The BBC 'B' (32k memory) light would be the BBC 'A' (16k memory)

The Electron was the machine Acorn had already built before they got the BBC contract.

Programs for the Electron were transmitted via Teletext on BBC before the BBC was around. 12 year old me transcribed them by hand and read the source code to try and learn programming while my BBC was on back order (little knowing it was tokenized!).

My BBC still sits here in the room with me, I still use it occasionally for fun.

Yours is just trolling.
Personally, I believe there is more diversity of opinion on political topics than behavior exhibited in the comment threads on political topics.
As a Saudi HNer who has spent his life between Saudi and the US, I hope I can point out a few things here. I understand the point the author is trying to make. It does, however, come off to me as unnecessarily hostile and overreaching.

- Saudi Arabia has 18 million nationals. The vast majority of which are sunni salafis (the nomenclature preferred to "Wahhabism"). If Wahhabism was driving motivation for ISIS, then ISIS would have been at least 1000 times the size it is now. Which is clearly not the case.

- While ISIS has similar sounding rhetoric to some hardcore Saudi hardliners, it is almost uniformly reviled and regarded by almost everbody in Saudi as an extreme perversion. And not only since they blew up a number of mosques in the country (or since releasing that video of a Saudi ISIS member executing his own cousin who lay begging for mercy in the begining of that fateful video). But their gruesomeness is as repulsive to Saudis as it is to everbody else in the world. And they are seen as one of the biggest obstacles to the ouster of Bashar Al Assad in Syria (who is responsible for a civil war that has killed more than 200,000 people, mostly Sunni).

- The article makes little effort to distinguish between the Saudi people and the Saudi government. It demonizes the saudi populace even though it is at times the first victim of some of the unsavory consequences of the alliance between the monarchy and the "clergy" (a rather inaccurate term since there is no real hierarchy. The closest thing there is a counsel of elder scholars and those are usually selected for being unwaveringly loyal to the government). There is a subtlty to the dynamic of the populace, monarchy, and clergy that few in the west try to understand. I can expand on this later.

- None of this is to deny the existence of an activist, xenophobic, hateful, Quran-thumping segment that is a loud ultra-minority from which Alqaeda and ISIS try to recruit (with Saudi being one of the first places they often like to target). The government have clamped down HARD on the vast majority of this segment ever since the string of terrorist bombings in Riyadh in the early 2000s.

- Like I try to explain Saudi here, I often try to explain the US to people in Saudi. If there's anything you'd like me to clarify about Saudi, AMA.
Most medical plans create doctor pools and aggressively recruit doctors for those pools. I've never found a doctor that didn't accept my insurance.

I stumbled upon the channel by mistake once. What I found to be really interesting was the reactions flooding in the chat. You could, for example, like the author said, see 'gg' appearing in mass at the end of a painting, but not only! There was a beautiful moment where Bob decided to use a large brush and applied brown in a vertical band on the left side of an almost completed canvas ; you could instantly see the 'RUINED' and crying emoticons spawning in the chat. Then, he went on reassuring the audience and starting to add details, so the large band was gently becoming a tree ; he made a very kind comment and this instantly triggered a wave of hearts emoticons.

It was very strange to witness the involvement of thousands of people through the chat of an online streaming platform, and I think it was a lot like watching a pet asking for food. Or something like that.
Ask HN: Good book to learn about data structures, algorithms, Big O notation?
Hey HNers, any good book or material to learn about data structures, algorithms, big O notation, trade offs and etc?

My focus is on biotech :) but what about Thermofisher working on their Ion Torrent platform (although this isn't a startup). They use ISFETs for DNA sequencing.

Health consumers are rarely the customers, though; providers' customers are actually the carriers, and the customers make the market in healthcare. The asymmetry in price signaling between patients and carriers causes, as you point out, weird distortions in the market. (It doesn't help that price transparency for patients is basically zero.)

I like how Swift does it. There are no real exceptions, but error object handling to jump to the end is fairly easy. It reduces boilerplate and increases readability.

do {
try error-return-statement
statement
statement
try error-return-statement
} catch ErrorType1 {
...
} catch ErrorType2 {
...
}

It looks like exceptions, but under the hood error objects are being returned by error-return-statements, thus the explicit try keywords before them. It retains go error object simplicity, but keeps things readable and tidy.
I don't have twitter, so I'll just leave this here: perhaps it'd be fun to graph the time delay between RUINED and SAVED?

Yes, so the one I am most familiar with is Tendermint (disclaimer, I'm friends with some of the people involved). This is a genuinely novel consensus protocol that is inspired by DLS and PBFT (classic Byzantine consensus stuff), and also runs smart contracts using the same languages as Ethereum. Ethereum themselves are trying to do something similar (Casper), but to the best of my knowledge it is not ready yet.

Not sure what your math is, but mine is about 20% larger rocket to get to 160KM and have enough speed for orbit, at least as far as cube-sats that can skip on the atmosphere for a bit go.
There's also https://en.wikipedia.org/wiki/Copenhagen_Suborbitals with their plans for a manned suborbital flight, their rocket (although it blew up) could also be used as a base for amateur orbital flights.
I'm not entirely sure what is so surprising here, it's a question of money at this point, but amateur rockets are quick close to being able to reach space, this doesn't mean that they will be commercial viable or even viable for any non-anecdotal use.

I ran into a former coworker from LivingSocial last week. We talked about how they had quite an impressive stable of Ruby developers a few years ago. Many have left, but there's still several who have been there for four or five years. I can't see why so many great developers are still there. Comfort in the knowledge that they could get get another job in a heartbeat if they needed to?

It's in fact an article on how to do software versioning "properly", which we kind of know...

The true problem is vaguely defined APIs with vaguely defined behaviors which are prone to change/be fixed/be upgraded during minor updates, which do not qualify as "breaking", because no one realises they do break compatibility.

So it's not so much about fixing your version numbers, it's about fixing your tests and specs. And only then you might be able to use the right versioning...

The more formal education you go through, the more you realise that formal education isn't something magic. It's a framework which provides a thought out curriculum and a system of motivation to learn (otherwise known as exams).

The first one is, more and more, being addressed by MOOCs and Open Courseware type websites. The second one is the real stickler. Motivation without someone external providing a push is really hard, and not something the majority of people can do.

Whether that motivation is really worth the ludicrous 6 figure fees of most law schools is another question entirely.
No.

The US been in recovery since 2010. First to recover was corporate profits thanks to downsizing and low interest rates. Consequently, the S&P went on a tear [2010-2014]. With corporate profits recovering, companies could start re-hiring and unemployment dropped [2010-2015][0]. Now that employment is back in healthy territory and the stock market is back where it should be, Americans are feeling a positive wealth effect, so next to recover is real estate. Still juiced by low interest rates, real estate prices will continue to rise significantly in the [2014-2016] period.[1]

I'd be on the lookout for a recession once this real estate cycle plays out, maybe in the [2017-2019] time frame. By then, interest rates should return to the low end of their historic range [2].

I've read many startup/management books the last few years and I keep going back to High Output Management [1]. Andy Grove has really great insights about managerial leverage, influence, planning, the purpose of and how to hold meetings, and motivation vs. control. His perspective on one-on-ones has been especially useful as we scale.

[1] If you don't have time to read the whole book, I've taken some pretty detailed notes at http://charles.io/high-output-management/ :)

I'm building with Angularjs and Express right now coming from a Drupal experience. At every turn I'm looking to Drupal and Drupal contributed modules to solve problems, for example, media asset management. If I had to to solve for internationalization, document versioning control, publishing workflow, publishing workflow with versioning control (lol), integration with a full-text search engine, micro data markup, and several other common problems, I would start with Drupal which also provides a fully functioning REST server that integrates with all these things seamlessly. That is the miraculous part, the seamless integration. It is plug and play, but sometimes I have to open up the insides and write 'glue code' to bridge the different components. Also, I have to export configuration from the database into code which is possible. I'm talking Drupal 7. Can't wait till I get a Drupal 8 project.
China pursues fraudsters in science publishing
Maybe my reading comprehension isn't so sharp today, but I found this article difficult to parse. So I looked at the disclosed set of documents.

Basically, the series of documents are NSA OIG and Congressional reports about the email surveillance program that was shuttered in 2011. It provides a bit more information than was previously available under the original leaks in 2013.

What the author of this article is trying to express is the idea that the NSA was able to resume the function of the email metadata program (they call it PR/TT, or Pen Register / Tap Trace) with some other secret program. The NYT alleges that a paragraph on page 65 links this defunct program with the upstream collection and the PRISM (both FAA §702) programs. It's stated in the paragraph that the NSA concludes that it can do its job with upstream/PRISM and for phone calls, chaining through the telephony metadata collection (SPCMA).

TL;DR: The NSA stopped using the email metadata program and then relied on upstream/PRISM and the telephone metadata program to fulfill the need. The NYT got some FOIA'd documents to confirm this with an official statement.
Honestly, that's pretty naive when we're talking about biology and complex ecosystems.

Yes, there are a lot of unknown unknowns, as you stated. So, not quite sure how you're concluding it's all good.

I disagree, sort of, a little bit.

If I'm writing a shell pipeline for data analysis, I rewrite it as a Makefile. Make is a great tool for this sort of thing.

I'm not sure many people are arguing that abstraction isn't good for those who are writing the code--that's the whole point of abstraction after all, to make the developer's job easier.

The problems tend to crop up for other people trying to decipher and read it. Sometimes also for the machine trying to execute it.
> These are people who are very likely at the top of their fields, have gone through rigorous (and costly) training, and are going up to do very specific jobs

That is irrelevant to the level safety precautions. Unless you were trying to argue that their costly training makes them worth more than other people. I hope that is not what you were arguing.

> doesn't mean we shouldn't be doing everything we can to ensure a safe flight

At some point you have to declare something 'safe enough' since 100% safety is an impossible perfection. Bicycles aren't 100% safe, but we don't go around insisting on multiple backup systems. Personally I do find it curious that the standard of safety for astronauts is so high. The cynic in me suggests its less out of concern for the astronauts and more to do with the publicity fallout that occurs after disasters and the damage to other assets. The optimist suggests its more a concern for all the ground crew and spectators who are also at risk. There is potential for a lot more than 4 casualties when you play with that much fire.

The city of Amsterdam has created a 'meldpunt' for issues with short term stay residents (such as AirBNB guests), they probably did this because they have an excess of funds and need to spend that money somehow.

I'm kind of surprised that you think that there is no impact from having an AirBNB hostel in your apartment, you probably have no idea what a typical Amsterdam-centrum house look like but you should probably believe me that coming-and-going is something that you'd most definitely notice and a party in one of those old houses might as well happen in your house.

Hotel guests on average do not behave like residents, they're on a holiday after all and are out to have some fun. In Amsterdam that usually translates into going out, doing drugs and visiting the red light district. Elderly ladies and tourgroups tend to stay in hotels.

Don't get me wrong, I'm fine with people renting out their single-family home in whatever way they see fit but when your next door neighbor is a paper wall away you can't just set up a hotel in the same building without taking some pretty good measures that there won't be any negative impact for the other residents.
I think the Tabata airbag fiasco is an exception.
So I thought that the article was misleading in that it attempts to link an email metadata program which applied to all email communication, including U.S. persons with two different programs (upstream and PRISM) which only authorize collection of targets that are not U.S. persons and are outside of the U.S., and have a valid foreign intelligence purpose.

It's certainly possible that the NSA simply disregards the laws and collects on everybody. However, there isn't any evidence of that here.

Kudos on the NYT for winning their lawsuit and getting the documents through FOIA, though.
Not sure what that means. If a ship is burned to ashes, then is it still a ship?

If those ashes are then mixed with other substances to form construction material from which a home is built, is it still a ship?

If wood from a forest is never assembled into a ship, is it still a ship?

State and identity seem intrinsically linked.
> Today, LivingSocial is more unicorpse than unicorn.

I like the ring of "unicorpse", hopefully it becomes out go-to word to describe the upcoming batch of startup failures.

Plus, I would imagine that the contacts list is going to be the most efficient way to store and retrieve that data. It's in a database, just like anyone else's is, right?
I am saying three things:

1.) There is a very common assumptions in the USA that because a State funds healthcare, the individual is not allowed choice of doctor, which is incorrect in every public healthcare system I have used.

2.) That public or state run health care system is not substandard or less efficient to the American private system, but actually generally better for just about everyone.

3.) That if every American paid a flat 18% tax for healthcare (instead of any healthcare insurance premiums, whether paid directly by you, or by your employer), then the American government nationalised all American healthcare, every American should then receive at least a $4000 tax rebate. Then again your government could use that money fund better schools and universities.

[EDIT] And by-the-way, the UK Government still spends less than the American Government on every citizen, on healthcare. The American government spends $4437 per every single American citizen every year on healthcare. By contrast, the UK spends $2919 per person, every year. You tell me which tax payer is getting better value for money.
