@obsolesce Thanks! That scope is a tad bigger than the one I use for viewing, but should be just as easy to setup. Celestron makes a pretty robust mount for a smartphone to take pictures from something like that.

Obviously this will depend on the COVID situation where you are, but find a local astronomy club and go to one of their star parties, then you can look/use several different scopes and figure out which one might be a better fit.

Also, All of the astronomy resellers have really knowledgeable people and are more than happy to answer questions to help you get started.

Most of the images I take (except for really bright objects like the moon) are imaged over several nights and I'm layering 60 - 100+ pictures to make it. For my photography setup, it is a smaller scope so it is a larger field of view of the sky, it has a dedicated astronomy camera on it. I've never actually looked through my photography setup with an eye piece, I just have a computer sitting out with it controlling the mount, focuser, filter wheel, and camera. Its a time consuming process.

If you are wanting to get in to some of the longer astrophotography stuff, the cheapest way to start is with a DSLR, a lens and a star tracker. You can take some pretty incredible wide field shots with just that.

@obsolesce the best telescope is the one that you will use. The biggest urge you need to fight is buying a larger scope as your first. What you want to do is get one that is a small light and you can setup fast.

One that is good for seeing and good pictures are kinda opposite ends of the spectrum. I do astrophotography as a hobby. (https://instagram.com/westtexasastro) I started off doing visual, the scope I started with is an Orion StarSeeker IV 127mm. It came with a motorized mount that points the telescope, once you set it up a couple times you can do it and align it in 5ish minutes. It is good for looking at the moon and planets, but you can see some of the brighter nebulas like The Orion Nebula. I’ve also hooked my DSLR to the back of it with a T adapter, but you could also get a mount to hold your smart phone over the eye piece to take pictures with as well.

Condom reconditioning is the new fastest growth market.

Dell has 1U precision workstations. I'd look at those.

I thought they stopped making those.

They have a 3930 on the product page that is 1U and can be configured with 9th gen Intel CPUs.

Dell has 1U precision workstations. I'd look at those.

You have to use software RAID since NVMe is attached directly to pcie bus.

@pmoncho a friend of one of our customers got hoodwinked by the Crosstalk guys! They sold him some piece of junk that was literally less than a free phone system and billed him $5,000 for the privilege of getting screwed.

From what I remember watching some of his videos he likes to use the PBXact appliances.

@WrCombs said in Collision Domain - In POS:

Just replaced the first switch in the bar a week ago and it didn't help with the issue.

I've seen gigabit switches fail to negotiate speed correctly and had a 10M half duplex link.

Change the port the line from the back to the bar is plugged into on the switches to test out a bad port.

You could also run an iperf test from one of the up front pcs to the server and see what kind of bandwidth you are actually getting to the server.

I would put money on the actual line being damaged somewhere (bad crimp, punchdown)

One port isn't an issue unless you are saturating that one line, also it is all going down to one line when it goes to the server. If you saturate more than the switch can store and forward it drops the frame. It would be odd if that was the case giving the small number of devices running on the network. I would check and make sure the switches connected to each other are both negotiating at the full speed of the switch e.g. gigabit if it is a gigabit switch.

Does the tablet freeze up as well when the other machines do? If so, i would look at the switch in the back as the issue or the line going to the server.

If it is just the front machines, it may be an issue with the line itself, or the first switch in the bar.

On switches you can't have a collision, they are layer 2 devices with queues. Collision domains were a problem back in the day of hubs because 2 devices could send at the same time. Hubs operated on layer 1 and you would split collision domains with a device called a bridge, it would take packets and store and forward them between the collision domains. A switch is just a multiport bridge, each connection on a switch is its own collision domain since the device will store and forward for each segment.

Odds are your issue are a cabling issue, or a bad NIC on the server, or a bad switch/port on switch somewhere.

It also could be a software issue on the server causing the issues.

FreeOTP Authenticator from Redhat is another option.

I believe the ERX will offload some of the processing.

Was about to say the same thing, @JaredBusch beat me to it.

Exchange 2010 I needed to assign the Import/Export role to my user before I could export a mailbox.

Yes, They are an addon to the standard CAL

I like that his profile says 9 years of IT experience

You can click on almost any IP on any screen and it will pop it into a browser window. So if you have rules setup for that, you will be taken directly to the unit's login.

The only thing I can see suited to their described needs in the Unifi is the ability to use the web browser or mobile app to remotely look at what is going on with internet access when users start complaining about the speed slowing down.

Then the IT person can log in to UNMS and see what the overall speeds and such are. If there is a specific issue, they can log into the specific site. But this is a business and this below should not be an issue.

I have a Unifi at home and I use the mobile app to block my kids at night, and can see they are on Youtube, etc.

This is not a feature that should be used in a business. It is a business, not a fucking adult daycare.

I dont think they intend to use as such other than to figure out where the bottlenecks are while they are occuring.

Personally, I dont think there are bottlenecks, I think its the Sonicwall stuff they currently have.

Well, the UNMS will certainly show bandwidth totals by port.

I will be adding my first EdgeSwitch to my UNMS system this weekend. I assuming some per port statistics would also be available there.

It does not yet, just CPU and latency right now. At least from what I have seen.

UNMS is mostly monitoring right now. Very little config can be done from it, however it does centralize device backup configs to a single place.

From US to Italy! Great beer!

The AllDayIPA is pretty good...

Looking for an Edgeswitch 16 10G in stock... Everywhere seems to be out of stock.
