dalek2point3··on The cost of Linux's page fault handling
thanks! this is a great explanation.
dalek2point3··on We just interviewed at Y Combinator – here’s the full transcript
tl;dr version:

snip.ly a startup that is building a link shortner with a call to action built-in gets rejected by YC for not being the "next Google" (example shortlink: http://snip.ly/as6)

dalek2point3··on The cost of Linux's page fault handling
I'm a complete noob when it comes to kernel development -- but this seems super interesting. Anyone care to explain what's going on?
dalek2point3··on Porting 600k Map Views to OpenStreetMap/MapBox
yes and no. In terms of street coverage, the general idea is that OSM is pretty good (in large part because both Google and OSM source map data from the US census) and both have active communities that improve that data.

Google is much better when it comes to both places and addresses, but OpenStreetMap is improving rapidly and you can get great coverage in most big cities. Also in theory you could source the POI data from some other place and overlay that on top of OSM street data.

Google used to be much better in terms of ease of use, but with players like MapBox that has changed dramatically. Its so pleasant these days to use OSM to make a mapping product -- try out cartodb.com or mapbox.com just for kicks.

And the big plus of OSM of course is that you can pick and choose what data you want to render, what you want to do with it (my fav new example is this scooter routing engine that takes into account the hills in SF while routing --> https://www.mapbox.com/blog/launching-smart-directions/)

As for "hard data" -- here are a couple of studies that compare OSM with private map providers

dalek2point3··on Wikipedia Redesign Concept
isnt there a way to have your cake and eat it too? WIkipedia is CC-BY-SA so it should be possible to maintain a mirror of Wikipedia with a more souped up interface? I guess the costs of maintaining would be pretty high but Wikipedia allows commercial use so you should be able to slap some advertising on it. in fact im suprised people havent tried this already. perhaps they have?
dalek2point3··on The TeX tuneup of 2014 [pdf]
feature request: can someone please work on making TeX error messages more readable? i dont know how the project is structured and dont know where to begin. i compile TeX documents daily but I still cringe at the compile output. Its mostly gibberish and does not warrant something that most of the scientific world uses for word processing ...

What would a version of TeX reimagined by Jony Ive look like?

dalek2point3··on Japan's Plan for Centimeter-Resolution GPS
Very interesting. Actually, something similar happened in the US back in 2000, when Clinton turned off something called "Selective Availability" in the US. This program deliberately degraded civilian GPS signals. After SA was turned off, we went from a GPS system that was accurate to a football field-type area to one that is accurate to a tennis-court ish area.

dalek2point3··on Which Cities Sleep in, and Which Get to Work Early
I wanted to point out out that the source of the data is pretty limited. There must be a better way to do this -- eg. looking at sybway traffic, internet searches? I dunno, something that would pick up signals from more people and do so on a global scale rather than the national scale. Surely we think the global variation is more interesting than the national one.
dalek2point3··on OnePlus One – $299 CyanogenMod 'killer' smartphone
the video on the homepage is pretty bad. I dont want to look at some guy making sketches of the design, i want to see the phone. Also, isnt software a big sell for this Cynagen? I've never installed the Mod before -- can the video show me how the insides of the phone are supposed to look like? pretty please?
dalek2point3··on Space Monkey dumps Python for Go
Can someone tell me how much control GOOG has over the development of Go? I'm interested, but worry that is this another GOOG "open source" project that they have a huge say in.
dalek2point3··on Supreme Court to hear arguments on Aereo this week
Katie Couric did this great interview of Chet Kanojia on Yahoo that is definitely worth checking out. http://news.yahoo.com/video/aereo-broadcast-tv-worst-nightma...

In it, the Aereo CEO admits to being "anxious" because the $100 million on the company is essentially down the drain depending on what the Supreme Court decides. He says, this is mainly due to the 110-odd people who work at the firm. Fair-nuff -- seems like a reasonable sort-a guy.

dalek2point3··on When to Hold Out For a Lower Airfare
tl;dr version

You will probably not save any money following Kayak’s price prediction algorithm and instead buying tickets two weeks ahead of your scheduled departure is a reasonable strategy. You should use prediction algorithms anyway, because they wont lose you money either and help you gain "piece of mind".

dalek2point3··on NYC Subway Data REST API
+! GTFS is super awesome and most apps I know rely on it. Its consistent format that is adopted by transit systems across the globe. couldnt get more developer friendly than that. If you developed with this RESTful API, it would be hard to adapt your app to use the feed for a different city.
dalek2point3··on British Pathé Puts Over 85,000 Historical Films on YouTube
Actually, they dont really need to upload to archive.org to make it reusable. Youtube has the option to place this material under a liberal CC license. The least they can do is change the license so that this material is then free for reuse.
dalek2point3··on British Pathé Puts Over 85,000 Historical Films on YouTube
Not true. My research suggests that once it has been archives, provided that copyright is not an issue, the material will be reused in useful ways.

dalek2point3··on Creating maps using R, Deedle and F# type providers
and remember if you need a basemap that is more than simply all the countries in the world, you can use openstreetmap.org! Downloads of raw data in various forms can be found at : download.geofabrik.de/
dalek2point3··on Network of 75 Million Neurons of the Mouse Brain Mapped for the First Time
i'm wondering if the massive amounts of Petabytes can be compressed in some efficient way. probably.
dalek2point3··on Network of 75 Million Neurons of the Mouse Brain Mapped for the First Time
two questions for someone more familiar with this area:

1. what are the immediate applications of having such a dataset? either for the mouse or the brain?

2. once we have the map, will we also have the technology to identify precisely what neurons are lighting up and how information is travelling during certain actions / responses? in short how far are we from a green / yellow / red Google Maps style traffic map for the brain?

dalek2point3··on Twitter Acquires Gnip
does this mean that they will no longer sell non-twitter data like Foursquare?
dalek2point3··on Glow-in-the-dark roads make debut in Netherlands
how can an article about glow in the dark roads not have real pictures of glow in the dark roads? (sadface)
dalek2point3··on Amazon Preparing to Release Smartphone
I'm wondering how come no one is talking about the elephant in the room. Google Services! No one really cares about Android's "open"-ness anyone, because without Goog services a smartphone is virtually nothing -- you need maps, youtube and gmail at the very least. AMZN has a plan for that?
dalek2point3··on “In a typical year the OpenSSL project receives about US $2000 in donations”
this might not necessarily be a good thing. see: http://en.wikipedia.org/wiki/Motivation_crowding_theory
dalek2point3··on Booking Video: Aaron Swartz Jokes, Jousts With Cops After MIT Bust
chilling, absolutely chilling -- that this happens for writing code. hell, scraping a website. i agree that what Aaron did was not a 100% legal, but to equate it with a criminal offence? Bah! Support Aaron's Law! https://www.eff.org/deeplinks/2013/06/aarons-law-introduced-...
dalek2point3··on Show HN: TruckPlease – Moving sucks, so we decided to make it easier
tell me about it! I rented a Uhaul last year during this time, and it was a complete nightmare. Im wondering how much extra money I have to pay on this site to make it less painful and whether it would be worth it.
dalek2point3··on The problem with profitless startups
tl;dr the author argues that the ultra-cheap venture backed services are a problem because while they're using money from VC firms and being patient, they're driving out local businesses, and they'll ultimately fail, leaving a hole in the local service ecosystem.
dalek2point3··on LastPass Now Checks If Your Sites Are Affected by Heartbleed
BankOfAmerica, perhaps my most important site from a security point of view does not seem to care: https://lastpass.com/heartbleed/?h=bankofamerica.com
dalek2point3··on Massachusetts Governor Announces Plan to Abolish Noncompetes
My professor at MIT has done some of the most path breaking research on the impact of non-competes on innovation, and what he finds is mostly negative. http://mitsloanexperts.mit.edu/matthew-marx-non-compete-agre...

This is the best example for the impact of policy-driven legislation.

dalek2point3··on Ask HN: What do you do when you're not working/programming?
me too! where do you edit?
dalek2point3··on Ask HN: Review my startup: JobKaster Google Maps for Jobs
have you looked at mapbox.com? they make beautiful openstreetmap based maps -- which you can really use in powerful ways because you have access to the raw data. It will definitely pay off in the long run if you're looking to build a map-based app.

PS: not affiliated with mapbox in any way.

dalek2point3··on Software Gets the World to Stop (Over) Eating
