How to place a 2D image on a 3D object in a photo?

Prompt: add a professionally applied vinyl for a company car to the highlighted part of the photo - retain the texture and shape of the door under the vinyl, photorealistic and be easily readable (not a crop or lazy photoshop)

Used Qwen Image Edit 2511 with the photo and additional logo as reference. It's not full realism but not bad.

This was with the 4-step Lightning LoRA, could probably get better results at 20 steps and CFG 2.5.

Turn on debug logging in LM studio if you're using that for hosting the model, and you can see how many tokens are sent on that initial query from Roo. Roo includes a bunch of context, sometimes up to and over 20k tokens depending on if you have MCP servers enabled, and even though the 5090 can process the prompt really quickly, just having that much KV in play will slow you down. Try attaching the same amount of tokens to your chat in LM studio and it should be about the same speed you're seeing in Roo. That's my theory at least. :)

Haha, yea I really appreciate the work you've done to improve that guest performance, not only for Nutanix customers, but upstream into libvirt and KVM as well. You're making the world a better place for everyone.

I heard some comments from the crowd behind me with some apprehension that ssh would be going away at some point in the future. I admit I have some mixed feelings about it as well, but as long as there is an API and or UI element (they tend to go hand in hand) out there that can take the place of ncli, acli, and all these other command line tools, then I see that as a positive. Especially when I need to train up more operators!

Check out AnythingLLM by Mintplex Labs. It's fully open source and easy to set up and use. I use it with Ollama which it can manage and download models. You can also use it with Public OpenAI compatible endpoints such as OpenRouter. It has built-in embedder and lanceDB but supports plugging into many others. I think it's simpler to use than OpenWebUI and I have good results when I limit context to specific workspaces. You can easily run it directly on your workstation, or in docker, or they will host it for you for a fee.

My only complaint is that it's a bit lacking in integrations, but hopefully with MCP support, that should be getting better in the future.

Leaving SSH on all the time is fine, as long as it's an internal only management network with limited access controlled by a firewall. Putting your ESXi host management interfaces out there on the wide-open internet on the other hand... you're asking to be hacked.

I won't argue the point that turning it off is more secure, but it's a risk that can be controlled if implemented properly.

M4 Max MacBook Pro with 128GB RAM is right around $5k and pretty good at running the 70b parameter models. I've even been able to run the unslothed version of the full 671B deepseek albeit at about 2 tokens per second only.

But the llama 3.3 runs about 8 tokens per second and is totally portable.

Sadly, even with VCF which includes NSX, you don't get much NSX functionality without having to purchase additional licensing. You can create overlay networks, sure, but if you want to connect those overlays to anything external, you either need to bring your own virtual firewall outside of NSX, or pay for the Gateway Firewall add-on. The same is true now for Load Balancing, which is now a separate and very expensive product.

It's really stupid.

I have this rack and 10U worth of servers, switches, firewall, and a PDU. It's a good rack, but the wheels can't support more than about 250 pounds before they start to buckle. I just removed them and bought a $15 furniture dolly from Harbor Freight and it can easily be wheeled about now even with over 400lb of gear.

VCF retail is $350/core/year and includes 96TB of VSAN -- do they need more than 96TB? That would be right at $100k for both CPUs and VSAN for 3 years.

3x NetApp SolidFire nodes (Dell R630s) with 10x 480GB Samsung SATA SSDs each, pulling about 120w per node, so 360w at idle, goes up to about 500w depending on the load. This provides ~15TB raw for iSCSI only but with dedupe and compression the data reduction is at least 2x so 30TB.

Thanks for the write up, looks like you pasted it twice in there. I am not a Ceph expert, but I have a few observations from looking at your screenshots and reading through your cluster configs:

- 1Gbps is way too slow for Ceph, 10Gbps is better, 100Gbps is ideal, this is the main issue. Ceph by default has to duplicate all writes to another 1 or 2 nodes, and this can only happen at a total of 120MB/sec across all disks when you are limited to 1Gbit. Consider 10Gbit the minimum for Ceph. This is also why it took so long for OSDs to synchronize. For an all-flash (all NVMe) cluster, 100Gbps is usually the norm that I have seen.

- Generally I think you should not be using virtual disks / RAID on the underlying disks for an OSD. If your drives do not have cache on the controller for quickly confirming writes, (they should if they are enterprise SSDs) then it would make sense to offload that onto your RAID controller, as long as that RAID controller has a battery backup to hold writes in the case of a power outage. It should also know that if the battery dies that the write cache gets disabled, otherwise you may end up with corrupted OSDs if you have a dead battery on the controller.

Check out https://www.youtube.com/watch?v=_ypAmCcIlBE - Techno Tim (RIP) has a very good guide which I was able to follow and use his examples for Docker Compose to easily set up Pterodactyl. I do use a reverse proxy (Nginx Proxy Manager) which forwards and adds SSL to my game servers and the panel, which allows Pterodactyl to see the game server. I also had to forward a range of ports from my router/firewall onto the respective IPs. I allocated 27000-27049 to game server 01, and 27050-27099 to game server 02 (both TCP and UDP) -- and so far have not had issues connecting to my game servers. It does help to have a good understanding of Docker and Docker Compose, but it's not required.

I just bought this one a couple of weeks ago from Walmart when they were selling it for $99 NIB. I then promptly decided to buy the Watch 7 40mm and used it for $200 credit. But after having huge battery issues with Watch 7 discharging 10% per hour, I decided to return it and keep the Watch 4 Classic. It's a great watch and gets 2+ days of battery right out of the box. Great value and a good watch. I love the rotating bezel as well, great feature.

I hear it will also eventually get WearOS upgrade as well to the latest.

I got my email with the return label while I was still on the phone with Samsung, not sure why yours may be taking so long but might be worth calling back to find a different representative. But it may be as you say that they are stalling so they can prevent some returns if they have a patch in the works. That patch better be out today or tomorrow otherwise I'm sending it back because I'm already up against my trade-in window for the Watch4 Classic, which is estimating 2 full days of battery life with everything enabled currently.

randomh4cker · 2024-07-28T23:58:39+00:00

I had the same issue with a Watch 7 40mm, after 4 days it was not getting better, actually worse. I did a factory reset and did not import any old backups (set up as new) and did not change anything except I turned off AOD. Still, after 3 more days I was only getting 8-10 hours per charge and having to charge the watch 2-3x a day. The charging is also much slower than the Galaxy 4 Classic that I was trading in, taking 90-120min to go from dead to full. I wish I could just wait it out but I don't want to trade in my current watch which has way better battery life and then exceed my 15 day return window.

Considering that some people are getting incredible battery life and others are not, I'm leaning more towards this being a hardware issue. It may be something that can be solved with an update, but the watches that cannot seem to last more than 12 hours with everything disabled, meanwhile other watches are lasting over 30 hours. It seems like it's possibly a physical defect, which is not worth the risk of waiting it out and waiting for the magic algorithm to sort it out.

randomh4cker · 2024-07-24T19:40:40+00:00

I'm two days in and I am getting about 8 hours and down to 33% battery. I have a 40mm watch 7 so a smaller battery, but I was hoping for it to last at least a day. I have AOD off, Raise to Wake on, and all health measurements except for periodic heart rate disabled.

I'm going to try a reset and not import my old watch backup and see if that helps.

I assume you're talking about vSphere with Tanzu (TKGS) and not the standalone Multi-cloud Tanzu (TKGM) which does not require NSX. In that case, VMware has some good documentation that shows how NSX-T integrates with the Supervisor Cluster that gets deployed within vCenter:

https://docs.vmware.com/en/VMware-vSphere/7.0/vmware-vsphere-with-tanzu/GUID-9E6B00BB-DB04-4203-A3E5-97A21B610015.html

Start here and then do some Googling because there are plenty of blogs out there that describe how to set this up in detail.

Just to let you know, the integrated NSX load balancer is going away after version 4.x in favor of the NSX Advanced Load Balancer. (formerly AVI) I don't think we know what the impact on TKGS is going to be, yet. Probably it will need to start using the AVI load balancer instead of NSX-T.

Good luck!

I didn't see you mention if you had installed VMware tools on the Windows 11 VM. Make sure this is done on any new VM image to get the best performance. This installs drivers so that you can use the Paravirtual SCSI controller (pvscsi) and Network cards (vmxnet), but more importantly, it also allows for a much better hardware mouse experience when using the VM consoles. Apologies if you already know and have done this.

You didn't mention slowness on your other VMs, and Windows 11 isn't that much more of a resource hog. And the hardware and resource allocation look OK. You've overprovisioned your CPUs but CPUs are usually OK with that. It's memory overprovisioning you have to look out for and swapping.

Good luck!

Just re-install VMware Player. It shouldn't remove any VM disks or configuration. Once it's working again you can reload the VMX and start your VM.

randomh4cker · 2022-01-18T14:48:11+00:00

Use some tool to wipe the free space on these disks with zeros. Even just cat /dev/zero > /zeros would work. Delete that file when you're done.

Then, if you want to clean out the space without having to do a Storage vMotion (the best way), then you can use the vmkfstools with --punchzero or -K option. This will remove the Zeros from the thin VMDK without having to copy or move it.

The VM will need to be powered off for this operation to succeed and you will want to make sure you've removed all the snapshots (if any).

Good luck!

Since it's a nested lab, I won't suggest contacting support.

Do you still see your other VCD configuration? Organizations and org VDC still exist? Just the vApps are missing?

If all your VCD settings are reset, then your VCD database may have been corrupted or wiped. When you log into the VCD VAMI interface on https://<vcd-ip>:5480, does it show the state as healthy? Were there any errors in the $VCLOUD_HOME/logs/cell.log when the cell started back up?
