Carlton City Hotel Singapore, I arrived there in the middle of the night with a printout from booking.com of my (already-paid-for) reservation.

The staff said they don't have my reservation, told them to check booking.com, they replied they do not have access to booking.com, a third party manages that for them which was unavailable at night. In that moment I realized I was putting way too much trust in that website. I was able to pay for a new reservation and later got the booking.com payment refunded. Luckily the hotel was not fully booked...


> they replied they do not have access to booking.com, a third party manages that for them which was unavailable at night.

I guess that's primarily the hotel's fault. They should not give rooms to weird third parties. But with the market shares of the big booking sites that would cause them significant loss of bookings.


Similar story here. Some years old IG account, logging in maybe once per month. One day few months ago instagram decided to deactivate my account and wanted my selfie to get it back. I never really used the platform so I'll just stay without.



Quite aside from all the injustices, lies and pushes for military action by the U.S. since the end of the Cold War, this article takes a blatantly one-sided view that essentially seems to state "well, you shouldn't have pushed Russia into a corner. The invasion is your fault".

As another reply below says, no mention of Russia's own military aggression with neighbors under Putin's rule or of the fact that if NATO grew closer to the country's borders, it mostly did so with the full willingness of the countries that later joined. Having Russia close to them caused a choice and that choice (fully within their rights as countries) was to become closer with the NATO alliance and western Europe because they found it preferable to possible Russian domination.

The writer describes war and military provocation as a lucrative business and insinuates that western greed motivated the expansion of NATO, but sidesteps that Russia's own military/political moves are often no less motivated by the same things where possible.


sure it is one-sided, but at least it tries to give a plausible explanation rather than all the inflammatory nonsense about putin being a madman hellbent on conquering Europe. I find the general lack of interest in understanding the motivations of the opposition very disappointing

people in this very thread are saying things like "his actions make no sense." Frankly if that's your contribution, maybe realize you're out of your depth? can we at least _try_ to learn from this so we can prevent future war?


> There was a near universal understanding among diplomats and political leaders at the time that any attempt to expand NATO was foolish, an unwarranted provocation against Russia that would obliterate the ties and bonds that happily emerged at the end of the Cold War.

Did they put it on some legal paper?


It is interesting in the sense that it fails completely to mention the multiple countries Russia has invaded over the past 25 years. It treats NATO's actions as happening completely in a bubble, ignoring Putin's own provocations. It also assumes the countries that have joined NATO aren't deciding to join, but instead being consumed by NATO.


How does one get started? How does one get the necessary experience without taking unnecessary risks?


By getting a boat. Getting on someone else's boat is good too, as you can get experience and learn from them. Sailing is easy - you don't need to win races when cruising around the world, so the finer details of trimming will be wasted on cruisers (you can always pick them up on the way). Navigation and traffic rules shouldn't be hard to pick up for the average HN crowd, although yachties like to make a fuss about it.

I did a few RYA training things that cost a lot of money and got me some papers that nobody ever wanted to see (they're important if you want to charter a boat though). You can just buy the syllabus and gain the knowledge by online learning or video courses instead. I recommend going that route - the knowledge in the syllabus is important and very useful. The formal course in a classroom and the certificate are not. Practical knowledge is gained only by going sailing, making mistakes and learning from them, but it helps if you know the knots and the parts of the rigging beforehand.

But the real learning only begins when you get your own boat and have to fit it out and keep it going. Boat maintenance is hard and there's a lot to learn. You can initially substitute money, but that stops working once you get to remote areas where there is simply nobody else to pay to fix your boat and you will have to do it yourself or give up. Many decrepit boats in remote locations are on the market very cheaply for exactly that reason.


Do you recommend Jimmy Cornell’s world sailing routes books? I have about $100 worth in my wish list, spiral bound, I’ve been waiting to purchase until closer to departing on a circumnavigation.


They're great, but you'll end up looking at them once a year when you do your passage planning for the next season. Excellent resource, but a bit pricey and heavy to sail around with.


Jimmy Cornell’s world cruising routes are widely considered to be a great resource.


Finding a boat on a budget is easy. What is not is finding a harbour post to moor it. At least here in south of France, this can get really expensive and you may have to wait for years before getting one.


> you don't need to win races when cruising around the world

Brings to mind this interesting story of a race like that gone wrong: https://youtu.be/h0WgqMn5lTI


You might be able to find a sailing co-op in your area. I'm a member of one that requires 30 hours of volunteer work, which you can gain experience in a wide variety of things - fibreglassing, painting, plumbing, electrical, rigging, etc.

We've got a fleet of 6 27' - 30' boats which are great for day sailing and week long vacations.


How I started, YMMV:

1. Watching a lot of YouTube, see my list of channels in another comment, and the note about not believing everythin they do is correct.

2. Joining the local dinghy sailing club. It's cheap, and although I don't really care about racing the skills were mostly directly transferrable to larger boats. Plust contacts are really useful.

3. Get on other people's boats as crew. I own a 43ft yacht, my friend sails it with me. It costs him nothing :)

Later, when you have tried it out and got some experience, take your Day Skipper (RYA) or equivalent course (the ASA in the US runs some). You should at this point have a reasonably good idea of your skills.

At some point in the process, start looking at yacht listings. Yacht World would be a good start. Get an idea of the market. You will work out how much you need to save, and what sort of prices are reaonable.


get classes, pretty unexpensive. After your first 5-7 days when you learn basic skills you will receive plenty of invitations to crew. Not unlike the corporate world, too many chiefs, not enough workers. Good crews are in high demand (and you can bring significant other, friends). Lots of owners are clueless. Lots of big boats are looking for crews, typically an ocean crossing. Think Panama-Tahiti. Expenses, including flights, paid


Is there a way to seamlessly migrate current email address to another email provider and what steps can be taken so that it will be even easier to switch provider next time?


Are there any air quality devices that work well outdoors in all kind of weather?


Can anyone explain what role does ASML play in TSMC's advantage over other fabs? Let's say TSMC and other fabs can all source same equipment from ASML, what else exactly does TSMC do better than the others?


I am super scared of accidentally exposing a port to the internet. Is there a service / tool that I could provide with a list of all my public IP machines and it would keep port scanning them periodically, sending me a report of all open ports by email each month and sending me an email each time a new port becomes open to the public internet?


Shodan has a monitor feature. [0] I haven't used it myself but the description looks like it's about what you want.

[0] https://monitor.shodan.io/


I use "nmap" for this.

  $ nmap example.com
  PORT     STATE  SERVICE
  80/tcp   open   http
  443/tcp  open   https
  1119/tcp closed bnetgame
  1935/tcp closed rtmp


A more complete answer using nmap and cron:

    MAILTO="youremail@yourdomain.com"
    */30 * * * * nmap yourdomain.com | grep open > nmap.log.tmp; diff nmap.log nmap.log.tmp; mv nmap.log.tmp nmap.log


I think that shodan.io can do this, if you give it an IP it will monitor it and email you about services it finds.


Slightly offtopic but I think the problem of rogue addons applies to firefox as well. I wish it were possible in firefox to limit which addons can be loaded on a per-container basis. The extensions I want loaded on banking websites, social media and youtube are completely different. And limiting them per-container makes it a relatively simple mental model to reason about.


I was just thinking about this the other day. I would love to keep google/gststic blocked in noscript on most containers except the Google container.


In that case you can use multiple profiles.


I was able to learn how to use containers quite quickly and some container addons make it very easy to use them. Not so much for profiles, setting up multiple profiles seems very tiresome and honestly whenever I look up how to create multiple profiles I lose interest. Would really love a solution that is as easy to manage and use as containers and allows to control which addons are allowed to load/run.

Edit: Also IIRC multiple profiles cannot be synced across devices through the same firefox account while it is possible with containers


The point of containers is to not have to juggle a bunch of profiles.


Hm, not really, they have different use cases, and Containers was never meant to 100% replace Profiles.

Containers are for being able to keep separate identities in the same browser window, but on a per-tab basis.

Profiles are for being able to separate different browser instances, with all their settings, extensions and so on.

While Profiles was used before to do the same thing that Containers now allow you to do, there are things you cannot do with Containers that you'll need to use Profiles for. Having separate extensions for different sessions is one of those things.


It's impressive how far China has come in just 2 decades. How significant is this achievement space technology wise? I still remember the first rover on Mars and it was a really big deal in my eyes back then.


The significance is that that space travel is becoming a commodity. In the recent past we had several countries attempting moon landings. The Chinese landed successfully. The Israelis had a failed mission recently. The Indians crashed (on purpose) a probe on the moon. The Japanese, Iranians, and probably a few others have each launched satellites into orbit. It's getting crowded there.

The other significant thing is that there is now a bit more urgency to the matter of getting humans back to the moon and eventually to Mars. The Chinese are preparing to set up their own space station and are obviously interested in going to the moon and Mars and they seem to have the technical capability to get there. It's a bit like the early days of the space age when NASA and the Russians were competing for getting there first. NASA seems busy fighting domestic battles for funding rather than getting stuff done. They got a lucky break with SpaceX having a bit more focus on that front and proposing something that might actually fly. Now they need to get serious about actually making that happen. If they don't, somebody else will.


About the urgency to go to the moon: China and Russia is planning a moon base.


What probe did Indians crashed on the moon on purpose? I wasn't able to find anything about it.

Is it the Vikram lander that was destroyed while landing because of a software glitch?


Assuming the Zhurong Mars rover can be successfully released in the next few days, China will become the second country in the world with a working rover on Mars.


Third : The Soviet Mars 3 rover was on Mars in the early 70s. Still a great achievement!


I think it’s very significant. Interplanetary navigation and retro propulsive soft landings are tricky to get right. Several recent lunar missions have failed and historically about half of missions to Mars crapped out. China is rapidly racking up a very solid track record with their lunar and now Mars landings. Also rovers are a significant step up in complexity and capability from static landers.

The Long March 8 architecture looks like it’s suitable for adaptation for first stage recovery, and they have expressed the intention to attempt it, so China are lining up to overtake Russia as the strongest competitor to the US in space technology.


When the entire world moved their factories there and then started to import everything, what else would you expect? It's funny how communists beat capitalists using greed to their advantage. Now it's a matter of time that communism will be seeping through every country fabric and it will be the end of the free world as we know it.


Consider that China is banned from the ISS and other kinds of space technology collaboration programs. China had to develop all space technology on their own. Some perspective on how significant.


They also steal research, but, I understand the point you are trying to make.


It is not like even you are open all US research to one country in an instant, they would be able to build their own next decade.

China did a really good job figuring out the know-hows and had their domestic team geared up for the job. That is nothing to be dismissed, like tired 'China can't do shit without stealing our technology' circlejerks would like to indicate.


When you look at the history of space travel. One of the first space programs (NASA) originated from Germany developments. North Korea nuclear weapons from Soviet undercover collaboration. Not familiar with specifics for your claim above, but just stealing is a miniscule part of what is really required for this type of effort


Space research in the US started before the Germans joined, but it never worked... The US had to bring Germans to make the whole thing successful.


I think you mean, German Jews brought their innovations to the US because Germany tried to kill them.




Wernher von Braun, probably the most prominent German rocket scientist who was a pioneer of the US space program, was a Nazi.



In the context of for-profit business I wholeheartedly agree with you, but in the context of space exploration, if there is research about how to go to the moon and Mars that can be "stolen," isn't the moral culpability on whatever entity is hoarding that knowledge?

Or is going to the moon and Mars the achievement of certain parts of humanity, to be kept secret from other unwanted parts of humanity?


I think some evidence is needed for the accusation that they stole significant space technology research.


Not downplaying the achievements as they just achieved something the Soviet and Russian programs could not even at the height of their powers during the space race. But there are plenty of countries most notably Russia that have allowed China to purchase military/dual use technologies. Hardware such as advanced fighter jets, missile and rocket technology, and there’s also the huge numbers of tertiary education students who leave China for education in advanced fields before returning home for their careers. All of this will have contributed in some way to advancing China’s space flight program.

They didn’t achieve this in a vacuum, let’s not perpetuate the notion that China is isolated from the rest of the world.


Did the Soviets make any major attempt for Mars? I thought that after the moon, they were mostly focused on Venus during the space race. Their ~28 Venus missions were no joke, with up to 5300 kg payloads for lander + orbiter, comparable to the Zhurong lander + orbiter payload of 5000 kg. Perhaps someone more skilled at rocket science than me can comment on the relative difficulty of moving mass to Mars vs Venus. From the table in Wikipedia's delta-v article they look about the same.

That said, congratulations to China for this achievement, and the more rovers we have on mars, the more science we learn. I hope China also has a new space telescope on their to-do list.


Soviet Union sent probs on Mars: https://en.wikipedia.org/wiki/Mars_3


And the US had to bring German scientists to have a space program.


[flagged]


They steal research from "the many countries" that haven't been to Mars? That seems quite an odd accusation. You just handwave the need for evidence away as if such an accusation can be assumed to be true. Arresting people on charge of espionage doesn't mean that those people actually engaged in espionage: proper due process must be finished first before that conclusion can be drawn. Also, stealing trade secrets in certain areas has got nothing to do with stealing secrets in space technology, so it's whataboutism at best.

How exactly are they supposed to steal research when they've been banned from space collaboration programs? Assuming that even if they did manage to steal some research, how can that strategy possibly be more successful than countries that haven't been banned from collaboration? That makes absolutely no sense.

No, China developed their space technology on their own, with their own research, by their own hard work. This is the result of accusing them of stealing and banning them: they go their own way, successfully.


I'm to tired for a debate, but this is a start:

https://defense.info/re-thinking-strategy/2020/10/the-fight-...


FYI , you know that US was caught spying on other countries, including economical espionage(on Airbus) and I remember I seen recently some video about US getting access to some Russian equipment and the hyper patriotic narrator ... now imagine I would invent some stupid accusation that SpaceX is built on tech stolent from Russia and airbus without any proof just some unrelated links about that a guy maybe stole some seeds or some documents that you can't trust because of the political and racist environment in US.

If the tech is stolen I suggest you either do some better work on presenting this or better wait for someone less lazy, more competent and with more knowledge in this domain to do it. Some US gov employee could either show or fabricate better evidence then you.


There is quite a bit of whataboutism when Chinese espionage comes up, however the key difference is that the government has a financial interest in most companies and often shares loot from foreign competitors with local businesses.

Yes, the US, Russia, France, etc. do this too. The big difference is when the government gives Lockheed the design plans for a new Chinese fighter jet the goal is to develop countermeasures and defeats for its technology, not to clone it outright.


My issue with this comments here is, do you have any proof? China made a rover with 6 wheels and this means it is stolen? WTF is the "round corners" issue again?

I would like to see something more real, like Patent 1234 "Mars rover with metal wheels" then show how China somwhow broke this ridiculous patent. OR show that US rover contains some super secret tech that is also present in China stuff.

As far as I know China can send his smartest people in US, EU or other countries to learn advanced stuff then bring them back in have them teach in their universities. Combine that with a large population and a hard working people that have respect for science I can easily see them getting number one in sciences and tech.

IMO, keeping things secrets is not a valid long term strategy, look at the Apple new CPU/GPU people are reverse engineering it fast. The only thing Apple can do is put tons of patents (including shit ones) and then FUD everyone with their army of lawyers.

There was a post yesterday I think about someone implementing a similar algorithm with the SpaceXs one to vertical land a virtual rocket, see is possible to implement a similar looking thing without sending a commando of guys and steal tech.


A great example is the Chengdu J-20, which was a direct clone of the F-22 using plans stolen from Lockheed Martin. The J-31 is heavily inspired by but not a complete clone of the F-35 because the latter was still under heavy development when the plans were stolen. (https://www.justice.gov/opa/pr/chinese-national-who-conspire...)

The J-15 is a clone of the Russian Su-33, reverse engineered from a physical jet they obtained from Ukraine. The only real modifications are the use of lighter composite materials so that the inferior launchers on Chinese carriers could get them in the air. (https://nationalinterest.org/blog/buzz/high-cost-china-payin...)

These examples are all military because private companies are unwilling to publicize their designs were stolen, and the government is unwilling to admit they couldn't protect private industry.


There are instances of copying. That doesn't mean all successful technologies are copied. Some technologies are harder to independently develop. Supposedly advanced jet engines are really really hard, but space technology strangely less so, because of lower safety requirements.

In other words: for the claim "their space technology is stolen", more proof is needed. Just because they copied some other area is not enough proof to say they copied this area.


The burden of proof is not on a random person on the internet to investigate their space program. I can't prove the technology is stolen, just as much as you can't prove that it isn't. We are not nation-states and don't have the access or resources.

But a reasonable person can look at a pattern of behavior and extrapolate. If China in this case was a CS academic that had plagiarized a few papers, HN wouldn't be falling over themselves to give them the benefit of the doubt on their latest work.


Nobody is cloning outright. They are all improving. It it not like a copy-paste. More like a clipboard exploit.
