This website scans Reddit posts on WallStreetBets to track how many times stock tickers are mentioned and the sentiment of the post. The website is currently set to collect the newest posts every 15 minutes.
All frequency is measured by percentage of posts that mention the stock out of all new posts, and is plotted logarithmically. A python library called nltk is used to determine the sentiment of posts that mention a stock, and gives a number between 1 and -1, with one being very positive and -1 being very negative. Neutral sentiment (values between 0.3 and -0.3) are ignored.
Graphs are updated every 3 hours New Zealand time. All times are currently displayed in New Zealand time.
Some text displayed may be mistaken for stock tickers. Be aware that bots are included in the data.

I first heard about MDPV back in about 2007, and it sounded interesting as its effect were commonly compared to methylphenidate, and I had found that stuff helpful but it elevated my alert level and anxiety too much, leading to two incidents of psychotic behaviour in which the police were called, while I was living in new zealand.
MDPV, however, lacks this psychosis induction effect for me. It also has a diminished 'fixation' effect as compared to methamphetamine. I also find that it has an after effect which actually reduces social anxiety for up to 3 weeks after a moderate 18 hour binge, probably an effect that would build up with daily dosing.
It somewhat elevates my excitement level, but not so much as caffeine, which I find at times when I'm embedded within an fps game or listening to music with earphones I discover my natural level of expression voice/body language etc is a bit intense. So not as bad as if I'd just dosed 200-300mg of caffeine.
I made the title better than meth because for me it is better. It doesn't cause the biggest problems I have with it, obsessive fixation and rigidity to near the same degree, I am able to pull myself out of a mental sinkhole much easier, and shift my attention. In fact on high doses of meth I actually get what seems to be some kind of tunnel vision where peripheral stimuli don't get any attention to the point of the ridiculous, like, probably a bomb could go off next to me on a high dose of meth when I'm fixating on something and I'd not even notice let alone jump in surprise.
My only gripe with MDPV is - well I wish it lasted 8 hours, but in my experience drugs either last 3-4 hours at effective levels or 12 hours, but at the latter the insomnia persists another 6-12 hours which is not acceptable, and I'm sure it's wrecking my body's recovery during sleep when I get it in that state - ok the only big gripe I have is it suppresses my thirst and hunger better than any drug I've ever taken ever, and unfortunately I already have a mild degree of anorexic tendencies. With awareness and routine feeding I'm sure I could get around that. It doesn't inhibit my digestion so much as inhibit my desire.

Provides several helper functions for working with 'knitr' and 'LaTeX'. It includes 'xTab' for creating traditional 'LaTeX' tables, 'lTab' for generating 'longtable' environments, and 'sTab' for generating a 'supertabular' environment. Additionally, this package contains a knitr_setup() function which fixes a well-known bug in 'knitr', which distorts the 'results="asis"' command when used in conjunction with user-defined commands; and a com command (<<com=TRUE>>=) which renders the output from 'knitr' as a 'LaTeX' command.

Helping a captive big cat return to the wild is about more than helping them become accustomed to hunting, said Kathleen Alexander, a professor Virginia Tech who has worked with captive carnivores. Hunting, she says, is highly instinctual behavior in animals such as lions and tigers that doesn’t need to be taught. She compared it to the reaction that a domestic cat would have to seeing a string being dangled across the room.

Snoward Bound Read More
They are insulated by thick hair, and their wide, fur-covered feet act as natural snowshoes. Snow leopards have powerful legs and are tremendous leapers, able to jump as far as 50 feet. They use their long tails for balance and as blankets to cover sensitive body parts against the severe mountain chill. These majestic creatures are a popular subject of nature photographers.

Indian Beauty Read More
There were eight tiger subspecies at one time, but three became extinct during the 20th century. Over the last 100 years, hunting and forest destruction have reduced tiger populations from hundreds of thousands of animals to perhaps fewer than 2,500. Tigers are hunted as trophies, and also for body parts that are used in traditional Chinese medicine. All five remaining tiger subspecies are at-risk, and many protection programs are in place.

What the trac?
trac is an open-source collaboration software that combines a Wiki, file versioning and a ticketing system. If you're not using it (yet), this page is not for you (yet). tracregate is a client for any (even multiple) trac installation that aims to provide a modern, slick interface to trac's ticket system.
Why should I be using tickets?
Don't think of a ticket so much as a task, think of it as a workflow. If you want to start a workflow (that may involve a number of tasks), you open a ticket. From there, everything can happen - responsibilities change, things may have to be postponed, the workflow develops a life of it's own. The ticket helps you to keep track of what's happening.

Wealth.ng offers individuals investment opportunities on NSE
by NM PartnersWealth.ng is the investment platform which enables any individual invest in securities such as, Fixed Income, Agriculture, and a selection of Stocks on the Nigerian Stock market.
Wealth.ng via their eponymous website has onboarded a lot of investors old & new to engage in investments from the comfort of their homes which is now a huge trend currently.
Recently, they took the convenience of their service a step further as they have now released their investment app first for Android and then for iOS, which users can sign up and invest with, in addition to a user experience upgrade of the platform on the web.
The service has garnered praise and acclaim for both the web and mobile apps as seen on social media and in app store reviews
According to one of the numerous reviews, “navigation has been swifter than when using web browser. I’ve been anticipating this app for a long time and I’m glad that its out.”
And another comments “This is great, and I love the development and I will be expecting more from you like foreign stock and others.”
Some of the things we like about Wealth.ng include:
- Access to your Networth and Cash Balance which can also be viewed in US Dollars.
- The lightweight apps and their ease of use.
- Interest rates for Fixed Income are straightforward (as opposed subtracting discount rates like in traditional methods)
- Choice of Payment options: You can pay directly from your Debit Card or Bank Account, and even via a transfer for large value transactions.
- In “My Portfolio”, you can see exactly when your fixed-income investment will mature and payout to you
- Transaction list that displays a searchable list of all the investment transactions that you have done on the platform.
- Minimum transaction value is relatively low making it easy to get in with small amounts.
- The different asset classes and securities listed in the marketplace looks like a solid selection.
Signing up for Wealth.ng is as easy as opening a Facebook account. Either on the web or via their mobile apps, any individual can become an investor in the likes of Zenith Bank, Dangote Cement, MTN, Okomu Oil, Nestle, etc. within just ten minutes.

--- layout: archive title: Zulip Chat Archive permalink: /stream/113488-general/topic/fin.20as.20a.20subtype.html ---
Now that we are changing core, what do people think of redefining fin n
as {k // k < n}
?
Why?
Because it's a bit weird to me that this type would get special treating.
It's a subtype, but it isn't defined as such.
So the whole subtype machinery has to be reproven for fin
.
For instance?
Well, there are things like fin.eq_of_veq
that are just copies of analogous subtype
theorems
Right but how big is the duplication?
Not that large but it has an effect on all later work. You have to use different functions and different theorems, something like the situation with nat.cast
vs int.of_nat
I think it doesn't add anything to write it as a structure like that. It might make sense to have a separate definition if fin
was defined using the fancy inductive family construction, but right now it's literally just a subset
If someone feels like creating a branch of Lean with this change to see how much mathlib gets simplified, I'd be curious to see
I don't think there will be any simplification, just changing constant names in a few places. It's just more regular
To me, it feels a bit like the difference between writing a structure with two fields vs using prod
. Sometimes, the structure is a nicer solution
it's not like the names of the fields are especially meaningful here
the defeq to subtype seems useful
What about using coercions from and to subtypes?
cycles, can't do it
lean 3 coercions kind of suck
I mean functions to convert
The sorts of places where you want the defeq is for higher order objects like a proof that a subtype is encodable implies that fin is encodable
here you need the function to be an equiv and everything has to be transported along it
missing defeqs at the type level are difficult to patch around
I don't think there will be any simplification, just changing constant names in a few places. It's just more regular
That sounds like a lot of hassle for very little payoff
BTW, is there any difference between fin.ext_iff
and fin.eq_iff_veq
?
I prefer to think of changes in terms of how close to ideal they are, rather than how close to today's version they are. The latter mentality leads to cruft
@Yury G. Kudryashov Apparently not, and they are literally neighbors in the file. Someone must have missed the first one and wrote the second
...on the same day by the same person (ext_iff
, eq_iff_veq
)
In two different commits.
This is actually another place where we could stand to be more regular in our naming. ext_iff
is used for a bunch of structures now, so the names of extensionality for fin
and subtype
are now odd men out

| In this game, each player begins with a score of 0. The computer will generate two random numbers between 2 and 11 for the player (the player’s cards) and two for the computer (the dealer’s cards). An ace has the value of 11; therefore there is no 1. Face cards (Jack, Queen, King) all have the value of 10. | |||

To allow users to resize the text (in the browser menu), many developers use em instead of pixels. The em size unit is recommended by the W3C. 1em is equal to the current font size. The default text size in browsers is 16px. So, the default size of 1em is 16px. The size can be calculated from pixels to em using this formula: pixels/16=em In example below,the text size in em is the same as the previous example in pixels. However, with the em size, it is possible to adjust the text size in all browsers. Unfortunately, there is still a problem with older versions of IE. The text becomes larger than it should when made larger, and smaller than it should when made smaller.

Match Play. 0-0 to 5. Should Red double? If doubled, should White take?
pips Red=137 White=138
(CorrectAnswer= 0/0, ErrorScore= 0)
A standard middle game double and take. If Red rolls a five his winning and gammon chances are very good but thing can very easily go wrong. The race is even and even if Red covers his 2-pt he has work to do. Meanwhile any entering ace for White gives him realistic winnings chances.
White wins 36% of the time while Red wins a gammon 29% of the time. As noted above, a classic double in a volatile position, easy take

Oprah Winfrey
Winfrey was born into poverty in rural Mississippi to a teenage single mother and later raised in inner-city Milwaukee. She has stated that she was molested during her childhood and early teens and became pregnant at 14; her son was born prematurely and died in infancy. Winfrey was then sent to live with the man she calls her father, Vernon Winfrey, a barber in Tennessee, and landed a job in radio while still in high school. By 19, she was a co-anchor for the local evening news. Winfrey's often emotional, extemporaneous delivery eventually led to her transfer to the daytime talk show arena, and after boosting a third-rated local Chicago talk show to first place, she launched her own production company and became internationally syndicated.


The future tense Any verb can be used in the future tense by adding the verb "to go" (poa) after the infinitive (to form) of the verb. Examples: Batman kaaNaan poa.

You can reserve facilities for your own events. The cost to rent per hour is $75. You may reserve multiple facilities and for multiple hours.


In this project, I developed a web application which can help users to search for movies, look up top rated movies, movies now playing, and help user to remember those movies he/she likes. Also, user can like other users and view their favorite movies.
The technology I used is MEAN stack, hosted on the OpenShift cloud, and the movie data fetched through the TMDb API.
To quick start using this app, use Home and Search freely without login. Use predefined credentials like the table below to test the full funtion of the app.
| Username | Password |
|---|---|
| alice | alice |
| bob | bob |
| chris | chris |
| dan | dan |
| ... | ... |
There is another special admin user, use the admin
as the username
and password
to log in as and administrator and then you can see all the users and their information.
Anyone can use the Home page without login. Users can see movies organised in Top Rated or Now Playing groups. The Top Rated movies are movies top rated calculated by the TMDb website. The Now Playing movies are movies now playing in the cinema.
Click on the Top Rated or Now Playing button to see these two different groups of movies. The movies are displayed in grids view with their thumbnail posters and scores. The Add button is for adding the movie to user's favorite, as you will imagine, only loggedin user can use this function.
Similar to home page, users don't have to log in to user the search funciton. To search for a particular movie, type full or partial movie name in the search bar, click Search button, then all the related results will display below. The results are shown will thumbnail posters, movie titles, ratings and year of release. There is a Filter input area next to the search bar, use this to filter the results by keywords.
In each result row, at the rightmost there is a blue star button, a logged in user can use this button to add the movie to their favorite movies. However, guests can not use this function.
There are two kind of users, Normal user and Admin user. A Normal user is expected to use by normal users who want to use the app, while a admin Admin is for administrative/debugging use by the author or Prof/TAs, where we view all users along with their information.
Below is a table for some of the predefined Normal user credentials for using.
| Username | Password |
|---|---|
| alice | alice |
| bob | bob |
| chris | chris |
| dan | dan |
| ... | ... |
If you want to use the Admin user, then use the admin as the username and password to login.
Register a user is easy. Click the register link on the top right of navigation bar, enter the username and passwords(twice) to register a new user. The page will notify you if your username is too short or too long, or your two passwords don't match. If you register for a username which has already existed, you will not be able to successfully register.
The Profile Page can only be used by user who has logged in. In the page, there are mainly
three sections.
1) Section for displaying the user's favorite movies.
2) Section for displaying the user's liked users.
3) Section for displaying the other user's liked movies.
The two blue toggle button at the top of the first two sections are to toggle the displays. And the number in paranthesis shows the count of favorite movies/users.
Below the Toggle Favorite Movies button is the first section, which shows the current logged in user's favorite movies. In the displaying table, you will see the name, year, thumbnail of the movies, and when you click the Movie Details button you will be navigated to the Movie Details page where you can see more details of the movie. The red Delete will remove the particular movie from the favorite movie list.
Below the Toggle People I Liked button, an area will be displaying all the users the current logged in user has liked.

The 6th Day (2000) Review by Steve Kong The Hard Boiled Movie Guide http://boiledmovies.sbay.com/
Let me first say that The 6th Day is better than Arnie's last film End of Days. But, that's not saying too much since End of Days was so terrible. We are entering in to the era of neo-Arnie a softer and gentler Arnie who makes movies that are no longer rated R, but are rated PG-13. The 6th Day has one huge failing and is rescued by one great idea. More on this later.
In The 6th Day we follow the life of ordinary guy Adam Gibson (Arnold Schwarzenegger). He's a helicopter pilot with a pretty ordinary life with a wife, daughter, and even a cute dog. On his birthday he decides to switch off a job with his work partner Hank.  Well, in any other movie a mind-over-anger approach would have taken place. But, come on! This is an Arnie film and all hell breaks loose, as there are two Arnies on screen.
In the near future and we're told the not so far away future by the opening titles cloning of pets has been perfected and though humans have been cloned, it is outlawed. The master-cloning doctor is a brilliant man named Dr. Weir (Robert Duvall) and he has a scheming business partner named Drucker (Tony Goldwyn). Well, like in real life, laws are made to be broken and Adam has been cloned and now that there are two of them in the world, one of them has to be eliminated to eliminate the evidence of illegal cloning.
The story for The 6th Day is not deep, this is an action film, but the issues brought up in the film are great! The cloning process basically reproduces an exact clone of a person within two hours. What does this mean really? It means that a person can live forever. A snapshot of a person's mind at a moment of time (called a "syncording") and a sample of the person's DNA is all that is needed to create a perfect clone. This clone doesn't even know that he is a clone. The issue of cloning is quite real in today's world and the film does bring up some of these interesting issues. It is because of this that the film survives, it is able to infuse enough action to please the audience and also put in something for the audience to think about after the film.
Where the film fails, but not failing hard enough for me to not like the film, is in its tone and setting. See, the opening titles try to scare us by saying that what we are going to see is the near future. But, it goes on specifically to let us know that this is not too far away from now. And if the film had stuck to this then it would have been a brilliant film what I mean is if the film had put the characters in a world that is not far different than our world right now, it would have helped put the audience closer to what is happening on screen and what is at the core of the film, the question of cloning. What director Roger Spottiswoode ("Tomorrow Never Dies") does though is tell us one thing and then show us another he puts us in a world where helicopters can transform into jet planes, where instead of ammo firing guns there are laser guns, and holographic displays for football games. With these things he's just put us not in the near future, but way "out there". And but doing that the points and issues brought up by the film do not him home well enough. Also the suspension of disbelief is now greater since we now have to believe that cloning technology is perfected to the point where a human can be cloned in two hours plus that there are helicopters that can turn into jet planes and that there are laser guns. I think Spottiswoode seriously dropped the ball here. He should have said that it was in the not so distant future then set it up just like that, it would have made the film's depiction of the cloning much more frightening.
Lets not forget though that this is an action film and there is action in the film. Like Spottiswoode previous action film Tomorrow Never Dies, the action is pretty flat in this film. Spottiswoode does not know how to do action well. The action is flat and at times yawn inducing. A car chase is shot early on in the film and that was a dud. The laser gun fights were, well, laser gun fights that looked as exciting as some cutting room floor stuff from the original Star Wars film. It's enough action to carry the film along, but it sure isn't exciting enough to carry the film by itself thank goodness for the good core ideas about cloning.
The actors seem to do what they can with the film. Arnie is Arnie. This isn't one of his best performances. It also isn't one of his worst. He is serviceable and likeable on screen. I wish Arnie would return to the classic style Arnie and make movies like T2, Total Recall, or even something like Predator. Neo-Arnie is a little too soft for my tastes. Worth mentioning is actress Sara Wynter as Talia. Talia is one of the agents working for Drucker's corporation trying to eliminate Adam. Wynter is does pretty well with her part and it was always entertaining to see her on screen.
The 6th Day is an average movie that eludes my recommendation for a big screen showing at full price. But, if you see it at a cheap matinee or on video it will be a decent flick to see. The ideas brought up about cloning are good conversation items and it is nice to see Arnie back on the screen doing something better than that hellacious (pun intended) End of Days.

I wrote Part 1 of this series back in October 1999 for the LinuxPlanet web site,
but the editors decided not to publish the rest of the series. Since then, many
people have asked for the continuation. This article is Part 2.
Part 1 of the series discussed my early experiences with the spam problem, first
on Usenet and then in my e-mail box. I talked about how to set up a mail filter
program and how to have it parse incoming messages. I discussed splitting up
the header into logical lines and why this is necessary. For the details and
the Perl code, you can read the original article.
I also talked about my filtering philosophy, which is to blacklist the domains
that send me a lot of spam, and reject mail from those domains.
One way to handle domains might have been to take the To: address
in the message and strip off the host name. However, this is impossible because
a host name is a domain. perl.com is both a host name
and a domain; www.perl.com is both a host name and a domain, and
so is chocolaty-goodness.www.perl.com . In practice, though, it's
easy to use a simple heuristic:
-
Split the host name into components.
-
If the last component is
com , edu , gov ,
net , or org , then the domain name is the last two components.
-
Otherwise, the domain name is the last three components
The theory is that if the final component is not a generic top-level domain
like com , it is probably a two-letter country code. Most countries
imitate the generic space at the second level of their domain. For example,
the United Kingdom has ac.uk , co.uk , and org.uk
corresponding to edu , com , and org , so
when I get mail from<EMAIL_ADDRESS>, I want to
recognize the domain as ox.ac.uk (Oxford University), not ac.uk .
Of course, this is a heuristic, which is a fancy way of saying that it doesn't
work. Many top-level domains aren't divided up at the third level the way I
assumed. For example, the to domain has no organization at all,
the same as the com domain. If I get mail from hot.spama.to ,
my program will blacklist that domain only, not realizing that it's part of
the larger spama.to domain owned by the same people. So far, however,
this has never come up.
And I didn't include mil in my list of exceptions. However, I've
never gotten spam from a mil .
Eventually the domain registration folks will introduce a batch of new generic
top-level domains, such as .firm and .web . But they've
been getting ready for it since 1996; they're still working up to it; and I
might grow old and die waiting for it to happen. (See http://www.gtld-mou.org/ for more information.)
For all its problems, this method has worked just fine for a long time because
hardly any of the problems ever actually come up. There's a moral here: The
world is full of terrifically over-engineered software. Sometimes you can waste
a lot of time trying to find the perfect solution to a problem that only needs
to be partially solved. Or as my friends at MIT used to say, ``Good enough for
government work!''
Here's the code for extracting the domain:
1 my ($user, $site) = $s =~ /(.*)@(.*)/;
2 next unless $site;
3 my @components = split(/\./, $site);
4 my $n_comp = ($components[-1] =~ /^edu|com|net|org|gov$/) ? 2 : 3;
5 my $domain = lc(join '.', @components[-$n_comp .. -1]);
6 $domain =~ s/^\.//; # Remove leading . if there is one.
The sender's address is in $s . I extract the site name from the
address with a simple pattern match, which is also a wonderful example of the
"good enough" principle. Messages appear in the comp.lang.perl.misc
newsgroup every week asking for a pattern that matches an e-mail address. The
senders get a lot of very long complicated answers, or are told that it can't
be done. And yet there it is. Sure, it doesn't work. Of course, if you get mail
addressed to ``<EMAIL_ADDRESS>it's going to barf. Of course, if you get source-routed
mail with an address like<EMAIL_ADDRESS>it isn't going to work.
But guess what? Those things never happen. A production mail server has to
deal with these sorts of fussy details, but if my program fails to reject some
message as spam because it made an overly simple assumption about the format
of the mail addresses, there's no harm done.
On line 2, we skip immediately to the next address if there's no site name,
since it now appears that this wasn't an address at all. Line 3 breaks the site
name up into components; thelonious.new.ox.ac.uk is broken into
thelonious , new , ox , ac ,
and uk .
Line 4 is the nasty heuristic: It peeks at the last component, in this case
uk , and if it's one of the magic five (edu , com ,
net , org , or gov ), it sets $n_comp
to 2; otherwise to 3. $n_comp is going to be the number of components
that are part of the domain, so the domain of saul.cis.upenn.edu
is upenn.edu , and the domain of thelonious.new.ox.ac.uk
is ox.ac.uk .
To get the last component, we subscript the component array @components
with -1 . -1 as an array subscript means to get the
last element of the array. Similarly, -2 means to get the next-to-last element.
In this case, the last component is uk , which doesn't match the
pattern, so $n_comp is 3.
On line 5, -$n_comp .. -1 is really -3 .. -1 , which
is the list -3, -2, -1 . We use a Perl feature called a "list
slice" to extract just the elements -3, -2, and -1 from the @components
array. The syntax
@components[(some list)]
invokes this feature. The list is taken to be a list of subscripts, and the
elements of @components with those subscripts are extracted, in order. This is why you
can write
($year, $month, $day) = (localtime)[5,4,3];
to extract the year, month, and day from localtime , in that order--it's
almost the same feature. Here we're extracting elements -3 (the third-to-last),
-2 (the second-to-last), and -1 (the last) and joining them together again.
If $n_comp had been 2, we would have gotten elements -2 and -1
only.
Finally, line 6 takes care of a common case in which the heuristic doesn't
work. If we get mail from alcatel.at , and try to select the last
three components, we'll get one undefined component--because there were really
only two there--and the result of the join will be .alcatel.at ,
with a bogus null component on the front. Line 6 looks to see if there's an
extra period on the front of the domain, and if so, it chops it off.
I've extracted the domain name. The obvious thing to do is to have a big
hash with every bad domain in it, and to look this domain up in the hash to
see if it's there. Looking things up in a hash is very fast.
However, that's not what I decided to do. Instead, I have a huge file with
a regex in it for every bad domain, and I take the domain in question
and match it against all the patterns in the file. That's a lot slower. A lot
slower. Instead of looking up the domain instantaneously, it takes 0.24 seconds
to match the patterns.
Some people might see that and complain that it was taking a thousand times
as long as it should. And maybe that's true. But the patterns are more flexible,
and what's a quarter of a second more or less? The mail filter handled 2,211
messages in the month of January. At 0.24 seconds each, the pattern matching
is costing me less than 9 minutes per month.
So much for the downside. What's the upside? I get to use patterns. That's
a big upside.
I have a pattern in my pattern file that rejects any mail from anyone who
claims that their domain is all digits, such as 12345.com. That would have been
impossible with a hash. I have a pattern that rejects mail from anyone with
"casino" in their domain. That took care of spam from Planetrockcasino.com
and Romancasino.com before I had ever heard of those places. Remember that I
only do the pattern matching on the domain, so if someone sent me mail from
casino.ox.ac.uk , it would get through.
The regexes actually do have a potential problem: The patterns are in the
file, one pattern per line. Suppose I'm adding patterns to the file and I leave
a blank line by mistake. Then some mail arrives. The filter extracts the domain
name of the sender and starts working through the pattern file. 0.24 seconds
later, it gets to the blank line.
What happens when you match a string against the empty pattern? It matches,
that's what. Every string matches the empty pattern. Since the patterns are
assumed to describe mail that I don't want to receive, the letter is
rejected. So is the next letter. So is every letter. Whoops.
It's tempting to say that I should just check for blank patterns and skip
them if they're there, but that won't protect me against a line that has only
a period and nothing else--that will also match any string.
Instead, here's what I've done:
$MATCHLESS = "qjdhqhd1!&@^#^*&!@#";
if ($MATCHLESS =~ /$badsite_pat/i) {
&defer("The bad site pattern matched `$MATCHLESS',
so I assume it would match anything. Deferring...\n");
}
Since the patterns are designed to identify bad domain names, none of them
should match qjdhqhd1!&@^#^*&!@# . If a pattern does
match that string, it probably also matches a whole lot of other stuff that
it shouldn't. In that case, the program assumes that the pattern file is corrupt,
and defers the delivery. This means that it tells qmail that it
isn't prepared to deliver the mail at the present time, and that qmail
should try again later on. qmail will keep trying until it gets
through or until five days have elapsed, at which point it gives up and bounces
the message back to the sender. Chances are that I'll notice that I'm not getting
any mail sometime before five days have elapsed, look in the filter log file,
and fix the pattern file. As qmail retries delivery, the deferred
messages will eventually arrive.
Deferring a message is easy when your mailer is qmail . Here's
the defer subroutine in its entirety:
sub defer {
my $msg = shift;
carp $msg;
exit 111;
}
When qmail sees the 111 exit status from the filter program,
it interprets it as a request to defer delivery. (Similarly, 100 tells qmail
that there was a permanent failure and it should bounce the message back to
the sender immediately. The normal status of 0 means that delivery was successful.)
I would still be in trouble if I installed com as a pattern in the pattern file, because it
matches more domains than it
should, but the
MATCHLESS test doesn't catch it. But unlike the blank line problem, it's never come
up, so I've decided to deal with it when it arises.
In addition to filtering the From: , Reply-To: , and
envelope sender addresses, I also look through the list of forwarding hosts
for bad domains. The From: and Reply-To: headers are
easy to forge: The sender can put whatever they want in those fields and spammers
usually do. But the Received: fields are a little different. When
computer A sends a message to computer B, the receiving computer B
adds a Received: header to the message, recording who it is, when
it received the message, and from whom. If the message travels through several
computers, there will be several received lines, with the earliest one at the
bottom of the header and the later ones added above it. Here's a typical set
of Received: lines:
1 Received: (qmail 7131 invoked by uid 119); 22 Feb 1999 22:01:59 -0000
2 Received: (qmail 7124 invoked by uid 119); 22 Feb 1999 22:01:58 -0000

This is from a message that someone sent to<EMAIL_ADDRESS>,
an old address of mine. Apparently the sender's mail client, in localhost.cucs.org ,
initially passed the message to the organization's mail server, mail.cucs.org .
The mail server then added the lines 14-16 to the message header.
The mail server then delivered the message to saul.cis.upenn.edu
over the Internet. saul added lines 11-13. Notice that the time
on line 13 is 128 seconds after the time on line 13. This might mean that the
message sat on mail.cucs.org for 128 seconds before it was delivered
to saul , or it might mean that the two computers' clocks are not
properly synchronized.
When the mail arrived on saul , the mailer there discovered that
I have a .forward file there directing delivery to<EMAIL_ADDRESS>.
saul needed to forward the message to<EMAIL_ADDRESS>.
However, most machines in the University of Pennsylvania CIS department do not
deliver Internet mail themselves. Instead, they forward all mail to a departmental
mail hub, linc , which takes care of delivering all the mail outside
the organization. Lines 8-10 were added by linc when the mail was
delivered to it by saul .
linc looked up op.net in the domain name service and discovered
that the machine pisarro.op.net was receiving mail for the
op.net domain. Line 7 was added by pisarro when it received the
mail from linc .
I don't know why pisarro then delivered the message to renoir ,
but we know that it did, because line 6 says so.
qmail on plover.com added lines 4-5 when the mail
was delivered from renoir . Then the final three lines, 1-3, were
added by qmail for various local deliveries to mjd ,
then mjd-filter (which runs my spam filter), and finally, mjd-filter-deliver ,
which is the address that actually leads to my mailbox.
What can we learn from all this? The Received: lines have a record
of every computer that the message passed through on its way to being delivered.
And unlike the From: and Reply-To: lines, it really
does record where the message has been.
Suppose the original sender, at localhost.cucs.org had wanted
to disguise the message's origin. Let's call him Bob. Bob cannot prevent cucs.org
from being mentioned in the message header. Why? Because there it is in line
11. Line 11 was put there by saul.cis.upenn.edu , not by Bob, who
has no control over computers in the upenn.edu domain.
Bob can try to confuse the issue by adding spurious Received:
lines, but he can't prevent the other computers from adding the correct
ones.
Now, when spammers send spam, they often forge the From: and
the Reply-To: lines so that people don't know who they are and
can't come and kill them. But they can't forge the Received: lines
because it's another computer that puts those in. So when we're searching for
domains to check against the list of bad domain patterns, we should look through
the Received: lines too.
The difficulty with that is that there's no standard for what a Received:
line should look like or what should be in it, and every different mailer does
its own thing. You can see this in the example above. We need a way to go over
the Received: lines and look for things that might be domains.
This is just the sort of thing that Perl regexes were designed for.
1 sub forwarders {
2 return @forwarders if @forwarders;
3
4 @forwarders =
5 grep { /[A-Za-z]/ } ($H{'Received'} =~ m/(?:[\w-]+\.)+[\w-]+/g);
6
7 @forwarders = grep { !/(\bplover\.com|\bcis\.upenn\.edu|\bpobox\.com|\bop\.net)$/i }
@forwarders;
8
9 foreach $r (@forwarders) {
10 $r{lc $r} = 1;
11 }
12
13 @forwarders = keys %r;
14
15 return @forwarders;
16 }
The message header has already been parsed and placed into the %H
hash. $H{Received} contains the concatenation of all the Received
lines in the whole message. The purpose of the forwarders() function
is to examine $H{Received} , extract all the domain names it can
find, and place them in the array @forwarders .
Lines 4-5 are the heart of this process. Let's look a little more closely.
$H{'Received'} =~ m/(?:[\w-]+\.)+[\w-]+/g
This does a pattern match in the Received: lines. [\w-]
looks for a single letter, digit, underscore, or hyphen, while [\w-]+
looks for a sequence of such characters, such as saul or apple-gunkies .
This is a domain component. [\w-]+\. looks for a domain component
followed by a period, like saul. or apple-gunkies. .
Ignore the ?: for the time being. Without it, the pattern is
([\w-]+\.)+[\w-]+ , which means a domain component followed by a
period, then another domain component followed by another period, and so on,
and ending with a domain component and no period. So this is a pattern that
will match something that looks like a domain.
The /g modifier on the match instructs Perl to find all matching substrings
and to return a list of them. Perl will look through
the
Received: headers, pulling out all the things that look like domains, making them
into a list, and returning the list of domains.
Another example of this feature:
$s = "Timmy is 7 years old and he lives at 350 Beacon St. Boston, MA 02134"
@numbers = ($s =~ m/\d+/g);
Now @numbers contains (7, 350, 02134).
I still haven't explained that ?: . I have to confess to a lie. Perl only returns the list of
matching
substrings if the pattern contains no parentheses. If the pattern contains
parentheses, the parentheses cause part of the string to be captured into
the special
$1 variable, and the match returns a list of the $1 s instead of a list of
the entire matching substrings. If I'd done
"saul.cis.upenn.edu plover.com" =~ m/([\w-]+\.)+[\w-]+/g
instead, I would have gotten the list ("saul.cis.upenn.",
"plover.") , which are the $1 's, because the com
parts match the final [\w-]+ , which is not in parentheses. The
?: in the real pattern is nothing more than a switch to tell Perl
not to use $1 ; . Since $1 isn't being used, we get
the default behavior, and the match returns a list of everything that matched.
4 @forwarders =
5 grep { /[A-Za-z]/ } ($H{'Received'} =~ m/(?:[\w-]+\.)+[\w-]+/g);
The pattern match generates a list of things that might be domains. The
list initially looks like:
renoir.op.net <IP_ADDRESS>
plover.com
pisarro.op.net pisarro.op.net <IP_ADDRESS> renoir.op.net 1.18 mail.op.net
linc.cis.upenn.edu LINC.CIS.UPENN.EDU <IP_ADDRESS> pisarro.op.net 1.1 op.net
saul.cis.upenn.edu SAUL.CIS.UPENN.EDU <IP_ADDRESS>
linc.cis.upenn.edu 8.8.5 8.8.5

As you can see, it contains a lot of junk. Most notably, it contains several
occurrences of 8.8.5 , because the upenn.edu mailer
was Sendmail version 8.8.5. There are also some IP addresses that we won't be
able to filter, and some other things that look like version numbers. The grep
filters this list of items and passes through only those that contain at least
one letter, discarding the entirely numeric ones.

The rest of the function is just a little bit of cleanup. Line 7 discards
several domain names that aren't worth looking at because they appear so
often:
7 @forwarders = grep { !/(\bplover\.com|\bcis\.upenn\.edu|\bpobox\.com|\bop\.net)$/i }
@forwarders;
Plover.com is my domain, and it's going to appear in all my mail, so there's
no point in checking it. I worked at the University of Pennsylvania for four
and a half years, and I get a lot of mail forwarded from there, so there's no
point in checking cis.upenn.edu domains either. Similarly, I subscribe
to the Pobox.com lifetime e-mail forwarding service, and I get a lot of mail
forwarded through there. op.net is my ISP domain name, which handles
mail for me when Plover is down. Line 7 discards all these domains from the
@forwarders list, leaving only the following:
mail.cucs.org cucs-a252.cucs.org
localhost.cucs.org
mail.cucs.org
Lines 9-13 now discard duplicate items, using a common Perl idiom:
9 foreach $r (@forwarders) {
10 $r{lc $r} = 1;
11 }
12
13 @forwarders = keys %r;
We use the remaining items as keys in a hash. Since a hash can't have the
same key twice, the duplicate mail.cucs.org has no effect on the
hash, which ends up with the keys, mail.cucs.org , cucs-a252.cucs.org
and localhost.cucs.org . The values associated with these keys are
each "1," which doesn't matter. When we ask Perl for a list of keys
on line 13, we get each key exactly once.
Finally, line 15 returns the list of forwarders to whomever needed it.
There's one little thing I didn't discuss:
2 return @forwarders if @forwarders;
The first thing the function does is check to see if it's already processed
the Received: lines and the computer @forwarders .
If so, it returns the list without computing it over again. That way I can just
call forwarders() anywhere in my program that I need a list of
forwarders, without worrying that I might be doing the same work more than once;
the forwarders() function guarantees to return immediately after
the first time I call it.
Because of the long delay, I'll repeat the quiz from the first article:
What's wrong with this header line?
Received: from login_2961.sayme2.net (mail.sayme2.net[<IP_ADDRESS>])
by sayme2.net (8.8.5/8.7.3) with SMTP id XAA02040
for<EMAIL_ADDRESS>Thu, 28 August 1997 15:51:23 -0700 (EDT)
The story's not over. In the next article, I'll talk about some other rules
I used to filter the spam; one of them would have thrown out messages when it
saw a line like the one above. Another one throws out mail when there's no To:
line in the message--a likely sign of bulk mail.
I'll also tell a cautionary tale of how I might have lost a lot of money
because my system worked too well, and how I found out that sometimes, you want to get
unsolicited bulk mail. |
