kandi X-RAY | LSC Summary

LSC is a C++ library typically used in Internet of Things (IoT) applications. LSC has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

Copyright 2019-2021 SuperHouse Automation Pty Ltd www.superhouse.tv. A modular Light Switch Controller for DIY home automation projects. This system uses UTP cable (typically Cat-5e because it’s cheap) to connect light switches to a central controller. The light switches can be either very simple buttons or switches mounted in wall plates, or smart switches with a microcontroller embedded. ![Light Switch Controller prototype] Images/LSC-prototype.jpg). The LSC provides 12V power down the line to each wall plate, which can be used for LED illumination or to power more advanced light switches. Light switches pull one of 4 signal wires in the cable to 0V to indicate that they have been activated. The LSC pulls the signal wires high internally and detects when they are pulled low. RJ45 sockets on the LSC are connected to I/O channels via I2C addressable I/O buffers. Each RJ45 socket provides connections for GND, 12V, and 4 signal lines. An LSC can be built with different numbers of ports and interface options.

            What improvements can I do to my .vimrc to improve my experience in NeoVim?
            Asked 2021-Apr-26 at 09:44

            Welcome to Vim!

            I think most new vim users have been there. I certainly have! I wanted a 'vim as python IDE' and copied a whole bunch of stuff from every blog under the sun into my vimrc almost immediately after installing vim.

            After some time spent fighting with all the settings, plugins and remaps I didn't understand, I decided to go through my vimrc, line by line and comment out anything I didn't understand (nearly all of it).

            Then I used this more minimal vim for a while and whenever I decided I had a need for a certain feature, I checked the largely commented vimrc for anything that looked related, and/or googled for that particular feature only. Often you find that there is a built in method to do it with the core vim commands, and if not, then there are a lot of solutions for the problem (and often, you find that there is an even more powerful way that didn't occur to you - these are good days).

            But the key is to not try and coerce vim into a huge IDE overnight! Let it happen gradually and things will make more sense, and you'll end up with a vimrc that you understand and therefore be in a position to add to it and tweak it.

            The last thing I'll say is to recommend the following books:
            'Learn VimScript the Hard Way' by Steve Losh
            'Practical Vim' by Drew Neil, and his accompanying screencast series.
            (Also there is The Primagean who does high quality youtube tutorials)

            Having said all that, and acknowledging that an objective answer can't be given for your question, here is a minimal vimrc which has a few plugins and settings that do simple but very useful things (but do read up on them to understand how they work!):

            Altair '4.1.0' returning an empty chart
            Asked 2021-Apr-18 at 03:08

            I'm trying to add a symbol in my Altair chart so the user could know by color what each line represents in the chart, but when I plot it I receive an empty chart without the data I'm passing.

            Meanwhile I was debugging the code and I suppose the problem is located on the line color = alt.Color...

            ANSWER

            Answered 2021-Apr-18 at 03:08

            You cannot use "Symbol" as the chart color because it is not a column in your dataframe. You would need to reshape/melt the df first to create this column, e.g. with new_df.melt(id_vars=['amostra', 'media'], var_name='Symbol'] as per the pandas docs on reshaping.

            After quite a bit of extensive research, it finally works on my computer: the latest versions of the components (i.e. CUDA 11.2, cuDNN 8.1.0) are not tested and not ensure a working result in TF 2.4.1. Therefore, this is my final configuration:

            1. nvidia-drivers-460.39 have CUDA 11.2 drivers. However, you can still install CUDA 11.0 runtime and get it from the official NVIDIA archive for CUDA. Following the installing instructions is still mandatory (i.e. adding the path variables and so on).
            2. cuDNN library needs to be on the version 8.0.4. You can get it also from the official NVIDIA archive for cuDNN

            New to Lightstreamer: how should I interpret this web request?

            Request:

            The response seems a kind of Javascript. The LS_window.LS_e function, for example, is native of Lightstreamer?

            ANSWER

            Answered 2021-Mar-01 at 08:44

            The exchange you see is Lightstreamer protocol and only some values are determined by the app.

            This protocol is based on javascript and it is used by old client libraries; for instance, the LS_e function is provided by the client library.

            There are several protocols available to the clients; one of them, TLCP, based on pure text, is public and documented here.

            You can convert each of the columns with lists into str and then drop duplicates.

            • Step 1: Convert each column that has lists into a string type using astype(str).
            • Step 2: use drop_duplicates with the columns as strings. Since you want all duplicates to be removed, set keep=False.
            • Step 3: drop the temp created astype(str) columns as you no longer need them.

            Answered 2020-Dec-21 at 04:40

            After doing few tests with example/skeleton and my own dpdk application I have found that the problem is with using rte_eth_tx_buffer();to buffer my packets to TX queues. I have replaced it with rte_eth_tx_burst(); which will transmit my packets as single packet bursts. However, I guess this could affect my TX performance but I haven't done any performance tests yet.

            I have no idea how fm10k have a problem with rte_eth_tx_buffer();. ( Maybe because of FM10K does not support HW offload for VF? )

            Update:

            I have found my mistake. I have used rte_eth_tx_buffer_init(tx_buffer, 1)) instead of rte_eth_tx_buffer_init(tx_buffer, MAX_PKT_BURST)) which essentially make only 1 TX buffer initialized. I'm not sure how it wasn't a problem on other NICs, but FM10420 certainly did.

            How to download images from a website without the 'img' tag?

            You can use the internal API this site is using to get the data including the image URL. It first gets the list of staff groups using the /settings endpoint then calls the /Search api with all the groupID

            The flow is the following :

            • get the portletInstanceId value from a div tag with attribute data-portlet-instance-id

            • call the settings api and get the groups ID:

            I will get you well on your way. You cannot easily do this just with requests because the site's content is loaded after the main page by JavaScript executing AJAX calls to load more content that updates the DOM. You really need to use a tool such as [Selenium](https://www.selenium.dev/downloads/) that will drive a web browser such as Chrome (or your choice) where you can wait for the elements you are looking for to appear. Even then it is not that straight forward. First, the photos are across multiple pages. The code below only processes the first page. You would then need to drive the browser to click on areas of the page to force the next page of photos to load.

            Once the page content has loaded, I use Selenium's ability to find elements by its XPATH to retrieve all the elements that contain the style="background-image: url('some-value'". I then have to retrieve from these elements the style attribute and from that I have to look for the background-image url specification, which could be an empty string. Finally, I use a thread pool to retrieve all the URLs concurrently using a request Session object, which is more efficient. BeautfulSoup is not used at all. Finally, I do not use a randrange call to generate the name of the file since there could be a collision and you wouldn't want to attempt to store two images with the same name (and certainly not concurrently).
