Personally, I wonder why class-loading is not possible. In the end either a class exists in the closed-world that existed when the project was compiled, or it does not. Of course you cannot change the JDBC connector after it was compiled!

Maybe they could add a whitelist of "known" entry-points for class loading, as to avoid going through a list of 10,000 inner classes that existed at compile time but nobody will ever instance by name.

Parachutes don't work very well on Mars. Salt water kills delicate machines. Parachutes need very sturdy (and heavy) rockets.
> In the end either a class exists in the closed-world that existed when the project was compiled, or it does not

uh ? no, new classes are added at runtime all the time - at least in C++, dynamic loading of plug-ins is extremely common
>the driver can just pull over and stop

Yes, sometimes you can pull over and sometimes you just have to put the blinkers on, stop in the traffic lane, and hope for the best--even though it can be very dangerous. One challenge is that, with full autonomy, the vehicle needs to be able to very quickly deal with a once-in-10-years scenario in the least bad way--both for its occupants and for any other traffic on the road.
I suspect publicity created by this will easy recoup all expenses.
Yay for upfront pricing!!! Reminds me of how much I HATE it when I arrive at a site only for them to be super coy about their pricing model. You did it the way I wish everyone did.
“Building on that history, they should have a huge potential.“

One could argue that history might actually hinder urban development.

edit: In any case, I wish Naples the best of luck, as Europe needs more tech startups.
> I live in a small country where a lot of our businesses work with neighbouring countries. There is even a significant percentage of people that live here but go to work to another country. So, the kids' kindergarten will use a different time than your workplace?

I think that's a fairly small problem, and there's a good chance that it'll solve as many cases as it makes worse. For example, the longest single border within the EU is Portugal/Spain. Right now they're in different timezones, but that doesn't make a lot of sense - it leaves Spain in the same TZ as Poland, and with a noticeable unusually late sunrise/sunset. This would be a nice chance for Spain to sync up with Portugal/the UK/Morocco instead, all of whom match its longitude much closer.

Might well not happen, but it's certainly not clear that it'd make life more difficult than it is now.
I believe the subtext here is that Spain should use this as an opportunity to decide whether they should shift time zones altogether.
Even worse: it works. Jaywalking 2.0, here we come!

Yes, what the DC-X did was a parlor trick.

Vertical landing a post-orbit rocket onto a floating barge is not a parlor trick. The DC-X never did that. And vertical landing for real commercial orbital flights—then reusing those rockets for more real commercial orbital flights—is orders of magnitude more impressive again.
What I'm saying is that it breaks when you do a Class.forName(...), while if such class is known to exist at compile time, it is the same as a switch statement on the class name that returns a new object of the same type; and that second form would be a valid operation.
It might be "a huge waste of fuel" but the alternative is a huge waste of rocket. And the rocket is far more valuable than the fuel.
Fuel cost is less than half a percent of launch cost. Wasting fuel isn't really a problem.

If you want to land you need a bigger rocket for the same payload. But with how expensive rockets are, building them bigger and reusing them seems cheaper than letting them burn up. (And after a splashdown in saltwater refurbishment is way too expensive, so parachutes don't work well for reusability)
> You don't have to guarantee a minimum speed but you have to advertise the relevant parameters that you can reach at least a certain percentage of the time.

But this still suffers from exactly the same problem, just in a statistical way. i.e., what if someone's frequently in a place that has poor signal? How are you going to predict what percentage of the time they'll be in such a situation?
Obviously it's being spent on developing the rocket. My issue is that he specifically states that the mission is about "inspiring world peace". There are clearly better ways to inspire world peace than taking a lap around the moon.

It's not like they did a hostile take over, sued Google for API, and dump their failing project to apache or anything. Or refused to give TCK to apache harmony project. Or hell even tons of anecdote of Oracle buying out services just to bilk people with more money until it rot. Or have a clause for anybody using Oracle DB cannot benchmark.

I feel people easily forget or act as if past actions/history isn't a metric to judge a company by. You can't predict the future with your feeling you can only do it via past data/actions. That or is it tribalism dogma that their bread and butter tech is being harshly criticize?

It's called Daylight Saving Time (DST), not Electricity Saving Time (EST ?!). While some of the thoughts around it seems to have started with energy consumption (and thus cost) in mind (which proved useful in time of war), those were just consequences with little to no reason nowadays. The reasons are astronomical and therefore DST must be somewhat observed; it's the implementation approach that must be improved (IMHO together with the time-zones implementation), but people doesn't seems to understand it.

> The population of the U.S. is over 300 mil. How many people die or get sick every year because of our drinking water? It's got to be very small if any

All that means is “it’s very safe”. To call it “the safest in the world” is just blind patriotism. There might be long-term health effects caused by but difficult to attribute to water that are more prevalent in the US than other countries, for all we know.

> Just by you asking the question, highlights how well sales and marketing have worked when it comes to bottled water.

I’m not the person who asked, but no it doesn’t! All it highlights is how hyperbolic your statement was. It wasn’t an argument for or against bottled water at all.

I wonder how important Naples's local issues really are for a tech startup. Naples has a pretty bad reputation, but it's mainly about public services like waste collection, sanitation, water and infrastructure.

If I were starting a construction company or a restaurant there I might be concerned about mafia involvement, but as a tech company I worry more abut Italy's general bureaucracy and its broken legal system.

The somewhat baffling political situation doesn't exactly inspire confidence either (although I suppose I shouldn't be throwing stones from my UK glass house in that respect)
I think the most important one was people say one thing and do another. This is true both from the sales perspective and a user experience/user testing perspective. Here are a few examples

- People wanted cheaper mobile app analytics, but they wanted a brand they could trust
- People wanted a lot of insights, but they would never understand most of the charts

On the whole, products which are used during firefighting are are hard products to sell and differentiate on. Google/Fb/Amazon could build a product with 10% of the feature coverage and yet own the market.

Walking around in the trackbed is not a recommendable activity in Germany.

Acute Chest Pain: Causes of Persistent or Sharp Chest Pain
Agreed, thanks for the correction :) I guess I just used the terminology that's currently being thrown around (in the article and in the media here).

I just wanted to say that this will open up a discussion on which time to use (i.e. which time zone should apply :) ) and that if we are not careful it may complicate some people's lives.
I'm on a team collaborating with branches in CA, IN, and NC. Given the majority of us (including the lead site) are on Eastern time, the CA team tends to dread milestone reviews since they have to be prepared and on the ball by 6am; the first few reviews started 5am PDT, but that quickly proved to be too painful for our CA brethren. If Pacific states decided to drop DST without (at least) Eastern states following suit, collaboration would become that much more difficult.

I feel like Central and Mountain states have the geographic flexibility to decide either way without significant impact to interstate commerce on the whole. From the same lens, Pacific and Eastern states don't appear to have the same flexibility insofar as the potential for a 4-hour gap if Pacific states drop DST while Eastern states perpetuate the status quo. I'm just selfishly thinking in terms of synchronization, overlap, engagement opportunity, jet lag...as if 3-hour gaps weren't already a chore.

Modern cars can drive at their traction limit already, it's a solved problem.

https://en.wikipedia.org/wiki/Traction_control_system

It's been a safety boon to have a computer limiting power to the wheels when they slip, humans are really bad at estimating how slippery the road is.

Estimating for the road ahead is a different problem, but there is data to feed into that estimate.
Thanks for such a good feedback. Honestly, I'm a still bit confused how exactly to proceed with the point 1 but I'll try to figure that out. Thanks

Sure. This is just pushback to the recent hype "it has full autonomy capabilities [small print: except not at all]". If the first cars had been marketed as "better in every aspect and in any conditions", you would have seen similar reactions.
Your question suggests a dismissal of N's work.

Is that dismissal based on an serious engagement with his work?
I'd be interested in seeing an argument why one should not let N be a guide. It would be nice (and unexpected) if that argument was informed by an actual reading of N's main works.
Ask HN: What do you consider when choosing a 3rd party package?
A positive interpretation is that the original piece wasn’t very substantive, and tossing it off the front page was a way to make room for the more-substantive articles (which we’re now commenting on).

A less positive interpretation is that voters have very little say over what goes on the front page — or more specifically, what stays.

The author makes it sound as if there have been no material changes to programming languages recently but unless you've been hiding under a rock you will know that this is not true.

He compares Python to C. Come on, please. It would have been more relevant to speak about the LLVM project and how that enables architects to build more expressive languages which can still make use of 30 years of optimization wisdom (most of which was built when CPU's were much slower)

What about mentioning languages like Rust which are designed for high concurrency and zero overhead which let developers write software with the safety of python but the performance of C.

What about mentioning that some old languages, like c++, have evolved though new language features AND guidelines into much more effective languages to guide us into the future of concurrent programming (the easiest way to enjoy the speedups of yesteryear)

They have been developing the BFR for more than two years and won't launch one in the next two years /s

Maybe people have wrong expectations from working in software. SLS has a longer development time with a more tried-and-true design, and yet their deadlines slip as bad as those of SpaceX
So far I've had at least 4 failed side projects/startups, and one mildly successful product (so far).

Back in 2014 I tried to build a product recommendation service based on Reddit subreddits, where I would make money from Amazon referrals. I actually got to the front page of Reddit and Hacker News, but Amazon rejected my referral application, because apparently they don't approve any websites that have a grid layout of products (too similar to amazon.com.) I retried a few times but still couldn't get it approved, so shut the website down.

My first attempt at cofounding startup was a social network for skateboarders: http://hdwr.co. It wasn't a great idea but our team was pretty amazing. We set up a lunch with Tony Hawk (although nothing came of that), and were in talks with The Berrics (a big skateboarding brand) about a partnership, but couldn't work out a deal. In the end we didn't have enough users or growth, and after a few years everyone got bored and we shut it down. Never made a single dollar.

I had an idea for a mobile game that I thought would be fun: https://itunes.apple.com/us/app/boops-boops-swoops/id1128234...
It had an "AR" mode, a few years before that became a big thing. Anyway, I executed poorly and the game sucked. It just wasn't very fun, and I didn't make any sales. I learned that I'm not very good at making games, and even good games are a lottery ticket.

Second game: https://sudoblock.com
I had a lot of fun building SudoBlock, and it was really good to learn React Native. It was awesome to build a single app that could run on Android, iOS, Windows, and web. I posted it on Reddit and tried some other marketing things, and I earned a total of $30 from in-app purchases. I learned that I'm still not very good at making games. I think the execution was a tiny bit better than my earlier game, but still pretty bad. And the game just wasn't very fun or addictive. If I ever do another game, I should probably hire a designer. But I probably won't, because I enjoy doing everything myself, even if it sucks. And maybe I'll get better at it eventually.

My current project is FormAPI (https://formapi.io), which is a B2B SaaS service that I've bootstrapped. I launched about 11 months ago, and I'm not really comfortable with disclosing the revenue, but it's doing really well. I'm excited to keep working on it for the next few years and seeing what happens.

I'm surprised about this.

I get that there can be circulating cells,
but the probability of them successfully metastasising in the early stages is very low.

Normally it's only later stage cancers that end up spreading.

I guess it's down to the immunosuppression making metastasis more viable.
In my experience, americans say “everyone” when they mean “everyone in the country” and “the whole world” when they mean “the usa”. This may shed some light into the psychological context for such decisions (or lack thereof).
And it's not only the poor and forgotten areas that aren't electrified.

- The link between Hamburg and the island of Sylt isn't (one of the most profitable ones)

- The ICE-link between Hamburg and Puttgarden (to Copenhagen) isn't (one of the most busiest around 110%++ capacity)

- Large parts of Swabia, one of the most industrious areas of Germany are completely un-electrified apart from the ICE-link between Munich and Stuttgart. Getting from Aalen to Lake Constance or Kempten via Ulm you will see a lot of "Mittelstand"-Companies but not a single electrified track.
I feel the same way as the author.

I have a theory that we're not caring as much about performance and good software because we don't have to, because Moore's Law has led to machines that are fast enough to run our crappy and hastily written code with acceptable performance so the majority of users do not really care about it running more efficient.

In the past, when computing resources were constrained we had to care about performance just so we could release software that worked good enough so people actually wanted to use it.

How do we get people to care about performance and efficiency in software? I don't know.
This reminds me of intel's optane. Yes they overhyped it and it doesn't perform 1000x faster than SSDs. But you have to consider that SSDs required decades of improvements to become viable and cheap. Even when Optane was a first generation product it was already better than SSDs in terms of latency and IOPS but despite that people thought it was a massive failure.
But it's not "all" there - some things are reserved for the enterprise edition. So if people start adopting it now in the hope that its remaining technical limitations will eventually be adressed, we might discover that the improvements only apply to the EE version, while the open source version is kept more or less where it is to encourage people to pay up.

If you read the manual for the traction control it is full of big warnings on every page,'Does not cancel out physical laws'. It is not a solved problem, it can only do as best it can uphill until car does not have enough traction to continue upwards. At which point the car will slowly glide down or into the ditch.
The Ultimate Sensor Battle: Lidar vs. Radar
I have zero issues with this. The rich tend to adopt or do what the rest cannot very early and a good many things do trickle down. Just look at all the safety features on entry level cars these days, most used to be pure luxury items. Even the idea of an affordable EV. the go into your home and see every day items and just look at the price changes on big ticket items.

I remember the days in the 70s when flying was too expensive for families to consider. Even making a long distance call was reserved for special events.

He's been one of the most influential philosophers in the 20th century, both through Heidegger's influence -- especially in France, and through neo-Marxist (Frankfurt school) engagement with him. Finally there's Freud and his school of psychoanalysis, who took a lot of inspiration from N.
Solvable, indeed - in the Dartmouth-1956-workshop meaning of "solvable": there's as of yet an unknown amount of research to be done, and it looks reasonably complex to be hacked at by a dozen people over the summer. Therefore, a few man-centuries of research and development will surely bear fruit.

I'm pretty sure that prior to this silly trade spat China simply charged their national sales tax (17%) against imports - which is fair since that puts imports on a level playing field with local products. This is not unusual, NZ, where I live, does the same thing (15%). US states with sales taxes do too.

I think China is targeting pork and soy beans (lowest prices now in a decade)

For $200 million? I can’t think of any. Remember the world economy is approximately half a million times bigger than the amount of money being spent on this. Even the most recent summer Olympics (which are, I think, supposed to be world peace promoting) was 655 times more expensive.
