- Comment on Automatic Fire Extinguisher for 3D Printer Cabinet 1 month ago:
I have the spheres. I of course, for science…, tested one over a small garbage can fire I set purposefully. It worked way better than I thought it would. I have one in my server racks, multiple ones over my mining equipment, and did have one over my older 3d printer. The miners are the only thing I think would ever actually catch fire.
- Comment on How do you build complex shapes? 1 month ago:
You use a real CAD program. The free tools can get you pretty far and are great for basic stuff. But as you’re learning, once it’s not basic, it’s not a problem for a free shitty tool to solve.
It becomes a problem for a very expensive shitty tool to solve, like Solidworks.
Designing those things that slide into each other and everything on non perpendicular planes is child’s play in SolidWorks. The slide in feature assuming they are mates is basically 3 button clicks and 10 seconds. Bam, done. Weird angles and planes, super easy.
You pay dearly for such ease. But that’s how it’s done. If you can’t afford a trial or a student copy or a used copy, then there are ways. But a SolidWorks DVD from 15 years ago will do everything you want it to. CAD doesn’t change much. And if you don’t need super fancy 3D photo realistic renderings and the ability to import PCBs and thermodynamic simulations, than a 15 year old almost free copy of a powerful tool will beat any modern free tool.
- Comment on Doesn't the need for a permit fundamentally contradict the US's ideals of free speech? 1 month ago:
EVERYTHING you do in the USA is illegal. This is not hyperbole.
Any right you think you have is stripped by another law also on the books. You are always and forever in breach of the law. This allows you those with no education and power like police and DAs to pick and choose who and what to prosecute. If everyone is in breach, it doesn’t make it legal. It just makes it a game of “don’t piss off your oppressor”. This is the same game used in North Korea. Same in the USSR. Same in many fascist nations with an illusion of democracy.

Similar useless everyday objects sitting in a museum today from less time ago that we pay money to stare at. Heck there’s a Walkman in a museum…
- Comment on Motherboard makers apparently to blame for high-end Intel Core i9 CPU failures | Ars Technica 1 month ago:
Oh but you are. It’s at 0.8v to 1.2v range so it’s high current.
This is what all the VRM design is for. The motherboards are generally 20-30 layers nowadays with 2oz copper in the power layers. The traces are short and you do get hundreds of amps.
And yes, I’ve designed them on the silicon side.
- Comment on Not happening, dude 1 month ago:
This is an acceptable excuse in 1902.
In the age of Google and where even the homeless bum down by the river has a smart phone, Googling to find out about a major life choice is easy to do. Failure to help yourself do nothing but use a phone for 10 minutes deserves zero empathy.
- Comment on Not happening, dude 1 month ago:
If “ignorance isn’t an excuse” doesn’t get you out of any law you break, it also doesn’t get you out of accidentally joining a terrorist organization due to propaganda.
Because that’s exactly what it is.
It is no different than the teenagers that join ISIS. Propaganda takes them in, they join voluntarily, they live with their consequences for life.
- Comment on Not happening, dude 1 month ago:
If they weren’t conscripted via draft, they volunteered. 100% their shitty choice to become a terrorist.
- Comment on Lawmakers vote to reauthorize US spying law that critics say expands government surveillance 2 months ago:
Fascists will fascist. The US is no different than China to anyone paying attention. Except your people get none of the benefits that the Chinese do like modern and clean cities and infrastructure, lower cost of living, low crime, etc.
- Comment on Which of these VPS providers would you recommend? 2 months ago:
I use World Stream for many of my storage VPSs. They have pretty cheap servers that can take 14x or 18x drives. So I use their super powerful Epycs plus storage and then they can do an internal LAN only network for your boxes at 10G. 140TB to 200TB per box, connected to the rest of my stuff at 10G.
Their support is opposite of Hetzner. Everything is communicated. It’s almost too much. You get emails that they’re updating the air conditioning unit in a different building. Your downtime is zero. I’ve had some questions on setting up my rack space with them, and engineers respond back, not sales.
- Comment on Which of these VPS providers would you recommend? 2 months ago:
You know what sucks? Getting your VPS shut off or account suspended. All your data gone in an instant, not recoverable. You don’t have access to the metal, and the metal no longer has access to you.
Hetzner is known for randomly boinking accounts. You update billing info? Whoops maybe shutoff. You login via a VPN, account disabled. Just randomly for no reason, account locked and VPS down.
You have basically zero recourse. Their support staff suck and the immediate reaction is suspend and delete. NEVER use them for anything you don’t consider temporary.

I’m never going to financially recover from this.
- Comment on i have a problem with USB c charging 😅 3 months ago:
That looks like a really simple USB C port in legacy A (with DP/DM charge signals) configuration. The single IC most likely does the USB negotiation and the CC/CV charge of the battery.
Often these devices are tightly coupled with the USB state machine. Just applying 5v without terminating the sense resistors won’t do anything.
Also be very careful with Qi chargers. The resonant circuit produces voltage spikes in the tens of volts. It is usually regulated and smoothed to 5v out. But it’s also very bursty. Make sure your output circuit after the coil is fully regulated 5v voltage. I’ve seen them be varying voltages and even current mode outputs.
- Comment on What games do you replay regularly/annually ? 3 months ago:
Starcraft. Not 2, just StarCraft.
And sometimes Command and Conquer Red Alert in the emulator.
- Comment on Why are mental hospitals run like prisons? 3 months ago:
Because it’s cheaper. If this is in a country where you or your family can sue because of a liability of the private institution or public one, then they treat everyone as a threat. Doesn’t matter why you’re there, you have to be treated just like the psycho Hannibal. Because if you turn out to be like that, and they didn’t screen you “for your safety and the safety of the staff”, it would be lawsuits galore.
- Comment on Mozilla lays off 60 people, wants to build AI into Firefox 4 months ago:
I desire the browser to work as well as it did a decade ago. It worked perfectly all the time. Now I’m task closing it once every days because an entire window just goes blank white and never context updates. The CPU usage randomly spikes super high. It eats RAM uncontrollably and seemingly never releases what it should and holds on to what it doesn’t need forever.
I don’t need AI. I need a good browser. And many of these issues are Chromium and why I switched from Chrome long ago (which I had switched to after FF broke all the extensions 20 years ago in the first place). This really shouldn’t be that hard.
- Comment on UAE in talks to buy Egypt coastline for $22bn 4 months ago:
Not buying. Investing. The US bought Alaska from Russia. The UAE is investing in Egypt in a large specific area for the benefit of both countries. You will need an Egyptian visa to enter the area, not a UAE visa.

- Comment on Instead of only voting for one candidate we should be able to upvote or downvote each candidate 6 months ago:
Wait until you learn that’s how real countries work! A Parliament gives you proportional representation based on your vote versus the proportion of the populace.
Ranked voting, as you describe, still works better but it is still a winner takes all scenario. Some cities, like NYC, already use it for their local elections because yes it makes sense.
- Comment on Etsy lays off 225 workers after ‘essentially flat’ sales, says CEO | Business 6 months ago:
It’s so stupid how everything just be growth. Flat is fine. 23%+ stock gains, more than fine. Laying off people before the holidays, evil.
- Comment on 'Eyes Everywhere': Congress Is About to Vote to Expand Mass Surveillance of Americans, Experts Warn 6 months ago:
Absolutely. I 100% prefer the Chinese to have all my data. I am a nothing person with no political power so if China wants to surveil me and train datasets with my data, cool. Because the alternative is the US and five eyes having that data and I absolutely do not want that.
Unfortunately it makes you look like the crazy uncle in the tinfoil hat if you try to bring it up. It’s so outlandishly crazy like a Hollywood movie people don’t believe it’s real.
- Comment on 'Eyes Everywhere': Congress Is About to Vote to Expand Mass Surveillance of Americans, Experts Warn 6 months ago:
For anyone that still doesn’t know, this is already a thing for all US made (owned) hardware. Has been for 15 years+. This is expanding it to everything that would be sold on the market. You know phones are hotspots too… That’s right.
You know why the US is so against Huawei? Because they CANT spy on every packet like they can with a Cisco, Juniper, Ruckus, etc switch. And when those start to be installed in scale, it’s a problem for the intelligence collection. This is just a small change to make what’s already there more palatable in stages. So that in another decade when things become declassified fully and more publisized, Americans don’t believe it is an issue.
- Comment on The race to 5G is over — now it’s time to pay the bill | Networks spent years telling us that 5G would change everything. But the flashiest use cases are nowhere to be found — and the race to deplo... 6 months ago:
Yes that’s the talking point Americans like to use as to why their infrastructure is shit. Ok so why does it work in Europe, as a continent? Why does it work in China? Why does it work in Canada? I can be in the Arctic circle not having seen another vehicle for hours on the highway and have full reception. This is in the mountains in the Arctic in a country larger than the US in an area more remote than anywhere that exists in the US.
The reason it doesn’t work in the US is because corporate greed and a population that is ignorant to what it should be. Where’s the outcry over the billions of dollars that the ISPs lined their pockets with for the FTTH rollout and never even remotely got close to delivering, gave up, and walked away…
- Comment on The race to 5G is over — now it’s time to pay the bill | Networks spent years telling us that 5G would change everything. But the flashiest use cases are nowhere to be found — and the race to deplo... 6 months ago:
This is a US problem but Americans don’t travel enough to understand.
In the US I get shitty coverage and frequent tower handoffs to lower bandwidth signals. In a downtown capital city, I generally get 30Mbps to maybe 100Mbps outside on a clear day.
Contrast that with where I usually am, using actual good technology and true 5G, I get fibre-like pings with 1Gbps all the time, even inside buildings. If I’m outside near a tower like in the US, I get 2Gbps nearly symmetrically. Constant excellent signal, no disconnects, no dead zones.
It’s just sad how easily the American populace is duped. Even the article mentions how there were continuous lies and the actual rollout to 5G will take many many years. The rest of the world has already done it. Heck, even Korea has announced 6G consumer installations in the next 5 years. And if you’re by the Samsung Campus with a demo tech, you can use it now!
- Comment on Do really large people need special bathtubs/showers to keep water from getting everywhere? 6 months ago:
Nothing to do with being fat. Some people have zero idea how a shower works. You need to put the liner IN the tub area and the decorative curtain outside the tub. Many people push them both outside the tub. Now all the water that splashes around hits the liner and drains right onto the floor and not into the tub.
The amount of water splashing makes no difference if you’re big or small. Pressurized water hitting you is going to bounce all over. Since you’re taking a shower, that’s the goal.
If I had to guess, the curtain is wrong, he has no idea because nobody has ever told him and the bathroom is terribly non water tight so splashing will go down through the floor. Even tile is not waterproof nor is grout.
It’s why I always specify a waterproof membrane and floor drain but it’s not common in US/Canada yet.
- Comment on You know tipping has gotten out of control when your son says we have to tip Santa with money. 7 months ago:
In America’s hat, common as well. We always set out a chilled glass and a Molson with some Christmas cookies for Santa.
I was genuinely confused when the Americans I later met said milk and cookies… Why milk? There’s no cows or goats in the North pole, Santa is home brewing.
- Comment on Bay Area innovator stops shoplifting, gives shoppers power to open padlocked shelves 7 months ago:
In the before times you would go to a store and it was essentially a warehouse with a desk. You walk in and the dude behind the counter asked what you wanted and you gave him your list. He’d then rummage around the boxes and get you what you needed, you’d pay, and go. You didn’t pick, you just paid. You could even phone in your order and the store would hold for pickup or deliver cash on delivery with options and take back what you didn’t want.
Moving to a self-pick model involved the risk of theft but most of the studies showed it was cheaper to eat some theft than to employ more pickers or have customers leave because of waiting. And that’s what happened. But theft has continued to rise to where now it’s no longer a viable tradeoff.
Of course the recourse is back to company picking. And we now have reverted back to the old way except prepayment is required and some items can be returned… It’s annoying but I see the need.
Having said that, if I’m in a store to self pick, if what I need is locked away I just leave anything else I collected there and walk out. I’m not dealing with that.
- Comment on Offsite Backups with Slow-ish Upload? 7 months ago:
Not just unaffordable, just not available.
That house where I needed to transfer data was in a neighbourhood only had copper phone lines from the 1960’s for DSL and then coax cable. The maximum possible was 400Mbps down and 25Mbps up. Over the years it was increased to 800Mbps down, still 25Mbps down. I paid over $1000 USD a month for that shit internet. Because the only alternative was 4Mbps to 8Mbps upload.
This is a major metro area, 700k people. Starlink was a game changer. Not symmetric, but waaaay better.
There’s only so much bandwidth on the cable line and they’ve spent ages marketing download speeds as the measure. If they go from 400/25 to 400/50, 99.9999% of people wouldn’t understand and wouldn’t pay extra. But make it 425/25 and people will buy. Bigger number more better.
