I am using the following code to retrieve the html code from a url. It is working fine for a url as:

• https://trends.google.com/trends/?geo=US However, not working for the following one, returning an error as

"The remote server returned an error: (429) unknown.'"

What could be the error or how to get more info about the error?

So I compiled and ran the following C program:

Whenever I tried to run my application it will not execute and show this error.

Error:

I have tried to search it but I did not get any useful information about it and most of all I did make changes to Web.config but still cannot find the web.config in my application. Any help which could solve this problem will be appreciated.

I have a pair of iterator, and I would like to use ranges::views::filter(some_predicate) on it (with the pipe operator). AFAIU I should first convert my pair of iterator into a view. I tried to use ranges::subrange(first, last) to do so, but I’m getting horrible error messages.

Note1: I’m using C++14 and range-v3 version 0.9.1 (the last version compatible with gcc-5.5). If the solution differs when using C++17/20 and/or when using C++20 std::ranges, I’m also interested to know what changed.

Note2: I find the documentation of range-v3 severely lacking, so I’m using cppreference.com. If you know a better documentation, I’m very interested.

EDIT:

In my real code, I’m wrapping a java-style legacy iterator (that has a next() method instead of operator++/operator*. I’m wrapping them in a C++-compatible wrapper. Then I tried to convert that wrapper into a view, and finally filter it. I reproduce a minimal example on godbolt. This use iterator_range as suggested, but it still doesn’t compile (see the second edit below).

I am trying to ingest JSON array data into Azure data explorer, as per this Microsoft article. (Only the JSON Array section) https://docs.microsoft.com/en-us/azure/data-explorer/ingest-json-formats?tabs=kusto-query-language

I have one table with two columns(messageId,Message) message contain json data and i want to extract this data into different columns. all of the fields from the array are just blank.

enter code here { 'data': { 'type': 'ABC', 'id': '1234567890', 'attributes': { 'event': 'update', 'logged_at': '2021-06-03T15:41:22.000Z', 'heartbeat_id': '12345678', 'gps_valid': True, 'gps': { 'distance_diff': 0.22, 'total_distance': 127.79 }, 'hdop': 12, 'fuel_level': 180.4, 'relative_position': { 'distance': '3', 'country_code': 'Uk' } },`

CODE: AMO | mv-expand data = message.data | extend type = data.type, id = data.id` }

We are using stream ingestion from Event Hubs to Azure Data Explorer. The Documentation states the following:

The streaming ingestion operation completes in under 10 seconds, and your data is immediately available for query after completion.

I am also aware of the limitations such as

Streaming ingestion performance and capacity scales with increased VM and cluster sizes. The number of concurrent ingestion requests is limited to six per core. For example, for 16 core SKUs, such as D14 and L16, the maximal supported load is 96 concurrent ingestion requests. For two core SKUs, such as D11, the maximal supported load is 12 concurrent ingestion requests.

But we are currently experiencing ingestion latency of 5 minutes (as shown on the Azure Metrics) and see that data is actually available for quering 10 minutes after ingestion.

Our Dev Environment is the cheapest SKU Dev(No SLA)_Standard_D11_v2 but given that we only ingest ~5000 Events per day (per metric "Events Received") in this environment this latency is very high and not usable in the streaming scenario where we need to have the data available < 1 minute for queries.

Is this the latency we have to expect from the Dev Environment or are the any tweaks we can apply in order to achieve lower latency also in those environments? How will latency behave with a production environment loke Standard_D12_v2? Do we have to expect those high numbers there as well or is there a fundamental difference in behavior between Dev/test and Production Environments in this concern?

I am trying to follow this tutorial here - https://juliasilge.com/blog/xgboost-tune-volleyball/

I am using it on the most recent Tidy Tuesday dataset about great lakes fishing - trying to predict agency based on many other values.

ALL of the code below works except the final row where I get the following error:

I am having issues with my eBAY Scraper and can not work out why. Although it is pulling the data off fine, it misses SOME of the data OFF for the first row and then for each first row of every Loop and therefore the data is not in the correct row.

Q) Why is it missing the data at the start and then for each loop?

I think It may have something to do with the title extracting slower that the rest of the items, however I can not work it out as I am very limited with vba. I have attached a demo, for your viewing.

I am not looking for a full rewite of the code, just pointing in the right direction or a SLIGHT change to MY code. As I stated I and very limited in vba, I can understand my code, anything more advanced will be out of my depth.

I have colour coded it so you can see better

This is what it is doing

When It Should be This

For some reason it misses out Price, Condition, Former Price & Discount for the first item on start and EVERY Loop. For every loop that it misses the items out the Price, Condition, Former Price & Discount become MORE out of line

1st Loop - Items are NOW 2 rows out of line

2nd Loop - Items are NOW 3 rows out of line

As I searched 3 pages (2 pages + 1 extra) and it looped 3 time it has missed the first row on each loop. I am 3 rows out. I think this may have too do with the Title of the item as it extracts a bit slower then the rest of the items

This is my code

I have an app that communicates with a bluetooth device, and I'm trying to replace that app with some code.

I tried using C# InTheHand nuget, Microsoft's Bluetooth LE Explorer, python's sockets and others to send data and see what happens.

But there's something I still don't understand - in each way using different libraries I saw in wireshark a different protocol: ATT, RFCOMM, L2CAP...

When I sniffed my bluetooth traffic from my phone using the app mentioned before, I saw mostly HCI_CMD protocol traffic.

How can I choose the protocol I want to send? Is there a simple package for that? something to read?

Do I need to build the packet myself? including headers and such?

Thank you!

Update: Using Microsoft's Bluetooth LE Explorer I was able to send a packet that lit up my lamp, starting with 02010e10000c00040012(data)
Using bleak I was able to send a packet starting with 02010e10000c00040052(data)
the difference makes the lamp not ligh up and I'm not sure if I can change it via bleak as it's not part of the data I send
