I need to draw a tree, and constantly using dotty and including the PNGs is starting to be a pain. Is there a way to get LaTeX to draw it's own trees that doesn't involve learning an entirely new language like TikZ? Its a .vbproj and looks like this  &lt;Project DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"&gt;     &lt;PropertyGroup&gt;         &lt;ProjectGuid&gt;15a7ee82-9020-4fda-a7fb-85a61664692d&lt;/ProjectGuid&gt;   all i want to get is the ProjectGuid but it does not work when a namespace is there...

Do photons truly exist in a physical sense or are they just a useful concept like $i = \sqrt{-1}$? Reading about photons I hear different explanations like "elementary particle", "probability cloud", "energy quanta" and so forth. Since probably no one has ever seen a photon (if "seen" it supposedly - and rather conveniently - ceases to exist) but many experiments seem to verify its properties (or are they maybe adjusted to fit the experiment). I thus can't help wondering if the "photon" is then just a physical/mathematical tool with inexplicable properties (like zero mass - but affected by gravity fields - and constant speed c in space) invented to explain some otherwise unexplainable phenomem and to supplement the elementary particles and their interactions. In short: Are they real or imaginary!  Does anybody know? Or maybe the answer is "blowing in the wind" because to most physicist it probably just does'nt matter as long as it works (as the alternative healers say). Sorry if I seem a little sarcastic here and there. How to merge all scene geometry into a single mesh?

I read that I could create a batch file to net start, net stop the agent and service in a batch file and schedule that, but I was curious if there was a better way of doing this.  Please nevermind how this is indicative of a larger problem of operation, I've been arguing this for a month and we've ended up here.  Thanks :). Creating queries to select by attribute with arcpy I'm quite new with arcpy and I'm finding selecting by attribute a bit of a nightmare. There's a problem with my query on the script below [query = "\'Location\' = observer"], but I can't tell what it is. 'Location' is a field of the feature class I'm dealing with (fc_copy).  with arcpy.da.UpdateCursor(fc_copy,field_names) as cursor:        for row in cursor:         observer = row[0]         arcpy.MakeFeatureLayer_management(fc_copy, 'fl_copy_OBS')         arcpy.MakeFeatureLayer_management(fc_copy, 'fl_copy_TAR')         query = "\'Location\' = observer"         arcpy.SelectLayerByAttribute_management('fl_copy_OBS', 'NEW_SELECTION', query)         arcpy.SelectLayerByAttribute_management('fl_copy_TAR', 'NEW_SELECTION', query, invert_where_clause = 'INVERT')   This is the error I get => Invalid expression                            Failed to execute (SelectLayerByAttribute).  Is there any documentation to learn the rules to follow to build queries for arcpy? LaTeX baffled by BOM---Unicode's byte order mark. Unicode applies the convention of using a  as signature at the beginning of a text stream, identifying the encoding used within it. The following three bytes at the beginning of a file: EF BB BF, identifies this file as a UTF8 file. Vi and most text editors gracefully ignore this signature. Open office does that as well, but it adds this signature at the beginning.  Now, if I open a TeX file with OpenOffic.org, and I do that quite a lot (for mixed directionality editing), the signature is added, and baffles LaTeX, which produces an error message such as:   !

I have a folder ExampleFolder which contains many zipped folders. These zipped folders also contains multiple zipped folders. How to go through ExampleFolder and extract all of its zipped folders recursively?   Note that ExampleFolder itself, is not zipped, it's just a normal folder  Okay now I know what's happening Rinzwind and nux answers are both correct (except that I have to keep pressing Y or A forever)  But it's seems that some of the zipped files, contained zipped files and rar files as well, the rar files will not be extracted by   while [ "`find . -type f -name '*.zip' | wc -l`" -gt 0 ]; do find -type f -name "*.zip" -exec unzip -- '{}' \; -exec rm -- '{}' \;; done    or whatever  Edit 2 Some files are named .r00 and r01, .r02 up to r14, they are rar files, but not .rar I'm doing a masters course at a different university than I did my undergrad (both in maths). I did well in my undergrad but now I'm finding it very difficult. The shock of the change is hard to cope with.  I'm not just finding it very difficult, but I get zero feedback: we don't have any tests and I was not able to make friends so I don't know how others are finding it. I'm starting to think that I might be an idiot.   How can I build some confidence in my abilities at the same time as I rush and struggle to keep up with the massive rate of new material I need to learn? How might I get myself some reassurance that I can actually pass, or stop worrying about this so much? (I feel terribly guilty using so much money from my family to be here) It's possible that I don't really have a chance at all but knowing that would be fine.

When writing a book and referring to a female and male aged 18–25, what term would be most appropriate? Boy and girl seem too young, whereas man and woman seem too old.

Can an integrated HDMI port work both ways? Say I had a laptop [Correction: notebook, don't want my thighs medium rare], any OS, and it has an HDMI port built into the side. Would it be remotely possible to hack it into an input, provided it wasn't already designed for that? I would figure all video ports operate straight off the graphics chip, however, are there ways to override that functionality on the driver level? Driver hacks already exist for plenty of things such as the classic example: Bluetooth adapters (so we can play with our PS3 controllers and save a buck) However, is HDMI one of these tamperable interfaces? As far as the interface standard is concerned, are HDMI ports designed to be either way or are they Input/Output specific?
