LambdaTrain··on Making friends on the internet
I do not think this is a terrible idea. Games such as league of legends feel dramatically different when I play with friends in real life.

One strange thing is that as my age grows my preference for multiplayer game changes from "competitive" to "coop".

LambdaTrain··on IQ Test Made by Mensa Norway
I would take it if demon offers me a a deal that transfers my pattern matching IQ to the proficiency of using language as a tool (in Wittgenstein's sense)
LambdaTrain··on Former eBay executive in pig mask case pleads guilty to stalking, tampering
Link to gov release: https://www.justice.gov/usao-ma/pr/former-ebay-executive-ple...

"Senior executives at eBay were frustrated with the newsletter’s tone and content, and with the tone and content of comments posted beneath the newsletter’s articles. The harassment campaign arose from communications between those executives and Baugh, who was eBay’s senior security employee."

Now what about these frustrated "senior executives". This is mafia in age of internet. Cringe.

LambdaTrain··on The silenced deaths of the Shanghai 2022 lockdown
One of my family member is living Shanghai who has not taken any vaccine yet due to contraindications. Not to mention that there are millions of elders living in China who are not suitable for taking vaccine.

I am very concerned if an authoritative gov aiming for "zero-covid" would push and mandate every citizen to be vaccinated. But I saw all these comments bashing gov on "why lockdown", "why not just take vax", "why not herd immunity" without deeping into questions - which is not much different from "Let them eat cake”.

LambdaTrain··on The silenced deaths of the Shanghai 2022 lockdown
Or by Occam's razor, I would say the goverment simply screws up (so badly) at their top-down approach at this stage.
LambdaTrain··on Primer: Statistical Armour
Multiplying the saved cost by probability of a defeat (which is ineffective mentioned by writer) does not seem bad considering the grid is low-cost design.

But placing timer/accelerator in RPG as a backup plan for fusing in case the warhead is shortcircuited also seems low-cost. I must be missing something here.

LambdaTrain··on The endgames of bad faith communication
I am not familiar with public debate. Before two persons start a public debate, is it a common assumption that you are going to hold your ground till the end, whatever the information provided by the opponent?

There is no flow of information and I could not see this form of acts as "communication" - it seems to be more like a kind of art/show/performance.

LambdaTrain··on The endgames of bad faith communication
It goes far beyond twitter culture. Even in daily conversation there are people who only open out port and close in port. One signal is that whenever you bring up a perspective (either in support/disagreement) this person gonna continue his speech and make the conversation expereince like attending a lecture.
LambdaTrain··on Understanding Strategic Culture Through Games
"Implicit learning is “nonepisodic learning of complex information in an incidental manner, without awareness of what has been learned.”

If I am terrible at online competitive games, does it reflect my poor implicit learning ability on strategy?

LambdaTrain··on Swapping two Numbers without Temporary Variables
the second half my comment is wrong. As someone comment points out there is xor swap
LambdaTrain··on Swapping two Numbers without Temporary Variables
To deal with overflow the size of variable a needs to be doubled. This trick, if applied correctly, uses the same amounts of memory.

Now you may wonder whether we can mathematically prove swapping two variavles requires memory of three variables in digital computer...

LambdaTrain··on Words known better by males than females, and vice versa
As someone who is not a native-English speaker, it is interesting to see a couple of familiar words in male category such as katana, yakuza, azimuth, etc. Probably due to my gaming hobbies...

And none of words in female category ring a bell to me, which is not surprising since I do not even recognize most of them in my native language.

LambdaTrain··on Ask HN: Hacker claimed ownership and then deleted my Facebook Page of 50k users
Not a response as a solution to Op: is there any recommended open-source project that can be used to self-host a comminity server?

I would expect that as a host I just need to focus on configuring and maintaining instead of learning to build a website, for example, it sounds like hosting vpn using Wireguard.

On the other hand, I wonder if that really makes it better off than to use fb/discord, since if fb/discord is vulnerable to hack, so is my own hosted one.

LambdaTrain··on Agatha Christie could afford a maid and a nanny but not a car
Your examples are more like colleges charging more tuition on out-of-state student, or tourist attractions charge lower price to locals, which are made public information. The context under this thread is talking about dual price that is deliberately taking advantage of information asymmetry, differentiation, or even discrimination based on social class and skin color.
LambdaTrain··on Reasons I'm Still Blogging About CRPGs After 10 Years (2019)
> Prior to 2010, my CRPG addiction was a solitary, lonely, shameful experience.

Exactly feel for this part. I do not let people know that I play games (rpg, online competitive, etc) as a hobby, except for few friends I have known since school.

It is a mental image in which playing video game is not socially acceptable for a young male in United States. But I do not think it really matters - instead of impressing other people, having a hobby is to create room for myself.

LambdaTrain··on A simple math equation can transform your productivity
Right. It feels like Op uses wrong math but gets a good conclusion in the context of doing daily job: focus on one shit.

However, in general sense, the return of an investment is considered as random variable, so the problem is not just max value, but max value while minimizing risk, and the solution is multitask/portfolio

LambdaTrain··on Emergent Behavior in Skyrim's Fox AI
Just want to make sure if I correctly understand what it means by "triangle": For navigation, the developer triangularize the skyrim world, and these divided triangles are not the same size - for example, a 100-sq feet field is covered by one triangle, while a 100-sq feet point of interest is more complicated and covered by more triangles. The original design intention is that the number of triangles encodes the sense of distance, but maximizing the #triangles actually leads to interesting places.
LambdaTrain··on Ubisoft deleted account with hundreds of dollars’ worth of games for inactivity
Inacitivity of a digital content account is usually a consequence of my indifference to that content & provider, which also means that I do not care about that account anymore.
LambdaTrain··on Hacker steals Sydney man's life savings after simjacking
Can we consider being hacked as something like traffic accident or injury? People are trying to make systems more secure, but if we think of the small but inevitable probability of being hacked, can we build an insurance product around it? On the provider's perspective, it is not easy to verify the insuree is indeed hacked though.
LambdaTrain··on I found that college fails to live up to being “The Great Equalizer”
I was wondering if the question is really about the gap between education and job requirement rather than the mismatch between graduate supply v.s. position demand. The gap one is certainly an important question, but it would not be surprising that most of CS graduates does not get a job relevant to their background if "the colleges supply 1000 while the open position is 100 or less".

With regard to the context of the article, the example that Uber driver gets a degree in acturial science does not tell much. Probably he is just doing worse than other graduates - even though he is qualified for an acturial job, the employer has tons of better candidates.

LambdaTrain··on Lithuania evacuates its embassy in China
He completed BE in Chemical Engineering from Tsinghua University [1].

LambdaTrain··on TikTok streaming software is an illegal fork of OBS
A lot of companies do not hire software engineers to implement the system; instead, they contract it to third party (tech service companies such as Cognizant). I think some sort of auditing is done at the delivery, if they concern about the license. But in the context of Java web app, the enterprise software is usually built on dependencies under APA, so it should be of less concern
LambdaTrain··on Tell HN: AWS appears to be down again
That sounds like the setup of Asimov's Foundation series
LambdaTrain··on Tacit knowledge is more important than deliberate practice
I like how Op introduces Naturalistic Decision Making (NDM) to address the question about how to accelerate expertise. But I am just a little critical/suspicious about this narrative, because Op and those NDM experts such as Gary Klein are working for companies that monetize this method. Is there any real world evidence that can soothe this sense of suspicion?
LambdaTrain··on Common Jobs in a Medieval City
Just visualized this Montpellier as Oxenfurt in witcher 3
LambdaTrain··on Secrets of The Great Families
The genetic impact of a talented ancestor diminishes rapidly after generations (say multiply 80% several times it quickly turns small) if no other factors comes into play.
LambdaTrain··on ProctorU is dystopian spyware
The fact that a linux security course uses proctoru for exam is the entire sarcastic point.
LambdaTrain··on How to build a universe that doesn’t fall apart two days later (1978)
edit: well...maybe the intrigue part of this article is that I, as a reader, cannot tell the context - whether it is fiction or essay?
LambdaTrain··on How to build a universe that doesn’t fall apart two days later (1978)
I feel like being lost halfway when the essay went into Christianity and established connections between Bible and his fictions and realities. It does not make much sense to me, probably because the examples and coincidences he refereed to were so "tiny" and insufficient to support his view.

I guess if the reader had experienced similar amamnesis as of the author, these ideas would strongly appeal to them then.

LambdaTrain··on Why Mathematics is Boring (2007) [pdf]
I think many people who start finding mathematics interesting at an older age and blame the math education in young age missed that their intellectual capability also strengthen with their age. The whole point of something being "interesting" is that this thing is possible to be understood but not that easily.
