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


Poor. My M3 Max/128GB is about 20x slower than 4090. For inference it's much better, still much slower than 4090 but it enables working with much larger LLMs albeit at ~10t/s (in comparison, Threadripper 2990WX/256GB does like 0.25t/s). M4 Max is likely going to be ~25% faster than M3 Max based on CPU perf and memory bandwidth.


R studio is already a very mature IDE platform for R programming. What's more can you offer than R studio?


They can fold it into VS so that RStudio can be abandoned, and the premier development platform for R can be locked behind the MS paywall.


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...


R-Studio is a wonderful IDE - kudos to their team. also, if we do this, it'll be free+oss like PTVS. VS itself isnt oss, but at least the pro/community edition is free now.


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.


You don't need connections to reach out to startup CEOs. They are visible and you can easily find or guess their email addresses.


Perl is better at that than Python.


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.


Because in a discussion of "a or b?", a comment on the usefulness of c is irrelevant. If you were attempting to propose that perl is a better data science language for reasons including its text processing, then you needed to say that. If you weren't attempting to do that, then nobody cares about perl in this context.


not (a > b) does not imply (b > a), particularly if there is no clearly defined ordering over a and b


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.


PDL or Perl?


PDL is the Perl packages for numerical science. Unless you did a lot of mathematics computation, PDL is rarely used in my daily routine.


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!


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.


I agree. It's just fundamentals. There's no such thing as a free lunch. No company can offer 50% coupons again and again, and be profitable, so the number of repeat merchants will go down, and Groupon will have to continue spending more to get more dumb merchants.

The customers are all looking for deals, they're not loyal. Plus more and more will get sick of the deals being targeted towards them.

In the end, Groupon is like a Ponzi scheme in that it will need to trick more new merchants to join in as old merchants drop out, and it will need to continue paying a premium to attract more consumers as the existing ones drop out. Compare that to companies like Amazon, and Google where ppl will never get tired of shopping online, or searching online.


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.


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.


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.


Macs "just work" for things where Linux doesn't. Photoshop doesn't run natively on Linux, that's alone is enough for many to choose OS X over Linux.

For many people the price difference (if it's there) doesn't matter.


that's the software not the machine. Can pc run photoshop?


Mac OS X is the only unix based OS that runs Photoshop natively. Macs are the only way to run Mac OS X except if you make a "hackintosh".

Linux is not as user friendly and integrated with the hardware as Macs. There are certain apps that are only available for Mac. Those are some of the reasons.


In this case, the Mac might actually be the better buy if you're just talking hardware. From one review of the most comparable PC, the Samsung Series 9:

"The 13-inch MacBook Air delivers longer battery life, better graphics, and a higher-res display for $350 less, and you can get a 256GB SSD inside for $50 less than the Series 9."

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.
