Will Apple lose innovation as CEO Steve Jobs resigns? Who is the replacement?

Will Apple lose innovation as CEO Steve Jobs resigns? Who is the replacement?

Many speculated this would happne but it appears Apple’s glory days could come to an end unless the invent something like little Martians who will charge your Ipad for you. Or something like that. Maybe an Apple TV. What is next for Apple?

How Google ranks Adwords with Quality Score? Source is explained by Google itself

How Google ranks Adwords with Quality Score? Source is explained by Google itself

I may start my first campaign with Google Adwords but this was explained by a fantastic Google Adwords consultant. It seems if you spend $3 for a click and your campaign gets a quality score of 1-10, you multiply the 2. For example, you spend $2 a click with a quality score of 7, you get 15. So if you get a competitor willing to beat your total, they will have to spend more money per click but Google does remember the history of your quality score over a few months. So if you initially have a higher quality score historically, you can maintain your positions. Even if you drop your daily budget for your campaign, you can still maintain the history of your quality score. Confused? So was I.

Actually, if you also are willing to spend more on your daily budget, you can improve your quality score as you get more traffic. I am talking about keywords for my niche which does not generate a lot of traffic. If you spend only $10/day, you get a much lower quality score versus if you spend $100/day. As you get more traffic you increase your chances of upping the click through rate as well which your quality score is measured.

Google Policies are very stringent. The consultant said that Google wants only family friendly sites on the Adwords platform. They don’t want arbitrage that affiliate marketers use by redirecting to another page. They also don’t like those quick rich schemes as well. Those days seem done for any internet marketers.  No firearms as well.  So they only want quality product on the Adwords platform.

Language could pave the way for native parallelism in C and C++.

Ok so the marketing consultants feel this is a good place to post the announcement, but I’m curious… Can anyone actually say they are using this in HPC? Do you think other vendors like PathScale/PGI should adopt it?

 

Seriously? When app SW and tools continues to be our greatest challenge,
you don’t believe this move might be of interest to the HPC community?

 

I’m seriously not kidding at all. Pragmatically speaking what problem does it solve that isn’t already solved? Sure I’ve only glanced at it, but 1) how much existing cilk code is used in HPC 2) how well does the programming model fit with GPU or a heterogeneous cluster (honest question) 3) Is there a test-suite that’s being opened as well 4) any empirical evidence showing a performance gain vs openmp or something comparable 5) when has Intel ever open sourced anything that was of any value..

IMHO it solves nothing and we have enough programing model proliferation as it is. Show me where I’m wrong and then we come back to my original question about if other vendors should implement it.

With my open source hat on it’s party time and I don’t want to come across as negative. With my HPC hat on I’m skeptical and we’ll see if helps them lock people in…

—-

I think it is a good option. It does not solve everybody’s problem and will require some works. But it provides much better approches than patch directives that do not address the core issues of heterogeneous computing.

 

I don’t see Cilk solving anything in HPC. It looks like a great tool for thread programming and task parallelism. However, HPC is to a large extent data parallel. Watch the success of GPUs, which are data parallel monsters. Yes, they use threads, but these are generated in a data parallel way, not by the fork/join paradigm that Cilk is based on.

 

I would ask directly to Leiserson and Frigo what is Cilk’s contribution: finding a good solution of thread allocation to cores, no matter what cores or threads, it is a difficult and useful problem. In GPUs Cilks is not the preferred solution because other tools provide better scheduling. In general, I would say to write good parallel code the developer and the compiler have to work together. Cilk is an interesting attempt to do just that. Will see.

—–

I think Cilk model of programming is suitable for irregular applications such as graphs, and sparse matrices. Its scheduler used to perform amazingly well when it used to be called CilkArts Cilk++ (about 2 years ago). I am happy with this move because the Cilk Plus embedded inside Intel’s compilers wasn’t as good (perhaps due to different stack allocation rules). The downsides of Cilk are that you can’t schedule arbitrary dags directly (yes, you can hack the system to do that but then it doesn’t perform well) and there is no NUMA aware stealing. Both of these shortcomings are intentional (if you ask Leiserson or Frigo) because you can’t get parallelism and optimality proofs without them. However, as Cilk becomes a practical tool than solely an academic paper machine, I think it’s time those constraints are relaxed.

—-

I like the simplicity and elegance. It should promote cleaner code with less debugging. I think some versions (shared memory?) of the FFTW package (quite popular in HPC space) was written using Cilk.

Is anybody using social networking data for sentiment analysis in their trading strategies?

Is anybody using social networking data for sentiment analysis in their trading strategies?

Countless people use sentiment analysis with news articles to detect market mood, it seems now many people are trying to integrate publicly available social data (from Twitter for example) into trading strategies; using sentiment as a trade indicator. Is anybody here doing this? Do we think there is any significant advantage here or is it likely to consist of a lot of ‘junk’ posts that just add to market noise and make life harder? Would love to hear your thoughts on this in terms of ways to successfully implement this kind of analysis into a strategy.

Are you familiar with the recent academic paper discussing this very subject, the author has subsequently started a hedge fund trading the research paper idea. I have forgotten the details of who the author is but a google search should provide the answer.

I think this is an exciting new era of research for sentiment traders like myself. There will be lots of new ideas and tools coming forward on this topic. I have for example an app on my iPhone called WS Scanner which supposedly does something similar. I wouldn’t trust the app, but I think it speaks to the future of the information of social media
