Just bought a course on this platform. Although i paid attention not to buy a subscription for $80 a month, i fell for it. The course was about $30 itself.

The majority of the courses are very overpriced compared to what you find online (or in other learning platforms) and if you do not speak Russian, the voice over is just bad and makes it barely possible to follow the explanation.

The majority of the courses are in Russian btw.

Hope it can help someone!

Hi guys, I have just started to sing at the age of 32. I do not have background in music, nor do i want to make music my career/education.

I have found my singing teacher through word of mouth, yet i was wondering, is there any platform/website or whatsoever to find fellow singers or musicians in general?
Like if I wanted to sing in a band as a hobby at some point, where do I even go? Sure, there are music schools and announcements around but globally no internet solution at all?

I have already asked few friends and the music teacher himself, they all said that it goes 100% word of mouth to meet/find other people. So I hope they were wrong :)

I am thinking to buy a new laptop for myself. I work as a data scientist/ backend dev and 16 GB ram are more than enough for my work.

Reading many reviews and specs, it seems that the e15, although being newer and more expensive, has very little to offer performance wise? If I wanted i7 processors i still need to pay extra for that in the e15 and that seems the only big improvement.

Like having a fingerscan pad, 10% higher resolution or longer battery life are almost negligible improvements for me.

Did I oversee anything? Any experiences/tips about these laptops?

I like thinkpad and well if there are other models with similar specs, i would be open to take a look at them!

I am trying to connect many sensors (around 8) to esp32 outputting analog values. The ADC on the esp32 are very noisy so I cannot use them, otherwise they would just be fine for the job.

What are the alternatives to get something like this to work? All I want is to read those values. I thought an I2C driven board like this could help, any tips if I am on the right path or not?

I would like to take my gf out to some classy venue during the week, around 21 or so. We work, so having cocktails is not a must, it would be nice if they have some desserts or something more than just beer/wine like most bars do. I do not care if it is a restaurant/bar or whatever, i would like it to have something 'different' than the most standard cafes around town.

Thank you for any answer!

I am trying to connect 6 electromotic actuators to esp32 (by clicking here you can download the datasheet , I am using SSA161.05) which need 0 to 10 V input to be controlled.

What is the simplest and most robust way to do so?

I think that using the GPIO + a voltage amplifier (multipliying the GPIO x3.03 basically) for each actuator can be a simple option but I would like to hear a second opinion on this as I am a noob.

ESP32 has only 2 DAC's, which are (as far as I know) the only way to connect to certain devices like a relay.

If I wanted to direct 8 relays, how can I achieve this?

The only solution I could think of is to have several esp32 strung together, but it seems wasteful to just use esp32 purely for the DAC, while everything else (ADC, code..) can just run on 1 esp32. Any ideas or insights?

So the situation is as follows:

A data analyst is busy with an analysis using Excel. It turns out that they cannot validate intermediate results as that would require either advanced knowledge of Excel or basic python scripting knowledge. Both of those knowledge "upgrades" are apparently not viable/desirable options for the analyst.

To help this situation, the Data Science team created a few scripts and a streamlit app that the data analyst can run on their own. Also, the analyst got a clear explanation of which code lines to modify to in case he wants to change their model, as that it is like 10 lines of code in pandas itself. The data analyst has basic coding knowledge of Java and C++ an

Hello, I have used esp32 for some pet projects. I like it a lot but when it comes down to write more 'compute' intensive code, esp32 is just quite limited. I was looking into more expensive alternatives and found this revolutionPi.

If anybody has used both devices, besides the cost and the tech specs, can we just say that revolutionPi can do everything has esp32 does + a lot more compute?

I have been hanging around this sub for a while and i see some questions on how to become a ML engineer as a data scientist almost daily. Is there anything like this already? I am curious!

I did the switch myself almost 3 years ago and back then there was nothing. All my learnings were put together the hard way and I feel like I spent a lot of time looking for information, not the best way to spend time imo!

Hello,

I hope this is not off topic. I work as a contractor and whenever I need to send some documents to my accountant, I will mail him or send a message to whatsapp with the document.

He told me that this process is very chaotic for him and more 'document-intensive' clients where he receives hundred of documents each quarter. So what do you use to receive documents? Is there any cheap software that makes this process a bit more organized?

He told me that classic document-sharing software like dropbox, google drive etc would be way too expensive for him.

I am a data scientist and I did a project for maintenance of PV systems. It strucked me that there is basically nothing monitoring their performance at scale. I analyzed several mid size PV installations (100 square meters or more) and they had really zero monitoring. Speaking to few people, heard the same about smaller size and private installations.

A guy in the industry told me that sending data to the cloud (IoT system) is often too expensive or unreliable (due to the data connection).

I am based in north europe, so I wonder if abroad things are more advanced or if PV systems are just never monitored by default.

What is your experience? Is it really like this?

Mi chiedevo se fosse legale recensire i professori universitari. In caso non fosse legale, chi avrebbe la colpa? Il sito web o l'utente che ha fatto la recensione?
