Apache ZooKeeper is a popular coordination system that's used in many open source projects, including Apache HBase and Apache Kafka. Started in 2007, Apache ZooKeeper is written in Java and embeds a consensus algorithm called ZAB (ZooKeeper Atomic Broadcast). Clients access a ZooKeeper cluster via a client library. Apache ZooKeeper includes a C and Java client library, and other unofficial libraries exist for other languages. The Apache Curator library for Java is often recommended to make accessing ZooKeeper safer and more convenient.

            Whether you are using re or regex, you will have to fix your pattern, as it is catastrophic backtracking prone. Atomic groupings are not necessary here, you need optional groupings with obligatory patterns. Also, you need to fix your alternations that may start matching at the same location inside a string.

            Running your code os.system('cls') is clearing the screen before the input is read in the loop. This makes it seem that there is no output is being displayed when it's really being overwritten.

            A quick test can be done to confirm that this is the problem. To do this we add another input read in the game function. like so:

            In order to not get the nested span:

            1. Find the class you want.
            2. Call the find_next() method on the found class, which will only return the first found match, and exclude the nested span.

            According to the documentation (under "Python Versions"):

            As of 9/25/2018 both Python 3 and Python 2.7 are supported when using tkinter version of PySimpleGUI! The Python 3 version is named PySimpleGUI. The Python 2.7 version is PySimpleGUI27.

            So you should substitute PySimpleGUI with PySimpleGUI27 (or switch to Python 3).

            Size mismatch between Python and C struct with default struct alignment/padding

            ANSWER

            Answered 2021-Feb-26 at 10:02

            From the struct module docs:

            Padding is only automatically added between successive structure members. No padding is added at the beginning or the end of the encoded struct.

            You've miscalculated the padding for your C structure - assuming typical structure layout and 8-byte longs, sizeof(data_E2setupRequest_NodeComponentConfigUpdate_t) will be 304 rather than 300, but componentConfigUpdate_s1AP_present actually goes in the space you thought was padding after componentConfigUpdate_type. The extra 4 bytes of padding are actually at the end of the structure, and struct doesn't add that padding.

            Also from the struct module docs:

            To align the end of a structure to the alignment requirement of a particular type, end the format with the code for that type with a repeat count of zero.

            So if you want struct to pad the end of the structure to long alignment, you can add 0l to the end of the format string.

            (Also, bool is 1 byte, not 4 - there are 3 bytes of padding after all the bools in your struct. You could get rid of some of that padding by putting all the bools next to each other.)

            This can be done with summarise. After reshaping to 'long' format with pivot_longer, do a group by 'Input', 'Time' Word', then summarise to create the 'copy_value' based on a condition that if all values are 0 then return 0 or else return the last non-zero value of 'copy_value'

            • I have data files from word recognition simulations with neural networks.
            • The network has a lexicon of 1000 words.
            • The output has 30,000 nodes -- 30 copies of each word at a different alignment.
            • I run separate simulations with each word as the Input (1000 simulations). The output is a 100-step time series like this (here showing 2 Input examples (ark, bark), with 4 of the Copies for each word, tracking only 4 words, and showing only 5 time steps)

            This answer has been rewritten (twice), see the edition log for the record.

            There are two steps to your problem:

              1. find the max values
              1. select the rows that pertain to those max values

            Finding the max value is a simple matter of filtering. However, you might have wanted to select the Input-Word pairs based on the mean/median across all times, instead of the occurrence of the max on a single time. This would be a matter of summarising (dplyr::summarise().

            Once you have the pairs, you simply need to select the right rows. There might be lots of ways, but I chose to use right_join().

            I chose to separate these steps for didactic purpose, but you can obviously merge them into one pipeline.

            Ark was written by Diego Ongaro at Salesforce in 2016. The name refers to Noah's Ark, which is sort of what you get when you place a zookeeper on a raft. Ark was part of an investigation into (a) whether implementing a ZooKeeper server with a Raft library could be substantially simpler than Apache ZooKeeper, and (b) how best to operate large numbers of ZooKeeper clusters with minimal human involvement. Ark turned out to be a lot of fun to work on, so Diego maybe went a bit too far beyond a little proof-of-concept :) .
