gps | Python script to interact w | Map library

I'm doing a project with a Ublox NEO 6m gps and a Raspberry Pi 4 model B and I'm stuck on the following error:

I am trying to get the keys of the properties and make them column names. How do I do this please? The list just goes on and on so I am thinking a loop to get the keys as column names and the items as rows. How do I do this please?

I don't know how to better describe it. I was working on react-native project, something happened and I can't run it anymore for some reason. I'm getting weird messages like some function could not be cloned.

Using bokeh example of displaying mercator map here, how do I center the map around a specific set of GPS coordinates?

In TTN they are no longer supporting large decoders.

I know what the decoder needs to be in TTN, it is in my DECODER function, but dont know how to execute it in the function node.

If you use inject Payload [1,2,3] RAW, it injects the raw payload that is msg.payload.payload.uplink_message.frm_payload into the decoder.

The DECODER needs to decode the raw payload and output it in msg.payload.uplink_message.decoded_payload

If you use inject Payload [1,2,3] Decoded in the flow you see how the end result needs to look like and the decoded msg.payload.uplink_message.decoded_payload

I am still learning JavaScript.

The code in the function node

I have the following problem:

I built an app that has 6 buttons and each of these buttons is assigned a CL region. I have a GPS track file that provides the app with locations and simulates a walk.

Now buttons should turn yellow when the region assigned to them is reached. It works so far, but the problem is that I don't know where to ask whether or not to reach the Region of Button. I tried .onAppear () {if ...}, but that is only triggered once and I need something that monitors the If statement all the time.

Is there anything?

Thanks in advance

here my code:

I'm not sure if the title makes sense, it was the best I could come up with, so here's my scenario.

I have an ASP.NET Core app that I'm using more as a shell and for DI configuration. In Startup it adds a bunch of IHostedServices as singletons, along with their dependencies, also as singletons, with minor exceptions for SqlConnection and DbContext which we'll get to later. The hosted services are groups of similar services that:

1. Listen for incoming reports from GPS devices and put into a listening buffer.
2. Parse items out of the listening buffer and put into a parsed buffer.

Eventually there's a single service that reads the parsed buffer and actually processes the parsed reports. It does this by passing the report it took out of the buffer to a handler and awaits for it to complete to move to the next. This has worked well for the past year, but it appears we're running into a scalability issue now because its processing one report at a time and the average time to process is 62ms on the server which includes the Dapper trip to the database to get the data needed and the EF Core trip to save changes.

If however the handler decides that a report's information requires triggering background jobs, then I suspect it takes 100ms or more to complete. Over time, the buffer fills up faster than the handler can process to the point of holding 10s if not 100s of thousands of reports until they can be processed. This is an issue because notifications are delayed and because it has the potential for data loss if the buffer is still full by the time the server restarts at midnight.

All that being said, I'm trying to figure out how to make the processing parallel. After lots of experimentation yesterday, I settled on using Parallel.ForEach over the buffer using GetConsumingEnumerable(). This works well, except for a weird behavior I don't know what to do about or even call. As the buffer is filled and the ForEach is iterating over it it will begin to "chunk" the processing into ever increasing multiples of two. The size of the chunking is affected by the MaxDegreeOfParallelism setting. For example (N# = Next # of reports in buffer):

• N3 = 1 at a time
• N6 = 2 at a time
• N12 = 4 at a time
• ...

• N6 = 1 at a time
• N12 = 2 at a time
• N24 = 4 at a time
• ...

• N12 = 1 at a time
• N24 = 2 at a time
• N48 = 4 at a time
• ...

• N24 = 1 at a time
• N48 = 2 at a time
• N96 = 4 at a time
• ...

This is arguably worse than the serial execution I have now because by the end of the day it will buffer and wait for, say, half a million reports before actually processing them.

Is there a way to fix this? I'm not very experienced with Parallel.ForEach so from my point of view this is strange behavior. Ultimately I'm looking for a way to parallel process the reports as soon as they are in the buffer, so if there's other ways to accomplish this I'm all ears. This is roughly what I have for the code. The handler that processes the reports does use IServiceProvider to create a scope and get an instance of SqlConnection and DbContext. Thanks in advance for any suggestions!

I download an image by cURL on KOBO Collect server. The download is fine, however it overwrites the exif data in the image. I use Code Igniter 4.

I would like to get the exif data contained in the image before or after the download, with PHP or javascript. This data must be stored in my database (gps etc) My code :

Basic version info first:
