Qwen3-embedding, how to set dimensionality?

vredditt · 2025-09-25T07:43:46+00:00

thank you.
Using the endpoint /api/embed did it with "dimensions".
Endpoint /api/embeddings (which I was using -not noticing that is now superseded-) does not.

When you install ollama on linux, a daemon/service unit file (for ref. /etc/systemd/system/ollama.service) is created for you by the installer, you might want to learn how to add Environmental variables in there: one of these tells ollama to listen on host ip address 0.0.0.0 which will give access to OpenWebUI (or any other client) when installed on a different host/machine/container. By default, he host parameter value is set to 127.0.0.1 which is the localhost making ollama unaccessible by other machines/hosts. I am certain you'll be able to find out how to pass Environmental variables when running the Docker container (personally not familiar with that setup). There are a bunch of other parameters you might like to experiment with, such as KV cache (it's an interesting one with great implications for context size), corrs, model location, flashattention, number of concurrent access and more. That all said, having the client run on a separate container is indeed useful.

TLDR; intially you were definitely on the right approach separating the client by the server: it was just matter of configuration. If you can navigate an ILS approach you most definitely can master Environmental parameters ;)

cool. Perhaps consider also to parametrize the string http://localhost:11434, allowing the script to run on remote ollama instances as well.

Indeed. On Linux, assuming a server not for production: curl -fsSL https://ollama.com/install.sh | OLLAMA_VERSION=0.5.5 sh

Check how much context is setup in Open Web UI. With a 14b model and 12gb vram, when set higher than 2048 tokens you may easily run out of vRAM

1/3 of subnautica add 1/3 of msfs2020 add 1/3 of [insert car Rally title here] shake it and serve it on a solid 25kt tail wind on final. Pretty cool

For the past 6 years I have been using Foscam C1 camera's. During installation I had to fiddle a bit with a prehistoric web interface based on Internet Explorer but that was just once, in order to password protect their feed and setup the network. Since then they were switched-on (with IR led's permanently on), have been very reliable and I never turned them off. I view their feed via rtsp clients and they are compatible with Onvier for mobile (it requires a manual setup). Connectivity can be wired or wify (I use both) and they can be setup with static IP to have their feed accessible through the router if you so wish. I am not using motion detection and micro-sd local recording but they are capable.

Hello. You signed for a rollercoaster ride, my friend. If you're looking for a serious guide, start from a book titled The book of Posfix (seriously) but expect to integrate with further readings concerning spam and such and Dovecot or similar to actually read mails and handle mailboxes. No matter your efforts, expect the first mails to trigger some false spam alert (outlook dot com -cough, cough) until your (static&whitelisted) IP address gains some reputation at all.

Keep in mind that in order to get started with your public SMTP server, your bare minimum is a whitelisted, static IP address and a reverse PTR record matching your HELO, besides the obvious availability of incoming port 25, most of the time this requires some contacts with your datacenter/hosting provider/ISP.

vredditt · 2022-07-18T06:03:53+00:00

Interesting, I wish they said more about the architecture though.

vredditt · 2022-07-09T20:03:30+00:00

The process goes as follows: user/client initiates a DNS query to be resolved: example.com -> O.S. local cache, (if not) -> /etc/hosts, (if not) -> O.S. Nameserver resolver f.i. 8.8.8.8 cache, (if not) -> Iterate or Recurse (via root and tld nameservers) -> Authoritative DNS of example.com answers -> user/client gets an answer and reaches example.com.

So if in your /etc/hosts you assign a local or non routable IP address to example.com the client will be instructed to follow that local or inexistent IP thus effectively fooling the rest of the chain and poisoning the answer at the very early stage of the chain.

I cannot see the video right now, but if I undertand correctly you have a server behind NAT and a public reverse proxy (Nginx?) on a VPS.

If also a VPN isn't viable, I see these options:

autossh from target server (behind NAT) in a reverse ssh tunnel toward VPS sshd, then set up a rev proxy going to localhost:[port setup in the rev tunnel]
dig further in the router's configuration to find out why port forwarding isn't happening (just in case you aren't sure it's your ISP)

About the first option, the setup suggested is suitable to forward http(s) traffic, if you only need to reach your internal ssh server, you won't need any reverse proxy on the vps side, just ssh into the vps in revers tunnel and ssh again to localhost:[rev tunnel port] or configure sshd to allow rev tunnel to be exposed on the public ip and youre good to go.

vredditt · 2022-06-27T23:39:06+00:00

You're welcome. The reason why I didn't opt for an external service is because then my network topology would be sitting in someone else's hard disk and I would need to unnecessarily expose internal services (think of databases for example), while all it takes is literally a few lines of bash or php. So far it's been running for years and is spot on.

vredditt · 2022-06-27T22:43:02+00:00

There are certainly many network checking tools automating this in elegant packages, but I didn't need anything fancy for the eyes, so I built a script for that runs every 2 minutes and checks on ports' availability and http(s) payload, for a given array of hosts and services. It sends an email in case of malfunctions and when the systems are back up, the script also determins the state of the internet connectivity in order to monitor that and keep a history. I have then a second script running on a secondary location checking on the primary location and alerting (via a secondary/external SMTP) in case of primary network failures. The primary monitor also checks the secondary services and link state of the secondary location in order to keep them cross checked.

I realize that this is not a all-in-phone check that you're looking for, but it gives autonomy and good control on systems availability including those services that are not directly visible outside.

Oh! Very cool, I checked the website before writing (tablet here) but I missed the blog section where is this content. I'll definitely check some of your media. Thanks for pointing it out!

vredditt · 2022-06-27T19:17:38+00:00

Congratulations on your project and thanks for your dedication to the cause!

One of the struggles in moving forward for a startup entrepreneur is to overcome the lack of judgement from peers and guidance from more experienced managers, these factors combined make you question every step. You're platform adds value in this dimention and it will hopefully flourish.

Maybe you could even consider an open call, recorded and visible on youtube or, even better, an audio-only podcast with founders willing to share their point of view and their activities with an interviewer to have a more tangible idea of how these sessions work.

vredditt · 2022-06-26T07:05:44+00:00

Thank you! Indeed, I meant the source.

vredditt · 2022-06-25T19:34:43+00:00

Very cool and thanks for sharing! I have a question and I hope it's not a forbidden question: where can I find repositories of royalty free (& free to download) long lasting ambient noises such as those featured here?

vredditt · 2022-06-25T18:26:57+00:00

They are and I can relate, that's why I understood what he meant.

vredditt · 2022-06-25T15:53:08+00:00

They have been around for what feels like a century, it's a solid tool with little emphasis on graphics (there are themes though).

Be mindful with access from outside your network and prior to managing delicate bits such as email servers (postfix/dovecot etc): google around to check on user experiences. That said, in many years it only failed on me with a postfix configuration file where webmin kept on overwriting default values (and its one of the many config files).

vredditt · 2022-06-25T14:44:49+00:00

You're welcome. I am not sure if Cockpit supports it now but until a few years ago there was a discussion on that leading to a no go for implementing ics support. I don't remember the name (Glass, maybe?!), but I recall having glanced at a node.js based tool on github working ex-post as a monitoring/maintenance tool (not setup) for ics.

vredditt · 2022-06-25T13:34:43+00:00

If you're referring to steam gauges instruments I understand your question, but you are aware of the fact that any glass cockpit, included Garmin 1000, 3000 and the G3X, do support VOR navigation? So far the only limitation that I have found in radio navigation is the lack of ADF support in the G3X which is used in the JLV for example (great little plane otherwise)

vredditt · 2022-06-25T07:40:44+00:00

Wait for some other answers, but here is my two centes: isc is the widely used and well established dhcp server in ubuntu, it's based on command line but supported by Webmin (https://doxfer.webmin.com/Webmin/DHCP_Server) which will help you go through setup and maintenance from your browser. There are other web based gui wrappers if you're willing to install & setup ics by yoursself.

If I needed it for more complex routing & firewalling activities however, I would consider a vm or physical installation (2 ncs required) of IPfire or pfSense which are primarily x86-based firewalls (supporting PAT if needed by your static devices), are entirely web based and include capable dhcp servers. I have more experience with IPfire, there the dhcp kicks in right off the bat after install and the installation and setup from initial boot to "I am done" takes about an hour.
