>And if the test fails, then try to fit again. Run all night and in the morning, presto, have a model that does well on the test data. Now what have we? Not a trivial question to answer.

Minor quibble, but the proper way is to use validation data to find the best model and training parameters, the test data is only used once to test how well it actually works.

>A little like 'self driving cars': Really 'self-driving'? Nope, not close. Only on streets where everything has been mapped down to 1 cm or better including all the painted lines, all the curbs, all the traffic signs, and all the traffic lights, etc. In no way does the 'self driving car' actually look at a new street scene, make sense out of it, and use that 'learning' to drive. Instead, so far a self driving car is about as amazing as a train on a track.

That's not accurate. Self driving cars do take input and can't rely on a static map since the world changes and it has to detect obstacles and other cars. I'm not entirely certain but I don't believe they are using very much machine learning in current generation self-driving cars. However there is a startup working to make one with pure machine vision, and it was done once in the '90s with neural nets (ALVINN.)
Going back in time, when the person first started as an employee, the employer made a promise that the person would receive a pension upon retirement. That was part of the employment contract negotiation. People decided on a job based in part on the entire earnings, which includes both salary and pension. Some people are willing to take a lower salary in order to have a higher pension, while others prefer it the other way around.

If the state and cities are going bankrupt then why did they enter the contract in the first place? What was the economic planning they did which let them conclude - apparently falsely - that they would be able to keep their side of the bargain, and how has it broken down?

Personally, I believe it's a combination of continued pressure to lower taxes and continued pressure to outsource government work to more expensive private businesses, especially when tied to the philosophical idea that the government should be small enough to 'drown it in the bathtub.'

In other words, another solution to not going bankrupt is to raise taxes, rather than breaking existing contracts.
In California, I feel like 'increases property values' is not that valuable to cities due to prop 13. Big increases in property values serve to lock people into their current homes because they lose their property tax subsidy if they move.

Using <script async> you don't know how much of the DOM will have been constructed at the time it executes. Using an iframe you can choose to start loading the script early, but then specify the exact point at which it should be executed. E.g, after a certain div has been placed in the DOM or after the entire body has been constructed, etc. Also, <script async> doesn't work in IE9 or below.
Think of it as the distribution of illegal information that is illegal. And the idea of a "illegal number" is extremely misleading. Every number can represent any content under the right encoding. It's also nearly infinitely unlikely anyone would stumble across the data own their own by chance.
Great stuff! The race to build a map of the UK with trains moving around on it begins in 11 days.

I hope that we'll see an app for the UK with CityMapper levels of awesomeness soon, that would be rad. The National Rail apps built by the various train operators are missing some good stuff.
I learned Turbo Pascal in an MS-DOS emulator running on old green-screen Burroughs smart terminals, circa 1987. I knew the terminals had some sort of graphics capacity because their font changed when they left VMS mode and started emulating MS-DOS, so I wrote a program to rummage around in memory until I found where the font designs were stored. Then I wrote a font editor that changed the standard font whenever I logged in, to a design based on my own handwriting. After that, I took a leaf out of the Microbee computer's books and emulated hi-res graphics: I wrote a program that printed all the ASCII characters from 33 to 255 in a rectangle, set their font definitions to all zeroes, and then selectively set individual pixels back on according to a pattern that assumed the exact layout of characters. Implemented line, circle, flood fill and a few other graphics primitives. Fun!

I understand how SQL ties into what I want, but there are a few points you might have overlooked for what I wanted:

* Micro-optimizations. The implementations should be granular, not monolithic like SQL servers (let alone the fact that optimized SQL rarely translates between the implementations, as most optimization commands are not cross platform).

* Embeddable DSL, this one is honestly a problem with programming languages in general, but I've yet to see a static programming language which can tell me when my query is malformed at compile time (or hell, even provide decent syntax highlighting). Let alone importable, custom, extensions to SQL, or embedding lazy functions within the data structure.

* Intent vs Exact. The ability to describe partial intent, rather than exactly how to organize, the data (e.g. describing the operations expected to be executed across it, rather than the indexes to build). As well as having information available from the compiler about how the data structure is used (so that without the explicit declarations, the intent can still be optimized for).

SQL is a fine direction to approach the big picture problem from, but it isn't anywhere near the goal I care about. I'm not interested in dealing with big data. I'm just tired of having to know the difference between arcane implementation names for ordered sequences [1], I want to be able to describe what I want my ordered sequence to do, and let the compiler figure out the best implementation available.

Snuggle: Efficient Socialization and Ideological Critique on Wikipedia (pdf)
reasonable looking nitpicking can reduce any hero to a moronic chicken/looser. Kind of character assassination by "holier than thou" types. Heroes are humans and have their flaws too. They are heroes because they find the courage to take the stand, not because they are flawless. And these flaws are where the "holier than thou" sink their claws and teeth in. Kind of reminds about the "reasonable criticism" response HN offered to Aaron Schwarz back then.
I think we're still waiting for the "IBM PC Compatible" moment on the IoT. Most of whats available today reminds me of the C-64 era of computing. Everything is limited, silo-ed, and locked. Lots of gardens, no ecosystem.

There's a big difference between complexity being hidden from the user and complexity being locked away in a portal, platform, or single service.
God, I wasn't nitpicking -- I even said my comment was off-topic. I was throwing advice into the void, for the author if they read it or the commenters here.

And it's fairly important stuff for me on a regular basis. At work we generate hundreds of gigs of logs daily, and doing things in the right order with tail and grep etc is often the difference between a script working or not, or between it taking seconds and taking minutes.

Abstract:

> ``Wikipedia, the encyclopedia "anyone can edit", has become increasingly less so. Recent academic research and popular discourse illustrates the often aggressive ways newcomers are treated by veteran Wikipedians. These are complex sociotechnical issues, bound up in infrastructures based on problematic ideologies. In response, we worked with a coalition of Wikipedians to design, develop, and deploy Snuggle, a new user interface that served two critical functions: making the work of newcomer socialization more effective, and bringing visibility to instances in which Wikipedians' current practice of gatekeeping socialization breaks down. Snuggle supports positive socialization by helping mentors quickly find newcomers whose good-faith mistakes were reverted as damage. Snuggle also supports ideological critique and reflection by bringing visibility to the consequences of viewing newcomers through a lens of suspiciousness.''

Guys, guys, I hate to break this to you, but I think Forbes picked an example that may not be representative of the typical government pension.

I'm not saying that I disagree with the North County Times of Carlsbad, California, but I think that most government pensions are not that generous. $30K/year is more likely, and those employees may not be entitled to Social Security benefits either.

Easy Android Custom View Reuse in Eclipse
They are, but they're not included in various browsers for various reasons -- so they are "legit", but they are not easy to use for use-cases where you don't have a modicum of control over clients (can install, or ask clients to install, cacert root keys).

Please don't suggest that cacert is much less secure than trusting a handful of government CAs by default (or even much less secure than certain commercial CAs).

Cacert isn't perfect, but it is an interesting and important project. It's a pity Debian ended up stripping cacert IMNHO. Anyway, it is healthy to be sceptical, for some more info, see eg:

Swiss Army Knife Syndrome
I agree that the IoT should be about improving lives but that's true of any new product/service/thing and is not specific to IoT.

I do think the post misses the much larger point of how such services and products get created and deployed. Right now, developers either have to (1) use someone else's platform and be locked in or (2) build a system completely from scratch.

We've already seen what happens with option 1 on the web, where the company providing the platform can make an arbitrary decision that puts you out of business - or they get acquired and shut down or a whole host of other things. Option 2 is just too difficult right now unless you're doing nothing but 'appccessories' (toy devices that have some networked functionality) - mainly because we're dealing with distributed systems and the problems they pose.

What's needed are open-source tools to make option 2 viable for a new wave of developers. In other words, we need the equivalent of the open-source LAMP stack but for distributed systems. Just think for a moment of the billions of dollars of value that this open toolstack enabled. We need an equivalent stack to solve the modern problems and empower developers to make new products and services.

I see these modern problems as related to (1) how we create and deploy applications, (2) how those applications store and sync their data and (3) how they identify and securely connect to each other. Of course, there are solutions to all of these right now but they're cumbersome and inappropriate for the environment we're deploying to. I'm working on a toolstack that deals with these issues but in a much more scalable and resilient way. We're calling it the MISO stack and I'll be writing more about it soon. In the meantime, you can look at following post to get an idea of what we're doing and why.

Some sort of colour swap could indeed be helpful, an interesting idea. In my own personal experience, though, whole ranges of colours can be confusing - for me, red, orange, green, brown can all together be problematic. And more so in some shades than others. Different colour blind people experience difference types and severities.

I think we are talking about two - both good - ideas. I was thinking a "show people with working vision what stuff looks like to the colour deficient" - e.g. toggled by the press of a button. Sounds like you're thinking of a "colour management thing to help colour blind people actively change their experience". That too could be awesome, although one down side is possibly: for all that my vision is deficient, it's normal now to me, and any permanent screen filter would be very strange to work with.

As far as games go, the best mechanism seems one which requires no colour vision at all: i.e. if you can still play it in black and white (TV / monitor settings), then it's 100% friendly to the colour blind. Things like textures, symbols, shapes, contrast, and blinking can all be useful when done judiciously.

Of course - colour blindness is not the same as no-colour-perception. Explaining to friends and family that I don't see black and white has been a theme for me for 30+ years now :-)
Computer and Video Games online magazine facing closure
>Kinda of violates the whole spirit of the game.

I would say the spirit of the game is a competition based on vocabulary. Surely memorising character sequences with no understanding is completely against that ideal?

I agree however, that requiring an exact definition would be a bad way to do it. The point is to understand, not to memorise, so they should only need to give an approximate definition. For casual games, I think agreement of the players is fine, and for competitive play, you can have a judge to decide if their definition is close enough.

Agreed - one design that works for everyone would be best. All it takes is a little up front awareness and I don't think there's all that much aesthetic compromise to pay.
Are these exceedingly simple programs 10 line programs? Otherwise:

How do you know they compile?

How do you know they work?

How do you know they handle all the edge cases you can throw at them.

If you have a 100% accurate parser and compiler in your head, I am impressed.

Our teachers (and this was 15 years ago) had test-runners which would compile and run our programs to make sure they met the requirements of the homework THEN they looked at the code and marked it for style etc.

Sometimes they provided these test runners to us so we could check them ourselves, sometimes they didn't (this was, naturally, harder).

As for the look. That's personal I guess. We'll keep improving it though to make it more universal.

The underlying problem is the loading of the CSS is blocking (blocks DOM as well).

However, that problem is complex to workaround.

Using the async flag doesn't fix that problem, and the async flag also means that you need to make sure your scripts can run in any order (which will cause problems unless you are very careful e.g. use a loader that manages dependencies asynchronously).
