13.5 Reading POP EmailSo far, we've stepped through the path the system follows to send new mail. Let's now see what happens when we try to view incoming POP mail. 13.5.1 The POP Password PageIf you flip back to the main page in Figure 13-2, you'll see a View link; pressing it triggers the script in Example 13-6 to run on the server: Example 13-6. PP2E\Internet\Cgi-Web\PyMailCgi\onRootViewLink.cgi#!/usr/bin/python ############################################################## # on view link click on main/root html page # this could almost be a html file because there are likely # no input params yet, but I wanted to use standard header/ # footer functions and display the site/user names which must # be fetched; On submission, doesn't send the user along with # password here, and only ever sends both as URL params or # hidden fields after the password has been encrypted by a # user-uploadable encryption module; put html in commonhtml? ############################################################## # page template pswdhtml = """ <form method=post action=%s/onViewPswdSubmit.cgi>
 Please enter POP account password below, for user "%s" and site "%s".
<input name=pswd type=password> <input type=submit value="Submit"></form>

Security note: The password you enter above will be transmitted over the Internet to the server machine, but is not displayed, is never transmitted in combination with a username unless it is encrypted, and is never stored anywhere: not on the server (it is only passed along as hidden fields in subsequent pages), and not on the client (no cookies are generated). This is still not totally safe; use your browser's back button to back out of PyMailCgi at any time.
 """ # generate the password input page import commonhtml # usual parms case: user, pswd, site = commonhtml.getstandardpopfields({}) # from module here, commonhtml.pageheader(kind='POP password input') # from html|url later print pswdhtml % (commonhtml.urlroot, user, site) commonhtml.pagefooter( ) This script is almost all embedded HTML: the triple-quoted pswdhtml string is printed, with string formatting, in a single step. But because we need to fetch the user and server names to display on the generated page, this is coded as an executable script, not a static HTML file. Module commonhtml either loads user and server names from script inputs (e.g., appended to the script's URL), or imports them from the mailconfig file; either way, we don't want to hardcode them into this script or its HTML, so an HTML file won't do. Since this is a script, we can also make use of the commonhtml page header and footer routines to render the generated reply page with the common look-and-feel; this is shown in Figure 13-7. Figure 13-7. PyMailCgi view password login pageAt this page, the user is expected to enter the password for the POP email account of the user and server displayed. Notice that the actual password isn't displayed; the input field's HTML specifies type=password, which works just like a normal text field, but shows typed input as stars. (See also Example 11-6 for doing this at a console, and Example 11-23 for doing this in a GUI.) 13.5.2 The Mail Selection List PageAfter filling out the last page's password field and pressing its Submit button, the password is shipped off to the script shown in Example 13-7. Example 13-7. PP2E\Internet\Cgi-Web\PyMailCgi\onViewPswdSubmit.cgi#!/usr/bin/python # On submit in pop password input window--make view list import cgi, StringIO, rfc822, string import loadmail, commonhtml from secret import encode # user-defined encoder module MaxHdr = 35 # max length of email hdrs in list # only pswd comes from page here, rest usually in module formdata = cgi.FieldStorage( ) mailuser, mailpswd, mailsite = commonhtml.getstandardpopfields(formdata) try: newmail = loadmail.loadnewmail(mailsite, mailuser, mailpswd) mailnum = 1 maillist = [] for mail in newmail: msginfo = [] hdrs = rfc822.Message(StringIO.StringIO(mail)) for key in ('Subject', 'From', 'Date'): msginfo.append(hdrs.get(key, '?')[:MaxHdr]) msginfo = string.join(msginfo, ' | ') maillist.append((msginfo, commonhtml.urlroot + '/onViewListLink.cgi', {'mnum': mailnum, 'user': mailuser, # data params 'pswd': encode(mailpswd), # pass in url 'site': mailsite})) # not inputs mailnum = mailnum+1 commonhtml.listpage(maillist, 'mail selection list') except: commonhtml.errorpage('Error loading mail index') This script's main purpose is to generate a selection list page for the user's email account, using the password typed into the prior page (or passed in a URL). As usual with encapsulation, most of the details are hidden in other files:
The maillist list built here is used to create the body of the next page -- a clickable email message selection list. Each generated hyperlink in the list page references a constructed URL that contains enough information for the next script to fetch and display a particular email message. If all goes well, the mail selection list page HTML generated by this script is rendered as in Figure 13-8. If you get as much email as I do, you'll probably need to scroll down to see the end of this page. It looks like Figure 13-9, and follows the common look-and-feel for all PyMailCgi pages, thanks to commonhtml. Figure 13-8. PyMailCgi view selection list page, topFigure 13-9. PyMailCgi view selection list page, bottomIf the script can't access your email account (e.g., because you typed the wrong password), then its try statement handler instead produces a commonly formatted error page. Figure 13-10 shows one that gives the Python exception and details as part of the reply after a genuine exception is caught. Figure 13-10. PyMailCgi login error page<IP_ADDRESS> Passing state information in URL link parametersThe central mechanism at work in Example 13-7 is the generation of URLs that embed message numbers and mail account information. Clicking on any of the View links in the selection list triggers another script, which uses information in the link's URL parameters to fetch and display the selected email. As mentioned in the prior chapter, because the list's links are effectively programmed to "know" how to load a particular message, it's not too far-fetched to refer to them as smart links -- URLs that remember what to do next. Figure 13-11 shows part of the HTML generated by this script. Figure 13-11. PyMailCgi view list, generated HTMLDid you get all that? You may not be able to read generated HTML like this, but your browser can. For the sake of readers afflicted with human parsing limitations, here is what one of those link lines looks like, reformatted with line breaks and spaces to make it easier to understand:
<ahref="http://starship.python.net/~lutz/ PyMailCgi/onViewListLink.cgi ?user=lutz& mnum=66& pswd=%8cg%c2P%1e%f3%5b%c5J%1c%f0& site=pop.rmi.net">View 66 test sendurl.py |<EMAIL_ADDRESS>| Mon Jun 5 17:51:11 2000 PyMailCgi generates fully specified URLs (with server and pathname values imported from a common module). Clicking on the word "View" in the hyperlink rendered from this HTML code triggers the onViewListLink script as usual, passing it all the parameters embedded at the end of the URL: POP username, the POP message number of the message associated with this link, and POP password and site information. These values will be available in the object returned by cgi.FieldStorage in the next script run. Note that the mnum POP message number parameter differs in each link because each opens a different message when clicked, and that the text after  comes from message headers extracted with the rfc822 module. The commonhtml module escapes all of the link parameters with the urllib module, not cgi.escape, because they are part of a URL. This is obvious only in the pswd password parameter -- its value has been encrypted, but urllib additionally escapes non-safe characters in the encrypted string per URL convention (that's where all those %xx come from). It's okay if the encryptor yields odd -- even non-printable -- characters, because URL encoding makes them legible for transmission. When the password reaches the next script, cgi.FieldStorage undoes URL escape sequences, leaving the encrypted password string without % escapes. It's instructive to see how commonhtml builds up the smart link parameters. Earlier, we learned how to use the urllib.quote_plus call to escape a string for inclusion in URLs: >>> import urllib >>> urllib.quote_plus("There's bugger all down here on Earth") 'There%27s+bugger+all+down+here+on+Earth' Module commonhtml, though, calls the higher-level urllib.urlencode function, which translates a dictionary of name:value pairs into a complete URL parameter string, ready to add after a ? marker in a URL. For instance, here is urlencode in action at the interactive prompt: >>> parmdict = {'user': 'Brian', ... 'pswd': '#!/spam', ... 'text': 'Say no more, squire!'} >>> urllib.urlencode(parmdict) 'pswd=%23%21/spam&user=Brian&text=Say+no+more,+squire%21' >>> "%s?%s" % ("http://scriptname.cgi", urllib.urlencode(parmdict)) 'http://scriptname.cgi?pswd=%23%21/spam&user=Brian&text=Say+no+more,+squire%21' Internally, urlencode passes each name and value in the dictionary to the built-in str function (to make sure they are strings) and then runs each one through urllib.quote_plus as they are added to the result. The CGI script builds up a list of similar dictionaries and passes it to commonhtml to be formatted into a selection list page.[2]
In broader terms, generating URLs with parameters like this is one way to pass state information to the next script (along with databases and hidden form input fields, discussed later). Without such state information, the user would have to re-enter the username, password, and site name on every page they visit along the way. We'll use this technique again in the next case study, to generate links that "know" how to fetch a particular database record. Incidentally, the list generated by this script is not radically different in functionality from what we built in the PyMailGui program of Chapter 11. Figure 13-12 shows this strictly client-side GUI's view on the same email list displayed in Figures Figure 13-8 and Figure 13-9. Figure 13-12. PyMailGui displaying the same view listHowever, PyMailGui uses the Tkinter GUI library to build up a user interface instead of sending HTML to a browser. It also runs entirely on the client and downloads mail from the POP server to the client machine over sockets on demand. In contrast, PyMailCgi runs on the server machine and simply displays mail text on the client's browser -- mail is downloaded from the POP server machine to the starship server, where CGI scripts are run. These architecture differences have some important ramifications, which we'll discuss in a few moments. <IP_ADDRESS> Security protocolsIn onViewPswdSubmit's source code (Example 13-7), notice that password inputs are passed to an encode function as they are added to the parameters dictionary, and hence show up encrypted in hyperlink URLs. They are also URL-encoded for transmission (with % escapes) and are later decoded and decrypted within other scripts as needed to access the POP account. The password encryption step, encode, is at the heart of PyMailCgi's security policy. Beginning in Python 1.6, the standard socket module will include optional support for OpenSSL, an open source implementation of secure sockets that prevents transmitted data from being intercepted by eavesdroppers on the Net. Unfortunately, this example was developed under Python 1.5.2 and runs on a server whose Python did not have secure socket support built in, so an alternative scheme was devised to minimize the chance that email account information could be stolen off the Net in transit. Here's how it works. When this script is invoked by the password input page's form, it gets only one input parameter: the password typed into the form. The username is imported from a mailconfig module installed on the server instead of transmitted together with the unencrypted password (that would be much too easy for malicious users to intercept). To pass the POP username and password to the next page as state information, this script adds them to the end of the mail selection list URLs, but only after the password has been encrypted by secret.encode -- a function in a module that lives on the server and may vary in every location that PyMailCgi is installed. In fact, PyMailCgi was written to not have to know about the password encryptor at all; because the encoder is a separate module, you can provide any flavor you like. Unless you also publish your encoder module, the encoded password shipped with the username won't be of much help to snoopers. That upshot is that normally, PyMailGui never sends or receives both user and password values together in a single transaction unless the password is encrypted with an encryptor of your choice. This limits its utility somewhat (since only a single account username can be installed on the server), but the alternative of popping up two pages -- one for password entry and one for user -- is even more unfriendly. In general, if you want to read your mail with the system as coded, you have to install its files on your server, tweak its mailconfig.py to reflect your account details, and change its secret.py encryptor as desired. One exception: since any CGI script can be invoked with parameters in an explicit URL instead of form field values, and since commonhtml tries to fetch inputs from the form object before importing them from mailconfig, it is possible for any person to use this script to check his or her mail without installing and configuring a copy of PyMailCgi. For example, a URL like the following (but without the linebreak used to make it fit here): http://starship.python.net/~lutz/PyMailCgi/ onViewPswdSubmit.cgi?user=lutz&pswd=asif&site=pop.rmi.net will actually load email into a selection list using whatever user, password, and mail site names are appended. From the selection list, you may then view, reply, forward, and delete email. Notice that at this point in the interaction, the password you send in a URL of this form is not encrypted. Later scripts expect that the password inputs will be sent encrypted, though, which makes it more difficult to use them with explicit URLs (you would need to match the encrypted form produced by the secret module on the server). Passwords are encrypted as they are added to links in the reply page's selection list, and remain encrypted in URLs and hidden form fields thereafter.
13.5.3 The Message View PageBack to our page flow. At this point, we are still viewing the message selection list in Figure 13-8. When we click on one of its generated hyperlinks, the smart URL invokes the script in Example 13-8 on the server, sending the selected message number and mail account information (user, password, and site) as parameters on the end of the script's URL. Example 13-8. PP2E\Internet\Cgi-Web\PyMailCgi\onViewListLink.cgi#!/usr/bin/python ############################################################ # On user click of message link in main selection list; # cgi.FieldStorage undoes any urllib escapes in the link's # input parameters (%xx and '+' for spaces already undone); ############################################################ import cgi, rfc822, StringIO import commonhtml, loadmail from secret import decode #commonhtml.dumpstatepage(0) form = cgi.FieldStorage( ) user, pswd, site = commonhtml.getstandardpopfields(form) try: msgnum = form['mnum'].value # from url link newmail = loadmail.loadnewmail(site, user, decode(pswd)) textfile = StringIO.StringIO(newmail[int(msgnum) - 1]) # don't eval! headers = rfc822.Message(textfile) bodytext = textfile.read( ) commonhtml.viewpage(msgnum, headers, bodytext, form) # encoded pswd except: commonhtml.errorpage('Error loading message') Again, most of the work here happens in the loadmail and commonhtml modules, which are listed later in this section (Example 13-12 and Example 13-14). This script adds logic to decode the input password (using the configurable secret encryption module) and extract the selected mail's headers and text using the rfc822 and StringIO modules, just as we did in Chapter 11.[3]
If the message can be loaded and parsed successfully, the result page (shown in Figure 13-13) allows us to view, but not edit, the mail's text. The function commonhtml.viewpage generates a "read-only" HTML option for all the text widgets in this page. Figure 13-13. PyMailCgi view pageView pages like this have a pull-down action selection list near the bottom; if you want to do more, use this list to pick an action (Reply, Forward, or Delete), and click on the Next button to proceed to the next screen. If you're just in a browsing frame of mind, click the "Back to root page" link at the bottom to return to the main page, or use your browser's Back button to return to the selection list page. <IP_ADDRESS> Passing state information in HTML hidden input fieldsWhat you don't see on the view page in Figure 13-13 is just as important as what you do. We need to refer to Example 13-14 for details, but there's something new going on here. The original message number, as well as the POP user and (still encrypted) password information sent to this script as part of the smart link's URL, wind up being copied into the HTML used to create this view page, as the values of "hidden" input fields in the form. The hidden field generation code in commonhtml looks like this: print '<form method=post action="%s/onViewSubmit.cgi">' % urlroot print '<input type=hidden name=mnum value="%s">' % msgnum print '<input type=hidden name=user value="%s">' % user # from page|url print '<input type=hidden name=site value="%s">' % site # for deletes print '<input type=hidden name=pswd value="%s">' % pswd # pswd encoded Much like parameters in generated hyperlink URLs, hidden fields in a page's HTML allow us to embed state information inside this web page itself. Unless you view that page's source, you can't see this state information, because hidden fields are never displayed. But when this form's Submit button is clicked, hidden field values are automatically transmitted to the next script along with the visible fields on the form. Figure 13-14 shows the source code generated for a different message's view page; the hidden input fields used to pass selected mail state information are embedded near the top. Figure 13-14. PyMailCgi view page, generated HTMLThe net effect is that hidden input fields in HTML, just like parameters at the end of generated URLs, act like temporary storage areas and retain state between pages and user interaction steps. Both are the Web's equivalent to programming language variables. They come in handy any time your application needs to remember something between pages. Hidden fields are especially useful if you cannot invoke the next script from a generated URL hyperlink with parameters. For instance, the next action in our script is a form submit button (Next), not a hyperlink, so hidden fields are used to pass state. As before, without these hidden fields, users would need to re-enter POP account details somewhere on the view page if they were needed by the next script (in our example, they are required if the next action is Delete). <IP_ADDRESS> Escaping mail text and passwords in HTMLNotice that everything you see on the message view page in Figure 13-13 is escaped with cgi.escape. Header fields and the text of the mail itself might contain characters that are special to HTML and must be translated as usual. For instance, because some mailers allow you to send messages in HTML format, it's possible that an email's text could contain a </textarea> tag, which would throw the reply page hopelessly out of sync if not escaped. One subtlety here: HTML escapes are important only when text is sent to the browser initially (by the CGI script). If that text is later sent out again to another script (e.g., by sending a reply), the text will be back in its original, non-escaped format when received again on the server. The browser parses out escape codes and does not put them back again when uploading form data, so we don't need to undo escapes later. For example, here is part of the escaped text area sent to a browser during a Reply transaction (use your browser's View Source option to see this live):
Text: <textarea name=text cols=80 rows=10 readonly> more stuff --Mark Lutz (http://rmi.net/~lutz) [PyMailCgi 1.0] > -----Original Message----- > From<EMAIL_ADDRESS>> To<EMAIL_ADDRESS>> Date: Tue May 2 18:28:41 2000 > >
<textarea> > </textarea>
 > --Mark Lutz (http://rmi.net/~lutz) [PyMailCgi 1.0] > > > > -----Original Message----- After this reply is delivered, its text looks as it did before escapes (and exactly as it appeared to the user in the message edit web page): more stuff --Mark Lutz (http://rmi.net/~lutz) [PyMailCgi 1.0] > -----Original Message----- > From<EMAIL_ADDRESS>> To<EMAIL_ADDRESS>> Date: Tue May 2 18:28:41 2000 > >
<textarea> > </textarea>
 > --Mark Lutz (http://rmi.net/~lutz) [PyMailCgi 1.0] > > > > -----Original Message----- Did you notice the odd characters in the hidden password field of the generated HTML screen shot (Figure 13-14)? It turns out that the POP password is still encrypted when placed in hidden fields of the HTML. For security, they have to be: values of a page's hidden fields can be seen with a browser's View Source option, and it's not impossible that the text of this page could be intercepted off the Net. The password is no longer URL-encoded when put in the hidden field, though, even though it was when it appeared at the end of the smart link URL. Depending on your encryption module, the password might now contain non-printable characters when generated as a hidden field value here; the browser doesn't care, as long as the field is run through cgi.escape like everything else added to the HTML reply stream. The commonhtml module is careful to route all text and headers through cgi.escape as the view page is constructed. As a comparison, Figure 13-15 shows what the mail message captured in Figure 13-13 looks like when viewed in PyMailGui, the client-side Tkinter-based email tool from Chapter 11. PyMailGui doesn't need to care about things like passing state in URLs or hidden fields (it saves state in Python variables) or escaping HTML and URL strings (there are no browsers, and no network transmission steps once mail is downloaded). It does require Python to be installed on the client, but we'll get into that in a few pages. Figure 13-15. PyMailGui viewer, same message13.5.4 The Message Action PagesAt this point in our hypothetical PyMailCgi web interaction, we are viewing an email message (Figure 13-13) that was chosen from the selection list page. On the message view page, selecting an action from the pull-down list and clicking the Next button invokes the script in Example 13-9 on the server to perform a reply, forward, or delete operation for the selected message. Example 13-9. PP2E\Internet\Cgi-WebPyMaiCgi\onViewSubmit.cgi#!/usr/bin/python # On submit in mail view window, action selected=(fwd, reply, delete) import cgi, string import commonhtml, secret from externs import pymail, mailconfig from commonhtml import getfield def quotetext(form): """ note that headers come from the prior page's form here, not from parsing the mail message again; that means that commonhtml.viewpage must pass along date as a hidden field """ quoted = '\n-----Original Message-----\n' for hdr in ('From', 'To', 'Date'): quoted = quoted + '%s: %s\n' % (hdr, getfield(form, hdr)) quoted = quoted + '\n' + getfield(form, 'text') quoted = '\n' + string.replace(quoted, '\n', '\n> ') return quoted form = cgi.FieldStorage( ) # parse form or url data user, pswd, site = commonhtml.getstandardpopfields(form) try: if form['action'].value == 'Reply': headers = {'From': mailconfig.myaddress, 'To': getfield(form, 'From'), 'Cc': mailconfig.myaddress, 'Subject': 'Re: ' + getfield(form, 'Subject')} commonhtml.editpage('Reply', headers, quotetext(form)) elif form['action'].value == 'Forward': headers = {'From': mailconfig.myaddress, 'To': '', 'Cc': mailconfig.myaddress, 'Subject': 'Fwd: ' + getfield(form, 'Subject')} commonhtml.editpage('Forward', headers, quotetext(form)) elif form['action'].value == 'Delete': msgnum = int(form['mnum'].value) # or string.atoi, but not eval( ) commonhtml.runsilent( # mnum field is required here pymail.deletemessages, (site, user, secret.decode(pswd), [msgnum], 0) ) commonhtml.confirmationpage('Delete') else: assert 0, 'Invalid view action requested' except: commonhtml.errorpage('Cannot process view action') This script receives all information about the selected message as form input field data (some hidden, some not) along with the selected action's name. The next step in the interaction depends upon the action selected:
All these actions use data passed in from the prior page's form, but only the Delete action cares about the POP username and password and must decode the password received (it arrives here from hidden form input fields generated in the prior page's HTML). <IP_ADDRESS> Reply and forwardIf you select Reply as the next action, the message edit page in Figure 13-16 is generated by the script. Text on this page is editable, and pressing this page's Send button again triggers the send mail script we saw in Example 13-4. If all goes well, we'll receive the same confirmation page we got earlier when writing new mail from scratch (Figure 13-4). Figure 13-16. PyMailCgi reply pageForward operations are virtually the same, except for a few email header differences. All of this busy-ness comes "for free," because Reply and Forward pages are generated by calling commonhtml.editpage, the same utility used to create a new mail composition page. Here, we simply pass the utility preformatted header line strings (e.g., replies add "Re:" to the subject text). We applied the same sort of reuse trick in PyMailGui, but in a different context. In PyMailCgi, one script handles three pages; in PyMailGui, one callback function handles three buttons, but the architecture is similar. <IP_ADDRESS> DeleteSelecting the Delete action on a message view page and pressing Next will cause the onViewSubmit script to immediately delete the message being viewed. Deletions are performed by calling a reusable delete utility function coded in Chapter 11; the call to the utility is wrapped in a commonhtml.runsilent call that prevents print statements in the utility from showing up in the HTML reply stream (they are just status messages, not HTML code). Figure 13-17 shows a delete operation in action. Figure 13-17. PyMailCgi view page, delete selectedAs mentioned, Delete is the only action that uses the POP account information (user, password, and site) that was passed in from hidden fields on the prior (message view) page. By contrast, the Reply and Forward actions format an edit page, which ultimately sends a message to the SMTP server; no POP information is needed or passed. But at this point in the interaction, the POP password has racked up more than a few frequent flyer miles. In fact, it may have crossed phone lines, satellite links, and continents on its journey from machine to machine. This process is illustrated here:
Along the way, scripts have passed the password between pages as both a URL parameter and an HTML hidden input field; either way, they have always passed its encrypted string, and never passed an unencrypted password and username together in any transaction. Upon a Delete request, the password must be decoded here using the secret module before passing it to the POP server. If the script can access the POP server again and delete the selected message, another confirmation page appears, as shown in Figure 13-18. Figure 13-18. PyMailCgi delete confirmationNote that you really should click "Back to root page" after a successful deletion -- don't use your browser's Back button to return to the message selection list at this point, because the delete has changed the relative numbers of some messages in the list. PyMilGui worked around this problem by only deleting on exit, but PyMailCgi deletes mail immediately since there is no notion of "on exit." Clicking on a view link in an old selection list page may not bring up the message you think it should, if it comes after a message that was deleted. This is a property of POP email in general: incoming mail simply adds to the mail list with higher message numbers, but deletions remove mail from arbitrary locations in the list and hence change message numbers for all mail following the ones deleted. Even PyMailGui may get some message numbers wrong if mail is deleted by another program while the GUI is open (e.g., in a second PyMailGui instance). Alternatively, both mailers could delete all email off the server as soon as it is downloaded, such that deletions wouldn't impact POP identifiers (Microsoft Outlook uses this scheme, for instance), but this requires additional mechanisms for storing deleted email persistently for later access. One subtlety: for replies and forwards, the onViewSubmit mail action script builds up a > -quoted representation of the original message, with original "From:", "To:", and "Date:" header lines prepended to the mail's original text. Notice, though, that the original message's headers are fetched from the CGI form input, not by reparsing the original mail (the mail is not readily available at this point). In other words, the script gets mail header values from the form input fields of the view page. Because there is no "Date" field on the view page, the original message's date is also passed along to the action script as a hidden input field to avoid reloading the message. Try tracing through the code in this chapter's listings to see if you can follow dates from page to page. |

THERE'S SOMETHING ABOUT MARY RATING: 7 / 10 --> Good movie
The Farrelly Brothers' third film, after DUMB AND DUMBER (7.5/10) and KINGPIN (8/10), brings together the real-life couple of Cameron Diaz and Matt Dillon, some nasty humour, a cute dog, and a mix of love, fate and romance.
PLOT: High-school nerd Ted gets lucky when the cutest girl in his class asks him to the prom.  Thirteen years later, Ted still can't get Mary out of his mind, and hires a private detective (Dillon) to find her. Once found, it turns out that Mary has more than one suitor, and that's when the real fun begins.
CRITIQUE: Likeable comedy with a few extremely funny scenes, some funny looking people, and a plot that won't ever put you to sleep. Having said that, I must admit that I did like the Farrellys' two previous films more than this one, but that is saying a lot, since I really did love those earlier pics. This one is also quite funny, but it didn't really blow me away like the others. Then again, maybe my expectations were too high.
Continuing where their other pictures left off, the Farrellys' create a cutesy world of people with strange and endearing qualities, and a simple plot by which to tie them all together. This one also includes plenty of toilet humour, but also some borderline fun-making of the disabled and mentally-challenged. I must admit that I really wasn't sure whether to laugh at some points or not. Not a good place to be. Having said that, the scenes that did tear through the audience, and yours truly, were extremely hilarious, and went on for several minutes after the punchline. The laughter practically killed out the next scene for one of the best ones in the movie (something to do with hair gel).
On the negative end, I did not like the musical interludes of Jonathan Richman that ran through the entire picture. I found them quite useless, unfunny and distracting. Also, I found that a lot of the funnier scenes had already been shown in the film's trailer. And of course, I never quite buy the fact that these beautiful, intelligent, single women still can't seem to find the "right guy" (see KISS THE GIRLS (7/10). I did really like all of the actors in the film, especially Ben Stiller, who appears to be solidifying his mark as a great comical actor with this picture and one of my favourites from 1996, FLIRTING WITH DISASTER (8/10). I also liked Matt Dillon with his big teeth, and Lee Evans with his superb faux-sympathy British accent. Funny stuff. Also, make sure that you stay for the credits, because there is an entire montage of outtakes from the film that plays under a lip-synched version of "Build me up buttercup", which is really cool. Overall, a cute comedy with a decent premise, and a few particularly hilarious scenes.
Little Known Facts: The Farrellys big break came when they somehow got a copy of their script "Dust to Dust" into the hands of Eddie Murphy via Murphy's neighbour. They only found out about Murphy's interest, when they saw Eddie mention the script on the David Letterman show one night. Matt Dillon is a high school dropout. In between acting gigs, Dillon has branched out into the restaurant business. Close to home in his native New York, he co-owns both a bar called the Whiskey and a swanky uptown eatery called the Falls. Cameron Diaz stands 5"9, started working as a model at the early age of 16, and loves cats. Ben Stiller's father is Jerry Stiller. He played George Costanza's (Jason Alexander) father on TV's "Seinfeld". Peter Farrelly has written a novel entitled "Outside Providence" which is currently being filmed starring Alec Baldwin. Rob Moran, who plays the cop in this film, also played the millionaire bowler in KINGPIN, and the bartender in DUMB AND DUMBER. He is old friends with the Farrelly Brothers from College, and is currently married to Entertainment Tonight anchor/correspondant Julie Moran. Harland Williams, who plays the nutty hitchhiker in this film, also played a state trooper in the Farrelly's earlier DUMB AND DUMBER, and was the star of the unfortunate ROCKET MAN.

My undergraduate thesis project. Born geometry is a geometric structure which can be placed on a 2n dimensional manifold which endows the manifold with certain symmetries of interest to theoretical physicists. The Born structure is composed of a para-hypercomplex structure along with some integrability conditions for the eigenbundles which come along with the para-hypercomplex structure. A particular connection on the tangent bundle reduces to the Levi-Civita connection on phase spaceplus a torsion term. A connection on phase space with nonzero torsion causes an effect called relative locality, which modifies the Heisenberg Uncertainty relation. I derive the Born connection on a few complex manifolds, and find that Hopf manifolds possess a Born connection with nonzero curvature. Link.
Manuscript in progress. This project is about controlling cargo in microfluids. Microfluidic chips are important for constructing micro and nanomachines (through synthetic biology or otherwise). We tried to characterize the controllability of particles by various actuators, such as spherical beads suspended in the fluid which can be controlled using magnets. Similar work in this area has been done here (arxiv link).

Read clipping based on quality, position or sequence matching
This tool provides simple, powerful read clipping capabilities that allow you to remove low quality strings of bases, sections of reads, and reads containing user-provided sequences.
There are three options for clipping (quality, position and sequence), which can be used alone or in combination. In addition, you can also specify a clipping representation, which determines exactly how ClipReads applies clips to the reads (soft clips, writing Q0 base quality scores, etc.). Please note that you MUST specify at least one of the three clipping options, and specifying a clipping representation is not sufficient. If you do not specify a clipping option, the program will run but it will not do anything to your reads.
argmax_x{ \sum{i = x + 1}^l (qTrimmingThreshold - qual)to the end of the read. This is copied from BWA. Walk through the read from the end (in machine cycle order) to the beginning, calculating the running sum of qTrimmingThreshold - qual. While we do this, we track the maximum value of this sum where the delta > 0. After the loop, clipPoint is either -1 (don't do anything) or the clipping index in the read (from the end).
Any number of BAM files.
A new BAM file containing all of the reads from the input BAMs with the user-specified clipping operation applied to each read.
Number of examined reads 13 Number of clipped reads 13 Percent of clipped reads 100.00 Number of examined bases 988 Number of clipped bases 126 Percent of clipped bases 12.75 Number of quality-score clipped bases 126 Number of range clipped bases 0 Number of sequence clipped bases 0
java -jar GenomeAnalysisTK.jar \ -T ClipReads \ -R reference.fasta \ -I original.bam \ -o clipped.bam \ -XF seqsToClip.fasta \ -X CCCCC \ -CT "1-5,11-15" \ -QT 10
The command line shown above will apply all three options in combination. See the detailed examples below to see how the choice of clipping representation affects the output.
Suppose we are given this read:
314KGAAXX090507:1:19:1420:1123#0 16 chrM 3116 29 76M * * * TAGGACCCGGGCCCCCCTCCCCAATCCTCCAACGCATATAGCGGCCGCGCCTTCCCCCGTAAATGATATCATCTCA #################4?6/?2135;;;'1/=/<'B9;12;68?A79@,@==@9?=AAA3;A@B;A?B54;?ABA
If we are clipping reads with -QT 10 and -CR WRITE_NS, we get:
314KGAAXX090507:1:19:1420:1123#0 16 chrM 3116 29 76M * * * NNNNNNNNNNNNNNNNNTCCCCAATCCTCCAACGCATATAGCGGCCGCGCCTTCCCCCGTAAATGATATCATCTCA #################4?6/?2135;;;'1/=/<'B9;12;68?A79@,@==@9?=AAA3;A@B;A?B54;?ABA
Whereas with -QT 10 -CR WRITE_Q0S:
314KGAAXX090507:1:19:1420:1123#0 16 chrM 3116 29 76M * * * TAGGACCCGGGCCCCCCTCCCCAATCCTCCAACGCATATAGCGGCCGCGCCTTCCCCCGTAAATGATATCATCTCA !!!!!!!!!!!!!!!!!4?6/?2135;;;'1/=/<'B9;12;68?A79@,@==@9?=AAA3;A@B;A?B54;?ABA
Or -QT 10 -CR SOFTCLIP_BASES:
314KGAAXX090507:1:19:1420:1123#0 16 chrM 3133 29 17S59M * * * TAGGACCCGGGCCCCCCTCCCCAATCCTCCAACGCATATAGCGGCCGCGCCTTCCCCCGTAAATGATATCATCTCA #################4?6/?2135;;;'1/=/<'B9;12;68?A79@,@==@9?=AAA3;A@B;A?B54;?ABA
These Read Filters are automatically applied to the data by the Engine before processing by ClipReads.
This tool does not apply any downsampling by default.
All tools inherit arguments from the GATK Engine' "CommandLineGATK" argument collection, which can be used to modify various aspects of the tool's function. For example, the -L argument directs the GATK engine to restrict processing to specific genomic intervals; or the -rf argument allows you to apply certain read filters to exclude some of the data from the analysis.
This table summarizes the command-line arguments that are specific to this tool. For more details on each argument, see the list further down below the table or click on an argument name to jump directly to that entry in the list.
| Argument name(s) | Default value | Summary | |
|---|---|---|---|
| Optional Outputs | |||
| --out -o |
NA | Write BAM output here | |
| --outputStatistics -os |
NA | File to output statistics | |
| Optional Parameters | |||
| --clipRepresentation -CR |
NA | How should we actually clip the bases? | |
| --clipSequence -X |
NA | Remove sequences within reads matching this sequence | |
| --clipSequencesFile -XF |
NA | Remove sequences within reads matching the sequences in this FASTA file | |
| --cyclesToTrim -CT |
NA | String indicating machine cycles to clip from the reads | |
| --qTrimmingThreshold -QT |
-1 | If provided, the Q-score clipper will be applied |
Arguments in this list are specific to this tool. Keep in mind that other arguments are available that are shared with other tools (e.g. command-line GATK arguments); see Inherited arguments above.
How should we actually clip the bases?
The different values for this argument determines how ClipReads applies clips to the reads. This can range
from writing Ns over the clipped bases to hard clipping away the bases from the BAM.
The --clipRepresentation argument is an enumerated type (ClippingRepresentation), which can have one of the following values:
ClippingRepresentation
Remove sequences within reads matching this sequence
Clips bases from the reads matching the provided SEQ. Can be provided any number of times on the command line
String[]
Remove sequences within reads matching the sequences in this FASTA file
Reads the sequences in the provided FASTA file, and clip any bases that exactly match any of the
sequences in the file.
String
String indicating machine cycles to clip from the reads
Clips machine cycles from the read. Accepts a string of ranges of the form start1-end1,start2-end2, etc.
For each start/end pair, removes bases in machine cycles from start to end, inclusive. These are 1-based
values (positions). For example, 1-5,10-12 clips the first 5 bases, and then three bases at cycles 10, 11,
and 12.
String
Write BAM output here
The output SAM/BAM file will be written here
GATKSAMFileWriter
File to output statistics
If provided, ClipReads will write summary statistics about the clipping operations applied to the reads in this file.
PrintStream
If provided, the Q-score clipper will be applied
If a value > 0 is provided, then the quality score based read clipper will be applied to the reads using this
quality score threshold.

A primary symptom of many infectious diseases is fever.
This has lead to monitoring the temperature of pedestrians
in hospitals, airports, corporate building companies, schools,
and other public areas. Thermos screen provides a non-invasive,
non-contact method of screening large groups of people for
elevated facial skin temperature quickly and easily.
Potentially febrile individuals can be detected with minimal
inconvenience and disruption to pedestrian flow.
Temperature detection thermal camera is best utilized as the first of a two-point
fever detection process.
At the entrance to crowded areas, temperature detection thermal
camera is used to detect individuals whose facial skin temperature is higher than normal.
Fever is then confirmed using a medical thermometer. This two-point system enables
large groups of people to be screened quickly and accurately to effectively prevent
febrile individuals from entering areas where contagious diseases can spread easily.
Any object with a temperature will emit infrared rays. The thermal imager 100 receives the infrared rays emitted by the object, displays the temperature distribution on the surface of the measured object through a colored picture, and finds the abnormal point of the temperature according to the small difference in temperature degree, thus Play the role of asking and maintaining. It is also commonly referred to as an infrared camera.
And the working principle of temperature detection thermal camera is to answer thermal infrared imaging technology. At its core is the thermal imager, which is a sensor that can detect very small temperature differences and convert the temperature difference into a real-time video image for display. However, they can only see the hot corridors of people and objects, and cannot see the true face of objects.
Compared with the traditional thermometer and the frontal thermometer, the thermal imaging infrared camera can achieve a longer distance (a few meters) in the case of non-contact multi-target temperature detection at the same time. It can avoid the retention caused by mass temperature testing. It reduces human contact, is good for reducing disease risk, is relatively safe and convenient, and is a way to identify people with fever in public places.

If you don't know what neural processes are, this blog post is a great place to start. This concept which builds on the ideas of deep learning and gaussian processes was recently explored by DeepMind in their ICML 2018 workshop publication. The idea is quite audacious I thought as it models each weight in a network as a Gaussian distribution. This gives you virtually an infinite number of deep networks; only a few datapoints should suffice to sample one specific network that will be well-suited for these datapoints (i.e. for the task at hand).
This article was quite discussed this week as it has been covered by some mainstream technology media. A group of 3 from fast.ai (Andrew Shaw, Yaroslav Bulatov and Jeremy Howard) managed to train a ResNet 50 on ImagetNet from scratch and to reach 93+% top-5 accuracy in 18 minutes for about $40. This article explains their approach. I wish we had a bit more details on the results; in particular an ablation study of the different tricks they used (using rectangular images, proressive resizing, dynamic batch sizes...).
More and more work is dedicated to applying the tools of deep learning on computer vision to graph structures. As this blog post explains clearly, this problem is far from being trivial. The paper related in the blog post, titled Graph Attention Networks was published at ICLR this year and offers a clever solution. In this blog post, authors summarise the proposed solution and point to other works which extend their idea.
This blog post is an extended litterature review on the topic of model scheduling which is here described as anything that has to do with modifying hyper-parameters of a model during training. The covered themes range from dropout to architecture growth, not to mention pruning and teacher/student techniques.
This is the second part of a collection of blog posts targeted towards adversarial training and robustness of classifiers againt adversarial perturbations; the first part can be found here. The explanations are clear and I liked that the authors presented the results of their experiments while giving an overview of the topic of robustness. We learn about the min-max formulation of this problem, Danskin's theorem and how to apply it (using Projected Gradient Descent) and how former methods such as Fast Gradient Sign Method (FGSM) were seemingly not following the theorem.
This is not a recent post but it has been directly sent to me; and the amount of work is impressive. This can be basically seen as a webpage summarizing the entirety of the 2017th edition of the Reinforcement Learning Summer School by the CIFAR Institute. The writing style is a bit on the note-taking side than on the explantion side but considering Mr. Kurin also provides the links to the slides and videos of each presentation he covers, I think this page could serves as a wonderful helping material if you decide to go through the presentations yourself.
Nothing technical in this blog post; however the author who is a regular DOTA 2 player explains in details and with examples why the 3 games played by OpenAI last week were so surprising. He analyses the apparent behavior of the bot players and makes it simple to understand for those who are not familiar with the game!
In reinforcement learning, most of the reward functions are tailored for the task at hand. For instance, in the car pole balancing problem, the reward value is traditionally based on the angle of the pole to the vertical (if it's too high, the reward could be negative for instance). Designing a reward function for each problem is not scalable and time consuming. On the contrary, this work explores reward functions which are not based on the problem at hand. Rather, in intuitive terms, authors try to model curiosity and encourage the network not to be bored!
This is a rather high-level introduction of the paper Universal Language Model Fine-tuning for Text Classification by Howard & Ruder in which they present a transfer learning method specifically for NLP. The claims are quite impressive as they report same performance when fine-tuning with 100 samples than when training from scratch with 10,000 samples. The author of the blog post also provides notebooks of experiments he did on his own to test this method on the Amazon Reviews dataset.
27 terabytes worth of datasets, papers and courses shared via the torrent protocol. You will find classic material (Andrew Ng's Coursera course, ImagetNet, MNIST) and some more exotic (Labeled Fishes in the Wild, Movies Fight Detection Dataset,...)
A collection of all the interactive ML demos you can find online. Well, maybe not all of them, but a fair number. And the project is open-source so anyone is invited to contribute to the list.


Class Methods or Nah?
May 14, 2015
For this blog, I'm gonna be piggybacking off of the Ticket example from Chapter 3 of The Well Grounded Rubyist, because well, of all the resources I've gone through it provided the best example in my opinion. One quick thing to keep in mind: "objects are instances of classes."
Let's say we have a class, Credit_Cards. If we wanted to, we could create a new Credit_Cards object to create say, a Visa credit card. Any method defined within our Credit_Cards class using the convention 'def methodname' is an instance method, meaning we can pass it as a message to our new Visa card object since it's an instance of the class Credit_Cards. In short, a Class instance method works for an instance of a Class. An example of how to create a class method and how to call it can be seen in the figure below. Note that there are other ways for creating and calling class methods though.
Class methods on the otherhand are inaccessible by class instances though (supposedly you can if you explicitly reference them, but let's not worry about that for now). Class methods work by being passed as messages to the actual Class in which they're defined (remember, classes are objects, too), rather than to an instance of the class. The question of when to use a class method may be a tricky one to answer, but one "simple" answer may arise after answering the question, "Is this operation that a single instance should be able to do?"
The last question may not make much sense, so let's consider the Class.new method. Class.new is a class method because well, it wouldn't make sense to have it as an instance method. If it were, then an instance of a class would basically be able to instantiate another instance of the same class and so forth. So in terms of our credit card example, a credit card would be able to "create" another credit card. That might be cool, but it wouldn't be if you ended up racking more debt. Not desirable. And just imagine if instead of credit cards, we were using a Dollar_Bills class. Each dollar would be able to generate another dollar... Well that may not be so bad, but it's probably illegal. Anyways, the point is, there's things that instances should be able to do and shouldn't be able to do.
Something that our Visa credit card most likely wouldn't be able to do is tell you which of your credit cards have the highest credit limit. Why? Because it only knows about itself in this case, being its own instance. You can probably have a method that prints a specific card's credit limit, but if we really wanted to see which of your current cards had the highest limit, it would make more sense to not look at 1 specific card and look at things in a collective way.
Having a class method instead, like "highest_limit" to find the card with the highest credit would be best suited for our example where running "Credit_cards.new()" creates a single credit card. It is worth noting however, that a class method may not be necessary if we were to have instead passed in an array of cards in say, a Card_Comparer class that had an instance method to run operations for us.
And like instance methods, class methods can take in a number of arguments as you can see from the example above. So again, when it comes down to whether or not to use them, it may really just come down to a matter of "Should a single instance be able to do this or nah?"

Connected Songs Tutorial
Sometimes you may want to create several songs that are connected to each other in different ways.
For example, a game can have music in different contexts such as main/pause menu, calm gameplay, intense gameplay, combat, boss fight, success and failure. If you want these songs to feel as they were part of a larger musical "package", you might want to create musical connections between these different contexts.
This tutorial explores the different ways that Abundant Music can support such connections between songs.
Ideas
Reusing seed presets for motifs, rythms, instruments, song structure etc.
Just a simple switch between major and minor while increasing/decreasing tempo can be very effective.
Switching to more intense or strong instruments while increasing overall render amount.
Unique levels with different instruments and motifs but same structure overall.


Lyon's ex-All Black Ngatai wary of 'massive' Leinster test
Paris - Lyon's former New Zealand centre Charlie Ngatai says hosting record four-time winners Leinster in the Champions Cup on Sunday will be "massive" for the inexperienced club at the highest level of European rugby.
The French outfit, who lead the Top 14, are only in the competition for the second time and lost all six of their pool matches last season.
"It's going to be massive. They're going to want to come down here and give it their best," Ngatai told AFP.
"I guess we have a chance to put a foot forward to show how we can hold our own against a big team.
"We had a taste of it last year, we know what the standards are and we have to lift our standards each game."
The 25-14 defeat to Northampton last weekend was their second defeat in three games after having remained unbeaten for the opening seven rounds of the domestic campaign.
"It wasn't where our standards have been this season. We were disappointed in our own performance. At this level you can't give away as many penalties," Ngatai said.
Lining up outside the one-time All Black Ngatai could be Fiji winger Josua Tuisova who joined 'The Wolves' from Toulon for the new campaign.
The 2016 seven-a-side Olympic champion is an injury doubt due to an ankle problem but has scored once in two games following his arrival at the Matmut Stadium after being knocked out of the Rugby World Cup pool stages.
"He can turn nothing into something. You just give him the ball and he feeds off that. You can see his raw power and his ability to break the line," Ngatai said.
"The more ball we can give him, the more dangerous it is for the opposition to try and defend him. He pulls in two or three defenders which they have to worry about. He opens up more space for us," he added.
Elsewhere this weekend, title holder Saracens welcome the Ospreys in their first home fixture since they were handed a £5 million fine and docked 35 points for breaching Premiership Rugby's salary cap rules.
On Sunday, South Africa's World Cup winning flyhalf Handre Pollard could make his Montpellier debut as they play Gloucester after he replaced the departed Aaron Cruden in the French club's squad for the competition.

Communication glitches happen all the time.
Assumptions stay in our heads instead of being expressed directly.
To design a good software, it's important to know what that software is about.
Mainly, domain driven design focuses on:
There are 3 main layers you should know while developing your application:


INTEX Winter 2021
The BYU ancient scripture department has sent a team of researchers to Egypt to excavate mummies from an ancient burial ground called Fag el-Gamous. Their data collection and storage methods for information from the excavations were inconsistent and inefficient and they had no easy way to share their findings with peers or with the public. For this reason, our end of semester project for the BYU IS core was to design a website to store the data they had already collected and standardize and streamline the data collection process for the future. We applied concepts we had learned throughout the semester by using ASP.NET MVC Core with C# for the website and hosting it through AWS Elastic Beanstalk and RDS. We also applied concepts of security and controls by incorporating aspects of authentication and authorization to access certain capabilities on the website.
INTEX Fall 2020
This was the culminating project for the first semester of the BYU IS program. The challenge was to design a recruiting website that helps black job seekers overcome roadblocks that put them at a disadvantage in the recruiting process. Our solution incorporated elements of Python programming, SQL, Django web framework, a live PostgreSQL database, and a recommendation model. We then developed a prototype website and presented our propoal to the "potential employer."
To start off the first semester of the BYU IS program, we worked on a week long business case with Ernst and Young. The case was to work with an imaginary company, VoydSec, to assess and strengthen their internal security posture. The deliverable was a report identifying key issues and risks in a previously performed penetration test, identifying key issues and risks in the change management process, analyzing login attempts during the time frame of a suspected security breach, and providing recommendations on how to mitigate all the risks identified. Below is a link to the full report and a Tableau Story showing the risks identified in the login attempt analysis.
This was a simple project at the beginning of my business programming class where we used HTML and JavaScript to create a game similar to Hangman with 80's era songs. Make sure to give it a go!
Global Superstore Analysis Using Tableau
The above visualizations were created to analyze the Global Superstore data in regards to their profitability in the United States. In the top left, it shows that California's profit has been following an upward trend for the last two years. In the top right, it shows that while they are losing money in several states, California and New York are the two most profitable states for Global Superstore. In the bottom left, it shows that Office Supplies is clearly the most profitable product category in California while furniture seems to not be very lucrative. In the bottom right, it shows that based on previous growth trends, Global Superstore can expect steadily increasing revenue in California over the next year of business.


Just a quick post that may be useful to those who code in c++. It is one of those not very obvious features of c++ which comes up when you start optimizing the code for efficiency. This, in fact, was brought up by one of my senior colleagues because he is currently doing the optimization work.
What I wanted to share is this: the ordering in which you place member variables in the class matters. In the picture above are, at first sight, very similar dummy classes. Both have four member variables: 2 integers and 2 booleans. The only difference is the variable declaration order. Class A nicely separates integers from booleans. Class B, on the other hand, mixes up the variable types. This is a classical case when you have an existing class and a programmer just adds up the variables at the end of the class as he introduces new features.
The problem is that the ordering of the variable types affects the way the compiler allocates memory. If we consider provided examples, one instance of class-A costs 12 bytes as the compiler tries to lump consequent boolean variables into 4 bytes. As a matter of fact, you can add two more booleans and not increase the allocated memory. The instance of class-B, however, would cost 16 bytes. I bet you already understand why. The compiler fails to group the booleans since they are not consequent. If you are using GCC, chances are you can save some memory using this trick. For this simple case we got 25% memory allocation reduction just from reordering! Not bad, isn't it? So if you work with c++ codebase, go ahead and check this right now! :)

Dear Mr Key : Glancing at the section entitled Make Your Own Glue (23rd February), I misread the third of your cut-out-and-keep labels as “Nameless God”. I very much like the idea of keeping a little tin marked “Nameless God” on a shelf, possibly in the kitchen, and wonder if you could provide a label accordingly. Furthermore, I wonder if Hooting Yard readers can make suggestions as to what I could actually keep in the tin? I am not particularly religious, but this has set me to thinking that it would be a good way to nurture my spirituality. Any ideas? Yours sincerely, Tim Thurn

0m Insufflated 30 mg of powdered 2CB.  It's almost too intense. Got an amazing body buzz and have a hard time standing and talking. There's neon yellow, pink, orange, green, and blues all over. Patterns are moving and it looks like I'm inside a colored crystal or kaleidescope. The guys seemed to get really hot, but me and the other girl seemed to be cold. Then I got comfortable.
30m I settle into a comfortable trip. I still have intense visuals and a body buzz, but I can now think and talk. I didn't lose my appetite on this or get nauseous like acid or ecstasy. I feel very erotic and amazing. The colors are so pretty. They are like nothing I've seen. Very neon. My friend was playing xbox and it looked like clay. It was snowing outside and looked so beautiful. There are tracers as well. We called them issers because a person would leave the room but you'd still see them there. They were very long tracers.
4hr I start to taper down a bit. Still lots of visuals, but not as intense. I insufflate another 30mg and start tripping intensely again. My boyfriend and I went into the complete dark and we were kissing. It felt so amazing. All I could see was just a neon explosion of colors whether my eyes were open or not. The body buzz makes sex amazing. The kaleidescope of colors is so bright and intense that I can see the basic gist of what's around me, but it's really hard to pay attention to details, like lighting a cigarette. I could see the air, feel the music. Sometimes when I talked I could hear echoing in my head.
8hr We decide to go for broke and insufflate another 30 mg. It seems the people that ate it didn't trip as hard. It hurt like hell, but it's better to take it straight to the head. We're rocking out to tool and dancing. We decide to go for a walk up town to buy cigarettes. We went into the Casey's gas station and the tiled floor was just swimming with colors. We walked back and watched the trees dance and move. We go back inside and watch my friend play guitar. He looks like he has 100 fingers.
12 hr We trip hard for another 4 hours. I'm still seeing amazing colors, but I have to go home. It's about 4 am. I'm driving in the snow and it looks insane. (I wouldn't recommend driving on drugs or alcohol.)
[Erowid Note: Driving while intoxicated or tripping is dangerous and irresponsible because it endangers other people. Don't do it!] I went home and layed in bed eating cheerios. I try to close my eyes but I see bright neon colors for another couple hours.
14 hr I finally fall asleep.
The next day I didn't wake up to any sort of hangover feeling or any other side effects. I slept pretty well What's so amazing about this drug is if I bump up I start at a peak trip again. It feels so amazing and I've never seen colors like this. I would do it 100 more times.
