So, it seems that not only does McDonalds in Paris have some strange issues with cameras, but judging from these comments, a surprising number of French people are racist.
Surprising?
One episode of the British comedy drama series "The Inbetweeners" involves French visitors as part of a school exchange programme. The protagonist's guest is mainly moody and silent, but at one point, he says, out of the blue, "ah do not like Arabs". It's funny because many British people have had exactly that experience with French school exchanges.
Before you run too far with this, most kids will need more than $25 to get started. A monitor, keyboard etc. or a separate PC to ssh from. It all adds up.
True, but they Pi team observed that there's loads of keyboards and mice going to landfill. For a display, there's composite to an old TV (sounds awful, but we managed in the 80s/90s) HDMI to a new TV, or get a dedicated monitor. It *is* a shame the Pi has no analogue VGA for all the CRT VGA monitors going begging.
$500 school computer: "Right kids, it's 3 to a keyboard for the duration of a lesson. You can sign up for access during after-school club. Don't break anything because the next lesson needs the computers too. We won't have the PC lab next week because Mr Jones' class wants to take a turn.
$500 home computer: "Don't break it, Mummy wants to use Facebook after you've gone to bed"
$25 board: The PTA has signed up a sponsor so every pupil gets their own.
Also the Pi is designed for really simple recovery. Flash a new SD card and start again with a clean slate.
I assume lists and variables were left out as a demonstration of how you can build different interfaces for different purposes. If you were designing a programming course, you could introduce block types as you introduced concepts.
After some playing around, i had a script that could solve the maze with
Same algorithm I came up with. Well done.
assuming i was given an api with functions like turn(), wall(), and move() and they took those constants it would be a hell of a lot easier just to type what i typed there than to navigate menus and drag things all over the place. maybe it's inviting to non programmers, but sooner or later they are going to realize that the punctuation isn't what's hard about programming, it's the logic.
That "sooner or later" is what it's all about. The jigsaw interface lets the beginner play with logic and control with literally no opportunity for a syntax error.
Later, they export to JS/Python/Dart and can see how the exported text corresponds to their shapes. If they're at all curious, they try modifying and running the text version of the code.
That's when they realise that they can be more productive if they just hack at the text -- and that the tradeoff (having to get syntax right) is worth it.
But dealing with syntax when you've never coded before is a big hurdle. Why not remove it?
You know what would be a good test for this? You should be able to write a program (any program) in regular text mode, then import it into a visual editor and edit it there, and then re-export it into regular text and have it still be legible. If a visual editor can do that, it's as good as any other IDE.
No, that's not the aim. The lead dev wouldn't do his real coding with jigsaw pieces. It's an educational tool. You can export to JS/Dart/Python and that's good for two reasons:
1. The learner can see how their jigsaw pieces translate into text 2. The learner can take that text and use it as the starting point for something bigger
The real point of this is that you can get started without learning syntax. Most of us don't remember how hard we found syntax when we got started, but it's a real issue for many beginners. Watching your logic working is the satisfying part of coding. You never get that satisfaction if your problems satisfying the compiler make you give up in frustration. Yes, you need to learn to produce syntactically valid code -- but save that battle for later.
This is one reason I think syntax-light languages such as Logo and Forth are actually very good teaching languages.
I find explicit block markers to be useful when searching for the beginning and end of a long block. This applies whether the markers are THEN, ELSE, and ENDIF or { and }.
1. Surely finding the beginning/end of an intent-delimited block is something that an editor could do just as easily, if only it was coded. 2. Encouraging shorter blocks is good language design.
Clojure basically fixes that. LISP (unless you want to be *really* pedantic about differences), with all the libraries Java has.
Will it become mainstream? I can't see it. Whether it's rational or not, people seem to fear the parentheses, and have difficulty with the functional paradigm.
Key example: Try converting an array manipulation algorithm to efficient Erlang. It flat out can't be done: Erlang has no good syntax for indexed access of it's lists, forcing you to do a tail-recursive iteration counting through the list elements to get to the one you want. (This fundamental flaw killed the last project I worked on, so it's a pet peeve of an example.)
I have no Erlang experience, but I have experience in other functional languages. A quick Google suggests you should probably have used the 'array' module: http://www.erlang.org/doc/man/array.html
It doesn't matter what language you're using, you can't make a linked list (for that is what an Erlang list is) have the same performance characteristics as an array. It's not a fundamental flaw. You just refused to adopt the language's core paradigm.
Brilliant insight there, leading 4 people to moderate you "insightful"... You could have saved those researchers a whole lot of work.
Ever heard of "five whys"?
1. Why is a programming language successful? - Because programmers use it, or don't. 2. Why do programmers use it? - Because it does what they want. 3. What do programmers want from a language? -.....
Less than 3 why's in, we've already reached a question that you can't glibly answer. Or if you can, go ahead and release your perfect language.
"condos and restaurants...Except for MakerBot Industries"
Nope...you know, aside from three operating breweries, and hundreds of machine shops that dot my neighborhood. Or the medical instruments manufacturers, or the concrete and cement factories, or the furniture companies...
Well exactly. Brooklyn has a population of 2.5 million. The idea of it having no industry except restaurants is patently ridiculous. The idea of it being homogeneous in character is ridiculous. Brooklyn is much bigger than Manahattan, and even people with very limited knowledge of New York have an idea of the different characters of different parts of Manhattan (from film, literature etc.)
I would actually say there's a lot to be said for a head of state that has little power. Otherwise you get tossers like Blair being able to actually veto laws they don't like instead of being beholden to the public.
Why do you assume that the republican replacement for the monarch would have any power?
I think we should have an elected person in charge of shaking hands, cutting ribbons, smiling and waving. We should pay them a similar salary to an MP, and not support their entire extended family.
Not to disagree -- the queen does have very little say in this -- but in absolute pedantic fact, the monarchy has all the power.
God chooses the monarch. The monarch chooses a government -- it happens that nowadays she uses an election to choose. The government handles the details of running the country for the monarch. This is why it's called "Her Majesty's Government". This is why the Queen opens parliament. This is why the newly elected prime minister has to go to the queen and ask her permission to form a government.
Now, for all practical purposes, the monarch can't openly pull rank on the government -- because the monarchy only survives by public consent, and I think even the most strident modern monarchist would change their tune if the queen started dictating.
The evidence is the number of tourists outside Buckingham Palace and the like.
You would have to demonstrate that those tourists wouldn't go to Buckingham Palace if its resident was no longer the head of state.
The building would remain, just as hundreds of "heritage" buildings do. It might even become more accessible to the public.
If it's deemed that rituals like the Changing Of The Guard brings in tourists worth more than the cost of the exercise, then they could continue, no problem.
As if to demonstrate the principle, the Tower Of London is maintained by a non-subsidised organisation, paid for by donations, sponsorship and the tourists who pay to visit (and use the gift shop, cafe etc.).
So essentially you don't believe in democracy? Assuming a progressive voting system (and yes, I know that's a big ask), the country gets the president it wants.
In any case, presumably if one were to replace the UK monarch with an elected head of state, that elected figure would have an equally ceremonial role -- cutting ribbons, greeting foreign dignitaries, waving at tourists and so on.
Well, it could instead finance 15,000 public sector workers (at a rather generous £40K each) at a time when we're busily freezing salaries and cutting pensions, while gnashing and wailing about unemployment figures...
A comedian (probably either Mark Steel or Jeremy Hardy I reckon) counters the 'good for tourism' argument by picturing a foreign tourist in Paris, admiring the view from the Eiffel Tower -- "It's a nice view, but I can only feel it would be improved by there being an unelected head of state".

Bradford.
In the 2001 census: 26.1% Asian -- the only places in Britain with a higher percentage of Asians are Leicester and Tower Hamlets.
The same census says 69.3% white.
It was racist even to bring race up.
Here's a person who, upon hearing about a crime, thought "Oh, I know, I'd better post about what race they're likely to be."
So, it seems that not only does McDonalds in Paris have some strange issues with cameras, but judging from these comments, a surprising number of French people are racist.

Don't get confused, I am not being racist
Yes you are.
That's why the Raspberry Pi is part of an ecosystem including stuff like Code Club,

If you get your password wrong, you can't try again for 1 second. Every failure doubles the time required to try again.
Why doesn't everyone do that?
It doesn't help if your attacker has got hold of the list of hashes.
1. Steal hashes
2. Brute-force on your own system/cloud/botnet/whatever
3. Use password
The default in Debian is sha512.
Confirm by looking in /etc/pam.d/common-password
password [success=1 default=ignore] pam_unix.so obscure sha512
'obscure' enables those annoying checks on password quality. 'sha512' is the hash type.

A 1% majority (at least informally) means that the winner is 1% greater than the loser.
That is, the majority has 100%/2.01 and the minority is 100%/1.99.
51% is a slight majority. 99% is a vast majority.

Sounds like you're already a republican. The whole principle of monarchy is that the succession is decided by birth.
It is, indeed, up for debate: the pressure group Republic refutes the claim. http://www.republic.org.uk/What%20we%20want/Win%20the%20argument/index.php
