The 7 Day Coding Challenge is officially closed. It’s been such a pleasure to share our joy of coding with so many people from all over the world and humbling to hear first hand how much you have enjoyed it.
If you have found this free challenge valuable we would be so grateful if you would consider leaving us a review on our facebook page with feedback for the free mini coding course.
We would also welcome and constructive feedback you have about how we can make this course even better in future. This was our first time running an online program of this scale, and there have been lots of little lessons along the way but we’re always open to hearing your thoughts and feedback via email or DM.
Who would have thought that in only 7 days worth of lessons you could go from zero to building real projects like these…
Want to continue your coding journey? We’ve had lots of questions about where to go from here, and wanted to lay out all of your options.
Keep reading for how to get $100 off Website in a Weekend for the next 7 days only.
If you are thinking of pursuing a career as a web developer, or even just doing web development as a bit of a side hustle (the average website project can earn you from $1500 - $3500) then definitely check out our free workshop on how to become a web developer.
There are so many great coding resources out there, it’s almost overwhelming! Here are a selection of helpful resources to continue your journey if you aren’t yet ready to invest in a paid course <3
We’ve had so many questions about our online course, that we wanted to jump in and answer them here!
1. What does this cover that we haven’t already learnt?
It digs deeper into HTML & CSS, including more advanced styling, and making your website responsive (adapt to mobile and tablet devices). By the end of the course you’ll have the skills and resources to build a complete website from scratch.
2. What kind of website will you be able to build?
At the moment there is one single-page web site template included (more advanced than what you have built currently) and in-depth tutorials allowing you to go beyond this.
Over the next two months we’re adding dozens of new tutorials, additional templates AND these modular website templates – building blocks of HTML & CSS that you can copy + paste + customise to build a brand new website in no time.
If you enroll in the course now, you’ll receive access to all future updates and tutorials at no additional cost.
3. How much does Website in a Weekend cost?
As soon as we release the additional tutorials mentioned above the price will be increasing to $450. It’s currently $250, and we’re giving all 7 day coding challenge participants a coupon ‘7DAYCODING’ to receive $100 off for the next two weeks only.
If you decide to attend the bootcamp later, we’ll credit the amount you spend on Website in a Weekend towards the bootcamp tuition.
4. What kind of support is provided?
We have a private facebook community that is monitored by our experienced mentors where we can help answer your questions and provide technical support.
If you would like one-on-one skype access to our experienced mentors, we can provide packs of 4 hours of support for only $100 (one-on-one support from an experienced developer is normally at least $60 per hour).
5. What if I’m not satisfied with the course?
We believe whole heartedly in our so far have a 100% satisfaction from everyone who has completed the course. Contact us within two weeks of purchase and explain how the program did not meet your expectations for a full refund.
Looking to take things to the next level? Our hybrid bootcamp (6 weeks part time online + 10 day intensive in Bali + lifetime support) might be exactly what you need.
This program goes well beyond the basics and teaches you how to build a freelance career as a web developer (or land a job at an agency if that’s more your thing).
A few highlights in the curriculum:
- learning how to use jQuery (a library for Javascript) to add interactive elements like pop-up lightbox galleries, sliders / carousels, hamburger mobile menus etc.
- how to create dynamic layouts for things like blog posts or project pages
- how to create smooth animations on hover and other transitions
- how to add live chat widget
- how to add custom contact forms that sync with a CRM like Hubspot
- how to create advanced layouts with overlapping elements (like the IOC website)
- how to optimise your website for performance in every browser and on mobile devices
Check out our course page for all the details and examples of student projects!
The main difference though between an online course and in-person immersive is in the practical experience – it’s one thing to understand the theory of specific properties; It’s another thing completely to build an entire website from scratch. We focus in the bootcamp on taking the skills you have learnt in the video modules and applying them, building things and breaking things, learning how to troubleshoot and write efficient code. So that by the time you finish the program you can confidently build website for yourself or clients, from start to finish.
We also cover how to take these skills and build them into a business, including how to find build an effective portfolio, find and pitch to clients, scope and price projects etc. We give our students everything they need to hit the ground running and start working on real client projects – and it’s not uncommon for students to land their first paying client less than one month after the bootcamp.
Oh, and it doesn’t hurt that our program is all-inclusive in this beautiful villa in Bali complete with chef prepared meals and daily yoga to help you get into the flow state ideal for learning.
Thinking about attending the bootcamp? We’ve put aside 2x $500 partial scholarships for those of you who have putting in the hard work and dedication to completing this 7 day challenge. For more details and your chance to receive one of these scholarships apply via our website mentioning this and then book a call to chat with our course advisor Terry or co-founder Tina.


15 TSRTC employees taken into custody for protesting in Hyderabad: Police
The RTC Joint Action Committee (JAC) has called for a 'Bus roko' protest in Telangana on Saturday.
by ANIHyderabad: Nearly 15 Telangana State Road Transport Corporation (TSRTC) employees were taken into custody by Falaknuma Police on Saturday when they were protesting in front of Farooq Nagar bus depot here.
The RTC Joint Action Committee (JAC) has called for a 'Bus roko' protest in Telangana on Saturday.
Police personnel have been deployed in large numbers in places near bus depots. Section 144 has been imposed in the state.
Striking employees of TSRTC have decided to temporarily drop their main demand for the Corporation's merger with the government.
The JAC took the decision to keep aside the demand as the government showed no signs of softening its stand on the 41st day of the protest on November 14.
The employees have now asked the government to fulfil their other demands.
The employees have been on a strike since October 5 with several demands including revision of pay.
At least five RTC employees have committed suicide since the commencement of the strike.

Explaining OWASP Top10 (v2013)
OWA...huh?
... is an online community which creates freely-available articles, methodologies, documentation, tools, and technologies in the field of web application security.
The Open Web Application Security Project (OWASP) is a 501(c)(3) worldwide not-for-profit charitable organization focused on improving the security of software. Our mission is to make software security visible, so that individuals and organizations are able to make informed decisions
Why should anyone attack my site?
"Hackers" attack to ...
... wtf? Why is this a problem???
https://some.web/login?redirect=http%3A%2F%2Fhack.me%2Fqwe
$goto = $_GET['redirect']; // place1
$redirectMap = array(
'place1' => $baseUrl . '/where/to',

);
if (array_key_exists($goto, $redirectMap)) {
$redirectUrl = $redirectMap[$goto];
} else {
$redirectUrl = $deaultPage;

... huh? Why should this happen?
Use tools like

Sooo, no problem with that?? If amazon allows this??

What kind of data do we speak here?
How to prevent that?
Like the greek hydra ... it has many heads to bite you

I am MR.MATTEW MOLEFE, the Auditor General in National Credit Bank (NCB) of South Africa, during the course of our auditing I discovered a floating fund in an account opened in the bank in 1993 and since 1999 nobody has operated on this account again, after going through some old files in the records I discovered that the owner of the account died without a [heir] hence the money is floating and if I do not remit this money out urgently it will be forfeited for nothing. The owner of this account is Mr. Jurgen T.Dormann, a foreigner, and a sailor, and he died, since 1999. And no other person knows about this account or any thing concerning it, the account has no other beneficiary and my investigation proved to me as well that Jurgen T.Dormann until his death was the Coy.

I need your strong assurance that you will never, never let me down. With my influence and the position of the bank official we can transfer this money to any foreigner's reliable account, which you can provide with assurance that this money will be intact pending our physical arrival in your country for sharing.

Could some one please tell me what is wrong with my code. I have defined a inductive type and trying to make it instance of has_repr, but getting this error "equation compiler error, equation #2 has not been used in the compilation, note that the left-hand-side of equation #1 is a variable"
inductive day : Type | monday : day | tuesday : day | wednesday : day | thursday : day | friday : day | saturday : day | sunday : day protected def day.repr : day → string | monday := "monday" | tuesday := "tuesday" | wednesday := "wednesday" | thursday := "thursday" | friday := "friday" | saturday := "saturday" | sunday := "sunday" instance : has_repr day := (day.repr)
Put everything into the namespace day
inductive day : Type | monday : day | tuesday : day | wednesday : day | thursday : day | friday : day | saturday : day | sunday : day namespace day protected def repr : day → string | monday := "monday" | tuesday := "tuesday" | wednesday := "wednesday" | thursday := "thursday" | friday := "friday" | saturday := "saturday" | sunday := "sunday" instance : has_repr day := ⟨day.repr⟩ end day
or open day
before your definition of day.repr
@Joe Thank you very much. I also noticed that my brackets were ( instead of ⟨.
You are welcome.
inductive day : Type | monday : day | tuesday : day | wednesday : day | thursday : day | friday : day | saturday : day | sunday : day protected def day.repr : day → string | day.monday := "monday" | day.tuesday := "tuesday" | day.wednesday := "wednesday" | day.thursday := "thursday" | day.friday := "friday" | day.saturday := "saturday" | day.sunday := "sunday" instance : has_repr day := ⟨day.repr⟩
if you use monday
instead of day.monday
, Lean treats that as a variable
so it's as if you wrote:
inductive day : Type | monday : day | tuesday : day | wednesday : day | thursday : day | friday : day | saturday : day | sunday : day protected def day.repr : day → string | x := "monday" instance : has_repr day := ⟨day.repr⟩
and that's why the second equation would never be used

Appeal court upholds Ganduje’s election
by Abdulganiyu Alabi, KadunaThe Court of Appeal sitting in Kaduna on Friday upheld the election of Governor Abdullahi Umar Ganduje of Kano State.
The court ruled that the appeal filed by Abba Kabiru Yusuf and his party, the People’s Democratic Party (PDP) lacks merit.
The five-man panel of Appeal Court Judges led by Justice Tijjani Abubakar unanimously dismissed the appeal in its entirety and affirmed that Governor Ganduje was elected by the majority of Kano voters.
Meanwhile, counsel to the appellants, the PDP and Abba Kabiru Yusuf, Bashir Yusuf Muhammad said, they will appeal the judgement.
He said, the reasons for the decisions arrived in the judgement had not been given, but they will get the full judgement to know the basis of the judgement before proceeding to the Supreme Court.

Effective ways to Cram up for an exam!
Gulping up everything isn't the best way to study for any exam, so before we begin, if you've a big chunk of time then I would suggest you not to cram up. If not then let's jump straight into what you can do to optimize the time you've got rather than explaining the disadvantages of the same. And NO! I'm not going to tell you the secret of Krish's Dad and how he just flips the book and absorbs everything. But, what I can do is give you some scientifically proven tricks that you can use to store a great chunk of information in your short term memory.
1. Try using the ancient technique of the Memory Palace.
This ancient technique dated back as far as 80 B.C, involves associating ideas or different
content you want to memorize, with places that you're familiar with like your home, a shopping
complex etc. For example; while learning chemical composition of compounds, you might place
H2SO4 in the living room and kitchen will have NaCl. You get the gist.
This trick works because our visual and spatial memory is quite strong and it is easier to
recollect things which are familiar to it.
2. You should also try mnemonic devices wherever possible.
Trying to learn the periodic table? Try this:-
Group 1: HeLiNaKa Ruby Cse Fraud
And the elements being (Helium, Lithium, Sodium, Potassium, Rubidium, Cesium, Francium)
Group 13: B A G I T
The elements being (Boron, Aluminum, Gallium, Indium, Thallium)
Wasn't that easy? You can also create rhymes and songs. The weirder you make them, the better!
3. Take a chill pill.
I know sounds crazy but, trust me. Stress releases cortisol which impairs retrieval of memory.
Therefore, if you are stressed you will have a more difficult time recalling information during
an exam.
So take some deep breaths!
Keeping yourself calm and composed during these stressful situations isn't going to be easy, I
would recommend meditating daily so that you get the charge of your mind and not the other way
around.
4. Feeling distracted?
Try a mini workout!
Studies show that those who've worked out for 15 minutes and then complete a memory task,
complete tasks faster than those that haven't. Even a simple walk can make a difference.
5. Learn about yourself
You need to take a minute and think about the way that is personally suited best for you.
Meta-cognition is the analysis of one's own learning or thinking processes. Studies have found
that students who have poor meta-cognitive skills meaning they lack awareness of assessing their
own strengths and weaknesses perform worse on tests.
So get to know yourself and the ways you've been much more effective in studying and implement
those strategies. If you study better alone than don't let Rahul force you on that night out
"Cramming session".
6. There's also one other really important distinction to make:
Are you cramming late into the night because you know very little about the topic for your
upcoming exam?
Or are you hoping to achieve perfection to an already studied topic?
If you've already studied then
GO TO SLEEP!
There is more than a century's worth of research concluding that sleep is essential for memory
retention. I cannot stress this more. Just sleep okay? Sleep!

Black Friday will throw a lot of deals your way. These are the ones that are actually worth your time and money, writes Elissa Sanci
by Elissa Sanci | NYTAmazon’s Black Friday can be a bit like going to the grocery store while hungry and without a list: You end up with a full shopping cart of things you don’t really want or need. So lest you end up regretting overpaying for that bubblegum-pink ice cream maker, create a list beforehand and log on with a game plan.
To help you prep, I consulted my colleague, Wirecutter Deals editor Nathan Burrow. Based on his years of experience scouring sites for the lowest prices in November for the Wirecutter Deals page, he’s found that you can’t go wrong in these categories.
Small kitchen appliances
Kitchen appliances
Great news for home cooks: There is likely no better time of year to buy kitchen appliances than on Black Friday and during Cyber Week, with the best deals curated in Wirecutter’s guide to the Best Kitchen and Household Deals. No matter the appliance, it would be rare to find it at a lower price than you will in November. You can find everything from stand mixers to pressure cookers to blenders to waffle makers — just make sure you pick a model that has been vetted and recommended by experts.
Smartwatches and fitness trackers
Smartwatch
Maybe you want a smartwatch to monitor your heart rate during your workouts. Maybe you’re a tech junkie, always itching for the newest gadgets. Or maybe you just like the way they look.
Whatever your reasoning for wanting a smartwatch, Black Friday will be the time to finally buy one. If you’re already embedded into Apple culture and don’t care about having the newest release, know that, in Wirecutter’s preview of the best Apple deals, Burrow predicts we’ll see heavy price drops on the Apple Watch Series 4 and Series 3 this holiday season, since the Series 5 was introduced. Apple isn’t always known for offering great holiday discounts, but Apple Watches tend to be an exception. If you’re not invested in Apple products, Android smartwatches and wearable fitness trackers will also see substantial discounts.
Everyday carry items
What does a travel mug, a set of Bluetooth earbuds, and a Bluetooth tracker for your keys have in common? They’re all supremely useful items that will probably fall to their lowest prices during Black Friday and Cyber Week. This is likely because they’re small and relatively inexpensive — and because almost anyone can use them (making them the perfect gift).
Amazon-branded products
There are two times a year when you’ll find the best prices on Amazon-branded merchandise: Amazon’s own Prime Day and Black Friday.
If you’ve been thinking about making the switch to e-readers, for instance, now would be the time to buy the Kindle you’ve been eyeing. Burrow also predicts that Amazon’s discounts will include the lowest prices yet for the newly released third-generation Echo and Echo Dot — a great opportunity to build the smart home of your dreams for a fraction of the original price.
Since the next Prime Day likely won’t be until July 2020, Burrow points out that this is probably your best chance to save on some Amazon-branded products until well into next year.
Televisions (kind of)
A lot of people think Black Friday is the best time to buy a TV. They’re only partially right: Historically, major brand names haven’t seen exceptional sales on their high-end televisions, but substantial deals on slightly lower-end models do pop up.
If name brands don’t mean much to you and you’re looking for the most screen real estate for the lowest price, you’ll find tons of blowout deals. But if you want a good deal on a top-of-the-line TV, Black Friday likely won’t provide the prices you have in mind, a trend Wirecutter picked up on around TV pricing for Prime Day as well. That said, last year Burrow saw discounts on select Samsung, TCL, and Vizio models that knocked a few hundred dollars off their price tags.

Notes
From Wikipedia:
It is named for its creator, Bernard Lewis Welch, and is an adaptation of Student’s t-test, and is more reliable when the two samples have unequal variances and/or unequal sample sizes.
The classic ANOVA is very powerful when the groups are normally distributed and have equal variances. However, when the groups have unequal variances, it is best to use the Welch ANOVA that better controls for type I error (Liu 2015). The homogeneity of variances can be measured with the homoscedasticity function. The two other assumptions of normality and independance remain.
The main idea of Welch ANOVA is to use a weight \(w_i\) to reduce the effect of unequal variances. This weight is calculated using the sample size \(n_i\) and variance \(s_i^2\) of each group \(i=1,...,r\):
\[w_i = \frac{n_i}{s_i^2}\]Using these weights, the adjusted grand mean of the data is:
\[\overline{Y}_{\text{welch}} = \frac{\sum_{i=1}^r w_i\overline{Y}_i}{\sum w}\]where \(\overline{Y}_i\) is the mean of the \(i\) group.
The effect sums of squares is defined as:
\[SS_{\text{effect}} = \sum_{i=1}^r w_i (\overline{Y}_i - \overline{Y}_{\text{welch}})^2\]We then need to calculate a term lambda:
\[\Lambda = \frac{3\sum_{i=1}^r(\frac{1}{n_i-1}) (1 - \frac{w_i}{\sum w})^2}{r^2 - 1}\]from which the F-value can be calculated:
\[F_{\text{welch}} = \frac{SS_{\text{effect}} / (r-1)} {1 + \frac{2\Lambda(r-2)}{3}}\]and the p-value approximated using a F-distribution with \((r-1, 1 / \Lambda)\) degrees of freedom.
When the groups are balanced and have equal variances, the optimal post-hoc test is the Tukey-HSD test (
pingouin.pairwise_tukey()
). If the groups have unequal variances, the Games-Howell test is more adequate (pingouin.pairwise_gameshowell()
).Results have been tested against R.

Impossible to determine precedence and causality between SB characteristics and HIV incidence
Epidemiology of HIV progress over many years/decades
In this study:
Evolution of sociobehavioral characteristics of 29 countries over time
Evolution of HIV transmission dynamics over the same time period
Explore link between the two
Study only as good as data used
Ideally:
Historical data would be easy to find
Countries would have many surveys spanning many years
Our choice of 46 sociobehavioral indicators would always be present
Reality:
Historical data would be easy to find
DHS data prior to 2000 was unreliable
Countries would have many surveys spanning many years
Countries have few and irregularly timed surveys
Our choice of 46 sociobehavioral indicators would always be present
Many latent/missing values in the surveys
Many HIV indicators only started in the early 2000s
Strategy
Use only surveys from 2000 and later
Missing data
Find alternate source for indicator
Impute missing data
Resulting data
83 surveys from 29 countries (with each between 1 and 5 surveys between 2000-2018)
46 indicators
Analysis of sociobehavioral characteristics
Reduce dimensionality using Principal Component Analysis
Visualize surveys on the reduced 2 dimensional PCA space
Cluster countries using concensus clustering technique
Analysis of transmission dynamics
Individual risk of acquiring HIV given by: $\sum_{i=1}^{j} r_{i} * \rho_{i}$
And so
$$\text{New infections[n]} = \beta[n]*\frac{I[n]}{N[n]}*S[n]$$
where:
$r$ is ith exposure event
$\rho$ is the chance of that exposure event leading to infection
$S[n] = \text{number of susceptible in given year}$
$I[n] = \text{number of infected in given year}$
$N[n] = \text{total population in given year}$
$\beta[n] = r * \rho = \text{effective contact rate}$
Effective contact rate $\beta$
$$\text{New infections[n]} = \beta[n]*\frac{I[n]}{N[n]}*S[n]$$
Data from UNAIDS gives $HIV_{Incidence}$ in "per 1000" so:
$$HIV_{Incidence}[n] = \text{New infections[n]} * \frac{1000}{N[n]}$$
$$\iff HIV_{Incidence}[n] = \beta[n]\frac{I[n]}{N[n]} \frac{S[n]}{N[n]} * 1000$$
$$\beta = \frac{HIV_{Incidence}}{HIV_{Prevalence}*(1-HIV_{Prevalence})}$$
Results
Different levels of HIV epidemics seen today unlikely to be a direct result of different evolutions of sociobehavioral characteristics
Difference in levels of HIV incidence across 3 clusters present since early 1990s
Effective contact rate evolved in a similar manner across clusters over same period
Different levels of HIV epidemics today likely to be the result of different initial conditions in nascent epidemics
Small differences in inital effective contact rate can lead to large differences over course of epidemics
Evidence for this in effective contact rate of 1990
Can be hypothesized male circumcision played a role in reducing effective contact rate in countries with high rates of male circumcision
ART coverage and HIV testing likely to bridge the gap across in HIV epidemics
Larger increase in ART coverage and HIV testing since 2005 in countries of Eastern and Southern Africa differences than countries of other 2 clusters
Resulting in faster decrease of effective contact rates of those countries
Over time, will likely lead to faster control of the epidemics in those countries
Further research
Reconstructing effective contact rate prior to 1990
Reconstructing sociobehavrioal profiles of countries prior to 2000
Limitations
Effective contact rate has the advantage of allowing comparisons across HIV epidemics but relis on both HIV incdence and HIV prevalence which may have large errors
Research has shown using a subset of sociobehavrioal indicators can produce better results
Nationally-aggregated data prone to ecological fallacy
Nationally-aggregated data prone to overlooking salience of high-risk key-populations


A brief introduction into how to build a site with yagss.
The following examples are meant to show some of the things you can build with a yagss site. They also show some patterns and quirks for how data is passed around the build system. This is very much a work in progress.
This is an example article showing how to include static components like images in them.
One of the most powerful features of Yagss is how it automatically scales jpeg images in the source directory and parses their metadata, making that metadata availale to the rendering context.
This is simply a collection of snippets of text written in markdown, interspersed with snippets of yaml specifying which template to use.
There is no need for hydration because the DOM never changes after the build process is run.
A short demo of an article featuring charts made with recharts
This is an example article showing how to include interactive charts using the recharts library.
Each figure can be self-contained because each element can have its own call to hydrateRoot. In other words, this doesn’t need to be a “single page application” where there is one root element and every child is rendered by React. I prefer thinking of these as “single div applications.”
Eventually we will want to migrate this example to something that makes charts that are usable prior to calling hydrateRoot.

Hello 2014. Let's see, will I succeed in keeping a journal like I've promised myself many times before? "This time it's different", right? Well is it? Yes, at least in two ways:
But why keep a journal in the first place? Well I think that the struggle to find the right words to say something is fruitfull in many ways. Writing is a Great technology, capital G. But in the process you learn a lot about what you know and what you are. An extra reason to keep a journal is as an exercise in discipline. Kind of like getting up in the morning and going running, you win just by exiting the house. So I could stop right here I suppose and chalk one up.
The empty page however beckons.
My thoughts on the new year are a bit unclear. All through the previous year I had been planning that it would be great in a a particular way. Now, the particulars are wiped away and I have to improvise. Lesson #1 don't dream about particulars, have broader dreams. The major particular that I was dreaming of was my girlfriend moving in with me, and our relationship progressing to new heights. Instead, under the fog of this all important goal, reality brought a sudden and painfull breakup between Christmas and New Years.
The upshot is I can focus more easily on the new job, which I'm excited about and have (broad) hopes about :-D
Here's to an exciting and productive new year for all of you!


txCast
Randomised Bitcoin transaction broadcasting to break timing analysis (configured for testnet, further testing needed).
Motivation
CoinJoin tools enable Bitcoin users to disassociate the past & future history of their bitcoin UTXOs (through a process called mixing). Users move their mixed coins to a secondary wallet for more secure storage (e.g. a Cold Wallet / Hardware wallet) and are potentially vulnerable to a timing attack whereby blockchain analysts cluster UTXO’s using timing information (if users move multiple mixed coins in a short time period).
Overview
txCast enables Bitcoin users to introduce a random and automated time delay between signed transaction broadcasts.
Use:
Users copy signed transactions from their wallet of choice and paste them into the terminal individually. They are prompted to enter the time delay which they are able to tolerate in minutes, hours and days.
Signed transactions are broadcast using the blockstream.info API over tor with IP addresses changing between each broadcast.
Setup:
Install tor. These are the instructions for linux:
sudo apt install tor
sudo service tor start
tor --hash-password test
<- Don’t use test for mainnet- edit /etc/tor/torrc & uncomment
ControlPort 9051
HashedControlPassword 16:00000
<- Change this number to the output of step 3 sudo service tor stop
sudo service tor start
- Set password to the password you entered in Step 3 on line 12 of the code (
password = "test"
)
Download the python script
Install following python packages:
Run the script with python3 txCast.py
Important Note: The Blockstream API may be infrequently used push transactions. I recommend waiting until after the 01 March 2020 before using this on mainnet to ensure multiple people are using it, thus transactions sent to the blockstream node using txCast are not likely the same user.
Screenshot
Issues:
- tor integration may not be robust. Should connection be refreshed in a different way? (Used this)
- Not sure how well this deals with daylight saving time clock changes (time will jump) or how to best deal with this?
- Configured for testnet (Must remove /testnet from blockstream url for mainnet, I recommend waiting till 01 March 2020 as explained above)
- Using time delay to ensure new IP is used, could instead compare IP values.
- Could use .onion site rather than clearnet (Blockstream endpoint)
Future Work:
- Have this work with your own node if this is deemed advantageous (I expect that it is not given the use of tor here).
- Have options for broadcasting when fees drop below some user set threshold / not broadcasting when fees go too high.
- Have some check that transaction is confirmed, or at least seen by another node on the network (Use a second API).
- Have options for running this with a GUI
- Have this functionality added directly into wallets

Concepts

Reading 9 Probability Concepts
--------------------
Summary
- A random variable is a quantity whose outcome is uncertain.
- Probability is a number between 0 and 1 that describes the
chance that a stated event will occur.
- An event is a specified set of outcomes of a random variable.
- Mutually exclusive events can occur only one at a time.
Exhaustive events cover or contain all possible outcomes.
- The two defining properties of a probability are, first, that
0 ≤ P(E) ≤ 1 (where P(E) denotes the probability of an event E), and
second, that the sum of the probabilities of any set of mutually
exclusive and exhaustive events equals 1.
- A probability estimated from data as a relative frequency of
occurrence is an empirical probability. A probability drawing on
personal or subjective judgment is a subjective probability. A
probability obtained based on logical analysis is an a priori
probability.
- A probability of an event E, P(E), can be stated as odds for
E = P(E)/[1 − P(E)] or odds against E = [1 − P(E)]/P(E).
- Probabilities that are inconsistent create profit
opportunities, according to the Dutch Book Theorem.
- A probability of an event not conditioned on another event is
an unconditional probability. The unconditional probability of an
event A is denoted P(A). Unconditional probabilities are also called
marginal probabilities.
- A probability of an event given (conditioned on) another
event is a conditional probability. The probability of an event A
given an event B is denoted P(A | B).
- The probability of both A and B occurring is the joint
probability of A and B, denoted P(AB).
- P(A | B) = P(AB)/P(B), P(B) ≠ 0.
- The multiplication rule for probabilities is P(AB) = P(A |
B)P(B).
- The probability that A or B occurs, or both occur, is denoted
by P(A or B).
- The addition rule for probabilities is P(A or B) = P(A) +
P(B) − P(AB).
- When events are independent, the occurrence of one event does
not affect the probability of occurrence of the other event.
Otherwise, the events are dependent.
- The multiplication rule for independent events states that if
A and B are independent events, P(AB) = P(A)P(B). The rule
generalizes in similar fashion to more than two events.
- According to the total probability rule, if S1, S2, …, Sn are
mutually exclusive and exhaustive scenarios or events, then P(A) =
P(A | S1)P(S1) + P(A | S2)P(S2) + … + P(A | Sn)P(Sn).
- The expected value of a random variable is a
probability-weighted average of the possible outcomes of the random
variable. For a random variable X, the expected value of X is denoted
E(X).
- The total probability rule for expected value states that
E(X) = E(X | S1)P(S1) + E(X | S2)P(S2) + … + E(X | Sn)P(Sn), where
S1, S2, …, Sn are mutually exclusive and exhaustive scenarios or
events.
- The variance of a random variable is the expected value (the
probability-weighted average) of squared deviations from the random
variable’s expected value E(X): σ2(X) = E{[X − E(X)]2}, where σ2(X)
stands for the variance of X.
- Variance is a measure of dispersion about the mean.
Increasing variance indicates increasing dispersion. Variance is
measured in squared units of the original variable.
- Standard deviation is the positive square root of variance.
Standard deviation measures dispersion (as does variance), but it is
measured in the same units as the variable.
- Covariance is a measure of the co-movement between random
variables.
- The covariance between two random variables Ri and Rj is the
expected value of the cross-product of the deviations of the two
random variables from their respective means: Cov(Ri,Rj) = E{[Ri −
E(Ri)][Rj − E(Rj)]}. The covariance of a random variable with itself
is its own variance.
- Correlation is a number between −1 and +1 that measures the
co-movement (linear association) between two random variables:
ρ(Ri,Rj) = Cov(Ri,Rj)/[σ(Ri) σ(Rj)].
- To calculate the variance of return on a portfolio of n
assets, the inputs needed are the n expected returns on the
individual assets, n variances of return on the individual assets,
and n(n − 1)/2 distinct covariances.
- Portfolio variance of return is σ2(Rp)
= ∑∑ wiwjCov(Ri,Rj) .
- The calculation of covariance in a forward-looking sense
requires the specification of a joint probability function, which
gives the probability of joint occurrences of values of the two
random variables.
- When two random variables are independent, the joint
probability function is the product of the individual probability
functions of the random variables.
- Bayes’ formula is a method for updating probabilities based
on new information.
- Bayes’ formula is expressed as follows: Updated probability
of event given the new information = [(Probability of the new
information given event)/(Unconditional probability of the new
information)] × Prior probability of event.
- The multiplication rule of counting says, for example, that
if the first step in a process can be done in 10 ways, the second
step, given the first, can be done in 5 ways, and the third step,
given the first two, can be done in 7 ways, then the steps can be

Whew, it's been awhile. I actually have a few backlogged posts that I just haven't bothered to get to, so shame on me.

Giggity?

In honor of Madison Craft Beer Week 2014, I've decided to spend a little time getting back on track and there's some other exciting news coming once the new home is ready to be announced. In the meantime, though, we have a delightful Double IPA from Furthermore called Full Thicket. Full Thicket is a Wisconsin-hops-based Double IPA chock full of Cascade and Mt. Hood hops with enough malt to balance it out. The beer itself is delightfully well-balanced, and as a non-IPA fan, I still enjoyed it.
Prep/Cooking:

Yep. Looks like batter.
|
Full Thicket pours a smooth, light amber color with bountiful head and crisp, slightly sweet aroma. In batter form it's just as light as pretty much any other beer, but the taste was quite remarkable. The light sting of hops you usually get in the beer totally dropped off once it mated with the batter, and some of that latent malty sweetness that was being held back by the hops really came through. I was quite surprised at this batter, and it might be one of my favorite batters.

Wow, again I was quite surprised by these pancakes. They were kind of flat in texture and just as light in color as you would expect from the beer/batter, but the flavor really blew me away. Again, no real hop presence in the pancakes at all (at least not from a bitterness standpoint - I fully believe the flavor profile of the hops lead to this magnificent pancake), but the pancakes themselves were delightfully sweet with a hint of the wheaty goodness you tend to see in more traditional wheat beers. Maybe it's something about them local ingredients, but boy were these great.
The Ternary Scale:
Pancakes: 3 - definitely go get some Full Thicket (which should be widely available) and make these pancakes. Way better than the beer if you ask me.
Syrup: 1 - Honestly syrup kind of killed the subtleties and the delightful crisp sweetness of the pancakes. It just turned into a big sweet mess.

Having not done mushrooms in a little while a few of my friends and I decided that another trip was due. The original list of trippers was quite large, but dwindled after many people had second thoughts. That left six people with ounce of mushrooms. I had planned on taking only an eighth of an ounce but I let the moment get to me and ate roughly another gram.
After meditating in a big circle to direct our trip for a while I went upstairs to chat with my other non tripping friends. T+30 I felt the mushrooms starting to kick in and the excitement began. Every time I do mushrooms I become very flushed and this time was no exception, however I was becoming hot faster than normal.
Soon my friendís kitchen began melting in a fashion. The surface of the cabinets began sliding down and mixing with the floor which was quite insane. By now I was very happy and just couldn't stop talking (which is unusual because usually I am quiet).
The sun gradually set and we were going to go wander the open areas surrounding our houses. Before we left the house I picked up a blue plastic piece of something that I called the 'thing'. I can't quite describe it any other way than love. I was in love with this blue plastic thing. It would bend and change in my hand and I loved squeezing and chewing on it. Sanity as I exclaimed to one of my friends, had checked out.
Once I stepped outside I noticed that the lights were bright and beautiful as usual. The overcastted sky changed and rolled with colors. And shadows would dance in my peripheral. I was very very euphoric by now and my ego was sent through the roof. I felt as if there was no one cooler than myself and my other tripping buddies.
Upon arriving at the park it began raining. Feeling cold and wet I had this strange urge to break into some random persons house just to talk and chill.  So we began walking back to my friends house and became split up. By now sanity had completely checked out and I was speaking to myself, hearing and seeing things that just were not there.
When I arrived at the house I found one of my friends holding a very disturbing picture that he had drawn of someone getting shot. He was bleeding and speaking nonsense. Supposedly he had attacked one of my sober friends in an attempt to grab his knife.
I became very frightened and left.
 I was in a familiar neighborhood however I was very lost. I had the worst stomach cramp of my life and I felt lost and hopeless. I was completely emotionally driven there was no logic behind my thoughts. And they flew through my head at the speed of light. Everything around me was shifting and changing and I was seeing the world through a kaleidoscope.
When I closed my eyes I was the universe and the dawn of life. I understood the meaning of life. I knew it all. There was no reason to live. I wanted to end everything, just shoot myself and stop life because I realized that there ultimately was no point. Luckily I had no means of killing myself because I am 100% sure that I would have.
After I somehow found the way back to my friends house everyone was relieved to see me because I had been missing for the last hour or so. My stomach pain subsided a little after I puked my brains out.
I was lucky that night, I came out of it suicidal but for the most part ok, which is more than I can say for one of my other friends. (He drove away, hit two cars broke into a house started a fight got the cops called on him, bit an officer and was finally subdued by six cops). I remember the meaning of life and am happy to have found it. But I still don't know if it was worth it. My ego shot up like a rocket and crashed down even harder. I found the meaning of life and now I know what it is like to want to end my life. I also saw stuff that only insanity can create.

Football: Morata recalled to Spain squad, Ansu Fati and Ceballos miss out
MADRID: Spain have recalled Alvaro Morata for their Euro 2020 qualifiers against Malta and Romania after the striker scored five times in his last five games for Atletico Madrid.
Spain, who have already qualified for next year's championship, need to avoid defeat in one of their two remaining games in order to progress as Group F winners.
There was a maiden call up for Dani Olmo, however Barcelona's Ansu Fati and Arsenal's Dani Ceballos missed out.
Zagreb forward Olmo, who was a key part of the Spain Under-21 side that won this year’s European Championship, has impressed for the Croatian side in the Champions League this season.
The squad contains just five players from Spain’s so-called ‘big three’ sides - Real Madrid, Atletico Madrid and Barcelona.
Manchester City midfielder Rodri, who has not played since Oct. 22 due to a hamstring problem, is included while Barcelona’s Jordi Alba misses out through injury.
There is also no place for Barca team mate Fati.
The 17-year-old forward was granted Spanish citizenship in September before making his Under-21 debut last month. He is expected to be named by Luis de la Fuente in the U-21 squad later on Friday.
Spain host Malta on Nov. 15 and Romania three days later.
Spain squad in full:
Goalkeepers: David de Gea (Manchester United), Kepa Arrizabalaga (Chelsea), Pau Lopez (Roma)
Defenders: Jose Gaya (Valencia), Dani Carvajal (Real Madrid), Raul Albiol (Napoli), Inigo Martinez (Athletic), Sergio Ramos (Real Madrid), Juan Bernat (PSG), Pau Torres (Villarreal), Jesus Navas (Sevilla)
Midfielders: Sergio Busquets (Barcelona), Rodri (Manchester City), Thiago (Bayern), Saul Niguez (Atletico), Fabian Ruiz (Napoli), Santi Cazorla (Villarreal)
Forwards: Rodrigo (Valencia), Gerard Moreno (Villarreal), Paco Alcacer (Borussia Dortmund), Mikel Oyarzabal (Real Sociedad), Alvaro Morata (Atletico), Dani Olmo (Dinamo Zagreb)

Number of previous iteration steps
Returns: K : ndarray, size (nc)
Final value of the K-factors
beta : float
Fraction of gas or liquid (–)
xi : ndarray, size(2, nc)
Mole fraction of each component in the mixture. Row 1 gives the values for the gas phase and Row 2 gives the values for the liquid phase (–)
exit_flag : int
Flag indicating how the solution finished: 1: converged in the allowable number of iterations, 0: did not converge and did not find any indication that it might be single phase, and -1: did not converge, but it looks like it might be single phase.
steps : int

Notes
The max_iter parameter controls how many steps of successive iteration are performed. If set to None, the iteration will continue until the tolerance criteria are reached.


To send a combo leg limit order, create multiple Leg
objects to represent the legs of the combo order, then call the ComboLegLimitOrder
method. The legs must each target a unique contract. At least one leg must have a positive quantity and at least one leg must have a negative quantity. If you don't have sufficient capital for the order, it's rejected.
foreach (var kvp in slice.OptionChains) { // Select contracts var contracts = kvp.Value.Contracts.Values.ToList(); if (contracts.Count < 2) { return; } // Create order legs var legs = new List<Leg>() { Leg.Create(contracts[0].Symbol, 1, contracts[0].LastPrice * 0.98m), Leg.Create(contracts[1].Symbol, -1, contracts[1].LastPrice * 1.02m) }; // Place order ComboLegLimitOrder(legs, 1); }
for canonical_symbol, chain in slice.OptionChains.items(): # Select contracts contracts = [c for c in chain][:2] if len(contracts) < 2: return # Create order legs legs = [] quantities = [1, -1] factors = [0.98, 1.02] for i, contract in enumerate(contracts): legs.append(Leg.Create(contract.Symbol, quantities[i], contract.LastPrice * factors[i])) # Place order self.ComboLegLimitOrder(legs, 1)
The quantity of the legs sets the ratio of the leg orders while the quantity argument of the ComboLegLimitOrder
method sets the combo order size and acts as a global multiplier. In the preceding example, if we set the global multiplier to two, then the algorithm buys two units of the first contract and sells two units of the second contract. The quantity also sets the order direction of the combo limit order, which affects how the fill model fills the order.
You can also provide a tag and order properties to the ComboLegLimitOrder
method.
ComboLegLimitOrder(legs, quantity, tag: tag, orderProperties: orderProperties);
self.ComboLegLimitOrder(legs, quantity, tag=tag, orderProperties=order_properties)

Next: Constant Variables, Previous: Lexical Variables, Up: The Evaluation Model
A variable is a dynamic variable if one of the following conditions hold:
It is locally declared or globally proclaimed special.
It occurs textually within a form that creates a dynamic binding for a variable of the same name, and the binding is not shadowed_2 by a form that creates a lexical binding of the same variable name.
A dynamic variable can be referenced at any time in any program; there is no textual limitation on references to dynamic variables. At any given time, all dynamic variables with a given name refer to exactly one binding, either in the dynamic environment or in the global environment.
The value part of the binding for a dynamic variable might be empty; in this case, the dynamic variable is said to have no value, or to be unbound. A dynamic variable can be made unbound by using makunbound.
The effect of binding a dynamic variable is to create a new binding to which all references to that dynamic variable in any program refer for the duration of the evaluation of the form that creates the dynamic binding.
A dynamic variable can be referenced outside the dynamic extent of a form that binds it. Such a variable is sometimes called a "global variable" but is still in all respects just a dynamic variable whose binding happens to exist in the global environment rather than in some dynamic environment.
A dynamic variable is unbound unless and until explicitly assigned a value, except for those variables whose initial value is defined in this specification or by an implementation.

A common approach following metagenome assembly is binning, a process by which assembled contigs are collected into groups or ‘bins’ that might then be assigned some taxonomic affiliation. There are many different tools that can be used for binning (see CAMI review for more details). Here, we will be using MaxBin and MetaBAT, which are both user friendly and highly cited. To use these binners, we will first need to map our data against the assembled metagenome using bwa and then estimate relative abundances by contig. We will then inspect the bins generated by MaxBin and MetaBAT using VizBin.
MaxBin
cd
curl https://downloads.jbei.org/data/microbial_communities/MaxBin/getfile.php?MaxBin-2.2.2.tar.gz > MaxBin-2.2.2.tar.gz
tar xzvf MaxBin-2.2.2.tar.gz
cd MaxBin-2.2.2
cd src
make
cd ..
./autobuild_auxiliary
export PATH=$PATH:~/MaxBin-2.2.2
MetaBAT
cd
curl -L https://bitbucket.org/berkeleylab/metabat/downloads/metabat-static-binary-linux-x64_v0.32.4.tar.gz > metabatv0.32.4.tar.gz
tar xvf metabatv0.32.4.tar.gz
Time to finally run the Binners! Note: MaxBin can take a lot of time to run and bin your metagenome. As this is a workshop, we are doing three things that sacrifice quality for speed.
Q. Why is the read counts per contigs not an accurate number?
cd ~/mapping
for i in *sorted.bam
do
samtools idxstats $i > $i.idxstats
cut -f1,3 $i.idxstats > $i.counts
done
–
Maxbin uses read coverage & tetranucleotide frequencies for each contig, and marker gene counts for each bin
First, we will get a list of the count files that we have to pass to MaxBin
mkdir ~/mapping/binning
cd ~/mapping/binning
ls ../*counts > abundance.list
Now, on to the actual binning
run_MaxBin.pl -contig ../subset_assembly.fa -abund_list abundance.list -max_iteration 5 -out mbin
This will generate a series of files. Take a look at the files generated. In particular you should see a series of *.fasta files preceeded by numbers. These are the different genome bins predicted by MaxBin.
Take a look at the mbin.summary file. What is shown?
Now, we are going to generate a concatenated file that contains all of our genome bins put together. We will change the fasta header name to include the bin number so that we can tell them apart later.
for file in mbin.*.fasta
do
num=${file//[!0-9]/}
sed -e "/^>/ s/$/ ${num}/" mbin.$num.fasta >> maxbin_binned.concat.fasta
done
And finally make an annotation file for visualization
echo label > maxbin_annotation.list
grep ">" maxbin_binned.concat.fasta |cut -f2 -d ' '>> maxbin_annotation.list
–
MetaBAT uses read coverage, coverage variance, & tetranucleotide frequencies for each contig. This is done with a custom script
cd ~/mapping
~/metabat/jgi_summarize_bam_contig_depths --outputDepth depth_var.txt *sorted.bam
Setup another “binning” directory for this tool’s results
mkdir ~/mapping/binning_metabat
cd ~/mapping/binning_metabat
Run MetaBAT script
Note that we are outputting info to a logfile
~/metabat/metabat -i ../subset_assembly.fa -a ../depth_var.txt --verysensitive -o metabat -v > log.txt
Make the .fasta file of all binned sequences
for file in metabat.*.fa
do
num=${file//[!0-9]/}
sed -e "/^>/ s/$/ ${num}/" metabat.$num.fa >> metabat_binned.concat.fasta
done
Make an annotation file of the bin numbers for annotation in VizBin
echo label > metabat_annotation.list
grep ">" metabat_binned.concat.fasta |cut -f2 -d ' '>> metabat_annotation.list
Now that we have our binned data from both MetaBAT and MaxBin there are several different things we can do. One thing we might want to do is check the quality of the binning– a useful tool for this is CheckM. Today, for the sake of time, we will visualize the bins that we just generated using VizBin.
First, install VizBin::
cd
sudo apt-get install libatlas3-base libopenblas-base default-jre
curl -L https://github.com/claczny/VizBin/blob/master/VizBin-dist.jar?raw=true > VizBin-dist.jar
VizBin can run in OSX or Linux but is very hard to install on Windows. To simplify things we are going to run VizBin in the desktop emulator through JetStream (which is ... a bit clunky). So, go back to the Jetstream and open up the web desktop simulator.
Open the terminal through the desktop simulator and open VizBin:
java -jar VizBin-dist.jar
This should prompt VizBin to open in another window. First we will look at the output of the MaxBin assembly. Click the choose button to open file browser to navigate to the binning folder (~/mapping/binning
). There you will find the concatenated binned fasta file (maxbin_binned.concat.fasta

Typical examples are:
"True"
"False"
"Left" (laterality)
"Right" (ditto)
"High"
"Low".
Obviously, there are sets from which selection may be made. This should be governed by constraining
selection to one out of a set of species categories within a single Classification Element.

async search and index

I am working with a really big project, with about 70 000+ files and CommandT feels really slow.
Does command-t do async file search and indexing?
Thanks!

It's not doing any indexing, as such, beyond reading the file hierarchy the first time it is displayed and caching it in memory. I've spent quite a bit of time thinking about data structures that would allow me to trade some space for time, doing some up-front processing in order to deliver faster searches subsequently. To date, I haven't found anything viable.
Back in ancient history, Command-T used to use a linear algorithm for scoring and matching. In mid-2010 it switched to an algorithm which is quadratic in the worst case, but tends to give much more intuitive results (see issue #1598).
This still yields pretty good performance at around 20k files, but I am not surprised that it is starting to suffer at 70k+.
We could add code that allowed you to fall back to the faster-but-less-accurate scoring method. That might make things more usable, although ironically, it's precisely on larger projects that you want the more intuitive matching to help you get to the files you want without having to perform too many keystrokes.

Thanks for your quick reply. I understand it's reading the file hierarchy only - what I meant is: is that done in a separate thread? Would it be possible for the ruby script to have two threads - one that works with vim, updates UI and so on, and the other thread that receives requests for file lists, matching, sorting/scoring, etc. This way the UI would not block at all, we would have results "instantly". You could send smaller sets of results to the UI, in batches, as the file hierarchy reading goes further.
I really like how fast Sublime Text 2 is - it works very well with 70k files.
I did an investigation on my Linux machine: even a finely tuned |find| command that skips .hg/.git folders and .bak files and other binary file types... I still have to wait a couple of seconds before it's done. I don't see how Command-T could ever be "instant" without some kind of threading / async behavior.
I have also tried Fuzzy Finder and CtrlP. Command-T is the nicest and most intuitive of all. Still, I'm forced to use FuF because it doesn't do deep folder hierarchy searching, and that makes it fast - with the cost of having to type more (folder names, not only file names).
Keep up the good work!

Right. Vim itself is single-threaded, so while it is possible to do threading in a plug-in (ie. something like Command-T, written in Ruby, or something in Python) it does feel a bit risky, as it may interact poorly with code in Vim which is operating under the assumption that it is the only thing running.
I actually think the way to get Command-T to be responsive with that number of files isn't threading; it's just going back to the much-faster-but-not-quite-as-good linear scoring algorithm of old. A configuration option, perhaps.

myExpr
against a text myString
one should first create a Pattern object:
Pattern p=new Pattern(myExpr);
then obtain a Matcher object:
Matcher matcher=p.matcher(myText);
The latter is an automaton that actually performs a search. find()
method we would find '123' only.

Amanitas - A. muscaria (10x extract), Syrian Rue & Cannabis
Having a free and rather dull evening I thought I would try a gram of 10x Amanita extract I bought a while back. I dosed on some syrian rue extract 20 minutes before hand as it may enhance the effects. After dosing withe extract I waited. And waited. nothing happened.
I ran a bath a rolled a strong joint hoping it would boost any amanita effects (they are meant to go very well together). nothing though. I was spaced out, yes, but it was due to the syrian rue and strong joint combined.
Picking and preparing ones from the wild are my best bet (trust me, they do the trick).

Exceptions Demo 1
Controller Exception Handling
Summary
- Demo running with profiles: profiles
- Key classes:
ExceptionHandlingController
.
- See for more details.
Details
The exceptions below are thrown and handled within the same Controller
using its own
@ExceptionHandler
methods. The controller is
demo1.web.ExceptionHandlingController
.
To fully understand this demo, review the output in the server
(console) log as you click the links below.
The behavior of this demo is the same as Demo 2
- just implemented differently.
Demo
- Throw OrderNotFoundException
- should generate a 404 (in the Spring Boot error page).
- Throw DataIntegrityViolationException
- should generate a 409 (in the Spring Boot error page).
- Throw SQLException -
should return a specific database-error page.
- Throw DataAccessException
- should also return the database-error page. Demonstrates catching
multiple exceptions with one handler.
- Throw SupportInfoException
- should generate a support oriented error page with hidden
stack-trace hidden in the page source. Whether this is a good idea,
is debatable! but it shows how to add extra information into the
model for the exception view to use.
