QUESTION
Hello IM trying to parse this type of json :
...ANSWER
Answered 2020-May-25 at 17:04There should be more on the server-side or request causing the 422 error. You might want to check them.
To answer your question, since the data is a list of Record
, the _getRecords
function should be more like this.
QUESTION
The intention is to display an item from a list of objects but on every page refresh, the item should be randomly chosen from the list. Here, Testimonials
is the list and I want to display any random item from this list. If I use a constant, it works fine. When I use, the random function, it does not display proper image with its associated item message.
I use React 16, Next.js, styled components as the tech.
The problem is in rendering of Employees section. The console displays a warning as

I'm following Twillio's guide on responding to incoming SMS.
Everything works as expected. I'm getting the webhook and the reply is sent to a verified number (I'm using a trial account).
The problem I'm having is getting the contents of the incoming message. I tried to get the contents through $_POST
and php://input
but both are empty. I want to get the contents in order to send to our info mailbox.
This is my replyToSMS.php:

Answered 2020-Jan-17 at 23:12Many thanks to @ceejayoz who pointed out the answer. The docs mention that$_REQUEST['Body']
contains the contents of the incoming message.
So it's not neither in $_POST
nor in php://input
. It's in $_REQUEST
which is the object that contains all the data that is sent by Twillio webhook as it sends the API request to your server endpoint.
These are fields that the Request object contains:
QUESTION
I'm attempting to lay the foundation for a relatively simple messaging system using Twilio API and its Python wrapper. Users should be able to text a keyword and receive back a string of responses.
The problem is, using the suggested HttpResponse() package from Twilio's documentation, when I loop through the messages to add them to a response chain, they hit Twilio in a block, and sends the service sends them in a seemingly random order, which really compromises the readability of the block.
Here's a simplified version of the loop I'm running in Django to create the response:
...ANSWER
Answered 2019-Nov-15 at 18:34According to Twilio, this cannot be done. as they simply do not have control over the delivery process.
Twilio cannot guarantee that SMS messages sent from your Twilio phone number will arrive in order. While we will send the SMS messages you pass to us in the order that you’ve queued them, the SMS messages are delivered individually with no association to each other. The order of delivery depends on the carrier.
To help your users understand the order of your messages, we recommend that you append a page reference following each message, for example 1/3, 2/3, 3/3.
In SMS, the shortest message is typically sent the fastest. You could potentially design your messages to be ordered by size. That might reduce the frequency of error.
Another option might be to bundle them all into one large 1600 character message and having the carrier deal with breaking it apart. It would depend on whether concatenated SMS is reliably supported by carriers in your client base. That might deal with the order issue.
QUESTION
I live in a very safety/critical Ada-ic environment, and have taken the habit of having well defined and bounded type definition. I am also confronted to lots ASN1 usage/evangelists.
One of the key features that some people around me define as superior in ASN1 over protocol buffers is the ability to define, and therefore check, data range.
So,
- Is it true that protocol buffers do not have any range definition system ?
- Are there any means on top of protocol buffer that could provide such a feature ?
Usual numerical types definition such as int32, int64 is out of scope here.
I read this Google overview and found no reference to any data range definition. Except for features concerning the enum management/representation, and some ordering features.
To give some other references, I heard of/read the links below and became aware of an Ada implementation project.
Does anyone know of an Ada plugin for protocol buffers?
which led to

Yes

You write code that checks the values are in the expected range.
QUESTION
I could use some insight from a Twilio Evangelist. My company is using Twilio to call patients registered to our platform. The Twilio device is setup upon the user logging into the system and then they can either call a patient from their Patient Profile page or enter a manual number from their clinic's to call a prospective patient. I'm encountering an interesting error however as depending on the location the call is initiated from we want a different handler function to fire when the call is Disconnected. As it stands right now, when you first initiate a call from a Patient Profile page and pass a patientCalled object to the callPatient function the system works fine. However if you then move over to your Clinic page and initiate a call in which case patientCalled is "none, the event handler from the call initiated on the Patient Page still fires.
Can you only register an event handler to a twilio Device connection state once? Here's my code, we're running react-redux.
...ANSWER
Answered 2019-Sep-30 at 05:57Twilio developer evangelist here.
When you setup the Device
here, you are using it in singleton mode as a long lived object. Every time you make a call with the device you are then trying to add to the event listeners by calling to device.on
. It's not that you can only attach one listener, more that you keep attaching more listeners.
There's a couple of things you can do here.
Either, you can embrace the singleton device and set up all your event listeners when you call Device.setup
. You'll need to handle connecting and disconnecting to calls regardless of which page you are looking at.
Alternatively, you can create a new device object per page, by using the device constructor available in version 1.5.0 and up. You can listen and react differently to different events on each device.
Let me know if that helps at all.
QUESTION
I'm trying to have the ability to update a call to dial it into a conference, and then I want to keep track of which phone numbers are in the conference. I'll already have the phone number before updating the call, so my plan was to add it as parameter to the statusCallback, then when someone joins, I'll know which phone number has joined (or left). Here is the Twiml I'm using to update the call into the conference.
...ANSWER
Answered 2019-Jul-24 at 10:12Heyooo Developer Evangelist here.
There are two ways to approach this.
1. Persist the call information viaCallSid
yourself
When you receive the initial phone call and you put people into the conference, what you could do it to persist the call information (including the phone number) on your end and use the CallSid
later to reference it when you receive the statusCallback
hook. This way you would have all the information at hand using the available CallSid
when the statusCallback
hook comes in.
statusCallback
While the statusCallback
hook doesn't include the call details what you can always do is to fetch the call information again by using the CallSid
. This way you can take the information from StatusCallbackEvent
and merge it with additional information after you received the call details.
Both approaches have pros and cons but are similar in the way that you have to get the call information from "somewhere".
The first approach needs you to find a way to persist call information. This brings additional overhead in your application.
The second approach saves you the need to persist call details but introduces an additional API request.
As always – it depends on your case. I hope that helps. :)
QUESTION
I'm using kubectl to control a local microk8s installation. I configured a local Google cloud shell connection in order to avoid the ridiculous provisioning of the machine available through the GKE dashboard.
Now, kubectl
commands seem to be randomly executed on microk8s and GKE. I want not only to fix this, but prohibit this scenario for the future.
The possibility that kubectl
can refer to different environment is a horrible idea apparently founded in concept of the kubectl
CLI which provides no way to specify a remote cluster. It can lead to accidental changes on production systems. Even a hardcore 12-factor evangelist will have a local cluster installed for development.
ANSWER
Answered 2019-Jun-12 at 19:49kubectl config use-context
command can be used to modify, whom kubectl talks to.
configure access to multiple clusters by using configuration files. After your clusters, users, and contexts are defined in one or more configuration files, you can quickly switch between clusters by using the. configure-access-multiple-clusters/
QUESTION
Not looking for opinions. I'm searching for data.
As it is now, I want to become a webM evangelist. However, I assume there are some actual technical reasons why mp4 is preferred over webm in the bigger picture. I want to know them so I can be accurate in my assessments.
I'm working on developing a broadcast video messaging graphics engine (think chyron) and using the Chromium engine like OBS does for messaging. So far the results have been excellent.
One of the best features I've found is using webm for video. I should note I am using small (640x480 max) videos as graphics that are on top off a larger full HD video.
Not only does it seem to have a better compression:quality ratio than mp4 for my use case, the most important thing is that it has full alpha support, which allows for excellent layering of video objects on top of each other in the HTML DOM, in real time, with no noticable performance hits.
Aside from it's predecessor, FLV, I can't think of another high quality, high compression codec that also supports alpha. I feel like you are stuck using pro-res 4444 or the ancient animation codec to reliable distribute video with an alpha.
So, that said, are there technical reasons why webM isn't more adopted than mp4?
I already know the obvious, that there is dedicated hardware to decode mp4. But, is there any technicality that would prevent a hardware webM decoder? I really want to understand more what the benefits of mp4 are over webM, which i assume is why it is more widely used than webM.
Thanks!
...ANSWER
Answered 2019-Jun-01 at 00:10You are confused. mp4 and webm (and flv) are containers, but you are comparing the attributes of the codecs they contain. For the most part, mp4 can contain every codec webm can, and dozens more. It’s also decades older, making it more accessible and more supported.
If you are trying to compare avc to vp9, the different is availability of h264 decoders in devices is much greater. Vp9 is also often decoded in software, reducing battery life. And for encoding, avc is much (much much) faster, hence much cheaper. So the only justification is if you can encode vp9 once, and send the same copy to thousands of viewers to make up the cost in reduced bandwidth. If only a couple hundred people download the video, vp9 cost more than it saved.
Finally, change is expensive and time consuming. There must be clear and justifiable reasons to do so.
