QUESTION
I have below Date column in character (from ENTSO-E platform). I want to convert into Date and extract the end part of this Interval ([1] "01.01.2021 00:00 - 01.01.2021 01:00"). I am receiving error "character string in unambiguous format". Any suggestions how can I extract the second part of the interval that is in character format to a Date variable in R?

QUESTION
I have a large dataframe made up of 8 different datasets, sample of three with different time zones below. I import the data and then rbind the 8 dataframes into one df. I want to be able to run analysis and ggplot the whole dataset or sections of it keeping the Date_time timezone correct to each area.
I recently found that dataframes in R apparently don't support multiple timezones in one column, so all following df added using rbind take on the timezone of the first data (df$Date_time changes from imported value), I've tried different ways to overcome this issue:
Saving the dataframes as a list, and creating a list of the 8 lists keeps the local time zone correct in listx$Date_time but ggplot doesn't allow plotting from a list, and when i convert back to dataframe the timezones are all changed again.
I created df$tz column to have each time zone in the file and I tried this: solution to create a fixed UTC time but this is a character string df$UTC and I'm not sure how to make R and ggplot plot the data with the correct timezone information.
df$Date remains true to the different timezones because time is stripped, and df$time_ser remains correct as the date is stripped.
Do I need to include a function to calculate the actual local time in every analysis I do as it runs - very time consuming, or is there some other way to do this.

Answered 2022-Mar-25 at 11:25I want to be able to run analysis and ggplot the whole dataset or sections of it keeping the Date_time timezone correct to each area.
I'm interpreting this as saying "I want to plot all data in local time", i.e. I want 11am in Auckland to be equivalent to 11am in Lima/Tokyo.
One way to achieve this is to use the lubridate::force_tz
function, which changes the time zone of a POSIXct object without adjusting the "time" component.
QUESTION
I've recently begun trying to Dockerize my services and I'm to the point of Dockerizing everything that already has an image built. Now I'm trying to build an image for facileManager (FM) which doesn't yet have one. I've got it mostly working but I'm having an issue when running it behind Nginx. FM is normally an apache-php app and doesn't include install instructions for Nginx. What I've noticed with my container/image is that it works ok when I connect directly to it through a published port but if I try to connect to it through Nginx it errors out complaining about the .htaccess file not working. I'm not an expert in either Apache or Nginx so I did my Googleing but didn't come up with much beyond Wordpress having a similar issue with it's "pretty urls" so I'm hoping someone here can give a hand.
First here is the Github repo for the app: https://github.com/WillyXJ/facileManager/tree/ea159f5f6112727de8422c552aa05b6682aa4d79/server
The .htaccess file specifically is:

- include $request_uri in your proxy pass
- provide a resolver in your proxy location block
- declare an entry for your container in Docker's network stack
- use all lower case in your service name
Below is the configuration file I use to reverse proxy through to a Ubiquiti Unifi container. All my certbot is handled off site so I need not consider that here. If you compare our location blocks, the issue will likely become immediately apparent, but I'll explain for clarity's sake.
What you need to look at is your Proxy Pass directive. This is of course where the magic proxying happens. I notice that you have not been including the $request_uri, so any request nginx receives for bound.example.com/testpage1
, it will send a request to the upstream apache server for bound.example.com
. Of course if you need to include a port, as I have done here 8443
, this is the place to do it also.
If you include this variable, it should resolve your problem.
The following does not answer your question, but I thought I would include it also just as some helpful information.
Also, I just want to note that I have included a resolver. The IP address 127.0.0.11 points to Docker's internal DNS resolver. Chances are you won't need to include this, however I did so myself to ensure I didn't get odd problems. Lastly, I'd just like to recommend that you look into upgrading your SSL settings, to ensure that you are safe from attacks from weaker SSL / TLS versions.
I expect that adding the variable $request_uri to your proxy pass directive is all that is required to get your site working.

I've been successfully mounting volumes on Windows 10 in various projects recently using the example docker-compose.yml file below. For a new project today I needed to mount a folder from the Z:/ drive (a network mounted drive which appears as \\IP.IP.IP.IP\public\data (Z:)
when I navigate to that area in Windows File Explorer.
When I edit the volumes to point to locations on Z: (e.g. in the second docker-compose.yml below), the volumes are not mounted properly and are empty folders when I connect to the container via the CLI.
Any advice on getting the Z: drive folders to mount properly would be great, thanks.

I am attempting to get IronPDF working on my deployment of an ASP.NET Core 3.1 App Service. I am not using Azure Functions for any of this, just a regular endpoints on an Azure App Service -which, when a user calls it, the service generates and returns a generated PDF document.
When running the endpoint on localhost, it works perfectly- generating the report from the HTML passed into the method. However, once I deploy it to my Azure Web App Service, I am getting a 502 - Bad Gateway error, as attached (displayed in Swagger for neatness sake).

...ANSWER
Answered 2021-Dec-14 at 02:19App Service runs your apps in a sandbox and most PDF libraries will fail. Looking at the IronPDF documentation, they say that you can run it in a VM or a container. Since you already are using App Service, simply package your app in a container, publish it to a container registry and configure App Service to run it.

I have been learning buffer overflows and i am trying to execute the following command through shellcode /bin/nc -e /bin/sh -nvlp 4455
. Here is my assembly code:
ANSWER
Answered 2021-Dec-29 at 14:12As you can see in strace
, the execve command executes as:
execve("/bin//nc", ["/bin//nc", "/bin//nc-e //bin/bash -nvlp 4455"], NULL) = 0
It seems to be taking the whole /bin//nc-e //bin/bash -nvlp 4455
as a single argument and thus thinks it's a hostname. In order to get around that, the three argv[]
needed for execve()
is pushed seperately.
argv[]=["/bin/nc", "-e/bin/bash", "-nvlp4455"]
These arguments are each pushed into edx, ecx, and ebx. since ebx needs to be /bin/nc, which was already done in the original code. we just needed to push 2nd and 3rd argv[] into ecx and edx and push it into stack. After that we just copy the whole stack into ecx, and then xor edx,edx
to set edx as NULL.
Here is the correct solution:

The new image derives from php:8.1.1-fpm-alpine3.15

ANSWER
Answered 2021-Dec-23 at 11:20Huh. This surprised me a bit.
composer is correctly reporting the PHP version it's using. The problem is that it's not using the "correct" PHP interpreter.
The issue arises because of how you are installing composer.
Apparently by doing apk add composer
another version of PHP gets installed (you can find it on /usr/bin/php8
, this is the one on version 8.0.14).
Instead of letting apk
install composer for you, you can do it manually. There is nothing much to install it in any case, no need to go through the package manager. Particularly since PHP has not been installed via the package manager on your base image.
I've just removed the line containing composer
from the apk add --update
command, and added this somewhere below:

QUESTION
I have a dataframe that has a timezone-aware index, and when I try to insert a new row into this dataframe, it doesn't work, instead changing the type of the index to 'object'
(ie, it can't add in the row into the current type).
MRE below:
...ANSWER
Answered 2021-Nov-26 at 14:50Timestamp
objects are certainly of type 'object'
, and it is possible you cannot escape the index to take this type if you use Timestamp
s as index.
By "timestamp configuration" I understand "timezone", and that you want to insert new times in the same timezone.
Either you know the timezone from the start and data of all rows come from a source known to be from the same timezone. In that case you can specify the same timezone when you instantiate the
Timestamp
s.Or you do not know the timezone of the data in the first place, and you have new data coming from another source, so potentially from a different timezone, that you certainly know about. Mixing timestamps from different timezones is not a problem, since timezones should be taken into account when you compare them with one another. You can still localize them all later to a timezone you prefer.
