wojt_eu··on Ask HN: Move to product management at 35?
I've read how being responsible for family make employees plan their work better because they want to get home for the dinner, how it makes them more responsible or loyal – but that's the first time I hear about parenting experience directly affecting management skills. Some similarities are obvious now that I think about it – you want to help them grow and flourish. You set expectations and put boundaries while avoiding micromanagement and try not to spoil internal gratification with bribes. Well, except firing – you don't fire kids early due to lack of culture fit.
wojt_eu··on After Decades of Growth, Colleges Find It’s Survival of the Fittest
This shows correlation but not causation. Hypothetically: people with certain background (social class) and traits (IQ) are more likely to go to college, and they would fare as well or better without college. I'd be very interested in stats of lifetime earnings difference that was corrected for selection bias.

I love Q&A on that page:

Q: We are talking 'digital' audio, correct? 1's and 0's ... not analogue audio that really benifits from serious quality??!!!!

A: This cable is such good quality that it supports the transference of 0's, 1's and 2's.

Q: If I wrap this cable around my arm, can I punch faster than the speed of light?

A: No, that requires their 16 meter length version.

wojt_eu··on What Needs to Happen Before Electric Cars Take Over the World
I already feel nostalgic about gas-powered cars, their place is alongside steam locomotives as movie props and tourist attractions. Imagine people doing gas-punk cosplay in a couple of decades.
wojt_eu··on Senators push to ditch social security numbers in light of Equifax hack
Then the bank has incentive to shift responsibility back to you, e.g. by requiring withdrawal request to be signed with your private encryption key. And you have an incentive to care about security of this key.
wojt_eu··on Company gives non-smokers six days holiday to compensate for cigarette breaks
Research that contradicts benefits of frequent physical activity for office workers? Paint me surprised. Can you share some links?
wojt_eu··on Interview with Mr. Money Mustache
I don't see that much of consumerism advocacy here. Quite the contrary - being frugal to extend runway, achieving ramen profitability etc.

Also with rampant ageism in tech you do need to retire before 40 /s

Poland has Central Anticorruption Bureau (CBA) and Internal Security Agency (ABW). They both report to Prime Minister, while Police reports to Ministry of Interior and Administration).

And then replicate the experiment.
wojt_eu··on Photographer wins 'monkey selfie' legal fight
Well, the monkey seems to have borrowed the equipment and outsourced technical parts of the process to a specialist and focused on the creative part. Pity the camera owner did not sight a contract, he could have charge a fee for assistance or even negotiate some royalties.
wojt_eu··on Wind Energy Is One of the Cheapest, and It's Getting Cheaper
If we increase our energy consumption 100-fold this estimation of net loss in wind would approach 1% which sounds bad. I guess we might need wind protector after all.

wojt_eu··on Right to Privacy a Fundamental Right, Says Indian Supreme Court
> Nazi's are an easy target. The problem starts when things are not as clean cut -- when actual politics are involved, as opposed to crude stuff like "exterminate all jews" and "blacks are inferior", etc that Nazi's might say.

It wasn't so clean cut back in Germany in the 30s either, there was always some other rhetoric: being "stabbed in the back" in WW1 by internal forces, using emergency powers to deal with effects of Great Depression and threat of Marxism.

[Update]

I encourage watching snippets of Hitler's speeches (with translations): https://www.youtube.com/watch?v=AnpTWKKWQ1o. Strip away swastikas and heils and these could be used by populist politicians today.

Even if we succeed in prosecuting hate speech there will still be plenty room for fanatics to come to power.

Click-bait titles can be moderated and edited more easily.
wojt_eu··on The Irrationality of Alcoholics Anonymous (2015)
One thing I've heard AA does right is asking attendees to talk about each their recent drinking acts and what preceded them. This forces some to realize their patterns and triggers for the first time.
wojt_eu··on Ask HN: Why is there no way to prevent scroll-jacking on a webpage?
They install more analytics, A/B testing scripts and survey popups to figure out why.
wojt_eu··on Lessons I’ve Learned from Three Million App Downloads
As I understood the comment, the purpose of mentioning race and appearance was only to stress that just wandering at night caused the harassment.

I think this also implies syngrog66 acknowledges that people are also harassed based on their race and fitting certain stereotypes.

wojt_eu··on Former Silicon Valley CEO Indicted for Allegedly Defrauding Employees of StartUp
After a couple days the fraudster could claim that the wire transfer bounced, take another two days to check with their bank. Then they could say the problem is on recipient bank's problem with SWIFT/BIC code format and pretend to attempt the transfer again.

They might even go as far as actually commission the transfer in front of the recipient but then cancel it in the evening before it's cleared.

Another way to buy some time could be to send transfer for one percent of the amount and then claim it was a mistake with decimal point.

I guess this could be stretched to two weeks before recipients are convinced of the fraud.

One word; Hummus
wojt_eu··on Ultraconserved words in use since the last Ice Age
The word "hammer" changed quite a bit, but I still find it interesting that it origins from Proto-Indo-European word for stone: https://en.wiktionary.org/wiki/Reconstruction:Proto-Indo-Eur...

It still sounds somewhat familiar to modern slavic words for hammer: https://en.wiktionary.org/wiki/kamień#Polish

wojt_eu··on On the Unhappiness of Software Developers
In general it's about pressue to get the main task done quickly. I thought of some common reasons I feel this pressure:

  - external, e.g. bug hurting our clients.
  - feeling bound by an overly optimistic estimate, like couple hours vs. a week
  - can't focus, procrastinate and then rush to get the work done
  - imposter syndrome and constant feeling that I should have done my assigned task long time ago
  - personal issues forcing me to take some time off and delaying shipment
  - having already spent considerable time in some other rabbit-hole, especially without asking for permission 
  - misunderstood something, wasted lots of time implementing wrong thing but don't want to admit
  - scope creep, a feature that's too big and too long in not-yet-ready-for-deployment, risk of interruptions, merge conflicts and being too big to test properly grows
The first one is fundamental and sometimes things are simply urgent. Addressing rest of them is an ongoing effort.

Without this kind of pressure I often find solving problems like debugging library code or git forensics quite fun.

I'm fine with fine-grained time accounting. Part of a decade of remote freelancing. Nowadays I do it habitually without being required.

wojt_eu··on On the Unhappiness of Software Developers
That gets my goat is a problem that gets in a way of solving problem I was tasked to solve.

An example would be the test suite segfaulting on my machine while I'm responsible for hunting down a nasty bug. Often I'll take a stab at the distracting problem, e.g. reinstall Ruby and gems with native extensions. If that doesn't help

I'm faced with following choices (and due to time zone difference I need to decide before my manager gets online):

- give up investigating and suffer the segfaults (time already spend is a sunk-cost with nothing to show) - disappear into segfault rabbit hole, all the time stressing that I should be doing something else

In isolation I'd be happy to focus on solving either problem.

wojt_eu··on Millennials are less keen than previous generations on illicit drugs
My first guess would be that being poor relative to peers is more stressful and depressing and relates to more substance abuse problems. When hardships are shared among whole generation it could affect them differently.
wojt_eu··on The Advantage of Being a Little Underemployed
My work to/from work is 25 minutes. I have a habit of walking rather fast but noticed I often get worked up about some issue that's neither urgent nor very important. Only when I force myself to walk at more leisurely pace I find it refreshing.
wojt_eu··on Why Amazon is eating the world
The main point is that Amazon's advantage is exposing divisions to external competition. Without it "internal supplier gets complacent with a captive, internal customer."

However later paragraph says:

> The key advantage that Amazon has over any other enterprise service provider – from UPS and FedEx to Rackspace – is that they are forced to use their own services. UPS is a step removed from backlash due to lost/destroyed packages, shipping delays, terrible software, and poor holiday capacity planning. Angry customers blame the retailer, and the retailer screams at UPS in turn. When Amazon is the service provider, they’re permanently dogfooding. There is nowhere for poor performance to hide.

Doesn't it contradict earlier point?

wojt_eu··on Warren Buffett says health care costs are a bigger problem than corporate taxes
“If you go back to 1960 or thereabouts, corporate taxes were about 4 percent of G.D.P.,” Mr. Buffett said. “I mean, they bounced around some. And now, they’re about 2 percent of G.D.P.”

By contrast, he said, while tax rates have fallen as a share of gross domestic product, health care costs have ballooned. About 50 years ago, he said, “health care was 5 percent of G.D.P., and now it’s about 17 percent.”

wojt_eu··on Stop the Daily Standup Meeting
Half an hour meeting with 8 developers takes 4 developer hours. This is often enough to give manager a pause.
