Why don't we see fork boots anymore? When I was younger, it seemed most mountain bike shocks had rubber boots on them, but now most seem to be "naked."    How important were the shock protectors that covered the exposed part of the piston - either the generic rubber boots or the neoprene "lizard" protectors? Did they make a difference for most riding styles?   Why has naked become the new thing? Is this just value-engineering?    And is there any meaningful difference in performance between the two?
Why do modern mountain bike forks no longer use boots on fork stanchions? Why do modern mountain bike forks no longer use boots on fork stanchions? Older mountain bikes used to have them on the forks, and lefty and headshocks still do. Why have these fallen out of fashion and would putting aftermarket fork boots on your stanchions be productive or not?
Erasing a Linux laptop I have a laptop with Debian on it, and I am going to sell this laptop.   Would it suffice to erase the Debian installation before selling it to completely clean up my laptop from my personal data, and if yes how can I uninstall Debian (so that there isn't any operating system on the laptop)? Recovering Outlook .pst password? I am trying to recover an Outlook .pst file password.  Is there some way to do this?  I am using Outlook 2007 and Windows 7.

Question :   Determine all natural numbers n such that 3   divides $n\cdot2^{n}+1$  Actually I don't have any ideas to approach but  my efforts :   I see $n=1,2,7,8,13,14$ so I think :   $n=6k+1$ and $n=6k+2$ $k\in \Bbb{N} $  If I'm not wrong but I don't know how ? I prove it ? How can I raise a soldiers hacking ability? My main specialist seems to have a hard time hacking stuff. How can I make him better at it? Is acceleration due to gravity constant? What is safe to exclude for a full system backup? I'm new to modelbuilder and python. I have used modelbuilder to iterate through all rows in a shapefile (Points), process them, and produce a seperate output shapefile for each row.  The filename is generated using an inline variable (I think that is the correct terminology).  i.e. all output files have identical filenames except that the value of the PointID from the original input file is appended to the filename to enable them to be distinguished.  This works fine.  I've also written a python script to take the above output files from the model one at a time and do additional processing.  At present the input filename is hard coded into the script (i.e. I have to edit the script to change the input filename each time I run it).  Again this works fine while just processing a single file. However, I want to integrate the model and the python script so that I can run the script for each row in the original feature class automatically.  My question is therefore, how do I replace the hard coded name of the input file with a variable in the python script and how do I pass the filename to the script. Can I award user with special bounty after accepting his anwer? I have a , and I haven't start a bounty for this question. After I got my answer I'd like to give a user a special bounty, because I consider his answer very helpful and it saved me a lot of time. I've already accepted the answer. Is there a way how can I give him some bounty?  Thank you Can I safely connect the power-only-end of a USB-Y cable to an other power source? If the host computer for an USB device doesn't provide enough power for a device which has no dedicated power port, can I connect the power-only-plug of a Y-USB-cable to an other computer, an USB-charger or even a regular mobile charger? I'm afraid this could damage some of the devices.  Edit: The device in question is a USB Hard drive (Samsung S2 Portable 640GB (but on the back it's written to use 0.85A)) which is supposed to work whit just a single USB port. It did so well on a other laptop and whit some cables even on my actual net book back in Europe. But now in Malaysia it works only some times (I still try to figure out what the conditions are) and then it stops working after a while (maybe when it goes to power save mode). I heard from others their hard drives need one more power plug here in Malaysia to but can't imagine why... Probability that the sum of 6 dice rolls is even I am currently learning electromagnetism and I am getting really annoyed using a physical hand to accomplish the right hand rule. I get it, i've seen diagrams, and i've solved problems with it but still somehow I mess up because I bend a finger or twist my wrist a strange way. I am tired of using my hand.  So my question is can I find an entirely mathematical basis for this?  Lets say for any given diagram I define the positive $x$ axis as going to the right, the positive $y$ axis as going up and the positive $z$ axis as going into the page. Then I just did unit vectors for everything to determine the missing component?  As I understand it $\vec{F} = q (\vec{V}\times\vec{B})$ and with that definition I am confident I could find out the direction of the electric field given the velocity of a particle of charge and the magnetic field but how can I re-arrange this so I can solve for other variables? For example what does $\vec{B}$ equal in terms of a cross product involving $\vec{V}$ and $\vec{F}$? What would I prefer - an over-fitted model or a less accurate model? Let's say we have two models trained. And let's say we are looking for good accuracy.  The first has an accuracy of 100% on training set and 84% on test set. Clearly over-fitted. The second has an accuracy of 83% on training set and 83% on test set.   On the one hand, model #1 is over-fitted but on the other hand it still yields better performance on an unseen test set than the good general model in #2.   Which model would you choose to use in production? The First or the Second and why? Positive correlation and negative regressor coefficient sign Is it possible to obtain a positive correlation between a regressor and a response (+0,43) and, after that, obtain a negative coefficient in the fitted regression model for this regressor?  I'm not talking about changes in the sign of the regressor among some models. The coefficient sign always remains.  Could  the remaining variables of the fitted model influence the changing of the sign? Creating polyline-based "heatmap" from GPS tracks? This winter I am planning to track my downhill skiing/snowboarding using a GPS.  Most of my riding will occur at the same resort.  I would like to be able to create a sort of "heatmap" that shows the amount of runs that I have made in a given area.  As I add more and more GPS traces to my database, my goal would be to see a sort of linear heatmap of the most traveled areas.  Given the nature of downhill skiing, you would expect the uphill chairlift lines will be the "hottest" because it will be the only places visited over-and-over again.  Given that 1) my track will not be the same every time and 2) the area covered by following one "run" may be a few hundred feet wide, what might be the best way to analyze this "linear" data to create a sort of heatmap?  My thoughts were to buffer the lines, then intersect the polys to get a sort of Venn Diagram thing going.  My preference is to use open-source technologies.  I've got QGIS and PostGIS loaded and available.  UPDATE: In regards to @blah238's response, I was thinking of something that might be able to "collect" the number of passes ("runs") through an area, and then symbolize by the count.  Conceptually, this would be similar to ArcGIS "" (but for lines, not points) or  (but for multiple line in roughly the same area).  A more visual example of a similar concept might be a traffic-flow map, where highly-congested areas would equate to "highly-traveled" ski runs/areas:    I've read the following questions that may give some ideas, but they don't really address what I am trying to accomplish: Dell R730xd - Best way to configure storage for simultaneous use with ZFS & Hardware RAID I recently purchased a Dell R730xd that came with an H730 RAID card. I would like to bring an existing 6 disk ZFS pool to this server as well as create an additional 6 disk hardware RAID.   Is it possible to configure an H730 RAID card to operate in both HBA and RAID mode simultaneously? And then only manage 6 of the disks in a hardware RAID and allow the OS to manage the remaining 6 disks in a software RAID?  If not, can a Dell R730xd use both an H730 RAID card and an LSI 9207-8i HBA card simultaneously? Would you simply plug one SAS cable from each card into each part of the Backplane? Will I need to purchase any new cables to connect the LSI 9207-8i to the backplane in my R730xd?  Is there a better card to use for ZFS in an R730xd using spinning disks than the LSI 9207-8i?
