Settings in iPhone errors

So silly question here but if someone would humor me and lend any advice I would appreciate it SO much. I’ve had some issues since I’ve created my apple account, but one thing I keep noticing specifically that confuses me (my Apple ID once said it can not be changed, now it allows me the option to change my Apple ID and phone/email everything)
I wouldn’t be so concerned with this, but I’ve had reasons for safety/security concerns and then I noticed this. I see many “null” type messages in my data when I view it directly from my device as well. I’m not tech savvy at all so this is all beyond me. Forgive me please if I’m not posting this correctly. I receive error messages from apple when trying to download my data even. I’ve updated and reset my phone before but it doesn’t help. I want to just know this is user error on my end but I’m not finding information to confirm that anywhere I try to look. Thank you so much for anyone who might be able to point me in the right direction.

Twilio Dialogflow is too slow

I have integrated Dialogflow with Twilio Number using webhook. Issue that I am facing is the delay. Once the user is saying/asking something it is taking 8-9 sec to get the response back. Not sure if you have faced similar issues but is there any solution for the same. Delaying is causing a big issue and none of the client is up for this.
FYI I am using twilioClient and require('twilio').twiml.VoiceResponse for all the responses.
Not much to go on, but on the Twilio side which is acting as simple conduit, you can look at Request Inspector, to see how many milliseconds it is taking for the request to your application server to return a Twilio Markup Language (TwiML) response, which tells Twilio what to do.
I am not overly familiar with Dialogflow. Twilio offers a multi-channel Natural Language Understanding (NLU) solution, Autopilot, which can provide an AI bot experience. You could also investigate that solution.

App that will pull data from website flash game

Basically I need information on how to pull data from a flash game webbased client and put that data into an app. The game is evony.com its a webbased flash game. I can probably figure out the coding such as parse the login and password and display the information in the app. What Im have major problems is following,
How can I find out what data in what format is being transmitted from
webbased client to their server.
What software, preferably free, is out there that will do this for me?
Is there any tutorials, explanations, pointers anything describing this
on the inet because I have searched high and low without success.
I think the problem is because I am a beginner, I do not know the correct wording to serch for to find this information. It's a little like a needle in a haystack :) If you know what you want but dont know what it is called, get a new hobby :(
VERY much appreciated for any help, pointers, explanations, descriptions, tutorials or anything that can help me with this, very very much appreciated all.

The tool of choice to get started is WireShark. Its a software to monitor in- and outgoing datatransfer. It's very powerfull and a bit complex to get filtering right. Try something different to get started (e.g. do a ftp-login and try to "steal" your own password).
In Step two, you need to reverse engineer the communication between your client and the server. Thats the fun part. If it is encrypted, bad luck.
If you want to read the data, you can use libraries like LibCap to get the data in a language of choice. The flash player interacts with the game and you read the data transmitted.
If you are going for a stand alone program without the running flash client, you need to write your own client based on the protocol you got from step two. Be prepared to be kicked and banned permanently on the slightest error. I haven't checked on this one but every MMO I know and I can imagine do prohobit such tools.

How to implement an online whiteboard facility?

I am planning to implement an online whiteboard. But I have no idea where to start. I went through many creative applications online, most of them seemed to have been implemented using Adobe Flash. Can anyone provide ideas on how to start off with the application regarding both the front-end and back-end implementation.
As a web developer I would suggest you to look at HTML5 Canvas as it allows you to draw/scribble on it. You must consider using fabric js So you would need HTML5 and javascript.
To share your whiteboard scribbling or anything you ll have to push real time data to other clients/user(aka browser), you should consider websockets , socket.io
Here this question can you help you I think. That should get you started. Let us know if you face any specific problem.

Predictive Monitoring (Nagios?)

i am searching for a predictive monitoring solution which is actually free and able to discover trends. I've been reading about a lot of monitoring software like Zabbix, Zenoss, OpenNMS etc. but it doesnt seem that any of these are able to discover trends (e.g. the used memory of a webapplication increases from day to day)...
We are currently monitoring our systems with Nagios, but as everyone knows, Nagios is perfect to monitor stuff but not pretty good at analyzing/reporting...
Is there a way to implement predictive monitoring at the moment? Like the monitoring software is able to discover trends and throws an alert before something gets to a critical point?
Thanks in advance and sry for my poor english!
Greets,
Marley
Well, i have been waiting quiet a while now and it seems not even Stackoverflow is able to help.
I decided to gave up on this and hope for Zabbix to implement the feature within 2012.. They said it might be released with version 2.2
:(!
I don't know if you were able to solve this issue, but i have this small project that may help you out https://github.com/ricardomaraschini/nada
Take look at www.opservices.com.br. It's nagios based and have predictive baseline monitoring and alarming.
