en | I have a switch statement in a factory that returns a command based on the value of the enum passed in. Something like:
```
public ICommand Create(EnumType enumType)
{
switch (enumType)
{
case(enumType.Val1):
return new SomeCommand();
case(enumType.Val2):
return new SomeCommand();
case(enumType.Val3):
return new SomeCommand();
default:
throw new ArgumentOutOfRangeException("Unknown enumType" + enumType);
}
}
```
I currently have a switch case for each value in the enum. I have unit tests for each of these cases. How do I unit test that the default case throws an error? Obviously, at the moment I can't pass in an unknown EnumType but who's to say this won't be changed in the future. Is there anyway I can extend or mock the EnumType purely for the sake of the unit test? | ArmelR/stack-exchange-instruction | {

en | My understanding (erroneous as I may be told this is) is that iCloud is like a virtual external drive to some extent. Maybe that is my first mistake. But before everyone starts saying to look at other posts, please know I believe I have read all the posts about photo stream, camera roll, and the link that was posted (in one of these answers on this general topic) about iCloud backups, as well as those Q&A's related to freeing up space. I am still confused.
I am reaching storage capacity on my iPhone. I have a lot of photos on my phone because they've always migrated over from phone to phone every year or so. However, I need to free up some space and would like to delete photos from my iPhone (the device I took them on), but am still not sure if I do this, if it will remain on iCloud.
I have an iPad and a Macbook too, and they (the photos and docs) are on there, but with photos I just don't ever want to lose, I want to be sure that if I start deleting off my phone, and my computer gets stolen or dies and my iPad is broken or whatever, that I can still always access all of my photos by just logging in to iCloud from any device.
I (supposedly) have iCloud backing up all of these things. However, If I log into iCloud.com, I do not see my documents and photos. Shouldn't I conceivably be able to log in to iCloud.com from any device (Apple or not - say my work computer) and access my saved documents and photos?
Because I cannot go to iCloud.com (not settings/iCloud - bit iCloud.com) and see these things, I am hesitant to delete photos from my phone, depending on the idea that they are stored in iCloud. The same is true, to a different extent with my documents.
I have purchased extra storage on iCloud w/the idea that these things will always be there. What am I missing.
Also, aside from apps, photos and documents - are there some less obvious things I can delete that will free up space that would not be evident to the less than professionally savvy user? | ArmelR/stack-exchange-instruction | {

en | I am learning about shell scripting, particularly the shell commands `test`, `[ ]`. `[[ ]]` and `(( ))`, I wrote a real simple script to test my understanding, it takes in three arguments, if all three are integers (and the second argument is lower than the third) it tests if the first argument lays in the range between the second and third. Here it is:
```
#!/bin/bash
#test if arg1 is contained in the range [arg2, arg3]
function isint()
{
if [[ "$1" =~ ^-?[0-9]+$ ]]; then
echo $1 is integer
return 0
else
echo $1 is not integer
return 1
fi
}
if [[ $(isint $1) && $(isint $2) && $(isint $3) && $2 -lt $3 ]]; then
if [[ $2 -le $1 && $1 -le $3 ]]; then
echo "$1 is in the range [$2,$3]"
else
echo "$1 is not in the range [$2,$3]"
fi
else
echo usage: $0 INT1 INT2 INT3
fi
```
Here is my problem: the preceding script doesn't work, the
```
if [[ $(isint $1) && $(isint $2) && $(isint $3) && $2 -lt $3 ]]
```
never evaluates to true, if I want to obtain the wanted result I need to change the test to:
```
if [[ !$(isint $1) && !$(isint $2) && !$(isint $3) && $2 -lt $3 ]]
```
I don't get why this is working, the way I understood the `test`and `[[ ]]` commands is that they both evaluate the expressions passed to them, `0` evaluates to true and `1` evaluates to false. In my case if the correct parameters are passed to the script, the `isint` calls evaluate to 0, hence true, why the need for inverting them for the script to work as I want ?

en | I'm studying Hazewinkel's "Formal Groups" book, and example of a non-commutative group law is given by:
on the ring $\mathbb{F}\_p[c]/(c^2)$ we define
$$F(X,Y)=X+Y+cXY^p.$$
I see how to prove everything except non-commutativity- my problem is I tried to find example where it fails for $p=3$ and I keep getting that this is commutative (I am making mistake somewhere):
1. I think that elements in $\mathbb{F}\_3[c]/(c^2)$ can be seen as polynomials of degree $1$ or $0$, ie. elements are of form $a\cdot c+b$.
2. Also, since characteristic of ring is $3$ we have $(a\cdot c+b)^3=a^3c^3+b^3=b$ so
3. if $F(X,Y)=F(Y,X)$ than since $X+Y=Y+X$ we must have $cXY^p=cYX^p$
4. Let $X=ac+b$ and $Y=Ac+B$ then $cXY^3=c(ac+b)(Ac+B)^3=$(step 2)$=c(ac+b)B=bBc$
5. and $cYX^3=c(Ac+B)(ac+b)^3=$(step 2)$=c(Ac+B)b=bBc$
which leads to conclusion it is commutative. Which steps are wrong? | ArmelR/stack-exchange-instruction | {

en | Is MAC Viva Glam I better for warm olives? While rummaging through my old makeup at my mum's house, I found an old tube of MAC Viva Glam I. It was the first red lipstick I ever bought. And it was the lipstick that made me think I couldn't wear red. It pulled very brown and orange, and the skin on my upper lip turned green.
Fast forward years down the road. I've figured out I'm a light-medium probably cool-neutral olive with a lot of facial redness. My lips are mauve, which is why dusty pinks and mauves are my BFFs. And I've recently rediscovered reds.
My current HG red is Maybelline's Siren in Scarlet, and I also look good in the following:
#
* NARS Cruella
* NARS Provocative Red
* Revlon Blake's Red
* Revlon Julianne's Red
* UD Gash
*UD Rocksteady
So I'm wondering why Viva Glam I looks bad on me when it technically should look good? Is it because of the brown mixing with my mauve-ish lips? Or is it because I'm most likely a cooler olive? | nreimers/reddit_question_best_answers | {

en | A requirement of the product that we are building is that its URL endpoints are semantically meaningful to users in their native language. This means that we need UTF-8 encoded URLs to support every alphabet under the sun.
We would also not like to have to provide installation configuration documentation for every application server and version that we support, so it would be nice if we could accomplish this in-code. This might not be possible, since by the time that the Servlet has received the request, its been encoded by the App server, etc.
I've gotten this working (for my first use case using ISO-Latin non-US ASCII characters) by reconstituting the request's path info with:
```
String pathInfoEncoded = new String(httpServletRequest.getPathInfo().getBytes(), "UTF-8");
```
and then parsing that.
However, this doesn't work after redirecting from a POST to a GET using sendRedirect(). The request's path comes in already escaped (so ö is encoded as %F6) and my method above doesn't work.
So I guess my question is am I going about this all wrong? And if so, whats the antidote to my ignorance? :)
Update : found the solution. The problem is that the Servlet API has some weird behaviour with regards to URL encoding before sending the redirect. You have to URL-encode (escape the UTF-8 characters) BEFORE you call sendRedirect(). The encodeRedirectURL() method doesn't do it for you.

en | I've looked all over for information but I just don't understand how the state by state votes are tallied during the convention. After watching the DNC broadcast tonight I was confused to see that Biden, despite losing California and Nevada's primaries to Sanders, had more votes cast for him in each state during the "roll-call."
I understand that there were previously unpledged superdelegates which have since been all but abolished before this primary, so how does Biden come away with more votes in two states which he lost? The California votes tally up to 494 so that makes sense, but Biden ended up with nearly 100 more votes than he got in the primary which he lost.
I assume that some votes were "given up" from the Warren campaign or whatever, and that Biden also received the remaining 79 or so unpledged delegates, but then I thought that these delegates were no longer able to vote for whoever they wanted. Anyway any information on how this works would be great. Thanks! | ArmelR/stack-exchange-instruction | {

en | Built-in prius car heater at -20° F? Hi,
I just wanted to ask if it's okay to run car heater continuously for 12 hours while the car is idle but ignition is on and in ready to drive position.
I know that it will burn gas. That is okay with me. I just want to know if it will cause damage to the engine or transmission. Sorry my car knowledge is non-existent.
I will need to do this every night. Run the car and the heater continuously every night for 12 hours. And as I see the weather, it will remain in the negative teens for a couple of weeks at least. | nreimers/reddit_question_best_answers | {

Basically, you have a word that has spaces in it like c\_t.
You have a word bank and have to find all the possible words that can be made with the given string. So for in this case, if cat was in the word bank we would return true.
Any help on solving this question (like an optimal algorithm would be appreciated).
I think we can start with checking lengths of strings in the word bank and then maybe use a hashmap somehow. | ArmelR/stack-exchange-instruction | {

en | Years ago I had a little `#define` which I used in Borland C++ Builder. From memory, it was something *approximately* like
```
#define BREAK_IF_DEBUGGING asm(0xA3);
```
or something like that. It relied on 0XA3 (or whatever it was) being the op code for the interrupt which Borland were using to trigger a breakpoint.
Can I do the same thing in Eclipse? (I'll probably wrap it in a few `#idef ECLIPSE` and `#ifdef TESTING`)
What I hope to achieve here is that
- the code compiles away to nothing in the release version, of course.
- if I run by unit tests with Ctrl-F11 then I don't want a breakpint to be triggered (which it won't because of Ctrl-F11 being "Run")
- if I "Run with Debug" using F11) then if executions hits any use of the macro then it will stop at a breakpoint.
Why? Because I want to set & forget. Just put one of these in each error leg (or embed it in my `LOG_ERROR` macro).
Often when I choose my initial breakpoint, it is too late, so this macro says "I think I want to run to line X, but if execution passes through one of those error branches first, I'd like to stop there & sniff around".
Whether you like the idea or not, can you tell me how to do it? | ArmelR/stack-exchange-instruction | {

en | Currently, if your accounts are associated there's a button to let you disassociate them.
I really think we ought to kill this feature. Its pretty worthless as is and adds a lot of (error causing) complexity to account management.
But first, some numbers since we all love data.
On Stack Overflow, **206** users have disassociated their accounts and remained unassociated (0.1% of >1 rep users). Only 2,588 have ever disassociated their accounts.
This is not a terribly popular feature.
And what's the point? To hide your behavior on other sites\*?
There is a lot of complexity making this possible at all, and it would be much simpler\*\* to just treat "related accounts" as associated without an explicit association step. It would also eliminate [some](https://meta.stackexchange.com/questions/88223/wordpress-account-not-showing-up-on-stackexchange) [recurring](https://meta.stackexchange.com/questions/86044/no-mathematics-account-listed-on-stackexchange-com) [issues](https://meta.stackexchange.com/questions/87731/network-profile-doesnt-list-all-accounts/87733).
To be clear, I'm **not** suggesting a policy of "if you have accounts on two sites, they must be associated." Just that if you signup with the same OpenId on two sites, they would be; you would remain free to use distinct identifiers and retain distinct accounts.
So, are there any good reasons for the disassociate button to remain around? Or is it finally time to kill it?
\*Protip, doesn't work since moderators can see some of your "related accounts."
~~\*\*One of the grand simplifications would be being able to treat "once associate" as "always associated," which would let us kill some ugly GUIDs. Network account links, for example.~~
\*\*On further reflection, it'd actually be simpler to just always do a lookup by identifiers; so disassociation would remain possible by changing ids, but your accounts would need to actually be disjoint in terms of identifiers. | ArmelR/stack-exchange-instruction | {

en | TL;DR
Querying data from a two table database I've setup a long time ago takes a really long time to execute.
---
Back when I was a student, quite some time ago, I developed a simple survey tool for a college project. I later launched it as a free service for fellow students to use. Now, many, many years later, my survey tool still gets used by students. I kind off neglected the tool for long time until I recently tried it again and noticed it has become painstakingly slow when viewing survey results. Oops. There are much beter survey tools/services available now. However, the collected survey data is still valuable to many people I guess. I wrote it in PHP with a MySQL database. The database contains well over 6,000 different surveys.
I am familiar with MySQL, but I am by no means a database expert. I certainly wasn't back then and I suspect I made some poor choices structuring the database.
Depending on the number if participants to a survey, running a query to filter results from a single survey can take up to 12 seconds(!). I upgraded to a better server, but this didn't helped as much as I hoped it would. It only slightly improved the query time back from 18 to 12 seconds.
Because of the required flexibility (every survey has different questions) I setup two database tables. On the main table all the fixed data gets inserted, such as unique record ID, timestamp, users IP address, ect. The second table is used insert all the answers on; one record for each answer on each question. To get all the answers the seconds table gets 'pivoted' using Case statement in the SQL query (shown below). I think this might not have been the most efficient setup, and maybe this is the reason to why filtering results is really slow.
So, this is how I structured the database.
The main table with fixed data (`form_submits`)
```
+--------------------+--------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+--------------------+--------------+------+-----+---------+----------------+
| id | bigint(20) | NO | PRI | NULL | auto_increment |
| formid | mediumint(9) | NO | MUL | NULL | |
| email | varchar(255) | NO | MUL | NULL | |
| status | tinyint(1) | NO | | NULL | |
| submit_date | int(11) | NO | | NULL | |
| submit_ip | varchar(46) | NO | | NULL | |
| submit_ua | text | NO | | NULL | |
| confirm_date | int(11) | NO | | NULL | |
| confirm_ip | varchar(46) | NO | | NULL | |
| notifications_send | tinyint(4) | NO | | NULL | |
| notification_last | int(11) | NO | | NULL | |
+--------------------+--------------+------+-----+---------+----------------+
```
The data table with the questions and answers (`form_submits_data`)
```
+-----------+--------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-----------+--------------+------+-----+---------+-------+
| submit_id | mediumint(9) | NO | PRI | NULL | |
| form_id | int(11) | NO | MUL | NULL | |
| field_id | mediumint(9) | NO | PRI | NULL | |
| question | text | NO | | NULL | |
| answer | text | NO | | NULL | |
+-----------+--------------+------+-----+---------+-------+
```
If, for example, I want to get all the answers from participants that live in a certain postcode area this query is used:
```
SELECT
fs.id,
fs.email,
coalesce(MAX(case when field_id = 10 then answer end), 0) as 'C10',
coalesce(MAX(case when field_id = 11 then answer end), 0) as 'C11',
coalesce(MAX(case when field_id = 12 then answer end), 0) as 'C12',
coalesce(MAX(case when field_id = 15 then answer end), 0) as 'C15',
coalesce(MAX(case when field_id = 16 then answer end), 0) as 'C16',
coalesce(MAX(case when field_id = 17 then answer end), 0) as 'C17',
coalesce(MAX(case when field_id = 21 then answer end), 0) as 'C21',
coalesce(MAX(case when field_id = 32 then answer end), 0) as 'C32',
coalesce(MAX(case when field_id = 36 then answer end), 0) as 'C36',
coalesce(MAX(case when field_id = 38 then answer end), 0) as 'C38',
coalesce(MAX(case when field_id = 340 then answer end), 0) as 'C340',
coalesce(MAX(case when field_id = 341 then answer end), 0) as 'C341',
coalesce(MAX(case when field_id = 342 then answer end), 0) as 'C342',
coalesce(MAX(case when field_id = 343 then answer end), 0) as 'C343',
coalesce(MAX(case when field_id = 344 then answer end), 0) as 'C344'
FROM `form_submits` fs
LEFT JOIN `form_submits_data` fsd ON fsd.submit_id = fs.id
WHERE fs.form_id = 45023
AND fs.status = 1
GROUP BY fs.id
HAVING C32 LIKE 'HA0 1AA%'
ORDER BY fs.submit_date DESC
```
Which on a survey with 21,000 responses takes 12 seconds to execute. I feel this can't be right and thats this is probably because I structured the database poorly. **This makes me wonder, what should I have done differently? What setup/structure would be more efficient while retaining flexibility?** | ArmelR/stack-exchange-instruction | {

en | I have one server with 2 databases, and i want to replicate several tables from one database to another. Purpose is that we uses same user's table that used in projects.
As in anothers tables used InnoDB with foreign keys to users table i've chosen a replication way.
For that I made the changes for my.cnf
```
master-user=root
server-id = 2
replicate-rewrite-db = dou->jobs
replicate-do-table = jobs.auth\_user
replicate-wild-do-table = jobs.geo\_%
replicate-do-table = jobs.user\_profile
replicate-same-server-id = 1
report-host = master-is-slave
binlog-do-db = dou
log-bin
```
after syncing tables from `binlog-do-db` and starting slave error.log next lines appears:
```
111112 15:10:22 [Note] 'CHANGE MASTER TO executed'. Previous state master_host='localhost', master_port='3306', master_log_file='', master_log_pos='4'. New state master_host='localhost', master_port='3306', master_log_file='mysql-bin.000074', master_log_pos='106'.

We talked alot about sex, and i don't want to get catfished. How do I actually proceed fucking her on the first date? she's probably willing if we hit it off. She told me that we could probably fuck on the second date if everything goes well, but who has time for that shit?
We're going out for a drink, and then should I ask her if she wants to come over for a "movie"? Or is that too obvious?
What is my course of action after establishing a connection and a willingness for a meetup/hookup?

en | I'm hoping someone can help me since I am new at VBA. I have a spreadsheet with 200 command buttons on it. I want to be able to change the backcolor of a button based on the value in a cell. The names for the 200 buttons are FACopy1 through FACopy200. The code below works for changing a specific button (in this case FACopy1).
```
ActiveSheet.FACopy1.BackColor = RGB(0, 255, 255)
```
However, I want the button that changes to be based on a cell value. For example, If the cell value is 7 then it will change the color of FACopy7. I want something like this:
```
ActiveSheet.FACopy(cell value).BackColor = RGB(0, 255, 255)
```

en | I am trying to open a public company page on Linkedin using [Puppeteer](https://github.com/puppeteer/puppeteer), but every time it is redirected to an authentication form. This does not happen when I manually paste the URL in Chromium or in Chrome.
This is the code:
```js
const puppeteer = require("puppeteer");
(async () => {
const url = "https://www.linkedin.com/company/google/";
const browser = await puppeteer.launch({
headless: false,
args: [
"--lang=en-GB",
"--no-sandbox",
"--disable-setuid-sandbox",
"--disable-gpu",
"--disable-dev-shm-usage",
],
defaultViewport: null,
pipe: true,
slowMo: 30,
});
const page = await browser.newPage();
await page.goto(url, {
waitUntil: 'networkidle0',
});
await page.waitForSelector(".top-card-layout__entity-info-container", { timeout: 10000 });
await page.close();
await browser.close();
})();
```
This is where the browser is redirected:
[](https://i.stack.imgur.com/rTuu0.png)
This does not happen if I manually paste the URL `https://www.linkedin.com/company/google/` in Chromium or Chrome.
What I have tried so far:
* Use an `incognito` browser context:
```js
// [...]
const context = await browser.createIncognitoBrowserContext();
const page = await context.newPage();
// [...]
```
* Use [puppeteer-extra-plugin-stealth](https://www.npmjs.com/package/puppeteer-extra-plugin-stealth) to avoid being detected as bot:
```js
const puppeteer = require("puppeteer-extra");
puppeteer.use(require("puppeteer-extra-plugin-stealth")());
// [...]
```
* [Random user agent](https://www.npmjs.com/package/random-useragent)
```js
const randomUserAgent = require("random-useragent");
// [...]
await page.setUserAgent(randomUserAgent.getRandom());
// [...]
```

en | I am working with WPF and the MVVM Light framework. In my project I have a `GameViewModel` and an associated view for it that acts as the main screen of my game (this is not my main ViewModel). Within the GameView, I would like to dynamically display other UserControls, triggered by button clicks or something of that nature, at a certain location within the grid. I'm not entirely sure how to go about this. I thought about using a secondary ViewModelLocator or something similar (which I wouldn't be sure how to go about doing at all), but before I dove into that I thought I'd ask here and see if there are any more practical ways to do this.
Say a button is clicked, UserControl1 is displayed at 3, 3 on the grid, then another button is clicked and UserControl2 is displayed at the same location. This is essentially what I'm trying to accomplish. While it is not imperative, I would like to use as much XAML and as little code-behind as possible, but anything that gets the job done in an MVVM-friendly manner will work perfectly fine for me. Any advice that you could give would be greatly appreciated. I'm guessing the solution is probably a lot easier than I'm making it out to be... it usually is. | ArmelR/stack-exchange-instruction | {

en | I'm making a WebExtension for Chrome and Firefox that adds more information to GitHub. It's supposed to be faster than existing extensions.
I have my manifest set up like Mozilla's documentation recommends.
```
{
"manifest_version": 2,
"name": "GitHub Extended",
"version": "0.0.1",
"description": "Adds information to GitHub normally accessible only by the API.",
"permissions": [
"https://github.com/*"
],
"content_scripts": [
{
"all_frames": true,
"run_at": "document_start",
"matches": [
"https://github.com/*"
],
"js": [
"source/github.js",
"source/repository.js"
]
}
]
}
```
When the page is loaded, the content scripts are injected. The file `github.js` is a light wrapper around GitHub's API, and `repository.js` is the code to modfy the DOM of the main repository root page.
The most important code in there is this the preloader, which makes an API request while the page is loading and waits for both events to complete before adding to the DOM.
While this [current code](https://github.com/spikespaz/github-extended) works fine in Chrome, in Firefox it simply does nothing. I tried testing it by putting `console.log("I'm loaded!");` in `repository.js`. Nothing is printed. Why is this code not working in Firefox?
```
function beginPreload() {
console.log("Test from preload scope!");
let urlMatch = window.location.pathname.match(/\/([\w-]+)\/([\w-]+)/);
console.log(urlMatch);
Promise.all([
getSortedReleases(urlMatch[1], urlMatch[2]),
documentReady()
]).then((values) => {
let releaseJson = values[0];
let actionsEl = document.getElementsByClassName("pagehead-actions")[0];
let dlCount = 0;
for (release of releaseJson)
for (asset of release.assets)
dlCount += asset.download_count;
let buttonEl = createDownloadButton(
releaseJson[0].html_url,
window.location.pathname + "/releases",
formatNum(dlCount)
);
actionsEl.appendChild(buttonEl);
});
}

en | I am looking for something similar to `Promise.all` that will continue to resolve promises concurrently even in the event that one or more of the promises reject or throw an error. Each request does not rely on another request.
**Close to what I want - please see comments**
```
function fetchRequest (request) {
return new Promise(function (resolve, reject) {
fetch(request)
.then(function(response) {
return response.text();
}).then(function (responseXML) {
//Do something here. Maybe add data to dom
resolve(responseXML);
}).catch(function (err) {
reject(new Error(err));
}
}
function promiseRequests (requests) {
var result = Promise.resolve();
for (var i = 0; i < requests.length; i++) {
result = fetchRequest(requests[i])
}
//This is wrong as it will resolve when the last promise in the requests array resolves
// - not when all requests resolve
resolve(result);
}
promiseRequests(['url1.com', 'url2.com']).then(function (data) {
console.log('All requests finished');
//optionally have data be an array of resolved and rejected promises
});
```
I have succeeding in using `Promise.all` together with only ever resolving the fetchRequest promise and this results in the expected outcome (an array of results and `undefined`'s) but I feel like this is the wrong way to do things. It also removes my ability to use thrown errors.
**Works but feels like incorrect use of resolve**
```
function fetchRequest (request) {
return new Promise(function (resolve, reject) {
fetch(request)
.then(function(response) {
return response.text();
}).then(function (responseXML) {
resolve(responseXML);
}).catch(function (err) {
resolve();
}
}
Promise.all([fetchRequest('url1.com'), fetchRequest('url2.com')]).then(function (data) {
console.log('All requests finished', data); //data could be ['resultXML', undefined]
});
```

```
browser.urlbar.trimURLs
```
i.e., the above key is set to `false`

I'd like to see the full URL in the tooltip box there.
I see something like `http:/abs.../file.htm` notice the dots in the name. It shortened it. Even though the URL is not large and can fit in the window, it still trims it by putting these dots.

1st Attempt (My `pagerPosition` is giving error "pagerPosition cannot be resolved to a variable")
```
public void setWallpaper(){
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), pagerPosition);
try {
ImagePagerActivity.this.setWallpaper(bitmap);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Log.d("Gallery Example", "Image setted.");
}
```
2nd Attempt (My pagerPosition is giving error "pagerPosition cannot be resolved to a variable")
```
public void setWallpaper() {
try {
File file = new File("/sdcard/sampleimage");
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), pagerPosition);
bitmap.compress(CompressFormat.JPEG, 80, new FileOutputStream(file));
Context context = this.getBaseContext();
context.setWallpaper(bitmap);
Toast.makeText(getApplicationContext(), "Wallpaper has been set", Toast.LENGTH_SHORT).show();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.set_wallpaper:
setWallpaper();
return true;
default:
return false;
}
}
```
3rd Attempt (My setResource(R.id.pager) is not getting the image from the viewpager.
```
public void setWallpaper() {
WallpaperManager myWallpaperManager
= WallpaperManager.getInstance(getApplicationContext());
try {
myWallpaperManager.setResource(R.id.pager);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
```
Conclusion
If i put the below codes above my `onCreate` my whole project will not run.
```
Bundle bundle = getIntent().getExtras();
String[] imageUrls = bundle.getStringArray(Extra.IMAGES);
final int pagerPosition = bundle.getInt(Extra.IMAGE_POSITION, 0);

en | I am building a "Campground" site using Hibernate and Spring MVC. I have a "Campground" page that shows the details of a campground and user submitted comments. There is an "edit" button that can be used to edit the details of a `Comment`. This button sends you to a form (Spring form) where you can change the information and then the changes submitted are saved to the object then saved to the database using Hibernate.
Here is the issue. Somethings in the Hibernate Entity `Comment.java` are Objects retrieved from other tables in the database and Hibernate handles retrieving those objects using its Hibernate Magic. The problem is that these fields in the Entity class come back `null` when retrieved from the Spring `Model` (after submission of the form). This makes updating the object using a form a challenge. Fields like the `author` of type `User`, the `Campground` that it is associated with are all null. Is there a way to instruct Spring to not null out these fields when the results of the form are sent back? I found a way to avoid the id for the comment to not be nulled out using ` but it throws an exception when this is attempted on objects.
One solution I did come up with is to just update the `author` and `campground` field on the `Comment` object in my `@PostMapping` after the form is submitted, but that requires retrieving those objects from the database which seems redundant if there is a way to just not null them out in the first place. It feels like a band-aid when I may be overlooking a legitimate solution.
Below is the `Entity` classes in question along with the form to edit the `Comment`, and my Contoller.
`Comment Entity class`
```
@Entity
@Table(name = "comments")
public class Comment {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "id")
private Long id;
@Column(name = "text")
private String text;
@ManyToOne
@JoinColumn(name = "author")
private User author;
@ManyToOne
@JoinColumn(name = "campground")
private Campground campground;
public Comment() {
}
public Comment(String text, User author) {
this.text = text;
this.author = author;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public User getAuthor() {
return author;
}
public void setAuthor(User author) {
this.author = author;
}
public Campground getCampground() {
return campground;
}
public void setCampground(Campground campground) {
this.campground = campground;
}
@Override
public String toString() {
return "Comment{" +
"id=" + id +
", text='" + text + '\'' +
", author=" + author +
", campground=" + campground +
'}';
}
}
```
`@RequestMapping` from `Controller class`
```
@GetMapping("/campgrounds/{campgroundId}/comments/{commentId}/edit")
public String editComment(@PathVariable Long commentId, @PathVariable Long campgroundId, Model model, HttpSession session) {
User user = (User) session.getAttribute("user");
Comment comment = commentDAO.getComment(commentId);
if (!user.equals(comment.getAuthor())) {
return "redirect:/campgrounds/" + campgroundId;
}
model.addAttribute("editComment", comment);
return "editComment";
}
@PostMapping("/campgrounds/{campgroundId}/comments/{commentId}/edit")
public String editPostComment(@ModelAttribute("editComment") Comment comment,
@PathVariable Long campgroundId, @PathVariable Long commentId, HttpSession session) {
User author = (User) session.getAttribute("user");
comment.setAuthor(author); // because it comes back null
Campground campground = campgroundDAO.getCampgound(campgroundId);
comment.setCampground(campground); // because it comes back null
commentDAO.saveComment(comment);
return "redirect:/campgrounds/" + campgroundId;
}
```
Finally the `editComment.jsp`
```
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ include file="partials/header.jsp"%>
<div class="container mx-auto my-3">
<spring:form modelAttribute="editComment" action="${pageContext.request.contextPath}/campgrounds/${campgroundId}/comments/${commentId}/edit" method="post">
<div class="card border-info">
<h3 class="h3 text-center card-header badge-info">Edit Comment</h3>
<div class="my-3">
<spring:hidden path="id"/>
<div class="form-group col-5 m-auto">
<label for="comment_text">Comment Text</label>
<spring:textarea id="comment_text" path="text" cssClass="form-control"/>
</div>
<input class="btn btn-primary form-control mt-3" type="submit" value="Submit">
</div>
</div>
</spring:form>
</div>
<%@ include file="partials/footer.jsp"%>

en | In the C++ standard libraries I found only a floating point log method. Now I use log to find the level of an index in a binary tree ( `floor(2log(index))` ).
Code (C++):
```
int targetlevel = int(log(index)/log(2));
```
I am afraid that for some of the edge elements (the elements with value 2^n) log will return n-1.999999999999 instead of n.0. Is this fear correct? How can I modify my statement so that it always will return a correct answer? | ArmelR/stack-exchange-instruction | {
