About Me
I'm Ivan Dusseau, a third-year college student and robotics enthusiast. I've been coding for a long time, and I needed to touch up on the basics again. Generally, I prefer to dink around with the physical side of web development and machines in general. There's nothing wrong with coding, but I find it frustrating when I can't feel what's wrong.
I was part of a robotics team for four years and had the privilege of participating in the world championship. I had a fantastic time working in a midsize team working towards a common goal. I learned the value of understanding your teammates and choosing the right people for the right jobs.
Please Help Me
The world is a spooky place. There are ghosts and ghouls and goblins this time of year, so it's best to stay inside. Without the comfort of light you can't quite be sure what is out there, waiting in the dark crevices at the edges of the light. Lurking at the edges of your vision, fidgeting where people can't quite see grasp. Generations of humans have known the fear of the dark, known to fear what flees from the fire.
So for generations, humans have flocked to the fire and the light. But never has anyone started to question the light. Perhaps it's better to ask not if the light will keep you safe, and instead question what's lurking in the light.

Load the packages and write the codes as shown below.
That’s all. Pretty easy and straightforward, right?
library(tidyverse)

stat_halfeye(
point_color = NA, .width = 0, height = 0.6,

$res_type
You can create your template for data entry in few easy steps! Select the appearance of your field (text box, dropdown, checkbox), name it and provide a short description.
Start typing the full URI or the prefix (e.g. foaf:depic..
) of the RDF property to be associated to the field.
You will get suggestions from the LOV vocabularies catalogue for autocompletion.
Easy right? You can still choose to ignore suggestions and create your own property.
Field values can be free text, entities, or controlled lists of terms.
Free text
: any free text descriptions. You can use this field value as the main title the record (use the checkbox below).
You must select one field as a title.
Entity
: a term that can be reused in other records. When creating a record, you'll get autocompletion suggestions from Wikidata and the catalogue.
You can select this field to be used as a filter in the page Explore. You can create as many filters as you want.
Location
: a place that can be geolocalised. Similarly to entities, autocompletion suggestions from geonames will appear.
A Textarea allows for longer text descriptions to be annotated.
When filling in, press return to enable entity extraction from text (e.g. people names, places, organizations).
You will be able to accept or reject suggestions, and these will be automatically added to your data (by means of schema:keywords
)
Create your own controlled vocabulary in VALUES
.
For each line include the full URI and the label of a term separated by comma. URIs can be from external vocabularies or reuse the URI base that you setup.

[dscrdvrsc] <Hollowman9000> I thought CMC was a simple application to fill out
[dscrdvrsc] <Hollowman9000> Or are there minimum volumes involved?
[dscrdvrsc] <CryptoAlex> @Hollowman9000 From CMC FAQ
The criteria for a cryptocurrency to be listed is the following:
- Must be a cryptocurrency or a crypto token. (OK)
- Must be on a public exchange with an API that reports the last traded price and the last 24 hour trading volume. (DP is getting there, it seems)
- Must have a non-zero trading volume on at least one supported exchange so a price can be determined. (OK)
- For market cap ranking, an accurate circulating supply figure is required. (OK)
If you'd like to have a cryptocurrency listed and it meets all of the criteria, please fill out the request form.
[dscrdvrsc] <Hollowman9000> I thought it was a minimum of $500k
[dscrdvrsc] <Hollowman9000> Maybe that was adding an exchange to CMC
GatewayBOT28-Aug-18 11:50 PM
[dscrdvrsc] <miketout> Right now, it's a question of being on a supported exchange and getting accepted, as far as I know.

[dscrdvrsc] <miketout> @dukeleto I assume you were posting it because you disagreed with him, but without any commentary from you. am I right?
[dscrdvrsc] <miketout> I see he's taking on all of crypto with blithe tweets that have no substance
GatewayBOT29-Aug-18 04:55 PM
[dscrdvrsc] <wistar> @miketout : Ah, gawd. I actually know Matt Blaze from a long time ago (via his then girlfriend Jutta Degener). I am a little surprised at his broad brush denouncement.(edited)
[dscrdvrsc] <miketout> @wistar I'd be happy to talk to him and help him understand, which would likely require a little more than 280 characters
[dscrdvrsc] <wistar> Well, let me see if I can reach out to him. It has been ... over a decade.
GatewayBOT29-Aug-18 05:13 PM
[dscrdvrsc] <wistar> @miketout: Did you ever know Josh Benaloh of MSR? He and Blaze are crypto colleagues. He might be a better path but I didn't ever know him very well.
https://www.microsoft.com/en-us/research/people/benaloh/(edited)
Josh Benaloh is Senior Cryptographer at Microsoft Research and an elected director of the International Association for Cryptologic Research. …
[dscrdvrsc] <miketout> I didn't know him really, but I believe we met before. He looks like someone we should talk to. Do you know him?
[dscrdvrsc] <wistar> He'd never remember me, but I certainly had meetings with him in attendance in relation to future vision scenarios for craig.(edited)
GatewayBOT29-Aug-18 06:49 PM
[dscrdvrsc] <dukeleto> @miketout mostly looking to just spark discussion. Matt did help design ZeroCoin protocol, which evolved into Zcash protocol that KMD/VRSC/ZEC all have at their core. I agree about "blithe tweets" and also, he has probably earned the right to be blithe. He just ran a voting machine hacking event at DefCon, he is very deep into the now-and-here election technology world, and seems pretty jaded by fancy new technologies like blockchains/etc
[dscrdvrsc] <miketout> i think when you're blasting real tech of real projects, gaining fame and then being blithe about your own failure to do something securely is irresponsible(edited)
[dscrdvrsc] <dukeleto> actually, I confused him with Matt Green from Zerocoin protocol, oops
[dscrdvrsc] <dukeleto> Most likely he is talking about the 999 scammy coins out there that have no tech and are telling people their ICO will solve elections, and has never heard of Verus
[dscrdvrsc] <dukeleto> Matt Blaze is of clipper chip fame
[dscrdvrsc] <dukeleto> if anything, he is a very informed and knowledgeable devil's advocate, and does deal with day-to-day election machine security
[dscrdvrsc] <dukeleto> i imagine he is pretty jaded by that
[dscrdvrsc] <dukeleto> I would love for Verus to prove him wrong, so all those time-locked coins will buy me an island to retire on
[dscrdvrsc] <0x03> what, no lambo?
[dscrdvrsc] <0x03> scnr
[dscrdvrsc] <miketout> could be that and the centralized solutions that charge millions of $ to run an election on a private blockchain, where the software looks cool, but they are in as much control over the security as if they used Diebold machines. They gain ground because of ignorance and that ignorance obscuring even the existence of the problems to solve and the value of real solutions, just as scammers obscure blockchain benefits. claiming "all", as if he's an actual expert on the projects he doesn't take time to learn about just spreads ignorance and makes a real solution more difficult to discover and use. if he would make actual credible claims, like "I haven't seen" or "I would like to see" or "I'll give xxx in my challenge to see", then he might contribute value to the discussion(edited)
[dscrdvrsc] <miketout> clipper chip - makes a little more sense now. it looks like he did good work on that, which earned his fame. would be nice to see him back up his current criticisms with a paper like that vs. blanket tweets(edited)
[dscrdvrsc] <grewalsatinder> we are already testing a test assetchain with privacy only chain, but I wonder if we can use verus algo instead of equihash
GatewayBOT30-Aug-18 06:30 AM
[dscrdvrsc] <miketout> it's possible. i haven't ever tested it
[dscrdvrsc] <miketout> verushash isn't integrated into the main Komodo yet, and I'm just helping do it in CHIPS. if it was done in Komodo as a one off, without a proper merge, it would almost certainly make it much harder to get other tech moved over.
[dscrdvrsc] <grewalsatinder> we are testing it right now, if want to join us in #staked channel in KMD discord
[dscrdvrsc] <grewalsatinder> I guess verus code must have the privacy ac params code in it
[dscrdvrsc] <grewalsatinder> means the verucoin forked code
[dscrdvrsc] <grewalsatinder> and if using verus komodod I want to make this privacy only chain, would love to know what will be the suitable params
GatewayBOT30-Aug-18 10:25 AM
[dscrdvrsc] <dukeleto> @miketout @grewalsatinder I am happy to inform you both that -ac_private is already included in Verus master branch: https://github.com/VerusCoin/VerusCoin/commit/2f151c301925c9959d62d52a82d6ddcbe7971f00 and since -ac_private chains cant have any PoS, it's not compatible with Verus itself, and I am not sure if Verus asset chains will be 50/50 PoS or configurable, but in theory you should be able to use VerusHash + -ac_private together on a pure PoW chain
[dscrdvrsc] <grewalsatinder> so can specify verus 100% PoW ?
[dscrdvrsc] <grewalsatinder> if so can have a verushash PoW privacy only chain
[dscrdvrsc] <grewalsatinder> looked at the verusd script. if just copy it then a privacy only chain will have this command:
./komodod -ac_name=ARRGH -ac_algo=verushash -ac_cc=1 -ac_supply=0 -ac_eras=3 -ac_reward=0,38400000000,2400000000 -ac_halving=1,43200,1051920 -ac_decay=100000000,0,0 -ac_end=10080,226080,0 -ac_timelockgte=19200000000 -ac_timeunlockfrom=129600 -ac_timeunlockto=1180800 -ac_veruspos=0 -ac_private=1(edited)
[dscrdvrsc] <grewalsatinder>
[dscrdvrsc] <grewalsatinder> just changed pos to 0 and added privacy and renamed the name
-ac_veruspos=0 -ac_private=1
Existing single qubit systems not needing quantum entanglement allow seemingly arbitrarily fast computation, violating the previously-"proven" limit. New limit is unknown. May invalidate POW hashing & crypto keys w/o full QM computers
https://t.co/y58fJIXwo1
[dscrdvrsc] <dukeleto> If I read that correctly, it means "omg quantum computers can be waaay faster than we thought"

Description
The naive strategy aims to increase or decrease the application's capacity by using horizontal scaling at both virtualization levels: Containers and Virtual Machines. As a drawback, the cost-efficiency of this approach highly depends on the resource limit constraints assigned to the pod and VM type defined by the system administrator at the moment of the first application deployment. It means that the system administrator requires a high expertise and knowledge about the application in order to set an optimal configuration.


The goal of this project is to demonstrate a flexible, adaptive means of communicating healthcare information in a form that is suitable for exchange between health care organizations and patients for clinical, research, and evidence-based medical practice, as envisioned by the President’s Council of Advisors on Science and Technology (PCAST [PCAST2010] ). In 2010, PCAST issued a report entitled “Realizing the Full Potential of Health Information Technology to Improve Healthcare for Americans: The Path Forward” calling for a universal exchange language to improve the quality of healthcare and reduce its cost:
"The best way to give clinicians a unified, patientcentric record tailored for each medical encounter is to store, maintain, update, and exchange the data as small, distributed, metadatatagged elements"
The report is cautious about relying on a single "standard data model"
"We believe that any attempt to create a national health IT ecosystem based on standardized record formats is doomed to failure."
It recommends a language that promotes distributed definition of expression ("a universal exchange language whose semantics is intrinsically extensible") so that the government and others can
"unburden itself of a potentially never ending and intrusive government role in the harmonization of health record meanings across all private sector products."
On one hand, this call for a metadata-based model is a fundamentally new vision of how we handle health information. On the other hand, it is a confirmation of the approach that has been used successfully for decades in both the VA VistA and the DoD CHCS systems, in the form of a metadata-driven data dictionary system.

Biggest Modeling Problems and How to Solve Them
by pavlapavla writes:
Are you haunted by your modeling mistakes?
We've just unlocked a LIVESTREAM with Jonathan Lampel in which he goes over member-submitted modeling problems and comes up with efficient solutions.
From edge loops that are out of control, something that just doesn't reflect the right way, or a shape you're not sure how to make.
Questions include: "Hands and feet are so topology dense, how do I prevent the density from creeping up the whole arm/leg?" or "How do I know when to stop sculpting?"
Keep in mind, this is a recorded livestream with member engagement...but tons of useful tips!

What Intrusion Detection System (IDS) does UKCloud provide?
Overview
An Intrusion Detection System (IDS) examines incoming network traffic to identify potential malicious activities, such as attempts to gain unauthorised access to an application or corrupt application data, and reports such attempts to a monitoring service.
IDS for Assured OFFICIAL
For Assured OFFICIAL solutions, we do not offer network IDS as part of our standard offering. We are planning to be able to enable network IDS as a cost option for customers who are buying additional Assured OFFICIAL Protective Monitoring from QinetiQ. Although our IDS solution can address activity based threats (such as port scans or SYN floods), it is less effective at addressing payload threats as the traffic is typically encrypted when it passes through our IDS solution. Hence, we recommend that customers implement their own application firewall, network IDS/IPS (within their virtual data centre) and/or host based IDS/IPS. In this way, customers have complete control over the policies and the resulting audit logs. Customers can also consider implementing a Content Delivery Network (CDN) in front of the UKCloud solution. All traffic will flow through the CDN, which often provides IDS/IPS features and can deal with issues such as Distributed Denial of Service (DDoS) attacks.
IDS for Elevated OFFICIAL
For Elevated OFFICIAL solutions, we implement network IDS at our perimeter firewall and all logs are actively monitored via a GPG13 aligned Protective Monitoring service provided by QinetiQ (a UKCloud Alliance Partner). Although the solution can address activity based threats (such as port scans or SYN floods), it is less effective at addressing payload threats as the traffic is typically encrypted when it passes through our IDS solution. Hence, we recommend that customers implement additional IDS/IPS within their cloud solution as appropriate.
Third-party solutions
Although we do not recommend specific third-party services, we are aware of the following solutions:
Cisco FirePOWER – www.cisco.com/c/en/us/products/security/ngips/index.html
Brocade Virtual Traffic Manager – www.brocade.com/en/products-services/application-delivery-controllers/virtual-traffic-manager.html

How to validate a JSON object in java?¶
Request validation¶
When you implement a REST API using json, apparently, you need to validate json requests somehow. Using JSON Schema might be an overkill and, all in all, a tedious task. Binding validation to a data model, an approach often used in Java Spring, doesn’t seem to be good either: validation and data model should be independent from each other.
Response validation¶
Besides validating json requests, you might want to validate some third-party service json responses. Depending on whether it’s successful or not, you want different code branches to execute. From the practical point of view, there is actually no difference what to validate, be it a request or response.
Validate json anywhere¶
Json validation with validol library is standing on the shoulders of giants: it encourages context-specific validation and declarative code. The resulting code is concise, extendable, and maintainable.
What to use for json validation¶
You might want to give validol a shot. Here is how a json object validation could look like:
{
"discount":{
"valid_until":"2032-05-04 00:00:00+07",
"promo_code":"VASYA1988"
}
}
Here is how the actual validation code looks like:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 | public class ValidatedJsonObjectRepresentingRequestOrResponse implements Validatable<JsonObjectRepresentingRequestOrResponse>
{
private String jsonString;
private Connection dbConnection;
public ValidatedJsonObjectRepresentingRequestOrResponse(String jsonString, Connection dbConnection)
{
this.jsonString = jsonString;
this.dbConnection = dbConnection;
}
@Override
public Result<JsonObjectRepresentingRequestOrResponse> result() throws Exception
{
return
new FastFail<>(
new WellFormedJson(
new Unnamed<>(Either.right(new Present<>(this.jsonRequestString)))
),
requestJsonObject ->
new UnnamedBlocOfNameds<>(
List.of(
new FastFail<>(
new IsJsonObject(
new Required(
new IndexedValue("discount", requestJsonObject)
)
),
discountObject ->
new NamedBlocOfNameds<>(
"discount",
List.of(
new PromoCodeIsNotExpired(
new AsString(
new Required(
new IndexedValue("valid_until", discountObject)
)
)
),
new PromoCodeIsNotAlreadyRedeemed(
new PromoCodeContainsBothLettersAndDigits(
new Required(
new IndexedValue("promo_code", discountObject)
)
),
this.dbConnection
)
),
Discount.class
)
)
),
JsonObjectRepresentingRequestOrResponse.class
)
)
.result()
;
}
}
|
Let’s see what’s going on here, line by line:
Line 1
Declaration of ValidatedJsonObjectRepresentingRequestOrResponse
.Line 6
Its constructor accepts raw json string. It might be either an incoming request or received response, or pretty much anything else.Line 13
: Validation starts when this method is invoked.Lines 16
: The higher-level validation object is FastFail
block. If the first argument is invalid, an error is returned right away.Lines 17-19
: json is checked whether it’s well-formed or not. If the latter, validation fails fast and returns a corresponding error.Line 20
: if json is well-formed, a closure is invoked, and json data is passed as its single argument.Line 21
: json data is validated. Its structure is an unnamed block of named blocks. It corresponds to a JSON Object.Line 26
: The first (and the only) block is called discount
.Line 25
: It’s required.Line 24
: It must be a json object.Line 23
: If not, an error will be returned right away because it’s a FailFast
object.Line 29
: Otherwise, a closure is invoked.Line 30
: Discount block is a named block consisting of other named entries – objects or scalars.Line 36
: The first one is called valid_until
Line 35
: It’s required.Line 34
: And represented as a string.Line 33
: Finally, check that it’s not expired.Line 43
: Second parameter is called promo_code
.Line 42
: It’s required as well.Line 41
: It must contain both letters and digits.Line 40
: And it should not be already redeemed. This fact is certainly persisted in our database, hence …Line 46
: … this.dbConnection
parameter.Line 49
: If all previous validation checks are successful, an object of class Discount
is created.Line 53
: Finally, JsonObjectRepresentingRequestOrResponse
is created and returned.Here is how a calling code looks when validation is successful:
Result<JsonObjectRepresentingRequestOrResponse> result = new ValidatedJsonObjectRepresentingRequestOrResponse(jsonRequestString).result();
result.isSuccessful();
result.value().raw().discount().promoCode(); // VASYA1988

Issue: DEFGENERIC-DECLARE
References: 88-002R p.2-27
Category: ADDITION
Edit history: 29-Apr-90, Version 1 by Moon
30-Apr-90, Version 2 by Moon (update current practice)
Problem description:
DEFGENERIC only allows DECLARE to appear once, which is inconsistent with
DEFUN, which allows any number of DECLAREs.
This is Symbolics issue #23.
Proposal (DEFGENERIC-DECLARE:ALLOW-MULTIPLE):
Allow the DECLARE option to appear multiple times in a DEFGENERIC form.
The multiple declarations are appended together.
Rationale:
Programmers rely on the syntactic analogy between DEFGENERIC and DEFUN.
Note that some implementations allow several implementation-dependent
declarations in DEFGENERIC, so the list of declarations in a DEFGENERIC
could be quite long.
Current practice:
Symbolics Genera 8.0 only allows DECLARE to appear once.
Lucid 4.0.0 Beta-1 allows DECLARE to appear multiple times.
Cost to Implementors:
Easy.
Cost to Users:
None.
Cost of non-adoption:
DEFGENERIC would be inconsistent with all other forms that allow DECLARE
to be used to specify declarations.
Performance impact:
None.
Benefits:
More consistent language.
Esthetics:
More consistent language.
Discussion:
None.


When working with big data sets, RAM conservation is critically important. However, it is not always enough to just monitor the size of the objects created. So-called "copy-on-modify" behavior, characteristic of R, means that some expressions or functions may require an unexpectedly large amount of RAM overhead. For example, replacing a single value in a matrix duplicates that matrix in the back-end, making this task require twice as much RAM as that used by the matrix itself. This package makes it easy to monitor the total and peak RAM used so that developers can quickly identify and eliminate RAM hungry code.

The Metropolis et al. algorithm was invented by Metropolis et. a and is often simply called the Metropolis algorithm. It is a method to sample a normalized probability distribution by a stochastic process. We define \( {\cal P}_i^{(n)} \) to be the probability for finding the system in the state \( i \) at step \( n \). The algorithm is then
We wish to derive the required properties of \( T \) and \( A \) such that \( {\cal P}_i^{(n\rightarrow \infty)} \rightarrow p_i \) so that starting from any distribution, the method converges to the correct distribution. Note that the description here is for a discrete probability distribution. Replacing probabilities \( p_i \) with expressions like \( p(x_i)dx_i \) will take all of these over to the corresponding continuum expressions.
The dynamical equation for \( {\cal P}_i^{(n)} \) can be written directly from the description above. The probability of being in the state \( i \) at step \( n \) is given by the probability of being in any state \( j \) at the previous step, and making an accepted transition to \( i \) added to the probability of being in the state \( i \), making a transition to any state \( j \) and rejecting the move:
$$ \begin{equation} \label{eq:eq1} {\cal P}^{(n)}_i = \sum_j \left [ {\cal P}^{(n-1)}_jT_{j\rightarrow i} A_{j\rightarrow i} +{\cal P}^{(n-1)}_iT_{i\rightarrow j}\left ( 1- A_{i\rightarrow j} \right) \right ] \,. \end{equation} $$Since the probability of making some transition must be 1, \( \sum_j T_{i\rightarrow j} = 1 \), and Eq. \eqref{eq:eq1} becomes
$$ \begin{equation} {\cal P}^{(n)}_i = {\cal P}^{(n-1)}_i + \sum_j \left [ {\cal P}^{(n-1)}_jT_{j\rightarrow i} A_{j\rightarrow i} -{\cal P}^{(n-1)}_iT_{i\rightarrow j}A_{i\rightarrow j} \right ] \,. \label{_auto1} \end{equation} $$For large \( n \) we require that \( {\cal P}^{(n\rightarrow \infty)}_i = p_i \), the desired probability distribution. Taking this limit, gives the balance requirement
$$ \begin{equation} \sum_j \left [p_jT_{j\rightarrow i} A_{j\rightarrow i}-p_iT_{i\rightarrow j}A_{i\rightarrow j} \right ] = 0, \label{_auto2} \end{equation} $$The balance requirement is very weak. Typically the much stronger detailed balance requirement is enforced, that is rather than the sum being set to zero, we set each term separately to zero and use this to determine the acceptance probabilities. Rearranging, the result is
$$ \begin{equation} \frac{ A_{j\rightarrow i}}{A_{i\rightarrow j}} = \frac{p_iT_{i\rightarrow j}}{ p_jT_{j\rightarrow i}} \,. \label{_auto3} \end{equation} $$The Metropolis choice is to maximize the \( A \) values, that is
$$ \begin{equation} A_{j \rightarrow i} = \min \left ( 1, \frac{p_iT_{i\rightarrow j}}{ p_jT_{j\rightarrow i}}\right ). \label{_auto4} \end{equation} $$Other choices are possible, but they all correspond to multilplying \( A_{i\rightarrow j} \) and \( A_{j\rightarrow i} \) by the same constant smaller than unity. The penalty function method uses just such a factor to compensate for \( p_i \) that are evaluated stochastically and are therefore noisy.
Having chosen the acceptance probabilities, we have guaranteed that if the \( {\cal P}_i^{(n)} \) has equilibrated, that is if it is equal to \( p_i \), it will remain equilibrated. Next we need to find the circumstances for convergence to equilibrium.
The dynamical equation can be written as
$$ \begin{equation} {\cal P}^{(n)}_i = \sum_j M_{ij}{\cal P}^{(n-1)}_j \label{_auto5} \end{equation} $$with the matrix \( M \) given by
$$ \begin{equation} M_{ij} = \delta_{ij}\left [ 1 -\sum_k T_{i\rightarrow k} A_{i \rightarrow k} \right ] + T_{j\rightarrow i} A_{j\rightarrow i} \,. \label{_auto6} \end{equation} $$Summing over \( i \) shows that \( \sum_i M_{ij} = 1 \), and since \( \sum_k T_{i\rightarrow k} = 1 \), and \( A_{i \rightarrow k} \leq 1 \), the elements of the matrix satisfy \( M_{ij} \geq 0 \). The matrix \( M \) is therefore a stochastic matrix.
The Metropolis method is simply the power method for computing the right eigenvector of \( M \) with the largest magnitude eigenvalue. By construction, the correct probability distribution is a right eigenvector with eigenvalue 1. Therefore, for the Metropolis method to converge to this result, we must show that \( M \) has only one eigenvalue with this magnitude, and all other eigenvalues are smaller.
Even a defective matrix has at least one left and right eigenvector for each eigenvalue. An example of a defective matrix is
$$ \begin{bmatrix} 0 & 1\\ 0 & 0 \\ \end{bmatrix}, $$with two zero eigenvalues, only one right eigenvector
$$ \begin{bmatrix} 1 \\ 0\\ \end{bmatrix} $$and only one left eigenvector \( (0\ 1) \).
The Gershgorin bounds for the eigenvalues can be derived by multiplying on the left with the eigenvector with the maximum and minimum eigenvalues,
$$ \begin{align} \sum_i \psi^{\rm max}_i M_{ij} =& \lambda_{\rm max} \psi^{\rm max}_j \nonumber\\ \sum_i \psi^{\rm min}_i M_{ij} =& \lambda_{\rm min} \psi^{\rm min}_j \label{_auto7} \end{align} $$Next we choose the normalization of these eigenvectors so that the largest element (or one of the equally largest elements) has value 1. Let's call this element \( k \), and we can therefore bound the magnitude of the other elements to be less than or equal to 1. This leads to the inequalities, using the property that \( M_{ij}\geq 0 \),
$$ \begin{eqnarray} \sum_i M_{ik} \leq \lambda_{\rm max} \nonumber\\ M_{kk}-\sum_{i \neq k} M_{ik} \geq \lambda_{\rm min} \end{eqnarray} $$where the equality from the maximum will occur only if the eigenvector takes the value 1 for all values of \( i \) where \( M_{ik} \neq 0 \), and the equality for the minimum will occur only if the eigenvector takes the value -1 for all values of \( i\neq k \) where \( M_{ik} \neq 0 \).
That the maximum eigenvalue is 1 follows immediately from the property that \( \sum_i M_{ik} = 1 \). Similarly the minimum eigenvalue can be -1, but only if \( M_{kk} = 0 \) and the magnitude of all the other elements \( \psi_i^{\rm min} \) of the eigenvector that multiply nonzero elements \( M_{ik} \) are -1.
Let's first see what the properties of \( M \) must be to eliminate any -1 eigenvalues. To have a -1 eigenvalue, the left eigenvector must contain only \( \pm 1 \) and \( 0 \) values. Taking in turn each \( \pm 1 \) value as the maximum, so that it corresponds to the index \( k \), the nonzero \( M_{ik} \) values must correspond to \( i \) index values of the eigenvector which have opposite sign elements. That is, the \( M \) matrix must break up into sets of states that always make transitions from set A to set B ... back to set A. In particular, there can be no rejections of these moves in the cycle since the -1 eigenvalue requires \( M_{kk}=0 \). To guarantee no eigenvalues with eigenvalue -1, we simply have to make sure that there are no cycles among states. Notice that this is generally trivial since such cycles cannot have any rejections at any stage. An example of such a cycle is sampling a noninteracting Ising spin. If the transition is taken to flip the spin, and the energy difference is zero, the Boltzmann factor will not change and the move will always be accepted. The system will simply flip from up to down to up to down ad infinitum. Including a rejection probability or using a heat bath algorithm immediately fixes the problem.
Next we need to make sure that there is only one left eigenvector with eigenvalue 1. To get an eigenvalue 1, the left eigenvector must be constructed from only ones and zeroes. It is straightforward to see that a vector made up of ones and zeroes can only be an eigenvector with eigenvalue 1 if the matrix element \( M_{ij} = 0 \) for all cases where \( \psi_i \neq \psi_j \). That is we can choose an index \( i \) and take \( \psi_i = 1 \). We require all elements \( \psi_j \) where \( M_{ij} \neq 0 \) to also have the value \( 1 \). Continuing we then require all elements \( \psi_\ell \) $M_{j\ell}$ to have value \( 1 \). Only if the matrix \( M \) can be put into block diagonal form can there be more than one choice for the left eigenvector with eigenvalue 1. We therefore require that the transition matrix not be in block diagonal form. This simply means that we must choose the transition probability so that we can get from any allowed state to any other in a series of transitions.
Finally, we note that for a defective matrix, with more eigenvalues than independent eigenvectors for eigenvalue 1, the left and right eigenvectors of eigenvalue 1 would be orthogonal. Here the left eigenvector is all 1 except for states that can never be reached, and the right eigenvector is \( p_i > 0 \) except for states that give zero probability. We already require that we can reach all states that contribute to \( p_i \). Therefore the left and right eigenvectors with eigenvalue 1 do not correspond to a defective sector of the matrix and they are unique. The Metropolis algorithm therefore converges exponentially to the desired distribution.
The requirements for the transition \( T_{i \rightarrow j} \) are
For a diffusion process characterized by a time-dependent probability density \( P(x,t) \) in one dimension the Fokker-Planck equation reads (for one particle /walker)
$$ \frac{\partial P}{\partial t} = D\frac{\partial }{\partial x}\left(\frac{\partial }{\partial x} -F\right)P(x,t), $$where \( F \) is a drift term and \( D \) is the diffusion coefficient.
The new positions in coordinate space are given as the solutions of the Langevin equation using Euler's method, namely, we go from the Langevin equation
$$ \frac{\partial x(t)}{\partial t} = DF(x(t)) +\eta, $$with \( \eta \) a random variable, yielding a new position
$$ y = x+DF(x)\Delta t +\xi\sqrt{\Delta t}, $$where \( \xi \) is gaussian random variable and \( \Delta t \) is a chosen time step. The quantity \( D \) is, in atomic units, equal to \( 1/2 \) and comes from the factor \( 1/2 \) in the kinetic energy operator. Note that \( \Delta t \) is to be viewed as a parameter. Values of \( \Delta t \in [0.001,0.01] \) yield in general rather stable values of the ground state energy.
The process of isotropic diffusion characterized by a time-dependent probability density \( P(\mathbf{x},t) \) obeys (as an approximation) the so-called Fokker-Planck equation
$$ \frac{\partial P}{\partial t} = \sum_i D\frac{\partial }{\partial \mathbf{x_i}}\left(\frac{\partial }{\partial \mathbf{x_i}} -\mathbf{F_i}\right)P(\mathbf{x},t), $$where \( \mathbf{F_i} \) is the \( i^{th} \) component of the drift term (drift velocity) caused by an external potential, and \( D \) is the diffusion coefficient. The convergence to a stationary probability density can be obtained by setting the left hand side to zero. The resulting equation will be satisfied if and only if all the terms of the sum are equal zero,
$$ \frac{\partial^2 P}{\partial {\mathbf{x_i}^2}} = P\frac{\partial}{\partial {\mathbf{x_i}}}\mathbf{F_i} + \mathbf{F_i}\frac{\partial}{\partial {\mathbf{x_i}}}P. $$
The drift vector should be of the form \( \mathbf{F} = g(\mathbf{x}) \frac{\partial P}{\partial \mathbf{x}} \). Then,
$$ \frac{\partial^2 P}{\partial {\mathbf{x_i}^2}} = P\frac{\partial g}{\partial P}\left( \frac{\partial P}{\partial {\mathbf{x}_i}} \right)^2 + P g \frac{\partial ^2 P}{\partial {\mathbf{x}_i^2}} + g \left( \frac{\partial P}{\partial {\mathbf{x}_i}} \right)^2. $$The condition of stationary density means that the left hand side equals zero. In other words, the terms containing first and second derivatives have to cancel each other. It is possible only if \( g = \frac{1}{P} \), which yields
$$ \mathbf{F} = 2\frac{1}{\Psi_T}\nabla\Psi_T, $$which is known as the so-called quantum force. This term is responsible for pushing the walker towards regions of configuration space where the trial wave function is large, increasing the efficiency of the simulation in contrast to the Metropolis algorithm where the walker has the same probability of moving in every direction.
The Fokker-Planck equation yields a (the solution to the equation) transition probability given by the Green's function
$$ G(y,x,\Delta t) = \frac{1}{(4\pi D\Delta t)^{3N/2}} \exp{\left(-(y-x-D\Delta t F(x))^2/4D\Delta t\right)} $$which in turn means that our brute force Metropolis algorithm
$$ A(y,x) = \mathrm{min}(1,q(y,x))), $$with \( q(y,x) = |\Psi_T(y)|^2/|\Psi_T(x)|^2 \) is now replaced by the Metropolis-Hastings algorithm as well as Hasting's article,
$$ q(y,x) = \frac{G(x,y,\Delta t)|\Psi_T(y)|^2}{G(y,x,\Delta t)|\Psi_T(x)|^2} $$We are now ready to implement importance sampling. This is done here for the two-electron case with the Coulomb interaction, as in the previous example. We have two variational parameters \( \alpha \) and \( \beta \). After the set up of files

Donald Trump reportedly screened ‘Joker’ at the White House – and he’s a fan
US President apparently hosted a screening of the movie over the weekend.
Donald Trump has reportedly watched Joker at the White House, and is apparently a fan of the movie.
According to journalist Shimon Prokupecz, the US President hosted a screening of the Todd Phillips movie over the weekend, which was later confirmed by Yahoo News.
The site reports that a senior White House official said “family, friends, and some staff” were in attendance, and that Trump liked the movie.
- Read more: A huge ‘Joker’ mystery has been solved
Joker has attracted some controversy due to its violence, and star Joaquin Phoenix recently addressed the potential violence implications of the movie.
“It was an awkward position to be in because I thought, ‘Well, I can’t address this because this is the thing that is potentially part of the problem — that’s precisely what you shouldn’t do,” he said.
“It suddenly seemed like I was being evasive and trying to avoid this topic because it made me uncomfortable,” he explained. “But really I was thinking, ‘This is the very thing that would excite this kind of personality.’”
Joaquin Phoenix in ‘Joker’
Director Todd Phillips has since addressed concerns, saying: To me, I thought, isn’t it a good thing to put real-world implications on violence? Isn’t it a good thing to take away the cartoon element of violence that we’ve become so immune to?”
Meanwhile, Phillips recently opened-up where a potential Joker sequel could go, saying: “It couldn’t just be this wild and crazy movie about the ‘Clown Prince of Crime,’” Phillips said. “It would have to have some thematic resonance in a similar way that [‘Joker’] does.
“I think that’s ultimately why the movie connected, it’s what’s going on underneath. So many movies are about the spark, and this is about the powder. If you could capture that again in a real way, that would be interesting.”
Joker recently became the most profitable comic book movie ever as well as highest-grossing R-rated movie of all time.

Traseia
Traseia Dungeon
Come discover the beautiful Isles that are Traseia. This lovely new area offers you double experience and booty but to gain access one must hold a rare blue ticket. Purchasable from the , these little stubs shall soon be in large demand by your fellow Madrigolians. Traseia Ticket History Once a piece of Roika that was torn asunder by Shade during the War of the Gods, this grouping of islands has drifted aimlessly through time. The fiercest of Shades minions, the Terrorpin Tribe, invaded this land at Her command long before the conclusion of the War. The Terrorpins had no trouble establishing dominance over the peaceful inhabitants of this land. The rabbit-like natives were not accustomed to war and were caught largely unaware and completely unprepared for the invasion on their home front. Only the strongest and most brave of the rabbit natives remain, and even then, they are only able to carve out one small isle for their own. Tempered by their experience, the Sakai are no longer welcoming visitors with open arms. The Terrorpin Tribe, is now led by their gigantic chieftain Guan Yu Heavyblade. He rules atop the largest floating isle in his arena waiting for a challenge to his crown. By chance or fate, Traseia has drifted near to Madrigal and adventurers are already planning ways to discover its lost treasures.

Handling Page Review Problems
The “page review” location is one of the most dangerous in the application due to the requirement that people manually edit and rename files. There are potentially a lot of difficult problems to manage here.
Manual Deletion
If issues got to the page-review step when they shouldn’t have, the only option is to remove them. Make sure you do this right. There is a tool for this process, and manually deleting issues will cause you pain (see below).
To use the tool, build NCA with make
, and run ./bin/page-review-issue-fixer -c ./settings --key ...
. You can specify multiple issue keys or even a file
full of issue keys. Use --help
for a complete explanation.
Once this tool runs, if all goes well the issues will get queued up and moved to the configured error location. From there you can do whatever you like with the issues, as described in Fixing Flagged Workflow Issues.
Accidental Deletion
Sometimes a helpful curator deletes the issues manually, not being aware this shouldn’t happen. On these occasions, manual cleanup is required, and it gets very ugly.
Identify the deleted issues
If you don’t know offhand what’s been deleted, but you’ve seen log errors about the page review location, this might help.
cat /var/log/nca-* | grep " - ERROR - " | \
sed 's|^.* - ERROR - ||' | \
sed 's|^.* \(/mnt/news/.*\): no such file or directory$|\1|' | \
sort | uniq -c | sort -n
This will find all error logs that are due to file or directory being missing. It will likely catch other problems than just page-review deletions, but those can be useful as well. Just note that things like NFS drop can result in occasional one-offs. You really want to look for systemic, repetitive errors. In our case, we saw almost 400 errors per issue because NCA scans the filesystem every few minutes.
(If you’re using a smart logging system like logstash, you can probably identify logs more easily, but you’ll likely need to split logs up to strip off the changing bits so the unique issues can be aggregated and counted)
The database ids are the last number in an issue’s path. e.g.,
/mnt/news/page-review/sn99063854-1925122501-9971
has a database id of 9971.
Fix the data
First, verify that the issues are in fact not on the filesystem. If you see errors about database id 9971, you can query its location:
SELECT location FROM issues WHERE id=9971;
If that location exists, the problem you have is not what is described here.
Assuming the locations are indeed deleted, gather up all your database ids. If you had errors with ids 9971, 9975, and 9990:
UPDATE issues SET
error = 'manually deleted from page-review step',
workflow_step = 'UnfixableMetadataError',
location='',
ignored=1
WHERE id in (9971, 9975, 9990);
The database is fixed!
Delete backups?
If the issues are completely ruined and the backups are known to be bad, you should delete them. Get their locations from the database:
SELECT backup_location FROM issues WHERE id IN (9971, 9975, 9990);
Remove these locations from disk.

Jaejoong reveals that he wants to have kids more than getting married
by sl278Jaejoong made a surprising statement about wanting to have children, leading to him trending on multiple Korean news sites.
The popular star appeared on the most recent broadcast of 'Do You Eat?' where he talked about his daily life and thoughts. He talked about the loneliness of promoting as a solo artist and pursuing an entertainment career for most of his life.
When asked when he was going to date, Jaejoong stated: "Honestly, I really want kids. Now that I'm in my mid-30s, I think of things I didn't before. I saw my brother playing with kids and he told me to have some too, that there's happiness there that I haven't experienced."
What do you think of Jaejoong's announcement?
