epx··on The future of cryptocurrency is at stake in Ethereum’s switch
Is there any cryptocurrency that is not a PoS?!
epx··on Bluetooth remains an 'unusually painful' technology after two decades
Zigbee failed in a similar way, didn't it? An exceptionally complex protocol (for the intended usage) that left out a major interoperability aspect: the pairing phase. (BT fixed this partially by adding Secure Simple Pairing.)

Wireless protocols are inherently more complex, there are crappy Wi-Fi hardware out there, too.

BT and Zigbee have one additional disavantage over Wi-Fi: they are slow, so they are more heavily affected by packet loss and interference in ISM band. This probably lead to more complex protocols, you cannot do things TCP/IP-simple if you don't have bandwidth to spare in order to retransmit losses.

I’d bet many people here tried to implement Light Cycles AI as one of their first programs
epx··on Orange Pi 800 Keyboard PC – A Raspberry Pi 400 alternative powered by RK3399
And currently a NUC is cheaper than a Raspberry Pi.
epx··on Restarting my career after motherhood
Never understood this employer fixation on unbroken careers.

A career break may happen to anyone by infinite reasons beyond motherhood. Most people have such career-pausing or career-delaying events (health issues, depression, fatherhood, taking care of an elderly relative), most conceal it, motherhood just happens not to be concealable.

And things don't change as fast. Not even in IT. And even if changed, legacy is always there, begging for someone to take care of it instead of going to the newest shiny thing.

People out of the market need some warm-up time? Yes, they do. Even machines need to warm-up, dammit.

What people should understand, is that the economy turns because there are mothers, fathers, and kids. I would be retired at 35 if didn't marry and hadn't a kid. Once upon a time I was buying a car, the saleswoman was worried about her job because of her pregnancy. I said "I am buying a new car because of the kid. No pregnant women, no car sales." (If I were single or divorced, would have a couple vintage cars.)

epx··on Should Freelancers Offer Free Trials?
Have tried this in the deep past, did not work and attracted the worst kind of client
epx··on My Unholy Battle with a Rock64
Expectation: dirt-cheap, power-efficient and reasonably fast SBC computers so you can dedicate one per service (or form a cluster!).

Reality: a RPI 4 costing as much as a whole Intel NUC, but slower, without upgradable RAM, without native ports to mass storage (SATA/M.2), and not as reliable.

Didn't even have to think that far to see that SBC computers are a joke^W^W not there yet. Considered buying a NanoPi or a Raspberry CM + some board to build a router, with at least 2 physical Gigabit ports. Tallying up all components (sbc, case, power supply, heat sink, etc.) made the NUC with 4 gigabit ports look a bargain.

I really wanted to go the !x86 route, but...

epx··on MIT Chose Ethereum’s PoS as Top Technological Breakthrough
Pretty sure the title has a surreptitious message :)
epx··on The data are clear: The boys are not all right
This is because we live in a time of transition. Humans always try get the best of two worlds, XX humans are no different. Men need to learn to speak up.

As I said in the other comment, I am moderately optimistic because some indicators are already moving e.g. you mentioned that more men will go childless. This is already happening.

epx··on Words known better by males than females, and vice versa
I knew some of them but my whole family works/has worked in textiles industry, so biased sample.
epx··on The data are clear: The boys are not all right
But would you sleep better at night if you had a daughter, than if you had a son, because of that?

To my son, I teach that there are no gender roles set in stone. If in doubt, stay single and childless; he has many, many decades to opt out if the Right One shows up.

epx··on The data are clear: The boys are not all right
I have a son, and am moderately optimistic this has peaked already.

As the other commenter said, we see different families in very different mindsets.

I have been personally affected by sexism type B: was expected to work, to be a provider someday, to pay my own way to university, if you want a car you buy it, etc. etc. My sister had the second family car at disposal and the tuition was paid for. There was this undercurrent interpretation of feminism that "women will eventually suffer so they should be pampered when possible".

There were other factors at play: I have a tendency to self-indulgence, my sister does not, so it is prima facie difficult to separate what was proper, individualized upbringing and what was sexism. But sexism was a part; many male friends of the same generation have the same complaint and some could be better off today had they have more support at home.

Then there is this relative of mine, that simply threw his daughters out at 18, since they are supposed to get a wealthy boyfriend and marry rich, so they don't need any further support. BTW they are disowned, too.

This is sexism type A, and make it a big A.

Not necessary to say this strategy did not end well: both are stuck with less-than-optimal partners and careers. We are in 2022 and a nice, wealthy and rational guy won't commit to someone without a career and finances in order.

epx··on How to pick a good monitor for software development
Picked a ultrawide because some IDEs like XCode need a lot of horizontal real estate.

My LG 34" is a bit limited in vertical size, so would buy a 38" or bigger next time. The 1080p resolution is limited but not a dealbreaker for me since I look at it 70cm away (corrective eye surgery = focus locked to infinity).

epx··on U.S. companies are hiring Latin America’s tech talent
It was just an example, a juxtaposition of "respectable" professsions/occupations vs the humble software engineer that now wants to be respected too.

The doctors I know still make many times more than a software engineer with a remote job. And they deserve it.

epx··on U.S. companies are hiring Latin America’s tech talent
Fact is, there are occupations that pay a nice salary in Brazil, even after conversion to US$, even with the current exchange. Brazil is not poor; lots of flashy cars on the streets, upscale bars and restaurants are shock full day after day.

But there is this deeply rooted notion that software engineers are not supposed to make as much a judge, a doctor or a higher-rank bureaucrat of the public sector. The current bewildering is more cultural than anything else.

epx··on McMinn County Bans “Maus”, Pulitzer Prize Winning Holocaust Book
It is natural to certain extent, I did the same at that age. We have a lowpass filter that makes outstanding/outrageous facts (like H) difficult to believe. It takes a while to accept that we humans are actually capable of H, CP and other things.

Another instance of that misleading lowpass filter: "if that happened to group J, the J people must have been doing something to deserve it".

epx··on Ask HN: Are Microsoft development stack and Azure a dead-end career path?
It's pretty much the opposite - have avoided the MS ecosystem for the last 20 years, but I know it is a luxury and it means leaving money on the table.
epx··on How to handle difficult clients
I got depression and slipped for ~3 years because of a difficult client. Since then, I always carry the big stick and use it all the time, in professional and non-professional situations. Let's say I got allergic of BS, and better you hurt than me getting anaphylactic shock.

To get angry when there is a mess-up is not to be difficult. Difficult clients are more like abusive partners. They create the situations that allow them to exert abuse e.g. ask you to drop other clients, then ask for an impossible deadline, then assign side tasks all the time while pretending they don't know this will impact the deadline, then withholding payment, while saying that $1M is just around the corner.

epx··on Sir Clive Sinclair has died
Started with a ZX-81 clone. The factor I liked most was the attention with the manuals, they really cared to teach the basics of programming, even low-level things, to the layman.
epx··on Societies that treat women badly are poorer and less stable
How they treated the ordinary person (man or woman) is the true canary.
epx··on Doctors and pharmacists ramp up calls for Americans to stop using ivermectin
Let's suppose ivermectin has a weak positive effect. I am fine with the possibility. My doctor believed in that, he prescribed it, me and my family took it (my kid would take it anyway for other reasons).

The big problem (in Brazil at least) is, the bozo president and his entourage elected this medicine as a silver bullet, saying that we didn't need vaccines, didn't need any social isolation (let alone lockdowns), etc.

These bozos created a false dichotomy: one thing is to take a chance and swallow some medicine as last-ditch attempt when you have no other known option. They use this reasoning to say nothing else was needed.

epx··on Launch HN: Atmana (YC S21) – An app to help cut down on compulsive porn usage
Any habit taken mostly by men will be demonized.
epx··on Assertiveness is a virtue that anyone can develop with practice
When people see they can't push you, or can't counterargue your point, they play the good manners card "you are being brutally honest".
epx··on Electric aircraft set to take flight by 2026 under new agreements
In the 1990s, the idea of electric RC planes were ridiculed as well. I am moderately optimistic that 1:1 planes will eventually follow, as RC electric cars became "good enough" and 1:1 electric cars are a reality now.
epx··on NodeMCU ESP32-C3 WiFi and BLE IoT boards show up for about $4
Any idea if this board supports BLE Mesh? I've been waiting for an affordable platform to play with Mesh (tried ZigBee but didn't like).
epx··on Fewer young men are in the labor force, more are living at home
"Men are losers, women are misguided."
epx··on Why have cameras and lenses become so expensive?
Some niche markets are irrationally expensive e.g. bicycles.
epx··on Why did bar ends go away from mountain bikes?
I knew I became old when I purchased my last MTB and upgraded it with bar ends :)
epx··on Out of Memory Error – The RAM Shortage of 1988 (2016)
Could be a myth or not, but it was said back in 1993 that a fire in a cresol chemical factory in Japan made DRAM prices to go up, which delayed the adoption of Windows NT.

Semi related: Using some Unix flavor in PCs was a desire for many, but always postponed because it took twice the RAM as Windows. First heard about Linux in 1996 but started to play with it in 1998 when I could afford a separate PC with 64MB of RAM to run it comfortably.

epx··on Volvo and Daimler bet on hydrogen truck boom this decade
+1. Want energy-efficient, electric-based transportation? Electric trains between major routes, they could even be autonomous, or at least don't need a meat engineer on cockpit. Electric small trucks to carry from hubs to final destinations.
