intpx··on Ask HN: How did an adult ADHD diagnosis help you?
you may want to talk to your doctor about other options for medications. I'm not going to name names but there are much slower, longer acting meds that are precursor drugs that you metabolize into the drug, for example.
intpx··on What Really Happened When Google Ousted Timnit Gebru
What better way to silence criticism than to welcome it inside the walls, give it fancy titles and high salaries and absolutely no power.

I disagree that AI Ethics is a bullshit field-- but its one that belongs, has to belong, on the outside looking in. Its an academic field and a watchdog field. Its a subset of Ethics, not of AI. If Google were really concerned about AI ethics they would have set up an external entity with a consortium of other industry partners, seeded them with an endowment large enough to have some measure of intellectual freedom, put them under the auspices of an external parent organization with a long and positive reputation and severed all ties with them. They wanted the optics of ethics, the new car smell-- but they didnt wan't to breech the membrane of plausible deniability when someone internal pointed out that their golden geese were causing some problems.

intpx··on Google Docs will now use canvas based rendering
teach markdown in schools. who needs word processors anyway? need something fancier than headings, lists, block-quotes etc? learn LaTeX. Text rendering can be fantastic in the browser. I'm half joking, but I think the world would be a better place if folks had fewer, more precise ways of making words look the way they want
intpx··on Why are modern 50mm lenses so damned complicated?
> photography is artistic & creative in nature.

This is a pretty broad generalization. There is plenty of photography that is nothing but technical. Also, the technical side of photography is what drives the innovation to enable the creative side. Do hobbyist landscape and portrait photographers need to be pouring over test data like this or even benefit in appreciable ways from these advances? Not likely. But the R&D that is done in optics begins with some of the most technical fields and trickles down.

intpx··on Spotify is killing the open podcast ecosystem (2020)
This post is essentially a funding pitch for Spotify. I talks a lot about they are going to try and kill the open podcast ecosystem but no evidence that they are making any progress. The podcast ecosystem is very different from other media markets-- it started open, it grew up open, and people are actually willing to directly pay content producers either for bonus content, to avoid ad reads, or just to keep the train chugging along. I immediately unsub from any podcast where there is some jarring dynamic ad insertion. I've watch all of the once great Gimlet podcasts wither, and some die since their acquisition.

Yea there is a market for the low-est common denominator stuff like low-brow true crime stuff and the joe rogans, but I don't see those as competition, either for sponsors or ears to the healthy, robust, mature open podcast ecosystem.

How is this not a blatant violation of FERPA?
intpx··on Apple now lets you transfer your iCloud Photos to Google Photos
in the meantime, https://github.com/icloud-photos-downloader/icloud_photos_do... has been pretty reliable for me.
intpx··on Building an E-Ink Laptop
If slow is what you are looking for, there has finally been some movement on building controllers for bog-standard e-ink panels like you find in kindles. Refresh rate is far below the 75hz in this project, but the price is too. my 10 second search didn't find the project notes I had in mind but I'm pretty sure this is the same end result: https://www.waveshare.com/7.8inch-hdmi-e-paper.htm
intpx··on The nihilism of r/wallstreetbets
if i give you a dollar and you give it back to me 7 billion times, 14 billion in volume occurred with $1. some percentage of this is tomfoolery that triggers cascades in the HFT space and create a lot of volume without much sound.
intpx··on Ask HN: Is anyone using ArchLinux for server production environments?
Hardly. The centos streams definition of rolling release bears no resemblance to arch’s definition. Centos streams will effectively be a point release ahead of RHEL and substantially behind on security releases.
intpx··on CentOS Linux is dead–and Red Hat says Stream is “not a replacement”
I'd recommend anybody truly curious about this check out ep383 of the Linux Unplugged podcast. Its the only serious analysis of the shift, with people in the know, that I have seen. No, its not all roses and sunshine but the 'community' response has been so universally full of FUD and dumb assumptions. RedHat bought the CentOS project and they did it in the service of RHEL. Its kind of amazing that something like this <<hasn't>> happened already over the last 6 years
intpx··on An open source portable terminal for every dev
its an inherently hackable platform
intpx··on Would you be willing to fund a Linux port to Apple Silicon?
what on earth are you talking about? time is made up of seconds, minutes, hours... etc. reducing wait time increases productivity. The larger and more complex a project becomes, the more these delays compound. A sub $1k laptop with the the computational power of a workstation that costs many times that, and isn't portable is an absolute game changer in many areas. If I worked for National Geographic or the New York times as a photographer and needed to preprocess several thousand images or 4/8k footage from the field so I could make print deadlines, 3 hours vs overnight means everthing.And more importantly, the amount of power consumed by the cycles is far from trivial. An x86 mobile workstation can't even complete certain render tasks on a single charge that the macbook air can do on less than a quarter of a battery charge.

As for compile times, believe it or not, lots of projects are written in something other than highly optimized C code and compile time is a real pain point. You don't always have a choice of what language or dependencies you work with.

Just because there is an alternative way to do something, or a way that takes longer doesn't mean its viable. Performance improvements matter, a lot. Power consumption improvements matter, a lot.

intpx··on AlphaFold: a solution to a 50-year-old grand challenge in biology
exactly. Even an incomplete map with somewhat limited resolution makes navigation a hell of a lot easier than flying blind. This effectively is a data reduction solution-- if you have a fuzzy shape of the thing you are trying to model, and you learn the mechanics better with each thing you model, your ability to quickly and accurately reach a goal improves

intpx··on Raspberry Pi Webcam
the TLDR is: better, but you lose important features like autofocus.
intpx··on Oxford University breakthrough on global COVID-19 vaccine
no real idea, but my guess is that its likely true that mRNA fragment production is cheaper, but inactivated vector manufacturing is already scaled up and out globally and mRNA is not-- existing labs around the world can maybe be more easily equipped to scale up production?
intpx··on Apple’s M1 silicon is all about platform control
So end-of-life releases that have been replaced with newer builds? Any application that doesn't survive the progression of technology doesn't deserve to-- software requires maintenance. We expect hardware to get bigger/faster/stronger but are unwilling to hold software to the same standard?

I am wracking my brain but cannot think of a single application that I ran on previous epochs of hardware (whether it be 32bit, PowerPC, Itanium, or anything else) that I am now missing out on.FOSS has really mitigated this a ton too because if there was a good idea from a defunct codebase, inevitably a project would spring up to fill that void.

Professionally, legacy software is the bane of my existence because I am expected to move heaven and earth to make crappy, long outdated and inherently insecure proprietary enterprise apps work on modern networks with modern operating systems and modern security requirements. Let it all burn.

intpx··on IoT Unravelled Part 1: It's a Mess but Then There's Home Assistant
man, i feel completely the opposite. Once I realized there was a world outside of the IoT 'products' with proprietary ecosystems and that I could build my own, I found this whole world that took me back in time to the early days were I was working much closer to the hardware. Writing code in C, soldering i2c peripherals to microcontrolers, etc. And at the same time its given me real world use-cases to learn the new hotness tech like docker, mqtt, and some industrial stuff like node-red.
intpx··on Nvidia Announces A100 80GB GPU for AI
wow... uh science? for one.Smaller outfits and research groups that want to do rapidly iterate through modeling and simulation but don't have a datacenter. the A100 is about 11 times more performant than a p100 in HPC benchmarks. You can get a dgx station a100 with 4 A100s in it and run it on mains power and have the equivalent of 44 p100s under your desk (for these applications).
intpx··on Introducing the next generation of Mac
Not all RAM is created equally. Better memory management means less RAM can be better than more RAM. Pair that with superfast flash storage for SWAP and you might not even be able to tell the difference between 16 and 32.

Besides, this release cycle is 100% optimized for an impressive speed boost, tempered by a need for a more impressive battery life.

The proof will be in the pudding.Time will tell.

intpx··on A novel polymer should make 3D printing more effective
newer stepper drivers have dramatically reduced noise. There have also been some pretty dramatic speed improvements made with newer motion control systems like CoreXY and Delta.

its still several orders of magnitude faster and cheaper than sending a schematic out to a traditional manufacturing prototyping shop, at least for parts that are appropriate for this particular method of manufacturing

intpx··on Adults with ADHD show decreased function in brain dopamine reward pathway (2010)
I'm on a very low dose of lisdexamfetamine and i freaking haaaaate missing a dose. As I understand it, it is a precursor of dextroamphetamine and your body converts it into it slowly through a metabolic-like process-- so pretty similar to XR but less of a saw-tooth curve throughout the day and more of a single sine curve. I wouldn't call it a nightmare, but it sometimes feels like one. It is really a miracle drug for me in terms of letting me let myself comply to external demands on my attention and order my life.
intpx··on Moved a server from one building to another with zero downtime
probably because proper architecture (clustering, HA etc) and planning would have never made this an issue. This is still an extremely risky operation, hot swapping power and switching interfaces on the fly all while sitting on a cart in a corridor. In any disruptive work there is never a guarantee of no downtime for affected assets. I know the OP came in as a consultant, but If I was the MSP tech, I would have demanded a paper trail a mile long to cover my ass if this went sideways and If i was the account manager for the client, I would have refused the work. Its not good business to agree to do work where you know there is a better than good chance there will be an outage and your client is saying they wont pay if there is an outage. Even agreeing to it puts you in a bad spot for future work. I guess as an outside consultant, bewilderment is a better reaction than ranting, but this is the kind of shit that drives ops folks crazy
intpx··on macOS 11 Virtualization Framework to Run Linux in a VM
I'd argue that very little is actually known about the A12Z hardware implementation details because there are not many out there and they are largely in the hands of folks trying to build their commercial software as fast as they can. I'd wager the MacOS 11 build for these developer platforms is largely focused on just making sure Xcode runs and not extensibility in the system software
intpx··on macOS 11 Virtualization Framework to Run Linux in a VM
pardon my ignorance, but how is QEMU not virtualization? There have been MacOS builds of KVM/QEMU for a couple of years now and I distinctly remember seeing that it had either been added or was being added to the base OS (google-fu is failing me because of so many results about the reverse-- running MacOS under KVM/QEMU).
