@DustinB3403 maybe it's also helpful to know that Jupiter's axis of rotation is roughly 3 degrees compared to Earth's 23.5 degrees. But we would see Jupiter at any angle depending on when we look at it.

RE: Astrophotography
@DustinB3403 No, it depends on where Jupiter is in the sky, where Earth and Jupiter are in their orbits relative to each other, Earth's rotation/angle, my camera's rotation, and my telescope's positioning.

RE: Astrophotography
Thanks! There's a learning curve for sure, but it isn't bad. Well worth it if it's your thing.
The angle of the image is determined by my camera's rotation. I have mine attached at about a 0 degrees. So when the telescope is in it's zero-position, my camera has no rotation angle (or close). I don't care about the rotation when doing planetary. With DSOs such as nebulae and galaxies, I generally do care about camera rotation for framing purposes.
The part that takes the most time is the processing of the images. It's a whole different world of understanding and practice.

RE: Astrophotography
Some quick fun with Jupiter during the daytime evening before the clouds rolled in, again.
Trying to get back into some planetary work. I have to relearn it, it's been a long long time.
I don't think this one turned out so well, but I think if I redo it later and spend some more time processing and learning, I can get it better. A night-time image would help too.
I think my old one was much better. I spent more time on it and used a tutorial.

@Obsolesce said in What Are You Doing Right Now:
New (to me) telescope arrived today!
Nice, going to use it for photography?
Yes, astrophotography. This is a bigger telescope than I had before. 203mm aperture, 2032mm focal length, f/10 native.
I finally got a chance to test it out for about an hour last night on Jupiter mostly visually. I looked at it at about 6100mm focal length @ f/30. It looked so awesome. I've never seen it that big and clear in person. I hooked the camera up for a bit but didn't go well due to the balcony being so shaky and Jupiter started going behind a tree by that time.
I'm hoping to get some more clear nights soon so I can give it a real go. Clear nights are truly a rarity these days here.

RE: Windows 11 Remove PIN and Only Use Password Instructions
@gjacobse said in Windows 11 Remove PIN and Only Use Password Instructions:
I may have an account I have forgotten about
But I continue to use local only. I believe they call it an “Offline Account”On my personal Windows laptop, I use my Microsoft account (MFA'd). It makes things all around that way more convenient for me. To avoid passwords, and because I want that separated, I use Windows Hello (fingerprint or PIN). Then BitLocker (TPM 2.0+), and of course the BitLocker Startup PIN.
On my personal Linux laptop, basically the same thing as above, but SW level encryption.
I'm looking forward to trying Ubuntu's TPM-backed Full Disk Encryption soon! I haven't had time yet. -

@DustinB3403 said in Define Air Gapped Networks:
When using terminology like "Air Gapped" what is your first impression of it?
When I see someone say they have an air gapped network, I think it to mean that the network is separate from the rest of the organization (through a physical disconnect), and that Air Gapped, does not imply the lack of internet.
Air Gapped != Without Internet
What's your opinion?
An air gapped network is indeed physically isolated from other networks, but the key yiur missing is that it is also isolated from the Internet. The primary characteristic being lack of any connection to outside networks, including the internet.
It's not the "connection to the outside" that violates the air gap, the issue is that if BOTH networks connect to the Internet or any shared network, it clearly isn't air gapped. Air gapped systems can never talk to each other without a different mechanism passing messages in between that crosses the air gap.
You misinterpreted what I wrote. Coupled with the first sentence, it's clear. Also, outside being outside said network, not necessarily public networks.

RE: Options to securely deliver electronic documents?
@JasGot said in Options to securely deliver electronic documents?:
We have a customer that is asking about delivering documents to their customers; securely.
Much like a bank would do it. They send you an email with instructions to visit their site, login, and download your file.
Anyone aware of a service that does this?
What do they define as delivering documents securely?
You'd need to host a site they can log in to, or use something else that requires an account they already have, such as requiring them to log in via a known MS or Google email. For example, send them a link of the doc(s) in OneDrive or Google Drive that requires them to authenticate.
Any other service that does this, you're just trusting that the correct person signs up for that "other service" to access the documents.
It works well for the bank because when your own bank does it, you already have an account to use to sign in and get get the doc.
In the case where a company wants to provide a document to a customer, then it needs to be with a service that the customer already has an account with or is capable of verifying the person before they create one to access it. If the company can, ideally they would make the document available via the service (OneDrive, Google Docs) to that specific customer's email. Then they'd be forced to sign up (if they don't have already) or use that email to access the docs.

RE: Need new webhost
@DustinB3403 said in Need new webhost:
@Obsolesce a 5 day window to try and migrate a bunch of sites isn't unrealistic, but it is a tight timeline to avoid getting billed.
Have you called and spoke with them about the bill and see if they'll do anything to reduce it? Surely they would want to keep a customer vs lose one..
Not concerned about the migration timing and all that. Just concerned about not renewing because I've hopefully found a better option.

Need new webhost
I'm looking for a new webhost to host a hand full of sites, mostly WordPress sites, a couple which are larger and more accessed. Ideally something that offers the same thing or better as the Dreamhost Shared Unlimited plan. The less I have to do in regard to site migration, maintenance, etc., the better.
It feels like Dreamhost is ripping me off like crazy, being a customer for many years, and having to pay 5x more money than if I was a new customer.
I'll be billed in 5 days for another year, but hopefully there's something better?

RE: Debian Bitnami WordPress VM Disk IO Spike Most Days at Same Time and Crippling the Site
1. Identify the Cause of High Disk IO and CPU Wait
- MariaDB Activity: Since
mariadb
is showing high IO during the problematic window, it's crucial to identify the queries causing this load. You can enable the slow query log in MariaDB to capture queries that are taking an unusually long time to execute. - Scheduled Tasks: Check for any scheduled tasks (cron jobs) on the server that run around 5 AM CST. These could be system tasks, WordPress cron jobs, or database maintenance tasks.
2. Systemd-journald Failure
- The failure of
systemd-journal-flush.service
suggests that the journaling system is overwhelmed, likely due to the high IO load. Investigate the journal logs (journalctl
) for any errors or warnings that occur around this time.
3. Review WordPress Plugins and Activities
- Plugin Behavior: Even though plugins like Updraft Plus are scheduled for different times, they might be triggering background tasks. Verify plugin behavior and logs.
- WordPress Cron: WordPress has its own cron system (
wp-cron.php
) that can sometimes trigger resource-intensive tasks. Review the WordPress cron events.
4. Server and Database Optimization
- Database Optimization: Run a check and optimization task on your MariaDB database. Over time, databases can become inefficient and slow.
- Upgrade Resources: An e2-micro instance is quite limited in resources. If this issue is related to resource constraints, consider upgrading the VM instance type.
5. Monitoring and Logs
- Enable Enhanced Monitoring: Tools like
sar
,iotop
, oratop
can provide in-depth system metrics. Make sure they are configured correctly. - Access and Error Logs: Review NGINX, PHP-FPM, and MariaDB logs for any anomalies during the problematic time frame.
6. External Factors
- Traffic Spikes: Although Jetpack stats show low traffic, consider checking the access logs for unexpected traffic spikes, which might be bots or crawlers.
- Network Analysis: Use tools to monitor network activity. Unexpected external connections might be contributing to the load.
7. Testing and Isolation
- Isolate Components: Temporarily disable certain components or plugins during the problem window to see if the issue persists.
- Test in a Staging Environment: If possible, replicate the setup in a staging environment to test without affecting the live site.
- MariaDB Activity: Since

RE: Astrophotography
@Obsolesce said in Astrophotography:
I finally had a clear night since getting my new camera. Although I wasn't prepared for the surprise clear night, I still got out for a few minutes to get a decent shot of M 42 (Orion Nebula) before my portable power unit died.
I'm excited to report that with only less than 20 minutes of data via EAA live stacking, I was able this get this awesome shot in my insanely light polluted area thanks to the L-Pro filter.
This gives me a lot of hope that once I am able to get out there and get a couple hours of data, I'll be able to get something awesome.
Below, M 42, an ad-hoc 18 minutes of data with a blown out core and a satellite streaking across (thanks Elon).
Hoping for some more clear skies in the near future and a trip to some darker skies!
Updating with an auto-stacked photo ~58 minutes of data, and some minor post-processing. I want to stack properly, get some more data, add in some calibration frames. Going to add in here to track progress and compare.

RE: What Are You Doing Right Now
I tried another browser with no extensions, and it worked. It isn't bad aside from the insane amount of ads. If you look past that aspect, it's actually a pretty nifty service. I wish I had thought of it. Though, I'd have done half the ads and would give an option to pay for no ads + 24/7 server uptime.
