问题 I'm trying to move away from OFFSET/FETCH pagination to Keyset Pagination (also known as Seek Method).

问题 I'm writing a Python script to read a file, and when I arrive at a section of the file, the final way to read those lines in the section depends on information that's given also in that section. So I found here that I could use something like fp = open('myfile') last_pos = fp.tell() line = fp.readline() while line != '': if line == 'SPECIAL': fp.seek(last_pos) other_function(fp) break last_pos = fp.tell() line = fp.readline() Yet, the structure of my current code is something like the

Sub GSeek() With Worksheets("Sheet1") .Range("H18").GoalSeek _ Goal:=.Range("H21").Value, _ ChangingCell:=.Range("G18") End With End Sub And I would like to use a function to do the goal seek like follows. Function fSeek(a As Range, b As Range, c As Range) a.GoalSeek Goal:=b.Value, ChangingCell:=c fSeek = "Ok" End Function However, the code work peacefully and no answer was got in the range c.

问题 the kafka consumer con defined below works perfectly fine when I try to receive messages form my topic; however, it's giving me trouble when I try to change the offset using seek method or any of its variations. i.e. seek_to_beginning , seek_to_end from kafka import KafkaConsumer, TopicPartition con = KafkaConsumer(my_topic, bootstrap_servers = my_bootstrapservers, group_id = my_groupid) p = con.partitions_for_topic(my_topic) my_partition = p.pop() tp = TopicPartition(topic = my_topic,

问题 I am playing a live content (SmoothStreaming) with a set duration in a Chromecast device. Although manifest has a parameter duration, Chromecast doesn't get it (duration: null). I am trying do a seek to forward but Player only seek until 20 seconds later (buffering time). Is there a way to set the duration of a live stream? Or Chromecast doesn't support live seeking? Thanks in advance 来源： https://stackoverflow.com/questions/47031243/chromecast-live-duration

问题 I'm trying to record audio and create a wav file in Google Drive with the Android API. I have a first pass where I write the header with a file length of 0 bytes because I don't know how long the recorded audio will be and I don't want to keep it all in memory. Once the record is finished I seek back to byte 4 and write the length of the file. This works great when using a RandomAccessFile but I can't figure out how to do something using the Google Drive API. https://developers.google.com
