rikf··on Collaborative chat done right
Chat is not done right until you include search functionality. There is an incredible wealth of information that is exchanged through mediums like this that just gets lost if you don't have a good search function. So at the moment this is collaborative chat done wrong :) I hope you accept this as constructive criticism because other then that the product looks pretty well designed.
rikf··on Bitcoin hits $200
It does have certain mathematical properties that make it rare. or at least harder and harder to produce as times goes on that leads to scarcity. And as we all know price = demand / supply
rikf··on VMware to cut 900 jobs
Basically a single physical server running 10's to 100's of virtualized servers. With all the management challenges that entails.
rikf··on Tesla Was Cash Flow Positive Last Week, CEO Musk Says
I think you would be surprised I think Tesla's strategy has three stages.

1) Niche high cost vehicle sold in low volumes(Roadster)

2) Medium cost luxury vehicle sold in medium volumes(Model S)

3) Low cost high volume vehicle sold in high volumes. (Model ???)

Obviously this is a gross over simplification but I imagine that part of the engineering that is going on at TESLA is figuring out how to build 3 cheaper and at a higher quality then anybody else.

rikf··on Touch Laptops
I dont think its really the cognitive effort that I find annoying but rather the time it actually takes to move my hands from the keyboard to the mouse.

I am firmly in the know thy shortcuts camp and find anything that forces me to move hands away from the keyboard has a negative effect in terms of my productivity. With a mouse and keyboard at least your hands are moving in the same plane.

rikf··on Touch Laptops
I find it annoying when I have to move my hands from the keyboard to the mouse. I imagine it would be infinitely more irritating and far less comfortable moving my hands from the keyboard to touch a vertical screen in front of me.
rikf··on The Architecture of Datomic
Take a look at event sourcing. This is a good introduction. http://martinfowler.com/eaaDev/EventSourcing.html

rikf··on The Tesla Approach to Distributing and Servicing Cars
Dont forget that even traditional gas stations make most of their profit from convenience store/restaurants.
rikf··on More trouble for Color: shareholders and board vote to wind down company
You can develop a-lot of features and hire some (a-lot of) pretty fucking good people for $200m
rikf··on SpaceX aims big with massive new rocket
I thought maybe incorrectly that a carbon nanotube based material would provide the required strength? But we currently do not have the technology to build it?
rikf··on Master Keys
Like a smart terrorist/activist/pranker couldnt learn how to pick locks.
rikf··on Show HN: Meet your cardboard buddy.
This is freaking awesome well done guys. Would love to get these for our team and stick them on our kanban board instead of 2d south park characters!

EDIT: You should also make some animal shapes for pets!

rikf··on 3 Tips for Effective Stand-Up Meetings
Hey Guys, Completley off topic but I really like your product. One thing I think you can improve on your home page is you have a-lot of images but none of them are clickable to maximize/get more details. Think you could make your homepage more interactive check out the simple.com homepage for an idea of what I mean. Hope you find this feedback helpful. :)
rikf··on How we spent Friday night coming back online before Instagram and others
The correct way to do it is as follows.

1) Set up a test environment using puppet or whatever that boots up an image instance and deploys your whole stack to your cloud provider. 2) Deploy your release candidate to this environment. 3) Run some smoke tests, acceptance tests and maybe even a few performance tests against this environment. 4) If all the tests pass store your image somewhere (S3, GitHub) also make sure to tag the image with your release candidate version. 5) You can now deploy this change-set to your production environment.

When things go wrong you will have fully configured servers available almost immediately.

Now granted this is potentially a very long running process but you could simply set this up as a nightly build.

rikf··on WakeMate (YC S09) runs out of cash, co-founder allegedly spams users
Baffling with all the publicity they have surely this character would have been better off with an open and honest kickstarter? Stating they realise they made mistakes in the past how they are going to correct them and what is different or better about the new product. I would have probably contributed because I think its a really interesting product.
rikf··on New Linux Laptops from ZaReason
Think is exactly why macbooks are so popular. I think if a laptop manufacturer spent some (a-lot?) of effort on hardware design to compete with Apple then there would be huge demand from developers. As a developer now I have a laptop choice of

a) Horrible design with linux installed.

b) Beautiful design with a BSD like os installed.

It really is a no brainer. Even Linus uses a MBA I wonder when hardware manufacturers will start to realise that people actually care about owning beautiful things.

rikf··on Head of Time Warner Cable Unfamiliar With Apple's AirPlay
There are loads of internet enabled TV's on the market at the moment that in the UK at least will give you access to youtube, lovefilm (similar to netflix), BBC iPlayer and the streaming services that most channels provide. Similarly the PS3 and XBOX can do similar things. The UI's probably need some work but IP-TV is becoming a reality.
rikf··on Why You Shouldn't Code Alone
A Less experienced programmer does not necessarily mean a bad programmer. Its a myth that the best programming team consists solely of rockstar ninjas. I have worked on teams that consisted entirely of very very good programers and it resulted in a-lot of friction because everybody had there own philosophies and approaches to solving problems. This becomes more true the larger the team gets. I think the best team is a mix of skill and experience mixed with youthful exuberance.
rikf··on Samsung Galaxy S3 smartphone unveiled
> Some people love the iPhone and that is fine- to each his own. I just refuse to believe that the love affair is based on anything other than marketing.

I would argue that the iPhone and indeed most Apple products embody a "Quality without a name" as originally described by Christopher Alexander in a "A timeless way of building" http://www.munnecke.com/islands/qwan.htm . Very few other companies are able to achieve this. I believe that it is for this reason that people develop a greater emotional attachment to Apple products then the products of companies like Samsung. For example Apple products generally feel great to hold and touch while the same cant be said of Samsung's products.

rikf··on Getting the closest string match
This article talks about using levenstein distance to compare the similarity of two words/sentences another great algorithm for fuzzy string matching is http://en.wikipedia.org/wiki/Metaphone it basically compacts a word into its phonetic components and allows you to implement a google type did you mean.

rikf··on Apple’s great GPL purge
Its important to note that one of the main things that differentiates between platforms is the quality and quantity of the available content. If you want to build a platform the first things to do is build great development tools for that platform at making it a platform that is attractive to developers and power users. This strategy has been critical in resurgence of Apple and I doubt that they would want to become a less attractive development platform.

rikf··on Review my startup - Lean Domain Search: The fastest way to find a domain name
I agree the black on bright green text is intense and not very readable. I like the idea but I think you need to tweak the design a little. The layout is pretty good just need to play around with the colors a little bit.
