the current Covid situation in Nepal
Covid Alliance for Nepal is an all-volunteer crisis-response group of individuals and organisations who have come together to tackle the current Covid situation in Nepal. The alliance’s guiding principle is around collaboration, and creating immediate and sustainable impact whereby decisions are driven by science, data and expertise.
push actors with the power to (re)allocate their surplus vaccine doses, ensuring vulnerable communities in Nepal receive vaccines.
blueprint integrating the MoHP’s guidelines and recommendations from doctors along with providing resource support to set-up such centers.
providing medical support staffed by trained nurses and medical officers for both covid and non covid related issues.
scripted and disseminated multiple Public Service Announcements (PSAs) across 23 FM radio stations in several local languages.
provides information on oxygen resources, procures oxygen related equipment (e.g. cylinders, concentrators and plants), coordinates refill and circulation.
for frontline medical workers, hotline staff, and isolation center staff in partnership with HAPSA-Nepal and Brown University & Project Hope.
working on a welfare scheme for frontline workers who may need medical treatment in the case of contracting Covid on the job.
working with government schools, wards and grassroot organisations to provide food assistance in various locations around the valley.
running sessions on managing mental and emotional health along with support networks and sharing teleconsultation counselling services.
Nepal currently has the highest rate of reproduction of COVID-19 in the world. In some places, test results - for those who take them - are returning with positivity rates of higher than 40%. By mid-July, at the current rate of reproduction and infection, Nepal could be looking at 800,000 Covid patients.
Our public health and medical infrastructure is strained and insufficient even in ordinary times, but the dearth of trained doctors, hospital access, ICUs, and even basic materials like supplementary oxygen is one that we feel especially acutely now. The “low” mortality rates for Covid are in contexts with medical infrastructure and supplementary oxygen that can respond to patient need, and avert death. We are already looking at a possibility of 10 critically ill patients for every hospital bed, and where supplies of otherwise-basic medication, and oxygen, are already running very low, and not accessible in other places. From the strict lockdown of 2020, Nepalis have been facing lockdown fatigue -- but at entirely too dangerous a time.
Breaking the cycle of nation-wide lockdowns can only take place with vaccination and mass public health advocacy. While the situation in terms of infection and transmission is sobering, we are committed to working with each other, and other groups, to mobilize what we can to respond to peoples’ needs.

When requested, a $(ref:windows.Window)
will contain an array of $(ref:tabs.Tab)
objects.
You must declare the "tabs"
permission in your
manifest if you require access to the
$(ref:tabs.Tab.url url)
,
$(ref:tabs.Tab.title title)
, or
$(ref:tabs.Tab.favIconUrl favIconUrl)
properties of
$(ref:tabs.Tab)
.
For example:
{ "name": "My extension", ... "permissions": ["tabs"], ... }
Many functions in the extension system take an optional windowId parameter, which defaults to the current window.
The current window is the window that contains the code that is currently executing. It's important to realize that this can be different from the topmost or focused window.
For example, say an extension creates a few tabs or windows from a single HTML file, and that the HTML file contains a call to $(ref:tabs.query). The current window is the window that contains the page that made the call, no matter what the topmost window is.
In the case of the event page, the value of the current window falls back to the last active window. Under some circumstances, there may be no current window for background pages.
You can find simple examples of using the windows module in the
examples/api/windows
directory.
Another example is in the
tabs_api.html file
of the
inspector
example.

Mr Bewg's Reference
Dear Mr Corncrake
Re: Mr B Bewg, 164 Dismal Terrace, Hoon
Thank you for your letter of 14 July regarding the above-named. I am happy to provide him with a reference.
I have known Mr Bewg for ten years, ever since he took up the position of scrivener, dogsbody and wretch in my vast gloomy factory perched on the hillside next to the lunatic asylum. At the time I engaged Mr Bewg I suspected that he had some past connection with the latter institution, and in the decade since I have had no reason to revise my opinion.
You ask me to comment on my impression of Mr Bewg's "suitability for the job". Forgive me if I find this difficult. I do not wish to do violence to our mother tongue, but to use the word "suitability" in conjunction with Mr Bewg is to mock the Queen's English. Indeed, it is to make a mockery of Sense itself.
My problems with Mr Bewg began on his very first morning in my employ. To settle him in, I had instructed him to carry out a menial task, removing bits of goo from the interior walls of a vat. To facilitate his progress, he was supplied with a variety of tools including a pencil sharpener, a pin-cushion, and a decidedly ferocious blowtorch. No sooner had I turned my back than Mr Bewg became embroiled in a tussle with my pet panther, which - crazed with hunger - managed to slip its leash and embed its razor-sharp fangs in his left leg. For this impertinence I had no option but to dock Mr Bewg his first month's wages.
It was not a good start, but I had had many a ne'er-do-well working for me in the past, and believed that I could yet mould Mr Bewg into a marginally less repellent specimen of human dregs. To this end, I assigned him to work in the filthiest, dankest wing of the factory, where he was expected to spend all day dragging sacks full of huge iron lumps backwards and forwards through infested tunnels for no apparent purpose. So ineptly did Mr Bewg execute his duties that I was forced to withhold his pay for a further year. I wrung my hands with frustration, but the man was impossible. Given a simple task, he was utterly incapable of completing it with the requisite speed, good humour and fawning obeisance that one expects.
To give just one example: Mr Bewg failed to budge one particularly heavy sack (containing a score of medium-sized anvils) a single inch, despite being given all of four and a half minutes to drag it eight hundred yards along a stinking tunnel in which small bonfires of sulphur had been ignited only moments before. I set a wolfhound yapping at his heels, but to no avail. The man was purely and simply workshy. But I am a fair man, and I had no wish to consign him irrevocably into the underclass of the unemployed and unemployable.
Instead, I agreed with Mr Bewg that he could embark upon a training scheme. In return for a modest fee to be paid to me daily, in cash, I offered to provide him with a comprehensive course of training in a multiplicity of disciplines, both within the factory and in the adjoining administrative hellhole. In the first week alone, we covered a huge range of skills: licking my boots till they gleamed, prostrating himself on his stomach whenever I came within two hundred yards of him, and slobbering with happiness at the mere mention of my name.
At this stage in what can only roughly be called his "career", Mr Bewg crawled into my palatial office one day to request my assistance with a personal matter. Tempted though I was to have him savaged by giant badgers, I reclined in my unbelievably comfortable executive armchair and heard him out. He confessed that he was in some financial difficulties and begged me to help. Sipping my glass of ruinously expensive wine, I delivered a stern lecture on the virtues of thrift and idly beat him about the skull with a copy of Self-Help. I admitted that I was in a position to pay his paltry debts a billionfold if I wished to, but that such a course of action would not in the long run be of the slightest benefit to him. I then advised him that he could earn a few extra pounds by selling various of his bodily organs and thus better his financial situation while basking in the knowledge that he was being self-reliant rather than coming cap-in-hand to his employer. To prove my point, I offered to buy one of his kidneys and two pints of his blood on the spot, for which I would pay him fourpence. As the bulk of his debts were monies owed to me, I generously docked the fourpence from his account. In this way, I was able to relieve him of the responsibility of handling any cash himself, and thereby falling prey to the inevitable temptation to fritter the money away on food, clothing, and medicine. Only after this transaction had taken place did I set the giant badgers onto him.
Not long after this incident, Mr Bewg announced that he had found himself another job, and wished to terminate his contract of employment. If his inane burbling was to be believed, he had been offered the post of Assistant Slave at a charnel-house, the main duties being to crawl on his hands and knees in foul pits of ordure. While I listened patiently, he explained that he felt this post would give him opportunities undreamed of in his current position, and that he was prepared to take a cut in salary in order to take up the offer. Poking at him with a stick, I nodded my consent. I had no wish to stand in his way. My only concern was that he would have the common decency to fulfil the terms and conditions of his contract before setting off for greener pastures. I then reminded him of the form he had signed on his first day at the factory, the main clauses of which stated that in order to leave, he was required to give forty years notice and to repay every single penny of his salary since day one. To my surprise, Mr Bewg - who moments before had been adamant that he wanted to leave - now said that he would like a few more days to consider the matter. Once again I nodded my assent, then summoned fourteen of my assistants, who bundled Mr Bewg out of my office and set him to work on his latest task, which was to lie face down in a muddy ditch while a herd of demented bison charged over him.
In view of the above, I must admit that I cannot in truth recommend Mr Bewg to you. His work is shoddy, his attendance and punctuality leave much to be desired, and I have the gravest doubts about his character. His sickness record is thoroughly unsatisfactory, and I have been put in the uncomfortable position of having to threaten various members of the medical profession with monstrous violence after they had the temerity to issue Mr Bewg with certificates recommending that he stay off work for half an hour. However, should you decide to ignore my warnings and offer a job to Mr Bewg, I will have great pleasure in delivering what is left of him to your premises upon the expiry of his notice period in forty years time.
Yours sincerely

socketpair - create a pair of connected sockets
#include <sys/types.h> /* See NOTES */
#include <sys/socket.h>
int socketpair(int domain, int
type, int protocol, int
sv[2]);
The socketpair() call creates an unnamed pair of connected sockets in the
specified domain, of the specified type, and using the
optionally specified protocol. For further details of these arguments,
see socket(2).
The file descriptors used in referencing the new sockets are
returned in sv[0] and sv[1]. The two sockets are
indistinguishable.
On success, zero is returned. On error, -1 is returned, errno is set
appropriately, and sv is left unchanged
On Linux (and other systems), socketpair() does not modify
sv on failure. A requirement standardizing this behavior was added in
POSIX.1-2016.
- EAFNOSUPPORT
- The specified address family is not supported on this machine.
- EFAULT
- The address sv does not specify a valid part of the process address
space.
- EMFILE
- The per-process limit on the number of open file descriptors has been
reached.
- ENFILE
- The system-wide limit on the total number of open files has been
reached.
- EOPNOTSUPP
- The specified protocol does not support creation of socket pairs.
- EPROTONOSUPPORT
- The specified protocol is not supported on this machine.
POSIX.1-2001, POSIX.1-2008, 4.4BSD. socketpair() first appeared in
4.2BSD. It is generally portable to/from non-BSD systems supporting clones of
the BSD socket layer (including System V variants).
On Linux, the only supported domains for this call are AF_UNIX (or
synonymously, AF_LOCAL) and AF_TIPC (since Linux 4.12).
Since Linux 2.6.27, socketpair() supports the
SOCK_NONBLOCK and SOCK_CLOEXEC flags in the type
argument, as described in socket(2).
POSIX.1 does not require the inclusion of
<sys/types.h>, and this header file is not required on Linux.
However, some historical (BSD) implementations required this header file,
and portable applications are probably wise to include it.

The Truman Show 1998 Dir: Peter Weir 7/10 I went into this movie with a lot of expectations. While I'm not a huge fan of Jim Carrey, the premise sounded extremely fascinating, and the word of mouth had been glowing. Sadly, while the Truman Show is 'pretty good', it never quite becomes the masterpiece that it was meant to be. For those of you tuning in late, the film stars Jim Carrey as Truman Burbank, a man whose entire life is really a television show. His wife, his friends, etc. are all actors. His town is a set. So on, so on. Eventually he begins to discover what's going on. The problem of the film lies mostly in its tone. While for the most part it is a somewhat serious film, constant bits of humor are thrown in. Sometimes this helps the film, as when we laugh at Truman's life. But other times, such as when we see the reactions of a viewer to Truman's stormy sea voyage, it destroys any tension. This movie doesn't quite know what it wants to be. The ending truly underscores this fact. While it would be a marvelous ending for a satire about our society and our obsession with television, which this movie does court becoming, it doesn't fit the film we have seen, which is really about Truman. The Truman Show could have been a brilliant satire about society, or it could have been a moving character study/Twilight Zone episode. Instead, by not choosing a direction, it becomes neither and finally settles on pleasant mediocrity.

Now we have learned all the theories about MCMC. But how we can use it in practical? Especially how we can use it to solve Bayesian Inference problems?
1. Intuition
MCMC is a sampling technique but in most of the places it will be used for parameter estimation. How could this two connect with each other?
Actually that relates to the key concept from Bayesian framework: We treat unknown parameters as random, and they also follow some distributions. After knowing this, the connection is smoother: MCMC can be used to sample data from the parameters' distribution and then make an estimation. More specifically, this distribution is parameter's posterior distribution.
Here is the logic flow for one common scenario of using MCMC:
- We have gathered real life data from one distribution but we don’t know the parameter value of this distribution. So we want to estimate these parameters (The distribution is explicit even though we don't know the parameter)
- To estimate it, we want to sample data from these parameters' posterior distribution
- To sample from posterior equals to sample from unnormalized posterior (cause the evidence will be neutralized in MCMC)
- Using Bayes formula, to sample from unnormalized posterior we need to provide a prior
- Using MH or Gibbs sampling, we then need to either come up with a proposal distribution or provide the conditional distribution
2. Example - Estimation of Correlation
Suppose we are interested in modeling the correlation \(\rho\) between two streams of observations \((x_1,...,x_n)\) and \((y_1,...,y_n)\). And suppose we know the observations given the correlation belongs to Bivarite Gaussian distribution: \[p(x,y|\rho) \sim Normal(\mu,\Sigma)\] where \(\mu = [\mu_x,\mu_y]\) and \(\Sigma = \left(\begin{array}{cc} \sigma_{xx}&\rho \\ \rho & \sigma_{yy} \end{array}\right)\). For simplicity, we assume that we know \(\mu_x,\mu_y=0\) and \(\sigma_{xx},\sigma_{yy}=1\).
In this case, the likelihood function takes the following form: \[p(x,y|\rho) = \prod_{i=1}^{N}\frac{1}{2\pi\sqrt{1-\rho^2}}exp\{-\frac{1}{2(1-\rho^2)}[x_i^2-2\rho x_i y_i +y_i^2] \}\]
Next we need to specify a prior distribution for parameter \(\rho\). Suppose we also choose from normal distribution: \[p(\rho) \sim Normal(0,1)\]
Then using Bayes rule, we write the unnormalized posterior distribution for the correlation parameter \(\rho\) in the following ways: \[p(\rho|x,y) \propto \frac{1}{\sqrt{2\pi}}exp\{-\frac{\rho^2}{2} \}\prod_{i=1}^{N}\frac{1}{2\pi\sqrt{1-\rho^2}}exp\{-\frac{1}{2(1-\rho^2)}[x_i^2-2\rho x_i y_i +y_i^2] \}\]
Finally we try to find a symmetric proposal distribution. Here we choose a Uniform distribution centered at the current value of \(\rho\). \[\rho \sim Uniform(\rho^{i-1}-0.1,\rho^{i-1}+0.1)\]
Then the acceptance rate can be obtained using: \[\alpha(\rho^{i}|\rho^{i-1})= min\{1, \frac{p(\rho^i)}{p(\rho^{i-1})}\}\]
We are good to go for using Metropolis-Hastings Sampling, Python script can be found here: Notebook for MH-Sampling
Here are the results:
- Top image is what the real random data looks like which has the true correlation 0.5
- Middle row is the trace plot of \(\rho\) after burn-in, we can see the chain is almost stationary
- Bottom image plots the posterior distribution of \(\rho\) sampled from MCMC. The mean of this distribution is 0.52. So MCMC does give us a very good estimation.
3. Usage of Pymc3
For last example I didn't use specific MCMC package. Actually Pymc3
is a very good python package to perform MCMC and deal with other Bayesian Inference problem. I would like to use it more and get back to here later.

Browsing the Database using the Observing Log Web Application
The Observing Log application provides three different views of completed observations
- The Plan View is the view of observations taken on a single night in the order they are acquired. In Plan View
there is one line for each unique configuration of the instrument used to acquire data.
- Observation View is the view of a single observation showing all the observation's datasets. The configuration
of the system for each dataset is completely shown.
- Program View shows all the observations in a Science Program. As with Plan View, the observations are shown as
one line for each unique configuration.
Using the Action links
- Selecting the obs link in Program View or Plan View shows the Observation View for a row.
- Selecting the prog link in Plan View or Observation View shows the Science Program View that a row.
- Selecting the plan link in Program View or Observation View shows the Plan View for the specific row.


Warching TV
问题描述 :
Lemon likes warching TV very much. When winter holiday comes, it is a good time, isn’t it. There are lots of TV program listed on the paper. Every TV program has its start time ,end time, and the happiness value that will add Lemon’s happiness and it depends on Lemon’s taste.
输入:
There are many test cases. Please process to end of file. Each test case starts with one integer N (1 <= N <= 100000) which indicates the size of the list of the TV program. Then N lines follow, each line contains three integers s, e and v. s, e indicate that the TV program is during [s, e](1 <= s <= e <= 1000000). v indicates that after warching the TV program will add Lemon v happyiness(1 <= v <= 1000). Once Lemon choose a TV program, he must finish warching the TV program.

题意：求任意年的11月份的第四个星期日的具体日期（感恩节）的日期。
方法一：直接模拟，999年11月1日是星期五（可以试出来）。
#include <iostream> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <math.h> #include <vector> #include <queue> #include <algorithm> using namespace std; int main() { #ifndef ONLINE_JUDGE freopen("in.txt","r",stdin); #endif int a[10005]; int t = 5; for(int i=1000; i<=9999; i++) { if(i%400 == 0 || (i%4 == 0 && i%100!=0)) { t+=2; } else { t++; } t%=7; a[i] = t; } int n; while(scanf(" %d",&n)!=EOF) { int x=a[n]-4; printf("%d-11-",n); if(x<=0) { printf("%d\n",3*7-x+1); } else { printf("%d\n",4*7-x+1); } } return 0; }
方法二:蔡勒公式
公式：
蔡勒公式：
W =( [C/4] – 2C + y + [y/4] + [13×(M+1) / 5] + d – 1) % 7;
W是星期几，C是世纪数减一，y是年份后两位，M是月份（从3月开始，1月和2月要按上一年的13月和 14月来算，这时C和y均按上一年取值），d是日数。
出W的值，再除以7，余几就是星期几，余数为0，则是星期天。
注意：[...]表示只取整数部分
注意：公式中如计算得出负数，不能按习惯的余数的概念求余数，只能按数论中的余数的定义求余。为了方便计算，我们可以给它加上一个7的整数倍，使
变为一个正数，比如加上7、14、21、28等，得到一个整数后， 再除以7，余几，说明这一天是星期几。
#include <cstdio> int w,c,y,m,d; int main() { int x; m=11; while (scanf("%d",&y)==1) { d=1; printf("%d-11-",y); c=y/100; y%=100; w=(c>>2)-(c<<1)+y+(y>>2)+13*(m+1)/5+d-1; while (w<0) w+=7; w%=7; x=4-w; if (x<0) x+=7; d+=x+21; printf("%d\n",d); } return 0; }

如何解决overload的问题呢？
您没有考虑 树的根节点是负数的情况， 若树的根节点是个很大的负数，那么就要考虑过不过另外一边子树了
这一题的代码这样提交时错误的~少考虑了很多情况
第63行是不是漏了 return 1 + dis_right; ?
正在练习，很有帮助
有限自动机在ACM中是必须掌握的算法，实际上在面试当中几乎不可能让你单独的去实现这个算法，如果有题目要用到有限自动机来降低时间复杂度，那么这种面试题应该属于很难的级别了。
The site You have write is very nicely prepared and quite insightful thanks for nice posta?|
非常好，初学者就应该先理解递归
后面的是python代码啊
这个问题别太纠结了，不同的编译器结果不一
这个还不错
这个差别应该不会太大，或许编辑器就自动优化成内联函数了
因为是要把从字符串s的start位到当前位在hash中重置，修改提交后能accept，但是不修改居然也能accept
正在练习，很有帮助

--- layout: post title: Spam and apologies date: 2004-07-01 00:00:00 category: personal ---
I've been hit by a lot of comment spam recently. A *lot* of it.
At first, I diligently deleted it; but massive quantities over a period when I was on holiday got through.
Then I changed my mind; the reason this spam is here is that it improves someones' Google ranking, I thought. If this is the case, leaving the spam around devalues Google - and makes comment spam their problem, I thought. They'll change the way they rank pages so that comment spam is no longer worth doing, and it'll go away, I thought.
Well, that hasn't happened. Maybe it will happen one day, but it hasn't yet. And the stuff is flooding in, and is increasingly offensive - to the point where I'm feeling that leaving it up here is Really Rather Wrong.
There isn't a quick solution to this that I'm aware of, and right now time is tight. I plan to move to a new installation of MovableType, bringing together the several weblogs that are hosted on our server (and a new one that is being built right now), and will more at ways of rejecting spam then, but that will take a few weeks.
So, comments are disabled (in a pretty crude fashion). Which is a real shame because one of the things *I* get from this weblog is feedback from a group of smart folks that come here. If you want to comment on any post (positively or negatively) whilst comments are disabled, please email me and I'll add your text to the foot of the relevant post.
Hopefully normal service will be resumed soon...

Juno <IP_ADDRESS> is a moderate update.
-
Simplified the {@link oaj.serializer.Serializer} and {@link oaj.parser.Parser} class hierarchies.
This reverses a previous change that added a bunch of interfaces in these APIs (and subsequently required compiling with Java 7 to get around a compiler bug).
The new class hierarchy is much simpler to understand.
-
Added
XMLGregorianCalendarSwap to convert these to ISO8601 strings during serialization, and vice versa during parsing.
-
Added a strict mode to {@link oaj.json.JsonParser}.
-
Added default {@link oaj.json.JsonParser#DEFAULT_STRICT} parser.


Goodsmile's New Splatoon Figmas Are Fresher Than Your Bed Linen On Laundry Day
Judd and Li'l Judd are included, too!
by Damien McFerranJapanese toymaker figma has announced some new Splatoon figures for 2020, and they're looking insanely good.
A new 'DX' double pack – which contains two Inkling Boys, Judd and Li'l Judd and a whole bunch of accessories – is available for pre-order now. This pack comes with Splattershot guns, a Splatterscope, Squidfin Hook Cans, a Painter's Mask, Retro Specs, ink splat effects, flags for Judd and Li'l Judd and stands to pose the figures on. Phew! The only catch is that they're not out until June next year.
If that's a little too rich for your blood, then you can pick up the Inkling Boy or Inkling Girl on their own for a lower price. The latter is available now, while the former launches alongside the double pack in June 2020.
The double pack will cost ¥13,800, while the single Inkling Boy is ¥6,800. An existing DX double-pack with two Inkling Girls is also available now. We're drowning in Splatoon figmas, and we love it.
If you place your order using the links below and enter the discount code NLIFE at checkout, you'll get 5% off the total.

迁移 Kotlin 多平台项目到 1.4.0
Kotlin 1.4.0 comes with lots of features and improvements in the tooling for multiplatform programming. Some of them just work out of the box on existing projects, and some require additional configuration steps. This guide will help you migrate your multiplatform projects to 1.4.0 and get the benefits of all its new features.
对于多平台项目作者
更新 Gradle
Starting with 1.4.0, Kotlin multiplatform projects require Gradle 6.0 or later. Make sure that your projects use the proper version of Gradle and upgrade it if needed. See the Gradle documentation for non-Kotlin-specific migration instructions.
简化构建配置
Gradle module metadata provides rich publishing and dependency resolution features that are used in Kotlin Multiplatform Projects. In Gradle 6.0 and above, module metadata is used in dependency resolution and included in publications by default. Thus, once you update to Gradle 6.0, you can remove enableFeaturePreview("GRADLE_METADATA")
from the project’s settings.gradle
file.
If you use libraries published with metadata, you only have to specify dependencies on them only once in the shared source set, as opposed to specifying dependencies on different variants of the same library in the shared and platform-specific source sets prior to 1.4.0.
Starting from 1.4.0, you also no longer need to declare a dependency on stdlib
in each source set manually – it will now be added by default. The version of the automatically added standard library will be the same as the version of the Kotlin Gradle plugin, since they have the same versioning.
With these features, you can make your Gradle build file much more concise and easy to read:
...
android()
ios()
js()
sourceSets {
commonMain {
dependencies {
implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:$coroutinesVersion")
}
}
}
...
Don’t use kotlinx library artifact names with suffixes -common
or -native
, as they are no longer supported. Instead, use the library root artifact name, which in the example above is kotlinx-coroutines-core
.
尝试分层项目结构
With the new hierarchical project structure support, you can share code among several targets in a multiplatform project. You can use platform-dependent libraries, such as Foundation
, UIKit
, and posix
in source sets shared among several native targets. This can help you share more native code without being limited by platform-specific dependencies.
By enabling the hierarchical structure along with its ability to use platform-dependent libraries in shared source sets, you can eliminate the need to use certain workarounds to get IDE support for sharing source sets among several native targets, for example iosArm64
and iosX64
:
kotlin {
// workaround 1: select iOS target platform depending on the Xcode environment variables
val iOSTarget: (String, KotlinNativeTarget.() -> Unit) -> KotlinNativeTarget =
if (System.getenv("SDK_NAME")?.startsWith("iphoneos") == true)
::iosArm64
else
::iosX64
iOSTarget("ios")
}
# workaround 2: make symbolic links to use one source set for two targets
ln -s iosMain iosArm64Main && ln -s iosMain iosX64Main
Instead of doing this, you can create a hierarchical structure with target shortcuts available for typical multi-target scenarios, or you can manually declare and connect the source sets. For example, you can create two iOS targets and a shared source set with the ios()
shortcut:
kotlin {
ios() // iOS device and simulator targets; iosMain and iosTest source sets
}
To enable the hierarchical project structure along with the use of platform-dependent libraries in shared source sets, just add the following to your gradle.properties
:
kotlin.mpp.enableGranularSourceSetsMetadata=true
kotlin.native.enableDependencyPropagation=false
In future versions, the hierarchical project structure will become default for Kotlin multiplatform project, so we strongly encourage you to start using it now.
对于库作者
检查 Bintray 上传
The Bintray plugin doesn’t support publishing Gradle module metadata, but there are a couple of ways to get around this issue:
- Migrate to
maven-publish
instead ofgradle-bintray-plugin
as we did for kotlinx.serialization - Use a workaround for the Bintray plugin
While uploading your library to Bintray, you will see multiple versions for each artifact such as my-library-jvm
and my-library-js
.
To fix this, add systemProp.org.gradle.internal.publish.checksums.insecure=true
. See this issue for details.
This is a common Gradle 6.0 issue that is neither MPP nor Kotlin specific.
遵循默认库的布局
The layout of kotlinx libraries has changed and now corresponds to the default layout, which we recommend using:
The root or umbrella library module now has a name without a suffix (for example,kotlinx-coroutines-core
instead of kotlinx-coroutines-core-native
). Publishing libraries with maven-publish Gradle plugin follows this layout by default.
迁移到分层项目结构
A hierarchical project structure allows reusing code in similar targets, as well as publishing and consuming libraries with granular APIs targeting similar platforms. We recommend that you switch to the hierarchical project structure in your libraries when migrating to Kotlin 1.4.0:
- Libraries published with the hierarchical project structure are compatible with all kinds of projects, both with and without the hierarchical project structure. However, libraries published without the hierarchical project structure can’t be used in a shared native source set. So, for example, users with
ios()
shortcuts in theirgradle.build
files won’t be able to use your library in their iOS-shared code. - In future versions, the hierarchical project structure with the usage of platform-dependent libraries in shared source sets will be the default in multiplatform projects. So the sooner you support it, the sooner users will be able to migrate. We’ll also be very grateful if you report any bugs you find to our issue tracker.
To enable hierarchical project structure support, add the following to your gradle.properties
:
kotlin.mpp.enableGranularSourceSetsMetadata=true
对于构建作者
检查任务名称
The introduction of the hierarchical project structure in multiplatform projects resulted in a couple of changes to the names of some Gradle tasks:
- The
metadataJar
task has been renamed toallMetadataJar
- There are new
compile<SourceSet>KotlinMetadata
tasks for all published intermediate source-sets
These changes are relevant only for projects with the hierarchical project structure.
对于 Kotlin/JS 目标
与 npm 依赖关系管理相关的变更
When declaring dependencies on npm packages, you are now required to explicitly specify a version or version range based on npm’s semver syntax. Specifying multiple version ranges is also supported.
While we don’t recommend it, you can use a wildcard *
in place of a version number if you do not want to specify a version or version range explicitly.
与 Kotlin/JS IR 编译器相关的变更
Kotlin 1.4.0 introduces the Alpha IR compiler for Kotlin/JS. For more detailed information about the Kotlin/JS IR compiler’s backend and how to configure it, consult the documentation.
To choose between the different Kotlin/JS compiler options, set the key kotlin.js.compiler
in your gradle.properties
to legacy
, ir
, or both
. Alternatively, pass LEGACY
, IR
, or BOTH
to the js
function in your build.gradle(.kts)
.
kotlin {
js(IR) { // or: LEGACY, BOTH
// . . .
}
binaries.executable()
}
both
模式的变更
Choosing both
as the compiler option (so that it will compile with both the legacy and the IR backend) means that some Gradle tasks are renamed to explicitly mark them as only affecting the legacy compilation. compileKotlinJs
is renamed to compileKotlinJsLegacy
, and compileTestKotlinJs
is renamed to compileTestKotlinJsLegacy
.
显式切换可执行文件的创建
When using the IR compiler, the binaries.executable()
instruction must be present in the js
target configuration block of your build.gradle(.kts)
. If this option is omitted, only Kotlin-internal library files are generated. These files can be used from other projects, but not run on their own.
For backwards compatibility, when using the legacy compiler for Kotlin/JS, including or omitting binaries.executable()
will have no effect – executable files will be generated in either case. To make the legacy backend stop producing executable files without the presence of binaries.executable()
(for example, to improve build times where runnable artifacts aren't required), set kotlin.js.generate.executable.default=false
in your gradle.properties
.
与 Dukat 相关的变更
The Dukat integration for Gradle has received minor naming and functionality changes with Kotlin 1.4.0.
- The
kotlin.js.experimental.generateKotlinExternals
flag has been renamed tokotlin.js.generate.externals
. It controls the default behavior of Dukat for all specified npm dependencies. - The
npm
dependency function now takes a third parameter after the package name and version:generateExternals
. This allows you to individually control whether Dukat should generate declarations for a specific dependency, and it overrides thegenerateKotlinExternals
setting.
A way to manually trigger the generation of Kotlin externals is also available. Please consult the documentation for more information.
在 Kotlin 1.3.x 项目中使用 Kotlin 1.4.x 构建的构件
The choice between the IR
and LEGACY
compilers was not yet available in Kotlin 1.3.xx. Because of this, you may encounter a Gradle error Cannot choose between the following variants...
if one of your dependencies (or any transitive dependency) was built using Kotlin 1.4+ but your project uses Kotlin 1.3.xx. A workaround is provided here.

I was reading through one of Grizzled Dwarflord's builds and he explained that he wanted to take at least 28 levels in Ranger to get the most out of his pet. He suggested that there was some sort of diminishing returns on pets but he could't recall exactly what the cutoff was. He guessed at level 28.
So does anyone else know anything about this? It was the only place I've seen it mentioned.
Here's the link to his build... Brood II...Ranger28/Bard2/RDD10
I don't know anything about it, may be that after that level the Animal Companion stops improving or improves slower, but IIRC with my Druid Animal Companion (which is the same) it keeps improving up to level 40. Take in account that's a post from May 2005 and there could be some changes with the new versions, you might want to ask Grizzled_Dwarflord directly.

Maybe griz just had had too many ales? _________________ "With Europe liberated, the people of the world turned their attention to that old devil, the United States of America [...] We taught that monster of old the true meaning of freedom." Star Wreck
yea, grizz is implying that after 30 levels of ranger, the pet is not going to improve all that much. But before that, each of those ranger levels is needed to improve the poor little creature. i would highly recommend buffing your pet to get the most out of it. any item that grants the ability to perform minor buffs (aid, bless, endurance, ghostly visage, bull's strength, etc.) is a big help, since the only real buffs that a ranger can give to their pet are cat's grace, magic fangs/greater magic fangs, resist elemenets/protection from elements. Don't get me wrong, these are good buffs, but the more the merrier. if you have boots of the gargoyle, considering using them to buff your pet, for example. the buff goes a long way for your pet, especially in battles with hordes of minor threats. just my two cents.
-cs
OK thanks for the info guys. Seems like the pets just keep getting better the higher their level without any diminishing returns. Thanks for the clarification.

A lot of websites now provide a way to authenticate yourself via OpenID. That way, you don't have to remember a separate username and password to login to such a website, while still being secure.
The only challenge in using openid is remembering your openid URL, because there are quite a few possible openid providers. I currently can choose from (amongst others) Google, Yahoo, mijnopenid.nl, hyves.nl and quite a few others. Instead of remembering the username/password you have to remember which openid provider you've used for what account - which I think is the reason other authentication mechanism as facebook's connect are becoming more popular. I'll write about that later, in this page I just want to explain how I made my homepage, www.gerbrand-ict.nl an openid provider.

Flavoured with gooseberries and elderflower cordial, these summery little cakes are very similar to French friands.
Preheat the oven to 150C/300F/Gas 2. Brush a bun or muffin tin with melted butter.
Place the caster sugar with two tablespoons of water into a small saucepan and heat, stirring, until the sugar has dissolved. Add the gooseberries and simmer in the syrup for five minutes until soft, stirring occasionally, but be careful not to break them up too much.
In a large mixing bowl, combine the almonds and flour then sift in the icing sugar.
Stir in the egg whites until just combined, then stir in the melted butter and the elderflower cordial.
Transfer the batter in spoonfuls to the muffin tin. Place 3-4 stewed gooseberries into the centre of each cake.
Bake in the oven for 35-40 minutes, or until the cakes feel springy to touch and begin to pull away from the edges of the tin.
Remove from the oven and allow to cool in the tin for five minutes, then transfer carefully to a wire rack. These are best eaten warm with a dollop of cream.

With sombre mien, the Evening gray
Comes nagging at the heels of Day,
And driven faster and still faster
Before the dusky–mantled Master,
The light fades from her fearful eyes,
She hastens, stumbles, falls, and dies.
Beside me Amaryllis weeps;
The swelling tears obscure the deeps
Of her dark eyes, as, mistily,
The rushing rain conceals the sea.
Here, lay my tuneless reed away,—
I have no heart to tempt a lay.
I scent the perfume of the rose
Which by my crystal fountain grows.
In this sad time, are roses blowing?
And thou, my fountain, art thou flowing,
While I who watched thy waters spring
Am all too sad to smile or sing?
Nay, give me back my pipe again,
It yet shall breathe this single strain:
Farewell to Arcady!


--- title: Lesson 2 - Tabular Regression and Permutation Importance keywords: fastai sidebar: home_sidebar nb_path: "nbs/course2020/tabular/02_Regression_and_Permutation_Importance.ipynb" ---
Rossmann's Kaggle competition was a business sales prediction competition for $35,000 dollars to the winners.
The premise is that we're given the sales data and information of their stores for the past few years. We need to make a model that can predict the number of sales that will be made in the future.
We can do this through a tabular regression model.
Jeremy walks through feature engineering for this problem, for today though we will download a clean engineered dataset straight from Kaggle. To download it:
output
!wget {url}
(Note: to walk through the feature engineering, see this notebook)
train = 'ENTER_URL_HERE'
test = 'ENTER_URL_HERE'
!wget {train} -q
!wget {test} -q
And now that we have our data, let's install the fastai
library
from fastai.tabular.all import *
train_df = pd.read_pickle('train_clean')
test_df = pd.read_pickle('test_clean')
train_df.head().T
With our time-series based approach, the feature engineering made a bunch of date-related categorical columns that we can utilize in our embeddings.
cat_vars = ['Store', 'DayOfWeek', 'Year', 'Month', 'Day', 'StateHoliday', 'CompetitionMonthsOpen',
'Promo2Weeks', 'StoreType', 'Assortment', 'PromoInterval', 'CompetitionOpenSinceYear', 'Promo2SinceYear',
'State', 'Week', 'Events', 'Promo_fw', 'Promo_bw', 'StateHoliday_fw', 'StateHoliday_bw',
'SchoolHoliday_fw', 'SchoolHoliday_bw', 'Promo', 'SchoolHoliday']
cont_vars = ['CompetitionDistance', 'Max_TemperatureC', 'Mean_TemperatureC', 'Min_TemperatureC',
'Max_Humidity', 'Mean_Humidity', 'Min_Humidity', 'Max_Wind_SpeedKm_h',
'Mean_Wind_SpeedKm_h', 'CloudCover', 'trend', 'trend_DE',
'AfterStateHoliday', 'BeforeStateHoliday']
dep_var = 'Sales'
When doing Regression with these large numbers, we often use the log of these values for our y
's. Let's transform them real quick:
train_df[dep_var] = np.log(train_df[dep_var])
Now let's declare our procs
procs = [FillMissing, Normalize, Categorify]
And splits. Now we want to ensure that (since this is time series) our validation and test
len(train_df), len(test_df)
test_df['Date'].min(), test_df['Date'].max()
Let's find that particular index
idx = train_df['Date'][(train_df['Date'] == train_df['Date'][len(test_df)])].index.max()
idx
So now our splits
will be every index after the 41395'th item
splits = (L(range(idx, len(train_df))),L(range(idx)))
splits
Let's make our TabularPandas
! Since we have a large DataFrame
, we can enable inplace
to True
and reduce_memory
to True
to save on some storage space (Note: reduce_memory
is by default True
). To use inplace
, we need to set chained_assignment
to None
in pandas
pd.options.mode.chained_assignment=None
to = TabularPandas(train_df, procs, cat_vars, cont_vars, dep_var, y_block=RegressionBlock(),
splits=splits, inplace=True, reduce_memory=True)
And now let's build our dataloaders
!
dls = to.dataloaders(bs=512)
dls.show_batch()
As we're doing regression, we want to dictate what the maximum value to be (and minimum) so we will use a y_range
max_log_y = np.max(train_df['Sales'])*1.2
max_log_y
And now we can make a y_range
y_range = torch.tensor([0, max_log_y]); y_range
Next comes our Learner
. We'll walk through each step
tc = tabular_config(ps=[0.001, 0.01], embed_p=0.04, y_range=y_range)
learn = tabular_learner(dls, layers=[1000,500],
metrics=exp_rmspe,
config=tc,
loss_func=MSELossFlat())
So we have a lot going on right there. ps
is overall dropout (helps with overfitting), embed_p
is dropout on the embedding weights, exp_rmspe
is Root Mean Square Percentage Error
Let's look at our model:
learn.summary()
learn.lr_find()
learn.fit_one_cycle(5, 3e-3, wd=0.2)
For comparison, an exp_rmspe
of 0.108 was 10th place
learn.export('myModel')
del learn
learn = load_learner('myModel')
Now we generate our test_dl
from our test_df
dl = learn.dls.test_dl(test_df)
We need to tell the Learner
to return the predictions for the test set we added
raw_test_preds = learn.get_preds(dl=dl)
Let's take a peek
raw_test_preds
You'll notice [0]
contains our predictions, and [1]
contains any labels (if we had any). This is nice because if we accidently run learn.validate()
on a non-labeled test set, we get the following:
learn.validate(dl=dl)
Still runs, just there are no labels so it's None
Now back to our predictions! We need to undo our log
transform first:
np.exp(raw_test_preds[0])
test_preds = np.exp(raw_test_preds[0]).numpy().T[0]
(If you want to learn about what T
does, compare below):
raw_test_preds[0].numpy()
test_preds
Now we can submit to Kaggle!
test_df['Sales'] = test_preds
test_df[['Id', "Sales"]] = test_df[['Id', 'Sales']].astype('int')
And finally we make our submission. NOTE: remove the index when generating your submission always!
test_df[['Id', 'Sales']].to_csv('submission.csv', index=False)
Permutation importance is a technique in which we shuffle each column in a dataframe and analyze how changing a particular column affected our y
values. The more that it was affected, the more "important" we can (generally) call a variable in our neural network. Let's build a quick algorithm to do this:
class PermutationImportance():
"Calculate and plot the permutation importance"
def __init__(self, learn:Learner, df=None, bs=None):
"Initialize with a test dataframe, a learner, and a metric"
self.learn = learn
self.df = df
bs = bs if bs is not None else learn.dls.bs
if self.df is not None:
self.dl = learn.dls.test_dl(self.df, bs=bs)
else:
self.dl = learn.dls[1]
self.x_names = learn.dls.x_names.filter(lambda x: '_na' not in x)
self.na = learn.dls.x_names.filter(lambda x: '_na' in x)
self.y = dls.y_names
self.results = self.calc_feat_importance()
self.plot_importance(self.ord_dic_to_df(self.results))
def measure_col(self, name:str):
"Measures change after column shuffle"
col = [name]
if f'{name}_na' in self.na: col.append(name)
orig = self.dl.items[col].values
perm = np.random.permutation(len(orig))

df_copy = df.copy()
df_copy['feature'] = df_copy['feature'].str.slice(0,25)
df_copy = df_copy.sort_values(by='importance', ascending=asc)[:limit].sort_values(by='importance', ascending=not(asc))
ax = df_copy.plot.barh(x='feature', y='importance', sort_columns=True, **kwargs)
for p in ax.patches:
ax.annotate(f'{p.get_width():.4f}', ((p.get_width() * 1.005), p.get_y() * 1.005))
And now we can simply call PermutationImportance
to run it!
res = PermutationImportance(learn, train_df.iloc[:1000], bs=64)
res.importance
