The Corporate iCloud
June 10, 2011 · 5 minute read · CommentsRead OnApple’s announcements at this year’s WWDC keynote will have far reaching effects. Much has already been written about the impacts to you and me as consumers of Apple products. But let’s stop and think for a moment about how this will affect our perceptions about technology, and how that will translate into the corporate IT space.


As a solution to Smyth and Cortier’s attack to reveal votes, we propose an overkill measure of hiding the encrypted ballots and disabling the ballot verification feature. While disabling the attack, this is an egregious compromise to Helios’ key open-audit verification feature. However, in the process of experimenting with the degree of overkill, we found interesting implications in the confidentiality and integrity of Helios. This led us to develop a new customizability feature to Helios.
To completely remove Helios’ open-audit feature is not only difficult, as it requires large changes to the code, but also unnecessary for our demonstration purposes. To disable the Smyth and Cortier attack, it suffices to hide the encrypted ballots from the public.
A voter's encrypted ballot is shown in the vote’s cast-vote page. An example is shown in the image below. When the ‘details’ link is clicked, the encrypted ballot is revealed.
The cast-vote page can be accessed in two ways. One is in the Voters and Ballot Tracking Center page (in the image below), which can be accessed from the election. The Ballot Tracking Center (BTC) contains a table of all voters’ name or alias, their Smart Ballot Tracker, which is a “fingerprint” of the encrypted ballot, and their encrypted ballot, which can be accessed through the ‘view’ link. The other way to access the cast-vote page is through a link sent to the voter’s emails after a vote is casted.
To completely hide encrypted ballots, we can simply disable the ‘details’ link in the cast-vote page. This can be done by commenting out line 16 in helios/templates/castvote.html. We do not need to make changes to the BTC, although the Smart Ballot Trackers are now redundant. This is our baseline defense to the attack.
We further derived a few extension defenses. Recall the two different ways to access the cast-vote page, one through the BTC and one through voters’ emails. The BTC is available to the public while voters’ emails are private. This naturally leads to a convenient separation between the public and voters’ themselves. That is, we can disable the public’s access to the cast-voter page while maintaining the voters’ access. The result of this is that only voters themselves can access their own encrypted ballot. In turn, Helios’ verifiability feature is not completely removed, but restricted to voters only. This is our first extension defense. It negates the Smyth and Cortier attack as encrypted ballots can not be accessed without coercing a target voter or hacking their email.
The implementation is to remove the link to the cast-vote page in the BTC along with the Smart Ballot Tracker fingerprint, since the fingerprint can be used to derive the cast-vote page html address. This can be done by editing line 154 in helios/templates/voters_list.html. An implementation is shown in fig. 3
The second extension defense is to hide encrypted ballots but only when the election is open. This defense also preserves Helios’ open-audit feature to some extent: anyone can verify any votes, but only after the election is closed. The practicality of this defense is less apparent compared to the previous extension defense. While the Smyth and Cortier attack is impossible during the election, verifiability of the election after it closes may be less helpful to the integrity of the election. Implementation of this defense can be done by using the election.voting_has_stoppped boolean in Helios’ django model.
We quickly found some patterns. The baseline method to completely hide encrypted ballots was the “most overkill” measure, while the two extension defenses preserved encrypted ballots in different ways. The second extension defense was straightforward in that it added a dimension of time to the defense. But the first extension defense of restricting verifiability to voters was far more interesting. In fact, it ties directly to two properties of electronic voting systems introduced by Smyth and Cortier:
Individual verifiability: A voter can check that her own ballot is published on the election’s bulletin board.
Universal verifiability: Anyone can check that all the votes in the election outcome correspond to ballots published on the election’s bulletin board.
Helios’ open-audit feature corresponds exactly to universal verifiability, although in their research they used the term “true verifiability”. Our first extension defense happens to satisfy the criteria of individual verifiability. Along with the baseline defense, Helios’ open-audit feature and our measure of restricting verifiability to voters form a scale of verifiability where the varying factor is “who can audit which votes”. A visualization is shown below.
However, the varying factors on this scale are not just verifiability. Our baseline defense disables the verifiability feature, but also completely hides encrypted ballots, in turn guaranteeing full ballot secrecy. So, in the opposing direction of verifiability is ballot secrecy. Indeed, the two are in conflict, which is even acknowledged by the Helios contributors : “In cryptographic voting protocols, there is an inevitable compromise: unconditional integrity, or unconditional privacy” (Adida, 2008, p.336). In this case integrity corresponds to verifiability and privacy to ballot secrecy. Helios’ approach is to guarantee unconditional integrity by ensuring full transparency of the election and tallying process, since anyone can verify any vote. On the other hand, our baseline defense, by not revealing any encrypted ballots, would provide unconditional privacy, or--using the terms of our threat model--confidentiality. Thus, we can construct an updated scale, as shown below.
Currently there are only three discrete values on our scale, but more options are possible. For example, between universal verifiability and individual verifiability, there may be a midpoint feature of allowing voters to verify any votes.
Since we already have all three values on our scale readily implemented, we went a step further to combine them to a customizability feature such that when creating an election, the administrator can choose a point on the scale. That is, one can decide whether their election has universal verifiability, individual verifiability, or no verifiability; our scale of verifiability and ballot secrecy is thus one parameter of the customizability feature. We added another parameter of before and after the election closes, taken from our second extension defense. Thus, our customizability feature is shown in (1a) with parameters underlined. As a comparison, (1b) summarizes Helios’ open-audit feature.
(1a)
(1b) Anyone can verify any voters’ votes at any time.
Since the baseline and extension defenses were already implemented, the remaining work was to convert the defenses into parameters in a Helios’ election. To do this we added two fields to Helios’ Django form and Django model; details about the modifications are on our github. The updated create-election form is shown below.
It is worth noting that we initially considered two versions of the customizability feature. The first is the one described before, granting users full customizability of the parameters. The other one being to offer to users only a few combinations of the parameters. The reasoning is that some combinations are less meaningful than others, such as allowing anyone to audit before the election closes but allowing no one to audit after the election closes. We ultimately decided on the full customizability version for two reasons. The first being our trust to the user: people that create elections are likely to be familiar with concepts like verifiability and ballot secrecy, so we trust that they will not make meaningless or silly decisions. The second is that, even if users are not familiar with election security, full customizability exposes the user to potentially too much information and forces them to modify all the parameters; then, the user is more likely to learn the advantages and disadvantages of each option and familiarize themselves with integrity and privacy.
Our initial planning of the customizability feature had an additional parameter that differentiated between admin and non-admin permissions. However, we encountered problems when implementing this parameter. The Helios Django parameter field that checks whether the user is an administrator is admin_p. Admin_p functions correctly in templates/voters_list.html but not in templates/castvote.html. We do not know the reason behind this so we have not been able to implement this feature, although it still appears in the create-election form as disabled features.
A conceptual point of future work is expanding the scale of verifiability and ballot secrecy. Currently we have three points on the scale, universal verifiability, individual verifiability, and no verifiability. Additional points can easily be conceptualized and implemented. For example, the administrator can restrict audit permission to a specific group of people. This might be useful in school or corporate elections.
For any voting system to be considered fair and functional, it must be usable by every member of the voting body. In many elections, this could mean any individual of a responsible age, including those who are elderly, disabled, uneducated or unfamiliar with the technology being employed. In most cases, voters should be able to perform this function without requiring training or prolonged instruction, so systems should be self-explanatory and easy to understand.
While EVMs have the potential for high levels of accessibility, they can also be uniquely difficult if not well implemented. A 2003 study conducted in Maryland examined accessibility of one of the state’s EVMs (Bederson et al, 2003). It found that around 1 in 10 voters had significant concerns when using the system, ranging from readability issues to difficulty navigating their electronic ballot.
The 1.0 version of Helios performed even more poorly in this regard, with some studies showing that up to half of voters using the software were unable to complete the voting process (Karayumak et al., 2011). Issues such as overly-technical language and misleading error messages were main factors. While Helios 2.0 addresses many of the faults of its predecessor, it still demonstrates room for improvement.
To identify key issues with the Helios 2.0 software, we conducted an informal survey of 16 Carleton students. We created an election for testing purposes and sent a link simultaneously to all participants. The only instructions provided were network requirements (some students would need to use a VPN to connect), an encouragement to find and use the audit feature, an encouragement to view the bulletin board, and an invitation to send any feedback to the admin email account. We reached out to all students who didn’t initially send feedback and ultimately received all 16 responses.
We combined this research with two other pieces of research. The first was a cognitive walkthrough of Helios’ voting procedure based on previous studies (Karayumak), and the second was a study of a similar EVM being tested for the same kind of usability concerns (Bederson). By synthesizing the finding of these two sources with our own work, we identified a number of key issues to address.
While many other issues were identified, these were the ones that presented the most serious problems without requiring major overhauls.
The first of these was to update the audit feature to make it easier to use and understand. Previously, Helios displayed the option to audit off to the side as an ‘optional’ feature, and only provided a (brief) explanation after the link is clicked. We moved the audit button down to appear alongside “Submit this Vote” and provided explanatory text for each choice, which further clarifies that picking one option exempts the user from using the other, and specifies that after auditing, a new ballot will need to be cast. Additionally, the word “verify” was substituted for “audit” where applicable, both here and on the audit page.
Logging in is also a difficult process for some users. Helios divides its content pane into both a header and footer, with the login button and indicator exclusively found in the footer. We updated this by moving the login button and indicator into the header, in the upper right corner to correspond with current web standards. The message tells the user they need to either log in now using the button in the top right, or log when prompted during ballot submission.
To clarify when and how logging in must be performed, a message now displays above the “Vote in this election” button if the user it not yet logged in.
The arrangement and language used in the ballot-completion step was updated to be more clear and consistent, and a message was included informing voters how to change their selections. The "Next" button (shown here in red) now always appears in the same spot, the option to "Proceed" is now "Encrypt Ballot for Submission" and only is visible on the last question.
While these fixes address some of the major issues, there are a number that our team was aware of but could not address to due time or technical limitations. Among these include:
Further work on this project should seek to make these changes and further examine how these changes have affected the usability of the software.


People use a variety of workflows when merging plugins. Below is a breakdown of these workflows including their pros and cons. These workflows didn't really have names, but I've assigned descriptive names to them here for the purpose of this comparison.
Disable Plugins Workflow
This is the default workflow in zMerge. This workflow involves disabling plugins in the plugins.txt
file while leaving the merged mods installed. Disabled plugins do not count towards the 255 plugin limit.
Pros:
- Allows you to rebuild merges in zMerge at any time without any extra steps.
- Can be used with any mod manager.
- zMerge has an integration which disables plugins after they are merged. This integration is enabled by default.
Cons:
- Clutters your load order a little bit with disabled plugins.
Hide Plugins Workflow
This workflow was mostly used by users of Mod Organizer. It involves marking merged plugins as hidden (which appends the .mohidden prefix to them) so they are no longer active in your load order. An extension for MO was created to support this workflow with Merge Plugins Standalone.
Pros:
- Keeps your load order clean and uncluttered.
Cons:
- Requires a lot of manual steps when rebuilding merges.
- The MO extension doesn't work with zMerge.
- Can only be used by Mod Organizer users.
Merge Everything Workflow
Any workflow which involves copying general assets would fall under this designation.
Pros:
- Creates a single mod package which can be distributed.
Cons:
- Merges take more time.
- Rebuilding merges requires re-enabling the mods that were merged unless you use a separate MO profile.
- Merged mods take up twice as much hard drive space. This is a larger problem if you store your mods on an SSD with limited storage capacity.
- Cannot be used with mod managers that do not isolate mod data files.

Rejections
In the chapter about constructing Routes the ~ operator was introduced, which connects two routes in a way that allows a second route to get a go at a request if the first route "rejected" it. The concept of "rejections" is used by Akka HTTP for maintaining a more functional overall architecture and in order to be able to properly handle all kinds of error scenarios.
When a filtering directive, like the get directive, cannot let the request pass through to its inner route because the filter condition is not satisfied (e.g. because the incoming request is not a GET request) the directive doesn't immediately complete the request with an error response. Doing so would make it impossible for other routes chained in after the failing filter to get a chance to handle the request. Rather, failing filters "reject" the request in the same way as by explicitly calling requestContext.reject(...).
After having been rejected by a route the request will continue to flow through the routing structure and possibly find another route that can complete it. If there are more rejections all of them will be picked up and collected.
If the request cannot be completed by (a branch of) the route structure an enclosing handleRejections directive can be used to convert a set of rejections into an HttpResponse (which, in most cases, will be an error response). Route.seal internally wraps its argument route with the handleRejections directive in order to "catch" and handle any rejection.
Predefined Rejections
A rejection encapsulates a specific reason why a route was not able to handle a request. It is modeled as an object of type Rejection. Akka HTTP comes with a set of predefined rejections, which are used by the many predefined directives.
Rejections are gathered up over the course of a Route evaluation and finally converted to HttpResponse replies by the handleRejections directive if there was no way for the request to be completed.
The RejectionHandler
The handleRejections directive delegates the actual job of converting a list of rejections to its argument, a RejectionHandler, which is defined like this:
trait RejectionHandler extends (immutable.Seq[Rejection] ⇒ Option[Route])
Since a RejectionHandler returns an Option[Route] it can choose whether it would like to handle the current set of rejections or not. If it returns None the rejections will simply continue to flow through the route structure.
The default RejectionHandler applied by the top-level glue code that turns a Route into a Flow or async handler function for the low-level API (via Route.handlerFlow or Route.asyncHandler) will handle all rejections that reach it.
Rejection Cancellation
As you can see from its definition above the RejectionHandler doesn't handle single rejections but a whole list of them. This is because some route structure produce several "reasons" why a request could not be handled.
Take this route structure for example:
import akka.http.scaladsl.coding.Gzip
val route =
path("order") {
get {
complete("Received GET")
} ~
post {
decodeRequestWith(Gzip) {
complete("Received compressed POST")
}
}
}
For uncompressed POST requests this route structure would initially yield two rejections:
- a MethodRejection produced by the get directive (which rejected because the request is not a GET request)
- an UnsupportedRequestEncodingRejection produced by the decodeRequestWith directive (which only accepts gzip-compressed requests here)
In reality the route even generates one more rejection, a TransformationRejection produced by the post directive. It "cancels" all other potentially existing MethodRejections, since they are invalid after the post directive allowed the request to pass (after all, the route structure can deal with POST requests). These types of rejection cancellations are resolved before a RejectionHandler sees the rejection list. So, for the example above the RejectionHandler will be presented with only a single-element rejection list, containing nothing but the UnsupportedRequestEncodingRejection.
Empty Rejections
Since rejections are passed around in a list (or rather immutable Seq) you might ask yourself what the semantics of an empty rejection list are. In fact, empty rejection lists have well defined semantics. They signal that a request was not handled because the respective resource could not be found. Akka HTTP reserves the special status of "empty rejection" to this most common failure a service is likely to produce.
So, for example, if the path directive rejects a request it does so with an empty rejection list. The host directive behaves in the same way.
Customizing Rejection Handling
If you'd like to customize the way certain rejections are handled you'll have to write a custom RejectionHandler. Here is an example:
import akka.actor.ActorSystem
import akka.stream.ActorMaterializer
import akka.http.scaladsl.Http
import akka.http.scaladsl.model._
import akka.http.scaladsl.server._
import StatusCodes._
import Directives._
implicit def myRejectionHandler =
RejectionHandler.newBuilder()
.handle { case MissingCookieRejection(cookieName) =>
complete(HttpResponse(BadRequest, entity = "No cookies, no service!!!"))
}
.handle { case AuthorizationFailedRejection =>
complete((Forbidden, "You're out of your depth!"))
}
.handle { case ValidationRejection(msg, _) =>
complete((InternalServerError, "That wasn't valid! " + msg))
}
.handleAll[MethodRejection] { methodRejections =>
val names = methodRejections.map(_.supported.name)
complete((MethodNotAllowed, s"Can't do that! Supported: ${names mkString " or "}!"))
}
.handleNotFound { complete((NotFound, "Not here!")) }
.result()
object MyApp extends App {
implicit val system = ActorSystem()
implicit val materializer = ActorMaterializer()
val route: Route =
// ... some route structure
Http().bindAndHandle(route, "localhost", 8080)
}
The easiest way to construct a RejectionHandler is via the RejectionHandler.Builder that Akka HTTP provides. After having created a new Builder instance with RejectionHandler.newBuilder() you can attach handling logic for certain types of rejections through three helper methods:
- handle
- Handles certain rejections with the given partial function. The partial function simply produces a Route which is run when the rejection is "caught". This makes the full power of the Routing DSL available for defining rejection handlers and even allows for recursing back into the main route structure if required.
- handleAll[T <: Rejection]
- Handles all rejections of a certain type at the same time. This is useful for cases where your need access to more than the first rejection of a certain type, e.g. for producing the error message to an unsupported request method.
- handleNotFound
- As described above "Resource Not Found" is special as it is represented with an empty rejection set. The handleNotFound helper let's you specify the "recovery route" for this case.
Even though you could handle several different rejection types in a single partial function supplied to handle it is recommended to split these up into distinct handle attachments instead. This way the priority between rejections is properly defined via the order of your handle clauses rather than the (sometimes hard to predict or control) order of rejections in the rejection set.
Once you have defined your custom RejectionHandler you have two options for "activating" it:
- Bring it into implicit scope at the top-level.
- Supply it as argument to the handleRejections directive.
In the first case your handler will be "sealed" (which means that it will receive the default handler as a fallback for all cases your handler doesn't handle itself) and used for all rejections that are not handled within the route structure itself.
The second case allows you to restrict the applicability of your handler to certain branches of your route structure.

| SUMMARY: INNER | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
The delivery modes supported by the JMS API are PERSISTENT
and
NON_PERSISTENT
.
A client marks a message as persistent if it feels that the application will have problems if the message is lost in transit. A client marks a message as non-persistent if an occasional lost message is tolerable. Clients use delivery mode to tell a JMS provider how to balance message transport reliability with throughput.
Delivery mode covers only the transport of the message to its
destination. Retention of a message at the destination until
its receipt is acknowledged is not guaranteed by a PERSISTENT
delivery mode. Clients should assume that message retention
policies are set administratively. Message retention policy
governs the reliability of message delivery from destination
to message consumer. For example, if a client's message storage
space is exhausted, some messages may be dropped in accordance with
a site-specific message retention policy.
A message is guaranteed to be delivered once and only once
by a JMS provider if the delivery mode of the message is
PERSISTENT
and if the destination has a sufficient message retention policy.

Summary
This release completes the overhaul of primitive operators in the compiler that was started in 110.86. Most of the changes listed here were part of the 110.86 release, but we include them here since 110.86 was not officially announced.
Details
Installation
While the installer for 110.87 works on macOS 10.14 Mojave, building from source requires some extra steps.
SML/NJ Library
Renamed the function CharBufferPP.openOut
to openBuf
, and added the
TextPP
structure that supports pretty printing to either an output
stream (like TextIOPP
) or a character buffer (like CharBufferPP
).
ASDL
Further improvements to the new implementation of ASDL.
-
The interface to file and memory picklers was unified for the SML view.
-
Added support for S-Expression pickling for the SML view (unpickling has not yet been implemented).
-
Significant editing of the documentation to make it more accurately reflect the implementation.
Compiler
110.86 changes
We have made a number of changes to internal representations and implementations as part of the preparation for supporting 64-bit targets. We summarize these below (see the change log for details).
-
Moved CPS related code out of the FLINT directory and into its own
compiler/CPS
directory tree. -
Split out the utility code from the
CPS
structure into a newCPSUtil
structure. -
Renamed the various CPS primitive constructors so as to be compatible with ASDL (i.e., changed symbolic and lower-case constructor names to upper-case identifiers).
-
Moved the
F_SGN
constructor from thefcmp
datatype to thebranch
datatype (and renamed itFSGN
). -
Many changes to the internal representation of primitive operators.
We have also made improvements to the core 64-bit arithmetic operations.
Culled unused flags from the Control
structure (mostly from Control.CG
).
110.87 changes
In 110.87, we continue the overhaul of the compiler’s handling of primitive
operations by introducing a new, more consistent, naming scheme for the
operations that are exposed by the compiler in the InLine
structure.
In particular, we have abstracted away from the size of the default integer
and word types (both in the names and in the semantics of numeric conversions).
The compiler now inlines the Char.chr
operator.
Interactive System
The implementation of the use
function in the REPL has been rewritten to
fix bugs 193, 217, and 219. The semantics of
use
are as follows:
-
If an invocation of
use
encounters a compilation error (either in the initial file or in a nested invocation ofuse
), then the compiler error message will be printed and the call touse
will immediately return()
. -
If an invocation of
use
raises an exception during execution of the compiled code (either in the initial file or in a nested invocation ofuse
), then the exception will be reported at the top-level. -
Otherwise, if no errors or uncaught exceptions are encountered, then
()
will be returned once the code in the used file has executed.
Note that any change to the global state or environment
that occurs before an error is encountered, will not be rolled
back. Also, wrapping calls to use
in exception handlers or using
callcc
in combination with use
may break it.
Files specified as command-line arguments to the sml command
are treated as if use
was invoked on them. If there is an
error, then the error is reported and the sml command
will terminate with a non-zero exit status (at least on Unix).
Bugs
Here is a list of tracked bugs fixed (or closed) with this release, please see the bug tracker for more details.
193 |
SML/NJ does not print unhandled exceptions in loaded files |
213 |
|
217 |
Unhandled exceptions no longer print anything when inside used file |
219 |
"use" fails silently when a function inside a structure raises an exception |
The following unnumbered bugs were also fixed:
-
The
Word32.toInt
function did not raiseOverflow
when given an argument with its sign bit set in some cases (e.g.,Word32.toInt 0wx8002DE32;
would return187954
).

A note about 64-bit support
Apple is in the process of deprecating 32-bit support in macOS. With macOS 10.14 Mojave, compiling 32-bit applications, such as the SML/NJ runtime system, requires using an older SDK. The SML/NJ installer, however, works without issue on macOS 10.14 Mojave.
We have been working on 64-bit support since 110.82 we expect to have it in place before the release of macOS 10.15.

Through the focused mental engagement that you are able to tap in to thorough understanding the principles of neuroplasticity, you are able to improve both the speed and efficiency in your learning as you will configure your neural networks to much more easily work with whatever related task at hand you are attending to.
In the context of the foundations and the bootcamp, I plan to engage with these principles through both physically and mentally immersing myself in my code in a number of different ways. (i.e. Using breakpoints and analyzing the focused line of code to understand the purposed functionality, physically writing any example code given or found in order to build upon muscle memory etc..)
Practicing through Repetition. Relating newly observed information and contextualizing it in different ways. Consistent reminders that the capacity of knowledge is not limited, and not knowing something doesn't equal not being able to know something. Confusion implies an incomplete connection. A resource that I found useful for neuroplasticity can be found here
Growth mindset is the idea that knowledge is ever expanding through a lifetime. New habits, new information, new abilities, new techniques, new skills can all be learnt and obtained. A fixed mindset implies that the current capacity of knowledge that one has is incapable of being grown. As a developer, having the perspective that you can always learn more, is a very strong mindset to have, as the development world is ever expanding, and the ability to stay engaged and to keep up is an important asset.
This exploration didn't surprise me, as employing this mindset throughout my learning over the years has helped me in a great manner. The evidence of this, for me, is seeing how I learnt prior to this mindset, compared to my learning after.
To put it simply. Through researching and questioning out of the interest of growth, rather than out of perceived confusion or lack of knowledge. A resource that I found very useful for learning about the integration of a growth mindset can be found here
Over the years, through the application of employing a growth mindset, I have learnt and applied methods to address my natural learning and communication barriers that are symptoms of my Asperger's. I will continue to apply this mindset when it comes to my learning and communicating at EDA.
With my long term career goal of being a remote based developer in mind, I intend to grow as comfortable as possible working from home as possible in order to achieve maximum efficiency within that environment.
In order to meet my goal of finetuning my communication style, I intend to practice talking to my fellow students and facilitators, and to seek feedback on my communication abilities when possible. Practicing through repetition.
In relation to coding, both neuroplasticity and a growth mindset will be incredible relevant. Building up muscle memory for the process of typing coding is important, as is gaining outside perspective through asking for help or feedback from team members when you ask them to look at your code. A growth based mindset removes the intimidation of approaching newer technologies and languages within web development, and enables you to increase your portfolio/experiences, leading to more potential job opportunities later down the road.

Added opponent tyre type info when they leave the pits after changed tyre type.
Version <IP_ADDRESS>
- R3E 64Bit support
- Added voice command to tell you (once the data is availalbe) what the relative performance difference is between different tyre types based on the best lap in the session for tyre type - e.g. "Softs are about 0.4 seconds faster than Mediums, Mediums are about 1.2 seconds faster than Hards". The voice command is "Give me tyre pace differences", "What are the tire speeds?" / "Whats the difference between tires?" / "Compare tire compounds" (currently R3E only)
- Added opponent tyre type info when they leave the pits after changed tyre type
Version <IP_ADDRESS>
- More RF2 race end detection fixes
- Added Imola corner mappings for R3E
- fixed race start message being repeated on manual rolling starts
- Some additional checks to prevent mandatory pitstop messages playing during or after you've completed your stop
Version <IP_ADDRESS>
- Compatibility fixes for new Raceroom shared memory layout
- Map to new Raceroom tyre types - you can ask "what tyres is [opponent name] on?", or "what tyres am I on?"
Version <IP_ADDRESS>
- Better sound pack update mechanism - wastes less bandwidth
- Added "minimise to tray" and "start minimised" options. Minimise to tray places a Crew Chief icon in the system-tray when you minimise the app, with a right-click menu contain commonly used functions. The app can be started minimised if desired
- Added a new fuel calculation command ("calculate fuel for [x] [laps / minutes / hours]" / "how much fuel do i need for [x] [laps / minutes / hours]" / "how much fuel for [x] [laps / minutes / hours]") - for example, "how much fuel do I need for twenty minutes?". Assuming the app's had the chance to record your fuel usage over at least one lap (the more the better), it'll estimate how much fuel you'll need for the requested number of laps / time based on your average consumption. IMPORTANT: if you use this to set your fuel load in a timed race you MUST add extra fuel to account for the lap you need to finish after the race timer reaches zero. The app WILL NOT DO THIS FOR YOU - if you put in exactly 20 minutes worth of fuel for a 20 minute race you'll run out on the last lap
- Only allow manual formation lap mode to supress messages in race sessions (fixes missing messages in practice and qual with manual formation lap mode enabled)
- Fixed session end detection in RF2 / AMS / RF1 - the app should also detect when you click 'next session' without clicking 'end session' first
- Fixed some issues in the fuel use tracking logic
Version <IP_ADDRESS>
- Fixed initialisation errors in TTS engine which prevented the app from starting when "Use TTS for missing names" was enabled
- added option to select where the race starts on a manual formation lap - "Manual formation 'go' when leader crosses line". If this is true (the default) the app assumes that the race starts and cars are allowed to overtake as soon as the leader crosses the start line. If it's false, the app assumes that no one is allowed to overtake until they cross the start line
- Added some RF1 session identifier fixes - should correct a few issues caused by the app thinking the race was actually qualifying.
Version <IP_ADDRESS>
- Fix for some settings getting corrupted on system which use a comma as a decimal separator - this causes some spotter and voice recognition issues. If you have already encountered this, please reload the app's default settings
- Added manual formation lap support. This supresses most messages on lap 1 and plays an alternate sequence of start messages - it assumes you're not allow to pass until you cross the start line. This mode can be activated and deactivated with a button press ("Toggle manual formation lap mode") or a voice command (enable with "this is the formation lap" / "formation lap" / "rolling start", disable with "standing start" / "no formation lap").
- Some fuel use calculation fixes
- Spotter fixes
Version <IP_ADDRESS>
- Added optional radio beeps for when the spotter or the Chief interrupt each other. "Insert beep-out between Spotter and Chief" plays the close-channel beep after the chief / spotter has finished, and "Insert beep-in between Spotter and Chief" (the default) plays the open-channel beep before the chief / spotter interrupts. The spotter and chief use different beep sounds here, and these options can be combined if you want 2 beeps (close then open) when interrupting
- Attempt to delete corrupted settings and force the app to restart if they can't be processed
- Don't play fuel consumption estimate if it's 0 litres per lap
Version <IP_ADDRESS>
- RF2 plugin fixes for car damage issues in online races
Version <IP_ADDRESS>
- Fixed spotter logic where it would consider 2 cars along side to be "3 side", even if those cars were one behind the other
- Use oval spotter messages (inside / outside) when on known oval tracks, if the selected spotter has these sounds
- Tweaked spotter enable / disable sound to be a bit more appropriate for non-default spotter voice packs
- Fixed broken sector 3 time deltas in Project Cars
Version <IP_ADDRESS>
- Fixed Assetto Corsa pit window open calculation for sessions with a fixed number of laps
- Fixed a crash bug when starting the app with no sound pack
Version <IP_ADDRESS>
- Added dropdown to main screen to allow a different spotter voice to be selected
- Added Geoffrey Lessel's awesome spotter sounds - these are in the latest sound pack. Select "Geoffrey" from the new 'Spotter voice pack' menu
- Fixed a couple more spotter bugs
- Added button binding to get fuel status (consumption and fuel remaining). The "how's my fuel?" voice command now reports the consumption as well as the remaining fuel
Version <IP_ADDRESS>
- More Scoops-Brand RF2 corner mappings
- Fixed some spotter bugs
- Added searching to Properties screen to make it a little less user-hostile
- Replaced the nasty underscore_property_names with proper names on the Properties screen
Version <IP_ADDRESS>
- Substantial RF2 plugin rewrite
- Attempt to map game data if we detect the PCars2 exe - this does (apparently) work but expect some bugs and issues
- Ported some fixes from the PCars Android app - some free practice session improvements, more aggressive pruning of broken driver data, better (hopefully...) method of identifying player's data so monitoring other drivers shouldn't confuse the app
Version <IP_ADDRESS>
- Overhauled internal sound handling to make the app behave better
- Use game-provided mandatory pitstop data where available (should fix app thinking you've completed your mandatory pitstop when the game thinks otherwise)
- Some more car and track mappings from Scoops
- Added 'three wide you're on the left' and 'three wide you're on the right' to the spotter - optional, disabled by default (spotter_enable_three_wide_left_and_right in the Properties screen)
- Added voice command to get info about the car in front / behind is slower / faster than you - "where should I attack" / "where am I faster" / "where can I attack" or "where should I defend" / "where am I slower" / "where is he faster" / "where will he attack"
- Mapped Watkins Glen for PCars
- A few bug fixes
- Added fuel use per lap response - "what's my fuel usage" / "what's my fuel consumption" / "what's my fuel use"
Version <IP_ADDRESS>
- Faster start up times
- Better CPU usage
- Some internal fixes
- more of Scoop's corner mappings (recordings still to be done)
Version <IP_ADDRESS>
- Fixed some RFactor and RFactor2 issues
- Added a few more track location mappings (thanks again Scoops)
- Disabled 'incident ahead' in R3E while I resolve the false-positives
Version <IP_ADDRESS>
- Added a big set of corner name and location data thanks to Scoops' hard work
- Overhauled yellow flag logic for sector yellows and local yellows
- Read times accurate to hundredths of a second in some circumstances
- Added oval-specific behaviours (enabled per-track with a flag in trackLandmarks.json) - ignores brake and left side tyre temps, estimates tyre wear from right side tyres only
- Added an experimental 'realistic mode' option - enabling this supresses some messages based on car class and track (e.g. spotter is off at start of session when not on ovals, older car classes have less telemetry based info like tyre temps) - this is very much 'work in progress'; added per-car class behaviours for yellow flag phrasing (e.g. pace car vs safety car) and last lap message (e.g. "white flag" for last lap only applies to Indy and NASCAR cars)
- Added 'force update check' button
Version <IP_ADDRESS>
- Fixed AC plugin after 1.14 update
Version <IP_ADDRESS>
- Fixed a silly bug in the legacy R3E blue flag detection (used when flag rules are disabled)
Version <IP_ADDRESS>
- Automatically switch between yellow and blue flag implementations in R3E depending on whether flag rules are enabled in-game
- Added some more incident calling and yellow flag options
- Added button mapping and voice command to suspend and enable yellow flag messages - enable with "give me yellows", "tell me yellows", "give me incident updates" or "give me yellow flag updates". Disable with "no more yellows", "stop incident updates", "don't give me yellows" or "don't tell me yellows"
- Fixed the "where is Bob?" voice message response in qual and practice sessions
Version <IP_ADDRESS>
- Added R3E Mantorp Park (long), Norisring and Sachsenring corner data
- A bit more R3E flag tweaking
Version <IP_ADDRESS>
- Skip 'dead' opponent data copies coming from PCars (should fix a few issues with inaccurate opponent data)
- Added R3E Hungaroring corner data
- Made opponent incident detection less sensitive and added an option to disable it (enable_simple_incident_detection)
- Reworked opponent lap and sector handling to fix incorrect sector time and pace reports (all games)
- Tweaked R3E yellow flag reporting to allow status changes to settle before reporting
Version <IP_ADDRESS>

- Added installer for game specific plugins (AC, AMS / RF1 and RF2) - the app now offers to copy the required plugin files to the games' install directory if they're missing or out of date
- extended incident reporting logic and sounds to allow for multiple involved drivers to be reported (if we have the driver name sounds) or 'pileup' warning if 4 or more drivers are stopped in the same corner
- added more corner names
- opponent tracking fixes for PCars
- loads and loads of bugfixes and improvements
Version <IP_ADDRESS>

- Added corner names to some calls on several tracks (this is will a work-in-progress)
- Revised RF2 and AMS opponent data handling to fix missing gap messages
- More work on AMS session end bugs
- Added better reporting of yellow flags for AMS and RF2 - the app will sometimes tell you who's involved in the incident and what corner the incident is in

Version <IP_ADDRESS>
- Integrated personalisations - the app will ask you to download a new "Personalisations" sound pack. When this is complete the "My name" drop down box (top right) has a long list of names the app can use when addressing you. This replaces the old method of manually unpacking a prefixes_and_suffixes folder to the app's sounds
- Work-around for Assetto Corsa sometimes giving out of date position information
- Disable multi-class code for RF1 based games because the vehicle type data from Automobilista is too vague (things like "Ford" and "Peugeot")
- Ported RF2 full course yellow and sector-specific yellow flag announcements to Automobilista
- Removed irrelvant pit window messages from RF1 based sims - in offline sessions, if a pit schedule is defined the app will call "box now" in accordance with this schedule (assuming equal stint lengths) - this can be disabled with enable_ams_pit_schedule_messages property
- Fixed cut track warnings playing on out laps in Automobilista
Version <IP_ADDRESS>
- Major overhaul of time reading (English sound pack - users of the Italian sound pack are unaffected)
- Added RF2 caution period and yellow flag events

Version <IP_ADDRESS>
- More pit window logic fixes for PCars
- Don't play pre-lights messages in PCars when the race is a fixed time
Version <IP_ADDRESS>

Sylvanian Families Celebration Timbertop Bear Family
Biography Information
Father Taylor Timbertop is a great big softy who adores his children, showering them with hugs and kisses whenever he gets the chance. He is always ready to change a nappy or help with homework, not that he is very good at either.

Older Brother Birch Timbertop is a great explorer; he knows every path, trail, cave, hollow tree and inch of the Sylvanian woods. He is adding all this knowledge to the collection of maps and diagrams that he is busily creating.
Older Sister Ivy Timbertop loves sewing and needlepoint. The first shirt she made was for her father; it was not one of her better creations! Taylor claims it's his favourite shirt and would never take it off, if Rose didn't insist on washing it!
Younger Brother Bud Timbertop is very keen on all types of sport. Whether it's swimming, running, jumping, rugby or tennis. Bud is always the first in line. He spends every spare moment training for this or that sport, all in the hope that one day he'll win a race or game and therefore a silver cup, which he would give to his mother.
Younger Sister Daisy Timbertop wants to be older so she can cook without her mother's help or sew without her sister's help. Maybe, if she were older and taller, her father would stop calling her 'his little cherub!'
Baby brother Burl Timbertop takes after his oldest brother, Birch, in that if you let him loose in the house he goes off exploring. He's been found in every nook and cranny, including inside the broom cupboard and under the table. He was even once found inside the grandfather clock!

ABOUT THE PROJECT
A pretty basic and open source implementation of HEROKUAPP's API for the better game of the trilogy, Age Of Empires II.
It includes basic info about the different Civilizations, Units and Structures of the game.
basically, you have two options for each category: You can individually search for them or you can take a dive into each of the lists

equals()
that access
non-final
variables. Such access may result in equals()
returning different results at different points in the object's lifecycle, which may in turn cause problems when
using the standard collections classes.
Example:
public class Person {
private String lastName;
@Override
public boolean equals(Object obj) {
...
Person other = (Person) obj;
if (lastName == null) {
if (!lastName.equals(other.lastName)) {
return false;
...
}
}

Related to the matrix representation of the Hamiltonian of the quantum system.
The Hamiltonian matrix itself is a public member of this class and is row-wise distributed among processing elements. For the Node communicator approach, the row-wise distribution of the matrix is retained, the only difference is the way the matrix elements are computed. See Section 3.1 (Node communicator) of the manuscript in /docs for more details.
| SparseOpNC::SparseOpNC | ( | const EnvironmentNC & | env, |
| const BasisNC & | basis | ||
| ) |
Creates an instance of class SparseOp.
| env | An instance of the class Environment. |
| basis | An instance of the class Basis. |
This is the only available constructor of this class. After creating an instance of this class one can call the construct_AA_hamiltonian(...) method to introduce parameters into the matrix The matrix itself is a public member of the class, row-wise distributed across processing elements. Please refer to Figure 1 and Section 3 (Hamiltonian matrix construction) of the manuscript in /docs for more information.
| SparseOpNC::~SparseOpNC | ( | ) |
Destructor.
Deallocates and destroys the Hamiltonian matrix, no need to call MatDestroy() on the matrix.

| double | V, | ||
| double | t, | ||
| double | h, | ||
| double | beta | ||
| ) |
Allocates memory and inserts elements to Hamiltonian matrix.
This should be called after creating an instance of SparseOp and before using time-evolution routines. The member HamMat is a matrix of type MATMPIAIJ from PETSc, for which memory is preallocated, distributed and elements are added by this routine. The main communication described in Algorithm 5 and Section 3.1 (node communicator approach) in the manuscript located in /docs is used in this routine.
|
private |
Computes the number of non-zero elements.
For good performance, the sparse matrix that represents the Hamiltonian of the system has to be preallocated in memory. This routine is called internally by contruct_AA_hamiltonian() to allocate memory for the matrix. The main communication procedure described in Section 3.1 (node communicator approach) and Algorithm 5 of the manuscript in /docs is implemented here.

Hello, a Little question :
i have a property truc : ∃ (s : S ) (u : U), blabla
it's possible obtain directly s, u, hyp_blabla
for the moment i do 2 line :
cases truc with s h_s, cases h_s with u hyp_blabla,
I'm sure this is possible but i don't remember :confused:
rcases truc with \<s, u, hyp\>
ohhh my bad : i use rcases truc with ⟨s, u hyp⟩,
i forget the ,
stupid me !!!
Thx Kevin !
I watched 20 undergraduates playing a preliminary version of the natural number game last year and they always forgot the comma :-)

This puzzle is a scheduling problem. Given the start and end dates of several events, you have to compute the maximum number of events that will be able to take place without overlapping. A well know algorithm, Earliest Deadline First running in O(n log n) gives the optimal schedule, then you only have to count the total number of scheduled events.
# Stores each calculation start and end dates, then sorts calculation by end date calcs, lastCalc, result = [], 0, 0 for i in range(input()): start, duration = [int(j) for j in raw_input().split()] calcs.append((start, start+duration)) lastCalc = max(lastCalc, calcs[i][1]) calcs.sort(key=lambda c: c[1]) # fill a timeline in which a free day is a 0, and a busy day a 1 with EDF timeline = [0] * lastCalc for c in calcs: if not 1 in timeline[c[0]:c[1]]: result += 1 timeline[c[0]:c[1]] = [1] * (c[1]-c[0]) print(result)
