I'm totally new to kotlin so I just installed IntelliJ on my pc for a course I'm taking.
Since I'm not new to programming using the autocomplete is merely to save a little time. I assumed it'd be enabled by default but it isn't the case.
After a little research I couldn't find any major answers whether the option was even there.
Based on [this answer](https://stackoverflow.com/a/61070133/6057960) about the topic I figured the feature does exists.
My question is, how do you enable the repl autocompletion feature? Am I missing something?
Thanks in advance. |

Rust has problems with generic reverse operator implementations (i.e. `impl<A, B> Op<A> for MyStruct<B>` is fine, `impl<A, B> Op<MyStruct<B>> for A` will not compile). Even if you manage to circumvent the overflow error (which is not possible in current Rust), you will still have problems with coherence, shown if you remove the first impl which causes the overflow:
```none
error[E0210]: type parameter `A` must be covered by another type when it appears before the first local type (`Field<B>`)
--> src/lib.rs:56:6
|
56 | impl<A, B, C> Mul<&Field<B>> for A
| ^ type parameter `A` must be covered by another type when it appears before the first local type (`Field<B>`)
|
= note: implementing a foreign trait is only possible if at least one of the types for which it is implemented is local, and no uncovered type parameters appear before that first local type
= note: in this case, 'before' refers to the following order: `impl<..> ForeignTrait<T1, ..., Tn> for T0`, where `T0` is the first and `Tn` is the last
```
What you want cannot be achieved in Rust.
On the other hand, you can make the non-reverse impls more general, by accepting both references and owned values:
```rust
impl<A, B> Mul<B> for Field<A>
where
A: Mul<B>,
{
type Output = <A as Mul<B>>::Output;
fn mul(self, other: B) -> Self::Output {
self.val * other
}
}
impl<'a, A, B> Mul<B> for &'a Field<A>
where
&'a A: Mul<B>,
{
type Output = <&'a A as Mul<B>>::Output;
fn mul(self, other: B) -> Self::Output {
&self.val * other
}
}

I have some very simple benchmark that is run via Catch2, and compiled with -O3 using `emscripten 3.1.37`:
```cpp
BENCHMARK("cpp sin only")
{
double sum = 1.0;
for (int t = 0; t < 2000000; ++t) {
sum += sin(double(t));
}
return sum;
};
#ifdef __EMSCRIPTEN__
BENCHMARK("js sin only")
{
EM_ASM_DOUBLE({
let sum = 1;
for (let i = 0; i < 2000000; i++) {
sum = sum + Math.sin(i);
}
return sum;
});
};
#endif
```
I would expect, that there wouldn't be a large difference between JavaScript and WebAssembly, but there is:
```
chrome:
benchmark name samples iterations est run time
mean low mean high mean
std dev low std dev high std dev
-------------------------------------------------------------------------------
cpp sin only 100 1 7.93775 s
79.3856 ms 79.147 ms 79.7195 ms
1.43061 ms 1.10437 ms 1.97222 ms
js sin only 100 1 2.21506 s
22.1354 ms 22.0064 ms 22.3 ms
742.138 us 614.746 us 901.128 us
```
Native, compiled with `GCC 12.3.0`, i get 24.2ms.
* To my understanding, JavaScript uses double precision floats for all numbers. So the comparison should be fair. When using float in the C++ version, it gets to 12ms in chrome, but that is still slower (and less precise). FF sits at around 30ms.
* <del>Maybe JavaScript uses a less precise, but faster implementation of sin and sqrt? Adding `-fast-math` doesn't increase performance for double. Float with fast-math in chrome becomes as fast as JavaScript, in FF it's still at around 30ms. </del>
* Is it, that WebAssembly isn't given as much time in the optimiser? That could explain, why it's so much slower in FF. But shouldn't emscripten take care of most of the optimisation?
* Could it be some sort of protection against meltdown/spectre?
**Update** (I ran several additional benchmarks on a request in the comments):
* g++12 is a bit faster than clang15, but that's within 10%
* performance of sqrt is almost equal between the versions (before there was a sqrt and a sin in the example)
* most of the time is spent in sin.
* **increasing the iteration count to 2 millions makes JS about 4x faster. increasing it to 5 millions increases the lead to 10x. JS is still about the same speed as C++ native.**
* note that the benchmark is execute 100 times by Catch2. The runtime of above code is around 1s.
* I verified that it's not as simple as JS using float. The webassembly c++ computation matches the JS result exactly.
* using 123456789042+1000000 increased the runtime by about 3-4x on gcc, clang native, webassembly c++ and js (the relative performance webassembly vs js stayed about the same).
* reference, this is the code i used: https://pastebin.com/Mu2barB6 and here are the results for chrome: https://pastebin.com/Hbte7yRj
**update 2:**
After [a comment](https://stackoverflow.com/questions/77989813/why-is-sin-slower-in-webassembly-than-in-java-script/78128153?noredirect=1#comment137937888_78128153) by user21489919, I [reported the issue to emscripten](https://github.com/emscripten-core/emscripten/issues/21660). |
You can achieve the desire animation using zoom in effect, we can learn it through the flutter doc, or refer below code.
[https://api.flutter.dev/flutter/widgets/ScaleTransition-class.html][1]
`class _ManageScale extends State<YourClass> with TickerProviderStateMixin{
late final AnimationController controller = AnimationController(
duration: const Duration(seconds:2),
vsync: this,
)..repeat(reverse:true) ;
late final Animation<double> _animation = CurvedAnimation(
parent: _controller,
curve:Curve.fastOutSlowIn,
);
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: ScaleTransition(
scale: _animation,
child: const Padding(
padding: EdgeInsets.all(8.0),
child: <Place_Your_Heart_Shape>(size: 150.0),
),
),
),
);
}
`
class _ManageScale extends State<YourClass> with TickerProviderStateMixin{
late final AnimationController controller = AnimationController(
duration: const Duration(seconds:2),
vsync: this,
)..repeat(reverse:true) ;//putting repeat reverse true is make your container big and small in same order
late final Animation<double> _animation = CurvedAnimation(
parent: _controller,
curve:Curve.fastOutSlowIn,
);
//for proper implementation of above stateful widget see doc
now use above animation as a property in your widget which is _animation
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: ScaleTransition(
scale: _animation,
child: const Padding(
padding: EdgeInsets.all(8.0),
child: <Place_Your_Heart_Shape>(size: 150.0),
),
),
),
);
}

Most commonly, you use `CStrBuf` when you have to pass a string buffer to a C API that is filled by the called function. Here is an example that calls `GetModuleFileName()` from C++ (off the top of my head).
```
// assume we got a valid HMODULE somewhere
HMODULE module = ...;
// somehow decide on a buffer size; for simplicity, use a constant here
DWORD size = MAX_PATH;
CString filename;
GetModuleFileName(module, CStrBuf(filename, size), size);
// the result is now in filename
// (note: error checks omitted for brevity)
```
`CStrBuf` has an `operator LPTSTR`, i.e., it can be converted to a writable string implicitly. For this reason, it can be written as a temporary object in place of an `LPTSTR` argument (the second argument in this example).
Note that `CStrBufT` is a class template just like `CStringT` is. Stick with the specialization `CStrBuf` that is akin to `CString`. |
I had a requirement to blur an image The 'Modifier.blur' is supported on Android 12 and above. I encountered problems (crashes) with some of the libraries mentioned earlier. After searching for various solutions, I ended up using this one, which works.
if you are looking to blur an image use this
implementation("com.github.skydoves:landscapist-transformation:2.1.6")
implementation("com.github.skydoves:landscapist-glide:2.3.2")
add these dependecies
use it like this
GlideImage(
modifier= Modifier
.padding(2.dp)
.width(64.dp)
.height(64.dp)
.clip(RoundedCornerShape(8.dp)),
imageModel = { imageUrl },
component = rememberImageComponent {
+BlurTransformationPlugin(radius = 10) // between 0 to Int.MAX_VALUE.
}
)
This configuration applies a blur transformation with a radius of 10 to your image. Adjust the radius as needed within the valid range from 0 to Int.MAX_VALUE

Your code have multiple issues, most of them syntactic ones. Let me try to rewrite it in a more _syntactically correct_ way. Then, you'll need to fix whatever semantics you want to give to it on your own:
```erlang
-module(divide).
-export([divide_the_cache/4]).
divide_the_cache(Cache, Divided, ThreadIndex, Acc)
when length(Cache) =< Acc ->
L = lists:merge(
[lists:nth(ThreadIndex, dict:to_list(Divided))],
[lists:nth(Acc, Cache)]
),
Conquered = dict:append(ThreadIndex, L, Divided),
NewThreadIndex =
case length(L) of
24 -> ThreadIndex + 1;
_ -> ThreadIndex
end,
divide_the_cache(Cache, Conquered, NewThreadIndex, Acc+1).
```
What I changed:
1. `-define` in Erlang is for macros and you were not using the `?divided` macro anywhere.
1. Variables in Erlang start in uppercase.
1. `case length(Cache) =< Acc of ThreadIndex ->` made no sense to me, so I replaced it with a guard (`when length(Cache) =< Acc`).
1. `Divided` should be either a dict or a list but it's treated as a list first and a dict later… so I decided that it's always a dict and thus, for `lists:nth/2`, I used `dict:to_list/1`.
1. In Erlang, expressions end in `,` (not `;`) and functions end in `.`.
1. You shouldn't write else-less if's in Erlang, so I turned your `if` into a `case` statement.
1. Variables in Erlang can't be re-bound, that's why I introduced `NewThreadIndex`. |
I’m making an in app purchase for my game on Steam. On my server I use python 3. I’m trying to make an https request as follows:
conn = http.client.HTTPSConnection("partner.steam-api.com")
orderid = uuid.uuid4().int & (1<<64)-1
print("orderid = ", orderid)
key = "xxxxxxxxxxxxxxxxxxx" # omitted for security reason
steamid = "xxxxxxxxxxxxxxxxxxx" # omitted for security reason
pid = "testItem1"
appid = "480"
itemcount = 1
currency = 'CNY'
amount = 350
description = 'testing_description'
urlSandbox = "/ISteamMicroTxnSandbox/"
s = f'{urlSandbox}InitTxn/v3/?key={key}&orderid={orderid}&appid={appid}&steamid={steamid}&itemcount={itemcount}¤cy={currency}&itemid[0]={pid}&qty[0]={1}&amount[0]={amount}&description[0]={description}'
print("s = ", s)
conn.request('POST', s)
r = conn.getresponse()
print("InitTxn result = ", r.read())
I checked the s in console, which is:
`s = /ISteamMicroTxnSandbox/InitTxn/v3/?key=xxxxxxx&orderid=11506775749761176415&appid=480&steamid=xxxxxxxxxxxx&itemcount=1¤cy=CNY&itemid[0]=cgdiamond5&qty[0]=1&amount[0]=350&description[0]=testing_description`
However I got a bad request response:
`InitTxn result = b"<html><head><title>Bad Request</title></head><body><h1>Bad Request</h1>Required parameter 'orderid' is missing</body></html>"`
How to solve this? Thank you!
BTW I use almost the same way to call GetUserInfo, except changing parameters and replace POST with GET request, and it works well. |

I have an application permission like `TeamsAppInstallation.ReadWriteSelfForUser.All`.
I also have some delegated permissions. <br> <br>
I want an admin to allow a small set of permissions including the `TeamsAppInstallation.ReadWriteSelfForUser.All` and few delegated permissions during the initial installation phase of an app. <br>
Later on, the admin can increment and allow all the permissions.<br><br>
Using the `/common/oauth2/v2.0/authorize?` endpoint by adding a `scope` param isn't supported for application permissions.
Using the `/common/adminconsent?` is not incremental, as it asks the admin to authorise all application and all delegated permissions.
How can incremental consent be achieved for the admin by allowing app permissions + some delegated permissions? Is there a different/better approach for this?

I'm trying to make an increment counter application in Jetpack Compose. I've divided each widget across separate files. I have the text widget that displays the number on one file, the button that increases the number on another file. and I'm putting them both together on the main file.
There is a problem when importing the widgets over to the main file. The function to increase the number is located in the file that the number text widget is located in, not the main file, so the function is not recognized.
Here is the file containing the number text widget and the function to increase the number.
@Composable
fun Number(){
var number by remember {
mutableIntStateOf(0)
}
fun increaseNumber(){
number++
}
Text(
text = number.toString(),
style = TextStyle(
color = Color.DarkGray,
fontSize = 30.sp,
)
)
}
Here is the file containing the button to increase the number.
@Composable
fun AddButton(onClick: () -> Unit) {
IconButton(onClick = onClick) {
Icon(
imageVector = Icons.Filled.Add,
contentDescription = "Add Button",
modifier = Modifier.size(width = 30.dp, height = 30.dp)
)
}
}
Here is the main file
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
MyApp()
}
}
}
@Composable
fun MyApp() {
MaterialTheme {
Surface(color = Color.White, modifier = Modifier.fillMaxSize()) {
MainPage()
}
}
}
@Composable
fun MainPage() {
Row (
horizontalArrangement = Arrangement.Center,
verticalAlignment = Alignment.CenterVertically
) {
AddButton(onClick = {increaseNumber()})
Number()
}
}
I have the increaseNumber() function in the onClicked parameter for the AddButton Composable but it won't recognize it because it's in a different file. How do I import the increaseNumber() function from the number file on to the main file. Thanks for any help. |
I am creating a memoization example with a function that adds up / averages the elements of an array and compares it with the cached ones to retrieve them in case they are already stored.
In addition, I want to store only if the result of the function differs considerably (passes a threshold e.g. 5000 below).
I created an example using a decorator to do so, the results using the decorator is slightly slower than without the memoization which is not OK, also is the logic of the decorator correct ?
My code is attached below:
import time
import random
from collections import OrderedDict
def memoize(f):
cache = {}
def g(*args):
if args[1] == 'avg':
sum_key_arr = sum(args[0])/ len(list(args[0]))
elif args[1] == 'sum':
sum_key_arr = sum(args[0])
print(sum_key_arr)
if sum_key_arr not in cache:
for key, value in OrderedDict(sorted(cache.items())).items():# key in dict cannot be an array so I use the sum of the array as the key
if abs(sum_key_arr - key) <= 5000:#threshold is great here so that all values are approximated!
#print('approximated')
return cache[key]
else:
#print('not approximated')
cache[sum_key_arr] = f(args[0],args[1])
return cache[sum_key_arr]
return g
@memoize
def aggregate(dict_list_arr,operation):
if operation == 'avg':
return sum(dict_list_arr) / len(list(dict_list_arr))
if operation == 'sum':
return sum(dict_list_arr)
return None
t = time.time()
for i in range(200,150000):
res = aggregate(list(range(i)),'avg')
elapsed = time.time() - t
print(res)
print(elapsed)
UPDATE: in this update I change the input to become a dict while I search for keys of them in the caching strategy :
import time
import random
from collections import OrderedDict
def memoize(f):
cache = {}
def g(*args):
key_arr = list(args[0].keys())[0]
arr_val = list(args[0].values())[0]
if key_arr not in cache:
for key, value in OrderedDict(sorted(cache.items())).items():# key in dict cannot be an array so I use the sum of the array as the key
if abs(value - arr_val) <= 5000:#threshold is great here so that all values are approximated!
return cache[key]
cache[key_arr] = f(args[0],args[1])
return cache[key_arr]
return g
#@memoize
def aggregate(dict_list_arr,operation):
if operation == 'avg':
return sum(list(dict_list_arr.values())[0]) / len(list(dict_list_arr.values())[0])
if operation == 'sum':
return sum(list(dict_list_arr.values())[0])
return None
t = time.time()
for i in range(200,5500):
res = aggregate({'1':list(range(10000))},'avg')
elapsed = time.time() - t
print(res)
print(elapsed)
The time elapsed is lower in decorated call which makes sense, now does this solve my question? |

What's wrong? |
Please consider the following case that would result in memory getting written after being deallocated.
The reason being that in `class PoorlyOrderedMembers` the member `m_pData` is declared after the member `m_nc` which means that the `std::unique_ptr` d'tor will be called and the instance of `ClassWithData` will be deleted just before the d'tor of `class NaughtyClass` will write to it.
While _writing_ it, you could probably get hints for a problem if you try to put both member initializations in the initializer list and get an error or a warning. Alternatively, you could change `NaughtyClass` and `PoorlyOrderedMembers` to use `std::shared_ptr` but, these are only obvious after you know that there's a problem here.
What would be the tell that something is wrong here when reviewing the code after the mistake was already made?
```c++
#include <cstring>
#include <memory>
class ClassWithData
{
char m_carray[32]{};
public:
char* data() { return m_carray; }
static constexpr size_t capacity() { return sizeof(m_carray); }
};
class NaughtyClass
{
ClassWithData* m_p = nullptr;
public:
~NaughtyClass()
{
char const m[] = "d'tor called";
memcpy(m_p->data(), m, sizeof m);
static_assert(sizeof(m) <= ClassWithData::capacity(), "the string doesn't fit in the capacity");
}
void set(ClassWithData* p) { m_p = p; }
};
class PoorlyOrderedMembers
{
NaughtyClass m_nc;
std::unique_ptr<ClassWithData> m_pData;
public:
PoorlyOrderedMembers() :
m_pData(std::make_unique<ClassWithData>())
{
m_nc.set(m_pData.get());
}
};
int main()
{
PoorlyOrderedMembers poom;
return 0;
}

is anyone else mildly annoyed that `char const m[] = "literal";` can't be written as `auto m = "literal";` |

I'm currently experimenting with the OpenCV library in C++. I've set up MinGW, CMake, and I'm coding in VSCode. However, I'm facing an inconvenience where I need to manually copy all the necessary DLL files into the project directory every time I want to run the executable program (.exe). Is there a configuration or setup that can help me avoid this constant copy-pasting of DLLs?
In CMakeLists.txt, I've already set:
set(OpenCV_DIR Path_to_opencv_lib)
find_package( OpenCV REQUIRED )
I'm unclear about why we need to copy DLLs into the current project directory in the first place.
Any assistance with these issues would be greatly appreciated. |

In C #12 in a nutshell, there was this claim.
"Parallel.Invoke still works efficiently if you pass in an array of a million delegates.
This is because it partitions large numbers of elements into batches that it assigns to a handful of underlying Tasks rather than creating a separate Task for each delegate."
Is there any evidence from Microsoft learn documentation or is it a claim from author after verifying it? |

I've just installed Wordpress 6.4.3 & MAMP and managed to edit functions.php and saved my changes.
When I tried to make more changes to the file, Wordpress started displaying the following error message:
> Something went wrong. Your change may not have been saved. Please try again. There is also a chance that you may need to manually fix and upload the file over FTP.
This is what I've added to functions.php
if ($_SERVER["REQUEST_METHOD"] === "POST") {
$name = sanitize_text_field($_POST["name"]);
$email = sanitize_email($_POST["email"]);
$message = sanitize_textarea_field($_POST["description"]);
// Add code to save the form data to the database
global $wpdb;
$table_name = $wpdb->prefix . 'request_form';
$data = array(
'name' => $name,
'email' => $email,
'description' => $message,
'submission_time' => current_time('mysql')
);
$insert_result = $wpdb->insert($table_name, $data);
if ($insert_result === false) {
$response = array(
'success' => false,
'message' => 'Error saving the form data.',
);
} else {
$response = array(
'success' => true,
'message' => 'Form data saved successfully.'
);
}
// Return the JSON response
header('Content-Type: application/json');
echo json_encode($response);
exit;
}
What I have done:
- I've checked permissions of the file and gave read and write access to everyone on my localhost.
- Restarted the server

You can use firebase storage to store the pdf file and retrieve it
store :
fun uploadPdf() {
val storageReference = FirebaseStorage.getInstance().getReference("pdfs/myfile.pdf")
val file = Uri.fromFile(File("path/to/your/file.pdf"))
storageReference.putFile(file)
.addOnSuccessListener {
}
.addOnFailureListener {
}
}
retrieve:
fun getPdfUrl(onResult: (String) -> Unit) {
val storageReference =
FirebaseStorage.getInstance().getReference("pdfs/myfile.pdf")
storageReference.downloadUrl
.addOnSuccessListener { uri ->
onResult(uri.toString())
}
.addOnFailureListener {
}
}

I’ve created a image from my partition with the e2image tool like this:
e2image -rap /dev/sdb2 /backup/sdb2.e2image
The Partitions size is around 870GB, but it used only around 25GB. When I do a `ls -laht` to check it size, I get this:
-rw------- 1 root root 868G 31. Mär 10:36 sdb2.e2image
Then I check the size with `du`
25G /backup/sdb2.e2image
now I created a lvm:
LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert
arch_root vg_arch -wi-a----- 30.00g
Now i want to restore my old partition backup, to this lv, so I do:
e2image -rap /backup/sdb2.e2image /dev/mapper/vg_arch_root
But i always get an error during the restoring process:
e2image no space left
What i'm doing wrong?

I wait until the page is loaded and use the "DOMContentLoaded" method to add eventhandlers on some p tags. This works until I open and close the modal, then the page/js freezes. Why does it freeze?

document.addEventListener("DOMContentLoaded", () => {
let test = document.querySelector("#div_1")
for (let i = 0; i < test.children.length; i++) {
test.children[i].addEventListener("click", () => {
console.log(test.children[i].innerHTML)

};
});
document.querySelector("#open_modal").addEventListener("click", () => {
if (!document.querySelector("#modal")) {
document.body.innerHTML += `

I'm hacking the Linux kernel v5.15 and try to debug it with `gdb` line by line. However, it seems that some line will be skipped. I find that the default compile optimization is -O2. So I changed the Makefile like:
```lang-make
ifdef CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE
KBUILD_CFLAGS += -O2 # here change to -O0
else ifdef CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3
KBUILD_CFLAGS += -O3
else ifdef CONFIG_CC_OPTIMIZE_FOR_SIZE
KBUILD_CFLAGS += -Os
endif
```
Then I compile again:
```lang-sh
make ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- -j$(nproc)
```
But it gives:
```lang-sh

Given a

hyphens: auto;
width: 86px;

This is a text that is long enough

By using words like
"incomprehensibilities",
we can demonstrate word breaks.
</div>
<!-- end snippet -->
I would like to access the formatted text with hyphenations with JavaScript to get a string similar to:
`"This is a text that is long enough to cause a line break if set so. By using words like "incomprehensibilit-ies", we can demon-strate word breaks."`.
N.B. hyphens in `incomprehensibilit-ies" and `demon-strate`.
Is this possible?
The use case is that I need a way to break and hyphenate text in a `<text>` element of an SVG by only using SVG elements.

Since you're initializing the state using `useState` with the prop `CurrentSelectedItem`, any changes to `CurrentSelectedItem` won't be reflected in the state of the component.
You can use the `useEffect` hook to update the state of `SelectedItem` whenever `CurrentSelectedItem` changes:
```javascript
function SelectedItem({ CurrentSelectedItem }) {
const [item, setItem] = useState(CurrentSelectedItem);
useEffect(() => {
setItem(CurrentSelectedItem);
}, [CurrentSelectedItem]);
...
}
```
Or if `SelectedItem` is solely dependent on `CurrentSelectedItem`, you can remove the local state in `SelectedItem` and directly use `CurrentSelectedItem` as a prop, like
```javascript
function SelectedItem({ CurrentSelectedItem }) {
return (
<div className="selected-item">
{/* <img src={CurrentSelectedItem.image} className="selected-image" /> */}
{CurrentSelectedItem.name}
{/* <QuantityBar itemCount={0} /> */}
</div>
);
}

If you have access to the users google drive account you can do an [about.get][1]
It returns an about object which contains a user object which ...
{
"displayName": string,
"kind": string,
"me": boolean,
"permissionId": string,
"emailAddress": string,
"photoLink": string
}
Gives you the users email address.

In all four cases you presented, Oracle would do a normal index seek (binary tree search) on the leading column `eid` because an equality predicate was provided for this column in each of your cases. But what else it does with the index depends on what other columns you're filtering on:
1. **First column** (`eid`) only: after finding the first `eid=10` entry in the leaf blocks using a binary search/seek, Oracle will scan that and any subsequent leaf blocks it needs to, moving through each block (single block reads) using a linked list, until it finds the first `eid` value that is not 10. As it does so it gathers `ROWID`s containing the table segment physical row address which it issues single block reads by `ROWID` to obtain the rest of the row.
2. **First two columns** (`eid` and `ename`): because `ename` is the second column in the index, Oracle will use both `eid` and `ename` together at the same time as it performs the binary search (seek) to find the first leaf block entry where `eid=10` and `ename='raj'`. It will then procede as above scanning leaf blocks until it finds the first row for which either of these columns have different values.
3. **First and third column** (`eid` and `esal`): because `esal` is the *third* column and you're skipping the second column, Oracle cannot use a single binary search/seek operation on `esal`. It has two choices:
3a. It does a binary search/seek only on the leading column, `eid`, but once it finds the first `eid=10` value in the leaf blocks it will do a normal scan of leaf blocks following that linked list - looking through *all* `eid=10` rows, but grabbing `ROWID`s only for those with `esal=1000`.
3b. Or, it does a skip scan: for every distinct value of the *missing intermediate column(s)* (`ename`), it will do a separate binary search/seek on the combined `eid=10 / esal=1000` value. This is a seek not a scan, but it is potentially many seeks. If there are many `ename` values this results in a lot of unnecessary single block I/O and can perform poorly. But if there are only a few values, it works pretty well.
4. **All columns**: Your last example would do a single binary search/seek on all three columns. Nothing special here.
You didn't offer this as an example, but to complete the study:
5. **Third column only**: If you queried on `esal=1000` only, Oracle could do one of the following:
5a. Forget the index and scan the table itself (most likely)
5b. Do a full scan (scattered read) of 100% of the leaf blocks of the index
5c. Do a skip-scan, which means a binary search/seek for `esal=1000` for every single distinct combination of the preceding,unfiltered columns (`eid` and `ename`). That would be a lot of seeks, so is rather unlikely the optimizer would choose it.
Whenever Oracle has a choice, it all depends on statistics and expected cardinalities from each operation which is largely driven by the min/max and # distinct values known for each column combined with overall table row counts. Of course you can force it with hints to if you think you know better than the statistics, but it is recommended to hold off on hinting until one has a solid grasp of how Oracle queries work internally, as you can easily tell it to do the wrong thing.

How can i add a theme toggle function to my html/css website so it changes the theme to dark and light/white in a button? I understand there's a bit of .js involved...
I got a code from [CSS-Tricks](https://css-tricks.com/a-complete-guide-to-dark-mode-on-the-web/#toggling-themes) and just coppied it, of course. But, I fail to make some of the text font colors change along with the rest of the fonts in the html. Can anyone assist because I even tried calling out the text classes themselves in the css query but it doesn't work. |

It clearly says on the doc. If you need to use latest generators then you must update the project to `ionic-angular >= 3.0.0`. Latest generators have tight coupling with the `ionic-angular` `module`.
**Note:** If you don't like to update latest then just create your components manually. No restrictions for that :)
> Generate pipes, components, pages, directives, providers, and tabs
> (ionic-angular >= 3.0.0)
You can read more about [it on the doc][1].
Update

If you need to update then you have to [do this changes][2] on your `package.json` file.
See also [this video upgrade guide][3]. This is for Ionic 3, but the concept is the same.

Currently, I am working on a project with Vite + React and now I want to dockerize it. Actually, I am beginner to docker. So, I need guidance on how to build the docker image and run it.
I tried once and it worked, but not as I supposed.
Can anyone help me with following,
- How to dockerize the react app with Vite?
- How to run the webapp on local host when developing?
- Hot Module Reload tool in Vite didn't work for me, how to fix it?
I used following commands in cmd:
`docker build .`
and
`docker run -p 5173:5173 0ac94edb8feb`
And here is my dockerfile:
```
FROM node:18-alpine
WORKDIR /app
COPY package.json .
RUN npm install
COPY . .
EXPOSE 5173
CMD ["npm", "run", "dev"]
```
Give me instructions to fix above issue. |

Basically, I am trying to remove special character from xml file. I have tried the below code. I have tested with regex tester. It's working fine. In the production machine, it is replacing string.Empty for = character which is valid.
`using System;`
`using System.Text.RegularExpressions;`
`class Program`
`{`
`static void Main(string[] args)`
`{`
`string xmlString = "<root><name>John & = Doe</name></root>";`
// Replace special characters with their XML entities
string cleanedXml = Regex.Replace(xmlString, @"[^\u09\u0A\u0D\u20-\uD7FF\uE000-\uFFFD\u10000-\u10FFFF]",
string.Empty);
Console.WriteLine(cleanedXml);
}
`}`
Culture : en-US in the prod machine.
Please anyone help me on this why it's happening. What's problem in the regex expression? Why regex is replacing equal symbol on prod machine alone? I am using. Net framework 4.8 version.
