 'translate', $line);
``` | You can use the preg\_replace\_callback function as:
```
$line = 'blabla translate("test") blabla';

] | I have used SafetyNet API for accessing device's runtime env. I have kept signing certificate of app on server to verify its sha256 against what we get in the SafetyNet response. Below are the steps you can refer if applies to you too.
1. Get SHA256 fingerprint of signing X509Certificate
MessageDigest md = MessageDigest.getInstance("SHA-256");
byte[] der = cert.getEncoded();
md.update(der);
byte[] **sha256** = md.digest();
2. Encode sha256 to base64 string
String **checksum** = Base64.getEncoder().encodeToString(**sha256**)
3. Match **checksum** with **apkCertificateDigestSha256** of SafetyNet response | I think this can help you
1.Find AttestationStatement file in GG example. and add this function:
```
public String bytesToHex(byte[] bytes) {
StringBuffer result = new StringBuffer();
for (byte b : bytes) result.append(Integer.toString((b & 0xff) + 0x100, 16).substring(1));
return result.toString();
}
```
2.Find getApkCertificateDigestSha256 function and edit like this:
```
public byte[][] getApkCertificateDigestSha256() {
byte[][] certs = new byte[apkCertificateDigestSha256.length][];
for (int i = 0; i < apkCertificateDigestSha256.length; i++) {
certs[i] = Base64.decodeBase64(apkCertificateDigestSha256[i]);
System.out.println(bytesToHex(certs[i]));
}
return certs;
}
```
3.Find process() function in OnlineVerrify and add like this:
```
if (stmt.getApkPackageName() != null && stmt.getApkDigestSha256() != null) {
System.out.println("APK package name: " + stmt.getApkPackageName());
System.out.println("APK digest SHA256: " + Arrays.toString(stmt.getApkDigestSha256()));
System.out.println("APK certificate digest SHA256: " +
Arrays.deepToString(stmt.getApkCertificateDigestSha256()));
}
```
4. Now, run and you'll see the SHA-256 and let compare.
Not: there is no ":" charactor bettwen sha-256 generated cause i'm lazy. ^^. |
