A program to calculate optimized bicycle tire pressure based on research that found a small sag or droop in the profile of the tire, led to better performance and comfort.
Imagine that you could ride one gear faster or feel less fatigued at the end of your ride and it cost you nothing. Tuning your bike tire pressure to your own unique situation may do just that. There are now 2 independent studies that support lower pressures are significantly better than pumping up your tires until they are rock hard. It all depends on wider bike tires with flexible sidewalls. Riding one gear higher, depending on your gearing, is a 5 - 8% increase.
The first step is evaluating whether your tires have flexible sidewalls which will respond readily to tire pressure changes. Tires marketed as racing tires, marketed as having a casing from a tubular tire, used by professional racers, or are a folding tire are good candidates. On the other hand, puncture resistant tires, snow tires, and thick touring tires are supported by their sidewalls and do not respond to pressure changes very well.
The simplest way to calculate your tire pressure is to use the companion web app, which uses this package.
To calculate your tire pressures, execute this code sequence:
my_bike <- bike_tire_pressures() # Supply your values for the parameters plot_bike_inflation(bike = my_bike)
If a test ride indicates that the tire pressure is really too low, it's likely your pressure gauge is reading too high. Try increasing your pressure by 10psi. Remember this is not an exact science nor setting so some experimentation may be needed.
Extra light casings need an extra 10-15% pressure to prevent the casing threads from breaking.
Suppose your trials indicate a performance improvement and you'd like to explore other tire options, or it's simply time for new tires. A wider tire is a great option to consider. The following code compares 2 setups and builds upon the first example.
new_tires <- bike_tire_pressures() # Supply new tires for the parameters plot_2_bike_inflation(bike_a = my_bike, bike_b = new_tires)
Bikes are for transporting gear around, but where your gear is attached will impact bike handling. Increasing load weight decreases handling stability. While your bike weight remains constant, your cargo weight could vary from 0 to 20lbs and that will change tire pressure quite a bit.
Calculating how your load is distributed between both wheels depends on factors unique to each bike that it is best to measure them. We can generalize about standard configurations and the following example will highlight the limitations.
Example coming soon!
If the rider is carrying a bike lock or backpack, their weight should be added to the rider weight, not the load weight.
It's unwise to assume a front/rear weight distribution when there are loads
on both the front and rear racks. My recommendation is to measure the
distribution on a level surface. Place a bathroom scale under one wheel
and a spacer block, the same height as the scale, under the other
wheel. Load up the bike, hop on, and have a helper steady you and read the
numbers. Flip the bike around and measure the other wheel. Divide the front
weight by the rear weight and use that for the front_distribution
parameter.
The original research was conducted when internal widths for road rims were around 19mm. Today's rims are available in wider sizes, 23 - 25mm, increasing the volume up to 33%. For these rims, measure the tire width with a digital or analog caliper and use that value for the tire width parameters.
Built-in pump gauges are inaccurate. Between a wide tolerance range of the pressure-sensing mechanism and imprecise reading of the gauge needle due to parallex, the indicated pressure should be considered an approximation.
A simple experiment can help determine how your pump is reading. Inflate your tires to the calculated pressure plus another 15psi. If a test ride seems harsher or your bike bounces around more, the pressure is too high. Repeat, but this time inflate to 15psi less than the calculated pressure. If your wheels bottom out or the handling is squirmy, the pressure is too low. Adjust in increments of 5psi and repeat until satisfied.
For road tubeless setups, exceeding 60psi seems to increase the likelihood of a tire blowoff as nicely summarized in this post.
Under development...
If using an inner tube, inflate it so it barely holds its shape and lightly coat with talc (talcum power). Then sprinkle some talc on the inside of the tire casing to coat the entire surface. Flip the tire inside out if you find it's easier to apply that way. This proceedure is mandatory for latex and light weight butyl tubes.
Then follow Sven Cycles marvelous instructions.
Under development...
At the end of the day, these two are effectively the same. That said, Weight is used for the individual components that go into the calculations. Load is used to describe the forces the tires are subject to.

Biking riding is an inherently risky activity. Remember the bike racer's motto: Falling is a matter of 'when', not 'if'. You are solely responsible for not exceeding any limits including, but not exclusive of your abilities, maximum tire inflation pressure, rim inflation pressure, mininum tire clearance, and compatibility of tubeless tire and rim combinations.

Convert polylines to continuous tubes using scalar data to scale and colour the generated tubes.
module BlendyTubesCore <src_file="blendytubes.cxx", libdeps="FLD", cxx_hdr_files="fld/Xfld.h"> { Mesh+Node_Data+read+notify+req+IPort2 &lines_in; TubesParams+IPort2 ¶ms; float+read+notify+req scale => .params.scale; boolean+read+notify+req offsetScale => .params.offsetScale; boolean+read+notify+req invertScale => .params.invertScale; int+read+notify+req facets => .params.facets; cxxmethod+notify_inst+req update; Mesh+Node_Data+write+OPort2 tubes_out; };
This module takes a Polyline cell_set with at least one scalar node_data component and creates a continuous tube for each polyline. For each node in the polyline a circular cross section is created and oriented in the direction of the polyline at that node. If two node_data components are present the second node_data component is used to proportionally scale each circular cross section. The scale parameters allows control over the overall width of the tube. The first node_data component is mapped appropriately to each node of the cross section. This results in colour mapped tubes that optionally vary in width according to the two separate node data components.
The module is designed to be used in conjunction with the DVinterp_data module to generate the node_data at each node of the polylines. The Tubes user macro does this. It is expected that the input polyline mesh will be generated by the Streamlines module, however other sources of polylines can be used. For instance the isoline module generates data with a Line cell set. By using the Isoline2Polyline module the data output by the isoline module can be used as the input to BlendyTubesCore module. An example of doing this is provided with the Isoline2Polyline project.
&lines_in
Input field data that contains a mesh with a cell_set of Polyline type and at least one scalar node_data components. The first node data component will be used to colour map the tube sections. If a second node data component is present it will be used to scale each section. Any other node data components will be ignored. The node_data can be of any scalar data type.
&TubesParams
A reference to the parameter block that contains the actual values of the module parameters.
scale
An overall scaling value that will be applied to each section of the tube. This parameter is always used and is not dependent upon whether scaling node data is present or not.
offsetScale
If the scaling node data component contains negative values and offsetScale is true then the scaling values will be shifted so they are all positive starting from zero. If offsetScale is false negative values will cause the tubes to turn themselves 'inside-out'. This parameter is ignored if no scaling node data is present.
invertScale
If invertScale is true then the scale component values will be inverted, hence larger values will produce narrower tubes and versa-versa. The scale parameter will still work as before as this overall scaling is applied after the data component scaling. This parameter is ignored if no scaling node data is present.
facets
The number of sides each tube will have. This parameter cannot be less than 3.
tubes_out
The generated field data containing a Mesh with Quad cell_set that forms the tubes and one scalar node data component that should be used for colour mapping the tubes.
The low-level BlendyTubesCore module is used in the TubesFunc functional macro. This macro is in turn used by the Tubes user macro.
Two example applications are provided for this project. The BlendyTubesEg application reads the 'bluntfin data set and generates a series of streamlines to visualize the air flow. The tubes macro is then used to generate a series of colour and size mapped tubes around each streamline. The SimpleTubesEg application similarly read the 'bluntfin data set. However it only generates a series of colour mapped tubes around each streamline.
xp_comm_proj/tubes/tubesmods.v contains the V definitions of the BlendyTubesCore low-level module and the TubesParams parameter block.
xp_comm_proj/tubes/tubesmacs.v contains the V definitions of the TubesUI user interface macros, the TubesFunc functional macro, the Tubes user macro and the example applications.
It is realised that the cross section of the tubes should be elliptical. However this would require further rotations to be carried out to orientate it correctly. The major use of the module is likely to be with Streamlines. As these tend to be 'smoothy' curved with short line segments it was decided that a circular cross section would be a sufficient approximation.
The low-level BlendyTubesMods library containing the module BlendyTubesCore does not specify a process. By default the express process will be used.

Abstract: The barn owl is a nocturnal hunter, capable of capturing prey using auditory information alone [1]. The neural basis for this localization behavior is the existence of auditory neurons with spatial receptive ﬁelds [2]. We provide a mathematical description of the operations performed on auditory input signals by the barn owl that facilitate the creation of a representation of auditory space. To develop our model, we ﬁrst formulate the sound localization problem solved by the barn owl as a statistical estimation problem. The implementation of the solution is constrained by the known neurobiology.

German police arrest Syrian suspected of planning attack
BERLIN: German police on Tuesday (Nov 19) arrested a 37-year old Syrian man suspected of exchanging bomb-building material through a messenger group with the aim of planning an attack, police and prosecutors said.
The Syrian stands accused of preparing "a serious act of violence against the state" and was arrested at his Berlin home, they added.
Police special forces searched the apartment of the suspect in Berlin who had started to buy chemicals and other materials needed to build an explosive device, the general prosecutors' office said.
"This (device) was meant to be detonated at an unknown time at an unknown location in Germany to kill as many people as possible," prosecutors said.
The accused notably purchased acetone and hydrogen peroxide in recent months, they added. Both are key components in the highly explosive TATP.
German police last Tuesday detained three people in the western city of Offenbach on suspicion of planning a bomb attack for the Islamic State militant group.

- name : string
- nmeaSource : url
- position : Position
- preferredPositioningMethods : enumeration
- sourceError : enumeration
- supportedPositioningMethods : enumeration
- updateInterval : int
- valid : bool
Signals
Methods
Detailed Description
The PositionSource type provides information about the user device's current position. The position is available as a Position type, which contains all the standard parameters typically available from GPS and other similar systems, including longitude, latitude, speed and accuracy details.
As different position sources are available on different platforms and devices, these are categorized by their basic type (Satellite, NonSatellite, and AllPositioningMethods). The available methods for the current platform can be enumerated in the supportedPositioningMethods property.
To indicate which methods are suitable for your application, set the preferredPositioningMethods property. If the preferred methods are not available, the default source of location data for the platform will be chosen instead. If no default source is available (because none are installed for the runtime platform, or because it is disabled), the valid property will be set to false.
The updateInterval property can then be used to indicate how often your application wishes to receive position updates. The start(), stop() and update() methods can be used to control the operation of the PositionSource, as well as the active property, which when set is equivalent to calling start() or stop().
When the PositionSource is active, position updates can be retrieved either by simply using the position property in a binding (as the value of another item's property), or by providing an implementation of the onPositionChanged
signal-handler.
Example Usage
The following example shows a simple PositionSource used to receive updates every second and print the longitude and latitude out to the console.
PositionSource { id: src updateInterval: 1000 active: true onPositionChanged: { var coord = src.position.coordinate; console.log("Coordinate:", coord.longitude, coord.latitude); } }
The GeoFlickr example application shows how to use a PositionSource in your application to retrieve local data for users from a REST web service.
See also QtPositioning::Position and QGeoPositionInfoSource.
Property Documentation
This property holds the unique internal name for the plugin currently providing position information.
Setting the property causes the PositionSource to use a particular positioning provider. If the PositionSource is active at the time that the name property is changed, it will become inactive. If the specified positioning provider cannot be loaded the position source will become invalid.
Changing the name property may cause the updateInterval, supportedPositioningMethods and preferredPositioningMethods properties to change as well.
nmeaSource : url |
This property holds the source for NMEA (National Marine Electronics Association) position-specification data (file). One purpose of this property is to be of development convenience.
Setting this property will override any other position source. Currently only files local to the .qml -file are supported. The NMEA source is created in simulation mode, meaning that the data and time information in the NMEA source data is used to provide positional updates at the rate at which the data was originally recorded.
If nmeaSource has been set for a PositionSource object, there is no way to revert back to non-file sources.
position : Position |
This property holds the last known positional data. It is a read-only property.
The Position type has different positional member variables, whose validity can be checked with appropriate validity functions (for example sometimes an update does not have speed or altitude data).
However, whenever a positionChanged
signal has been received, at least position::coordinate::latitude, position::coordinate::longitude, and position::timestamp can be assumed to be valid.
This property holds the preferred positioning methods of the current source.
- PositionSource.NoPositioningMethods - No positioning method is preferred.
- PositionSource.SatellitePositioningMethods - Satellite-based positioning methods such as GPS should be preferred.
- PositionSource.NonSatellitePositioningMethods - Non-satellite-based methods should be preferred.
- PositionSource.AllPositioningMethods - Any positioning methods are acceptable.
This property holds the error which last occurred with the PositionSource.
- PositionSource.AccessError - The connection setup to the remote positioning backend failed because the application lacked the required privileges.
- PositionSource.ClosedError - The positioning backend closed the connection, which happens for example in case the user is switching location services to off. As soon as the location service is re-enabled regular updates will resume.
- PositionSource.NoError - No error has occurred.
- PositionSource.UnknownSourceError - An unidentified error occurred.
- PositionSource.SocketError - An error occurred while connecting to an nmea source using a socket.
This property holds the supported positioning methods of the current source.
- PositionSource.NoPositioningMethods - No positioning methods supported (no source).
- PositionSource.SatellitePositioningMethods - Satellite-based positioning methods such as GPS are supported.
- PositionSource.NonSatellitePositioningMethods - Non-satellite-based methods are supported.
- PositionSource.AllPositioningMethods - Both satellite-based and non-satellite positioning methods are supported.
This property holds the desired interval between updates (milliseconds).
See also QGeoPositionInfoSource::updateInterval().
This property is true if the PositionSource object has acquired a valid backend plugin to provide data. If false, other methods on the PositionSource will have no effect.
Applications should check this property to determine whether positioning is available and enabled on the runtime platform, and react accordingly.
Signal Documentation
If update() was called, this signal is emitted if the current position could not be retrieved within a certain amount of time.
If start() was called, this signal is emitted if the position engine determines that it is not able to provide further regular updates.
This QML signal was introduced in Qt Positioning 5.5.
See also QGeoPositionInfoSource::updateTimeout().
Method Documentation
Requests updates from the location source. Uses updateInterval if set, default interval otherwise. If there is no source available, this method has no effect.
A convenience method to request single update from the location source. If there is no source available, this method has no effect.
If the position source is not active, it will be activated for as long as it takes to receive an update, or until the request times out. The request timeout period is source-specific.

Two thirds of parents miss the signs of depression in children
Parewnts have been warned not to ignore the symptpoms
by Neil ShawUp to two-thirds of parents struggle to spot signs of depression in their children, warns a new study.
Although the majority of mums and dads say they are confident that they would recognise if their child had depression, most admitted that there are “barriers” to spotting specific symptoms.
Forty per cent of parents struggle to differentiate between normal mood swings and depression, according to research conducted by the University of Michigan in the United States.
A further 30 per cent believe their children are good at hiding their feelings, with another third insisting that nothing would interfere with their ability to recognise signs of depression in their child.
Professor Sarah Clark, the study’s co-director, said: “In many families, the preteen and teen years bring dramatic changes both in youth behaviour and in the dynamic between parents and children.
“These transitions can make it particularly challenging to get a read on children’s emotional state and whether there is possible depression.
“Some parents may be overestimating their ability to recognise depression in the mood and behaviour of their own child.
“An overconfident parent may fail to pick up on the subtle signals that something is amiss.”
The poll also suggests that depression is a familiar topic for today’s schoolchildren.
One-in-four parents said their child knows a classmate or peer with depression, and one-in-ten added that their child knows someone who has committed suicide.
According to the Centres for Disease Control and Prevention, a US public health body, the suicide rate among those aged between 10 and 24 climbed by 56 per cent between 2007 and 2017.
Prof Clark added: “Our report reinforces that depression is not an abstract concept for today’s teens and preteens, or their parents.
“This level of familiarity with depression and suicide is consistent with recent statistics showing a dramatic increase in suicide among US youth over the past decade.
“Rising rates of suicide highlight the importance of recognising depression in youth.”
Parents should stay vigilant on spotting any signs of potential depression in their kids, she said, pointing to sadness, isolation, anger and irritability as key indicators.
Professor Clark added that parents could perhaps talk with their child about identifying a “go to” adult who can be a trusted confidant if they are feeling down.
The poll also found that most parents believe that schools should play a role in identifying potential depression, with seven-in-ten supporting depression screenings starting in secondary school.
Professor Clark added: “The good news is that parents view schools as a valuable partner in recognising youth depression.
“The bad news is that too few schools have adequate resources to screen students for depression, and to offer counselling to students who need it.”
The findings were based on responses from more than 800 American parents with at least one child in secondary school.
Signs of depression in children according to the NHS
Symptoms of depression in children often include:
- sadness, or a low mood that doesn't go away
- being irritable or grumpy all the time
- not being interested in things they used to enjoy
- feeling tired and exhausted a lot of the time
Your child may also:
- have trouble sleeping or sleep more than usual
- not be able to concentrate
- interact less with friends and family
- be indecisive
- not have much confidence
- eat less than usual or overeat
- have big changes in weight
- seem unable to relax or be more lethargic than usual
- talk about feeling guilty or worthless
- feel empty or unable to feel emotions (numb)
- have thoughts about suicide or self-harming
- actually self-harm, for example, cutting their skin or taking on overdose
Some children have problems with anxiety as well as depression. Some also have physical symptoms, such as headaches and stomach aches.
Problems at school can be a sign of depression in children and teenagers and so can problem behaviour, especially in boys.
Older children who are depressed may misuse drugs or alcohol.
Why is my child depressed?
Things that increase the risk of depression in children include:
- family difficulties
- bullying
- physical, emotional or sexual abuse
- a family history of depression or other mental health problems
Sometimes depression is triggered by one difficult event, such as parents separating, a bereavement or problems with school or other children.
Often it's caused by a mixture of things. For example, your child may have inherited a tendency to depression and also have experienced some difficult life events.
If you think your child is depressed
If you think your child may be depressed, it's important to talk to them. Try to find out what's troubling them and how they are feeling.
See some tips on talking to younger children and talking to teenagers.
Whatever is causing the problem, take it seriously. It may not seem a big deal to you, but it could be a major problem for your child.

Encourage them to talk to someone else they trust, such as another family member, a friend or someone at school.
It may be helpful for you to talk to other people who know your child, including their other parent.
You could also contact their school to see if they have any concerns.
When to get medical help
If you think your child is depressed, make an appointment with them to see your GP.
If necessary they can refer your child to their local child and adolescent mental health service (CAMHS) for specialist help.
See more about CAMHS .
If you are worried about any aspect of your child's mental health, you can call the charity YoungMinds' free parents' helpline on 0808 802 5544 for advice.
The YoungMinds website also has mental health support and advice for your child .

#assign n0_intro="active"> <#assign n1_firstentity="active"> <#assign mappedsuper="active">
We use @MappedSuperclass
for common properties across many entity beans.
It is common to have a mapped superclass with @Id
, @Version
and @WhenModified
properties like the example below and common for the mapped superclass to extend Model.
package org.example.domain; import io.ebean.Model; import io.ebean.annotation.WhenCreated; import io.ebean.annotation.WhenModified; import javax.persistence.Id; import javax.persistence.MappedSuperclass; import javax.persistence.Version; import java.time.Instant; /** * Base domain object with Id, version, whenCreated and whenModified. */ @MappedSuperclass public abstract class BaseDomain extends Model { @Id long id; @Version Long version; @WhenCreated Instant whenCreated; @WhenModified Instant whenModified; // getters and setters ... }

Our entity beans then extend this to inherit the common properties.
... @Entity public class Customer extends BaseDomain { String name; LocalDate registered; ...
package org.example.domain import javax.persistence.Entity @Entity class Customer : BaseDomain() { var name: String? = null }

Stitch
public struct Stitch
A Stitch is the result of the weaving action between a Warp and a Weft (See Warp.knit function) It describes the next thing that will be presented (a Presentable) and the next thing the Loom will listen to have the next navigation steps (a Weftable). If a navigation action does not have to lead to a Stitch, it is possible to have an empty Stitch

Chelsea buns filled with ground poppy seeds and citrus give these buns an Eastern European flavour.
For the bun dough, dissolve the yeast in 200ml/7fl oz of the lukewarm water.
Sieve the flour, sugar and salt into a large bowl. Rub in the butter.
Add the whisked eggs and the yeast mixture and enough additional water to make fairly soft dough.
Cover and leave to rest for 10 minutes.
Turn out onto a floured surface. Knead well, about 5-10 minutes, until the dough becomes firm and springy.
Put the dough into an oiled bowl, cover with cling film and leave to rise until it doubles in size – up to an hour.
Turn out onto surface and knead for 2-3 minutes. Leave to rest for five minutes.
For the poppy seed filling, grind the seeds in a coffee or nut grinder.
Heat the milk, sugar, orange zest, ground poppy seeds and raisins in a small saucepan over medium heat. Cook gently until the seeds absorb the milk, and the mixture thickens to spreadable consistency - about 15 minutes.
Add the lemon juice, brandy, orange liqueur and butter and cook for another two minutes.
Finally, add the vanilla and stir to combine. Remove from heat and turn out onto a medium-sized tray to speed up cooling. You can also be put in the fridge if necessary.
While the dough is proving, grease and sugar a 13 x 10in/33 x 25cm, deep sided tin.
Preheat oven to 200C/400F/Gas 6.
Roll out the dough to a 26 x 40cm/10½ x 16in rectangle. Brush the surface with melted butter and spread the poppy seed filling evenly over this, leaving a 2.5cm/1in border all the way round. Roll the long side of the dough forward into a fairly tight roll.
Moisten the farthest edge of the dough with water, and press the roll of dough onto it to form a seal.
Brush the log with melted butter.
Cut off about 2.5cm/1in at either end for neatness, and slice the log into 12 equal portions.
Place each bun cut-side down in the prepared tin, leaving a small gap between each one to allow for expansion.
Brush each bun with egg wash, cover with tea towel and set aside to prove for 30 minutes.
When the buns have proved, bake in the pre-heated oven, on the middle shelf, for 18-20 minutes.
Meanwhile, place the ingredients for the bun wash together in a pan and bring up to the boil. Boil for 3-4 minutes to create syrup. Keep hot.
Remove the Chelsea buns from the oven and brush immediately with the bun wash.
After five minutes, turn the buns out onto a cooling rack and separate each one. Allow the buns to cool a little then serve.

crypto(3)
NAMEcrypto - OpenSSL cryptographic library
SYNOPSIS
DESCRIPTIONThe OpenSSL crypto library implements a wide range of cryptographic algorithms used in various Internet standards. The services provided by this library are used by the OpenSSL implementations of SSL, TLS and S/MIME, and they have also been used to implement SSH, OpenPGP, and other cryptographic standards.
OVERVIEWlibcrypto consists of a number of sub-libraries that implement the individual algorithms. The functionality includes symmetric encryption, public key cryptography and key agreement, certificate handling, cryptographic hash functions and a cryptographic pseudo-random number generator.
NOTESSome of the newer functions follow a naming convention using the numbers 0 and 1. For example the functions: int X509_CRL_add0_revoked(X509_CRL *crl, X509_REVOKED *rev); int X509_add1_trust_object(X509 *x, ASN1_OBJECT *obj); The 0 version uses the supplied structure pointer directly in the parent and it will be freed up when the parent is freed. In the above example crl would be freed but rev would not. The 1 function uses a copy of the supplied structure pointer (or in some cases increases its link count) in the parent and so both (x and obj above) should be freed up.

Most of the time you can simply update from an earlier version to a newer one, by just overwriting the source files. If you encounter strange behaviors or errors, it might be a good idea to just delete the whole GameJolt API package and just reimport it again.
After updating you should test if everything works as expected. If not you should check the following:
Note: As with any asset package, any changes you made to the package will be lost on update, because the files will be overwritten.
While we try to be backwards compatible, it is sometimes inevitable to introduce breaking changes. Such incompatible changes may vary in their complexity, it might be just a renamed method or and additional parameter, but it might also be a renamed class or a larger change in the underlying architecture. Please always have a look at the changelog before you update to a new version.
This version has renamed the two most fundamental classes. Before this version there were two classes called Manager
. One inside the GameJolt.API
namespace and the other one in the GameJolt.UI
namespace. This lead to some confusion and therefore I decided to rename these files from Manager
to GameJoltAPI
and GameJoltUI
. The namespaces are still the same, so the fully qualified name looks a bit strange and redundant (GameJolt.API.GameJoltAPI
), but since most of the time you're just using the using
directive, this doesn't really matter.
This change has also the benefit that you can now use both classes from within the same file without having to use the fully qualified name.
Because of this change you're code will probably no longer work, because you are still referencing the Manager
classes, which no longer exist under that name. So your development environment will show several errors like this:
To fix these issues, you just have to change all occurrences of the old identifier with the new one. If you were always using the fully qualified name, you can just do a 'search&replace' within your development environment. For example you could just search for GameJolt.API.Manager
and replace it with GameJolt.API.GameJoltAPI
.
In this version I've refactored nearly all files. For most of the files it was just a matter of code formatting, but for some files I had to fix their naming scheme. Now the package is using a clean C# naming scheme (CamelCase). The provided prefabs are already adjusted accordingly, but if you have created new GameJolt UI prefabs or if you broke the prefab link to the original prefabs, you may have to adjust those settings in the inspector.
If you're just using the provided prefabs without changes, you probably don't have to do anything, but if you have changed those prefabs, you may have to check if everything works accordingly. If not, you should check out the inspector of all GamJolt UI scripts you have changed.

6.810 Engineering Interactive Technologies (fall 2021)
Lab 9: 3D Modelling the Lamp
In this lab, you will 3D model the lamp base and lamp shade and then 3D print both parts on a Prusa 3D printers. In the next labs, we will then make the lamp interactive by adding fabric to the lamp that includes touch buttons made from conductive yarn and LEDs to add color changing functionality to the lamp.
Steps:
- Install 3D Editor
- Watch 3D Modeling Getting Started Tutorials
- Short Cuts for 3D Modeling
- 3D Model the Lamp Base
- 3D Model the Lamp Shade
- Create Recess that Holds the Lamp Shade on the Base
- Export .stl File for Each 3D Model
Deliverables
At the end of the lab, upload to your student google drive:
- the 3D models saved in Blender (.blend file format)
- the exported 3D models from Blender (.stl file format)
Help us Improve Class Materials for Lab9:
Please let us know if you had any trouble with 3D modeling or if anything was confusing in the write up.
You can add your comments here.
Sign up for 3D Printing Slot: Since your 3D printed object will take around 6 hours to print, we ask you to sign up for a 3D printing slot here. You will be able to 3D print once you finished lab 8 3D modeling + lab 9 slicing, which we will do on friday.
(1) Install 3D Editor
For 3D modeling, we will use the 3D editor Blender
, which is open source
.
Blender is available for all major operating systems.
Install
the latest version of Blender from here: https://www.blender.org/download/. If you are already familier with a different 3D editor (e.g. Rhino3D, Fusion 360), you can also use it but if you get stuck, we will not be able to help you.
(2) Watch 3D Modeling Getting Started Tutorials
If you are not familiar with Blender, we recommend you watch these getting started tutorials
on youtube (number 1-15
, each is 3-12 minutes, ca. 75 minutes total): Blender Tutorials.
(3) Short Cuts for 3D Modeling
Here is a summary of the short cuts
which may come handy when you do your 3D modeling in the next steps:
Short cuts:
'a' = select all
'e' = extrude
's' = scale
'm' = merge
'7' = top view
'1' = side view
'g' + 'z' = grab and move in z
(4) 3D Model the Lamp Base
Our lamp consists of two parts:
the base of the lamp
(the cylindrical shape that will house the electronics), and the shade of the lamp
(the cone shape that will be covered with fabric).
We made video tutorials
that guide you through the modelling. The video quality might be better if you click on the youtube icon in the lower left corner, which opens a new tab and you can set the quality to 1080p
.
Creating the Lampbase Cylinder for Housing the Electronics (see video): Make a cylinder (vertices: 64, location: 0,0,0, radius: 5.0cm)
. Extrude to height 4.0cm
. Create another cylinder (vertices: 64, location: 0,0,0.3, radius: 4.8cm)
. Use a Boolean Modifier
on the first cylinder, and subtract the second cylinder from it by choosing Difference
.
(5) 3D Model the Lamp Shade
lamp shade will be placed on top of the lamp base. It has holes to let light shine through and it will be the place on which you can mount RGB LEDs. Please see the video below for detailed step-by-step instructions. The video quality
might be better if you click on the youtube icon in the lower left corner, which opens a new tab and you can set the quality to 1080p
.
Create Cylinder: Make a circle (vertices: 64, location: 0,0,0, radius: 4.6cm)
. Extrude and scale by 0.3cm
.
Create Lamp Shade Pillars: Select every second face
. Then extrude upwards (height: 8.3cm)
to create pillars from the faces. Scale faces inwards
to create angled pillars (inside radius: 1cm)
. Select inward facing edges, scale inwards.
Create Connector Ring for Pillars: To merge two pillars together, select two adjacent vertices
, merge them at the center. After all pillars are connected, extrude upwards (height: 2mm)
.
(6) Create Recess that Holds the Lamp Shade on the Base and add Hole for the USB cable
The way we modeled the base and the shade of the lamp, they do not really fit to each other and wouldn't connect tightly when just placed on top of each other. Therefore, we will add a recess to base
of the lamp that has enough space such that the lamp shade fits in it nicely.
Load both Models into one 3D Editor File: First, load both the 3D model
of the lamp shade and the lamp base into one Blender environment.
Align Lamp Shade over Lamp Base: Next, move the lamp shade down until the lower ring of the lamp shade overlaps with the lamp base
.
Subtract Lamp Shade from Lamp Base: Select the Lamp base, use a boolean modified to subtract the lamp shade from the lamp base, this creates a small recess.
In the final step, we also have to create a hole for our USB cable so we can connect the electronics inside our lamp to our computer.
Add Hole for USB Cable to Cylinder: Create a cylinder (vertices: 64, radius: 0.6cm)
and rotate it on the x-axis
to make it horizontal. Move cylinder to where the hole should be on the lamp base. Select the lamp base, use the boolean modifier 'subtract'
to subtract the cylinder from the lamp base, leaving the whole. Delete the cylinder.
(7) Export .stl File for Each 3D Model
slice the 3D model for 3D printing. For this, The 3D models have to be converted from Blender's internal file format (.blend) to another file format that the slicing software can load and process. The standard for saving digital models is the .stl file format
and we will use this file format to load models into the slicing software. The video below shows how you can save each of your 3D models as .stl files. The video quality might be better if you click on the youtube icon in the lower left corner. which opens a new tab and you can set the quality to 1080p
.
Export Lamp Base: Select only the lamp base, go to File -> Export -> Export .stl
, click checkbox 'selection only'
, use scale factor: 10
, click 'export'.
Export Lamp Shade: Select only the lamp shade, go to File -> Export -> Export .stl
, click checkbox 'selection only'
, use scale factor: 10
, click 'export'.
Deliverables
At the end of the lab, upload to your student google drive:
- the 3D models as saved in Blender (.blend file format)
- the exported 3D models from Blender (.stl file format)
Please let us know if you had any trouble with 3D modeling or if anything was confusing in the write up.

Codehaus XFire
DocumentationQuicklinksDevelopers
Sponsors |
XFire maintains two build systems side by side: Maven and Ant. Both can be used for testing and buliding jars. Maven is used for building releases and distributions. A couple notes on how our build system is set up: In the xfire directory, there are several different modules. These can be compiled individually or as an aggregate, named "xfire-all". The xfire-all module is solely used in the maven build to build an aggregate xfire-all jar. The ant build system does not require this. Building with AntBuilding individual jarsTo compile jars for all the modules run $ ant from the main directory. This will put a jar in each module's target directory. For example, the xfire-core jar will be placed in xfire-core/target as "xfire-core-VERSION.jar". Building an "xfire-all" jarTo compile an jar of all the xfire modules run $ ant all from the main directory. The resultant jar will be placed in xfire/target. Running TestsTo run tests for all modules run $ ant test from the main directory. To run tests for an individual module: $ cd xfire-core (replace core with any module you desire) $ ant test Building with MavenTo build with java 5.0 support you must included "-Dxfire.java5=true" in all your maven commands. Building all the individual jarsTo build jars for each xfire module and have them placed in your local maven repository, simply run "maven" from the main source directory. Building an individual moduleTo build an individual module: $ cd xfire-core (replace core with any module you desire) $ mvn install Building an "xfire-all" jar$ cd xfire-all $ mvn install or if you desire java 5.0 support: $ cd xfire-all
$ mvn -Dxfire.java5=true install
Additional notes - due to license problems you may need to install some jars manualy in your local repo. Like : - xfire-jibx module MUST be build with tests enabled ( if you turn test off with -Dmaven.test.skip then build will fail ). |

Social Media: Preparedness 101: Zombie Apocalypse
The following was originally posted on CDC Public Health Matters Blog May 16th, 2011 by Ali S. Khan.
There are all kinds of emergencies out there that we can prepare for. Take a zombie apocalypse for example. That’s right, I said z-o-m-b-i-e a-p-o-c-a-l-y-p-s-e. You may laugh now, but when it happens you’ll be happy you read this, and hey, maybe you’ll even learn a thing or two about how to prepare for a real emergency.
Good on the CDC for making an unpleasant topic palatable enough to read to the end.
Read the article, and create your disaster plan.. then consider this guide:

A comparison of distributed machine learning platform
A short summary and comparison of different platforms. Based on this blog and (Zhang et al., 2017).
We categorize the distributed ML platforms under 3 basic design approaches: 1. basic dataflow 2. parameter-server model 3. advanced dataflow.
We talk about each approach in brief: * using Apache Spark as an example of the basic dataflow approach * PMLS (Petuum) as an example of the parameter-server model * TensorFlow and MXNet as examples of the advanced dataflow model.
Spark
Spark enables in-memory caching of frequently used data and avoids the overhead of writing a lot of intermediate data to disk. For this Spark leverages on Resilient Distributed Datasets (RDD), read-only, partitioned collection of records distributed across a set of machines. RDDs are the collection of objects divided into logical partitions that are stored and processed as in-memory, with shuffle/overflow to disk.
In Spark, a computation is modeled as a directed acyclic graph (DAG), where each vertex denotes an RDD and each edge denotes an operation on RDD. On a DAG, an edge E from vertex A to vertex B implies that RDD B is a result of performing operation E on RDD A. There are two kinds of operations: transformations and actions. A transformation (e.g., map, filter, join) performs an operation on an RDD and produces a new RDD.
A typical Spark job performs a couple of transformations on a sequence of RDDs and then applies an action to the latest RDD in the lineage of the whole computation. A Spark application runs multiple jobs in sequence or in parallel.
A Spark cluster comprises of a master and multiple workers. A master is responsible for negotiating resource requests made by the Spark driver program corresponding to the submitted Spark application. Worker processes hold Spark executors (each of which is a JVM instance) that are responsible for executing Spark tasks. The driver contains two scheduler components, the DAG scheduler, and the task scheduler. The DAG scheduler is responsible for stage-oriented scheduling, and the task scheduler is responsible for submitting tasks produced by the DAG scheduler to the Spark executors.
The Spark user models the computation as a DAG which transforms & runs actions on RDDs. The DAG is compiled into stages. Unlike the MapReduce framework that consists of only two computational stages, map and reduce, a Spark job may consist of a DAG of multiple stages. The stages are run in topological order. A stage contains a set of independent tasks which perform computation on partitions of RDDs. These tasks can be executed either in parallel or as pipelined.
Spark defines two types of dependency relation that can capture data dependency among a set of RDDs: * Narrow dependency. Narrow dependency means each partition of the parent RDD is used by at most one partition of the child RDD. * Shuffle dependency (wide dependency). Wide dependency means multiple child partitions of RDD may depend on a single parent RDD partition.
Narrow dependencies are good for efficient execution, whereas wide dependencies introduce bottlenecks since they disrupt pipelining and require communication intensive shuffle operations.
Fault tolerance
Spark uses the DAG to track the lineage of operations on RDDs. For shuffle dependency, the intermediate records from one stage are materialized on the machines holding parent partitions. This intermediate data is used for simplifying failure recovery. If a task fails, the task will be retried as long as its stage’s parents are still accessible. If some stages that are required are no longer available, the missing partitions will be re-computed in parallel.
Spark is unable to tolerate a scheduler failure of the driver, but this can be addressed by replicating the metadata of the scheduler. The task scheduler monitors the state of running tasks and retries failed tasks. Sometimes, a slow straggler task may drag the progress of a Spark job.
Machine learning on Spark
Spark was designed for general data processing, and not specifically for machine learning. However, using the MLlib for Spark, it is possible to do ML on Spark. In the basic setup, Spark stores the model parameters in the driver node, and the workers communicate with the driver to update the parameters after each iteration. For large scale deployments, the model parameters may not fit into the driver and would be maintained as an RDD. This introduces a lot of overhead because a new RDD will need to be created in each iteration to hold the updated model parameters. Updating the model involves shuffling data across machines/disks, this limits the scalability of Spark. This is where the basic dataflow model (the DAG) in Spark falls short. Spark does not support iterations needed in ML well.
PMLS
PMLS was designed specifically for ML with a clean slate. It introduced the parameter-server (PS) abstraction for serving the iteration-intensive ML training process.
In PMLS, a worker process/thread is responsible for requesting up to date model parameters and carrying out computation over a partition of data, and a parameter-server thread is responsible for storing and updating model parameters and making response to the request from workers.
Figure below shows the architecture of PMLS.
- The parameter server is implemented as distributed tables. All model parameters are stored via these tables. A PMLS application can register more than one table. These tables are maintained by server threads. Each table consists of multiple rows. Each cell in a row is identified by a column ID and typically stores one parameter. The rows of the tables can be stored across multiple servers on different machines.
- Workers are responsible for performing computation defined by a user on partitioned dataset in each iteration and need to request up to date parameters for its computation. Each worker may contain multiple working threads. There is no communication across workers. Instead, workers only communicate with servers.
- '’worker’’ and ‘‘server’’ are not necessarily separated physically. In fact server threads co-locate with the worker processes/threads in PMLS.
Error tolerance of ML algorithm.
PMLS exploits the error-tolerant property of many machine learning algorithms to make a trade-off between efficiency and consistency.
In order to leverage such error-tolerant property, PMLS follows Staleness Synchronous Parallel (SSP) model. In SSP model, worker threads can proceed without waiting for slow threads. > Fast threads may carry out computation using stale model parameters. Performing computation on stale version of model parameter does cause errors, however these errors are bounded.
The communication protocol between workers and servers can guarantee that the model parameters that a working thread reads from its local cache is of bounded staleness.
Fault tolerance
Fault tolerance in PMLS is achieved by checkpointing the model parameters in the parameter server periodically. To resume from a failure, the whole system restarts from the last checkpoint.
Programing interface
PMLS is written in C++.
While PMLS has very little overhead, on the negative side, the users of PMLS need to know how to handle computation using relatively low-level APIs.

Tensorflow is the first generation distributed parameter-server system. In TensorFlow the computation is abstracted and represented by a directed graph. But unlike traditional dataflow systems, TensorFlow allows nodes to represent computations that own or update mutable state.
- Variable: a stateful operations, owns mutable buffer, and can be used to store model parameters that need to be updated at each iteration.
- Node: represents operations, and some operations are control flow operations.
- Tensors: values that flow along the directed edges in the TensorFlow graph, with arbitrary dimensionality matrices.
- An operation can take in one or more tensors and produce a result tensor.
- Edge: special edges called control dependencies can be added into TensorFlow’s dataflow graph with no data flowing along such edges.
In summary, TensorFlow is a dataflow system that offers mutable state and allows cyclic computation graph, and as such enables training a machine learning algorithm with parameter-server model.
Architecture
The Tensorflow runtime consists of three main components: client, master, worker.
- client: is responsible for holding a session where a user can define computational graph to run. When a client requests the evaluation of a Tensorflow graph via a session object, the request is sent to master service.
- master: schedules the job over one or more workers and coordinates the execution of the computational graph.
- worker: Each worker handles requests from the master and schedules the execution of the kernels (The implementation of an operation on a particular device is called a kernel) in the computational graph. The dataflow executor in a worker dispatches the kernels to local devices and runs the kernels in parallel when possible.
Characteristics
### Node Placement If multiple devices are involved in computation, a procedure called node placement is executed in a Tensorflow runtime. Tensorflow uses a cost model to estimate the cost of executing an operation on all available devices (such as CPUs and GPUs) and assigns an operation to a suitable device to execute, subject to implicit or explicit device constraints in the graph.
Sub-graph execution
TensorFlow supports sub-graph execution. A single round of executing a graph/sub-graph is called a step.
A training application contains two type of jobs: parameter server (ps) job and worker job. Like data parallelism in PMLS, TensorFlow’s data parallelism training involves multiple tasks in a worker job training the same model on different minibatches of data, updating shared parameters hosted in a one or more tasks in a ps job.
A typical replicated training structure: between-graph replication
There is a separate client for each worker task, typically in the same process as the worker task. Each client builds a similar graph containing the parameters (pinned to ps) and a single copy of the compute-intensive part of the computational graph that is pinned to the local task in the worker job.
For example, a compute-intensive part is to compute gradient during each iteration of stochastic gradient descent algorithm.
Users can also specify the consistency model in the betweengraph replicated training as either synchronous training or asynchronous training: * In asynchronous mode, each replica of the graph has an independent training loop that executes without coordination. * In synchronous mode, all of the replicas read the same values for the current parameters, compute gradients in parallel, and then apply them to a stateful accumulators which act as barriers for updating variables.
Fault tolerance
TensorFlow provides user-controllable checkpointing for fault tolerance via primitive operations: save writes tensors to checkpoint file, and restore reads tensors from a checkpointing file. TensorFlow allows customized fault tolerance mechanism through its primitive operations, which provides users the ability to make a balance between reliability and checkpointing overhead.
MXNET
Similar to TensorFlow, MXNet is a dataflow system that allows cyclic computation graphs with mutable states, and supports training with parameter server model. Similar to TensorFlow, MXNet provides good support for data-parallelism on multiple CPU/GPU, and also allows model-parallelism to be implemented. MXNet allows both synchronous and asynchronous training.
Characteristics
Figure below illustrates main components of MXNet. The runtime dependency engine analyzes the dependencies in computation processes and parallelizes the computations that are not dependent. On top of runtime dependency engine, MXNet has a middle layer for graph and memory optimization.
Fault tolerance
MXNet supports basic fault tolerance through checkpointing, and provides save and load model operations. The save operaton writes the model parameters to the checkpoint file and the load operation reads model parameters from the checkpoint file.

This library provides workarounds which allow the other Boost libraries to be used on otherwise non-conforming platforms. We hope that it will be possible to remove this library at some time in the future as standard library suppliers become more conforming.
The Python script: generate_cpp_c_headers.py creates a full set of C++ C header files (e.g. <cstdio>) that are missing on some platforms. The header files created by this script reside in the directory boost/compatibility/cpp_c_headers. To use the header files, add this directory to the include file search path. For example:
cxx -I/usr/local/boost/boost/compatibility/cpp_c_headers ...
Supported platforms are:
There are more powerful alternatives to using the Boost.Compatibility library CXX headers, e.g. STLport or ISOCXX. However, in contrast to these alternatives, the generate_cpp_c_headers.py script is very light-weight (less than 100 non-comment lines of Python code), much less ambitious, significantly easier to maintain and therefore more suitable as an interim workaround.

Several Boost libraries require the standard library's <limits> header, yet this header is not always supplied by non-conforming compilers and libraries. Header boost/limits.hpp simply includes the standard library <limits> header if available, otherwise includes boost/detail/limits.hpp. BOOST_NO_LIMITS from boost/config.hpp is used to determine <limits> availability.
Note also the test program limits_test.cpp
