kandi X-RAY | eden Summary
This is just me toying around with some ideas for an open-world sandbox game, primarily as a way to leverage my daughter's Minecraft obsession into something more productive. It contains a simple server, a slightly-working browser client, and not-working-at-all Go and C++ clients. Don't build this and expect it to do very much yet. When there's something actually worth playing with, I'll update the README to reflect that.

QUESTION
I try to put Apache Arrow vector in Ignite, this is working fine when I turn off native persistence, but after I turn on native persistence, JVM is crashed every time. I create IntVector first then put it in Ignite:
...ANSWER
Answered 2021-Jun-01 at 11:11Apache Arrow utilizes a pretty similar idea of Java off-heap storage as Apache Ignite does. For Apache Arrow it means that objects like IntVector
don't actually store data in their on-heap layout. They just store a reference to a buffer containing an off-heap address
of a physical representation. Technically it's a long
offset pointing to a chunk of memory within JVM address space.
When you restart your JVM, address space changes. But in your Apache Ignite native persistence there's a record holding an old pointer. It leads to a SIGSEGV
because it's not in the JVM address anymore (in fact it doesn't even exist after a restart).
You could use Apache Arrow serialization machinery to store data permanently in Apache Ignite or even somewhere else. But in fact after that you're going to lose Apache Arrow preciousness as a fast in-memory columnar store. It was initially designed to share off-heap data across multiple data-processing solutions.
Therefore I believe that technically it could be possible to leverage Apache Ignite binary storage format. In that case a custom BinarySerializer should be implemented. After that it would be possible to use it with the Apache Arrow vector classes.

I scraped the link and address of each property on page 1 of a real estate website into a list. I then convert this list of lists listing_details
into pandas dataframe by appending info of each property as a row (20 rows in total). My code is as follows:

Answered 2021-May-23 at 04:48Currently, you are not appending anything to listing_details
. Your for
loop should look something like this:

I want to copy data from my SQL database to a data lake, in the delta format. I have created a mount point, databases, and an empty delta table. What I am trying to do now, is to run a databricks job with the following parameters:

Answered 2021-May-12 at 12:39So the actual issue was the io.delta.connectors.spark.JDBC.ImportRunner
part. I have copy pasted it from the blog but the actual path should be lowercased io.delta.connectors.spark.jdbc.ImportRunner
.

QUESTION
I have a column named "Trip", in which I have infos such as the hotel, country, and type of trip. The thing is these infos are hand typed, so sometimes instead of typing "HOTEL ABC", the person entering the infos simply enters "ABC", or event "HTL ABC". Also, ABC can also refer to a country.
What I want is to extract all hotel names on each cell. Here's the function I created, but I can't get it to work. (Y2 is the TRIP Column)
...ANSWER
Answered 2021-Mar-26 at 18:47- You are missing semicolons before "CORAIL NOIR" and "LOHARANO" .
- You need to remove the final semicolon after "FRIDAY ATTITUDE" because
IFS expects all arguments after position 0 to be in pairs
and the final semicolon makes Google Sheets think another set of arguments is coming. - You can help yourself out with future troubleshooting by spacing out your function better - eg the following will still work when pasted into Google Sheets:

i'm trying to get metrics from spring boot application inside my prometheus operator: eks: ver. 1.18 kube-prometheus-stack: version: 12.12.1 appVersion: 0.44.0

...ANSWER
Answered 2021-Mar-26 at 14:09The problem is the servicemonitor can't find your service
the problem is your selector in the servicemonitor definition is not selecting the label of the service
solution: change the label of the service definition to be the same as the matchLabeles definition of your servicemonitor like that:

QUESTION
We are updating from Java 7 to new JRE, initially to Java 8.
The same webapp (whether compiled for Java 7 or Java 8) is taking a long time to start under Java 8.
A very simple webapp, just containing a single servlet, is around 3x slower (from 0.5s to 1.5s).
A typical production webapp, with Spring etc, is taking over 15 minutes to start (from 15s previously!).
Taking thread dumps during startup always yields the same trace:
...ANSWER
Answered 2021-Mar-16 at 18:24After a bit of digging I found the issue was in a subclass of URLConnection we are using for executable war support: JarJarURLConnection (from https://github.com/robo-code/robocode/blob/master/robocode.host/src/main/java/net/sf/robocode/host/jarjar/JarJarURLConnection.java)
It seems that under Java 8 some of the time URLConnection.setUseCaches
is called with false
and this causes the jar to be copied/extracted again and again (and again). I simply overrode this method with an empty body so that the default true
is always used. Since the files are all local I see no reason to not use the cache always.
