[gecode-users] reified linear sum of booleans
Tias Guns
tias.guns at cs.kuleuven.be
Mon Jul 28 18:08:06 CEST 2008
Greetings,
I'm using a model in which I rely heavily on reified linear sums of
booleans. Unfortunately the existing boolean reified linear sum
implementatiom is horribly slow for this ! To overcome this, I'm currently
channeling all boolean variables to integers, and posting the reified
linear sum over the integers. This gives incredibly faster runtimes.
The first batch of constraints are regular reified linear sums, they are
constructed by reading a binary matrix and creating an IntArgs 'row' which
contains 0 or 1 (out or in). This 'row' is multiplied by an array of
decision variables, each representing one column. Doing so selects the
desired subset of those variables after which they are constrained and
reified to the variable representing that row:
for (int r = 0; r!=nr_r;r++ ) {
// make row
for (int c = 0; c!=nr_c;c++ ) {
row[c] = (1-tdb[r][c]); // complement
}
// sum(row*col_vars) = 0 <=> row_vars[r]
linear(this, row, col_vars, IRT_EQ, 0, row_varsBool[r]);
}
here, the col_vars is an IntVarArgs that is channeled to corresponding
BoolVars.
The second batch of constraints are imply-reified linear sums, having one
sided reification. Because one-sided reification is not implemented in
gecode directly, an extra auxiliary variable and constraint is used to
manage it:
for (int c = 0; c!=nr_c;c++ ) {
// make col
for (int r = 0; r!=nr_r;r++ ) {
col[r] = tdb[r][c];
}
// sum(col*row_vars) >= X <=> col_aux[c]
linear(this, col, row_vars, IRT_GQ, X, col_aux[c]);
// col_aux[c] => col_varsBool[c] (one-sided reificiation, reformulation
is) col_aux[c] =< col_varsBool[c]
rel(this, col_aux[c], IRT_LQ, col_varsBool[c]);
}
similarly as above, row_vars is an IntVarArgs channeled to corresponding
BoolVars.
This model works very well but still, I'm wondering if there would be a
better or cleaner way to model this, and if there are any plans to improve
the reified linear sum of boolean constraints.
Kind regards,
Tias

This is a very easy, configurable implementation of a Gashapon-style device.
Note: These instructions are for starting with the script. If you're using the "Easy Gacha - Ready to use" object, skip step #2.
Yes! It's modifiable, so just unlink the prims and delete the sign. If you have the skill and feel like doing it, you could even re-texture it.
Easy Gacha will give them change.
Easy Gacha will refund the whole amount given and remind them of the price.
Easy Gacha will refund the excess.
Easy Gacha will turn off until more items are available or you reconfigure it.
Easy Gacha will not allow anyone to play, but will give you the ability to export your configuration before restarting the script. I haven't actually been able to reach this point yet without configuring way too many items, but it should be robust enough to handle it.
Easy Gacha will still be able to be played if it was already configured, but will not be visible to the registry and will not be able to have its configuration changed. If the owner touches the object, it will try to get a new URL again.
Then they can administer your Easy Gacha, change its settings, change the price, etc. If you didn't mean to share, or want to remove that permission, just take your Easy Gacha back into your inventory and drop it in-world again. Each time it is rezzed it will create a new URL.
Because otherwise I cannot vouch for its safety. If I made the script modifiable, someone with ill intent could make it steal money, then give it away. It would still list me as the creator, but would be malicious.
The creator of the script should be listed as Zan Lightfoot
Also, if I made the objects modifiable and transferable, someone could put something malicious inside them and they'd still list me as the creator. Because the kit is free and the source code is open, there should be no problem with each person that wants one ordering a free copy from the marketplace.
If you want your notecards and your gacha-box to be transferable, simply create your own objects and notecards (copy the contents from mine) and set the permissions how you please. The script is transferable because it is no-mod.
You may contact me and I will probably help out, but I cannot guarantee a quick (or any) response. This was a labor of love. There is no official support, and Second Life comes... second. Please read the license.
If the script you have wasn't created by Zan Lightfoot, then I cannot vouch for its safety. Whoever created it may have altered it. You have been warned.
The script can give people a folder which is the name of the Easy Gacha object followed by the date.
For example, if you name the object "My Stuff", then someone might receive a folder that says:
My Stuff (Easy Gacha: 3 items 2013-10-06)
If the script is deleted or reset, any configurations not exported and saved to a notecard or elsewhere will be lost.
The script requires one available URL on the parcel/sim. See the LSL HTTP server for more details. Specifically, if it cannot obtain a URL, then it cannot be configured. As long as the ownership and inventory haven't changed, it can be stored and re-rezzed, but the URL is required for initial configuration. This can be resolved by finding the script(s) which are eating up more than their fair share of URLs and giving their creators a good slap in the face.
User/agent identification MUST be provided as UUID to be certain, because SL has yet to implement a way of looking up a UUID from a user-name or legacy-name reliably. W-Hat's agent lookup service has been implemented and seems to work reliably, but should always be verified because it's not official. To that end, W-Hat is used to find the agent key, then the agent key is used to get the username and display-name.
llMessageLinked( LINK_SET , 3000168 , (string)totalItems , buyerId );
If this feature is turned on, this script tells the entire object each time a purchase is made, indicating the total number of items, but not listing the individual items received. Excellent for most-recent board or custom, direct thank-yous.
llMessageLinked( LINK_SET , 3000169 , itemName , buyerId );
If this feature is turned on, this script tells the entire object which items were received. COULD OVERFLOW THE QUEUE ON MULTI-PLAY. Useful for playing a sound or particle effect when a specific item is bought, or custom reporting. Also useful if you want to keep a subscription list based on received items. Be mindful of your event queue.
llMessageLinked( LINK_SET , 3000170 , baseUrl , adminKey );
Only occurs if the owner creates and puts an inventory item with the name "EasyGachaAPI SignalOnNewURL" into the same prim as the script. This script will then tell the entire object the new URL that was allocated and the adminKey in use. Useful if you want to automatically signal your own external service to watch the script.
Use the LSL HTTP server to simplify configuration and control by putting advanced controls on the hosted pages of GitHub, then making browser-to-object calls. This prevents needing any parsing engine within the script, and greatly simplifies the "server-client" type interactions within the script. It means the only third party server needed is the host for the admin/stats interface. It also greatly reduces the memory impact of the script, freeing up space for further configuration.
Cross-Origin Resource Sharing has a number of security implications within browsers, and not all browsers handle it the same way. Thus the following rules have been adopted:
See this for some more detail on why.
See this for a list of supported features in LSL, which sadly doesn't include setting the CORS headers on responses.
To get around all this, we officially load the initial page via the script, and it loads all its libraries, CSS, and images via a single script tag. That way all AJAX calls are technically to the same domain of the original page.
GET secondlifeURL/[?dev=1]#<page>
Where the browser is sent
GET lslguru.github.io/easy-gacha/<version>/easy-gacha.min.js
Initial library load which takes care of bootstrapping and loading
everything else
POST secondLifeURL/[adminKey/]<verb>/<subject>
Body should always be JSON-encoded array, though it may be an empty
list. This overhead is acceptable for gaining simplicitly in parsing.
Setting a default rarity means we'd have to add to the items list every time a non-configured item was chosen. That would definitely run out of memory eventually, and would also add an unreasonable level of additional complexity. Instead, I'm going to make it as easy as possible to configure a batch of items at the same time. That way you could drop in 10,000 items (would take a while to load...) and configure them ~100 at a time. Memory testing will indicate where the limits to number of configured items is.
There would be so many of them scattered all over the screens that it would be ridiculous. Just move the mouse around... the hover-tips should provide sufficient help.
Yes, this could be done. I even came up with a reasonably fast way to scan the inventory. The configuration becomes a nightmare, and is definitely NOT easy for people...
Go ahead, try handing out 100 unsaved notecards (placeholders) in a folder. See what happens... I sure was surprised! Regular objects don't run into the problem until a higher number, but that's still unacceptable.

Asian markets down on trade uncertainty, unrest hits Hong Kong
HONG KONG: Asian markets turned lower on Monday (Nov 11) as another record close on Wall Street was overshadowed by uncertainty on the China-US trade talks, while Hong Kong was also hit by fresh protests in which at least one person was shot.
Expectations Beijing and Washington will agree a mini-pact have fuelled an equity rally for the past few weeks.
Hopes had been given an added boost Thursday after China said the two sides had agreed to roll back some tariffs as the negotiations progress.
But the US side sent out some confusing signals after that announcement, before US President Donald Trump denied such an agreement, leaving investors scratching their heads.
Still, White House trade adviser Peter Navarro provided a lift to sentiment, saying Trump could postpone tariffs on Chinese goods scheduled to take effect in December. The S&P 500 and Dow both ended at fresh all-time highs.
"President Trump's speech on Tuesday at the New York Economic Club offers the perfect soapbox for (him) to make a big political splash on both the US-China trade talks and section 232 auto investigation against the EU," said AxiTrader's Stephen Innes.
"The president has never been known to shy away from the spotlight, so keep eyes trained on this significant event."
Asian investors were unable to extend the winning streak.
Tokyo ended 0.3 per cent lower and Singapore shed 0.8 per cent with Seoul, Mumbai, Taipei, Jakarta and Manila also sharply lower. Sydney and Wellington edged up.
PROTESTER SHOT
Shanghai dropped 1.8 per cent, with traders keeping tabs on China's annual "Singles' Day" shopping frenzy - the world's biggest 24-hour shopping event - which acts as a gauge of the country's consumer spending.
Total gross merchandise volume settled through Alibaba's payments platform Alipay hit 192 billion yuan (US$27.4 billion) in the first 12 hours, the e-commerce titan said.
This put it on course to break last year's record of US$30.7 billion. The firm said the first US$1 billion was spent in just 68 seconds.
Hong Kong sank 2.6 per cent as the city was gripped by another wave of protests that have jammed up the transport network and led to the closure of several businesses.
At least one person was hurt after a police officer fired shots at demonstrators, as the unrest - which for five months has battered the city's image and dragged on the economy - shows no sign of letting up.
Tensions have soared in recent days following the death on Friday of a 22-year-old student who succumbed to injuries sustained from a fall in the vicinity of a police clearance operation a week earlier.
In early trade London and Frankfurt each fell 0.5 per cent, while Paris was off 0.3 per cent.
On currency markets the pound edged up but struggled to recover losses suffered Friday that came in reaction to news that Moody's had downgraded the outlook for Britain's debt, citing mounting policy challenges as the Brexit saga rumbles along.
- Key figures around 0820 GMT -

The Wildfire Management Tool is a visualization tool for wildland fire behavior students, instructors and tacticians. WMT merges the art of wildland firefighting and the science of fire behavior— it couples the language and logic of The Campbell Prediction System (CPS) with the fire spread equations developed by Richard Rothermel.
The purpose of the tool is to provide an analysis of a fireground's fire behavior potential and to visualize the areas of risk and/or opportunity.
Following is an overview of the WMT software. This version contains the following features:
Figure 1. Example demonstrating the alignment of forces concept.
Figure 1 shows an overview of the CPS software. On the left are a series of panels used for controlling and depicting the fire behavior inputs. In the center is a map and terrain viewer. On the right are the fire behavior outputs.
The Map Viewer is a 3D tool for selecting and viewing the location used for fire behavior calculations. Terrain can viewed from any perspective and on a variety of maps. The location of crosshairs at the center of the map viewer are used to obtain the terrain's slope and aspect, as well a the defining the latitude used to determine solar preheating of the fuel.
Figure 2. Map Viewer Crosshairs
The Map Viewer contains a set of crosshairs at the center of the viewer. The location of these crosshairs are used for the slope and aspect within the fie behavior calculations. Any change in location will be reflected immediately in the Map Location panel and the fire behavior panels.
One of the fundamental principles of the Campbell Prediction System method is that firefighters should recognize how the three primary forces of wind, slope and preheat control fire behavior. When these three forces are in "alignment", fire behavior is at its worst.
The CPS Dashboard allows these three forces to be displayed together so as to see their alignment.
Figure 5. Dashboard with controls arrayed to show Alignment of Forces.
Figure 5 shows the CPS Dashboard configured to show the direction and strength for each of three primary forces. Fire behavior is greatest when the directional arrows are all pointing in a similar direction.
Several control panels are used to establish the fire's environment. These controls are all dynamically coupled to the fire behavior outputs. Any change to the environment will be reflected immediately in the fire behavior displays.
Figure 6. Solar heating and date and time controls.
Solar preheating is controlled by date, time and location. This panel allows you to control the date and time. The location is controlled by the map viewer.
The direction of the solar rays is shown within the yellow compass rose.
Figure 7. Fuel tab showing the selected fuel model with a fuel loading
graph
The Fuel tab contains a control for selecting a fuel model. A graph of the fuel loading is shown for the selected model. Clicking the [?] icon will display a help guide with photos for the selected model.
Figure 8. Moisture tab showing a selected fuel moisture scenario
The Moisture tab allows you to select the initial fuel moistures used in the fire behavior calculations. Note that the 1hr dead fuel moisture will be adjusted by hourly air temperature, humidity and solar heating.
Figure 9. Air Temp tab showing air temperature cycle and
editable table.
The Air Temp tab allows you to establish the yesterday's actual temperatures and today's forecasted temperatures. The table is used to set the parameters for the hourly temperature curves displayed in the chart.
These values affect the dead 1 hour and cured herbaceous fuel moistures.
Figure 10. Humidity tab showing relative humidity cycle and
editable table.
The Humidity tab allows you to establish the yesterday's actual relative humidity and today's forecasted relative humidity. The table is editable and it is used to set the parameters for the hourly temperature curves displayed in the chart.
These values affect the dead 1 hour and cured herbaceous fuel moistures.
Figure 11. Wind tab showing general wind speed and
direction with slider controls
The Wind tab lets you control the general winds used throughout the fire behavior calculations. The sliders allow you to control the wind speed and the wind direction.
When experimenting with the effects of wind, you may note that the wind speed also has a cooling effect on the fuel.
Figure 12. Map Crosshairs panel showing current location and
terrain.
The Map Location panel shows the location of the map viewer's crosshairs. This location affects the terrain and aspect, the sunrise and sunset times, and solar preheating.
 All of the fire behavior panels are dynamic. That is, any change in time, location, wind, fuel model, moisture, air temperature or humidity will be reflected immediately in the following panels.
Figure 13. Fire Spread
This dynamic panel shows the direction of maximum spread and the flame length. Wind is often a dominating force, but note that when the wind speed is low that the terrain aspect and slope become a greater influence.
Experiment with various wind directions and speeds on different terrain aspects and slopes to better understand this relationship.
Figure 14. Fuel Temperatures
This dynamic panel shows the computed fuel temperature and air temperature at the current location. This chart reflects the solar preheating of fuel and responds to changes in location.
A precept of the Campbell Prediction System method is that firefighters should recognize when fuel is, or will be, at its peak temperature. Experiment with changes in the terrain aspect to see when the hours of peak fuel temperature occur.
Figure 15. Haul Chart
The Hauling Chart is recognizable fire behavior diagram in wildland firefighting. The Haul Chart was so named because it infers the relative intensity of the fire behavior through graphical representations of firefighters working—haul firefighters, equipment working—haul equipment, trees torching—haul retardant, and crown fire—haul everybody to safety. Since fireline intensity and flame length are directly proportional (Byram, 1959)—the larger one gets the larger the other gets—and since we can visually assess the flame length the Haul Chart is an excellent tool for measuring the safety and effectiveness of various fireline resources.
The fireline interpretations of the Haul Chart are as follows: Figure 15. Haul Chart Interpretations (from Fireline Handbook, Appendix B.)
| FLAME LENGTH (Feet) | FIRELINE INTENSITY (BTU/Ft/Sec | INTERPRETATIONS |
|---|---|---|
| 0-4 | 0-100 | Persons using handtools can generally attack fires at the head or flanks. Handline should hold the fire. |
| 4-8 | 100-500 | Fires are too intense for direct attack on the head by persons using handtools. Handline can not be relied on to hold fire. Equipment such as dozers, engines, and retardant aircraft can be effective. |
| 8-11 | 500-1,000 | Fires may present serious control problems such as torching, crowning, and spotting. Control efforts at the head of the fire will probably be ineffective. |
| 11+ | 1000+ | Crowning, spotting, and major runs are common, control efforts at the head of the fire are ineffective. |
| ADJECTIVE RATING | FLAME LENGTH | IMPLICATION |
|---|---|---|
| LOW | 0-1 | Fire will burn and will spread however it presents very little resistance to control and direct attack with firefighters is possible |
| MODERATE | 1-3 | Fire spreads rapidly presenting moderate resistance to control but can be countered with direct attack by firefighters |
| ACTIVE | 3-7 | Fire spreads very rapidly presenting substantial resistance to control. Direct attack with firefighters must be supplemented with equipment and/or air support. |
| VERY ACTIVE | 7-15 | Fire spreads very rapidly presenting extreme resistance to control. Indirect attack may be effective. Safety of firefighters in the area becomes a concern. |
| EXTREME | >15 | Fire spreads very rapidly presenting extreme resistance to control. Any form of attack will probably not be effective. Safety of firefighters in the area is of critical concern. |
Selecting the appropriate fuel model is an important aspect for computing fire behavior. Portions of the GTR-INT-122 - Aids to Determining Fuel Models For Estimating Fire Behavior and RMRS GTR-153 - Standard Fire Behavior Fuel Models have been included to assist in this task.

The guides for fuel models can be browed in the help system. Also, help for a specific fuel model can be obtained from the help button on the Fuel tab.
The CPS software supports an auto-update feature. This feature ensures you have the latest software modules and plugins installed. The updates are delivered via the Web.

CQL Time values are used to represent a time of day, independent of the date. Time value must be known to at least the hour precision, and potentially to the millisecond precision. Time values are specified using at-symbol (@) followed by an ISO-8601 textual representation of the Time value:
@T12:00:00.0Z
@T14:30:14.559-07:00
Note that the Time value literal format is identical to the time value portion of the DateTime literal format.
For Time values, timezone may be specified as either UTC time (Z), or as a timezone offset. If no timezone is specified, the timezone of the evaluation request timestamp is used.
Specifically, because Time values may be specified to varying levels of precisions, operations such as comparison and duration calculation may result in null, rather than the true or false that would result from the same operation involving fully specified values.

Had a marvellous time at PyCon UK 2007, a conference about the Python programming language. In the event everyone from Resolver bar one of our directors went along. We met loads of great and interesting folks, heard many excellent talks, and gave a few of our own: Michael talked about driving Microsoft's natty new Silverlight technology using IronPython. Giles talked about his concept of the New Age of the Amateur: End-user Computing without Tears, and I gave a little talk about test-driven development for beginners, which can be downloaded here:
My few photos are also online.
As reported on Groklaw - Complaint Filed by CCIA with FTC Re Fair Use, a conglomerate of computer, technology and communication companies are filing suit against major copyright holders such as movie studios, sports leagues and publishers, to prevent them from continuing the practice of misleading the public with their threatening copyright notices. The nitty-gritty of the filing is that notices such as
"WARNING: For private use only. Federal law provides severe civil and criminal penalties for the unauthorized reproduction, distribution or exhibition of copyrighted motion pictures and video formats."
at the start of movies serves to intimidate the public from attempting the many operations to which they are legally entitled, and even encouraged, by US Federal laws and equivalents globally.
Time to get on the bandwagon? Anyone else interested in conspicuously taking photos of the copyright notice on the opening day of some blockbuster movie, and when they come to eject us from the cinema, find that we're handcuffed to our front row seats?
So I'm helping a friend create a small website. Casting around for lightweight tools, I remember that an intelligent and influential blogger, much admired by me, has founded a software company which produces, amongst other things, City Desk, a web site creation tool.
Checking out their website, I am delighted to find there is a free-to-use version for small projects much like the one I am embarking on. I download it, install it, and fire it up eagerly. Just about the last thing I expected to see was this.

Just goes to show, creating software which just works is a tough problem. If the likes of Joel can't figure it out, what hope do the rest of us have...?
Update: It looks like the problems are due to my Windows user account being limited privs. I perform installs and the like with elevated privs, using the brilliant MakeMeAdmin.cmd. It looks like running CityDesk for the first time performs some install-related activities, such as setting up the Platform SDK, which require admin privs. Once this is done, subsequent runs can be done as a limited privs user with no problems.
Rufus comments on certain English educational establishments becoming hotbeds of Northern cultural celebration. I can't argue with the unintentional comedy of the idea, but at the same time, such moves seem to my mind to be causes for both celebration - long overdue acknowledgements of the richness of human experience that shaped countless generations across vast tracts of this land, and simultaneously a regrettable sign of protectionism, incited by the relentless erosion of the very culture they intend to promote.
The London Cockney may also be a thing of the past, but at least they have been preserved in the minds of the current generation, albeit as some kind of morbid parody. In contrast, the richness and warmth of traditional Northern lifestyles is right on the verge of slipping away silently, if it hasn't already entirely done so. A culture as different from the South as another country, in everything from their food to their industry. It may be a culture that is now almost entirely lost to the inexorable market forces of a wealthier and more powerful neighbour, but it is a culture that valued human traits which are sorely missed in this harsh world.
With dialects that as recently as my grandparents' generation were completely incomprehensible to the rest of the country, dialects that are as close to ancient tongues as any alive today. A rich and vital part of this country's history, political struggles, battles fought and lost, the veritable heartland of the industrial revolution that gave birth to the modern age - all lost, unappreciated, and almost unremarked, save for the odd enigmatic reference to whippets and flat caps.
Hey. I'm doing some Perl coding on the side. Who knows a good way to interleave two lists? For example, combining (1, 3 ,5) and (2, 4, 6) to produce ((1, 2), (3, 4), (5, 6)) ?
It's easy, Perl has a built-in zip operator:
`my @result = (1, 3 ,5) ¥ (2, 4, 6)`
Brilliant, thanks. Hang on. What the crap!? Is that really a Yen symbol in there?  Yeah, I know, its a little weird, but since Perl supports source code unicode encodings, we thought "why not?"  Geddit?
Right. I see that now. Um. So which unicode Yen symbol do I use?
¥ U+00A5 YEN SIGN ￥ U+FFE5 FULLWIDTH YEN SIGN
They both look the same in my browser. In fact, they both just look like question-marks in many people's browsers.
Oh, you can easily tell the difference - one of them simply won't work. Just try them both out until you find the one that works!!!! :-)
Right. Brilliant. And who is responsible for this gem?
Oh, that was Larry. Look, if you don't like it, come to think of it, it's been renamed recently. The zip operator is now simply spelt 'Z'.
Yeah, whoever would have predicted that might happen? Guess who gets their language designer privileges revoked? Morons.  Directed by Ian Rickson. At the National Theatre's Lyttelton theatre.
As I was forewarned is typical of Pinter, difficult to untangle a point, but nevertheless both chilling and amusing in turns. Having said that, I'd really have to go and read all about it before I could decide whether I actually liked it or not, which I guess means that currently I don't. 4/10
"It's gonna be OK."
That's the new "reimagined" version, Dad. I don't really do much television, and for 2006, downloads of Battlestar was pretty much the only exception. It's edgy and well-written, and it leaves me breathlessly excited, and yes it had that lull on New Caprica about five episodes in, but then it blossomed again, experimenting with one-off shows, cool ideas, and great characters that remain emotive and involving while staying well clear of Dawson's Creek. And what a series finale! Blowing the whole stack of Cylon sleeper agents all at once, the awful yawning realisation as they each heard the activation signal in the back of their minds, all drawn to converge on the same room, what a headfuck, with the psychedelic nebula backdrops all around, to the rising strains of All Along the Watchtower, as Apollo discovers Starbuck is still alive. Hooray! Loved it loved it loved it. 8/10.

Aw, heck, I dunno. It's kinda down to Earth and charming, but also plain and slow-moving. And sure, that was deliberate, it wanted to tell a simple, powerful story in the terms of its protagonists, within the context of rural life. But I couldn't really get into it, despite really wanting to. Some of the acting was a bit lacking. IMDB informs me that it's a true story. Fair enough. It's still 4/10.

Meet Katie. Katie is starting a new job for the third time in the last five years. Her employer has set her up with a 401(k) plan, but Katie doesn’t want to start saving from scratch. She’s determined to find her old passwords and take action.
Katie has three options. A lot of her friends have cashed out their accounts, but lost half of their nest egg to penalties and taxes. Katie could also do nothing, but she's worried about juggling multiple investments and rising fees eroding her old balances.
Katie decides consolidating into a single account is the best decision.
Starting the process comes with a host of questions: What are the tax implications of a transfer? Can a 403(b) transfer into an 401(k)? What's a Roth account? Should she manage her own money or hire an advisor?
She tries to find the answers on her own, but it's difficult for her to know if she’s on the right track.
When she finally initiates her transfer, Katie feels like her life has been taken over by phone calls, mailing forms, and faxing information between her providers.
Despite her effort, it’s been months and her accounts haven’t been consolidated. There seems to be no end in sight.
Over 16 million people with employer accounts switch jobs every year, just like Katie. But 89% of transfers are never completed.
Manifest is transforming the opaque transfer process into a delightful experience. With our help, Katie should be able to locate her savings, get the guidance to make decisions, and know where her money is every step of the way.
Switching jobs provides an opportunity for employers to reinforce their connection with participants. With Manifest, Katie’s employer empowers her with access to one-click consolidation.
She can now start her new job, and her new consolidated retirement account, with confidence.
We are a team of technologists who believe technology should feel effortless, expand accessibility, and create time for human connection. Manifest is changing the retirement story for millions. Join us as we maximize retirement outcomes for all.

Details of a change to the funding agreement used by schools converting to academy status.
The Department for Education has today made some minor changes to the model funding agreement to be used by schools in their conversion to academy status.
From today, head teachers in mainstream and alternative provision academies will be given greater freedom over the teachers they employ - giving them the same advantages as independent schools, free schools, studio schools and university technical colleges.
A Department for Education spokesman said:
Independent schools and free schools can already hire brilliant people who have not got qualified teacher status (QTS). We are extending this flexibility to all academies so more schools can hire great linguists, computer scientists, engineers and other specialists who have not worked in state schools before. We expect the vast majority of teachers will continue to have QTS. This additional flexibility will help schools improve faster. No existing teacher contract is affected by this minor change.
The funding agreements for all new academies - which are essentially contracts between the Secretary of State and the organisation which establishes and runs the school (‘the academy trust’) - will now state that academies can employ teaching staff who they believe to be suitably qualified - without the automatic requirement for them to have qualified teacher status.
Existing academies can request for their funding agreements to be changed to include this new freedom if they wish.
No existing contracts for any teacher in any academy will be affected by this change.
This policy will free up academies to employ professionals - like scientists, engineers, musicians, university professors, and experienced teachers and heads from overseas and the independent sector - who may be extremely well-qualified and are excellent teachers, but do not have QTS status.
As with the independent sector and free schools, the vast majority of teachers employed will continue to have QTS, as it will remain the highly-respected professional status for teachers - and one that all teachers training in the state sector must continue to meet.
This new freedom for academies will allow them to bring in professionals who will offer a wealth of knowledge and new skills for our state schools.
Ensuring the highest quality of teaching is paramount to the success of each school. Head teachers know this, which is why we trust them to employ staff that they believe to be well-qualified for the job.
All schools will continue to be held accountable for the quality of teaching through Ofsted inspection and the publication of school performance data.
As with free schools, because of their unique and specialist role, SEN Coordinators and designated teachers for looked-after children will still be required to have QTS. All teachers in special academies will also still need this qualification.
The successful independent school sector already takes the opportunity to employ teaching staff who do not hold QTS, as do a number of the first 24 free schools:
Brighton college has risen from 147th among independent schools to 18th and is the only school in England to have improved its ranking every single year for 6 years. It was awarded the Sunday Times Independent School of the year.
Richard Cairns, Head master of Brighton College, said:
I strongly believe that teachers are born not made and I will actively seek out teachers from all walks of life who have the potential to inspire children.
At Brighton College, this year’s Sunday Times Independent School of the Year, we have 39 teachers without formal teaching qualifications, including me!
Some have come straight from university: our History and politics department has three recent graduates, all with Firsts from Oxford or Cambridge and all excellent teachers. Others have come from other careers: an investment analyst, a lawyer, a management consultant, a nuclear physicist and someone from the BBC.
Once teachers are in the school, they have a reduced teaching timetable to allow them to spend time observing other good teachers and are actively mentored. By the end of the year, they are, in our view, better trained than any PGCE student.
Katy Ricks, Head teacher of top independent school Sevenoaks, said:
The key aim for heads in recruiting staff is quite simply to find the best possible person to do the job. While of course qualifications and experience will play a part in the selection process, in the end, I am seeking ability, enthusiasm and potential.
As an untrained teacher myself, my own experience and those of my colleagues around me demonstrates clearly that good classroom practice, of course essential to being an outstanding teacher, can be learned on the job as long as there is a supportive framework within the school.
The Barnfield Federation is a highly successful education group made up of Barnfield College, Barnfield South and West Academies, the country’s first studio school and Barnfield Moorlands Free School. The studio school and free school have numerous staff without QTS including drama, English and Maths teachers all with degrees.
Sir Peter Birkett, Chief Executive of the Barnfield Federation, said:
The removal of QTS has proven very helpful to us, we are now attracting a broader range and an increased number of applications from people who would have otherwise been denied the opportunity to teach. The removal of barriers that allow us to employ the right people is absolutely critical to our success and therefore welcomed.
Langley Free School appointed a professional actor as a drama teacher, and a professional singer for music. In an interview with The Independent, the head teacher, Jane Sculpher, speaking during the school holidays, said:
Our drama teacher is off playing Cinderella in pantomime. The singing teacher will be away singing in Rome. They’re working at what they do. They’re not qualified teachers but they’ve been taught to degree level and are very, very able teachers.
Batley Grammar School’s head of Geography is an Oxbridge graduate and taught at independent schools before joining Batley.
West London Free School has appointed the former Head of Classics at a renowned independent school, as their classics teacher. They have also appointed an artist with several degrees as an art teacher, as they felt her skills and experience would be a huge benefit to the pupils at the school.

“We have visited the pretty English burial-ground, and the tomb of Smollet, which in the true English style is cut and scratched all over with the names of fools, who think thus to link their own insignificance to his immortality. We have also seen whatever else is to be seen, and what all travellers describe: to-morrow we leave Leghorn—for myself without regret: it is a place with which I have no sympathies, and the hot, languid, damp atmosphere, which depresses the spirits and relaxes the nerves, has made me suffer ever since we arrived.” — Anna Brownell Jameson, The Diary Of An Ennuyee

Sun Princess has again grappled with an outbreak of norovirus aboard one of their vessels that left Perth for Singapore earlier this month.
The highly contagious virus, which causes vomiting and diarrhoea, reportedly spread across the Carnival Australia owned-ship causing crews to evacuate all passengers for fumigation in Singapore yesterday.
The ship departed Fremantle on November 1, on what was supposed to be a 12-night voyage.
While the ship has recommenced its journey, it’s understood some passengers have decided to fly back to Australia.
Norovirus symptoms general start in the first or second day of contamination and usually lasts between one and three days.
The virus can be spread through touching objects, survive on surfaces and is easily spread from person-to-person.
In 2016 and 2017, the Carnival Australia experienced a string of outbreaks on eight consecutive voyages.
The outbreaks lead to a large scale Class Action Investigation into Carnival Australia on behalf of the affected passengers.
A Princess Cruises spokeswoman creating and maintaining a healthy onboard environment was “always a priority”.
“Onboard sanitation was swiftly stepped up following some guests reporting gastrointestinal symptoms confirmed as being due to Norovirus,” she said.
“The vast majority of the 2000 guests on Sun Princess were unaffected but it takes relatively few cases of illness to be reported for onboard sanitation measures to be increased.
“Out of an abundance of care and in line with best practice, extra cleaning of the terminal was also carried out yesterday.
“Guests remain isolated while they have symptoms.
“There are also constant reminders for guests to wash their hands regularly to stay well and help maintain a healthy environment.”
She wouldn’t comment when asked if passengers would be compensated or reveal how many people had been affected.


Compiles a piece of HTML string or DOM into a template and produces a template function, which
can then be used to link scope
and the template together.
The compilation is a process of walking the DOM tree and trying to match DOM elements to
directives
. For each match it
executes corresponding template function and collects the
instance functions into a single template function which is then returned.
The template function can then be used once to produce the view or as it is the case with
repeater
many-times, in which
case each call results in a view that is a DOM clone of the original template.

 <input ng-model="name">
 <textarea ng-model="html"></textarea>

it('should auto compile', function() { expect(element('div[compile]').text()).toBe('Hello Angular'); input('html').enter('{{name}}!'); expect(element('div[compile]').text()).toBe('Angular!'); });
$compile(element, transclude, maxPriority);
element – {string|DOMElement} –
Element or HTML string to compile into a template function.
transclude – {function(angular.Scope[, cloneAttachFn]} –
function available to directives.
maxPriority – {number} –
only apply directives lower then given priority (Only effects the root element(s), not their children)
{function(scope[, cloneAttachFn])}
– a link function which is used to bind template (a DOM element/tree) to a scope. Where:
scope
- A Scope
to bind to.cloneAttachFn
- If cloneAttachFn
is provided, then the link function will clone the
template
and call the cloneAttachFn
function allowing the caller to attach the
cloned elements to the DOM document at the appropriate place. The cloneAttachFn
is
called as:
cloneAttachFn(clonedElement, scope)
where:
clonedElement
- is a clone of the original element
passed into the compiler.scope
- is the current scope with which the linking function is working with.Calling the linking function returns the element of the template. It is either the original element
passed in, or the clone of the element if the cloneAttachFn
is provided.
After linking the view is not updated until after a call to $digest which typically is done by Angular automatically.
If you need access to the bound view, there are two ways to do it:
var element = $compile('
{{total}}
')(scope);
var templateHTML = angular.element('
{{total}}
'), scope = ....; var clonedElement = $compile(templateHTML)(scope, function(clonedElement, scope) { //attach the clone to DOM document at the right place }); //now we have reference to the cloned DOM via `clone`
For information on how the compiler works, see the Angular HTML Compiler section of the Developer Guide.


Hi All.
I have been chasing dow a tricky bug and think i have finally reached the solution, however after looking through the emoncms.log file this morning after the backup script ran, I see that the times are not 1 hour behind.
I am using a home Linux PC to log all of the data on and the I have got my backup script appending a line into the emoncms.log file when it does things so that I can investigate.
I am guessing that the cause of this is now we have entered BST, so the php script will need updating, but where do I begin?
Jimmy
Re: emoncms.log Time incorrect
Hello Jimmy, you should not need to edit any scripts to deal with BST. Could it be time settings related on your computer?
Re: emoncms.log Time incorrect
Hi,
I thought that as well, However please see the attached homeserv.txt
I have broken the document into logical sections.
First is me running the timezone configurer and its output (Europe / London)
Then the emoncms.log
Before writing anything to it with the new timezone.
Note the 06:18:44.005 Disconnect, then the INFO after that at 7:18
Then the restart of the MQTT_INput script again at 6:18
The next section is me just writing to the emoncms with the php page, so I restarted the MQTT_INPUT service
This still prints the time in UTC
The dbBackup appends the emoncms.log directly from bash, (echo "Some Text" | tee -a /var/log/emoncms.log /var/log/dbBackup.log)
Its not the end of the world, today was the first day that the backup script worked as it should, so I'm very happy about that as I have 5GB of feed data and the mysqldump method is a nightmare on everything, 30+ min downtime to backup on a morning. Using percona Xtrabackup I have <30 seconds of missed feeds, If I move that to 2-3AM It wont be anything to worry about at all.
Oh and incase it matters the system details are
Re: emoncms.log Time incorrect
Interestingly though, creating a php page with the following code
and running it with
returns the correct time: 15:03:16
Hmmm... What generates the date timmestamp for emoncms.log?
Jimmy
Re: emoncms.log Time incorrect
Ok I found it, its in Lib/EmonLogger.php Line 69
Its hard written into the logging script,
I'll adapt my backup script to match...
Jimmy

Few materials can be made to magnetically levitate stably above the magnetic field from a permanent magnet. Although you can obviously and easily achieve magnetic repulsion between any two magnets, the shape of the field causes the upper magnet to push off sideways, rather than remaining supported, rendering stable levitation “impossible” for magnetic objects (see Earnshaw's Theorem). Strongly diamagnetic materials, however, can levitate above powerful magnets.
With the availability of rare earth permanent magnets in recent years, the strong diamagnetism of pyrolytic carbon makes it a suitable demonstration material for this effect.
The kit includes all the materials needed to perform the levitation:
(1) Two pieces of pyrolytic graphite - measuring 10 mm x 10 mm x 0.75 mm (one needed plus an extra)
(2) Four neodymium “N52” super strong permanent magnets – measuring 1 cm3 (pull force 3 kg each)
(3) One straight-forward set of instructions to perform the levitation
Note: “N52” is the strongest grade of neodymium magnet but are also very fragile. The magnets are triple-plated in nickel-copper-nickel to protect them, but please note you must handle them with care.
The instructions are not very complicated. In brief, the key is to arrange the magnets firmly together in a square (alternating North/South works well), and then simply float the piece of pyrolytic graphite on top!
With this Mini-Lab, we aim to change that. Stop missing out. Build your own Arch!
We supply everything you need: correctly shaped “voussoirs” (wedge-shaped elements used in building an arch); “abutments” that support each side of the arch; and a ‘centring’ (the temporary structure upon which you lay the stones of the arch during construction). It's remarkably easy to do with the materials in this Mini-Lab.
Included with your Mini-Lab are the following:
(1) Nine stones (aka "voussoirs") (plus we added two extra for a total of 11)*;
(2) A simple assembled wooden frame that provides abutments on both sides.
(3) A centring (in the form of two quarter-circles).
(4) An S.T.E.M. Store of Canada information sheet that provides step-by-step instructions and additional background information.
Notes:
(1) The stones included with this Mini-Lab are all identical. Any one of these stones may function as the famous “Keystone” (being the final piece placed during construction that locks all the stones into position, allowing the arch to bear weight)!
(2) The Loonie coin (not included with the Mini-Lab) is displayed in some of the pictures to give you a sense of the size of the Arch.
(3) We tried placing a 15-pound weight on top the arch - it held it up no problem (you can see there was no cheating involved)! Can you do the same? Maybe you can achieve even more weight?
Included are:
(1) One 3-in-1 key chain that includes a 5Mw laser (details below)
(2) 12" of black electrical tape
(3) 6" of 32 gauge wire
(4) Straight-forward step-by-step illustrated instructions (for an adult) so that you can easily and successfully perform the double-slit experiment at home in less than 10 minutes
(5) A kid-friendly explanation of the experiment
The included 3-in-1 key chain is better than you normally find in Canada - it has a red laser pointer, a UV torch, and an LED white light! You can choose the colour of laser that will come with your kit: there are 6 colours - green, black, purple, red, blue and silver. All pointers are 5Mw and have a nice high power, strong, long lasting beam! Besides the double-slit experiment, it's also great for presentations, cats, pets and emergencies!
For an excellent overview of how and why a prism bends and separates white light into a rainbow of colours, click here (2:34 minutes).
Our Mini-Lab gives you confidence that you are using the prism correctly. All our prisms are made of acrylic which is 200% more transparent, weighs less and is more durable than glass. The Right Angle Prism is precision crafted and makes an excellent student prism.

Publishing a Package
In the previous sections, we dove into the details of how our MapToSurface package is set up with custom nodes and example files. But how do we publish a package that has been developed locally? This case study demonstrates how to publish a package from a set of files in a local folder. There are many ways to publish a package. Below is the process that we advise: publish locally, develop locally, and then publish online. We'll start with a folder containing all of the files in the package.
Uninstalling a Package
Before we jump into publishing the MapToSurface package, if you installed the package from the previous lesson, uninstall it so that you're not working with identical packages.
Begin by going to Packages>Manage Packages...
Select the button corresponding to "MapToSurface" and select "Uninstall...". Then restart Dynamo. When reopening, when you check the "Manage Packages" window, the MapToSurface should no longer be there. Now we're ready to start from the beginning!
Publishing a Package Locally
Note: As of writing this, Dynamo package publication is only enabled in Dynamo Studio or Dynamo for Revit. Dynamo Sandbox does not have publishing functionality.
Download and unzip the example files that accompany this package case study (Right click and "Save Link As..."). A full list of example files can be found in the Appendix. MapToSurface.zip
This is the first submission for our package, and we've placed all of the example files and custom nodes into one folder. With this folder prepared, we're ready to upload to the Dynamo Package Manager.
- This folder contains five custom nodes (.dyf).
- This folder also contains five example files (.dyn) and one imported vector file (.svg). These files will serve as introductory exercises to show the user how to work with the custom nodes.
In Dynamo, begin by clicking Packages>Publish New Package...
In the "Publish a Dynamo Package" window, we've filled out the relevant forms on the left of the window.
- By clicking "Add File", we've also added the files from the folder structure on the right side of the screen (to add files which are not .dyf files, be sure to change your file type in the browser window to "All Files(.)". Notice that we've added every file, custom node (.dyf) or example file (.dyn), indiscriminately. Dynamo will categories these items when we publish the package.
- The "Group" field defines which group to find the custom nodes in the Dynamo UI.
- Publish by clicking "Publish Locally". If you're following along, be certain to click "Publish Locally" and not "Publish Online"; we don't want a bunch of duplicate packages on the Package Manager.
- After publishing, the custom nodes should be available under the "DynamoPrimer" group or your Dynamo Library.
Now let's look at the root directory to see how Dynamo has formatted the package we just created. Do this by clicking Packages>Manage Packages...
In the manage packages window, click on the three vertical dots to the right of "MapToSurface" and choose "Show Root Directory".
Notice that the root directory is in the local location of your package (remember, we published the package "locally"). Dynamo is currently referencing this folder to read custom nodes. It's therefore important to locally publish the directory to a permanent folder location (ie: not your desktop). Here is the Dynamo package folder breakdown:
- The bin folder houses .dll files created with C# or Zero-Touch libraries. We don't have any for this package so this folder is blank for this example.
- The dyf folder houses the custom nodes. Opening this will reveal all of the custom nodes (.dyf files) for this package.
- The extra folder houses all additional files. These files are likely to be Dynamo Files (.dyn) or any additional files required (.svg, .xls, .jpeg, .sat, etc.).
- The pkg file is a basic text file defining the package settings. This is automated in Dynamo, but can be edited if you want to get into the details.
Publishing a Package Online
Note: please do not follow along with this step unless you are actually publishing a package of your own!
- When you're ready to publish, in the "Manage Packages" window, select the button the right of MapToSurface and choose Publish...
- If you're updating a package that has already been published, choose "Publish Version" and Dynamo will update your package online based on the new files in that package's root directory. Simple as that!
Publish Version...
When you update the files in your published package's root folder, you can publish a new version of the package by selecting "Publish Version..." in the Manage Packages window. This is a seamless way to make necessary updates to your content and share with the community. Publish Version will only work if you're the maintainer of the package.


Selection Structures
Decision making via conditional statements is an important building block in algorithm design; Selection is used to control the flow of execution of a program.
Conditional Statements
Conditional statements in Python include:
if
statementif....else
statementsif....elif....else
statements
Conditional statements are logical expressions that evaluate as TRUE or FALSE and using these results to perform further operations based on these conditions.
Nearly all flow control in a program depends on evaluating conditions. The program will proceed diferently based on the outcome of one or more conditions - really sophisticated AI programs are a collection of conditions and correlations.
Expressed in a flowchart a block if
statement looks like:
As psuedo code:
if(condition is true):
do stuff
Amazon knowing what you want is based on correlations of your past behavior compared to other peoples similar, but more recent behavior, and then it uses conditional statements to decide what item to offer you in your recommendation items. It's a bit spooky, but ultimately just a program running in the background trying to make your money theirs.
Comparison
The most common conditional operation is comparison. If we wish to compare whether two
variables are the same we use the ==
(double equal sign).
For example x == y
means the program will ask whether x and y have the same value.
If they do, the result is TRUE if not then the result is FALSE.
Other comparison signs are !=
does NOT equal, <
smaller than, >
larger than, <=
less than or equal, and >=
greater than or equal.
There are also three logical operators when we want to build multiple compares
(multiple conditioning); these are and
, or
, and not
.
The and
operator returns TRUE if (and only if) all conditions are TRUE.
For instance 5 == 5 and 5 < 6
will return a TRUE because both conditions are true.
The or
operator returns TRUE
if at least one condition is true.
If all conditions are FALSE, then it will return a FALSE. For instance 4 > 3 or 17 > 20 or 3 == 2
will return TRUE
because the first condition is true.
The not
operator returns TRUE
if the condition after the not
keyword is false. Think of it
as a way to do a logic reversal.
# Examples
Block if
statement
The if
statement is a common flow control statement.
It allows the program to evaluate if a certain condition is satisfied and to perform a designed action based on the result of the evaluation. The structure of an if
statement is
if condition1 is met:
do A
elif condition 2 is met:
do b
elif condition 3 is met:
do c
else:
do e
The elif
means "else if". The :
colon is an important part of the structure it tells where the action begins. Also there are no scope delimiters like (), or {} .
Instead Python uses indentation to isolate blocks of code.
This convention is hugely important - many other coding environments use delimiters (called scoping delimiters), but Python does not. The indentation itself is the scoping delimiter.
# Examples
Inline if
statement
An inline if
statement is a simpler form of an if
statement and is more convenient if you
only need to perform a simple conditional task.
The syntax is:
do TaskA `if` condition is true `else` do TaskB
An example would be
myInt = 3
num1 = 12 if myInt == 0 else 13
print(num1)
13
An alternative way is to enclose the condition in brackets for some clarity like
myInt = 3
num1 = 12 if (myInt == 0) else 13
print(num1)
13
In either case the result is that num1
will have the value 13
(unless you set myInt to 0).
Example: Light Pipes
If light is directed into one end of a long glass or plastic rod the light is totally reflected by the walls bounging until it reaches the end of the rod. Light pipes use this optical phenomenon to transmit light and even images from one place to another. If one bends a light pipe the light can be coaxed to follow the pipe and curve around corners -- if the pipes are bundled into a collection of fibers mutiple signals can be sent down each fiber and these bundles are the main component of optical fiber communication and is schematized in the figure below.
The total internal reflection can be predicted using Snell's law and the indices of refraction of the fiber and jacket materials. Usually the core material is selected with a high refractive index compared to the jacket (which may be just air). When light passes from one material to another it is bent at the interface proportional to the refractive indices and the angle of incidence at the interface as in the sketch below
The angle of incidence where the light will reflect as opposed to crossing the interface is called the critical angle and is subject to the formula:
where is the refractive index of the fiber core and is the refractive index of the jacket.
If the jacket has a higher refractive index than the core, the light pipe will not transmit light from one end to another regardless of the incidence angle. If not, then any incidence angle greater than the critical angle (e.g. closer to the pipe entry axis) will sucessfully achieve internal reflection and transmit.
Suppose we wished to make a design tool to let designers evaluate different materials and determine if a particular material selection makes sense, and how small an angle will work (smaller means less precision is required at the entry/exit interface). Lets apply the problem solving protocol, and a bit of computational thinking to develop a tool.
Step 1 Problem Statement: Determine whether a light pipe constructed of two materials will transmit light that enters the pipe at a prescribed angle
Step 2 Input/Output/Governing Principles Inputs are the indices of refraction of the core () and jacket() materials and the light incident angle at the pipe entrance ()
The governing equations are
and
Step 3 By-Hand Example Consider a core made of optical glass (without coatings) surrounded by air - a pipe without a jacket. The refraction index for air is 1.0003. The index of refraction for glass is 1.52
The critical angle is
Thus the light pipe will transmit all light that enters at an angle greater than 41.15 degrees.
Step 4 Algorithm Development The problem is decomposed as
- Read into the application the refraction indices and and the incidence angle relative to the core/jacket wall.
- Determine if is larger than , if true then no transmission
- If transmission is possible, then compute critical angle
- Determine if incident angle larger than critical angle, if true then transmission
- Report result
As psuedocode:
- prompt user for n1,n2,angle
- if n2>n1 print no transmission else
- compute critical angle
- if incident angle > critical angle then print transmission
- else print no transmission
Below we convert psuedocode to python script
# load the math library
import math
# prompt user for n1,n2,angle
print('Begin Light Pipe Design')
n1 = float(input('Enter RI of pipe core'))
n2 = float(input('Enter RI of pipe jacket'))
anglein = float(input('Enter incident angle of light (in degrees)'))
# if n2>n1 print no transmission else
if (n2>n1): # selection structure
print('Light not transmitted, jacket material too dense')
else:
# compute critical angle
critangle = math.degrees(math.asin(n2/n1)) #use math package for arcsine
# if incident angle > critical angle then print transmission
if anglein > critangle: # selection structure
print('Light is transmitted')
# else print no transmission
else:
print('Light is not transmitted, adjust interface angle')
print('End Light Pipe Design')
Begin Light Pipe Design
Enter RI of pipe core 1.52
Enter RI of pipe jacket 1.0003
Enter incident angle of light (in degrees) 45
Light is transmitted
End Light Pipe Design
Now we have a tool and can evaluate a variety of material pairs to build a light pipe.
| Material | Index of Refraction |
|---|---|
| Hydrogen (1 atm.;0C) | 1.0001 |
| Air (1 atm.;0C) | 1.0003 |
| Carbon Dioxide(1 atm.;0C) | 1.0005 |
| Water (20C) | 1.333 |
| Ethanol (20C) | 1.362 |
| Glycerine (20C) | 1.473 |
| Ice | 1.31 |
| Polystryene | 1.59 |
| Crown Glass | 1.62 |
| Borosilicate | 1.75 |
| Carbon (Diamond) | 2.417 |
| Acrylic | 1.49 |
Step 5 Testing/Application Apply using acrylic in water
# load the math library
import math
# prompt user for n1,n2,angle
print('Begin Light Pipe Design')
n1 = float(input('Enter RI of pipe core'))
n2 = float(input('Enter RI of pipe jacket'))
anglein = float(input('Enter incident angle of light (in degrees)'))
# if n2>n1 print no transmission else
if (n2>n1): # selection structure
print('Light not transmitted, jacket material too dense')
else:
# compute critical angle
critangle = math.degrees(math.asin(n2/n1)) #use math package for arcsine
# if incident angle > critical angle then print transmission
if anglein > critangle: # selection structure
print('Light is transmitted')
# else print no transmission
else:
print('Light is not transmitted, adjust interface angle')
print('End Light Pipe Design')
Begin Light Pipe Design
Enter RI of pipe core 1.49
Enter RI of pipe jacket 1.333
Enter incident angle of light (in degrees) 45
Light is not transmitted, adjust interface angle
End Light Pipe Design

Pair programming is when two developers tackle a challenge together. This can be either done on site or remotely using video chat technologies. The benefits of pair programming are numerous. Primarily, it can be beneficial to have more than one mind working on the same problem. Different people bring different backgrounds and experiences to a challenge, and may offer a different or cleaner solution. Obviously, this can also be challenging since it requires two people to work together under sometimes stressful circumstances. In order to maintain order during a pair, its important to identify a drive and a navigator. These terms are compared below.
Driver
The driver is the one typing the code and following the direction of the navigator. The driver does not need to be totally silent, but can ask questions and offer input and ideas as well.
Navigator
The navigator is responsible for double checking syntax and keeping an eye on the overall goal. The navigator guides the drivers typing.
Not only is pair programming useful for tackling technical challenges, but it can also be a great way to connect and communicate with other devs. Learning to code can be very stressful and often leads to fears of inadequacy and a sense of being lost. Pairing allows devs to check in with one another and connect in powerful ways to reduce those fears.
Beyond DBC, pair programming can teach devs the soft skills necessary to become a vital part of any dev team. In the web development world, designers need to be able to work as a team with other designers who come from a wide variety of backgrounds and skillsets while maintaining professionalism. In short, Pair programming at DBC prepares devs for a career as a web developer.
Reflection
We really enjoyed pair programming, working together seemed easier than we thought and much more enjoyable than imagined. This was Tam's first pairing and went much better than imagined. It was the first time collaboratively writing anything for both of us. What worked was using screen sharing and communicating well. Collabedit was difficult to use for the switching back and forth.
We tried to use dev tools but that didn't seem to work well. We went back to the old school way. It was easier to copy and paste back to sublime the old way.
