status (blue|cyan|green|magenta|orange|red|white|yellow|available|busy|dnd|away|incoming)
status (off|on)
toggle-status
Both commands either set the presence light device to the specified color or to the color associated with the specified status.

The command status on
returns the presence light to the last status set through toggle-status
.
The commands support the following presence light devices:
toggle-status
uses a semaphore file in %TEMP%\presence-light-busy.txt
to keep track of the current status. If the light is updated by other applications the state of the file might not match the actual state of the light. Using toggle-status
multiple times (at most 2 times) will bring the light back into the desired state.
In addition to the the command line tool, a shortcut named "Update Status" has been added to the desktop, which will call toggle-status
to update the status of the light.

Welcome to Tie & Dye CSS, the first mega and very artistic fancy CSS library that brings all the legendary CSS tricks into your designs. Free and open source, learn more about it below or feel free to contribute!
The library can be easily setup for projects as a CDN, Npm or Downloaded as a zip file, use the options below and choose the most convenient way to you.
Click on the icons on the left of the links above to copy or download the lib CSS file and then paste the link inside the head tag in your html or if you downloaded the file you can pull it in as you can link to a normal style sheet and below are tips to get you started!
Hope you're using sass cause it's the only work around supported per the current version, and Vscode preferably so that you can get the live sass compiler extension to smooothen things up and then if you used NPM scripts, just import the file into your code or use the CDN link to do the same. But if you downloaded the library files and you just wanna use as is, just pull in the file into your code. For some customization and advanced usage, read on below.
For using the partials, import the partial files below in thier order.
- tie-and-dye.base
- tie-and-dye.config
- tie-and-dye.colors
- tie-and-dye.tricks
Where the base partial holds the basic styles or defalut resets, the config with the variables and user customizable styles, then the colors with all the color schemes and paletes and tricks which holds all the magic mixins. And we will break down each file below!
The library comes with it's own CSS reset to get you started, it's preset is inspired by various popular resets like modern reset, normalize and others with just our flavor blended in. However never the less you should not mistake Tie & Dye CSS Library and CSS frameworks, this is just a CSS library comprising of various CSS libraries to bring cool CSS tricks into your designs from icon animations without Javascript to text gradient and much more but it can surely be used along popular CSS frameworks like Tailwind and Bootstrap.
Tie & Dye CSS is built using Sass, just to be sassy about this we wanted it to have all the super powers of enhanced CSS. But worry not if you don't use sass cause the library will soon also be available in plain CSS as a compilation of the sass version but for the time being we're just sassy!
This library is built by devs for devs, by community for the community and all it's tricks belong to thier respective artists but we still take pride that someone someday somewhere sometime will not have to rewrite already existing CSS just to add a simple twist into his/her design.
So to break it down, the library has 5 .scss partials and one full file which encompasses all the the 5 partials, and it's important to import these in order as we specify.


Dedicated to curating and developing innovative methods of computational text analysis for the research community at UC Berkeley.
Find Out MoreDuring the Spring of 2015 a group of UC Berkeley researchers including faculty, graduate students, and other affiliated researchers realized that there was no centralized community to support the innovative methodological experimentation with rapidly evolving field of computational text analysis. To support these efforts, and to develop a broad community capable of leveraging these new tools to contribute to research in a wide range of fields, we launched the CTAWG. We meet twice a month to share research, provide technical workshops, and to offer space to support ongoing analysis. We welcome new members and we have lots of ways for you to get involved so please be in touch if you'd like more information.
Get Involved!We meet every other week on Fridays from 1:00-2:00 PM PST over Zoom. Meetings are open to the Berkeley and UCSF communities - please make sure to register. We're planning to have nine meetings for Spring 2021: 1/29, 2/5, 2/19, 3/5, 3/19, 4/2, 4/16, 4/30, 5/7.
We host a lively ongoing discussion on our listserve featuring event listings, workshops, and news for the computational text analysis community at UC Berkeley. To join our listserv fill out a registration form at D-Lab.
We’re compiling a list of critical citations, both technical and applied, that can guide future computational text analysis. To see what we have, or to add your own resources, visit the CTAWG at Zotero, log in, and request an inviation to join.
We do our best to keep records of our meetings, plans, and accomplishmnets. If you missed something and you'd like to get caught up, or if you'd like to contribute notes or suggestions, check out or documentation page.
Computational text analysis methods are flexible enough to provide valuable tools for researchers with a clear question who are interested in testing a hypothesis, or to provide fruitful preliminary insight into a broader research topic.
The internet has created unparalleled access to huge volumes of digital text (e.g. Project Gutenberg, Wikipedia, LexisNexis, Twitter, the web itself). While designing an analysis around such data can save time, these methods can be used on virtually anything in the form of text.
The plethora of digital text that now exists is rarely available in interoperable or standardized formats. Analyzing this data often calls for what can be tedious and time consuming efforts to ensure that your analysis captures only the data of interest.
A wide array of methods exist which leverage modern computing power to analyze text. Among the many methods available are those which can be used to count words, discover latent topics in text, or to classify new documents bases on rules.
Due to the novelty, sophistication, and complexity of many text analysis methods, interpretation of output and reporting of results require extra care. Documenting and justifying choices at this stage is critical.
Presenting or publishing results of computational text analysis often benefit from visual summaries. In addition to traditional quantitative statistical software (e.g. R, Stata, Excel, Python) a few specific options are available for text analysis (e.g. Mallet).
If you have additional questions, or if you'd like to speak with a group organizer, don't hesitate to contact us via our email. You can also use the D-Lab's contact form for help with individual research projects or you can choose the CTAWG organizers from the D-Lab CTAWG page for their contact information.

delete-file
filespec ⇒ t
filespec—a pathname designator.
Deletes the file specified by filespec.
If the filespec designator is an open stream, then filespec and the file associated with it are affected (if the file system permits), in which case filespec might be closed immediately, and the deletion might be immediate or delayed until filespec is explicitly closed, depending on the requirements of the file system.
It is implementation-dependent whether an attempt to delete a nonexistent file is considered to be successful.
delete-file returns true if it succeeds, or signals an error of type file-error if it does not.
The consequences are undefined if filespec has a wild component, or if filespec has a nil component and the file system does not permit a nil component.

If the deletion operation is not successful, an error of type file-error is signaled.
An error of type file-error might be signaled if filespec is wild.


The odsFacets widget displays filters based on a dataset or a domain's catalog of datasets. This widget allows to dynamically refine on one or more categories for the defined context (i.e., each filter being composed of several categories, which are values of the field the filter is based on).
For example, odsFacet can be used to refine the data displayed in a table (odsTable) to see only the desired data.
Suppose the widget is used without any configuration. In that case, it will display by default filters from all the "facet" fields of a dataset when used with a Dataset Context. It will display by default filters from typical metadata from a dataset catalog when used with a Catalog Context.
<ods-facets context="mycontext"></ods-facets>
odsFacet
The odsFacet widget is a widget that can only be used based on odsFacets. It is used to configure which facets should be displayed by odsFacets, since odsFacets used alone does not allow to display only specific facets among all the default ones of the dataset. odsFacet supports the following parameters:
- name
- sort
- visibleItems
- hideIfSingleCategory
- hideCategoryIf
Note: these parameters are the same as some used for odsFacets. For more information about configuration, see the odsFacets parameters table.
odsFacet allows to configure which facets are displayed using the name parameter.
<ods-facets context="mycontext">

First field

<ods-facet name="myfield"></ods-facet>

Second field

<ods-facet name="mysecondfield"></ods-facet>
</ods-facets>
Regular HTML is supported within the odsFacet tag to change the display template of each category. The available variables within the template are:
facetName
: name of the field that the filter is based on
category.name
: value of the category
category.path
: complete path to the category, including hierarchical levels
category.state
: refined, excluded, or displayed
An ng-non-bindable
wrapper element must be used around the display template for it to work properly.
Note: There must not be any space character between the odsFacet tag and the span element, as it may prevent the widget from working properly.
<ods-facets context="mycontext">
<ods-facet name="myfield">
{{category.name}} @ {{category.state}}
</ods-facet>
</ods-facets>


Charles Schwab eyes purchase of TD Ameritrade: reports
by Noah ManskarCharles Schwab is in talks to buy TD Ameritrade — a blockbuster brokerage deal that could be announced as early as Thursday, reports said.
Schwab, headquartered in San Francisco, will shell out a staggering $26 billion for Nebraska-based Ameritrade, according to Fox Business News.
Shares of TD Ameritrade shares soared 17.21 percent in premarket trading, while Schwab’s slid 2.26 percent as of 6 a.m.
Neither Charles Schwab nor TD Ameritrade immediately responded to requests for comment.


Build my house according to my need
Who ever plans to build a new house, you will think about the cost and the quality. If you are going to do with very low cost,some times the quality of the house may be not in the expected level. Lot of people while building their house, they got to know that cost is getting increase due to misunderstanding, some cost for other needs and lack of knowledge. Best thing is before you start your dream, ask some help with the consultations. Before you start
- The size of the house
- The fundamental design of the house
- The type of materials used
- construction cost.
Contact Ehand
After you contact with us, we will give contact various feild specific consultations to you to plan your construction

This SRFI descibes a new syntax for Scheme, called I-expressions, whith equal descriptive power as S-expressions. The syntax uses indentation to group expressions, and has no special cases for semantic constructs of the language. It can be used both for program and data input.
It also allows mixing S-expressions and I-expressions freely, giving the programmer the ability to layout the code as to maximize readability.

Normally INSTALLATION/bin/hg
but you could specify another name
such as INSTALLATION/my-mercurial.py
or even look for Mercurial
in the default path (leaving installation directory blank) using just hg
.
If you are configuring per-node tool home locations,
you may leave the installation directory undefined on some nodes,
in which case just hg
(i.e., from $PATH
) is used.

var breakTag = (is_xhtml || typeof is_xhtml === 'undefined') ? '' : '

Why not use first regex instead the second one? (without [^>\r\n]?)
return (str + '').replace(/(\r\n|\n\r|\r|\n)/g, breakTag + '$1');
return (str + '').replace(/([^>\r\n]?)(\r\n|\n\r|\r|\n)/g, '$1' + breakTag + '$2');

Taking into account different newline combinations (\r\n, \r, \n), function should return

@ John Peterson: Of course: that's not at all like PHP. And that's what we're trying to recreate here: So the main version should be as is it right now.
However. Just like there's a namespaced version of PHP.JS, I think it should be possible for us to generate prototype versions with the compiler.
Currently this is a low priority for me and I would first like to create a public interface to the compiler on the phpjs.org site.
But I will keep this in mind as a future feature!
Brett Zamir
on 2009-01-14 10:00:20
I should add the extra qualification that overloading the Object or Array prototype would probably be quite objectionable to many and need some serious revising of the PHP-JS functions (which I'm thinking should probably be revised regardless) to check for hasOwnProperty in each iterating for loop.
Brett Zamir
on 2009-01-14 09:53:21
HI John,
I think concerns on this range from "What happens if a standard version gets implemented later?" to "Will this interfere with other implementations added to the prototype (as a kind of "global" problem?"), etc.. However, I personally think this could be very convenient for those willing to take the risk (or who reset the prototype after their code is done with it).
Maybe when we get the string functions done ( ;) ), we can make one version of the PHP-JS package which adds to the prototype (also for Array, Object, Number, or maybe Function or Boolean if you can think of a reason!), as I'm hoping we can see a configurable version made at some point (as an independent project, if not through Kevin's official version).

Why not just do this so much simplier...
String.prototype.nl2br = function() {
var breakTag = '

return (this + '').replace(/([^>]?)\n/g, '$1'+ breakTag +'\n');
}
then you can just do:
mystring.nl2br()

Hi.
There seems to be a minor flaw in the function for strings that start with a line-breaks, or have multiple consecutive line-breaks.
Using this:
nl2br("\nOne\nTwo\n\nThree\n")
it leaves out the first new-line and replaces the two new-lines between "Two" and "Three" with a single break.
Making the regex non-greedy seems to fix this tho:
return (str + '').replace(/([^>]?)\n/g, '$1
\n');
Additionally, PHP 5.3 will accept a second parameter, indicating whether the break should be XHTML compliant or not.
This would allow for that as well:
function nl2br( str, is_xhtml ) {
breakTag = "
";
if(typeof is_xhtml == "boolean" || is_xhtml == false) {
breakTag = "
";
}
return (str + '').replace(/([^>]?)\n/g, '$1'+ breakTag +'\n');
}

Here's the part of my code and it 100% works now:
var nfull = document.getElementById('full').value;
nfull = nfull.replace(/([^>])\\n/g, '$1

document.getElementById('txtpr').innerHTML = nfull;

There are a few inconsistencies here:
first off, the replacement text should be "
\n" (with the space before the backslash in
 and including the newline). Also, I don't have time to do this, but you may want to check out how PHP handles \r\n and \r in this function, as it may be useful to implement support for if the PHP function does it.

Parallelising Python with Threading and Multiprocessing
One aspect of coding in Python that we have yet to discuss in any great detail is how to optimise the execution performance of our simulations. While NumPy, SciPy and pandas are extremely useful in this regard when considering vectorised code, we aren't able to use these tools effectively when building event-driven systems. Are there any other means available to us to speed up our code? The answer is yes - but with caveats!
In this article we are going to look at the different models of parallelism that can be introduced into our Python programs. These models work particularly well for simulations that do not need to share state. Monte Carlo simulations used for options pricing and backtesting simulations of various parameters for algorithmic trading fall into this category.
In particular we are going to consider the Threading library and the Multiprocessing library.
Concurrency in Python
One of the most frequently asked questions from beginning Python programmers when they explore multithreaded code for optimisation of CPU-bound code is "Why does my program run slower when I use multiple threads?".
The expectation is that on a multi-core machine a multithreaded code should make use of these extra cores and thus increase overall performance. Unfortunately the internals of the main Python interpreter, CPython, negate the possibility of true multi-threading due to a process known as the Global Interpreter Lock (GIL).
The GIL is necessary because the Python interpreter is not thread safe. This means that there is a globally enforced lock when trying to safely access Python objects from within threads. At any one time only a single thread can acquire a lock for a Python object or C API. The interpreter will reacquire this lock for every 100 bytecodes of Python instructions and around (potentially) blocking I/O operations. Because of this lock CPU-bound code will see no gain in performance when using the Threading library, but it will likely gain performance increases if the Multiprocessing library is used.
Parallelisation Libraries Implementation
We are now going to utilise the above two separate libraries to attempt a parallel optimisation of a "toy" problem.
Threading Library
Above we alluded to the fact that Python on the CPython interpreter does not support true multi-core execution via multithreading. However, Python DOES have a Threading library. So what is the benefit of using the library if we (supposedly) cannot make use of multiple cores?
Many programs, particularly those relating to network programming or data input/output (I/O) are often network-bound or I/O bound. This means that the Python interpreter is awaiting the result of a function call that is manipulating data from a "remote" source such as a network address or hard disk. Such access is far slower than reading from local memory or a CPU-cache.
Hence, one means of speeding up such code if many data sources are being accessed is to generate a thread for each data item needing to be accessed.
For example, consider a Python code that is scraping many web URLs. Given that each URL will have an associated download time well in excess of the CPU processing capability of the computer, a single-threaded implementation will be significantly I/O bound.
By adding a new thread for each download resource, the code can download multiple data sources in parallel and combine the results at the end of every download. This means that each subsequent download is not waiting on the download of earlier web pages. In this case the program is now bound by the bandwidth limitations of the client/server(s) instead.
However, many financial applications ARE CPU-bound since they are highly numerically intensive. They often involve large-scale numerical linear algebra solutions or random statistical draws, such as in Monte Carlo simulations. Thus as far as Python and the GIL are concerned, there is no benefit to using the Python Threading library for such tasks.
Python Implementation
The following code illustrates a multithreaded implementation for a "toy" code that sequentially adds numbers to lists. Each thread creates a new list and adds random numbers to it. This has been chosen as a toy example since it is CPU heavy.
The following code will outline the interface for the Threading library but it will not grant us any additional speedup beyond that obtainable in a single-threaded implementation. When we come to use the Multiprocessing library below, we will see that it will significantly decrease the overall runtime.
Let's examine how the code works. Firstly we import the threading
library. Then we create a function list_append
that takes three parameters. The first, count
, determines the size of the list to create. The second, id
, is the ID of the "job" (which can be useful if we are writing debug info to the console). The third parameter, out_list
, is the list to append the random numbers to.
The __main__
function creates a size
of $10^7$ and uses two threads
to carry out the work. It then creates a jobs
list, which is used to store the separate threads. The threading.Thread
object takes the list_append
function as a parameter and then appends it to the jobs
list.
Finally, the jobs are sequentially started and then sequentially "joined". The join()
method blocks the calling thread (i.e. the main Python interpreter thread) until the thread has terminated. This ensures that all of the threads are complete before printing the completion message to the console:
# thread_test.py import random import threading def list_append(count, id, out_list): """ Creates an empty list and then appends a random number to the list 'count' number of times. A CPU-heavy operation! """ for i in range(count): out_list.append(random.random()) if __name__ == "__main__": size = 10000000 # Number of random numbers to add threads = 2 # Number of threads to create # Create a list of jobs and then iterate through # the number of threads appending each thread to # the job list jobs = [] for i in range(0, threads): out_list = list() thread = threading.Thread(target=list_append(size, i, out_list)) jobs.append(thread) # Start the threads (i.e. calculate the random number lists) for j in jobs: j.start() # Ensure all of the threads have finished for j in jobs: j.join() print "List processing complete."
We can time this code using the following console call:
time python thread_test.py
It produces the following output:
List processing complete. real 0m2.003s user 0m1.838s sys 0m0.161s
Notice that the user
and sys
both approximately sum to the real
time. This is indicative that we gained no benefit from using the Threading library. If we had then we would expect the real
time to be significantly less. These concepts within concurrent programming are usually known as CPU-time and wall-clock time respectively.
Multiprocessing Library
In order to actually make use of the extra cores present in nearly all modern consumer processors we can instead use the Multiprocessing library. This works in a fundamentally different way to the Threading library, even though the syntax of the two is extremely similar.
The Multiprocessing library actually spawns multiple operating system processes for each parallel task. This nicely side-steps the GIL, by giving each process its own Python interpreter and thus own GIL. Hence each process can be fed to a separate processor core and then regrouped at the end once all processes have finished.
There are some drawbacks, however. Spawning extra processes introduces I/O overhead as data is having to be shuffled around between processors. This can add to the overall run-time. However, assuming the data is restricted to each process, it is possible to gain significant speedup. Of course, one must always be aware of Amdahl's Law!
Python Implementation
The only modifications needed for the Multiprocessing implementation include changing the import line and the functional form of the multiprocessing.Process
line. In this case the arguments to the target function are passed separately. Beyond that the code is almost identical to the Threading implementation above:
# multiproc_test.py import random import multiprocessing def list_append(count, id, out_list): """ Creates an empty list and then appends a random number to the list 'count' number of times. A CPU-heavy operation! """ for i in range(count): out_list.append(random.random()) if __name__ == "__main__": size = 10000000 # Number of random numbers to add procs = 2 # Number of processes to create # Create a list of jobs and then iterate through # the number of processes appending each process to # the job list jobs = [] for i in range(0, procs): out_list = list() process = multiprocessing.Process(target=list_append, args=(size, i, out_list)) jobs.append(process) # Start the processes (i.e. calculate the random number lists) for j in jobs: j.start() # Ensure all of the processes have finished for j in jobs: j.join() print "List processing complete."
We can once again time this code using a similar console call:
time python multiproc_test.py
We receive the following output:
List processing complete. real 0m1.045s user 0m1.824s sys 0m0.231s
In this case you can see that while the user
and sys
times have reamined approximately the same, the real
time has dropped by a factor of almost two. This makes sense since we're using two processes. Scaling to four processes while halving the list size for comparison gives the following output (under the assumption that you have at least four cores!):
List processing complete. real 0m0.540s user 0m1.792s sys 0m0.269s
This is an approximate 3.8x speed-up with four processes. However, we must be careful of generalising this to larger, more complex programs. Data transfer, hardware cache-levels and other issues will almost certainly reduce this sort of performance gain in "real" codes.
In later articles we will be modifying the Event-Driven Backtester to use parallel techniques in order to improve the ability to carry out multi-dimensional parameter optimisation studies.

Numerical Continuation Routine¶
To conduct the numerical continuation of the points produced by the mass conservation and semi-diffusive approaches, we use the very well developed software AUTO. In particular, we use the updated version AUTO 2000 made accessible through Libroadrunner and its extension rrplugins [SBG+15]. In the examples we have provided throughout this documentation we choose a set configuration of the parameters to run on all of the points found by the optimization routine. Although this is sufficient for detecting if bistability occurs in a particular network, if one wants to identify possible true physiological values, then it is best to consider each point individually while varying AUTO parameters. This is because if the points exist with varying ranges in the point sets then a set AUTO configuration may miss the detection of bistability for certain parameter settings.
Given most users may be unfamiliar with numerical continuation, in this section we provide some tips to consider when
conducting the numerical continuation routine. To begin, it is first suggested to consider the available parameters in
AUTO parameters
. Note that as said in earlier sections, one should not set ‘SBML’
or ‘ScanDirection’ in these parameters as these are automatically assigned. Further descriptions of these parameters
can be found in the older AUTO documentation. Of the
available parameters, the most important are NMX, RL0, RL1, A1, DSMIN, and DSMAX, although more advanced users may
find other parameters useful. The following is a short description of these parameters:
1. NMX is the maximum number of steps the numerical continuation is able to take. If one is using smaller values for DSMIN and or DSMAX it is suggested that NMX be increased. Note that an increase in NMX may result in longer run times.
2. DSMIN is the minimum continuation step size. A smaller DSMIN value may be beneficial if the values for the species’ concentrations or principal continuation parameter is smaller than the default value provided. Larger values may be helpful in some contexts, but for most examples the parameter should be left at its default value.
3. DSMAX is the maximum continuation step size. A large DSMAX is necessary when considering the physiological values
provided by crnt4sbml.CRNT.get_physiological_range()
as this produces larger values for the species’
concentrations and principal continuation parameters. A smaller DSMAX is also beneficial for both producing smoother
plots and identifying special points. Although a smaller DSMAX will increase the runtime of the continuation.
4. RL0 is the lower bound for the principal continuation parameter (PCP). This value should be set at least a magnitude smaller than the starting value of the PCP, with 0.0 being the absolute minimum value that should be provided.
5. RL1 is the upper bound for the principal continuation parameter (PCP). This value should be set at least a magnitude larger than the starting value of the PCP. An arbitrarily large value should not be used as this range can drastically affect the discovery of limit points and require fine tuning of DSMAX and DSMIN.
6. A1 is the upper bound on the principal solution measure. The principal solution measure used for differential equations is the -norm defined as follows where is the number of species and is the solution to the ODE system for species
.
Although this parameter is somewhat difficult to monitor in the current setup of the continuity analysis, it is usually best to set it as a magnitude or two larger than the largest upper bound established on the species’ concentrations.
To configure these parameters, it may be useful to see what special points are produced by the numerical continuation run. This can be done in both approaches by adding ‘print_lbls_flag=True’ to the run_continuity_analysis functions. For a description of the possible points that may be produced consider the section ‘Special Points’ in the XPP AUTO documentation. For the purposes of detecting bistability, the most important special points are limit points (LP). These points often mark a change in the stability of the ODE system and are more likely to produce overlapping stable and unstable branches that lead to bistability. It is the search for these special points that should guide the configuration of the AUTO parameters.
In addition to limit points, finding a set of two endpoints can be useful in determining if the ranges for the principal continuation parameter are appropriate. If no endpoints are found, then it is likely that the bounds chosen for the principal continuation parameter need to be changed. Note that when ‘print_lbls_flag=True’ is added to the run_continuity_analysis functions, the numerical continuation is first ran in the Positive direction and if no multistability is found, then the routine is ran in the Negative direction. This may result in two printouts per point provided. This switching of directions can often produce better results for numerical continuation runs.

Profides classes (mostly SearchBeans) for making dccd information searchable (indexing and querying)
Searching in DCCD
Search types
DCCD supports three types of searches:
- My Projects search on the "My Projects" page of a logged-in member (refine)
finds Projects of the member (archived and draft) and everything can be found and seen.
- Public search with the input at the top of each page when NOT logged-in
Only archived Objects can be found and the results show only the "open acces" information (with the location exception)
When a result is selected for getting more detailed information, the user is redirected to the login page.
- Member search with the input at the top of each page when logged-in (also advanced search)
Only archived objects, with respect to the permissions described by the next section.
When a result is selected for getting more detailed information,
the complete project is made available showing the project structure (entity tree),
but the entities content only when there is permissions
Permission
Only when logged-in you can have permission to see more than the socalled "open acces" information (with the location exception).
For each (archived) project the manager can specify by the defaultlevel, what other members can see.
What makes the permissions complex is that for each member an exception can be made and
more permission then the default can be granted for a specific project.
Although the display of information is respecting these complex permission rules, the search add another challenge:
It should not be possible to find Objects by a match with a piece of information that the user is also not permitted to see!
The searching is facilitated by Solr,
and for changes in the SearchBeans we need to edit the Solr configuration files solrconfig.xml and schema.xml.
The search results are displayed by the classes in the following package:
@see nl.knaw.dans.dccd.web.search
The ProjectEntity and ObjecctEntity classes implement a fillSearchBean method.
@see nl.knaw.dans.dccd.model.enties
Project and object information is displayd by the datapanels
@see nl.knaw.dans.dccd.web.datapanels


Yesterday we had a distinguished guest at the South Pole. The Prince of Monaco came to visit the station and gave a short speech. He is on a tour of 26 Antarctic stations promoting environmentalism and Monaco recent signing of the Antarctic Treaty. In honor of the Prince’s visit I thought I would talk a little about people who visit the pole.
Every year there are some private flights that are chartered to the South Pole and the always fill up. You can sign up through a company known as ALE, but it is quite expensive. Roughly $38,000 to visit the pole.
Last week we had an ALE fight come in with some interesting people. One was a rich guy from Alabama that bought half of of the station’s store out. Another was a very old lady, probably over 80. Apparently she had to be on oxygen the entire time and almost collapsed walking back to the plane.
There are also guests hosted by the NSF. The Prince of Monaco was one of them. On my flight to the pole was the former president of Slovakia. I really don’t know why he was here, or what interest he had in Antarctica.
Next week there is a group from the House Committee on Commerce, Justice, and Science. I don’t know if any congressmen are in the group, but I will definitely keep you all updated.

Leslie created CollegeMatters because she is passionate about helping students reach their personal potential through thoughtful college choices.
A consulting practice is created assisting high school students and their parents navigate the college selection, application and admissions process.
She has helped students apply to, and be accepted at, a wide range of colleges from the Ivy Leagues to state schools (inside and outside of California) to small private schools throughout the country and abroad.
With over 14 years of practice, Leslie has helped over 100 students get into college, including: University of California, Stanford, Pomona, Oberlin, University of San Diego, University of Southern California, Vassar College, Babson College, Yale, and more.
"Leslie designed a personalized strategy that helped me stay organized, facilitated my decision-making, and kept my parents informed."
“Leslie gave me the tools I needed to make it through this process and come out of it fulfilled and successful. I am now going to the college that I not only love, but is also right for me.”
"Leslie helped my with my college essay and showed me the path to get into a great college."
Applying to college requires a great deal of time, effort and organization. It often becomes a source of stress and friction between students and their parents. Leslie is able to lessen any sources of tension by being an objective consultant who supports both the students and their parents.

mdpress is a tool for making HTML presentations for Markdown. Here’s how it works:
# Chicken Chicken Chicken
## By Chicken
---
# Chicken
- Chicken
- Chicken Chicken
Save that as test.md
and then use mdpress test.md
to convert it to a presentation.
mdpress
uses Redcarpet, so it can parse whatever markdown you throw at it.
We use the horizonal rule, ---
, to indicate the start of a new slide.
So far the slide transitions haven’t been that exciting. Let’s spice them up.
Below the ---
, type:
= data-x="1000"
And re-compile with mdpress test.md
(you might have to delete your old presentation directory first).
Aha! Not bad! We specify transformations with = [list of transformations]
as the first line of whatever slide we want to apply the transformation to.
We could have written
= data-x="1000" data-scale="2"
To make it scale as well as swipe.
data-x
, data-y
, data-z
: positioningdata-rotate-x
, data-rotate-y
, data-rotate-z
, data-rotate
: rotation (data-rotate
and data-rotate-z
are exactly the same)data-scale
: scaleid
: used as the slide link. For example, if you use id=intro
, you can link to that slide using index.html#/intro
.See impress.js for a broader description of these.
Adding this syntax to Markdown feels like kind of a hack, but it’s concise. I’m open to suggestions for something better.
Earlier, our workflow involved having to delete the old presentation and recompile every time we made an edit. The better choice is to use the automatic mode:
mdpress -a [filename.md]
Now, mdpress
will keep running and check for updates to your markdown file. It will automatically recompile the presentation for you, so you can seamlessly edit your markdown and view your changes instantly.
mdpress
comes with a default stylesheet, plus a few more. See the full list of available stylesheets with
mdpress -l
Or specify a stylesheet to use with
mdpress -s [stylesheet]
If you make your own stylesheets, send me a pull request and I’ll add them to the list! See below.
You can also create your own local theme:
lib/impress_css/
files as a model to work from.themes
in the directory where your markdown
file is. Inside it put the [yourtheme].css
and [yourtheme].html
filesmdpress -s [yourtheme]
and mdpress will look for the two theme
files in themes/
matching that name.Someone emailed you a mdpress
presentation. Now you want to just run it? Sure:
mdpress -r [filename.md]
That will automatically compile the presentation and open it in a browser window.
mdpress now has Latex support through MathJax. To build your presentation with latex support, use the --latex
flag.
Put your latex code between a pair of $$
’s, like this:
# Latex!
$$e^{\imath\pi} = -1$$
Note: you might run into conflicts between markdown and latex. For example, _
means emphasize in markdown. So if you want subscripts, escape _
:
$a_x$ # wrong, x will be italic
$a\_x$ # right, x will be a subscript
Metadata can be set via YAML-Frontmatter. Have a look at the examples for further information. For example, if you want to set a title, put this at the top of the markdown file:
---
title: All about chicken
---
