Kuidas võrrelda SAS tulemuslikkuse Julia?

Mul on SAS programmeerija ja arhitekt aastaid: I did my first professional work in the 1990s. I also have made friends among people who focus on SAS. I had mentioned in a SAS Consultants forum in Google Groups that the open source Julia language was delivering impressive results compared with the R language. The testing involves several math problems which could be translated into most any language. Previous results (ja tähis) has been already shared on http://julialang.org/

Ma oleks tahtnud proovida SAS näha kuidas Juliat, but I did not have a machine where I could load both software applications. Aga, Dom Pazzula mitte ainult katsetada seda oma arvutis, but also provided the comparison code. This blog post has the results of the test and the SAS code for you to try the comparison yourself.

Free eBooks from Microsoft

Microsoft Program Manager Eric Ligman has been posting lists of free eBooks from his blog. I have not mentioned these books in past blog postings. So, this posting is a catch-up for the three lists he has already mentioned and subsequently summarized. I will be commenting on free books which help for Microsoft data analytics and data science.

On SPSS parem kui SQL serveri andmete kaevandamine?

Olin hiljuti küsis seda küsimust keegi, kes töötab Microsoft, and who was sincerely trying to understand the differences. I first used SPSS in the early 1990s on the mainframe, just after I had started using SAS on UNIX. Over my career, Olen näinud SPSS erinevates keskkondades, ja olen ka avaldatud raamat ükskord SPSS suvandite stratifitseeritud proovi analüüsi kohta (varem nende ülesannetega ei olnud olemas, kuid nüüd on võimalik valida).

See postitus on minu vastus kuidas hinnata SPSS versus SQL serveri andmete kaevandamine.

I copresented (with Artus Krohn-Grimberghe) a session called “A Best Practices Framework for Data Mining” for the June 13, 2013 PASS Virtual Business Analytics Group.

Tips on Improving WordPress 3.5.1 Speed with GoDaddy Shared Hosting

Päring: How can I improve the performance speed of WordPress with GoDaddy?

Vastus:

I have been happily using WordPress since 2010. I have found myself doing plug-in trial-and-error with different solutions to improve the speed. Anyone could open a blog at wordpress.com and leave the management issues to experts. Aga, I desired to have my blog hosted at marktab.net, so I installed the software myself on a GoDaddy shared Windows hosting platform. The tips I have in this post will likely work also for Linux-based installation, though as with any change, you need to experiment yourself.

In this post, I will be outlining what I did to improve my website speed on http://marktab.net/datamining (running WordPress 3.5.1 on Windows shared hosting at GoDaddy). Consider these tips for any WordPress 3.x version.

I have been using two tools to judge speed. The first one is called Pingdom Tools http://tools.pingdom.com/fpt/ which (praegu) test speeds using one of their three source servers. This test shows how fast a site might load, but I have found the results to be variable (upon repeat tests in the same session with no changes) and I assume likely influenced by the server’s general load and current network traffic. The second, and what I consider better test, comes from Google’s PageSpeed tools https://developers.google.com/speed/pagespeed/. Google is a major source of hits on my domains, and they have been supporting all web developers with a variety of tools to measure traffic. If you are running a website and are not using Google Webmaster tools, you should look at the benefits.

Google’s Page Speed scores websites between 0 ja 100, where higher numbers are better. Their analysis show what the issues are, but how to improve them depends on software used since the service will score any type of website, not just ones running WordPress. Finding out what to do is a matter of trial and error. To achieve my own results I had to try a number of different things given the options available with WordPress 3.5.1 and GoDaddy shared Windows hosting. This post describes a combination which took my WordPress blog from a score in the mid 70′s to over 90.

Tips on Improving DotNetNuke 5 or 7 Speed with GoDaddy Shared Hosting

Päring: How can I improve my speed for DotNetNuke with GoDaddy Shared Hosting?

Vastus:

I have been using DotNetNuke for website hosting since version 4, on both marktab.net and marktab.com. The relationship has been what I have often described as love and hate. Don’t get me wrong: I like the fact that the community edition I use (and which is available at the Microsoft open source website http://dotnetnuke.codeplex.com) is free. Aga, many hands have touched the product, and what we have today is — in my opinion — an eclectic collection of the best content management ideas from different minds and groups.

In this post, I will be outlining what I did to improve my website speed on marktab.net (running DotNetNuke 05.04.04) and marktab.com (running DotNetNuke 07.00.02). I believe these tips would also help DotNetNuke 6, even though I recommend new installations use DotNetNuke 7 or higher.
