I guess I’ll let people know I have a Patreon in case anybody feels like contributing to it. I never liked people asking for donations, so I’m not... but if anybody feels they would like to help support my work on Elucubratus etc, this is available for you patreon.com/sbingner?utm_m…

When your Mac connects to a network, it first checks if the name it wants is taken in mdns by sending a broadcast DNS query. If it is taken, it tries again with a different name until it finds one that's free. Avahi on Linux and Bonjour on MacOS handle RFC 6762 nicely
Jamie Birch@birch_js

I connected to some WiFi and macOS alerted me that it had had to rename my Mac from "MacBook Pro (2)" to "MacBook Pro (3)" due to a name clash on the network. But why was my Mac the one that got renamed? There must be a hidden heuristic to decide which is the dominant Mac.

@ajzeigler My kid was using TTS on his reading assignments from school because they have everything on the computer. Can we just stop using computers for school assignments that can be done better via pen and paper please?

@davepl1968 I’d check processor utilization. You may be handling the download on all cores but the upload could be limited. I have seen that on various network drivers, but that was generally limiting to more like 5Gb instead of 9Gb, maybe your single core it’s stuck on is faster than mine

Does anyone know why, at all defaults, I'd get 25Gbe in one direction and 10Gbe in the other direction? Same transceiver on both ends (25Gbe fiber 10GTek)

Every time I post about our family getting split up on a flight I’m told I didn’t pay enough for our seats or book far enough in advance. But this is what Macaulay Culkin just posted. It should not be legal for airlines to split up kids and parents on the same reservation.

@DMVAdventures @dontfacetimeme You can’t use an airtag until you pair it, ergo he could not use this airtag. The battery isn’t even connected in the packaging.

Dear @DoorDash, First, Dmitri is my legal name, but please, call me Misha. Second, thank you taking the time to rectify this important matter! Since you are a delivery service, I think it would be easiest if you just had a driver deliver 10 cents directly to my home. Thanks in advance for the dime! -Dmitri (AKA Misha)

@CyberRacheal Yeah you can boot GPT partitions using legacy BIOS just fine. It just uses a GPT/MBR and a boot partition addressable from the MBR overlay. Then the OS uses the space, really no difficulty.

UEFI is the modern successor to the Legacy BIOS, serving as the firmware interface that bridges a computer's hardware and its operating system during startup. While Legacy BIOS is limited to the older Master Boot Record (MBR) system, which restricts partition sizes to 2TB and allows only four primary partitions, UEFI utilizes the GUID Partition Table (GPT) to support significantly larger drives and more partitions. UEFI also offers superior performance through concurrent hardware initialization for faster boot times, enhanced security via the Secure Boot feature to prevent unauthorized code from running at startup, and a user-friendly graphical interface that supports mouse navigation, unlike the text-heavy, keyboard-only environment of traditional BIOS.

@devahaz The one that boggles my mind is when checking in and they offer free gate check for roller.bgs because there will be limited room and people don't immediately accept. You won, you get to check your bag for free and not have to haul it around.

@magagoals @CyberRacheal I mean if you randomly throw NAT in and ignore the giant red flag - it could be ARP or DNS just as easily as NAT. Some idiot configured the network to actually use these addresses and a static ARP entry on your router got added for this pointless address or dns server is down.

@CyberRacheal better. probably c) though that only covers machines that leverage it, not those with static ips. Also... 169.254.x.x can be used for a local network.... so b) could also be the answer

@CyberRacheal You’re oversimplifying. That delay also can cause TCP to throttle your connection down to <1Mbit - but they do generally have TCP acceleration devices to work around that. The round trip delay is approximately 640ms or just over half a second minimum.

The lag you feel is due to the extreme distance your signal must travel; most in-flight WiFi uses satellites orbiting 22,000 miles above Earth. Every time you click a link, your request performs a double round-trip, traveling from the plane to space, down to a ground station, and back again, which, even at the speed of light, creates a massive delay before the webpage even responds. Once that initial handshake is finished, the bandwidth takes over like an open firehose. While the speed limit for a single bit of data is slow due to the distance, the width of the connection is actually quite large, allowing thousands of image pixels to pour into your device all at once.
Cyber_Racheal@CyberRacheal

Interviewer: You’re on a plane using "In-Flight WiFi." It’s usually slow. You notice that web pages take 10 seconds to start loading, but once they start, the images fly in pretty fast. Why is the start of the connection (the Latency) so much worse than the speed" of the download (the Bandwidth) in satellite networking?

@NoiseesoiN @rudy_betrayed Well no, but that’s not because of how you signed it. Writing something on a document as a signature is a signature if they can prove you did it. It may not be legally binding for the reasons you said of course.

@sbingner @rudy_betrayed It's not a legally binding signature unless it's to something legally binding. Nurse: "We have a signature we're calling 'legally binding' even though we never actually handed over the document to sign, and I'm pretty sure it was signed by the person we claim."

Was at the doctor today. I was asked to sign a “lifetime consent” form on the little digital signature pad Uh can I read what I’m signing “We usually don’t print it out. It’s on your MyChart app” Open my app right in front of her and show her there’s nothing there “Ok well my printer isn’t working right now. You have to sign it to be seen today, or else we can just reschedule you” So I scribble on the pad and hope I didn’t just give them the title to my car or something

Does anyone else get asked to sign things at the doctor's office that aren't true? This is the second time. J is getting allergy shots, and the nurse says "I need you to sign this." I read it, and it says "I confirm we are leaving the premises despite being advised against doing so." I say "but we aren't leaving. You just told me we should wait here for 20 minutes, and we are." At the pediatrician: "we need you to sign this Good Faith Estimate. " Me: "I don't see the Estimate." Receptionist: "That is the Good Faith Estimate" Me: "... there is no number. If I sign this, you can charge whatever you want and I have to pay it. That seems contradictory to the purpose of GFE" Receptionist, now annoyed because how dare I read: "do what you want but they won't treat her if you don't sign and you'll pay a cancelation fee" How is this legal?

My dad (retired journalist) hated flowery language so much that he made me promise to say he died in his obituary (as opposed to succumbing to an illness etc). Then when he died when I was 26 I had to argue with the funeral director about how cold my obituary sounded, lmao.

Password rotation or Forced changes lead to "password hedging," where users just add a number or change one letter (e.g., Summer1! becomes Summer2!). It is biologically impossible for most people to memorize a high volume of complex, random strings every few months, leading to "sticky note" security risks. When security is a hassle, users find dangerous shortcuts, like reusing the same "strong" password across every site they own. The most important fact is that NIST (National Institute of Standards and Technology), the global authority on cybersecurity standards, officially retired this method In its Digital Identity Guidelines (SP 800-63B), NIST now explicitly states that organizations "SHALL NOT require" periodic password changes. They’ve shifted the focus to Length over Complexity. They recommend allowing passphrases of up to 64 characters and only requiring a change if there is actual evidence of a compromise.

Password rotation every 90 days actually makes your company LESS secure. Change my mind.
