kandi X-RAY | hcd Summary

hcd is a Go library typically used in Blockchain applications. hcd has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

hcd is a Hc full node implementation written in Go (golang). This acts as a chain daemon for the Hc cryptocurrency. hcd maintains the entire past transactional ledger of Hc and allows relaying of quantum resistant transactions to other Hc nodes across the world. Note: To send or receive funds and join Proof-of-Stake mining, you will also need [hcwallet] HC is forked from [Decred] and [btcd] which are full node implementations written in Go. Both projects are ongoing and under active development. Since hcd is synced and will merge with upstream commits from hcd and btcd, it will get the benefit of both hcd and btcd’s ongoing upgrades to staking, voting, peer and connection handling, database optimization and other blockchain related technology improvements. Advances made by hcd can also be pulled back upstream to hcd and btcd including quantum resistant signature schemes and more.

            ANSWER

            Answered 2020-Jul-11 at 14:41

            As you can see in the dmesg output:

            [ 5.379690] usb 1-1: New USB device found, idVendor=10c4, idProduct=ea60

            Looking that up, e.g. here: https://www.google.com/search?q=usb%20vendor%20id%2010c4

            Tells you that it's a "Silicon Labs" USB device, who also make the CP2102.

            The log does not identify other devices (ignore the linux kernel root hub). So either you have also a CP2102 attached (and the FTDI is not properly connected) or the device you think is a FTDI based device, is not.

            In addition you can identify currently enumerated devices using the lsusb command.

            The automatic loading is usually done by udev or a similar user space daemon/mechanism. A decent explanation can be found e.g. here: https://lwn.net/Articles/740455/

            You should reference that unnested (UNNEST(hits) AS h) instance - which is h in this case - so use AND h.isEntrance IS TRUE instead as in example below

            BigQuery (Google Analytics data):query two different 'hits.customDimensions.index' in the same 'hits.hitNumber'
            Asked 2020-Jan-10 at 23:10

            my goal:

            Count 1 for the session if the following two hits.customDimensions.index and associated hits.customDimensions.value appear in the same hits.hitNumber (every row is 1 session if main query is still nested):

            ['hits.customDimensions.index' = 43 with associated 'hits.customDimensions.value' IN ('login', 'payment', 'order', 'thankyou')] AND ['hits.customDimensions.index' = 10 with associated 'hits.customDimensions.value' = 'checkout' [in the same hits.hitNumber]

            my problem:

            I don't know how i can query two different hits.customDimensions.value in the same hits.hitNumber in one Subquery without different WITH-tables. If it's possible, which I'm sure, the query would be very easy and short. Since i don't know how to query this usecase in a subquery, I use an workaround which totals to 5 WITH-tables. I would appreciate an easy way to query this usecase

            Explanation workaround query:

            Table1: Queries all except the 'problem-metric'

            Table2-3: Each table queries one hits.customDimensions.index with associated hits.customDimensions.value filtered for the correct value, sessionId and hitNumber

            table4: left join table 2 with table 3 based on date, sessionID and hitNumber. Basically if hitNumber combined with sessionId from table2 and table3 match I count 1

            How to upload file in hybris backoffice without uploading it to Media?

            I want to create a custom widget in hybris backoffice, which would allow importing CSV files from disk, and the data from the CSV file will be used to insert data into the database. However, from what I've found, hybris allows to upload files only from its Media container.

            Verilog DUT System Verilog testbench: output to wire assignment 1s replaced with Xs
            Asked 2019-Sep-18 at 23:27

            I've a Modelsim testbench in System Verilog testing a Verilog top-level module (ufm1) with another Verilog module (wishbone) used inside it, there's also a System Verilog "stub" (wishbone_sim) that is connected to the DUT in the testbench.

            The DUT and the inner module were originally in System Verilog and worked fine but I had to convert them to Verilog to be able to use Diamond LSE (leaving the testbench in System Verilog)

            The inner module inside the DUT has an output which I'm connecting to a wire (was originally a reg in the System Verilog version because it gave an error otherwise) inside the DUT and then using the wire to assign to a reg in a procedural block inside the DUT.

            Inside the inner module this output is basically assigned directly from an input.

            Now when I'm simulating this the input in the inner module is fine but the output (should be the same because it is a direct assign) is different with Xs in place of 1s.

            The issue only starts appearing when the output of the inner module (rd_data) is assigned to the wire (wb_rd_data), which looks strange to be because I don't see how connecting an output port to a wire would affect its value.

            The wire inside the DUT is wb_rd_data wich is connected to the rd_data port of the inner wishbone module.

            How do I fix this?
