I generally agree with you, but it's nice that in Rust you can use a for loop if it makes more sense. I mostly end up doing this when I want to reduce to multiple collections (put type a in here, type b in there) or call functions that return different types of errors.

The other time it's very useful is when translating algorithms specified in an imperative form. I translated a bunch of algorithms specified as for loops to elixir, and it was annoying to have an extra source of complexity when comparing the implementations for correctness.
Lately, I've been studying machine learning, from point zero, with a focus on time series analysis. Two months in already completed a course on Python and another book on Pandas, several hundreds of hours later in the fourth chapter in a book I paid for on deep learning and time series analysis they provided me with the most important information I needed: there is no evidence deep learning works better than traditional statistical analysis using classical methods like SARIMA and ETS. Sure, great, if an academic is interested in theory hopefully making a breakthrough, however, the rest of us who are interested in applied should stick with the classical methods.

I was going to write a lot here but I'll keep it short.

What I discovered is that everything I want to do can best be done in PostgreSQL. It's one thing to do data analysis in a Python notebook and another in an environment that works dynamically on a server. My first guess was to do the heavy lifting in Python with Numpy, Pandas, and machine learning and have the node server -- instead of Django and if I'm learning a new web framework it will be Phoenix -- execute the Python scripts through stdin / stdout. Since started I learned that I don't need machine learning and that I can do the calculations inside PostgreSQL sometimes orders of magnitude faster than in Python.

I'm using TimescaleDB which provides the postgresSQL time_bucket() function and with chunks should scale very well. First I tried to integrate it with Prisma in node, however, that proved to be far too difficult and convoluted. I reverted back to using TypeORM in node and it was extremely easy to run all the boilerplate code to initialize the TimescaleDB plugin inside of migrations which would probably be just as easy in another framework like Phoenix with Ecto. Sometimes I use SQL queries in a string literal and other times I use the query builder for more dynamic interaction with the database and to leverage some of TypeORM's other features beyond only being a connection manager.

What I discovered which interestingly someone yesterday shared a popular link to a blog post on the subject[0], for most of time series analysis, Pandas isn't required and perhaps not the fastest solution. Grokking window function was a little difficult until I found this lecture on YouTube, Postgres Window Magic[1]. Leveraging and understand window function in SQL is probably the most important skill to have.

I don't need Python and Pandas for time series analysis. I can using TimescaleDB and some increased knowledge of using PostgreSQL do time series analysis using all the same infrastructure I've been using for the past several years.

Every power source has accidents. Deaths per TWh for nuclear are comparable to wind and solar. Every form of fossil is much worse. Hydro beats everything for major disasters; Banqaio Dam killed 26,000 people immediately and many more in the aftermath.
Some may find 'unconditionally floored' unrealistic, but hackers have already been able to activate the parallel parking feature while a car is travelling forwards - jerking the steering wheel rapidly to the side.

If the hacker could detect speed and make the cars swerve when they've been at highway speed for X seconds, it would be pretty horrific.
It is a treadmill. Of course any pet or child playing around the running conveyor belt is at risk.

TechnoGym products are of such incredible high quality, that I thought I'd mention them.
This is a good provision, but they are going to have to aggressively promote new sources of nuclear power, if they are going to feed all the new Electric Vehicles coming online AND replace coal. Not just keeping old aging plants operating.
Hard to get a grip on exactly what proportion of tech leaders are consensus builders versus alpha tech bros, but there is a trope of the highly opinionated leaders who rules tyrant-like, for example Steve Jobs, Jeff Bezos, Bill Gates, Steve Ballmer.
I don't get why everyone thinks this is so bad. It's great and free publicity for the photographers. They are trading their time for something that will bring them future business and will get them attention to get paid jobs. While I don't do photography anymore I'd take this in a heartbeat. Clear win for the photographers. Note that TV has a history (game shows) of trading free products in exchange for media mention (and this is way better than that).
My major beef with nuclear is the water impact [1], not waste fuel - latter of which we have good solutions to. Not to mention exclusion zones.

If all Nuclear had desalination, it still wouldn't offset it's waste heat capture problem which ruins downstream ecologies.

Can you persist Arrow-format data to disk? I see a lot of interests in it, but I can't figure out the use cases. For example, let's say I have ton (xx TB) of well-structured objects on S3. I want to run query via Spark/Presto on the data. I still need to deserialize the data from ORC/PARQUET into ARROW right? The advantage with ARROW here is if Spark/Presto can use this format to pass the data between worker nodes, the query would be faster because we don't need to deserialize/serialize when passing data between nodes? If yes, how do I utilize the format in Spark/Presto?
> > * Even though most of their code licensed under Apache license, some code is under their proprietary license.

> I don't really think this is a perfectly fair characterization. Their proprietary license is essentially "don't host a cloud database and charge for it" to stop Amazon from building TimescaleDB right into RDS, or similar.

"yeah, go ahead, infringe that copyright and host a internal/for-direct-clients only database, because i guess that would be OK from their license, even though it is not explicitly allowed"

pardon the sarcasm, but i literally heard that from our lawyers today regarding another project's license, as something (quoting again) "no lawyer would ever say to their clients".
As I understand it, Arrow is about the data format, to best optimize query capabilities in any language.

Think, “CapnProto” or “Protobufs” but for querying data rather than only data transfer.

In theory Arrow will enable users to “trivially” create high performance SQLite type querying in any programming language. Arrow doesn’t help with any other features of SQLite tho.

Maybe one day Arrow will also target on-disc analytics/persistence but for now it delegates to Parquet.
Popular Mechanics says the Ford Pinto was no more dangerous than competitors' cars: https://www.popularmechanics.com/cars/a6700/top-automotive-e...

Does anyone have any thoughts on that? I imagine that small cars are the most dangerous to be in, since they will stop more abruptly if they hit something, as opposed to something like a bus which will demolish almost anything in its way.
To be honest what is going on I feel more like is devs are blaming users for their error.

Their newest DLC release has 7% approval rating on Steam, it breaks savegames, crash a lot, and breaks features of past DLCs unless you purchase the new DLC, some users are livid and calling it "theft" or "extortion" because stuff they paid for was taken away unless they pay even more.
Yeah, theoretically. But because of remaining cultural / social mores, women in general probably tend to be less polygamous than male "players" are. So in practice, "polygamy" turns out to be one man having many women much more than the other way around. Therefore a few "Chads" remove disproportionately many women from "the market", and you get many more male incels than female ones.

Content moderation is incredibly complex. It's also very expensive to operate. If you're not managing it yourself, you're managing the managers and then you still have issues. When there is an onslaught like this, you have no means to moderate against the storm except to restrict posting or in this case shut down.
I remember meeting the TimescaleDB crew back at IoT World 2018. They were a wonderful bunch and took the time to explain to me the technicals behind their fork of PostgreSQL (TimescaleDB).

I'm very glad to see that they have carried themselves far, and I am excited for what's next for the company. Congrats!
I want to ask an honest question. Why can't they just let associates put people in time out? If you're put in time out once, it lasts for a few days, and the time doubles on each subsequent ejection. That'd solve the problem in a few days. Why can't this be done? Or why wouldn't it solve the problem? I must be wrong about how simple this would be.
So retrofit the existing coal power plants into being new nuclear power plants.

The current systmt is really distorted. Coal from Germany/Australia/US is taxed differently to coal from China/Indonesia. Products made from brown coal energy in China are untaxed. Chinese steel production using coal from Australia results in Australia having a carbon debt, but not China. If a ship is made with Chinese steel, no tax. Made with American/EU steel? Taxes.

If a ship burns the filthiest high sulphur bunker oil then it pays no more tax than a sail boat.

We can't fix climate change with exceptions for everyone.
Why would you assume they're desperate?

If I took a gig like this, I'd be damn sure that:

1) I am included in the rolling credits,

2) I have several cameo shots within the show,

3) I can use thumbnails of my appearances within my own web site and

4) that I am able to use the show's logo and likeness to promote my own business.

My site would lead off with :

"Award winning photographer. You may have seen my work recently on the hit Netflix show, 'Love Is Blind'".

Website switcheroo: links opening in tabs are dangerous (Tab Nabbing)
People who think this is predatory have clearly NOT worked in the TV / Film industry. Doing shit jobs for free in the hopes of getting some cred is the norm.
Not right but not news.

BTW just because it's going to be on Netflix doesn't mean Netflix is the employer. Netflix just buys the content. The staffing / contract decisions are made by the production company.
That only makes this vector more of a threat, not less.
The promotional aspects could be worth much more than whatever money they'd earn.
If you could provide the hypothetical Rust code you're referring to, that would probably make your question more clear here. I know both Rust and Go rather well, and I'm confused about which direction you're wanting to take the code.
They might get a few in fact. Probably a bunch of desperate wedding photographers after the pandemic needing to kickstart their business again.

The question is, will they get multiple people on the shoot for free, and will that get them better pictures than one paid pro?

Can you imagine doing the work for free only to find out you're competing with other photographers on the same shoot to get the best shots that they will want to publish so you can get your "exposure payment".
Tour de Peloton: Exposed User Data
L4Linux is just the usual Linux paravirtualized on top of one the L4 microkernels. We previously ran two instances of it on top of L4/Fiasco

The problem with that is that you don't actually get that much benefits from the underlying microkernel. Linux is just the same old monolith, just better isolated from the other resources not exposed to this particular (para)virtualized kernel instance, so you end up isolating more or less complete systems from each other rather than getting the normal benefits of capability based microkernel architecture inside a single system.

Now that's not nothing of course, but not usually what people are after when they're hoping for a usable, modern microkernel system.
Understood!

Don't want this to come across as overly defensive, but was under PR review for 3+ years by Influx with little progress (first submitted in November 2017) and during that period I think we did something like 2 significant rewrites. Became a bit of a moving target against telegraf that became harder to prioritize.
My wife has done professional wedding photography, and each gig is definitely a lot of work. Especially the post-event editing.

But high-end weddings can be very lucrative. If a wedding photographer is (a) ready to perform this level of work, and (b) can afford to do 5 unpaid gigs, and (c) aspires to break into high-end work, I can see this making business sense.

remeber that you are in a unique position where you know the ML application and specialized pSQL to implement it.

The market is paying big bucks for people that have either of those skills. If you are making less than 300k/y (at the very least), move out now ;)
Disgusting power play.

I will cancel my account with them if they don't provide free chicken wings every weekend for their free coverage in living room. Going to write to support now.
Of course. Photography is one of the lowest paid professions so of course you’ll have people tripping over themselves over the opportunity. Question is should Netflix who are flush with cash be a participant to this Gladiatorial Theater?

This is kind of grotesque coming from a company with very deep pockets.

This wasnt his first mistake, this was the one that finally pushed things past acceptable comfort for other decision makers. Founder/ceo of a startup is high risk, high reward and he lost on his gamble. It happens all the time. The company will continue without him.
Generally I agree - no ad-hominem or insults should be rule number one.

> Calling someone or a policy racist would fall under insults.

How can a policy be insulted? Policies are not people. I don’t see how calling a policy racist falls under ad-hominem.
make your money work for you, don't do internships for $0... even the YC plan is not that good... you get a few thousands to loose a big part of your company? Sometime it makes me want to start a YC alternative ;)
Fully agreed! I think the existing options for pre-made decks often resemble your "1000 German words" example, and the space of providing good pre-made decks is explored far too little and dismissed too quickly in the Anki community.

I can see something like Orbit very likely existing in the set of my future learning tools. Most texts that I read (doesn't matter with how much concentration), flow right through me and nothing sticks. The only way to make them stick is by exercising with spaced repetition flashcards, but creating them often takes so much time that I only bother to do it for the most important subjects.

A possible future evolution of the concept where cards unlocked on two independent websites can unlock further cards like "how does concept A (from website A) relate to concept B (from website B)" would be amazing, and seems very much in the realm of possiblity.
Sure, https://github.com/dtube/avalon - It's quite possibly the easiest blockchain to understand. The node is written in Javascript and uses a local Mongodb to handle storage of blocks and content data.
So what? Let the market decide. Or would you rather dictate what consenting adults can agree to because you are so much wiser?

Working from home has changed my life for the better.

I am so much more free to accomplish the things that need to be done in any part of my life. Whether that's writing code, doing the laundry, or finishing a side project. Everything happens when it is the optimal time for it (apart from the few mandatory team meetings)

I hope every company continues to relax their WFH rules because it is so much better for so many people.
I'm hardly saying it's impossible; I'm saying that it's not easy, and may even be hard. Doing it well would likely require a wide-reaching effort the likes of which would eventually reach my ears, and the fact that I haven't heard of such a thing implies to me that it's probably not an AWS priority.

Why that would be, I leave to you.
> They probably will find photographers doing this for the promotion effect described in the email.

Almost no couple will care - unless what they produce for Love is Blind is extremely out of the ordinary - but then they won't be able to afford it. There's a very good chance the photographers will get no new business because of this.
That would have been fine had they asked a young inexperienced photographer with cheaper and less gear. But they asked an established photographer.
No, I'm shooting from the hip and exaggerating (slightly). When you're sending an emoji for the first time, an app typically presents you with a selection of skin colors for the hand or face icon you're choosing. My point is that this is a design decision to impart significance into racial self-identity.

So the entire exercise is tautological -- of course people pick a skin color, when you frame the choice as "pick your skin color before you send this (or don't and we'll just keep using the inhuman color, which might communicate its own signal, or just look weird when everyone else has a skin tone)". And of course it's meant to be informed by race.

We decided to present skin tone (race) as something important, and people responded as though it's important, is not a surprising finding.
Because exploiting people is wrong.
Only to some degree, if Netflix is in some sort of executive production role on this project, then they likely have the pull to squash these kinds of requests.
IDSL was the first "high speed" connection I ever had at home. What a dream it was compared to dialup! Always on and 3-4x faster than the best dialup connection could do.
That's quite a bit more sane than their stance a mere week ago (everyone, back to the office, or else). I guess there were enough protests to be heard. Cool!
Do you believe taking a psychotropic drug for the very first time before a big pitch--before having any sense of what a proper dose might be--is on the the reasonable side of the spectrum between "risky" and "reckless"?
>I think unpaid internships being socially acceptable is one of the roots of this insidious habit.

When I worked with interns they were all paid... but every one was more time and expense to work with than any value they provided. In weeks they accomplished what I could do in an afternoon, and we spent WAY more than an afternoon of work with them. Amazingly many seemed to have a very high opinion of their productivity.

Now that's fine because when I did work with them the intent was to give these folks an opportunity / experience.

But I don't know about this idea that interns are somehow a gateway to getting value out of people for free. Interns in my experience (outside of maybe a unicorn out there) are not something you can expect to get much of anything out of.

I can't imagine coming out of the intern experiences I've had thinking that I'm going to get anything like worthwhile free labor from them.
There could be many reasons for silence, such as not wanting to be bullied into saying something, no matter how true it is. In some situations, that might be the nobler option and could take a lot of courage.
Nah, is always the people in comments, go to most movie.TV series reddit and see tons of comments that are like "bad writing, it should have been exactly like I want" (Because some random dude is better then actual writers with experience and awards).

Though thee is hope, I know that there is a fix, from my experience good moderation where rules like "no personal attacks" , "no lazy comments" , "properly explained critics" and a community that mostly reports bad behavior resulted in a good experience for me.
How would you quantify the harm to a consumer for this (or any other) specific data breach?

We won't see this meaningfully acted upon until that can be fairly quantified.

For context, research the "value of human life" in the legal system. The numbers vary widely, but its often seen as somewhere between $1m-$10m USD. Is data about your workout routine worth 1% of your "enterprise value" (your life value)? Probably not. 0.0001%? Maybe, that would be $500 @ $5m "life value".

But then again 70% of the $500 you are "owed" goes to the lawyers who facilitate the class action suit to get the money from the company, so enjoy a meager $150 :)
If they are compensated by Facebook, and if their positions require reappointment, then they are not independent of the company.
I don't know anyone during my time as a student that took an unpaid internship. How common is this? All the internships and jobs my classmates and friends were getting involved an exchange of money for goods/services. Who is taking an unpaid internship and why?

edit: I'm not sure why I'm being downvoted for not having been exposed to this. If you're willing to take an unpaid internship it's your own fault.
‘The Irregulars’ – Season 2 of the Show Has Been Cancelled by Netflix
The Irregulars- Netflix series was meant to get a second outing but it seems that the performance has not allowed the series to move forward. Reports from Netflix claim that Season 2 of The Irregulars has been cancelled.
Thanks, I have several Chinese/Asia news sources from December however I was asking for a BBC reference as M2Ys4U mentioned it was reported by the BBC on New Years Eve and the earliest I have is January 3rd.
Imho, if we want to move forward as a species into something like the "next level" of civilization, we need to pour trillions of dollars of effort into building a full stack of nuclear energy.

University programs, technical schools, research labs, and a robust supply chain for plant construction and maintenance.

The energy density of nuclear fuel would have convinced any higher rational society to do this decades ago. There is no contest, not with solar, not with coal or NG. Pound for pound (including all of the cladding, reactor vessels, and everything else), nuclear plants produce just so much energy.
Yes, it works, and that's why it's dangerous because it lets a manager fall into bad habits of doing it again.

It makes the people doing the work pull out all the stops - beg vendors for support, drive to the customer site to witness the problem, and generally so whatever it takes.
I was wondering why I recognised your name - you're the main developer of ffsend. Thanks for all the work! I really hope you get more people interested in maintaining and developing Send.
