NAME
unzipsfx - self-extracting stub for prepending to ZIP archivesSYNOPSIS
<name of unzipsfx+archive combo> [-cfptuz[ajnoqsCLV$]] [file(s) ... [-x xfile(s) ...]]DESCRIPTION
unzipsfx is a modified version of unzip(1L) designed to be prepended to existing ZIP archives in order to form self-extracting archives. Instead of taking its first non-flag argument to be the zipfile(s) to be extracted, unzipsfx seeks itself under the name by which it was invoked and tests or extracts the contents of the appended archive. Because the executable stub adds bulk to the archive (the whole purpose of which is to be as small as possible), a number of the less-vital capabilities in regular unzip have been removed. Among these are the usage (or help) screen, the listing and diagnostic functions (-l and -v), the ability to decompress older compression formats (the ``reduce,'' ``shrink'' and ``implode'' methods). The ability to extract to a directory other than the current one can be selected as a compile-time option, which is now enabled by default since UnZipSFX version 5.5. Similarly, decryption is supported as a compile-time option but should be avoided unless the attached archive contains encrypted files. Starting with release 5.5, another compile-time option adds a simple ``run command after extraction'' feature. This feature is currently incompatible with the ``extract to different directory'' feature and remains disabled by default.Note that self-extracting archives made with unzipsfx are no more (or less) portable across different operating systems than is the unzip executable itself. In general a self-extracting archive made on a particular Unix system, for example, will only self-extract under the same flavor of Unix. Regular unzip may still be used to extract the embedded archive as with any normal zipfile, although it will generate a harmless warning about extra bytes at the beginning of the zipfile. Despite this, however, the self-extracting archive is technically not a valid ZIP archive, and PKUNZIP may be unable to test or extract it. This limitation is due to the simplistic manner in which the archive is created; the internal directory structure is not updated to reflect the extra bytes prepended to the original zipfile.
ARGUMENTS
- [file(s)]
-
An optional list of archive members to be processed.
Regular expressions (wildcards) similar to those in Unix egrep(1)
may be used to match multiple members. These wildcards may contain:
-
- *
- matches a sequence of 0 or more characters
- ?
- matches exactly 1 character
- [...]
- matches any single character found inside the brackets; ranges are specified by a beginning character, a hyphen, and an ending character. If an exclamation point or a caret (`!' or `^') follows the left bracket, then the range of characters within the brackets is complemented (that is, anything except the characters inside the brackets is considered a match).
-
- (Be sure to quote any character that might otherwise be interpreted or modified by the operating system, particularly under Unix and VMS.)
- [-x xfile(s)]
- An optional list of archive members to be excluded from processing. Since wildcard characters match directory separators (`/'), this option may be used to exclude any files that are in subdirectories. For example, ``foosfx *.[ch] -x */*'' would extract all C source files in the main directory, but none in any subdirectories. Without the -x option, all C source files in all directories within the zipfile would be extracted.
If unzipsfx is compiled with SFX_EXDIR defined, the following option is also enabled:
- [-d exdir]
- An optional directory to which to extract files. By default, all files and subdirectories are recreated in the current directory; the -d option allows extraction in an arbitrary directory (always assuming one has permission to write to the directory). The option and directory may be concatenated without any white space between them, but note that this may cause normal shell behavior to be suppressed. In particular, ``-d ~'' (tilde) is expanded by Unix C shells into the name of the user's home directory, but ``-d~'' is treated as a literal subdirectory ``~'' of the current directory.
OPTIONS
unzipsfx supports the following unzip(1L) options: -c and -p (extract to standard output/screen), -f and -u (freshen and update existing files upon extraction), -t (test archive) and -z (print archive comment). All normal listing options (-l, -v and -Z) have been removed, but the testing option (-t) may be used as a ``poor man's'' listing. Alternatively, those creating self-extracting archives may wish to include a short listing in the zipfile comment.See unzip(1L) for a more complete description of these options.
MODIFIERS
unzipsfx currently supports all unzip(1L) modifiers: -a (convert text files), -n (never overwrite), -o (overwrite without prompting), -q (operate quietly), -C (match names case-insensitively), -L (convert uppercase-OS names to lowercase), -j (junk paths) and -V (retain version numbers); plus the following operating-system specific options: -X (restore VMS owner/protection info), -s (convert spaces in filenames to underscores [DOS, OS/2, NT]) and -$ (restore volume label [DOS, OS/2, NT, Amiga]).(Support for regular ASCII text-conversion may be removed in future versions, since it is simple enough for the archive's creator to ensure that text files have the appropriate format for the local OS. EBCDIC conversion will of course continue to be supported since the zipfile format implies ASCII storage of text files.)
See unzip(1L) for a more complete description of these modifiers.
ENVIRONMENT OPTIONS
unzipsfx uses the same environment variables as unzip(1L) does, although this is likely to be an issue only for the person creating and testing the self-extracting archive. See unzip(1L) for details.DECRYPTION
Decryption is supported exactly as in unzip(1L); that is, interactively with a non-echoing prompt for the password(s). See unzip(1L) for details. Once again, note that if the archive has no encrypted files there is no reason to use a version of unzipsfx with decryption support; that only adds to the size of the archive.AUTORUN COMMAND
When unzipsfx was compiled with CHEAP_SFX_AUTORUN defined, a simple ``command autorun'' feature is supported. You may enter a command into the Zip archive comment, using the following format:
$AUTORUN$>[command line string]
When unzipsfx recognizes the ``$AUTORUN$>'' token at the beginning of the Zip archive comment, the remainder of the first line of the comment (until the first newline character) is passed as a shell command to the operating system using the C rtl ``system'' function. Before executing the command, unzipsfx displays the command on the console and prompts the user for confirmation. When the user has switched off prompting by specifying the -q option, autorun commands are never executed.
In case the archive comment contains additional lines of text, the remainder of the archive comment following the first line is displayed normally, unless quiet operation was requested by supplying a -q option.
EXAMPLES
To create a self-extracting archive letters from a regular zipfile letters.zip and change the new archive's permissions to be world-executable under Unix:
cat unzipsfx letters.zip > letters chmod 755 letters zip -A letters
To create the same archive under MS-DOS, OS/2 or NT (note the use of the /b [binary] option to the copy command):
copy /b unzipsfx.exe+letters.zip letters.exe zip -A letters.exe
Under VMS:
copy unzipsfx.exe,letters.zip letters.exe letters == "$currentdisk:[currentdir]letters.exe" zip -A letters.exe
(The VMS append command may also be used. The second command installs the new program as a ``foreign command'' capable of taking arguments. The third line assumes that Zip is already installed as a foreign command.) Under AmigaDOS:
MakeSFX letters letters.zip UnZipSFX
(MakeSFX is included with the UnZip source distribution and with Amiga binary distributions. ``zip -A'' doesn't work on Amiga self-extracting archives.) To test (or list) the newly created self-extracting archive:
letters -t
To test letters quietly, printing only a summary message indicating whether the archive is OK or not:
letters -tqq
To extract the complete contents into the current directory, recreating all files and subdirectories as necessary:
letters
To extract all *.txt files (in Unix quote the `*'):
letters *.txt
To extract everything except the *.txt files:
letters -x *.txt
To extract only the README file to standard output (the screen):
letters -c README
To print only the zipfile comment:
letters -z
LIMITATIONS
The principle and fundamental limitation of unzipsfx is that it is not portable across architectures or operating systems, and therefore neither are the resulting archives. For some architectures there is limited portability, however (e.g., between some flavors of Intel-based Unix).Another problem with the current implementation is that any archive with ``junk'' prepended to the beginning technically is no longer a zipfile (unless zip(1) is used to adjust the zipfile offsets appropriately, as noted above). unzip(1) takes note of the prepended bytes and ignores them since some file-transfer protocols, notably MacBinary, are also known to prepend junk. But PKWARE's archiver suite may not be able to deal with the modified archive unless its offsets have been adjusted.
unzipsfx has no knowledge of the user's PATH, so in general an archive must either be in the current directory when it is invoked, or else a full or relative path must be given. If a user attempts to extract the archive from a directory in the PATH other than the current one, unzipsfx will print a warning to the effect, ``can't find myself.'' This is always true under Unix and may be true in some cases under MS-DOS, depending on the compiler used (Microsoft C fully qualifies the program name, but other compilers may not). Under OS/2 and NT there are operating-system calls available that provide the full path name, so the archive may be invoked from anywhere in the user's path. The situation is not known for AmigaDOS, Atari TOS, MacOS, etc.
As noted above, a number of the normal unzip(1L) functions have been removed in order to make unzipsfx smaller: usage and diagnostic info, listing functions and extraction to other directories. Also, only stored and deflated files are supported. The latter limitation is mainly relevant to those who create SFX archives, however.
VMS users must know how to set up self-extracting archives as foreign commands in order to use any of unzipsfx's options. This is not necessary for simple extraction, but the command to do so then becomes, e.g., ``run letters'' (to continue the examples given above).
unzipsfx on the Amiga requires the use of a special program, MakeSFX, in order to create working self-extracting archives; simple concatenation does not work. (For technically oriented users, the attached archive is defined as a ``debug hunk.'') There may be compatibility problems between the ROM levels of older Amigas and newer ones.
All current bugs in unzip(1L) exist in unzipsfx as well.
DIAGNOSTICS
unzipsfx's exit status (error level) is identical to that of unzip(1L); see the corresponding man page.SEE ALSO

The goal of funneljoin is to make it easy to analyze behavior funnels. For example, maybe you’re interested in finding the people who visit a page and then register. Or you want all the times people click on an item and add it to their cart within 2 days. You can do this with funneljoin’s after_join()
function. The arguments are:
x
: a dataset with the first set of behaviors.y
: a dataset with the second set of behaviors.by_time
: a character vector to specify the time columns in x and y. This would typically be a datetime or a date column. These columns are used to filter for time y being after time x.by_user
: a character vector to specify the user or identity columns in x and y.mode
: the method used to join: “inner”, “full”, “anti”, “semi”, “right”, “left”. You can also use after_mode_join
instead (e.g. after_inner_join
instead of after_join(..., mode = "inner")
)type
: the type of funnel used to distinguish between event pairs, such as “first-first”, “last-first”, “any-firstafter”. See types of funnels for details.max_gap
(optional): the maximum gap between events. Can be a integer representing the number of seconds between events or a difftime object.gap_col
(optional): whether to return a numeric column, .gap
, with the time difference in seconds between the events. Defaults to FALSE
.As funneljoin uses dplyr, it can also work with remote tables, but has only been tried on postgres. Some of the functionality, especially the gap joins, use SQL code that may not work with different versions.
You can install the development version from GitHub with:
# install.packages("devtools")
devtools::install_github("robinsones/funneljoin")
type
can be any combination of first
, last
, any
, and lastbefore
with first
, last
, any
, and firstafter
. Some common ones you may use include:

7, "2018-07-07"
) %>%
mutate(timestamp = as.Date(timestamp))
Let’s say we wanted to get only the first time people landed and registered. We would use a first-first inner
join:
landed %>%
after_inner_join(registered,
by_user = "user_id",
by_time = "timestamp",
type = "first-first")
#> # A tibble: 4 x 3
#> user_id timestamp.x timestamp.y
#> <dbl> <date> <date>
#> 1 1 2018-07-01 2018-07-02
#> 2 3 2018-07-02 2018-07-02
#> 3 6 2018-07-07 2018-07-10
#> 4 5 2018-07-10 2018-07-11
If your time and user columns have different names, you can work with that too:
landed <- landed %>%
rename(landed_at = timestamp,
user_id_x = user_id)
registered <- registered %>%
rename(registered_at = timestamp,
user_id_y = user_id)
landed %>%
after_inner_join(registered,
by_user = c("user_id_x" = "user_id_y"),
by_time = c("landed_at" = "registered_at"),
type = "first-first")
#> # A tibble: 4 x 3
#> user_id_x landed_at registered_at
#> <dbl> <date> <date>
#> 1 1 2018-07-01 2018-07-02
#> 2 3 2018-07-02 2018-07-02
#> 3 6 2018-07-07 2018-07-10
#> 4 5 2018-07-10 2018-07-11
Funneljoin also contains two functions to summarize funnels: summarize_conversions()
and summarize_prop_tests()
- see the vignette for details.
If you find any bugs or have a feature request or question, please create an issue. If you’d like to add a feature, tests, or other functionality, please also make an issue first and let’s discuss!


Installation¶
This section describes the necessary steps for installing PyPDEVS.
Dependencies¶
The following dependencies are mandatory:
- python 2.7
For parallel and distributed simulation, the following additional dependencies are required:
- MPICH3 with socket device
- mpi4py
Installation instructions are given for these two dependencies further in this section.
Realtime simulation using the Tk backend, obviously requires Tk.
PyPDEVS Installation¶
Execute the following command in the ‘src’ folder:
python setup.py install --user
Afterwards, PyPDEVS should be installed. This can easily be checked with the command:
python -c "import pypdevs"
If this returns without errors, PyPDEVS is sucessfully installed.
Parallel and distributed simulation with mpi4py¶
Note
An installation script for mpi4py and MPICH3 is provided in install_mpi4py.sh
.
First of all, an MPI middleware has to be installed, for which I recommend MPICH3. Due to some non-standard configuration options, it is required to install MPICH manually instead of using the one from the repositories.
You can use either the official installation guide, or follow the steps below. Just make sure that the correct configuration options are used.
The following commands should work on most systems, just replace the ‘/home/you’ part with a location of your choosing:
mkdir mpich-build
mkdir mpich
base=`pwd`
cd mpich-build
wget http://www.mpich.org/static/downloads/3.1.2/mpich-3.1.2.tar.gz
tar -xvzf mpich-3.1.2.tar.gz
cd mpich-3.1.2
./configure --prefix=$base/mpich --with-device=ch3:sock --disable-fortran
make
make install
export PATH=$base/mpich/bin:$PATH
cd ../..
You will probably want to put this final export of PATH to your .bashrc file, to make sure that mpi is found in new terminals too. After that, make sure that the following command does not cause any errors and simply prints your hostname 4 times:
mpirun -np 4 hostname
Now you just need to install mpi4py, which is easy if you have MPICH installed correctly:
mkdir mpi4py
cd mpi4py
wget https://pypi.python.org/packages/source/m/mpi4py/mpi4py-1.3.1.tar.gz
tar -xvzf mpi4py-1.3.1.tar.gz
cd mpi4py-1.3.1
python setup.py build --mpicc=../../mpich/bin/mpicc
python setup.py install --user
cd ../..
Testing whether or not everything works can be done by making sure that the following command prints ‘4’ four times:
mpirun -np 4 python -c "from mpi4py import MPI; print(MPI.COMM_WORLD.Get_size())"


There are two user interfaces to help you learn to build valid ChemIDplus API Search URLs: this application and the Swagger UI. We expect this ChemIDplus API Search application will be more useful for most users, especially for building multi-expression searches.
Click the
button above to read how to create and edit both single- and multi-expression searches.After entering expression(s) and clicking the
button, the browser navigates to the HTML view of the results. To investigate the API Search URLs and JSON/XML/TSV results for any search, click the button on the top right and select "API". You will then see two API Search URL links and two JSON results. The top section is for Totals; the URL includes data=totals and thus only returns the count of matching substances. Then the next section is for all the per-substance data types.The default data returned is the summary of each matching substance. You can use the
button to return other information for each matching substance. You can set your preference for the default Data under .The default result format is JSON. Using the
button, you may instead request XML or TSV. TSV is similar to CSV but uses the tab character as the delimiter; which means the output can be read by your favorite spreadsheet program. You can set your preferred format as default under .The results based on the selected parameters are listed below those two choices.
An alternative to using this ChemIDplus API Search is the Swagger UI. This includes more machine-readable information and is available at https://chem.nlm.nih.gov/api/swagger-ui.html. However, it does not include details about how to generate valid multi-expression searches.

Perform cubic (or Hermite) spline interpolation of given data points, returning either a list of points obtained by the interpolation or a function performing the interpolation.

Handling of tied |
The inputs can contain missing values which are deleted, so at least
one complete (x, y)
pair is required.
If method = "fmm"
, the spline used is that of Forsythe, Malcolm
and Moler (an exact cubic is fitted through the four points at each
end of the data, and this is used to determine the end conditions).
Natural splines are used when method = "natural"
, and periodic
splines when method = "periodic"
.
The method "monoH.FC"
computes a monotone Hermite spline
according to the method of Fritsch and Carlson. It does so by
determining slopes such that the Hermite spline, determined by
(x[i],y[i],m[i]), is monotone (increasing or
decreasing) iff the data are.
Method "hyman"
computes a monotone cubic spline using
Hyman filtering of an method = "fmm"
fit for strictly monotonic
inputs.
These interpolation splines can also be used for extrapolation, that is
prediction at points outside the range of x
. Extrapolation
makes little sense for method = "fmm"
; for natural splines it
is linear using the slope of the interpolating curve at the nearest
data point.
spline
returns a list containing components x
and
y
which give the ordinates where interpolation took place and
the interpolated values.
splinefun
returns a function with formal arguments x
and
deriv
, the latter defaulting to zero. This function
can be used to evaluate the interpolating cubic spline
(deriv
= 0), or its derivatives (deriv
= 1, 2, 3) at the
points x
, where the spline function interpolates the data
points originally specified. It uses data stored in its environment
when it was created, the details of which are subject to change.
The value returned by splinefun
contains references to the code
in the current version of R: it is not intended to be saved and
loaded into a different R session. This is safer in R >= 3.0.0.

Welcome to the CSCAR treatment assignment system
Background: The sequential treatment assignment system is intended to assist researchers who are conducting trials in which subjects are assigned sequentially to treatment groups. It aims to provide treatment assignments that are balanced across the levels of one or more pre-treatment covariates. Sequential assignment is useful whenever a complete list of all research subjects is not available at the beginning of a trial. It is especially effective when a study will enroll a small or moderate number of subjects.
Methodology: This system implements an approach to treatment assignment using minimization that was described in Pocock and Simon (Biometrics 31, 1975). The minimization approach reduces covariate imbalances by utilizing non-uniform assignment probabilities for the different treatment groups, in order to reduce the level of imbalance following each round of treatment assignment. Although the probabilities are not uniform, the treatment assignments are still random, which reduces the risk that a user can bias the results of the trial by selectively enrolling patients.
Security: This system identifies users through their
Google account id. Users must be signed into their Google
account whenever using the system. This system runs on Google
AppEngine and the data are stored on Google's servers. You will
be given the option to store either complete data or aggregated
data for the subjects in your study. In the latter case, only
the frequency distributions of each covariate within each
treatment group are retained by the system.

+XP takes the base leaderboard system and adds a simple, experience-based "leveling" system on top of it.
Now, every recorded cup of coffee grants the user experience points, which earn the user levels, achievements, etc.
This is still a major work-in-progress!
For each recorded cup of coffee, the following experience is calculated:
Starting experience: each cup starts with a worth of 100 experience points.
First cup of the day: the first cup drunk every day earns an extra 10 experience points.
Day Streak Bonus: for every day in row before the recorded cup that the user drank coffee, the user gains a bonus 5 experience points; the maximum bonus points is 35 (7 days). Note: this bonus only applies to the first cup recorded each day.
Late penalty: cups that are submitted late (via the -y
and
--yesterday
parameters) are only worth 25 experience points, and
do not receieve further bonuses. However, they do still count for the Day Streak Bonus
for future cup entries.
This is the experience calculated for the first cup of the day, with a 3 day streak.
Starting score: 100 First cup bonus: 10 3 day streak bonus: 15 ---- Total: 125
As the user gains experience points, he will level up. There are 20 levels, but after the 20th level the user can level up once more to gain a Prestige Level. When a user gains a Prestige Level, his current level resets to 1, and the leveling continues.
A user's experience points a cumulative across levels and prestige, meaning it is possible to see not only what a user's current prestige and level are, but also the exact number of experience points they have gained over time.
Now, every recorded cup of coffee grants the user experience points, which earn the user levels, achievements, etc.
Experience Table
| Level | XP Needed |
|---|---|
| {% if loop.index != 20 %}{{loop.index+1}}{% else %}Prestige{% endif %} | {{row}} |
The basic experience point gain and leveling system is in place, but there is still more to come! Here are some planned features:

Oklahoma court says cities may regulate medical marijuana
OKLAHOMA CITY (AP) - The Oklahoma Supreme Court has ruled that cities may approve some regulations of the medical marijuana industry.
The court on Tuesday dismissed an appeal by the city of Broken Arrow in a case filed by marijuana grower Austin Miller. Miller said the city exceeded its authority in 2018 by adopting regulations including a $2,500 annual permit fee on dispensaries and allowing marijuana to only be grown indoors in industrial areas.
The state Supreme Court first overturned a district judge’s injunction blocking the rules. Now, it has ruled that legislative amendments earlier this year to the voter-approved law allowing medical marijuana allows cities to use “standard planning and zoning procedures” but not prevent marijuana businesses from opening.
Miller attorney Ron Durbin called the ruling “a travesty” because he said the amendments apply retroactively. At attorney for the city declined comment.

Pie
Pie is a Go package that provides a toolkit for creating plugins for Go applications.
import "github.com/natefinch/pie"
Why is it called pie?
Because if you pronounce API like “a pie”, then all this consuming and serving of APIs becomes a lot more palatable. Also, pies are the ultimate pluggable interface - depending on what’s inside, you can get dinner, dessert, a snack, or even breakfast. Plus, then I get to say that plugins in Go are as easy as… well, you know.
If you have to explain it to your boss, just say it’s an acronym for Plug In Executables. (but it’s not, really)
About Pie
Plugins using this toolkit and the applications managing those plugins communicate via RPC over the plugin application’s Stdin and Stdout.
Functions in this package with the prefix New
are intended to be used by the
plugin to set up its end of the communication. Functions in this package
with the prefix Start
are intended to be used by the main application to set
up its end of the communication and start a plugin executable.
This package provides two conceptually different types of plugins, based on which side of the communication is the server and which is the client. Plugins which provide an API server for the main application to call are called Providers. Plugins which consume an API provided by the main application are called Consumers.
The default codec for RPC for this package is Go’s gob encoding, however you may provide your own codec, such as JSON-RPC provided by net/rpc/jsonrpc.
There is no requirement that plugins for applications using this toolkit be written in Go. As long as the plugin application can consume or provide an RPC API of the correct codec, it can interoperate with main applications using this process. For example, if your main application uses JSON-RPC, many languages are capable of producing an executable that can provide a JSON-RPC API for your application to use.
Included in this repo are some simple examples of a master process and a plugin process, to see how the library can be used. An example of the standard plugin that provides an API the master process consumes is in the exmaples/provider directory. master_provider expects plugin_provider to be in the same directory or in your $PATH. You can just go install both of them, and it’ll work correctly.
In addition to a regular plugin that provides an API, this package can be used for plugins that consume an API provided by the main process. To see an example of this, look in the examples/consumer folder.
func NewConsumer
func NewConsumer() *rpc.Client
NewConsumer returns an rpc.Client that will consume an API from the host process over this application’s Stdin and Stdout using gob encoding.
func NewConsumerCodec
func NewConsumerCodec(f func(io.ReadWriteCloser) rpc.ClientCodec) *rpc.Client
NewConsumerCodec returns an rpc.Client that will consume an API from the host process over this application’s Stdin and Stdout using the ClientCodec returned by f.
func StartProvider
func StartProvider(output io.Writer, path string, args ...string) (*rpc.Client, error)
StartProvider start a provider-style plugin application at the given path and args, and returns an RPC client that communicates with the plugin using gob encoding over the plugin’s Stdin and Stdout. The writer passed to output will receive output from the plugin’s stderr. Closing the RPC client returned from this function will shut down the plugin application.
func StartProviderCodec
func StartProviderCodec(
f func(io.ReadWriteCloser) rpc.ClientCodec,
output io.Writer,
path string,
args ...string,
) (*rpc.Client, error)
StartProviderCodec starts a provider-style plugin application at the given path and args, and returns an RPC client that communicates with the plugin using the ClientCodec returned by f over the plugin’s Stdin and Stdout. The writer passed to output will receive output from the plugin’s stderr. Closing the RPC client returned from this function will shut down the plugin application.
type Server
type Server struct {
// contains filtered or unexported fields
}
Server is a type that represents an RPC server that serves an API over stdin/stdout.
func NewProvider
func NewProvider() Server
NewProvider returns a Server that will serve RPC over this application’s Stdin and Stdout. This method is intended to be run by the plugin application.
func StartConsumer
func StartConsumer(output io.Writer, path string, args ...string) (Server, error)
StartConsumer starts a consumer-style plugin application with the given path and args, writing its stderr to output. The plugin consumes an API this application provides. The function returns the Server for this host application, which should be used to register APIs for the plugin to consume.
func (Server) Register
func (s Server) Register(rcvr interface{}) error
Register publishes in the provider the set of methods of the receiver value that satisfy the following conditions:
- exported method
- two arguments, both of exported type
- the second argument is a pointer
- one return value, of type error
It returns an error if the receiver is not an exported type or has no suitable methods. It also logs the error using package log. The client accesses each method using a string of the form “Type.Method”, where Type is the receiver’s concrete type.
func (Server) RegisterName
func (s Server) RegisterName(name string, rcvr interface{}) error
RegisterName is like Register but uses the provided name for the type instead of the receiver’s concrete type.
func (Server) Serve
func (s Server) Serve()
Serve starts the Server’s RPC server, serving via gob encoding. This call will block until the client hangs up.
func (Server) ServeCodec
func (s Server) ServeCodec(f func(io.ReadWriteCloser) rpc.ServerCodec)
ServeCodec starts the Server’s RPC server, serving via the encoding returned by f. This call will block until the client hangs up.

Salt beef has a wonderfully unique flavour and is perfect paired with horseradish mash.
For the brine, place all of the brine ingredients into a large saucepan and cover with 5 litres/8¾ pints of water. Bring the mixture to the boil and cook for 2-3 minutes. Remove the pan from the heat and set aside to cool completely.
Place the beef into a large non-metallic container and pour over the cooled brine, (ensure the beef is submerged in the brine). Set aside somewhere cool, preferably the fridge, for 3-5 days. After the soaking time in the brine, rinse the beef brisket and soak in cold water for 24 hours.
Rinse the beef brisket and place into a large saucepan with the vegetables. Cover the brisket completely with cold water and bring the mixture to the boil. Reduce the heat and simmer for 2-2½ hours, or until the beef is very tender. Drain well.
Meanwhile for the horseradish mash, boil the potatoes in a large pan of salted water, for 10-15 minutes, or until tender. Drain well. Return the potatoes to the pan and heat over a low heat for 10-15 seconds to drive off any excess moisture.
Mash the potatoes until smooth using a potato masher or ricer, then beat in the butter. Stir in the horseradish and chives and season, to taste, with salt and freshly ground black pepper.
To serve, carve the beef into thick slices and serve with the horseradish mash, vegetables and gherkins.

Vandy Oil Co (VOC) is an oil and natural gas company with activities in exploration, production, refining and exporting oil as well as exploration and production of natural gas. Its headquarters is located in Nashville, TN.
Reservoir: Porous and permeable rock unit with well-defined boundaries containing commercial amounts of hydrocarbons.
Well: A drilled cased borehole communicating the reservoir with surface installations. It’s a conduit. Serves the purpose of bringing oil or other hydrocarbons - such as natural gas - to the surface.
Rate: Change of a variable with respect to time. Some examples seen here are:
Oil rate: barrels of oil per day (BOPD)
Gas rate: thousands of standard cubic feet per day (MSCF/D)
Water rate: barrels of water per day (BWPD)
Water cut: The ratio or percentage of water in total liquids.
Gas-Oil ratio (GOR): The fraction of gas volume over oil.
Cumulative production: Defined as the gross amount of oil and gas production from an oil reservoir over a particular period of time of the life of a well or reservoir.
The BCS oil field was discovered in November 1953 with the drilling of wells BCS0006 and BCS0007. At that time the VOC decided to test those wells for an extended period of time in order to capture the most of relevant reservoir data.
Commercial production began in 1971 when well BCS0018 was drilled. This proved the real potential of the reservoirs. A total of 44 producing wells were drilled in the field.
The water production in the Eastern part of the field began in September 1987, specifically in well BCS0031. Today’s water cut (the ratio of water in total fluids) is about 75%. In 2007 a water injection pilot project was conducted in a neighbor well to BCS0031, causing a production of injection water in BCS0031. This was the first time that VOC thought that BCS could be a naturally fractured field.
The geological productive formation is a sequence of sandstone–shale rocks from the Eocene age. At BCS Oil Field, we have identified 6 different reservoirs separated by geological faults, impermeable rocks(seals) and fluid contacts. The main characteristics of this oil field are a)the presence of an active aquifer and b)some reservoirs are partially naturally fractured.
The main average properties of the oil fields are:
Depth: 9500 feet
API gravity: 21°
Porosity: 7%
Permeability: 4 md Driven mechanism: Hydraulic, Solution gas
Lifting methods: Gas-lift, sucker rod beam pumping, electro-submersible pumping, progressive cavity pumping

Attributes can be used to control how Json.NET serializes and deserializes .NET objects.
- JsonObjectAttribute - Placed on classes to control how it should be serialized as a JSON object.
- JsonArrayAttribute - Placed on collections to control how it should be serialized as a JSON array.
- JsonPropertyAttribute - Placed on fields and properties to control how it should be serialized as a property in a JSON object.
- JsonConverterAttribute - Placed on either classes or fields and properties to specify which JsonConverter should be used during serialization.
As well as using the built-in Json.NET attributes, Json.NET also looks for the DataContract and DataMember attributes when determining how JSON is to be serialized and deserialized. If both are present the Json.NET serialization attributes take precedence.
[JsonObject(MemberSerialization.OptIn)]
public class Person
{
// "John Smith"
[JsonProperty]
public string Name { get; set; }
// "2000-12-15T22:11:03"
[JsonProperty]
[JsonConverter(typeof(IsoDateTimeConverter))]
public DateTime BirthDate { get; set; }
// new Date(976918263055)
[JsonProperty]
[JsonConverter(typeof(JavaScriptDateTimeConverter))]
public DateTime LastModified { get; set; }
// not serialized
public string Department { get; set; }
}
JsonObjectAttribute
The MemberSerialization flag on this attribute specifies whether member serialization is opt-in (a member must have the JsonProperty or DataMember attribute to be serialized) or opt-out (everything is serialized by default but can be ignored with the JsonIgnoreAttribute, Json.NET's default behavor).
Json.NET serializes .NET classes that implement IEnumerable as an JSON array populated with the IEnumerable values. Placing the JsonPropertyAttribute overrides this behavor and forces the serializer to serialize the class's fields and properties.
JsonPropertyAttribute
JsonPropertyAttribute has a number of uses:
- By default the JSON property will have the same name as the .NET property. This attribute allows the name to be customized.
- Indicates that a property should be serialized when member serialization is set to opt-in.
- Includes non-public properties in serialization and deserialization.
JsonIgnoreAttribute
Excludes a field or property from serialization.
JsonConverterAttribute
The JsonConverterAttribute specifies which JsonSerializer is used to convert an object.
The attribute can be placed on a class or a member. When placed on a class the JsonConverter specified by the attribute will be the default way of serializing that class. When the attribute is on a field or property then the specified JsonConverter will always be used to serialize that value.
The priority of which JsonConverter is used is member attribute then class attribute and finally any converters passed to the JsonSerializer.
public class MemberConverterClass
{
public DateTime DefaultConverter { get; set; }
[JsonConverter(typeof(IsoDateTimeConverter))]
public DateTime MemberConverter { get; set; }
}
This example shows the JsonConverterAttribute being applied to a property.
DateTime date = Convert.ToDateTime("1970-01-01T00:00:00Z").ToUniversalTime();
MemberConverterClass c = new MemberConverterClass
{
DefaultConverter = date,
MemberConverter = date
};
string json = JsonConvert.SerializeObject(c, Formatting.Indented);
Console.WriteLine(json);
//{
// "DefaultConverter": "\/Date(0)\/",
// "MemberConverter": "1970-01-01T00:00:00Z"
//}

Background
- Experts and Expert Performance (Ericsson et al. 2006)
- Experts have accumulated knowledge
- Experts have specialized mental skills
- Experts have applicable experience through targeted practice
- Usually some form of restriction becoming a member of a profession, occupation, guild,
or obtaining a credential from a respected institution
- Expert performance do not transfer to other areas
Background
- Lay Expertise (Prior 2003)
- No consensus on what defines a Lay expert
- Most research in lay expertise comes from medical sociology and epidemiology
- Lay expertise gained through personal experience
- Learning the language is typical of lay experts
- Engaged in advocacy AIDS, breast cancer (Barker 2011, Epstein 1995)
Background
- The Dunning-Kruger Effect (Dunning 2011)
- The less one knows about something the more errors they will make
- Lack of knowledge prevents seeing their errors made
- The faster someone obtains an answer the more confident they are about those answers
Background
- Self-Efficacy (Ross and Mirowsky 2013)
- Self-efficacy is a belief of the amount of control you have over your life
- Education is the best way to increase self-efficacy
Putting it together
- There are more lay experts then the literature has indicated
- Lay expertise gained through personal experience
- The only person who truly knows what the illness is like is the patient, only
they know how it feels, affects their daily routines, relationships, etc. (Zola
1973)
- Engaged in advocacy
- People share their own health recommendations based on their own health
experiences within their social networks (Liu, King and Bearman 2010)
Putting it together (cont.)
- The Internet (through easily digestible information) is making more lay experts who
experience Dunning-Kruger
- Learning the language is typical of lay experts
- Sites like WebMD, Wikipedia, Mayo Clinic, etc. provide an easy way to learn the
language
- The faster someone obtains an answer the more confident they are about those answers
- It is very fast and seems uncomplicated to look up something on Google/Bing then
to do the research necessary to understand a medical condition
- The move toward consumerism (ranking, ratings, etc.) in the medical field is leading
to an attitude of ‘customer knows best’ when interacting with medical professionals
(Hardey 1999)
Conceptual Definitions
- Experts and Expert Performance
- Lay Expertise
- The Dunning-Kruger Effect
Research Question
- Is confidence in the understanding of information obtained affected by the source of the
information?
- Is confidence in the understanding of information obtained affected by the simplicity of the
information?
Hypotheses
- There will be an increase in confidence in understanding of information the simpler the
information presented
- There will be an increase in confidence in understanding of information when that information is
on the Internet
Experimental Setup
- IV - Source of information, Format of information
- DV - Confidence in their understanding of the information, Retention of the information
- Deception - The duration of time it takes to forget recently learned information (will learn
for 10 min then wait 10 min before tested)
- Manipulation - Three groups all given 10 minutes to learn as much as they can about
hypohidrotic ectodermal dysplasia from the source given to them
- Source will be a textbook entry about hypohidrotic ectodermal dysplasia
- Source will be the textbook entry made to look like Wikipedia
- Source will be the Wikipedia entry on hypohidrotic ectodermal dysplasia
Experimental Procedure
- Participants will take a pretest asking about their experience with medical/genetic
information (classes, work experience, etc.) and their confidence in understanding difficult
material quickly
- Participants will be randomly assigned to one of three groups with different sources of
information
- After 10 minutes of trying to learn as much information as possible they will wait 10
minutes during which they will take a test asking them how well they think they retained the
information
- 10 minutes after the material has been taken they will take a information retention test
- A debriefing will then occur

Explaining webSPAD¶
The Lisp file webspad.lisp
comprises the interface between FriCAS
(essentially package BOOT
) and the the webserver (package
HUNCHENTOOT
).
Package WEBSPAD
¶
First, there is a package WEBSPAD
:
(defpackage webspad
(:use common-lisp)
(:documentation "see docs"))
In package WEBSPAD
((in-package :webspad)
), we define the data
structures that will be interchanged by a HTML client and server. Instead
of defclass
we only use defstruct, which is sufficient for our
purposes.
(defstruct ws-format
(algebra boot::|$algebraFormat|)
(tex boot::|$texFormat|)
(html boot::|$htmlFormat|)
(mathml boot::|$mathmlFormat|)
(formula boot::|$formulaFormat|)
(fortran boot::|$fortranFormat|)
(texmacs boot::|$texmacsFormat|)
(openmath boot::|$openMathFormat|))
Each of the entries indicates whether the correspondig format is active or
not, i.e. the types of the slots are booleans (T
or NIL
). The
slots are controlled by the FriCAS commands set output x on/off
.
There are two similar structures, ws-out-stream
and webspad-data
,
where the latter is the one which will be sent to the client (json encoded).

functions
Minimal embedding of Hunchentoot¶
The following code provides a concise example how to embed Hunchentoot
into a running FriCAS instance. The GET
and POST
method will be
demonstrated by using urls in a web-browser and a short Python code
respectively.
The code¶
Paste the following code into a file minserver.lisp
(load "~/quicklisp/setup")
(ql:quickload :hunchentoot)
(in-package :boot)
;;; Config
(defparameter +port+ 4242)
;;; SPAD eval
(defun spad_eval (code)
(let ((*package* (find-package :boot))
(alg (boot::|parseAndEvalToString| code)))
(format nil "~{~A~%~}" alg)))
;;; WEB server
(hunchentoot:define-easy-handler (fricas-eval :uri "/eval") (code)
(setf (hunchentoot:content-type*) "text/plain")
(format nil "~A~%" (spad_eval code)))
(hunchentoot:start (make-instance 'hunchentoot:easy-acceptor :port +port+))
;;; add :address "localhost" if you wish local access only!
;;; test example: http://localhost:4242/eval?code=D(x^n,x,6)
Load server¶
We will do all steps manually for the sake of clarity. Start FriCAS and
load the file minserver.lisp
:

Open a web browser¶
Now open a web browser (some terminal based browsers like w3m, lynx or links, do not accept all urls as e.g. Firefox does, however, when using quotes most urls will work). Enter the following url:
http://localhost:4242/eval?code=D(x^n,x,6)
The result in the browser window should exactly look like as below:
6 5 4 3 2 n - 6
(n - 15n + 85n - 225n + 274n - 120n)x
Type: Expression(Integer)
Explanation¶
The connection of the url example above with the lisp code is almost obvious:
(fricas-eval :uri "/eval") (code)
The easy handler expects a query ?
and one variable code
. Then this
query will be evaluated and the result formatted and written to the client.
GET and POST¶
Two commonly used methods for a request-response between a client and server are:
GET and POST.
GET - Requests data from a specified resource
POST - Submits data to be processed to a specified resource
The GET Method¶
Note that the query string (name/value pairs) is sent in the URL of a GET request:
/test/demo_form.asp?name1=value1&name2=value2
Restrictions: The GET method adds the data to the URL; and the length of a
URL is limited (maximum URL length is 2048 characters and ASCII
characters only are allowed.
Certain characters have a special meaning in an URL, so url encoding must follow some rules (HTML URL Encoding Reference).
There are some online URL en/decoders which will encode more complex input, for instance:
integrate(1/(1+x^2),x)
reads in encoded form as:
integrate(1%2F(1%2Bx%5E2)%2Cx)
The latter string can be used in a url, whereas the former will not be
accepted (e.g. due to the plus character +
).
The POST Method¶
Note that the query string (name/value pairs) is sent in the HTTP message body of a POST request:
POST /test/demo_form.asp HTTP/1.1
Host: w3schools.com
name1=value1&name2=value2
The restrictions of the GET method do not apply here, however, to get a full overview consult the link above. There also are other HTTP request possibilities.
Python example for POST¶
import requests
url = 'http://localhost:4242/eval'
payload = {'code': 'D(x^n,x,8)'}
r = requests.post(url, data=payload)
print(r.text)
Live action:
C:\Users\nilqed>python
Python 2.7.10 (default, May 23 2015, 09:40:32) [MSC v.1500 32 bit (Intel)]
Type "help", "copyright", "credits" or "license" for more information.
>>> import requests
>>> url = 'http://localhost:4242/eval'
>>> payload = {'code': 'D(x^n,x,8)'}
>>> r = requests.post(url, data=payload)
>>> r
<Response [200]>
>>> print(r.text)
8 7 6 5 4 3 2 n - 8
(n - 28n + 322n - 1960n + 6769n - 13132n + 13068n - 5040n)x
Type: Expression(Integer)
>>>
With the POST method we can use high payloads and there are many languages with HTTP support libraries.
