      Alright, time to ask for help. I designed a website for my cousin using Wordpress, hosted via BlueHost. It's 99% done.

      The problem: she'd originally registered her domain through wordpress.com. She also has an email through that, which she accesses via Google Workplace. We've transferred the domain, but the nameservers are still registered to wordpress.com. I've found the guides for transferring nameservers on BlueHost and wordpress.com, but this is a step above what I've dealt with in the past.

      My main concern and frustration are the email. She's already using it for work, and I want to make sure there's no downtime, but I... honestly have no idea how it's even set up, right now. Or how this would work when transferring hosts entirely. Attempts to search it haven't been too helpful for me.

      So my questions: How will changing nameservers impact the email? Would updating them potentially just... break her email entirely? Need her to set up the email separately? And if she does, can it be kept through Google Workplace/Gmail since that's what she's already using? Is it fine to leave it as-is? I assume not but her wordpress.com account shows that it expires in 2027, so...?

      Just, please help.

    2. Reverse-Proxying services both inside and outside of Podman

      Hey all, not-a-networks-guy here.

      I've currently got an rpi set up running pihole natively (not in a container) for ad and website blocking reasons. (Using port 80, no TLS) I've used the pihole localdns feature to set an internal hostname for that ip (me.lan).

      On the same pi, I have podman "set up" to run FreshRSS, and I'm getting more and more annoyed about using the port # to access it. (me.lan:12345) I'd like to set up a reverse proxy (probably Traefik) in a container to redirect internally, but considering that port 80 is taken (by pihole, outside of podman) I don't see a way to direct traffic from the pihole to Traefik.

      I'd really rather not reconfigure the whole setup to use containers.... I'm lazy, and also prefer my dns resolver to have the least amount of overhead possible. Is configuring the router an option here, or is the only way to achieve what I'm looking for an overhaul of the pi and containers?

      If I've missed any pertinent details, let me know and I'll update here.

    3. [Home networking] Setting my Ruckus APs to DFS channels manually, any chance of running afoul of the FCC?

      Hi everyone, I recently finally setup the Ruckus AP unleased system that came with my townhome. After spending a long night learning how to properly configure the system I finally set it up in a way that provided me the best speeds/range without interference.

      This was achieved by setting my Ruckus APs to manually sit on the DFS channels (60-140) via the Ruckus configuration app (shown here)

      This has been working great as I'm avoiding the 10~ other wifi networks in the area that are all set to the standard 36-48 and 149-160 channels (wifi analyzer screenshot here) but I'm concerned I may be inadvertently violating FCC guidelines. Note I do not live near any military installations, but I am about 13 miles away from a major airport. Will the Ruckus APs automatically change channels if they detect radar interference or am I causing trouble for someone?

    4. [SOLVED] Looking for help getting my VPN to work with Firefox privacy settings

      I recently moved to a new place with a new ISP, and my Mullvad VPN isn't playing nicely with Firefox like it used to. Can any of you networking gurus please help me troubleshoot?

      When the VPN is enabled, most requests from the browser fail immediately. If I pull up the dev tools Network tab, I can see that these requests fail with an NS_ERROR_FAILURE message before any data is transferred.

      I have Firefox configured to use "strict" Enhanced Tracking Protection. When I reduce it to "standard" my requests go through.

      I'm also trying to use DNS over HTTPS with a custom provider (Mullvad, via https://dns.mullvad.net/dns-query). I'm configuring this in Firefox, using the "Increased Protection" DoH setting. When I do that, Firefox reports the DoH status as "Status: Not active (NS_ERROR_FAILURE)". This happens even when Enhanced Tracking Protection is set to "standard" — in other words, that reduced setting fixed the NS_ERROR_FAILURE for HTTP requests, but not for DoH.

      So how do I fix this so Strict Enhanced Tracking Protection, DNS over HTTPS, and Mullvad all work together? I never had this problem with my old ISP, so I suspect something's being blocked at the WAN level that I need to circumvent.

      • OS: macOS Sonoma 14.5
      • VPN protocol: WireGuard
      • ISP: AT&T Fiber

      I'm just using the official Mullvad client app with mostly default settings. The fiber gateway modem/router came with some default packet filtering firewall rules but I disabled everything in the admin panel. Weirdly, rebooting my machine fixed this temporarily, but the next time I disconnected/reconnected the VPN it broke again. Other browsers (with default settings and no DoH) are working fine when the VPN is connected.

      Edit: Solved! Solution here.

      My apologies if this kind of content is not allowed here. Mod(s) please feel free to delete it if it is not without any butthurt on my part.

      I'm new to React Testing, so I am taking an Udemy course on it. The Udemy course uses yarn, so I would like to stick with that though I do know yarn isn't the top accepted tool in the React community.

      I've posted this question elsewhere, I haven't gotten any responses, so I am posting it here ( costs nothing ).

      I am getting this error when executing yarn build:

      $ yarn build
      yarn run v1.22.22
      $ react-scripts build
      Creating an optimized production build...
      Failed to compile.
      
      TS2305: Module '"web-vitals"' has no exported member 'ReportHandler'.

      error Command failed with exit code 1.
      

      I've tried installing web-vitals over what is already in the modules section, but that hasn't helped.

      Any clues appreciated!


      Update: the tip about ReportHandler being deprecated helped. I ran create react app in a new folder, did NOT run yarn update as the instructor called for,moved my work over, and now everything runs fine.

      trying to settle on a program where I can jot down stuff and have some degree of confidence that it will persist and I can't seem to find any actual documentation from vs code as to:

      1. How often unsaved files are saved so that they can be restored when a session is reopened
      2. if that frequency of how often they are saved can be configured?

      Sidenote: I was going to ask this question on SO but apparently I am at risk of a question ban for not asking "good quality questions". Half my questions on there are from when I was a fresh developer and didn't really know how to articulate my questions well. Really changes my opinion of the openness of SO......

      Today is my last day at work and my boss wants me to BCC anyone I have ever sent an email to announce my departure.

      I have tried exporting all my sent messages and trimming the list by advanced sorting out the duplicate email addresses in excel, but messages with multiple recipients are plentiful and need to have the emails separated into individual cells at the very least.

      I also tried the .NK2 file route. I downloaded the MFCMAPI program to find my hidden autofill contact file, but it can only be exported as an .xml or .msg file and I don't know how to handle those files properly to get the data I need.

      Does anyone here have a solution to automatically add every autofill contact on Outlook as BCC recipients for a final email?

      EDIT: I found a solution that worked for both of us. I emailed the clients I remember as the most important and set up an automated reply to handle those I forgot to message.

    8. A variety of beginner home server questions

      I will soon have a home and figured now's the time to do a proper home server, especially since it's going to come with cat 6 run from the main panel to just about every room. I code for a living, but at the same time network is a massive gap in my knowledge, as are servers, and I was hoping to use this as a learning moment as well as just a way to optimize things. I've been doing research for a few weeks now on and off and feel like I've got more questions than I started with, so I'll just vomit them out and if anyone has some guidance I'd really appreciate it.

      Some information:

      1. I'm willing/able to spend to get quality/simplicity. Time is the much bigger crunch for me right now, and I'd much rather buy something that works even if it costs more than cobbling together some deals.

      2. Related to 1, I'd like this to not become my fulltime second job/hobby. I will at some point try to expand to a full home lab, and do want to use this to learn about things I feel I should understand better for general knowledge and my career, but i'd love for core functionality to mostly "just work" after configuring so when I don't have time to do that I'm not stuck telling everyone "oh yeah it'll be broken until I find time to fix it".

      Things I know I want-

      1. Some sort of NAS. From my research Synology comes up a lot as the "it's expensive but it'll just work" option, and I probably want something like a 4 bay of NAS specific several TB HDD's in something like raid 5/6/10. Pricey as hell but I'm most willing to spend on this as the cost might very well be split by the family members who want me to guinea pig all this.

      2. I will have a camera system and would prefer to not have it sending data outside my network. This is the area i've looked at the least, as it's a little farther down the road, but I know others who have things like Arlo and lets just say i'm not super impressed. Obviously this brings up question like remote access to said camera's and where I'm storing the data (nas? Somewhere else?)

      3. I'd like to mess with a media server. Plex/Jellyfin constantly come up in my research, so I'll be looking into those, but I've also got a bunch of audiobooks that I'd love to be able to easily share, and I think there's software for that stuff as well.

      4. Pihole strikes me as the other "well if you're going to do this, you might as well" option that i'm aware of. Realllly need to better understand networking in general, but I hear these days it can kinda be installed and quickly configured and then left to do its job.

      5. Related to all of this, Casa OS keeps coming up as a very good tool for a beginner like me, since it streamlines the handling of docker containers and also file sharing. However it's not really an OS, since it must actually run on Debian (i think?) for now (zima OS still in testing?).

      Stuff I'd like to mess with but doesn't have to happen right away.

      1. Eventually the aforementioned NAS would be backed up offsite to another NAS at another family members house, once I know what the hell I'm doing.

      2. Proxmox constantly comes up as THE tool to use, but it leaves a lot of questions for me. Obviously if I start trying to do lab environments and screw with VM's it's going to be great, but my understanding is that I probably don't, as a beginner, want to say load up a device with proxmox and then have it host debian which installs CasaOS as it'll get a little more tricky to have everything talk right? Unsure on this part.

      3. Anything else I'm forgetting. One issue I keep having with this is a LOT of the information out there is either too complex for me to really grok or just says "well yeah you could do ANYTHING with this" and it just sorta assumes I know what the options are. If there's anything else worth checking out I'd love to know.

      Hardware I've come across-

      1. Synology - Already mentioned but seems like they're a common go to for a "more money than skill/time" situation like mine.

      2. Zimaboard - My understanding is it's underpowered for its price, but the main draws are that it's VERY low power, small, and quiet. What it could actually do from my list above is where i'm unsure. I see people are supposedly using it for Plex servers and what not, and I'm pretty sure it's not going to make any kick ass lab environments, but being quiet, small, and maybe a bit closer to plug and play seems tempting (I know they make the blade and a few other products but it all seems greek to me).

      3. Various mini computers - I've got a minisforum machine from several years ago that I currently use as a living room computer for light gaming and mostly playing movies and the like. Not sure if i could just wipe it and convert it to be the starting point (more on that later). I know used 1 liter mini pc's from companies like HP are also popular.

      4. The MS-01 - Similar pile as the last one but my understanding is this is the kind of thing that's probably really cool if you actually know what the hell you're doing. I'm 99% positive it is vast overkill for my purposes, but I'd like to eventually get to the point where I could understand why I might want something like this. My understanding is if I knew what I was doing I could probably drop proxmox on this and do everything I could ever want and more, but I feel quite far from that.

      Some general questions I have -

      1. The thing that kicked this all off is my new place likely having fiber, and cat 6 drops throughout the building. Architecture is something I'm still a little shaky on. I assume i'm going to need my own modem/router (just because the cox routers are meh and not really configurable from last I checked), and then that routes to the server first???...or something(seems like a must if you want the pihole to do anything)? I've seen lots of niffty network diagrams at this point but they're all from people WAAAAAAAAY beyond my skill level doing much more ambitious stuff, so it gets hard to understand. If anyone has a simple home network diagram/guide to look at I'd really appreciate it.

      2. I'm just in general going to need to learn more about networking, especially in a home environment. Should I eventually get those camera's set up, I want to understand how to let them talk to internal storage and what not ,but not get out to the web...or..something (again remote access seems nice, but also like a massive security concern). I know speed is also a big factor i'm going to need to better understand. Having a fiber connection in only to be bottle necked by a crappy router or a 1gigabit port is just a waste of money, so that's something else I'd like to better understand.

      3. I'm a little unclear on how to deliver the media in a media server to the various screens throughout the building. I've got cat 6 to all of them, but I suspect i'm still going to need, at the very least, a cheap computer to hook up to it and then display the image to the monitor/TV? This is why I assume I can't just wipe my current mini PC and reuse it as a server, because I still need it to receive the data from the home server (or at least a web browser?). A part of me feels like if I got a powerful enough server it should be able to server the media direction to the screen, but then you'd need some sort of HDMI/DP drops as well from the server to all your screens?...or something?

      Sorry for all the rambling but I've got an odd mix of knowledge and ignorance so it's been a little difficult to research when half the video is stuff I already get, and the other half blows past me or just assumes I know about the parts i'm trying desperately to learn about.

      Pseudo because upgrading some of the parts might have a knock-on effect for other parts. Might end up leading to an upgrade of the whole system, idk. So here's a list of parts that I've already acquired. I was originally going to use some of them to fill out the Framework laptop that I pre-ordered... but I had an expensive couple of months earlier this year and figured I could wait on it. :(

      Part
      AMD Ryzen 7 7700x
      Crucial P5 Plus 2TB PCIe NVMe M.2 SSD
      (2) 16GB GSkill Flare X5 DDR5 6000 RAM
      $50 Microcenter gift card

      Now here's what I have in my tower currently.

      Part
      Rosewill Thor V2 ATX Full tower case
      Intel(R) Core(TM) i5-4670K CPU
      (2) 8GB GSkill DDR3 RAM
      Rosewill 650W 80 Plus Gold PSU
      MSI Z97-GD65 MOBO
      Gigabyte Nvidia 970x Windforce GPU
      1 SanDisk Ultra Plus SSD 250GB
      1 Seagate HDD 1TB

      I'm looking to keep the tower at the very least and reuse it for new components. Right now, I know that the mobo will absolutely need to be replaced IF I'm throwing the ryzen chip in. And with knock-on effect, probably the psu as well since these components are drawing more power. The goal is to get a solid 60 fps on Helldivers (which I can't do at the moment, even on the lowest graphical settings) since it's the most intensive game that I play. With this goal in mind, does it make sense to start using the components I have from the first list, or might it be cheaper to keep them for the framework and get older (still compatible) parts that would fit right in to the system as it stands?

In addition to working every day I would like to: legally stream movies in the evening, work on writing, email friends etc. At home of course I use a separate laptop for this but in this case I won't have that option. Any thoughts on how best to achieve a separation of concerns while travelling? How do people on Tildes manage this case?

      I recently started having an issue on my windows machine with folder permissions. The start menu folder suddenly became inaccessible to any program that tried to create a shortcut there. I worked around it by just taking ownership.

      Now I'm facing a much worse problem where many operations that require admin elevation suddenly doesn't work even after a UAC prompt. This has really become a problem now that I want to install wsl on this machine. Running wsl --install just returns the wsl usage info and wsl --update throws a UAC prompt, but fails saying "The requested operation requires elevation" even while logged into the built in Administrator windows account.

      Normal programs can still use admin elevation (mostly), but everything that windows prompts for behaves as if I'm a regular user despite still giving and accepting a UAC prompt. The Microsoft Store has also seemingly lost the ability to update or repair itself also so that's probably related.

      I've tried all the usual stuff with /DISM, /sfc, every Microsoft troubleshooter. They found no issues. Creating a new admin account lets me create the account but then it inherits the same issues. I can't even gain admin elevation in safe mode. I'm really at a loss. I don't want to have to do a system refresh because it takes so much time to get set back up, but at this point I don't know what else to do.

      Has anyone else ever encountered an issue like this? I've tried searching for this and just end up on a bunch of identical 'help' pages telling me to right click -> run as admin or the generic Microsoft employee pointing me to reinstall again.

      Windows version 10.0.19045 Build 19045 in case that matters

      Edit: I never did find a solid reason why this was happening. It wasn't my university Maya account. While reinstalling windows on a freshly formatted drive I kept getting errors that eventually led me to discoving my ram was going bad. Got it replaced and installed windows just fine. I have to assume the problem started because of memory errors. Thanks for the suggestions everyone.

      I have been running a DAKBoard on a Raspberry Pi 4 for almost 4 years now without any problems until recently following this guide IIRC.

      About 2 weeks ago, DAKBoard started logging itself out and only shows a black screen with the time on it and the DAK logo in the lower right corner. If I go into the settings it will bring up the DAK page that shows I am not logged in. When I log in again it seems to work randomly for about 24-36 hours.

      I'm running it in a kiosk mode browser on Raspberry Pi OS. I am using the free tier of DAKBoard.

      Before I wipe the SD card and start over from scratch I was wondering if there were any suggestions? To be completely honest, it has been "set and forget" for the past number of years so I would like to make sure I'm not overlooking something pretty basic/easy.

      On a side note: Has anyone had any experiense using the DAKBoard OS on a Pi? I don't remember it being an option when I set it up originally.

      Thank you for any assistance and if you have any spare hardware laying around I'd highly recommend setting one up, my family finds it incredibly useful for the calendar function and a conversation piece when they notice different photos rotating in and out.

      There isn't the Dark Theme that's available for original duckduckgo site.

      I found a "My filters" rule on the web.

      Add these two lines to My filters

      lite.duckduckgo.com##a:style(color: rgb(201, 201, 201) !important;)

      When the rule is used the search homepage looks reasonable.
      And the search results...
      The black background is not very black, not as black as Tildes black theme.
      I can live with that.

      But the red text under each result is very muddy.
      Can that be improved?
      Make it brighter Crimson or even Orange would look better.

      So... a friend did this for me a long time ago, but I've replaced my computer since then, and I don't know how to do it for myself.

      I know how to find the MAME executable. I don't know whether I need to download the .exe file or the .zip file, but I assume the .exe file is the better option.

      I know how to run an executable file, and I'm assuming it installs itself.

      I know how to find a copy of the antique video game I want.

      However...

      The .zip file I download for the game contains a lot of files with names like "a26-13.109" - and I don't know what I'm supposed to do with those, to get them inside the MAME and make the game playable.

      I'm running Windows 10 on a 64-bit operating system, if that's relevant.

      Is anyone feeling charitable and willing to help someone who's not computer literate to do this?

      I tried to use Gnus to set up some rss feeds about a year ago, and I became more than frustrated: I was actually confused.

      So here are a couple questions I don't even understand where to ask or whether they're relevant or being asked in the right way:

      Are most newsgroups mirrored? And along those lines, is there one particular newsgroup server that would be sufficient for most users?

      Can I post to a newsgroup in the same way I would post to a mailing list: send an email somewhere? Where do I send that?

      What even is NNTP? Someone literally sent me the spec for the protocol, but I don't think they actually wanted to be helpful: I felt like they were putting me down and intentionally not answering while giving the appearance of being helpful. Is it actually something I need to understand to use Gnus effectively?

      If you're familiar with newsgroups, I would surely appreciate your knowledge.

      Howdy Tildes wizards.

      I decided to have a looksy at Stable Diffusion on my local computer (Manjaro, AMD 7500x CPU, 32GB) using Easy Diffusion. I've gotten my head around the basics and grabbed MidJourney V4 LLM, and now I'm learning how to prompt.

      So far I've generated some cool cyberpunk cyborg things, landscapes, etc. One of the things I wanted to use Stable Diffusion for is generating silhouettes. Sounds weird, I know, but they're great to use with decal and vinyl printing for my wife's business.

      Any ideas on ways to do silhouette generation?

      Next is, what's good to read to learn about model types and what all of the settings really do?

      I'm ordering a GPU (3060) to improve the horrendous render times, so don't worry about the under powered rig, I'm still in toy mode.

      I cannot push nor pull to/from my local repo to/from my remote. I get the message "Your branch and 'origin/main' have diverged", etc.

      I will be able to fix it, I'm already in the process of refreshing my memory on how to rebase this cleanly.

      But ... I am the only person working on this. I have only one local and one central/remote repository. And I never made a branch.

      It's just me, working on one computer, right here ... make a few commits locally, then push 'em ... make a few commits locally, then push 'em. That is my entire workflow.

      How in the hell did I end up with "my branch" (???) and the origin/main branch being in conflict with each other?

      Any Git gurus care to take a stab at this?

      Thanks in advance.


      Edit, more info:

      I am guessing here, but for awhile I was working in a VM on my local machine ... but Android SDK is too much of a resource hog, so I committed and pushed everything on the VM, shut it down, and then pulled latest down to my actual machine ... or at least, that's how I remember it.

      My working theory is that, somehow, I screwed up that "switching between machines" process, although, so far, no clue as to how/why I did.

      Theory #2 is that Android SDK did something sneaky/stupid behind the scenes -- my last several commits have been done through the Android Studio IDE, not directly in the terminal.


      Last Edit:

      D'oh!

      Found it. I made a couple of "quick changes" to the project's README.md file directly in the remote forge, and that's what screwed me up.

    18. Linux Question: I think my sys m.2 is failing and want to copy my / data for backup via cli

      So, I'm using Arch i3wm. I have multiple copies of my /home/username (I am the sole user), and I have a "Spare" drive with media, games, and other goodies, some of which are also stored on partitions on the m.2 in question, but they have backups.

      And the reason I ask this question is because while I've had my m.2 fail at the end of '21 (I didn't even know that was a thing, but it barely lasted a year, and things are acting shoddy now... though the original failed without a warning), I just bought a second m.2 for my games. I guess I could swap most of the whole thing over, but I know the boot partition is easier just rebuilt from scratch... which I had to do last week.

      Ultimately, what's making me suspicious is when I upgraded to the new drive and unplugged all my non-m.2 satas, I also added some memory and a new power supply. But then after the upgrade (Monday of last week, so the 5th), the system wouldn't boot up. I used a usb to troubleshoot and my /boot partition was apparently no gouda. I redid that, and everything was fine... until this week. Then my new Games partition (basically the new drive) failed fsck and it got stuck in a boot loop on Tuesday. I could boot emergency to root, but not skip the fsck and keep the Games disk auto mounted (I know I changed something to randomize fsck on bootup, but that's something I'm still kinda looking into how I managed...), so I just removed it from my fstab and it booted fine. For two times. I just manually mounted the drive, all was great, then my SO sent me a screenshot today while I was at work stating that my / partition (on the older m.2) apparently rebooted because it bypassed my screen lock, and was stating EXT4-fs error, reading directory lblock:0 and whatnot.

      So, that's my history on what's going on, and if anyone can offer any advice [mostly] on the backup stuff, though as I said, /home and the important tangible stuff is saved, but if you also have any input on something more than I suspect the drive is failing (since the /boot partition and now the / partition are crapping out), please feel free to share.

      (Also, thanks for letting me in. This is what I'd typically post on reddit and probably have to repost 10 times depending on the sub to get the right keywords and tags and yes, I already searched the internet but my search will not match yours... sigh)

      I have to preface this question with a disclaimer that I am an eager learner of Linux and servers in general, but I'm still a beginner and often run into roadblocks.

      Current setup:


      • Raspberry Pi 3 with Adguard Home acting as primary DNS
      • unRAID server with Adguard Home acting as secondary DNS
      • About a dozen other containers running on same server
      • DHCP is handled by my router

      Goal:


      • provide local DNS names for the containers running in unRAID so I don't have to enter IP:Port (e.g, calibre.local) which also has the side benefit saving the various username/password combos into Bitwarden with an actual domain attached to it instead of 14 occurrences of 192.168.x.x

      Additional info:


      I had PiHole running on the Pi before as the primary and only DNS previously. And I seem to recall you could put IP:Port as a custom DNS and have it resolve. AGH does have a feature for DNS Rewrites but it does not allow for port numbers, IPs only. I switched to AGH because it seems to be more effective at blocking ads, which is likely more a function of the provided DNS blocklists out of the box as opposed to what I was doing in Pihole. I would prefer to stick with AGH for adblocking/DNS if possible.

      I looked into just modifying host files on the main computers I touch these apps from, but again, can't include port. What is a good solution for this? Preferably something approachable for a newb like me.

      I've got a problem with my nextcloud and as tildes is my favourite nice place to ask for tech-support, maybe somebody here can help me with that.

      I can start and run Nextcloud AIO without any problems. I can update the subcontainers without any problems.

      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.

    25. Docker rootless and Watchtower and some general questions about Docker

      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 :-)

      This is a total longshot. I moved away from a WD My Cloud EX4100 w/ 3x WD Reds to a new box. I bought two more drives for the new one to make the move easier.

      After the move I took the drives out to format them only to find that each 4TB drive shows a partition of 1.8TB on any other system (diskpart with W10 LTSC, Disk Utility MacOS, and GParted with Ubuntu.) Inside the EX4100 the drives show their full capacity.. and I just don't get it.

      I reached out to their support, but I don't expect much of a response.

      Anybody have any idea why the heck this could be happening? This seems crazy. I don't mind buying more drives, but it seems like a waste when I've got 12TB just sitting there.

    27. Continuing My Education with a CS Degree in Canada [A Help Thread]

      My Goal I am applying to Canadian universities for fall admission as a CS major. This will be my second degree, and one of the requirements of getting admitted for a second degree is to show that...

      My Goal

      I am applying to Canadian universities for fall admission as a CS major. This will be my second degree, and one of the requirements of getting admitted for a second degree is to show that you have a significant interest in the subject. My plan is to get online certificates to show that I am actually dedicated to learning CS and getting a job in the field. I am actually dedicated, I just need a way to show it on paper. I have some experience with software development (only the basics), but there aren't any records of it since it was just informal study.

      My Problem

      I can't decide which certificates I should pursue. I am torn between EdX and Udemy. I would Tilderinos' help in choosing between the two. I would also appreciate any general advice you may have.

      Here are the courses I plan to take on EdX (prices in USD):

      UBC's MicroMasters Program in
      Software Development
      - $832

      Harvard CS50's Web Programming with Python and JavaScript - $199

      IBM's Professional Certificate in
      Cloud Application Development Foundations
      - $169

      Here are the courses I plan to take on Udemy:

      The Ultimate 2021 Fullstack Web Development Bootcamp - $15

      The Complete 2021 Web Development Bootcamp - $15

      The Ultimate MySQL Bootcamp: Go from SQL Beginner to Expert - $30

      Angular - The Complete Guide (2021 Edition) - $15

      Comparisons

      To reiterate, I have two goals going into this. One is to actually learn web development, since I would like to become a fullstack developer (but my options are semi-open). The other is to prove to the Canadian universities that I am dedicated to learning and to give myself an edge over applicants.

      If I go with EdX, then I have to pay a much steeper price for the certificates. These courses also take a long time to get through and the projects don't seem as relevant to real word applications. But I will also be learning from established institutions like Harvard and UBC. EdX certificates also come with the distinct advantage that a human is checking the problem sets you submit. This will show the Canadian universities that I have actually spent the time and effort to go through the courses and pass them.

      If I go with Udemy, I will get through the courses in less time and their projects seem more related to real world projects. If I go through the courses faster, I will also have more time to start on some personal projects, and I can show my dedication to learning through those projects. Personal projects and also volunteer work will also help establish a resumé for future work. The courses on Udemy are a lot cheaper too. But they don't have the same level of verification or prestige that EdX does.

      So in summary, EdX has prestige and quality courses, but a steep prices and a huge time commitment. Udemy is cheaper and gives me more opportunities to do personal projects and volunteer work, but it's certificates aren't fully trustworthy from the Canadian universities' perspective.

      Final Words

      What do you think? Which path should I take?

      For those of you wondering, why I am going to university instead of a bootcamp, it's because I plan to immigrate to Canada and becoming a student seems the straightest way of getting PR. I need to leave my third world country as soon as I can, for mental health and economic reasons. I have been mostly unemployed ever since the pandemic started so I can't get work in Canada (or the U.S.) on my first degree (a management degree). I already tried that route. I can't find proper work here either.

      Also, I am sorry if I posted in the wrong group, or if I shouldn't have posted it anywhere at all. I desperately need advice on what to do and I don't have a trustworthy network here that can help me through this. I'm sorry and thank you for your help.

I run both uMatrix and NoScript plug-ins (among others) in my Firefox browser, so I can see when and where websites send calls out to other locations, and block the ones I want ... google analytics, google fonts, google-apis, google tag manager, and gstatic are all ubiquitous out there, probably 99% of websites use at least one of them (PS: Tildes is in the 1%; yeay, Deimos).

      And note ... there may well be nothing at all wrong with any of those sites/services ... but Google has a global all-encompassing Terms and Conditions policy that says, you use anything of Theirs, and They are allowed to harvest your personal data and make money off of it.

      And I do not accept those terms.

      Okay, that's the prologue. The deal is, I have a small piece of documentation, just basic "how to use this" info, for a WordPress plug-in. It is in .html format, with bundled bootstrap and jquery and a few other assets.

      Nothing, anywhere in the entire folder, references gstatic. And yet when I open this local, on-my-computer-only html file ... my browser tells me that it is trying to connect to gstatic.com.

      Anyone happen to know why/how that is happening?

      I have a CalDigit TS3+ dock that I switch between my M1 Macbook Pro and a System76 Galago Pro that's currently running Windows 10 (I'm sorry, FOSS gods). The M1 has no problem using the TS3+ when it's connected or disconnected and reconnected. But the Galago Pro will only connect to the dock if it was connected while booting up. Disconnecting and reconnecting leaves the dock in a state where only the pass-through thunderbolt port works. So my monitor that uses the pass-through for DisplayPort can operate after reconnecting the dock, but no other devices plugged into the dock will. My mouse/keyboard for example don't even receive power in this state.

      Oddly when setting up the drivers for thunderbolt I found that the only drivers available are for Intel's NUCs. IIRC someone on reddit said that this is actually the software I need to install, so that's what I did.

      Any help getting the dock to work better is appreciated! Currently I need to reboot the laptop every time I switch back from the M1 to the Galago Pro.

      In the DC canon, The Mobius Chair is a time-space/dimensional vehicle operated by the New God Metron. It allows him to travel and observe the universe, but the one I'm making is nowhere near as functional.

      I've come into a recliner chair with a cupholder on each armrest, and I already had a split keyboard. My plan is to use the cupholders as a mount for both ends of the split keyboard, so that I could use the entire run of armrest and have my hands lay naturally on the keys. Goals are to minimize weird stretching and be able to comfortably type for long stretches of time, to put off stuff building this that I planned to work on this weekend, and to look super boss, though not necessarily in that order.

      If I want ultimate angulation and the best range of motion, I was thinking about something like a cupholder with a phone or a tablet mount, like this one, but if anyone has recommendations for what would be best to work with, or have done something like this before, I'm all ears.

      Hello everyone. I consider myself fairly competent when it comes to my work with LaTeX, but as everyone who uses it knows, it is definetely strange sometimes. And right now I have a problem which just irks me in the wrong ways:

      I use XeTeX and a number of custom fonts for my documents, but when writing mathematical formulas I found out that the font I set for Greek letters (Gentium Plus) is used for letter commands like \alpha, \Alpha, ... but not for commands like \sum, \prod. As you can see in this example here. You can see XeTeX defaults to Computer Modern.

      I've looked all over the net for solutions but I can't find one. I'm using mathspec, amsmath, amsfonts, amssymb as my font related packages and I set my fonts like this:

      \setmainfont{Charis SIL}
      \setsansfont{Helvetica Now Display}
      \setmonofont[Scale=MatchLowercase]{Fira Code Retina}
      \setmathfont(Digits,Latin){Charis SIL}
      \setmathfont(Greek){Gentium Plus}
      

      I feel like I'm going insane not solving this problem. Should you require it, my entire LaTeX template is here on Github. Please help, thank you.

      I want to adopt these technologies b/c I'm moving to a home w/o WiFi: I'll only use mobile networks in order to save some money. But the general pipeline and setup are hard to digest, and I'm not sure if I really understand what are the implications for my privacy, except for the fact that DNS queries are encrypted so I don't leak domain names. This is especially important to me because Turkish internet law and the censorship mechanism is really intrusive, with DPI & DNS blocking. My current ISP does not fiddle with my HTTPS traffic, but I won't have that with my mobile network.

      I'm also considering a VPN, but major VPNs are blocked here. To what extent do the purposes of VPNs and these DNS solutions overlap? Assuming most of my important traffic is over HTTPS+DoH/T, how safe am I, and most importantly how much can I penetrate the censorship mechanisms?

      Hey Tildes!

      I've got a static, basic website, HTML and CSS. It's one page only. But I'd like to create a second page with some more private content that is password protected.

      I know that I can accomplish this via .htaccess but what I don't like about this method is that when the user navigates to the page, they get a pop up asking for a username and password. What I would like is having the user navigate to the page, and then they are met with a simple form asking for just a password (no username). After they enter the password, the "veil" lifts or the page forwards and they get the private content.

      Here's the thing... the content really only needs to seem private. It's not super secret, personal information. I don't want it indexed by search engines (nofollow), and I want it basically hidden, but the password is only there to make the user feel exclusive. If some tech-minded person encountered this page and jumped through a bunch of hoops to get in without the password, it's not a big deal to me. In reality, 99.9% of people accessing this page will not be able to bypass the password.

      I'm guessing this can be accomplished easily in Javascript, but I don't really know much Javascript apart from finding code snippets and plunking them in. I also want to be able to fully design the password entry page so that it looks branded, so a code snippet plunked down into my HTML doc would be great for this.

      If there is an easy way to actually protect the content behind the password, that would be excellent. In this case, I imagine it would be much like a news site with an ad-blocker-blocker. Just some kind of pop-up that blocks all the content. Enter the password, and you're in.

      Anyhow, I hope I've described what I'm looking for accurately enough. Anybody have any easy and quick ways to accomplish this?

      I'll be writing a relatively large piece of scientific code for the first time, and before I begin I would at least like to outline how the project will be structured so that I don't run into headaches later on. The problem is, I don't have much experience structuring large projects. Up until now most of the code I have written as been in the form of python scripts that I string together to form an ad-hoc pipeline for analysis, or else C++ programs that are relatively self contained. My current project is much larger in scope. It will consist of four main 'modules' (I'm not sure if this is the correct term, apologies if not) each of which consist of a handful of .cpp and .h files. The schematic I have in mind for how it should look is something like:

      src
       ├──Module1 (Initializer)
       │         ├ file1.cpp
       │         ├ file1.h
       │         │...
       │         └ Makefile
       ├───Module2 (solver)
       │          ├ file1.cpp
       │          ├ file1.h
       │          │...
       │          └ Makefile
       ├───Module3 (Distribute)
       │          ├ file1.cpp
       │          └Makefile 
       └ Makefile
      

      Basically, I build each self-contained 'module', and use the object files produced there to build my main program. Is there anything I should keep in mind here, or is this basically how such a project should be structured?

      I imagine the particularly structure will be dependent on my project, but I am more interested in general principles to keep in mind.

      I've been trying to set up a reliable lightweight solution for high quality, low-latency webcam (v4l2) streaming from Linux server to browsers, allowing for small (1-5) number of concurrent viewers.

      The obvious choice here is WebRTC, which when used through browser APIs, works wonderfully. It has low latency and automatic quality adjustment depending on network performance.
      I also checked out RTSP and RTMP, which are not supported without browser plugins. Next candidates were DASH and HLS, but while they provide high quality, they also have high latency.
      For a while I used MPEG1 streaming through Websockets (using jsmpeg library), which worked and had low latency, but the video quality was bad.

      Back to WebRTC - It seems like reliable, lightweight and maintained projects are really hard to find. So far I've found a few WebRTC media servers, but they're overkill for my use case:

      • Janus
      • MediaSoup
      • Kurento (unmaintained)

      I also tried implementing this functionality using low level Gstreamer elements in Python using PyGObject, but that's proving to be rather complicated with a ton of extremely low level implementation details.

      If anyone has tried doing something similar, I'd really like to hear what (if any) problems you had and if you found any sane solutions. Next thing on my list is using headless Chromium in combination with Puppeteer, but I'd really prefer more lightweight solutions.

      I just received a mail from my own e-mail address, hosted on Gandi on my own domain name. It said that the sender has hacked me, used malware, keyloggers and RDP to get my passwords and copy all my files to his own computer, and took videos of me while watching adult content using my webcam (I never noticed the light turning on for it). Claims they've been doing this for a few months. Gives a bitcoin address and wants $1000 (a sum I can't and won't give, don't even have a fraction of it) in 48 hrs, or else will share the videos with my contacts. It said something about a pixel the message included.

      I viewed the message from K-9 mail on android (which didn't tell anything about pixels or whatnot), and when I went back on my computer to check the headers and stuff, the message was deleted.

      Now, is this some sort of phishing or or have I really been pwned? I feel like it's just phishing, but the message deleting itself kinda gave me shills of fear. I promptly changed my password for the mail account.

      I have just graduated from uni, and am preparing for masters next fall. I'm a humanities student, but have some programming knowledge. Currently I'm looking for literary translation jobs, but should I fail that, I want to find some light freelance work (so that I can spare more time to my studies), and looking at e.g. freelancer.com, Wordpress is still quite popular.

      What are some good introductory material for Wordpress and PHP, that preferably does not assume total beginner to programming? How much can I expect to make, for how much effort? I'd be content if I could make $200-250 w/ 3-5hr work per day, or a couple full days a week, that's all I really need and such hours would mean that I could keep on doing such work even when I'm writing my thesis. I'm in Turkey, FWIW.

      Hello everyone!

      I've recently got an idea for a Database as a Service I'd like to create. The only issue is - I don't know how to create or host a database!

      I've only ever used Mongoose/mLab with Javascript, and a minimal amount of Postgres with Python.

      If I'm looking to create a database that will, eventually, be able to store images, songs, and videos, where should I start my homework?

      I can create the backend and the frontend with no issue - just stuck on this part here. If it's of any relevance, I most frequently use the MERN stack.

      I'm currently looking for a new monitor and I have the ASUS MG279Q, the ASUS PG248Q and the ASUS MG278Q. Now, my setup is not the highest end, but decent with an i7 and a 1060 3GB, and there are three concerns I have currently not found an answer for:

      1. The (potential) difference in quality between the MG279Q's IPS panel and the MG278's TN panel
      2. And the delay difference, the TN panel having a 1ms response time and the IPS' 4ms
      3. If my setup can even handle 1440p/144Hz (I don't need to play on the highest settings, nor do I need to reach those 144 FPS), in which case I would tend more towards the PG248Q

      I'd love to upgrade towards 1440p as the screen real estate would be good for working (which I do a lot on the PC) and I would, I could later upgrade my GPU if the performance in games isn't satisfactory. I think my setup wouldn't have any issue handling day to day tasks and if need be I can play on lower resolutions or lower graphic settings. Also I wonder how large the difference between the IPS and TN panel is and if it's noticeable, particularly with colours.

      Does anyone of you have experience with the subject or with the monitors named in particular?

      I have been interested in making the gradual career change to software development from my current humanities field. This stems from a handful of different places. Of course the pay and flexibility are strong drivers but I like the idea of a field that is somewhat of a creative expression; one where you can manifest your knowledge and experience into something tangible.

      I have no experience with programming other than SQL use in ArcGIS and am hoping to gain some knowledge about the field; so anything would be helpful. Whether what to expect from this line of work, where someone with no experience should look to get started and what to expect, personal journeys, etc.

      Okay, I know the obvious answer is the history of the files. But how can I, from the command line, really understand what is hiding inside that .git directory?

      Today I was doing one of my periodic disk space audits, trying to figure out where my usage goes. This comes from having a 64GB drive mounted as /home on my Linux laptop. I found some 15G of old video files to delete today, so I'm no longer as pressed for space. But my interest was piqued by one thing I have downloaded from Github that is ~120 megs for a very simple program. Poking around further I find that most of that usage is a single file:

      $ ls -lh withExEditorHost/.git/objects/pack/pack-df07816cd15fb091439112029c28ebc366501652.pack

      Is there a unzip or tar xzf equivalent for Git pack files? Naive usage of git unpack-file is only generating errors for me.
