vizard··on Peter Thiel: Best Predictor of Startup Success Is Low CEO Pay
What about performance related pay? For example, pay directly tied to profits?
vizard··on Fire burns building at Apple HQ in California
Man we need an "apple" filter. Most of the apple related news on HN is getting ridiculous while you can still get important apple news on any other news site.
vizard··on What were you doing during the first dot boom?
I was in the tenth grade and breaking all my personal weight records by gaining 5kg/month.
vizard··on Ask YC: MacBook alternative?
Dell XPS M1330 preloaded with Ubuntu. No hassles of installation at least. In any case whatever notebook you choose, do a bit of research to find out that the wireless card works properly under linux. I have had decent experience with Intel's wifi cards since drivers are open source and hence included in most distros. Wifi is the number one annoyance on most notebooks.

edit : I wud advice to look for "Centrino" branded stuff. That usually works out of the box. But YMMV.

vizard··on Erlang as middleware
Thanks for infusing realism into the Erlang hype. As you point out "There is no free lunch". People also frequently tend to forget Amdahl's law when discussing Erlang and somehow assume that "Erlang = Linear Scaling" regardless of algorithm and problem.
vizard··on Field Guide to Genetic Programming (Free Book)
Isnt GP patented? That will probably kill off any commercial applications.
vizard··on The Eyes Have It: Last week's Apple mystery is all about video chips
Why are we seeing so many mac rumors including completely unsubstantiated and unfounded ones? Please dont convert this site to macrumor or appleinsider.
vizard··on Scaling Python for High-Load Web Sites
Umm most of the slides appear empty to me with one or two lines written in each slide. Maybe somethings broken with my browser (ff3 on linux).
vizard··on Ex-Google engineers debut 'Cuil' way to search
hmm slightly weird. I searched for a term and didnt get any results. I searched for the same term 10 minutes later and i got results? Anyway, some stuff is not returning any results : "nvidia gtx 280" didnt return any result :(
vizard··on Linux development on the PlayStation 3: More than a toy
I feel IBM hasnt really taken Cell to its full potential and it will probably lose the performance crown to x86 in 2-3 years unless IBM gives the performance a badly needed performance boost. GPUs can also beat cell in some tasks.
vizard··on Hector Ruiz out at AMD, Dirk Meyer new CEO
I wonder who will buy the handheld graphics divison. Any ideas? Current competitors in the handheld divison are imagination technologies and nvidia and neither will probably buy the Imageon divison. Perhaps qualcomm might buy them given that qualcomm is using Imageon in its own SoC?

Sorry for replying a bit late. For FFTs, flops are measured in a standardized way. If you are doing an FFT of length N, the number of flops is counted as 5 N log N no matter how the actual FFT is computed. So, in the case of FFT, really you just specify a length N and measure the time.

For CPUs, the numbers using FFTW, one of the fastest FFT libraries that does take advantage of SIMD, the numbers usually do not exceed 5-6 gflops particularly for larger lengths.

OTOH, the above 55 gflops figure is also somewhat misleading since it does not include transfer time of data b/w RAM and GPU. Actual throughput is somewhere around 20gflops. On one particular project using FFT, I got around 15 gflops using GPU including transfer time while testing several FFT libraries, I never got above 3 gflops on a 2.4ghz quad-core using all four cores. The lenghts were big enough not to fit into cache thus reducing CPU performance considerably.

I wonder if a GPU might be more suitable for his task. Even the 8800GTX is known to do single precision FFTs at more than 55 Gflops which is an order of magnitude more than even contemporary CPUs let alone P4.

Does anyone know if it will be restricted to US?

Does anybody here have experience with both the iPhone SDK and Android SDK? If so, any thoughts?
vizard··on AMD Is Fighting For Its Life
Well lets consider this for a moment.

1. Apple's main bread-earner right now is the Macbook, MBP and iMac. All of them are premium models and significantly, all of them use mobile processors. Only the Mac Pro uses desktop processors. AMD's mobile line cannot compete with Core 2 Duo currently and is only found in cheaper laptops. I cannot see what apple gain by acquiring AMD. And what exactly will they do after acquiring AMD? Not buy Intel processors anymore and instead compete with Penryn and (future) Nehalem? And once again lose out to generic Windows boxes in the performance game?

2. Apple has no chip expertise in the desktop/laptop area. They have a small inhouse chip divison but its dedicated to mobiles and handhelds. Their recent acquisition was also in this space and was fairly small (less than $50mn if i remember).

3. Apple does not have the resources to compete with Intel. OTOH they have a very good working relationship with Intel and I dont see why they would want to disrupt that and instead focus on non-core areas.

vizard··on AMD Is Fighting For Its Life
I think ATI will be bought off by someone .. maybe even Intel given that Intel is now developing its own GPUs. On the x86 front, the only possible acquirer for AMD CPU divison seems to be IBM.

Sun also bought a x86 startup a few months back but Sun has its own problems. Samsung was considered as another contender but Samsung wont actually get the x86 license (the license can only be transferred to US based companies I believe).

Or maybe AMD will survive. They need to find a new management and probably need to deeply collaborate with IBM on fabs and tech.

Despite Nvidia's sabre rattling, it cannot compete with Intel on the CPU front though Intel certainly has the resources to give Nvidia a fight.

vizard··on The iPhone 1.0 critics -- where are they now?
My bad .. should have looked up wikipedia first.
vizard··on The iPhone 1.0 critics -- where are they now?
Aah thanks. The claims and graphs by various vendors can be very difficult to make sense of sometimes.
vizard··on The iPhone 1.0 critics -- where are they now?
OT : Does anyone know specific marketshare numbers about the iPhone vs WinMobile and Symbian? I am having a hard time tracking them down. Jobs claimed iPhone outselling all Windows Mobile combined.
vizard··on Andreessen: "If you own newspapers, sell. If you own TV stations, sell..."
The examples you quote are all technologies. What Marc is also predicting is a change in the technology of content distribution.

But what is not gonna go away are content producers. I still prefer watching movies made by Hollywood than home-made videos of cats. Where and how I watch movies may change but the fact that I will still watch professional made movies is not very likely to change.

Similarly newspapers may go away as a content distribution mechanism. But professional reporters and news agencies may not necessarily go away even with bloggers and social news sites and so on.

vizard··on Ask HN : Music for boosting brain function, fake or real?
oh thanks for notifying. fixed to http://getimusic.com (forgot the "i" in the middle before).
vizard··on Ask HN : Best Computer graphics book?
Thanks for the book recommendation :) One of my friends also asked me to look at "Real time rendering" second edition by Moller/Haines. Any thoughts?
vizard··on Small group @ TI readying a low-cost development board, open hardware design
Entry of Intel in the mobile segment is forcing traditional ARM-based SoC makers to open up their software tools etc. Even though Intel doesnt have anything that competes with OMAP series lets say, Intel does have a thoroughly documented instruction set and one which is very well supported by compilers etc. Compared to it, compilers for TI DSP's for example still cost a fortune usually.
vizard··on Happy Independence Day!
except for people outside US.
vizard··on Results of our Ruby development survey
Does anybody here actually use gedit? And why?

edit : genuinely curious. not trying to put down gedit.
