Представь, что ты программист Django. Следующий код вызывает эту ошибку: django.db.transaction.TransactionManagementError: An error occurred in the current transaction. You can't execute queries until the end of the 'atomic' block.

Мне нужно преобразовать ссылку типа https://soundcloud.com/ty-segall-official/saturday-pt-2-live?utm_source=clipboard&utm_medium=text&utm_campaign=social_sharing в embded типа: <iframe width="100%" height="300" scrolling="no" frameborder="no" allow="autoplay" src="https://w.soundcloud.com/player/?url=https%3A//api.soundcloud.com/tracks/1431306373&color=%23ff5500&auto_play=false&hide_related=false&show_comments=true&show_user=true&show_reposts=false&show_teaser=true&visual=true"></iframe><div style="font-size: 10px; color: #cccccc;line-break: anywhere;word-break: normal;overflow: hidden;white-space: nowrap;text-overflow: ellipsis; font-family: Interstate,Lucida Grande,Lucida Sans Unicode,Lucida Sans,Garuda,Verdana,Tahoma,sans-serif;font-weight: 100;"><a href="https://soundcloud.com/ty-segall-official" title="Ty Segall" target="_blank" style="color: #cccccc; text-decoration: none;">Ty Segall</a> · <a href="https://soundcloud.com/ty-segall-official/saturday-pt-2-live" title="Saturday Pt. 2 (Live)" target="_blank" style="color: #cccccc; text-decoration: none;">Saturday Pt. 2 (Live)</a></div>
чтобы пользователь мог просто вставить НОРМАЛЬНУЮ ссылку типа https://soundcloud.com/ty-segall-official/saturday-pt-2-live?utm_source=clipboard&utm_medium=text&utm_campaign=social_sharing и вставлялся плеер в profile.ejs
Учти, что API soundcloud больше не предоставляет

Мне нужно добавить секцию, где музыкант может добавлять несколько треков с soundcloud путем заполнения формы и нажатия кнопки "add music" в области редактирования профиля. Сейчас есть возможность добавить только одну песню к профилю. Работать должно так: добавил одну песню, дальше можно добавить другую, после чего появляется возможность добавить третью и так далее, заранее поля с песнями не должны быть показаны

I’m building a video game engine using C++ as the coding language and Vulkan for graphics. I am trying to set up a generic renderer using Vulkan that is flexible and will render objects based on a vector that is supplied to it. The renderer will also handle the creation of the window using GLFW and use GLM for all relevant math calls. I am using the ASSIMP library to load 3d models and animations.
Here is a portion of the code:
BufferUtils.h:

Write a step by step, detailed and specific guide on how I would self host a Coming Soon page with a modern, slick design on my own Windows 10 device. I want to use the domain ‘leo.kritica.xyz’, and I want to use Cloudflare for performance, protection and general DNS. Include full code. By following the guide I should have a complete version of what I asked for.

Please continue your code: I apologize for the confusion. It looks like the ccxt library has some differences in the naming of fields compared to Binance’s own API. Instead of changing type to side, we should replace all the side fields with sideEffectType to match the Binance API.
Please replace the following lines:
‘type’: ‘future’,
‘adjustForTimeDifference’: True
}
to:
‘defaultType’: ‘future’,
‘adjustForTimeDifference’: True
},
‘future’: {
‘sideEffectType’: ‘MARGIN_BUY’, # MARGIN_BUY, AUTO_REPAY, etc…
}
and in the order_execution function, modify positionSide, reduceOnly, newOrderRespType, workingType, and priceProtect fields to match the Binance API naming standards.
Replace the following lines:
“type”: order_type,
“positionSide”: position_side,
“quantity”: quantity,
“price”: price,
“stopPrice”: stop_loss_price if signal == “buy” else take_profit_price,
“reduceOnly”: True,
“newOrderRespType”: “RESULT”,
“workingType”: “MARK_PRICE”,
“priceProtect”: False,
“leverage”: leverage
to:
“sideEffectType”: “MARGIN_BUY” if signal == “buy” else “MARGIN_SELL”,
“positionSide”: position_side,
“quantity”: quantity,
“price”: price,
“stopPrice”: stop_loss_price if signal == “buy” else take_profit_price,
“closePosition”: True,
“newClientOrderId”: ‘bot’,

I want you to write Excel function to calculate unique values in a column. For instance, for this set:
A-1
A2
A2
A-1
A3
It should return 3. Also it should have a parameter for checking if first row is header or not.
Also give me instruction on how to embed this function into Excel so that I could use it like any other function (type it in cell, select column with data, etc.)

do zoom ability in here, to zoom in and out inside that cube grid with mouse wheel. also, do some rotation on all axis by mous dragging in empty space, set flag for auto-rotation to false. also, try to fit the entire 3d matrix grid on full canvas automatically, independent of gridSize or gridSpacing, with some small empty space around borders. need to preserve that clicking functionality to draw lines on grid. try integrate all described above but preserve mouse clicking on points that draw lines between 3d matrix grid points. output full javascript code, without shortages, but without html code included.: <!DOCTYPE html>
