> As with so many aspects of their society, it seemed to depend on subsuming the needs of the individual to the needs of the community.

It gets kind of exasperating when you see this kind of writing about your own country. Perhaps from an American perspective, it seems like some sort of socialist heaven here, but it really isn't.

Our healthcare system is teetering, our elderly care system has already fallen. We are still laying down more asphalt 'because it will solve traffic jams'. Moreover, we've been eating away at some of our social safety net. Our prisons stated goal went from rehabilitation to retribution, and the police have more issues with 'confused people' which is a polite way to say people with a mental illness.

One of the bigger issues is that of affordable housing. A recent report stated that 25% of renters forgo normal expenses to make rent. Moreover in the bigger cities we see foreign money guying real estate as investments just like in London or Seattle. Which brings me to the hypotheekrenteaftrek (tax rebate on mortgage interest). Which was pitched as helping the middle class afford housing, but turned into a massive tax credit for the rich. Now, we know this thing is pushing up a housing bubble, but we are afraid to do too much with the rebate for fear of popping that bubble.

Not to mention the recent political push to abolish the dividend tax 'because it would help all business', not to entice Unilever and Shell to fully incorporate here. Only for the plan to be rescinded when it turned out Unilever wasn't gonna move here after all.

And despite the large number of bicycles, we still have a shit-ton of cars. Whilst it is not uncommon for people to cycle to work, taking the car is still more common. And not having a car at all is a pretty rare thing. At the same time, the increase in e-bikes is causing dangerous situations, and a marked uptick in broken bones, especially among the elderly.

My point being, the Netherlands aren't some perfect place to emulate, even though we have bike-lanes and drivers and cyclists here are used to seeing other cyclists on the road.
Thank you for reading my rant.

No, I was planning to and then every 2 bit Lego trader and bricklink contacted me to try to go commercial with it. That's not how I envision this and so I decided to keep it inside for now. A ton of work went into labeling the dataset (many 10's of thousands of images), and there is no way I will let the likes of Bricklink and overpriced parts sellers use it to corner the market.

This is very much a mom-and-pop market, and there are countless people out there that augment their pensions by sorting Lego by hand and re-selling it.

Releasing this would put them out of business overnight, or, they'd have a grace period as long as someone does not put together industrial mechanics for it and then it is 'game over'.

The true image is that

(c) even if it was true, 65-year olds forced to learn to code and desperate for work, is not a positive thing, it's a societal failure
Nothing wrong, but also nothing worth discussing. It doesn’t qualify as a good research or an opinion of a subject matter expert - just few banalities in a popular genre of provokative tech blog post.
One reason to care is when designing applications that work well for all users. In particular, I've noticed that in recent years there's been a trend of colourizing CLI tools, often assuming a black/dark background.

So now your CLI tools emits yellow text on my white background, and the first thing I have to do is figure out how to fix or turn off these darn colours. In some tools it's non-trivial to do so.

I use a white background (just the xterm defaults, never bothered changing it).

Try Cycling in the Netherlands at 30 km/h near pedestrians (even when on a bike-lane) and you will get no sympathy for going over the handlebars.
Heck, cycling at 30 km/h on any kind of bike lane will be disruptive to other cyclists. The norm here is somewhere between 15 and 20. Anything over 20 is seen as putting in effort.

Actually, it's more of a conformist than collectivist society. The misconception comes from studies done in China regarding collectivism vs individualism in the 80s and 90s, that were 'Margaret Mead'ed: sitting people down in a formal classroom to take a test being administered by scientists with government permission didn't have the same effect in China and the western countries it was being compared to.

Collectivism is commonly seen as a valuable presentation in conformism-driven social environments.

In an unclear situation (i.e. any busy city), doing 30 km/h is way too fast. The sibling post talks about 25 mph = 40 km/h(!), that's racing speed, pretty dangerous if there is other traffic around.

There's a difference between the cycling the Dutch do at 18-20 km/h -- maybe 25 km/h on a dedicated cycle path with no chance of interaction with other traffic -- and race-cycling at 30+ km/h, which is in no way appropriate in a city with pedestrians and cars. I saw it in London too: very busy streets, and the cyclists are in full racing gear on racing bikes where they're hunched over instead of upright (bad for overview of traffic situations), doing 25-30 km/h, that's asking for trouble and it also gives cyclists a bad name.

It also explains why people complain about getting to work sweaty -- they're going way too fast! If you relax and do 18 km/h, it will take only a little bit longer but you won't be soaked when you arrive.

You know I was just saying to someone the other day, the VR headset has NOTHING to do with it, it's just a matter of putting you on in a scene, it's a means to an end.

Originally I explored the phrase "experience transfer" because I was taking real calls and replicating them, as much as I could, into VR, then have someone else go through it, it was as if I transferred experience from one person to another.... I wrote an article titled, "How many years does it take me to have 10 years experience" exploring the possibility of this. Ultimately, First Responders just want to work out or hone these critical thinking skills, as easily as they can get good at practicing a rope knot.

How does this sound: "Uses VR to allow First Responders to gain experience faster."

This video is awesome, thank you! I'll probably need to watch it twice.

This strikes me as an odd statement. Some individuals may go their whole lives without taking antibiotics, but that tells us nothing of interest about antibiotics.

There is a real question about whether it's better to wear a helmet, though. A bike helmet can of course save your brain in case of an impact (which studies have confirmed), but studies have found that drivers leave less distance when they see a cyclist wearing a helmet [0].

Yeah, being a responsible adult with a good life outlook and interesting work is honestly pretty fun.

Having fun has diminishing returns. At some point, like with any addictive behavior, it becomes a matter of habit. Tons of people are in this rut and don't realize.

Ask HN: Promoted to Management, but Have Doubts
Recently promoted from lead engineer to a high level management role (below the executive team) in a small company (~100 people), but I'm not enjoying it too much. I feel I'm wasting my time with operational and solving small issues around unblocking the team, while my technical colleagues are doing interesting work. I have the feeling that I'm falling behind in technical skills and, if I decide to go back, the time I spend in management might end up biting me.

I took the role because "it made sense" from career progression point of view, but now I'm struck with doubts that I just became an average manager from a relatively good developer. In all honesty I was also after the salary increase, but that didn't really materialize as I hoped. In my current company I have a decent pay, but still way below what I could earn elsewhere. The thought of moving somewhere else in a technical role and for a higher pay pops up more and more in my head. On the other side, the company's doing great, growing, sales are going up; it's a good time to be here, which add to my overall feeling of confusion.

I guess the questions that I have for you HN are:

1. how much time spent in management land is too much and has a negative effect on your career as an IC?

2. what would you do in my shoes?

I've been mentally stuck in this situation for a while now. It's taking up all of my mental and emotional energy, any thoughts are welcome.
Having worked there only a few years back, I can guarantee there was still a very large amount of mainframe activity - all the change management at the time was still done on an IBM mainframe.

How are you measuring that, exactly? Here is a reasonably quantitative analysis:

I don't know how many Brits have reached their conclusions about the EU "all by themselves", without basing their information at all on what the media and UK politicians have told them.
You use it in an environment where you need an extreme level of data integrity and availability. Think banks, airports, government, etc.

Due to io offloading to co-processors and a whole range of supporting cpu types you can set up a system which can handle thousands of transaction per second. Most of the application that are used on mainframe's are databases or message que's

Recently there is an increased interest in running Linux on mainframe's something which can be done since early 2000 you get the benefits of high available and secure hardware and the relative ease of Management of Linux. Another benefit is that you don't really need to train personnel in more exotic operating systems like z/OS.
The Ontario government made $64M in sales, with $106M in expenses. By comparison, the Alberta government made $77M in sales with $72M in expenses[1].

What's not mentioned in the article is if there's tax revenue seperate from the profits/losses of the government corporation. In Alberta, there were an additional $30M in cannibis taxes not included in their $5M profit.

As someone who works for a bank... no, not in my experience.

What is a problem is that the last time a lot of code was touched may be 5-10 years ago. That code may have started being written 20-40 years ago. It may well have been maintained by people who think "if it was hard to write, it should be hard to read" or "documentation is for the weak". It definitely will have been written when the cost of a gig of memory and storage was many orders of magnitude higher than today (indeed, last time I priced memory for a mainframe, a Z10, it ran to $10,000 a gig); hence terseness in everything from table and column names through stored data and everything else was prized. Dropping from COBOL into assembler is not uncommon for critical path performance.

Making any changes will be a week of coding and three months of working out the what and why of the code, because the last person who worked on it retired a couple of years ago.

When I got a modern LaserJet at home (my LJ5 lasted forever), I intentionally got one with Ethernet, and without WiFi.

But all the cloud-y firmware features of the new LaserJet looked so sketchy, I decided not to connect the printer's Ethernet to my LAN.

Instead, I set up a separate little print server, which connects to the printer's USB.

Of course there are still vulnerabilities, but at least now it's not as overtly sketchy.

Turns out things are a bit more complex than "survival rate after being hit by a car at 40 km/h in the front":

- Both cyclists and motorists tend to take slightly more risks when wearing helmets (cars give less distance when overtaking).

- Mandatory helmets means fewer people cycle, so cars are less used to cyclists leading to more dangerous situations.

It's been discussed many times on HN, and there is no clear-cut answer. Some research (I can't be bothered to find it all again, sorry) suggests it doesn't make a difference, other that it makes things slightly safer, and others that it makes it slightly less safe. On balance, it probably doesn't make much of a difference.
I agree that the hypotheekrenteaftrek should be (and is being) phased out, but it seems to me that the monetary policy of the ECB is a big factor in the current housing bubble as well -- for years they've been lowering the interest rates in the name of stimulating inflation, which also drove up housing prices.
You can honestly find a ton of good resources with local or national home schooling organizations or parents.

I intend to homeschool my kids, and I’ve never met a more intense group of parents when it comes to their childrens upbringing and development than when I went to the Arizona homeschooling conference the last couple of years.

Even if you have no intent to homeschool your toddlers, the resources and ideas for activities and at home development is pure gold in my opinion.
I clearly don’t. It’s inexplicable to me why able-bodied people in a country with a birth rate below replacement rate since 1977 should expect to be able to stop working. It doesn’t matter how you structure the retirement system, the math doesn’t work.
Point of caution before using adnauseam: I installed and used it on 3 devices for about 6 months a few years ago. I have seen an increase of about 50 fold in the amount of targeted spam phone calls and physical mailers I receive since that time and they've only started to subside in the last year. I can't prove but highly suspect it's a result of my name getting added to a lot of lead DBs as an interested potential customer due to adnauseum ad clicks.
The engine itself doesn't feel like the interesting part here (nobody will probably ever write another game in it, nor developer it further). It's one of those "what matters is the journey rather than destination" things.

But at least I'm finding the other deliverables from this project fascinating. Especially the blog posts are really good.

This is actually pretty important. I did a 50 miles ride once and after about 30 miles the only way I could continue was by removing my helmet. My head was overheating otherwise, and every mile I continued with the helmet on, I was getting dizzier and dizzier. Only after I removed my helmet was I able to continue the ride without any negative effects.

I still advocate for bicyclists wearing a helmet, but inside that recommendation is the reality that the standard American helmet I was wearing was causing me to overheat and suffer negative side effects. The only way I made it to my destination was from removing the helmet and taking the risk of crashing and suffering a major head injury.

In that way, helmets are very different from automobile seat belts.

> typical cyclists speed inside city centers is more like 8 miles an hour

Is this referring to average speed? I suspect that this doesn't take hills into account. In my rides with a loaded trailer, my usual average speed is about 11 to 13 mph and my top speed on downhill sections ranges from 20 to 25 mph. My uphill speed is about 5 to 7 mph.
when i try to explain complicated topics to people not familiar with them, i try to simplify instead of going into detail.

one thing that worked nicely for me in the past when explaining domains:
full domain name: actual internet address of a company, like a street address of a store.
google.com is equal to streetname.number

if you know the number (eg tld) of the house, you just go there directly and enter the store.

if you do know the street (google), but do not know the number of the house (.com) you need to stop and ask someone for the way, and this is what google.com is for.

usually the big aha effect is that google.com is an address which leads you to a page that allows you to find other addresses.

going to google.cn (or whatever country you like) might help too, explaining how google has both .com and .cn and .nz and so on, all different "storefronts" of the same company, catering to different countries.

once that is understood, and if it was easily understood, maybe explain how the top bar (in most browsers) can be used for both searching for addresses and to input addresses directly,
then set the default search engine to duckduckgo.

hope that helps :)
It's really weird to me that people are generalizing this by nationality. Sure, a lot of supermarket strawberries are terrible. They also frequently (but not always) come from outside the US. Some are ok, and some people get flavorful ones somehow, because I've had excellent quality ones with dessert in a restaurant. Also, there are farmer's markets and stands, even though I'm not in the habit of going to them.
From comment in link: "So you reinvented the T-tree, plus some Straw Man graphs and some comments on how you're smarter than the entire CS field. Congrats?"

Yeah, an incidentally-optimal-with-a-certain-architecture algorithm is great as long as you can count on the architecture remaining constant.

"Cache oblivious" are one seemingly better approach since they're optimal to some degree on a wide range of cache structures - but no theoretically as fast purely in-memory structures, if they are somehow in a single memory type.

"Architecture aware" trees are yet another scheme, if the program can discover the architecture.

Of course, a lot of algorithms are going to GPUs and how these structures relate to GPU processing is another thing I'd be curious about.
