Summary
Often, during a penetration test on web applications, we come up against many error codes generated from applications or web servers. It's possible to cause these errors to be displayed by using a particular requests, either specially crafted with tools or created manually. These codes are very useful to penetration testers during their activities, because they reveal a lot of information about databases, bugs, and other technological components directly linked with web applications.
This section analyses the more common codes (error messages) and bring into focus their relevance during a vulnerability assessment. The most important aspect for this activity is to focus one's attention on these errors, seeing them as a collection of information that will aid in the next steps of our analysis. A good collection can facilitate assessment efficiency by decreasing the overall time taken to perform the penetration test.
Attackers sometimes use search engines to locate errors that disclose information. Searches can be performed to find any erroneous sites as random victims, or it is possible to search for errors in a specific site using the search engine filtering tools as described in 4.2.1 Conduct Search Engine Discovery and Reconnaissance for Information Leakage (OTG-INFO-001)
Web Server Errors
A common error that we can see during testing is the HTTP 404 Not Found. Often this error code provides useful details about the underlying web server and associated components. For example:
Not Found
The requested URL /page.html was not found on this server.
Apache/2.2.3 (Unix) mod_ssl/2.2.3 OpenSSL/0.9.7g DAV/2 PHP/5.1.2 Server at localhost Port 80
This error message can be generated by requesting a non-existent URL. After the common message that shows a page not found, there is information about web server version, OS, modules and other products used. This information can be very important from an OS and application type and version identification point of view.
Other HTTP response codes such as 400 Bad Request, 405 Method Not Allowed, 501 Method Not Implemented, 408 Request Time-out and 505 HTTP Version Not Supported can be forced by an attacker. When receiving specially crafted requests, web servers may provide one of these error codes depending on their HTTP implementation.
Testing for disclosed information in the Web Server error codes is related testing for information disclosed in the HTTP headers as described in the section Fingerprint Web Server (OTG-INFO-002).
Application Server Errors
Application errors are returned by the application itself, rather than the web server. These could be error messages from framework code (ASP, JSP etc.) or they could be specific errors returned by the application code. Detailed application errors typically provide information of server paths, installed libraries and application versions.
Database Errors
Database errors are those returned by the Database System when there is a problem with the query or the connection. Each Database system, such as MySQL, Oracle or MSSQL, has their own set of errors. Those errors can provide sensible information such as Database server IPs, tables, columns and login details.
In addition, there are many SQL Injection exploitation techniques that utilize detailed error messages from the database driver, for in depth information on this issue see Testing for SQL Injection (OTG-INPVAL-005) for more information.
Web server errors aren't the only useful output returned requiring security analysis. Consider the next example error message:
Microsoft OLE DB Provider for ODBC Drivers (0x80004005)
[DBNETLIB][ConnectionOpen(Connect())] - SQL server does not exist or access denied
What happened? We will explain step-by-step below.
In this example, the 80004005 is a generic IIS error code which indicates that it could not establish a connection to its associated database. In many cases, the error message will detail the type of the database. This will often indicate the underlying operating system by association. With this information, the penetration tester can plan an appropriate strategy for the security test.
By manipulating the variables that are passed to the database connect string, we can invoke more detailed errors.
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC Access 97 ODBC driver Driver]General error Unable to open registry key 'DriverId'
In this example, we can see a generic error in the same situation which reveals the type and version of the associated database system and a dependence on Windows operating system registry key values.
Now we will look at a practical example with a security test against a web application that loses its link to its database server and does not handle the exception in a controlled manner. This could be caused by a database name resolution issue, processing of unexpected variable values, or other network problems.
Consider the scenario where we have a database administration web portal, which can be used as a front end GUI to issue database queries, create tables, and modify database fields. During the POST of the logon credentials, the following error message is presented to the penetration tester. The message indicates the presence of a MySQL database server:
Microsoft OLE DB Provider for ODBC Drivers (0x80004005)
[MySQL][ODBC 3.51 Driver]Unknown MySQL server host
If we see in the HTML code of the logon page the presence of a hidden field with a database IP, we can try to change this value in the URL with the address of database server under the penetration tester's control in an attempt to fool the application into thinking that the logon was successful.
Another example: knowing the database server that services a web application, we can take advantage of this information to carry out a SQL Injection for that kind of database or a persistent XSS test.

Remediation
Error Handling in IIS and ASP .net
ASP .net is a common framework from Microsoft used for developing web applications. IIS is one of the commonly used web servers. Errors occur in all applications, developers try to trap most errors but it is almost impossible to cover each and every exception (it is however possible to configure the web server to suppress detailed error messages from being returned to the user).
IIS uses a set of custom error pages generally found in c:\winnt\help\iishelp\common to display errors like '404 page not found' to the user. These default pages can be changed and custom errors can be configured for IIS server. When IIS receives a request for an aspx page, the request is passed on to the dot net framework.
There are various ways by which errors can be handled in dot net framework. Errors are handled at three places in ASP .net:
- Inside Web.config customErrors section
- Inside global.asax Application_Error Sub
- At the the aspx or associated codebehind page in the Page_Error sub
Handling errors using web.config
<customErrors defaultRedirect="myerrorpagedefault.aspx" mode="On|Off|RemoteOnly">
<error statusCode="404" redirect="myerrorpagefor404.aspx"/>
<error statusCode="500" redirect="myerrorpagefor500.aspx"/>
</customErrors>
mode="On" will turn on custom errors. mode=RemoteOnly will show custom errors to the remote web application users. A user accessing the server locally will be presented with the complete stack trace and custom errors will not be shown to him.
All the errors, except those explicitly specified, will cause a redirection to the resource specified by defaultRedirect, i.e., myerrorpagedefault.aspx. A status code 404 will be handled by myerrorpagefor404.aspx.
Handling errors in Global.asax
When an error occurs, the Application_Error sub is called. A developer can write code for error handling/page redirection in this sub.
Private Sub Application_Error (ByVal sender As Object, ByVal e As System.EventArgs)
Handles MyBase.Error
End Sub
Handling errors in Page_Error sub
This is similar to application error.
Private Sub Page_Error (ByVal sender As Object, ByVal e As System.EventArgs)
Handles MyBase.Error
End Sub
Error hierarchy in ASP .net
Page_Error sub will be processed first, followed by global.asax Application_Error sub, and, finally, customErrors section in web.config file.
Information Gathering on web applications with server-side technology is quite difficult, but the information discovered can be useful for the correct execution of an attempted exploit (for example, SQL injection or Cross Site Scripting (XSS) attacks) and can reduce false positives.
How to test for ASP.net and IIS Error Handling
Fire up your browser and type a random page name
http:\\www.mywebserver.com\anyrandomname.asp
If the server returns:
The page cannot be found
Internet Information Services
it means that IIS custom errors are not configured. Please note the .asp extension.
Also test for .net custom errors. Type a random page name with aspx extension in your browser:
http:\\www.mywebserver.com\anyrandomname.aspx
If the server returns
Server Error in '/' Application.
--------------------------------------------------------------------------------
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.
custom errors for .net are not configured.
Error Handling in Apache
Apache is a common HTTP server for serving HTML and PHP web pages. By default, Apache shows the server version, products installed and OS system in the HTTP error responses.
Responses to the errors can be configured and customized globally, per site or per directory in the apache2.conf using the ErrorDocument directive [2]
ErrorDocument 404 “Customized Not Found error message”
ErrorDocument 403 /myerrorpagefor403.html
ErrorDocument 501 http://www.externaldomain.com/errorpagefor501.html
Site administrators are able to manage their own errors using .htaccess file if the global directive AllowOverride is configured properly in apache2.conf [3]
The information shown by Apache in the HTTP errors can also be configured using the directives ServerTokens [4] and ServerSignature [5] at apache2.conf configuration file. “ServerSignature Off” (On by default) removes the server information from the error responses, while ServerTokens [ProductOnly|Major|Minor|Minimal|OS|Full] (Full by default) defines what information has to be shown in the error pages.
Error Handling in Tomcat
Tomcat is a HTTP server to host JSP and Java Servlet applications. By default, Tomcat shows the server version in the HTTP error responses.
Customization of the error responses can be configured in the configuration file web.xml.
<error-page>
<error-code>404</error-code>
<location>/myerrorpagefor404.html</location>
</error-page>

To report a problem with this extracted sample, visit https://issuetracker.google.com/issues/new?component=192708. (##) Suppressing You can suppress false positives using one of the following mechanisms: * Adding the suppression attribute `tools:ignore="ExportedPreferenceActivity"` on the problematic XML element (or one of its enclosing elements). You may also need to add the following namespace declaration on the root element in the XML file if it's not already there: `xmlns:tools="http://schemas.android.com/tools"`. ```xml <?xml version="1.0" encoding="UTF-8"?> <manifest xmlns:tools="http://schemas.android.com/tools"> ... <activity tools:ignore="ExportedPreferenceActivity" .../> ... </manifest> ``` * Using a suppression annotation like this on the enclosing element: ```kt // Kotlin @Suppress("ExportedPreferenceActivity") fun method() { problematicStatement() } ``` or ```java // Java @SuppressWarnings("ExportedPreferenceActivity") void method() { problematicStatement(); } ``` * Using a suppression comment like this on the line above: ```kt //noinspection ExportedPreferenceActivity problematicStatement() ``` * Using a special `lint.xml` file in the source tree which turns off the check in that folder and any sub folder. A simple file might look like this: ```xml <?xml version="1.0" encoding="UTF-8"?> <lint> <issue id="ExportedPreferenceActivity" severity="ignore" /> </lint> ``` Instead of `ignore` you can also change the severity here, for example from `error` to `warning`. You can find additional documentation on how to filter issues by path, regular expression and so on [here](https://googlesamples.github.io/android-custom-lint-rules/usage/lintxml.md.html). * In Gradle projects, using the DSL syntax to configure lint. For example, you can use something like ```gradle lintOptions { disable 'ExportedPreferenceActivity' } ``` In Android projects this should be nested inside an `android { }` block. * For manual invocations of `lint`, using the `--ignore` flag: ``` $ lint --ignore ExportedPreferenceActivity ...` ``` * Last, but not least, using baselines, as discussed [here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).

The CN Tower
You know you are in Toronto when you see the needle topped structure that is the CN Tower. A trip to the top to experience the spectacular views of the
city is essential. A glass elevator takes you to the summit in an impressive 58 seconds. From here the brave can venture across the glass floor, with a
vertigo inducing view straight down to the ground, or you can go even higher to the Sky Pod, or eat at the world’s highest revolving restaurant. Be
aware that you may need to queue for a while, particularly in peak months like June and July.
Rogers Centre
Situated just outside CN Tower, this versatile stadium is home to the Major League Baseball team the Toronto Blue Jays, but what is most impressive is how it
can be configured for other sports and events with its movable stands, artificial turf and retractable roof. The tour of the centre is extremely well delivered
and interesting, you even get to stand on the pitch if the schedule permits.
Niagara Falls
Toronto is an excellent base for excursions further afield. Within a two hour drive from the city you reach the natural beauty that is Niagara Falls. A trip
behind the falls is highly recommended. An elevator takes you down through the bedrock to tunnels that lead to observation decks that provide remarkable views
of the waterfall. The thunderous cacophony as you walk through the tunnels is awe inspiring. The Maid of the Mist is another excellent way of experiencing the
falls. The Maid of the Mist boat takes you past the American Falls, and then onto the famous horseshoe Canadian side. It is here that you begin to feel the
inexorable force of the water, I’ve never been in a storm at sea, but I imagine this is what it feels like. The trip lasts approximately 30 minutes, and even
with the hooded raincoat, you will get wet!
Many planned excursions also include a trip to Niagara-on-the-Lake, this picturesque lakeside village with its collection of shops, restaurants, galleries
and buildings is well worth a visit.

UDP
Section: Linux Programmer's Manual (7)
Updated: 2013-07-31
Index
Return to Main Contents
NAME
udp - User Datagram Protocol for IPv4
SYNOPSIS
#include <sys/socket.h>
#include <netinet/in.h>
#include <netinet/udp.h>
udp_socket = socket(AF_INET, SOCK_DGRAM, 0);
DESCRIPTION
This is an implementation of the User Datagram Protocol
described in RFC 768.
It implements a connectionless, unreliable datagram packet service.
Packets may be reordered or duplicated before they arrive.
UDP generates and checks checksums to catch transmission errors.
When a UDP socket is created,
its local and remote addresses are unspecified.
Datagrams can be sent immediately using
sendto(2)
or
sendmsg(2)
with a valid destination address as an argument.
When
connect(2)
is called on the socket, the default destination address is set and
datagrams can now be sent using
send(2)
or
write(2)
without specifying a destination address.
It is still possible to send to other destinations by passing an
address to
sendto(2)
or
sendmsg(2).
In order to receive packets, the socket can be bound to a local
address first by using
bind(2).
Otherwise, the socket layer will automatically assign
a free local port out of the range defined by
/proc/sys/net/ipv4/ip_local_port_range
and bind the socket to
INADDR_ANY.
All receive operations return only one packet.
When the packet is smaller than the passed buffer, only that much
data is returned; when it is bigger, the packet is truncated and the
MSG_TRUNC
flag is set.
MSG_WAITALL
is not supported.
IP options may be sent or received using the socket options described in
ip(7).
They are processed by the kernel only when the appropriate
/proc
parameter
is enabled (but still passed to the user even when it is turned off).
See
ip(7).
When the
MSG_DONTROUTE
flag is set on sending, the destination address must refer to a local
interface address and the packet is sent only to that interface.
By default, Linux UDP does path MTU (Maximum Transmission Unit) discovery.
This means the kernel
will keep track of the MTU to a specific target IP address and return
EMSGSIZE
when a UDP packet write exceeds it.
When this happens, the application should decrease the packet size.
Path MTU discovery can be also turned off using the
IP_MTU_DISCOVER
socket option or the
/proc/sys/net/ipv4/ip_no_pmtu_disc
file; see
ip(7)
for details.
When turned off, UDP will fragment outgoing UDP packets
that exceed the interface MTU.
However, disabling it is not recommended
for performance and reliability reasons.
Address format
UDP uses the IPv4
sockaddr_in
address format described in
ip(7).
Error handling
All fatal errors will be passed to the user as an error return even
when the socket is not connected.
This includes asynchronous errors
received from the network.
You may get an error for an earlier packet
that was sent on the same socket.
This behavior differs from many other BSD socket implementations
which don't pass any errors unless the socket is connected.
Linux's behavior is mandated by
RFC 1122.
For compatibility with legacy code, in Linux 2.0 and 2.2
it was possible to set the
SO_BSDCOMPAT
SOL_SOCKET
option to receive remote errors only when the socket has been
connected (except for
EPROTO
and
EMSGSIZE).
Locally generated errors are always passed.
Support for this socket option was removed in later kernels; see
socket(7)
for further information.
When the
IP_RECVERR
option is enabled, all errors are stored in the socket error queue,
and can be received by
recvmsg(2)
with the
MSG_ERRQUEUE
flag set.
/proc interfaces
System-wide UDP parameter settings can be accessed by files in the directory
/proc/sys/net/ipv4/.
- udp_mem (since Linux 2.6.25)
-
This is a vector of three integers governing the number
of pages allowed for queueing by all UDP sockets.
-
- min
-
Below this number of pages, UDP is not bothered about its
memory appetite.
When the amount of memory allocated by UDP exceeds
this number, UDP starts to moderate memory usage.
- pressure
-
This value was introduced to follow the format of
tcp_mem
(see
tcp(7)).
- max
-
Number of pages allowed for queueing by all UDP sockets.
-
Defaults values for these three items are
calculated at boot time from the amount of available memory.
- udp_rmem_min (integer; default value: PAGE_SIZE; since Linux 2.6.25)
-
Minimal size, in bytes, of receive buffers used by UDP sockets in moderation.
Each UDP socket is able to use the size for receiving data,
even if total pages of UDP sockets exceed
udp_mem
pressure.
- udp_wmem_min (integer; default value: PAGE_SIZE; since Linux 2.6.25)
-
Minimal size, in bytes, of send buffer used by UDP sockets in moderation.
Each UDP socket is able to use the size for sending data,
even if total pages of UDP sockets exceed
udp_mem
pressure.
Socket options
To set or get a UDP socket option, call
getsockopt(2)
to read or
setsockopt(2)
to write the option with the option level argument set to
IPPROTO_UDP.
Unless otherwise noted,
optval
is a pointer to an
int.
- UDP_CORK (since Linux 2.5.44)
-
If this option is enabled, then all data output on this socket
is accumulated into a single datagram that is transmitted when
the option is disabled.
This option should not be used in code intended to be
portable.
Ioctls
These ioctls can be accessed using
ioctl(2).
The correct syntax is:
-
int value;
error = ioctl(udp_socket, ioctl_type, &value);
- FIONREAD (SIOCINQ)
-
Gets a pointer to an integer as argument.
Returns the size of the next pending datagram in the integer in bytes,
or 0 when no datagram is pending.
Warning:
Using
FIONREAD,
it is impossible to distinguish the case where no datagram is pending
from the case where the next pending datagram contains zero bytes of data.
It is safer to use
select(2),
poll(2),
or
epoll(7)
to distinguish these cases.
- TIOCOUTQ (SIOCOUTQ)
-
Returns the number of data bytes in the local send queue.
Only supported with Linux 2.4 and above.
In addition, all ioctls documented in
ip(7)
and
socket(7)
are supported.
ERRORS
All errors documented for
socket(7)
or
ip(7)
may be returned by a send or receive on a UDP socket.
- ECONNREFUSED
-
No receiver was associated with the destination address.
This might be caused by a previous packet sent over the socket.
VERSIONS
IP_RECVERR
is a new feature in Linux 2.2.

Buttons
To create a button, use the <button>
element or apply the button
class to another element such as an <a>
. You can change a button’s appearance using the button-*
modifier.
<button type="button">Default</button>
<button type="button" class="button-success">Success</button>
<button type="button" class="button-info">Info</button>
<button type="button" class="button-warning">Warning</button>
<button type="button" class="button-danger">Danger</button>
<button type="button" class="button-inverse">Inverse</button>
<button type="button" class="button button-link">Link</button>
Use the button-small
and button-big
modifiers to change the size of a button.
Use the button-block
modifier to make the button span the entire width of its parent element. You can also mix and match modifiers as needed.
Disabled buttons look like this. Set the disabled
property on <button>
elements to achieve this effect. For all other elements, apply class="disabled"
instead.
You can force buttons to have an active state by applying the active
class.
File Buttons
File inputs are notoriously hard to style properly in every browser. Shoelace offers file buttons as an alternative. These are much easier to style consistently, but come with the caveat that the name (or number) of files selected will not be automatically shown to the user. This aspect of a file button’s UX can be handled effectively with JavaScript, but this is left as an exercise for the user.
File buttons are simply <label>
elements with the button
class and a nested file input.
<label class="button">
Select File
<input type="file">
</label>

Computers have a wide range of use in almost every field of our life. They are specially used in the following fields:..
a) Office Use
b) Data analysis
c) Accounting and investment analysis.
d) Graphics and Animation
e) Education
f) Banks
g) Ticket Reservation
g) E-mailing
The work done in offices is mostly the preparation of letters, reports, memoranda, copy of advertisement, publicity, minutes, contracts, forms, notes etc. which can be done through computer in most efficient manner.
You can analyse the data through special software called spreadsheet programs. You can also prepare the product sales, profits and investment reports. You can also sort, merge and manipulate data (as needed) by accepting the data from other files.
A spreadsheet program is a software package through which you can analyse investment, inventory control, preparation of budget etc. Specialized software packages such as Tally are available to handle accounts in medium sized companies.
Accounting Programs are used for data entry, billing, inventory control, Sales Analysis. Many companies issue shares, debentures, etc. Software packages for such analysis are available at a small price, like MS-Office Suite supported by Microsoft Corporation.
Computers can be used to make drawings, graphics and movies. CorelDRAW, Illustrator, Visio 2000 and FreeLance Plus for Windows are some such software packages, which can help you in increasing your drawing capability.
In educational institutions computers are used as teaching aid, research tool and analyzing system. When computer is used as a teaching aid it is referred to as computer-assisted instruction (CAI).
Banks use computers to provide online service to customers and to answer customer queries regarding their bank balance etc. To handle cash, banks use cash dispensing machines (Asynchronous Transfer Mode(ATM)).With the use of computers, electronic transfer of funds from one account to another has become possible.
Indian Railways have computerized ticket reservation in almost all important railway stations. The computer stores all necessary information required for ticket processing such as train number, stations, distance between stations, number of seats available in each train for each class, train fare etc. The computer can also give information regarding train timings, fares etc. on telephone enquiry.
Electronic mail (E-mail) is a system whereby through computer users can exchange messages, greetings etc. with each other via Internet, at a very cheap rate. E-mail allows you to create, send, receive and store messages. You can send mail to individuals or groups with a single click.


THE GENERAL'S DAUGHTER (M). (Paramount/UIP) Director: Simon West Stars: John Travolta, Madeleine Stowe, James Cromwell, Timothy Hutton, James Woods, Clarence Williams III, Leslie Stefanson Running time: 116 minutes.
Like the superb A Few Good Men, The General's Daughter is a murder mystery that puts the military on trial and probes the rotten core of the corps. The film also similarly questions the unblinking obedience to strict codes of behaviour and disciplined adherence to "the army way" that leads to abuses.
The catalyst here is the discovery of a bound and brutally beaten body on a military base. The victim is a female officer and psychological warfare expert. She is also the only child of legendary general Joe Campbell (James Cromwell, from Babe, etc), a highly decorated officer who is about to retire from the military and take up a very high profile position in public life as a vice presidential candidate. Campbell is anxious to avoid any hint of scandal, and wants the murder quietly and quickly investigated before the FBI is called in.
Assigned the unenviable and politically prickly task is CID investigator Paul Brenner (John Travolta), who has special powers of arrest. We quickly learn that Brenner is something of a maverick, who shoots first and asks questions later, and who also has a healthy disdain for following military protocol. Assisting the investigation is Sarah Sunhill (Madeleine Stowe), a rape specialist with whom Brenner had an affair many years earlier. The pair trample through a minefield of military secrets, long buried scandals, corruption, and sordid sex that eventually leads all the way to West Point. They also uncover a list of high profile suspects that includes the dead woman's boss Colonel Moore (a wonderfully smarmy James Woods) and the general's personal aide (Clarence Williams III, from the original Mod Squad).
Based on Nelson De Mille's best selling novel, The General's Daughter is a somewhat brutal and ugly film, with an emphasis on graphic violence and sordid sex, that will do little for the image of the army. The clever and sinuous plot features a number of red herrings that will keep audiences hooked until the denouement. One suspects that veteran script doctor and dual Oscar winning writer William Goldman is largely responsible for polishing the crackling dialogue, especially the wonderful interrogation scene between Brenner and Moore which snaps with clever barbs and verbal one- upmanship.
Director Simon West (who burst onto the screen with the sensational action thriller Con Air) leaves behind the spectacular pyrotechnics and spectacular action sequences of his debut to concentrate more on character and atmosphere here. Nonetheless his direction is proficient and he maintains a keen level of suspense throughout the film.
Travolta brings a dangerous edge and rare intensity to his performance as the driven Brenner, while Stowe is both tough yet vulnerable as Sunhill. Cromwell brings dignity and class to his role as the veteran general who has devoted his life to the military. West has assembled a veritable rogue's gallery, including Timothy Hutton, Williams, and the brilliant, scene stealing Woods, to flesh out the list of colourful suspects.

| DOSE: |
|
insufflated |
Cocaine |
(powder / crystals) |
It started out innocently enough. An old high school buddy was visiting from out of the country, where he is attending college. We were both on winter break for a month and of course decided to do some partying.
We met up with another high school buddy, who had stay behind and was heavily into the local drug scene. After drinking beer out by the volcanoes, we decided to go back into town and see what else we could dig up to do.
We went by a dealer's house to see about picking up some dank weed, but upon entering his house we discovered another entirely different prize waiting for us.
I had not done cocaine in well over two years. My junior year in high school it came briefly into my life as a way to get homework done, but after losing a $100 bag of it I decided that I was ordained to quit.
I was drunk and stoned at the time and so had few inhibitions left to stop me from taking that first line of coke. It was like I had found a long lost friend. The euphoria hit me hard and almost instantly.
I remember I kept talking about how it had been far too long, far too long since I had brought cocaine into my life. I made arrangements to buy a 2-gram bag that evening, and after scrounging up money and dumping my bank account I had enough to go get it.
The first bag lasted me almost three weeks. Then I promised myself that when I ran out I would not do it anymore. But then the bag ran out and I was so sad I had to go hook up more. I finished that and swore I would quit.
Then the dreams started. I would have them almost every night. I was afraid to go to sleep because of them. They were always the same, hooking up with my friend and buying a large quantity of coke. The dreams ate at me until finally I gave in and bought over 6 grams of coke.
Once that was over I promised myself that I would quit. I did for a little while. The dreams didn't come but my mind kept demanding more coke. It would just all of a sudden decide it wanted it and would not let me do anything else till I had a bag in my hands and a line up my nose.
Every major and minor event in my life became another excuse to buy cocaine and do it in a binge of one night or sometimes I would make it out of the binge with a gram or two and it would last me several days to a week.
I would stay up all night snorting line after line. Then run out sometime in the afternoon of the next day and need more to appease the pain I was feeling for lack of sleep and way too much cocaine.
I started taking a special type of cocaine cut with a small quantity of methamphetamine, which made the euphoria last longer and reach greater heights.
Soon the paranoia, depression and hallucinations would start in on me during a binge. But I continue doing it to this day. Now, almost a year after I swore I would quit, I still find money for a couple bags every other week or every other day at times.
The mindset you get into in a binge is amazing. I remember sitting down and cussing my nostrils because one was so blocked up no coke could go up so I had to use the one that was bleeding. Instead of stopping the coke for a while to heal, I pushed it up the wounded nostril and ignored the intense sting it caused.
I still wake up in the mornings and swear off the 'demon powder' when my nostrils are burning so much that I can hardly stand it and have to pour water down my nose to cool it off, which of course does nothing.
Coke can be a great drug. It is a lot of fun and the quality of the high, while short, is so intense and pure that it drives you for more. I never have physical withdrawal symptoms, only intense mental drives that willpower can hardly fight, and often can not fight at all.
If it was unavailable or I had no more sources of money, quitting cocaine would be a relatively simple and fairly painless exercise. But one thing I can say for sure about the thralls of a binge, is that as long as you can get it, you will. Even if it leaves you broke and homeless.
In conclusion, I would not recommend cocaine to people with obsessive or addictive personalities. And those that do decide to try the drug, be careful you do not allow your mind to convince you of the safety of the drug, and that 'one more bag can not hurt.'

I am a qualified Pharmacologist, so I 'should' have known better.
 I used a graduated 1 ml syringe to measure into my drinks, which were occasionally alcoholic. This was usually at bedtime. I never had a problem, never exceeding 2-3 mls.
On a Sunday afternoon, I decided to read the newspaper and have a 'nap'. Instead of measuring the amount of 1,4 Butanediol into some grapefruit juice, I 'estimated' the amount and sloshed it in. BAD MOVE! An hour or so later, my kids noticed me asleep, but not breathing well, and they alerted my partner. I came round in a dream like state, but was unable to tell them what was happening, and I kept passing out. Next thing I remember were paramedics checking me out and coming round in Emergency resuscitation with drips in both arms.
They then started discussing doing a lumbar puncture, and possible brain surgery, and all this time I am trying to explain I was a qualified Pharmacologist, and I was not in any danger. In my confused state I could not remember the chemical I had taken, which was critical to managing my medical emergency.
Eventually, I recovered enough to explain what had happened, and apologise profusely for wasting valuable medical emergency resources.
I will not try this stuff again.
Anyone tempted, make sure you accurately measure the dose, and do not consume any more, as absorption times vary.
-------------------------------
June 2009 Addendum by author:
I would like to add a significant fact regarding my story which has since come to light.
I mention mixing the 1,4 Butanediol with grapefruit juice. There are many drug interactions with grapefruit juice, which inhibits an enzyme Cytochrome P 450 in the intestinal wall. This can cause much higher concentrations of a drug to get to the blood stream with dangerous results.
I am convinced this led to the OD reaction.

I have been humbled by DOI.
To set the scene, I have taken amongst the largest doses of LSD and mushrooms as anyone else I know and have never lost control, never had a +++ experience in the sense of 'The subject is totally engaged in the experience, for better or worse'. While in these hallucinogenic experience I have had obvious CEVs in the form of fractals, and OEVs like shifting dripping and oozing surfaces. While my mind state my have been reduced to outwardly idiotic, I have never felt uncomfortable, freaked out, or overpowered.
I took Friday off. I had some pharmaceutical grade DOI, 3.19mg I weighed out myself (on a related note, that DOI had been in its glass 100mg container for approximately 15 years at room temperature, and as you read, it probably hasn't lost any potency).
6:40am Placed dry powdered DOI under my tongue in the vague hope of sublingual absorption. After about 5 minutes I washed out the eppindorf which had held the DOI with water and swallowed it. The DOI didnt taste too bad, or cause any burning in the long term. I dozed in bed.
7:20am First alert? Maybe, maybe not.
8:10am My fiance goes off to work. I am alone. Another alert? Definitely
Between 8:20 and 9:20am I don't know what I'm doing. Am I partially asleep? am I having violent hallucinations? I am not sure. I am hiding under the covers of my bed. I feel I am too old (24 years old, lol) to be doing this kind of self destructive selfish behaviour, I feel very cold. Thankfully I have my 9-month old Labrador Dog to cuddle with. I feel physically uncomfortable, my feet are writhing. I am having bright, involved fractal closed eye visuals.
9:20am I sit upright in bed, still nude. I flick on the TV, it is some breakfast show rubbish. The sensory input, the massively swimming walls, the open eye fractal patterns and the physical unease are too much.  Painful Dry heaves. Once over, I feel much better and assume that that will be the last of the nausea, I hide under the covers again.
9:20 to 11ish. I am at the height of my experience, an easy +++. My CEVs are brilliant, clear and very interesting. But I am trying to fight them. I am wanting the experience to end. I roll from side to side under the blankets, in the pitch black and silence. I believe I may have had something very close to ego loss. In a closed eye hallucination, I saw 5 symmetrical boats being pounded on by waves, these 5 separate boats were all me, and I was all of them, I remember being concerned about 'us': I was thinking about myself in plural.
~11:00am I am freezing cold, and I do not want to seem like I have lay in bed all day while my fiance was at work. I get up, my coordination is poor, I stumble into the lounge.  I know a fair bit about neuroscience, and I think to myself 'This should be enough to set off my vomiting reflex'. The power of positive thinking perhaps, but my mouth fills with saliva and I am violently sick into the sink. Again, I feel much better. I eat a slice of pumpkin pie, realizing I have not eaten since last nights dinner.
This is a very strange experience. At times the visuals are overwhelming, but when I focus on mundane activities, eating a slice of pie, having a shower, going to the bathroom, I feel largely normal. Unlike LSD or mushroom experiences, my cognitive abilities feel completely intact.
I have a shower. It feel great, but I still can't get warm. I get back in bed and am quickly overtaken by CEVs again.
1:00pm My fiance comes back for lunch, I get up and sit with her. My open eye visuals have largely subsided, I do not feel like talking. I feel selfish and physically weak. She leaves, I smoke half a gram of strong cannabis, but I feel nothing from it. I have another shower and go bad to bed.
2:00-5:00pm I am still cold, I wish the hallucinations would go away. Both the CEVs and OEVs are a lot weaker, but some music videos still strongly set off the hallucinations. I get up at 5:00 to welcome my fiance home. I am still very quite and cold. I smoke another half gram of cannabis, but again feel nothing. Some of the muscle pains are getting worse and my mood is getting worse. I am having GI pains. I eat 2.5mg of Lorazepam, usually enough to get me very drowsy. Two hours later (7:00pm) I have another 2mg of lorazepam.
9:00pm Physical unease still strong. Most visuals have subsided, I am mentally still very on edge. I have a large glass of cognac 7.5mg of zopiclone and get in a hot bath. I play some Indian sitar music. For the first time I feel comfortable, warm, satisfied. The open eye visuals return, a pleasant play of the ripples over my body. It is worth noting that this cumulative dose of benzodiazepines would normally have me semi-conscious, I barely feel sleepy.
9:30pm - 10:30pm, I watched the last half of Indiana Jones and the last Crusade feeling largely normal apart from a sore throat and physical weakness. I close my eyes and fall asleep instantly.
11:00am I awake, and feel normal apart from the Lorazepam hang over.
What I learned from this experience:
1 Get dressed warmly before you take hallucinogens, and at least get dressed
2 It's too obvious, but no matter how experienced you think you are, get the set and setting right.
With respect to DOI: 3mg is not a middle dose, it is big.
I should have taken lorazepam as soon as I felt uncomfortable.
DOI is stable at room temperature in dry form for a long time.

We previously called that infra automation/orchestration
But Cloud is about others managing your infra, right? Why should we care?
Cloud brings big services’ portfolios you can compose to build your Internet-scale platform
And a plus: consistency across components
But apps still require a specific infrastructure configuration
Also applies to PaaS
Allows applying the same patterns than apps code

[gecode-users] Exists some other documentation than Doxygen style?
Michal Tuláček
michal at tulacek.eu
Thu Nov 27 13:01:52 CET 2008
Dears,
I am writing a bachelor thesis which is focused on comparing of
several constraint solvers. I compare the objective criterions - the
spent time and memory on solving of several benchmarks as well as
subjective criterions - the main focus is on easiness of learning of
usage.
Now I am in state, that Gecode looks interesting, it seems it offers
lots of possibilites how to describe a constraint problem but there is
a bit lack of documentation. I found only a doxygen generated
documentation but this is by my opinion best for "user who knows what
and how but doesnt know the exact spelling of function names or their
parameters" but mostly unuseful for new users who would need some
introduction. There are also some example problems, but the fact that
it is implementation of Example<> template, and the actual calls to
solver (initialization, etc.) is hidden somewhere in the parent
classes makes it more difficult for a newbie.
So my question is simple: Is there some tutorial to Gecode, even if
that would be for example only draft or something like that?
Thanks for answer, Michal Tulacek

autoproxy - Automatic HTTP proxy usage and authentication
This package attempts to automate the use of HTTP proxy servers in Tcl HTTP client code. It tries to initialize the web access settings from system standard locations and can be configured to negotiate authentication with the proxy if required.
On Unix the standard for identifying the local HTTP proxy server seems to be to use the environment variable http_proxy or ftp_proxy and no_proxy to list those domains to be excluded from proxying. On Windows we can retrieve the Internet Settings values from the registry to obtain pretty much the same information. With this information we can setup a suitable filter procedure for the Tcl http package and arrange for automatic use of the proxy.
There seem to be a number of ways that the http_proxy environment variable may be set up. Either a plain host:port or more commonly a URL and sometimes the URL may contain authentication parameters or these may be requested from the user or provided via http_proxy_user and http_proxy_pass. This package attempts to deal with all these schemes. It will do it's best to get the required parameters from the environment or registry and if it fails can be reconfigured.
Note This section only applies if TLS support is provided by the TLS package. It does not apply when autoproxy was configured to use some other package which can provide the same (i.e twapi), via the -tls_package configuration option.
This package uses the TLS package to handle the security for https urls and other socket connections.
Policy decisions like the set of protocols to support and what ciphers to use are not the responsibility of TLS, nor of this package itself however. Such decisions are the responsibility of whichever application is using the package, and are likely influenced by the set of servers the application will talk to as well.
For example, in light of the recent POODLE attack discovered by Google many servers will disable support for the SSLv3 protocol. To handle this change the applications using TLS must be patched, and not this package, nor TLS itself. Such a patch may be as simple as generally activating tls1 support, as shown in the example below.
package require tls tls::init -tls1 1 ;# forcibly activate support for the TLS1 protocol ... your own application code ...
Initialize the autoproxy package from system resources. Under unix this means we look for environment variables. Under windows we look for the same environment variables but also look at the registry settings used by Internet Explorer.
Retrieve individual package configuration options. See OPTIONS.
Configure the autoproxy package. Calling configure with no options will return a list of all option names and values. See OPTIONS.
Connect to a secure socket through a proxy. HTTP proxy servers permit the use of the CONNECT HTTP command to open a link through the proxy to the target machine. This function hides the details. For use with the http package see tls_socket.
The args list may contain any of the options supported by the specific TLS package that is in use but must end with the host and port as the last two items.
Connect to a target host throught a proxy. This uses the same CONNECT HTTP command as the tls_connect but does not promote the link security once the connection is established.
The args list may contain any of the options supported by the specific TLS package that is in use but must end with the host and port as the last two items.
Note that many proxy servers will permit CONNECT calls to a limited set of ports - typically only port 443 (the secure HTTP port).
This function is to be used to register a proxy-aware secure socket handler for the https protocol. It may only be used with the Tcl http package and should be registered using the http::register command (see the examples below). The job of actually creating the tunnelled connection is done by the tls_connect command and this may be used when not registering with the http package.
Basic is the simplest and most commonly use HTTP proxy authentication scheme. It is described in (1 section 11) and also in (2). It offers no privacy whatsoever and its use should be discouraged in favour of more secure alternatives like Digest. To perform Basic authentication the client base64 encodes the username and plaintext password separated by a colon. This encoded text is prefixed with the word "Basic" and a space.
The following options exists for this scheme:
package require autoproxy autoproxy::init autoproxy::configure -basic -username ME -password SEKRET set tok [http::geturl http://wiki.tcl.tk/] http::data $tok
package require http package require tls package require autoproxy autoproxy::init http::register https 443 autoproxy::tls_socket set tok [http::geturl https://www.example.com/]

Franks, J. et al. "HTTP Authentication: Basic and Digest Access Authentication", RFC 2617, June 1999 (http://www.rfc-editor.org/rfc/rfc2617.txt)
At this time only Basic authentication (1) (2) is supported. It is planned to add support for Digest (2) and NTLM in the future.

--- layout: page title: About Me description: A peak into who I am. background: '/img/bg-about.jpg' ---
My name is Annés but you can call me Nessie. A very special nickname given to me by my late mother.
This blog is dedicated to her. To her endless support and belief that I would one day find my passion in life.
I qualified as a chef and pastry chef in 2012. Although I loved working in the kitchen, my dream has always been to work online so that I could pursue my other passion: travelling the world.
A dream I thought was silly because I'm a chef and how can a chef work online?
One good thing that came out of this pandemic is that it forced me to re-evaluate my career options and that is when I discoverd that I could turn my love for developing and photographing recipes into a career.
Please follow me on my journey as I navigate this new chapter as an amateur food photographer.
Why did I choose the ketogenic lifestyle as my main focus?
I've been following a ketogenic lifestyle since 2016. It all started back in 2010, after leaving home. Studying and working took its toll on me and I started making very unhealthy choices.
I gained 35kg in a very short period of time, things like walking a few steps left me breathless and my doctor warned me that I was pre-diabetic.
Drastic changes had to be made. I explored various diets and tested them all out but the ketogenic lifestyle is the one that stuck and made me feel incredible. It's only once I cut carbs that I discoverd
my body doesn't digest them very well. Symptoms such as constant headaches and fatigue, bloating and other intestinal issues (issues I actually started struggling with in my teens but never even considered to be diet related) vanished.
Now I share my passion for this lifetsyle through my blog. All the recipes were either created or modified (from non-ketogenic recipes) by me.
Feel free to contact me for any collaborations

f_moma<-moma %>%

f_moma2<-count(f_moma,year_created,artist_gender)
ggplot(f_moma2,aes(x=year_created,y=n))+

The graph is a bar chart with the geom_smooth line showing the trend line.
The data refers to the moma dataset. In this graph, the final data frame is f_moma2(final moma). The quantitative variable is the count of number of paintings created.The qualitative variable is the year during which the paintings were created
The audience over here is someone who wants to see the paintings done by women over the years
This graph shows the count of number of paintings done by women across the years.
For year-gap on x-axis, read the number of paintings created during that period.
Major Highlights It seems that Women actually painted more paintings during the year 1960-2000. Also,the highest number of paintings(15) around 1985-1990.
Using scale_x_continuous and scale_y_continuous, the padding at the starting and ending of the x-axis has been removed. The color scheme used is in relation to the artist-gender(female). The trend line has been added to get the sense of overall increase/decrease using geom_smooth
This plot can be improved by including the Male gender to see how the Female’s performed wrt Male artists.
I formulated the question of what exactly I want: I have to see the diversity in the paintings created as per artist’s gender. First, I filtered the data-set on Male and Female. But due to large number of overlapping points , the stacked bar chart wasn’t the perfect fit. So, I decided to go with only one gender. Due to uncontinuity in the year column, the geom_line wasn’t the perfect fit, so decided to go with geom_col


Epicodus offers so many different courses,
we often get students unsure of what to take after they finish Introduction to Programming. If you're an Epicodus student or anybody wondering which language to learn, the first thing you need to decide is if you want to focus more on front-end or back-end development. Front-end developers spend their time making things look and work well, obsessing over layouts, navigation, colors, and design. If this type of work that appeals to you, your best bet is to take CSS and Design classes at Epicodus. If you're more interested in back-end development, you have several choices of languages: C#, Java, PHP, and Ruby are all offered at Epicodus. My best advice about how to choose is not to worry too much.Most modern programming languages have more similarities than differences, and Epicodus graduates often find themselves working in different languages than they studied in school.
Back-end programmers often switch languages as they change jobs, or even as they build different types of software at the same job. So don't stress too much about making the right choice! That said, each language has found a bit of a niche, and depending on your interests, you might be attracted to one over another.

Hearthstone Battlegrounds open beta has begun, with free packs for playing
by Andy ChalkAfter a week in early access release for BlizzCon attendees and pre-purchases, Blizzard's new autobattler Hearthstone Battlegrounds is now open to everyone. There are three free packs up for grabs in the form of a legendary quest which requires you to complete two full games of Battlegrounds, but given the interest in Hearthstone's first new mode in forever, I doubt that will feel too onerous.
The 15.6.2 patch that Blizzard said it was working on last week, to address the surprising number of Hearthstone bugs introduced by the release of Battlegrounds, is also live now too.
In the patch notes, community manager Kurt Ocher touched on some of the things Blizzard is working on for future Battlegrounds updates. New heroes and minions, including "a couple of very familiar faces," are coming in the next update, and expanded stats tracking, covering things like top five heroes by wins, most played heroes, and how many wins you've racked up, is also on the way. The leaderboard is being updated to offer more information about opposing players, and "the selling experience" is being improved to enable the sale of minions from your hand. Which should help if, like Tim, you have 'Boomer APM'.
Ocher emphasized that this is all "future-looking," and some of these features are a good way off: Changes to selling minions, for instance, aren't expected to arrive until early in 2020.
The 15.6.2 patch makes the expected bug fixes, as well as a handful of balance changes "that we identified based on our initial testing that didn’t quite make it in for release." Here's the full list of what's been changed:
Balance Changes:
Minions
- Mama Bear: Changed from 5/5 giving +5/+5 to 4/4 giving +4/+4
- Kangor’s Apprentice: Changed from 4/8 to 3/6
Hero Powers:
Infinite Toki
- Temporal Tavern: Changed from 1 cost to 2 and now reads “Refresh Bob’s Tavern. Add a minion from a higher Tavern Tier.”
King Mukla
- Bananarama: Changed to “Passive Hero Power: Whenever you buy a beast, add a Banana to your hand.”
Jaraxxus
- Bloodfury: Hero power changed from 3 cost to 2.
Game Fixes and Improvements:
- Squelch now works as intended + no longer causes crashes under certain circumstances
- Daily Quests can now be rerolled
- Hallow’s End Arena Daily Quest can now be completed
- A variety of Android crashes have been fixed
- Memory optimization for Battlegrounds for devices with less than 2GB of RAM
Hearthstone Battlegrounds is free to play for everyone with a Hearthstone account (which is also free), but players who have acquired card packs from the most recent Hearthstone expansion (through quests, gold purchases, bundles, events, or whatever) will also have access to bonus content: Ten packs will enable detailed stats about your Battleground performance in the Battlegrounds queue screen, 20 packs will let you choose from three heroes instead of two at the start of a match, and 30 packs will get you unique Battlegrounds emotes. If you haven't played Battlegrounds yet, you can get a crash course in what it's all about before you dive in with our handy "How to Play Hearthstone Battlegrounds" guide.


Switching Between Modes
To get out of whatever mode you are in (especially in case you don't know
or can't remember what mode you're in), just press the key twice, which
will return you to normal mode. The only mode in which you cannot do this is ex
mode, where instead you must type ":visual" in order to return to normal mode.
Once you have returned to normal mode, you will see the screen flash or head a
bell to let you know you have succeeded.
Switching to other modes:
- Normal mode to visual mode: type "V" (non case-sensitive) or "^V"
-
- Normal mode to select mode: select text with the mouse while the
'selectmode' option contains 'mouse' OR hold the shift key and use a non-
printable command to move the cursor while the 'selectmode' option
contains 'key'
- Normal mode to insert mode: type "I", "A", "O", "C", or "S" (non case-
sensitive)
- Normal mode to replace mode: type "R" or "gR"
- Normal mode to command-line mode: type ":", "/", "?", or "!"
- Normal mode to ex mode: type "Q"
- Visual mode to normal mode: type "+v", "v", or "CTRL+V"
- Visual mode to select mode: type "^G"
- Visual mode to insert mode: type "C" (non case-sensitive)
- Visual mode to replace mode: type "R" or "gR"
- Visual mode to command-line mode: type ":"
- Visual mode to ex mode: type "Q"
- Select mode to normal mode: type a non-printable command to move the
cursor (without holding the shift key)
- Select mode to visual mode: type "^O" or "^G"
- Select mode to insert mode: type a printable character, which will
insert the character and delete the selection
- Select mode to replace mode: type "R" or "gR"
- Select mode to command-line mode: type ":"
- Select mode to ex mode: type "Q"
- Insert mode to normal mode: type twice
- Insert mode to visual mode: type "^O" or "^G"

- Insert mode to replace mode: type the key
- Insert mode to command-line mode: type ":"
- Insert mode to ex mode: type "Q"
- Replace mode to normal mode: type twice
- Replace mode to visual mode: type "^O" or "^G"
- Replace mode to select mode: type "^G"
- Replace mode to insert mode: type the key
- Replace mode to command-line mode: type ":"
- Replace mode to ex mode: type "Q"
- Command-line mode to normal mode: type "CTRL+M" or "CTRL+N" (which
will execute the command) OR delete the entire line and then type
"CTRL+H" OR type twice (which will not execute the command)
- Command-line mode to visual mode: type "^O" or "^G"

As with other Spry widgets, you might want to either generate the code with Spry Data or populate the content with Spry Data. A common tooltip scenario is a variation of the master/detail pattern. For example, say you have a table that is the master region, and another table (the detail region) that updates in response to users clicking rows of the master. With the tooltip, you can make the detail region the tooltip, and make the row click the trigger. For a working sample, see the Using Spry Data with the Tooltip Widget page on Adobe Labs.
The key to working with Spry Data and the Tooltip widget, much like other widgets, is that due to the asynchronous nature of Spry Data, you have to control the regeneration of the widget when the data updates. The simplest way to do this is with observers. Observers regenerate the Tooltip widget every time the main region is updated. You use the onPostUpdate notification for this. The basic code is as follows:

{firstname} {lastname}

Phone:{phone}
 UserName:{username}
 ID:{@id}

Following is a breakdown of the code:
mainRegion is the ID of the Spry region we are listening to for data updates.
The trigger class is used to attach one tooltip to multiple elements.
The ID tooltip is the detail region.
The onmouseover event sets the current row in the data set, which updates the tooltip, depending on the selection.

Summary
Functions
Returns a subtree of tree indexed by point-index in a depth first traversal
computes the next row using the prev-row current-element and the other seq
If tree contains subtree at any level then this returns the smallest subtree of tree that contains but is not equal to the first instance of subtree. For example, contining-subtree([b [c [a]] [d [a]]], [a]]) => [c [a]]. Returns nil if tree does not contain subtree
Returns true if tree contains subtree at any level. Inefficient but functional implementation
Returns the number of paren pairs in tree
Returns the number of points in tree, where each atom and each pair of parentheses counts as a point
really make-list-if-not-seq, but close enough for here
Returns a copy of tree with the subtree formerly indexed by point_index (in a depth-first traversal) replaced by new_subtree
Returns a version of n that obeys limit parameters
Levenshtein Distance - http://en.wikipedia.org/wiki/Levenshtein_distance In information theory and computer science, the Levenshtein distance is a metric for measuring the amount of difference between two sequences. This is a functional implementation of the levenshtein edit distance with as little mutability as possible. Still maintains the O(n*m) guarantee
Like postwalk, but only for lists
Like postwalk-replace, but only for lists
Prints the provided thing and returns it
If thing is a literal, return its type -- otherwise return false
If a number, rounds float f to n decimal places
Returns the given list but with all instances of that (at any depth) replaced with this. Read as 'subst this for that in list'
