GMT to PST conversion and GMT to DST conversion
Did you make up your own time zone region? There is no place in the world where daylight saving is from the first Friday in March till the first Monday in November.
Other than that the question is trivial - use the at time zone operator, like below. Note that I use a timestamp literal for the input, but you could use any expression that evaluates to a timestamp in the 'GMT' time zone (or in any time zone for that matter). Note that 'America/Los_Angeles' follows the PST/PDT model, but not with the dates you indicated in your question.
select timestamp '2020-10-29 01:30:00.000 GMT'
at time zone 'America/Los_Angeles' as pst_pdt_time
from dual;
PST_PDT_TIME
-----------------------------------------------
2020-10-28 18:30:00.000 America/Los_Angeles PDT
Time zone PST and/or PDT are ambiguous, see
SELECT tzname, tzabbrev, TZ_OFFSET(tzname)
FROM V$TIMEZONE_NAMES
WHERE tzabbrev IN ('PST','PDT')
OR tzname IN ('PST','PDT');

I'm using elasticdump and got weird error

--input-index is for a different use case.
Try with just --input like this
elasticdump --input=http://localhost/dev_index --output=test2.json
I'm currently building a versioning pipeline that would automatically promote tags based on date. I am able to return all my tags with this command: git for-each-ref --format="%(refname:short) | %(creatordate)" "refs/tags/*"
Which outputs something like this:
v1.0.0 | Mon Jan 24 14:36:19 2022 -0600
v1.1.0 | Mon Jan 24 14:37:06 2022 -0600
v1.1.1 | Mon Jan 24 14:40:39 2022 -0600
v1.1.2 | Tue Jan 25 17:47:32 2022 +0000
v1.1.3 | Tue Jan 25 21:20:03 2022 +0000
v1.1.4 | Tue Jan 25 21:22:40 2022 +0000
v1.2.0 | Tue Jan 25 21:24:08 2022 +0000
v1.3.0 | Tue Jan 25 21:52:28 2022 +0000
I'm looking to take this output and filter it based on current date. So for example if I want all tags created after Jan 24, I'd need to filter this output to only return the tags created from the 25th and beyond.
I'm thinking awk could help with this but I'm uncertain.. Any tips would be great!
This bizarre thing has just started happening on my Mac which I don't understand. New .png files copied into ~/Desktop are being deleted within 10 seconds of being placed there.
It doesn't have happen with .txt files. It doesn't happen with .png files that are actually text files. It does happen with .txt or .bin files that are actually .png files (by contents). It doesn't happen with any files that are copied into subfolders of the Desktop.
The Desktop is linked to iCloud, but always has been. I haven't changed any iCloud related settings. I have DropBox installed in a different account on the same machine, but that account in not logged in and DropBox is not running.
Can anyone explain what is going on and why it just started happening?
Here is the test script:
#!/bin/bash
do_it() {
date;
cp $1 Desktop/;
count=15;
while test $count -gt 0 && sleep 1; do
let count=count-1;
echo "$(date) $(ls Desktop/$(basename $1))";
done;
}
run() {
for n in desktop.png desktop.txt desktop.zero.bin desktop-png.bin desktop-png.txt; do
do_it Documents/$n
done;
}
run
And here is the output - notice how files that contain .png content are been moved or deleted by something but text files and binary files that don't contain PNGs are not being moved or deleted.

Update: thanks to Joseph I installed this simple audit tool and discovered that it is the "bird" process renaming a file. This "bird" process is associated with iCloud and sure enough when I look into the restored files page on iCloud I can see the files that are disappearing.
So, the next question is: why iCloud doing this and how do I tell it to stop?
I use an apache storm topology on a cluster of 8+1 machines. The date on these machines is not the same and we may have more than 5 minutes of difference.

Question:
Is the storm topology affected by this non-synchronization?
Note: I know that synchronizing is better, but the sysadmins won't do it without proving them proofs/reasons that they have to do it. Do they really have to do it, "for the topology's sake" :) ?
Thanks
It depends on the computation you are doing... It might have an effect on your result if you do time based window operations. Otherwise, it doesn't matter.
For Storm as an execution engine it has no effect at all.
I installed MongoDB through home brew on osx lion but for some reason, it keeps starting up automatically when I login.

How can I remove this from starting up automatically? I don't really use mongo a lot so its kinda not needed and when I do need to use it, it's kinda annoying to get an error when I try to fire it up :/
It should be either:
launchctl unload -w ~/Library/LaunchAgents/org.mongodb.mongod.plist
or
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
