It is possible to have backup or failover DNS services, but the very way DNS is designed creates some chokepoints. Long story short, when you want to look up something like "www.twitter.com", your computer has to find out, via a recursive process of asking questions and following the answers, what nameservers provide information for twitter.com. Those nameservers can then be attacked.

You could add more nameservers, but
a) those could just be attacked too: some of the botnets used for attacks now are really massive, and there are various techniques that permit an attacker to punch above his weight, so to speak. And more importantly

b) everything in DNS gets cached for a while. This is actually critically important to how DNS normally functions, because if every component of DNS had to look up every single thing it needs afresh every time, it would be a lot slower and less reliable. So every answer in DNS has a cache "lifetime" attached to it, during which it's assumed to remain valid. If you make changes to how DNS for your site is configured, those changes aren't going to be seen until the cached answer expires. If that cache lifetime was four days (which is pretty standard) nobody is going to see your changes for possibly as much as four days from now. This makes DNS much more efficient, but it also makes rapid changes really difficult.

Very much a bulletin board. Posting stuff for group reference and with possible commentary. Mostly so people aren't forced to scroll through weeks of chat to find certain links and the like.

Yeah, that sounds like a bulletin board use.

So... ergonomic keyboards.

Are they still a thing? And if so, does anyone want to recommend one that works?

So, related:

A few friends and I just split from our gaming group (Malicious Intent) and started our own forum and Teamspeak Server at shark.cafe.

We use phpBB just like Grylliade and it's perfect for us, at about 10 regular users. Good plugins for chatboxes etc.

OK, I just received an email from a sender 'nden'.

The title was 50929 Aresen. There was also an attachment.

Since I do not know who 'nden' is, I assume that something with my email name with a number attached is some sort of spam or malware. Accordingly, I double deleted it without opening it.

Is anyone familiar with any scams in this format?

Yeah it'd easy enough to do with variable fields in mass mailer progs.

If you don't know positively who sent it and that you want to read it, it's either spam or malware and you shouldn't open it, or even preview it (turn the preview window in your email client off, because even that can execute malicious scripts).

That's my general rule. I have heard about the perils of opening or reading unsolicted emails, and that's why I double deleted this one.

To clarify my original post a bit, I was wondering if any of you had heard of a specific scam where the subject line was the email user name plus a number?

It's not really a scam, it's more a general malware spreading tactic, I think.

I want to start using Photoshop to edit and clean up my hiking photos. Which version should I get? Right now, all my images are jpgs from a point and shoot camera, although I'm looking at getting something like a Sony RX100 with raw shooting capabilities before my next long hike.

What do you want to do to them? Photoshop is very often overkill with the proliferation of lightweight (and free) alternatives out there. That said, PS is all cloud now man.

Yeah, it really matters more what you want to do with stuff, and you can probably do whatever processing you want to do with other software. For batch resizing and resampling, I use Irfanview, and for doing more with image composition or content, I use GIMP.

Yeah, but I'm not very good at using it. ;)

Thank you for the input, everyone.

So, here's an example picture from my last hiking trip (completely untouched jpg). Because my pics are taken while hiking, the lighting is dependent on when I get there. This would probably be a great shot at sunset on a day with good weather. I was there at 1 p.m. because I still had 12 miles to hike with a full pack, and it's hazy due to huge wildfires to the south.

I'm not trying to make it look like the aggressively unreal screensaver outdoor pictures that are everywhere, but I would like to clean it up a bit for showing to family. Cropping it to a 16:9 ratio and focusing it on the major peaks and trees helps, but the peaks are still hazy and washed out. If I mess with the colors in GIMP, I can get the trees to a vibrant green, but it tends to make the peaks very blue. If the solution is "suck it up and spend 20 hours getting familiar with GIMP," then I can do that, but if it's easier to accomplish things with Lightroom, then $10 a month is something I'd consider.

Give picmonkey a try. Most of its basic effects are free, and it's pretty easy to use/figure out. I do a lot of simple image processing there and I have yet to run up against anything that it can't do without the premium functions.

If that doesn't work for whatever reason, I'm sure there is a selection of cheapware photo correction apps for your operating system. There's a ton on the Apple app store that do more or less what you want for a one-time cost of five bucks or less.

Does anybody know what to call the tinier version of the 3.5mm audio cable connector? It looks exactly like the 3.5 but slimmer.

It's a "2.5mm phone connector", also known as a 2.5mm plug.

Trying to decipher/weigh the features among high-end point-and-shoot cameras is impossible. I want it for hiking, which filters out many as being too big, but that still leaves quite a few solid options.

Can you just get lens attachments for your phone? It will definitely be less cumbersome, and might be sufficient for your needs.

Well, I've been using a Panasonic Lumix ZS15 for the past 4 years. It's worked pretty well and I have a great case for it. However, it has its limitations, and the mega zoom isn't all that needed for landscape stuff. I was thinking a point and shoot with a bigger sensor (or a huge sensor, like the Ricoh GR II) would be a good improvement (and most would still fit in the case I have). I don't know that a lens attachment for a phone really gets me there.
