rikf··on Flow Control in Aeron
I think the main use case is high frequency trading.
rikf··on Apple acquires sleep tracking company Beddit
Surely the reason this isn't a thing is because the watch needs to be charged every night?
rikf··on PM of Singapore Shares His C++ Sudoku Solver Source Code
This is awesome and I don't wanna hate but the question has to be asked why c++?

There are tens more languages that are more modern and "aspirational"

rikf··on Apple Watch – What can you do with it?
Interesting that apple seems to be following the same model as they did with their mobile devices in terms of developer functionality. Their view seems to be to start off really tightly locked down and then gradually open up additional features to developers. It makes sense in that its much easier to open stuff up after its been locked down then to lock down stuff once people have built stuff on it.
rikf··on Ask HN: Why do people have a hatred for Scala?
I dabbled in scala for a while a few years ago and ultimately decided not to invest the time becoming an expert in it for the following reasons. 1) Slow compile times, I really value fast feedback and if it takes me over a second to compile and run a unit test that just doesn't cut it for me. 2) No clear idiomatic style and having many different ways of doing things each of which can imply different behaviour in different contexts.
rikf··on SpaceX Has Pinpointed the Problem That Caused the Falcon9 to Crash Land
Seems like they actually use RP-1 (rocket fuel) as the hydraulic fluid so that it is burned as fuel after it has been used. This means that the hydraulic fluid isnt "dead mass"
rikf··on Amazon is hiring Clojure devs
I wonder what the sable referred to in the job description is referring to? Could it be SableVM.SableVM is a clean room implementation of the JVM but is no longer being maintained.

rikf··on Java Garbage Collection Distilled (2013)
I agree with everything you said. Here is an interesting lwn article from when the azule people originally tried to push their change/enhancements upstream.

http://lwn.net/Articles/392307/

Seems like either the quality wasnt there or the linux people where resistant to change.

Some more info here. http://en.wikipedia.org/wiki/User:AzulPM/Managed_Runtime_Ini...

Its a pitty that this type of GC hasn't found widespread use because it gives us the best of both worlds, in terms of automatics memory management and performance.

edit for spelling mistake

rikf··on Whited00r: iOS Community Custom Firmware
You can actually get an iPhone 4S replacement battery + tools to change the battery for less then $10 dollars. Certainly a-lot cheaper than replacing the whole phone.

Here is one for $9 http://www.ebay.com/itm/1430mAh-Internal-Replacement-3-7V-Li...

rikf··on Apple to Cease Development of Aperture and Transition Users to Photos for OS X
Aqua (GUI) and Terminal (CLI)
rikf··on Protests against Uber are heating up in Europe
As a London native for almost 10 years I cant tell you how many times I have been ripped off by black cab drivers taking longer routes then they could have. I also cant tell you how difficult it can be at certain times to find a taxi to take you home so people inevitably end up using unlicensed "mini cabs" to get home. This all because the licensing regulations are stuck in the stone age. Hopefully Uber will drag London kicking and screaming into the 21st century.

As a side note I also dont think there is anything stopping a London black cab driver from signing up for Uber.

rikf··on The Spectacular Failure Of Better Place
I think there are two many lessons that can be learnt from this story.

1. Stay focussed. 2. Keep your team as small as possible.

rikf··on Tesla Adds Titanium Underbody Shield and Aluminum Deflector Plates to Model S
The biggest take away from that article for me is that they are offering the fix for free to current owners. How many other car companies would do that? Unless they where required to by law which is clearly not the case here.
rikf··on Clojure 1.6 released
If your writing tests after the unit then you not doing TDD right.

TDD is not designed to be a good technique for developing algorithm's but rather for designing OO systems and discovering the collaborations between various objects within a system. This doesn't mean you can forget about solid OO design principals and just somehow land up with a good design just because you use TDD.

rikf··on Apple in Talks with Comcast About Streaming-TV Service
In the UK at least I think its only a matter of time before either google or apple but in a huge bid for the premier league TV rights. It would give them huge penetration for there TV offerings almost over night.
rikf··on NetBeans IDE 8.0
Have you tried IntelliJ? I haven't used netbeans for years but for me IntelliJ is light years ahead of eclipse. I would be interested to hear from anybody who has tried both for a reasonable amount of time.
rikf··on New £1 coin to be introduced to combat counterfeiting
I am amazed that people would go through the effort to counterfeit a £1 coin, you would literally need to counterfeit millions of coins to make the enterprise worthwhile and then how would you launder them all? Obviously the benefit is worth more then the cost but I find it strange none the less
rikf··on This Man's $600K Facebook Disaster Is a Warning For All Small Businesses
It should be possible to determine fake from real accounts using various statistics like number of likes per account average number of time between likes etc etc, with all the brainpower at Facebook I am surprised they haven't significantly mitigated this problem. This is not a problem that can ever be completely solved as its a typical arms race between good and evil but i am surprised at how badly Facebook appears to be doing as others have noted perhaps its because it in there best interest or maybe its just more visible on Facebook then it would be on google addwords or similar.
rikf··on Facebook Buying WhatsApp for $16B in Cash and Stock Plus $3B in RSUs
You get a hell of a-lot of R&D, talent infrastructure and pretty much anything for $16B think Facebook with its engineering talent would find it fairly trivial to replicate the tech. The big consumer internet acquisitions are very rarely about the technologies and more about the installed user base.
rikf··on Ding.io
I like the happy hippo behind the mba on the landing page :)

All in all its a great introduction to the service, really well put together.

rikf··on Show HN: Snapbugz – The easiest way to discuss bugs.
Looks very useful to me.

One things I would do is make the permalink visible as soon in the flow as possible.

rikf··on State of the Octoverse 2013
It seems like only the early employees get cool nickname I thought github has an eglatarian culture?
rikf··on Paper, by MiSoft
If your apps biggest selling point is that its named after a commonly used noun then I think you have problems. Its a similar concept to idea vs execution. We saw the same thing at the start of the internet revolution with domain squatting.
rikf··on A killer app for Bitcoin? – Spam and Phishing Emails Killer
I was going to post the same thing, have always like the idea of hashcash and surprised it hasnt recieved greater usage specifically for things like captchas although in the case it would be a reverse captcha :)

edit

Could potentially be used a a form of ddos mitigation if the browser was required to design a tiny bit of hash cash for each request, although I haven't really thought through all the details.

rikf··on Nvidia Brings Kepler to Mobile Devices
I wonder how you would deal with the extra heat output in a desktop state.
rikf··on Google Reader Apocalypse Extremely Fucking Nigh
I dont think they are killing ready because of the cost to maintain it. I think its more likely a strategic move to push people onto plus.
rikf··on Always Be Coding – How to Land an Engineering Job
The only recruitment process I know of that works is.

Step 1) Send the candidate a small unattended coding test they can do in a couple of hours. If they pass great if they dont offer them feedback.

Step 2) Invite them in for a pair programming test this should take max one hour, they can spend 15-30 minutes with one or two people on the team solving a problem.

You wouldn't believe the amount of people who have amazing looking CV's but when it comes to actually coding they just are not up to scratch.

There is also obviously personality fit and other subtleties but thats the basics.

rikf··on Duplicate your House Keys with your Phone
I a, pretty certain they will pad the envelope so it's not immediately obvious that there is a key in there.
rikf··on What happens when you give 4chan images of the Boston Marathon?
This is happening in London although with ground based rather then air based sensors. http://www.westminster.gov.uk/services/transportandstreets/p...
rikf··on Foursquare raises $41 million Series D round
As another comment already stated they have become a "boring yelp competitor" I think it is exactly this geographical information that they have in this database that is the main value the company has. If anybody wants to compete with Google on maps they will need this info. I think the investors are looking for an acquisition Yahoo/Facebook/Ms.
