  • and my point was explaining that that work has likely been done because the paper I linked was 20 years old and they talk about the deep connection between “similarity” and “compresses well”. I bet if you read the paper, you’d see exactly why I chose to share it-- particularly the equations that define NID and NCD.

    The difference between “seeing how well similar images compress” and figuring out “which of these images are similar” is the quantized, classficiation step which is trivial compared to doing the distance comparison across all samples with all other samples. My point was that this distance measure (using compressors to measure similarity) has been published for at least 20 years and that you should probably google “normalized compression distance” before spending any time implementing stuff, since it’s very much been done before.


  • Yeah. I understand. But first you have to cluster your images so you know which ones are similar and can then do the deduplication. This would be a powerful way to do that. It’s just expensive compared to other clustering algorithms.

    My point in linking the paper is that “the probe” you suggested is a 20 year old metric that is well understood. Using normalized compression distance as a measure of Kolmogorov Complexity is what the linked paper is about. You don’t need to spend time showing similar images will compress more than dissimilar ones. The compression length is itself a measure of similarity.









  • Barcelona is kinda famous for their pedestrian transformation over the last decade or two and the hiking and trains were excellent.

    I just think an American would find the salaries for the kinds of jobs that get you visas (healthcare, tech, finance) to be pretty underwhelming, especially if OP has student loans or other debt in dollars.

    Glassdoor says €66k/year for a doctor in Barcelona vs $154k/year in NYC. I assure you that anyone who can get a work visa to Spain would come out financially ahead in the US by a long shot. It also becomes pretty hard to travel to the US, even if it’s comfortable to live on the salary in situ. That’s not to say it isn’t totally doable. I do it.

    Are public health are and vacation time nice? Yeah, but anyone with a visa-worthy job with an American passport isn’t worried about the cost of employer based healthcare and pay substantially less taxes in the US. It’s great to be rich in the US, but really sucks to to be poor. I just think the unique position of people who can get work visas raises serious questions about whether or not it’s “worth” it.

    If a doctor can pocket an extra $50k/year (after college, healthcare, taxes) from the higher paying American job at the expense of paying for some human rights out of pocket, it’s hard to say that doctor shouldn’t hustle in the US for a few years first before finding a way to retire in Spain in 10 years vs working in Spain for the next 30. Visas for owning property or starting a small business are far more flexible and less scary than something attached to a particular employer, city, etc (work visa).

  • And where does that put the US for sending 50k Tons of munitions. I agree that the immediate moral culpability is with the person firing the missiles, but how many more bombed hospitals and dead kids before the US says, “no more”.

    Downvote away, but the district that is represented in that clip sure as fuck isn’t going to come out to vote for the Democrats. It’s not like Michigan has a huge Palestinian community and is a critical swing state with a history being ignored by the Democratic party, right? Right?




  • Sweden is basically Europe’s version of the American Midwest. For example, it’s a 10 minute walk across nothing but parking lots to get from the high density housing to the grocery store. Stockholm has around 6 story buildings and a housing crisis, which obviously follows from the lack of high density housing. Instead, all of Southern Sweden is one giant blob of suburban sprawl and SJ (Swedish national rail) is as useful and cost effective as Amtrak.

    Denmark is Copenhagen+ lots of suburban sprawl. Transit… existed.

    Germany is very much about cars, even if their transit network is robust. You’ll never hear a German say anything good about the trains though.

    France has 300km/hr high speed rail that takes you most places you’d want to go, but you have to switch to local regional trains for smaller destinations. No complaints. €2 tickets one weekend a month too.

    Belgium is up there with the Netherlands re: trains, but their bike infrastructure isn’t nearly as safe. It’s also like a day to walk across the whole country, so that’s not super impressive. All of BENELUX (Belgium Netherlands, Luxemburg) is half the population of the DC-NYC --Boston corridor, which also has a billion transit options (bus, train, boat, car, plane).

    Honestly? You generally can’t go wrong with the Krushevkas of Poland and the Baltics. High density housing with jobs, shopping, schools, and services close by and access to transit anywhere. The soviets really loved their street cars that are still hanging in there and provide service every 10 or 15 minutes , often using nuclear power (Bulgaria, Romania, Poland, Ukraine, Lithuania Slovenia).

    Western Europe is alright but Ljubljana just turned their entire old city into a pedestrian only zone, leaving the main road for busses only. You’d never see Paris do that to the Champs-d’Elysée.

    Belgrade built a whole new city across the Danube with high density housing after ww2. Unfortunately, they forgot to place the housing near any jobs which causes transit problems to this day. They also tried this thing out, which failed for the opposite reasons.

    Overall, Western Europe has the same affordability crisis as the US, but with lower wages and higher taxes. Granted, rents are generally lower too, but there’s a lack of high density urban housing everywhere that’s not already been gutted and turned into an empty city filled with nothing but tourists and airbnbs (Zagreb and Prague come to mind).

    By Northern European standards, both Portugal and Spain are poor, so they’re great to visit, but not really ideal for escaping the US. They’ve both been building out high speed trains like crazy in preparation for some EU rules that will finally tax the pollution from airplanes in a couple years. And Lisbon inherited lots of the EU financial services sector from London during Brexit, but going that route means you’ll be gentrifying a 500 year old city to work for British hedge funds.

    In general, though, the trains are pretty good, but that has a lot more to do with the logistics of trench warfare than being a thing targeted at helping working class people. That is, you can often find cheap flights that will get you to your destination faster and cheaper than the train. It’s not like there were daily passenger rail trips between France and Germany in 1904. Being able to move civilians in addition to artillery shells was just a happy byproduct.


  • wow. Someone besides either author got all the way here in the thread to downvote the guy saying open source communities shouldn’t keep people around who make volunteers uncomfortable. Like, what exactly was lost here? A guys right to do free labor? Python is just about the worst language for any task you can imagine anyway, yet someone is going around spending their free time picking 3rd party fights about the community that manages it.

    question for the downvoters:

    Why do you care? Personally, I like having women and racial minorities in computer science. That’s why I care.

    But why would you defend Tim? Please note that I’m not saying you shouldn’t-- it’s just clear that this was never an argument in good faith.
