bbarn··on MIT researchers demonstrate rapid liquid metal 3D printing technique
It's been amazing to watch the 3D printing space grow as far as it has. In just the last 10-20 years it's gone from something only dedicated people were able to build and get reasonable results to high precision devices any hobbyist can get their hands on for a few hundred bucks.

I have two resin printers and a PLA printer and I never expected at-home capability to get this far this fast.

But, that's still all effectively plastic we're talking about. I think the problem with metals is still well.. metals. The same types of metallurgy needed for 3D printing have been researched and hit almost a dead end with injection molding (I know there are some metal injection molding systems out there, but it's not hit anywhere near the strength of machined steel yet)

bbarn··on Nine US states are teaming up to accelerate the adoption of heat pumps
Solar with Battery storage is a very useful source for heating energy, even in the coldest climates in CA. Even in the mountains where it drops below freezing at night, most places it's still sunny a lot more than the US average during the day. Most Battery setups I know of target a 4 day stretch of cloud cover for storage capacity, so it is certainly an option.

Where I live at 7000 feet, we have so much sunshine, even in winter, solar is a very viable option. Legislation removing people's ability to recoup the costs is the only reason it's not in every house in the city. The only option left is a much more costly battery setup.

bbarn··on Plastic bag bans work
There are a number of bag that pack down to self enclosed things smaller than a phone. When I lived in Chicago, and rarely drove anywhere, I had two of them in my coat pocket.

Summer time I was always biking anyway, and used my backpack.

bbarn··on Macaroons Escalated Quickly
A macaroon is a mixed up ball of coconut and egg whites. A macaron is the delicious fancy sandwich cookie.
bbarn··on It's so cold, Teslas are struggling to charge in Chicago
Chicago has half the population of the entire country of Norway, in a space 1/50th of the size. It also has extremes on both ends of the temperature spectrum. It's hardly a fair comparison. I spent 20 years in Chicago, the people there are used to and ready for winter extremes.

Teslas have their fair share of issues, but the real problem in Chicago is relatively few people have access to home charging compared to the number that own EV's. It's one reason Teslas are so popular, as every other EV is a pain to charge exclusively with public charging. Reduce their range with cold, increase their charge time with cold, increase the rate of usage with cold (as it's too cold to use bikes and walk for many people) and yes - you're going to run into supply shortages during extremes. To prevent that, you'd need oversupply in the bulk of the year, and the footprint of Chicago and real-estate cost simply doesn't support that.

bbarn··on Everything will be alright in Iceland
Not in Vestmannaeyjar...
bbarn··on Everything will be alright in Iceland
Yeah, that was a standby of one of my coworkers there. She'd often abbreviate it in slack as just "nenni ekki"
bbarn··on Everything will be alright in Iceland
I lived in Iceland for several years recently. One thing you have to keep in mind, is this philosophy is pretty much born out of necessity. Until the US Military built a base in Keflavík (which later became an international airport), the country was quite behind the times. As one friend put it to me "When you were landing on the moon we were getting running water installed"

Iceland was a very poor country for most people other than a few well off in the fishing industry. Today it's still relatively "medium" with few people very wealthy, but also almost no one in destitution. The attitude is that everyone should be able to live a good life, and while it's not truly socialist, it's pretty darn close.

Þetta reddast is used somewhat interchangeably with "I don't feel like dealing with this" and "Some how things will work out even though it doesn't look like it now" and "fuck it". To most people it's kind of an in joke you say when something really sucks.

bbarn··on Cheapest and Most Expensive Appliances to Run Each Year
The only thing I found kind of interesting was comparing a single incandescent bulb to a 43" LED TV. Makes me wonder how much the old tube TVs used.
bbarn··on Volkswagen Will Bring Back Physical Buttons in New Cars
The 12V loss is something that really sunk in working on older cars. You wouldn't think a cable that read 0 on the ohmeter could still not sufficiently carry power, but it happens. Starter systems especially - My old van I remember wouldn't start once and all I had to do was clean the terminals on the battery with a wire brush.
bbarn··on Figma and Adobe abandon proposed merger
It's not completely implausible what you're getting at is right, even if your numbers don't quite make sense.

Consider also the fact - news of this merger was almost universally received poorly by Figma users. The internet was awash with "open source equivalents" - "You don't need Figma" articles, etc.

bbarn··on More product, fewer product managers
As a developer, and a development manager, the best product managers I've worked with rarely got involved in the "how". Sure, they may generate epic-level tickets in your back log, but lower than that, they trust you and the project people to get things done.

Problem is, the org needs to support that, and in most companies, the work that gets the most attention isn't visionary or growth focused, it's whatever is making the loudest noise. Often that is in direct conflict with a product owner/manager's desires.

bbarn··on Maybe getting rid of your QA team was bad
This is a great model, until those people so familiar with the business needs end up.. doing business things instead. It's really hard to keep people like that in a QA role once the business recognizes their value. Kind of the same problem with QA automation people - once they become really good at test automation, they are effectively software developers, and want to go there.
bbarn··on Anti-aging drug for dogs moves closer to gaining FDA approval
> high quality, 95+% meat food (dry and wet, the cat picks whenever she’s hungry)

I think this right here is the smartest thing you can do. Cats are obligate carnivores, and some of the crap in the stores is just fillers they crap out anyway. Same with dog food - they design it to make poop more solid and easier to deal with.

bbarn··on Tesla Cybertruck Pricing and Specs
Also Parking.
bbarn··on My toddler loves planes, so I built her a radar
Great idea. Simple but effective, I'm up on a mountain with weird military traffic here and there, in addition to commercial stuff, so I'll play with this when I am driving around for sure.
bbarn··on Sopwith – a classic bi-plane shoot 'em up from 1984 in the browser
Wow, that's wild. I feel like you could sue for damages now, but I can't be sure if that was possible then.
bbarn··on Should I replace my 56k modem with a 28.8K Modem? (2001)
Man, this brings back memories - but I'm a little surprised 2001 is appended to the title. In the mid-90's I got my first 56K modem and expected a world of faster connections only to realize every BBS I was on didn't support it anyway.

By 2001 I think I had cable service, and most people in my area could get it (suburb of Chicago at the time)

bbarn··on Almost no one pays a 6% real-estate commission except Americans
I have gotten a lot of value from the two I've used as a buyer, and also the one I used as a seller.

On the buyer side, once we'd toured a few houses and they understood better what we wanted, the number of "No, not a chance" houses dropped to almost zero. Also, when we were just "tire-kicking" and said we had no intent to buy for a year or more, our realtor flat out told us she enjoys seeing new houses and even if we aren't ready it's good leg-work and research for her to do for other clients anyway. Once we found one she was excellent at getting us to the right people for financing, inspections, etc. - in a very small local market. She was also incredibly helpful when we were trying to find a temporary rental from across the ocean remotely, which is what led us to ask her to help find a house to buy eventually.

On the seller side, we left the country, and my realtor sold our house at an amount that covered his commission and then some with almost no effort from us at all. He had the place cleaned, staged, and photographed as part of his fee, and sold it in a day.

Yes, I'm sure like any occupation there are people bad at their job and just collecting cash for doing damn near nothing, but if you find a good one on either side, they can add a lot. Look for referrals from people who've had good experiences, and don't just pick a name from the phone book.

bbarn··on Mom and pop shops are cutting software spending, creating jitters on Wall Street
One of my best friends literally runs a donut shop down the street, and he's trying to break into software development.

At some point you run out of jobs to replace, while just making your product less appealing. The entire world can't be employed by tech, and the answer isn't cut out workers - it's stop making things expensive. If technology drives efficiency, why do prices constantly rise instead of fall?
bbarn··on Mom and pop shops are cutting software spending, creating jitters on Wall Street
The thing I miss the most about Iceland (and Europe) having returned to the US is how utterly easy it was to buy anything, at the price advertised, and use a phone/watch/card as the payment method without the checkout person being phased by it.

I utterly despite tipping culture. It's gotten even worse since I returned. Now not only are tips expected we have crap like service fees and "cost of living adjustments" as line items on checks that are trying to put even more responsibility on the customer to pay for employee benefits.

Until a different human prepares it and missing the line on the order ticket...

I suspect you might be in the minority, unless the staff is outright atrocious. I love interacting with other humans. Working remote so much face to face interactions are a positive for me. I don't want to spend my entire day pushing and clicking buttons then my "break" from that is pushing and clicking different buttons.
bbarn··on A Lot of Damage in Grindavík
While anything's possible, the trend of recent eruptions in the Reykjanes peninsula have been more of the slow trickling small kind. They have also been relatively off the beaten path, so it's hard to compare ground shifting in the previous places since you likely wouldn't notice it after the fact like you will with pavement and buildings.
bbarn··on A Lot of Damage in Grindavík
I can tell you for sure there are no such heated roads in Grindavík. The one in Reykjavík is on a street that cars can drive down, but in practice don't very often. Large plows would struggle there and the pushed off snow would clog the walking areas in a very popular tourism location.
bbarn··on Swedish unions strike: Blocks mail and package deliveries for Tesla
Iceland also has very bizarre "union" structures that more resemble professional associations than unions in other countries. When I worked at a software company in Kópavogur, on my team of 7 there were at least 4 different unions represented.
bbarn··on We have used too many levels of abstractions
I think you may be confusing what you see with the cause.

For example: You and I HAD to be willing to go through that, and we were fascinated by it. There are still plenty of great FE and BE young devs who see something and instantly ask "How does this work" and keep going down. The difference is, most people in employment don't HAVE to do this like all people in our early career did. If those shortcuts to getting paid existed in our early careers, many of us would have taken the money and not cared. It's not an experience or a "You had to be there" thing, it's simple curiosity and motivation that sets people apart in this regard.

bbarn··on Homebrew to deprecate and add caveat for HashiCorp
I don't have too much issue because when it's bad, it's usually because they've failed pretty hard on tech screens for questions that have absolute answers. I have on one occasion had to pull up my IDE and run code and prove my questions to an argumentative candidate, but generally people appreciate the explanations when they are wrong and tell me they've learned something.
bbarn··on Homebrew to deprecate and add caveat for HashiCorp
Not at HashiCorp, but I try to respect applicants' time in interviews, and my overall process is less than 3 hours total for interviewing, across 4 people (all of which are self-scheduled). That said, when you have hundreds or thousands of applicants, people inevitably fall through the cracks unless you have an internal recruiting team entirely focused on maintaining that experience.

Interviewing sucks for everyone on either side, and efforts to improve candidate experience on my end have often been met with resistance in the company. One thing I've done is try to be as clear as possible at the end of interviews where someone stands. If it doesn't go well, I try to relate what didn't go well and how it applies to the position we're hiring for. If it goes well, my interviewers and I try to send out invites for the candidate to schedule the next interview within 10 minutes of completion, and I tell them that during the call.

So many companies are so risk-averse though, that they act like interviews are a poker game. I've generally had nothing but positives with my approach, and yes, someone may sue us at some point for being blunt and upfront, but my experience so far is people appreciate honest feedback if you deliver it kindly on the spot.
