This introduction reflects parts of the C4 Model (https://c4model.com) with Context, Containers, and Components. The Code is described in separate chapters.
The Overview and Context is a top-level view of the context and the problem domain.
The Actors provides some additional background on the actors in the various use cases.
The Use Cases provides more detailed narratives on each use case.
The Container Overview describes the various containers for software components.
The Component Architecture lists a number of components and some ways they interact.
There are Other Notes and References with additional details.
Overview and Context¶
The essential stories are these:
“As skipper of S/V Red Ranger, I need to create detailed voyage plans with distance, bearing, and estimated time of arrival to each mark or waypoint.”
“As a monitor of S/V Red Ranger, I need to know if the vessel is make progress accoring to plan, so I can help with rescue efforts if there is a problem.”
To put these stories into context, we have a number of tools for voyage planning, execution, and analysis. This software fills some essential gaps among those tools.
These fit into three broad areas: Planning, Execution, and Analysis.
Planning. Voyage planning involves locating courses that avoid navigational hazards and make use of the available Aids to Navigation (ATONs). In some cases, tide and current are accounted for, as well as adverse weather.
For route planning, S/V Red Ranger relies on OpenCPN (https://opencpn.org). This supports createing waypoints and routes. It can create GPX and CSV files that can be shared with chartplotters, and individuals who monitor the voyage.
It’s not a good idea to sketch a route on an electronic chart and copy the details to create a schedule for sailing. Trying to do this manually is likely to introduce transcription errors. OpenCPN can produce a CSV file of sailing details; this is difficult to work with because the data is highly formatted for human readability. OpenCPN can produce a GPX file, but it lacks bearing and distance information required to be useful.
Execution. For sailing a particular voyage, S/V Red Ranger carries several ways of assuring that she is on course.
Crew observation of the ATONs, landmarks, and seascape.
Electronic Chartplotter in the cockpit. (B&G Zeus2)
Backup Chartplotter at the nav station. (Standard Horizon CP180i)
iNavX on a iPhones and iPad (http://www.inavx.com). These use a separate Dual XGPS 150 antenna (http://gps.dualav.com/explore-by-product/xgps150a/).
OpenCPN on a MacBook Pro. (http://opencpn.org)
Paper charts and standard piloting techniques like dead reckoning, lines of position and course lines.
This is used to be sure S/V on course.
Additionally, notifications are made via a Spot Messenger (https://www.findmespot.com/en-us/). Beyond this, the AIS transponder on Red Ranger can be monitored by Marine Traffic (https://www.marinetraffic.com/en/ais/details/ships/shipid:4840133/mmsi:367449760/imo:0/vessel:RED_RANGER/_:bc5a3f5a398b45a0c5c45e4dc2d3ce02) These two mechanisms assure that a monitor can notify authorities of Red Ranger fails to check in.
The cockpit chartplotter provides an Estimated Time of Arrival (ETA) to a specific waypoint based on current course and speed. It fails to provide the planned ETA to subsequent waypoints.
When deviating from the original plan, additional details are required, and the Chartplotter may be used to create new routes.
Contingency planning during a voyage is related to the following advice:
“The most dangerous piece of equipment is the calendar. The issue here is not maintaining a schedule, but sailing safely during daylight hours and leaving enough time to locate an anchorage before dark.”
Analysis. There are two essential types of retrospective analysis. One is to analyze logs. The ther is to reconcile route and waypoint changes made along the way.
Logging is done several ways.
The Chartplotter in the cockpit can record a track.
The backup chartplotter in the nav station can also record a track. It’s a little more difficult to extract data from this chartplotter.
OpenCPN on a MacBook Pro with its own GPS antenna can record a track. This is not currently feasible on Red Ranger: there’s no way to secure the computer or provide power.
iNavX on an iPhone or iPad with a separate GPS antenna. This also requires leaving the phone running. The track can be extracted through the X-Traverse web site, an awkward intermediate step.
Paper logging of heading, speed, wind and engine for each sail change, tack and each hour. This is currently how track analysis is handled.
Analysis of waypoint changes requires identifying a single source of the truth for waypoints and then distributing the waypoints to the various devices. The OpenCPN computer seems best for this, since it’s also used for planning and creating new waypoints.
The chartplotters can have waypoints transferred to them from the computer via GPX files or the USB-based NMEA-0183 interface. This makes the computer the source of truth.
Actors¶
The primary actor for the use cases is the Skipper of S/V Red Ranger. Crew members may participate in the Execution. However, the ultimate responsibility lies with the skipper.
Voyage planning can be forwarded to shore Monitor in the form of a Float Plan Document. Using SPOT Messenger satellite communications, we can provide actual positions so that the shore crew can compare positions against the voyage plan.
The Chartplotter and OpenCPN application on the computer are other, external systems, and therefore actors in these use cases. They aren’t autonomous, and some manual intervention is required to exchange waypoint and route information between these actors and the navtools system described here.
Analysis is done to make sure that subsequent plans use the best available information.
Use Cases¶
There are a number of use cases for navtools. Each has some supporting details:
Planning Use Case¶
The overall planning use case creates a a waypoint-by-waypoint schedule or “Voyage Track”. See Bowditch [bowditch], section 2508, Constructing a Voyage Track. Also, see Bowditch [bowditch], section 802 for more information on planning.
- bowditch(1,2,3)
THE AMERICAN PRACTICAL NAVIGATOR. http://www.irbs.com/bowditch/ Also http://msi.nga.mil/MSISiteContent/StaticFiles/NAV_PUBS/APN/pub9.zip
Generally there are two steps to this.
Track Planning.
Actor plans the route in general with OpenCPN.
OpenCPN saves the route as a list of waypoints.
Voyage Details.
Actor extracts the route details from OpenCPN. There are three variations on creating a schedule from a route.
Extract a route file in GPX and run
navtools.planning
. This can also be downloaded to the Chartplotter. See Route Document Use Case for details.Extract a planning table in CSV and run
navtools.opencpn_table
.
System creates a “schedule” file with the waypoints plus additional information like distance to next waypoint, bearing of next waypoint, and ETA.
The actor can perform this use case multiple times to create alternatives and contingency plans.
Float Plan Document Use Case¶
This is a variation on the basic Planning Use Case. It involves an extra step:
Actor extracts the route details. System creates a “schedule” file with the waypoints plus additional information like distance to next waypoint, bearing of next waypoint, and ETA. There are two variations on creating a schedule from a route.
Extract a route file and run
navtools.planning
.Extract a planning table and run
navtools.opencpn_table
.
Actor runs a spreadsheet application (Open Office Org, for example), and imports the schedule file. The schedule is transformed into a Float Plan.
The Float Plan document includes boat description, US CG locations and phone numbers.
Route Document Use Case¶
This is a variation on the basic Planning Use Case. This is how the route information arrives at the Chartplotter.
Actor extracts the route details from OpenCPN in GPX format.
This is downloaded to the Chartplotter.
This involves transferring the GPX file to a MicroSD card and the importing the route to the chartplotter.
Execution Use Case¶
Consider a sample sailing story for the “Check Schedule” step in the diagram above.
Actors depart their slip for a destination that involves \(n > 2\) waypoints.
System (cockpit chart plotter) shows ETA to waypoint 1. Actors arrive at waypoint 1, switch system to waypoint 2.
System shows ETA to waypoint 2. Actors arrive at waypoint 2, switch system to waypoint 3.
System shows ETA to waypoint 3. Actors realize that arrival time is now unsafe (i.e., after dark).
At waypoint 1 – due to adverse wind or currents – Red Ranger could have been behind the overall schedule, and the actors needed to know this before setting course for waypoint 2.
This means that waypoint-by-waypoint planned ETA’s are required for safe execution of a schedule. The skipper can then compare planned ETA’s with actual ETA’s to determine if contingency plans should be executed.
A “Check Schedule” could replace the current route with a new route. While the details of the route and waypoints have changed, the general use case remains in “Execution” mode until Red Ranger is docked, moored, or anchored safely.
Notifications Use Case¶
This can be a transfer of information from Red Ranger to the Monitor. There are several steps; this is closely related to the “Execution” use case.
We can think of this as two sequences of steps.
Skipper uses the Spot Messenger to post an OK message at a time noted on the Float Plan. This is generally noon US East local time.
Messenger posts the message to the Monitor.
The Monitor must now compare the notification against the Float Plan.
This can also be a failure to transfer information from Red Ranger.
Red Ranger is delayed or has more serious problems: no message is sent.
The Monitor must look at the Float Plan to note that a check-in is missing.
Ideally, the first use case is the only one exercised. The second use case is a rare situation.
Analysis: Summary Use Case¶
In retrospect, a track may be analyzed to compute actual distance run (and times of arrival). This can be compared with the plan to improve the quality of the planning process.
The essential feature is analysis of the track created by the GPS chartplotter (or computer) during sailing.
There are two ways to initiate this:
Actor extracts the track from the GPS chartplotter. System saves the track as a list of positions and times, generally in GPX format.
Actor manually enters log pages into a spreadsheet to create a CSV file.
Actor runs the
navtools.analysis
application. System creates a CSV file with the track position plus additional information like distance to next position, cumulative time and cumulative distance.Actor runs a spreadsheet application (Open Office Org, for example), and imports the analysis results.
Analysis: Waypoint Reconciliation Use Case¶
In retrospect, waypoints (and routes) may be changed when voyaging. The chartplotter’s data must be compared with the original data on the computer to make sure the computer has the complete list of known good waypoints.
Actor dumps charplotter-unique waypoints. These are not on the computer, which is the single source of truth. Chartplotter provides a file.
Actor dumps OpenCPN waypoints. OpenCPN provides a file.
Actor runs the
navtools.waypoint_merge
application. System creates a GPX file with new and changed waypoints. Ideally GUID’s are used to manage changes. If necessary, changes can be performed with a “to be added” and “to be deleted” list. Because removing a waypoint can break routes, an incremental set of changes is available to fix routes before deleting changed waypoints.Actor merges the waypoints, loading new and changed waypoints to OpenCPN.
Actor makes manual edits and updates waypoints and routes to cleanup and simplify. The OpenCPN data can be used to download new routes and waypoints to the chartplotter.
Additional Steps:
Dump chartplotter-unique routes (if any.) These are not on the computer.
Merge the routes into OpenCPN. Make any manual edits.
Merging routes makes the computer the source of truth for planning.
Container Overview¶
The interaction among containers looks like this:
The core planning tool is OpenCPN on an iMac. This application can export a route file in GPX or CSV notation.
The core execution tool is the Chartplotter running on S/V Red Ranger. This can import route files in GPX notation. It can export Waypoints in USR or GPX notation.
The GPX, USR, or CSV files can be imported and parsed by a Python application, which can use a set of navigation calculations to compute range, bearing, time for each leg. It can also compute an accumulated time and accumulated distance.
The Python application can emit CSV files for use in other desktop tools. A spreadsheet can be used to print a paper schedule is used for cockpit decision-making. The actual time of arrival (ATA) to each waypoint can be logged. The gap between ETA and ATA supports a number of sailing decisions.
A spreadsheet can be emailed to support a float plan. And a spreadsheet can be used for retrospective analysis of voyages.
Data Interface¶
The application reads GPX, USR or CSV files and writes CSV files for spreadsheets or GPX files for exchange between chart plotter and computer.
Some additional configuration parameters are also required as part of planning. For example, the anticipated speed of the boat on each leg of the course. This – in principle – can vary by leg depending on conditions and desired arrival times.
In a sailboat, a single default value makes the most sense. A displacement hull (like S/V Red Ranger) has \(1.34\times\sqrt{LWL} = 8.2\) is the maximum hull speed. A more useful default sailing speed is 5.5 kn; this reflects well-trimmed sails in a 10-15 kn breeze.
User Interface¶
The applications are essentially simple “filter”-like applications. Consistent with the *nix philosophy, the interface is a CLI that reads a file or standard input and writes a file.
Here’s a concept of how this might be used.
The following creates a my_trip Schedule.csv
file with the schedule
calculations. This can be loaded into a Numbers spreadsheet.
python -m navtools.planning my_trip.gpx
The following creates a some_log Distance.csv
file with the distance
and speed calculations from the logged data. This can be loaded into a Numbers spreadsheet
for future voyage planning.
python -m navtools.analysis some_log.csv
The following converts an OpenCPN route plan into a useful form for Numbers to work with.
python -m navtools.opencpn_table plan.csv
The following merges waypoints from the Chartplotter and OpenCPN into a single GPX-format file that can be used to update OpenCPN.
python -m navtools.waypoint_merge -p plotter.usr -c opencpn.gpx --by name --by geocode --report gpx
Component Architecture¶
There are several layers to these applications.
The following component descriptions provide additional details of the relationships.
navtools.navigation
module defines the domain objects and functions. This includes GPS coordinates, range and bearing calculations.navtools.igrf
module performs compass deviation calculations.The GPX or CSV input file parsing is conceptually separate, but these are small transformation functions built around
xml.etree
andcsv
; they aren’t broken out into separate, tiny modules. These components create navigation objects from an input file.navtools.lowrance_usr
module creates navigation objects from an input file produced in USR format from a chartplotter.navtools.olc
creates Geocodes from latitudes and longitudes. This implements the core of Open Location Code (OLC) Geocoding. (Note: It doesn’t fully decode OLC back to Latitude/Longitude.)navtools.solar
computes sunrise and sunset. This lets us know if an arrival or departure time is in daylight or night.The “main” applications have the CLI interface and processing. Each of these opens one (or more) files, performs the navigation calculations, and creates the output file. This may be a schedule or analysis spreadsheet-friendly CSV files. It can also create an upload-ready GPX file.
The intent here is to decompose any problem into a number of pieces:
Input parsing (USR, CSV, GPX, etc.)
Navigational computations: distance, bearing, deviation, duration, etc.
Output creation (CSV, GPX)
An overall CLI.
These conceptual layers to each application leverage classes within the component modules.
Other Notes¶
This application is not “plugged into” OpenCPN, iNavX, or the NMEA 2000 bus on Red Ranger. Consequently, planning involves multiple steps with multiple tools. A route is created, the ETA’s examined, and waypaints added to handle overnight anchorages. Any change to a waypoint means the schedule must be recalculated.
Additional inputs could include details from the serial interface. A USB GPS antenna (Like the BU-535) can be read via PySerial to supply data to OpenCPN.
A Bluetooth GPS antenna (like the Dual XP150 Bluetooth GPS receiver) can also be used to provide details to OpenCPN.
Annotations that can be included on the paper chart route plan (like ATON details, for example) aren’t present in these schedule documents. The details aren’t in the source GPX files from OpenCPN or the chartplotter.
To an extent, additional resources, like the online light list http://www.navcen.uscg.gov/?pageName=lightLists could be consulted to provide additional route and waypoint information. Locating the lights passed along the track as well as lights near each waypoint is challenging. In principle, each light can be geocoded and located near waypoints.

Our empirical study aims to answer the following research questions:
You can download the following datasets for research purposes.
Note: The empirical dataset is only applicable for personal usage.To answer this research question, we need to collect a list of callback APIs and study how they evolved.
In total, we collected 2,589 callback APIs to form the callback API list. We further refer to the code commits in AOSP to study the updates of callback APIs, and categorized them into two groups: reachability change and API behavioral modification.
Click here to download and view the list of callback APIs.
To understand how callback API evolutions can induce compatibility issues in real Android applications, we investigated 100 callback compatibility issues from 50 open-source projects on GitHub.
We further analyzed the online discussions, issue patches, and issue git commits to understand the practices of app developers to fix issues.
We categorized issues into two categories: CCFG structural changes and CCFG non-structural changes.

CreateMirror ( [parent] )
Parameters:
| parent - parent entity of mirror |
Description:
| Creates a mirror entity and returns its handle. A mirror entity is basically a flat, infinite 'ground'. This ground is invisible, except it reflects anything above it, below it. It is useful for games where you want have the effect of a shiny floor showing a reflection. For a true shiny floor efffect, try combining a mirror entity with a textured plane entity that has an alpha level of 0.5. The optional parent parameter allow you to specify a parent entity for the mirror so that when the parent is moved the child mirror will move with it. However, this relationship is one way; applying movement commands to the child will not affect the parent. Specifying a parent entity will still result in the mirror being created at position 0,0,0 rather than at the parent entity's position. See also: CreatePlane. |

Package org.dellroad.stuff.schema
Features include:
- Automatic initialization of the database schema when the application runs for the first time
- Automatic application of database schema updates as needed during each application startup cycle
- Automated tracking and constraint-based ordering of schema updates supporting multiple code branches
- Integration with Spring allowing simple XML declaration of updates
- An ant task that verifies schema update correctness
See SpringSQLSchemaUpdater
for an example of how to declare your
DataSource
and associated schema updates in a Spring application context.
Updates may have ordering constraints, and these should be declared explicitly. Once you have done so, then you may safely "cherry pick" individual schema updates for merging into different code branches without worrying whether the schema will get messed up, because any ordering constraint violations will be detected automatically. This verification step is required to detect inconsistencies between the updates and the current code.
See DellRoad Stuff's ant macros for the schemacheck
ant macro that can be used to verify that your delcared schema updates, when applied to the original schema,
yield the expected result (which is typically generated automatically by your schema generation tool from
your current code). It is also a good idea to compare your generated shema matches to an expected result
during each build to detect schema changes caused by e.g., inadvertent changes to model classes.

FROM: DR, ADAMS OBOZUWA. TEL/FAX: 234 1 759 0379<EMAIL_ADDRESS>TEL/FAX: 234 1 759 0379. BUSINESS PROPOSAL Dear sir / Madam My name is DR, ADAMS OBOZUWA., a member of the Presidential Task Force on Oil Spillage Clean-up. Early last year there was a major oil spillage in the Niger Delta Region of Nigeria which rendered over 70% of the communities homeless.The contract was handled by a foreign firm but because of the huge monetary profit we envisaged we decided to over-invoice the contract sum. Now the contract has been completed and the original contractor has since been paid,but the contract balance of US$38 million,which resulted from the over invoiced contract sum that has been left in a suspense account with the DEBT RECONCILIATION COMMITTEE A SUBSIDIARY OF THE APEX BANK,is what me and my partners are planning to take out of the country for ourselves.The problem is as government officials,we are not suppose to own fat bank accounts,talk less of having foreign ones.To this end, we are soliciting your assistance as a foreign partner who can assist us and receive this amount into your account. We are ready to share this money with you on the basis of participation. We also have plans to invest part of this money in any viable business in your country under your care,as we are nearing our retirement age. In any case, I received a reference of you/organization from the Nigeria Chambers of Commerce and Industry ‘Foreign Trade Division’ as a reputable organ that can assist us on this transaction.

It does not matter whether you or your company does contract project of the nature described here, the assumption is that you won a major contract and subcontracted it to another company, more often than not, big trading companies or individuals of unrelated field win major contracts here in Nigeria and subcontracts same to more specialized firms for execution. BENEFIT For providing the account where we shall remit this money, you will be entitled to 25% of the entire funds, 70% will be for me and my partners,while 5% has been set aside to cover any expenses that may be incurred by both parties during this transaction, both local and international. Please I enjoin you to handle this transaction with utmost degree of maturity and confidentiality because I am still in active government service with the “NIGERIAN NATIONAL PETROLEUM CORPORATION”. If I receive your response on time, this whole transaction could be accomplished within the shortest possible time based on your interest and determination,since the money is already in transit.

Deontay Wilder wears bizarre outfit ahead of heavyweight rematch with Luis Ortiz
Wilder takes on Ortiz for a second time on Saturday when he defends his heavyweight world title in Las Vegas
by Martin Domin, https://www.facebook.com/mirrorfightingDeontay Wilder made quite the impression as he arrived in Las Vegas ahead of his heavyweight rematch with Luis Ortiz.
The world champion defends his title against Ortiz on Saturday night, 18 months since he was rocked by the Cuban before stopping the 40-year-old in the 10th round.
And as he arrived bare-chested in Sin City, Wilder promised to finish the job in double-quick time.
"We're all here to see what's going to happen on Saturday night," he said.
"Even though I knocked Ortiz out the first time, it was an amazing fight. That was the fight that I was challenged the most during. I understand why none of the other heavyweights want to fight Ortiz.
"He's very dangerous and I blessed him with a second chance.

Mirror Fighting has launched a new weekly boxing show in association with Betfair in which we analyse the latest big fights, play matchmaker, and preview forthcoming bouts.
Former super-middleweight world champion George Groves provides expert analysis.

"Fans always get their money's worth when I'm on the big stage because people know what I'm able to do to another human being inside of that ring. I can't wait for Saturday night."
Ortiz has recorded three routine victories since he lost to Wilder - his first and only defeat as a professional.
And despite his advancing years, he is confident of upsetting the odds.
"Deontay Wilder is a throwback fighter like me, and we both want to fight the best," he said.
"I believe I'm the best and that's why I'm getting this rematch. I'm focused on this fight and this fight only and doing everything to have my hand raised Saturday night.
"My life has changed tremendously and for the better since I came to the United States from Cuba.
"Being in the US has allowed me to focus on my two dreams, finding a cure for my daughter's disease and becoming heavyweight champion of the world. That's always been my mission."

Kepler Communications is a satellite communications company that is working towards establishing an in-space telecommunications network for space-borne assets. Put simply, we are building cell phone towers in space. This infrastructure will resolve the problem of intermittent connectivity for non-geostationary satellites, will open new business opportunities that necessitate real-time connectivity to satellites, and will reduce reliance on costly and difficult to deploy ground infrastructure.
An infrastructure venture is no simple feat, particularly true for space-based infrastructure. To reach this long-term objective, tangible shorter-term milestones are planned in order to incrementally develop the technologies and deploy the infrastructure necessary to execute on this vision. Each milestone towards this vision represents a viable business opportunity, enabling Kepler to sustainably realize this vision.

Zinedine Zidane urges Real Madrid fans to stop jeering Gareth Bale
The Wales forward was sent on for the closing stages with whistles ringing in his ears.
Head coach Zinedine Zidane hopes Real Madrid fans will not give Gareth Bale a hard time for too long.
The Wales forward came off the bench to a chorus of jeers before helping Real Madrid seal a 3-1 win over Real Sociedad at the Bernabeu.
Bale was sent on for the closing stages with whistles ringing in his ears, following the latest country versus club row during the international break.
The former Tottenham man, though, kept his cool to send over a deep cross which led to Luka Modric wrapping things up with a third goal.
Bale had been criticised in Spain after being pictured celebrating Wales’ Euro 2020 qualification victory over Hungary in midweek with a flag which read “Wales. Golf. Madrid. In that order”.
Zidane, though, called for a sense of perspective after the forward produced a determined display, Real Madrid recovering from a terrible start when Willian Jose punished a poor defensive backpass from captain Sergio Ramos.
“I hope this doesn’t carry on for the rest of the season,” Zidane said in quotes reported by Marca. “We want the fans to be with us from the beginning to the end, but we cannot control that,” the Real Madrid coach said.
“The public has the right to do what they want, but I ask that they applaud everyone. I’m happy with the game and the victory and Bale came into the game well.
“What you have to do is keep working on the pitch.”
Zidane added: “I have not spoken to him (about the jeers), I have only congratulated him.
“I can’t tell you if it’s unfair or not. Everyone can say what they want. We need our fans, then we can’t control what happens.
“There is too much noise with Bale, he wants to be with us and do it well. That is why we don’t want to talk so much.
“He is integrated into the group and wants to play, just like everyone else.”
After Real recovered from their poor start, Karim Benzema equalised from Luka Modric’s free-kick, before a deflected shot from Federico Valverde put the home side in front soon after the restart.
Zidane felt his team had responded well, now back level on points with LaLiga leaders Barcelona.
“We didn’t start well with the ball, we were very slow. Then, the end of the first half was very good and the start of the second half also,” the Real Madrid coach said.
“There was a very good team playing against us, so we are happy for the three points.”
Real Madrid have little time to regroup as they host Paris St Germain in the Champions League.
“What we want is to play a great game. We have to rest well, because this game has taken a lot from us,” Zidane said.
Real Sociedad coach Imanol Alguacil was left to reflect on what might have been.
“I am happy with the first part of the match, and I think we deserved more, although Real did have eight very good minutes,” he said.
“We have had opportunities and if we had taken them, the mood would have been different.
“We had clear options to make goal. I’m happy because the team has pressed on our rival’s goal throughout the match.”

[gecode-users] MemoryStop - is there any replacement
Helmut Jarausch
jarausch at skynet.be
Wed Aug 10 11:28:11 CEST 2016
Hi,
I'd like to use gecode-python for interfacing Gecode to Python - or is
there some more up-to-date binding?
gecode-python uses in its interface file gecode-common.icc the
following code
Search::MemoryStop * memory_stop;
but gecode-4.4.0 doesn't have any declaration of that type anymore.
Is there a replacement for that - or how can I upgrade gecode-python ?
Many thanks for some hints,
Helmut

There may be some nested scopes between the ui-scroll and the controller where you want the adapter object to be injected. As it follows from the documentation,
adapter="expression on controller" format can be used to explicitly specify the scope associated with the specified controller as the target scope for the injection.

{{item}}

In this sample we have ng-if wrapper over the viewport which causes an intermediate scope. "Is loading" will not work without specifying the controller through the "on controller" syntax .

Unless otherwise specified, all bounds are for nonadaptive linear LCC’s/LDC’s. What about adaptive codes?
Let \(\de,\ep\in (0,\rc2]\), \(q\ge 2\).
Families
A matching vector family in \((\Z/(p-1))^m\) of size \(n\) gives a \((p-1)\)-query LDC \((\Z/(p-1))^m \to (\Z/(p-1))^m\). There is also a trick to reduce the number of queries (e.g. to 3).
Construction: Given \((v_i)\), the encoding is \[(a_i)\mapsto f=\sum_i a_j x^{v_j}.\] (\(x\) is a vector in \(\F_p^{\times n}\).) Recovery works by taking a primitive \(g\) and summing \(f(g)+\cdots + f(g^{p-1}) = a_i\) by orthogonality of characters.
Motivation: Ordinary Reed-Muller codes are \[(a_d)\mapsto \sum a_d x^d.\] We modify by replacing \(x\) by an element in \(\F_p^{\times}\).
A \((q,\ep,\de)\), \(k\to n\) LDC consists of
Let \(\mu_i(x)=\EE_{t\sim M_i} D_{i,t}(x)\), \(\mu(x)=(\mu_1(x),\ldots, \mu_k(x))\).
Can we assume WLOG there is perfect decoding of codewords? \(D_i(C(x))=x_i\).
If we can, then \(\{-1,1\}^k\subeq \im \mu\). Otherwise, we still have: for each \(x\in \{-1,1\}\), there is \(x'\) with \(\sgn(x')=\sgn(x)\) such that \(|x_i'|\ge \rc2 + \ep\).5 (If there is \(\mu\) such that this is true, does that mean we can make a LDC out of it? Yes—send the messages to the preimages of those points.)
The picture to have in mind: \[\{\pm 1\}^k \xra{C} \{\pm 1\}^n \xra{\text{noise}} \{\pm 1\}^n \xra{\mu} [-1,1]^k\] (\(\mu\) is the average decoding according to \(D\).)
It is necessary for \(\im \mu\) to have a large \(\ep\)-net. Otherwise it can’t contin \(\{-1,1\}^k\). Thus we can show lower bounds by showing any \(\im\mu\) has a small \(\ep\)-net. Think of this as a communication complexity problem: Alice wants to communicate \(\mu(y)\) to Bob with \(\ep\) accuracy without sending many bits. (Be careful about \(\ep\) vs. \(\eph\) here.)
Lemma: If there is an \(\ep\)-net of size \(s\), then \(\ln s \ge \pa{1-H\pa{\eph}}k\). (Generalization \(p\)-norm: \(\ge \pa{1-H\pf{\ep^p}2}\).)
Thus if \(s= n^{O_\ep(1)}\) then we get an exponential lower bound.
A random matching should not work. Can we generalize to a larger class of mappings that don’t work? Yes, if we have the property, say, that every set of \(\Om(\ln n)\) of the matchings form an expander, because then the average of \(\mu_i\) for \(d=C\ln n\) indices is concentrated around 0, and even stronger than not having an \(\ep\)-net, the larged \(d\) of them has to be on the order of \(\rc{\sqrt{d}}\), and can’t be close to 1.
Consider matchings \((x,x+y)\) where \(y\) ranges over the whole group. For \(q\)-query, consider \((x,x+y,\ldots, x+(q-1)y)\).
Is this reasonable? In the MVC construction, we query \((h,hg,\ldots, hg^{(p-2)})\) (i.e., fixing a generator \(g\), this is a line \(g^{w+tv}\)). So the \(p-1\)-query MVC is an example of such a construction for \(q=p-1\).  (But it can’t because doesn’t MVC achieve \(2^{n^{o(1)}}\)
Theorem (Approximate Caratheodory): For \(2\le p<\iy\), given \((x_i)_{i=1}^m\in \R^d\), \(\ep>0\), \(\ga = \max_{i\in[n]}\ve{x_i}_p\), for every \(\mu\in \conv\{x_1,\ldots, x_n\}\) there exists \(i_1,\ldots, i_s,s\le \fc{4p\ga^2}{\ep^2}\) such that \[\ve{\mu-\rc{m}\sum_{i\in S} x_i}_p\le \ep.\]
For 2-query LDC, let \(M_y\) be a group matching, \(\set{(x,x+y)}{y\in G}\), \(\La_{M_y}(f,g) = f*g\).6 Now \(f*g\in \conv\{\chi_a\}\) so Theorem gives that it is \(\ep\)-approximated in \(L_2\) by \(O\prc{\ep^2}\) characters. The \(\ep\)-net is of size \(O\pf{\log n}{\ep^2}\), which gives an exponential bound.
3-query LCC’s:
This doesn’t work for 3-query LDC’s. (It can’t because of MVC’s.) The decoding functions are no longer given by all \(y\in G\), but only \(y\in S\sub G\) where \(|S|=k\). The \(L_1\) norm (normalized) blows up by \(\fc nk\). We have to take \(\ep\leftarrow \ep \fc{k}{n}\), which can make \(c(\ep,d)\) a LOT larger.
Question: Generalize this to
(Use the \(q\)-norm for \(q\)-linear forms because scaling is good?)
Theorem 3.3: For all \(\ep>0\) there exists \(\al,\be\in(0,1]\), \(C:\{-1,1\}^k\to \{-1,1\}^n\) (where \(k=\al \ka(\ep)\), \(n=q|G|\)), \(M_i\) matchings of size \(\fc nq\), such that for all \(x\in \{-1,1\}^k\), \[\EE_{i\in [k],(j_1,\ldots,j_q)\in M_i}[C(x)_{j_1}\cdots C(x)_{j_q}=x_i] \ge\be,\] i.e.,there is a average case LDC with \((r,\fc{\be}2, q)\).7
Proof: Let \(K=\ka(\ep)\) and \(D=(d_1,\ldots, d_K)\sub G\) be a random multiset. Let \[A_i=\rc{K} \La_{d_i} - \rc{K|G|}\La_G.\] Then \[\begin{align} \ep&\le \EE_D\ba{\ve{\rc K\La_D-\rc{|G|}\La_G}}\\ &=\EE_{\mathcal A} \ba{\ve{\sumo ik \pa{A_i-\EE_{\mathcal A'}A_i'}}}\\ &\le \EE_{\mathcal A, \mathcal A'}\ba{\ve{ \sumo ik (A_i-A_i')}} & \text{Jensen}\\ &=\EE_{x_i}\EE_{\mathcal A,\mathcal A'} \ba{\ve{\sumo ik x_i(A_i-A_i')}}& \text{symmetrization}\\ &\le 2 \EE_{x_i,\mathcal A} \ba{\ve{\sumo ik x_iA_i}} &\text{Jensen}\\ &\le \fc 2K \EE_{D,D',x_i} \ba{\ve{\sumo ik \La_{d_i} - \La_{d_i'}}}&\text{symmetrization}\\ &\le \fc 4K \EE_{D,x_i} \ve{\sumo ik x_i\La_{d_i}}& \text{Jensen}\\ \implies \exists D^*, \quad \rc{K}\ve{\sumo ik x_i \La_{d_i^*}}&\ge \fc \ep4. \end{align}\] By Elton’s theorem there exists \(k\ge \fc{cK\ep^2}{16}\), \(E\subeq D^*\) of size \(k\), for all \(x\in \{-1,1\}^E\), \[\rc{k}\ve{\sum_{d\in E} \sum x_d \La_{d}}\ge \fc{c\ep}{4}.\] For each \(x\) there exists \(f^x\), \(\ve{f^x}=1\) with \[\rc k \ve{\sum_{d\in E} x_d \La_d(f_1^x,\ldots, f_q^x)} \ge \fc{c\ep}4.\] We define the LDC by \[\begin{align} C:\{-1,1\}^E &\to (\R^q)^G\\ C(x) &=(f_1^x,\ldots, f_q^x). \end{align}\] Then \(\La\) exactly gives the correlation of the decoded bit: \[\begin{align} \La_d((f_i^x)_i) &= \sum_{g\in G}\prod_i f_i^x(g+(i-1)d)\\ &=\sum_{(j_i)\in M_d} \prod_i C(x)_{j_i}. \end{align}\]Defining \(C'(x)=\fc{C(x)}e\) so that \(\ve{C'(x)}\le \fc{q^{\rc q}}e\le 1\), we get \[ \rc k \sum_{d\in E} \sum_{(j_i)\in M_d} x_d C'(x)_{j_1}\cdots C'(x)_{j_q}\ge \fc{c\ep}{4e^q}, \] the theorem with \(\al=\fc{c\ep^2}{16}\) and \(\be = \fc{c\ep}{4e^q}\). \(\square\)
Note there is a quadratic loss in going from average-case LDC to LDC (using Chernoff).
Smooth decoding: For \(C:\{\pm 1\}^k\to (B^n)^N\) a \((q,\de,\ep)\)-LDC, for each \(i\in [k]\) there exists a probability distribution \(\mu_i\) over \([N]^q\) and functions \(f_S^i,S\in [N]^q\),
Consider a partition of the complete bipartite graph into matchings. What is the worst partition, in the sense that you have to take the union of many (\(\Om(\ln n)\)) matchings before you get an expander in the sense of the Expander Mixing Lemma?
Now consider if the bipartite graph represents a Cayley graph (\(x\) on the left is connected to \(gx\) on the right). “Abelian groups are the worst expanders.”
If you need \(\ge d\) matchings, you get a LDC from \(d\) to \(n\).
Consider tripartite hypergraphs, with \(n^3\) matchings partitioned into \(n^2\). Is the worst partition take \((\ln n)^2\)?
Is this true for just linear codes or any codes?↩
Over other fields, the decoding functions are \(\prod \ze_p^{k_iy_i}\) where \(y_i\in \Z/p\).↩
We can assume exactly \(q\) queries because we can add a few bits that are always 1. What about if we want to negate? Will this ever be the case? In any case we can cover this by adding \(\pm\).↩
Why do these have to be matchings? The fact they are matchings means it’s an LDC with parameters \(\de n q\) for error \(\de q\).↩
This doesn’t make much of a difference for the \(\ep\)-net argument? So for simplicity we just assume \(\{-1,1\}^k\sub \im C\)?↩
(Do we just need \(f*f\)?)↩
Here by \((q,\ep,\de)\)-average case LDC, the parameter \(\de\) means each entry is queried with probability \(\le \fc{\de}{n}\). In my definition of LDC, it’s a \((r,\fc{\be}2-\de q, \de)\)-LDC.↩

Object Capabilities (ObCap) - June 26, 2018
The capability paradigm is about access control. When a system, such as an OS or a website, is presented with a request for a service it provides, it needs to decide if it should actually do what the requestor is asking for.

Networking:
We use sockets for networking.
All the data are sent or recieved as byte arrays (packets) via TCP.
Each client is managed asynchronously by a different server task.
We follow the [client request -> server verify -> broadcast] logic.
Packet encryption:
To minimize packet manipulation via exploits the packet information is encrypted.
A simple implementation is already shared on how to encrypt packet data.
Tho it can be improved I will not extend much on this.
An open source security system is not that much of a security measure.
No UDP support:
There are many controversial conversations on the internet about this.
Most commercial MMORPGs go with this option, so it will do fine for this project.
Packet management:
On both server and client there is a packet manager class.
First it reads the packet byte size and secondly it decrypts the data.
After that it reads the packet id and calls the equilavent recievable implementation with that data.
We use two bytes for both packet size value and packet ids. This ensures we can use up to 32767 of packet data and individual ids.
World regions:
The world area is separated in a 2d region grid.
This vastly limits the information broadcasted to nearby players and makes possible the simultaneous coexistence of hundreds if not thousands of players.
The regions are predefined at WorldManager class by calculating the World.ini configurations and a fixed visibility range.

If you’re having IVF there are a number of different options you might like to consider and discuss with your doctor.
This option may be suitable for men with fertility problems, such as those who produce less sperm, don’t ejaculate or whose sperm is of an unusual shape or movement.
This type of treatment involves no fertility drugs so it may be suitable for women who are unable to take them (due to health reasons for example) or who choose not to.
This type of treatment involves taking fewer fertility drugs than normal, so may be suitable for women who are particularly at risk from having a bad reaction to fertility drugs. Talk to your doctor about whether this applies to you.
This is suitable for younger women with a good chance of getting pregnant through IVF and for women who have produced good quality embryos in a previous cycle, which didn’t implant in the womb.
This may be suitable for older women undergoing IVF however the lack of evidence means it is not currently a recommended treatment.
The main risks from IVF treatment are multiple pregnancies (having twins, triplets or more); having a bad reaction to fertility drugs and having an ectopic pregnancy (where the baby develops outside of the womb). Some of these can be fatal to you, the baby or both so make sure you understand all the risks and when to seek medical help.

TABLE OF CONTENT
This is a long title. Well, the post is going to be long as well.
I want to show how you can set up the CI pipeline using free services and tools.
As an example I’m going to use my pet project: AsyncSuffix plugin for ReSharper. The reason is that the way you pack and publish R# extensions is slightly different from the regular NuGet package. I actually faced some limitations of NuGet.exe and AppVeyor.
GitHub #
Git and GitHub both are kind of industry standard for open source software development nowadays.
I’m using slightly modified version of git flow for my project. I have two mandatory branches master
and develop
.
Master
branch contains released code marked with tags. Develop
branch is for stable pre-release code.
These two branches are configured as protected, so code can never be merged unless CI server reports the successful build. This allows me to publish stable and pre release packages automatically.
The development is taking place in feature branches. The build triggered from the feature branch will create an alpha package and publish it to separate NuGet feed provided by AppVeyor.
GitVersion #
I like the approach suggested by GitVersion. You can define package version based on your branching model.
The basic idea is simple:
- The build triggered by commit to Feature branch produces alpha package, beta packages come from develop branch, release candidates come from master.
- The tag produces stable version.
If you want to get more backgrounds I recommend you a nice couple of posts written by my colleague.
AppVeyor #
I’m using AppVeyor as a CI server.
AppVeyor is a free cloud build server which is easy to integrate with your GitHub repository. Creating the account is simple, you can log in using your GitHub and you’re done.
There are two ways to configure build for the project.
- Using UI
- By placing AppVeyor.yml file to the root of the repository.
First option is good for testing, but committing configuration file to the repository gives you ability to track versions.
The goal #
As I already mentioned, I work in a feature branch and I want to make sure that build is not broken. That means that build server constantly compiles and packs code. However code in a feature branch is most likely unstable and it’s better not to publish it to the official feed.
On the other hand when the feature is complete, tested, and merged to develop
branch I’m more than happy to publish prerelease package.
I’m dogfooding anyway.
External pull requests are different story. The build process must be triggered (how else can I be sure that it’s safe to accept it?). But I don’t want to have any packages created.
Let’s summarise it:
- Build process is triggered by any commit, merge or tag action
- Build process depends on the branch name
Configuration #
First of all we need to agree on the branch naming. Typically it depends on the branching model you use. For GitFlow I’m using the following naming convention:
master
anddevelop
- for stable codefeature/*
- for unfinished features
My AppVeyor.yml
will look like:
Unfortunately there is no way to have common sections in the config file (well, at least at the moment), so we have no other option but having very similar configurations. However AppVeyor evolves very quickly and we can expect some improvements.
Once we have templates defined we can start with actual build steps.
Install GitVersion from Chocolatey
install:
- choco install gitversion.portable -y
Define environment variables (different for each branch configuration)
environment:
resharper_nuget_api_key:
secure: RjiHK3Oxp74LUrI1/vmc2S36zOSRLxFM1Eq0Qn4hixWiou11jFqUbW2ukMNXrazP
Important note: the api key is encrypted and can be published to the public repository.
Restore NuGet packages and set the build version.
before_build:
- ps: nuget restore
- ps: gitversion /l console /output buildserver /updateassemblyinfo /b (get-item env:APPVEYOR_REPO_BRANCH).Value
The build itself:
build:
project: AsyncSuffix.sln
Now it’s time to create NuGet package. AppVeyor has a feature to create packages automatically:
Doesn’t work for me though. At the moment it ignores the content of .nuspec
file,
and performs nuget pack
command on the csproj
file.
That’s why I have to define an after_build
step:
after_build:
- ps: nuget pack AsyncSuffix/AsyncSuffix.nuspec -Version (get-item env:GitVersion_InformationalVersion).Value
I have to specify the version, because the nuget pack
command reads package version from assembly annotations.
Unfortunately I have this annotation:
As you can guess RegisterConfigurableSeverityAnnotation
is declared in one of R# SDK’s assemblies. NuGet fails to load it and falls back to 1.0.0
version.
The final step is different for every branch configuration:
- ps: if(-not $env:APPVEYOR_PULL_REQUEST_NUMBER){
nuget push *.nupkg
-ApiKey (get-item env:resharper_nuget_api_key).Value
-Source https://resharper-plugins.jetbrains.com
}
If APPVEYOR_PULL_REQUEST_NUMBER
environment variable is defined that means that we’re currently performing a synthetic build of merge commit from Pull Request.
The ApiKey
will be transparently decrypted and the package will be published:
P.S. You can definitely do more than publishing packages. You can execute tests, custom build scripts (PowerShell, FAKE) or even deploy your application.


JACK A film review by Michael John Legeros Copyright 1996 Michael John Legeros
(Hollywood) Directed by Francis Ford Coppola Written by James DeMonaco & Gary Nadeau Cast Robin Williams, Diane Lane, Brian Kerwin, Jennifer Lopez, Adam Zolotin, Bill Cosby, Fran Dresche MPAA Rating "PG-13" Running Time 113 minutes Reviewed at General Cinemas at Pleasant Valley, Raleigh, NC (27JUL96)
==
Last seen making trashy vampire movies, Francis Ford Coppola directs this low-powered, light-hearted drama about a boy with the body of an adult. Sound familiar? This time the magic is medical: an infant who is growing at four times the rate of normal. Cut ahead to age ten and Jack Powell, played by Robin Williams, looks like your average forty-year-old adult. (Or, with those hairy arms, your average forty-year-old lumberjack.) Jack is a boy in a suburban bubble. He's tutored at home, his mom doesn't work, and he's given everything he wants, *except* the chance to play with kids his own age. So what happens? Jack Goes to School, where he experiences a bunch of new things, from alienation to acceptance to, finally, awareness about himself and his condition.
Though ultimately unsuccessful as a message movie-- the moral of the story is... people get old? Well, duh-- JACK is endearing enough. And entirely recommendable. Given plenty of room to act his age, Robin Williams delivers a performance that is warm, funny, and far from ingratiating. No Oscar baiting here; not in a movie featuring such frivolity as fart lighting. (Suggested story idea for CHAIN REACTION 2: Keanu Reeves spends two hours fleeing his own flatulence. Sorry.) The pokey pacing, however, makes for a bit of a long sit. As does the occasionally gushing sentiment and the ever-dawning realization that the story isn't going anywhere in particular. Except, perhaps, as fodder for the next Mel Brooks spoof. (Suggested title: LARGE.) With strong supporting work from Bill Cosby, Fran Drescher, and Michael McKean.

HTML, CSS and JavaScript are 3 main languages of Web Front-end Development. In this article, I will cover the basics of CSS. So if you have no idea about CSS, or don’t know how to use it, this article is for you :)
We will have a look at what CSS is, how to write CSS rules and how to add them to HTML. As a pre-requisite, if you don’t know anything about Web Development, I recommend you to understand HTML first.
What is CSS?
CSS (Cascading Style Sheets) is a language for styling the webpage. We can change the appearance and the layout of the webpage by using CSS. We can also define how a website’s view changes in different screens like desktops, tablets, and mobile devices.
CSS is not a programming language, like C++ or JavaScript. However, CSS is not as easy as it seems. If you try to use it without understanding, you will have difficulties in web development. Therefore, learning CSS is as important as learning a programming language.
Let’s continue with an example to reveal the effect of CSS on a website. Below is an example of how Stuff.co.nz looks like without CSS or JavaScript.
1. External CSS File:
Keeping CSS code in a separate file is best practice. In real programming world, we need to keep HTML, CSS and JavaScript code in separate files and later import them where necessary.
We can create a separate CSS file with an extension of .css and include it to HTML. For example, we can create a CSS file like this one: index.css
Inside index.css
, we can write our CSS code:
Then we can import index.css to HTML with a link tag like below:
Hello World
So now the HTML file has the CSS code and the changes will apply to the elements.
2. Internal CSS with style tag:
Another way where you can write CSS code is inside a style tag in HTML. This will keep the CSS code directly inside the HTML file, rather than in a separate file.
Hello World
3. Inline style:
The third way is to write CSS rules directly inside an HTML element, with the style attribute. In this method, we define the CSS rules directly inside the tag and don’t need to create a class for it.
This approach is not an example of clean code and it’s not recommended to use.
Conclusion
CSS is an essential part of Web Development. In this article, I tried to explain the very basic usage and syntax of CSS. If you have any questions, don’t hesitate to ask them below in the comment section.
There are many other rules and features to explore in the world of CSS. I will be covering them in my following articles.

I am seeking opportunities to advance my career as a software engineer in either app development,
web development, or other entry level positions in software.

Greedy Algorithm can help us skip some of the conditions. It is base on a fact that the area between two columns are determined by the shorter one.
Let’s say we have pointer l
and r
at the begin
and end of a distance, and the area is area(l, r)
, how should
we narrow down the distance?
If height[l] < height[r]
, we know that the height of the
area will never be greater than height[l]
if we keep
l
. Now if we get rid of r
, the area can only get
smaller since the distance is shorter, and the height is at most
height[l]
.
Here we conclude rule NO.1: Get rid of the smaller one.
What if height[l] == height[r]
? It is safe to get rid of
both. We do not need any of them to constrain the max height of the rest
points.
/**
* @param {number[]} height
* @return {number}
*/
var maxArea = function (height) {
let max = 0
for (let l = 0, r = height.length - 1; l < r; l++, r--) {
max = Math.max(max, (r - l) * Math.min(height[l], height[r]))
if (height[l] < height[r]) {
r++
} else {
l--
}
}
return max
};

FDM is an IT services provider with a large number of clients on a global scale.
While working with FDM I was placed on two client sites in two different roles:
Implemented a “build once” pipeline for 9 major components using gradle and teamcity. During this process we migrated from using maven as a build tool to using gradle to free ourselves from the maven build cycle, and configured our teamcity pipeline to pass built artifacts along to avoid rebuilding in the various test phases.
Developed a build radiator using Groovy, Ratpack, AngularJS and Javascript to display current build statuses, as well as a score board of which Developers had broken builds or commited on broken builds without fixing them.
Performed a migration of data from 10g to 11g Oracle databases in two test environments before decommissioning the 10g databases.
Coordinated an upgrade of 3 testing environments from using an MQ6 to an MQ7 server, making changes to our own environment and liasing with other teams to make changes to their connected applications.
Developed scripts using Groovy, gradle, and teamcity, rally, github and svn APIs to automate processes between the tools such as creating changesets in Rally for each commit, creating teamcity projects and scm roots for new repos, reporting on rally stories included in the next release and more.
Created a server that adds dynamic images to pull requests that report on the status of the teamcity pipeline for that branch as well as master, to enable devs to see easily if it's ok to merge.
Developed a number of test packs for front-end applications and APIs using java, groovy and selenium.
Implemented a solution using Jenkins and maven to build and run test packs daily against production to monitor status, as well as against newly deployed code in the various pre-prod environments as part of the continuous delivery build pipeline.
Provided testing support for changes in third party applications that could possibly affect our own, as well as an upgrade from Oracle 10 to Oracle 11 and a migration of the production data centre.


Review Completeness
Review that all parts of the document exists and that each part actually contains what it should
- Test Strategy
- Does the strategy describe stakeholders and their testing goals?
- Does the strategy describe the available resources?
- Does the strategy describe how the stakeholders testing goals are to be fulfilled by the plan?
- Test Plan - Should describe and outline the current iteration's test effort(Who does what when).
- Does the test-plan describe what requirements that should be tested?
- Does the test-plan describe what requirements that should NOT be tested?
- Does the test-plan describe how testing should be done? at what test-level?
- Does the test-plan describe who should do different activities? (responsibilities)
- Manual Test Cases
- Are the manual test-cases traceable to which requirement that is tested?
- Do each manual test-case describe, input and expected output? (when relevant)
- Test Report
- Does the test-plan show what has been tested and not tested?
- Does the test-report show which tests that fail or succeed?
- Is there testing the other group should have done?
