1. The lounge is for the CodeProject community to discuss things of interest to the community, and as a place for the whole community to participate. It is, first and foremost, a respectful meeting and discussion area for those wishing to discuss the life of a Software developer.
The #1 rule is: Be respectful of others, of the site, and of the community as a whole.
2. Technical discussions are welcome, but if you need specific programming question answered please use Quick Answers[^], or to discussion your programming problem in depth use the programming forums[^]. We encourage technical discussion, but this is a general discussion forum, not a programming Q&A forum. Posts will be moved or deleted if they fit better elsewhere.
3. No sys-admin, networking, "how do I setup XYZ" questions. For those use the SysAdmin[^] or Hardware and Devices[^] forums.
4. No politics (including enviro-politics[^]), no sex, no religion. This is a community for software development. There are plenty of other sites that are far more appropriate for these discussions.
5. Nothing Not Safe For Work, nothing you would not want your wife/husband, your girlfriend/boyfriend, your mother or your kid sister seeing on your screen.
6. Any personal attacks, any spam, any advertising, any trolling, or any abuse of the rules will result in your account being removed.
7. Not everyone's first language is English. Be understanding.
Please respect the community and respect each other. We are of many cultures so remember that. Don't assume others understand you are joking, don't belittle anyone for taking offense or being thin skinned.
We are a community for software developers. Leave the egos at the door.

Yep,
Just a sensational article title.
There's no new physics here. Here is a video of an ice skater changing shape[^]. Video makes it easy to understand conservation of angular momentum. The experiment in the article confirms the existing prediction that changing shape (and angular momentum) in curved space can be used for locomotion.
It's the experimental setup and accurate measurements that's really a breakthrough. The setup they are using to make these measurements reminds me of the old Foucault gyroscope[^].

No, no, no!
You got this completely wrong:
Quote: They then connected this system holistically to a rotating shaft
and Quote: These forces hybridized with the curvature effects
Do you know how dangerous it is to hybridaze the forces with the curvature effects, specially when they are connected hollistically?
Just one more that had me scratching my head:
Quote: the slight frequency shift induced by gravity became crucial to allow GPS systems to accurately convey their positions to orbital satellites
What frequency? What GPS systems?

It took me a few minutes to realize that you were quoting the article here:

You should contact the U.S. Department of Defense and let them know! They paid for the experiment under contract W911NF-19-1-0056

(nobody actually said that. probably ever)
Looping MIDI performances creates a number of interesting challenges. For starters, you have to count the number of times note offs and note ons happen so that the note offs you've captured in a loop do not cut the notes you're actively playing short.
Secondly, you have to insert note offs for any note that's currently being held down when the loop is finalized *but* you avoid sending the actual note offs, you just insert them at the end of the loop for the next time around.
Finally, you have to quantize the loop lengths so you don't have to have the timing of a 12-year old gamer to actually play the thing.
And and there's gotchas, like not capturing MIDI reset messages, or pitch bend messages.
All that is ignoring the user interface, where you have to set up which midi signals you use to indicate the start and stop of a loop, and how to navigate multiple loops. It gets hairy fast.
It's an interesting challenge though - one I solved ages ago purely in software as a VST plugin but I've long since lost that code.
To err is human. Fortune favors the monsters.

She's been having issues with low blood pressure causing fainting, and last night she started having chest pain. Took her to the hospital around 2:30 PM, and went home an hour or so later to let the dog out. I got a call from her a bit ago, and she's been admitted for monitoring overnight due to damage on her heart and elevated cardiac enzymes (at 58, normal is < 10). The doctor is going to do a cardiac catheterization in the morning, and go from there.
What do you get when you cross a joke with a rhetorical question?
The metaphorical solid rear-end expulsions have impacted the metaphorical motorized bladed rotating air movement mechanism.
Do questions with multiple question marks annoy you???

![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif) I wish her (and you) well. Elevated enzymes are usually a signal of a recent infarction. Good that she's getting immediate intervention.
A few weeks ago one of my crew (female, 70s) at the Fire Control Centre said quietly "Peter, I'm not feeling well." Did the obvious checks, called an ambulance. Paramedics did an ECG, nothing obvious. BP all over the place. Took her to the local hospital for further tests. Wound up staying for 3 nights until they could get meds sorted to manage her BP.

That doesn't sound good. I hope she comes through OK.

I recently bought a new 14TB disk drive to put in my new 4-disk enclosure (no raid or anything special, just a simple enclosure to save power strips) connected to my file server via 6gb eSATA.
I liked the way it performed so went back to buy another one only to find it was out of stock but they offered a "renewed" version of the same disk for $10 less. I decided against this as disk life seemed important and I don't care how much they polished the case, the disk itself had obviously done some amount of spinning before it was "renewed".
Anyone got any definite knowledge or even vague opinions about this?
- I would love to change the world, but they wonβt give me the source code.

Use the renewed one as a backup / for backups of the new one (or vise versa).

$10 off on a $300 dollar HDD to get a used drive? I'll give it a miss.

HDDs are assembled in a clean room (How it's made - Western Digital Hard Disk Drives - YouTube), because even dust particles can cause damage to the platters or R/W heads. There is no guarantee that the "renewal" work was performed to the same standard.
Note that some HDD manufacturers will sell refurbished drives. These are typically repaired drives that have been tested by the manufacturer to meet the same standards as new drives, and are typically sold at a significant discount. Going to Western Digital's website, a MyCloud Home 8TB lists for US $299, while a refurbished device lists for US $199.
Personally, given the relatively low price/TB of new HDDs, I would not risk my data on a drive that has already failed once.

^ This.
Why else does anyone return a drive?
It's a ticking timebomb. I would not use a drive for anything important. That includes using it as a backup drive, as someone above suggested. Why would you back up anything on a drive you'd have less trust in than a drive for your "live" data??
Unless it's purely as an additional backup set.

Sadly, my old NAS fried a disk port, and that fried a disk, or a disk fried itself and that fried the disk port - but since Seagate made all the disks and the NAS itself, it's a moot point which did which.
Certainly the disk from port 2 is dead, and if I plug anything into port 2 the whole NAS locks up solid. And somehow, that destroyed the whole volume at the same time so all my info is toast. Never mind, I have the important stuff on offline archives, but I've lost all the JPG, MP3, and MP4 I loaded on from phones, CD's and DVDs over the years.
So, I've replaced the disk with an identical one to keep them the same, and bought a new NAS - QNAP TS453 this time. It's currently building the RAID volume which'll be a while longer as 16TB of disks is a time consuming process even at 6Gb/sec.
But test writes even while it's doing that show it's about 4 times faster write speed than the Seagate, and that should improve once the volume is complete.
And it supports SMB3 so Windows likes it!
But it can do other things: LDX and Docker containers ... including SQL Server as supplied in Developer Edition 2019 by Microsoft. 
That could be well worth putting on ... anyone got experience loading a docker SQL/Linux combo? (I know, I know - linux is the devil's OS but I don't have to touch it once it's running and it'll export it from my dev PC).

I have a 9 year old Synology NAS with 4TB of mirrored drives. In the last couple years, I've moved most stuff to the cloud and archived the remainder to external USB drives. When the NAS dies - I'll unplug it and forget it. Life is too short to manage home networks.

FTFY.

Yep. 8Mb/s upload vs 200+MB/s write speed? Not a contest.
Even with the Seagate, I got 35MB/s writes.

To each their own. I analyzed my usage and decided the cloud was a better choice.
Just curious⦠what kind of big data files are you transferring so frequently that makes local network storage so important.
