Adsense, adwords or both?

Anyone else used Mahout? What are your experiences with it?

sadiq··on Finding similar items using minhashing
Thanks.

I'm planning to discuss a couple of different techniques (using shingling to actually create the set elements from items is the next one) and then demonstrate them on a large dataset.

I'll start including some Python in the follow up ones.

sadiq··on Finding similar items using minhashing
Heh, you're right, it does look pretty similar. I wasn't aware of that article until someone posted it on Disqus comments just now.

The article came out of my reading the data mining slides from the Ullman - Stanford course, maybe there's common terminology? I know I tried to keep it consistent with the wikipedia Jaccard Index.

sadiq··on Microsoft Shipped 2 Million Units of Windows Phone 7 Software Last Quarter
It seems that this is licenses sold rather than activations.

I'd be interested in knowing their total activations for the quarter though it's certainly lower.

Doesn't compare well with the 300,000 activations/day Google claim to be doing.

The Lazear Jack Of All Trades paper cited is available at http://faculty-gsb.stanford.edu/lazear/Personal/PDFs/Balance... for those following up references
sadiq··on Groupon Insiders Take $345 Million Off The Table In Latest Funding Round
"Somebody also pocketed a $7.5 million “finder’s fee” for helping to put the deal together."

That's interesting and a lot of money. Is it common?

sadiq··on SimpleCDN has been effectively kicked off the Internet by its ISPs w/o warning
The WebhostingTalk thread makes interesting reading: http://www.webhostingtalk.com/showthread.php?t=1005111
sadiq··on Android Market Client Update
"Since most users who request a refund do so within minutes of purchase, we will reduce the refund window on Market to 15 minutes"

I'm concerned that's gone too far the other way. Twenty four hours was too long for a utility/short game but at fifteen minutes, you're cutting it fine if you have installation problems or need to properly evaluate the app.

sadiq··on Evernote makes $800,000 per Month
Crunchbase seems to think they've raised $45.5m so far which strikes me as an awful lot.

I wonder what their growth is like.

sadiq··on Toshiba Introduces MacBook Air 'Blade-Type' SSDs to Mass Market
Anyone know how the Toshiba controllers on these and the MBAs perform, relative to the Intel and recent Sandforce controllers?
sadiq··on HasWifi Shows You Which Flights Have Wifi
It actually varies with the train operator, where you're heading and what class you travel.

That said, you can pick up mobile broadband packages for around $10/month here with 1GB usage which should have coverage for most journeys in to London.

sadiq··on Ask HN: What do you want to tell Microsoft?
Very much the first point here.

Microsoft needs to stop trying to lock me in to their stack at every point and turn. Currently, if I want to use some Microsoft technology i'm forced in to the rest of the ecosystem and that's a hurdle that i'll likely never jump unless there is simply no other option.

In some respects, Microsoft is already at a disadvantage over Free and Open Source technology when starting new projects without legacy issues, just from the simplification of licensing and the supplier diversification. To add extra barriers, such as having to take on larger and larger parts of the Microsoft ecosystem to get the best out of one component just makes things worse.

Positive first step would be once and for all unequivocally clear up any IP issues surrounding both Mono and their library reimplementations to silence any critics. Second would be bringing Mono in to the .NET ecosystem as a first class citizen. I like C# and .NET but i'm highly unlikely to use it unless I have some real choices for deploying it. From what i've seen from Mono, it's an impressive project but not yet on par with Hotspot and the CLR.

On a site note, there have been some positive steps. The move to Apache 2.0 licensing on several recent contributions is a positive step and helps prevent more license proliferation.

Essentially, I want Microsoft to compete for my business with technology that I can deploy without the worry that i'm perennially locked in to one ecosystem and one vendor.

sadiq··on Ask HN: Who's hiring? (September 2010)
My friends at Mendeley in London are looking for a good sysadmin.

sadiq··on Backblaze online backup almost acquired
It's a shame Backblaze don't have a Linux version, it looks like a pretty neat offering.

sadiq··on The true face of flash games
The true face of flash games requires a windows-only exe to download and install first?

I think these guys might have missed the main selling point of flash, it's insane penetration which means pretty much any desktop user can play straight away. If i'm forcing my users to run some random program to play my games properly then I might as well just ship my own executable and get native performance.

sadiq··on Google Web spam - Gabriel Weinberg's Blog
On an tangential note, it's a shame that Google don't offer a service like BOSS (though BOSS could be enhanced by offering revenue sharing, as an alternative to charging per query).

It seems the Google search APIs have actually gone backwards over the last few years.

sadiq··on Reddit costs $33k/month to operate?
Rackspace's dedicated hosting is not a great comparison, they're definitely at the high end of pricing.

That said, don't forget that both the Rackspace and The Planet boxes come with 2 terabytes of transfer which would be $300 from Amazon. When you factor that in, suddenly Rackspace becomes competitive and The Planet vastly cheaper.

Softlayer will sell you a quadcore box with 8GB of ram and 4 terabytes of transfer a month for $200.

sadiq··on Reddit launches a new search engine
Anyone else been having wierd issues with reddit lately?

For long periods of time I get "the service you request is temporarily unavailable. please try again later." on my home internet connection. From other boxes in the UK, it's fine and from friends on the same ISP, it's also fine. It's quite bizarre.

sadiq··on New Amazon EC2 Instance Type - The Cluster Compute Instance
Does this mean they are running Windows under paravirtualisation?
sadiq··on NDrive GPS App Disappears from Apple App Store
If that turns out to be the case, it's interesting to contrast the two different approaches in transparency that Apple and Google took in using their kill switches.
sadiq··on Android vs. iPhone: How Google is winning hearts of developers
An interesting datapoint is this guy:

http://www.reddit.com/r/IAmA/comments/caq8f/iama_developer_w...

Who made the same app for the iPhone and for Android. His ratio was 3:1, which is roughly the ratio of handsets in the US iirc.

sadiq··on PathScale hackers reverse-engineer Nvidia GPUs to write a better compiler
I wonder if they're doing AMD GPUs too?

That should be easier, given the specs for those are freely available.

sadiq··on Twilio Launches Roll-Your-Own Google Voice
Are there any plans for supporting UK customers?

I'd be on this in a flash.

sadiq··on Accounts get in the way of startups working together
Not to mention that you're potentially putting a very crucial part of your company infrastructure in to the hands of another company whose interests are probably not aligned with yours.

What happens to your startup if (though unlikely) in six months time Twitter decides to start charging for authentication or different levels of service?

Something to consider.

sadiq··on Gabriel Weinberg of Duck Duck Go interviewed on Mixergy
I'd love to hear more about the bit earlier on about when and how to decide whether a particular idea is worth continuing putting time in to.
sadiq··on Free app developed in 3 hours hits #1 and makes $20000. What we learned so far.
Well, Apple's iAd is supposedly a $10 CPM and $2 per click.. and they've apparently got $60m of suckers lined up already..

(Actually, i'm interested to see what kind of businesses have conversion rates that can sustain that kind of cost)

sadiq··on ARM, IBM, Samsung and T.I. Form New Company to rollout Linux-Based Devices
TI sell the OMAP. That should be reason enough.
