Methods for command line flags.
The list of all arguments is processed and flags (arguments starting with a
dash) are separated from the others.
The flag objects can be created at the module level or in the SHARED
section of a class. The command line is processed during startup, after
which the flag values are available for use.
See the
@http://www.zimbu.org/documentation/startup-sequence@startup sequence@
for details.
For example, with these flags:
ARG.Usage usage = NEW("Usage: %0% [flags] filename ...")
ARG.Bool verbose = NEW("v", "verbose", FALSE, "verbose messages")
ARG.Int number = NEW("n", "number", -1, "some number")
ARG.String text = NEW("t", "text", "not set", "some text").enableRepeat()
These command lines could be used:
prog -v -n123 -t foo -t bar someFile
prog -n=999 someFile otherFile
To see all the flags and usage the --help flag is supported by default:
prog --help
Usage: prog [flags] filename ...
Command line flags:
--morehelp show more verbose help
-n {number}
--number {number} some number
-t {string} ...
--text {string} ... some text
-v --verbose ... verbose messages
Arguments after "--" are not
recognized as a flag, even when they start with a dash. The "--" itself is
not included. For example, using "--help" as a file name:
prog -- --help
The dash by itself is handled like a non-flag argument. It is sometimes
used for a file name to indicate stdin or stdout.

Robert Redford's A River Runs Through It is not a film I watch often. It is a masterpiece -- one of the better films of recent years. Until 1994, it was my second favorite film of all time. The acting and direction is top-notch -- never sappy, always touching. A friend of mine once reported that he avoided it because "I was afraid it would just be really politically correct, and tick me off." All I could do was tell him to go in unbiased, and enjoy. It is one of the few movies that has completely reduced me to tears. But certain memories should not often be rereleased -- in the last few shots, you have to cry. Upon my first viewing I left bawling. It is not flawless -- but it is so very good, that you can't help but be effected. The opening is dangerously nolstalgic and sentimental -- watching these shots of people who have been dead so long, gives you a feeling of perspective and history observation that you will find in very few other films. Martin Scorsese once described the movies as a dream state -- like taking dope, and immersing yourself in an alternative world. That is what A River Runs Through It does. It exploits the unique power of cinema to engross you and help to forget your real self. Both times I've seen it, its been hard (again to quote Scorsese) waking up. But the dream is lovely.

Other Solutions
FOSS
One of Open-Source Software’s core aims is to shed light on the inner-workings of the programs we use. Whilst very noble, and having many other benefits, it fails to properly protect against the set of risks we have outlined.
As a simple example, an open-source social network will store data in a database, which will then be read and utilized by the providers of the social network in any way they see fit, leaving end-users on square-one.
This raises the larger problem of verifiability, that being open-source isn’t a guarantee that:
- No other software is running in the system - for example, a data-analytics engine
- The software advertised to run on the system is actually running on it - for example, a private messenger that has a back-door through an injected ad-tech snippet.
While open-source has numerous benefits, and is a very positive signal of trust-making, on its own it cannot ensure proper governance.
DLT
Distributed Ledger Technology (DLT) promises to solve the issue of verifiability through the usage of smart contracts. A smart contract is software that runs verifiably, and is also often verifiably open-sourced - ensuring that what you see is what you get.
Smart contracts running on a DLT are, by nature, fully transparent in both operation and data governance. They also prevent the kind of centralized analytics and data collection that plagues traditional software apps and platforms.
Unfortunately, the technology hasn’t evolved enough to run with the efficiency we expect of traditional software, and may not ever get close-enough to it due to fundamental computational penalties it incurs to maintain the abovementioned properties.
It does not mean we will not see a shift towards DLT technology in the near future, but it most likely means that we will still rely on traditional software for many common uses, for many years to come.
This also means that we need something to protect end-user safety in the current systems we use, while more human-centered technology is being perfected.
B-CORP
A B-Corporation is a certification that businesses, including software providers, can apply to, and maintain, paying a yearly fee to the accreditor.
The aims of the B-Corporation accredetation are to increase and celebrate accountability, transparency, social-responsibility and ethical nature of for-profit businesses.
In principle, software maintained by a certified B-Corporation should greatly mitigate the risks to end-users we have outlined. However, the certification does not specifically address these risks, providing leeway for companies to engage in practices that result in these risks materializing.
Furthermore, a B-Corp accredetation is legally non-binding with regards to the actions a software provider may take, which offers no legal protection for the end-user, both during the accredetation, nor if it is revoked.
CHT
The Center for Humane Technology (CHT) was born out of a frustration with current technology trends, and aims to both explore the psychological risks in continuing down the path we’re on, as well as explore and promote a healthy path forward.
The Center for Humane Technology conducts and promotes research, education, policy and software initiatives. These address many of the risks we have identified (and others we have not,) however the CHT does not offer a solid framework to protect end-users, and only provides advice on how to voluntarily mitigate the risks.

The data for these visuals were gathered from the unedited dataset provided by using Visual Basic in Excel. The code used for each the data in the graphs was broken up individual files for organization and can be found here.
The bar graph on the left represents how many of each pass type were used over the quarter. Looking at this, the monthly pass was the most common pass, while the staff annual was the least used pass. There was a large range between these two types that comes out to a 80,922 pass difference. If you hover each bar, you can see the specific amount of each.
This line graph was drawn from the averages of the distance travelled each month. As shown, there is a sharp drop between August and September at the end of the traditional summer break and continues to drop throughout the winter months, and appears to be starting to pick up again around March.
In addition to the duration of rides decreasing in the winter, the number of times passes used also decreased moving into November and December, while it appears to start picking up again in March when the dataset ends. This is releavant in seeing when the number of times bikes are being used increases or decreases.
To focus just one type of pass, click the others in the legend to elimate them from the current viewing. Clicking again can bring them back. This will also change the legend accordingly to the visible variables' scale(s) and will zoom in.

US envoy decries Chinese 'intimidation' in South China Sea
BANGKOK, Nov 4 — A US envoy denounced Chinese "intimidation" in the South China Sea at a meeting of South-east Asian leaders today and invited them to a special summit in Washington on behalf of President Donald Trump.
China has made sweeping maritime claims in the resource-rich waters of the South China Sea, and angered neighbours by sending ships into the busy waterway, where several members of the Association of South-east Asian Nations (Asean) also have claims.
“Beijing has used intimidation to try to stop Asean nations from exploiting the off-shore resources, blocking access to US$2.5 trillion (RM10.4 trillion) of oil and gas reserves alone,” US envoy Robert O'Brien told the Asean-US summit in a speech.
:The region has no interest in a new imperial era where a big country can rule others on a theory that might makes right,” added O'Brien, the White House national security adviser.
He also read a message from Trump inviting the AseanN leaders to "join me in the United States for a special summit, meeting at a time of mutual convenience in the first quarter of 2020."
Trump has skipped the Asean-US summit for the past two years, sending Vice President Mike Pence in 2018.
At this year's summit, US Commerce Secretary Wilbur Ross was the highest-ranking delegation official, prompting the 10-member Asean to downgrade the summit to a "troika" attended only by top leaders from Thailand, Vietnam and Laos. — Reuters

pgs
pgs <address>
Examples:
-
"pgs"
- List the graphics string at DS:SI
-
"pgs ^hdi"
- Lift the graphics string whose handle is in DI, starting at the current position.
-
"pgs -s ^hdi"
- List the graphics string whose handle is in DI, starting at the beginning of the graphics string.
-
"pgs -l3 ^hdi"
-
List three elements of the graphics string whose handle is in DI, starting at the current position.
List the contents of a graphics string.
-
The <address> argument is the address of a graphics string. If none is specified then DS:SI is used as a pointer to a graphics string.
-
The passed address may also be the base of a gstate (e.g. "^hdi"). In this case, the gstring that is associated with the gstate will be printed.
-
The -s option can be used to specify that the gstring should be listed from the beginning of the string. By default, gstrings will be listed starting at the current position.
-
The -g option can be used to specify that the passed address is the address of a GrObj (GStringClass) object-- the gstring for that object will be listed.

phandle
phandle <handle ID>
Examples:
-
"phandle 1a8ch"
-
print the handle 1a8ch
Print out a handle.
-
The <handle ID> argument is just the handle number. Make sure that the proper radix is used.
-
The size is in paragraphs.
See Also: hwalk,
lhwalk.
pharray
pharray [<flags>] [<vmfile> <dirblk>]
Examples:
-

-
"pharray dx cx"
-
Print the huge array at ^vdx:cx (header only)
-
"pharray -e"
- Print the huge array at ^vbx:di and print the elements in the array
-
"pharray -tMyStruct"
-
Print the huge array at ^vbx:di and print the elements where the elements are of type MyStruct
-
"pharray -e3"
-
Print the huge array at ^vbx:di and print the third element
-
"pharray -h"
- Print the header of the HugeArray at ^vbx:di, using the default header type (HugeArrayDirectory).
-
"pharray -hMyHeader"

-
The flags argument can be any combination of the flags `e', `t', and `h'. The `e' flag prints all elements. If followed by a number "-e3", then only the third element is printed.
The `t' flag specifies the elements' type. It should be followed immediately by the element type. You can also use "gstring", in which case the elements will be interpreted as GString Elements.
The `h' flag specifies the header type. It should be followed immediately by the element type. If no options are specified, then "-hHugeArrayDirectory" is used. If any other options are specified, then the printing of the header is disabled. So, for example, if you want both the header and the third element, use "-h -e3".
The `d' flag specifies that the HugeArray directory entries should be printed out.
The `l' flag specified how many elements to print.
The `s' flag requests that a summary table be printed.
All flags are optional and may be combined.
-
The address arguments are the VM file handle and the VM block handle for the directory block. If nothing is specified, then bx:di is used
pini
pini [<category>]
Examples:
-
"pini Lights Out"
-
Print out the contents of the Lights Out category in each .ini file
-
"pini"
- Print out each currently loaded .ini file.
Provides you with the contents of the .ini files being used by the current GEOS session.
<category> may contain spaces and other such fun things. In fact, if you attempt to quote the argument (e.g. "pini {Lights Out}"), this will not find the category.

Margin, border and padding are the spaces between elements and can be manipulated with CSS. Here are the definitions.
Margin:The outermost section of the page, surrounding the border
Border:The space between the margin and the padding
Padding:The space between the border and the content
When combined these elements create the CSS Box Model.
This CSS code can be used to adjust the margin of the page, just specify the desired measurement in your code after the colon:
To adjust all the margins in one go use the below code to specify the measurement of each side desired (the specified measurements are applied to the element clockwise):
The border element can be customised in a few ways:
The style property can change the shape of the border and includes none, dotted, dashed, solid and double.
The width property sets the width for each side of the border.
You can set one value to be applied to all sides of the border like this:
Or you can customise each side by stating up to four values, applied clockwise.
This example would apply a thin width to the top and bottom borders and 2px width to the left and right borders.
The colour property changes the colour of the border and can also be customised for each side of the border by stating up to four values.
Similar to the margin code, the code for padding includes the ability to set each direction:
You can also join this altogether in one code (the specified sizes are applied to the element clockwise):

I am a technology addict, and I love trying new things. One thing that has always been important to me is how they all work together to form a greater whole. Above that, some weeks ago, together with my Squarespace move, I decided to not have personal servers anymore. Not sure how long this will hold, but I will try. Servers at home are excluded, and … a never mind, you get the point. E.g. I love Noserub, but I will run it hosted by somebody else.

But back to the main point. My Rememberall. There is so much stuff going on around you that you really need an infrastructure to keep yourself sane enough. It is probably easiest to understand how I use things by going through the day.

A) E-Mail: To start of I check my mail, yeah, I still do, and make sure only stuff I have to answer remains. Things I can answer now, are answered, things that I want to answer later remain, and things that are ToDo’s are forwarded to my private E-Mail address at Remember The Milk so they end up becoming (unsorted) ToDo’s. All else is archived directly through a Keyboard shortcut (thanks Mail Act-On). I say archived because all mails are in GMail and never deleted.

B) RSS: Yes, RSS is not dead for me yet. I use Google Reader and am very happy with it. I always read the "All Items" list, navigating through keyboard shortcuts. Especially on the iPhone, where I use Byline which syncs with Reader, I mark things as Favorite that I want to closer read later. If I already know that I like it but want to share it with the world, I "share" it potentially with note, which is automatically ending up in my Tumblr Blog at stuff.thylmann.net.

C) Twitter: Some here, I use favorites to mark things I want to read later. I am switching clients on the Desktop but on the iPhone I end up using Tweetie, even though I tried several others.

D) Read it Later: This wonderful service actually is used to add anything that I want to read later while in the browser. It includes an iPhone app that syncs via Nocat and hence I have lots of stuff to read later on my iPhone to read whenever I have the time. It also brings me to my next point. There also are two Bookmark lists for reading very shortly and reading some time, but let’s see where they end up at in a few weeks.

E) Remembering: I leave that with Evernote really. Whatever I have read and liked, whatever I think I would like to save, whatever I want to remember, it ends up in Evernote. Either through a forward in Read it Later, via a Bookmarklet or right from the Mac. And it ends up in Spotlight on the Mac too.

F) Friendfeed: I am actually not sure what to od with this now. I was actually setting it up as my personal search engine. I ended up adding people I think are emm… intelligent and as they add all their personal feeds to their accounts, I presume in the long term it will/would have allow(ed) me to get very good search results. Sadly now they have been bought by Facebook so I will have to revisit Noserub again but that is against my idea of not having a server. Maybe just locally. ;)

G) What is missing: I still need one thing that aggregates it all really. I’d like all that is being shared with notes to end up somewhere, full content, all items in evernote, all my twitter messages, all my blog posts, all my photos, whatever. It is still a little bit too distributed. But as distributed is the way of the future I am looking forward to using this setup now and re-integrating that. I am hoping for a few things for the new Social Timeline being developed by Squarespace.

So what are you using as your rememberall.

This is the thirteenth part of a series of posts looking at the PCI recommendations for container security as they apply to Kubernetes environments. This time we’re looking at the “Registry” section which talks about Container Registry controls. An index of the posts in this series can be found here.
Container registries are a key part of an Kubernetes environment as they store the images which are used to create the containers that run the applications hosted in the cluster. Also as I mentioned in the post on patching, software updates should be carried by re-building images, pushing them to the registry and then rolling out the new version of the application. This means that the registry is a key part of the update process.
From a technology standpoint container registries are relatively simple. They provide an HTTP API which follows the OCI distribution specification. The OCI distribution specification is a standard for how to interact with a registry, it doesn’t specify how the registry is implemented. There are a number of different implementations of the specification, including Docker Hub, Azure Container Registry, Google Container Registry and Amazon Elastic Container Registry. The specification is also implemented by Harbor, an open source registry implementation.
OCI Registries can also be used to store other types of artifacts, such as Helm charts, using projects like ORAS but for the purposes of this post I’m going to focus on the storage of container images.
An important point about registries is that public images in registries like Docker Hub are not necessarily maintained/curated. There is a set of Docker Official Images which are generally maintained (although some are deprecated so care is still needed) but there are also a lot of images which are not maintained by anyone. This means that you should be careful about using images from public registries, especially if they are not maintained by a trusted source. You should also be careful about using images from private registries that you don’t control. If you’re using a private registry you should be careful about who has access to it and what images are stored in it.
In terms of managing images for production systems, the safest approach is to combine internally managed images hosted in a private registry with public images where required. The public images should be signed using something like cosign or pinned to specific SHA256 hashes. This means that you can be sure that the image you’re using is the one you expect and that it hasn’t been modified.
In terms of the PCI requirements there’s four in this section.
Section 13.1
Threat - Unauthorized modification of an organization’s container images could allow an attacker to place malicious software into the production container environment.
Best Practice - a. Access to container registries managed by the organization should be controlled. b. Rights to modify or replace images should be limited to authorized individuals.
Details - Exact details of how this is achieved will depend on the registry or registries in use, but access control should be applied to any modification of the images in the registry. Reviewing for this could be done by listing the container images in use in a cluster and then testing to see whether these images are accessible publicly/without authentication and confirming that attempts to modify them without authentication are rejected.
Section 13.2
Threat - A lack of segregation between production and non-production container registries may result in insecure images deployed to the production environment.
Best Practice - Consider using two registries, one for production or business-critical workloads and one for development/test purposes, to assist in preventing image sprawl and the opportunity for an unmaintained or vulnerable image being accidentally pulled into a production cluster.
Details - Reviewing this recommendation would likely largely be done by speaking to the people responsible for the PCI environment and confirming which registries are used. A check coule be carried out again by listing the images in use in the cluster and then checking to see whether they are from a production or non-production registry.
Section 13.3
Threat - Vulnerabilities can be present in base images, regardless of the source of the images, via misconfiguration and other methods.
Best Practice - If available, registries should regularly scan images and prevent vulnerable images from being deployed to container runtime environments.
Details - Vulnerability scanning at the registry level is one of the better approaches to container vulnerability scanning as the registry should be the canonical source of images. Some registries will provide image scanning functionality directly, or third-party scanning tools such as Trivy can be used to scan images.
Section 13.4
Threat - Known good images can be maliciously or inadvertently substituted or modified and deployed to container runtime environments..
Best Practice - Registries should be configured to integrate with the image build processes such that only signed images from authorized build pipelines are available for deployment to container runtime environments.
Details - Image signing is a good control to help ensure that the images in the registry are the ones that you expect. The main ecosystem currently in use for this is sigstore which allows for signatures to be stored on a transparency log. This allows for the signatures to be verified without having to trust the registry.
Conclusion
Container registries are a vital part of any Kubernetes clusters, so it’s not surprising that there are control recommendations relating to them. Used correctly, they can help ensure that Kubernetes clusters are running trusted and up to date images.

Ohio's religious liberty measure kicks up controversy over application to students
by Bradford BetzCritics of a religious liberty bill passed by Ohio state lawmakers on Wednesday say the measure will allow students to avoid penalties for scientifically wrong answers if those answers happen to conform with their religious beliefs.
The Ohio House passed HB 164, or the “Student Religious Liberties Act,” in a 61-31 vote Wednesday, cleveland.com.
Among the bill’s provisions is the mandate that teachers “shall not penalize or reward a student based on the religious content of a student’s work.”
Gary Daniels, the chief lobbyist of ACLU of Ohio, acknowledged that the bill would remove some restrictions on students’ religious rights, but talked about the student who turns in biology homework saying that the Earth is just 10,000 years old. Would he or she be penalized?
“Under HB 164, the answer is ‘no,’ as this legislation clearly states the instructor ‘shall not penalize or reward a student based on the religious content of a student’s work,” Daniels said.
GOP Rep. Timothy Ginter, who sponsored the bill, said it’s not that simple. “We live in a day when our young people are experiencing stress and danger and challenges we never experienced growing up,” he said.
FEDERAL COURT REVERSE DECISION BARRING CHRISTIAN SCHOOLS FROM PRAYING OVER LOUDSPEAKER BEFORE GAMES
Ginter said widening religious self-expression would be positive for students. In response to the critique that “anti-science” would go unpunished, Ginter said that students must turn in work that accurately reflects what is taught during the course, cleveland.com reported.

“This doesn’t give students a get-out-of-jail free card,” he said.

Shaun Edwards unveiled as France’s new defence coach
The former Wales coach will be part of Fabien Galthie’s backroom team.
Shaun Edwards has made his first appearance in the blue of France after being unveiled as les Bleus’ new defence coach.
Edwards spent almost 12 years in a similar role with Wales, building a formidable reputation, and departed alongside head coach Warren Gatland following the side’s fourth-place finish at the World Cup.
France are also at the start of a new era having been beaten 20-19 by the Welsh in the quarter-finals of the tournament, with Fabien Galthie taking over from Jacques Brunel in charge of the team.
Speaking after being presented with the rest of a new-look coaching group, which also includes Laurent Labit, William Servat, Karim Ghezal, Thibault Giroud and Nicolas Buffa, Edwards said: “I’m happy to join France’s adventure alongside Fabien and Raphael.
“My goal is to maximise the speed of the defensive play in the French team. This method has already been successful in the past.”
Edwards, 53, helped Wales to to four Six Nations titles, three Grand Slams and two World Cup semi-finals during his spell with Gatland.
Edwards' achievements with Wales
• 4 Six Nations titles
• 3 Grand Slams
• 2 World Cup semi-finals
His next move was originally expected to be a cross-code switch back to rugby league as head coach of Wigan, a deal he once appeared set to embrace but eventually backed away from, citing a lack of preparation time.
It had seemed he was being lined up to remain with the Welsh Rugby Union but, while he will still be involved in the familiar environment of the Six Nations next year, it will be as part of a different dressing room.
France kick off their campaign against World Cup runners-up England on February 2, with Edwards’ Welsh reunion scheduled for Cardiff’s Principality Stadium on Feb 22.


Strata+Hadoop World and Beam
Tyler Akidau and I gave a three-hour tutorial on Apache Beam at Strata+Hadoop World 2016. We had a plethora of help from our TAs: Kenn Knowles, Reuven Lax, Felipe Hoffa, Slava Chernyak, and Jamie Grier. There were a total of 66 people that attended the session.
If you want to take a look at the tutorial materials, we’ve put them up on GitHub. This includes the actual slides as well as the exercises that we covered. If you’re looking to learn a little about Beam, this is a good way to start. The exercises are based on an imaginary mobile game where data needs processing and are based on code in the Beam examples directory. The code has TODOs for where you need to fill in code or there are full sample solutions to look over our code. You can run these examples on your own machine or on a cluster using a runner that Beam supports.
I want to share some of takeaways I had about Beam during the conference.
The Data Engineers are looking to Beam as a way to future-proof, meaning that code is portable between the various Big Data frameworks. In fact, many of the attendees were still on Hadoop MapReduce and looking to transition to a new framework. They’re realizing that continually rewriting code isn’t the most productive approach.
Data Scientists are really interested in using Beam. They interested in having a single API for doing analysis instead of several different APIs. We talked about Beam’s progress on the Python API. If you want to take a peek, it’s being actively developed on a feature branch. As Beam matures, we’re looking to add other supported languages.
We heard loud and clear from Beam users that great runner support is crucial to adoption. We have great Apache Flink support. During the conference we had some more volunteers offer their help on the Spark runner.
On management and thought leader side, Beam went from “what’s Beam?” at previous conferences to “I’m interested in Beam.” or “I’ve formed an informed opinion on Beam.” at this conference. This is one of the metrics I look for in early technology adoption.
We rounded out the tutorial with live demonstrations of Beam running on Apache Spark, Apache Flink, the local runner, and DataFlow runner. Then, we brought in the big brainpower and had a Q and A session.
If you’re attending a conference, we encourage you to look for a Beam session. If you want to use these materials to give your own Beam talk or tutorial, we’re happy to help you. In addition to this tutorial, we have other presentation materials. You can reach out to us on the user mailing list.

Running any NPM pacakge in the browser locally
JavaScript has never had any official solution for distributing packages, and every web platform (Rails, Django etc) has their own idea of how to structure and package JavaScript. In the last few years NPM has started becoming the canonical way of distribution, with Webpack as the build system, but there’s no way to load NPM packages in the browser without a server-side component.
Scrimba is a platform for interactive coding screencast where you can run the code at any moment in time. Being able to use NPM packages has been a frequently requested feature, but it turns out to be surprisingly technically difficult to implement. In this article I will explain how we tackled the problem and the final solution we ended up with.
Our solution (inspired by StackBlitz) runs almost entirely on the
client-side. Dependency resolution is done server-side, but fetching NPM
files, parsing require()
, resolving require paths and
creating a bundle is all done at the client. This (combined with
IndexedDB caching) gives a smooth experience with very low latency.
What is involved in supporting NPM?
There are two very distinct steps in supporting NPM: Dependency resolution and module loading.
Dependency resolution is about going from a dependency requirement,
to a concrete description of what packages needs to be installed:
node_modules/react<EMAIL_ADDRESS>node_modules/react-dom<EMAIL_ADDRESS>node_modules/fbjs<EMAIL_ADDRESS>...
Module loading is more involved and includes:
-
Figuring out that
require("react")
in app.js refers to node_modules/react/index.js - Making sure dependencies are available before the module body is being executed
-
Providing
exports
,module
,process
variables inside the module body
Dependency resolution
Yarn is a package manager for NPM
which you can use a library. There is not a public API
available at the moment, but as long as you depend on a fixed version
everything works out nicely. Yarn has a
PackageResolver
which resolves all dependencies, and with
the PackageHoister
you can find the paths where packages
needs to be installed. Yarn is decently decoupled and although it lacks
documentation about the internal classes it’s quite easy to figure
things out.
Yarn 1.3 was recently released and includes a bunch of new features!
Module loader: Webpack
There are some online coding sandboxes (Webpackbin and CodeSandbox) which supports NPM packages through server-side Webpack. Their approach is essentially as follows:
First they have a packager which takes a list of fully resolved
packages (e.g react<EMAIL_ADDRESS>), generates a
package.json
, install packages and dependencies with
yarn
, and then uses Webpack to build a
DLL package. A
DLL package is a way of bundling all files into a single Webpack bundle.
Packaging can take a while (>10s), but it’s only needed once per
request and you can cache the produced package indefinitely.
When you want to execute your app.js you send it to the server, generate a Webpack configuration (which includes a reference to the DLL package) and Webpack will resolve everything for you.
There are two big disadvantages with this approach:
- Building the initial package can take a long time. This needs to be done on the server-side and its scalability is limited by how many servers you have.
- Packages can only be cached as a whole. This means that if you add one small dependency you must still create a whole new package.
We created a prototype together with Christian Alfoni (the creator of Webpackbin), but had some pending work when we discovered a different approach.
Yarn 1.3 was recently released and includes a bunch of new features!
Hello
Module loader: Unpkg + SystemJS
StackBlitz is an online coding sandbox which supports NPM without using Webpack at all. They briefly described their approach in a comment at the unpkg-repo:
In short, SystemJS & Unpkg are an incredible duo for dev UX because they reflect what makes local dev environments great: the client is doing all of the downloading, installing, bundling, and even serving the application.
They haven’t open-sourced their solution yet, but from their description we can still go through how it works. Let’s say we have an app.js which contains the following:
This can be defined as a module in SystemJS and it will start doing its
magic. The required paths (react
and
react-dom
) will be extracted and attempted resolved. By
writing a SystemJS-plugin we can integrate with
Unpkg and fetch files directly from NPM
packages:
-
First we can load
<EMAIL_ADDRESS>to find the main file. In this case it’s
index.js
. - Then we can fetch<EMAIL_ADDRESS>directly and register it as a SystemJS module.
- SystemJS will extract the required paths from this file and recursively fetch/register all dependent files.
- Once everything is complete we can execute our original app.js.
From StackBlitz’ description we implemented a prototype in Scrimba, and we had the following experiences:
- It turns out that SystemJS’s built-in resolve logic doesn’t completely match Node’s, and there’s quite a few packages which depends on Node’s behaviour. We ended up writing our custom path resolver.
- SystemJS is slow. Even though we cached the content of the files and did no HTTP requests at all, it took around 150ms to just resolve all dependencies. It seems to be caused by heavily use of Promises which causes overhead when there’s no asynchronicity.
In the end we felt we needed to re-invent many parts of SystemJS in order to get the correct behaviour, and the parts left of SystemJS were slow or not in use.
Module loader: Custom loader (our approach)
Our final solution uses a module loader we wrote for our use case. It consists of several decoupled parts which combines into a complete solution. The project is called “mrmanager” and is currently not open-sourced, but if there’s interest we can make it happen.
First there’s a virtual file system. The file system handles require path resolution and integrates with Unpkg to fetch NPM files.
1var fs = new FileSystem; 2 3// Set up file system: 4var npm = new PackageSet; 5fs.mount("/node_modules/react/", npm.get("react@16.0.0"); 6fs.mount("/node_modules/react-dom/", npm.get("react-dom@16.0.0"); 7 8var static = new StaticMount({"app.js": "require('react')"}); 9fs.mount("/", static); 10 11// Resolve paths relative to a directory: 12var path = await fs.resolve("react", "/") 13 14// result: /node_modules/react/index.js 15 16// Fetch the body 17var body = await fs.fetch(path);
Then we have the module system. This provides a way to register modules and execute modules:
1var system = new ModuleSystem; 2 3// Define module 4system.define("/app.js", function(require, module, exports) { 5 var React = require("react"); 6}); 7 8// Register mappings 9system.registerResolve("react", "/", "/node_modules/react/index.js"); 10 11// Execute module 12var result = system.moduleResult("/app.js")
Note that the module system does not parse require paths or fetch dependencies, and you must handle this at a different level. It’s your responsibilty to define all modules before you attempt to execute them. This is a way of simplifying the module system to its most basic features and allowing for different approaches to dependency handling.
The final piece of the puzzle is the loader. The loader combines the module system with the file system such that:
- The loader will use the file system to fetch the code
- It will parse the code for dependencies, fetch the dependencies, resolve all paths and make sure everything is available. This is done recursively.
-
The code will be wrapped inside a
system.define(name, function() { … }
-block - The wrapped code for all files is concatenated together to one big string
- Once all dependencies are loaded, it will execute the code once. This will register every file to the module system, and we’re now ready to invoke the main file.
The crucial part here (compared to SystemJS) is that we combine all the processed files into one big string and (1) execute it at once and (2) cache it all together. In SystemJS the only unit you can cache is a file and SystemJS will every time re-parse require paths, resolve those paths and so on.
This is a good example of how decoupling two system (the module system and the dependency system) gives us greater flexibility even though we’re always going to use them together. By decoupling them we have clearly defined what the module system needs to function. After careful consideration we found a way to cache this in the most performant way.
The end result? From a hot cache, mrmanager is capable of executing React (with ReactDOM) in 9ms instead of SystemJS’ 150ms. Those milliseconds matter when you want to quickly iterate on small projects.
I must again clarify that it was not only performance which lead us to a custom approach. In our SystemJS-prototype we ended up using just a fraction of SystemJS, reinventing parts of it, and monkey-patching various functions. That’s not a criticism of SystemJS itself, but a sign that it hasn’t been designed for our use case.

In general, there are two approaches to running tests built against earlier versions of the NUnit framework from 2.0 through 2.5.10:
Note: NUnit 2.6 no longer recognizes "old style" test cases - those identified by a name beginning with "Test". If you have such tests, you will need to convert them to use the and recompile your tests. In such cases, it makes sense to recompile against the latest framework.
Tests originally compiled against a version of NUnit prior to 2.0 will need to be rewritten and recompiled in order to run under NUnit 2.6.

Qt-4.8.6 (for the testsuite)
User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/qtchooser
If both Qt4 and Qt5 are installed on the system, then Qt4 should be set as default unless stated otherwise.
Install qtchooser by running the following commands:
patch -Np1 -i ../qtchooser-39-upstream_fixes-1.patch && make
To test the results, issue: make check.
Now, as the root
user:
make install
The /etc/xdg/qtchooser/default.conf
configuration file contains paths to the Qt binaries and libraries which will be used
when the wrapper is run. It is ussually a symlink to a package
specific file, such as 4.conf
or
5.conf
. In first case, when
invoking the wrappers, Qt4
equivalents will be invoked. In second case, Qt5 equivalents will be invoked.
If both Qt4 and Qt5 are installed in /usr
, create the configuration files by running
the following commands as the root
user:
install -v -dm755 /etc/xdg/qtchooser && cat > /etc/xdg/qtchooser/qt4.conf << "EOF"/usr/lib/qt4/bin /usr/lib
EOF cat > /etc/xdg/qtchooser/qt5.conf << "EOF"/usr/lib/qt5/bin /usr/lib
EOF
If both Qt4 and Qt5 are installed in /opt
, create the configuration files by running
the following commands as the root
user:
install -v -dm755 /etc/xdg/qtchooser && cat > /etc/xdg/qtchooser/qt4.conf << "EOF"/opt/qt4/lib/qt4/bin /opt/qt4/lib
EOF cat > /etc/xdg/qtchooser/qt5.conf << "EOF"/opt/qt5/lib/qt5/bin /opt/qt5/lib
EOF
Replace /opt/qt4
and/or
/opt/qt5
if you used different
prefix.
To set Qt4 as the default, run
the following command as the root
user:
ln -sfv qt4.conf /etc/xdg/qtchooser/default.conf
To set Qt5 as the default, run
the following command as the root
user:
ln -sfv qt5.conf /etc/xdg/qtchooser/default.conf
You can also select default Qt using an environment variable.

All the animals that died in the attack belonged to a herder called Ismaila Mohammed.
As many as 40 cows belonging to different herders in the village were said to be tethered to posts in the open space where the animals usually stayed, when the thunderstrike was heard in the settlement around 6:30pm on Friday.
However, only those owned by Mohammad died in the incident.
In a chat with our Correspondent on Sunday, Special Adviser to Osun State Governor on Agriculture and Food Security, Abiodun Ajisefinni, who led a delegation that also included the Commissioner for Regional Integration and Special Duties, Lekan Badmus, to the scene of the incident, said the animals had been “evacuated and destroyed” to prevent epidemic.
Meanwhile, the leadership of the Fulani Community in the state has pleaded with Osun State Government to come to the aid of the herder that lost animals to the lightning.
Speaking with our Correspondent in Osogbo on Sunday, Seriki Fulani for the state, Oluwatoyin Suleiman, said the affected herder had lost all he laboured for over the years.
He also dismissed claims that Fulani herders were leaving the state as a result of the incident.
Suleiman said, “Fulani men are not leaving the state as a result of Friday’s incident.
“The movement of cows, cattle and other animals is a norm and practised by herders to find veritable locations to feed their animals.
“Although we are saddened by Friday’s incident, the state government has ensured that the affected animals were properly incinerated to avoid health and environmental hazard, while it should also look into the loss of the affected herder.”

on what the Buddha taught
In AN5.3.8 we find the following comparison:
‘He overﬂows, completely ﬂows, completely ﬁlls up, completely spreads this very body with delight and happiness by means of seclusion. There isn’t anything, from all of the body, not spread with delight and happiness by means of seclusion. Just as, almsmen, or a skilled barber or a barber’s apprentice would knead, in a bronze dish, bathing powders with water, sprinkling around and around finishing a ball from oil, affected with oil, from the inside and outside spread with oil and does not drip.‘
I have always been intrigued by the last part of not dripping. Why would this matter? If you spread out joy and pleasantness through and through, all over, why would dripping be a concern? Suppose you would paint a whole room, from top to bottom, ceiling, walls, floor everything; why would dripping (not making such a mess that it piles up, just dripping) on the floor matter? And... how would you even drip joy?!
Today I washed my hands in a very tiny washing basin; the soap is on a shelf on another wall. So I wet my hands (closed the crane), picked up de soap, turned it in my hands a few times and was about to put it back when I noticed the soap water dripping. I turned the soap a few times more, which made this soap water a bit thicker, so it wouldn't drip when put back. Then I thought about this sermon. The not dripping is not about not splashing it everywhere all around, it means it is to thin to work with; it can't be put in good use because it falls away. And it needs more of the same work first, to make it thicker, to be able to put it into good use.
Because of the oily ball part in that sermon, the instruction itself was not lost (to thin and the ball itself would fall apart). ‘Establish it‘ or ‘Establish it, else it is not workable‘ do not differ in ‘what to do‘. And there are more sermons stating the same (for example AN9.4.4 where a wise cow establishes her forefeet well before raising her hind feet in an unknown rocky area). Thus though it was not an issue, it is fun seeing this clarified.

***This experience report contains graphic descriptions of gay men having sex. Reader discretion is advised.***
I've been smoking weed for several years, and I've been using poppers during sex/masturbation for almost as long, but I never thought to mix them until a few weeks ago. Usually I either smoke a bowl or two of weed before sex, or whip out the popper bottle. No, I'm not dependent on either one to be able to have good sex, but it certainly makes it a lot more fun. The best orgasm I've ever had in my life happened the night I mixed poppers with weed for the first time.
It was around midnight and I was hanging out with my friend Peter. Peter and I usually end up fooling around when I go to his place, because we're both really horny people, and with two men, there's really no one there to say 'no.' Well, on the night in question, I had brought my brand new bottle of 'Blue Boy' poppers, purchased at my local den of sin (bathhouse), as well as my stash of weed.
Peter and I smoked some of weed, and watched a movie. I always have a great time watching movies when I'm stoned, so I enjoyed the movie quite a bit, though I can't remember what one it was. After the movie was done, so around 2 a.m., Peter and I smoked some more weed because we knew we were going to end up fooling around. We sat around chatting and enjoying his apartment (he's a fabulous interior designer, and we WERE stoned after all). After a while, he put on a porn movie and we started jerking off. Then I remembered my bottle of poppers and retrieved them from my backpack.
We cracked open the bottle of poppers and Peter took the first hit and continued jerking off. He then passed the bottle to me and I took my first hit. I inhaled deeply 4 times, 2 in each nostril.  So I impaled myself on it and shoved all 8' of it down my throat. By then my popper high was starting to wear off, so I sniffed some more. I'm not going to tell you every time I took a hit of poppers, because this story would be even longer than it's already going to be.
During the entire experience, I felt really warm and flushed, and my entire body felt good. It felt like I was an amusement park and I wanted Peter to try every ride. After I had had enough of being on my knees for him, we rearranged ourselves into a 69 position.
 After suiting him up in his latex armor, I took another big hit of poppers, and sat down on him. The entire room started to spin (in a good way) as he massaged my prostate. I rode him for a good hour, snorting poppers and feeling warm and rushy and horny the whole time. The room was spinning and I was spinning with it. The entire universe consisted of just the two of us getting our groove on, while lying on his fancy expensive Egyptian cotton sheets, which just made the whole experience that much better.
This was the night I discovered that sex feels really good when you mix weed and poppers, but it also lasts forever, because like magic mushrooms, it's very difficult to actually have an orgasm when mixing weed and poppers. Eventually, however, I could tell I was getting close, so I did another HUGE hit of poppers and just let it happen. My entire body exploded in a wave of pleasure more intense than anything I had ever experienced. I just rode the wave. I had my eyes closed the whole time and I was seeing colours and shapes, even with my eyes closed. Wave after wave of intense, screaming pleasure washed over me.
When I eventually opened my eyes, Peter was looking at me with an amused expression on his face. He then told me that for 2 solid minutes, I just sat there moaning and screaming, like I was having the orgasm of a lifetime, and I was. After he had his own screaming orgasm, we cleaned ourselves up. It took 4 towels instead of the usual one, because we were both coated in sweat and other bodily secretions.  The dreams were almost as good as the real thing.
Since then, I've mixed weed and poppers many more times, with the same amazing effects, and I plan on doing it many more times. Sorry if this story was too graphic, but I felt that in order to fully describe my experience, it had to be.

This Week’s iPhone Pics (33/52)
Moar like last month’s iPhone pics amirite? Anyways, this week’s combo is Jimmy on Blanko.
- Last bit of Montreal before takeoff: smoked meat in a bagel. It's doesn't get more local than this. Best airport food I've had so far.
- Something more exotic: Jamaican beer.
- In Florida, cars are clean. This particular picture shows a set of pristine BMW Z3 M Roadster wheels, dubbed Roadstars. 17x9, et8 in the rear... how's that for width and low offset? Near impossible to fit on any vehicle without serious bodywork, camber and tire stretch. Check the lip out on these bad boys. It's the kind of stuff I dream about these days...
- That's actually a real name for a real shop. Wow.
More pictures of my trip to Miami / the Caribbean via the Carnival Glory are coming up soon… the amount of 30+ shot panos and HDR shots I have to process is kind of slowing down my post-processing routine.

There are many methods used to calculate growing degree-days (GDD ). PhenologyMMS provides four methods, although default parameters for each crop are available for only one specific method. For example, parameters for Method 1 are provided for winter wheat while parameters for Method 2 for are provided for corn. A description of each of the Methods follows.
GDD Method 1 - this is a very common and simple method of calculating GDD. GDD is calculated by summing the daily maximum temperature (Tmax ) and the daily minimum temperature (Tmin ), dividing that result by two to estimate the daily average temperature (Tavg ), and then subtracting the base temperature (Tbase ) from Tavg. Tbase is the temperature below which the process of interest does not progress.
Tavg = ((Tmax + Tmin)/2)
GDD = (Tavg - Tbase)
Note: GDD >= 0 (i.e., cannot be negative). If the GDD value is less than zero, it is set equal to 0.0.
Method 1 is commonly used for small grains such as wheat, barley and millet.
GDD Method 2 - this method is a slight variation of GDD Method 1. The differences are: a) adding an upper temperature threshold (Tupper ), which limits the amount of GDD that can be accumulated for the day, and b) adjusting Tmax and Tmin for each day based on the base (Tbase) and upper (Tupper) thresholds as follows. Both Tmax and Tmin are compared to Tbase and if Tmax and/or Tmin is less than Tbase then Tmax and/or Tmin is set equal to Tbase. Likewise, if Tmax and/or Tmin is greater than Tupper, then Tmax and/or Tmin is set equal to Tupper. The average temperature is calculated and Tbase is subtracted from Tavg. If the resulting value is less than zero, then it is set to zero.
Method Two is used for Corn, Dry Beans, Sorghum, Soybean, and Sunflower.
GDD Method 3 - this method employs a two-segmented linear model. The first segment extends from Tbase to an Optimum Temperature (Topt ), and the second segment extends from Topt to Tupper. The Average temperature is calculated and compared to Tbase and Topt. If Tavg is greater than or equal to Tbase and less than or equal to Topt, then a temperature factor (tf ), which uses the slope of the first segment of the line, is calculated and multiplied by the value of Tavg minus Tbase. This gives the GDD value for the day. However, if the Tavg is greater than Topt and less than or equal to Tupper, then 'tf', which uses the slope of the second segment of the line, is multiplied by the value of Tavg minus Tbase to give today's GDD value. If neither comparisons are true and Tavg is less than Tbase or greater than Tupper, then the GDD for the day is zero.
GDD Method 4 - this method uses a three-segmented linear model. The first segment extends from Tbase to the Lower Optimum Temperature (Toptlo ); the second segment from Toptlo to the Upper Optimum Temperature (Toptup ); the third segment runs from Toptup to Tupper. The Average temperature (Tavg) is calculated and compared to Tbase and the Lower Optimum Temperature (Toptlo). If Tavg is greater than or equal to Tbase and if Tavg is less than Toptlo, then Tbase is subtracted from Tavg. This value is multiplied by the calculated temperature factor, 'tf' which is calculated using the slope of this first segment of the line to get the GDD value for the day. However, if Tavg is greater than or equal to Toptlo and less than or equal to Toptup, then Tbase is subtracted from Tavg and that value is multiplied by 'tf' which has been calculated using the slope of the second line segment (which is 1). This gives the GDD value for the day. If Tavg is greater than Toptup and less than or equal to Tupper, then 'tf' is calculated using the slope of the third segment of the line and is multiplied by the result of Tavg minus Tbase to yield the GDD value for the day. If none of the situations are true and Tavg is less than Tbase or greater than Tupper, then GDD for the day is set equal to zero.
All methods calculate thermal time as described above, however Methods 3 and 4 add another modifier to the thermal time calculation which assumes that not all temperatures between Tbase and the maximum temperature have the same effect on plant development. For example, temperatures at the optimum level (Method 3), or in the optimum range (Method 4) result in faster development than those near Tbase or the maximum temperature. Therefore, the calculated thermal time is then reduced by the 0-1 development rate factor (shown on the y-axis) to calculate the final thermal time for the day. Adding this development rate factor is often considered theoretically more correct, but often in practice for field conditions does not result in significant improvement in accuracy for many reasons. Further, it adds additional parameters for optimum temperature (or range) and uses a simple linear relationship. The figures for Methods 3 and 4 also show a curvilinear relationship for calculating thermal time and the development rate factor, but this approach has not been incorporated into PhenologyMMS.

Energy Monitoring using Smart plug and Raspberry Pi
Table of Contents
Recently, I became interested in measuring the electricity consumption of electronic devices at my home and, in particular, my computer. Computer power supplies are typically rated from 400W to 800W. I wanted to see how much power is actually needed for day-to-day computing - writing code, browsing the Internet, playing games, running ML jobs. And how does it compare with a laptop and other mobile devices.
As a kid, I was once told by an engineer that the bulk of the energy is consumed by the monitor, and the desktop itself consumes lesser energy1. So if I switch off the monitor, I can play music, download things overnight without wasting too much energy. This statement stuck with me over time as my bulky CRT monitor was replaced with sleek LED monitors and a beefy 250W GPU got added to my desktop. It was time I measure everything and find out if the engineer's statement still holds.

Hardware
A quick search revealed that Kill A Watt meters are one of the most popular ways of measuring the energy consumption. I wanted to log the consumption so that I can analyze the trends over time. That's why I passed these meters on. But these meters have an inbuilt screen and do not require mobile or network access so they can be a great solution if someone is looking for a quick way to see the consumption. On the other end of the spectrum, there are some devices that can be plugged directly into the circuit panel of the house and they can be used to analyze consumption of all appliances in the house. For my goal of measuring energy consumption of my computer, this was simply overkill and would not have provided the fine-grained monitoring I needed (and I'm a little scared of messing with the AC power).
I finally settled on TP-Link Power Strip: HS300. This smart power strip has the usual smart plug features, like, it can be controlled using a mobile app, but it also has energy monitoring built-in. And most importantly there are some awesome projects on Github - python-kasa, pyHS100 - that have reverse engineered the communication protocol and provide a nice interface to talk to them.
Software
Figure 2: Architecture
Figure 22 shows a high-level picture of how the energy consumption values get extracted, stored and visualized.
Polling HS300
The project python-kasa provides a nice interface to control TP-Link devices but there's an issue with querying the energy monitor of child plugs. That's why I used the project pyHS100 which seems like an older version of the python-kasa project. I added a cron job to query the power strip every 5 minutes and dump the data in a text file, using a simple bash script:
#! /bin/bash
power=$(/home/pi/.local/bin/pyhs100 --strip --host <IP of the power strip> emeter | tail -n 1)
timestamp=$(date +%s)
echo -e "$timestamp, $power"
This creates a bulky line for each sample it records and there is certainly a lot of room to compress it. I'm currently sampling it every 5 minutes, so I don't mind it, but if you are planning to sample it every minute or every few seconds, you might want to trim it down.
Grafana Datasource
I'm using Grafana to visualize this data to see trends in usage over time. We can dump all of the data into one of the Datasource that is supported by default by Grafana but I did not like that extra step for such simple data. So I wrote my own backend datasource that directly serves Grafana, data from the logs we collected. This uses the SimpleJson datasource plugin.
Results
The results were informative and nothing less than an eye-opener for me. Some devices, like computers, chargers, consume varying amounts of energy, and some devices, like lamps, monitors, consume constant energy. I might write a follow-up post just about the consumption of my computer running various workloads and applications. Here are few that I found interesting:
Desktop: Coding vs video games
Figure 3: Desktop energy usage: coding, standby, then, playing video games
- In the first half, the computer was used for coding using a simple text editor with light browsing.
- The drop represents the time it was put on sleep.
- The increase during the later part corresponds with playing a low graphics demanding game.
Monitor
Figure 4: Computer Monitor consumption: almost constant
- Energy consumption of my monitor is constant until I increased the brightness from 15% to 20%
Phone charging
Figure 5: iPhone getting charged using the stock charger.
- This curve is interesting - an exponential decay.
- Note the spikes too, maybe those correspond with the times the phone was picked up.
Conclusion
The energy consumption of the monitor is just 10% - 25% of the desktop energy consumption. So, although it might be still a good idea to turn off the monitor when things are running in the background, monitors are not the major consumers anymore (if they were at all earlier). It is interesting to note that the actual consumption is much less than the rated wattage of the devices.
It is also interesting to note the difference in magnitude of the consumption. So getting a gold rated PSU will have much more impact than having a more efficient iPhone charger. But none of this matters when you are sitting next to a 3KW space heater ;)
Footnotes:
I don't remember the exact statement very well but I suspect my teenage mind might have turned the scale from "monitor consumes a little more than desktop, to, monitor consumes a lot more" to suit its demands.
