lightoverhead··on M4 MacBook Pro
The machine is great! How is its performance for AI model training? A lot of library and tools are not built for M series chip
lightoverhead··on Microsoft acquires Revolution Analytics
That's my concern as R studio is open source; VS is not! But anyway, I should applaud for this move of MS. It's a very smart move strategically. R usage is climbing the chart...
lightoverhead··on Microsoft acquires Revolution Analytics
R studio is already a very mature IDE platform for R programming. What's more can you offer than R studio?
lightoverhead··on Ask HN: How to find a reliable lawyer/agent to initialize a startup?
Thank you for your quick responses. However, that's the problem for me that I am lack of connections with CEO/COOs. But I am pretty interested in what you mentioned that there are several great law firms which provide incorporations service for free. Could you list some of them for our reference. I think more people may benefit from such a information. Thank you.
lightoverhead··on How Python became the language of choice for data science
why I get a "-1" on this? Have anyone compared processing text between Perl and Python? I really cannot agree that python is superior to Perl at this task according to my daily work. Some language is popular doesn't mean it's good at everything.

Perl is better at that than Python.
lightoverhead··on How Python became the language of choice for data science
PDL is the Perl packages for numerical science. Unless you did a lot of mathematics computation, PDL is rarely used in my daily routine.
lightoverhead··on How Python became the language of choice for data science
I consider myself a data scientist in bioinformatics field. I have to deal with several hundred GB scale data everyday. IMO, the best tool kit so far is the combination of Perl and R. Because these tools have the richest packages/modules, you can do almost everything with them. As for python, I don't think it can deal with the data I have as efficient as Perl.
lightoverhead··on How to sell: tips from a marketing guy who can actually sell something
I like this post very much. This strategy can be applied anywhere for your success. The core value or target here is "people". You get people's heart, you get everything!
lightoverhead··on Try to digest the Groupon story
Completely agree with OP on this comment! I really doubt Groupon's business model, hardly believe that coupon style business could be a main stream of profit.

Would like to short this IPO when it comes to the stock market.

lightoverhead··on An Introduction to Data Mining
another thought is: if it's possible (I do notice the copyright for this), could we put it on wiki, so everyone can update it after approved by Dr. Saed Sayad to generate a comprehensive one.
lightoverhead··on An Introduction to Data Mining
That's a great overview of data mining. I am wondering if you can somehow insert multivariate analysis into this flow chart. Multivariate analysis may be a good substitute for clustering methods. Thank you for providing such a clear picture.
lightoverhead··on MacBook Air is enough for a work machine
that's the software not the machine. Can pc run photoshop?
lightoverhead··on MacBook Air is enough for a work machine
I'm really not a fun for Mac stuff. It's just a fashion thing, not for work. For the money you spent on Mac, you can definitely buy a cheap powerful machine with free reliable Linux system.

No matter to say its monopoly of market, even an adapter to projector need its own. I have seen so many times someone using a Mac but forgot bringing that stupid adapter for projector, she/he had to change to PC to do the presentation.

Still don't understand why people like such pricey not comparably useful machine.

lightoverhead··on RStudio,a new IDE for R
Cool stuff. But it seems lacking manual to run it. I would like to see manuals about how to build it, run it at command line and etc. Better docs can really add a lot attractions. Anyway, thank you for providing such as beautiful tool. It has been years that R under linux has no such a good IDE.
lightoverhead··on Any idea for starting up a start-up without core computer skills
These are very nice resource for me. Thank you for your info. And Thank you for all the advice given by the above people.
lightoverhead··on Bayesian stats book banned in China
points taken. I updated my original post. sorry for that condescending tone.
lightoverhead··on Bayesian stats book banned in China
Thank you garply. "an education sufficiently advanced to train people to do those things would certainly include Bayesian statistics somewhere in the curriculum" is exactly what I want to convey.
lightoverhead··on Bayesian stats book banned in China
I agree, it's not immediate application. But Bayesian is one of the most important or fundamental knowledge to develop these cutting-edge technologies.
lightoverhead··on Bayesian stats book banned in China
what do you think?
lightoverhead··on Bayesian stats book banned in China
Hi Guys,

I am from China, and of course the Bayesian is taught in China. Only in the culture revolution time, this crazy thing may happen; but it's long time ago when Mao was alive. Now China is a modern society; of course, the Bayesian theory is taught in schools; otherwise how could they send the spaceship to the outer space and have the fastest super computer in the world so far. you are smart hackers, not a bunch of kids controlled by traditional biases. As to censorship, that's right, china has notorious censorship. I guess the author's book must have some contents/examples regarding political issues; not Bayesian itself was the reason for the book being censored. These days, when people talked about censorship, I always think of wiki-leaks ......
