Why do the UI elements shake on hover?

BinRoo5• 12 years ago

My naive UI decisions. I'm no designer, haha :)

For what it's worth I thought they were cool ;)

Rickasaurus• 12 years ago

This is awesome. Thank you!

m0nastic2• 12 years ago

I'm excited to read this, I just bought a copy.

I'm presently debating between using Haskell or Clojure for data analysis here at work (or most likely some combination of the two), so the timing couldn't be better.

doorhammer3• 12 years ago

This is a really shallow analysis, and I'm not claiming it's the god given truth. I've been following clojure for awhile, I've listened to--I think--all of Rich Hickey's talks. I've also been recently reading more and more about Haskell. I always come away feeling like they're two of the most "pure" language I've encountered. I don't mean that in a functionally pure way (though there's that too) but ideologically and vision-wise. They both just feel really clean and focussed compared to a lot of languages I use.

I think I lean toward haskell right now just because I'm doing .net full time and doing .net and anything even remotely related java ecosystem at the same time would probably make me crazy. It's my own mental hangup, but there it is.

m0nastic2• 12 years ago

Yeah, I've followed Clojure from afar for the past two years or so, but haven't yet had a reason to use it at work. I like a lot about the way the language is laid out, and whenever I watch one of Rich Hickey's talks I find myself instinctively wanting to sell all my possessions and walk the earth handing out "Data is Code, Code is Data" tracts. The few times it's seemed like Clojure might be a good fit for something small, I've ended up using Racket (for whatever reason I find all the infrastructure around writing and deploying Racket to be less cumbersome than all of Clojure's Java-ness)

So far, I've written all the "collection" type stuff in my system in Haskell, and I'm glad I ignored everyone's hemming and hawing about it, because it was actually a really pleasant experience. Now that I'm gathering a lot of disparate data, I'm in the "what the hell do I do with it?" phase of my project. I'm trying to resist sucking it all into Hadoop (partly because I'm a one-person operation and even a small Hadoop cluster would be larger than all of the systems that are generating the data that I'm monitoring, and partly because I can keep about a years worth of data comfortably in memory).

So I'm basically using this as an opportunity to try out whatever kinds of data analysis I think sound interesting, and then hopefully learning what is a good fit and what isn't. This is all uncharted territory for me, and I'm fortunate to be in a position where I can do what I want and don't have any time pressures.

I figure I can try to use this data to learn about statistical modeling, graph analysis, and machine learning. For the time being, I'm favoring Haskell for this, but that's not really any type of requirement. I just find that I enjoy Haskell a lot right now, so I should see how far I can go before the honeymoon ends and the awfulness is revealed.

GrandTheftR• 12 years ago

I recently did data (log) analysis with Clojure. So far, really enjoyed it. I use gorilla-repl, which is the reason I picked Clojure in the first place. Be able to use (in browser) REPL to play with data, and display table/charts just using Clojure in browser really helps.

I have studied and still a fan of Haskell, only did some small sideline project with Haskell before. Would love to read this book. and maybe use it in the future.

For Clojure, there's the Clojure Data Analysis Cookbook[0] and Clojure for Machine Learning[1]. Both on my reading list.

cfeduke• 12 years ago

There is also the sequel to the Clojure Data Analysis Cookbook, Mastering Clojure Data Analysis[0].

While I don't know for certain I'm going to theorize the Haskell Data Analysis Cookbook began as a Haskell version of the Clojure books since they've were written by a student and professor, respectively, at UVA.

Both of the Clojure books are excellent - you can look at them as a practical hands on way of learning Clojure as an experienced programmer. I'm familiar with Nishant's excellent quality of work so I imagine the Haskell Data Analysis Cookbook would help a curious programmer learn practical Haskell. (I intend to pick up a copy for just this purpose.)

Any plans for a Kindle or other ebook version? This looks like a fun presentation of an interesting topic, but I'd love to read it electronically on a laptop so I can try out the examples.

BinRoo5• 12 years ago

Yup! The eBook is here: http://www.packtpub.com/haskell-data-analysis-cookbook/book

samstokes4• 12 years ago

Thanks! I lazily only clicked through to Amazon and didn't see it there.

I don't know what's involved in getting the Kindle version into Amazon's store, but it might be worth it, as their buying experience is very slick - one click and you're reading the book in 60 seconds.

avitous• 12 years ago

Easy enough to get it onto a Kindle after buying from the Packt site, but +1 to looking into getting it on Amazon's Kindle store as dealing with Packt was less than stellar.

On first visiting Packt site (thru link on your website) the paper+ebook bundle was shown as $43.99, and I sometimes spring for those if they're discounted enough, especially pre-order (as this is, or used to be anyway). On clicking through that to add to cart, it showed up as $54.99, and on going back to original page it now showed price at $54.99 also. Now the eBook showed up as $9.99 (don't recall what it was on original version of page) so I just went for that instead, as that was pretty well discounted... and it shows up as $10.00 when added to the shopping cart, not $9.99. Upon that, on completing purchase they announced a failure to deliver email to my supplied address (very rarely an issue.) hahaha not worth pinging Packt over a $.01 difference, and I suspect the earlier price changing issue might have been a sale promotion that was changing to a different price effective today (publication date?) or thereabouts, and perhaps old versions of the page were being served... but still... good thing Packt takes Paypal as that kind of thing leaves me a bit disinclined to supply them with my CC number...

Anyway, once purchased on Packt's site, they have an 'Email to Kindle' delivery option which worked within a few minutes.

Book looks very interesting, and likely a great way to dive in and learn Haskell. Looking forward to it!

Exciting to see this, but it's painfully clear how much work there is to be done for Haskell to be a competitor to, for example, what is available in Python.

superfunc2• 12 years ago

In what capacity? Speed, ease of use, libraries, safety?

S4M• 12 years ago

libraries. I expect Python and R to have much more available libraries for machine learning than Haskell/

doorhammer3• 12 years ago

Nice! I've been wanting to get further into haskell (I'm a newb with it) and get into some data analysis/machine learning, specifically on text. Going to pick up a copy of this.

losvedir• 12 years ago

Looks very interesting. I briefly skimmed the code samples on GitHub for Chapter 3 (about strings) and was surprised to see no mention of Text or ByteString. Surely those are integral for real world Haskell use when dealing with strings?

BinRoo5• 12 years ago

ByteString and Text are introduced in passing when used in other recipes, but there aren't dedicated recipes for them specifically.

congrats man. time to publish fart app!

samstokes4• 12 years ago

This is an excellent landing page for a technical book. I haven't seen this style before, but the code snippet and details for each chapter gave me a good idea not just of the book's content, but of its emphasis and assumptions.

It suggested that this was a book about solving practical problems (e.g. all the bullet points about file formats, integration points like databases/Twitter/IRC, visualisation), assuming some Haskell knowledge (little time spent on Haskell concepts) but little machine learning knowledge (bullets showed elementary topics like MD5 alongside more advanced topics like perceptual hashing).

Based on this landing page, I bought the book; I probably would not have done so based only on the title and a synopsis.

polymatter• 12 years ago

I just wanted to say I agree entirely with this. It gives me great confidence that this book was well thought out when the chapter by chapter snippets are so clear and concise. I like the drawings too that gives my imagination something to grab onto and breaks it up a little.

mark_l_watson2• 12 years ago

Hello Nishant, I bought the book today and it looks very useful. Thanks! I am in the process of using Haskell for most of my new projects after using Clojure for years.

BinRoo5• 12 years ago

Hi! If you have any questions, please feel free to reach out to me!

hikarudo• 12 years ago

Thank you for writing this! I just bought an ebook copy.

I found it weird that Packt Publishing changed the currency from USD to British pounds when I input my address, which is in Brazil.

Today I published an introductory book on Haskell Data Analysis
