rough estimate of the time offset from GMT from latitude longitude

由 |▌冷眼眸甩不掉的悲伤 提交于 2019-12-09 14:51:23
问题 Is there a way to estimate the offset from GMT (or time zone) from a latitude/longitude? I've seen geonames, but this would need to work long term and we don't really want to rely on a web service. It'd just be used for determining whether to display "today" or "tonight" when giving information to various users so it wouldn't need to be too accurate (an hour or two off wouldn't be bad). 回答1: offset = direction * longitude * 24 / 360 where direction is 1 for east, -1 for west, and longitude is

How to Set Offsett for Smooth Scroll

由 …衆ロ難τιáo~ 提交于 2019-12-09 13:07:20
问题 I have implemented the CSS Tricks Smooth Page Scroll on my site and it's working pretty nicely. However, because I have a fixed nav at the top of the page, when the page scrolls to the appropriate anchor div, the top of the div disappears behind the nav. How can I offset the scroll (about 70px) so that the whole div is shown? I tried doing this: var targetOffset = $target.offset().top - 70; But that doesn't quite work. The page scrolls to the appropriate spot but then it immediately jumps

SVG stroke-dasharray offset not consistent

由 心已入冬 提交于 2019-12-09 08:23:33
问题 I have a series of circles with borders comprised of smaller circles which I will call 'dots'. I am then animating the circles by rotating them with CSS3's transform , each by either 5 or 15 degrees (alternating) more than the last starting with the middle circle not rotating at all. This alternating of degrees is due to the original offset of half of them of 5deg The animation itself works great, but the offset between each dot in a circle is not consistent. This is made obvious when the

深入了解Kafka【四】消费者的Offset管理

1、Offset Topic Consumer通过提交Offset来记录当前消费的最后位置，以便于消费者发生崩溃或者有新的消费者加入消费者组，而引发的分区再均衡操作，每个消费者可能会分到不同的分区。我测试的kafka版本是：0.11.0.2，消费者往一个特殊的主题“_consumer_offset”发送消息，如图： 消息的内容包括： fields content Key Consumer Group, topic, partition Payload Offset, metadata, timestamp 提交到“_consumer_offset”主题的消息会根据消费组的key进行分区，一个消费组内的所有消息，都会发送到唯一的Partition。 2、Offset Commit Offset的提交逻辑其实和普通的生产者往kafka发送数据是一样的。 2.1、Consumer 消费者启动时会为“_consumer_offset”主题创建一个内置的生产者，用于Offset数据的提交。 2.2、Broker 就是将Offset提交当成是正常的生产请求，逻辑不变。 “_consumer_offset”主题会在集群中的第一个Offset提交请求时被自动创建。 3、Offset的提交方式 Offset提交时会有两个问题：重复消费和漏消费。

How to get Kafka offsets for structured query for manual and reliable offset management?

由 我的梦境 提交于 2019-12-08 22:19:20
问题 Spark 2.2 introduced a Kafka's structured streaming source. As I understand, it's relying on HDFS checkpoint directory to store offsets and guarantee an "exactly-once" message delivery. But old docks (like https://blog.cloudera.com/blog/2017/06/offset-management-for-apache-kafka-with-apache-spark-streaming/) says that Spark Streaming checkpoints are not recoverable across applications or Spark upgrades and hence not very reliable. As a solution, there is a practice to support storing offsets

Excel VBA: using R1C1 format, “Application defined or object defined error”

由 ￡可爱￡侵袭症＋ 提交于 2019-12-08 12:52:41
问题 I am trying to create a formula that references other cells, but I keep getting this "Application defined or object defined error". I use R1C1 convention instead of Offset. My Code: Note: This code could be anywhere, I just need it to work. Also, I don't use the code like this. It is used in a reporting tool, but this is just similar code (to what I actually use) sufficient enough to show my problem Cells(1, 1).Value = "5/1/2014 6:30" soiDate = "$A$1" Cells(10, 6).Value = "6/5/2014 14:12"

ASM find offset with code

由 久未见 提交于 2019-12-08 12:41:29
问题 I would like to find the offsets of different methods in test cases I work with. I can find where methods start and end, I look for opcodes RETURN and ARETURN (Im doing so in a class that extends a methodVisitor in the method visitInsn()), but I have not been able to find the offset where those happen in the bytecode. Any ideas? Just in case: I am working with the core API of ASM, I am aware that the tree API could help me find what I need, but the tree API makes everything go slow and use

VBA Search value in column in another column, if not found show which, if found copy offset value to offset imput

由 半腔热情 提交于 2019-12-08 10:54:01
问题 Can you help me make VBA script that will search values cells in column Sheet1 H:H (every row with data), if it finds the value in Sheet 2 H:H, it will copy offset -6 from sheet 1 and paste offset -6 in sheet 2. If it dont find anything it will tell me which values it didnt find. THis is what i have so fare, working but not optimal, firstly i dont get information of the "NOT" Found values, and if it is not found, it will just overwrite and copy that item anyway.

Replacing a specific hex offset in C#

由 不想你离开。 提交于 2019-12-08 09:37:56
问题 How would I go about replacing the content of a specific hex offset in a binary file with C#? To make it more clear, lets say my offset is 0x33347, and the content of it is 06. I would want to change 06 to 17. How do I do this? I have very little experience with hex editing, so I weren't really able to figure anything out myself, I'm kind of lost. 回答1: Using a FileStream, set the Position of the stream to the offset, then write the byte. This will overwrite the current content with what you
