"KiCad" is a collection of several programs, each with their own role in the PCB design process.
KiCad is designed around working on one project at a time, each PCB project is kept in it's own directory.
What is "schematic capture"? It's all about drawing the schematic (aka circuit diagram), which produces the netlist and BOM. The netlist is required for PCB layout, or can be used for running simulations in SPICE. More below.
UI involves using keyboard + mouse, you'll want to learn some of the keyboard shortcuts.
Wires can be connected to other wires (filled green circles) or unconnected pins (square/circle outlines).
General workflow is to move cursor to start of wire, press 'w' key, draw wire, pressing 'w' to add corners, then click a node or press 'k' to end the wire.
Where are pins 1 and 8? Some parts have pins that are hidden by default - see the "Show hidden pins" button on the left. Make sure a net has name "VCC" to provide power to these.
Once the diagram has all required parts, "Annotate" it to change reference designators from C? to C123.
Next, we need to associate the parts on the schematic with footprints for the PCB Layout tool. Run the CvPcb tool with the button at the top:
CvPcb shows three panes - the left pane is a list of parts libraries, the middle is the parts in your schematic, and the right is a list of parts that have passed through the current set of filters. Filters are enabled/disabled using the buttons at the top. Associate parts by highlighting your part in the middle, then double clicking the footprint on the right.
Once all the parts on your board are associated with footprints, click the "save" button and go back to Eeschema to export the netlist. Default settings should be fine for Pcbnew.
Pcbnew is the program where we do the actual circuit board layout. It takes a netlist from Eeschema and footprint information from the library, and helps you lay out a PCB.
PCBs dimensions are often discussed in mils, which is prounounced "terrible unit". A mil is \(\frac{1 inch}{1000}\), not a millimeter.
Things get especially fun with SMT package sizing eg 0603 Metric is equivalent to 0201 Imperial, about a third the size of the more common 0603 Imperial.
You'll find some parts fit nicely on mm grids, and some fit nicely on inch grids. So, don't get too caught up on one system or another - it's very easy to switch the grid as desired.
The first step using Pcbnew in a new project is importing the netlist from your earlier work in Eeschema. Click the "Read netlist" button to bring in your earlier work - it should be selected by default. You might get a few errors like these - we'll deal with them later:
Once your netlist is imported, all the parts will be stacked on top of each other - not very helpful. Make sure you're in "Footprint mode" , then right click in the black area and select "Global Spread and Place", then "Spread out All Footprints".
In my experience, PCB layout is an iterative process. This time, we know the maximum dimensions based on the PCB supplier - it's cheaper if we can stay inside 5x5 cm - so let's start making a board outline. Pick the Edge.Cuts layer on the right hand side, then select the "Add Graphic Line or Polygon".
While getting the outline right, you might find it helpful to right-click on sections of the "drawing" (the outline) with the drawing tool selected. For example, the arc tool will create 90° arcs by default, but those can be changed through the "Edit Drawing" context menu.
Unfortunately, there's an error in the netlist generated - the gate pin on this FET should be pin 1, but we've got it connected to pin 2... How to fix
Some of the track in this project will need to carry relatively high current, so we'll want to draw those a bit wider than default. Pcbnew uses a concept of "Net Classes" to set default widths, clearances, via sizes, etc. for nets. Net Classes are setup in Design Rules > Design Rules Editor.
For a simple board, make sure the clearance for the default net list looks reasonable, then go to the Global Design Rules tab and add some extra track width and via diameters.
The "add tracks and vias" tool lets you lay down wires. When you're drawing, the 'w' key changes width, and the 'v' key adds a via.
Although KiCad has a large libary of components available, we'll likely need to make some additions or changes. In doing this, it's important to understand the distinction between a Symbol and Footprint (formerly known as module).
I've found three approaches to footprint issues in KiCad:
PCB fab houses generally take "Gerbers" for everything except the "drill file", which uses Excellon format. Generate Gerbers from Pcbnew's file > Plot dialog.

It all started when Junior's dad Peter Andre posted a cute family video of himself playing an egg catching game with daughter Princess, as Junior danced in the background.
Someone commented on the post: "Junior is always bopping around, so funny!"
However, they added: "Nice to see what real families do and not what Katie does, which is use her kids to make the headlines! Sorry but had to be said."

Clearly keen to stick up for his mum, Junior – who is just 14 years old – replied to the troll who criticised his mum's parenting skills.
He said: "You don't need to post negative stuff about my mum."
Peter was clearly keen to stop things escalating and turned off the comments on his post.
Letting his eldest kids have social media accounts has long been a worry for Pete.
Recently someone impersonated Junior on Instagram and asked their followers to send him inappropriate pictures.

Katie, meanwhile, is on a mission to make online trolling a crime with the introduction of Harvey's Law.
She recently begged fans to "name and shame" the troll who had called her disabled son "fat".

domestic | environment | combustion appliances – protection from combustion products | 2005
Every
building
must be designed and
constructed
in such a way that
any component part of each fixed combustion appliance installation
used for the removal of combustion gases will withstand heat
generated as a result of its operation without any structural change
that would impair the stability or performance of the installation.
3.18.0 Introduction
The fire service attends many calls to
chimney
fires and other fires where a
this standard cannot prevent fires, the structural precautions recommended
help to limit the damage to
flues
and thus prevent fire from spreading into the
building
.
It is essential that
flues
continue to function effectively when in use without
flue-pipes
are now tested to harmonised European standards to establish
their characteristics relative to safe operation.
Very low
flue
-gas temperatures are achieved by modern, high efficiency
appliances, particularly during night conditions, thus causing condensation.
Materials need to withstand these aggressive situations.
Explanation of terms
The following terms are included to provide clarity to their meaning in this
Technical Handbook.
including any openings for the accommodation of a combustion appliance, but
does not include a
chimney
terminal;
combination of compatible
chimney
components that may be from 1 or
different sources;
Factory-made chimney
– see
system chimneys
;
Flue
– passage for conveying the products of combustion to the outside
atmosphere;
Flue liner
– wall of a
chimney
consisting of components the surface of which
is in contact with products of combustion;
Flue-pipe
– (correctly termed ‘connecting
flue-pipe’
) is a pipe, either single
walled (insulated or non-insulated) or double-walled, that connects a
combustion appliance to a
flue
in a chimney;
System chimneys
– (factory-made chimney)
chimney
that is installed using a
combination of compatible
chimney
components, obtained or specified from
one manufacturing source with product responsibility for the whole
chimney
.
Some of these terms are explained in greater depth later in the guidance to
this standard.
In the case of
conversions
, as specified in regulation 4, the
building
as
converted
shall meet the requirement of this standard (regulation 12,
schedule 6).

3.18.1 Chimneys generally
Combustion appliances are very often changed after the original installation.
Unless an appliance is supplied to be used with a specified
system chimney
sometimes more economical, to cater initially for the most severe conditions
as regards the danger of fire, generally a traditional open fire, and to ensure
that all components are compatible.
Combustion appliances, other than flueless appliances such as gas cookers,
withstand the heat generated by the normal operation of the appliance. A
chimney
of a higher specification than the designation strings given (see
clause 3.18.2) may be used if required, such as a
chimney
generally suitable
for use with an open-
flued
solid fuel appliance may be used with an open-
flued
gas-fired appliance.
The National Association of Chimney Engineers (NACE) was set up to
operation of a heating appliance. They provide a register of competent and
qualified
chimney
engineers for all types of
chimney work
. Advice is also
available from the British Flue and Chimney Manufacturers’ Association
(BFCMA). These organisations do not have a mandatory status.
Sweeping
chimneys
The process of burning will naturally cause deposits of soot in the
flue
.
Chimneys
and
flue-pipes
therefore should be swept at least annually if
smokeless solid fuel is burnt and more often if wood, peat and/or other high
volatile solid fuel such as bituminous coal is burnt. Mechanical sweeping with
a brush is the recommended method of cleaning.
Every
chimney
should have such capacity, be of a height and location and
with an outlet so located that the products of combustion are discharged
freely and will not present a fire hazard.
essentially uniform, gas-tight and resistant to corrosion from combustion
products.
Chimneys
should be
constructed
in accordance with:
a. the recommendations of BS 6461: Part 1: 1984 for masonry
chimneys
; or
b. the recommendations of BS 7566: Parts 1 - 4: 1992 for metal
system
chimneys
; or
c. BS 5410: Part 1: 1997 and OFTEC Technical Book 3, where serving an
oil-firing appliance; or
d. BS 5440: Part 1: 2000, where serving a gas-fired appliance.
3.18.2 Chimney designations
Designations for
chimneys
, according to BS EN 1443: 2003, are dependant
on the fuel to be used, the type of appliance and the operating conditions.
The designation string prescribes limiting values or categories for
temperature, pressure, condensate resistance, corrosion resistance, soot fire
resistance and distance to combustibles. Values for which the
chimney
is
suitable are specified by the
system chimney
manufacturer or the designer of
chimney
designation should be chosen to suit the intended appliance
installation. For an existing
chimney
the appliance performance should be
chosen to match the designation of the
chimney
. Advice on the appropriate
chimney
specification should be sought from the appliance manufacturer.
3.18.1
—
3.18.2
domestic | environment | combustion appliances – protection from combustion products | 2005
Solid fuel
The recommended designation for
chimneys
and
flue-pipes
for use with
natural draught, solid fuel appliances is T400 N2 D 3 Gxx.
The recommended designation for
chimneys
and
flue-pipes
for use with
forced draught solid fuel appliances that have a positive pressure at the
outlet of the appliance is T400 P2 D 3 Gxx.
The pressure designation P2 is regarded as the default specification.
However the
chimney
can often generate an adequate natural draught, so
that the appliance can be safely used with
chimneys
and
flue-pipes
with the
negative pressure designation even if the appliance is fanned. The draught
generated in a
chimney
may be calculated according to BS EN 13384-1:
2002. If there is any doubt, and/or unless the appliance manufacturer
specifies N2, the designation P2 should apply.

oil-firing appliances with a flue gas temperature not more than 250º C

Class D
T160 N2 W 2 Oxx
Note:
The pressure designation N2 is regarded as the most likely specification to
apply in the oil industry for both vaporising and pressure jet appliances. Most
pressure jet appliances only generate adequate pressure to overcome flow
resistance within the appliance so that the products of combustion entering the
chimney
will be at a negative pressure with respect to the atmosphere. Thus
the appliance can be safely used with
chimneys
and
flue-pipes
with negative
pressure designation. In the event that an appliance design produces a
positive pressure at the outlet of the appliance, it is the manufacturer’s
responsibility to inform the installer that a
chimney
with a positive designation
should be used. If there is any doubt, the more onerous designation P2 should
apply.
The appliance manufacturer’s instructions should always be checked. They
may specify a higher designation.

the
chimney
can often generate an adequate natural draught, so that the
appliance can be safely used with
chimneys
and
flue-pipes
with the negative
pressure designation even for many fanned draught gas appliances, including
condensing boilers that may otherwise have positive pressure at the outlet to
BS EN 13384-1: 2002. If there is any doubt, and/or unless the appliance
manufacturer specifies N2, the designation P2 should apply.
3.18.3 Masonry chimneys
outer wall of brick, block or stone, should be well
constructed
and in
corporate a
flue
liner, or
flue-blocks
, of either clay material or precast
concrete. A masonry
chimney
should be
constructed
in accordance with the
recommendations in BS 6461: Part 1: 1984. If an outer wall is
constructed
of
concrete it should be
constructed
in accordance with BS EN 12446: 2003.
It is a complex operation to upgrade the
chimney
at a later date to serve a
new appliance that needs a higher classification of
chimney
to operate safely,
thus a
chimney
designed for solid fuel will also serve for oil or gas. See
clause 3.18.6 for guidance on
flue
liners.
Chimneys
can also be
constructed
of prefabricated block components,
designed for quick
construction
.
Chimney
components such as cappings,
offsets and precast fireplace components are available with this type of
system. Some
flue-blocks
are specially designed for gas-fired appliances
only.
Flue-blocks
should be
constructed
and installed in accordance with
recommendations in:
a. BS EN 1858: 2003, for a precast concrete
flue-block chimney
;
b. BS EN 1806: 2000, for a clay
flue-block chimney
.
3.18.4 Metal chimneys
Metal
chimneys
may be either single-walled or double-walled. Each of these
types is commonly factory-made by one manufacturer as sets of components
for easy assembly on
site
(although they can be supplied as 1 unit) and is
thus a
system chimney
. A choice of fittings such as bends, brackets, and
terminals are available.
3.18.2
—
3.18.4
domestic | environment | combustion appliances – protection from combustion products | 2005
Some metal
chimneys
are specifically designed for use with gas-fired
appliances and should not be used for solid fuel appliances because of the
higher temperatures and greater corrosion risk.
Metal
system chimneys
, with the following designations, should be
constructed
in accordance with the recommendations in BS EN 1856-1:
a. T400 N1 D V3 (or Vm - Lxxxxx) Gxx, for solid fuel appliances;
b. T400 P2 D V3 (or Vm - Lxxxxx) Gxx where it serves an oil-firing appliance
producing a
flue
gas temperature of not more than 400º C, e.g. burning
Class D oil (gas oil);
c. T250 N2 D V2 (or Vm - Lxxxxx) Oxx where it serves an oil-firing appliance
producing a
flue
gas temperature of not more than 250º C, e.g. burning
Class C2 oil (kerosene);
d. T250 N2 D V1 (or Vm - Lxxxxx) Oxx where it serves a gas appliance.
Corrosion resistance
The corrosion resistance may be specified, according to BS EN 1856-1, by:
a. a corrosion test method, which leads to a value of either V1, V2 or V3; or
b. by a material specification code Vm - Lxxxxx where the first 2 digits
represent a material type as quoted in BS EN 1856-1, Table 4 and the last
3 digits represent the material thickness.
Acceptable material specifications may be taken from the national Annex to
BS EN 1856-1. For example, an acceptable material code for solid fuel, oil or
gas, would be Vm - L50040 representing a material type 50 with a thickness
of 0.40 mm.
A metal
chimney
should not pass through a

removable, imperforate casing. Also where the
chimney
passes through the
roof space
, such as an attic, it should be surrounded be a rigid mesh that will
prevent an 8 mm diameter sphere from passing.
There should be no joints within any wall, floor or ceiling that make accessing
the
chimney
for maintenance purposes difficult.
3.18.5 Flue-pipes
A
flue-pipe
should be of a material that will safely discharge the products of
combustion into the
flue
under all conditions that will be encountered. A
flue-pipe
serving a solid fuel appliance should be
non-combustible
and of a
material and
construction
capable of withstanding the effects of a
chimney
fire without any structural change that would impair the stability and
performance of the
flue-pipe
.

City of Tshwane hopes to restore bus services by Tuesday afternoon
by Kamva SomdyalaCity of Tshwane officials hope Tshwane Bus Services (TBS) will be back in operation by Tuesday afternoon - pending the outcome of negotiations, the City said in a statement.
"All Tshwane Bus Services will remain suspended until tomorrow afternoon [Tuesday], pending the outcome of the negotiations between the employer and labour," mayoral committee for transport Sheila Senkubunge said.
In a press release on Sunday, the City warned commuters the strike was "due to workers being unhappy with the pace at which the process of conducting benchmarking salaries is taking place".
Many commuters were left stranded due to Monday's protest, with Senkubunge issuing an apology "for the inconvenience caused by workers who responded to ongoing wage negotiations and its pending outcomes".
Further in the statement, Senkubunge asked that commuters should exercise patience.
"This [suspension of services] is done in the interests of ensuring safety for our customers and safeguarding the City's assets."
Senkubunge added commuters would be kept abreast of any developments "in due course".

Developer Quick Start
Use Nymi’s SDK to develop Nymi-enabled applications (NEAs) for use with the Nymi Band. The SDK includes the Nymi API (NAPI), and the Nymulator (Nymi Band Simulator) to test your code without the need for a physical Nymi Band.
The Nymi API 4.1 is provided as a dynamic library on Windows, and a framework installer on macOS. To demonstrate the functionality exposed through NAPI, we have provided a sample application (apy
), which demonstrates how to provision a Nymi Band, how to obtain cryptographic assets from a provisioned Nymi Band, and several other functions. The sample app is an NEA written in Python.
This Developer Quick Start walks you through the setup of the Python sample app, the initialization of NAPI, and the provisioning process. From there, you can investigate the provided code to explore the other functions.
Supported Platforms
The Nymi SDK 4.1 currently supports the following platforms:
| OS | Supported Versions | Required Hardware | Recommended Developer Tools |
|---|---|---|---|
| Apple Mac OS | OS X Yosemite (10.10) | Bluetooth® Low Energy 4.0 | Xcode 7.2.1 |
| OS X El Capitan (10.11) | Bluetooth® Smart Ready | ||
| macOS Sierra (10.12.2 or later) | |||
| Microsoft Windows | Windows 10, 8.1, 7 | BLED112 Bluetooth Smart Adapter | Visual Studio 2015 |
| 64 bit only | (required for, and included with, the Nymi Band) |
Contents of the SDK Package
The Nymi SDK package structure is as follows:
- (sdk4.1) .zip/.tar
- API
- Documentation
- NymiBluetoothService (Windows OS only)
- Nymulator
- LICENSE.txt
- Release Notes
Development with the Nymulator
You do not need a physical Nymi Band for NEA development. You can start developing immediately with the Nymulator, which simulates up to six Nymi Bands in a software environment.
The Nymulator is supported on the same OS X and Windows OS versions as the SDK.
The Development with a Nymi Band section describes the configuration changes required for running NAPI and the apy
sample app against a physical Nymi Band.
Developing on Windows Platforms
- Download the SDK zip. The link below is a direct download. All files are available on GitHub®.
- The Nymulator requires the Visual Studio Redistributable 2013 x86. If you do not already have the redistributable package installed, run
sdk4.1\Nymulator\vcredist_x86.exe
. - Clone or fork the
apy
sample app from theNymi/SampleApps/Python
GitHub repository. The link below opens in a new tab. - Copy the SDK zip file into the same directory as the sample app.
- Start the Nymulator. The Nymulator must be running before you start the sample app, otherwise NAPI cannot be properly initalized.
- Double-click the executable:
sdk4.1\Nymulator\Nymulator.exe
. - Make a note of the port number that the Nymulator is using. By default this is port
9088
. If this port is in use by another process, the Nymulator decrements the number and tries again until it finds an open port.
- Double-click the executable:
- Open a command window in the sample app directory.
- At the command prompt, type:
python go.py
. - When prompted, type
y
to allow the sample app to copy required files.
The sample app is designed to prompt you for missing information and provide feedback on options where applicable. For example, if you try to runpython go.py
before starting the Nymulator, the following information is printed to the command window:
Checking connectivity… done.
Failed to start, attempt: 1
Failed to start, attempt: 2
Failed to start, attempt: 3
Failed to start, attempt: 4
Failed to start, attempt: 5
Maybe check that the Nymulator is running. - In the Nymulator, click Add to create a virtual Nymi Band. When they are created, virtual Nymi Bands are authenticated, but not provisioned.
-
Provision the Nymi Band. Provisioning is a one-time process that establishes a trusted relationship between the Nymi Band and a specific NEA running on a specific device. The Nymi Band initiates the process by generating a pattern that appears on the Nymi Band’s LEDs. This pattern is also computed independently by NAPI and sent to the NEA. The user wearing the Nymi Band must confirm that the patterns match.
The pattern appears on the Nymi Band graphic in the upper-right corner of the Nymulator. At the same time, the pattern also appears in the command window, where a plus sign (+) indicates an LED is ON, and a minus sign (-) indicates an LED is OFF. If the two patterns match, you accept the pattern as described in this procedure.
- In the Nymulator, click Begin Provisioning. A pattern appears on the Nymi Band graphic.
- In the command window, the following message appears:
found a band to provision; pattern is
, followed by a series of 5 plus and/or minus signs - Confirm that the pattern in the command window matches the one displayed in the Nymulator.
- Type
y
to accept the pattern match.
Success messages appear in the command window, and in the Nymulator Activity Log.
Note: An NEA must have explicit user agreement to provision a Nymi Band. An NEA must provide some way for the user to confirm the LED pattern displayed on their Nymi Band. The NEA can either: display the pattern to the user, and ask for confirmation that the displayed pattern matches that on the band, or ask the user to input the pattern on their band, and proceed if it matches the pattern sent to the NEA by NAPI. The first approach is more convenient for the user, while the second provides greater certainty.
Now that the Nymi Band is provisioned, you can verify its authentication status, generate and obtain cryptographic assests, and more. These features are described in the NAPI JSON Examples section.
To start working with a physical Nymi Band, see the Development with a Nymi Band section, which describes the configuration changes required for running NAPI and the sample app against a physical Nymi Band.

Development with a Nymi Band
This section assumes that you have worked through the Development with the Nymulator section for your platform, and therefore you already have the SDK and sample app downloaded and configured. Remember that Nymi-enabled apps (NEAs) communicate only with authenticated Nymi Bands. Use the Nymi Band app to authenticate the Nymi Band before you use the sample app.
To work with a physical Nymi Band, follow the appropriate procedure below.

- Plug in the Bluetooth adapter (included in the box with your Nymi Band).
- Install and enable the Nymi Bluetooth Service (included in
sdk4.1\NymiBluetoothService\
). - Quit any running instances of
apy
. - Run
python go.py --real
. The--real
parameter tells the sample app to look for a Nymi Band instead of the Nymulator. - Tap the top sensor on your Nymi Band continuously until you see the provisioning pattern (that is, the lights flash in an outward pattern, from the center out to both sides). You can expect to see the pattern after four taps.
- Provision your Nymi Band.
- Confirm that the light pattern in the command window matches the one displayed on your Nymi Band.
- In the command window, type
y
.
For macOS / OS X:
- Shut down the Nymulator.
- Quit any running instances of
apy
. - Run
python go.py --real
. The--real
parameter tells the sample app to look for a Nymi Band instead of the Nymulator. - Tap the top sensor on your Nymi Band continuously until you see the provisioning pattern (that is, the lights flash in an outward pattern, from the center out to both sides). You can expect to see the pattern after four taps.
- Provision your Nymi Band.
- Confirm that the light pattern in the console matches the one displayed on your Nymi Band.
- In the console, type
y
.
Next Steps
- Explore the functions defined in
apy
, such asrun_gauntlet
, which demonstrates requesting a random number, and basic roaming authentication. - Review the NAPI Background Concepts
- Review the NAPI JSON reference pages, NAPI C++ Reference, or NAPI C Reference

You resize the browser and a smile creeps over your face. You’re happy: You think you are now mobile-friendly, that you have achieved your goals for the website. Let me be a bit forward before getting into the discussion: You are losing users and probably money if responsive web design is your entire goal and your only solution for mobile. The good news is that you can do it right.
We need to understand that, beyond any other goal, a mobile web experience must be lightning fast. Delivering a fast, usable and compatible experience to all mobile devices has always been a challenge, and it’s no different when you are implementing a responsive technique. Embracing performance from the beginning is easier.
“Most importantly, responsive web design isn’t intended to serve as a replacement for mobile web sites.” — Ethan Marcotte
Responsive web design is great, but it’s not a silver bullet. If it’s your only weapon for mobile, then a performance problem might be hindering your conversion rate. Around 11% of the websites are responsive, and the number is growing every month, so now is the time to talk about this.
According to Guy Podjarny’s research, 72% of responsive websites deliver the same number of bytes regardless of screen size, even on slow mobile network connections. Not all users will wait for your website to load.

While analyzing geospatial data, easy visualization is often needed that allows for quick plotting, and simple, but easy interactivity. Additionally, visualizing geospatial data in projected coordinates is also desirable. The 'quickmapr' package provides a simple method to visualize 'sp', 'sf' (via coercion to 'sp'), and 'raster' objects, allows for basic zooming, panning, identifying,labeling, selecting, and measuring spatial objects. Importantly, it does not require that the data be in geographic coordinates.

We were very happy to participate again in Google Summer of Code (GSoC), our third year, and specially to have been able to mentor eight fine students that successfully completed their projects. We thank them, and Google, for this extraordinary contribution to our R&D work.
Here is a brief highlight of this year's projects:
Robert ported the test suite to Lua using Busted, a Lua unit testing tool. His efforts improved not only our coverage, but most importantly, the portability of our tests: his new test suite, now merged into mainline LuaRocks, runs under continuous integration on both Linux, macOS and Windows. This was an extremely welcome addition, bringing much greater confidence to LuaRocks developers on avoiding portability regressions. Robert improved the checks in existing tests and wrote many new ones, including a new mock-server for testing the client API for uploading packages to the luarocks.org repository.
Typed Lua Typechecker - Tomasz Dyczek
Typed Lua is an optional type system that provides static type checking for the Lua language. Typed Lua extends the syntax of Lua 5.3 to introduce optional type annotations, and performs local type inference to detect more precise types for unannotated expressions.
During GSoC 2016, Tomasz implemented the core of Typed Lua in Haskell. Tomasz's implementation parses code written in a syntax close to the abstract syntax of Typed Lua and then type checks the generated AST. Besides providing a great support for testing and reasoning about new features before introducing them to Typed Lua, Tomasz's Haskell typechecker can be also used to validate tests to be included in Typed Lua's test suite.
During GSoC 2016, Kevin worked on the implementation of a class system for Typed Lua. He also added parametric polymorphism (generics) to Typed Lua, not only for classes, but also for existing Typed Lua types such as its functions and tables.
Kevin's work currently lives in its own branch, but will me merged in the main branch ASAP. Meanwhile, Kevin has written a detailed post explaining all the features that have been implemented
Improving Error Reporting in PEG Parsers - Matthew Allen Go
LPegLabel is an extension of LPeg, a pattern matching tool for Lua, based on Parsing Expression Grammars (PEGs). LPegLabel supports labeled failures, a facility that improves error reporting and recovery for PEG-based parsers.
The goal of this project was to use LPegLabel to write parsers with good error reporting. These parsers could then be used by the Lua community and also serve as a guide for LPegLabel users. Because LPegLabel is a young tool, another important expected contribution was to improve the tool's usability.
Matthew achieved both goals during GSoC 2016. First, he developed a Lua parser for Lua 5.3 based on LPegLabel. After GSoC 2016, Matthew's work has been incorporated into the new release of lua-parser (1.0.0), which is already available to the Lua community.
Matthew also contributed to LPegLabel's usability by improving its API and documentation.
Elasticsearch is a distributed and scalable search engine written in Java that, besides the transport protocol (Java to Java), offers a REST API accessed through JSON. During GSoC 2015, Dhaval implemented elasticsearch-lua, an initial client for the Lua language following a model similar to other existing clients, such as the clients written in Python and PHP.
During GSoC 2016, Dhaval worked on improving elasticsearch-lua. Apart from adding a test suite to elasticsearch-lua and making it robust, he also documented the entire codebase and updated the current client to be compatible with a newer version of Elasticsearch.
Dhaval exceeded our expectations by also creating a new library called luaver. This work was motivated by having to frequently switch between different versions of Lua while developing the test suite.
A full blog post about Dhaval's project during GSoC 2016 can be found here.
Admin Center and Elasticsearch integration for Sailor -
Nikhil Ramesh
Sailor is a web framework written in the Lua programming language and structured in a model-view-controller (MVC) architecture. Like other web development frameworks, such as Ruby on Rails and Django, it is designed to make the development process faster by making some assumptions and conventions (over configuration) and encouraging principles like DRY (Don't Repeat Yourself).
During GSoC 2016, Nikhil Ramesh focused on extending the Sailor framework by adding new features to it. The first feature he worked on was an Admin Center, which is initially being used as a web interface for editing the configuration of an application and accessing auto generation of scaffolding pages. Another part of his work consisted of integrating Sailor and elasticsearch-lua to facilitate Elasticsearch indexes to be stored as Sailor Models.
Nikhil's work is currently pending as a Pull Request, to be merged as soon as possible.
Extending the online tutorial of Céu with Emscripten and SDL - Margarit Vicentiu
Céu is a programming language that targets the development of reactive applications such as video games and embedded systems. Its compiler generates output in plain C to integrate easily with the the underlying platform (e.g. Arduino, SDL). For this project, we wanted to integrate Céu with Emscripten to also run applications in a web browser.
Vicentiu started with the online tutorial of Céu, which is a server-side application: the user types Céu code in a text area and hits the send button; the server receives the code, executes it, and sends the output back to the user. During the summer, Vicentiu made most of the examples compile with Emscripten and run in real-time in the user screen.
Our next goal is to make the graphical examples with user interactions also work in the browser, and Vicentiu plans to continue contributing to the project to achieve this goal.
An automatic generator of WSDL documents for LuaSOAP - Victor Dias
LuaSOAP is a library to ease the use of SOAP, the Simple Object Access Protocol. WSDL is an XML format for describing network services; it is used to describe operations, messages and types offered by Web Services.
This summer Victor extended LuaSOAP's support of WSDL by developing a software layer that helps automatic generation of WSDL documents. This new layer eases the description of most WSDL "bureaucracy" (types, operations, ports, messages...) with no counterpart in a dynamic language like Lua. He also improved the test suite and the documentation.
Victor's work will be integrated into LuaSOAP's next version.

LibTiff maintainers have started work on LibTiff 4.0, the next major upgrade of the time-proven TIFF codec. This upgrade will include support for the new BigTIFF file format. It is planned a preliminary version (LibTiff 4.0alpha1) will be operational by June 15, 2007. Testing and final release improvements for LibTiff 4.0 will be completed by July 30, 2007.
BigTIFF logically extends the original TIFF file format (referred to as 'ClassicTIFF' from now on), breaking the 4 gigabyte boundary, with 64bit offsets allowing files up to 18,000 petabytes in size. The BigTIFF specification is the result of work by a variety of parties on the LibTiff mailing list, including the current LibTiff maintainers, Joris Van Damme and Adobe staff. The BigTIFF specification has not yet been officially approved by the TIFF specification owner (Adobe), but implementation within LibTiff could accelerate that process. For more information on the BigTIFF file format, we recommend AWare Systems' BigTIFF page.
BigTIFF will be especially useful for people and vendors that are confronted with very large images, and still seek to use an open, simple, and extendable format. This requirement is frequently encountered in the geospatial field, but also concerns large format scanners, medical imaging and other fields.
The LibTiff BigTIFF upgrade is made possible by four sponsors funding the project. The programming work will primarily be done by Joris Van Damme (AWare Systems). LibTiff's licensing agreement will remain unchanged. More details on the project itself, are available from the BigTIFF in LibTiff project page.
The sponsors are, in alphabetical order:
