QUESTION
This is my first post here and I am not that experienced, so please excuse my ignorance.
I am building a Monte Carlo simulation in C++ for my PhD and I need help in optimizing its computational time and performance. I have a 3d cube repeated in each coordinate as a simulation volume and inside every cube magnetic particles are generated in clusters. Then, in the central cube a loop of protons are created and move and at each step calculate the total magnetic field from all the particles (among other things) that they feel.
At this moment I define everything inside the main function and because I need the position of the particles for my calculations (I calculate the distance between the particles during their placement and also during the proton movement), I store them in dynamic arrays. I haven't used any class or function,yet. This makes my simulations really slow because I have to use eventually millions of particles and thousands of protons. Even with hundreds it needs days. Also I use a lot of for and while loops and reading/writing to .dat files.
I really need your help. I have spent weeks trying to optimize my code and my project is behind schedule. Do you have any suggestion? I need the arrays to store the position of the particles .Do you think classes or functions would be more efficient? Any advice in general is helpful. Sorry if that was too long but I am desperate...
Ok, I edited my original post and I share my full script. I hope this will give you some insight regarding my simulation. Thank you.
Additionally I add the two input files

I want to explode my table based on their 'KEY's and assort their names and emails separately into individual cols.
In Python such scenarios are dealt easily(like we use explode in pandas). since I've just started with SQL I'm finding it difficult to get my feet wet. My googling didn't help me even next to were i want, hence reaching out to the community as a my last resort for some guidance. In essence i'm trying to expand my table with my KEY as the index and the names and emails exploded across multiple cols.
my table:
KEY FIRST MIDDLE LAST EMAIL FLAG_GENDER FLAG_DESCENT 1 ROBIN A SIMPSON ROBIN@PROTON.COM M - 1 NICOLE P SIMPOSON NIC@YAHOO.COM F NA 1 SANDY LAYNE F NA 1 BRUCE NILLS BRUCENILLS@ M NA 1 ERIC WOOTEN ERICW@YAHOO.COM M NA 5 JUDY THAMES JUDYTHAMES@YAHOO.COM F NA 5 JUDY THAMES JUDY@GMAIL.COM F NA A290 RENN J JOHNSON RENNY@COMCAST.COM M C K890 JAMES RODRIGUES NA M L 189 BECKIE KATE MOORS BECKIE@GMAIL.COM F - 189 BECKIE MOORSB@YAHOO.COM F - 189 MOORS BMOORS@GMAIL.COM F - 189 BECKIE KATE MOORS BECKIE@GMAIL.COM F -output table:

QUESTION
I know this question has been asked before, and I've seen several of the SO responses and read the AWS docs on the subject... I have a terraform module that, in part, builds out an ECS service, cluster, task, and Fargate container:
...ANSWER
Answered 2021-May-14 at 13:54The whole problem had nothing to do with AWS, but the server I am running (weblogic) failed to start because I was trying to mount EFS in /, which cannot be done as it would overlay many critical startup and credential files. If I had the whole filesystem already on EFS (which I did not, I used a blank filesystem), then this likely would have been fine. I mounted it successfully to a lower subdirectory and the container spun up and is running.

How can I display a decimal number so that the integer part appears larger text size and the decimal part smaller
I am working with smarty templates (php), I get a variable that already has the total price included, example "75.45 €" and I would like to highlight the integer part of a decimal number so that it appears larger and the decimal part smaller, to turn also has the euro symbol included in the string.
I put an example:
EDIT
Thanks to ProtoN is solved:

Answered 2021-May-07 at 11:09You need to explode the variable and just use basic HTML/CSS to style the different span's..
something like that
QUESTION
I made a contact form on my website and need to submit it to my proton mail using Node.JS and express.
Do I need an SMTP server? Can I do it without SMTP or not? Because it'll be very focused and not that big. It'll only send forms to my email.
...ANSWER
Answered 2021-May-03 at 16:11The Simple Mail Transfer Protocol (SMTP) is an internet standard communication protocol for electronic mail transmission. Mail servers and other message transfer agents use SMTP to send and receive mail messages.
SMTP is a mail transport system and yes, is required to send email.
You can either set up a send-only mail server (e.g Postfix Mailserver), or use the general purpose sendmail if you are just sending email to yourself.
You can also use your own email/password with nodejs, if you use gmail/yahoo etc, as long as you get your settings right.
QUESTION
I want to send a scheduled message to the Azure Service Bus with JMS.
My code is based on org.apache.qpid.jms.message.JmsMessage. I've found one solution for the given problem, but it uses org.apache.qpid.proton.message.Message which has .getMessageAnnotations(), which allows to edit message annotations and add some properties that are correctly recognized and processed by Azure Service Bus. My message impl is missing that method.
What I've found in offical docs and implementations in node.js, to schedule a message with Azure Service Bus, you need to send header BrokerProperties/brokerProperties which has valid json.
Other headers/properties will be marked as Customer properties and ignored by Azure Service Bus.
official azure docs about JMS says that setting ScheduledEnqueueTimeUtc is not officialy supported by JMS API. But it can be achieved manually by setting property.
So when I send message to the queue, then I can post process it in lambda and set some properties:
...ANSWER
Answered 2021-Apr-07 at 08:26My team is currently facing the same issue.
We found that the ScheduledEnqueueTimeUtc property is set in the MessageAnnotationsMap. Unfortunately, the org.apache.qpid.jms.provider.amqp.message.AmqpJmsMessageFacade, which is used by JMS, has set the getter and setter to package private. But we found out that you can use the setTracingAnnotation(String key, Object value) Method.

QUESTION
I want to use Qpid Proton on the raspberry pi 4 but I have trouble installing it. Well, it seems I could install it and I can use the examples from the Apache website.
https://qpid.apache.org/releases/qpid-proton-0.33.0/proton/python/docs/tutorial.html
However, the container's on_sendable callback does not seem to be executed. After doing some research, it seems I need to add a topic exchange with the qpid-config, which is part of qpid-tools.
However, those are not available to install, both with pip or apt ...
Do you know how I can install Qpid-Tools on the raspberry pi? Do I need to add a repository? And if so, where do I find it?
...ANSWER
Answered 2021-Mar-02 at 20:26It's doubtful that there exists a build of qpid-tools fir the ARM based distributions so the short answer is probably that you can't get those tools there. The longer answer would be that you would need to likely build the qpid C++ binaries yourself on your Raspberry Pi using the included INSTALL instructions to try and reverse engineer the needed requirements and platform configuration that would allow it to build on ARM.
If you figure out the requirements you could feed that back to the Qpid community although I don't think there is much ongoing momentum for the Qpid C++ broker.
You can download the source bundle from the Qpid project site here.
