I mean, my SUV is a 2004 and seems to be holding up pretty well. I give it full synthetic oil and take it off-road occasionally, so it gets a wide range of treatment. Maybe I'm just not as bothered as other people are by the occasional bit of maintenance. I just replaced the thermostat this Fall, which was certainly a lot harder than on the old car because this one is buried down along the side of the engine, but it was still a pretty simple job.

It was a '74 Pontiac LeMansthat I bought in 1987. And sorry, I did forget about one thing... I had to replace the transmission a couple times, but back then you could get them from a junkyard for cheap, and it only took a couple hours to replace. Probably would have lasted a lot longer if I'd taken the time to rebuild the clutches though. Of course it's not like you can drive any vehicle forever, there was the maintenance as things like bushings and alternators wore out. For this discussion though I don't count things that you have to do on any vehicle with 300k miles on it. Everything wears out eventually, and yeah even the motor was starting to smoke by that time.

That's what rich people are for -- to suffer for the benefit of the working class.

Never buy new. Let someone else deal with the frequent hassle of getting all the problems fixed "under warranty" while the lemons get sent to salvage. Give me the vehicles that survive. Case in point, I bought my first car for $500, drove it for 24 years, and the biggest age-related expense was rebuilding the front end for $600. I sold the car in 2011 for $1000. I bought my current SUV in 2009 and the biggest mechanical failures have been replacing the power steering pump and the 4WD short axles.

I had a friend who insisted he needed to spend all his money buying new cars. He tried to tell me how much money he was saving because the dealership was fixing all the problems for free. I pointed out that he had barely even driven his new car because it was spending more time at the dealership every week or two and he was constantly wasting his own time taking it back for yet another problem.

If they weren't on X and were reading reality-based information, they would already know the entire world hates Trump's politics, and I certainly don't blame anyone for hating the entire US in general. Too many people here will gladly hate an entire country even when they had no say in choosing their leaders, so it's only fitting to see that attitude thrown back at us.

On the other hand, the exposure that all these Trump-supporting "influencers" are foreign bot accounts is hilarious, and I love that MAGA is finally being shown exactly who they've been listening to.

Your server needs to have a static IP address. Once you have that, and have your DNS service set up, then you should be able to update your domain(s) to point to the new DNS. This new server doesn't have to be your primary DNS entry for the domain(s), but it should be one of the first two entries. And that's pretty much all you need to get started.

One other consideration is setting up the master/slave status of your DNS servers so you only have to make updates in one spot (helpful to ensure everything stays in sync). This isn't a requirement, it just makes your life easier.

Oh damn, I've seen short bits of this comic on reddit, I didn't know they had a web site!

Got a few minutes of ~~503~~504 gateway timeout errors here, but the pages just loaded back up again.

Nope, programming is like a black hole -- once you've entered the event horizon it's too late and you'll never escape.

What do you mean by "traditional cad designers" and why is that important? I'm not really sure why that is something that should matter to me?

Another consideration... If you are a programmer type then OpenSCAD is a language-based program. I've been using it heavily for the past week designing a dual-filament extruder for my Ender 3, and last year I designed and built a utility trailer. As with anything it has its quirks, but I'm much more comfortable writing code and I always found the other GUI-oriented programs to be unintuitive.

We should start posting that 3.2% of children watching Trump on TV have developed autism, therefor Trump is using subliminal messaging and is dangerous to their kids. They may not care that a pedophile is in office, but mention subliminal messaging and they'll go crazy.

 

I'm wondering if anyone has found (free) sources of data to use for live elections results, specifically the Presidential race? I've been building a map of poll results but would also like to put something together to watch the race tomorrow night.

 

A 1930s-era breakthrough is helping physicists understand how quantum threads could weave together into a holographic space-time fabric.

 

I would love to have them light up like a scoreboard as each representative takes the floor, showing all of the commandments they have broken. If people want so badly to bring religion into politics then lets just show them exactly who they've been voting for. Maybe we can get the news networks in on this too, displaying it on the side of the screen similar to a sporting event.

 

Marjorie Taylor Greene, the bastion of factual information, has once again shown the nature of her character by claiming that peaceful protestors at the Capitol are in fact an "insurrection of terrorists". Don't you see all the violence and mayhem being caused in this video clip? No, me either...

If you want to make such bold comparisons, lets start out by checking how many people are running for their lives or the number of deaths involved between these two events. Or maybe we should be asking why MTG thought it was an "honor" to meet with the people responsible for murder and the attempt to destroy our democracy?

 

I've seen the occasional blip here, but this is the first time I've seen a complete outage of this instance. Hoping @Salamander wanders through and gives us the scoop?

 

I have an annoying problem on my server and google has been of no help. I have two drives mirrored for the OS through mdadm, and I recently replaced them with larger versions through the normal process of replacing one at a time and letting the new drive re-sync, then growing the raids in place. Everything is working as expected, with the exception of systemd... It is filling my logs with messages of timing out while trying to locate both of the old drives that no longer exist. Mdadm itself is perfectly happy with the new storage space and has reported no issues, and since this is a server I can't just blindly reboot it to get systemd to shut the hell up.

So what's the solution here? What can I do to make this error message go away? Thanks.

[Update] Thanks to everyone who made suggestions below, it looks like I finally found the solution in systemctl daemon-reload however there is a lot of other great info provided to help with troubleshooting. I'm still trying to learn the systemd stuff so this has all been greatly appreciated!

 

Just in case there are others like myself who rarely check reddit any more, I thought it would be helpful to cross-post this. It won't look like much unless you have the solar eclipse glasses, but I plan to break out my tracker and camera (with solar filters!) to try and get some pics.

 

I've spent the past day working on my newest Poweredge R620 acquisition, and trying to nail down what things I can do without checking. Google has shown me that everyone seems to be having similar issues regardless of brand or model. Gone are the days when a rack server could be fully booted in 90 seconds. A big part of my frustration has been when the USB memory sticks are inserted to get firmware updated before I put this machine in production, easily driving times up to 15-20 minutes just to get to the point where I find out if I have the right combination of BIOS/EUFI boot parameters for each individual drive image.

I currently have this machine down to 6:15 before it starts booting the OS, and a good deal of that time is spent sitting here watching it at the beginning, where it says it's testing memory but in fact hasn't actually started that process yet. It's a mystery what exactly it's even doing.

At this point I've turned off the lifecycle controller scanning for new hardware, no boot processes on the internal SATA or PCI ports, or from the NICs, memory testing disabled... and I've run out of leads. I don't really see anything else available to turn off sensors and such. I mean it's going to be a fixed server running a bunch of VMs so there's no need for additional cards although some day I may increase the RAM, so I don't really need it to scan for future changes at every boot.

Anyway, this all got me thinking... it might be fun to compare notes and see what others have done to improve their boot times, especially if you're also balancing your power usage (since I've read that allowing full CPU power during POST can have a small effect on the time). I'm sure different brands will have different specific techniques, but maybe there's some common areas we can all take advantage of? And sure, ideally our machines would never need to reboot, but many people run machines at home only while being used and deal with this issue daily, or want to get back online as quickly as possible after a power outage, so anything helps...

 

I have been struggling with this for over a month and still keep running into a brick wall. I am building a new firewall which has six network interfaces, and want to rename them to a known order (wan[0-1], and eth[0-3]). Since Bullseye has stopped honoring udev rules, I have created link files under /etc/systemd/network/ for each interface based on their MAC address. The two WAN interfaces seem to be working reliably but they're not actually plugged into anything yet (this may be an important but untested distinction).

What I've found is that I might get the interfaces renamed correctly when logging in from the keyboard, and this continues to work for multiple reboots. However if I SSH into the machine (which of course is my standard method of working on my servers) it seems to destroy systemd's ability to rename the interface on the next boot. I have played around with the order of the link file numbers to ensure the renumbering doesn't have the devices trying to step on each other, but to no avail. Fixing this problem seems to come down to three different solutions...

  • I can simply touch the eth*.link files and I'm back up afte a reboot.
  • Sometimes I have to get more drastic, actually opening and saving each of the files (without making any changes). WHY these two methods give me different results, I cannot say.
  • When nothing else works, I simply rename one or more of the eth*.link files, giving them a different numerical order. So far it doesn't seem to matter which of the files I rename, but systemd sees that something has changed and re-reads them.

Another piece of information I ran across is that systemd does the interface renaming very early in the boot process, even before the filesystems are mounted, and that you need to run update-initramfs -u to create a new initrd.img file for grub. OK, sounds reasonable... however I would expect the boot behavior to be identical every time I reboot the machine, and not randomly stop working after I sign in remotely. I've also found that generating a new initrd.img does no good unless I also touch or change the link files first, so perhaps this is a false lead.

This behavior just completely baffles me. Renaming interfaces based on MAC addresses should be an extremely simple task, and yet systemd is completely failing unless I change the link files every time I remote connect? Surely someone must have found a reliable way to change multiple interface names in the years since Bullseye was released?

Sorry, I know this is a rant against systemd and this whole "predictable" naming scheme, but all of this stuff worked just fine for the last 24 years that I've been running linux servers, it's not something that should require any effort at all to set up. What do I need to change so that systemd does what it is configured to do, and why is something as simple as a remote connection enough to completely break it when I do get it to work? Please help save my sanity!

(I realize essential details are missing, but this post is already way too long -- ask what you need and I shall provide!)

tl;dr -- Systemd fails to rename network interfaces on the next cycle if I SSH in and type 'reboot'

 

Your dreams and imagination evolved as a view into another universe. As with the current beliefs, you cannot decipher technical information -- no words in books, no details of how devices work, so even if you can describe things you see from another place, you could not reproduce a working version.

Now how do you convince others that the things your are seeing are really happening without being labeled insane? And how could you use this information to benefit yourself or others? Take a peek into the multiverse to see how other versions of yourself have solved these problems...

 

I have a self-hosted matrix-synapse server up and running on a Debian linux server, but before I open it up I want to at least get a captcha service in place to reduce spamming. The only module I've seen to handle this function appears to require setting up a Google recaptcha though, however I would prefer to keep all of this entirely self-contained for the privacy of my users. Can anyone recommend a module that allows for a local captcha option? For that matter, can anyone also recommend a captcha system that is pretty straightforward to set up (which is compatible with matrix-synapse) and uses basic preinstalled code bases like perl or python?

And while I'm here, I would also like to provide the option of registering with an email address, but I'm having trouble finding any clear how-to pages on this. Seems like that function might be built directly in to matrix-synapse but I'm just not finding anything helpful. Any suggestions?

I'm fairly new to matrix in general, but I have an initial setup running with the homeserver, Element web page, and an IRC bridge, so if I can just nail down the validation part of registrations I'll have what I think is a good starting point to launch from.

 

I was reading another article which discussed taking measurements of distance stars at 6-month intervals to create a 3D map of their relative positions and direction of movement. This got me to thinking... has anyone proposed 'dropping' stationary satellites outside of Earth's orbital path for continuous monitoring even when our planet is no longer in that spot? It seems like such an arrangement could provide constant monitoring of things that are happening on the far side of the sun, and they could each act as a relay to each other, bringing the signals back around where we could receive them.

It could be fascinating to be able to constantly monitor the path of know comets, or perhaps even to detect large meteors which are safely away from us now but might some day pose a threat. Studies like mapping star positions could rapidly expand with the availability of continuous data feeds, and I'm sure if such a tool were available scientists would come up with a host of new experiments to try.

A couple other things also come to mind. First off is radio telescopes, which can gather more sensitive data by having sensors further apart. Of course in this case they would only be able to peer in two directions unless you set up the array to rotate as a singular ring (which greatly increases the complexity). The other idea was that I know some phenomena are so large that it takes a huge array of telescopes or sensors to even detect them, and something this large could detect truly astounding low frequency events. Throw in some gravity detectors and watch as the waves propagate through our solar system.

I'm just thinking there's a lot of possibilities here and a lot more data could be collected if we could drop four or eight satellites along the way. I would assume the idea has been proposed before, I just didn't know if this is even feasible?
