samsonradu··on Tesla drops 7% after Goldman Sachs says the stock is worth $180
GS is somewhat notorious for this kind of manipulations: http://www.rollingstone.com/politics/news/the-great-american...
samsonradu··on Take Naps at Work
Google being Google is a bit different, but I'm sure there are a lot of companies where some low-productive employees who've been checking Facebook all day will point fingers at you for sleeping during the butt-sit hours.
samsonradu··on Take Naps at Work
Curious if you were able to do the same? From what I've seen asians have this ability to pretty much sleep anywhere, planes, trains, buses anything. The crappy chairs and noisy engines don't seem to bother them.

I don't think I could ever fall asleep in the lunch break, the morning coffee and the light outside doesn't let my brain go off.

EDIT

I really don't mean to offend anyone, just curious whether the ability to fall asleep in uncomfortable environments is something asian-specific.

samsonradu··on Etihad allows flyers to bid to keep adjacent seats empty
> What's really going to matter is how it's executed. If someone bids $100 to keep a seat empty and the flight is empty, do they still get charged the $100? Or is it only when there's a limited number of empty seats and more people that will pay to have an empty seat next to them.

For sure they will, and probably that's what they are after. Think of it like this, when you pay for an economy seat and get 2 adjacent seats for free because the plane is half empty you're basically winning the lottery since many travellers are randomly assigned. The airline will monetise on this from now on by opening up the bids.

It's very interesting also to see to what degree prices will go up since this would create some scarcity. The airline is probably happier to accommodate as few passengers as possible due to the extra passenger overhead (check-in, bags, service) though the math is quite hard considering upsales and all.

All in all, I have always been fascinated about the complex problems the airline industry is solving and this only adds more to it. Would really like to see the software implementing all this.

samsonradu··on On Starting a Software Business
> I feel like if I'd learned web development five years ago I wouldn't know anything about it today.

This is a wrong assumption. Web development just gives the feeling of moving fast, it's not really the case. The foundation of web development is roughly the same as 5y ago. Most things from the http protocol, web servers, data storage, authentication, websockets etc. still works the same. Give or take a few UX and state-management tools and we're not that far into the future.

Also due to the huge investments in the web during the past decade(s) things should get slower because of legacy issues. Think fe. how long it's taking browser vendors to dump Flash or to adopt WebRTC.

samsonradu··on US quits Paris climate pact
Well, not that I am defending him, but in his speech he said the deal is a burdain on the US industry while China and India are polluting as hell. This is something that might be factually right, but still not something to aspire to.
samsonradu··on U.S. military is expanding special forces operations in Africa
A conflict with the US would have been pointless I assume due to geographical reasons, very hard to send troops over. Meanwhile Germany was posing a threat quite nearby. But indeed there were very complicated times and it's hard to blame someone explicitly.

I agree with you about the King Edward material, feels a bit conspirative to me too. Although some political and economical points there make sense.

Thank you for the book reference, will check it out.

Btw, this discussion is a bit discouraging to me since I realise that not even after 100 years we can properly agree on some facts. Tech giants fighting fake news will have a big challenge.

samsonradu··on U.S. military is expanding special forces operations in Africa
From my understanding the problem was that Germany was growing very strong and threatening Britain's domination.

An interesting book about the topic is The Great Illusion By Norman Angell [1]

Saying a bunch of students started WW1 is quite absurd.

I did find some material pointing fingers at King Edward though, might want to take a look [2]

samsonradu··on Ask HN: Starting a project today, which web framework would you use?
Yii2. React on the front if the UX really requires it.
samsonradu··on The Boring Company FAQ
The Greedy algorithm at work.
samsonradu··on Why is React is taking over front-end development?
> React is just JavaScript, there is a very small API to learn, just a few functions and how to use them. After that, your JavaScript skills are what make you a better React developer. There are no barriers to entry. A JavaScript developer can become a productive React developer in a few hours.

This is a valid point. Maybe not a few hours but it clicks with developers after a few days. But then there is also the very good documentation and an already big community. Also Facebook backing it is encouraging for mid-sized companies to use, which don't expect breaking changes any time soon.

samsonradu··on Ask HN: What's your working day like?
Same here, except that I need the alarm. Also exercise after work.
samsonradu··on Understanding Node.js Event-Driven Architecture
Here you can read about the advantages of using Promises, it s very interesting, though a bit long. https://blog.jcoglan.com/2013/03/30/callbacks-are-imperative...

Promises are easier to compose because you can pass them around as values. Meanwhile callbacks are used only for their side-effects, they do not return anything.

samsonradu··on The great British Brexit robbery
> I believe the one major change has been about trust in institutions. It used to be that census, or unemployment data was, for the purposes of political discussions, assumed to be accurate.

First question that comes to my mind is How can you tell? I assume it was even harder back then to get your hands on real data. What was stopping the political elites back then to mangle the unemployment data when needed?

samsonradu··on Japan Shows the Way to Affordable Megacities (2014)
Right, Tokyo is very wide-spread. I believe it's the incredible infrastructure that allows people to commute to work easily. There is surprisingly little traffic for a city of that size.

Leaving Tokyo for Kyoto by train I kept seeing apartment buildings and houses for the first 50km or so.

samsonradu··on The great British Brexit robbery
There have been a lot of speculation and finger pointing at social media platforms for influencing high-level decisions. What I'd like to ask the elders here on HN is: Wasn't this always the case? Were elections in the 70s 80s all fair and fact-based? Were not political parties using information to their advantage and for pushing their own agenda?

Because to me it seems that only the tools have changed, rest is pretty much played by the same book.

samsonradu··on Apple plans to spend $1B to support advanced manufacturing jobs in the U.S
I know, but it can start with bigger taxes on properties (and better zoning laws). People and investors should be stripped of the idea that buying a house provides a good return. Lowering the leverage when buying a house would also help push prices down. Foreign buyers should be taxed more to avoid speculators.

I don't think food is a problem though, western EU food prices are not smaller.

samsonradu··on Apple plans to spend $1B to support advanced manufacturing jobs in the U.S
I think it's not xenophobia, the biggest problem is actually wage inequality. It s quite suprising that the US, with all its prosperity (gdp per capita) doesn't have a huge safety net, on the contrary. Meanwhile US corporations and individuals, same ones that outsourced the jobs, have more cash at hand than you can pronounce.

I sometimes believe it lacks a bit of socialism.

samsonradu··on Apple plans to spend $1B to support advanced manufacturing jobs in the U.S
This is quite objectively true. Take a 50% paycut but along with that also cut down the cost of living. Something like Germany today, wages are smaller than in US but the costs of living make their citizens happy(er).

Then there will be less wage discrepancy compared to China and co and jobs start coming back.

samsonradu··on Why Germany Still Has So Many Middle-Class Manufacturing Jobs
Right, the Euro took away other countries ability to manipulate their currencies and forced them to play fair in the trade game where Germany is king. Besides they also have a free market (EU) to sell to, while outsiders have to pay tariffs.

As for the other countries, all they can do is cut down importing I guess?

samsonradu··on Exercise 'keeps the mind sharp' in over-50s, study finds
Did you consider picking up a sport? Say squash, football, basketball, anything? I can see why weights are boring, running is also kinda meh imo.

But sports is motivating for me, I see all those footbal stars on tv and I'm dying to try the moves, the drills and get better at it.

Also if you pick up a singles sports you probably should get a coach to set you on the right path in the beginning, you'll like it even more.

samsonradu··on McDonald's Real Estate: How They Really Make Their Money (2015)
Really glad you brought this up. It was indeed an interesting movie but I didn't really have the time to compare it with the facts. How much of what we saw was actually accurate?
samsonradu··on Programmers are most likely to work from home
I like working in the office too, working from home is boring as hell and I did it for years. But it s the commute, it kills the little free time you have in the evenings. You get back home later and much more tired.

I still choose to work from home one day every week or two in order to take care of various other stuff like going to the dentist or checking up the car.

samsonradu··on Uber banned in all of Italy
Well they are not profitable anyway are they?
samsonradu··on Uber banned in all of Italy
Uber is breaking the anti-dumping laws there. Fixing price to be cheaper than local taxis and burning money. That's unfair.
samsonradu··on It’s now illegal in Russia to share an image of Putin as a gay clown
Why has this been downvoted?
samsonradu··on Dimnie: Malware targeting open-source developers
Thanks, that's very interesting.
samsonradu··on Dimnie: Malware targeting open-source developers
How does it work? Any sources?
samsonradu··on Robinhood stock trading app valued at $1.3B with big raise from DST
I'm also looking for something like that. I have used Plus500 for a few months and didn't really enjoy it. I cannot lower the leverage (or that's what support says) and the overnight fees were eating up my profits.
samsonradu··on Show HN: Redux Offline – Build Offline-First Apps for Web and React Native
This is so true. Just apply the Redux idea of smart/dumb components but without actually using Redux. Higher level component(s) becomes smart and handles the state changes while passing down only properties to children.

Usually I start an app like this and when things get really complicated I add Redux and refactor the state management out of my top component.

MobX looks interesting, however didn't get to try it out yet, only briefly looked over it. I find it a bit annoying that they introduce even more syntax overloading - annotations - as if ES6/7/JSX is not enough already. Will give it a try on a pet project soon.
