Maybe: fewer tourists, more people move back to the city and other industries begin to re-emerge. But right now, much of Venice is dying off — except for the tourist shops, because of the tourists. It’s turning into an EPCOT Center version of Venice.

However, it would be interesting to see what the per-tourist expenditure rates have been over the past five years; my hypothesis is that per-tourist spending is down despite total tourist spending being up. Cruise ship passengers are a bulk of visitors and they don’t spend much (since they sleep on the ship.) So that crowds out potential visitors who might spend more money.

As another commenter said: there is a equilibrium between tourists and locals that needs to exist. My opinion is that shoulder-to-shoulder people is actually harming the city. There are actually proposals to limit the numbers of tourists — those proposals from the government wouldn’t exist unless there was some sort of problem.

I am not a Venice expert and have only been there a few weeks, but seeing masses of people buying cheap Chinese-made knockoff Murano glass from vendors who aren’t even Venetian (nor even live in Venice) — it’s hard for me to accept that is “good” for Venice or Venetians.

I actually did use a system like this previously, but somehow the site just stopped accepting the codes from my TOTP app one day. I restored the official blizzard authenticator app from a backup but that wasn't working any longer either.
I have an electric car and I know many people have electric cars. Each have their own motivations, for some people it is to save on gas. Others for carpool access, while still others are for environmental reasons. I doubt Nissan Leaf is a great status symbol
I spent a good 10 years of my life in a legitimate attempt to become an NFL player. If you saw me, you would have said it was a long shot - of course it was - but I didn't let any of this get to me and I worked extremely hard to get to that goal. But I failed. I started for 3 years on my D3 college football team but at the end of my senior season I was still laughably far from NFL caliber. When I put my pads away for the last time it was devastatingly clear that I had completely wasted on average 20-30 hours every week for the past 10 years of my life, hours I could have spent making friends and/or becoming a normal person.

You know what I did? I moved on, fast. And that is the solution to failure - move on quickly. And I did move on, and have found success after.
Yes. Air travel is quite safe, for example, but not danger-free. We as a society are willing to accept some death here and there so that the rest of us can go on interesting vacations.

However, that still isn't illegal. That would be a civil dispute. "Illegal" is implying that he could go to jail and that he is breaking a law. Just nitpicking, but I think that "illegal" is a much stronger idea than simply "could get you fired or could get you sued."

I leased a Ford Focus Electric for 2 years before purchasing a used Tesla. After just a few months it became apparent that the Focus was just a compliance car afterthought. Instead of putting a little thought into battery placement, they simply threw it into the hatchback which reduced storage and left little weight in the front of a front wheel drive car. Instead of converting the engine compartment into a frunk, there was a mass of loosely placed tubes and wiring. The result was a car with limited storage that was downright dangerous to drive on a wet road due to lack of traction, with an effective range of about 50 miles (hope you don't have to use your heater or AC). Ford Sync was also absolutely miserable to use - slow, unintuitive and clunky.

On the contrary, the Tesla has been an absolute joy (perhaps even more so after driving the Focus for 2 years). The performance, interface, supercharging, storage, aesthetics and customer service are IMO far superior to any other electric vehicle on the market today or even announced for release in the next few years.
I should also add that if we don't solve this, we basically destroy the planet for all future generations.

"Marginal increase in regressive taxation load in the present" doesn't seem that bad, in that view. Though I do agree it affects the politics of it.

Of course, there's also the non-neglible social benefits of lower income taxes.
I've heard both but personally prefer dēmən. Dāmən just sounds goofy to me, like someone trying to pronounce Gaelic (or Welsh!) without having learned anything about it first.

I wish some doctoral student in classics would write a blog post and settle the matter once and for all, but in the meantime it seems to come down to personal preference. There's precedent in other English words for either pronunciation (e.g. aeon, aegis, archaeology, Athenaeum, and Caesar on the one hand; aero-, faerie, and maelstrom on the other).

Until someone who actually knows what they're talking about weighs in, I'm tossing this whole argument in the same dustbin as emacs vs. vi and tabs vs. spaces. There are better things to waste our time on. :)

I bought a Tesla primarily for the Supercharger network. Any other EV is DOA if you need to long distance travel in a reasonable amount of time (I do like the Leaf and Bolt, but they are not practical outside of a commuter car).

The operating costs are less than half of the Tundra pickup truck it replaced.
The code that you can't afford to rewrite is the code that is hairy with details. The details are some mix of essential and incidental complexity. The ratio is dependent on the degree of fit between your business logic and the framework, the primitives it's built out of, whether it's third-party, custom framework, custom language, whatever. And of course any custom component has its own complexity; it should be additive, but it may still be large. A good fit - an excellent fit - means your business logic is clear, concise, and is operating over abstractions that map directly to the business concepts. A poor fit is speaking haltingly in unidiomatic language, too verbose, aggregating globs of ugly code, losing track of the forest for the trees, etc. But it'll be easier to find average devs who are familiar with the particular style of thicket that ends up coming out. We even have names for the scar tissues that grow around each glob, helping them interface - we call them design patterns.

There's no hard and fast rules, it seems to me. Use a small fraction of lots of different third party bits and pieces and you get a recipe for pain. I'm fairly certain there's no more productive way for engineers to code than to raise the level of their language into their business domain - http://www.paulgraham.com/progbot.html - but this is the custom framework / language approach. I'm also fairly sure that it's hard to scale an organization around this approach because of the incentive problem when hiring developers. I think it only really works for startups that are composed of a bunch of hackers with decent equity stakes. It doesn't work out for employees, unless the company ends up moving the needle industry wide, like Java or Rust or React, and that's really rare, too rare to bet on.
His terminology might be a tiny bit off, but I think it's actually pretty close. Intel's optimization manual (https://software.intel.com/sites/default/files/managed/9e/bc...) in 2.4.2.6 says "Micro-fusion fuses multiple micro-ops from the same instruction into a single complex micro-op. The complex micro-op is dispatched in the out-of-order execution core." So while the title probably might have been better as "Micro-fusion of µops", "Micro-op fusion" isn't particularly far afield.

It's called "micro-fusion", by the way, because the µops are fused together from the point of view of parts of the processor, but then "unlaminated" to be executed. The alternative is "macro-fusion", where certain instruction pairs (cmp-jcc) are fused by the decoder and treated as one after that. Using Intel's terms, RMW-type instructions are indeed always handled internally using micro-fusion.
> This is really not likely to compete well with batteries and EVs in terms of efficiency.

The problem of EV is not their efficiency though, it's that they are extremely heavy for the range they provide, due to batteries still having terrible specific energy and energy density. And they basically only work in temperate areas (good luck running EVs in winter in Yakutsk).

ICE have much lower efficiency, but the sheer amount of energy in the fuel more than makes up for it.

And electricity storage at scale is still a problem we're nowhere near solving. Carbon-based fuels are extremely stable, if the generation process is not too lossy, they make for a pretty good storage medium: light, easy to manipulate, shelf-stable, and usable as-is.
Interesting, I've been doing lots of searching and all I can find is forum or blog posts of unverified people, some saying that VT-d is enabled, but most saying it is not supported/enabled. In fact, if you look at the presentation by Russ Sevinsky that is referenced in your first link, it is specifically said that Apple hardware does not support IOMMU [1]. So I really don't know what to think.

1: https://youtu.be/q0HthE3qDMw?t=415

edit: I finally came across the below link from Apple which does seem to imply that IOMMU VT-d is enabled on Macs that are 2012 and newer. On anything before that, though, and DMA attacks could own you. So uh.. don't run macbooks that are 6 years old, I guess.

Dying for corporate is not a hill you want to die on.

There are certainly companies which are worth putting in 100% effort, but this isn't one of them for OP. But the reality is that most of us need a job.

Who can we blame for not being able to perfectly match employers with employees and giving everyone a fairy tale ending?
In case you’re wondering why you’re wrong; you could have passed the group to someone else, you could have started a discussion of where to move the group, you could have done any number of things rather than just killing the group because you didn’t want to cough up $15/20.

Great progress on road related fatalities and smoking. While any number of road fatalities is too many, that decrease is despite increased usage --something we in the US have not been able to replicate, but this shows if you take road safety seriously, it can be improved [now, I have no idea if they initially had a relatively high number to start with]

The 2007 documentary "The King of Kong: A Fistful of Quarters" is my favorite movie of all-time, I must have watched it at least 40 times. Trailer: https://www.youtube.com/watch?v=8hBs2oFjSWk

For those who haven't seen the film, the contender Steve Wiebe sets a new record live at an arcade tournament in Funspot (NH) but reigning champ Billy Mitchell sends in a VHS tape with an even higher score.

The video gets fuzzy and looks suspicious but Mitchell's toadies in the group immediately accept the score, despite refusing to previously accept a VHS tape from the contender Steve Wiebe.

Since the movie came out both men were left in the dust by new players, but recently the score-keepers slow-mo'ed Billy's tapes and the Donkey Kong levels render the way MAME does them, not the actual arcade hardware. The current No. 2 ranked player (Wes Copeland) is basically corroborating this by running his performance through an app and determining the point ratios are off (e.g., too much from hammers).

Personally I don't think Billy's a bad guy, and the film actually shows him performing selfless acts for others, but if this allegation is true -- and it's hard to argue with the data -- I do think this seriously compromises his integrity and position in classic gaming history.
Yes and no - they have the origin in the same word, but as the article point out the two spellings have acquired different connotations. So they are not exactly the same word anymore.
I think you are missunderstanding this a bit, hack has async io.

If you have only 1 external system that both indexes the data and stores it, this won't help you that much.

But if you have an indexing system and another, with many read slaves, that stores the data, then async will help you.

You will do 1 external io request to retrieve a list of ids/identifiers then as many replicas paralel requests to retrieve and format the data.

Office is a productivity drain because they successfully pivoted away from the "productivity" market to the "job protection" market.

The former was a product Microsoft sold to employees on behalf of the company.

The latter is a product Microsoft sells to employees on behalf of the employee (although on the company dime) and which the employees use to protect their job title, against the interests of the company.

These kinds of pivots are inevitable as these core software markets become commoditized. You can only make money off a software product for a decade or so before lower cost competitors will come in and eat your lunch.

Ownership also takes all the risks. Profits is the reward for taking risks.

All employees can also enjoy profits, by becoming owners of a company, either through stocks or starting their own business.
In 2008, LANL or ORNL published a paper on exactly that. I can't find my PDF copy, but they were suggesting making use of cheap electricity and waste heat from a nuclear plant to create carbon neutral fuels. ISTR they were calculating that it would be cost competitive with gas at $4 or $5/gallon. Probably not something we'll see in the US in the near future, but certainly possible in countries that levy more taxes on fossil fuels.

I knew a startup that did something along these lines. Started out as a healthtech startup, decided to have an ETH-based ICO to raise funds, then paused and sat on their ETH reserves when the price went up while they "re-evaluated" their startup. Businesses have found that living off hype leads to easier riches than actually working on something.

It's like watching the South Park startup episode in real life.

I think you maybe be on a bit of a red herring here. Yes, values vary by age group but I'm unconvinced that cohorts change predictably over their lifetimes especially if we consider a more international view.

However, values aside I think there is an impact from neuroplasticity in terms of how younger people adapt more readily to new technology, etc.

I do wonder where the line is. Not in the ethical sense, logically: do you expect to run your business as a one-man-show forever? If not, paranoia ahead: you'll see your employees as yourself-the-employee.
Me, I wonder about the relationship between Hindu devas, which are benevolent, and Zoroastrian daevas, which are basically demons. And then there's the Zoroastrian god Ahura Mazda vs Hindu asuras, which are demonic.

It's like Zoroastrianism just reversed the Hindu categories. I get that there's been millennia of bad blood, but this seems rather extreme.

And software demons are generally benevolent, not demonic. So does the usage come from Hinduism?

Ask HN: What Is the Absolute Cheapest Car to Own and Drive?
Let's suppose I wanted to buy a car. But I'm brand agnostic and mileage agnostic. That is, I'm willing to buy any car regardless of its make and model or how old it is. Now, I'd like to buy a car which is going to cost me the absolute least money of any car new or used, that I can buy, over its lifetime, including repairs. How would I determine which car that would be? Now, in thinking about this, I see quite a lot of problems, which include, but are not limited to:
-Fluctuations in price of the used car market
-How to calculate the cost of future repairs
-What the cost of gas is and that related to how many miles will it be used in an average week
-Tax deductions, if any
-What the future cost of gas is projected to be
-How much insurance would cost (sub-problem, what would the cost of the cheapest insurance be?)
And of course, how to monitor all of the cars from all of the vendors/markets for a given area.
Now, I don't have an answer. It seems like a problem involving multiple domains, requiring huge amounts of statistical data, recurrence relations, data from multiple sources, etc.
But... in thinking about it, I think this would shine as an interview question for my future company (assuming future applicants don't read Hacker News). But, what does the HN community think? What additional things need to be accounted for if I wanted to find and buy the absolute cheapest car?

For the problem of bundle size, it saddens me that Google's Closure Compiler (specifically the advanced mode) hasn't gained much traction. This provides fine-grained tree-shaking to minimize the bundle size. But this requires static analysis of the whole program, which is at odds with the dynamism of JavaScript. Maybe now that static typing is coming back into fashion, the Closure Compiler or something like it will gain widespread adoption.
Ask HN: Are you optimisic or pessimistic about the future?
I am leaning towards pessimistic because I think it’s going to take the entire world as a collective to solve the worlds problems (hunger, climate change, etc...), and I don’t think we’re close to having that happen. Though I will say having powerful individuals with a huge sum of money having their lifes mission to solving this problems wiggles the needle a little towards optimistic.

Technologically I can’t see how the world won’t be a distopian future a-la Altered Carbon with technology being used to reduce privacy and credibility.

It just seems like there will always be this cycle of opression, and those with incredibly strong values fighting for our freedom. Ebb and Flow of the human race I suppose.

I wasn't aware of that much progress on your first link.....I'm curious to know if at the same time they've put any effort into improving the half-assed Excel COM API.

Totally agree on the Power Query thing, if they'd support pandas + power query + embeddable Power BI objects in Excel + seamless integration with cloud functionality (there's still no way to use Power Query in SSIS for goodness sake).

Using pandas in an Azure function and then consuming that from Excel and displaying in Power BI visualizations, all within a nie little wrapper you can email around or whatever would just be a killer app. This is one of the few advantages Microsoft has over the Amazons and Googles, I wish they'd take advantage of it.

The syntax in your example is lovely and this is something I've wanted in Excel for a very long time.
