How to fix: Windows 7 loads default instead of user-modified profile wiping off all settings, files, email accounts, bookmarks

I repeatedly run into the “default user profile instead of my user settings” problem with Windows 7. Once in a while when I log in onto my user profile on my Win 7 computer, it logs into default user profile and all my settings in web browsers, office files and other software is gone! MS Outlook asks me to set up all the email accounts over again! My documents directory is empty, but all files still can be found in C:\\Users\myusername… So what is the problem and how to fix it quickly? Last time it happened I googled solution and quickly learned that this is pretty common problem for Windows 7, and the only fix is to edit Registry. Now as it happen again this morning I could not found exact instructions on the web again, so after frantic searching for solution (and finally fixing my PC), I decided to post it on my blog in IT tips section… 

One of the people posted in a forum, almost as an after-thought, all tucked away where, if you didn’t take the time to read thoroughly, you’d miss it:

“I solved my problem by going into the registry and delete the effected profile’s subfolder under:

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList”

Note: HKLM refers to “HKEY_LOCAL_MACHINE” in the registry.

DIY: Setup Zotero - free open source publication and citation manager

Zotero [zoh-TAIR-oh] is a free, easy-to-use tool to help you collect, organize, cite, and share your research sources. It lives right where you do your research — in the web browser itself. You can use it to quickly grab and re-use citation from our public library “Soil Electrical Geophysics”.

A personal research assistant!

Zotero is the only research tool that automatically senses content, allowing you to add it to your personal library with a single click. Whether you're searching for a preprint on arXiv.org, a journal article from JSTOR, a news story from the New York Times, or a book from university’s or public library catalog, Zotero has you covered with support for thousands of sites.

  • Grab your research with a single click.
  • Store it privately or share with collaborators.
  • Select multiple sources and insert formatted reference list in your paper/report while writing it (MS Word plugin).
  • Store anything:

Zotero collects all your research in a single, searchable interface. You can add PDFs, images, audio and video files, snapshots of web pages, and really anything else. Zotero automatically indexes the full-text content of your library, enabling you to find exactly what you're looking for with just a few keystrokes.

Soil Electrical Geophysics - public library @Zotero

Landviser maintains public library of publications related to "Soil Electrical Geophysics" on Zotero servers. You can view and browse that library below. PDFs of publications in public domain are attached to the respective listings in the library and are stored on this website. For most publications registration on Zotero or our website is not required, although we are strongly encourage you to register to gain access to all materials, receive timely updates and easily manage your own research library.

RES3DINV - 3D inversion geophysical software for resistivity and induced polarization data

Multi-core support with RES3DINVx32, 128GB memory support with RES3DINVx64

RES2DINV - 2D Geophysical Inversion Software for Resistivity and Induced Polarization data

Supports on land, underwater and cross-borehole surveysRES2DINV with topography

Supports the Wenner (alpha,beta,gamma), Wenner-Schlumberger, pole-pole, pole-dipole, inline dipole-dipole, equatorial dipole-dipole, gradient and non-conventional arrays. 
Supports exact and approximate least-squares optimisation methods 
Supports smooth and sharp constrasts inversions 
Supports up to 16000 electrodes and 21000 data points on computers with 1GB RAM 
Seamless inversion of very long survey lines using sparse inversion techniques 
(RES2DINV only license includes limited used of RES3DINV 3D inversion program)

RES2DINV software is designed to interpolate and interpret field data of electrical geophysical prospecting (2D sounding) of electrical resistivity (conductivity) and induced polarization. The inversion of the resistivity and IP data is conducted by least-square method involving finite-element and finite-difference methods. The software can handle data from any electrode array, including Wenner (a, b, g), dipole-dipole, inline pole-dipole, pole-pole, Wenner-Schlumberger, equatorial pole-dipole and non-conventional arrays. Interpolate data from land, under water, and cross-borehole surveys. Easy data conversion from the most popular geophysical instruments including ABEM  Lund, Syskal, AGI, PASI, IRIS, SCITREX, etc.
