InvaderFizz··on Apple's Pro Display XDR takes Thunderbolt 3 to its limit
Most GPON is quite thin. Thinner and tougher than standard fiber patch cables.
InvaderFizz··on Ethernet Is Still Going Strong After 50 Years
Worth trying on a shorter run of CAT3, yes. Worth trying on a standard untwisted two pair phone line? Nope. Good luck getting even 5meters.
InvaderFizz··on Is the Intel N100 a better option than high-end ARM RK3588 boards at the moment?
There is a reply at the end stating it works with 48GB DIMMs too.
InvaderFizz··on FCC wants to bolster amateur radio
Out of curiosity, do you happen to know what kind of throughput we could expect on a simplex 2.8/2.5khz carrier? Assuming something like -75dbm SNR. I'm not familiar with anything modern that does bandwidths that small.

I ran the calculations for LTE in a FM radio station allocation a few years back and came up with something like 1.4Mbps on a CAT4 radio (no idea what modulation and FEC levels I assumed).

InvaderFizz··on Tell HN: Automatic fraud detection is making my life hell
I've had the best luck sticking to ApplePay, PayPal as the backup, and finally my CC (the Apple Pay one).

I can't think of a payment hurdle for online purchases that I haven't been able to overcome in the past year or two while spending 99% of my time OCONUS.

InvaderFizz··on The Darién Gap
Don't drive at night and don't look like a soft target solves most issues with traveling in Mexico.

I've driven the entire Baja peninsula many times and done a road trip across much of central Mexico.

InvaderFizz··on FPGA N64
No. The GitHub link is to Mister64. Which is an impressive WIP, but is not related to the main article linked here.

I'm most excited for the next generation of FPGA retro consoles coming in the next 6ish months. Specifically the MARSFPGA. All the existing Mister cores, plus a bunch of new stuff enabled by a better and newer FPGA. The estimated price is $700, that's reasonable for those of us with large disposable income that want the retro kit with no hassle, easy access for the kids, and high Wife Acceptance Factor.

I'm also looking forward to all the upcoming arcade cores for the MARSFPGA.

InvaderFizz··on Ask HN: Did you change career paths after 30?
My DevOps world revolves around IaC to support developers and their products. Pipelines, terraform module development and upkeep, security reviews, threat mitigation and static code scanning, keeping all the infrastructure up to date and everything within current and supported software versions. Most of what I do code wise is terraform and python. Operationally, I'm the guy that comes in to RCA all the weird edge cases. That is the most fun part of the job for me, constant dopamine hits in solving issue that have been plaguing others for weeks.

The easiest way to 10x is to work 80 hours per week, but make sure you get paid for 80 hours per week, not just 40. I'm a workaholic, so I've been doing that for years on end.

I work multiple C2C contracts and make sure that the work that I do overlaps heavily between clients. I only take on clients that are all in on terraform and lean heavily on AWS managed services. With those two keystones in place, the value I can provide clients is far in excess of what they normally would get because I get to see it all. I run into an issue at Client A, and I put things in place at Client B to mitigate that issue before it even occurs. The DR solution I design for Client B is mostly copy/paste for Client C with minor adjustments and all the lessons from having just completed a DR failover test for Client A.

InvaderFizz··on Ask HN: Did you change career paths after 30?
Yes. I spent about 10 years doing military Satellite Communications, took a year off after a few years in the sandbox. I then switched to IT. Pivoted from Sysadmin to SRE/DevOps five years later.

Five more years after that and I make 10x what I did 10 years ago and am working towards FIRE. My family lives on <30% of my income, the rest goes to savings and investments. We should reach our FIRE number before I turn 50.

I love the work I do (DevOps with a Security focus), and that year off I took I was miserable. I'll probably never really retire, just be to the point where I can do the work I need to in under four hours per day and travel.

InvaderFizz··on Raspberry Pi 5
The N100 is quite good all things considered. It generally beats an i5-6500t in pretty much anything while having very low power draw and all the newest media engine encoders.
InvaderFizz··on Burning money on paid ads for a dev tool – what we've learned
In the vast majority of cases, these creators are only taking slight liberties with talking points provided by the advertiser.

If basically every NordVPN ad on YouTube is talking about safety, you can be fairly confident that it was a talking point provided by NordVPN.

InvaderFizz··on The triumphs and failures of accessible gaming hardware
An easy selling point to at least start is that universally using accessibility labeling makes automated app testing phenomenally easier to write and maintain.
InvaderFizz··on Hookworm gave the South a bad name (2016)
After the elimination of hookworms, air conditioning is what really made the difference in the south when it comes to economic development. Those summers are oppressive.

Anyone who grew up in rural areas of the south is generally on the lookout for chiggers, ringworms, ticks, hookworms, and pinworms.

InvaderFizz··on SpamChannel: Spoofing emails from 2M domains and virtually becoming Satan [pdf]
I thought it already was required and if you specify adkim in your record.
InvaderFizz··on Unix shells are generally not viable access control mechanisms any more
Yes.

TFA = The Fucking Article.

Much like:

RTFM = Read The Fucking Manual.

InvaderFizz··on Microsoft to kill off third-party printer drivers in Windows
Yes, easy to turn off. This post prompted me to turn that off, I had neglected to do so last week when I set it up.

- Network, Advanced, WiFi Direct, off.

InvaderFizz··on Bare-Metal Kubernetes, Part I: Talos on Hetzner
I'm going through you series now. Very well done.

I thought I would mention that age is now built in to SOPS, thus needs no external dependencies and is faster and easier than gpg.

InvaderFizz··on Google, Meta, Amazon hiring low-paid H1B workers after US layoffs
This is the only part of the article that matters, and even it is a stretch:

> Just a month after Sundar Pichai announced Google’s plan to cut 12,000 jobs around the world in January, the company filed applications for H1B visas to hire software engineers, analytical consultants, user experience researchers and other roles from outside the United States, with several requests aimed for new Google employees to join in August, the report states. Google parent Alphabet owned Waymo too has reportedly filed similar H1B applications to hire engineers.

The article fails to mention and actual H1B requests by the others, just lumps them in with the layoffs.

InvaderFizz··on On the 10th anniversary of the Snowden revelations
This is a rather strange take. In 2013, Hong Kong was a very different place than today, with none of the China stigma.

Additionally, you neglect to mention that is was the US actions in cancelling his passport that stranded Snowden in the Moscow airport that he was transiting through on the way to Ecuador.

InvaderFizz··on Spotify looked to ban white noise podcasts to become more profitable
Turn off silence/vibrate only mode on your phone. I leave mine in vibrate mode 99% of the time, so I expect this to happen occasionally.
InvaderFizz··on Timing with Curl (2010)
That's really cool. TIL.

Also, curl can talk ftp, upload and download. Which is super useful when dealing with legacy things.

InvaderFizz··on Leave It to the Beavers
There is a really great podcast episode[0] about beavers and their long term impact. The TLDR is that beavers are prolific terraformers and much of the western landscapes and weather we take for granted are the direct result of beavers. I certainly came away from this episode with a new respect for beavers.

InvaderFizz··on Source code for Quake 2 rerelease
Yes. Very difficult to play with a mouse, but the pros with a mouse were amazing. I had a few friends that were mouse players.

The most popular choice of accessory was the Sidewinder 3D Pro. That was my choice of input device and I was easily a top 5% player in my teens.

I never touched one, but many people swore by the SpaceOrb 360 as the pinnacle of controllers for Descent.

InvaderFizz··on Archive of novelty answering machine recordings
Fantastic, really takes you back.

My own voicemail has been degraded to being the "We're sorry, the number you have called has been disconnected" recording on loop to discourage spam calls. It works, but is not great when I'm getting a call from someone I don't know but would find the voicemail useful for.

InvaderFizz··on Threat Actors Abuse Cloudflare Tunnel for Persistent Access, Data Theft
In Cloudflare's case they specifically do tunnels on port 7843. Just block TCP/UDP outbound on those pots and CF Tunnels won't work.

InvaderFizz··on Musl 1.2.4 adds TCP DNS fallback
DevOps/SRE. Our technical interview is pretty regimented and cookie cutter. Over the course of one hour we cover a wide base of practical knowledge to validate the candidates existing knowledge or their ability to quickly acquire the needed knowledge (use of google/stack overflow is encouraged).

As an icebreaker, I pick out items from their resume that stand out and look like strengths. My goal is to play to those strengths and get them comfortable talking about their past battles.

InvaderFizz··on Musl 1.2.4 adds TCP DNS fallback
It's still going to be pretty common for at least a few years, and the now incorrect assumption that it is still broken I'm sure will persist for a decade or more among those who have been burned and thus moved on from Alpine and do not follow it.

DNS is a fun rabbit hole for interviews, for sure.

My favorite one to see on a resume is NIS. If you are listing NIS and don't have horror stories or other things to say about NIS, that's a really good indicator of the value of your resume.

I intentionally list NIS on my resume because it is such a fun conversation topic to go on about how security models changed over time, all the ways NIS is terrible, but also how simple and useful it was.

InvaderFizz··on The power of weeds to end hunger in an uncertain climate
Probably as a result of where I grew up (rural southeastern US, 20 miles from the closest population center over 1k people). But I have never considered dandelions to be weeds. Just another interesting plant in the multitude of grasses that made up our 3 acre front yard.

Clover, dandelions, crabgrass, dallisgrass, etc were just part of our yard. We also used it often as grazing for the horses as an alternative to spending hours mowing every few weeks. So any attempt as species control would have been undone by the horse manure anyways.

InvaderFizz··on Musl 1.2.4 adds TCP DNS fallback
Glad to see this finally come to fruition.

This has been an issue plaguing Alpine for years where the musl maintainer basically said the standard says may fallback, not must fallback. Let the rest of the internet change, we don't feel this is important. We're standards complainant.

It gained traction for the change with the latest RFC. for dns last year which made TCP fallback mandatory [0]. The cloak of standards compliant could no longer be used.

InvaderFizz··on 2,500 continuous runtime hours on a 4.77Mhz DOS web server
WinAmp + Windows 98 on a DX2 66.

Now, if you did anything on the computer other than let WinAmp play without the flame graph, it would stutter. I had the machine under my desk and used VNC to connect to it and change tracks or whatever.
