If the only place you are seeing this sort of behavior is Reddit, it's not worth worrying about. If you are so obsessed with what other people are doing on Reddit that you feel the need to ask about it on Reddit/Lemmy, it's probably time turn off your devices and go touch grass. Always remember the Greater Internet Fuckwad Theory. People with pseudo-anominity say a lot of stupid stuff.

On Monday, my desktop monitor decided to die. I sent my computer to restart for updates and it just suddenly gave up the ghost. The power button/light would come up, flicker and turn off, come up, flicker and turn off. The screen itself never came on. Something was very obviously wrong. After a bit of troubleshooting to be sure it was the monitor, I realized that it was no longer working and a suspicious "burning electronics" smell my wife had smelled near my computer recently was probably related.

So, I did what any clueless person does, I searched DuckDuckGo for anything related. And that led me to this video While this wasn't my exact monitor, it was the right manufacturer and with the suspicious "burning electronics" smell, the idea that one or more capacitors had popped seemed possible.

Now, I'm not an electrician. I can solder kinda ok (usually without burning myself). I have a basic understanding of electronics and know enough that I can look at a board and identify some of the components and what they might do. However, at this point the monitor was dead. It was destined for the landfill and I figured, "why the hell not?" The only thing I would lose is some time and maybe I would learn something along the way. And if I did succeed, I'd save myself a couple hundred dollars, prevent more e-waste and just generally do something that made me feel cool. So, I pulled out my toolkit and cracked my monitor open.

Inside I found a setup pretty similar to what the video showed. Specifically, there is a circuit board which is pretty likely the power supply. And sitting in a neat line were three capacitors which were bulging on top. Looking at the traces, all three capacitor bridged the same traces and I'm guessing they work in parallel somehow. I suspect that I had lost one or more when my wife smelled the burning electronics and the last one popped when I did the reboot. The monitor usually cycles into standby and comes back when I reboot and I guess that it led to just enough strain on the capacitor(s) this time to take them out. A few minutes work with a soldering iron, a solder sucker and solder wick and I had all three out and the holes cleaned out, ready for replacements (yes, they were all through-hole style).

Even better, all three capacitors were rated for the exact same voltage and capacitance (680uf 10V). Easy, I'll just pop down to the nearest Radio Shack, grab a few and.... Oh ya, it's not 1999. Getting any sort of small electronics part is actually a bit tough. Well fine, I ordered a 10 pack off Amazon. And then waited for them to arrive. They came today and I sat down to see if I could fix my monitor.

Soldering the new capacitors in place was only a few minutes work. I even have a 3d-printed resistor bending tool to get the spacing and bends in the legs pretty nice. Which was good as I just could not find capacitors of the right rating which were also the same diameter. The ones I got were about 2mm smaller. Parts replaced, I re-assembled my monitor, hooked it back up and... Well, it powered up correctly and the power button/light stayed blue, but there was nothing on the display.

Well shoot, this seemed close, but something was wrong. And then I remembered hearing a "pop" sound while moving some of the control boards around. Maybe I had disconnected a cable by accident or maybe I just didn't reconnect something right, or maybe I just fucked the whole thing up. So, I cracked the case back open (lesson learned: test before reassembling completely). I pulled the control boards back out and sure enough there was a ribbon cable which was half way unseated. I pushed that back in, put the control boards back in place (but left the case open), connected the monitor to my computer and fired it up. Never have I been so happy to see the GRUB menu.

I powered off the monitor, unplugged the cables and closed the case back up. And here I am now, writing a Lemmy post about it, using that monitor. Something destined to be e-waste, saved with less than $10 in components, a bit of easy solder work, and a willingness to just try.

With layoffs starting at WordPress, and me recognizing that I'm a bit of a dinosaur in this regard, I'm wondering what folks are using for self-hosting their own blog these days? While I'm not exactly prolific, I do like having my own little home on the internet to write up things I find interesting and pretending people actually read it. And, of course, I really don't want to be reliant on someone else's computers; so, the ability to self-host is a must.

Honestly, my requirements are pretty basic. I just want something to write and host articles and not have to fight with some janky text editor. And pre-built themes would be very nice. It would be nice if there was an easy way to transition stuff I have in WP; but, I can probably get that with some creative copy/paste work.

So, what are all the cool kids blogging on these days?

On May 8, 1971, a freelance photojournalist was flying over central Vietnam when he looked down and saw something unexpected: A huge peace sign that had been carved into the landscape near Camp Eagle, home of the U.S. Army’s 101st Airborne Division during the Vietnam War.

Fifty-four years have passed since the photo was taken, but the person who created the peace sign was a mystery.

Until now.

If something requires an "app" and a connection to "the cloud" for basic functionality, don't buy it. This sort of abandonment by the manufacturer will always happen. Maybe it will last longer. Maybe it will be next week. But once the company has your money, the last thing they want to do is to spend any of that money providing you with support.

I work in cybersecurity for a large company, which also uses the MS Authenticator app on personal phones (I have it on mine). I do get the whole "Microsoft bad" knee-jerk reaction. I'm typing this from my personal system, running Arch Linux after accepting the difficulties of gaming on Linux because I sure as fuck don't want to deal with Microsoft's crap in Windows 11. That said, I think you're picking the wrong hill to die on here.

In this day and age, Two Factor Authentication (2FA) is part of Security 101. So, you're going to be asked to do something to have 2FA working on your account. And oddly enough, one of the reasons that the company is asking you to install it on your own phone is that many people really hate fiddling with multiple phones (that's the real alternative). There was a time, not all that long ago, where people were screaming for more BYOD. Now that it can be done reasonably securely, companies have gone "all in" on it. It's much cheaper and easier than a lot of the alternatives. I'd love to convince my company to switch over to Yubikeys or the like. As good as push authentication is, it is still vulnerable to social engineering and notification exhaustion attacks. But, like everything in security, it's a trade off between convenience, cost and security. So, that higher level of security is only used for accessing secure enclaves where highly sensitive data is kept.

As for the "why do they pick only this app", it's likely some combination of picking a perceived more secure option and "picking the easiest path". For all the shit Microsoft gets (and they deserve a lot of it), the authenticator app is actually one of the better things they have done. SMS and apps like Duo or other Time based One Time Password (TOTP) solutions, can be ok for 2FA. But, they have a well known weakness around social engineering. And while Microsoft's "type this number" system is only marginally better, it creates one more hurdle for the attacker to get over with the user. As a network defender, the biggest vulnerability we deal with is the interface between the chair and the keyboard. The network would be so much more secure if I could just get rid of all the damned users. But, management insists on letting people actually use their computers, so we need to find a balance where users have as many chances as is practical to remember us saying "IT will never ask you to do this!" And that extra step of typing in the number from the screen is putting one more roadblock in the way of people just blinding giving up their credentials. It's a more active thing for the user to do and may mean they turn their critical thinking skills on just long enough to stop the attack. I will agree that this is a dubious justification, but network defenders really are in a state of throwing anything they can at this problem.

Along with that extra security step, there's probably a bit of laziness involved in picking the Microsoft option. Your company picked O365 for productivity software. While yes, "Microsoft bad" the fact is they won the productivity suite war long, long ago. Management won't give a shit about some sort of ideological rejection of Microsoft. As much as some groups may dislike it, the world runs on Microsoft Office. And Microsoft is the king of making IT's job a lot easier if IT just picks "the Microsoft way". This is at the heart of Extend, Embrace, Extinguish. Once a company picks Microsoft for anything, it becomes much easier to just pick Microsoft for everything. While I haven't personally set up O365 authentication, I'm willing to bet that this is also the case here. Microsoft wants IT teams to pick Microsoft and will make their UIs even worse for IT teams trying to pick "not Microsoft". From the perspective of IT, you wanting to do something else creates extra work for them. If your justification is "Microsoft bad", they are going to tell you to go get fucked. Sure, some of them might agree with you. I spent more than a decade as a Windows sysadmin and even I hate Microsoft. But being asked to stand up and support a whole bunch because of shit for one user's unwillingness to use a Microsoft app, that's gonna be a "no". You're going to need a real business justification to go with that.

That takes us to the privacy question. And I'll admit I don't have solid answers here. On Android, the app asks for permissions to "Camera", "Files and Media" and "Location". I personally have all three of these set to "Do Not Allow". I've not had any issues with the authentication working; so, I suspect none of these permissions are actually required. I have no idea what the iOS version of the app requires. So, YMMV. With no other permissions, the ability of the app to spy on me is pretty limited. Sure, it might have some sooper sekret squirrel stuff buried in it. But, if that is your threat model, and you are not an activist in an authoritarian country or a journalist, you really need to get some perspective. No one, not even Microsoft is trying that hard to figure out the porn you are watching on your phone. Microsoft tracking where you log in to your work from is not all that important of information. And it's really darned useful for cyber security teams trying to keep attackers out of the network.

So ya, this is really not a battle worth picking. It may be that they have picked this app simply because "no one ever got fired for picking Microsoft". But, you are also trying to fight IT simplifying their processes for no real reason. The impetus isn't really on IT to demonstrate why they picked this app. It is a secure way to do 2FA and they likely have a lot of time, effort and money wrapped up in supporting this solution. But, you want to be a special snowflake because "Microsoft bad". Ya, fuck right off with that shit. Unless you are going to take the time to reverse engineer the app and show why the company shouldn't pick it, you're just being a whiny pain in the arse. Install the app, remove it's permissions and move on with life. Or, throw a fit and have the joys of dealing with two phones. Trust me, after a year or so of that, the MS Authenticator app on your personal phone will feel like a hell of a lot better idea.

People being assholes over it is dumb, but I can't say I would want one. I saw one recently at my local grocery store and I couldn't stop thinking how poorly built it looked. It just seemed like the fit and finish of the body panels was kinda bad. I got an overall feeling like it was something put together by a couple of teenagers in metal shop.

The investigation report is going to be interesting. While bridges can only take so much punishment, they are usually designed to survive some collisions with their pylons. I wonder what the state of the bridge was, prior to the collapse. If it's anything like the rest of the infrastructure in the US, it was probably not good. Though, this may also be a case that the designers in the 70's planned for a collision with a cargo vessel of the times, which were tiny bath tub boats compared to the super container ships we have now. The Dali was built in 2015 she is a 300m ship capable of carrying 116851 tons. That's a lot of mass for the pylon and it's barriers to stop.

I recently used Firefox Nightly on my Android device, in a private tab, to login to gmail. After I closed the browser, both via the "quit" menu icon and via swiping the Firefox away in the Overview, I had expected the session information to be deleted and the next time I came back to gmail via a private tab, to be required to login again. However, this was not the case. Despite closing out the browser, something seems to have survived and the I was immediately logged back into the gmail session.

Is this some sort of expected behavior? Shouldn't closing out the browser delete all session information from a private tab? Is there something I missed that maybe I'm not actually "closing" the browser?

Viruses had only been discovered a few decades before this picture was taken. It's very likely that the family (and most of society) had no understanding that the virus was unlikely to jump species and so took the same precaution to keep the cat from spreading the disease that they themselves took. I'd rather people made this sort of mistake than the willful idiots we had this time around refusing to believe in viruses at all.

I'm currently purchasing a new GPU and specifically settled on the MSI 4070 Super. I'm all set for everything except connecting the display to the card.

Currently, the display I have (which isn't being upgraded for now) only has two input options: DVI and VGA. The new GPU only provides HDMI or Display Port. This isn't really a problem as adapters/cables exist to go from Display Port/HDMI to DVI-D.

But, the question I have is, which is the better option, or does it make any difference? And, are there any "gotchas" I should watch out for when buying the cable?

I realize that I am likely over-thinking this, but I would rather ask a stupid question than make a stupid mistake.

Just got started with this game (PC - Steam version). It's fun so far. I had really wanted to use my controller. But, the aiming movement is so sluggish. I've tried pushing the "Aim Sensitivity" up to 10, but still felt like I was turning through molasses. Is there anything which can be done to speed that up, or is the controller just fundamentally slow on PC?

Using an Xbox controller via Bluetooth. And the issue isn't lag, it's the rotation speed in game.

If we could harness the energy of Regan spinning in his grave, we'd have a limitless supply of energy.
Imagine telling any conservative, during the Cold War era, that we could completely fuck Russia's military power and readiness, for years to come, by sending weapons to a relatively small country. They would be rushing to arm anyone and everyone they could, unintended consequences be damned. And yet, here we are with the GOP blocking exactly that sort of activity. And even better, there is a very real possibility that we aren't arming future terrorists this time around. Maybe that's the GOP's problem, Russia losing in Ukraine won't create an excuse in 20 years to kill more brown people.

While it's not my thing, and I view dogs as pets and not food, it's pretty hypocritical to complain about the farming and consumption of dogs for food, while many of us still eat pigs, chickens, cows, turkeys, etc. If Korean culture places dogs on the list of eaten animals and it's done in as human and sanitary condition as possible for farming the animals, then it's not my place to try and stop them.

Good. Tying aid to cuts in IRS funding was absolutely asinine. Failing to fund Ukraine, which is actually fighting for it's continued existence as a political entity is also asinine.

Yes, Hamas is a horrible organization; but, the Israeli Government isn't facing an existential threat and has not been an innocent actor in the situation in Gaza. Aid and support should come with strings attached to ensure the protection of civilians and property rights of the people being displaced.

Ford Motor Co.'s second-quarter profit more than tripled to $1.92 billion versus a year ago (source)
Revenue rose 12% to $44.95 billion

Kinda hard to drum up sympathy for the company when it's raking in almost $2 billion in profit per quarter. Yes, Ford is burning about $1billon per quarter on EVs right now. That's not something the workers should be financing. That's money the company is investing to be viable in the future. That sucks for the shareholders; but, they are the ones who will reap any benefits of that investment and they should be the ones eating the cost.
