Ich habe ein SAS-Programmierer und Architekt seit Jahren: 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 (und code) has been already shared on http://julialang.org/ Ich wollte versuchen SAS um zu sehen, wie es gegen Julia macht, but I did not have a machine where I could load both software applications. Jedoch, Dom Pazzula getestet es nicht nur auf seinem Rechner, 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. Lesen Sie weiter “Wie vergleicht sich SAS-Leistung mit Julia?” Ich war vor kurzem diese Frage von jemandem gestellt, die für Microsoft arbeitet, 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, Ich habe SPSS in verschiedenen Umgebungen, und ich auch ein Papier einmal über SPSS Optionen für geschichtete Stichprobe Analyse veröffentlicht (zuvor diese Funktionen nicht verfügbar waren, aber jetzt sind sie als Option erhältlich). Dieser Beitrag wird meine Antwort auf wie SPSS versus SQL Server Data Mining zu bewerten haben..

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. Jedoch, 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/ die (aktuell) 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 und 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. Lesen Sie weiter “Tips on Improving WordPress 3.5.1 Speed with GoDaddy Shared Hosting” » Query: How can I improve my speed for DotNetNuke with GoDaddy Shared Hosting? Response: 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. Jedoch, 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. I have been using two tools to judge speed.

This post has the details. Lesen Sie weiter “How can I find work in Microsoft data mining?” Over time I have earned a number of Microsoft Certifications, and Microsoft is among several vendors who offer certification. In this post, I discuss my opinion about the overall value of certification (in general) and Microsoft certification (in particular). I also provide scenarios for when certification will not help advance your professional career. I ask and answer three questions in this post: - When does certification help? - When does certification not help? - Do certifications mean you are done?

The app was only listing some of the installed programs. I mentioned that he could use PowerShell for the same task. And on the way, I discovered a reason why apps (and even some PowerShell scripts) might only report a subset of the full list of installed programs. Query: How can someone list installed Windows programs using PowerShell? Response: Lesen Sie weiter “Determining Installed Windows Programs with PowerShell” » A SQL Server expert asked me a question last February about time series (forecasting) and performance. I ask other experts all the time about questions I have, and I enjoy answering questions that people send me. I have not blogged about some of these questions, but I will be emptying my email box from these past questions because I believe others might benefit from the answers. I have decided to add a new category to my blog called “Abfrage und Antwort”. The expected title would be “Question and Answer” but I like my redesigned phrasing better, since it’s more culturally relevant to SQL Server people. Also, the title change gives me permission to just give a best response in cases where I don’t have an answer (relevant when the discussion is ongoing, and also cases where more investigation is needed). Query: Hi Mark, Was hoping you could point me in right direction. I’ve got a Microsoft Data Mining implementation that uses the Microsoft Time Series to predict order quantities for the next 14 days for product by store (roughly 15,911 unique store/product combinations). Problem is the query runs terrible, takes it about 30 hours to process. Need to get that run time down, was hoping you might be able to point me to some resources to do performance tuning on data mining queries. Thanks Response: Thanks for asking. This reply comes in two parts: part one focuses on the construct (SQL Server Analysis Services, SSAS), and part two focuses on the content (time series modeling).

Nemojte me pogrešno shvatiti: Sviđa mi se činjenica da je Community Edition koristim (a koji je dostupan na Microsoft open source web stranicu http://dotnetnuke.codeplex.com) je slobodan.
