Before anyone gets too deep I’d like to point out that this is just about hosting vector tiles, the actual tile gen is a separate project. Not to say that hosting large sets of files is trivial, just that there’s more to the picture than one repo.

My pre caffeine brain though this was chocolate


If you’re trying to get Lemmy to print the backslash, you need to make it a double backslash since backslash is an “escape” character that means “ignore any special formatting meaning of the next character” (among other meanings)


You’d be surprised. My mouse only needs 2.0, but uses a C connector for compatibility. It provides an A to C cable with only 2.0 wiring, which is a decision I assume they made to allow the wire to be more flexible as it can be charged during use or used entirely wired.



Far-UVC has a lot of potential once it’s scaled up. Right now, we’re still learning about best practices.

Institutions should be adopting this tech at scale.

If we’re still learning about best practices why are we talking about deploying this at scale? Self contradictory article…

It should be the other way around. Figure out if it works academically, then test small scale, then scale up with proven and reproducible results. That’s how science works. Best practices can be formulated and adjusted at each stage as more knowledge is gained. That’s how we don’t make a massive health mistake and give an entire convention center indoor sunburns. Especially for people who might be more sensitive to sunburns.


Getting production servers back online with a low level fix is pretty straightforward if you have your backup system taking regular snapshots of pet VMs. Just roll back a few hours. Properly managed cattle, just redeploy the OS and reconnect to data. Physical servers of either type you can either restore a backup (potentially with the IPMI integration so it happens automatically), but you might end up taking hours to restore all data, limited by the bandwidth of your giant spinning rust NAS that is cost cut to only sustain a few parallel recoveries. Or you could spend a few hours with your server techs IPMI booting into safe mode, or write a script that sends reboot commands to the IPMI until the host OS pings back.

All that stuff can be added to your DR plan, and many companies now are probably planning for such an event. It’s like how the US CDC posted a plan about preparing for the zombie apocalypse to help people think about it, this was a fire drill for a widespread ransomware attack. And we as a world weren’t ready. There’s options, but they often require humans to be helping it along when it’s so widespread.

The stinger of this event is how many workstations were affected in parallel. First, there do not exist good tools to be able to cover a remote access solution at the firmware level capable of executing power controls over the internet. You have options in an office building for workstations onsite, there are a handful of systems that can do this over existing networks, but more are highly hardware vendor dependent.

But do you really want to leave PXE enabled on a workstation that will be brought home and rebooted outside of your physical/electronic perimeter? The last few years have showed us that WFH isn’t going away, and those endpoints that exist to roam the world need to be configured in a way that does not leave them easily vulnerable to a low level OS replacement the other 99.99% of the time you aren’t getting crypto’d or receive a bad kernel update.

Even if you place trust in your users and don’t use a firmware password, do you want an untrained user to be walked blindly over the phone to open the firmware settings, plug into their router’s Ethernet port, and add https://winfix.companyname.com as a custom network boot option without accidentally deleting the windows bootloader? Plus, any system that does that type of check automatically at startup makes itself potentially vulnerable to a network-based attack by a threat actor on a low security network (such as the network of an untrusted employee or a device that falls into the wrong hands). I’m not saying such a system is impossible - but it’s a super huge target for a threat actor to go after and it needs to be ironclad.

Given all of that, a lot of companies may instead opt that their workstations are cattle, and would simply be re-imaged if they were crypto’d. If all of your data is on the SMB server/OneDrive/Google/Nextcloud/Dropbox/SaaS whatever, and your users are following the rules, you can fix the problem by swapping a user’s laptop - just like the data problem from paragraph one. You just have a team scale issue that your IT team doesn’t have enough members to handle every user having issues at once.

The reality is there are still going to be applications and use cases that may be critical that don’t support that methodology (as we collectively as IT slowly try to deprecate their use), and that is going to throw a Windows-sized monkey wrench into your DR plan. Do you force your uses to use a VDI solution? Those are pretty dang powerful, but as a Parsec user that has operated their computer from several hundred miles away, you can feel when a responsive application isn’t responding quite fast enough. That VDI system could be recovered via paragraph 1 and just use Chromebooks (or equivalent) that can self-reimage if needed as the thin clients. But would you rather have annoyed users with a slightly less performant system 99.99% of the time or plan for a widespread issue affecting all system the other 0.01%? You’re probably already spending your energy upgrading from legacy apps to make your workstations more like cattle.

All in trying to get at here with this long winded counterpoint - this isn’t an easy problem to solve. I’d love to see the day that IT shops are valued enough to get the budget they need informed by the local experts, and I won’t deny that “C-suite went to x and came back with a bad idea” exists. In the meantime, I think we’re all going to instead be working on ensuring our update policies have better controls on them.

As a closing thought - if you audited a vendor that has a product that could get a system back online into low level recovery after this, would you make a budget request for that product? Or does that create the next CrowdStruckOut event? Do you dual-OS your laptops? How far do you go down the rabbit hole of preparing for the low probability? This is what you have to think about - you have to solve enough problems to get your job done, and not everyone is in an industry regulated to have every problem required to be solved. So you solve what you can by order of probability.


I missed the Photoshop lol…

I’ve been through enough airports with that doggo profile and a similar message I hadn’t considered the possibility it wasn’t some new way TSA was printing their “don’t pet the service dogs” poster.


Isn’t the point of PGP/GPG that there’s no central database?



This elicited a genuine laugh from me.

Excellent work, OP. I can feel the scope creep in my bones.


Absolutely can and will take action. Doesn’t always kill the right process (sometimes it kills big database engines for the crime of existing), but usually gives me enough headroom to SSH back in and fix it myself.


IMO the joke is more “timeless” because it uses state names instead of company names.

Imagine if instead it mentioned Xerox computers, DEC terminals*, IPX, and Ethernet hubs. We’d say “wow that comic didn’t age well”. Even something as recent as “EVGA GPU” will go down in history books instead of commonplace.

*Yes, I am aware that the VT100 terminal spec is from DEC. But they don’t make DEC terminals anymore

10 years down the road, we don’t know what tech will look like. But there is a high likelihood that the state of Pennsylvania will still exist and hold relevance.


Can’t remember if the one I saw was movie or TV but I want to say the plot device in question (from the instance I remembered) was a small acoustic bug under the caps lock key. At the time I thought that was too far fetched to be possible. We live in a world…
