I did a webinar yesterday afternoon with Marc Siegel, Deb Wolf, and Ramsey Musallam on the various ways Flipped Learning can be incorporated into a science classroom. We spoke about changing mindsets, thinking about mastery learning and standards based grading, and using video tools in class along with other ideas and tips.
Ramsey spoke near the end of the broadcast about using inquiry learning in his Explore-Flip-Apply method. I asked him, “Ramsey, how do you train your kids to work well in an inquiry environment? I’m not sure mine could handle that from day one in the semester, so what do you do?”
Ramsey came back by saying, “Actually, I drop them right in from day one. I don’t really train them in anything at all. Kids have an innate curiosity that we have to tap into in order to fully engage them in the content.” (Or something along those lines.)
Now, let me preface this by saying I’ve heard Ramsey say this over and over as I’ve gotten to know him. But, I never really put any faith in my students.
I decided to take it to heart. Today, I had an entire lab planned out with procedures, data tables, and follow-up questions. I knew what my kids would do, and they would fill in the blanks and then move on. I decided to scrap the entire lab and go with one statement:
I have a sample. It has water attached to it. I need to know how much water it contains.
The only question I asked them for this lab is: “What percent of my sample is water?”
I didn’t have enough faith in my classes. I didn’t really trust them to do anything like this. I was proven wrong this morning. For you science folks, our average error from the first two classes is two percent. Two. My students have encouraged me, and from what I’ve observed, they’ve felt proud of their work. They were so excited to hear how close they had come. I haven’t seen energy like this in a while.
I’d lost sight of the excitement that should come from science…from discovery. I’d lost sight of the process because I’d focused too much on the end result. I can talk about the process, but I need to have them go through the process.
My students can now explain how to find the mass percentage of part of a compound. They can do it better than if I had stood up or recorded a video and taught them. Tomorrow, we’ll involve mols somehow and see what happens.
Hopefully, my students will begin to feel more trusted and more empowered in the process.

The quickest method of converting between JSON text and a .NET object is using the JsonSerializer. The JsonSerializer converts .NET objects into their JSON equivalent and back again.
For simple scenarios where you want to convert to and from a JSON string the SerializeObject and DeserializeObject methods on JsonConvert provide an easy to use wrapper over JsonSerializer.
Product product = new Product();
product.Name = "Apple";
product.Expiry = new DateTime(2008, 12, 28);
product.Price = 3.99M;
product.Sizes = new string[] { "Small", "Medium", "Large" };
string output = JsonConvert.SerializeObject(product);
//{
// "Name": "Apple",
// "Expiry": "\/Date(1230375600000+1300)\/",
// "Price": 3.99,
// "Sizes": [
// "Small",
// "Medium",
// "Large"
// ]
//}
Product deserializedProduct = JsonConvert.DeserializeObject<Product>(output);
SerializeObject and DeserializeObject both have overloads that take a JsonSerializerSettings object. JsonSerializerSettings lets you use many of the JsonSerializer settings listed below while still using the simple serialization methods.
JsonSerializer
For more control over how an object is serialized the JsonSerializer can be used directly. The JsonSerializer is able to read and write JSON text directly to a stream via JsonTextReader and JsonTextWriter. Other kinds of JsonWriters can also be used such as JTokenReader/JTokenWriter to convert your object to and from LINQ to JSON objects or BsonReader/BsonWriter to convert to and from BSON.
Product product = new Product();
product.Expiry = new DateTime(2008, 12, 28);
JsonSerializer serializer = new JsonSerializer();
serializer.Converters.Add(new JavaScriptDateTimeConverter());
serializer.NullValueHandling = NullValueHandling.Ignore;
using (StreamWriter sw = new StreamWriter(@"c:\json.txt"))
using (JsonWriter writer = new JsonTextWriter(sw))
{
serializer.Serialize(writer, product);
// {"Expiry":new Date(1230375600000),"Price":0}
}
JsonSerializer has a number of properties on it to customize how it serializes JSON. These can also be used with the methods on JsonConvert via the JsonSerializerSettings overloads.

I also had that impression. Checking out seems to be much slower than with
CVS. So I guess that's a server problem - we'll see if it gets better after
we've switched to our new server.

This paper introduces an architecture for generic constraint implementations based on variable views and range iterators. Views allow, for example, to scale, translate, and negate variables. The paper shows how to make constraint implementations generic and how to reuse a single generic implementation with different views for different constraints. A wide range of applications of views exemplifies their usefulness and their potential for simplifying constraint implementations. We introduce domain operations compatible with views based on range iterators. The paper evaluates the applicability of the approach as well as different implementation techniques for the presented architecture.

The Apprentice's Ryan-Mark reveals mystery man lying on floor wasn't him
The Apprentice’s Ryan-Mark Parsons has revealed that the mystery man lying on the floor of the boardroom was not him.
The womenswear consultant, who was the latest candidate to be fired from the show, has finally put the record straight – but it means we may never find out who the mystery man really was.
Ryan-Mark’s fellow candidate Thomas Skinner took to social media to joke that the man lying on the floor of the boardroom was the 19-year-old.
He originally tweeted: ‘People keep asking me who was the geeza laying on the floor under the table in last tasks boardroom! Well I can actually reveal it was @ryanmarkparsons.
‘Foot masseuse, the #Pig flys him in from Hamburg every Wednesday to keep his feet relaxed during the boardroom! #TheApprentice.’

But now our dreams are shattered because Ryan-Mark has confessed that it’s not actually him – and he doesn’t know the mystery man’s identity either.
He told Metro.co.uk: ‘I don’t know why people are accusing me of this, Thomas is stirring the pot, I have no idea who that was.
‘He was saying that it was me and that my foot masseuse had flown in to give me a massage but I can assure you it wasn’t me.’
Ryan-Mark, who was the youngest candidate on the show, continued to explain how despite this week’s task being a ‘disastrous’ one, he felt Lord Sugar’s decision to fire him was wrong.
‘Lord Sugar did not make the right decision, I shouldn’t have been fired,’ he explained.
‘If you look at Thomas, the only reason he was saved was because he decided to come back to the boardroom, I love Thomas but he has lost seven out of eight tasks and it was a disaster on his side.
‘Marianne is a naïve person on task, who runs around in her own universe.

‘And on task, she would be all over the place, she would be erratic and when it came to the boardroom she would attack you and be very condescending and patronising. She would really go for you.’
The Apprentice continues Wednesday at 9pm on BBC One.

Since some point in time it is possible to build Haproxy with a built-in Prometheus exporter. SMG does not need that and can use the native Haproxy “stats” end-point for monitoring.
I recommend exposing that on different than the default front-end port (and having it not accessible from the Internet), this is less important for “Internal” LBs which are not accessible from the Internet anyway.
Here is how the relevant haproxy.cfg section might look like:
frontend stats_frontend
bind *:8404
stats enable
stats uri /haproxy?stats
# stats refresh 60s
option dontlog-normal
This exposes the haproxy stats UI at the “http://%node_host%:8404/haproxy?stats” and the full stats would be accessible in CSV format at the “http://%node_host%:8404/haproxy?stats;csv” URL.
Once we are sure that Haproxy is configured to expose stats (by veryfying the above URLs) we are ready to configure SMG to monitor it.
The easiest way to achieve this is using the Autoconf plugin and the haproxy template. We will need the hostname and/or the IP address of where our Haproxy instance is listening - lets assume a hostname of haproxy1.host which can be resolved to an IP address using DNS.
We would create an autoconf target config file like this:
cat > /opt/smg/data/conf/autoconf.d/haproxy1.host-haproxy.yml <<-EOH
- output: haproxy1.host-haproxy-stats.yml
template: haproxy
node_name: haproxy1.host
runtime_data: true
runtime_data_timeout_sec: 15
command: "curl -sS -f 'http://haproxy1.host:8404/haproxy?stats;csv'"
context:
filter_rxx: stats_frontend
EOH
Then reload SMG conf as described here
This will tell the autoconf plugin to use the output of the curl command and the haproxy template to generate actual SMG configs to poll for these stats and update RRDs from the more important ones.
We also don’t want the stats from the actual stats end-point (if dedicated as suggested above) so we are filtering that out using the filter_rxx (“regex exclude”) value. Check the template source for additional properties which can be passed via the context property.
The new stats should be available in about a minute after a config reload whith the above snipped added.
This should be good-enough to monitor a single Haproxy host (or Virtual/HA IP) stats but in large scale setups one may want to use multiple (identical) LBs where the traffic is somehow distributed amongst them (e.g. via DNS Round Robin at the Edge layer). For such use cases SMG has the haproxy-agg template.
For example if we had one more haproxy instance identical with the above and named haproxy2.host, we would first add its own /opt/smg/data/conf/autoconf.d/haproxy2.host-haproxy.yml file similar to the above and then we would add the aggregate template, like this:
cat > /opt/smg/data/conf/autoconf.d/haproxy-agg-all.yml <<-EOH
- output: haproxy-all-agg.yml
template: haproxy-agg
node_name: haproxy-all
members: haproxy1.host,haproxy2.host
runtime_data: true
runtime_data_timeout_sec: 15
command: "curl -sS -f 'http://haproxy1.host:8404/haproxy?stats;csv'"
context:
filter_rxx: stats_frontend
EOH
Note that the aggregate template still uses a command like the individual hosts template, in this case it doesn’t matter against which of the members instances it would be executed since these are supposed to be identical.

Spree 1.2.0 introduces some fairly major changes in the basic architecture of Spree, as well as minor alterations and bugfixes.
Due to the long development cycle of Spree 1.2 in parallel with continuing development of the 1.1 branch, there may be features released in 1.2 that are already present in 1.1.
Summary
There were two major topics addressed within this release of Spree: custom authentication and better checkout customization.
The first was the ability to use Spree in conjunction with an application that already provided its own way to authenticate users. Due to how Spree was architected in the past, this was not as easy as it could have been. In this release of Spree, the auth component of Spree has been removed completely and placed into a separate extension called spree_auth_devise. If you wish to continue using this component of Spree, you will need to specify this extension as a dependency in your Gemfile. See Issue #1512 for more detail about the customization.
The checkout process has always been hard to customize within Spree, and that has generated complaints in the past. We are pleased to report in the 1.2 release of Spree that this has been substaintially easier with a new checkout DSL that allows you to re-define the checkout steps in a simple manner. For more information about this, please see Issue #1418 and Issue #1743.
Along with these two major issues, there were also a ton of minor improvements and bug fixes, explained in detail below.
Major changes (backwards incompatibility)
spree_auth removal
Authentication is disabled by default within Spree as of this release, with the application supposed to be providing its own authentication. If you are upgrading an existing Spree installation or just want it to work, you can achieve the behaviour of a 1.1 installation by adding “spree_auth_devise” to your Gemfile.
gem 'spree_auth_devise', git: "git://github.com/spree/spree_auth_devise"
For more information on how to customize authentication, please see the Authentication guide.
State machine customizations
Customizing the state machine within Spree now does not require you to override the entire state_machine definition within Spree’s Order model. Instead, you are provided with the ability to define the “next” events for Order objects like this:
Spree::Order.class_eval do checkout_flow do go_to_state :address go_to_state :delivery go_to_state :payment, if: lambda { payment_required? } go_to_state :confirm, if: lambda { confirmation_required? } go_to_state :complete remove_transition from: :delivery, to: :confirm end end
For more information about customizing the checkout process within Spree, please see the Checkout guide.
Minor changes
has_role?, api_key and roles methods now namespaced
On a usr object, the has_role? method is now called has_spree_role?, the api_key method is called spree_api_key and the roles association is now called spree_roles. This allows for applications to define their own has_role?, api_key and roles methods without them conflicting with the methods defined within Spree.
Introduce Spree::Product#master_images and Spree::Product#variant_images
Spree::Product#master_images and its alias Spree::Product#images only returns images belongs to master variant.
Spree::Product#variant_images behaviour is changed, it is no longer return only images belongs to master variants but now also include all variants’ images.
Spree::Zone#country_list renamed to #zone_member_list
Please be noted that the underlying logics remain intact.
Spree::Creditcard renamed to Spree::CreditCard
All occurences of Creditcard are changed to CreditCard to better follow Rails naming conventions.
Assert that ImageMagick is installed during Spree installation
When installing Spree, if the ImageMagick library was not installed on the system, then the identify command that Paperclip uses would fail and sample product images would not appear.
There is now a check in place to ensure that ImageMagick is installed before Spree is.
Sass variables can now be overriden
The variable definitions for the sass files of Spree have been moved to a separate file within Core called app/assets/stylesheets/store/variables.css.scss. You can override this file within your application in order to re-define the colors and other variables that Spree uses for its stylesheets.
Added support for serialized preferences

New UI for defining taxons and option types for a product
Rather than having the taxons and option types related to a product on two completely separate pages, they are now included on the product edit form. This functionality is provided by the Select2 JavaScript plugin, and will fall back to a typical select box if JavaScript is not available.
Using the Money gem to display currencies
In earlier versions of Spree, we used number_to_currency to display prices for products. This caused a problem when somebody selected a different I18n locale, as the prices would be displayed in their currency: 20 Japanese Yen, rather than 20 American Dollars, for instance.
To fix this problem, we’re now parsing the prices through the Money gem which will display prices consistently across all I18n locales. To now change the currency for your site, go to Admin, then Configuration, then General Settings. Changing the currency will only change the currency symbol across all prices of your store.
Note: After the 1.2.0 release, more options to format the currency output have been introduced. Specifically the position of the currency symbol which is fixed to :before in 1.2.0 can be adjusted. To achieve this in the 1.2.0, you may wish to override the Spree::Money.to_s function.

Packages consist of two main components:
● The package specification: This is the public interface, (these are the elements which can be referenced outside the package). We declare all database objects that are to be a part of our package within the specification.
● The package body: This contains the actual implementation of all the database objects declared within the package specification.
The package body implements the specifications in the package specification. It holds implementation details and private declarations which are invisible to the application. So we can debug, enhance or replace a package body without changing the specifications. Similarly we can change the body without recompiling the calling programs because the implementation details are invisible to the application.

Sneezing: to be avoided when game is shot
Title
Sneezing: to be avoided when game is shot
Collection
Summary
Sneezing to be avoided when game has been wounded. How to obviate the ill effect of a Sneeze. (L V.-21. 5654-5659). Mothers tell the children about how sneezing affects the death of game. Wounded game jumps up if the children sneeze.
Comments
1) Note on the inside of the front cover (Book V-21) pp.5629-5719 1/2. From 21 November to 15 December 1875, 2) See also The Moon, not to be looked at, when game is shot, for the first part of this story, as well as Destroying the sneeze or kkoroken, 3) pp.5654v & 5655v: sneezing on the hunting-ground is seen as a bad omen if it occurs first thing in the morning when hunters awake, 4) p.5657v: the action performed to suppress or 'rub away' a sneeze on the hunting-ground: the first finger of the right hand is put into the mouth, pulled out against the left cheek, making a noise; the right hand is then put over the nose and mouth and rubbed about – this ritual is called kkoroken, 5) p.5658v: people should destroy a sneeze by putting a hand over their nose, 6) This story is found in Book V-21

North Korea says it won’t give Trump a summit for free
LOS ANGELES: Several people were shot dead while watching a football game at a central California home on Sunday, police said.
Police were called to the scene after at least two people snuck into the backyard of a home in Fresno, around 200 miles (320 kilometers) north of Los Angeles, and opened fire.
“What we found were several individuals deceased in the backyard,” said Fresno police spokesman Bill Dooley.
Local media outlets reported that four people were killed. Police have not released a death toll but said nine people had been shot in the attack.
Dooley said police were looking for surveillance footage and witnesses to track the suspects.

Tiny
Tips
- Avalanche has a short delay before the stun connects, so try to slightly lead it if you can. You don't
need to go full Leshrac, but you're not going to hit someone who's running from the outskirts of the
AoE.
- Avalanche is constantly stunning in the AoE, so you can throw it in advance, like Ice Path, if you know
a hero will be in the AoE before it finishes (mid-banish, pre-TP).
- The Ava-toss combo works best if you use Toss slightly after Avalanche connects.
- Toss damages buildings if a unit lands on it.
- Toss breaks channels through spell immunity, including your allies'. Don't Toss your Sandy Claws until
he finishes channeling Epicenter.
- Toss always grabs the unit closest to Tiny.
- You can Toss people to runes.
- Let your right clicks finish. Tiny's attack speed is constantly changing throughout the course of the
game, which makes it a real pain to consistently cancel his backswing animation. Err on the side of
caution and be patient.
Counters
- As long as the rocks are flying around, an Avalanche will stun you if you walk into the AoE.
- Beware of being Tossed into Tiny's tower. Just because Avalanche is on CD or he doesn't have the mana for
both doesn't mean he can't kill you. If Tiny starts running towards you for no good reason, watch out.

- Tiny has no armor to start. Coupled with his super slow attack animation, Tiny can't trade hits very
well in lane.


Welcome to LLVM! In order to get started, you first need to know some basic information.
First, LLVM comes in two pieces. The first piece is the LLVM suite. This contains all of the tools, libraries, and header files needed to use the low level virtual machine. It contains an assembler, disassembler, bytecode analyzer, and bytecode optimizer. It also contains a test suite that can be used to test the LLVM tools and the GCC front end.
The second piece is the GCC front end. This component provides a version of GCC that compiles C and C++ code into LLVM bytecode. Currently, the GCC front end is a modified version of GCC 3.4 (we track the GCC 3.4 development). Once compiled into LLVM bytecode, a program can be manipulated with the LLVM tools from the LLVM suite.
Here's the short story for getting up and running quickly with LLVM:
Specify the full pathname of where the LLVM GCC frontend is installed.
Enable the SPEC2000 benchmarks for testing. The SPEC2000 benchmarks should be available in directory.
Consult the Getting Started with LLVM section for detailed information on configuring and compiling LLVM. See Setting Up Your Environment for tips that simplify working with the GCC front end and LLVM tools. Go to Program Layout to learn about the layout of the source code tree.
Before you begin to use the LLVM system, review the requirements given below. This may save you some trouble by knowing ahead of time what hardware and software you will need.
LLVM is known to work on the following platforms:
The LLVM suite may compile on other platforms, but it is not guaranteed to do so. If compilation is successful, the LLVM utilities should be able to assemble, disassemble, analyze, and optimize LLVM bytecode. Code generation should work as well, although the generated native code may not work on your platform.
The GCC front end is not very portable at the moment. If you want to get it to work on another platform, you can download a copy of the source and try to compile it on your platform.
Compiling LLVM requires that you have several software packages installed:
There are some additional tools that you may want to have when working with LLVM:
If you want to make changes to the configure scripts, you will need GNU autoconf (2.57 or higher), and consequently, GNU M4 (version 1.4 or higher). You will also need automake. Any old version of automake from 1.4p5 on should work; we only use aclocal from that package.
These are needed to use the LLVM test suite. Please note that newer versions of QMTest may not work with the LLVM test suite. QMTest 2.0.3 can be retrieved from the QMTest CVS repository using the following commands:
LLVM is very demanding of the host C++ compiler, and as such tends to expose bugs in the compiler. In particular, several versions of GCC crash when trying to compile LLVM. We routinely use GCC 3.3.3 and GCC 3.4.0 and have had success with them. Other versions of GCC will probably work as well. GCC versions listed here are known to not work. If you are using one of these versions, please try to upgrade your GCC to something more recent. If you run into a problem with a version of GCC not listed here, please let us know. Please use the "gcc -v" command to find out which version of GCC you are using.
GCC versions prior to 3.0: GCC 2.96.x and before had several problems in the STL that effectively prevent it from compiling LLVM.
GCC 3.3.2: This version of GCC suffered from a serious bug which causes it to crash in the "convert_from_eh_region_ranges_1" GCC function.
The remainder of this guide is meant to get you up and running with LLVM and to give you some basic information about the LLVM environment.
The later sections of this guide describe the general layout of the the LLVM source tree, a simple example using the LLVM tool chain, and links to find more information about LLVM or to get help via e-mail.
Throughout this manual, the following names are used to denote paths specific to the local system and working environment. These are not environment variables you need to set but just strings used in the rest of this document below. In any of the examples below, simply replace each of these names with the appropriate pathname on your local system. All these paths are absolute:
For the pre-built GCC front end binaries, the LLVMGCCDIR is cfrontend/platform/llvm-gcc.
In order to compile and use LLVM, you will need to set some environment variables. There are also some shell aliases which you may find useful. You can set these on the command line, or better yet, set them in your .cshrc or .profile.
If you have the LLVM distribution, you will need to unpack it before you can begin to compile it. LLVM is distributed as a set of two files: the LLVM suite and the LLVM GCC front end compiled for your platform. Each file is a TAR archive that is compressed with the gzip program.
The files are as follows:
If you have access to our CVS repository, you can get a fresh copy of the entire source code. All you need to do is check it out from CVS as follows:
This will create an 'llvm' directory in the current directory and fully populate it with the LLVM source code, Makefiles, test directories, and local copies of documentation files.
If you want to get a specific release (as opposed to the most recent revision), you can specify a label. The following releases have the following label:
If you would like to get the GCC front end source code, you can also get it from the CVS repository:
cvs -z3 -d :pserver:anon@llvm-cvs.cs.uiuc.edu:/var/cvs/llvm co llvm-gcc
Please note that you must follow these instructions to successfully build the LLVM C front-end.
If the main CVS server is overloaded or inaccessible, you can try one of these user-hosted mirrors:
Before configuring and compiling the LLVM suite, you need to extract the LLVM GCC front end from the binary distribution. It is used for building the bytecode libraries later used by the GCC front end for linking programs, and its location must be specified when the LLVM suite is configured.
To install the GCC front end, do the following:
If you are using Solaris/Sparc or MacOS X/PPC, you will need to fix the header files:
cd cfrontend/platform
./fixheaders
The binary versions of the GCC front end may not suit all of your needs. For example, the binary distribution may include an old version of a system header file, not "fix" a header file that needs to be fixed for GCC, or it may be linked with libraries not available on your system.
In cases like these, you may want to try building the GCC front end from source. This is not for the faint of heart, so be forewarned.
Once checked out from the CVS repository, the LLVM suite source code must be configured via the configure script. This script sets variables in llvm/Makefile.config and llvm/include/Config/config.h. It also populates OBJ_ROOT with the Makefiles needed to begin building LLVM.
The following environment variables are used by the configure script to configure the build system:
| Variable | Purpose |
|---|---|
| CC | Tells configure which C compiler to use. By default, configure will look for the first GCC C compiler in PATH. Use this variable to override configure's default behavior. |
| CXX | Tells configure which C++ compiler to use. By default, configure will look for the first GCC C++ compiler in PATH. Use this variable to override configure's default behavior. |
The following options can be used to set or enable LLVM specific options:
To configure LLVM, follow these steps:
In addition to running configure, you must set the LLVM_LIB_SEARCH_PATH environment variable in your startup scripts. This environment variable is used to locate "system" libraries like "-lc" and "-lm" when linking. This variable should be set to the absolute path of the bytecode-libs subdirectory of the GCC front end, or LLVMGCCDIR/bytecode-libs. For example, one might set LLVM_LIB_SEARCH_PATH to /home/vadve/lattner/local/x86/llvm-gcc/bytecode-libs for the x86 version of the GCC front end on our research machines.
Once you have configured LLVM, you can build it. There are three types of builds:
Once you have LLVM configured, you can build it by entering the OBJ_ROOT directory and issuing the following command:
gmake
If the build fails, please check here to see if you are using a known broken version of GCC to compile LLVM with.
If you have multiple processors in your machine, you may wish to use some of the parallel build options provided by GNU Make. For example, you could use the command:
gmake -j2
There are several special targets which are useful when working with the LLVM source code:
It is also possible to override default values from configure by declaring variables on the command line. The following are some examples:
Every directory in the LLVM object tree includes a Makefile to build it and any subdirectories that it contains. Entering any directory inside the LLVM object tree and typing gmake should rebuild anything in or below that directory that is out of date.
The LLVM build system is capable of sharing a single LLVM source tree among several LLVM builds. Hence, it is possible to build LLVM for several different platforms or configurations using the same source tree.
This is accomplished in the typical autoconf manner:
Change directory to where the LLVM object files should live:
cd OBJ_ROOT
Run the configure script found in the LLVM source directory:
SRC_ROOT/configure
The LLVM build will place files underneath OBJ_ROOT in directories named after the build type:
If you're running on a linux system that supports the "binfmt_misc" module, and you have root access on the system, you can set your system up to execute LLVM bytecode files directly. To do this, use commands like this (the first command may not be required if you are already using the module):
$ mount -t binfmt_misc none /proc/sys/fs/binfmt_misc $ echo ':llvm:M::llvm::/path/to/lli:' > /proc/sys/fs/binfmt_misc/register $ chmod u+x hello.bc (if needed) $ ./hello.bc
This allows you to execute LLVM bytecode files directly. Thanks to Jack Cummings for pointing this out!
One useful source of information about the LLVM source base is the LLVM doxygen documentation available at http://llvm.cs.uiuc.edu/doxygen/. The following is a brief introduction to code layout:
Every directory checked out of CVS will contain a CVS directory; for the most part these can just be ignored.
This directory contains public header files exported from the LLVM library. The three main subdirectories of this directory are:
This directory contains most of the source files of the LLVM system. In LLVM, almost all code exists in libraries, making it very easy to share code among the different tools.
This directory contains libraries which are compiled into LLVM bytecode and used when linking programs with the GCC front end. Most of these libraries are skeleton versions of real libraries; for example, libc is a stripped down version of glibc.
Unlike the rest of the LLVM suite, this directory needs the LLVM GCC front end to compile.
This directory contains regression tests and source code that is used to test the LLVM infrastructure.
The tools directory contains the executables built out of the libraries above, which form the main part of the user interface. You can always get help for a tool by typing tool_name --help. The following is a brief introduction to the most important tools:
- gccas
- This tool is invoked by the llvmgcc frontend as the "assembler" part of the compiler. This tool actually assembles LLVM assembly to LLVM bytecode, performs a variety of optimizations, and outputs LLVM bytecode. Thus when you invoke llvmgcc -c x.c -o x.o, you are causing gccas to be run, which writes the x.o file (which is an LLVM bytecode file that can be disassembled or manipulated just like any other bytecode file). The command line interface to gccas is designed to be as close as possible to the system `as' utility so that the gcc frontend itself did not have to be modified to interface to a "weird" assembler.
- gccld
- gccld links together several LLVM bytecode files into one bytecode file and does some optimization. It is the linker invoked by the GCC frontend when multiple .o files need to be linked together. Like gccas, the command line interface of gccld is designed to match the system linker, to aid interfacing with the GCC frontend.
This directory contains utilities for working with LLVM source code, and some of the utilities are actually required as part of the build process because they are code generators for parts of LLVM infrastructure.
#include <stdio.h> int main() { printf("hello world\n"); return 0; }
Next, compile the C file into a LLVM bytecode file:
% llvmgcc hello.c -o hello
Note that you should have already built the tools and they have to be in your path, at least gccas and gccld.
This will create two result files: hello and hello.bc. The hello.bc is the LLVM bytecode that corresponds the the compiled program and the library facilities that it required. hello is a simple shell script that runs the bytecode file with lli, making the result directly executable. Note that all LLVM optimizations are enabled by default, so there is no need for a "-O3" switch.
Run the program. To make sure the program ran, execute one of the following commands:
% ./hello
or
% lli hello.bc
Use the llvm-dis utility to take a look at the LLVM assembly code:
% llvm-dis < hello.bc | less
Compile the program to native assembly using the LLC code generator:
% llc hello.bc -o hello.s
Assemble the native assembly language file into a program:
Solaris:% /opt/SUNWspro/bin/cc -xarch=v9 hello.s -o hello.native
Others:% gcc hello.s -o hello.native
Execute the native code program:
% ./hello.native

A couple months ago my sweetie and me did 2ct7. we both did 10mg nasally -- in part to make 20mg go farther, and in part because the very slow come-on of doing it orally sounded, well, very slow.
Within 10 mins of doing it, the effects were strong, and they just got stronger. For about 30 mins we were both incapacitated and uncomfortable. there were many swirling colors and a strong, odd body-ache. It seemed best to be lying down, but even that didn't feel too good. it was very trippy, but there was a strong component of 'oh god, I hope this stops soon'. there was some nausea; more for me, having just eaten beforehand, and i got sick, about 30-40mins into it. After that I felt a bit better, and a good friend asked me to go for a walk. walking around cleared my head a lot. there was still a fairly overwhelming *woosh* of disorientation and color. I was kinda stunned. It was hard to talk or follow what was happening.
After about an hour, it became more pleasant. The 'too much' feeling passed, leaving a colorful, trippy space. I still felt pretty unable to interact with people. I had been planning to add mdma at some point, and other people present had already started on mdma, so I took 100mg mdma around 2 hours into the 2ct7. By that point, the 2ct7 had definitely passed peak and was settling into a colorful trippy glow.
In combination with the mdma, the rest of the night was somewhat like a combination of mdma and 2cb. The mdma perked me up, while the 2ct7 kept things trippy, sort of 'washed out', and colorful. I boosted the mdma after a couple hours, and came down from both mdma and 2ct7 more or less in sync.
So 10mg of 2ct7 nasally, for me, came on fast, reached peak in about 30-45 mins, in the middle of about 30-45 mins of 'make it stop' unpleasantness. After the first hour or so, there was a long slow pleasant decline, reaching baseline, more or less, about 6 or 7 hours later.
If I were to do it nasally again, I might try doing 5mg, waiting 30 mins or so and doing another 5, to hopefully make the first hour more bearable. I also would not eat beforehand. nasally, it burned slightly and tasted yucky, but wasn't too bad.

The steps below are for a VNET jail.
There are two options to get Internet connectivity for jails:
NAT is probably the easiest method for most cases.
Follow these steps to get Internet connectivity inside a jail with NAT (handled in PF):
net.inet.ip.forwarding=1 # Enable IP forwarding between interfaces
net.link.bridge.pfil_onlyip=0 # Only pass IP packets when pfil is enabled
net.link.bridge.pfil_bridge=0 # Packet filter on the bridge interface
net.link.bridge.pfil_member=0 # Packet filter on the member interface
Assign an IP to your bridge0 ifconfig <IP_ADDRESS>/24 up (this will become the default GW for the jail)
Add your physical interface (example em0) to bridge0 ifconfig bridge0 addm em0 up
Configure jail Interfaces ifconfig vnet0 <IP_ADDRESS>/24 up
nameserver <IP_ADDRESS>
nameserver <IP_ADDRESS>
Exit from chroot
Configure outbound NAT (“Real world example with VNET, NAT, PF, IPFW and port forwarding”)
Start jail iocage start UUID
Drop into jail iocage console UUID
ping default gateway <IP_ADDRESS>, you should have a reply!
ping Internet addresses, if all is good you should have Internet access now!

Let’s Hash It Out!
Arrays vs. hashes
December 4, 2014
This week we took a look at using arrays and hashes. These are both techniques for creating lists in Ruby, but they are used in different circumstances.
Arrays
An array is an ordered list of objects. Each object is linked to its position within the list in numerical order (starting with ‘0’). You can apply a method (action) to an array to do things like sort the list (.sort) or reverse the order (.reverse), and you can also access specific objects from your list by referencing their positions in the list. Arrays are great if you’re planning on manipulating the objects in the list in some way.
Let’s say you wanted to work with a list the characters in the movie “Frozen”.
frozen = [‘Elsa’, ‘Anna’, ‘Olaf’, ‘Kristoff’, ‘Hans’, ‘Sven’]You could apply methods to count the number of characters listed (frozen.count), alphabetize the characters (frozen.sort), find the first character listed (frozen.first), and so on. (Click here to view additional array methods.)
Hashes
A hash is a list of key and value pairs, with both the key and the value being objects. Just as an object in an array can be accessed using its numerical position, a value can be accessed within a hash using its key. Hashes are sometimes likened to dictionaries, since the values (definitions) can be found if you know the correct key (dictionary entry) to look up. Hashes allow you to store more information than an array would, and even allows you to list an array as a value.
Let’s create a hash for “Frozen” that includes more than just the list of characters.
frozen = { characters => [‘Elsa’, ‘Anna’, ‘Olaf’, ‘Kristoff’, ‘Hans’, ‘Sven’] genre => “animation” released => 2013 runtime => “102 min” rating => “PG” setting => “Arendelle” songs => [“Let It Go”, “Do You Want to Build a Snowman?”, “For the First Time in Forever”, “Fixer Upper”] }Now you can lookup the movie’s rating (frozen[rating]) and figure out if a song is included as a value (frozen.has_value? (“Fixer Upper”)), as well as taking more complex actions (click here for more examples).

- "Local particles in QFT"
- The goal of defining localized quanta and their
localization properties in quantum field theory has generated a large
debate ultimately leading to the far reaching question of whether QFT
describes particles or not. The sharpest criteria for localization is
that any state that is strictly localized within some region V of space
should produce the same expectation value as the vacuum state for any
local operator O(x) with x outside V.
Actually, it is impossible to construct such localized states using Fock states with any finite number of particles. Hence, the Fock states of QFT cannot be taken to represent particle states if we want them to be localized within some region of space.
In this talk we start from the existence of inequivalent representations of the algebra of observables in field theory to construct particle states satisfying localization properties and interpret them in terms of the standard Fock space states. - T.C. Farrelly (DAMTP Center for Mathematical Sciences, Cambridge, UK)
- "Discrete Spacetime and Relativistic Quantum Particles"
- Take a single quantum particle in discrete spacetime evolving in a causal way. We will see that in the continuum limit any massless particle with a two dimensional internal degree of freedom obeys the Weyl equation, provided that we perform a simple relabeling of the coordinate axes or demand rotational symmetry in the continuum limit. It is surprising that this occurs regardless of the specific details of the evolution: it would be natural to assume that discrete evolutions giving rise to relativistic dynamics in the continuum limit would be very special cases. We will also see that the same is not true for particles with larger internal degrees of freedom, by looking at an example with a three dimensional internal degree of freedom that is not relativistic in the continuum limit.
- Asif Shakeel (Haverford College, Haverford, PA, USA)
- "When is a Quantum Cellular Automaton a Quantum Lattice Gas Automaton?"
-
Quantum cellular automata (QCA) are models of quantum computation of particular interest from the point of view of quantum simulation. Quantum lattice gas automata (QLGA - equivalently partitioned quantum cellular automata) represent an interesting subclass of QCA. QLGA have been more deeply analyzed than QCA, whereas general QCA are likely to capture a wider range of quantum behavior. Discriminating between QLGA and QCA is therefore an important question. In spite of much prior work, classifying which QCA are QLGA has remained an open problem. We establish necessary and sufficient conditions for unbounded, finite QCA (finitely many active cells in a quiescent background) to be QLGA.

- "Cooling of Quark-Gluon Plasma and Electronic Turbulence in Graphene: A Relativistic Lattice Kinetic Approach"
- Recently, relativistic kinetic theory has attracted considerable interest to study multiple phenomena in relativistic fluid dynamics due to the fact that the relativistic Navier-Stokes equations are, for many problems in astrophysics and high-energy physics, unstable. The lattice Boltzmann method (LBM) is based on the solution of a minimal Boltzmann kinetic equation rather than on the discretization of the equations of continuum fluid mechanics, and has been used as an alternative computational fluid dynamics method. In this talk, an LBM for relativistic fluids is presented and applied to different phenomena. We provide numerical evidence that the Richtmyer-Meshkov (RM) instability contributes to the cooling of the quark-gluon plasma, shortening its lifetime. In addition, we also show that electronic turbulent phenomena in graphene could be observed, under current experimental conditions, through current fluctuations, echoing the detachment of vortices past localized micron-sized impurities.

- " Discrete time quantum walks: wave propagation and diffusive transport "
- I will focus on discrete time
quantum walks defined in one or two space dimensions, with a quantum
coin living in a two-dimensional Hilbert space. The walk is then
entirely defined by an operator in U(2) which depends
on 4 angles, and these are allowed to depend on both time and space.
I will first revisit the continuous limits of these walks. A systematic and mathematically rigorous limiting procedure will be introduced. It will be shown that the continuous limit, in most cases where it exists, is represented by a Dirac equation. The space-time dependence of the angles defining the walks transcribes into a coupling between the Dirac fermion and artificial gauge fields i.e. artificial electric, magnetic and gravitational field. This result opens up the possibility of performing laboratory experiments simulating relativistic charged spin 1/2 particles in arbitrary electromagnetic and
gravitational fields.
The second part of the talk will be devoted to quantum walks loosing quantum coherence because at least one of the angles defining the walk is chosen randomly at each time step. I will present analytical and numerical results on how these walks become classical as they lose coherence and are best approximated, in classical terms, by relativistic stochastic or diffusion processes.
The talk will end by my listing several open problems suggested by these results, highlighting in particular connections between quantum walks and geometry.

- "Exploration and Diffusion in Graphs using Deterministic Walks"
- In a continuous diffusive process, a certain amount of a resource, known
as "load", is initially placed on the nodes of the graph, possibly in
an unfair manner. In successive time steps, each node shares its load
evenly among all its neighbors, until the load on the nodes of the graph
eventually converges to its limit distribution (e.g., becomes uniform
in the case of regular graphs). However, continuous diffusion cannot be
applied to "granular load" which is not arbitrarily divisible, i.e.,
represented by unsplittable unit-load tokens (chips), which are placed
on nodes and may be passed around the graph. In such a scenario, one
natural way of simulating the continuous diffusion process is to require
that each chip follows an independent random walk on the graph.
In this talk, we will instead focus on chip diffusion processes following rules which are both locally fair and deterministic. These rules include the so-called "rotor walk", in which chips are propagated by each node to its neighbors in round-robin fashion and, more broadly, rules in which each node attempts to send out roughly the same number of tokens through each of its outgoing arcs.- - Alessandro Tosini (Università di Pavia, Pavia, Italy)
- ""The Fermionic Quantum theory"
- In the last three decades the relation between fermions and quantum systems has been largely investigated both from the computational and from the physical point of view. We consider the problem taking fermionic modes as the elementary systems of an operational probabilistic theory. Assuming maps involving fields on a number of fermionic modes to be local on that modes (local here is intended in the operational sense with maps on different systems commuting) we derive the Wigner parity superselection rule. Within this perspective the probabilistic theory of fermionic modes, denoted Fermionic Quantum theory, can be regarded as the parity superselected version of the Quantum Theory of qubits where superpositions of states having an even and an odd particle number are forbidden. As a consequence of the parity superselection the Fermionic Quantum theory lacks two fundamental traits of Quantum Theory: the local discriminability of states and the monogamy of the entanglement.

Scott Barron has really had his soul stirred by SwitchTower, apparently.
SwitchTower haiku, anyone?


Creates a 256*256 PNG image with overlayed markers for use on GTileOverlay layers in Google Maps.
| Keyword | Description |
|---|---|
| zoom | Zoom level of the Google Map (should be set automatically by the Google Maps API) |
| x, y | X and Y coordinates of the tile image. |
| image | The starting image that will get printed to |
| queryset | The queryset that will be filtered down to the lat/long bounds |
| hard_limit | Maximum number of points that will be printed on each image |
| icon | Path to the icon that will be used to denote each location |
| fields | The name of the lat/long fields in the model. Must be ``FloatField``s |
| field | The same as fields except a single PointField (part of GeoDjango) instead of FloatField |
All points are placed on the image, and then that image is returned.
| Keyword | Description |
|---|---|
| debug | If set to True, some debug information will be outputted to the image, and a red box will be printed around each image. |
| expand | If set to false, the queryset bounding filter will not be expanded, so any icons placed near the edge of the image will get cut-off. Useful for getting the exact number of items that are in the bounding box. |
| shuffle | If set to False, the queryset will not be shuffled. Shuffling occurs by adding “.order_by(‘?’)” to the end of the queryset. This helps minimize odd overlapping effects that occur sometimes. Different databases handle this shuffling technique, so it can be a performance issue. |
| just_queryset | If set to True, returns just the queryset of object without placing them into the image. |
