Tcp seems like a really bad protocol for this.

sure - choosing the right extracurricular activities if they don't cost too much, are available in Minnesota and can fit in between your 2 jobs.

Sure - choosing good majors is important, if your parents can afford your school.

Sure, hanging out with the right people is important. Too bad they don't live in Minnesota, and too bad you don't have access to them.

mixmax··on Michael Lewis and the parable of the lucky man taking the extra cookie (2017)
yes, it's important to choose the right country to be born in, the right affluent and wealthy parents, the right ethniticity and of course the right gender.
mixmax··on I drove the Tesla Model 3 and it's not 'mainstream'
ah yes, voice control....

In your tesla all you might have to do is say "left driver seat window down" and the window opens. If you only want it halfway down you will have to say "stop" at the right point.

Of course if your aunt borrows your car she will have no idea how to roll down the window because she doesn't know the proper voice control.

Of course it won't work when the window is open and you're driving fast because of the noise.

Of course you won't be able to remember all of the voice controls, and will inevitably end up screaming at your car to open the hood because you don't remember exactly which words to use.

Of course, before you go on your first ride you should read the manual and memorise all the voice controls.

Of course you should never say the words "open hood" while driving for obvious reasons.

Do you still think voice control is a great idea in a car?

mixmax··on Man charged after media storage site Dropbox finds child porn in his account
I remember a story where someone uploaded a large file known to be popular (a new torrented movie if I recall correctly) that would have a reasonably chance of already being in someone elses dropbox.

The file uploaded in an instant, lending a lot of credibility to the theory that the software hashes a file and looks for the same hash in a central database, and if there's a match doesn't bother to upload the file but simply adds a pointer to it.

mixmax··on To Protect Voting, Use Open-Source Software
In Denmark it was public who voted for what until around 100 years ago. In the first secret election where employers, landlords and other people in power couldn't see who their subordinates voted for the workers party got markedly more votes.

Think about it, it's easy for an employer to say that he will only employ people who voted for X, a landlord that will only take in tenants that voted for the right party, or even family members that will make sure that everyone votes along party lines.

There's a very good reason why voting is secret.

mixmax··on To Protect Voting, Use Open-Source Software
correct.

The problem with digital voting is that it needs to be anonymous who votes for what. That makes the problem much much harder.

mixmax··on Election Commission of India throws “open challenge” to hack voting machines
As Tom Scott points out in the video you're just moving the problem. They may not be connected to the Internet, but surely someone has programmed them. Who? And how do you know noone has changed the software? If they've been programmed at one point they can be programmed again.

It's Pandora's box.

mixmax··on Election Commission of India throws “open challenge” to hack voting machines
the vote-selling side effect is much larger than you'd like.

In Denmark someone made a study and found out that when voting changed from public (everyone could see who voted for who) to anonymous the workers parties gained votes to the tune of double digit percentages.

Presumably what happened before is that the landlords, owners and managers would tell the workers who it would be "best" to vote for if they'd like to keep their job or apartment. If I recall correctly this was around 1910 or so.

Yes, that's basically the findings of Thomas Pikkety. His tome "Capital in the 21st century" goes through great lengths to find and explain the numbers behind the finding.

mixmax··on Casting a vote online can be secure and convenient
current voting systems actually work very well with zero-trust.

- You enter into the voting booth with your ballot and cross off your preferred candidate or party. No trust needed.

- You fold it together and put it into a ballot box. No trust needed.

- The ballot box is sealed and driven to a counting station. This is done under supervision of all stakeholders, meaning that cheating is extremely hard because your political adversary is present.

- The ballot boxes are unsealed and the votes are counted. Note that the votes are counted by all stake holders (typically one or more people from each party) making it hard to cheat.

- The final vote is passed on.

None of the above steps require trust in any one person or entity, and the probability of cheating (if the procedure is done correctly) is quite low. If there is some anomaly the votes are saved so they can be counted again.

mixmax··on Why Google Wants to Sell Its Robots: Reality Is Hard
15 years ago it was rather hard....
mixmax··on Why Google Wants to Sell Its Robots: Reality Is Hard
"To develop robots, you have two options: You can either simulate an environment and robot with software and hope the results are accurate enough that you can load it into a machine and watch it walk."

This is much harder than you'd think.

Here's a fun story from 15 years ago when a friend of mine tried to do some simple AI:

His goal was to have a humanoid shape created is software learn how to walk using simple AI. The idea was that it would obey some basic laws (gravity, the limits of its joints, etc.), do something random, check whether or not it was closer to the goal of walking, tweak its parameters, and iterate. The chosen goal was not to fall over.

He set up the program, let it run over the weekend and let it do millions of tries. Hopefully when he came back to the office it would have learned how to walk, or at least stand up without falling.

His disappointment was huge when he came into the office: The simulated robot was sitting down with its knees bent, thus having achieved the goal of not falling over.

mixmax··on Peter Naur has died
ah yes, forgot that one. He also wrote the V8 javascript engine that powers chrome.

Other notable Danes include Poul henning Kamp that among many other things wrote the varnish cache and Lars and Jens Eilstrup Rasmussen that wrote the original google maps.

The Eilstrup Rasmussen brothers also invented Google wave, but I'm not sure how big an accomplishment that is :-)

mixmax··on Peter Naur has died
you're right of course. I thought I'd include it though since its so popular.
mixmax··on Peter Naur has died
It's interesting how many programming languages were made by Danes.

Nauer of course contributed to algol60, but did you know PHP was written by Rasmus Lerdorrf, Anders Hejlsberg developed delphi, turbo pascal and C#, Bjarne Stroustrup developed C++, Ruby on Rails was developed by DHH. All Danes.

Given a nation of 5 million people I think this is quite unusual.

mixmax··on When slaves and free men were shipwrecked together
It just so happens that over the last 2 winters I've been burning a scrapped wooden boat in my fire stove so I know how much fire you get out of a boat.

The boat in question was a 15 meter long oak on oak boat. It lasted 2 winters for 2 homes with a fire stove, and we didn't even burn it all.

There's an amazing amount of wood in a boat, particularly around the keel. The framing, keel and other structural elements are made of really heavy timber. On top of that good wooden boats are (were..) built of slowgrown oak that is incredibly dense. One large piece would last for 6-8 hours in my stove and give off a lot of heat.

It doesn't seem unlikely to me that a 25-30 meter boat would last for 15 years if you the goal was primarily to keep the fire going, only getting it really big/hot when needed.

mixmax··on Show HN: A high-tech floating Christmas tree with more than 2000 RGB LED's
interesting idea - and very much in the spirit of the project.

It's a pretty closed off harbour so there aren't really any waves, and there's almost no tide so not much flow past the raft either. Especially since it's moored in a sidechannel. So it probably won't work :-(

Kudos for the idea though.

no, but primarily from a "we already know this" point of view.
mixmax··on Show HN: A high-tech floating Christmas tree with more than 2000 RGB LED's
The obvious choice would be solar, except for the fact that at this time of year we only get around 6 hours of daylight in Copenhagen. Winter solstice was yesterday.

Wind might work, a windmill for boats might be able to give us the power needed. At least it would extend the battery time. Only problem with that is that they're quite expensive, and we didn't have much of a budget to begin with.

Maybe next year... There were so many things we'd like to have done, but didn't find the time and money for. One of them was an app or a dedicated webpage where you control the lights on the tree. Maybe even some kind of game where you play some game on the tree against other players.

Lots of possibilities, but limited time and money...

mixmax··on Show HN: A high-tech floating Christmas tree with more than 2000 RGB LED's
Thanks!

No, it wasn't coommissioned, but we got a 25.000 DKKR grant for making it. We spent it all on trees, barges and electronics, so noone made any money from it. But it was a really fun project.

It's a little light on details.

Is this related to the symphony framework in any way, or is it just a naming coincidence?

mixmax··on Under Pressure
I have some experience with dry ice in closed containers.

Every now and then some friends and I will get some dry ice, a bunch of plastic bottles and other containers with a screw-on lid and have a laugh making small explosions.

Basically you take a bottle, fill it 1/4 with water and 1/2 with dry ice and screw the cap on. You then have around a minute before it explodes.

A 1/2 liter coke bottle will make a nice whooompf and a 20 liter plastic gasoline can (the largest we have tried) will make a bang that can be heard maybe half a mile away. They very rarely sizzle out, and the ones that do probably have a defect, or we didn't get the cap screwed on properly. There's some time pressure, so you don't stand around checking before you throw the container. I would imagine that a metal container will make a pretty big bang (higher pressure before it ruptures) and may throw out some nasty debris.

It's good fun!
