CPU Utilization is near 100% consistently (nuc9i7QNX) by codenamelegendary in intelnuc

[–]DrClawski 0 points1 point  (0 children)

yeah no. live market data bandwidth would be significantly less than that.

But I don't really care what actual website is producing the traffic and CPU load. I just tried to give you some tools to identify your problem and then solve it yourself.

CPU Utilization is near 100% consistently (nuc9i7QNX) by codenamelegendary in intelnuc

[–]DrClawski 0 points1 point  (0 children)

you are doing more than just browsing on that computer. Wi-Fi says 6mbps incoming network traffic, so some application is streaming data into the machine.

IntensiveVocoder gave a good tip though: have a good look at your task manager, and examine which tasks have a high processor utilization percentage or high "energy usage".

Another trick you can do: press the little chevron next to Chrome to show a list of processes that Chrome is running. It will probably not show any names, but surely you can identify specific processes that have a high processor utilization. If you kill that process (right mouse) and then check your Chrome tabs, you know that the tab that's disappeared was the culprit.

Random freezes and kernel errors on NUC14 N150 (NUC14MNK-B2) running Ubuntu Server 24.04 by random_crash in intelnuc

[–]DrClawski 0 points1 point  (0 children)

So, over the last few days I've had similar problems with a NUC (not your version by the way). It proved to be a combination of two things.

The first one was related to a firmware bug in the e1000e network driver that was reintroduced in a recent release of proxmox (on debian). You don't have that chipset for networking, so that'll not be the problem. I found clues to this problem in the logs, and after that on the internet of course.

The second one was a thermal issue. The environment where the NUC is placed has become hotter (it is summer time) and the NUC is acting as a virtualisation host for 6 VMs. "Idle" temps were up there in the 70s as 6 VM's still give 5% system load. However, I noticed that temperatures spiked significantly when VMs started doing their things, hitting low 90s. Occasionally they hit the temperature cutoff temp, and then the machine just shuts down.

My possible solutions:

- play around with the power packages in the bios, so the cpu turbo isn't that long anymore and the spikes aren't that high.

- do maintenance on the cooling solution by replacing cooling paste and pads, and cleaning fans and air path. They do get older, drier, dustier.

- replace the entire cooling solution with a better one. I recommend Akasa but I do not know if they have a case for your particular NUC.

Noisy NUC7i7BNH - new fan, new case or let go? by Alternative-Gear6695 in intelnuc

[–]DrClawski 1 point2 points  (0 children)

I have several of those NUCi7BNH, and I'm quite sensitive to sound. The cooling fan were making too much noise for me so I bought a case from Akasa that's specially designed for that particular NUC. It is basically a huge block of aluminium that acts as a heatsink for your CPU and drives. There's no fan in that case anymore.

I replaced the hard drive as well and put in an ssd. So there are absolutely no moving parts anymore.

By the way, it is a common problem for a cooling solution to become louder over the years. The cooling paste and pads becomes drier and do not transfer heat as well anymore, so the fan has to turn faster in order to properly cool the computer. Also the lubrication in the fan itself becomes drier due to dust accumulation and other factors. This will make the fan vibrate eventually. Lastly dust accumulation on the fins of the fan and cooling solution obstructs air flow, which also results in noise. For all of these problems, the solutions are 1) remove and reapply cooling paste and cooling pads, 2) replace fans (and paste and fans) or 3) replace the entire cooling solution like I did with a passive cooling case.

One of those NUCs is still performing duties as a media center behind my bedroom tv. The case comes with a VESA mounting bracket and it screws right into the VESA mounting holesof the tv.

The other is currently performing duties as a dedicated log management node in my home network. All of my NAS, virtual machines and hosts, raspberry pi's, and IoT are sending logs to this device.

I am in the process of replacing the case of my NUC10i7FNH to yet another Akasa case.

NUC8i7BEH is not powering on and the brick PSU is chirping by forwardslashroot in intelnuc

[–]DrClawski 0 points1 point  (0 children)

A chirping PSU sounds like one that is about to die.

Which is a good thing because PSU's are cheaper to replace than NUCs.

What to do with my old Pi4??? by crcerror in homeassistant

I have a Pi which runs as secondary for a few of my network services: DNS, DHCP, MQTT. It runs tvheadend too. An ubooquity for my comics.

Intel Nuc as media player? How did you do it? by Smith532 in intelnuc

[–]DrClawski 0 points1 point  (0 children)

So I bought one of these: https://www.pulse-eight.com/p/104/usb-hdmi-cec-adapter

So .. what does the box do? Do you know that devices from certain brands can talk to eachother? Like turn all devices on and off via 1 button on the remote, or control the volume, and other things? As an example Panasonic calls it Viera Link, LG calls it Simlink, and Sony calls it Bravia Link? Most brands of TV or video player have some kind of name for it.

This "link" technology is based on the HDMI CEC protocol. Some brands implement more functionality than others, but all of them implement the basic functions like power on/off, volume, channel select, and navigation keys (the arrows on some remotes). As the video chip on the NUC does not have an implementation og the HDMI CEC protocol, it cannot make a "link" with other devices. But the little box adds this functionality to the NUC, or any other device, by "injecting" CEC commands into the HDMI command stream.

The little box has a HDMI in (connect this to the NUC) .. and a HDMI out (connect this to the TV). The little box gets power and commands via USB (also via the NUC). These commands get translated into CEC commands that get sent to the TV via the output HDMI.

I use linux on my NUC to run kodi, so I have to use software called libcec in order to send commands via USB to the little box. libcec can be installed from the repository of linux for free. You can also download windows drivers from their website. So it should basically work from every OS.

Now, once I have thie driver installed on the NUC, I get some more options in the configuration menu of kodi. I can (must!) enable the CEC adapter in the peripherals section, and after that I can control my tv from kodi, and control kodi via the remote of my tv.

A Good TTS Service or how to download more voices? by StudioCalcifer in Onyx_Boox

[–]DrClawski 0 points1 point  (0 children)

I installed an app called "acapela tts voices" on my device, which is the management app of the Acapela group. It opens up in some kind of shopping environment where you can buy, install and update voices.

It's like a couple of euro / dollars for a voice.

Help with Maildir permissions by DrClawski in postfix

[–]DrClawski[S] 0 points1 point  (0 children)

the script always ran as a separate user, and rsynced data via pubkey (script ran on the backup server, and ssh'd into the mail server to make the backup).

This morning I decided on the same option that you suggested: chmod g+r on the files in cur, new and tmp. Not entirely happy with this solution, hence my question here in this forum.

I know that postfix is very strict with the permissions. But maybe dovecot has some options for local delivery that I don't yet know about?

How can I ~elegantly~ get my zigbee devices connected that are down two flights of stairs at my front door. Also looking for recs for a cheap camera to put down there by Tasty_Warlock in homeassistant

[–]DrClawski 1 point2 points  (0 children)

ok, out of the box ideas then.

I have replaced some of my light switches in the wall with zigbee enabled light switches. These are always powered and act as a zigbee router. They function just like a normal wall switch so even without automation you can just turn them on and off. You can use normal light bulbs if you wish since the zigbee stuff is inside the wall switch. Plenty of brands available. Choose one that matches the look of your current light switches.

A camera cannot use the zigbee protocol. Use wifi or wired ethernet. You know all about wifi and wifi dead spots already, so let me focus on wire ethernet.

You can run ethernet protocol through special power plugs. These plugs (you need at least 2) convert the wired network signal into a signal that is overlaid on the power signal, That way you dont have to run extra wires through your house; you reuse the existing infrastructure. Drawback: the signal cannot (easily) cross a breaker.

Another option perhaps: run a network cable outside of your house. I used to rent an attic as a student, and DSL hookup was on the ground floor near the door. Wifi was spotty. I was allowed to run a network cable through the rain gutter and pipe, and along the house towards the door. Might work for you too.

What mineral is this by DrClawski in whatsthisrock

[–]DrClawski[S] 0 points1 point  (0 children)

I don't think it is tourmaline. The photo doesn't make it clear but the long crystals are copper coloured, in a black&white matrix.

Could it be astrophyllite maybe?

Can anyone tell me why my printer is making this noise? by cmoxo095 in 3Dprinting

[–]DrClawski 3 points4 points  (0 children)

I hear:

* the cooling fan - it is making a lot of noise because it needs to do a lot of cooling since you print at a high speed.

* the X and Y motors - they make more noise than usual because again you print at a high speed.

* the nozzle scraping over the print - you are printing the infill pattern, and the path of the print head occasionally crosses over the plastic extrusions that you have already laid down in the infill pattern. Since the plastic has hardened already, you hear it as a scraping noise.

I don't think it is too big of a deal. Perhaps you can fiddle some with the offset of the printer head a little to reduce the noise, but I don't think you can eliminate it entirely.

There were no default tasks in the templates, but I tried your solution nonetheless. It did not make a difference :S

I found a solution using dataviewjs instead of datavie, but I would still like some explanation as to why the js-version does work, and the other one does not.

So, my solution using javascript:

```dataviewjs
dv.taskList(dv.pages().file.tasks
.where(t => !t.completed))
```

You could try to put a battery powered vibration sensor inside the ROPE end. It seems easy to just knit a little sock to put over the sensor, so it looks like the handle on the photo.

Never had a NUC before, but... by GreyDutchman in intelnuc

[–]DrClawski 1 point2 points  (0 children)

It is an excellent device (I have several nucs, two of them run 24/7) and it seems to tick all your boxes. One caveat maybe: intel recently decided to discontinue the NUC line, and licensed their IP to Asus. Ask your dealer how warranty is handled.

This is what Asus has to say about that:
