lytefm··on Life is a game, this is your strategy guide (2014)
True, I was surprised [1] how many offended, negative comments this article got.

I automatically read it with a bit of tongue-in-cheek but with some valid points, not as "this is the ultimate life advice".

[1] well not really. Times truly have changed.

lytefm··on Life is a game, this is your strategy guide (2014)
Don't take everything in this article absolutely literal, then it's quite nice.

> A tired, irritable, unskilled player is not appealing, and probably shouldn’t be looking for a relationship.

It's obviously an exaggeration, but it has a fair point. Applies mainly to young men, less to young women though because they play quite a different dating game.

Working hard on becoming attractive rather than expecting to get interest from women "because you're such a nice person" isn't bad advice. Of course you should still try, but without expecting much.

> See how psychology just helped you become both rich and attractive?

It's even better. Learning just a bit about psychology, understanding yourself and others is also useful for:

- overcoming bad times and habits - helping yourself and others - feeling better overall - solving conflicts - making friends - figuring out what to do with your life

Psychology is probably the best meta-knowledge to have.

Didn't seem to me at all like "self grandeur", more like "here are some funny examples based on my background".

The overall game metaphor is quite nice and useful, also in relation to what the author writes about "fairness" [1].

Yes, these are great points.

> This habit loop has a cascading positive effect.

"The power of habit" is a great book on how to establish good habits. I no longer need willpower to do sports in the morning unless I'm completely trashed. Once something truly is a habit, it doesn't take willpower to do it anymore. It rather takes effort to deviate from it.

> This was a perspective that I could not see while I was in the situation, but as I've gained more critical distance, I've started to realize that lack of willpower was not the primary problem.

Taking a step back when finding a situation awful or feeling bad is also a helpful habit.

I wasted way too much jet fuel due to my own cognitive biases and emotions. Usually it's so much better to simply raise that issue with that friend, colleague or partner than to swallow things down and try to power through.

lytefm··on Personality variation eroded by simple social behaviors in collective foragers
What if the article has it backwards: I doubt that a random samples of same-aged people from a western and from a hunter gatherer society will end up with similar distributions of personality types.

I'd guess that some traits (e.g. being very individualistic, competitive or narcissistic) might only emerge in more settled societies where wealth can be built up and inherited.

At least Richard Rohr mentions this as anecdotal experience in his book about the Enneagram.

lytefm··on Deutschlandticket for regional bus and rail services to be offered for €49/month
> In my opinion it should be somewhere between dirt cheap and free if your income is in the bottom 10% of incomes (and could cost twice as much for the top 50%

True, for many people 49€/ month is still too expensive - e.g. low wage, low pension or living on welfare.

In its current form, it's mostly a relief for the middle class living in areas with good public transportation.

I'm definitely happy to pay just 49€ for all over Germany instead of 80€ just for Berlin. I'd be ready to pay more and think it would be fair if the amount was tied to the taxable income, like union memberships are.

lytefm··on Deutschlandticket for regional bus and rail services to be offered for €49/month
I guess it will have a small effect. There are more reasons for a „fake enrollment“ than just the ticket.

- child support money

- free public health insurance

- private insurance is often also related to „kids being in education“

Especially if the kid under 25 just wants to travel around, play fortnight at home or work on the next big thing.

My bachelor programme (maths + cs in a small German city) pretty much only exists due to that. Great student/tutor ratio because most only enroll for the student status (low fees, no public transport ticket).

lytefm··on Deutschlandticket for regional bus and rail services to be offered for €49/month
We still have massive subsidies for providing leased new cars, mostly selected from German car manufacturers, to employees (about 3 bn per year [1]).

Few people in the upper middle class and above will use public transport instead of their car, if it's provided by their employer.

The results from the 9€ Ticket also indicate that people aren't using their car that less often. They are just using the ticket to do additional journeys [2].

But I suppose that having this ticket available for longer than 3 months will motivate some households to get rid of/ not purchase a second car. Also, it will probably convince younger adults in metropolitan areas (like me) to not buy a car - or to delay it until it's needed for family reasons.

lytefm··on Identifying as an Artist
Jungian personality stereotypes never paint the whole picture, but are definitely useful as long as you don't see it as black and white.

Intuitive feelers ("artist types") often clash with observant thinkers ("engineer types") according to the theory and I've experienced this a lot, too.

lytefm··on PayPal Fees Are Insane
In addition to the points already mentioned (counterparty risk, currency conversion, popularity, ease of seller side integration), don't underestimate how much PayPal can increase conversion rates by making it easy for the buyer to make a purchase.

Fumbling around with credit cards or IBAN numbers + having your banking app fail randomly when trying to authorize payments is annoying. PayPal just works. Also, if you're some random shop on the internet many customers prefer to pay via PayPal rather providing you banking details or credit card numbers.

> That or give the option to accept the counter party risk for failure of transfers.

In Germany, merchants frequently offer to be paid by IBAN in advance or by invoice after the delivery. No fees, but the risk is fully on one side.

> And there surely is signing methods that one could do as an escrow like service to mitigate most of the fee.

PayPal basically acts like an escrow with their buyer protection policy. If you find another provider, good luck convincing the customers.

lytefm··on Most young men are single. Most young women are not
I suppose that the age similarity might mainly be a peer group effect. People in the early twenties tend to hang out a lot with people of around their same age, e.g. due to college/ university classes or parties. As long as dating happens predominantly within the peer group, age differences usually aren't very big. But once online dating is used, larger age differences occur quite naturally.
lytefm··on Most young men are single. Most young women are not
It is not surprising at all if we consider evolutionary psychology and how dating actually works due to the differences between men and women. David Buss did a lot of research in that field, this [1] is a nice intro.

Women and men have completely different attractiveness trajectories and „what's at risk” when having sex.

The article correctly argues that societal changes made it a lot more difficult for young men to find a romantic partner:

- No pressure to marry early in your twenties as a woman. Instead, it's even expected to „have some fun“ and marry later.

- Dating apps and a more individualistic society make it easy for women to find a mate outside of their social cirle.

Unless they've been doing exceptionally well (e.g. are physically fit, have a good status in their peer group, a well-rounded personality and make some money), men in their early twenties don't have a lot to offer to women of their age. On the other hand, women are usually in their peak attractiveness in early/mid twenties and can easily select an older partner.

Anecdotal experience also confirms that. I'm in my late 20s, my GF in her early twenties. She had no serious interest in anyone from her school year. We met on a dating app. Quite a few of my similar-aged friends who had very litte luck with women found a romantic partner once they've finished their degree and earned some money.

lytefm··on AI Becomes Silicon Valley’s Next Buzzy Bandwagon as Crypto Boom Fizzles
> I wonder if it will have to make a "BTC is a store of value a la gold"-esque marketing pivot too.

I think it's already happening. Fully autonomous cars or a Bing-like AI that is actually reliable are probably still decades away, if ever possible.

Instead, AI related companies are already pivoting towards enabling and assisting humans for specific use cases.

E.g. „We'll have LIDAR-based crash prevention and assisted driving in most new cars by 2030“ instead of „We'll have fully autonomous driving within the next years“ or „This AI based tool will reliably summarize key investor information from quarterly reports“ instead of „Ask this AI anything“.

lytefm··on AI Becomes Silicon Valley’s Next Buzzy Bandwagon as Crypto Boom Fizzles
> The main use case for crypto is creating ponzi schemes, skirting security laws, and other types of scams. The dotcom boom was not like this.

I'd say the dotcom boom was quite a bit like it:

- Completely overvalued companies without any real utility scamming investors claiming to revolutize X by doing it "on the internet".

- Evading regulation and breaking local laws, playing cat and mouse with law enforcement (e.g. Napster, Megaupload).

But yeah, unlike with crypto there were also more reasonable use cases.

lytefm··on Why dark matter feels like cheating (and why it isn’t)
I thought the same when reading the article. Dark matter doesn't just seem solid - it has even has mass :)

Dark energy is a whole different story and seems more like the epicycles of the heliocentric model: Adding a mathematical hack in order to fit the model into the data.

I'm remain curios about stationary universe model proposed by Peter Ostermann [1] which can explain the SNe-Ia data with homogeneously distributed dark matter and without a need for dark energy. Also, it is a lot more elegant and "Einsteinian" than the concordance model.

lytefm··on Open Assistant: Conversational AI for Everyone
I also think it would be amazing to have an open source model that can ingest my personal knowledge graph, calender and to do list.

Such an AI assistant would know me extremely well, keep my data private and help me with generating and processing thoughts and ideas

lytefm··on Show HN: Automatisch – Open source workflow automation, an alternative to Zapier
If it's obvious that the product won't get approved by risk management due do missing essential policies, I won't even take a glance at the actual product.

Automatisch would be interesting for me exactly due to:

> It allows you to store your data on your own servers, which is essential for businesses that handle sensitive user information and cannot risk sharing it with external cloud services. This is especially relevant for industries such as healthcare and finance, as well as for European companies that must comply with the General Data Protection Regulation (GDPR).

But automatisch.io doesn't include any data protection policies despite advertising a paid enterprise offering on their website and asking for data in a typeform. Also, there is only a copyright symbol without any link to a legal entity.

If it was just a non-profit open source package, I'd still look into it. But as it is, the website screams „don't touch this with a ten foot pole“ from a perspective of someone who is supposed to be the target group of your product ;)

lytefm··on How do you avoid missing the big picture at work?
> I think better terms than big picture people are ones that think abstractly, conceptually, or analytically. These are the folks who are good 'at naming things'. That means they understood both the business aspect of what areas to separate and iterate upon, as well as isolating technical factors that minimize code quantity and maximize flexibility. If they can do this with a minimal amount of abstract machinery/metaprogramming, that's golden.

This is what I aim for, too. Seems to be working fine for me. Some tips for OP:

- Try to get a lot of informal chats with relevant departments. Being in the office or at events s.t. you can join conversations + talk face to face helps.

- Be a „yes man“ whenever other departments have some technical issue that needs to addressed. Or even if it's nothing technical.

- Think more from a business perspective during technical planning and implementation. Does it really create value to code more than the most basic MVP here? Do we really need that fancy technology and scalability?

- Get good at communication and soft skill in general. If you're smart but „difficult to work with“, you'll end up doing mostly specialized work.

- Get good at note taking and knowledge management. Where was that link to the product roadmap that was shared two months again? What was the context for that design decision two years ago? It's useful if you're able to answer questions like this with your notes.

lytefm··on Ask HN: Strategies for working with engineers that are too smart?

lytefm··on Ask HN: Strategies for working with engineers that are too smart?
I agree. If an engineer comes fresh from university/ leet code/ certain companies and hasn't yet adopted the kind of mindset you're looking for, teach them!

If they are actually smart as in „intelligent, humble and curious“ they'll understand and adapt.

During my first two years as a developer, I was also in the „a double for-loop? Not under my watch!“ - camp and wrote a lot of „clever“ code that often was a waste of time or even caused problems lateron.

With experience + reading more about software engineering „in practise” as opposed to „in academic theory“, I learned to prefer solutions that don't use many layers of abstraction, are simple enough for a junior engineer to understand, easy to maintain and actually add value for the business.

A smart engineer knows that engineering time is limited and expensive - and acts accordingly.

lytefm··on Intermittent Fasting Completely Reverses Type 2 Diabetes in Study
I'm no authority either, but I've worked in the field of metabolic health for a couple of years and read a few dozen studies and books on the topic.

You're pretty much correct:

The most relevant contraindication for any kind of fasting are eating disorders like anorexia. Also, don't try out fasting if you're taking metabolism related medication without consulting with your doctor.

A lot of research suggests that most lifestyle diseases that are prevalent in the developed world (like obesity, diabetes, heart attack, even some types of cancer and possibly also neurodegenerative diseases like Alzheimers) can be prevented and sometimes treated with a dietary intervention.

The optimal diet seems to be whole foods and mostly plant-based (though some people seem to thrive on meat) with occasional fasting periods.

It makes a lot of sense from an evolutionary perspective: Our ancestors didn't have all that sugary and industrially processed food and often spend extended periods fasting and searching/hunting for food. Processed foods highjack our preference for calorie rich, sweet and savory food but are often deficient in nutrients.

VLCD is extremely difficult to do. I doubt that many people would be able to stick to it outside of a controlled setting.

IF on the other hand doesn't require you to eat less calories than your body requires. Skipping breakfast works pretty effortless on the long term.

I can confirm that black coffee usually works just fine when doing intermittent fasting.

There are also a few startups (in the US e.g. Levels, Veri) which offer more insights than just using the libre sensor „as it is“. Unless you already know a lot about metabolic health, I'd recommend going that route over just getting the sensor.
lytefm··on Intermittent Fasting Completely Reverses Type 2 Diabetes in Study
I very much doubt that most people in the western world who complain about being „hungy“ have ever experienced actually being hungry.

If you don't eat for about day (or longer), the short-term glucose storage will be depleted, ketosis starts and you'll actually feel hungry - though it usually fades once the body adapts to breaking down fat and proteins.

Having an empty, possibly even grumbling stomach or feeling appetite/ craving for sugar isn't hunger. I can recommend trying out to fast for a couple of days in order to experience the difference. I've kinda intuitively shifted to intermittent fasting afterwards and usually don't have any urge to eat food until after noon.

lytefm··on Ask HN: How do you work on your mental health?
- Journaling.

- Processing emotions via creative writing. I tend to write songs, others might prefer poems or stories.

- Learning a lot about psychology. No matter how weird your issues are, most likely you'll find some helpful resources online.

- Self acceptance and self-authoring. We tend to tell ourselves pretty dumb and limiting stories about ourselves.

- Guilt free play time. Not trying to always be productive.

- Setting and enforcing boundaries in private and professional life.

- Listening to music and podcasts that resonate with me.

And of course basics like proper sleep, food, exercise, relationships. I don't watch TV, I don't use social media. That probably helps, too.

lytefm··on I became a software engineer after 5 years in data science
My educational background is much closer to data science (Math with CompSci Minor B.Sc., Data Science M.Sc.) but I've never worked in a pure data science role.

Training and tweaking models looks like the easy part of developing data driven products. Hiring compenent enough people also seems easier than for software engineers.

Many ML libraries produce good enough results without having to design elobare models myself. I see data science more as yet another tool in the belt of a a software engineer - like server admin, CI/CD, IaC, databases,...

lytefm··on The plight of those who do not live under strict privacy laws
A GDPR request can be quite a challenge for any company that doesn't have fully automated processes in place.

I guess it's often not malice, but rather "we have no clue in which SaaS we might have your personal data, don't want to drop everything for a week in order to figure it out and simply hope that you won't sue us if we don't reply".

So if you want to screw over an early stage startup:

1. Buy their product, use everything on their website where you can leave your personal data (newsletter, chatboxes, send an email,...). Document the requests that are made. 2. Request your data according to GDPR. Preferably by mail. 3. Take a lawyer and sue them if you find any inconsistencies. 4. Rinse and repeat until they've either fully automated the process or are out of business.

lytefm··on What Is a Wildcard Person?
Well, my sample size is small (INFJ: me and a CTO at a different company, INTJ: two colleagues) and my MBTI knowledge based mainly on https://www.16personalities.com. I'd still say it can fit quite well because:

- Introversion: useful for working on the kind of technical tasks outlined in the article instead of preferring to work with other people (apart from the customer success example).

- iNtuitive: coming up with out of the box, ad-hoc ideas to solve whatever new challenge is there.

> When there’s a need for innovation or a different perspective, people with Intuitive personality types can usually step up and provide a new direction. Practicality can sometimes be overrated, especially when a situation calls for serious change and “coloring outside the lines.” [1]

- Feeling: Yeah here I agree that „Thinking” types would suit better according the core theory. But when put in contrast to INTJ, I think that's the dimension which can cause someone to become a wildcard in the first place instead of a specialist: wanting to help everyone else in the company rather than focusing on more clearly confined problems for a long time.

> morale killers for these personalities may include strict rules, formal structures, and routine tasks. They may find it especially dispiriting when they’re asked to redo their work, particularly if it’s for a reason that just doesn’t seem valid to them. [...] At times, efficiency may be less of a priority for Advocates than collaborating with and helping colleagues who need a boost. [2]

- Jugding: I agree that „Prospecting” suits better according to the theory.

So overall, INTP seems to be better suited by theory. But in practice, INFJs are also drawn to the wildcard role and can get quite good at it.

[Edit]: Re-reading the article, especially the „wildcards in summary“ part is a very close match with „infjs at work“ (unknown challenges over routines, importance of impact, creative and independent problem solvers)
