I currently have a Lenovo N42 Chromebook far past it's EoL, for which Google is no longer supporting it. I have put Chrome OS Flex on it by reflashing the bios, and it's pretty solid, but I have no internal audio. Bluetooth audio and HDMI works fine, but no headphones, and no speakers.

I found this solution for trying to hack in an Alsa configuration from an Ubuntu Live Disk (https://www.reddit.com/r/chromeos/comments/swzxsy/comment/irk5kqk/) and I was able to follow the instructions and enable development mode, but when I try to run the alsaconfig script, I get this.

crosh> shell
chronos@localhost / $ sudo alsarestore
No state is present for card chtrt5650
/usr/sbin/alsactl: sysfs_init:48: sysfs path '/sys' is invalid

Found hardware: "chtrt5650" "" "" "" ""
Hardware is initialized using a generic method
No state is present for card chtrt5650

It may have something to do with those instructions being for a different build computer, but I am outside my sphere of knowledge, and anything else I could troubleshoot would be appreciated. Internal audio isn't mission critical for me, but it would be appreciated.

I'm a full stack dev and my current use of JavaScript language is limited to making the best (read trivial) use of jquery for DOM manipulation in my web apps which primarily use PHP or Python (Flask/Django) as backend.

Now, have you watched that popular thriller movie called Inception which is based on a radical sci-fi concept that an idea or thought can be implanted into someone remotely?

Just like that, I often find myself facing this strange idea that JavaScript is supposed to be just a toy running inside the web browser. No idea where exactly this idea came from! Each time I try to learn JS or think of getting deeper with things like npm, react, etc., this idea just pops up and kinda stops me from doing anything!

Is there any way to get rid of this idea somehow?

I've always been enticed by 8 bit computer projects like this but I've never bought any because I can't think of anything I'd do with them given their self-contained nature. Even a really primitive ethernet controller would explode the project possibilities. Does anything like that exist?

I'm considering moving back to the Linux world after having jumped ship to Windows around Ubuntu 20.04, mostly due to increasing bloat, snap and other things I don't recall.

I've used Xubuntu in the past, the Thunderbird theme was good but I was disappointed by how little customization was allowed there, even the selection of wallpapers seems bland, especially when I compare it to Mint now. Even when it comes to UX experience, it seems Mint puts a lot of effort in enhancing the user experience?

So how do these two compare in terms of performance? As long as the difference isn't substantial, I'm leaning towards Linux Mint now mostly because of two reasons:

1. Better UX, selection of wallpapers, customizing ability, etc. as described above.
2. Mint is a community project unlike Canonical which is corporate, I like this aspect too.

What is your own preference in this regard and what do you suggest?

Hey everyone!

Sorry if this is a long post, but I've done my research and I would like to make a few questions.

I've decided that I would like to buy a NAS mainly to storage all of my documents, photos and videos, so that, I can access them from multiple devices and also use it to upload important documents to Backblaze B2. Then, I've actually discovered that I can install a few Docker containers and I could use it as a media server (Jellyfin) and serve the content to my Apple TV (neat!).

I considered a QNAP (better hardware for the price) but everyone recommends Synology instead (because of the stronger security and better overall software), but to be honest, I'm not sure what should I get.

My budget would be to buy a NAS (without counting the disks) below €1000. Ideally, €500-600 but I don't mind stretching to the €700 mark, if it is really worth it.

Spoiler alert: I think, it should be the DS920+ (4-bay) or the DS1520+ (5-bay). I think a NAS above 4-bay is better for future-proofing.

Looking here in Germany at price comparators, I could buy the DS920+ for €663 and the DS1520+ for €750. But these prices seem to be at an all-time high :(

Questions & Assumptions:

0. I'm not sure if the price difference of about €100 is worth the premium to get the 5-bay model. There are only two differences between these two models: The 5-bay has one extra slot, and it has 4x 1 Gbe LAN ports instead of 2x 1 Gbe. All the rest is the same. What is your opinion?

1. I've read that if you run a few containers (~10) it consumes quite a bit of RAM (~3 Gb), so it should be ideal to have at least 8 Gb. This is the reason I've said that I think I can only choose the DS920+ or DS1520+. Looking at official Synology resellers, these models, seem to come already with 8 Gb, and they are within my budget. Is my research wrong?

2. These two models, have an encryption engine. I think this is necessary to encrypt my files before sending them to Backblaze, or?

3. A lot of people seem to say to simply pick Synology's hybrid RAID setup called SHR-1 or SHR-2. I would go the easy way here and pick one of those two. Would you think that is a bad idea, and it is better to pick a specific (standard) RAID? I've read about the long long long RAID rebuild that could happen in some situations, and picking the "right" RAID could decrease the rebuild in days (or weeks!!!!).

4. In case, I choose a NAS model with Nvme cache slots, most people say it is not worth it to use if you are not running Virtual Machines and the SSD’s "burn" really fast. I have no interest on VMs.

5. Most people say to pick an Enterprise (Server) HDD instead of a NAS HDD mainly because price is similar in some cases and Enterprise has longer life and warranty. I should also pick a CMR HDD which is helium filled. 5400 rpm would be preferable to 7200 rpm because of the noise. Sadly, all Enterprise HDD's and most of NAS HDD's are 7200 rpm. Is the noise difference that big? The NAS will be in our living room.

6. Is 8 TB still the best cost per Terabyte?

7. I was extremely sad to hear that the Hitachi hard drive division was bought by WD. I've had lots of misfortune with WD drives (and let's not forget the debacle with the SMR and CMR drives) and I would prefer not to give money to them, but, nevertheless, I'm still tempted to buy the Ultrastar drives that belonged to Hitachi. Does anyone know if WD kept the components, manufacturing processes, staff, etc., that made these brilliant disks?

8. Following the HDD topic, what is your experience with Seagate or Toshiba drives?

9. These two NAS models have the same Intel Celeron CPU, which supports hardware transcoding. To be honest, I don't know in which cases would that happen. It seems if I use Infuse on the Apple TV it would never transcode (and instead direct play) because Infuse would do the transcoding in software. Should I take in account that hardware transcoding is a must-have or a nice-to-have?

10. Would you recommend having a CCTV system connected to the NAS? Should I dedicate one entire HDD just for the NVR system? Would a standalone NVR device be better?

11. My last question is: Should I just wait for the new model of the DS920+ or DS1520+? The 20 means it was launched in 2020 (in Summer specifically) and it seems Synology refreshes the model every two years., that means, a new model would be available in Summer this year. Most people say it is not worth the wait because Synology is very conservative in its model updates/refreshes. People are saying that a better CPU will be of course available (do I even need that for my use cases?) and probably upgrade the 1 Gbe LAN ports to 2.5 Gbe or 10 Gbe (10 Gbe I really doubt it). I've read that a 4K stream does not fill a 1 Gbe bandwidth, and you could theoretically have three 4K streams in a single 1 Gbe connection. If all else fails, I could just do a link aggregation of the two ports to be 2 Gbe, or?

12. Anything I'm forgetting? Should I be careful with something in particular?

I know I should buy a UPS too, but I think I'll create a separate post regarding this topic because I would also want a recommendation regarding a UPS for my other devices.

I know that I could actually build my own NAS and use Unraid for the OS. Furthermore, I'm just at a time in my life with too much on my plate (baby and small child) and having something that just works is preferable. When they are older and more independent, I'll have more time to investigate this option :)

Again, sorry for the long post. Thank you everyone!

I finally got around to upgrading my mom’s computer (an Asus laptop from 2015) from Windows 8.1 to Windows 10. I’ve already deleted a few apps she won’t use (e.g., Xbox) and disabled/stopped some unneeded services. What else can I do to keep her computer fast? Particularly interesting in more services I can disable and the best browser/ad blocker combo. Thanks y’all!

Title says it all. Bootstrap+jquery has been my default route and path of least resistance when it comes to web development. Perhaps because I'm coding since a long time and belong to the old school when modern libraries like react weren't yet invented yet?

I had tried to meddle with Angular.js 1.0 back in those days but was soon disillusioned! It was cool and cutting edge but highly opinionated. It tried to do so many things under the hood that I soon quit the effort and the word "Angular" was stigmatized in my mind ever since! I don't know how different today's typescript based Angular is but that stigma or phobia prevents me from even looking at that direction!

React is another cool technology which everyone is talking about and I'm sure it has some merits. But I'm not sure exactly what React brings to my development workflow which jquery doesn't already do. Can you tell me some specific advantages or pros of react over jquery which can motivate me to learn the former and let go of the latter? What should I do?

I'm working on an app idea, it's going to be "API first" in design which means there is a clear separation between the backend and frontend. Former will be accessible through a REST API and the latter can be simple HTML without me having to delve too much on it. The idea is that the end users or clients will write their own front-end interacting with this REST API in future.

Firstly, I want to know where to start. Writing a REST API seems quite easy and simple for me as a backend engineer but I've never implemented a "pure API" app in practice. Do you just validate the headers, do the crunching and return back a JSON response? What all must you take care of here?

Finally, authentication and session handling is something very important here, isn't it? If I make use of session feature in the REST API (like PHP sessions or Django sessions, for eg), authentication will be pretty easier. I don't have to worry about encryption as SSL/TLS would be already doing that for me through the browser. But then what is the downside of this method? Why do so many people use JWT tokens then?

Coming to JWT tokens, is that the only way of encrypting/validating REST APIs, or are there others? My biggest concern here is scaling and performance. I'm willing to implement the most efficient path here, the one that gives the most performance using least resources.

As I recall, about 2-3 years ago I had experimented with what is called the npm install xyz through some tutorials, etc. The objective was to improve my tooling or toolchain at least with things like css/js minification, etc. along with Bootstrap customization. The idea was to then move on to other newer learnings like react, etc.

But I was soon disgruntled by the whole process! Neither bootstrap turned out to be an easy horse to tame, and NPM was like this astronomical universe of packages that keep on downloading into your folders! I soon lost taste of the whole thing and kept using my tried and tested stack of PHP scripts and using stock Bootstrap through CDNs.

But today, I want to give it another shot. Has NPM improved than earlier days? What is the best way to go about building a toolchain using it? Are there any useful guides that make the whole process easier to digest?

I finally decided to accepted that my interest in working and playing with computers and servers is worth to spend some money on. So I ditched my old box in the corner and with it all my fights with my ISP, their NAT, dynamic DNS and all that and got myself a VPS and 1 TB storage solution for less than I would have paid a static IP with my ISP.
Best decicion ever :-)

So I'm getting into Docker a bit, just because it's just so easy to get Nextcloud running. I used native Caddy as a reverse proxy, because if I got this "machine" there I will use it for other things as well, so make it right from the beginning. And I used native b.c I did not yet understand bridge/host mode and installing caddy native seems easier.
Then I fought for one day with CIFS and the nextcloud gui to get the semantics right to get my storage solution accepted as external storage.
Then I set up Jellyfin with Docker because why not. As well through caddy.
Then I fucked something up and was like, fuck it, lets start again this time for real :-P
I wiped my VPS clean (chose ubuntu again) set up and hardend ssh + sudo installed Docker, and then I found out about docker rootless and in the docker docs it's mentioned that it is/might be more secure, so I set up docker rootless and installed all the rest again.
And then I was like, hmm, do these Docker Images/Containers update themself? Like snap did?
It seems not, so I looked for a solution and found watchtower. And now I wasted another day trying to get watchtower to run, and I just can not.

I tried so many variations of the run command now most recently I tried:

docker run \
--name watchtower \
-v ${DOCKER_SOCKET_PATH}:/var/run/docker.sock \
containrrr/watchtower

time="2023-01-20T01:17:41Z" level=error msg="Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?"
time="2023-01-20T01:17:41Z" level=info msg="Waiting for the notification goroutine to finish" notify=no

/run/user/1000/docker.sock exists, I own it, i tried connecting to it through docker -e and containrrr/watchtower --host "unix:///run/user/1000/docker.sock"
I dont now what to try more and I'm at my end with my ddg-fu as well.

And now while proofreading this, I read everything again and decided to try something again and it just worked...

docker run \
--name watchtower \
-v /run/user/1000/docker.sock:/var/run/docker.sock \
containrrr/watchtower

seems like the environment variable was not set. But I'm shure I tried that before and it did not work... ghost in a machine :-)

So thats where I'm at. I have to say it was a lot of fun and doing and learning all that tingled my brain in a funny way :-)

But now I have some questions for my much more experienced Tildes-friends:

• Do I even need watchtower? because I'm not actually interested to connect to my server regularly to do the updates/maintenance.
• Was switching to docker rootless even a good idea? it seemed so reading the docker installation docs, but just now I read the Archwiki and there it seems it has some heavy security implications, so I made the security situation acutally worse by thinking making it better.
• How do I get this watchtower thing to fucking work? (only if I actually need it)

I very much appreciate all further/other advise, tricks, recomendations, questions and discussion as well :-)
