ff7c11··on Show HN: Kim – A Python serialization and marshaling framework
why not pickle :) :)
ff7c11··on A deep dive into why Wi-Fi kind of sucks
Is there a way I can just not obey the collision domain and transmit over someone else anyway? Would that allow me to skip the queue or would nobody get any service?

ff7c11··on Microsoft Acquires Xamarin
It had been on the cards for quite some time. Like everyone, I'm hoping for a massive change in pricing structure.
ff7c11··on Why aren’t app permissions reflected in app classifications?
The content rating systems should help parents make choices about what apps are acceptable. They should reflect whether the app can record information about the child.

I like that analogy
ff7c11··on Berlin public transport in real time
Randomise the destinations as well. Will play havoc with the terrorists.
ff7c11··on Berlin public transport in real time
This is cooler than the Berlin one tbh
ff7c11··on Berlin public transport in real time
Ah. So no use in real-time if there is an unplanned delay as the map will show that the train just went past you when in fact it didn't. Shame.
ff7c11··on Berlin public transport in real time
I thought the same. But I can't actually come up with a good reason. Maybe German trains are so punctual that you can infer their position anyway. Can someone in Berlin measure the lag? Next time I'm back there I might test it.

Was glad to see them using OpenStreetMap.

ff7c11··on Biohackers Creating Open-Source Insulin
Misfolded proteins also cause Alzheimer's disease. They are the number one reason why cannibalism is bad. If you eat a human brain with misfolded human proteins (prions) it can cause your proteins to misfold. I think.
ff7c11··on Biohackers Creating Open-Source Insulin
Not going to happen. "Biohacking" is 100% hype. 0% science. On insulin specifically: http://blog.indysci.org/insulin-is-hard-but-not-impossible/

Best comment on page so far:

QUICK, HURRY We need to quickly ban this SMS technology to prevent the next attack.

I quite liked the score sheet and playback plugin
ff7c11··on A URL shortener service in 45 lines of Scala
In print: I like how net magazine uses netm.ag/description-123 for any links so it's easy to type and doesn't take up too much space. This also gives analytics for print articles where you normally can't watch whether anyone followed a link

You don't need to rely on routing through Twitter. Works when Twitter blocked or down. Branding.

Also tracking.

Also you can modify where the link points after distributing it in case you notice a mistake.

I love the use of Google's Latin-English dictionary. Which amazingly also includes the word microwave.

ff7c11··on MiniLock – File encryption software that does more with less
Oooh I like this a lot. Very clever. How many trigrams do you actually choose from?
ff7c11··on MiniLock – File encryption software that does more with less
Yeah use of zxcvbn is a problem. Minilock's key strength checking goes[0]:

  key.length > 32 && zxcvbn(key).entropy > 100
Firstly minilock allows the following: zxcvbn(". . . . . . . . . . . . . . . . ").entropy = 161.421 [1]

Secondly this only really works for English. While they are used to being forced to use English passwords, we can't expect that speakers of other languages would like English passphrases. It also has heuristics making assumptions of how people choose passwords (e.g. l33tifying) which may be less valid for longer phrases than short passwords. zxcvbn uses all English word lists and keyboard layout and automatically gives you a Unicode bonus[2] if you use unexpected characters. If I write a sentence in Chinese, I have a high entropy. Here minilock actually penalises Chinese by adding the key.length > 32 requirement as 32 Chinese characters is equivalent to a much longer English passphrase. I suggest lowering the key length requirement in this case. However, if my passphrase were in Arabic and my attacker knew it was likely to be in the Arabic alphabet, I'm not really entitled to the aforementioned Unicode bonus as the entropy drops to be similar to English (I think).

That said, the design decisions of zxcvbn do make sense for Dropbox and zxcvbn is not the crucial part of the minilock program (the crypto is). Users will always find a way to game the system and find the lowest possible entropy passphrase.

I think so you can use it from any computer anywhere with just the passphrase to derive the key and don't need to carry and secure a file.

They call it

  ...a free, open way to make every house ...
and then they say

  The mapcode algorithms and data tables may not be
  altered in any way
not very open
ff7c11··on Making of Aprilzero
Ok, but the lifestyle of just hoping on a plane somewhere to get into the mind of an explorer requires you to be getting funding from somewhere (though perhaps not dev work)
ff7c11··on JSON Resume – a JSON-based open source standard for resumes
http://microformats.org/wiki/h-resume looks good as you can choose how you want to display the data as well as allowing parsing to JSON if you want
