Learnt is most commonly used in British English.

If I visit my in-laws house for a few days, which is a common occurrence, am I unable to watch my Netflix account on one of their TVs? It sounds like I would be restricted to only mobile devices.

Maybe it's one home at a time?

I absolutely keep my personal GitHub account separate from my work one for that reason. It's also because I like to keep my work life and personal life separate. That's why I don't use my work email for private matters (you never should anyway!) and I don't use my work PC for anything other than work. It keeps things clear cut for both my employee and myself.

It should read "then compares the generated hash to the hash that was received from the client to verify that it matches"

Or something along those lines.

I assume the reason for doing this is to confirm the symmetric key now in use is known between both parties?

I wrote it above, but more relevant here maybe: No. There's no need to confirm that, if the keys don't match everything will fail anyway and the connection aborts because everything either party sends appears to be gibberish.

The description linked over-simplifies, the hash they're calculating is a summary of the handshake process by which keys are agreed, we want to prove that both saw the _same_ process happen to reach this state.

Suppose I am willing to use archaic method A because I'm a simpleton, although I do know methods C and E which are safer. The wise people running www.google.com only allow method A if you don't know methods B, C, D or E.

Now, I try to connect to www.google.com and unknown to me a Bad Guy is in the middle. I say "Hello, I know methods A, C and E", but the bad guy changes that message to say "Hello, I know method A only". Google replies "OK I guess we can do method A then" and we use method A. The Bad Guy knows how to break method A and now my security is ruined!

But with this Finished message in TLS, www.google.com and I will calculate different hashes, since I know I said "I know methods A, C and E" but www.google.com got a message from me saying "I know method A only" and those don't hash the same.

This proves somebody is tampering with our connection, we must abort.

ah, cheers.

A little random but I thought some of you might want to know what the stores were that were next to the vending machines in the photos.

Pictures:

1. Alcohol and food store

2. No store

3. No store

4. Alcohol store

5. Eel restaurant

6. No store

7. Egg vending store (direct from farmer)

8. Rice polishing vending machine (turns brown rice in to white)

9. No store

10. Sightseeing ferry office/shop

11. Apple store (actually name of company but they import brand name products)

12. No store

That's obviously only a small sample but as someone who lives in Japan I can tell you that usually where there are alcohol stores, there are vending machines. Of course there are other places they are too, but in my experience, it's rare to find one without vending machines.

I've seen photos of people gathered around beer vending machines having a jolly time from before 24/7 convenience stores took over that particular market segment.

I live in Kyoto and was surprised to learn that there were even 18 convenience store robberies in the year before the program started. It's really safe here so I wonder what percentage of those armed robberies included assault on the clerk. Anyway, this is a good idea. And the Kyoto taxi drivers are amazing too. They aren't your standard "just arrive in the country and don't know where anything is" taxi drivers that are found in many cities. These guys usually own their own taxi and take great pride in knowing where and how to get to anywhere in Kyoto quickly and safely. If you are in Kyoto and take a taxi, you'll never have to worry about being taken the long way so they can get extra money. So good on them for working with the police in this situation.

Having lived in Japan, what surprised me was the implication that convenience stores have parking lots. Really? Don't think I ever saw one.

Many do, this one is in Tokyo, albeit not central Tokyo:

Note: HN will elide links that are excessively long, so next time you can just paste the Google Maps links directly. Plus a lot of people don't like clicking on blind links.

In the inaka they do.

I found that level of pride & care to be case for taxi's all over Japan, though I never took a taxi in Tokyo where it could well be different.

Thank you for your reply.

You are right in that I am a more practical, pragmatic programmer. I do have experience building enterprise applications and project management which is great, but I am lacking in the algorithm side. This is part of the reason why I am pursuing the degree.

Ultimately, I would ultimately like to do something with robotics/machine learning. I have a real passion for automation. I would love to work at a place like Amazon and help build the future of automated distribution. The algorithm side of things would tie all my skills together.

I will talk to the university about their statistics side of things of this course. I will see if I can get a full course outline and go from there. Would be more of a challenge, but worth it in the end.

Thank you again for your reply.

Robotics and machine learning are two entirely different beasts. If you want to go into machine learning, definitely opt-in for the statistics side. Machine learning is arguably more about statistics than about AI.

I liked the concept but I found the game had a couple of annoying issues.

1. The clickable area around the number needs to be a little bigger. I am using a HTC One M7 and it often wouldn't register the clicks.

2. After this first game, a full screen ad popped up and that really annoyed me. I don't mind the banner ads at the bottom, but full screen ads are VERY, VERY annoying.

Hi there!

1. Ok, thanks for the feedback. The annoying thing with Android is to be able to test on many devices, so thanks a lot for the feedback.

2. In principle you should only see a full screen ad every 4 games, not right after the first one. So apologies if this happened to you, again I'll investigate.

I'm also taking the N3 in a couple of weeks. 頑張れ！

Thanks! You too!
