I've been the sole developer for my company's website for over a decade now. It's gone through a bunch of evolutions throughout the years, but I've been sidetracked lately and have let things stagnate as far as maintenance goes. Now, I'm looking to do some upgrades for security purposes and I'm trying to wrap my head around everything.

Some facts:

• PHP 8.0.12
• MySQL 5.7
• Symfony 5.4
• Web server is currently Apache only because that's what I've always used. I'm open to nginx or other options.
• Running on a Google Cloud VPS with Ubuntu 20.04
• I also use Google Cloud Storage to host thousands of images

My first thought was to take baby steps and start by upgrading Symfony as much as possible. However, the next major version (6.0) requires PHP 8.0.2. Symfony 6.1 requires PHP 8.1. Symfony 7.2 (the current release) requires PHP 8.2. So, then it just makes sense to upgrade PHP to the latest version.

However, I am terrified of upgrading PHP in the current (outdated) Ubuntu environment. So I might as well upgrade the distro while I'm at it.

And then, MySQL 5.7 is no longer supported, so I might as well bring that up to date too (8.0, I believe).

There will be no baby steps. I'm gonna have to just upgrade everything all at once. Which then leads me to my next question: should I stick with the self-managed VPS, or is it time to look at something like Google App Engine or Fly.io that is a little bit more managed and "locked down" than what I'm doing right now? Should I look into just going with Docker instead?

Put another way, if I'm going to start from ~scratch, what's the modern best practice to host all of this, given that I'm going to have to upgrade a bunch of different things all at once? (Turns out the "baby step" of upgrading Symfony will actually have to come last since I need to hit these prerequisites first).

Please let me know if I've left anything out. PS, security is a pretty big concern for us because we manage user auth, so I'm all for anything the cloud providers can do to take some of that responsibility away from me.

I’m working on an “advice” blog post for tech people at companies that plan to abandon VMWare. The idea is to give the reader an idea of what to expect and to help them plan their migration. The article will be on a vendor site, but I’m writing it with editorial purity. The only promotional component is at the end, where we say, “We can help with that!” and link to a white paper or whatnot.

So, what should I include in this listicle? What advice is important to impart – and why is that important?

References and examples are welcome. Horror stories are good, too. I’m not planning to quote anybody by name so don’t be shy. (I don’t need to explain why they plan to drop VMWare. Nor will there be a discussion about possible replacements. This is a process story that happens before you choose a replacement product/vendor.)

I want something like typingmind but for free, and that doesn't require installation. mainly for gemini and mistral (or perhaps groq too) I just want to be able to paste my API key and just use it. I know about OpenWebUI and msty but OpenWebUI requires installation, and msty doesn't have an android version.

anyone know something like this ? (would also be nice if it supports LaTeX)

Good evening, everyone. I was wondering if any of my fellow Tilders had experience with using Android's Private DNS feature on unconventional android devices e.g. WearOS, Android TVs etc.

It was quite easy to figure out exactly how to set up an alternative DNS server on these devices. By default, Google has hidden the private DNS setting on them, but it is still accessible from ADB. In both of my examples it is likely easiest to enable “Wireless Debugging”, pair the devices successfully, and then run the commands.

settings put global private_dns_specifier one.one.one.one (replace this with the pertinent server!!)
settings put global private_dns_mode hostname

The issue I have been running into, however, is if there is seemingly any form of content filtering enabled on the DNS server of your choice, the WearOS device seems to think internet is unavailable when first connecting. If you open the Settings app and leave it open for long enough on the Wi-Fi page, it will switch from “Internet not available” to “Connected”. Contrary to this, if you open an app like Samsung Internet for, it does not take this time and just refuses to use any configured Wi-Fi network.

To go into my specific situation in a little more detail, I use NextDNS configured with Hagezi Multi PRO++ block list. I have no issues on my S24+ with regard to internet being deemed unavailable by the OS (sure the occasional public Wi-Fi network blocks DoT—I just use mobile data then). I have also yet to try it on my Smart TV, which is frankly the more important target device than my watch (I will get around to it in the new year once the holidays are over).

This is all a potentially very convoluted way to ask what people's experiences are with this, and if they have faced similar problems to me when using providers like NextDNS, AdGuard etc. that provide content filtering options on their encrypted DNS connections.

Merci beaucoup !

I bought a cable modem off of eBay. I have contacted the seller.

When I turn it on it sounds like I am listening to a helicopter at low volume. Thumping noises.

I DDGed. It isn't electronic interference. It is on the same spot of my desk that my old cable modem was on.

I'm not sure I can open it or not, but the case has many holes. I may try running the hose attachment from my vacuum cleaner over it to try to get dust out.

Anything else I can try?

I've been having intermittent problems with selecting text. I'm not sure which software it is in, but it is certainly in Slack and IntelliJ. The text I select will often/sometimes not stay selected once I lift my finger up. It will take several times to make the selection last, sometimes swiping in a different direction.

Is it my mouse or the software?

My mouse in made by Inland, model RTM098( J10 ). Probably very old.

While I consider this resolved at time of posting, this is one of my weirder, more unexpected tech issues I've run into and I thought y'all might enjoy it.

I'd been having issues with my (Ubuntu) server where its services were unavailable, I couldn't SSH in, and USB devices plugged in after the issues started weren't connecting (mouse LED would light up, couldn't toggle keyboard locks or interface computer with the devices). These issues were becoming a near daily occurrence.

So after the most recent incident I decided to watch it boot. After grub, it would just hang at a black screen. So I opted for the recovery mode and after waiting some minutes for services to time out, I was given a terminal and used that to check my devices, sensors, etc and all were reading fine.

Frustrated, I started reviewing what else could have possibly changed with my setup, and I found that change in my hand. I use my server's front USBs as a low current charger and had recently got a new vape battery that was charging at that moment.

I unplugged the battery, rebooted, everything was fine. Plugged the battery in, everything locked up again immediately.

I had been using a spare cable, it had data wired. Swapping for the included power only cable, and no issues.

While I'm curious as to what exactly is happening and why, I'm satisfied enough concluding it is a cheap vape (I mean, I'm having to charge the sucker near daily after all) that is transmitting junk over data and the OS doesn't handle it appropriately. I'll pull logs or do another couple tests if other folks are curious as well though.

Oh, and the battery is a Bear Rootz Sol. Come to think of it, my other worst battery at holding a charge was also a Bear Rootz.

By "modern-ish" I mean support for wifi, USB, etc. Maybe modern is the wrong word, but "not prehistoric" fits better? I primarily want to use these machines for some old school mudding. Bonus points for a browser that works with encryption to make web browsing somewhat usable.

Computer #1: "Ole trusty"

This one came with the OG Windows NT. I've toyed with FreeBSD installs from version 4 to 7 or so. Right now I believe it has Windows 95 or 98.

• Compaq / Pentium
• 3.25" disk drive
• Broken CD-ROM and I haven't found a plug-and-play replacement yet, even though I've tried 3 or 4. I can get it to work by forcing the tray open and closed, but I'm certain the tray is going to snap soon.
• I've replaced the hard drive with a compact flash
• Right now it has a PCI LAN adapter, but I have the option to replace this with a wifi adapter (Linksys I believe)

Computer #2: "MTV was still cool"

This one's running Windows 3.1 at the moment. It's going to be much tougher to get a network connection going. Is it possible to do some sort of modem-to-wifi bridge?

• Compaq / 386
• 5 1/2" and 3.25" disk drives, no CD ROM
• Compact flash HD
• It has a modem, I'm not sure how fast. I'm also not sure how many expansion slots are left.
