mSparks··on Amazon States Language – A JSON-based language to describe state machines
wait, what..!!

is that entire system state to state or per state?

i.e. if i have 100 states each transitioning 365 times bootstrapped a thousand times

they'll charge nearly a million dollars or nearly a thousand?

noting that takes like a minute on my desktop.

mSparks··on Amazon States Language – A JSON-based language to describe state machines
competely agree.

its one thing to serialise your states to json. quite another to try and recreate javascript or any other low permission language in it.

I know _why_ they did it, and i bet a fair few pure managerial types fall for the bait and commission a project or thousand on it, locking themselves in to amazons absurd pricing model for production systems. But everyones got to make a buck eh.

mSparks··on A security update for the Raspberry Pi
Yeah, and we definitely shouldn't be training the kids & other "normals" about security..... :|

HHHrrrmpf.

mSparks··on A security update for the Raspberry Pi
...and then deletes the file.

-> or just get angry when they reboot and cant get back in without unplugging it from whatever remote location it was plugged into and taking it home to plug into a keyboard mouse and monitor.

great for the effort. i did baulk when i first started a pi to find the defaults were so insecure. But I'm not sure the solutions are that helpful. cant we just set a root password on first boot like every other nix distro.

And they would be interested in signal processing a 50kHz LF radio transmission why?
mSparks··on HiFive1: A RISC-V-based, Open-Source, Arduino-Compatible Development Kit
Sigh,

Firstly, getting from uncompressed at the input to compressed is basic processing.

Seriously, you don't. Non risk instructions often take Multiple cycles, so you can only do a tiny number of them between samples, usually just enough to compress it to fit the bus speed without loss. https://en.m.wikipedia.org/wiki/Cycles_per_instruction

Thirdly, clearly you didn't rtfa.

Fourthly, go disagree on the teensy forum. https://forum.pjrc.com/threads/27364-Teensy-3-1-and-ADC-FIR-...

mSparks··on HiFive1: A RISC-V-based, Open-Source, Arduino-Compatible Development Kit
Depends what you mean by "enough".

24MHz is "enough" for 20 bits@96kHz ADC and some post processing.

But 20 bits@96kHz is not decent.

For reasonable SNR, you need at least 24 bits, and even then "the experts" offload to an external CPU http://www.tested.com/tech/pcs/454839-tested-why-high-end-pc...

For signal (less audio are more "controller") with high precision you need micro controllers with the power of at least an early 2000s PC (several hundred MHz and single cycle mul/div).

Raspberry Pi 3 is close, but it needs an external ADC/DAC.

mSparks··on HiFive1: A RISC-V-based, Open-Source, Arduino-Compatible Development Kit
72/120MHz isn't really enough to do "decent" audio/signal processing with low distortion.

You can probably get it to work with a lot of effort and optimisation, but there'll be very little room to do anything with it afterwards.

Afaik AC97 chips run at around 24MHz, are dedicated to the job, and even they stop at 20 bit resolution and sticking the data onto a data bus. Getting better than that is "hard", which is why all the manufacturers pretty much standardised around such a low standard.

mSparks··on HiFive1: A RISC-V-based, Open-Source, Arduino-Compatible Development Kit
That sounds like these boards are getting to the point they can handle decent audio/signal throughput. But I don't see anything about usb or adc/dac on the site?

I actually think its a great model.

easy to deploy, easy to clean up afterwards. exactly how "Cloud" should be.

Vivaldi browser?

Although thats still bugged to i believe.

mSparks··on Windows 10 informs Chrome and Firefox users that Edge is ‘safer’
This story led me back to test edge after a long wait for them to fix a million things.

It seems they fixed a million things, and I got me a new default browser.

Not sure how long it will last.

But I've been on bing since the last time I got downvoted for complaining about google search. at least trying to copy the search link for http://www.thesaurus.com/browse/help doesn't result in: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&c...

mSparks··on Android user locked out of Google after moving cities
mostly google employees reading hn these days would be my guess.

anything that suggests google isnt and never was the "do no evil" company and is rather just another pyschopathic corporate machine will just attract the wrath of said psychopathic corporate machine.

mSparks··on Why does it take so long for us to form our first memory?
finished electronic engineering in 98, just as all the sensible engineers f'd off to south korea and china.

2007 was the second time round.

around the time of

and

its now valuable enough capital that i dont technically have to work anymore and can spend my time flying helicopters and enjoying luxury yachts.

Although life isnt exactly that simplistic. It does give me some pleasure to know for certain the outcome was the us and uk loosing the world leadership.

And now you got Trump and May as your top representatives.

mSparks··on Why does it take so long for us to form our first memory?
Yeah I saw, rogue c&p in the "hide it from most of the internet" script.

It's an old site migrated from my first machinations back in the early 2000s.

And I make no claim to "absolutely authority".

But take your pick which "expert" you want to listen to.

The experts rolled out by the "love thee blue blooded leader appointed appointed by god" channel.

Or some random guy on the internet who likes downvotes and says he's been doing it so long it now pays for him to do this every other day.

mSparks··on Why does it take so long for us to form our first memory?
i have been building such stuff for the last 20 years.

even had stuff stolen by darpa. which is why i dont share much now.

mSparks··on Why does it take so long for us to form our first memory?
no, i loath the "experts" rolled out by the bbc as experts.

that memory is something we learn is not a new thing (technicallly the skill of forgetting, which is where autism comes from), the second post even pointed out synaptic pruning.

its not just known to be a learnt skill, we know the exact biologic process by which it manifests itself.

the "experts" are the ones building the ai that will take all your jobs. and you wont find them giving interviews on the beeg.

mSparks··on Why does it take so long for us to form our first memory?
Another item in the long list of obvious stuff so called experts in intelligence purport not to know.

simple answer you wont get from her majesties propoganda channel.

"memory" is a learnt skill. just like everything else, it takes a few years to learn it.

mSparks··on Google reverses its ‘digital death sentence’ for Pixel phone resellers
Google is not a tier 1 provider, there are only 6 of them.

Putting traffic into a tier 1 network costs, taking it pays.

A massive surge from Googles hardware onto the tier 1 networks will be very, very expensive.

Last time it came up was as the BitTorrent protocol started blowing up ISPs that couldn't pay the bills.

mSparks··on Show HN: Code2flow – easy flowcharts with no mouse, no dragging and no hassle
But requires "royality free" distribution. so charging per month and limiting to internal use only for self hosted product isnt in agreement with the licence.
mSparks··on Show HN: Code2flow – easy flowcharts with no mouse, no dragging and no hassle
Not even sure using graphvis in this way is legal. I certainly wont be paying $300 a month for a free download. At&t certainly wont be pleased.
mSparks··on Google reverses its ‘digital death sentence’ for Pixel phone resellers
I didn't say anything about "quitting".

Just a significant number deciding it is time to back up their content.

And at the backbone level it is all charged by the Mbps for example http://www.level3.com/en/legal/ip-traffic-exchange-policy/ http://blog.streamingmedia.com/2014/02/transit-works-costs-i... So a jump in a significant portion of the user base from a few MB per user per day to several GB will be several thousand times more expensive for that day.

mSparks··on Google reverses its ‘digital death sentence’ for Pixel phone resellers
100 million users downloading 15Gigs of email each is not "trivial", even if its $0.00000001 per MB

And gmail has 1 Billion monthly active users, so that is quite likely a conservative guestimate.

I don't think its implausible that shutting down these guys accounts will cost google a 7 or 8 figure sum in (non budgeted) backbone bandwidth charges alone.

mSparks··on Google reverses its ‘digital death sentence’ for Pixel phone resellers
i very much suspect this story is to try and shut the stable door on exactly that bolted horse.

with gmvault now floating at the top of the page i can imagine the gmail adminstrators on the phone to the account managers every few minutes relaying just how many hundreds of terabytes a second in backup bandwidth closing the accounts is now costing them.

mSparks··on Parsing malformed JSON
my first reaction would be to parse until you hit a problem. then use a string distance function and a genetic algorithm to find the problematic characters.

in other words. find multiple possibilities that result in valid a json object and choose the one with the shortest distance.

then, of course log out the changes.

I do something similar with csvs. mssql is notorious for spitting out junk inside csv files.

also, i can guess how it was created.

the code is probably in c, and a rare edge case is overwriting memory before it hits the file.

This is the one thing I wholly side with the conspiracy crew on.

mSparks··on You Don’t Need a Master Plan, You Just Need to Start
Not really survivorship bias? Although if you can be clearer what you mean.

IMHO "Almost all startups fail" - not because they don't have a good plan, a great idea, or "fail to start"

They fail because they don't have the motivation (or capability) to push through the inevitable hard times and come out the other side strong and profitable.

It takes a very special dedication to take an idea from start to profit.

And it seems most "Master Plans" are to cobble together a good idea then sell it for millions to a greater fool.
