Is this provable:
import data.multiset example (C : multiset ℕ) : decidable (∃ a : ℕ, a ≥ 4 ∧ a ∈ C) := sorry
and if so, is there a cheap proof? I tried doing it by hand and ended up with a horrible heq goal :-/
yes it is provable
might want to destruct C
Isn't membership in multisets decidable? You combine that fact with decidability of existentials on finite ranges
If I use lists I end up with
C1 C2 : list ℕ, Crel : setoid.r C1 C2 ⊢ eq.rec (list.rec (is_false _) (λ (n : ℕ) (L : list ℕ), decidable.rec (λ (D : ¬∃ (a : ℕ), a ≥ 4 ∧ a ∈ ↑L), dite (3 < n) (λ (h : 3 < n), is_true _) (λ (h : ¬3 < n), is_false _)) (λ (D : ∃ (a : ℕ), a ≥ 4 ∧ a ∈ ↑L), is_true _)) C1) _ = list.rec (is_false _) (λ (n : ℕ) (L : list ℕ), decidable.rec (λ (D : ¬∃ (a : ℕ), a ≥ 4 ∧ a ∈ ↑L), dite (3 < n) (λ (h : 3 < n), is_true _) (λ (h : ¬3 < n), is_false _)) (λ (D : ∃ (a : ℕ), a ≥ 4 ∧ a ∈ ↑L), is_true _)) C2
If I use multiset.rec
I end up with
a a' : ℕ, m : multiset ℕ, b : decidable (∃ (a : ℕ), a ≥ 4 ∧ a ∈ m) ⊢ decidable.rec (λ (H : ¬∃ (a : ℕ), a ≥ 4 ∧ a ∈ a' :: m), dite (3 < a) (λ (h : 3 < a), is_true _) (λ (h : ¬3 < a), is_false _)) (λ (H : ∃ (a : ℕ), a ≥ 4 ∧ a ∈ a' :: m), is_true _) (decidable.rec (λ (H : ¬∃ (a : ℕ), a ≥ 4 ∧ a ∈ m), dite (3 < a') (λ (h : 3 < a'), is_true _) (λ (h : ¬3 < a'), is_false _)) (λ (H : ∃ (a : ℕ), a ≥ 4 ∧ a ∈ m), is_true _) b) == decidable.rec (λ (H : ¬∃ (a_1 : ℕ), a_1 ≥ 4 ∧ a_1 ∈ a :: m), dite (3 < a') (λ (h : 3 < a'), is_true _) (λ (h : ¬3 < a'), is_false _)) (λ (H : ∃ (a_1 : ℕ), a_1 ≥ 4 ∧ a_1 ∈ a :: m), is_true _) (decidable.rec (λ (H : ¬∃ (a : ℕ), a ≥ 4 ∧ a ∈ m), dite (3 < a) (λ (h : 3 < a), is_true _) (λ (h : ¬3 < a), is_false _)) (λ (H : ∃ (a : ℕ), a ≥ 4 ∧ a ∈ m), is_true _) b)
I assume I'm doing something wrong.
I think there might be some lemmas that one could use
bounded existential
Isn't membership in multisets decidable? You combine that fact with decidability of existentials on finite ranges
example (D : multiset ℕ) (d : ℕ) : decidable (d ∈ D) := by apply_instance
works
@Kevin Buzzard shouldn't you be watching the world cup?
Oh, has it started?
:o
it's already 67 minutes
You can try this:
instance {α : Sort*} (P : α → Prop) (C : multiset α) : decidable (∃ a ∈ C, P a) := sorry example (C : multiset ℕ) : decidable (∃ a : ℕ, a ≥ 4 ∧ a ∈ C) := suffices this : decidable (∃ a ∈ C, a ≥ 4), by { resetI, apply @decidable_of_iff _ _ _ this, apply exists_congr, intro, tauto }, by { apply_instance }
well you want P to be decidable
Yes, that's right
I don't understand how to use this code. If I comment out the instance then there's an error in the final apply_instance
but if I look at what needs to be proved at that point it seems to be decidable (∃ (a : ℕ) (H : a ∈ C), a ≥ 4)
which is exactly my question I think?
Ok, one second I'm filling in that instance
Add this before Simon'd code
instance decidable_exists_multiset {α : Type*} (s : multiset α) (p : α → Prop) [decidable_pred p] : decidable (∃ x ∈ s, p x) := quotient.rec_on s list.decidable_exists_mem (λ a b h, subsingleton.elim _ _)
Nice! that's better than what I have
It would be worth pushing to mathlib I think along with a finset
counterpart and decidable universals for both
Will do.
Thanks!
Thanks to both of you! I cannot believe how much trouble Ellen's dots and boxes project is causing me :-)
What's that project?
She's formalizing some of the theory of dots and boxes

James Gosling: "There aren't a lot of people building IDEs (integrated development environments). And IDEs are generally targeted at low-end developers--people who are not experts at writing code. And if you look for tools that are oriented toward (those) people, you basically find nothing. The No. 1 tool (in that area) is Emacs, ..."
Amen to that. Why isn't there an IDE for the hardcore developer? Can't anyone improve on bash and emacs? Or maybe there is just no money to be made in doing so?

--- layout: page title: "Section 2: Dalvik Thread Model" ---
Our ultimate goal is to build a replayable Dalvik which can produce the same result as record execution as many times as we want. It is easy to do in a sequential program the only need of which is to record all the non-determinisms coming from environment, such as time or random number. However, this is not the case in nowadays multi-thread programs. Because of the interleaving of the threads, program can behave differently even if the environment variables are the same.
Take the following code as an example:
counter = 1;
thread1:
void add()
{
counter++;
}
thread2:
void mul()
{counter *= 2;}
When the above code is running, there are two scenarios: function add() run first and then mul() or vice versa. In the first condition, the counter value is (1+1)*2=4, while in the latter condition, the answer will be 1*2+1=3. So different interleaving will cause different result in a multi-thread environment.
In this lab, we will go inside thread model of Dalvik and design a way to mapping the threads between record and replay.
In the follwing of our lab, we will use a app called inc-mul-counter as our benchmark which can download HERE. In this app, there are two group of threads. Each group contains several threads doing the same work. One group is called increase group who will add one to a global counter. The other group is called multiply group. The function of the threads in it is multiply the counter by 2. All the operations to the counter are sequentialized by the same lock, which means there is no data-race.


Officials: Boy, 9, killed by father in hunting accident
by The Associated PressORANGEBURG, S.C. — Officials say a 9-year-old boy was accidentally killed by his father while hunting in South Carolina on Thanksgiving.
News outlets report Colton Williams was fatally shot Thursday in Springfield in Orangeburg County.
The South Carolina Department of Natural Resources says relatives told investigators that Williams was out rabbit hunting with his dad and a family friend when his father accidentally shot him.
Williams was a fourth-grader who went to Kelly Edwards Elementary School in Williston.
The school district wrote on its Facebook page that counsellors will be at the school Monday and will be available throughout the week and longer if needed.

Description of Lists and Links
I created a folder called listsandlinks and made a new index.html inside the folder. Then I made 5 links with helpful websites that help you and me with web design. Then I made a link to my old index.html and on that html I made a link to the listandlinks website
-
Create a new folder called "listsandlinks" in your repository folder.
Inside listsandlinks create a file called "index.html" and a file called "main.css"
In index.html create an ordered list of step by step instructions to create a new webpage on the production server.
Also create an unordered list of 5 or more links to websites with useful webdesign related information.
In the nav section, create an unordered list of links with a link back to your main index page.
In your main index.html file in public_html, add an unordered list of links to the nav section with a link to "listsandlinks".
In your old index.html, add an article with a heading and a paragraph description of this assignment. Also add an unordered list that contains this list of requirements.
Turn in your work.


My story includes a multitude of blessings in the form of three lovely grown sons, cherished family, friends and a wide variety of experiences both sweet and challenging.
These experiences have sensitized me to both joy and sorrow.
My intention is to utilize this sensitivity in my work with clients.
For more of my story, journey here.
About what I do
Myofascial release (MFR) is a slow and gentle therapy for calming the body’s nervous system and releasing fascial restrictions. A collaborative method, MFR can access a variety of issues, therefore good communication between client and therapist is key. I’m happy to answer questions.
Curious to see what real fascia looks like? Check out this brief video.

How I got here...
While living in Grand Rapids Michigan in 2014, I became a Physical Therapy client after a hamstring injury. My PT, Rachel Davies, had been trained in the John Barnes’ Myofascial Release (MFR) approach. My life was in transition physically and emotionally at the time. MFR was a very supportive modality and it fit in well with the mindful, body-centered psychology (Hakomi) training which I was undertaking. Rachel sensed my potential affinity for MFR work and suggested that I consider it as a career path. Although I had never even had a pleasant massage in my life, with Rachel’s encouragement and an impulse to be of service, I went to massage school in Kalamazoo Michigan and became a licensed massage therapist. I graduated in 2016, then returned to my home state of Texas. I have taken 184 hours of continuing education since that time, all in the John Barnes’ Myofascial Release method.

For science:
“non-reproducible single occurrences are of no significance to science”
For our careers:
“I have spent nearly a decade working on the concept of ego depletion […] The problem is that ego depletion might not even be a thing.”
Produce reproducibile research that can be replicated easily.
Published research is not representative.
Under the null, how likely is the observed data?
Says nothing about assumptions+hypothesis validity.
Even with a pre-stated hypothesis and no conscious p-hacking, each design choice is a fork in the path towards a finished paper.
If observed significance influences these choices, p-values are meaningless.
Public demonstration of precedence
Pre-registration — Before accessing data
Pick a path through the garden and stick to it.
Focus: sample selection, estimation
Also: motivation, literature
Could be: your paper before results
(maybe extension of grant proposal)
I’ve gotten an absurd number of requests for sensitivity analyses for strictly pre-specified empirical work. The existing norm appears to keep me from looking for unexpected results while providing no protection from readers or reviewers who want to dig through the data trying to kill off empirical results they don’t agree with.
If you cannot pre-pick one analysis, study all.
rowmeans <- function(x, y) {
# Calculate pairwise means of numeric input vectors.
# Input: two vectors of equal length; "x", "y"
# Output: one vector "out" of means.
if (length(x) != length(y)) stop("x, y have unequal lengths")
# Create empty vector to fill with rowmeans
out <- vector("numeric", length = length(x))
for (i in seq_along(x)) {
# For each row, calculate mean of x and y and store in z.
out[i] <- mean(c(x[i], y[i]))
}
return(out)

Context is designed to share data that can be considered “global” for a tree of React components, such as the current authenticated user, theme, or preferred language
A thunk is a function that wraps an expression to delay its evaluation.
...
Thunks are the recommended middleware for basic Redux side effects logic, including complex synchronous logic that needs access to the store, and simple async logic like AJAX requests.

function increment() {

dispatch(increment());
}, 1000);

redux-saga is a library that aims to make application side effects (i.e. asynchronous things like data fetching and impure things like accessing the browser cache) easier to manage, more efficient to execute, easy to test, and better at handling failures.

Ballan crash leaves man in critical condition
by Ben HopkinsUPDATE: 10am
A man in his 40s who was airlifted to the Royal Melbourne Hospital in a critical condition following a crash in Ballan on Sunday night has had his condition improve.
A media spokesperson from the RMH told The Courier the man's condition has been downgraded from critical to serious.
EARLIER: 7am
A man has been flown to the Royal Melbourne Hospital in a critical condition after a crash on Sunday evening.
Emergency services were called to the Ballan-Daylesford Road in Ballan just after 7pm on Sunday to reports of a single-vehicle crash.
Fire crews from Gordon, Ballan and Myrniong turned out to the incident after reports the car may have been on fire following the crash.
Paramedics treated a man at the scene, aged in his 40s, for head injuries.
He was flown by air ambulance helicopter to Royal Melbourne Hospital in a critical condition.


Reader’s Voice: Chiefs Will Win The League This Season!
by SL Social“No need to argue, Chiefs will win the Absa Premiership this season. You can tell from their play that they will be the champions. What a player we have in Zuma the boy is a special, he’s similar to Neymar. Thumbs up to all Amakhosi.”
These are the bold claims made by SL Supporter and avid Kaizer Chiefs fan @ patrick shikwambani and in his defence, he has reason to feel this buoyant, following his team’s resurgence this season.
Ernst Middendorp’s men recorded their fifth consecutive win by overcoming a stubborn Chippa United on Wednesday evening. The side from Naturena sit pretty atop the log with a seven-point gap over Mamelodi Sundowns, who have a game in hand.
What is even more impressive about Chiefs’ 2-0 win is that Ernst Middendorp rested a number of his regulars for the clash, something SL Supporter @ Zizuness Moshou feels will go a long way in helping their championship plight this season.
“All we do is win, win, win no matter what. Great performance from our makeshift team. Well done guys it shows we do have players who can still come in and win us games.”
Download The Soccer Laduma Social Media App & Earn Airtime for Selfies!
While Middendorp rightfully deserves the credit for Chiefs’ turnaround, SL Supporter @Zam d king Buccaneer, feels that Bobby Motaung deserves a special mention too.
“I still do not hear people praising Bobby for having a backbone and sticking with Middendorp after the humiliating loss to TS Galaxy and missing out on a top eight spot. Give credit where it's due. Come on people.”
Rival fans like SL Supporter @Dangaga feels that it is the men from Naturena who have all the confidence in the world, and have the ability to beat Orlando Pirates for the second time in a matter of days.
“I am a Sundowns fan and hate to admit that killer Chiefs are on fire and if they can get past Pirates, their confidence will be sky-high, meaning the league will be theirs to lose.”
Having seen their form this season, do you think Kaizer Chiefs can overcome Pirates once again this weekend, or will the Buccaneers bite back?


VDV - VDV-451/VDV-452/INTREST Data Format
(GDAL/OGR >= 2.1.0)
This driver can read and create text files following the VDV-451 file format, which is a text
format similar to CSV files, potentially containing several layers within the same file.
It supports in particular reading 2 "profiles" :
The generic reader/writer for VDV-451/VDV-452 can support arbitrarily large files. For
the INTREST data case, for combined layers in a single file, the driver ingests
the whole file in memory to reconstruct the Link layer.
Interleave reading among layers is supported in files with multiple layers.
Creations issues
The driver can create new layers (either in the same file, or in separate
files in the same directory). It can append a new layer into an existing file, but
it cannot append/edit/delete features to an existing layer, or modify the
attribute structure of an existing layer after features have been written.
The following dataset creation options are available:
- SINGLE_FILE=YES/NO. Whether several layers should be put in the same
file. If NO, the name is assumed to be a directory name. Defaults to YES.
The following layer creation options are available:
- EXTENSION=string. Extension used when creation files in separate layers,
i.e. only for SINGLE_FILE=NO dataset creation option. Defaults to x10.
- PROFILE=GENERIC/VDV-452/VDV-452-ENGLISH/VDV-452-GERMAN. Defaults to GENERIC.
Describe which profile the writer should conform to. VDV-452 will restrict layer and field names
to be the one allowed by the VDV-452 standard (either in English or German).
VDV-452-ENGLISH and VDV-452-GERMAN will restrict the VDV-452 to the specified
language. The configuration file describing VDV-452 table and field names is
vdv452.xml
located in the GDAL_DATA directory.
- PROFILE_STRICT=YES/NO. Whether checks of profile should be strict.
In strict mode, unexpected layer or field names will be rejected. Defaults to NO.
- CREATE_ALL_FIELDS=YES/NO. Whether all fields of predefined profiles
should be created at layer creation. Defaults to YES.
- STANDARD_HEADER=YES/NO. Whether to write standard header fields (i.e
mod, src, chs, ver, ifv, dve, fft). If set to NO, only explicitly specified HEADER_xxx
fields will be written. Defaults to YES.
- HEADER_SRC=string: Value of the src header field. Defaults to UNKNOWN.
- HEADER_SRC_DATE=string: Value of the date of the src header field as DD.MM.YYYY. Defaults to current date (in GMT).
- HEADER_SRC_TIME=string: Value of the time of the src header field as HH.MM.SS. Defaults to current time (in GMT)
- HEADER_CHS=string: Value of the chs header field. Defaults to ISO8859-1.
- HEADER_VER=string: Value of the ver header field. Defaults to 1.4.
- HEADER_IFV=string: Value of the ifv header field. Defaults to 1.4.
- HEADER_DVE=string: Value of the dve header field. Defaults to 1.4.
- HEADER_FFT=string: Value of the fft header field. Defaults to '' (empty string).
- HEADER_xxx=string: Value of the xxx (user defined) header field.

Details on how to use the BasicBlurView. This is a convenance wrapper around the Box Blur functionality of GPUBlurImageView
The BasicBlurView supports a majority of the standard Ti.UI.ImageView properties and provides one new blur related property, blurRadius.
image : String/Titanium.Blob/Titanium.Filesystem.File
Image to blur then display, defined using a local filesystem path, a File object, a remote URL, or a Blob object containing image data. Blob and File objects are not supported on Mobile Web.
blurRadius : Number
The amount of blur radius that should be applied to the image
Example ~~~ var vwTest = mod.createBasicBlurView({ width:Ti.UI.FILL, height:Ti.UI.FILL, blurRadius:5, image: 'your-image-here.png' }); ~~~


The Philadelphia Eagles Have Released A Veteran WR
by Matt HladikWide receiver Jordan Matthews played much of the game for the Philadelphia Eagles on Sunday. On Monday, the team cut him.
Matthews signed with Philly for a third stint earlier this month. He played in two games, making four receptions for 33 yards.
The Eagles have had problems at the receiver position for much of the season, but Matthews’ release could signify that the Alshon Jeffery is close to returning. Jeffery has missed three games due to injury.
Also, rookie J.J. Arcega-Whiteside may be poised to take on a larger role as well.
The Eagles drafted Matthews out of Vanderbilt in 2014, and he played his first three seasons with the team. He played with the Buffalo Bills in 2017.
Matthews also had a brief stint with the Eagles in 2018.

Yes, right. What you'll mainly have to implement for variables is the
function FloatVarImp<...>::spec.  You have to make sure that this vti is
unique for each FloatVarImp instance.

Hm, I don't know. An ActorSpec just must be able to represent what
the system uses, it doesn't have to be platform-independent. The idea
is that an ActorSpec just lets you look inside the propagator. If you
want to communicate the specs, e.g. over the network, you'll have to
make sure that a platform-independent representation is used. E.g.,
we can use boost serialization to turn ActorSpecs into strings. The
serialization classes should allow platform-independent transfer of
e.g. doubles.
So, I guess we should add support for double in ActorSpec.

No, that's all there is to it ;-) Just add a type method, that's how
we do it, too.

fork
OS/161 Reference Manual
Name
fork - copy the current process
Library
Standard C Library (libc, -lc)
Synopsis
#include <unistd.h>
pid_t
fork(void);
Description
fork duplicates the currently running process. The two copies are
identical, except that one (the "new" one, or "child"), has a new,
unique process id, and in the other (the "parent") the process id is
unchanged.
The process id must be greater than 0.
The two processes do not share memory or open file tables; this state
is copied into the new process, and subsequent modification in one
process does not affect the other.
However, the file handle objects the file tables point to are shared,
so, for instance, calls to lseek in one process can affect the other.
Return Values
On success, fork returns twice, once in the parent process and once in
the child process. In the child process, 0 is returned. In the parent
process, the process id of the new child process is returned.
On error, no new process is created, fork only returns once, returning
-1, and errno is set according to the error
encountered.
Errors
The following error codes should be returned under the conditions
given. Other error codes may be returned for other errors not
mentioned here.
| | |
| EAGAIN | Too many processes already exist. |
| ENOMEM | Sufficient virtual memory for the new
process was not available. |


A couple months ago I posted here about some of our experiences with Varnish Cache as an HTTP accelerator. By and large I have been very impressed with Varnish.  Apache would get wedged once it had reached it's MaxClients limit, whereas Varnish seems to happily queue up thousands of requests even if the backend (Apache) is going slowly.
However, after a while we started running into other problems with Varnish, and I found the probable answer in a bug report at the Varnish site. It turns out that Varnish was written with a 64 bit system in mind. That isn't to say that it won't work nicely on a 32 bit system, just that you better not expect high server load, or else you'll start running into resource limitations in a hurry. This left us with about 2 options: Move to 64 bit or ditch Varnish for something like Squid. Seeing as how I was loathe to do the latter, we decided to go 64 bit, which in any case is another logical step into the 21st century.
The problem was that our servers are co-located in data centers around the country. We didn't want to hassle with reprovisioning all of the them. Asheesh did the the first remote conversion based on some outdated document he found on remotely converting from Red Hat Linux to Debian. It went well and we haven't had a single problem on that converted machine since. Varnish loves 64bit.
I have now converted two more machines, and this last time I documented the steps I took. I post them here for future reference and with the hope that it may help someone else. Note that these steps are somewhat specific to Debian Linux, but the concepts should be generally applicable to any UNIX-like system. There are no real instructions below, so you just have to infer the method from the steps. See the aforementioned article for more verbose, though dated, explanations. BE WARNED that if you make a mistake and don't have some lovely rescue method then you may be forced to call your hosting company to salvage the wreckage:

When I'm not at the gym, I follow a follow a wide variety of shows with my favorite show being "How I Met Your Mother", I enjoy cooking for my friends and family, and I spend a large amount of my free time exploring the latest technology projects and DIY furniture.


It goes something like this*:
W: ‘I’m not one of those people’.
M: ‘One of what people?’
You know, the kind of people who wouldn’t drink coffee at a petrol station at all, let alone on a first date. Ok, so there are principles involved.
M: ‘But it’s not just any coffee, it’s…’ coffee of a very specific brand.
W: Hmmm, but is it organic?
M: Yes, my princess, they have organic options
W: Oooh, you’re a classy guy.
Not that I was dying to try it or anything, but now I’m totally off this brand of coffee. I mean, what. Just, what. How. WHY?!
Folks, please chime in. Is petrol station coffee a turn on for a first date as long as it has an organic option?
The Coco Nails ad is starting to sound pretty good.

The Collections package contains a set of Java classes that extend or augment the Java Collections Framework. This developers guide seeks to set out rules for the naming of classes and methods within the package. The purpose of this, as with all naming standards, is to improve the coherency and consistency of the whole API.
The philosophy of the naming standards is to follow those of java.util.Collections.
Collection interfaces are new types of collections not included in Java.
Examples include Bag
and SortedBag
. These interfaces
shall:
Collection implementation are new implementations of collection interfaces.
Examples include DoubleOrderedMap
and DefaultMapBag
.
These interfaces shall:
Utility classes provide additional functionality around an interface and its basic implementations. Examples include CollectionUtils and ListUtils.
Each class shall follow the naming pattern XxxUtils where Xxx relates to the
object being returned by the class, for example ListUtils
and
BagUtils
. Variations on a theme (SortedBag
as opposed
to Bag
) will be dealt with in one Utils class. Each Utils class
shall:
Where the method in a Utils class is a decorator, the name shall consist of
an adjective followed by the collection type. Typically such adjective is
formed by appending an -ed suffix (meaning "having"/"characterized by") to the
word describing the type of decorator. For example,
synchronizedMap(Map)
or predicatedSet(Set)
.
Occasionally, such construct is awkward and a more suitable adjective can be
used instead. For example, lazyList
,
unmodifiableList
.
These decorators should be implemented either as non-public, static, inner classes, or as public classes in a subpackage. If a subpackage is used, the constructors should be protected and a public static decorate() method provided on each class for construction.
Commons Collections follows similar style rules to many other Java open source projects, and the Sun conventions. Some specific conventions are:
And rememeber, the commons-dev mailing list is there for any discussions or queries about patches or new additions to collections.

I wish happy holidays and some good days, with family or friends.
As you maybe have noticed i am a little bit busy so BBLog haven't got noticable updates since a few weeks.
Next big update is expected for BF Hardline release, early 2015, as the current information says.
So, see you next year and stay tuned with us.
Nearly 5 and a half million downloads, that's what i expect from a christmas present :)

Security¶
Starting with CruiseControl.NET 1.5.0, it is possible to add security to a CruiseControl.NET instance.
This page provides an overview of security for CruiseControl.Net on the server side. It includes how security works and why it might be needed. This includes defining the different parts of security and how they interact.
What is security?¶
The goal of security is to protect the system from unauthorized (and potentially malicious) users while still allowing authorized users the freedom to do their tasks.
As such this includes a number of different areas. In general security can be broken down into the following areas:- Authorisation: ensuring the user only has access to what they are allowed to use.
- Authentication: validating that a user is who they say they are.
- Auditing: logging what a person does, including the results of any attempted actions that failed (e.g. due to insufficient authentication or authorization)
The first two items can be thought of as active or preventive security. They stop the user from doing things they shouldn't. The third area is more of a passive area, but it is critical for preventing future attacks and diagnosing what has happened.
While there are other areas of security, these are the three areas that have been implemented for CruiseControl.Net.
How does security work for CruiseControl.Net?¶
Security for CruiseControl.Net has been implemented for the three areas listed above. All of these security areas has been implemented at the server level (for both console and service modes).
The security framework is designed to be configured in ccnet.config - otherwise the system will be treated as an open system (e.g. no security).
Additionally the framework is extensible - should the current components be insufficient for the security needs they can be replaced with custom components.
Authentication¶
Authentication is defined at the server-level. The administrator needs to define one or more users for the system.
These users can be validated by user name, user name/password or against an active directory domain.
Authorisation¶
Authorisation is defined initially at the project-level. This is because each project can have a separate set of permissions.
However, permission sets can also be defined at the server-level, and the project merely references these permission sets. This allows a common set of permissions to be defined for the entire server, with the projects then opting in as desired.
Auditing¶
Auditing is also defined at the server-level. This is to enforce consistent auditing across the entire server.
Auditing consists of two parts: one or more writers and a reader.
Each writer is responsible for writing audit information to a log somewhere. It is possible to configure multiple writers to allow writing information to different places.
A reader is responsible for reading an existing audit log so the information can be used in other places within CruiseControl.NET (e.g. the dashboard, etc.) Unlike the writers, there can only be one reader - otherwise CruiseControl.NET would get confused. The audit log that the reader reads from is referred to as the primary audit log.
Default Settings¶
The default server security manager is Null Server Security - this turns off security at the server level.
The default project security is Inherited Project Security - this will inherit all security settings from the server level.
Extensions¶
Security has been designed with extendability in mind. It has a large number of extension points to (hopefully) all possible scenarios.
Extending security is converted in Security Extension Points

ecfg
- JSON, YAML, or TOML file with asymmetric-key-encrypted values
An ecfg
file is syntactically a json
, yaml
, or toml
file, but with a few minor semantic additions described below.
Each ecfg
file must have a key at the top level named
_public_key
. This implies that the top-level structure must be a
hashmap, not an array.
The _public_key
key must have a string value, which is a hex-encoded
32-byte (totalling 64 ASCII bytes) public key as generated by
ecfg-keygen(1).
By convention, _public_key
should be the first key in the file.
A value is considered encryptable if:
It is a string literal (numbers, true, false, null all remain unencrypted);
It is not an object key (ie. not immediately followed by a ":" in JSON, etc.);
Its corresponding object key did not begin with an underscore ("_").
Take special note of point 3. This is the reason _public_key
isn't
encrypted, and can be used to construct metadata schemes. For example, in the
excerpt below, only the values for rotation_password
and secret
will
be encrypted.
"my_secret": {
"_description": "API key for foocorp",
"_rotation": "https://example.com/foocorp/apikey",
"_rotation_username": "admin",
"rotation_password": "password",
"secret": "123123123123123123123"
}
Also note that this underscore "unencryptable" attribute is not heritable. For
example, the password in this excerpt will
be encrypted.
"_unencryptable": {
"password": "encrypted anyway"
}
When a value is encrypted, it will be replaced by a relatively long string of the form "EJ[V:P:N:M]". The fields are:
V
(decimal-as-string int)
Schema Version, hard-coded to "1" for now
P
(base64-encoded 32-byte array)
Public key of an ephemeral keypair used to encrypt this key
N
(base64-encoded 24-byte array)
Nonce used to encrypt this key
M
(base64-encoded variable-length array)
Raw ciphertext
ecfg
values are encrypted using a Curve25519 x Salsa20 x Poly1305-AES
public-key scheme. This normally implies use of NaCl
or libsodium
.
NaCl libraries generally take keys as a sequence of raw bytes, but they're embedded in ecfg files as hex-encoded strings, so we need a routine to convert them:
base16_to_raw(key : string) -> []byte =
# convert e.g. "1234beef" into [0x12, 0x34, 0xBE, 0xEF] or whatever
# the particular NaCl implementation/binding wants.
When we write the final encrypted message according to the SECRET SCHEMA
section, we need to encode several sequences of raw bytes to base64, with
newlines removed:
encode(raw : []byte) -> string =
sub("\n", "", base64_encode(raw))
Building the message given the ciphertext and other input parameters is just string concatenation:
format(pub : []byte, nonce : []byte, ct : []byte) -> string =
"EJ[1:" + encode(pub) + ":" + encode(nonce) + ":" + encode(ct) + "]"
During encryption, an ephemeral keypair is generated and the public key is embedded in the encrypted message.
The final encryption routine combines accepts a plaintext string and a
hex-encoded public key extracted from the input document, returning a formatted
ecfg
message. The NaCl API calls here are loosely paraphrased.
encrypt(plaintext : string, peer_pub_hex : string) -> string =
peer_pub = base16_to_raw(peer_pub_hex)
(ephemeral_pub, ephemeral_priv) = NACL.crypto_box_keypair()
# 24 random bytes
nonce = NACL.randombytes(NACL.NONCE_BYTES)
# API here varies a lot depending on binding.
ciphertext = NACL.crypto_box(
plaintext,
ephemeral_priv, peer_pub, nonce
)
format(ephemeral_pub, nonce, ciphertext)
If multiple values are being encrypted at once, a single ephemeral keypair may be reused. It may make sense but is by no means necessary to use box precomputation if it's available.
To decrypt messages from a document, the caller must first retrieve the private key associated to the public key embedded in the document, then the message must be decomposed into the three encoded values. This is just the inverse of the process from the encryption section above: remove the "EJ[]" enclosure; split the message on ":", check that the version is 1, then base64-decode the remaining three components.
Given those three components (peer_pubkey
, nonce
, and ciphertext
), the
decryption routine looks like:
decrypt(
target_privkey : string,
peer_pubkey : []byte,
nonce : []byte,
ciphertext : []byte,
) -> string =
priv = base16_to_raw(target_privkey)
# like above, this API varies a lot by binding implementation.
NACL.crypto_box_open(
priv, peer_pubkey, nonce, ciphertext
)
ecfg(1), ecfg-encrypt(1), ecfg-decrypt(1), ecfg-keygen(1)

Step7: Create Your Own Exception
Objective
In this exercise you will create an OverdraftException that is
thrown by the withdraw method in the Account class.
Directions
Start by changing your working directory to /step7
on your computer. Create the banking directory. Copy the previous
Banking project files in this package directory.
Create the OverdraftException Class
- Create a public class, called OverdraftException, in the
banking.domain package. This class extends the Exception class.
- Add a private attribute called deficit that holds a double.
Add a public accessor called getDeficit.
- Add a public constructor that takes two arguments: message and
deficit. The message parameter should be passed to the
super class constructor. The deficit parameter initializes the
deficit attribute.
Modify the Account Class
Modify the witdraw method:
- Rewrite the witdraw method so that it does not return a value
(that is, void). Declare that this method throws the
OverdraftException.
- Modify the code to throw a new exception that specifies "Insufficient funds"
and the deficit (the amount requested subtracted by the current balance).
Modify the CheckingAccount Class
Modify the witdraw method:
- Rewrite the witdraw method so that it does not return a value
(that is, void). Declare that this method throws the
OverdraftException.
- Modify the code to throw an exception if necessary. There are two
cases that need to be handled. First, there is a deficit with no
overdraft protection from the savings account; use the message "No
overdraft protection" for this exception. Second, the overdraftProtection
amount is sufficient to cover the deficit; use the message
"Insufficient funds for overdraft protection" for this exception.
Compile and Run the TestBanking Program
You should see the following output:
Customer [Simms, Jane] has a checking balance of 200.0 with a 500.00 overdraft protection.
Checking Acct [Jane Simms] : withdraw 150.00
Checking Acct [Jane Simms] : deposit 22.50
Checking Acct [Jane Simms] : withdraw 147.62
Checking Acct [Jane Simms] : withdraw 470.00
Exception: Insufficient funds for overdraft protection Deficit: 470.0
Customer [Simms, Jane] has a checking balance of 0.0
Customer [Bryant, Owen] has a checking balance of 200.0
Checking Acct [Owen Bryant] : withdraw 100.00
Checking Acct [Owen Bryant] : deposit 25.00
Checking Acct [Owen Bryant] : withdraw 175.00
Exception: No overdraft protection Deficit: 50.0
Customer [Bryant, Owen] has a checking balance of 125.0


POULTRY IN MOTION
CHICKEN RUN
Directed by Peter Lord and Nick Park
Written by Lord, Park, & Karey Kirkpatrick
Voices of Mel Gibson, Julia Sawalha
UA North, De Vargas PG 85 min
Just when it was starting to look like comedy was plucked, along comes the funniest movie of the year to put it back on its perch. This will come as no surprise to fans of Nick Park and Peter Lord, the geniuses behind the Oscar-winning Wallace and Gromit shorts.
Park and Lord work in claymation, a process so slow and painstaking you can't imagine how they can find anything funny. But oh, do they! In their first feature-length film, produced through Dreamworks, they've created a hilarious spoof on WWII POW movies like The Great Escape. But you don't have to know the sources - Chicken Run is funny and endearing and completely entertaining in its own right.
The action takes place on the chicken farm of Mr. And Mrs. Tweedy (Tony Haygarth and Miranda Richardson), a grim stalag of barracks where chickens must produce or perish. Some of them take it lying down, but not Ginger (Julia Sawalha of TV's AbFab), a plucky little hen with escape in her blood. "So, laying eggs all your life and then getting stuffed and roasted, that's good enough for you, is it?" she demands, to which another chicken (Jane Horrocks of Little Voice) replies "It's a living."
When the Tweedys install a chicken pot pie machine, things get desperate - when out of the sky comes what looks like the answer to Ginger's prayers: Rocky the Flying Rooster (Mel Gibson), a refugee from a circus who calls himself "The Lone Free Ranger." She offers to hide him if he'll teach them all how to fly.
What makes Lord and Park's work so great is a deeply wonderful sense of humor, both verbal and visual. It's in the timing, in the characters, in the lines, in the lighting and the camera angles and the sets and the music (including the R&B classic "Flip, Flop and Fly".) In a world of computerized high-tech, this is basic, and brilliant.

Yes! Digging up the original images for coordinates or to assemble a multi-color image does take its time. But well-vetted, these objects show better than anything else the capabilites of DES of covering a lot of area to as of yet unreached depths. In other words, the collection of these objects is a great source for public outreach and the title slides of our upcoming DES presentations. And potentially, you might be able to discover something really new out there.
If that sounds like a job for you, please contact us.


The following is a true story, but with names changed.
When I work with clients to build software, I take the usual steps of understanding their needs, gathering requirements, learning about their customers, and so on. At this point I have a model on paper of roughly what the software is intended to do, so they get surprised when I immediately turn to database design.
"Who care about database design? What about mockups? What about workflows?"
Let me tell you about "Bob's Luxury Goods." I worked for this company many years ago and they had a retail store selling ... you guessed it ... luxury goods. They'd ask all customers for a billing address and if they had a different delivery address. At the database level, they had a "one-to-many" relationship between customers and addresses.
That was their first problem. A customer's partner might come into Bob's and order something and if the address was entered correctly it would be flagged as "in use" and we had to use a different address or deliberately enter a typo. Fortunately, addresses were case-sensitive, so many people had UPPER-CASE ADDRESSES.
We should have had a many-to-many relationship between customers and addresses so we could handle the case where more than one person would share the same address, but we didn't. Further, I was never allocated the time to fix the database because it was "cheaper" to remove the restriction on "flagged" addresses and allow a duplicate address to be used.
Naturally, being a luxury goods company, we had many repeat customers and sometimes they would move and if we didn't find the duplicate address, or the address with the "typo", we might update the address for one partner, but not the other. That was a headache, but it didn't happen frequently enough for management to worry about it.
That's when the marketing department had a brilliant, inexpensive idea. You see, we periodically did mass mailings of special events to our customers. Since we had the software to do mass mailings, why not import a mailing list of all addresses in high net worth areas and mail everyone about upcoming special events? So the company went ahead and bought a database with all of these addresses, but forgot to mention to me that I was supposed to implement this.
Except that every address record had the customer id embedded in it, so we couldn't enter an address without a customer.
"Curtis," they said, "just enter a dummy customer called 'Occupant' and attach all addresses to that."
Except you couldn't enter a customer without an order.
Except you couldn't enter an order without at least one item on it.
Except you couldn't enter an item unless it was listed in inventory.
Except that reserved the "inventory" item and made it unavailable.
Except, except, except ...

Then, and only then, could I write the code to provide "generic" mass mailings. Management decided it was easier to hire an outside company to handle the mailing list for them.
If they had simply had a proper database design up front, they could have reused their existing system with little trouble.
That's what bad database design costs you and why I usually start with that before writing my software.
Note: if you're not familiar with database design, here's a talk I give where I make it fairly simple to understand. I mostly avoid big words.

An adaptation of Mandyn to the problem of Newton Fractals, largely inspired by this page about it. As with Mandyn, the idea is to watch the fractal grow iteration by iteration, representing the value at each point using colour.
This particular fractal uses the Newton-Raphson method to find roots of a complex polynomial, which for convenience is (z-c0)(z-c1)... - the idea is that c0 are the roots of that polynomial. The "Roots" variable above represents the values of c0 as an array of arrays, where each inner array contains the real and imaginary part of cn. So [[0,1],[1,0],[0,-1],[-1,0]] represents the polynomial (z-i)(z-1)(z+i)(z+1). The value of Roots is sent to eval, so you can include javascript code there to generate your roots for you if you want.
Thanks go to Simon Tatham for introducing me to these fractals.

About variables
Variables in Axure RP are structures used to store alphanumeric information (the variable's "value"). Variable values can then be used in a variety of ways—displayed or manipulated using actions. Variables must be named, and can optionally be given default starting values.
Variables in this library
Elements of a widget library need to work unrelated to any document, therefore local variables are used. They are "built-in" to the widgets, mostly using a dedicated text element when storing a value is required to complete various actions.
Editing components
Any element that has a name that starts with "var" (e.g. varSelected") needs to remain part of the component to maintain the designed behavior.

Role of variables in components:
Count selected items (dropdown, data table)
–
Store variable height of a widget to control moving or resizing other widgets (content switcher, multi line code snippet etc.)
–
Dynamically control positioning of a widget based on a selected item in a repeater data set (select)
–
Control default selection in repeater-based component (select)
