LeftHandPath··on Show HN: I built a podcast app that skips over the ads
But advertisements in podcasts are commonly pre-recorded by the podcast host(s) - so the host would still be paid for the advertisement, before it goes online.

If the advertiser isn’t given any information about playback at ad time, then the revenue would not be affected.

LeftHandPath··on A Reality Check on Quantum Computers
People riding the bandwagon and generally talking about it like they're in on it when they don't know what a qubit or bell state is (or how to read braket notation).

It's a similar line to AI - if the people talk about it like it has the potential to (and eventually will) destroy the world, they probably don't know much about it (in that case they're conflating sentience with intelligence, and ignoring the word "artificial).

The people who are working on it right now will - like with AI - tell you that it's in its infancy, that its current applications are more limited than they are made to appear in pop-culture, and that (generally) things are harder and take longer than people pretend.

Which is exactly what the author of the WSJ article is getting at (because he's not a hawker - he knows):

> "There’s little doubt that, in the long run, computers that exploit quantum features of matter will dramatically enhance our ability to address useful problems. But we’re not there yet, nor is success guaranteed. For the foreseeable future we will have, at best, a “quantum advantage” in well-chosen applications, not “quantum supremacy” along a broad front."

LeftHandPath··on Amazon Braket – Get Started with Quantum Computing
I would enthusiastically recommend IBM Q [0] and the command-line variant of Hello Quantum [1] to anyone who wants to investigate quantum circuits.

If you start googling (or searching with your engine of choice) about Quantum Logic Gates, Bell States, et c., you'll pick up the basic concepts pretty quickly. Then you can follow the rabbit hole from there.

LeftHandPath··on Computer Architecture – ETH Zürich – Fall 2019
That's what I was wondering about.

Honestly I was thinking that some sort of integration where content creators could be directly contacted by advertisers - who would pay for in-video advertising by the content creator (this is more for personalities than for corporations) - and have a vetted way to be payed for their time / platform / ads would work (with companies paying to be part of that system). This would result in higher quality ads that are more beneficial to the content creator than the video distributor (a goal I view as equally good). And to benefit the companies advertising, you could create a tool where shorter clips of the advertisement could be sent back and forth, previewed, and approved as needed (if integrated with a payment system, this protects both parties from a bad deal).

I also think some, but not all, content creators would view paying for a small hosting company to store and stream their videos in the same way they view buying a new webcam or microphone.

LeftHandPath··on Computer Architecture – ETH Zürich – Fall 2019
I've actually started to hate YouTube so much (just for being terrible to content-creators and consumers, and supporting toxic videos (time watched is a ranking factor, promoting high-engagement "edgeline videos)), and so on and so forth) that I wanted to create a white-label HTML video player that would keep the benefits of a consistent, well-made UI but drop the publisher aspect of YouTube.

I don't think I ever will, but the world needs an alternative that has a good encoding/optimization (like switching to lower bitrates on slower connections), a unified interface (familiar no matter what site it's being used on) and that doesn't tempt users to write custom skins for the video player.

LeftHandPath··on An introduction to data processing on the Linux command line
Interesting.

For anyone who is interested in going a little deeper into data science, I’d also recommend the “Introduction to Data Science with R” series by David Langer:

LeftHandPath··on Designing Windows 95's User Interface (2018)
> the real product has little to do with the task you came to the site for, so everything is trying to distract you away from that task

This is really the biggest thing I had against the reddit redesign (and why I love the simple UI of Hacker News). It cleared away space for ads on either side, made the platform as a whole better suited to image- or video-content (dissuading users from using text posts on the site for discussion), and ultimately felt - exactly as you described - "distracting". It made it blatantly clear that the site was for upvoting pictures, getting inundated with political propaganda from whichever side is currently paying more, and ultimately wasting the user's time.

Facebook is feeling the same way.

I've literally gotten to the point where I separate "good content" from "time-wasting content" by browser - anything that I can consider educational, time-sensitive, or otherwise important (... I have a list of pinned tabs; Schwab, ThinkOrSwim, Financial Times, Bloomberg, The Economist, the Wall Street Journal) goes in Opera.

Anything that I save solely for my spare time goes in Firefox. All of my social media accounts go in firefox (google is the only thing I knowingly allow to track me between sites in Opera). Reddit and Hacker News go in Firefox (although sometimes I browse HN without logging in in Opera, so that I don't have to switch browsers to log into news sites with paywalls).

It makes it really easy to keep myself focused when I need to do something important, and it also makes it easier to live with some of the more annoying (but security-bolstering) browser settings I currently use.

LeftHandPath··on Hey, Tesla Fans: Drive the Porsche Taycan Before You Criticize It
Are they though?

The more I’ve read about human psychology - particularly about “flow” - the more valuable manually driven cars seem.

Similarly to how many people are actually happiest / have the highest sense of self-worth while at work (even though they’d scream otherwise), a lot of people are able to relax and think freely while driving. And in general, humans seem to enjoy having control over G-force (whether jumping off of cliffs, flying planes, riding roller coasters, driving...)

Flow: https://en.m.wikipedia.org/wiki/Flow_(psychology)

LeftHandPath··on Algorithms were supposed to make VA judges fairer: it's far more complicated
> You get substantially more added to your risk score for being younger than 30 (13 points) than, for example, having been incarcerated five or more previous times as an adult (9 points).

I’m starting to be routinely disappointed by people blindly trusting ML / algorithms to “just work” and, often with disastrous effects, to eliminate bias.

Someone who can get pop-culture’s attention needs to do a fucking Ted Talk and explain why this is usually a bad idea.

Better yet, someone should do a preliminary meta-study of ML studies like this to look at how often they seem to exacerbate bias.

LeftHandPath··on Local-first software: you own your data, in spite of the cloud
Sure, any one company probably will - but there’s a whole market.

As soon as that one company abandons the local-first model, a gap opens, which will (usually, eventually) be filled by a new company offering local-first until that new company does the same.

As long as the companies don’t band together and agree to end it, there should be a company offering that model somewhere somehow.

LeftHandPath··on Interpol plans to condemn encryption spread, citing predators
Banning encryption is like requiring that all your walls be made of glass and that the police can search your home at any time, for any reason, without warrant.

A personal electronic device, and the connections made with it, are extensions of the person and their respective home. A literal ban on encryption is probably the single largest step any government could take towards becoming a dystopic, tyrannic, borderline-criminal entity.

LeftHandPath··on Trump releases rule forcing hospitals and insurers to disclose negotiated rates
> Also many Americans can't afford a checkup because they spend the money they do have on bullshit, it's not that we wake up one day and realize we don't have Medicare for all

Trust me, I agree with you more than you know.

Reddit just trained me to try and sound less like I'm blaming individuals for making poor financial decisions (if I want my opinion to be heard rather than downvoted into the ninth circle of hell) and to never directly state that I don't support (current interpretations of) medicare for all.

LeftHandPath··on Trump releases rule forcing hospitals and insurers to disclose negotiated rates
> Implementing the changes is likely to cost hospitals less than 1% of their revenue, an official on the call said. Hospitals could be fined $300 a day by the Centers for Medicare and Medicaid Services if they don’t comply with the new disclosure rule, officials said. The administration is also proposing extending the disclosure rules to health insurers.

Interesting. I wonder what that (1% revenue) is in terms of percentage of profit. I would've gone after the insurance industry long before I touched the hospital's bottom line - my grandmother comes to the US, whenever she has an operation, for a reason. That reason is that the money is here, the technology is here, and the best doctors from around the world often end up immigrating here.

But at the same time, plenty of Americans can't afford a basic checkup.

Ideally, we preserve the incentive for the medical and technology communities to come here (money) while reducing the immediate monetary burden on everyday consumers that need to access that healthcare.

The obvious middle-men are the insurance companies. Then again, this isn't a single-variable equation.

LeftHandPath··on Canada refuses visas to over a dozen African AI researchers
This is incredibly disappointing.

> Visa woes are common for academics trying to attend conferences in the US, Canada and the UK.

Sounds like there's a real market gap. Maybe someplace like Singapore could afford the risks (and handle the crowds). Australia would be a nice choice but they're pretty strict about letting people in these days (at least when I looked at both work and student visas a year or two ago).

Then again, they don't discuss or give evidence for any of the visa denials they suggest are given by the U.S. (and in fact, the primary subject of the article is currently based in the U.S.). It's definitely not what I expected, but judging by the issues they list, it looks like it's harder to get into Canada or the UK than it is to get into the US-of-A.

Maybe they should look south of the border next year.

LeftHandPath··on Supreme Court to Hear Google-Oracle Copyright Fight
Honestly, they need to put it into layman's terms.

The exposed function calls of an API are meant to be implementation-blind.

Let's say car-company A builds the first ever car that's operated with a steering wheel, gas pedal, brake pedal, clutch pedal, and shifter.

Then, Company B comes along and - both to create a complete control system for the car AND to potentially benefit consumers who are already familiar with those controls - also uses a steering wheel, gas pedal, brake pedal, clutch pedal, and shifter.

The steering column and its inner workings are completely different. The gas pedal activates a V8 combustion engine instead of an I4. The clutch pedal triggers a dual clutch for faster shifting between gears. The brake pedal activates disc brakes instead of drum-brakes.

The appeals court is, in effect, saying that Company B has violated copyright because, when faced with the same problem, they came up with a solution that looks very similar on the outside. They turn a blind eye - willingly or unwillingly - to all the new engineering that went on to improve the product and create a new expression of an automobile.

LeftHandPath··on U.S. Workers Show Little Improvement in 21st Century Skills
There's a mix of both. There are hardworking Americans - usually first- and second-generation immigrants and the older, wealthier families - that value education and hard work. And then there is the middle class, who was raised on entertainment, music, and media that romanticized apathy and disdain for education and the workplace. And there is the lower class, which has enough of its own struggles that I don't want to try to summarize their problems in just a sentence or two.

Either way, I do think that platforms like YouTube and Instagram give lots of influence to entrepreneurs - enough that Shark Tank started labeling some contestants as 'wanntrepreneurs' (wannabes) - and that the perceived value of self-driven diligence and the desire for intellect might become popular again. Actually, I think they already are starting to be popular again, especially among younger people.

> But American's have it in the their mind that the only way to gain skills is by going to a school and sitting in a classroom.

Ivory towers will come crumbling down in time.

LeftHandPath··on Nine-year-old child to graduate university
I'm not on quite the same level, but I was definitely quick enough to skip a few grades. Thankfully my parent's didn't let me - I wanted to at the time, but to be honest, the importance of social wellness is drastically understated by academic community.

Humans are animals, and social animals at that. If we don't give our brains social release, we're going to struggle.

LeftHandPath··on Ask HN: Do you write tests before the implementation?
I’ve actually found it helpful to start by writing tests, and then in the actual code, documentation (just about what the code does or should do), especially when I’m not entirely sure how to solve a given problem.

But for code that’s trivial to implement, it seems unnecessary...

LeftHandPath··on The MLM Epidemic in 13 Maps
> A fool and his money are easily parted. If those students didn't blow their tuition on MLM garbage, they'd have blown it on something else. I'm sure there's a kid somewhere who blew his tuition making ridiculous option trades based on something he read on r/wallstreetbets.

Just because you're getting downvoted, doesn't mean you're wrong. Caveat emptor.

That said, the kids who make the options trades probably lose more than the ones who fall for the MLM scams...

LeftHandPath··on The 16-Inch MacBook Pro
I'm starting to believe that 2010 to 2013 were peak Apple, at least from a consumer product perspective.
LeftHandPath··on The 16-Inch MacBook Pro
The worst part is that, looking at the image, it looks like there's plenty of room to have both. The trackpad is massive - why not shrink it a little bit, move the keyboard closer to the front, and add the touchbar on top? Hell, why not do that to transition for a model lifecylce or two and then go ahead and replace the function keys altogether once people have had time to adapt?

(Of course, the answer is that this is a laptop that's marketed to freshmen film and music students, not professionals or engineers...)

LeftHandPath··on Tax Cuts Increase Income Inequality (WSJ)
While I am not personally a fan of ultra-progressive tax rates on the ultra-rich, I do think it’s time that conservatives start considering higher taxes.

With the top 400 income earners having paid an average of 23%, vs the nationwide average of 25%, it seems that taxes must be revised, if only to satisfy public opinion and prevent civil unrest.

What does HN think?

LeftHandPath··on The FBI Is Tracking Our Faces in Secret, and We’re Suing
It's interesting that people worry about "the basilisk" and all of this happening with AI, but not about the fact that future governments and revolutionaries are equally likely to look back on old data and judge you for it - and have a much greater capability to use that data to do you harm.
LeftHandPath··on By removing “extremist content,” platforms are purging human rights evidence
The number of times I've taken a google search that gave me useless results, copied-and-pasted it into duck-duck-go, and immediately found what I'm looking for, is astounding.

I do think that they are starting to lose the power-user userbase when it comes to browsers and search engines. But their email, docs/sheets/whatever, drive, and now their DNS registrar services are all cemented into business flow.

It makes sense. They don't need the power users - they need the most users. As long as they have the most users, businesses (where the power-users are working) are going to use ancillary services like Google MyBusiness, Google Analytics, and embrace google-backed (and ranking-factor) tech like SSL certificates and progressive web apps.

LeftHandPath··on Tesla Q3 Financial Results
I remember doing a due-diligence on Tesla during the Oil Crisis of 2015. The stock was at 195 or so, the company hadn't released anything other than high-end sedans, and the cars were still sold in stores.

If you went to their website, you saw that they were planning to have a $35,000 vehicle for sale by 2018, with rapid charging stations set up across the country (forming a corridor for coast-to-coast travel), where Tesla owners would be able to charge for free. And furthermore, the leadership - Musk - had shown his worth when he put his last dimes into PayPal just a few years earlier.

I said it was a good company to go long on for a three year timeline. (They didn't listen, I was only 17 and had never invested in my life).

It might be time to give them another examination.

LeftHandPath··on Tesla Q3 Financial Results
This is why you just go to the [EDGAR files](https://www.sec.gov/edgar.shtml) and think on your own.

If you want entertainment, read the interpretation given by a news organization with your preferred bias.

If you want real insight, read articles with conflicting agendas. I suggest Barrons and WSJ as the obvious conservative-agenda choices, and Bloomberg and Financial Times as liberal-agenda choices.

LeftHandPath··on Why Garmin watches have become common in some segments of tactical aviation
They are functional, durable, and extremely common in my office of Learjet and King Air pilots. I agree with you on the battery life. Personally I'd rather have some world-timer, but I'm an asshole.
LeftHandPath··on “We have no reason to believe 5G is safe”
Funny things start to happy on online discussion boards when billions of dollars are at stake. Comments deserve as much skepticism as the headline.
LeftHandPath··on The most successful people are just the luckiest, a new computer model confirms
> Good conversation piece, everyone has an opinion on the subject, but the experiment is rubbish.

Agreed. The paper also seems to be promoting a view of wealth inequality that would support modern socialist policies.

The paper seems to be trying to scientifically support redistribution of welfare, without actually doing or saying anything, or posing the question directly.

Someone is warping the numbers to fit their agenda. Since it's a popular (and polarizing) agenda, of course everyone will have an opinion to chime in with.

LeftHandPath··on The most successful people are just the luckiest, a new computer model confirms
It all boils down to just how deterministic you're able to believe the universe is.

Is there a such thing as my own willpower that allows me to improve my position more than an equivalently-placed person would, or is the willpower to act to improve my own situation derived from the blind luck of where and when I was born?
