L_Rahman··on Ask HN: Who is hiring? (April 2020)
Just a heads up that Chrome triggers a privacy warning and blocks navigating to https://sureapp.com. You might have a problem with cert management on the domain.
L_Rahman··on WireGuard 1.0 for Linux 5.6
I'm looking forward to the days when we have good user management for Wireguard. It's so hard to scale it across just my family right now.
L_Rahman··on WireGuard 1.0 for Linux 5.6
I was in a similar situation. Port forwarding worked perfectly. In my case the server I was trying to access was behind an ISP (Comcast) managed NAT so I had to go through them to open the port. Much to my surprise they were extremely helpful and understanding of the request.
L_Rahman··on For Seoul’s poor, class strife in ‘Parasite’ is daily reality
The Chinese middle class is still in its first generation and mobility has stagnated for just a decade so it's still early. It'll be interesting to see whether tolerance for the government survives the upcoming economic slowdown.
L_Rahman··on For Seoul’s poor, class strife in ‘Parasite’ is daily reality
Which they did. The movie mentions an unsuccessful attempt to be a franchisee of a food chain that later turned out to be a scam. That ended up bankrupting the family.
L_Rahman··on Things I Learned from Five Years in Climate Tech
Would not be a hacker news climate thread without someone jumping in immediately with nuclear.

I am not opposed to the technology in a meaningful way but the problem is that the conditions in which nuclear can thrive - regulatory scheme, public perception of climate change risk, long time horizon infrastructure development, $$$ - non nuclear renewables easily outcompete.

I wonder how the nuclear folks think about this. The tech doesn’t exist in a numerical vacuum of efficiency and dollars per watt. It lived inside a complex ecosystem within which it doesn’t really seem competitive.

L_Rahman··on Is Catalina a Good Upgrade Yet?
Wait this is a bug? It happens to predictably after every update that I thought it was an intentional design pattern.
L_Rahman··on What happened to Mint?
This is the main reason I stopped using it. I don't know if they pushed an update to transaction tagging, but it got really bad all of a sudden making the product much less useful to me.
L_Rahman··on The Cruise Origin
The subpar navigation and traffic avoidance are a function of road design in high density environments.

We know how to make that go away: create separated bus only right of way with traffic light synchronization.

L_Rahman··on Ask HN: I don't want to be a worker any more I want to be a professional
The way you’re feeling is not just about your role as a computer worker but as a worker in general.

There are three ways to break out of this:

1. Play the game inside the system - work “really hard”, be “visible”, demonstrate “strategic leadership” inside some game space like BigCo, VC-backed flavor of the month. You will still likely be a cog, but with luck you might be able to influence the edges of the game.

2. Find an orthogonal vector into doing computer work - look outside the set or opportunities typically presented to you and instead look at problems you care about and whether you have an edge that lets you put together a team to go solve it. Note that this works best with at least one other person, you need someone in the trenches with you to keep morale up and even if you’re both talented at the construction and people end of things it’s better one specializes in each.

3. Organize your fellow workers - we are quite possibly the single best paid, most powerful group of workers in the history of humanity. There are efforts to collect this power so that we may actually influence the decisions that get made.

One last piece of advice, the way you feel in this moment is where anyone who has ever done anything great has started. There is no assurance whatsoever that you will achieve what you initially set out to build. But what you can control is whether you try to do something or accept the existing structures as they are.

Good luck!

L_Rahman··on Ending Legacy Admissions at Johns Hopkins
And given the size of Bloomberg's donations during his lifetime, I suspect the university also has assurances for more gifts in his legacy allowing to close the gap from former alumni no longer donating.
L_Rahman··on Hidden Dangers of the Great Index Fund Takeover
The actual mechanics of owning the shares is incredibly complicated. It’s unlikely that any of us have index fund holdings that represent integer share counts.

Handling stocks when they move in and of the index without spiking the price is a finely calibrated, high skill trading desk action.

L_Rahman··on L.A.'s Lost Transit
As a New Yorker, I had really high expectations for the Tokyo subway system when I was there for three weeks but I was entirely underwhelmed.

Japanese public transit is actually completely broken in ways that are appalling:

1. Line transfers are user hostile within network

Even if you stay inside the same operator, like Tokyo Metro, making like transfers is an ordeal in distance, steps and most importantly cost. It costs 1.5x as much to go 2+3 stops than to go 5 stops on the same line.

2. Line transfers across networks are actively discouraged.

Even if the most convenient mode is for you to take two trains from two different companies (say Keihan and JR) they’ll charge full price rides for each.

To make it worse every company intentionally makes way finding to a competitor line hard. Get off the JR line in Osaka station and try to transfer to the Keihan line. It’s impossible.

3. Peak hour service is the single worst public transit experience in the world with the possible exception of the BRT in Colombia.

This was the real test of the system for me. I used to live along the L, which post CBTC has become one of the best performing subway lines in the system. It’s really bad at rush hour. People are jammed in.

It absolutely pales in comparison to a Japanese rush hour train which in my opinion is actively dangerous.

All of the “Japanese discipline and order” doesn’t buy them better headway either. It really does feel like 2 min headway on rush hour heavy rail is the max and neither Tokyo nor New York can do anything about it.

4. Station distances are far apart and last mile is terrible

Unless you’re really lucky and happen to do things right by a metro station, everything will be a 10-15 walk even within the core areas. Compare this to NY where we average a stop every 10 blocks even in the outer boroughs and can go as low as every 4 in midtown and downtown.

5. Entering and exiting the subway is a chore.

Either you have to deal with the terrible compromise that Japan made in privatizing its rail - giant maze like shopping malls that you have to walk through to get to the subways, or if you’re lucky a long underground passageway from a side street. There’s no cardinality, no orientation after you exit, the city is just a blob with buildings splattered across it.

I used to think Tokyo was the pinnacle of urban design - high functioning rail, zoning that allows for affordability - I am sad to say it fails on a number of key dimensions.

It is the most energetically “dead” big city I have spent time in and without a radical change in the norms of Japanese society it will remain that way.

For $2.75 I can ride all the way from Van Cortlandt park to the Far Rockaways, I can take as many trains as I want. I can connect with the vibrancy of the culture of our city. Will the train break down? Maybe. Will rats scurry across the tracks? Without doubt. Does the system smell like pee? Most of the time. But it is alive and thrumming. I will take that every day.

And if our dear leader Byford can get his way, it’ll run really well too.

An aside: the system that I think New York should actually be envious off are Hong Kong and Taipei who have both built excellent, reliable systems in cities that are vibrant and welcoming.

HN needs to tone down its Japan weeb levels.

L_Rahman··on L.A.'s Lost Transit
yes, which is why building housing and transit has become a nationwide failure
L_Rahman··on Clearview AI helps law enforcement match photos of people to their online images
if I leave my apartment in NY without any devices and transport myself exclusively with a metrocard paid for with cash, I can move myself across the entire city without being surveilled

I will however probably walk into at least one photo that gets posted publicly in the course of a day.

L_Rahman··on Autocomplete as an Interface (2015)
Fish autocomplete when navigating directory trees is a life changing thing.
L_Rahman··on Cable Haunt: A critical vulnerability found in cable modems
similarly lucky as the other person who replied

checked the spectrum website for compatible modems available on the market, ordered a DOCSIS 3.0 Motorola Surfboard and when the technician came in, he pulled cable across our (admittedly tiny) apartment to where I had all my networking gear mounted to the wall on 3M strips

great experience

the actual internet itself, not so much, but that has a lot more to do with the terrible nest of interconnects in older apartment buildings in New York than Spectrum's upstream network capacity

L_Rahman··on Day of week of procedure and 30 day mortality for elective surgery (2013)
This depends on the kind of meeting you're having. If it's a negotiation with a counterparty, then absolutely schedule for right after lunch. It'd be better if they were a little insulin drowsy after lunch. Ideally you'd be buying them lunch, eating little (or mostly vegetables yourself) while they enjoy an expense account meal.

On the other hand if it's an internal meeting with your team, you want to get them at peak alertness, 10-11 (people settle in for the day, but not hungry for lunch yet), 230-4 (the post lunch blood sugar swing has settled down but people aren't itching to leave just yet)

L_Rahman··on Algorithm Removes Water from Underwater Images
I agree with your general argument, but golf courses are such an unfortunate example. They're the one use of public space that would be many orders of magnitude better for the community if they were used completely differently. A park would be a good start, but there are so many more.
L_Rahman··on Avro Arrow blueprints on display after sitting in man's home for decades
Had RIM realized the game was up when Android started eating into their marketshare and went all in on BBM as a messaging platform we would probably be talking today about BBM marketshare relative to MS Teams and Slack.
L_Rahman··on Contractors use shell games to hide owners, cheat taxpayers
Ah but if you propose legislation to change the acquisition process then you're taking economic opportunity away from veteran/disability/minority/[disadvantaged group part of x party's coalition] and therefore are evil.
L_Rahman··on A sticky problem that evaporated
I have pretty much staked my entire career on my ability to do this. It's also quite well compensated when you do it as a product manager.
L_Rahman··on America's Biggest Milk Producers Are Going Bankrupt
Tech and finance businesses are also horribly run. There's no evidence suggesting managerial or process excellence in technology companies. The reason finance and technology companies are profitable has everything to do with the nature of the product they create and the leverage it has in our society today.

Finance is famous for making people sitting at their desks all day waiting to get a deck at 11AM to put in logos with the correct resolution.

L_Rahman··on America's Biggest Milk Producers Are Going Bankrupt
It's hard for the NYTimes to run stories on the evils of private equity when their employees and owners are completely intertwined with the people who work in that industry.

I can't overstate the degree to which all the different industries in New York socially overlap. The degree of separation between someone who works in technology, media, finance, publishing and advertising is 0 or 1. Those relationships become marriages, friendships, acquaintances, people sitting next to you at charity dinner.

Perhaps most critically the Times is a family owned business, the owners are billionaires, the current owner is also it's publisher. They have no interest in poking around the fundamental mechanics of how rich people operate in this country.

Shiny stories of fraud or insider trading or whistleblowing? Absolutely. But questioning the core mechanics of capital, especially capital centered in New York operates would never happen.

L_Rahman··on Firefox 72.0
I'm honestly surprised that we aren't talking about tab behavior here. Literally the only reason I keep using Chrome is that no matter how many tabs I have open, they're all visible at the top.

There's visual persistence of state. On Firefox, even with the trick of reducing minimum tab width, my tabs overflow and I have to click through to get different groups of tabs. It is utterly maddening and I don't know why every other browser refuses to do Chrome like tabs.

Why the continued choice to violate the first rule of UI design which is to keep things in the same place?

L_Rahman··on Major union launches campaign to organize video game and tech workers
Sadly they might actually be. It's game theoretically an efficient strategy because they can extract so much before the workers unionize that it'll still be cheaper than compensating them fairly all along.
L_Rahman··on Major union launches campaign to organize video game and tech workers
Public sector unions are a completely different ball game than private sector unions.

I whole heartedly believe in worker organization and believe that tech workers should unionize, but it is also true that in a lot of different pieces of this country public sector unionization has been an unmitigated disaster.

In any niche of our society that is not legible to the average person, public sector unions + the morass that is local politics in the US creates a downward spiral between public sector union workers and the politicians they bring into power.

The subway in NYC for example is broken for a number of reasons, but high on that list are the efforts of the transit worker union to block improvements in operational performance and their lobbying for Andrew Cuomo who might be one of the most transit hating governors in the last 100 years of New York politics.

L_Rahman··on Products I Wish Existed
This is the growth angle for pretty much all of the IDAAS (Identity as a Service) players in the market that are not AD. Will be interesting to see how it evolves.
L_Rahman··on A Next-Generation Trash Can
Private vehicle drivers in NYC are a special class of selfish and low integrity city residents.
L_Rahman··on A Next-Generation Trash Can
the extremely radical move would be to pull a Taipei - you can't leave your garbage on the street, the truck just comes everyday at different times and you walk to the truck with your garbage

time variation means people's different work schedules get covered - whether you're at home in the morning, afternoon or evening you'll catch the truck 2x a week

if you live in an apartment building, it makes really good sense to collectivize and hire the work out to someone or share the shore between neighbors depending on socioeconomic bracket
