My wife and I adopted two older boys (10 and 12). Most of the families trying to adopt are looking for babies but we were looking for older kids. It still took almost 2 years to get our first kid placed with us because I think the social workers weren’t sure if my wife and I really knew what we were getting into. But once we got the first kid I think they realized we were good. Then a year later they called us out of the blue about a second kid.
There’s some really weird commons / arms race dynamics underlying Bitcoin.

A few thought experiments:

1. Suppose the large miners all collided to proportionally decrease their hash rate. The cost to mine would drop while they would still earn roughly the same amount of Bitcoin, as long as the large miners colluding still represent the vast majority of the network’s hash power.

This would make new entry cheaper and thus it’s likely to spur new competitors to enter, defeating the purpose.

But it seems like things are pointing toward a ceiling like that - where minimum hash to have even a chance of earning BTC is so high that there will be no more entrants, and at that point there’s no reason for the extant miners to increase their hash rate.

It seems like a real catch-22: the network design is meant to decentralize the ledger such that no one can control it, but the rapidly increasing cost of mining leads to consolidation and centralization of mining, which at some point becomes a major threat to the network.

2. Suppose Bitcoin were regulated (impossible in the real world) such that no one was allowed to mine at more than some low hash rate, and also in order to have a wallet it had to mine. Thus every holder of Bitcoin would be mining just a little and the hash power would be far more distributed.

As far as centralization goes, such a network would be more secure. But would the total hash power be as high, and therefore would the network be as secure against outside parties launching 51% attacks? Hard to guess.

I’m long on Bitcoin, but I do wonder where it’s going as mining becomes more and more expensive, and the majority of Bitcoin use is more like commodities trading than decentralized use as currency.
Academia is beginning to realize this problem. NYU for example offers subsidized apartments to faculty realizing that it would be almost impossible to afford an apartment near the campus on an assistant professor salary.

seafood is cheap af in greece.

When I was in Athens, a kilogram of fresh caught sardines ran about 2 euro for a kilo. Thats cheaper than canned!

On Crete, it was a bit more expensive at 4 euro per kilo but I never paid more than 4 euro for a pound of fish. thats cheap enough to make fresh caught fish a daily meal
True, but I'm not talking about simple users. I'm talking about companies extending Kubernetes or building adjacent software. Even if their service doesn't necessarily integrate with Kubernetes, there is frequently a temptation to "follow your heroes".

Look at the whole Cloud Native Foundation thing, I think most of their projects are developed using Go.

So if you're using that stack, it's easy to assume that all new development everywhere is in Go.

It will probably balance out once the newness wears off Go (I think this is already happening).
Yep. I also like to leave a paper trail for myself when I'm having a similar issue. I'll typically leave information like workarounds/patches or explain how I ended up there
Have you tried conversing with it, after a few lines of setting a proper context? Like two scientist talking or something like that. It can provide very interesting outputs that are not googlable.

Yes, every time you see something that for human obviously doesn't make sense it makes you dismiss it. You would look at that output differently though if you were talking with a child. Just like a child can miss some information making it say something ridiculous it may miss some patterns connections.

But have you ever observed carefully how we connect patterns and make sentences? Our highly sophisticated discussions and reasoning is just pattern matching. Then most prominent patterns ordered in time also known as consciousness.

Watch hackernews comments and look how after somebody used a rare adjective or cluster of words more commenters tend to use it without even paying conscious attention to that.

Long story short, give it a try and see what examples of what people already did with it even in it's limited form.

To me you are looking at an early computer and saying that it's not doing anything that a bunch of people with calculators couldn't do.

If you ask GPT-3 for three Lord of the Rings quotes it might give you two real ones and one fake one, because it doesn’t know what truth is and just wants to give you something plausible.

There are creative applications for bullshit, but something that cites its sources (so you can check) and doesn’t hallucinate things would be much more useful. Like a search engine.

Fish can also have lots of mercury that meat lacks. It's probably best to eat a variety of different foods in order to avoid excess toxins and nutrient deficiencies.
What the actual... why is this on the first page?
The bigger problem with this approach is that you can't remove/erase something from the list just by knowing it's address. This is a key mechanism for most use cases. However, if you're fine with limiting yourself to erasing only during iteration, it's pretty nifty.

I've also done some benchmarks in the past and found it interior iteration performance due to what I'm assuming to be inability to prefetch the next address. However, linked list iteration is already relatively slow so I suppose it's not a big downside.

Huh? I don’t watch porn because real men don’t. Not banning anything. Don’t promote human trafficking. I investigate federal prosecutors and sex traffickers. I’m the one who turned Peter Nygard into FBI in Feb 2006. He was finally arrested in Dec 2020.

> It was a deliberate choice Americans made as a society. In Bangladesh, we have strong norms in favor of marriage and strong taboos against divorce

The argument about shame based "norms" keeping people together aside, it was in many places, quite literally the law that forced women to stay with their husbands.

Up until the 70s and later, in many US states it was:

* Legal to rape your spouse

* Legal to restrict a woman's access to contraceptives

* Illegal for a woman to abort an unwanted pregnancy, even due to rape or incest (the previous two combined with the first essentially stripping a women's autonomy to decide when and how many children to have)

* Illegal for women to work in certain careers/legal to discriminate on whether a woman was pregnant or had children

* Legal to prevent a woman from opening a bank account or line of credit without their husband's consent

This was more the case in some places vs others, but talk to an older women in the US what the culture was like for women then. The women's liberation movement happened in reaction to severe oppression and we absolutely should not consider reverting to a society before then.

EDIT: Yikes. I was curious about the norms in Bangladesh. I don't think Bangladesh should be held as an example for anything related to marriage.

https://www.girlsnotbrides.org/child-marriage/bangladesh/

> 59% of girls in Bangladesh are married before their 18th birthday and 22% are married before the age of 15.

> Bangladesh has the third highest prevalence of child marriage in the world, and the second highest absolute number of women married or in a union before the age of 18 globally – 4,382,000.

> 4% of boys are married before the age of 18.
> consider that someone with millions of followers is basically planning acts of violence with a retweet

So by your standard, would https://twitter.com/rezaaslan/status/1307107507131875330 count as planning acts of violence, or would he need more followers first, since he's not at "millions" yet?
Maybe imaginary friends are a normal childhood thing... among children who grow up to write children's books.
I have been using pythran for the last year and the nice thing is that you hardly have to rewrite anything but get speeds which are often as fast (or sometimes faster) than c modules.

The problem with cython is that to really get the performance benefits your code looks almost like C.

I agree with you on the optimize the bits that matter, often the performance critical parts are very small fractions of the overall code base.
Searching for site: developer.mozilla.org "deprecated" should reveal some deprecated browser API's and JavaScript stuff. I think the Chrome team wait until less then two million sites use something before removing it. For example sync XHR is currently on the deprecation list and will be removed once the usage is low enough. If sync XHR is removed you can no longer sync load modules on the web.
interesting insight! thanks

Block sizes are under 1MB.

Anyone can rent a VPS for under $10 USD per month that would transfer that in 1/100th of a second.

The block time is 10 minutes.

Why do people repeat stuff like this? Is it because you have seen other people say it and never stopped to look at the math?

...disagree. If you click on the comments on the well known conservative personalities that Parler sends you by default as an "average user', it's all right there. There's no need to search.

Actually, most second amendment advocates believe that this is exactly what it means. They think that the whole point of the second amendment is to empower people to resist the government by physical force.
Scientific computing languages usually are base-1, such as Fortran and R. Python is a general purpose, so naturally it takes after C.
> Julia is a growing alternative to Fortran/C/etc for long-running computations, it remains awkward and unpleasant for interactive analysis

Did you mean to write short-running scripts? If anything, the Julia dev workflow is biased towards interactive analysis in a REPL a la R or IPython/Jupyter. I don't mean to imply that there's no startup overhead, but how often are you restarting the REPL when doing EDA? Unless it's more than once every few minutes (which is a very odd workflow), then startup overhead is effectively amortized.

> A real strength of R (in comparison not just to Julia but also to python) is that such a repository exists

CRAN is certainly a cut above many other package repos here, but I'm not sure "trust their tools" can apply to all packages on there. Anecdotally, I've had a lot of issues with compiled dependencies and missing/out of date external assets on less well-trodden packages. There's a reason MRAN, Conda and JuliaBinaryWrappers exist after all.

For whatever reason, Julia package maintainers also seem more receptive to making their work compatible with other libraries as well. This goes beyond just multiple dispatch as well--imagine if tidyverse/non-tidyverse wasn't such a hard split.
Ask HN: Has anyone tried to do strava for music practice?
I've recently started playing the violin and guitar again after ten years of ignoring music (because I was forced to play as a child). During that time I started two technology businesses, one successful and one not, and I've learnt an okay amount about the 'tech start up' space.

When I practice, I have no record of what I practice, when and for how long - unless I write it out into a spreadsheet or airtable (which is what I've been doing). Time consuming, not standardised and takes more effort the more I practice. Hard to record that I practiced from bar x to bar y. Difficult to manually compute whether I've got good practice coverage over a whole piece.

Does anyone know of anything that works like Strava, can passively 'listen' to my practice and produce a sense of what I played and for how long. Produce 'snippets' of sound from each day so I can compare day to day (I do this manually right now).

I'm trying to work out whether this is something I could pursue as a start up (and scratch this bloody itch). Thanks!
>My main point of friction with jupyter notebooks is the stupid json ipynb format. Why can't it be just a regular language file with comments?

Have you ever used Jupyter notebooks? They contain code, rendered Markdown, images, plots, video players, widgets, etc.

How do you see a "regular language file with comments" supporting this, instead of the "stupid ipynb format"?

You can use plain text files with Jupyter, too.

Makes me think of having a single issue on a github repo for feature requests and anyone can dogpile onto it. If anyone opens a new issue with a feature request you direct to the other "feature request issue" and close their new issue.

Keeps issue bloat under control and allows users to request features in the same place as the code.

Base-1 makes sense in sciences where you've Fortran, MATLAB, R, Mathematica. If anything before Python's rise in popularity base-0 was the strange choice. Fortunately you can use arbitrary indices with OffsetArrays.
It's simple: waste. Everywhere.

There is no incentive for doctors to be efficient so they aren't. They order too many supplies, do too many procedures quickly (when doing them slowly would be fine, and cheaper, etc).

Price discipline is like gravity. It affects everything. In most American businesses subject to market forces, there is an enormous push to optimize every single little bit of the business to control costs.

This force simply doesn't exist in healthcare.
It was an egregious mistake and PR disaster. It wouldn't be fair to fire some mid-level HR manager over it.

The head of HR should be held responsible for her department, and she was.

A counter-example is the VW emissions cheating scandal, where the execs blamed and fired mid-level engineers. If a company gives orders, people who give the orders are culpable, not the people who receive them.
It's important to note that Vietnam, much like China, only promises the mixed economy temporarily, and officially at least claim that they will move away from it once the country is sufficiently developped.

Isaac Asimov: What Is Intelligence, Anyway?
https://www.backblaze.com/blog/reed-solomon/

In particular, these two images:

* https://www.backblaze.com/blog/wp-content/uploads/2015/06/bl...

* https://www.backblaze.com/blog/wp-content/uploads/2015/06/RS...

Note: Backblaze here uses "vertical data" (G * data) instead of what I did earlier "horizontal data" in the form of (data*G). But otherwise, still a good blogpost.

------------

So if you have 5 data + 1 parity, you now have a 5x6 generator matrix, giving you one extra column for erasures.

If one column is erased, you replace the erased column with the parity column, creating a 5x5 matrix.

As long as all columns were linearly independent, the resulting 5x5 matrix remains invertable.

The specific matrix multiplications / inversions / operations are well documented in that blogpost.

-----------

EDIT: Erasure decoding is much easier than error decoding. Error decoding requires figuring out the "locator", and then applying the calculated errors at those locations. Since we already know the locations in an "erasure" situation, we can just manipulate the matrix in an obvious manner.

--------

EDIT2: Ah right, the "systematic form" of the Vandemonde-Reed Solomon construction is to perform Gaussian Elimination on the non-systematic matrix (with the goal of forming an identity-sub-matrix). After gaussian elimination, the "column of ones" (or the simple XOR) disappears. (Erm... row of ones in the Backblaze pictures)

So maybe the Golay code you're thinking of is a better example as a matrix with an explicit parity bit.
I have a checklist for frontend dev that I run through before submitting PRs - https://gist.github.com/onion2k/8615d92178f9d1eb2d162da69495... - it doesn't improve the quality of a feature but it stops my PRs being returned for silly problems. I can highly recommend writing your own.
My point is that with New Shepard they have an intention to be something commercial. As I said, I'm unsure about this market.

That's why I don't let black people into my restaurant. Statistically, they're more likely to commit a crime once inside, so I don't want to take the risk.
All the black people in town end up going to the restaurant down the street, who had their register robbed one time by a dark-skinned fellow that I turned away because he sure looked suspicious! I sure hope they've learned their lesson by now.

You can bet that as a black person in our town, you'll pay substantially more than white folks, because most of us understand that black people have a reputation for this sort of stuff and general trouble, and we don't want to take the risk.

I really wish there was some kind of certificate to let us know which ones are the docile blacks...

Yes, I made it. The primary goal was to learn how to make a real-site that can also scale.
Yes, there were a few interesting problems, especially how to make it support a large load; the solution has been to use socket.io and Redis. I'm thinking about writing a blog post about it.
I'm validating all usernames, for now I don't have problems caused by ASCII characters.
For now the website is supporting well the loads. client and server communicate via websockets (using socket.io), and this drastically reduce requests. Moreover, I'm using NGINX as a load balancer to further improved the load support.
That's one thing missing from BASIC in other programming languages, the SWAP statement: SWAP x y

I lost my sense of taste for about a week last year (Not Covid related, apparently). I was honestly hoping it was gone forever. I've never eaten so healthily in my life. It's really easy to not eat garbage when everything tastes the same anyways. The sadness of not being able to taste cheeseburgers again was completely offset by the lack of desire to eat cheeseburgers anymore. If anything, the biggest issue is that b/c eating felt like a chore, the first few days I grossly under-ate (< 1000 calories).

Strangely enough I could still smell, and as the author points out, smell is an important danger indicator, so I would definitely be more frustrated losing that.
It's a bit late to reply, but I do think that would be a win, if not as great a win as using the money elsewhere.
