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!

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?

Aww man, I knew it was only a matter of time before someone was going to "force" me to learn python. Thanks for the link, I'll take a look at this after dinner.

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 think my suggestion would be to use the PC as a dedicated firewall, but you will need at least two ethernet ports for that (one to connect to the ISP router, and the second for internal network). This lets you learn network security and control the traffic that can actually get to your other computers. You could also set up KVM to start running virtual machines here. The idea with a VM is to keep services separate and isolated, so like one VM to manage security cameras, another VM to host a game server, another one to host sonarr/radarr/jellyfin... etc.

When you are able to expand, your second physical machine should be your NAS. Get your storage space started, share it over NFS or samba, and move your backup/security camera/sonarr VMs over to this machine for direct access to the larger storage space. Pay attention to system usage and move your VMs to balance the cpu/memory resources. Eventually you may want to get a third machine dedicated more for hosting the game servers, maybe a web server to view the security camera feeds, or whatever.

You mentioned backing up Wikipedia... Have a look at the Kiwix project, you can already get access to regular backups for a lot of information sites.

Don't forget about cops giving gun-safety classes.

I was just wondering how much I could sell them for if they had an actual bullet hole through them...

Meh there was nothing important about him and no reason for anyone to care. On the other hand, there was another school shooting in Evergreen, Colorado, at nearly the same time, and THAT is what everyone should be focusing on. Of course the cantaloupe in charge still hasn't said a word about THAT because he couldn't make that tragedy about himself.

I guess this is how they solve their food shortage after getting so much blowback from trying to force children to replace migrants working in the fields.

 

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.

 

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...

 

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?

 

I run my own email server, and a friend received a compromised laptop from work which resulted in a spam attack from Russia yesterday. Turtle settings saved the days with thousands of emails still in the queue when I saw the problem, however it made me realize that everyone with accounts on my server are local, do not travel, and have no requirement to send emails from outside the country.

I found how to use the smtpd_discard_ehlo_keyword_address_maps setting in postfix to block a CIDR list of IPs, then found a maintained list of IPs by country codes on github. Cool so far, and a script to keep my local list updated was easy enough.

Now the question is, what countries should I be blocking? There are plenty of lists of the top hacking sources, but it's hard to block #2 (the US) when that's where I am located. But otherwise, does anyone have a list of countries they outright block from logging on to their servers? From the above google searches I have 17 countries blocked so far, and in the first 30 minutes already stopped login attempts from three of those countries, so it appears to be working.

Of course I could write a script to parse my logs to see who has already made attempts, but that's what services like fail2ban are for, and I'm just wondering if there are any countries in particular I should directly block? My list so far includes the following: ae bg br cn de hk id in ir iq il kp ng ru sa th vn

The question itself may not be that interesting, but I thought at the very least some folks might be interested in my experience and think about doing something similar themselves. I can post more details of what I did if there is any interest.

 

I have Openfire set up with the monitoring service plugin which we have been using with Pidgin on the desktop. One of the things I've noticed is that when I sign in to another computer on the same account, I do not get a history of recent messages (which I thought the monitoring plugin was supposed to provide).

The other thing that doesn't seem to be working right is when I am logged in to two computers simultaneously (using the same account). I expect to see chat messages showing up on BOTH devices so I can go between machines, which again is something I thought the monitoring plug was supposed to provide.

The settings I believe are related are under "Offline messages" which I have set to always store, and retain for up to 30 days. Should I bee looking for anything else?

I have been using Pidgin with XMPP on Google for years, so I know both the XMPP protocol and the Pidgin client are capable of handling this functionality. I've been digging around trying to find a solution, and see a lot of things claiming Pidgin is the culprit here, but those messages are a decade old. I can't seem to find any information on the subject for Openfire newer than about 2016.

I'm hoping there's a setting I need to change or another plugin I need to add to get both of these features working on my server? I really love the software otherwise but this seems like a really basic function that should just work, and I am hoping someone can point me to whatever I'm missing.

 

I just started noticing this happen today. For example I was reading posts in the mycology community and posts from comics started appearing at the top of the page. I'm assuming this is a bug but is there anything I can do about it from my end, or do I just have to wait for the next update? FYI I'm just on the desktop browser, not using any apps.
