30,336,337 | I'm a bit confused about the different between **Events** and **Listeners**.
I understood how you can create your events under `Events` then register them and implement the Handlers in `Handlers\Events`. So here I have events and the handling of events.
They work after I define them in `Providers\EventServiceProvider.php`
```
protected $listen = [
UserHasSignedUp::class => [
SendWelcomeEmail::class,
SendAdminEmail::class
]
];
```
So what are **Listeners**?
To me they seem exactly the same thing as **Event Handlers**? | 2015/05/19 | [

It's just the backward compatibility provided in Laravel 5.1. In other words, earlier, Jobs/Commands/Listeners were **not self-handling**, now **they are**.
**Note that**, `handler:event` is not available **after Laravel 5.1**. | There's not too much information on this out there, so this might just be speculation. I took a look at [this video](https://www.youtube.com/watch?v=WNYb1r4eMio) and saw that you can use handlers with commands. I think if you're using commands, that makes sense to have all your handlers in one spot. However if you're not, then having a `App\Handlers\Events\Whatever` might not be as desirable as `App\Listeners\Whatever`. |

**Note that**, `handler:event` is not available **after Laravel 5.1**. | Listeners vs. Handlers :
A listener `listen` for a specific event to be fired. xxxxCreatedListener will only listen for xxxx
A handler can handle multiple events to be fired. For exemple, let's say you use performing CRUD operations, your handler could wait for the xxxxCreatedEvent, xxxxDeletedEvent, xxxxUpdatedEvent. |

123,439 | Recently, I learned about the concept of the [51% attack](https://www.investopedia.com/terms/1/51-attack.asp) which a malicious actor could perform on a cryptocurrency. Essentially, if you can control >50% of the hashing power for a given cryptocurrency, you can control the blockchain which allows you to do all sorts of devious things like [double-spending](https://www.investopedia.com/terms/d/doublespending.asp) the cryptocurrency.
There's even a website, [crypto51.app](https://www.crypto51.app/), which keeps track of the theoretical costs of performing such an attack. This cost seems to come from the money one would spend in gaining that >50% control for an hour - usually in terms of renting computing time.
Clearly, the more computing power the cryptocurrency community is putting into mining, for a given cryptocurrency, the harder and more expensive it is to perform a 51% attack. So crypocurrencies like Bitcoin are reasonably safe from an attack like this. However, newer, less mined crypocurrencies are *much* more likely susceptible to the 51% attack.
So my question is, how can new cryptocurrencies even form? It seems like people are forming their own cryptocurrencies left and right, even as jokes (see , e.g., [dogecoin](https://dogecoin.com/)). How can new currencies get off the ground and gain enough critical mass to be reasonably safeguarded against a 51% attack? Why don't most new cryptocurrencies get killed off nearly immediately by an attack like this? | 2020/04/03 | [

] | Generally new cryptocurrencies are protected either by a complete lack of incentive to attack them, or by amassing support leading up to their eventual "launch." Older ones are somewhat protected by people being vigilant and communities occasionally agreeing on hard forks to ignore transactions on "compromised" chains; 51% attacks -- which don't actually need 51% of the network to pull off -- are still a threat even for well established blockchains.
Double spending relies on there being someone who wants the cryptocurrency you have that you can dupe, and the amounts being transacted being high enough to offset hardware costs, time investments, opportunity costs, or other costs related to the attack. Very new cryptocurrencies will typically have almost nobody to transact with in the first place; and will have a very low "market cap", which severely limits the returns. There is generally no financial incentive to attack a new blockchain.
There are some cyrptocurrenices that are "launched" with substantial support, where individuals creating the cryptocurrency will offer "ICOs" and other means of generating interest. While this would make for a much more lucrative target compared to another new crypto that has no such interest, it also means that the costs for the attack are much greater, and there will be more interest in forking away from "compromised" chains among the userbase.
Futher, successfully attacking a blockchain like this is relatively easy to detect, and will erode confidence or interest in a cryptocurrency, of which most new cryptos have little to spare. Even if your attack is not "reversed" by the majority with a fork, you will crater the value of any amount you gain through double spends. | Many cryptocurrencies are launched with the intent to fleece people by giving you money for worthless cryptocurrency. So all you need is a great launch and lots of initial sales. Since the intent was never for the victims / suckers to make any profit, who cares about a 51% attack? The people who launched the cryptocurrency got lots of money for worthless cryptocurrency, they don't care if others can use a 51% attack to steal more of that cryptocurrency. |

Regarding your issue:
if'd you use [RioFS](https://github.com/skoobe/riofs), you could mount a bucket and have a write access to it using the following command (assuming you have installed [RioFS](https://github.com/skoobe/riofs) and have exported AWSACCESSKEYID and AWSSECRETACCESSKEY environment variables):
```
riofs -o allow_other http://s3.amazonaws.com bucket_name /mnt/static.example.com

Please note that the project is still in the development, there are could be still a number of bugs left.
If you find that something doesn't work as expected: please fill a issue report on the [project's GitHub page](https://github.com/skoobe/riofs/issues?state=open).

3,856 | I've recently signed up for Google Apps because of the email support. I only use the web based gmail client for all my mail.

] | Google recently [announced](http://gmailblog.blogspot.com/2010/07/rich-text-signatures.html) support for rich text in signatures. That means you can now configure the font family, size and color, as well as insert images into the signature. Just go to your gmail settings and you'll find it right there, no need to enable as a lab feature or anything! It's possible it hasn't been expanded to Google Apps for your domain yet, in which case it should be coming pretty soon.

So if you also set up Gmail to automatically respond to the e-mail account the message was originally sent to it means you automatically get the correct signature on your reply. Very nice. |
682,123 | I have an OpenVPN client on a Windows 7, that connects to an OpenVPN server with tap.
The tunnel establishes correctly.
AFAIK, tap means that my virtual adapter is 'virtually' connected to the remote LAN, gets a remote LAN ip and participate in the LAN broadcast domani and so on.
When the tunnel is established, **my virtual adapter gets the correct IP.**
**But I cannot ping the other hosts in the remote network.**
It might be a problem on the sererver side, but before checking there i've noticed something strange on the client side, in the way Windows handles the virtual interface.
Let's begin.
When the tunnel is up, the virtual interface is up too. In my routing table i can see my phisical network 192.168.2.0, infact my local IP is 192.168.2.134.
Then I can see the remote network 172.16.1.0, directly attached to my interface 172.16.1.40. So far so good.
(i've removed loopback entries)
```
0.0.0.0 0.0.0.0 192.168.2.1 192.168.2.134 25
172.16.1.0 255.255.255.0 On-link 172.16.1.40 276
172.16.1.40 255.255.255.255 On-link 172.16.1.40 276
172.16.1.255 255.255.255.255 On-link 172.16.1.40 276
192.168.2.0 255.255.255.0 On-link 192.168.2.134 281
192.168.2.134 255.255.255.255 On-link 192.168.2.134 281
192.168.2.255 255.255.255.255 On-link 192.168.2.134 281
224.0.0.0 240.0.0.0 On-link 172.16.1.40 276
224.0.0.0 240.0.0.0 On-link 192.168.2.134 281
255.255.255.255 255.255.255.255 On-link 172.16.1.40 276
255.255.255.255 255.255.255.255 On-link 192.168.2.134 281
```
Thus, clients on the remote network shouldn't be reached via gateway, but through direct routing via the virtual interface provided by openvpn.
But
when i trace the route to an host on the remote network (that my PC should see as local) my client routes it on the gateway, and obviously, get lost.
```
C:\Users\agostinox>tracert 172.16.1.17
1 1 ms 1 ms 1 ms 192.168.2.1
2 14 ms 96 ms 101 ms 192.168.1.1
3 * * * Richiesta scaduta.
4 24 ms 12 ms 12 ms 172.17.129.137
5 * * * Richiesta scaduta.
```
And here it seems that the system routes packages **straight to the gateway** as it didn't see the directly attached network adapter.
Why does this happen?

] | Not being too Windows savvy wrt. OpenVPN, FWIW, here is my bid on what the culprit might be here:
* Looking at the output from your Windows route command, it seems you are missing a gateway entry for the OpenVPN network. True, you have an address on the VPN net (the 172.16.1.40 address), but no gw is defined for that net. On my box, I have access to several networks, each with its own GW like so:
```
0.0.0.0 0.0.0.0 172.20.68.2 172.20.69.3 20
10.0.3.0 255.255.255.0 172.20.68.5 172.20.69.3 21
```
To fix this, open your openvpn server config and add a line like this:
```
push "route 172.16.1.0 255.255.255.0"
```
to it. This ensures that a proper route is pushed to the client whenever the connection to the server is up.
* You may also be missing the return route - sometimes (not always for reasons I don't quite get) you need to add an `iroute` to the config entry you have for a given client in the server `ccd` directory (`/etc/openvpn/ccd/<vpn>/<client-id>`). This brings up the reverse route when a client connects to the server. the contents of one of my `ccd` files looks like this:
```
iroute 192.168.87.0 255.255.255.0
```
This ensures the OpenVPN server can correctly route stuff back to the client
* I think you can also just add `iroute`s to the main server config, but then they will be defined even if the client is not connected. That would look like this:
```
route 192.168.87.0 255.255.255.0 192.168.11.1
```
* **EDIT:** Also note that running OpenVPN clients on Windows requires administrative privileges. Otherwise, OpenVPN will not be able to add routes and such (as noted in the comments to your question). Best thing is to run it as a service so connections come up automatically on boot. At least, that works out really well in my scenarios.
I think that might get you going again. OpenVPN is really great and I have used it successfully for both business and gaming purposes for some time now :-) | I have a feeling you are not pushing your routes correctly from the server. I noticed that your gateway for the VPN is an IPv6 address.
Try using the `push` option in server.conf to push your routes. You might also want to add the `server` directive so you can reserve the client subnet.
If you're on linux you will need to have `net.ipv4.ip_forward = 1` on the VPN server set up with `sysctl` as well.

682,123 | I have an OpenVPN client on a Windows 7, that connects to an OpenVPN server with tap.
The tunnel establishes correctly.
AFAIK, tap means that my virtual adapter is 'virtually' connected to the remote LAN, gets a remote LAN ip and participate in the LAN broadcast domani and so on.
When the tunnel is established, **my virtual adapter gets the correct IP.**
**But I cannot ping the other hosts in the remote network.**
It might be a problem on the sererver side, but before checking there i've noticed something strange on the client side, in the way Windows handles the virtual interface.
Let's begin.
When the tunnel is up, the virtual interface is up too. In my routing table i can see my phisical network 192.168.2.0, infact my local IP is 192.168.2.134.
Then I can see the remote network 172.16.1.0, directly attached to my interface 172.16.1.40. So far so good.
(i've removed loopback entries)
```
0.0.0.0 0.0.0.0 192.168.2.1 192.168.2.134 25
172.16.1.0 255.255.255.0 On-link 172.16.1.40 276
172.16.1.40 255.255.255.255 On-link 172.16.1.40 276
172.16.1.255 255.255.255.255 On-link 172.16.1.40 276
192.168.2.0 255.255.255.0 On-link 192.168.2.134 281
192.168.2.134 255.255.255.255 On-link 192.168.2.134 281
192.168.2.255 255.255.255.255 On-link 192.168.2.134 281
224.0.0.0 240.0.0.0 On-link 172.16.1.40 276
224.0.0.0 240.0.0.0 On-link 192.168.2.134 281
255.255.255.255 255.255.255.255 On-link 172.16.1.40 276
255.255.255.255 255.255.255.255 On-link 192.168.2.134 281
```
Thus, clients on the remote network shouldn't be reached via gateway, but through direct routing via the virtual interface provided by openvpn.
But
when i trace the route to an host on the remote network (that my PC should see as local) my client routes it on the gateway, and obviously, get lost.
```
C:\Users\agostinox>tracert 172.16.1.17
1 1 ms 1 ms 1 ms 192.168.2.1
2 14 ms 96 ms 101 ms 192.168.1.1
3 * * * Richiesta scaduta.
4 24 ms 12 ms 12 ms 172.17.129.137
5 * * * Richiesta scaduta.
```
And here it seems that the system routes packages **straight to the gateway** as it didn't see the directly attached network adapter.
Why does this happen?

* Provide links to your file as (for example) <http://example.com/trackedDownloader.php?id=someUniqueIdentifer>

] | You're basically asking how to apply different transformations to an array depending on the index of the specific item. With Ruby you can chain `with_index` onto enumerators and then use the index inside your enumerator block as you loop through each array item. In order to transform an array into a new one, you will need to use `map`.
```
transformed_tests = tests.map.with_index do |test, index|
if index.even?
test.upcase
else
test.downcase
end
end
```
or, a more compact version:
```
transformed_tests = tests.map.with_index do |test, index|
test.send(index.even? ? :upcase : :downcase)
end
```
If you want to make the transform whilst collecting the input:
```
tests = 5.times.map do |index|
input = gets.chomp
input.send index.even? ? :upcase : :downcase
end
``` | You want a simple way?
```
n = 5
test = []
(n/2).times.with_object([]) do
test << gets.chomp.upcase
test << gets.chomp
end
test << gets.chomp.upcase if n.even?
```
More Rubylike:
```
n.times.with_object([]) do |i,test|
str = gets.chomp
str.upcase! if i.odd?
test << str
end

] | Unfortunately, there is no way to enforce that only objects (singletons in Kotlin) can inherit from a certain abstract/open class or interface in Kotlin. `object` declaration is just syntactic sugar for a regular class with a Singleton pattern.
I know it's not much, but I guess you can achieve this to a certain degree by adding documentation, asking users to implement this class by Singletons alone.
By the way, I would use an interface instead of an abstract class for this purpose. | Instead of creating abstract class just change the code like this:-
```
object SingletonConnection{
fun start(){ /* code */ }
fun connect(){ /* code */ }
fun clientLogic()

It will provide the same implementation which you want to achieve using abstract class.
Also get the method using this code:-
```
SingletonConnection.start()

] | The `Users` tab is only shown because there is a `Members` folder (with the title `Users`) in the root that is publicly visibile.
You have three options to deal with the default; make the `Members` folder private, delete it altogether, or remove the `index_html` default view.
Unpublish
---------
You can 'unpublish', retract, the folder workflow to make it private, and anonymous users are then redirected to the login form instead of seeing the user search form:
Simply go to the folder, click on the workflow state (`Published`) and choose `Retract`.
Delete
------
If you do not need to have per-user folders, you can remove the `Members` folder altogether. You do need to make sure that user folder creation is not enabled first. Go to the Control Panel (click on your username, top right, select `Site Setup`):
select `Security`:
and make sure that `Enable User Folders` is not checked. If it is, uncheck it and save the settings.
Now just delete the `Members` folder; click `Users`, find the `Actions` menu on the right, then select `Delete`:
then confirm the deletion in the popup:
Deletion means *all* users will get a 404 when visiting `/Members` in your site.
Delete the default view
-----------------------
The `Members` folder contains a `index_html` object that provides the user form search. If all you want to get rid of is this view, you can delete it. If your `Members` folder is still public, visitors *can* see any userfolders that have been created though.
Deleting this view requires going to the ZMI, the Zope Management Interface, navigating to the `Members` folder and deleting the `index_html` object there.
Since this is not really the recommended course of action I'm leaving out the screenshots for this part. | You can just delete the Users folder. |

] | AFAIK, you can't create a `File` from an assets file because these are stored in the apk, that means there is no path to an assets folder.
But, you can try to create that `File` using a buffer and the [`AssetManager`](http://developer.android.com/reference/android/content/res/AssetManager.html) (it provides access to an application's raw asset files).
Try to do something like:
```java
AssetManager am = getAssets();
InputStream inputStream = am.open("myfoldername/myfilename");
File file = createFileFromInputStream(inputStream);
private File createFileFromInputStream(InputStream inputStream) {
try{
File f = new File(my_file_name);
OutputStream outputStream = new FileOutputStream(f);
byte buffer[] = new byte[1024];
int length = 0;
while((length=inputStream.read(buffer)) > 0) {
outputStream.write(buffer,0,length);
}
outputStream.close();
inputStream.close();
return f;
}catch (IOException e) {
//Logging exception
}
return null;
}
```
Let me know about your progress. | Unless you unpack them, assets remain inside the apk. Accordingly, there isn't a path you can feed into a File. The path you've given in your question will work with/in a WebView, but I think that's a special case for WebView.
You'll need to unpack the file or use it directly.
If you have a Context, you can use `context.getAssets().open("myfoldername/myfilename");` to open an InputStream on the file. With the InputStream you can use it directly, or write it out somewhere (after which you can use it with File). |

compile project(':')

However, it is rarely a good idea to do this. It is too easy to end up with circular dependencies.

compile project(":")
}
//Without this, my subproject's tests would not compile or run

47,636,430 | I'm struggling to setup nginx inside a docker container. I basically have two containers:
* a php:7-apache container that serves a dynamic website, including its static contents.
* a nginx container, with a volume mounted inside it as a **/home/www-data/static-content** folder (I do this in my docker-compose.yml), to try to serve a static website (unrelated to the one served by the apache container).
I want to use the domain **dynamic.localhost** to serve my dynamic website, and **static.localhost** to serve my static website only made up of static files.
I have the following Dockerfile for my nginx container:
```
########## BASE #########
FROM nginx:stable
########## CONFIGURATION ##########
ARG DEBIAN_FRONTEND=noninteractive
ENV user www-data
COPY ./nginx.conf /etc/nginx/nginx.conf
COPY ./site.conf /etc/nginx/conf.d/default.conf
RUN touch /var/run/nginx.pid && \
chown -R ${user}:${user} /var/run/nginx.pid && \
chown -R www-data:www-data /var/cache/nginx
RUN chown -R ${user} /home/${user}/ && \
chgrp -R ${user} /home/${user}/
USER ${user}
```
As you see I'm using two configuration files for nginx: nginx.conf and site.conf.
Here is nginx.conf (it's not important because there is nothing special in it but if I'm doing something wrong just let me know):
```
worker_processes auto;
error_log /var/log/nginx/error.log debug;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
keepalive_timeout 65;
include /etc/nginx/conf.d/*.conf;
}
```
And here is the file site.conf that I have been failing miserably at writing correctly for days now:
```
server {
listen 8080;
server_name static.localhost;
root /home/www-data/static-content;
location / {
try_files $uri =404;
}
}
server {
listen 8080;
server_name dynamic.localhost;
location / {
proxy_pass http://dynamic;
proxy_redirect off;
proxy_set_header Host $host:8080;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Port 8080;
proxy_set_header X-Forwarded-Host $host:8080;
}
}
```
(<http://dynamic> passes the request to the apache container that I name "dynamic").
So basically I keep getting 404 for whatever file I try to access in my static-content directory. E.g.:
* static.localhost:8080/index.html should serve /home/www-data/static-content/index.html but I get 404 instead.
* static.localhost:8080/css/style.css should serve /home/www-data/static-content/css/style.css but I get 404 too.
I tried various things, like writing *try\_files /home/www-data/static-content/$uri*, but I didn't get any result. I read some parts of nginx documentation and searched on Stack Overflow but nothing that I found helped me. If I made a stupid mistake I apologize, but the only thing that I care about now is to get this to work, and to understand what I'm doing wrong.

] | It looks like you'd do well to take advantage of ImageMagick's "-gravity" setting here. This might not be exactly what you're looking for, but notice how "-gravity" works to locate the overlay image with "-composite", and the text is located with "-annotate" using a command like this...
```
convert foo.png -resize 572x572 \
-size 612x792 xc:white +swap -gravity center -composite \
-gravity north -pointsize 24 -annotate +0+100 "Title Text" laid-out.png
```
That starts by reading in "foo.png" and resizing it. Then it sets the size of the desired canvas, creates a white canvas of that size, sets the gravity to center, swaps the overlay image with the canvas to get them in the correct order, and composites "foo.png" centered on the canvas.
Then it changes the gravity setting to north, sets the pointsize of the text, and annotates the image with the text located "+0+100". That's zero pixels from center left to right, and 100 pixels down from the top.
A couple experiments should help you find settings to suit your need. | Here is an alternate way to do it in ImageMagick using montage.

montage -title "Testing" logo.jpg -geometry 160x120+25+25 -tile 1x1 -frame 0 -background white logo_title.jpg
```
[](https://i.stack.imgur.com/5Fboi.jpg)
The geometry argument 160x120 resizes to that dimension and the +25+25 adds a border of that size. Note that this gives somewhat less flexibility in positioning the title than GeeMack's solution. |

You would still need a server in order for individual users to discover each other but then they could connect directly to each other rather than having to pass all their traffic via a central server. | The idea.
You can use a simple **echo server** written in any language. Your script can send the data to the server then get it back, handle it on the same page with different functions/classes emulating the real server.
An example: <http://www.websocket.org/echo.html>
Then, you can think about different formats of packets to/from server to diffirentiate them inside one script. |

* Spawned Mirmulnir
* Turned the overgrown lizard into charred meat
And STILL I'm not absorbing its soul!
UPDATE 2: Verifying the game cache integrity turned up 3 corrupted files. Wish I knew which those were, but I had cleaned my master files using TES5Edit, so I thought I had screwed up something there. Created a new barebones game, and at last, I'm having some dragon spirit chow. Then, created a new fully modded game, and no soul chow for me... For a moment I wanted to pin the blame on TES5Edit but now I know that's not the cause. The culprit's still at large.
UPDATE 3: After having no luck with a fully modded game, started to gradually activate mods again... eventually I realized that the truckload of mods I had activated on my previous attempt broke something **again** on my vanilla installation, for even another barebones try was plagued with this issue.

UPDATE 5: *Probably* ModOrganizer has something to do with this. However insane it sounds.

Yes, scripts are baked into saves. However, there is a way to remove scripts left by uninstalled mods in savefiles. You need to configure [Skyrim Script Extender (SKSE)](http://skse.silverlock.org/) to use its `ClearInvalidRegistrations` console command. It removes invalid scripts left running by uninstalled mods. This feature was introduced in [v1.6.7 of SKSE](http://skse.silverlock.org/skse_whatsnew.txt):

After configuring SKSE to use the `ClearInvalidRegistrations` command, try uninstalling the 'No Spinning Death' mod and then see if the issue is fixed. Otherwise, you'll have to disable half your mods and then test again. Rinse and repeat until you find the offending mod. | If that is your load order I see one problem: You have the skyrim patch after the DLC patches - it needs to go first.

138,924 | Anyone around coy with being Mr. Fixit? (Ms. Fixit would be even better, but either will do nicely.) I can't absorb dragon souls, and yes, I've been through almost every thread there is here on the answer. (So please, do not duplicate me. Pretty please?)
Mind you, I got a *TRUCKLOAD* of mods installed... *(ducks in preparation for the coming brick)* Odd thing is, I was playing with a very similar list before installing Dragon Combat Overhaul and Succubus Race, but deactivating either won't get me anywhere.
Done some digging on the Nexus and Steam forums... I read somewhere that No Spinning Death overwrites a script related to dragon death. It *might* be mucking up things some, but I can't tell. Disabling that mod didn't get me anywhere, but scripts are baked into saves (right?), so in theory I have to *(cringes)* restart the game to be absolutely sure...
Other bits worth (?) knowing:
* Running SKSE
* Running ENB
* Using ModOrganizer
UPDATE: There is something seriously broken with my game itself. Tried the following:
* Disabled ALL the mods, save for Alternate Start for quicker starts (and yes, this includes USKP, UDGP and UDBP)
* Started a new game, created a vanilla Nord character
* Toggled godmode on
* Given the PC Lightning Storm
* Spawned Mirmulnir
* Turned the overgrown lizard into charred meat
And STILL I'm not absorbing its soul!
UPDATE 2: Verifying the game cache integrity turned up 3 corrupted files. Wish I knew which those were, but I had cleaned my master files using TES5Edit, so I thought I had screwed up something there. Created a new barebones game, and at last, I'm having some dragon spirit chow. Then, created a new fully modded game, and no soul chow for me... For a moment I wanted to pin the blame on TES5Edit but now I know that's not the cause. The culprit's still at large.
UPDATE 3: After having no luck with a fully modded game, started to gradually activate mods again... eventually I realized that the truckload of mods I had activated on my previous attempt broke something **again** on my vanilla installation, for even another barebones try was plagued with this issue. Re-check integrity, and bam, another file -a very small one, not even 1k in size- was corrupted. (Again, I wish there was a way to know which!)
UPDATE 4: Tried a new game with just these on:
* USKP
* UDGP
* UDBP
* Alternate Start
Guess what. AGAIN the corrupted file issue.
Tried again with only Alternate Start active, and still cannot absorb dragon souls. Even while today I could on a similar setup. (I don't understand anything anymore here...) Anyone knows of a way to skip the intro without installing this mod?
(Could it be that ModOrganizer is somehow mucking things up?)
UPDATE 5: *Probably* ModOrganizer has something to do with this. However insane it sounds. Instead of manually disabling ESPs, I right-clicked on the mod list, selected 'Disable all visible mods', manually re-activated Alternate Start, and *this time* I could dine on dragon essence. Read again: a near-completely barebones setup, without even the unofficial patches.
UPDATE 6: Disregard what I said about MO screwing up things. One of the unofficial patches is misbehaving. Even with a truckload of mods on, I can still eat dragonstuff--right until activating all three of them. Which one is to blame I don't yet know.
**UPDATE 7 AND FINAL:** Finally, finally figured what's going on.

The patches should be interleaved with the actual DLC. | I had the same issue. However when I disabled all the unofficial patches I was still having this problem. I ended up taking the script extender off and it worked. Then slowly started uploading my mods back on that didn't need the script extender. I wanna put it back on there so I can have my immersion mods back that made the game more pretty but idk. We will have to wait and see. |

Yes, scripts are baked into saves. However, there is a way to remove scripts left by uninstalled mods in savefiles. You need to configure [Skyrim Script Extender (SKSE)](http://skse.silverlock.org/) to use its `ClearInvalidRegistrations` console command. It removes invalid scripts left running by uninstalled mods.

] | USKP has a problem with the dragonactorscript.pex file.
Found and installed a fix available here: <http://www.nexusmods.com/skyrim/mods/31685>
Personally, I went and overwrote the file from USKP itself instead of treating this fix as a separate mod, keeping a backup available just in case. | I had the same issue. However when I disabled all the unofficial patches I was still having this problem. I ended up taking the script extender off and it worked. Then slowly started uploading my mods back on that didn't need the script extender. I wanna put it back on there so I can have my immersion mods back that made the game more pretty but idk. We will have to wait and see. |
138,924 | Anyone around coy with being Mr. Fixit? (Ms. Fixit would be even better, but either will do nicely.) I can't absorb dragon souls, and yes, I've been through almost every thread there is here on the answer. (So please, do not duplicate me. Pretty please?)
Mind you, I got a *TRUCKLOAD* of mods installed... *(ducks in preparation for the coming brick)* Odd thing is, I was playing with a very similar list before installing Dragon Combat Overhaul and Succubus Race, but deactivating either won't get me anywhere.
Done some digging on the Nexus and Steam forums... I read somewhere that No Spinning Death overwrites a script related to dragon death. It *might* be mucking up things some, but I can't tell. Disabling that mod didn't get me anywhere, but scripts are baked into saves (right?), so in theory I have to *(cringes)* restart the game to be absolutely sure...
Other bits worth (?) knowing:
* Running SKSE
* Running ENB
* Using ModOrganizer
UPDATE: There is something seriously broken with my game itself. Tried the following:
* Disabled ALL the mods, save for Alternate Start for quicker starts (and yes, this includes USKP, UDGP and UDBP)
* Started a new game, created a vanilla Nord character
* Toggled godmode on
* Given the PC Lightning Storm
* Spawned Mirmulnir
* Turned the overgrown lizard into charred meat
And STILL I'm not absorbing its soul!
UPDATE 2: Verifying the game cache integrity turned up 3 corrupted files. Wish I knew which those were, but I had cleaned my master files using TES5Edit, so I thought I had screwed up something there. Created a new barebones game, and at last, I'm having some dragon spirit chow. Then, created a new fully modded game, and no soul chow for me... For a moment I wanted to pin the blame on TES5Edit but now I know that's not the cause. The culprit's still at large.
UPDATE 3: After having no luck with a fully modded game, started to gradually activate mods again... eventually I realized that the truckload of mods I had activated on my previous attempt broke something **again** on my vanilla installation, for even another barebones try was plagued with this issue. Re-check integrity, and bam, another file -a very small one, not even 1k in size- was corrupted. (Again, I wish there was a way to know which!)
UPDATE 4: Tried a new game with just these on:
* USKP
* UDGP
* UDBP
* Alternate Start
Guess what. AGAIN the corrupted file issue.
Tried again with only Alternate Start active, and still cannot absorb dragon souls. Even while today I could on a similar setup. (I don't understand anything anymore here...) Anyone knows of a way to skip the intro without installing this mod?
(Could it be that ModOrganizer is somehow mucking things up?)
UPDATE 5: *Probably* ModOrganizer has something to do with this. However insane it sounds. Instead of manually disabling ESPs, I right-clicked on the mod list, selected 'Disable all visible mods', manually re-activated Alternate Start, and *this time* I could dine on dragon essence. Read again: a near-completely barebones setup, without even the unofficial patches.
UPDATE 6: Disregard what I said about MO screwing up things. One of the unofficial patches is misbehaving. Even with a truckload of mods on, I can still eat dragonstuff--right until activating all three of them. Which one is to blame I don't yet know.
**UPDATE 7 AND FINAL:** Finally, finally figured what's going on.

58,197,804 | I have recently started using Ant Deisgn and really enjoyed working with it.
However I seem to have stumble upon an issue that I am having a hard time solving.
Using react-testing-library for tests, I am having troubles with testing some Ant Design component.
One of the reason is that for some unknown reason some components (e.g. Menu, Menu.Item, Dropdown, etc) do not render the custom attribute `data-testid` thus making impossible to target a specific element of the DOM.
This makes the tests less performant and accurate.
Did some else stumble upon the same issue ?
How did you go about solving this ?
Is there something that can be done by the Ant Design team about this issue ? | 2019/10/02 | [

] | The `data-testid` attribute is configurable to whatever attribute you want.
<https://testing-library.com/docs/dom-testing-library/api-configuration>
Also, as long as the library you choose, has ID attribute, you çan do following :
```js
const {container} = render(<Foo />) ;
const button = container.querySelector('#idValue'); // returns react element
fireEvent.click(button);
```
P. S: mobile edit. Pls ignore formats | Today, I had the same issue with testing a label of an Ant Design Desciptions.Item with the react-testing-library.
I figured out that the label was in a `<span>` element, so I moved it into a `<div>` element which solved my problem.
Before:
```
<Descriptions.Item
data-testid='test-label-of-descriptions-item-failed'
label={'some label'}
labelStyle={{ ...FONT_SMALL }}
contentStyle={{ ...FONT_SMALL }}
style={{ ...DESC_ITEM }}>
```
After:
```
<Descriptions.Item
label={ <div style={{ display: 'inline-block' }} data-testid='test-label-of-descriptions-item-worked' >'some label' </div> }
labelStyle={{ ...FONT_SMALL }}
contentStyle={{ ...FONT_SMALL }}

[Next.js has its own routing mechanism](https://nextjs.org/docs/basic-features/pages) which is used for both client-side routing and server-side routing.
By using React Router, you're bypassing that with your own client-side routing so when you request the page directly (and depend on server-side routing) you get a 404 Not Found.

69,113,035 | I have the following data:
```
data_list = ["\"TOTO TITI TATA,TAGADA\"", "\"\"\"TUTU,ROOT\"\"\""]
```
It is transformed into a pandas dataframe:
```
df = pandas.DataFrame(data_list)
print(df)
0
0 "TOTO TITI TATA,TAGADA"
1 """TUTU,ROOT""
```
When writing the dataframe as a csv, without any quoting configuration, I get the following result:
```
with open("test_quote_normal", "w") as w:
df.to_csv(w, index=False, header=False)
```
-> result output
```
"""TOTO TITI TATA,TAGADA"""
"""""""TUTU,ROOT"""""""
```
Every quotes have been quoted, which is not something I want.
So i tried to prevent this with the following configuration:
```
with open("test_quote_none", "w") as w:
df.to_csv(w, index=False, header=False,
quoting=csv.QUOTE_NONE, escapechar=',')
```
-> result output
```
"TOTO TITI TATA,,TAGADA"
"""TUTU,,ROOT"""
```
The quotes are correct, but for a reason I do not understand, the escape char has been inserted in the data itself.
Specifying the sep value has no effect:
```
with open("test_quote_none", "w") as w:
df.to_csv(w, index=False, header=False,
quoting=csv.QUOTE_NONE, escapechar=',', sep= ",")

] | `"` and `,` are both special characters by default in csv format
`"` is used when `,` is there between a data. That time the data is escaped by quotes to tell that it should be a single data.
whereas, `,` is the default seperator for distinguishing between data.
Since you are using both of them in your data, that's why you are having such a hard time debugging it
**First snippet**
```
with open("test_quote_normal", "w") as w:
df.to_csv(w, index=False, header=False)
```
If the data still has `"`, as per csv conventions, it should also be escaped which was causing multiple `"` in your first scenario
**Second snippet**
```
with open("test_quote_none", "w") as w:
df.to_csv(w, index=False, header=False,
quoting=csv.QUOTE_NONE, escapechar=',')
```
Using the `quoting` parameter, you are telling that you don't indent quotes to protect the `,` character. So the `,` inside your data is being treated as a separator causing the escape character to come between them
For more clarity, you can see the output of these snippets
```
with open("temp.csv", "w") as w:
...: df.to_csv(w, index=False, header=False, quotechar='@')
```
Output
```
@"TOTO TITI TATA,TAGADA"@
@"""TUTU,ROOT"""@
```
In this, we are changing the `quotechar` to become `@`, that's why, instead of using `"` for protecting `,`, this time `@` is being used to escape data with `,` inside them
```
with open("temp.csv", "w") as w:
...: df.to_csv(w, index=False, header=False, escapechar='@', doublequote=False)
```
Output
```
"@"TOTO TITI TATA,TAGADA@""
"@"@"@"TUTU,ROOT@"@"@""
```
In this, the quotechar is still the same, but for escaping them, we are changing it to `@` for clarity, this time you can see the difference on `quotechar` and `escapechar`
I hope this helps your question | Is it what you expect?
```
print(df.to_csv(index=False, header=False, quoting=csv.QUOTE_NONE, sep= "@"))

] | Get rid of your `height: 100%` declarations. It seems like setting the height to 100% just sets it to 100% of the viewport, not actually 100% of the page itself. | Here's an expansion of my comment to use SVG instead of vendor prefix and proprietary extensions. This reduces the size of the CSS and, with the employment of some ingenius tactics, can allow you to use a single SVG file as a sprite pack for gradients (reducing the total number of HTTP requests).
First create your SVG file and gradient (per your question specs):
```
<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="1" height="500" version="1.1" xmlns="http://www.w3.org/2000/svg">
<g>
<defs>
<linearGradient id="ui-bg-grad" x1="0%" x2="0%" y1="0%" y2="100%">
<stop offset="0%" stop-color="#afb1b4" />
<stop offset="100%" stop-color="#696a6d" />
</linearGradient>
</defs>
<rect fill="url(#ui-bg-grad)" x="0" y="0" width="100%" height="500"/>
</g>
</svg>
```
Next, here's your new declaration:
```
html {
height: 100%;
}
body {
height: 100%;
margin: 0;
padding: 0;
background-repeat: no-repeat;
background-color: #afb1b4; /* Old browsers: anything not listed below */
background-image: url("grad.svg"); /** Browsers that support SVG: IE9+, FF4+, Safari 4+(maybe 5), Opera 10+
}
```
Now, if you want to support older browsers with png image, you can with one little change. Since any property that uses `url()` does not support hinting (like `@font-face`'s `src` property), you have to alter the rule a little.
```
html {
height: 100%;
}
body {
height: 100%;
margin: 0;
padding: 0;
background-repeat: no-repeat;
background-color: #afb1b4; /* Image fails to load, or FF3.5 */
background-image: url("grad.png"); /* Old browsers: anything not listed below or above */
}
body:not(foo) { /* most browsers that support :not() support SVG in url(), except FF3.5 */
background-image: url("grad.svg"); /* Browsers that support SVG: IE9+, FF4+, Safari 4+(maybe 5), Opera 10+ */
}
```
If you want to get stupid crazy, you could base64encode the SVG file so that you don't have to download another file from the server then add it as a class to be reused (prevent repasting the base64 in multiple place).
```
.svg-sprite:not(foo)

I don't know what you are cooking with this, but to me, this is a huge cannon shooting towards the DB. Try to optimize your queries into a single one. Don't ever imagine DB fetches with a loop in your mind. | It looks like every element of `$followers` is a value returned from `mysql_fetch_assoc()`. Each element will be an associative array, and when you echo it I would expect to see it echoed as the string `'Array'`, since that is PHP's usual behaviour.
One point to observe is that when you create an empty array using `array()` and then populate it using assignments of the form `$myarray[] = ...`, the resulting array will be zero-indexed. That is, the keys of the array will start at 0, not at 1. So instead of `for ($a = 1; $a <= $numberOfFollowers; $a++) {`, you need to use `for ($a = 0; $a < $numberOfFollowers; $a++) {`, or go for the solution suggested by @Shef and use `foreach`.
Your problem might arise because `$followers` contains only one element, and because of the off-by-one error, you are not seeing any output. Turn on error reporting by adding this line at the start of your script:
```
error_reporting(E_ALL & ~E_STRICT);
```
If I am right then with your current code, you should see a `Notice: Undefined index: 1 ...` |

I'm trying to extract just the code that will allow me to decode images encoded in the WSQ image format.

which is contradicted by a grep search, as well as complaints of undefined functions which are indeed defined in a single C file in each case.
I looked at the include files and these functions do have the word extern before them in the declarations.
As for the error messages of "multiple definitions" the linker says "first defined here" and only gives one object file in each case.
All C files have a C extension.

While the answer by @Ossir works properly, I have found one library called [cocoapods-deintegrate](https://github.com/kylef/cocoapods-deintegrate) that takes charge of all the work that deintegrate CocoaPods from your project.
In order to use it, you first install it by `gem install cocoapods-deintegrate` (*sudo* might be required) and then just `pod deintegrate` from your project root. It still leaves *Podfile*, *Podfile.lock*, and *.xcworkspace/*. |
206,579 | Bits Back coding is a scheme to transmit an observation $x$.
You can read about it [here](http://www.cs.toronto.edu/~fritz/absps/freybitsback.pdf)[1]. To my understanding, it works like this:
1. The encoder samples a message $z$ from a distribution $Q(z|x)$ that it computed.
2. The encoder sends $z$ to decoder, using a code based on $P(z)$, known to both.
3. The decoder recovers $z$ and computes $P(x|z)$.
4. The encoder sends $x$ to the decoder using a code based on $P(x|z)$.
5. The decoder recovers $x$.
In reality, the messages in steps 2 and 4 can be combined. Naively, the cost of this protocol would be the expected number of bits in these messages.
However, the trick is that once the decoder recovered $x$, it can compute $Q(z|x)$ using the same algorithm the encoder used, and then recover all the auxiliary bits it had to use internally in order to sample $z$ from $Q$. The expected number of these bits is then subtracted from the total cost. Those are "the bits you get back".
What I don't understand is what is the decoder going to do with these bits? How does knowing these bits reduces the overall transmission cost? Yes, the decoder is now aware of some bits that the encoder withdrew from a random-stream of bits, but how is this knowledge going to help in compressing the next observations?

] | I was wondering the same! But this is the answer I came up with (although I am not entirely sure if this reasoning is correct).
Since after the decoding process the decoder knows the distribution $Q(z|x)$ AND $P(x)$, he could then come up with an encoding that follows the distribution $P(z)/Q(z|x)$ and thus, represents each sample value $z$ with $-log\_2(P(z)/Q(z|x))$ bits. Apparently, this representation of the sample values (and thus, of the model) would lead to maximal compression of the data values if the approximate variational posterior equals the actual posterior, thus $Q(z|x) = P(z|x)$. | I think that the key to understand bits-back coding is that sampling from the distribution $Q(z|x)$ is equal to decoding some "random bits" with $Q(z|x)$. And these random bits are the things that receiver can get automatically after receiving $z$ and $x$.
Considering a sequential image transmission scenario, if we use the encoding results of previous image as the random seed for current image to sample from the $Q(z|x)$ in the sender part, these bits can then be subtracted from the total cost.
By the way, if the "random bits" used for sampling is not truly random there will be negative effects on your bits-back coding scheme. |

Furthermore, you should always implement unit tests for every piece of functionality.
If you have questions about case sensitivity, implement unit tests to prove your assumptions right. | Let's look at how cases are defined in the standards for EXPRESS (used to specify the schema) and for STEP physical files (used for the actual \*.ifc files).
### Entity type names in the schema definition
According to [ISO10303-11](https://www.iso.org/standard/38047.html), in EXPRESS, entity names are case-insensitive. The grammar only mentions lower-case letters for entity identifiers (section 7.4 Identifiers and 7.1.2 Letters), reserving upper case for *EXPRESS* reserved words such as `ENTITY`.
```
entity_head = ENTITY entity_id subsuper ";" .
entity_id = simple_id .
simple_id = letter { letter | digit | '_' }
letter = 'a' | 'b' | 'c' | ... | 'x' | 'y' | 'z'
```
So a schema can not define two different entity types that differ only by their case. In addition, the standard explicitly states case insensitivity:
>
> *EXPRESS* uses the upper and lower case letters of the English alphabet [..] The case of letters is significant only within explicit string literals.
> NOTE - *EXPRESS* may be written using upper, lower, or mixed case letters [..].
>
>
>
Thus, the camel case you see in IFC-EXPRESS definitions (e.g. for [IFC4](http://www.buildingsmart-tech.org/ifc/IFC4/Add2TC1/IFC4.exp)) and in the corresponding BuildingSMART [documentation](http://www.buildingsmart-tech.org/ifc/IFC4/Add2TC1/html/link/alphabeticalorder-entities.htm) is not significant and just chosen for the sake of readability.
### Entity type names in the instance encoding
When it comes to the STEP physical file encoding ([ISO10303-21](https://www.iso.org/standard/63141.html)) and your actual instance files, the grammar mentions only upper case characters for entity types:
```
SIMPLE_ENTITY_INSTANCE = ENTITY_INSTANCE_NAME "=" SIMPLE_RECORD ";" .
SIMPLE_RECORD = KEYWORD "(" [ PARAMETER_LIST ] ")" .
KEYWORD = USER_DEFINED_KEYWORD | STANDARD_KEYWORD .
STANDARD_KEYWORD = UPPER { UPPER | DIGIT } .
UPPER = "A" | "B" | "C" | .. | "X" | "Y" | "Z" | "_" .
```
ISO10303-21 specifies further how to map the schema definition to the actual IFC file (section 12.2.). With regard to the encoding of entity type names it states that STEP files should only use upper case characters.
>
> [..] In either case, any small letters shall be converted to their
> corresponding capital letters, i.e., the encoding shall not contain
> any small letters.
>
>
>
This also ensures case insensitivity, but in a different way than in EXPRESS.
### Case sensitivity in STEP parsers
Coming back to the original question, whether `IFCPERSON` can be replaced with `IfcPerson`. If you where to write the standard, you could use any case you like, since entity type names are case insensitive.
```
ENTITY IfcPerson;
```
If you are writing an IFC-STEP file, a strict interpretation of the standard would require to write entity type names in upper case.
```
#1 = IFCPERSON('ID', 'Last', 'First', $, $, $, $, $));
```
In practice, parsers have to rely on the case-insensitivity of the schema anyway. Thus, they will perform case-insensitive comparison to the schema-defined entity type names. Most likely they will accept mixed- or lower-case entity type names in the \*.ifc file.
But a parser could also reject an IFC file with mixed-case entity type names as not standard-conforming or just ignore the entities which are not all-capital. Imagine an implementation that just converts the schema definitions to upper-case and then does a case-sensitive lookup for the entity instance types. This would be perfectly in accordance with the standard. |
41,535,837 | I want to build a website that allows the user to convert `Hz` to `bpm` (note however that my question concerns all sort of unit conversion). I am using PHP and am hosting my website on Apache.

If the user then adds a "0" so `120 bpm` will be automaticly and immediately converted to `2 Hz`.

] | Simpliest way: administrator credentials should be predefined via some config file on server side. As additional protection you may force user to change password on first log in. Another way: a lot of CMS provides a full access + installation steps to first loggined user. | Use QSslSocket to get a secured communication layer (<http://doc.qt.io/qt-5/qsslsocket.html>), since you will exchange passwords on top of this administration link.
There is an example here of the client part of the code, with Qt5: <http://doc.qt.io/qt-5/qtnetwork-securesocketclient-example.html>
On the server side, accept the socket on a predefined unused port, dedicated to your service.
Now, you can simply decide of a login with a random secret password, that will correspond to the administrator account, and create a program to send this password on top of a secured channel based on QSslSocket. You server has to check the password before accepting remote management.
So, as you can see, the administrator must be created prior to using the service. You can use a private mail exchange, based on some cryptographic means (OpenPGP, S/MIME, etc.), to supply the administrator with its password. |

Notice that for parallel projection (like here) box edges **do not seem to be parallel but they are** and for default *Mathematica* display they **are not but they look parallel** | I think the only way to do this is by dynamically reseting the [`ViewMatrix`](http://reference.wolfram.com/mathematica/ref/ViewMatrix.html) to be an [orthographic projection](http://reference.wolfram.com/mathematica/ref/ViewMatrix.html#464375084). It was beyond my ability, patience, or inclination to figure how to decompose the `ViewMatrix` that is created when the graphic is moved into the components `ViewPoint`, `ViewVertical`, etc. It seemed to me that the front end usually make a discontinuous jump from the view point in the orthographic projection to the initial view point in rotated graphic. Discouraged by this apparent behavior, I opted for a hybrid solution.
I used an ordinary `Graphics3D` with `Dynamic` view properties and used `Inset` to insert the graphics `tom2` into it. The view properties of the outer `Graphics3D` are used to compute a corresponding orthographic projection `ViewMatrix` to be used to display the graphics `tom2`. So the mouse rotates the outer graphics and the code rotates the inset `tom2` in the same way. The only difference is that `tom2` is projected orthographically instead of perspectively.
To do this, I used and adapted code from [Heike](https://mathematica.stackexchange.com/users/46)

Don't set `ViewPoint` to infinity!!! Just set it any number large enough, the effect will equivalent to setting to infinity.
Try for example the following
```
ListPointPlot3D[Tuples[Range[10], 3], BoxRatios -> Automatic,
ViewPoint -> {0, 0, 1000}]
```
for your example just change `ViewPoint -> {0, 0, ∞}` to `ViewPoint -> {0, 0, 1000}` or any number large than 1000 as you wish.
You'll be amazed at how simple it is to get rid of perspective. Rotate freely! : ) |

It seems to work fine. |
28,600 | I have plotted a figure of MoS2 crytal structure. But the actual output looks like the spheres are not in the correct position due to the perspective effect.
I obtained the correct position figure by setting the `ViewPoint` to `Infinity`. But when I rotate the figure, the infinity effect fails and the perspective effect takes place again.
I was wondering if there is a way to get rid of the perspective effect when you draw a graphic?
Thank you.

] | I think the only way to do this is by dynamically reseting the [`ViewMatrix`](http://reference.wolfram.com/mathematica/ref/ViewMatrix.html) to be an [orthographic projection](http://reference.wolfram.com/mathematica/ref/ViewMatrix.html#464375084). It was beyond my ability, patience, or inclination to figure how to decompose the `ViewMatrix` that is created when the graphic is moved into the components `ViewPoint`, `ViewVertical`, etc. It seemed to me that the front end usually make a discontinuous jump from the view point in the orthographic projection to the initial view point in rotated graphic. Discouraged by this apparent behavior, I opted for a hybrid solution.
I used an ordinary `Graphics3D` with `Dynamic` view properties and used `Inset` to insert the graphics `tom2` into it. The view properties of the outer `Graphics3D` are used to compute a corresponding orthographic projection `ViewMatrix` to be used to display the graphics `tom2`. So the mouse rotates the outer graphics and the code rotates the inset `tom2` in the same way. The only difference is that `tom2` is projected orthographically instead of perspectively.

Don't set `ViewPoint` to infinity!!! Just set it any number large enough, the effect will equivalent to setting to infinity.
Try for example the following

for your example just change `ViewPoint -> {0, 0, ∞}` to `ViewPoint -> {0, 0, 1000}` or any number large than 1000 as you wish.

For example, if you wanted to READ information - e.g. User 123, then you should send a GET request with the id as 123.
Where the ID of the user is located, within the URL, is immaterial. Generally most routes specify the ID at the end of the URL. But you can certainly specify it where ever you like. You don't even need the http protocol to make a restful interface. so long as you can identify the resource - whether at the start of the uri or at the end - it doesn't matter. |
349,678 | I've seen Facebook's APIs that will sometimes start with resource id. Also, if the URI is for a business process as opposed to a fine grained resource, would it be acceptable to start the endpoint with an ID, e.g.
```
/{fine-grained-id}/businessProcess
```
So the ID does not represent an item in a list of business processes, but is the key resource ID needed for the process. | 2017/05/26 | [

I'm not familiar with the Facebook API, but you should avoid putting actions or processes in your URLs if the intent is to call that action by making a request to that URL. For example this is wrong
`GET /infrastructure/database/reshard`
Instead, the client should put the abstract `database` resources into the `resharding` state and then tell the server that is the new state of the database.
```
PUT /infrastructure/database
{state: resharding}
```
The only actions you can perform on a resource are defined in the HTTP spec (GET, POST, PUT, DELETE etc). HTTP is about state transfer. The client doesn't ask the server to perform an action on a resource it has (client: *please reshard the database*).
Instead, it changes the state of a resource (which is an abstract concept remember) and then uses the simple HTTP actions to let the server know it has updated this resource and the server should get in sync (client: *I've put the database into this new state of resharding, update your representation of this resource*)
The physical database gets physically resharded as a side-effect of the server syncing up its state of the resource with the state of the client. |

7,495,922 | protecting a page for Read and/or Write access is possible as there are bits in the page table entry that can be turned on and off at kernel level. Is there a way in which certain region of memory be protected from write access, lets say in a C structure there are certain variable(s) which need to be write protected and any write access to them triggers a segfault and a core dump. Its something like the scaled down functionality of mprotect (), as that works at page level, is there a mechanism to similar kind of thing at byte level in user space.

] | No, there is no such facility. If you need per-data-object protections, you'll have to allocate at least a page per object (using `mmap`). If you also want to have some protection against access beyond the end of the object (for arrays) you might allocate at least one more page than what you need, align the object so it ends right at a page boundary, and use `mprotect` to protect the one or more additional pages you allocated.
Of course this kind of approach will result in programs that are very slow and waste lots of resources. It's probably not viable except as a debugging technique, and valgrind can meet that need much more effectively without having to modify your program... | One way, although terribly slow, is to protect the whole page in which the object lies. Whenever a write access to that page happens, your *custom handler for invalid page access* gets called and resolves the situation by quickly unprotecting the page, writing the data and then protecting the page again.
This works fine for single-threaded programs, I'm not sure what to do for multi-threaded programs.
This idea is probably not new, so you may be able to find some information or even a ready-made implementation of it. |

] | First of all it seems that you are creating lots of string objects in the inner loop. You could try to build list of prefixes first:
```
linker = 'CTGTAGGCACCATCAAT'
prefixes = []
for i in range(len(linker)):
prefixes.append(linker[:i])
```
Additionally you could use `string`'s method `endswith` instead of creating new object in the condition in the inner loop:
```
while True:
line=f.readilne()
if not line:
break
for prefix in prefixes:
if line_1.endswith(prefix):
new_line='>\n%s\n' % line_1[:-len(prefix)]
seq_1.append(new_line_1)
if seq_2.count(line)==0:
seq_2.append(line)
```
I am not sure about indexes there (like `len(prefix)`). Also don't know how much faster it could be. | **About twise faster** than all theese variants (at least at python 2.7.2)
```
seq_2 = set()
# Here I use generator. So I escape .append lookup and list resizing
def F(f):
# local memory
local_seq_2 = set()
# lookup escaping
local_seq_2_add = local_seq_2.add
# static variables
linker ='CTGTAGGCACCATCAAT'
linker_range = range(len(linker))
for line in f:
line_1=line[:-1]
for i in linker_range:
if line_1[-i:] == linker[:i]:
local_seq_2_add(line)
yield '>\n' + line_1[:-i] + '\n'
# push local memory to the global
global seq_2
seq_2 = local_seq_2
# here we consume all data
seq_1 = tuple(F(f))
```
Yes, it's ugly and non-pythonic, but it is the fastest way to do the job.
You can also upgrade this code with `with open('file.name') as f:` inside generator or add some other logic.
Note:
This place `'>\n' + line_1[:-i] + '\n'` - is doubtful. On some machines it is the fastest way to concat strings. On some machines the fastest way is `'>\n'%s'\n'%line_1[:-i]` or `''.join(('>\n',line_1[:-i],'\n'))` (in version without lookup, of course). I dont know what will be best for you.

] | Probably a large part of the problem is the `seq_2.count(line) == 0` test for whether `line` is in `seq_2`. This will walk over each element of `seq_2` and test whether it's equal to `line` -- which will take longer and longer as `seq_2` grows. You should use a set instead, which will give you constant-time tests for whether it's present through hashing. This will throw away the order of `seq_2` -- if you need to keep the order, you could use both a set and a list (test if it's in the set and if not, add to both).
This probably doesn't affect the speed, but it's much nicer to loop `for line in f` instead of your `while True` loop with `line = f.readline()` and the test for when to break. Also, the `else: pass` statements are completely unnecessary and could be removed.
The definition of `linker` should be moved outside the loop, since it doesn't get changed. @uhz's suggestion about pre-building prefixes and using `endswith` are also probably good. | **About twise faster** than all theese variants (at least at python 2.7.2)

1. Avoid unnecessary operations, conditions etc.
2. Move everything you can out of the loop.
3. Try to do as few levels of loop as possible.
4. Use common Python practices where possible (they are generally more efficient).
But most important: try to simplify and optimize the algorithm, not necessarily the code implementing it.

] | You're problem already begins with your intersect call! There you will lose your "real" array data, because you compare everything in lowercase and assign it also in lowercase.
So your array\_diff won't find anything, because it's case sensitive and if you make it case insensitive you still doesn't have the real data.
You already have to change your intersect. So your code should look something like this:
```
$intersect_sku_array_s = array_intersect($valid_sku_array, $qb_sku_array);
$intersect_sku_array_is = array_uintersect($valid_sku_array, $qb_sku_array, "strcasecmp");
//^^^^^^^^^^^^^^^^ See here I used 'array_uintersect' with 'strcasecmp', so that you don't lose your case
```
After this you can do your array\_diff normal like this:
```
$diff = array_diff($intersect_sku_array_is, $intersect_sku_array_s);
``` | I'm not familiar with `dd` as a PHP function.
Your question is not entirely clear, but if you are just trying to look at the contents of the array `$diff` there are many ways to do it...
