I am working on the Blog article on constructing the natural numbers https://xenaproject.wordpress.com/2017/10/31/building-the-non-negative-integers-from-scratch/
Now I am stuck in one proof:
theorem one_add_eq_succ (n : xnat) : one + n = succ n := begin rewrite one, induction n with t Ht, { rewrite add_zero, }, { rewrite add, sorry, } end
I think this scan be solved via succ.inj, but I do not know how to apply this here.
injection
is the tactic version of apply succ.inj
or cases
in some cases
apply succ.inj
turns ⊢ succ (succ zero + t) = succ (succ t)
goal into ⊢ succ (succ (succ zero + t)) = succ (succ (succ t))
so it does the inverse of what I want to do.
How can I apply the injection tactic here?
oh, you want congr
then
if you have h : succ a = succ b
in the context, injection h
will turn it into a = b
but if succ a = succ b
is the goal, then you don't need injectivity, that's just functions respecting equality which is congr
After rewrite add
you can use the inductive hypothesis Ht
-- just rewrite Ht
.
PS any feedback welcome. Over the summer I fully intend to expand that stuff into a more coherent and far-reaching tutorial for mathematicians, covering the naturals, the complexes, and various other ideas I have lying around.
That should have been obvious...
The Tutorial for the natural numbers is great, but as there are no solutions to the exercise I have to ask many questions.
That's how all of us have learnt Lean
Except for some magic wizards, who read the source code
@Lukas I wrote that tutorial and I had no solutions to the exercises either ;-) Some students at Imperial College sent me solutions and I did dump them somewhere on the internet...perhaps in the Xena project github repository (a.k.a. pile of random Lean files which I and some students wrote when we were all complete beginners 18 months ago).
I just came across another problem. I defined the predicate for even like this:
definition even: xnat → Prop | zero := true | (succ m) := ¬ (even m)
but I can not figure out a way to test this #check even one
does only show the Type prop but not the value. #reduce even zero
leads as expected to true, but #reduce even one
leads true → false
which is false, but this becomes quickly unreadable as #reduce even two
is (true → false) → false
.
I think I would be tempted to define beven
here, a function from xnat
to bool
, which is defined in Lean as {ff,tt}
, and use bnot
instead of not
. Then you can define even
to mean beven n = tt
PS you might have more luck with #eval
than #reduce
?
The definition as function from xnat
to Prop
is taken from the blog article. With bool, bnot the definition works. Now my implementation look like this:
definition beven: xnat → bool | zero := tt | (succ m) := bnot (beven m) definition even (m: xnat): Prop := beven m = tt
#reduce zero
no gives me tt = tt
and #reduce one
gives tt = ff
.
I am not yet clear if this is what I should expect. And why is the version returning a Prop better than to bool version?
I guess the author of the blog article was quite incompetent at that time.
To a mathematician, Prop
and bool
are difficult to tell apart. In Lean the key difference between them is that they sit in different places in the hierarchy. bool
is a type, and Prop
is a universe.
So in type theory, Prop
is somehow a lot bigger than bool
.
In type theory, there are universes, and then types in those universe, and then terms in those types. I say "in" because that's how I think of it, I guess type theorist would say "t has type T and T has type u" or something
Because they're quite different in the type theory world, they behave quite differently.
Both both definitions "work" and "give the right answer". I guess the big question is what you want to do with the definitions.
Let's stick with the Prop
version for now, if the prestigious blog writer thinks that this is a good idea.
</sarcasm>
You can still try and prove that 2 is even
You've got to prove not not true
and that should be OK, because P implies not not P
and I can prove true
, because that just means constructing a term of type true
and I can look at the definition of true
to find out what that term is called. Just write #check true
and then right click on true
and peek at the definition.
eew that is a rubbish name
that is a really confusing name
I think there's a tactic which proves true, called trivial
or something
(deleted)
@Lukas your interest made me go back to that blog post and think about how I would have done it nowadays. I didn't think about even/odd but I did think about inequalities. Those 4 inequalities at the bottom were terrifically difficult. I didn't really know what I was doing at the time. I just tried various versions of le and lt, and I think that actually this is the best:
def le (a b : xnat) : Prop := ∃ c, a + c = b
Using this definition of le
, it is not too hard to prove le
versions of all the inequalities. And conversely, this one was by far the hardest to use:
inductive le : xnat → xnat → Prop | refl (a : xnat) : le a a | succ (a b : xnat) : le a b → le a (succ b)
Even proving a <= b implies succ a <= succ b was horrible with this; in the end I proved that this inductive le was the same as the easier-to-use le.
Another thing I noticed was that manipulating xnat is far more tedious than manipulating nat, because you constantly want stuff which is true but which I didn't prove -- stuff like succ a = succ b -> a = b, or a + b = a -> b = 0; the proofs are all easy, but they are not there.
I distinctly remember in 2017 firmly believing that every question about le on nat should almost by definition be completely trivial, because how can there even be any content?
 Pretty short, but it took me a while to work it out. I also used pred
open nat namespace xnat inductive le (a : ℕ) : ℕ → Prop | refl : le a | succ : ∀ b, le b → le (succ b) infix ` ≤' `: 50 := le lemma le_succ (a : ℕ) : a ≤' succ a := le.succ _ (le.refl _) lemma le_of_succ_le {a b : ℕ} (ha : succ a ≤' b) : a ≤' b := le.rec_on ha (le_succ _) (λ _ _, le.succ _) lemma succ_le_succ {a b : ℕ} (h : succ a ≤' succ b) : a ≤' b := show a ≤' pred (succ b), from le.rec_on h (le.refl _) (λ _ h _, le_of_succ_le h) lemma le_trans {a b c : ℕ} (hab : a ≤' b) (hbc : b ≤' c) : a ≤' c := le.rec_on hbc hab (λ _ _, le.succ _)
Nice!
This does illustrate a difficulty with inductive predicates. They're hard to use when not applied directly to local constants.
When you induct you want the fact that succ b
has something to do with b
, but the computed motives rarely give you that.
If I was recursing on equality, it would be completely obvious to do something like the method I chose. Interesting how my intuition for the equality recursor is so much better than other predicates, yet they're not that different.
This has changed the way I think about induction.
It was my job as your M1F teacher to teach you induction, I'm glad you now understand it better than me ;-)
After my M1F induction lecture last year, someone came up to me at the end of the lecture and complained that they thought they understood induction when they came into the lecture but now they realised they were completely confused about it ;-)
It's so obvious now I think about it. If i had succ a = succ b
, it's obviously completely useless to try and recurse on that until I have a succ b
in my goal. same applies here.
What confused them was that I told them that proofs were finite in length by definition but if you think about the proof of P(100) which you get by induction, it looks like "P(0) is true, therefore P(1) is true, therefore P(2) is true...therefore P(100) is true", so maybe "forall n, P(n)" has infinite length and can't be a proof?
I guess it does without the axiom of infinity.
If you don't say induction is an axiom and instead give that as the explanation, then it is an infinite length proof.
This was in my introduction to proof lectures -- I guess you can feel like induction is obvious, and then you start thinking about it that way and then you realise that actually there's more to it than meets the eye.
There's a lot to it. Have you ever tried to prove eq_of_heq
in term mode from axioms? It's really hard.
I have never tried doing anything with heq
, mostly because I remember you going through a period several months ago where you were continually moaning about it!
@Kevin Buzzard
That definition you gave
def le (a b : xnat) : Prop := ∃ c, a + c = b
Is the exact one used in Logic and Proof, chapter 17/18 i believe
I think that the inductive predicate is used in Lean 3 and the definition by cases is used in Lean 4
So it seems that Lean 4 defines the order and decidable equality on Nat
via maps to Bool
, but reverts to using the same kind of framework as Lean 3 for Int
, list Nat
and so on. Does anyone know why that is?
@Neil Strickland My best guess is that derived Bool equality hasn't been built into inductive types yet. It's pretty ubiquitous, so I'm pretty sure it will be built in eventually.

When pagination is enabled, the data is displayed in pages that can be browsed using the built in pagination selector.
Documentation for the pagination feature is provided in the api documentation, in particular:
If you wanted server based pagination, you could look at the external pagination tutorial or consider using infinite scroll, which also retrieves data in pages from the server.
For better performance with the following example, you can choose to load the ui-grid.core.js and specific feature files instead:
<script src="/release/ui-grid.core.min.js"></script> <script src="/release/ui-grid.pagination.min.js"></script>


This project creates an empty but fully configured freeform project with
most of the same capabilities as a regular Java project. For example, you
can compile and run the project or individual classes with a main
method,
compile and run JUnit tests individually or together, build Javadoc, debug the project
or JUnit tests (including Run > Apply Code Changes!), and run the NetBeans
Profiler on your code. In addition, you can add this project as a subproject of any
regular Java project and have everything work as expected.
Unlike a regular Java project, the Properties dialog is the same as for any
freeform project, i.e. it only describes how the project works. If you wish
to customize the behavior of any targets, you may simply edit the Ant scripts, or
edit configuration in build.properties
. There is not currently any way
to get a Properties dialog that works like that for a regular Java project:
This template is also a great way to understand how to make customizations to your own
existing freeform project to support various actions. To explore the implementation, look
in project.xml
for IDE bindings; build.properties
for configuration;
build.xml
for basic targets; file-targets.xml
for targets which
apply to a specific file selection rather than the whole project; and netbeans-targets.xml
for special targets which can only be run inside the NetBeans IDE and serve to integrate Ant
functionality with the rest of the IDE.

Calculation of the mean convective heat transfer coefficient
kc for a laminar fluid flow through an even gap at
different fluid flow and heat transfer situations.
Functions kc_evenGapLaminar and
kc_evenGapLaminar_KC
There are basically three differences:
- The function kc_evenGapLaminar is using
kc_evenGapLaminar_KC but offers additional output
variables like e.g. Reynolds number or Nusselt number and failure
status (an output of 1 means that the function is
not valid for the inputs).
- Generally the function kc_evenGapLaminar_KC is
numerically best used for the calculation of the mean convective
heat transfer coefficient kc at known mass flow
rate.
- You can perform an inverse calculation from
kc_evenGapLaminar_KC, where an unknown mass flow
rate is calculated out of a given mean convective heat transfer
coefficient kc
Restriction
- laminar regime (Reynolds number ≤ 2200)
- developed fluid flow
- heat transfer from one side of the gap
(target=Modelica.Fluid.Dissipation.Utilities.Types.kc_evenGap.DevOne)
- heat transfer from both sides of the gap
(target=Modelica.Fluid.Dissipation.Utilities.Types.kc_evenGap.DevBoth)
- undeveloped fluid flow
- heat transfer from one side of the gap
(target=Modelica.Fluid.Dissipation.Utilities.Types.kc_evenGap.UndevOne)
- Prandtl number 0.1 ≤ Pr ≤ 10
- heat transfer from both sides of the gap
(target=Modelica.Fluid.Dissipation.Utilities.Types.kc_evenGap.UndevBoth)
- Prandtl number 0.1 ≤ Pr ≤ 1000
Geometry
Calculation
The mean convective heat transfer coefficient
kc for an even gap is calculated through the
corresponding Nusselt number Nu_lam according to
[VDI 2002, p. Gb 7, eq. 43] :
Nu_lam = [(Nu_1)^3 + (Nu_2)^3 + (Nu_3)^3]^(1/3)
with the corresponding mean convective heat transfer coefficient
kc :
kc = Nu_lam * lambda / d_hyd
with
| cp |
as specific heat capacity at constant pressure [J/(kg.K)], |
| d_hyd = 2*s |
as hydraulic diameter of gap [m], |
| eta |
as dynamic viscosity of fluid [Pa.s], |
| h |
as height of cross sectional area in gap [m], |
| kc |
as mean convective heat transfer coefficient [W/(m2.K)], |
| lambda |
as heat conductivity of fluid [W/(m.K)], |
| L |
as overflowed length of gap (normal to cross sectional area)
[m] , |
| Nu_lam |
as mean Nusselt number [-], |
| Pr = eta*cp/lambda |
as Prandtl number [-], |
| rho |
as fluid density [kg/m3], |
| s |
as distance between parallel plates of cross sectional area
[m], |
| Re = rho*v*d_hyd/eta |
as Reynolds number [-], |
| v |
as mean velocity in gap [m/s]. |
The summands for the mean Nusselt number Nu_lam
at a chosen fluid flow and heat transfer situation are calculated
as follows:
- developed fluid flow
- heat transfer from one side of the gap (target=1)
- Nu_1 = 4.861
- Nu_2 = 1.841*(Re*Pr*d_hyd/L)^(1/3)
- Nu_3 = 0
- heat transfer from both sides of the gap (target=2)
- Nu_1 = 7.541
- Nu_2 = 1.841*(Re*Pr*d_hyd/L)^(1/3)
- Nu_3 = 0
- undeveloped fluid flow
- heat transfer from one side of the gap (target=3)
- Nu_1 = 4.861
- Nu_2 = 1.841*(Re*Pr*d_hyd/L)^(1/3)
- Nu_3 = [2/(1+22*Pr)]^(1/6)*(Re*Pr*d_hyd/L)^(1/2)
- heat transfer from both sides of the gap (target=4)
- Nu_1 = 7.541
- Nu_2 = 1.841*(Re*Pr*d_hyd/L)^(1/3)
- Nu_3 = [2/(1+22*Pr)]^(1/6)*(Re*Pr*d_hyd/L)^(1/2)
Note that the fluid properties shall be calculated with an
arithmetic mean temperature out of the fluid flow temperatures at
the entrance and the exit of the gap.
Verification
The mean Nusselt number Nu_lam representing the
mean convective heat transfer coefficient kc in
dependence of the chosen fluid flow and heat transfer situations
(targets) is shown in the figure below.

Disease Outbreak Reported
The Centers for Disease Control and Prevention (CDC) have reported preliminary findings of 37 cases of acute febrile illness. Symptoms include high fever, chills, headache and myalgia. Twelve cases have been hospitalized and specimens from 2 of these have tested positive for leptospirosis.
The cases were in a group of 155 United States-based athletes who participated in the Eco-Challenge Sabah 2000 Expedition Race held during 20 August to 3 September in Sarawak, Malaysia. Also participating were 39 four-person teams from more than 20 other countries.
CDC has issued an advisory about the suspected leptospirosis outbreak associated with this event to alert United States-based participants and health care workers. WHO is working with the relevant national authorities to notify the other participants.
For more information, see the CDC web site.


--- creation_epoch:<PHONE_NUMBER> lastmod_epoch:<PHONE_NUMBER> categories: Programming title: Windows Batch Script - Parsing Time Into Components (Hour, Minute, Second) --- I found a U.S. locale specific way to parse a time into components inside a Windows batch script (.bat or .cmd).
@REM Valid only for U.S. (English) locale
FOR /F "tokens=1-3 delims=:." %%i IN ('echo %time: =0%') DO SET HOUR=%%i& SET MINUTE=%%j& SET SECOND=%%k
Note that the %time% variable has the leading space (if any, exists when hour < 10) converted to a leading 0.
Again it only works for the U.S. locale (and similiar). If you need something that works regardless of locale there are other examples that do it in a batch script, but you should really consider an external .com or .exe that inserts it into your batch script (Google it) or use a Windows Scripting Host script instead.

Met Office has its say on chances of more snow for Devon and Cornwall
The latest weather forecast is in
by Jamie HawkinsThe Met Office has had its say on the chances of more snow falling across the south west following heavy showers.
Dartmoor, Exmoor and Okehampton were all hit by heavy snow earlier this week, with at least two inches falling in some places.
It led to disruption on major roads across the region, with several accidents reported.
Stunning pictures taken on Thursday morning show snow settled on Dartmoor with further wintry showers expected falling later on.
However, most of the snow has since melted, with the Met Office playing down any further snow for the next few days.
Press officer Oli Claydon told Devon Live: "It doesn't look like there will be anymore snow for the south west for the foreseeable future.
"Any snow on Dartmoor looks to be disappearing throughout Friday, leaving much drier conditions.
"It is looking much drier generally for the weekend, but there are a band of persistent rain showers moving in from Ireland to the tip of Cornwall.
"Dartmoor and Devon overall is looking dry, if not slightly drizzly.
"It will be Brighter Saturday afternoon and into Sunday and Monday.
"But Tuesday afternoon is looking wet."
Temperatures have plummeted across the country this week, with overnight frosts, but it will be getting slightly milder.
Oli added: "We are looking at highs of 9C on Saturday, potentially 10C in Camborne.
"Overnight tonight we are looking at 6C in Plymouth Plymouth but it could be lower in some parts."
So it's bad news for those hoping to see some wintry showers this weekend.
"Unless you're on the high moors of Scotland," Oli added.
Latest Met Office regional forecast:
Today:
A cloudy start to the day with some brighter spells later where the cloud breaks. For many it will be a dry day with showers likely to affect western Cornwall. A windy day and feeling cold in the breeze. Maximum temperature 9 °C.
Tonight:
Largely dry with clear spells through the evening. Cloud will become thicker as rain arrives to most parts overnight. Slightly less cold under cloudy skies. Minimum temperature 4 °C.
Saturday:
A mostly dry day although some rain lingering around western Cornwall. After a cloudy start it will become brighter with good spells of sunshine. Winds will be lighter than Saturday. Maximum temperature 9 °C.
Outlook for Sunday to Tuesday:
A bright day Sunday and staying largely dry. Dry on Monday too but with the odd morning shower possible and sunny spells. A cold, frosty start Tuesday with rain later.

Here's the Terminator: Resistance launch trailer
by Shaun PrescottTo coincide with the launch of Terminator: Resistance on Steam, here's the shooter's launch trailer. It's now available here, but the trailer above lets us enjoy some delicately edited together footage of robots absolutely copping it.
Developed by Reef Entertainment, Terminator: Resistance is set 31 years after Judgement Day, in 2028 to be precise. The action plays out in Los Angeles, where the war against the machines is well underway, though all reports suggest that it's far from a run-and-gunner: careful planning and stealth seem to factor in heavily, perhaps in a way reminiscent of the recent Wolfenstein games.
If the footage above piques your interest, maybe you should check out this 10 minute gameplay video. It actually looks quite promising, and if there's one thing the 2019 desperately needs, it's a good single-player first-person shooter.
Correction: This story initially reported a December release date for Terminator: Resistance.


(seen at the Portland International Film Festival)
FILM TITLE: The Children of Chabannes SUPER FEATURES: Magnificent story of one of many heroic stands during WW2 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
While this is not a feature film at all, and showing in a Foreign Film Festival, there is one ting that this has going for it, that is subtle, imaginative and totally engrossing. The compelling beauty in this film is really the same survival instinct that has spawned so many other film directors and creative artists, whose lives had been affected and destroyed, during WW2. One might mention right off the blocks the likes of Andres Wajda, or Roman Polanski, or Volker Schlondorf, and many others, but comparing their emotional work, to this film, is something that is difficult to bypass, and leave alone. This fine documentary film, even though it has personal connections for Director Lisa Gossels, is a whole lot more.
There is not much to say about Chabannes. Like many villages, and many other people whose stories are still untold, both horrific or simply heroic, some not so great, but no less valid in the context of things, this so special of a film, makes a track that is difficult, that is exciting, and almost makes one wonder why is it that many of these are not honored as they should be. Not so much as a group of people that saved many Jewish lives, but also as a group of people that believed in things far larger and wider than simply a who's who of a religious world. Something that is still found today, in so many places.
Chabbannes, was a remote location that had the fortune of having some good teachers and a feisty and energetic school administrator, that had more passion for the same children that he supervised, and did what he could to ensure he could do well for them. And when, in the unoccupied part of France, this deteriorated with decrees that denied Jewish people a part in their daily lives amidst others, this school and many of its teachers, some of whom could have easily snitched, did more in the way of helping a lot of children, be they Jewish or not, that is still remembered fondly, and deservedly so, today. Films like this, do the one thing that allows this to be stapled as one of the many monumental events. Saving 400 refugee children may not have sounded like many, but considering the odds and the political climate, it is a massive undertaking, that constitutes fortitude, heart, no sleep, love, and above all an astuteness of personality that must always be a step ahead of the pursuers and those in charge of making sure these things do not happen, as did a befuddled Chief of Police, who from his quotes, must have known what is going on.
Of special attention in this well written and directed film, with magnificent continuity, is the lively interviews with three or four of its instructors who were alive at the time, and still are today. Their energy and desire to do something more, was not what they were after. It was their dedication to the children alone, Jewish or not, that shows up immediately, and one can easily reminisce our own school days, today, to notice that there were a lot of instructors that have never had an inch of heart anywhere near these. The athletics instructor that made sure they all had strength where others will not. The other instructor that told them all that the cold could not beat them to win, and the other teachers that made sure that many of these boys and girls survived, against horrible odds, in a country where their livelihoods and rights had been revoked for political reasons and gains.
If there is a bit of a sad thing in this film for this reviewer, it is a personal one. I was born in 1950 in Portugal, and these kinds of films were ingrained in our minds as youngsters, and we were pretty much told a fairly good sense of right and wrong. It helped that my own father was becoming a well known name in Portuguese literature along the way, and his armada, was not exactly Jewish children, but the arts, movies, paintings, the music, that has marked the 20th century. By the time I was 10 and we had moved to brazil, we had already met, house, and fostered friends and other teachers and professors that had many connections to many events in Europe, some in various concentration camps, some involved in other resistances, and some that simply hid for a long time, and fought their own war. Their stories, like this one at Chabannes, still remains vivid in my heart and mind, and still the most scary part for me to tackle. It is not a fear, it is not a love, it is not a life. It is something that people raised under the mantle of a Walt Disney, and a yellow brick road, have a hard time understanding, or really having much compassion for. Their guilt is only measured in the acceptance of a Spielberg film or two, not in the people around them. I have found that day in and out, many of the people around me, are far too distant to have any sort of direct knowledge (and mine is indirect) about these things and what they constitute to one's life. Vietnam came close, but the denial of what happened then, or understanding of what it has done for many lives, is not any different for me.  Quake and Doom and Half-Life still rule. I, personally, have never enjoyed that attitude, since my own family was involved in the war in these endeavors, still unspoken to this day, while they were under a Fascist government not unlike the one in Spain. And I still do not know what it is they did ... probably never will.
It is wonderful to see that there are believers in the true human spirit, that knows and understands that war is sick, and that people make a difference.  I imagine this to be a fault in the internal constitution that has room for a God in a book, but no action in one's heart. If anything, the thrust of this film, which can hardly be measured in the scale of human dignity -- the one that is least discussed -- is that the future is always in our hands, and that those who are most innocent are the ones that will need it, and will have to live in it.
Magnificent film, about something that many of us will never experience, or fully understand. Well done, Lisa Gossels.

This dialog is used to enter the key for the following symmetric encryption algorithms (classic and modern):
Text input:
Vigenère
Hex input:
Byte Addition
Binary Exclusive-OR (XOR)
IDEA
RC2
RC4
DES (ECB)
DES (CBC)
Triple-DES (ECB)
Triple-DES (CBC)
Rijndael
MARS
RC6
Serpent
Twofish
After you have entered the key, you can encrypt the document by clicking on the Encrypt button or pressing the RETURN key. If you wish to decrypt the document with the entered key, choose the Decrypt button.
A key that is already stored in the internal key store could be inserted directly by clicking the button "paste key" (if there is no key stored for this encryption algorithm, the button is deactivated and appears in gray).
Most of the symmetric procedures (IDEA, DES, MARS, RC6, Rijndael, Serpent, Twofish) require a fixed key length. Shorter keys are padded with zeros.
Example 1: Entering hex characters with DES (ECB).
As DES key you choose 12 AB (which is 16 bit):
The current file is encrypted with the DES key 12 AB 00 00 00 00 00 00 (according to the set key length the DES algorithm is expecting a key comprising 64 bits and the default value to hex keys is 0).
Typical key lengths and their presentations are listed in the table
Key presentation.
The hex strings (128 and 192 bit) entered for the Triple DES and DESX variants are internally considered as a sequence of 2 or 3 different shorter keys used in the different algorithm parts.
Example 2: Entering text characters with Vigenère.
As Vigenère key you choose TESTER.
Remark:
A few classic algorithms require different types of key input dialogs e.g.
Hill ,
Playfair, ADFGVX
, Homphone,
Permutation and Solitaire.

It's time. Come one, come all - election nerds, data hounds, open government advocates. Join the growing list of OpenElections volunteers who are helping to capture election results from all 50 states. We're still looking for folks to join the effort, so if you'd like to help out, let us know which state (or states) you would like to work on.
More than one person can work on a state as a metadata gatherer or in actually obtaining and sending us the results data. So, if you are interested in working on a state that has already been adopted, let us know that too.
For each state, we will first inventory the metadata (the data about the data) for statewide and federal races from 2000 onward. This process will identify how election results are archived in each state. We expect formats to run the gamut, from clean, machine-readable CSVs to scanned image PDFs of hand-written results. This process will also give us a snapshot of the elections that took place, including edge-cases such as special elections and recalls.
We plan to initially focus on statewide and federal races rather than local elections. The goal is to document the data about the elections that took place in each state, including details such as tabulation level of results (precinct, legislative district, county, etc). All these details will be entered into a centralized data admin. You can learn more about hunting down and entering data in the admin in the nitty gritty section. Most importantly, we're asking volunteers to not just snag data from election agency websites, but to call agency officials to identify the best possible data source.
All of this hard work will get us to the moment of truth - how big a task have we actually set ourselves?
After the metadata is entered into our admin, we'll devise a strategy to gather results from all states and make them available to the public. Volunteers will assess the data formats for their state(s) and then get the data into our project Dropbox. The work of processing of all of this data will be done by the OpenElections team, but once we have assessed the best strategy for standardizing it, there may be some work to be done here too for more technical volunteers. But, for now, the big push is to get going on the metadata.
If you'd like to join our effort to increase transparency of the democratic process in the US, please contact us at<EMAIL_ADDRESS>and we'll set you up with data admin access so you can start gathering metadata. If you've already signed up, we'll be in touch soon with your login credentials.

The morning session opened with a HUGE elephant under the rug - “Where is Oracle?” There’s no booth in the Pavilion - super strange.
 Jonathan Schwartz, Sun CEO, for all of his ponytail excellence, wasn’t exactly inspiring a great deal of excitement in the crowd. In fact, the loudest applause from the audience was initially for the tech support guy who fixed the projection for one of the demos.
Thankfully things eventually got moving. Verizon and Sun announced a very exciting partnership whereby Verizon will expose their network elements to Java developers. Things like presence, location, friends and family lists, mobile-to-mobile lists - all of these will now be accessible to the developer. These specs will come out on July 27. This announcement is very exciting as it means that Verizon phones will now be a very powerful platform for Java mobile development.
The JavaFX demos were really cool. They demoed one of the new LG XCanvas series of TV’s, which actually run JavaFX on the TV itself. Processors and video codecs actually live within the TV, and the TV is connected to the network. Live, on-demand, interactive content is now available directly on the set, and it’s very smooth. It seems that JavaFX continues to be the center of innovation within Sun. This continued with a demo of the new JavaFX visual authoring tool. This was very impressive. JavaFX apps are now possible with absolutely no coding, which makes them extremely accessible to content designers. Visual assets can be dragged and dropped onto the stage, animation can be built by recording drag motions, no compile-build-deploy cycle. Another great features was visual wiring of component properties to UI controls. Very smooth. And apps can be deployed directly to the Java App Store via the tool.
Funny, this was the big oops of the keynote. Nandini Ramani leaked the “liveness” of the app store before the official announcement. Nandini - “And you can deploy directly to the App Store.” Jonathan - “We haven’t launched the App Store yet.” OOPS.
But the App Store was immediately announced next. http://store.java.com is now in private beta, and I quickly registered and got an invite. I was playing with the App Store in the following session and downloaded two applications. Extremely like the iPhone App Store for Java. You can now distribute your Java applications directly to billions of consumers with Java-enabled devices. At this point it only supports free applications, as they have left it up to the community to provide feedback on how money should be collected. Nice move. Very impressive. This could be a game changer for the Java platform if it’s used correctly.
FINALLY the elephant came out, but it took Scott McNealy coming on stage to get it done. It was very interesting how Jonathan Schwartz unceremoniously left the stage. Scott thanked him twice for his stewardship of the company - it was a very obvious yet implicit changing of the guard. Funny that they should decide to introduce Larry Ellison, CEO Oracle, via a great amount of cheesy images (Java flying on the sail to Larry’s yacht, etc.) At the end, while no promises were made, Larry said that we should look to the past to see what the future will hold and expect more of the same. “I don’t expect any significant changes.” I hope that holds true. The audience very properly gave Scott a standing ovation as he left the stage, a nice gesture to a guy that has continually kept Sun on the cutting edge of technology.
All in all, it was a bittersweet keynote, but I’m cautiously optimistic about the future of the platform. Our landscape is continually changing, and the future is uncertain. If everyone’s being transparent, however, good things are still to come.


§604-6 Ejectment proceedings. Nothing in section 604-5 shall preclude a district court from taking jurisdiction in ejectment proceedings where the title to real estate does not come in question at the trial of the action. If the defendant is defaulted or if on the trial it is proved that the plaintiff is entitled to the possession of the premises, the court shall give judgment for the plaintiff and shall issue a writ of possession. The rules of court shall govern the stay of a writ of possession. [L 1949, c 315, §1; RL 1955, §216-5; HRS §604-6; am L 1970, c 188, §14; am L 1971, c 144, §2]
Rules of Court
Stay, see DCRCP rule 62.
Case Notes
Plaintiff in ejectment need not show possession within twenty years if plaintiff shows title and no adverse possession is proved. 7 H. 324 (1888).


#include <db.h>int log_put(DB_LOG *logp, DB_LSN *lsn, const DBT *data, u_int32_t flags);
The log_put function appends records to the log. The DB_LSN of the put record is returned in the lsn argument. The flags argument may be set to one of the following values:
The caller is responsible for providing any necessary structure to data. (For example, in a write-ahead logging protocol, the application must understand what part of data is an operation code, what part is redo information, and what part is undo information. In addition, most transaction managers will store in data the DB_LSN of the previous log record for the same transaction, to support chaining back through the transaction's log records during undo.)
The log_put function returns the value of errno on failure, and 0 on success.
The log_put function may fail and return errno for any of the errors specified for the following Berkeley DB and C library functions: abort(3), close(3), dbenv->db_paniccall(3), fcntl(3), fflush(3), fprintf(3), free(3), fsync(3), getenv(3), getpid(3), getuid(3), isdigit(3), lseek(3), malloc(3), memcpy(3), memset(3), open(3), sigfillset(3), sigprocmask(3), snprintf(3), stat(3), strerror(3), strlen(3), time(3), unlink(3), vfprintf(3), vsnprintf(3), and write(3).
In addition, the log_flush function may fail and return errno for the following conditions:
The record to be logged is larger than the maximum log record.

Both the class and id attributes are deceptively simple. They are among the easiest aspects of HTML and CSS to implement, and their self-explanatory names make them approachable to even the most frustrated learner. But they are logically embedded into the structure of HTML as much as any other component, and only a good understanding of this logic behind them will allow for optimal utilization.
To understand classes and ids, you must first picture the Document Object Model. You don't need to know the inner workings of the DOM, but you should understand that every element is an object within the Document Object Model, a node on a tree. More specifically, every element is an HTMLElement object. Think of HTMLElements like people on a family tree, unique individuals, but all connected in a hierarchal fashion.
Every HTMLElement object can have properties. A property like a name. And, for simplicity's sake, HTML attributes are just properties by a different name. They are HTTP attributes that are just repurposed when defined in connection to an HTML object so that they can fit nicely into the property definition.
So ids and classes are properties. But what's the difference then, you ask? As you probably know, and id is unique. It is a key. It is an identifier. It is good practice, and commonly understood, to exist singularly. An object can only have one id and that id only exists for that object. If you read otherwise, read until you fully understand what they're saying, but until then take what I say as truth!
But what about the class? You've read about them. An element can have more then one class. How does they gritty HTMLElement object sort this out differently than it does an id? First off, an HTMLELement actually does not have a property called class, it has one called classList. This is, listen closely now, a read-only list of space separated class names. If you know any basic coding, it is like an array. That is how you can fit so many class names into one property. This is why they can be put on numerous elements. There is room for the infinite in the list. And they are just regular words, not keys.
So from knowing that, you can start developing best practices when it comes to using id and classes. Think about how they fit into the HTMLElement before you start sticking them on everything. This will go a long way towards tackling common sense problems. Like, maybe you're wondering if an element can have a class and an id. What about multiple classes and an id? Of course! Think about it. They exist as different properties. They don't tangle up. The answer reveals itself.
But once you start working them, it's important to realize some things. First, they are namers more than anything else. They don't do anything to your elements by default. They allow you to do things to your elements. So use them when you want better control over your elements. They allow for easier selection.
Second, don't use them just to use them. The thing you learn about CSS is that simplicity makes things easier. Classes and ids make things easier. Using classes and ids simply and only when there is need makes things easier! Too many classes or too many ids makes everything bulky. If want to place the same style across multiple elements, stick it on their class rather than any id. You then only write it out once in your CSS file.
Third, ids actually also allow for some special things, like linking to a particular part of a page via an href attribute. Again, if you think about this, it can only apply to ids. Both ids and classes are namers, and you can't move to multiple places on a page if multiple elements have the same class, so only ids allow for a good standard in giving you want you want.
Fourth, be specific as possibly when naming them. They are namers. They are identifiers. Not descriptors. Think about it.
Last but not least, distinguishing between classes and ids is important when it comes to determining CSS specificity with regard to styling. Simply put, ids are more specific then classes. When marking the styling of an element with a class and an id, the id styling will win out, even if the class styling is further down the CSS page, even if you're specifying by a zillion classes and just one id. So when it comes to styling and you're working with classes and ids, be as specific as it makes sense to be. Utilize the ids if you have them. I like to think of it like this. I style based on classes for the foundation, and the unique alterations for individual elements are made via their ids.

The complete guide to setting up your web series’ webpage, Part 1
Other parts of this series : The Complete Guide to Setting Up Your Webseries Webpage
I’ve seen a fair number of people on Web Series Chat on Twitter and elsewhere asking about setting up a website for your web series - how to do it, what to use, what hosts are good, and so on.
I’ve been making websites - mostly for Web series - for 16 years now. There are a lot of choices and options out there, but if you choose the right ones, 2011 is about the best year yet to quickly set up something powerful, flexible and usable that major corporations would have killed for back in 2002.
So, here we go with a complete guide to setting up a site for a web series as quickly and painlessly as possible. I’ll go through the software and hardware you need to make it work, talk about a couple of common customisations, let you know what you need and don’t need, and discuss the goals of the entire thing in the first place!
Oh, one thing. I said that the site would be quick and painless - I didn’t mention cost. From my experience, you’re far better NOT trying to minimise your costs below a certain level. You can produce a surprisingly sophisticated website for a sum which a lot of people would consider ridiculously small, but there comes a point where trying to make your site for free will really hurt in the long term. I’ve tried both ways.
Goals for a site
So what does your site need to do?
One of the things that makes almost any website, and particularly a show site, tricky to design is that it’s actually for two audiences: returning viewers who want to find the new content quickly, and new visitors who want to find out what the show’s about.
I’ve written about taking cues for web design from other industries before, so I’m not going to go into the design of the thing here to any great degree. However, one of the most common mistakes that even experienced Web businesses make is to start designing before you’ve figured out what your design’s supposed to do.
So - what you need your design to do is two-fold. For new visitors, it needs to:
Tell them what the show is and why they might want to watch it - either with words or pictures. Importantly, you’re not aiming to sell the show to everyone here - instead, you want your target market to find out that this is the show for them as fast and convincingly as possible. If a visitor isn’t in the target market, you don’t really care about their reaction.
Direct them to watch the show in the order that will make the best sense, with as little effort and confusion on their part as possible. That might be most recent episode first, or it might be first episode first, or it might not matter.
If they enjoyed your show, persuade them to sign up to some form of subscription or other ongoing contact with your show as effectively as possible.
Meanwhile, for existing visitors, it needs to:
Promote your new content so that they can easily find it
Allow them to navigate through old content easily and logically.
Your website PROBABLY (but not definitely) also needs to:
Help and encourage viewers to share your content and tell their friends, enemies, and Facebook readers about it.
Make it easy and fun for your viewers to interact with you and each other, comment on the show, and generally become more involved.
Make the site easily visible to search engines so that they can drive new traffic to your show.
(Probably? Yes. You can run a show that doesn’t do these things - but that’s a subject for another article.)
So, now we know what we need to do, we can design a site appropriately!
What you don’t need for your site
The Web development world has really matured over the last few years, and a lot of things that used to be the case if you wanted a sophisticated website no longer are.
In particular, blogging platforms and CMS (Content Management Systems) have advanced leaps and bounds. That means that there’s one huge thing that you absolutely don’t need any more to set a site up from scratch:
You don’t need a programmer
I coded the CMS for every series I’ve worked on, from Matrix 4x1 through BloodSpell through to Kamikaze Cookery. Nowadays, unless I was doing something very specific, I wouldn’t bother.
The Wordpress blogging engine has advanced until it dominates the Internet and provides a solid platform to build 90% of content-centered websites on. There are thousands of plugins to do almost anything you want (and remove some of its more well-known limitations) and highly customisable “themes” that means the amount of HTML and CSS you need to write is minimal.
You still need to be comfortable with computers - your aged relative who tries to use a mouse as a foot pedal still couldn’t do the site setup for you - but you no longer need to be a coder, really, to set up your Web presence.
(Death Knight Love Story’s website is hand-coded rather than using Wordpress. I’m doing something very specific with that site and whilst I theoretically could use a CMS like Wordpress, I have some rather specific and unusual requirements for the site.
If you have the skills to write code or design a website in a very non-standard way, it’s still useful. However, if you’re not setting up with the realistic expectation of tens of millions of visitors, you don’t need to do the kind of hard-coding I’m doing there.)
Other things you don’t need:
You don’t need a super-expensive hosting package. It won’t hurt, but the cheapest web hosting setup from a reputable host should be able to handle a pretty solid amount of traffic, enough to cope with a mention in a major news outlet or similar.
You don’t need “one-click” Wordpress installation. Various hosting providers offer it, and I initially assumed you’d need it when I researched this article, but in actual fact the Wordpress installation is simple enough that anyone can do it on virtually any platform.
You don’t need to install a lot of WordPress plugins. In fact, I’d heartily recommend you avoid doing so. Wordpress plugins can easily make a site much, much slower to load - I can’t count the number of times I’ve traced a speed problem on a WP site to a single rogue plugin calling something huge from an overstretched remote address. In particular, I’d suggest you avoid the Facebook Like plugin unless you really have to - it kinda sucks.
You don’t need to be able to use Linux. The Web hosts I recommend will all be running your webspace on Linux, rather than Windows or Mac OS X, and that might sound pretty scary. However, unless you want to get into the nitty-gritty of server administration, you can rely on your webhost for pretty much anything Linuxey - indeed, a lot of hosts would prefer you did. (Sometimes my long-suffering webhosts, the astonishingly cool Bytemark would probably prefer I did too, but hey, they foolishly sold me a dedicated server…)
What you need for your site
For the installation I’m going to suggest, you need a Web server, a mailing list server, an installation of Wordpress, a bunch of plugins to fix problems, and that’s about it.
Engine: Wordpress: The old-school approach to a website was to code everything up in raw HTML - the markup language of the Web. Sites designed like that were difficult to update, and didn’t offer any kind of interaction - even commenting. From our “goals” point of view, a raw HTML site requires a lot of work to fulfil any of them.
That’s why these days most sites are built on a coded Content Management System, or CMS. Using a CMS, you can add whatever you like - text blogs, videos, etc - and the server will convert that into HTML for other web users to view. If you change something, it’ll change it across all pages. And, of course, it means that other people can add content too - like comments!
There are a lot of CMSes out there, and they all have their rabid fans, but realistically for a non-technical setup, and one that isn’t going to take too much time, Wordpress is by far your best alternative. It’s sensationally easy to get going - they tout a “5-minute installation”, and in terms of hands-on time, it’s probably less - even for a non-technical user. You download the Wordpress program, use SFTP to send it to your host (sounds complicated, but it’s basically drag-and-drop like moving files in Explorer or Finder), use your web host’s interface to set up a database (again, sounds scary, but all you’ll have to do is choose a name, username and password for the database and it’ll be done automatically), fill in the fields you just chose on another web form, change a couple of “permissions” via SFTP (by clicking some clickyboxes) and bam - working Wordpress.
Wordpress is also very customisable, and even better, has an awful lot of people doing the customisation for you. It’s been developed for 5 or 6 years in a real-world, big-companies-and-sites-actually-using-it environment, so its design is very well-focussed on what you’ll actually want and need, and it’s very simple to use. It’s also free and Open-Source, which is a bloody good start.
Wordpress is intended as a blogging platform, but a blogging platform has most of the same features you’ll need for your web series. It’s focussed toward getting people to subscribe, having an easily navigable archive of content, and allowing people to interact with you after viewing your content - in other words, it meets most of our goals out of the box. You’ll be embedding video rather than writing text, but other than that, what you’re doing as a Web Series creator is almost exactly what it’s designed for.
Other CMSes like Drupal are harder to configure and have less available options. They’re powerful and they have their fans, but all else being equal, avoid.
Of course, as a final option, you could create the site from scratch using pure HTML (web markup) or write your own CMS. Even if you have the skills to do this, I wouldn’t advise it. I’ve done both and I’d advise you to avoid both unless you have a very specific reason you want to do that. Pure HTML sites are a pain to update and have limited interactivity, and it’ll take a LONG time to code something with the same level of functionality as Wordpress - I know, I’ve tried.
Subscription Engine: Mailchimp or Feedburner As per our goals, you’ll want something to alert your viewers when a new episode comes out, and you want as many as possible of them to subscribe to it. There are basically two options here: either RSS or an email list.
In “Get Crazed Stalkers”, I advise you to use an email list if at all possible. That’s because nearly a decade of research suggests that the response rate to email is far, far, far higher than it is to an RSS feed, Twitter, Facebook, or anything else. Email is a “push” medium - your reminder about the latest episode turns up in your viewers’ inbox without them having to take any action, as opposed to RSS, where they’ll have to remember to check their reader and actually click on your feed, or even worse Twitter, where you’re chancing they’ll see your message before it gets buried by some crap from Charlie Sheen or Stephen Fry’s latest news about his sandwich.
Don’t get me wrong - you should probably use Twitter too. But for notifying your loyal followers that Something Awesome This Way Comes (your new episode), you probably want to use an email list.
I’ve tried a few different email list providers, and the one I’m most impressed with is Mailchimp - it’s free for lists of under 2,000 people (which will include yours, in all probability), it’s very powerful, it tries very hard to be user-friendly (arguably a bit too hard - I get fed up with their design interface - but there’s loads of help available too) and it handles all the gubbins of getting double-opt-ins and so on without you having to faff around with it.
If you’re not comfortable with an email list or think that your audience would prefer RSS (or are just feeling a bit lazy), you’ll want to run your RSS feed through Feedburner. It’s a startup that was bought by Google, and aims to give you some kind of data and intelligence on how your feed’s doing. Most simply and notably, it’ll tell you roughly how many people are subscribed to your feed, and also it will tell Google Analytics how many of them clicked on your latest episode. Analytics and the ability to tell what’s actually happening are vital - grab it.
Hosting Provider - Dreamhost or NearlyFreeSpeech.net Oh, god, the eternal “where should we host this?” question. Sadly, it appears from some reading around that whilst I personally haven’t had any hosting problems in years (the years I’ve been with my current host - Not A Coincidence), the endless hassles of bad, absent, permanently down or clueless webhosting are still very much with us.
Fortunately, there are some superb hosts out there. The very best of the best aren’t really accessible to anyone without hardcore knowledge - much as I’d like to recommend Bytemark, Slicehost, or even Amazon EC2, they’re overkill for a web series and not usable if you’re not competent with Linux server administration. (If you ARE - Bytemark in the UK or Slicehost in the US, done, that’s it, move along.)
The collective brains of Reddit and Hacker News, two of the most knowledgable and largest communities on the ‘net, mention a lot of lower-end hosts, but two names keep cropping up: Dreamhost and NearlyFreeSpeech.net. I’ve also used both, and I can attest that they’re excellent.
NearlyFreeSpeech.net are, as the name suggests, also very very cheap. They charge $.03 per day for basic services like a database and Web availability, and beyond that only charge for bandwidth and disk space used. $1 gets you 100 Mb storage space a month, which is probably a lot more than you’ll need. Meanwhile, bandwidth costs a dollar per gigabyte used. To give you an idea of how far that goes - the BloodSpell site serves up about 100k of data for each page view. Assuming two page views per visitor and 5,000 visitors per month (approximately 1k per episode if you’re releasing weekly), that’d mean you would end up paying… $1 per month for bandwidth. Ten times as much and you’ll pay $10 per month.
Obviously, if you have a large traffic spike, you’ll pay a bit more - but there are very few sites on the internet, speaking from personal experience, that will drive more than 20k visitors to your site, meaning an additional $4 charge or so.
NearlyFreeSpeech have an excellent reputation in almost all other areas. They have been around for nearly a decade, and have a large and loyal following. They’re unusually stable for a shared hosting service - you’ll probably not see much downtime if any. And everything they offer is extremely technically solid.
Their only downside is that they’re not the friendliest of outfits. They pitch themselves at the slightly more expert user, and there are quite a few reports of unfriendly customer service, particularly to somewhat less technically-inclined customers. As one user online said, “if their support tells you what is wrong and you don’t understand what they are saying, it is up to you to go research what the terminology means and do your level best to figure it out”.
If you’re looking for great customer service or you’re worried that your bandwidth bills will mount up, you might want to consider Dreamhost instead.
Like NFS.net, Dreamhost have been around for forever and a week. I used them back in 2006 and they weren’t newbies then. Their selling feature has long been a promise of “unlimited” bandwidth - which, I’d have to say, was in my experience fairly accurate. I was using them to host video files, and probably transferred terabytes of data from them - without a peep of complaint. A lot of web hosts claim unlimited bandwidth but don’t deliver - Dreamhost will, in all likelihood, provide you with more bandwidth than you can use.
They also pride themselves on user-friendliness, and are very well-set-up to assist less technically able users. I’ve personally had excellent technical support interactions with them, including a billing dispute that they refunded without any problems. They also operate a number of “one-click install” systems - I’ve not tried them, and as mentioned above, you don’t need them, but the ease-of-use of installing Wordpress with a single click is a pretty cool feature.
Downsides? Well, they’re not super-cheap, at around $10 per month. And a lot of users complain about downtime or occasional slow service with their services - I’ve seen a few problems in that direction myself. You’re unlikely to see days of outage, but the occasional couple of hours is a possibility - they certainly have a worse reputation for stability than NearlyFreeSpeech.
It’s also worth noting that there are a lot of negative reviews of them on some websites. Reading between the lines, and looking at the fact that they’re mostly complaining about their sites being taken down, I strongly suspect that many of these disputes were due to the complainers using seriously dubious “black-hat” search engine optimisation techniques, spamming, or other stuff that any host is likely to clamp down on.
In summary - if you’re likely to start small and you’re willing to learn and research a bit, choose NearlyFreeSpeech.net. If you’re wanting to go a bit bigger or want a bit more hand-holding, choose DreamHost.
And if the downsides of both of those are too much, read this thread on Hacker News (although ignore the mentions of app hosts like Linode and Heroku) or this one on Reddit for other options.

The system has two states, heating and cooling, as shown in the figure below. In the heating state, the temperature of the room is increased linearly,
dx/dt = 1
where x
is temperature.
In the cooling state, the temperature is dropped linearly, i.e.
dx/dt = -1
The control rule is that if the temperature reaches 0.2 degree, then switch
the controller to the cooling state; if the temperature decreases to 0 degree
then switch the controller to the heating state.
We use this example to illustrate the accuracy of detecting events, and the
ability to simulate hybrid systems in Ptolemy II. In particular, the
time at which the temperature thresholds are detected is precise,
irrespective of the underlying simulation sample rate.
The simulator will iterate if necessary, and backtrack if necessary,
to accurately determine the time at which events occur.
