intpx··on Miniature 3456 LED Cube
Projects like these are not about the destination, man. They’re about the journey. My guess is that more than anything this was an exercise in learning the processes of soldering small, tightly packed smd components.
intpx··on Can you drill into a supervolcano to relieve pressure? (2016)
This is a very clear distillation of the absolute lack of imagination that is endemic across the National Parks Service. It is this mindset that stagnating progress in the National Parks. 105 years and there have been no major developments in Parks technologies. No waterfalls running in reverse, no water-skiing bison, no Grander Canyon. /s

intpx··on Bouncing a LoRa message off the moon
Wasn't it designed for sending sensor data from oil wells spread out over vast swaths of land or something? I've always though of it as shortwave/vhf for packets
intpx··on Nanos: A kernel designed to run only one application in virtualized environment
that's nice. It doesn't change the fact that its incredibly bad practice to ever run a piped curl, thus its incredibly irresponsible to make it the top of page delivery mechanism for your shiny new project. Its even more irresponsible to put that silly little shell script behind a url shortener. That's like, two major security, and just plain old fashioned hygiene violations and I haven't even moved past the first line.

Things like this shouldn't be 'easy'. they should be well-documented, sane and safe. This is certainly an interesting and novel approach to tackle some of the absolute mess Docker has made of the world, but at the end of the day, if a system is compromised, its compromised, whether that be the docker user or the kvm/hvf group members.

Isn't the whole drive behind hacking to make something do things other than it was intended to do?
intpx··on I built a $5k Raspberry Pi server (yes, it's ridiculous)
yea, i totally agree with everything you are saying except that making a silly face in a thumbnail does not carry the same ethical weight (or really any at all) as unbreakable DRM or malicious pop-ups or uncancellable subscriptions. So i guess, in conclusion, i don't agree with you at all and i think your argument is complete horseshit. cheers!

That's an awfully short hill to die on.

Youtube is gamified. Jeff doesn't play the game, he doesn't get the views. If he doesn't get the views, he doesn't get the sponsorships. If he doesn't get the sponsorships, he goes back to being a just another devops engineer who doesn't make the thing no one else will ever make.

I get it, the face is the worst. But until youtube fixes its algorithm (i dunno, to de-prioritize videos with 'the face') the Jeff's have to do the face to get the views to get the algorithmic advantage to get the views to get the sponsors to make the making worth the making.

yea, or product reviews (especially for more esoteric things). you can immediately tell if its real or a bot generated slideshow with a TTS of amazon reviews
intpx··on Suppose I Wanted to Kill a Lot of Pilots (2020)
I traded the walk in closet for my bed and desk space in my freshman quad. not having windows was a small price to pay for not having to share the air with 3 other freakin weirdos.One of them could only sleep with a desk lamp on, which didnt bother one of the others who was 100% nocturnal and went into an absolute rage if you woke him up before about 6pm. The third pretty much lived in another room
intpx··on High-fidelity remote communication
Have you tried a supercardioid dynamic mic with a pre-amp (like the sm7 in the post)? These mics have a fairly tight pickup pattern, especially with higher frequencies and with a pre-amp you can adjust the gain so that it really only picks up when you are very nearly touching it. Also, deadening your environment goes a looooonnnng way to cutting down on background pickup noise. rugs, acoustic panels, divider curtains etc.

intpx··on 14-inch MacBook Pro review: A Mac Pro in your backpack
I'd say that given no teardowns have yet been released, its also true that we know there isn't a specific reason for the brick look. They crammed a lot of battery in there, big, slow, quiet fans, six speakers, and the SoC is something like 4x larger than the base M1.
intpx··on Scientists discover a highly potent antibody against SARS-CoV-2
An ounce of prevention is worth a pound of cure Also, since vaccines reduce death to almost 0, and a 'cure' on top of that reduces death by 80-90% (as you claim), if everyone is vaccinated that can be, and there is a treatment, there is no more disease, but thousands are still dying every day. So we need the vaccine mandates.

Additionally, death is only one of many of the devastating outcomes of Covid. In many cases there are profound and longterm effects. So we need the goddamn vaccine mandates.

intpx··on A USB Fan Controller that now works under Linux
Still overkill. A 555IC, a variable resistor, a thermistor and a few passives is all you need. You could get the BOM for the whole #! down to under a buck.

intpx··on A different kind of keyboard
Holy Baader-Meinhof Batman! Just yesterday I had the idea for a phonecase that had a few buttons on the back-- nothing so specific as a chordic keyboard, more for things like a camera shutter button and some other macros. I even started roughing out a schematic. The FaunchPad looks sort of ill suited for the task because its wired but there are some good BLE SoCs out there now that can sip power.
intpx··on The Linux Experiments YouTube channel has been terminated
the only thing sad is that its the reality of the situation. Tor started off with some pretty pie in the sky ideals and now over half of its active use is for illegal activity. Tech censorship doesn't even register on the scales of stuff that is de-platformed from social networking platforms.
intpx··on The Polar Bear – Open-Source, Multipurpose CNC Machine with a Rotary Axis
So many critical comments, with albeit legitimate critiques, that are missing the point. This is an open source hobby project that is designed to be built with a 3d printer and a few inexpensive off the shelf parts. I have yet to see another rotary table based cnc project like this. does it have some inherent design compromises and short comings? yes, but this is a starting point. The initial reprap project was (an ancestor of this project, no doubt) was also very flawed. This is the starting point of a pretty novel take on desktop cnc and if it gains some traction, will also evolve and iteratively improve.
intpx··on Liquid cooling next-gen servers getting hands-on
RGB-life liquidcooling != Data Center liquid cooling

They have precision dry break quick connects. They use crazy jacketed hoses with PTFE liners and copolymer sheating, sometimes with reinforcment layers. The coolant is pumping through at an operating pressure of 10bar @ 200C. These applications exceed the limits of potable water and hydronic heating systems

intpx··on USB-C Cable Colour Codes
i mean, the real solution is to only buy good, compliant, backwards compatible cables and largely standardize with the feature set your most demanding high-use device requires, but that could put you at $30+ USD or more per cable.

I tend to buy Anker cables and color code them by capabilities. though to be honest, i didn't even realize USB C 3.2 had two generations-- i was pretty much just breaking it down by: white/silver 100W PD, red for 18W, and black for unknown came-with-a-thing.

btw, its about to get better and worse https://www.theverge.com/circuitbreaker/2021/5/25/22453936/u...

intpx··on A PTA Purge of Asians
except that placement in magnet schools and similar programs has been proven to have nothing to do with student intelligence or ability-- its parental lobbying and teacher bias. What is suspiciously absent from this opinion piece, is what exactly the changes are to the TJ admissions process. Previously, acceptance was blind to what school a student was applying *from*, so 1/2 or more of the students came from 5/25 middle schools. The new model takes geography into account. Additionally, only 2-3% of TJ students were in the FARMS program, in a school system where over 30% of the total population is in FARMS. Tell me how parents are equipped to navigate the insanity of trying to get their kids into a magnet program when they are at less than 130% of the poverty line? The starting line for admission for kids in Fairfax county is widely variable and nearly all of the factors that influence that are out of their control. The changes to the admissions process aren't about race-- they are about class and social status. These Coalition for TJ nimbys and the goons like McGurn who perpetuate these class divisions are twisting the facts to fit their narrative and victim complex.

his livestreams have taught me more about board design than anything else. also, this is an incredibly well documented board, as he livestreamed much of it and opensourced everything
intpx··on Verizon wasn't responding, so an angry customer found a brilliant solution
I'll have to try this-- I live in a place with terrible cell data service so when my fios went out this weekend and I tried calling, they kept telling me to use the app. how the hell are you supposed to use the thing that's broken to communicate that the thing is broken?
intpx··on The Reason for Windows 11
and if it, you know, actually mitigated the most common threat vectors (that all run in userland and microsoft does next to nothing to effectively stop) like ransomware.
intpx··on The Reason for Windows 11
to my mind, what sucks about Microsoft's 'hardware upgrade' is that it will drive the entire PC industry to build hardware that has a proprietary Microsoft lock on it. Secure Boot is not an open standard, it is a Microsoft owned and controlled lock. I have already run into enterprise grade machines that forced secure boot, making them useless in our organization. I haven't found any info on the 11 logo certification, but for 8.1 they required it and required that it not be able to be turned off. I'm all for increased security, but I'm also for general purpose computing. If I buy a machine with a particular instruction set, I should be able to some way execute any code I want on that computer. Same goes for Apple, though to be fair, it is possible to execute any code I want on an M1 Mac, I would just have to essentially reverse engineer the hell out of everything. And yes Apple should provide at least a basic level of documentation for targeting their hardware and they do not. I am a slightly more charitable to their position because they brought brand new capability to market-- Microsoft is just corralling the vendors into tacking their propriety firmware lock onto the same technology stack. If this was a chip manufacturer initiative, say AMD wants to bring new capabilities and security by only accepting signed OS builds I would be far more receptive to that position, so long as there was a reasonable, accessible and equitable path for getting your builds signed.
intpx··on Ask HN: How did an adult ADHD diagnosis help you?
ADHD is a disease/difference of executive function-- how your internal world interfaces with your external world. It totally makes sense that you had a tough go of it when you experienced major life changes.
