Ryan has baked you the most delicious cake you could ever imagine tasting, but before you eat it, you must figure out how to blow all the candles out.  The goal is to blow out all of the candles, ideally in the least number of moves.
When you blow out one candle in the circle, the two adjacent candles are extinguished as well. If you blow on a candle that has already been extinguished, it will relight. And if there is an extinguished candle next to the one you blow on, it also will relight.
To put it another way: When you blow on a candle, it—as well as the candles on either side—will change from lit to unlit, or vice versa.
If you need a hint, check out the source for this puzzle, which comes from Popular Mechanics Riddle of the Week #30.

@title Erlang Teaching Tool for Symbolic Evaluation
@copyright 2014 Gabriela Sampaio, Simon Thompson
@author Gabriela Sampaio
@author Simon Thompson
@doc The Erlang Teaching Tool for Symbolic Evaluation was created
with the aim of teaching how expressions are evaluated in Erlang.
== Contents ==
- {@section Introduction}
- {@section Download}
- {@section Symbolic Transformations}
- {@section How to use}
== Introduction ==
Symbolic evaluation is a form of static program execution in which symbolic expressions are used to represent arbitrary values of program variables and computations. This tool was created with the aim of teaching how expressions are evaluated in Erlang. The tool is able to evaluate not only arbitrary expressions, but also symbolic ones. The tool can be used by any Erlang programmer, but is more useful for beginners or teachers in the area. The idea is that the user can interact with the application by evaluating an expression step-by-step.
Symbolic transformations were created using Wrangler API. Wrangler is the refactoring tool for Erlang and it is user-extensible, i.e., users can create their own refactorings. With this possibility, some simplifications were built and are used in this project.
== Symbolic Transformations ==
Some symbolic transformations were created in the project. Expressions are simplified according to this set of transformations. To make the tool more organized and easier to understand, we divided the transformations into eight categories:
These simplifications are always used together. Thus, if the user types an expression that can be simplified by more than one type of evaluator, they are both used and each one simplifies a part of the expression.
== Download ==
The tool is distributed with the Wrangler tool. The user needs to download Wrangler from the Github website [https://github.com/RefactoringTools/Wrangler], and run the evaluator in the Erlang shell.
== How to use ==
To use the evaluator, the user needs to have Wrangler and Erlang installed. The application works in the Erlang shell. To start the evaluator, one of the functions start/1 and start/2 should be called. This function is described in the Evaluator module. After the evaluator is started, two inputs are needed:
- An expression: the user should write Erlang files containing definitions (modules, functions) and ideally, this expression should use these definitions. The expression can be a function call, an arithmetic calculation, a lists concatenation, etc.
- A number of steps: the user can choose a number of steps to be applied in the evaluation process. This number can be:
*A positive number: steps are applied "forward" in the evaluation process.
*A negative number: the respective number of steps are undone.
*"F" or "f" (for "full"): all steps are applied.
At the end of each iteration, the user has the chance to continue with the evaluation or start a new evaluation. If the user chooses to continue with the current evaluation, the only input requested is a new number of steps to be applied. Otherwise, the user chooses
a new expression to be evaluated and a new evaluation is started.

CIVET Workspaces¶
CIVET is part of a projected collection of open-source programs designed to work with very large sets of small text files: in the domain of contentious politics these are usually news articles but the issue of managing very large databases of small texts extends well beyond this application. For example, projects analyzing texts from legislative debates, legislation, campaign web sites and blogs all have much the same character when they are studied at a large scale.
In the CIVET system, files containing sets of individual stories are called “collections”: these are typically multiple related news stories—“texts”—from which one or more data records—“cases”—are coded. These are stored in a YAML format [1] which is a structured human-readable text file containing a number of data fields; the details of this are given in Appendix 2.
Sets of text collections are grouped into “workspaces” that also contain
an associated coding form and, optionally, other information such as
user-specified categories that will be used in automatic annotation. The
template file begins with the string “form.
” and uses the category
and template commands described in the chapter CIVET Coding Form Templates.
Workspaces are compressed (.zip
) directories (folders).
In the current configuration of the system, workspace files are uploaded to the system, annotated and/or coded, then downloaded when a session is completed: no data remain on the machine where the CIVET system is running. In a future version, we expect to have an option for persistent data that could be used on a secure server, as well as options for reading these files from a server.
The workspace will generally not be downloaded to the same place it
was originally: as a standard HTML security feature, the system does not
retain any information about where it obtained a file. Instead, it will
be downloaded to wherever your system downloads file: for example on the
Macintosh this is a folder named Downloads
. [2] If you wish to
replace the original workspace file, this will need to be done manually
or with a script operating locally.
There is some limited error checking as the workspace is processed. If errors are found you will get a screen similar to the figure below listing the errors, which must be corrected before the workspace can be used.
Like error messages in all programs, these are self-explanatory [3] though in general errors will occur either when you are processing a workspace for the first time or if you have manually edited it outside of the CIVET system: once a workspace has been successfully read by CIVET the program should not introduce any errors that would be caught at this point. [4]
The program is sensitive to file names:
- Any file ending with
.yml
is assumed to be a CIVET -formatted collections file - There should be one and only file beginning with the string
form.
: this specifies the coding form for the workspace - Any file beginning with
codes.
is assumed to be a category vocabulary list. In the file name, “codes.” must be followed by acategory
name then a period; the remainder of a “codes” file name can be anything, though typically it will end in.txt
. - Any file ending with
.ini
is assumed to be a configuration file [Version 1.0: Not yet implemented—see comments on setting globals in the “Preferences” chapter.]
Except for these restrictions, the directory can contain additional files of any kind: these will be preserved when the file is downloaded. A workspace file cannot contain subdirectories.
Additional notes on workspaces:
- So long as the YAML formatting is preserved—which should be fairly straightforward—the system is indifferent as to whether editing is done inside or outside of CIVET .
- If the
form
file is missing or contains errors, the system will display the errors it found, then return to the data selection page. - If you are manually editing the variable values in the
cases
section, any single quotes (’
) must be “escaped”; that is, replaced with\’
. This will be done automatically when cases are generated from inside the program. - The system currently translates UTF-8 encodings to ASCII [5] using the
Django function
encoding.smart_str()
. We expect to eventually convert the program to Python 3.x (at present it is Python 2.7) which is utf-8 “native” but it isn’t there yet.
Workspace Management¶
The Manage workspace
link on the home page will take you first to a
workspace selection page, and then to the page shown below. In Beta 0.9, only the
Export data in tab-delimited format/Use save-variable list in the template
is implemented: this will download any coded cases found in the
workspace. The remaining functions will eventually be implemented but in
the meantime these tasks can be done using a text editing program.
User-specified annotation vocabulary using category¶
The category
command is used to set up special categories of words
that will be color-coded and can be associated with text-extraction
fields. The annotation can either be done automatically or by manually
selecting the text and using the Style
pull-down menu in the
annotation editor.
category: category-name [color]comma-delimited-phrase/code-list or file-name
The category-name
must be unique and cannot be one of the standard
categories nament, num
or date
. The program currently
accommodates up to 99 categories. [6]
color
can be any of the 140 named HTML5 colors, [7] a six-digit
hexadecimal RGB color (e.g. 6A5ACD
corresponds to the named color
“SlateBlue”; the hex notation provides a presumably sufficient choice
of 16,777,216 colors), or a two-digit color from the CIVET
palette. [8] The palette, shown below, can be
accessed by entering the address[color]
is
empty—that is, []
—the system uses a color from the standard list
in the listed order.Automatic annotation/skip editing mode only:¶
When the program is running with Always apply annotation: True
and
Skip editing: True
, [9] categories can be further visually differentiated using
one or more of the following font specifications
- bold: bold face
- italic: italic
- under: underline
So for example [Green bold italic]
will display the category in an
italic bold font colored green.
Additional information on categories¶
1. Generally, matching of words and phrases is not case sensitive: in the example below, both “killed” and “Killed” will match. However, if the word in the category list is all uppercase—e.g. NATO, IRA, ISIS—it will only match all-uppercase strings: this should deal with most cases of acronyms, in particular US and IS. A word or phrase can only be in a a single category: putting one in multiple categories will not cause an error, but only the first category evaluated—generally this will occur in the order the categories were entered—will be marked. Words and phrases within a category are evaluated in the order they are listed—see the example in the chapter on annotation— which can be used to establish precedent when words or phrases overlap. At present the program does not allow partial matches, though a facility for this may be added in the future. [10]
2. The comma-delimited-phrase/code-list can have codes assigned to each of the phrases: these occur in brackets following the phrase and are added to the text during automated markup. The codes can be any character string. Either the phrase or the code or both can be specified in the output. If some of the phrases in the list have codes and others do not, the blank codes will be assigned a null (or, optionally, missing) string.
3. The vocabulary list can also be read from a file in the workspace. The
file name must begin with codes.category-name.
; the remainder of
the file name can be anything. [11] This be a text file with one phrase
per line and the code in brackets; a line beginning with # is treated as
a comment.
- As with texts, UTF-8 encodings are translated to ASCII using the
Django function
encoding.smart_str()
.
Example:
category:action [red italic]
killed [1], wounded [2], shot and killed [1], bombed [3], clashed [3]
category:people [Brown]
civilians, workers, authorities, troops, soldiers, rebels, people, group``
category:nationstate [Gold bold under]
codes.nationstate.txt
category:weapons [Olive]
codes.weapons.mnsa.weaponslist_150724.txt
Footnotes
| [1] | https://en.wikipedia.org/wiki/YAML |
| [2] | If you read the workspace from the same directory where it will eventually be downloaded, the behavior presumably depends on the operating system: in the case of OS-X both the downloaded file and the decompressed versions get a suffix added. E.g. if the original workspace folder is named “test123” with the compressed version “test123.zip”, the system assigns the downloaded version the name “test123 (1).zip” which decompressed to a folder named “test123 (1)”. We are leaving the task of insuring that the original file is not over-written to the operating system and whatever other utilities you might be using to manage workspaces. |
| [3] | Hahaha…just a little programmer joke… |
| [4] | For example, the error in the variable values string in the example screen
occurs because of the substring
'whois'='Case1-whois', which should actually be
'whois':'Case1-whois', but that ‘= ’ could only have been
introduced through external editing. |
| [5] | UTF-8 is an expanded UniCode character set that includes accented letters, “smart quotes” and many many more characters not found in the older ASCII (American Standard Code for Information Interchange) character set. UTF-8 is very widely used on the Web so if you have downloaded texts, there’s a pretty good change they contain at least some UTF-8 characters. |
| [6] | If you need more, this can be changed by allowing more digits in
the {:02d} format in the code
UserCategories[newcat].append('termst{:02d}'.format(len(UserCategories)))
in CIVET_template.make_category() |
| [7] | See http://www.w3schools.com/html/html colornames.asp |
| [8] | This palette was assembled in a very ad hoc manner, is not
color-blind-friendly, and we would be delighted to substitute
something better. The list is set as CIV_template.CatColorList |
| [9] | This is the configuration typically used when just coding the texts with automated annotation. We plan to retrofit this to the editor as well but adding it to the annotation was a simple hack, and adding it to the editor is a little more complicated. |
| [10] | If you want it now, delete the test if endx == idx+len(st): in
CIVET_utilities.do_string_markup() . |
| [11] | The period following the category-name is required!: the file name
codes.weapons_mnsa_list.txt would not be recognized as a valid
codes. file. Or rather it would be interpreted as applying to a
category weapons_mnsa_list , not the category weapons . |

The test started at 2017-01-01 10:00:00 and ended at 2017-01-01 12:00:00. A total of 1000 messages were produced and 1000 consumed. Of the produced messages 10 (1.00%) were delayed.
This is a reduced report without correctness details. To include correctness, be sure to use the id option when producing messages and include logs from both producers and consumers.

The flight times are measured in milliseconds between the produced and consumed times. Not the commit times - there may be a difference, in particular when batches are used. Percentiles are computed by picking the closest real value without any interpolation, so for tests with few messages per minute they will be formally correct but misleading.

Pass the Phone — Liar's Dice
Liar's Dice is a simple game about rolling dice and bluffing.
The goal of the game is to be the last one standing.
Each player starts with 5 dice.
At the start of each round, players roll their "hand" of dice.
Hands are hidden from other players.
Ones are "wild cards" and count as all other numbers (2-6)
Players take turns raising the bet, until a player "calls" or "spots" the bet.
When you raise the bet, you're claiming that there are at least that many of a certain type of die. For example, the bet "five threes" means that there are at least five dice that have a three (or one) on them, across all players' hands.
Bets can only be raised higher than the previous bet. The number of dice is more important than the value. Players cannot bet on ones.
If a player calls a bet, they are claiming that it's false. The player who is wrong (between the betting player and the calling player) loses a dice, and then a new round begins, and players roll their dice again.
If a player spots, they are claiming that there are exactly that many of that die. If they are wrong they lose a die, but if they are correct, every other player loses a die.
When you run out of dice, you lose, and the last one standing wins!

User Resource Limits
User resource limits dictate the amount of resources that can be
used
for a particular session. The resources that can be controled are:
- maximum size of core files
- maximum size of a process's data segment
- maximum size of files created
- maximum size that may be locked into memory
- maximum size of resident memory
- maximum number of file descriptors open at one time
- maximum size of the stack
- maximum amount of cpu time used
- maximum number of processes allowed
- maximum size of virtual memory available
It is important to note that these settings are per-session. This
means that they are only effective for the time that the user is logged in
(and for any processes that they run during that period). They are not global
settings. In other words, they are only active for the duration of the session
and the settings are not cumulative. For example, if you set the maximum
number of processes to 11, the user may only have 11 processes running per
session. They are not limited to 11 total processes on the machine as they
may initiate another session. Each of the settings are per process settings
during the session, with the exception of the maximum number of processes.
There are two types of limits that can be set for each property listed
above, a hard and soft limit. A hard limit cannot be changed by the user
once it is set. A soft limit, however, can be changed by the user but cannot
exceed the hard limit.
User resource limits are important to the security and stability of a
machine. If the machine that you wish to secure allows untrusted users to
run programs, then there is risk for abuse. Abuse is not limited to users
that have telnet shell access. If you allow users to run CGI scripts on
your web-server, these are also untrusted programs. Your system can be abused
just as easily from CGI scripts. The potential exists for a malicious user
to run a program that would eat up resources on the machine and make it unstable
or completely unusable for all the other users. This type of Denial of
Service (DoS) Attack is preventable with appropriate resource limits. It
is also possible that a well intentioned user who may make a simple programming
error which could cause their program to use unncessary amounts of system
resources. Both of these situations can be prevented by the proper implementation
of resource limits. This is necessary for the stability of any Linux machine.
Before we look at how to configure user resource limits, it is
important to also look at two sample types of attacks that use up
resources. These are simple example C programs that illustrate why
resource limits are so important. They are provided here for
educational purposes only, do not run them on a machine unless you have
explicit permission to do so. These are only two examples that I could
think of off the top of my head, there are probably many many more
types of resorce usage attacks. You can fend off the damage from these by proper resource limitations.
The following C program, as simple as it is, has the potential to
bring a machine to it's knees without proper user resource limits.
int main()
{
while(1)
fork();
return 0;
}
This program runs an infinite loop calling the fork() function.
Fork creates a child process that is virtually identical to the parent.
In other words, it creates another instance of the program . As you can
see, unrestrained this would create an incredible number of processes and
as a result the system will eventually lock up and become unstable.  However, this is not a
viable solution to the problem.
Here is where user resource limits come in. It is possible to limit the
number of processes that a user can launch in a single session. In other
words, the user who has telnetted in and runs this program can be limited
to the number of times the fork program can create child processes. While
their program will still raise the system's load, a proper limit on processes
will stop this from going out of control.
It is also possible that a malicious user may attack your system by using
all the available RAM. This can also happen by a rogue process that does
not properly manage its RAM. The following is an example of a program that's
only purpose is to allocate as much RAM as possible and never return it for
use:
int main()
{
char *p;
while(1)
p = (char *)malloc(sizeof(char) * 4096);
return 0;
}
Without any resource limits, this program will continue to allocate RAM
until there is no more RAM or swap space available. This may take a while
depending on the size of RAM and swap available, but it will eventually render
the system useless and require a reboot.
There are two main methods of implementing user resource limits on a
Linux machine. One involves using the properties of the login shell to
set these limits, the other uses PAM (Pluggable
Authentication Modules). Each have some advantages but in general
they accomplish the same goal: to limit the abuse that can occur on a
machine.
Most login shells provide a method of setting user resource limits. A login shell is a program such as bash
that provides an interface to the user when they log into the machine via
telnet. The major advantages to using this method of setting resource limits
is that all Linux machines have login shells such as bash. The primary disadvantage
is that the limits will only apply to users that have shell access to the
server and will only apply to programs ran from the shell.
For our purposes, we will focus on the bash login shell. These same principles can be applied to tcsh and other shells. Consult the documentation for your respective shell to determine how to set resource limits.
Bash has a built-in command called ulimit that enables the user to set resource limits. Burried deep in the bash manpage, it is documented as follows:
ulimit [-SHacdflmnpstuv [limit]]
Provides control over the resources available to the
shell and to processes started by it, on systems that
allow such control. The value of limit can be a number
in the unit specified for the resource, or the value
unlimited. The -H and -S options specify that the hard
or soft limit is set for the given resource. A hard
limit cannot be increased once it is set; a soft limit
may be increased up to the value of the hard limit. If
neither -H nor -S is specified, both the soft and hard
limits are set. If limit is omitted, the current value
of the soft limit of the resource is printed, unless
the -H option is given. When more than one resource is
specified, the limit name and unit are printed before
the value. Other options are interpreted as follows:
-a All current limits are reported
-c The maximum size of core files created
-d The maximum size of a process's data segment
-f The maximum size of files created by the shell
-l The maximum size that may be locked into memory
-m The maximum resident set size
-n The maximum number of open file descriptors (most
systems do not allow this value to be set)
-p The pipe size in 512-byte blocks (this may not be
set)
-s The maximum stack size
-t The maximum amount of cpu time in seconds
-u The maximum number of processes available to a
single user
-v The maximum amount of virtual memory available to
the shell
If limit is given, it is the new value of the specified
resource (the -a option is display only). If no option
is given, then -f is assumed. Values are in 1024-byte
increments, except for -t, which is in seconds, -p,
which is in units of 512-byte blocks, and -n and -u,
which are unscaled values. The return status is 0
unless an invalid option is encountered, a non-numeric
argument other than unlimited is supplied as limit, or
an error occurs while setting a new limit.
As you can see, it is fairly straighforward to use the
ulimit command. However, the question still remains as to
how we enforce these commands every time a user logs in to the shell.
Fortunately, the contents of /etc/profile are executed
every time bash is launched as a login shell. It is then
possible to place a series of ulimit commands to set a
hard limit on various resources.
If you have a system that uses PAM (Pluggable Authentication Modules) for authentication, you have another option for user resource limits. PAM comes with a resource limits module that is well documented here.
Authentication with PAM for various different applications are controled by the files located in /etc/pam.d . To set limits for users that login via telnet, you need to first edit /etc/pam.d/login and add the following line at the end of the series of lines that begin with session:
session required /lib/security/pam_limits.so
It is possible that this line may allready be there depending on what
distribution you are using, you should not add it again if it is allready
there.
The limits are then managed by editing the /etc/security/limits.conf file. See the documentation for the format of this file.
The major advantages of using PAM for resource limits is that different
users can easily be assigned different limits as well as users that are a
memeber of a group. PAM also allows you to limit the priority (see man nice
for more information) that the processes will be assigned and to determine
the maximum number of logins (to prevent the user from logging in many times
to attempt to avoid the process limitations).
So far we have covered the theory behind user limits and how they
can
be implemented. What documentation generally lacks are examples from
real-world scenarios. Hopefully the following examples will prove to
be useful.
We have a machine that many untrusted users are allowed access to. The
resources of the system need to be preserved and we choose the method of
using user limits imposed by the shell.
We want to limit all users except the user root. We only want
to allow a maximum of 40 open files per process, a maximum resident set size
of 16384 Kbytes (16MB), maximum data segment of 16384 Kbytes (16MB), a maximum
stack size of 8192 Kbytes (8MB), and a maximum core size of 16384 Kbytes
(16MB).
To accomplish this, we can place the following in the /etc/profile file.
if [ "$USER" != "root" ]; then
ulimit -n 40 -u 16 -m 16384 -d 16384 -s 8192 -c 16384
fi
Now when all users except root log in, they will have the resource limits
described above set for their session. The hard and soft limit will be set
to the same number for each of the types that appear in the preceeding ulimit
code. These limits will stay no matter what programs they run in that session.
You can verify that the limits are set by checking typing ulimit -a in the shell.
The actual values that you choose to limit will vary. The above limits
are being used successfully on a machine that has many untrusted users that
are allowed to run programs. It may be more appropriate to choose lower
resource limits (especially those regarding memory usage) depending on the
hardware you have. You can always raise the limits by editing the /etc/profile file if you find that the limits are too restrictive or not restrictive enough.
As we said before, PAM enables us to excercise a greater deal of flexibility
over who the resource limits apply to. In this example, we have users classified
into three groups: trusted, limtrst, and notrust. Users in the trusted
group are generally expected to be trusted users that don't run programs
that could use more resources than needed and so the resource limits on those
users do not need to be very strict. Users in the limtrst are generally trusted but could be running programs that might accidentally use too many resources. Users in the notrust
group are the least trusted, and will have very tight restrictions on what
resources they can use. We expect that if there was to be a resources attack,
it would come from the users in the notrust group
First, we have edited the /etc/pam.d/login and /etc/pam.d/sshd files and added the limits module as described here. This will make sure that both telnet and ssh connections are resource limited. We also may wish to do this for the /etc/pam.d/ftpd to limit ftpd resource usage as well.
Now we must decide what resourece limits to impose on each group. The
following are generally arbitrary numbers. The numbers you should use would
be based on the amount of memory you have. I have found it to be more of
a trial and error to determine what limits are too restrictive or need to
be more restrictive.
- Group trusted
- maximum size of core files: 10MB
- maximum size of a process's data segment: no limit
- maximum size of files created: no limit
- maximum size that may be locked into memory: 50MB
- maximum size of resident memory: 50MB
- maximum number of file descriptors open at one time: 1024
- maximum size of the stack: 50MB
- maximum amount of cpu time used: no limit
- maximum number of processes allowed: 35
- maximum size of virtual memory available: 100MB
- Group limtrst
- maximum size of core files: 10MB
- maximum size of a process's data segment: 30MB
- maximum size of files created: no limit
- maximum size that may be locked into memory: 30MB
- maximum size of resident memory: 30MB
- maximum number of file descriptors open at one time: 512
- maximum size of the stack: 30MB
- maximum amount of cpu time used: 600 seconds (10 minutes)
- maximum number of processes allowed: 25
- maximum size of virtual memory available: 50MB
- Group notrust
- maximum size of core files: 5MB
- maximum size of a process's data segment: 15MB
- maximum size of files created: 50MB
- maximum size that may be locked into memory: 15MB
- maximum size of resident memory: 15MB
- maximum number of file descriptors open at one time: 64
- maximum size of the stack: 15MB
- maximum amount of cpu time used: 120 seconds (2 minutes)
- maximum number of processes allowed: 15
- maximum size of virtual memory available: 25MB
To apply the preceeding resource limits, the following would go into the /etc/security/limits.conf file:
# limits for group "trusted"
@trusted hard core 10240
@trusted hard memlock 51200
@trusted hard rss 51200
@trusted hard nofile 1024
@trusted hard stack 51200
@trusted hard nproc 35
@trusted hard as 102400
# limits for group "limtrst"
@limtrst hard core 10240
@limtrst hard data 30720
@limtrst hard memlock 30720
@limtrst hard rss 30720
@limtrst hard nofile 512
@limtrst hard stack 30720
@limtrst hard cpu 10
@limtrst hard nproc 25
@limtrst hard as 51200
# limits for group "notrust"
@notrust hard core 5120
@notrust hard data 15360
@notrust hard fsize 51200
@notrust hard memlock 15360
@notrust hard rss 15360
@notrust hard nofile 64
@notrust hard stack 15360
@notrust hard cpu 2
@notrust hard nproc 15
@notrust hard as 25600
Now we can assign our users to one of those three groups depending
on what their level of trust is with regards to what they may run on
the machine that could use resources.
There are some limitations with the current implementation of user resource
limits. The largest is that you can only apply resource limits per session.
There is no way at the moment to place a quota on the number of resources
a certain user may use globally on the system.
At the moment, there is also no way to limit what is called from crontab (and possibly the same problem exists for at
as well). Crontab enables a user to launch a program at a specific time.
There is no way to apply resource limits to these launched programs in crontab's
present form.
CGI scripts also pose a problem. I mentioned before that even if you
disallow shell access but still allow users to run CGI scripts, there is
the same risk involved that a user could use too many system resources.
The best way to limit this is to run all cgi scripts through a program called
cgiwrap. You should specifically compile cgiwrap with the --with-rlimit-
settings to impose resource limits on all CGI scripts. There does not appear
to be a way to impose different limits on different user's CGI scripts, however.
The configuration of cgiwrap is beyond the scope of this document, but it
is highly recommended that you look into using it.
It is imperative that you employ some set of resource limits on any Linux
machines that you administer. Even if it is just a desktop machine and not
a server, user system resource limits can go a long way to avoiding crashes
because of runaway processes.
I have made every effort to explain this subject to the best of my knowledge.
However, there may be errors in the document. If you find one of these
errors, please let me know.

Right from the day we’re born until our last breath, water is our constant companion. Anything that paves way for a harmonious world holds highest importance in the world and needs to be educated to every human being so that it can be followed with discipline. When Guruji Mithreshiva realized the truth about water, he felt the need of the hour was to create the emotional connect between humans and the supreme living being "Water". We wish to turn this vision into reality by making the world understand the connectivity we have with water, thereby connecting people and nature through the Neerukku Nandri revolution. It’s high time that we re-establish our emotional bond with our beloved friend and the only way to reconnect is to be thankful to her for all that she has done in our life.
Gratitude is a feeling or attitude in acknowledgment of a benefit that one has received or will receive. Gratitude is not the same as feeling indebted to someone but, rather, feeling grateful is making a conscious choice to look for and acknowledge the good in any situation. In simple words, it is an art of celebrating and feeling content with everything we’ve received so far. From your body that has been supporting you all through your life to the smallest insect that nurtures the soil, it not only reminds you of all the things one should be grateful for in life but gives you back in folds of infinity. In ancient times, Rishis carried water (in a spouted pot called Kamandalam) as a medium to Bless or curse someone by giving instructions to her and sprinkling her on the person. Religiously, Christians used it as holy water in baptism processes, Hindus in the form of theertha, Muslims to cleanse themselves before every prayer session and so on. Our ancestors treated water with immense respect and were to a great extent, emotionally connected to her.
Every living being is made up of 70% of water, from head to toe. Every internal organ to the most minute cell functions because of water. Similar to how plants have life and feelings, it was proven that water is a living being that also has emotions. Water’s molecular structure is based on how it is being treated emotionally or how the surrounding is.  His extensive research findings have been compiled into his book which is a New York Best seller 'The Hidden Messages in Water'. The results of the experiments lead to shocking revelations to the world. When you expressed emotions of love and gratitude, the water crystal shined “Bright like a diamond”. When you expressed hatred and sadness the water crystal disinter-grated. That is what emotion and feeling can do to a living being. That is what emotions can do to Water.
Water is the source of all creations, there are endless reasons why we should show our gratitude towards water. We, living beings, have a stronger connection with water than we realize. Even before our birth, water carries us in our Mother’s Womb. From our birth to helping us sustain life, to our final ashes. Water supports, protects and carry us through the Journey of life. She is the creator of all beings, and the least we can do is show our heartfelt gratitude. Water listens to us just like we do. It sounds unbelievable, that’s why we’ve also taken the liberty of experimenting with the so-called life form.
We set up 3 jars with water and a handful of Rice.
Jar 1 - ‘Love’ jar where volunteers would talk to her in a loving and thankful manner.
Jar 2 - ‘Hate’ jar is where volunteers would use hurtful words to communicate with her.
Jar 3- ‘Ignore’ jar is a jar that no volunteer would bother to interact with.
Our results after 14 days showed the following results:
Jar 1 - The water is clean with a pleasant fragrance emitting out of the jar. The rice displayed a pure white color.
Jar 2 - The water produces an extremely unpleasant odour. The rice pellets formed black spots with mold formation.
Jar 3 - The water produced an aggravated formation of mold floating on water. The rice pellets turned extremely black.
The rice dissolved to form a colloidal solution.
From the above experiment, we can see that water responds to the way we communicate with her. She responds kindly when we speak to her in a sweet manner. She is disheartened when someone says harsh things against her. She is completely in a state of heartbreak and extreme disconnection with you when you ignore her. We are currently in ‘Jar-3’ condition. It’s time we establish contact and move towards ‘Jar-1’as soon as we can.
The simplest and effective way to thank water is to visualize everything that she has done for you since your birth. Simply saying thanks to water would not establish the sacred bond as compared to expressing your feelings from your heart. Feel the sense of gratitude in every moment during various actions- Drinking, Bathing, Washing, etc.
True gratitude is created only when one realizes the wonderful things water has done for us. One can show gratitude by being grateful for the 4 important aspects in life.
Firstly, show gratitude for every part of your body from every strand of hair, your heart, lungs, intestines all the way to your toes. Express your gratefulness in the form of love, the love similar to that of your mother’s love.
Secondly thank water for providing you with all forms of wealth, from the money you earn, the company you own to every object that you use.
Next, thank water for giving a great health to every member of your family and every individual who you have come across in each phase of your life. Next Finally thank all life forms every animal and every insect. Every resource from the sun to the moon, without which life on earth is impossible.
The above things in our life are all a matter of water, being grateful to the above is like giving utmost respect to Water. So let’s show our gratitude for this wonderful and selfless being.
Kallanai, Trichy was a drought-ridden location with patches of water scattered all over the place. River bed at the bottom was clearly visible to those who visited Kallanai. The native people lost hope that the place would be replenished with water but still supported us to see the slightest ray of hope.
Moments after the Aarthi celebration at the Neerukku Nandri movement, A sudden downpour of rain occurred. Four days after the Neerukku Nandri movement, The location where the stage was set, flows with a forceful gush of river water, thereby flourishing the ecosystem and assisting farmers in nearby villages with their agricultural harvests. People also realized the fact that we are completely dependent on water and we become extinct when water resources deplete. They have established an emotional connect with water which they had lost a long time ago. Native people have also considered ‘Neerukku Nandri’ to be a magical slogan that establishes a connect instantly.


Other than a few Steem meetups, I do not recall attending any crypto event like seminars, workshops or talks.  Did not have any idea where to look for, I proceeded to google the upcoming event in the city. Turns out the Eventbrite has things nicely organised in a list as follow:
Looking at the list, my unconscious reluctant mind keep asking questions like “Cryptocurrency masterclass? Sounds boring.” “What dahell is this? Is it even a topic?” “Do I really need to go to these events to learn or something new” “This information is everywhere on the Internet…”
Some are event teaching the topic like how to spot the 10X ICO. Okay, such claiming maybe a really efective clickbait in real life but is it the really beneficial to those who barely know what is blockchain technology?
Very not appropriate. I wouldn’t recommend my Mom to attend these events because she might be shilling the shitcoins by selling away every penny she has and probably sell away our house.
I’m not saying crypto event is bad but in fact I see more value in them if they were carried out by prominent figures like the famous Vitalik who frequently appears in Singapore. Or it could be project team which I’m interested in giving a talk in the town. That way I would greatly reduce the risk of running into some boring or even poisonous crypto seminars available all the time out there.
After all, internet feeds me with crypto information well enough. Why looking elsewhere?

Just wanted to let y’all know I had the S.E.T bar from @ironlionsoap before y’all did. This thing is amaaaaaaaaaazing. Glad that it’s the new formula in their line up. Amazing for my hair and beard and to get that funky klean. #teamklean #rideordie
Why, I love you too pork chop. Seasoned using @primalpalate barbecue rub. Baked in cast iron skillet at 275 until internal temp was 100 degrees. Thrown on piping hot grill for 4 min. Sweet potato was rubbed with coconut oil and @primalpalate meat and potato seasoning, wrapped in tin foil and placed on the grill for 40 min. Butter added after cutting. A side of green salad with balsamic vinegar was added to round out the dish. #butcherbox
One of the best decisions I made was to go gluten/grain free. It’s been almost a decade. It’s a decision i made when I was a surgical intern and i went through the normal “low carb flu” as my carb intake dropped. After my body acclimated I felt increased energy and better digestion, there was a decrease in sugar swings and an increase in mental clarity as well. I made the decision based on some research into non-celiac gluten sensitivity and reading that we as humans are not evolved to handle not properly prepared grains. It’s a decision I recommend time and again to everyone that asks.
The biggest change I am making recently is making sure I am getting enough exposure to early morning sunlight. Both on my skin and some non direct exposure into my eyes. This helps with the circadian rhythm and sleep wake cycle as well as vitamin D synthesis. Even when it is cold in DC, I try to expose myself to sunlight in the morning as long as I can tolerate the weather. People who can’t or are in colder climates may want to look into UV lamps and Ted light therapy to supplement.


Cryptography¶
TODO: do the other Encryption Types as well.
There is not a good writeup of how the cryptography in Bitwarden actually works. Bitwarden briefly covers it here . They also have a web page showing the crypto and @jcs wrote up the API: which covers the crypto, but glosses over some things.
I’ve written the client crypto code for Bitwarden in python and rust, so feel like it’s good to share what I’ve learned about how it all works.
We start with your email and password, these are the building blocks that everything is built from.
Your email address will be brought down to lowercase, and then will become the salt for everything. This makes sense, since you want salts to be unique, and email addresses are unique. If you want a tough salt, use a tough email address.
Every “Cipher” or login entry in Bitwarden is using symmetric encryption, specifically AES-256-CBC with PKCS#7 padding.
To decrypt something you need the encrypted text, which in Bitwarden comes in the form of a “CipherString” You also need the decryption Key and you need a mac key (to handle the HMAC part:
CipherStrings¶
- Cipher Strings include:
- Encryption type (so far 8 are setup)
- iv (the initialization vector to AES)
- ct (the encrypted text aka “cipher text”)
- mac (the Message authentication code to verify this message is not tampered with) - Optional.
An example CipherString:
2.6DmdNKlm3a+9k/5DFg+pTg==|7q1Arwz/ZfKEx+fksV3yo0HMQdypHJvyiix6hzgF3gY=|7lSXqjfq5rD3/3ofNZVpgv1ags696B2XXJryiGjDZvk=
Cipher Strings have 2 different seperators, a . and a | The period seperates the encryptType from the iv and rest of the string. the iv, ct and mac are seperated by a | symbol. the iv, ct and mac are base64 encoded via RFC3548.
Cipherstrings are what Bitwarden speaks across the API and what gets stored on disk.
So back to decryption. We get a CipherString but we still need a decryptionKey and a macKey.
Getting a decryptionKey and macKey¶
To get these, we have to go back to our email and password.
When you register and create an account, 2 “secret” things are created, a “master password hash” and a “key” what I call a protectedKey.
The Master Key is created by 5000 rounds of pbkdf2_hmac see bitwarden.crypto.makeKey for details, using your email as salt and your password as key.
This master key is never sent anywhere, it’s very important to keep it safe when it exists.
To create a Protected Key, we just randomly generate 64 bytes of data, with 16 bits of random iv and encrypt it with AES-CBC using the MasterKey, which we just talked about. Creation happens in the makeEncKey and then gets turned into a CipherString, which becomes the Protected Key.
The protectedKey is what we care about, it’s a combination of the decryptionKey and macKey that we need, stuffed inside of a CipherString. The protectedKey gets a unique encryption type (0) and does not get a MAC. Since it’s inside of a CipherString, we know it’s encrypted, so we have to decrypt it. To decrypt it we need the MasterKey.
The Master key can then be used as the key to decrypt the protectedKey see bitwarden.crypto.decryptEncryptionKey We decrypt using AES CBC, and we will get back 64 bytes of plaintext. the first half [0:32] will be the decryptionKey for CipherStrings of encryption type > 0. The second half (32:64) will be the macKey.
Decryption¶
Now we have our Master Key and macKey, we can decrypt. It’s also pretty straightforward. We decode the CipherString to get the ct, iv and mac. Then we compute a mac (iv + ct) using SHA256 HMAC and compare it to the mac we got from the CipherString. See macsEqual for comparison details.
Assuming our macs are equal, we can decrypt with AES-CBC to get padded plaintext. Then we use PKCS7 padding scheme to unpad (as described by Section 10.3, step 2, of RFC2315)
decryption is implemented in decrypt

These features are not finalized, their functionality, API, and existence may be subject to change.
Streaming the Firefly view
A Firefly server hosted via Flask can be rendered remotely and streamed
by visiting the localhost:xxxx/stream
URL.
For security reasons, this currently does not work if the host is not the current machine
(which defeats the purpose of streaming the view in the first place,
we’re working on getting around this limitation).
The FPS of the stream can be specified when starting the Flask server
see the documentation for firefly.server.startFireflyServer()
for details.
The stream quality will degrade to ensure the target FPS is achieved.
VR support
There is limited Google cardboard support for VR. If a Flask server is being hosted on a computer, then visit <local ip address>:xxxx/cardboard from a mobile phone connected on the same network and you should be able to look and move around.

There are a few elements to this recipe but every one of them would benefit from being prepared in advance so it's a great one for feeding a crowd.
Preheat the oven to 140C/275F/Gas 1 and butter a 30cm/12in x 20cm/8in cake tin.
For the parkin, put the soft brown sugar, butter, syrup and treacle into a small saucepan and melt over a gentle heat.
Put the oats, flour, ginger, nutmeg, mixed spice and a pinch of salt into a large bowl, then add the eggs and milk. Pour the melted butter and sugar mixture into the bowl and mix together with a whisk until combined.
Pour into the prepared tin and bake for 1¼ hours, or until firm in the centre.
Remove from the oven and leave in the tin to cool before turning out and cutting into squares. This is best kept kept in a tin for 2-3 days as it will become really sticky all the way through.
For the rhubarb, put the butter, sugar and five tablespoons of water in a large frying pan with the orange zest and rhubarb. Place over a gentle heat to poach for 4-5 minutes, or until just tender, then remove from the heat.
For the syrup, combine the golden syrup, cider and spices in a saucepan and bring to the boil. Reduce the heat and cook for 3-4 minutes, or until just thickened.
Serve the parkin in squares with a spoonful of rhubarb to one side and the syrup over the top. Finish with a scoop of ice cream.


Utah Jazz arena evacuated postgame due to suspicious package
by The Associated PressSALT LAKE CITY — Minutes after the end of an NBA game, the Utah Jazz’s home arena has been evacuated because of a suspicious package.
Most fans had already left the building Friday night when players, coaches and reporters were instructed to leave Vivint Smart Home Arena following Utah’s 113-109 victory over the Golden State Warriors.
Not long after both coaches finished answering postgame questions from the media, a spokesman for the Jazz told reporters to head outside because of a suspicious package. Outside the arena, reporters were instructed by security to leave the premises.
Players immediately headed for the exits to get in their cars, or the Warriors’ team bus. Jazz centre Rudy Gobert was still in his uniform as he left.

This sample demonstrates how to use the Driver Framework to write a user-mode filter driver. It demonstrates usage of I/O Target to send requests down the device stack and handling request completion. The building and installation instructions given here apply to Windows Server 2008.
The filter driver inverts bits on write and read requests to the device. Since the bits are inverted both on write and read, the application reads the same data it writes.
This sample filter driver is a minimal driver meant to demonstrate the usage of the User-Mode Driver Framework. It is not intended for use in a production environment.
See the usb\echo_driver directory for more information about the function driver associated with this sample.
|
Note: |
This sample requires installation of WinUsb runtime on Windows XP and would not work without that. Please check WinUsb documentation if WinUsb runtime is available for XP and how to install it. |
Start a build environment window as described under Building and Testing the Samples the UMDF Readme file.
Change to the directory containing the device source code, such as "CD CD c:\WINDDK\<build number>\src\usb\osrusbfx2\umdf\filter" (the WINDDK location and build number may vary.)
Run build -ceZ, or use the macro BLD. This command invokes the Microsoft make routines to build the components. If the build succeeds, you will find the driver, WudfOsrUsbFilter.dll in the binary output directory specified for the build environment. You can get the output path from the buildxxx.log file. If it fails you can find errors and warnings in the build error (.err) and warning (.wrn) log files respectively (buildfre_wlh_x86.err for example).
To test the sample you will need to setup your test system as described Building and Testing the Samples the UMDF Readme file.
You will need to build the function driver located in ..\echo_driver - this will create the WUDFOsrUsbDriver.dll binary mentioned below.
You will also need to copy the co-installer for the Kernel-Mode Driver Framework into the directory with your driver binary and INF (and include it in the catalog file if you're signing the driver package). This sample driver makes use of WinUSB, which is a KMDF based driver and so requires the KMDF co-installer for proper installation.
This sample's INF allows you to install both the filter driver (usb\filter) and the function driver (usb\echo_driver) on the OSR USB-FX2 Learning Kit board from OSR.
To install the USB-FX2 driver on Windows XP (SP2 and above), Vista and later operating systems:
1. Copy the filter binary (WudfOsrUsbFilter.dll) , driver binary (WudfOsrUsbDriver.dll) and the sample INF (WUDFOsrUsbFilterOnUmDriver.inf) file to a directory on your test machine (for example, c:\usbFilterSample.)
- Copy the UMDF coinstaller bianry WUDFUpdate_01009.dll from c:\winddk\<bld>\redist\wdf\<arch> directory of the WDK into the directory used above.
- Copy the KMDF coinstaller binary WdfCoinstaller01009.dll from the c:\winddk\<build_number>\redist\wdf\<arch> directory of the WDK into the directory used above. This is needed because this sample uses USB I/O targets which use WinUsb runtime which includes a KMDF driver.
4. Attach the OSR USB-FX2 device to your computer.
- At the "Welcome to the Found New Hardware Wizard" choose "No, not this time" and click Next.
- Select "Install from a list or specific location" and click Next.
- Select "Search for the best driver in these locations".
- Clear the "Search removable media (floppy, CD-ROM ...)" check box.
- Select the "Include this location in the search" check box.
- Enter the path to the files (for example: c:\usbFilterSample) under that check box and click Next.
- Click Finish at 'Completing the Found New Hardware Wizard.'
|
Note: |
Between steps 8 and 9 you may see a "Please select the best match for your hardware from the list below" page. This happens when there are multiple INFs which match your hardware. If this happens you should select an entry with "Microsoft UMDF OSR USB Sample Device With Filter on User-mode Driver" in the 'Description' column and the directory which holds the INF (for example c:\usbFilterSample) in the 'Location' column. If you have multiple versions of an INF in that directory, you may also need to check the 'Version' column to find the highest version number. Occasionally you may be told that no newer driver could be found for your device in this case. If that should happen use the alternate installation instructions below. |
Alternately you may use DevCon to install the filter driver for the OSR USB device:
- Copy the filter binary (WudfOsrUsbFilter.dll) , driver binary (WudfOsrUsbDriver.dll) and the sample INF (WUDFOsrUsbFilterOnUmDriver.inf) file to a directory on your test machine (for example, c:\usbFilterSample.)
- Copy the UMDF coinstaller bianry WUDFUpdate_01009.dll from c:\winddk\<bld>\redist\wdf\<arch> directory of the WDK into the directory used above.
- Copy the KMDF coinstaller binary WdfCoinstaller01009.dll from the c:\winddk\<build_number>\redist\wdf\<arch> directory of the WDK into the directory used above. This is needed because this sample uses USB I/O targets which use WinUsb runtime which includes a KMDF driver.
- Attach the OSR USB-FX2 device to your computer.
- At the "Welcome to the Found New Hardware Wizard" click Cancel.
- Change to the directory containing the inf and binaries (for example cd /d c:\usbFilterSample.)
- Run devcon.exe as follows:
devcon.exe update WUDFOsrUsbFilterOnUmDriver.inf "USB\Vid_0547&Pid_1002"
(note: the quotes are important because of the &)
DevCon can be found in the tools directory of your WDK enlistment (for example: d:\winddk\\tools\devcon\i386\devcon.exe.) To update the sample driver after making any changes:
- Increment the version number found in the INF. While this is not strictly necessary, it will help ensure PnP selects your new driver as a better match for the device.
- Copy the filter binary (WudfOsrUsbFilter.dll) , driver binary (WudfOsrUsbDriver.dll) and the sample INF (WUDFOsrUsbFilterOnUmDriver.inf) file to a directory on your test machine (for example, c:\usbFilterSample.)
- Follow instructions 4 and 5 above

MASQUE OF THE RED DEATH, THE (director: Roger Corman; screenwriters: from a story by Edgar Allan Poe/Charles Beaumont/Robert Wright Campbell; cinematographer: Nicolas Roeg; editor: Ann Chegwidden; cast: Vincent Price (Prince Prospero), Hazel Court (Juliana), Jane Asher (Francesca), Skip Martin (Hop Toad), David Weston (Gino), Patrick Magee (Alfredo), John Westbrook (Man in Red), Nigel Green (Ludovico), Paul Whitsun-Jones (Scarlatti); Runtime: 90; American International Pictures; 1964-USA/UK)
Reviewed by Dennis Schwartz
Roger Corman does another work by Edgar Allan Poe, in a film many critics considered his best from his Poe cycle. It's a visual treat, thanks to the lush camera work of Nicolas Roeg, but leaves a lot to be desired in its wooden story and characterizations.
Prince Prospero (Price) is a diabolical 12th century Italian prince, a worshipper of satan, who lives in a castle and amuses himself with orgiastic pleasures and having his victims die in depraved ways for his amusement, as he has his castle sycophants act as pet dogs for all his whims. They're happy to stay there in safety because the plague has ravaged the local town and countryside.
The film opens as a masked man, supposedly a holy man, dressed in red, meets an old lady in the woods, turns a white rose into a red rose, and tells the old lady to tell her townspeople "The day of deliverance is at hand."
Meanwhile Prospero has taken a beautiful village girl, Francesca (Asher), and tries to force her to choose between saving the life of her lover Gino (Weston) or her father (Green).  He tries to shake her faith in virtue and Christianity.
Prospero plans for a masked ball at midnight: in the meantime he brands the breasts of a beautiful Satanist woman, Julianna (Courts); Alfredo (Patrick Magee), one of his sycophant guests, is burned to death while clad as a gorilla by "Hop Frog" (Skip Martin), Prospero's demonic jester; and, a royal visitor, Scarlatti, is refused entrance to the castle and killed with an arrow by Prospero after begging for his life to be spared by offering him his wife.
The point of the film is Vincent Price's absolutely diabolical performance, no campy routine here. It's a performance showing pure evil and the reward is at the end watching him get his just desserts. Charles Beaumont's script was intelligent and subtle in making its case about devil-worshipping. But the film itself left me with a cold feeling.

Title
The story of the Hyena and the Lion (2nd version)
Collection
Summary
Not only in the astrological mythology, but also in the world of Bushman Fable, the lion naturally occupies a prominent position. One fine fable relates how the hyena revenged itself upon the lion, who had grudged it food, by inviting him to its own house, and then, while feeding him with soup, inverting the heated pot upon his head, and beating him to death underneath it. Of this fable we have two versions, the second being probably the better of the two (L II.–2. 361–368); whilst the earlier (LII.-1.257, 256 rev.-260 rev.) closes with the usual refrain respecting suitable marriages in animal life.

Aviation Turbine fuel is a mixture of a large number of different hydrocarbons. It is a specialized type of petroleum-based fuel used to power aircraft. It is generally of a higher quality than fuels used in less critical applications such as heating or road transport, and often contains additives to reduce the risk of icing or explosion due to high temperatures, amongst other properties. The range of their sizes (molecular weights or carbon numbers) is restricted by the requirements for the product, for example, the freezing point or smoke point. Kerosene-type jet fuel (including Jet A and Jet A-1) has a carbon number distribution between about 8 and 16 carbon numbers; wide-cut or naphtha-type jet fuel (including Jet B), between about 5 and 15 carbon numbers. The first jet fuels were based on kerosene or a gasoline-kerosene mix, and most jet fuels are still kerosene-based.

Kerosene-type jet fuel (including Jet A and Jet A-1) has a carbon number distribution between about 8 and 16 carbon numbers; wide-cut or naphtha-type jet fuel (including Jet B), between about 5 and 15 carbon numbers. The first jet fuels were based on kerosene or a gasoline-kerosene mix, and most jet fuels are still kerosene-based.
- After preliminary observations, set cooling water flow rate to an adequate value.
- Switch on the panel & purge chamber for 2-3 minutes.
- Reduce air flow rate to <100 kg/hr or LPG will blow off without ignition.
- Press ignition switch continuously as LPG flow is started, until a flame is established.
- Once LPG flame is established, introduce
- ATF KS 50 into the compression chamber.
- Can increase the air flow rate to >100 kg/hr & keep it constant at this value.
- Gradually decrease LPG flow rate to zero -combustion continues purely on ATF.
- Adjust fuel flow rate at the required value.
- Note the readings: air inlet temperature, water inlet & outlet temperatures, water flow rate, air flow rate, exhaust gas temperature. Also, observe the nature of the flame.
- Repeat above steps for different air-fuel ratios.
- Lean cut off point: Continuously increase the air-fuel ratio until the flame is blown off.
- Turn off the fuel supply.
- After the fuel in the supply line is used up, turn off the fuel valve.
- Again purge the chamber with air for 2 minutes.
- Switch off the burner & instrumentation panel.
- Turn off the cooling water after it is allowed to run for 5 more minutes.
Measurements
- Note the formulae for finding the airflow rate and fuel flow rates.
- Operate the unit on gaseous fuel according to operations manual. Change over to fuel after light up. Note your observation on flames with gaseous and liquid fuels.
- Carryout the experiment on the effect of air/fuel ratio on combustion, heat transfer and flue gas losses. Note the flame conditions.
- Plot the curves: a) Heat transfer to water-cooled walls vs. air/fuel ratio, b) waste gas heat loss vs. Air fuel ratio (for lean region).
- Carry out heat balance analyses by using theoretical flue gas analyses at air/fuel of maximum A/F ratio attained with steady operating conditions.

The range of application of the Hilton Combustion Demonstration Unit is wide,from simple but effective demonstrations for boiler operators to full-scale research and devleopment projects.The former are
self -evident from the nature of the Unit.It is to be expected that the main use of the Unit will be at undergraduate and post-graduate student level and this series of experiments are proposed for the main application,all having been
performed on a Unit installed at Portsmouth Polytechnic by students of these levels.
The majority of the experiments fall easily into two groups-Combustion with heat transfer and temperature measurement.It is under these headings that the experiments are presented.
Under all the experimental conditions laid down here,ignition is achieved strictly according to the Instructions and the water flow rate used throughout is commonly one which yields water outlet temperatures
in the range of 600 to 800C unless otherwise stated.On no account must the temperature rise above 850C.
Safety features built into the equipment include solenoid operated valves in both fuel lines,which are actuated by an ultra-violet flame sensor or by a relay on the water outlet temperature thermometer.


I am currently in a Master’s program in Computer Science at Northeastern University. Prior to enrolling in this program, I studied finance and marketing and interned at a private equity startup. While I enjoy analyzing businesses in different industries, I have realized that my strengths lie in solving business problems with a technical approach. As an analyst, I developed a variety of skills necessary for success in the field of Computer Science including analytical skills to understand and develop solutions to problems, and strong communication skills to exchange ideas and solutions to team members and clients.
In my MSCS program, I have programmed in Python, Java, and C. I also had experience in analyzing big data with R. I enjoy solving complicated problems with people from different backgrounds. As a strategic analyst, I also love to analyze different problems and create different ways to approach and solve difficult business problems. I believe that my experience as an analyst, in conjunction with the skills I am developing in my master's program, will make me a fit for roles in software engineering, research and data science. My current goal is to gain practical experience through co-op/internships and knowledge in machine learning and artificial intelligence as I progress through the master’s in computer science program.
