justifier··on Is There a Cryptocurrency Bubble? Just Ask Doge
But what I want to see is proponents of cryptocurrencies acknowledge that the value requires a specific outcome to a yet unproven problem in mathematics(o)

How many people bullish for andor excited by cryptocurrencies know that?

any answer to that would leave you wondering: what are the implications?

If the majority answer: of course I know it could all be found to be worthless tomorrow

Or even if the majority answers: wait, it could potentially be mathematically proven to be useless?

Both leave me wondering what the motivations are for those who are promoting it

justifier··on How the Minimum Wage Affects Restaurant Hygiene
This is apparently business owners failing to uphold state required hygienic processes.. which in and of themselves are perhaps too forgiving

But my experience working restaurants shows under paying employees incited a certain apathy in the workers causing lazy implementation of food handling standards

I'd argue more pay makes the workers appreciate their work more which would tangentially result in better hygiene

But for an owner to intentionally 'skimp' on hygiene practices due to 'reallocated profits' is ridiculous

Also the tone is ambiguous, is the intent is the paper that I am supposed to see these dubious correlations of stats and think, 'they were right.. raising the minimum was a bad idea'?

justifier··on A French wine trade war
another interesting element of the wine trade across the eu was the ~2009 ruling on how rose could be produced

when i was working for a wine and spirits shop on the upper east side a controversial ruling was proposed in the eu(o)

it stated that rose wine, which was becoming a popular wine in the newish 'priced to drink' wine market, could subvert the costly precision of rose production, wherein for example one has to remove the skins at just the right time, with a simpler method of just mixing red and whites together

french wine producers were among the leaders in lobbying against the proposal

it seems france won that battle(i)

justifier··on Winning the War on Error: Solving the Halting Problem and Curing Cancer [video]
Yeah, but this is about player death stead level completion

In the clip the level maker cleverly constructed a trap wherein the player gets stuck between two blocked doors which creates an infinite loop passing Mario back and forth

The game engine realises what is happening after the second pass and just kills Mario closing the loop

justifier··on Winning the War on Error: Solving the Halting Problem and Curing Cancer [video]
A fun recent example mitigating the halting problem came from an affectionate troll level(o) in mario maker

I'm unsure whether the underlying implementation uses approximation techniques, as the op suggests, or if Nintendo simply identified potential halting offenders and added a layer of checks to overcome the intractable issue

note: the clip is loud and includes the player yelling fuck; in case that offends.. that said, the whole level playthrough is a lot of fun

justifier··on Ask HN: How to eat and drink properly?
the same way i approach learning anything new

i try to break it down into first principles, then try to break those principles into components and start to familiarise myself with as much information as possible

it can help to apply arbitrary constraints to aide in reducing the initial barrier of entry

from there you can start to construct your own diet around your interests, your body, and your goals

one day i became obsessed with cinnamon and would put it on everything

once i ran out of the cinnamon i had i went out to get more and learned there are different kinds of cinnamon

from different places with different preparation practices that result in different flavors, of cinnamon

so i'd try one, then another, then another, and eventually i developed a preference, now i know what kind of cinnamon i like.. and why

there is a lot to consider in regards to food and diet, but that is mostly what attracts me to it

for the most part it is an unsolved problem, but there are many great theories and theorems in regard its practice

curiosity ensures development

justifier··on Why the feds took down one of Bitcoin’s largest exchanges
blockchain has what i call 'effective anonymity'

if you buy 'into' BTC in an anonymous manner and make purchases 'within' BTC the transactions are wholly traceable but the source is anonymous

anonymity is lost when moving 'out' of BTC 'into' other currencies that require, or have subsequent effect, of identifying the user

then how would a relativist, as you describe it, justify the forms inherent in this vegetable.. i mean, what's the 'culture' of vegetables?
justifier··on Fractal Food: Self-Similarity on the Supermarket Shelf (2005)
i'd tend to agree with this proposition, but i was asking because i wanted to have my views challenged

i rarely get an opportunity to debate the philosophy of mathematics and i was trying to use this article about this common found mathematical object whose form expresses that computation explicitly to open a dialogue in that capacity

with that in mind, what are you trying to say philosophically with your question?

from your question i am inferring.. perhaps incorrectly, feel free to correct me.. that you think all phenomena are computed

what are the philosophical consequence of such a view?

Realism is the correct philosophical view? Formalism? Some other?

justifier··on Fractal Food: Self-Similarity on the Supermarket Shelf (2005)
but this is more about definitions right?

culture 1 : 2+2=4

culture 2 : 2+2=5

translation between culture 1 and 2:

2==2

4==5

180==360

if you could agree on specific definitions: this is a triangle, this is interior, this is an angle, and this is a degree; you would be unable to come to opposing conditions on the sum of interior angles

justifier··on Fractal Food: Self-Similarity on the Supermarket Shelf (2005)
it was difficult to frame this question

because the philosophy of mathematics has so many branches with even more leaves i just went with the vague 'opposing' of one branch to cover as much ground as possible

in doing so i was moreso hoping to encourage others would define their own philosophical views on mathematics

i suppose if i was 'arguing against' anything it was more against a sort of mathematical formalism that states math only exists in the mind, or the axioms defined by human minds

if one can construct fractals and then encounter a plant like this it would seem validating to infer the mathematics being utilised by both the plant and the mathematician does indeed exist outside both

justifier··on Lifesaving advice from a black woman held at gunpoint by police
This articles bothers me

Both the individual's story and her message here

I am glad it is here to bring further attention to these issues and even how this specific event happened to this woman

Both the encounter and how the police later handled the 'investigation' are both disgusting and why serious reform is anything but a top priority for officers and politicians is completely revolting to me

But I wish the author was more clear on what she meant in saying 'prevent the next philando castile'

Was she going to prevent it by filing the complaint and removing that officer from the street or was she insisting she would help prevent more philandos by educating others in saying:

> My behavior is how everyone should act in those situations: comply, survive and complain later.

Because Castile did comply and was still murdered

This clip discusses how the definition of 'comply' changes with each high profile murder

https://youtu.be/aufMdURbitU

Trevor Noah and the writers of the daily show have been discussing the issues in a way that I think has been highlighting some of the problems very clearly, and with great respect and composure

This clip calls out the silence from a leading voice defending law abiding citizens' rights to carry firearms, especially in regard to doing so without fear of being murdered by the police for carrying a firearm

https://youtu.be/0IJSSBMLz6g?t=250s

And this video showcases the newly released dashcam footage of the philando murder

https://youtu.be/wqgz7kRGVxg

We need to talk about these issues but insinuating blame on the victim is the wrong way to do it

I hope the article was actually focused on the prevention method of filing complaints but I wish that was more clear

So please, until this is solved, comply like Castile did and if you live to tell your side of the encounter then please report these offenders

justifier··on Life
typically i'd ignore semantic arguments but since this is in reference to philosophical consideration i'll assume you are someone who actually enjoys getting into the weeds of semantics.. if i am wrong in that assumption please feel free to ignore the superfluous following

your definition loses your purported binary classification when examined through rigor

> (a) it makes copies of itself

what about those forms of life that are unable to procreate, or choose to abstain? also 'copies' is ambiguous: see (b);

> (b) the copies inherit traits from the original

seems an unecessary condition.. if one is to accept the first than this is redundant, also it is confusing because you say 'inherit traits' and 'copies', a copy should inherit all traits, so which are we talking about? copies or trait inheriting progeny? if 'copies' is intentional what about forms of life unable to make exact copies of itself, like humanity?

> (c) the traits are subject to variation/mutation

if 'variation/mutation' is random one possibility would need to be completely foregoing the 'variation/mutation'

if 'variation/mutation' is deterministic then are there deterministic models of 'variation/mutation' that you would leave out of your definition for life?

(d) the success of the copies at making further copies depends on those traits which are inherited, then evolution must occur

what about life that fails in its own ability to continue to evolve but heavily affords other life to evolve further.. i'm thinking something like wheat that is scientifically controlled in its evolution because we forced its evolution to a sweet spot that for years helped humanity to evolve as we wanted

justifier··on Why Some Men Don't Work: Video Games Have Gotten Really Good
philz coffee, for real.. i've talked about it elsewhere on this forum

that was the most insane interview process that i have ever seen.. at least in regards to the asymmetry between interview process and the work being hired for.. i joked that i was expecting at one point to be asked to draw up a linked list on a whiteboard, or what is the worst case execution of heapsort

'->' denotes 'if accepted'

email a resume-> fill out comprehensive online application with questions like 'what is your greatest achievement in life' -> vid conference interview -> in house interview to meet the hiring manager -> in house interview where you meet the manager you will be working under

minimum wage, and is even one of the least demanding jobs by cafe standards: philz is all pour over, and each employee is only ever responsible for four cups at a time..this is at least how it is designed, i'd be unsurprised if real employees are required to take on more work during a rush beyond what they were hired to do without any pay incentives to do so..

but really, do you honestly think that everything is fine with the way labor, especially on the low income end, is being treated?

there is a serious problem here that needs to be address instead of ignored by holding up accusations of hyperbole as more important to discuss

your response reads like a dismissal of the gp

there are important factors to consider in regard to your comment

regional: where do you live? where are these labor issues worse? rural? city? east, west, south, mid?

educational: how educated are you and your friends? are those being denied work well educated? primary and secondary school educated?

racial discrimination, gender discrimination, age discrimination, and on and on.. this is a very complex issue

but i'll address your comment being similarly dismissive: Everyone I know who wanted a minimum wage job got one without any experience, maybe I just know a lot of outliers though.

all of your friends working minimum wage jobs had 0 work experience? how old are you? 14?

justifier··on AI’s big leap to tiny devices opens world of possibilities
weight quantization is basically a short list of shortened values used as an index for a lookup table that represents the desired full values

if you have a 24bit value.. say, a 24bit color, that means you have ~16million.. 2^24==16777216.. possible colors

but if you only want to use 200 colors you can, instead of representing them as the full 24bit value, use an 8bit value.. 2^8==256>200.. and have those 8bits represent a value in an index that points to the desired full 24bit value

so you have to ask yourself.. what parameters of my neural net can be represented as an index? or, what parameters are of a quantity less than the parameter values' size?

wiki defines ann parameters as:

An ANN is typically defined by three types of parameters:

    The connection pattern between the different layers of neurons
    The weights of the connections, which are updated in the learning process.
    The activation function that converts a neuron's weighted input to its output activation.
here is a great paper that tries to answer this question for you in a way that highlights error resulting from quantization decisions(i)

justifier··on When Simple Wins: Power of 2 Load Balancing
What are your adversarial concerns?
justifier··on When Simple Wins: Power of 2 Load Balancing
if you are introducing a nonce why use a hash? with a performance reflective mutating nonce on the user id modulo works as is

if you are introducing monitoring on a per user precision why use modulo? with a per user scheduled monitoring moving users based on user ids works as is

maybe i was unclear in the above but i like the gp's simple solution.. especially because i personally have an affection for the modulo operator, but also because.. it only requires an operator that performs in a scale dependent finitely specific number of cycles and works as designed without any monitoring

the above was intended to bring attention to shortcomings and probable failures in an otherwise elegant attempt

the method is flawed but the direction is superb

justifier··on When Simple Wins: Power of 2 Load Balancing
though a clever way to be able to ignore the real problem eventually time will force you to revisit from base principles

user_id%numb_server may work early on when user activity and uptake are consistent,

but what happens when user activity becomes more complex: increase in users, some users abandoning the platform, others using it more; and that complexity lacks homogeneous distribution through this only concerned property: 'user id';

what if over time you gain more users but the majority of people who drop the platform have a user_id%numb_servers==2|11|13|17

in this case you would have some servers working hard while others sitting dormant

what is the real distribution of the relation between activity and user_id over time? asymptotic(o)? similar to the prime numbers(i)? a gaussian distribution(ii)? a benford distribution(iii)?

whichever future dada will show to be the best fit, most distributions show a strong trend toward eventual favoring of values

which i think implies, to ensure an even distribution of work across servers, the problem requires something with greater dimensionality than modulo on an immutable value that is defined serially
