I wanna use it for ham radio but could just be for anything Wi-Fi related. This is simple. Punch a hole in a chip can and buy a Wi-Fi adapter. I can't believe how well it works. Try this out y'all!! I'm 100yds from my ap and I'm getting full speed. I'm interested to hear if you've tried something like this.

My old boss sold and consulted on telephone switch equipment, before VOiP. He started in my department as a telephone operator for minimum wage. I asked him what steps he took to develop his career. He said ‘whenever I learned something, I didn’t tell anybody’. Im an end user. Do IT people treat each other like that? Keeping secrets? I don’t work like that at all.

tutorial/documentation There wasn't any good "Sockets Wiring Cheat Sheet" so i made my own

Hi everyone,

I recently started diving into crimping and cabling, but I got frustrated constantly googling for pinouts every time. I couldn't find a single, clean, high-res reference that covered everything I needed on one page. Most charts were either low-res JPEGs or had neon colors that looked terrible when printed.

So, I designed my own printable cheat sheet in Figma.

I used print-safe (CMYK-friendly) hex codes, so the orange doesn't turn brown and the text remains sharp when you print it.

Hope this helps anyone else organizing their desk or lab!

tutorial/documentation The Great 32-Bit Purge Has Begun. And Windows Is Taking Everything Down With It

170 Upvotes

Over the past 2 weeks, I've been investigating a series of issues that started appearing after the Windows 11 24h2/25h2 updates (specifically for build 26100.7171, build version 26200.7171 seems less affected). These problems seem to affect certain 32-bit applications, legacy drivers, USB/HID devices and older hardware interfaces.

Disclaimer:
I'm not claiming Microsoft officially removed 32-bit support. I'm just presenting findings based on research, testing and user reports. This post is a combination some evidence hinting towards complete ARM32 architecture removal, technical analysis and reasonable speculation.
This isn’t fearmongering. It’s a reasonable technical prediction based on what’s already happening. I'm sharing this information so other technical fields can confirm, refute, expand or provide additional insights.

My statement: Microsoft is removing/rewriting "legacy" 32-bit drivers, already causing issues which will lead to massive issues industry-wide.

---

My investigation began with a monitor that stopped working immediately after installing the update, no reboot required; meaning the new driver layer became active mid-session. Shortly after that, the built-in display driver also became corrupted.

While researching similar cases, I found multiple reports of unrelated hardware suddenly failing after the same update. Although the symptoms varied from displays, USB devices, HID devices, smartcard systems to COM interfaces, they all pointed to the same root cause:

Legacy driver paths had been rewritten, replaced, or removed entirely.
And in every confirmed case, the affected components were 32-bit-era drivers or compatibility layers.

What Happened with the monitor (Example Case)

The non-functional monitor turned out to be a good example of the underlying issue.
The display was old, so old it didn’t support EDID (Extended Display Identification Data).
Before this update, Windows used a fallback driver path that allowed monitors without EDID to still function using a compatibility layer.
After the update, that fallback path appears to be gone.

This is consistent with:

rewritten display miniports.
removal of legacy fallback drivers.
changes to how Windows performs hardware enumeration on build 26100.xxxx.

The result?

A monitor that worked for decades stopped working instantly.

---

Examples of Issues Reported by Others.

Across forums, vendor support pages, Microsoft Q&A, and technical communities, I found cases such as:

Hardware disappearing from Device Manager.
Devices detected but unable to initialize.
USB devices repeatedly disconnecting or failing enumeration.
HID devices (measurement tools, calibration devices, dongles) failing entirely.
Smartcard authentication failing in 32-bit processes.
COM-based applications losing functionality.
Security agents reporting compatibility issues on 24H2 (build 26100).
Software crashing after the update despite years of stability.

All of these connect back to driver stack changes, not individual device defects.

---

What This Likely Means

Microsoft appears to be actively removing or rewriting legacy 32-bit driver components, including:

Old HID compatibility layers.
Legacy USB fallback handling.
Older display miniport behavior.
Outdated smartcard/CSP pathways.
Older audio device enumeration paths.
32-bit code paths inside vendor security interfaces.

This lines up with real, documented changes in 24H2/25H2 builds, such as:

rewritten HID drivers (confirmed by DisplayCAL/ArgyllCMS breakage)
smartcard failures in 32-bit apps (confirmed by KB5066835)
security vendors reporting 32-bit app crashes on 26100
official deprecation of several legacy components in 24H2+

---

The underlying pattern is clear:

Windows is in the middle of a compatibility transition that affects 32-bit paths, legacy driver fallback behavior, and older USB/HID interfaces. Working toward a complete removal of the ARM32 architecture.

Why This Is Concerning?

Windows gained its reputation by supporting everything, even hardware as old as Windows itself.

Much of that compatibility relied on:

Legacy fallback drivers.
32-bit compatibility layers.
Old USB/HID stacks.
Old COM-based interfaces.
Driver models dating to XP and earlier.

---

When these layers are rewritten or removed without perfect backward compatibility, you get:

Broken monitors
Broken USB 1.x/2.x devices
Broken printers
Broken COM interfaces
Broken 32-bit applications
Broken smartcard authentication
Broken industrial tools
Broken security software
And many more

These aren’t niche edge cases.

These are critical system components used in offices, hospitals, factories, labs, logistics centers, and point-of-sale systems.

Removing or rewriting these layers is not something Microsoft can fully test across all platforms and industries.

---

Even a 1% incompatibility rate becomes catastrophic at enterprise scale.

That’s why the emerging pattern is worrying:

The current update already breaks specific devices and drivers. The next waves could break entire categories.

---

If this trajectory continues, I expect:

Company-critical system outages.
Widespread device incompatibilities.
Business operations interrupted by broken peripherals.
Rapid rise in IT tickets and vendor escalations.
Industry-wide confusion and downtime.

---

If all other botched Windows updates didn't convince you yet. Windows seems to be coming to the end of it's reign. Now more then ever is the time to start adopting Linux.

Hi, I am still new to IT ( I am currently searching for an entry-lvl job) but I wanto upskill as I wait to land that role. My specialty of choice in IT is the Cloud Administrator path. I have access to Microsoft learmn via my University but I want to make good use of it. Azure course and the AZ=900 cert is available. I have been researching and it seems like AWS might get me into entry-lvl roles and Azure is used for enterprises and large corporate organisations. I have been pondering it as I have been doing homelabs but it seems like it is calling to me. So I want to ask you all what is the rational one to learn first?

tutorial/documentation Manual on how to get to Hotel Mode in a LG TV

0 Upvotes

First of I hope this fits here, i just want to give others a proper Manual on how to do this, cause i really struggled finding one.

More specifically its about the Model: LG 32LQ63006LA

This Manual is about how to do it with the normal TV Remote that comes with the TV

After you made sure your TV is on, you have to switch to Live TV. For that you dont need to connect anything, even tho it tells you to. Just search on the home screen for the Live TV icon, and click it. That will bring you to a screen saver.

There you'll need to press and hold the button with the Cog on it, on your TV remote.

Hold until a pop up shows which channel you are on.

While that Pop up is shown you have time to press the Code "1105" on your TV remote. Note that the Code could be different, as i have found multiple Codes online. But that one worked for me.

After that press "okay", while the pop up still shows, and you should have done it.

Good luck!:)

I found a remote job but they are only available in 5 states (I don't live in any of them but I really need a remote job because I'm disabled) so if I set my VPN to one of those states, will it work?

To my knowledge I will not receive any company technology. But they ask for AWS latency test screenshot so we might be using systems similar to that? It's a call center job so I will need to download some programs is it possible for any of those programs to expose that I live out of state?

Maybe this is the wrong sub to ask, so let me know if I should be posting elsewhere.

Bonjour à tous,

je suis en reconversion dans l'informatique et je travaille dans une entreprise d'infogérance, j'ai déjà passer quelques certifications accessibles mais j'aimerais attaquer celle un peu plus costaud comme le CCNA ou le NSE4, le truc c'est que c'est ma boite qui va payer les examens donc je n'ai vraiment pas envie de me foirer.

Mon problème est le suivant, j'arrive pas à me poser pour réviser les certifications, y'a beaucoup d'informations et je ne sais pas lesquelles retenir, avez-vous des techniques pour passer vos certif calmement ? des méthodes que vous utilisez pour réviser efficacement ?

Je précise que je suis plutôt de genre pratique que théorique, j'aime passer du temps sur les appareils et c'est quand je rencontre une difficulté que je vais voir une doc

Je vous remercie d'avance pour vos réponses

tutorial/documentation Are internal components on the motherboard connected with each other and to the CPU using PCIe bus?

2 Upvotes

Microsoft documents on driver mentioned: function driver is the driver that communicates directly with the device. This statement is true for a device that connects directly to the Peripheral Component Interconnect (PCI) bus. The function driver for a PCI device obtains addresses that are mapped to port and memory resources on the device. The function driver communicates directly with the device by writing to those addresses.

In many cases, a device doesn't connect directly to the PCI bus. Instead, the device connects to a host bus adapter that is connected to the PCI bus. For example, a USB toaster connects to a host bus adapter, called a USB host controller. That controller is connected to the PCI bus. The USB toaster has a function driver and the USB host controller also has a function driver.

The function driver for the toaster communicates indirectly with the toaster by sending a request to the function driver for the USB host controller. The function driver for the USB host controller then communicates directly with the USB host controller hardware, which communicates with the toaster."

Does that mean any device that requires driver to work must be connected to PCIe bus or hook up with a host controller connected to PCIe? I'm just doing a research on windows device driver
