VC blog » Blog Archive » Observations on the Manifesto
by karlcow
I like to compare this practice to a game designer who lays out an intended context, rules and narrative for the game, but then has this moment of delight when users engender their own narrative, their own path. This is intrinsic to the conception of Information Visualization as a discovery tool.

Building File Uploaders with PHP 5
by chantal
(via)
My goal here is simply tackling file uploads from a hands-on point of view and discarding all of those additional configuration settings that must be performed in the web server. Therefore, in this series of articles, I’m going to show you how to build some file uploading mechanisms with PHP 5, which, due their intrinsic modularity, can be easily integrated into other existing PHP applications with minor hassles.
Simple SSE optimized sin, cos, log and exp
by ogrisel
I chose to write them in pure SSE1 MMX so that they run on the pentium III of your grand mother, and also on my brave athlon-xp, since thoses beast are not SSE2 aware. Intel AMath showed me that the performance gain for using SSE2 for that purpose was not large enough (10%) to consider providing an SSE2 version (but it can be done very quickly).
The functions use only the _mm_ intrinsics , there is no inline assembly in the code. Advantage: easier to debug, works out of the box on 64 bit setups, let the compiler choose what should be stored in a register, and what is stored in memory. Inconvenient: some versions of gcc 3.x are badly broken with certain intrinsic functions ( _mm_movehl_ps , _mm_cmpeq_ps etc). Mingw's gcc for example -- beware that the brokeness is dependent on the optimization level. A workaround is provided (inline asm replacement for the braindead intrinsics), it is not nice but robust, and broken compilers are detected by the validation program below.
Financial time series forecasting with support vector machines - TeachWiki
by ogrisel
Stock return predictability has been a subject of great controversy. The debate followed issues from market efficiency to the number of factors containing information on future stock returns. The analytical tool of support vector regression on the other hand, has gained great momentum in its ability to predict time series in various applications and also in finance (Smola and Schölkopf, 1998).
The construction of a prediction model requires factors that are believed to have some intrinsic explanatory power. These explanatory factors fall largely into two categories: fundamental and technical. Fundamental factors include for example macroeconimical indicators, which however, are usually only unfrequently published. Technical factors are based solely on the properties of the underlying time series and can therefore be calculated at the same frequency as the time series. Since this study applies support vector regression to high frequent data, only technical factors are considered.

Resurgence Issue 241 - URBAN GARDENS by Satish Kumar
by dggit
(via)
The theme of this issue is urban renewal. Cities are supposed to be the centre of culture, whereas the countryside is seen as the preserve of nature. This is an artificial divide: there is no intrinsic conflict between nature and culture. Indeed, we should bring more nature into our cities. New urban planning is needed. We need small farms, gardens, orchards, ponds and allotments in our cities so that we can participate in the production of vegetables, fruits, milk, cheese and other foods. This will help to reduce food miles and we will enjoy healthy and fresh food in our cities. If people in Havana can have urban gardens and freshly picked sun-ripened fruit, then why can’t the same pleasure be afforded to the citizens of London, New York and New Delhi?

Patterns in Python
by pvergain
What design patterns are applicable to Python? Some patterns are an intrinsic part of Python, other patterns require some careful coding to get the best from them. What new patterns appear in Python?
More Precise Definitions of Intrinsic Widths and Table Layout (Proposal)
by ariels
& 1 other
rules for computing the dimensions of a table or the distribution of column widths within the table were left undefined (for the case when table-layout is auto, the default value), although a non-normative algorithm was presented that depended on two intrinsic widths of a piece of content.

Dr. Dobb's | Regular Expressions in C++ | ] 25, 2001
by YukuanMark
Regular expressions form a central role in many programming languages, including Perl and Awk, as well as many familiar UNIX utilities such as grep and sed. The intrinsic nature of pattern matching in these languages has made them ideally suited to text p
Wired News: The Eternal Value of Privacy
by cbrocas
& 2 others
A future in which privacy would face constant assault was so alien to the framers of the Constitution that it never occurred to them to call out privacy as an explicit right. Privacy was inherent to the nobility of their being and their cause. Of course being watched in your own home was unreasonable. Watching at all was an act so unseemly as to be inconceivable among gentlemen in their day. You watched convicted criminals, not free citizens. You ruled your own home. It's intrinsic to the concept of liberty.

Life Balance software for Palm OS, Macintosh and Windows
by maitrewong
& 4 others
Life Balance is a time and task management program that helps you focus on what`s really important to you and actively balance the often conflicting demands of career and personal life. Life Balance emphasizes the intrinsic importance that you`ve assigned to your projects and life goals, rather than arbitrarily filling every slot in your calendar. This helps you to spend your time and energy on what matters to you the most. You can be self-directed, and know that you are working toward long term goals while still managing your day to day routine.
