pen2l··on Therapy as a way of aligning with your subconscious
To be fair, you're a multi-millionaire with the luxury to afford things and freedom to schedule things without stretching thin too much. The typical person in the urban land (at least in my social circle) has trouble finding affordable childcare, which means they just can't go out at that very first step.

I'm not sure how to put this respectfully but I think you guys involved in this conversation here are all just extremely out of touch with real problems people have on a day-to-day basis.

pen2l··on EPFL cancels Stallman's lecture citing “the situation regarding” his persona
My understanding is that he has been misquoted (as OP explained), and anytime he did attempt to make a "defense" for Minsky it was all full of "Yeah technically" in the way that autistic folks tend to process things. The only problematic thing he said, to my knowledge, he recanted and then explained he learned better after engaging with sexual abuse victims to learn more of their experiences. It's hard for me to see autistic people as actual predators, because in my experiences they are almost always the victims who have their intents and words mischaracterized and misconstrued for a dozen and more reasons.
pen2l··on EPFL cancels Stallman's lecture citing “the situation regarding” his persona
We talk about inclusivity here all the time, but what about being inclusive of neuroatypical folks who have quirks that don't come off as being polished and PC in current social code du jour?

This all so so grates on me because it means we are wasting all this time and energy on things that don't matter all the while the real monsters of society go unchecked because with their psychopathic streak they know how to play a convincing PC game on the outside while committing real atrocities.

The thought-leader of the FSF might be socially awkward, but no, people, he is not the great Public Enemy No. 1 some people are making him out to be.

pen2l··on The Missing App Economy (2022)
Nearly everything in that space comes with a sea of confounding factors; biological imperative is fickle thing. I find it akin to gambling, in that folks with impulse control disorder are most susceptible to making rash and often ill-advised decisions.

Point I'm trying make is you can't sensibly extrapolate lessons from there and apply them to a different space. Sadly. Because it is an absolute cashcow and I reckon it probably makes for like a quarter of Stripe's income.

pen2l··on The Wealth Gap in Science: How Your Parents's Income Affects Your Career
Culture in America goes hand-in-hand with socioeconomic status. A substantial portion of desis and Nigerians in America are of the highest economic class back in their respective homes, and they're coming from that culture. If that culture erodes as it can over generations, their social/economic mobility patterns start following that of the rest of Americans'.

In America, today, in streets you can potentially see folks who lived in a time before the civil rights movement. It's an alarming contrast which is being overlooked: the immigrant Africans from moneyed and successful families and the other group couldn't drink from the same fountain as his fellow man, and not be able to send their kids to the good schools

pen2l··on The Effects of Noise on Health (2022)
The average homo sapiens about a thousand generations ago faced greater adversity than what almost any of us has faced, particularly in raw nature where predators roamed. What were the cortisol levels like for that average homo sapiens?

We were always tribal and social animals, so I wonder if the security from communal living played a very important role in moderating stress and building resilience.

pen2l··on MouthPad – In-Mouth Bluetooth Mouse Uses Tongue Sensitive Trackpad
It seems pretty nifty.

I played around with Tobii eye-tracking hardware half a decade ago and was pretty amazed by its precision. I understand now it also has Glasses (vs. the model I tried, a tracker you put below your monitor usually). Marrying eye-tracking glasses with this mouthpad might be a winning combination: eye-tracking being the mouse to navigate in xy-space, and mouthpad for clicks.

Kudos to this group for putting out a finished product though, can't wait to see it used and iterated more out in the field.

pen2l··on Ask HN: Why is TSMC so competitive in semiconductor fabrication?
This might be pedantic nit-picking, but: I think bed leveling/heating, nozzle temperature, choice of material, etc. are parameters that the printer manufacturer should have optimized (and, IME, good ones do). I think the end user's chief responsibility is slicing (infill patterns, layer thickness, etc. as you noted), indeed it is in this sense the end user can be said to be in the same position as Intel/Samsung, not so much the hardware maintenance but knowing the slicing tricks for getting complicated geometry to come out just right.

For example, when you're making a cube, the sharp ends are places where bad things happen. When making sharp movements, the nozzle will tend to leave ugly trails and in other times cause warping. So here you can do a trick to save yourself: mouse-ears (extra material around the important edge, so that the bad artifacts happen instead on additionally-created non-core-geometry). At ground level, you use brims.

pen2l··on Twitter Is Blocking Likes and Retweets that Mention Substack
When I see every new weekly imbroglio he's involved with, I'm reminded of the chat logs that were unveiled in court proceedings: https://jusgu.github.io/elon-musks-texts/

Something very telling was his affectation when talking with Parag. Often with Parag he would use a line like "brb have to go work on rocket science", he wouldn't say any such thing with other people. Point is, the guy is being fake here and all of this hand-waving just betrays his insecurity and fear that he doesn't have a handle on twitter.

pen2l··on Simply explained: How does GPT work?
The more constraints there are (e.g. like your example) the better it should perform. So it disappoints me when copilot, knowing what libraries are available in the IDE it's running in, hallucinates up a method call that doesn't exist.

Separately (and apologies for going on a tangent), where do you think we are in the Gartner cycle?

Around GPT3 time I was expecting for trough of disillusionment to come, particularly when we see the results of it being implemented everywhere but it hasn't really come yet. I'm seeing too many examples of good usage (young folks using it for learning, ESL speakers asking for help and revisions, high-level programmers using it to save themselves additional keystrokes, the list is long).

pen2l··on Django 4.2 Released
Why not just absorb DRF? Which as I understand is the leading choice for many, so I wonder if some effort should be dedicated to reducing fragmentation.
pen2l··on A Reply to Josef Průša
By the way when did Prusa become known for their printers? I was around when Ultimaker 2 was considered the best in a "Just Works" kind of way and Lulzbot was the choice for the more tinkerer/hacker-aligned user.

I stepped away from FDM printers and onto Formlabs' STL printers around when U2 ruled (not exactly a move to greener pastures, they're closed-source all the way), seems like a lot has changed since I left as no-one is even mentioning Ultimaker or Lulzbot. I'm just kinda disappointed and bummed to see Ender of Creality and other Chinese printers enjoying increasing prominence considering their flagrant and persistent GPL violations.

pen2l··on The state of open-source in 3D printing in 2023
Indeed, a variety of open source models have been able to co-exist: There's the sqlite3 type of "it's all open source but you can't contribute to the code"; the conventional community-led copyleft GNU type of open source that gave us Linux; the company-led which creates things like Docker and k8s; and there is dual-licensing (https://en.wikipedia.org/wiki/Multi-licensing).
pen2l··on The state of open-source in 3D printing in 2023
> Hopefully this is an April Fool's joke.

I'm pretty sure it isn't but it is devilishly clever to drop news like this on a date like this.

But as to their decision: It's tough -- obviously we all want to support Reprap movement, Prusa, Ultimaker, etc. and the original innovators in this space of desktop 3d printers, but this is the way things happen, when you've optimized your technique and product the Chinese tend to come and kill you with their high volume low margin approach. Can you really blame them for doing what they're doing? It was probably an existential decision for them.

pen2l··on The Contradictions of Sam Altman
When I was a young person, I used to deride writings like 1984 on the grounds that the scenarios and stories presented to carry the message were too far-fetched.

Reading your comment has set off an epiphany, I think I get it now, there probably exists some higher-up person who is thinking along these lines: we must always be in a state of war, for if we are, the populace will want to be ready and willing to fund the instruments of war. And we always want to be ready for war, because if ever we are not, we lose our capability to win a potential future war. For our very survival we must contribute our efforts to build these instruments of war. War is constant. War is peace.

pen2l··on What is really going on at Amazon Fresh?
Not quite on-topic, but I have to wonder: why go and develop these long-winded solutions when we can come up with obvious better ones? -- order on your phone (which is nice and easy because you can add to your grocery list with a smart home speaker/smartphone list throughout the day) and then it's automatically packaged (in an automated warehouse: https://www.youtube.com/watch?v=ssZ_8cqfBlE ) and delivered?

And for folks who drive to work, have them shipped to their place of work. Places of work make accommodations like have parking for electric cars and cafeterias -- having a place for delivery storage strikes me as an obvious perk that has tremendous benefits for both employers and employees as well as the environment.

pen2l··on More students are turning away from college and toward apprenticeships
Steve Jobs famously wanted to hire people that weren't just good programmers but people with serious and passionate side hobbies and pursuits (music, art, poetry etc.)

Have a broader awareness of things, of other arts, of history, of other crafts must make you better in the area of your core competence in some way I must imagine. For a computer programmer at Apple who is going to be designing a macbook, it's probably better that he have some inkling of what that machine's enduser would be doing with it. Is he going to be making music? Spending a lot of time watching political videos on youtube? Having insight into people, into other crafts will let him make a better machine.

Skills transfer across domains all around, sometimes wholesale and other times in small subtle ways. I was always stunned, for example, in reading Einstein's essays on subjects others than physics. His writings on politics, music, religion etc. reveal a man of tender awareness and care. Would he have gone on to develop the theory of relativity if he had not read works of Immanuel Kant? Leonardo da Vinci, Donald Knuth, Archimedes, the examples are aplenty for accomplished figures who had their hand in many jars.

pen2l··on Men Without Full-Time Jobs Are 33% More Likely to Divorce
Kenji does it when he's playing with his daughter, he polishes her nails and she polishes his -- I think this explanation would fly even in the most uptight and puritanical of the conservative crowd. I do wonder whether he'd bow to the pressure of being more "professional" if he was still making videos under the seriouseats or ATK banner.

Maybe he would, but he is quite an oddball in more ways than one. Both of his parents were Harvard/MIT professors, he is not silent about his political views (he at one point literally forbade anyone with a Trump hat to come in to his restaurant) so we shouldn't extrapolate from this one singular case one way or the other.

pen2l··on No level of alcohol consumption is safe for our health
Fascinating that you keep getting downvoted for stating completely obvious observations. I would have thought your reasonable explanations could convince this supposed 'rational' crowd but apparently not.
pen2l··on Heat pumps are defying Maine’s winters and oil industry pushback
In addition to this, I think we should go back to doing things the hard way, the old-school way: adapt and adjust your lifestyle to temperature changes like our ancestors did. Let the temperature dictate your cooking: do the dishes that require oven use, that require you to have 3 stoves on at the same time (and crucially, avoid these dishes in the summer!).

Go on a bulk in the winter time so that you are more resilient to cold with that extra weight on you (and go on a cut in the summer). Set the temperature a little colder, put on a sweater, do more physical work. This is how the human body has evolved! - to be able to do withstand a little bit of cold, to sometimes be hungry for a long time. Always adjusting your environment for the absolute peak levels of comfort is probably not doing you any good and the heat pump's limitations are not that bad in this regard.

I think letting your life revolve around customs is fun as well as a biological necessity to some degree. If you skip the chance to test it out and let it face a challenge every now and then, you're not doing yourself favors. This elderly gentleman can make it fine alone in Yakutia where temperatures can reach as low as about -100 deg F, you probably can as well: https://www.youtube.com/watch?v=IOltGIaDPlY

pen2l··on Flutter desktop isn’t there yet
On the one hand, ok... sure... on the other:

this just makes me think of the fact that this sort of thing would absolutely never fly at Apple. And I really, really want to say that is shouldn't fly at Google either. They're spending what, 400k on the median developer annually? Have standards, make them have some sense of responsibility and respect for their craft so they don't do this. I mean, like come on, one of the main value propositions for someone considering Flutter as opposed to RN is the fact that it isn't transpiled, there is thus an expectation for widget performance to be basically be similar to that of native code -- well, this is exactly where you proudly and loudly showcase this -- in an announcement video. Widget performance should be absolutely flawless in the presentations.

But all that said, no I don't think that's what's going on here. The things shown right thereafter are stutter free. I think this is a quirk with Flutter. While for mobile/desktop it compiles to native code, for web it does transpile to JS and I think that's perhaps what is being shown there. Though I would think if they wrap it in some sort of wasm the lag wouldn't be perceptible.

It just really grates me that in this day and age this is the reality of UI. If you'd told me 10 years ago that a simple menu shown in a major UI toolkit announcement by the main web player would have these kinds of problems I'd have assumed you were just bad at telling jokes. It also makes me sad because I want Flutter to succeed but seeing these kinds of missteps gives me a pause.

edit: I see now that you're a googler, I'd have phrased it differently if I'd known. Cheers.

pen2l··on Flutter desktop isn’t there yet
Something being highlighted about Flutter is that it ultimately compiles to native code so unlike RN which transpiles to native widgets, its UI animations should technically be buttery smooth.

But in watching the flutter announcement video https://youtu.be/Nu5m1FiS5X4?t=60 (timestamped link) on the screen as menus are opening and the mouse cursor is shown selecting different items, there is... a very perceptible stutter and lag. What is that due to?

pen2l··on Amazon reports its first unprofitable year since 2014
It dawns on me now that perhaps every market and every community is fated to suffer some variation of the Eternal September effect at some certain critical point of capturing majority market share. Every community that matures enough to have argued certain key topics will have decided with confidence on those topics and not kowtowing to the consensus will seem heretical -- the stagnation in some measure spells its doom, Google is thinking how to deal with an increasingly adversarial ground in which many know how to game it with sophisticated SEO thus rendering its main capability a little bit muted, sellers saw that Amazon was a dominant market and sought to exploit the rating system to their advantage, and the end-result is a market saturated with players who were adept at gaming the system.

The interesting flipside observation is that in each of these cases, we see the ground fertile then for a new approach to bud out -- a manifestation of Goodhart's law being consummate. New communities arise in the ashes of old ones, ChatGPT is maybe coming to displace Google in some places, what will take place of Amazon now that its rating system and reputation has tarnished?

pen2l··on Pakistani gov degrades Wikipedia connections due to blasphemy
This is the kind of take that only exists on HN and is obviously wrong flat on its face if thought through for even a little bit. Someone can and does have the right to tell dead baby jokes to a father who has just lost a child but that doesn't mean it's okay that someone should, and indeed in a civilized and social society there are guardrails to prevent that sort of thing: that someone would get rebuked and if they continue being a jerk, that someone would in some manner be punished or rejected from that local community.

We judge the content of what others find offensive all the time, and we even agree that it is subjective, different people of different ages, backgrounds, experiences have different sensibilities, and as social beings we understand and respect this. The internet of course throws a wrench in all of this because it's hard to enforce moderation on a local basis as we do in the real world. But that does not mean that the way we have been living forever goes out the window.

I'm not saying we should do away with free speech, rather just that we have to work through things carefully and slowly. My hope is that after a little bit of debate, a liberal attitude prevails in Pakistan. But to respond with how folks are responding in this thread, of just putting gasoline on the fire, that's not really how progress is made, it is how we further elevate and agitate an already volatile happening -- we should probably not do that.

pen2l··on Pakistani gov degrades Wikipedia connections due to blasphemy
Previously there was a comment that was quite elucidative made by an HN user here: https://news.ycombinator.com/item?id=34304824

In recent years I've come around to viewing the American ideal of absolute "free speech" as not being all that nuanced, particularly because we know know the speed at which viral false and illegitimate claims travel and the slower speed at which reasoned responses to those speech travel.

I think we can all agree that artistic depictions of Mohammad, even if they fall squarely under free speech, are something that are of poor taste because they trigger the sensibilities of a large chunk of people that abide to certain customs and norms. The hope here is that these folks come around to their viewpoints and say "sigh, I don't like what you're doing, but I'm just going to turn away". The debate is front and center, let's see how it evolves.

pen2l··on Japan has changed in important and visible ways
How about Flemish then? It's one of the closest languages to English, so did you have an easier time with that?
pen2l··on Ask HN: Math books that made you significantly better at math?
While it's laudable that you sought those texts and profited from them, I worry about what others might take away from this. When I was young I knew some geniuses who highly spoke of Principia and how it gave them great insights. And the teenager me said, okay cool, I'll have a go!

The problem is that it's in Latin and quite impenetrable.

We have some geniuses here and they would no doubt be able to take away a lot from these texts, but for you normals out there: don't optimize too much, you're quite alright in taking the normal approach of just taking a class at a community college, doing the exercises the teacher assigns, etc.

pen2l··on Migrating our largest mobile app to React Native
The scrolling/transitions animations are jittery in the left in the video, it’s a readily identifiable artifact of RN apps in fact, whereas the native one is incredibly smooth in all refresh transitions and scrolls. I wonder how difficult it is for RN to fix this. Just this one singular improvement in UX would be worth its weight in gold.
pen2l··on Welcome to Comprehensive Rust
Look into Apple silicon - lots of cache, great branch predictions, pointer-chasing prefetchers and more to subside just about all of your compiling worries.
pen2l··on Python 3.11 Delivers
This is baseless conjecture and completely without merit. Guido was intimately involved with this speed-up work. I've disagreed with Guido over things but the things you're saying are just weird. I recommend this interview to get a slightly better glimpse of the guy: https://www.youtube.com/watch?v=-DVyjdw4t9I
