Two9A··on Show HN: Dogecoin Average - the price of Doge
Apparently, a laser engraving of a Shiba Inu on the side of the craft would cost comparatively little.

I might donate a Doge or a few.

Two9A··on Show HN: Dogecoin Average - the price of Doge
Mm. I've followed the example of Bitcoin Average in this instance, who have a fixed 24h chart on the homepage. The backend can already cope with pulling data for a chart that's wider (or indeed, shorter) in timescale, so that may change when I've collated more data.
Two9A··on Show HN: Dogecoin Average - the price of Doge
Cryptsy, the crypto-currency exchange, have over a hundred markets running right now. Some of them are more active than others, of course.
Two9A··on Show HN: Dogecoin Average - the price of Doge
It does!

All the fiat currency values are calculated by taking the weighted averages in DOGE, and multiplying by the price of 1 BTC from BitcoinAverage.

Two9A··on Why is a minute divided into 60 seconds, an hour into 60 minutes?
"Decimal date and time" is probably the more proper phraseology. But that'd just be pedantry, of course.
Two9A··on Show HN: Bitcoin Target: A weekend project to understand targets and difficulty
There's no mining happening in the browser. My inspiration was CSI's "visual aids", where a computer will look like it's grinding through a database but not actually be doing any work.

So the red "random" hashes are exactly that: random numbers. The site just listens out for broadcasts on the Bitcoin network, and displays them when they show up.

Two9A··on TSA loudspeakers threaten travelers with arrest for joking about security
So let's say you didn't remember that off-hand, and had to search for it. What set of keywords would you use in your search, that wouldn't garner attention from certain authorities?
Two9A··on MongoDB Raises $150 Million at $1.2 Billion Valuation
Heh, do you work at my place?

We have the exact same issues with Mongo-specific queries. Even worse, our indexing regime (because we store relational data in Mongo) demands that we stick with Mongo 1.8, so all the comparative goodness of 2.x is lost.

And just this week, it was determined that there won't be any migration from Mongo to something-SQL in the near future, because it'd be too risky to attempt to translate a schema that's half foreign keys, half embedded JSON.

Two9A··on Ask HN: Freelancer? Seeking freelancer? (October 2013)
I don't know if you're doing this deliberately, but: your join form's modal is too large for my browser screen, and doesn't scroll.

Turning off position:fixed helps, but any resizes to the window just re-apply it. Thought you should know.

Two9A··on Ask HN: Who is hiring? (October 2013)
To be fair, that's about right for the UK market. Mid-range developer posts across the nation pay 30k, possibly a little higher in London.

It's low compared to the US, sure.

Two9A··on Stereogram Tetris
Yeah, I had a little trouble locking on to the well at first; I kept seeing the sides as pieces, and trying to move them.

Ended up alright though; score of 2080, and that's only because I lost vision after sneezing. This is a fun little concept.

Two9A··on Ask HN: Has the "Who's Hiring" thing worked out for anyone?
Worked for me. I applied because of a Who's Hiring post nigh on two years ago, and was hired. As an aside, I eventually ended up working on the same team as the guy who made the post.
Two9A··on My Father's "Eviscerated" work - Son of J.R.R. Tolkien finally speaks out
"More" respectful, perhaps, was what he was going for. I've found it can be very easy sometimes to get the meaning of a sentence entirely flipped between thinking it and writing it out.
Two9A··on X86/ARM Emulator
For the same reason I wrote DSemu and jsGB: an educational experience. I only half-expected to get an emulation to the state where it would emulate commercial games and/or professional demos; the main motivation was to understand how a system works by simulating it, and to gain experience at multiple levels of the architecture at once.

Writing a system emulator in JS/HTML5 is a great way to learn the system being emulated, how to quickly and efficiently read assembly and/or opcodes for the processor under emulation, and acts as an introduction to HTML5 with it.

Two9A··on After 35 years, Voyager nears edge of solar system
That's because there are many edges of the solar system.

The one you probably heard about was the termination shock, where the solar wind goes subsonic. I forget how far out that is, but it's closer than the heliopause.

From the graphs of radiation intensity, Voyager is either in a big bubble of interstellar space trapped in the heliopause, or actually through and out the other side. It's exciting either way.

Two9A··on AMA with Barack Obama
For 1, Reddit has a fuzzing algorithm on large vote counts, so voting bots don't know how much influence they're having. Refresh the page and you'd probably see a different number of up and down, but the same "net".
Two9A··on Why don't they just..?
Radiation, such as cosmic rays and solar flare output. The Earth has a magnetic field which pulls such charged radiation to the poles; Mars has much less of that effect.
Two9A··on First full-resolution images of the Martian surface
Remember that the images we have from Curiosity so far are from the navigational guidance cameras, though. The heavy equipment hasn't been fired up yet.

If I recall, the Mastcam will take a panoramic colour view later today, and that'll take a few days to download. Then we'll have a proper image, for the first time.

Two9A··on Mars Curiosity Operating System: VxWorks
I was watching the Planetfest rebroadcast of Curiosity's landing, and mention was made of there needing to be two operating systems: one to deal with entry and landing, and the other to handle roving and research. The speaker went on to say that both OSes don't fit into RAM at once, so they would have to be swapped over post-landing, and that this would take four days to load from Flash.

Raises the question: why does it take four days to swap an operating system in from Flash, and how does the system go about it while having a path to fall back?

Two9A··on Malbolge (programming language)
Esoteric languages are good fun, to be sure, but it's possible to take the concept a little far.

Brainfuck, for example, is a great example of a minimalist Turing-complete language, expressed as an esoteric. Befunge and Piet are other good examples of languages that approach programming from a different angle. Malbolge, though, is just malevolent and evil for its own sake.

I guess that's the point.

Two9A··on Steganography with Brainfuck
I wouldn't go so far as "snake oil", just "pointless fun". As mentioned elsewhere in these comments, the idea behind this was "what if I could run an image file as a Brainfuck program?"

It's not a rigorous academic study of the merits of Brainfuck as a steganographic technique.

Two9A··on Steganography with Brainfuck
Mm, sounds like a plan. In taking the 8-bit greyscale image down to 4-bit, I've essentially introduced a margin of error of +/- 8, which explains why the message was able to fit into just the first ten or so rows of a 128-row image.

A higher palette resolution would, as you say, increase the amount of space taken by the message, but would result in a higher fidelity of the image.

Two9A··on Steganography with Brainfuck
You make a fine point. Amended the intro.

The original idea that popped into my head was, "what if an image was a BF program?" With compression and/or palette reorganisation, of course more BF can be fit into an image, but it wouldn't be a pure BF program.

Two9A··on The $36 soda: Overdrafting in America
Would you happen to know which bank is doing that at the moment? In the last year, I've had a debit or credit card from NatWest, Halifax, Lloyds, Santander, MBNA and Barclays; never had an "incorrect PIN" charge though.

If it's a new policy at one of those, I guess I'm closing my account...

Two9A··on F.lux makes the color of your computer’s display adapt to the time of day
Yeah, it's not ideal for colour-sensitive graphic work like that. I'm a coder, so when I picked this up a few months ago it was wonderful.

The only issue I have is that it locks up the entire computer while it fades gamma down at sunset, and again at sunrise. Maybe that's intentional, to let you know that sunset's arrived?

Two9A··on It’s OK to make an extra $2k per month if you’re a programmer. Here’s how.
It's figures like this that make me think I'm not doing very well with my articles site.

0.02% CTR on 50k page views a month; revenue under $1. I guess that's the compromise you make when your niche is involved articles for a technical audience, but is there a way to improve that?

Two9A··on Ask HN: How much recurring income do you generate, and from what?
A question for you. I have a technical articles site, but I write something fresh around once a month, and my articles are massively long; would you recommend breaking them up and releasing parts more often?
Two9A··on (Android) Developer Income Report #9
$3-6k, you say? I've got a blog (well, an article site) that pulls in perhaps $5/month, so I'd love to know where and how you're getting traffic of that magnitude. Even $1k a month would be very welcome here ;)
Two9A··on Ask HN: Freelancer? Seeking freelancers? (April 2011)
Let's give this a blast.

SEEKING WORK - REMOTE

I'm a PHP/JS developer, with a background in the embedded field. You might know me from the DSemu and jsGB projects, building games console emulators in C++ and JavaScript respectively.

If you need PHP/MySQL/JS work done, I'm available on a remote-work basis. I'm also open to embedded C/assembly work, if you have any.

Two9A··on Non-blocking Programmers
This gets said a lot, by many people, but: by checking their open-source / publically available work.

If someone's managed to complete a significant task, and the code looks readable and reasonable, they're probably fair decent programmers. Even better if they've got code Out There in multiple languages; that shows a broad base of both knowledge and experience, in my opinion.
