[dscrdvrsc] <karero> @TexWiller great stats.
[dscrdvrsc] <TexWiller> ty, it's just an example; the goal, here, is to crunch as many data as possible to create meaningful views; something, imho, that is not so common in blockchain environment
[dscrdvrsc] <karero> In the last 100 block stats What happened to the missing blocks (minutes)?
[dscrdvrsc] <TexWiller> the query returns only mined blocks (where's the hashrate)
[dscrdvrsc] <karero> Can you also get out if the blockchain the transaction volume? Not sure if that’s really interesting since people move coins between addresses...
[dscrdvrsc] <karero> Ah so if the blick was not mined it’s minted?
[dscrdvrsc] <karero> Another interesting stat I find is the fluctuation of the network hashrate during the day. It significant. I guess it follows a pattern. Wonder why, people letting their machines run over night?
[dscrdvrsc] <TexWiller> @karero refresh the page, just added daily total TXs
[dscrdvrsc] <TexWiller> For the hashrate, I'm collecting detailed datapoint since today; for the historical, I still need help to calculate it from available datas
[dscrdvrsc] <karero> Very cool
[dscrdvrsc] <karero> What’s included in the tx volume public to public tx for sure. Public to private & private to public as well? Do private to private tx exist? I guess so, those I assume are excluded, aren’t they?
[dscrdvrsc] <elvinsophus> I think the network hash rate does follow a pattern. During some time of the day I mined more blocks than during the other.
[dscrdvrsc] <TexWiller> it's the count of txid fields
[dscrdvrsc] <karero> Amazing how constant the daily tx volume hovers around 2500 VRSC
[dscrdvrsc] <TexWiller> as now, the platform has all the fields from block (like getblock X) and transactions
[dscrdvrsc] <TexWiller> I hope to retrieve some community feedback to improve it; haven't found (or haven't be able to ) something to compare or to take as inspiration
[dscrdvrsc] <karero> The txid fields should include private to public, public to private tx, shouldn’t they?
[dscrdvrsc] <karero> For staking it would be very interesting to know the value of all funds in public addresses. Do people need to have their wallets online - or do you stake offline (the network stakes for you)? Is that something you could retrieve?
[dscrdvrsc] <TexWiller> I should be able to retrieve addresses balance but I need to import all known addresses into the node (as watchonly). It may some take a day or so to import all the datas


Now I have written a full, interrupt driven sketches for an arduino running some traffic signals. An extract is shown below:-
if ((_state == PHASE_GREEN) && (_phase_change == PHASE_CHANGE_TO_RED)) {
// On Green want Red
if (ran_min_green()) {
_state = PHASE_POST_GREEN;
_phase_change = PHASE_CHANGE_NONE;
_time_since_green_milliseconds = 0;
_time_on_current_state_milliseconds = 0;
if (debug_to_serial) {
Serial.println("Leaving Green");
}
}
}
However for this project, I do not need interrupts - so I using some simplicity on the timing. I also do not want the signals to cycle forever so I have added an END_SEQUENCE. Based upon the rectangle PCB With the following circuit, I put together a simple sketch. I borrowed the concept of using bits for each of the Red, Amber and Green from Paul Van Gelder
#define RED 1
#define AMBER 2
#define GREEN 4
#define RED_FLASH 8
#define AMBER_FLASH 16
#define GREEN_FLASH 32
Then I can define each sequence as follows:-
sequence[SEQUENCE_TYPES][MAX_STEPS][2] =
{
{ // Normal Traffic RAG
{RED, 3},
{RED + AMBER, 2},
{GREEN, 7},
{AMBER, 2},
{RED, 3},
{END_SEQUENCE, 1},
}
With some neat boolean logic
flash = 255; // or ~255 (0)
leds = sequence[s][current_step][0]
digitalWrite(RED_PIN, (leds & RED) | (leds & RED_FLASH & flash));
My first attempt, I was running low on memory for global variables. Which in the end caused the ATTiny45 to crash. The solution is to use PROGMEM - Store data in flash (program) memory instead of SRAM. Using PROGMEM is also a two-step procedure, it requires special methods (functions) to read the data from program memory back into SRAM, so we can do something useful with it. Some good hints from this sketch.
uint8_t leds = pgm_read_word_near( &(sequence[s][current_step][0]));
All solved ? Well no, Paul Van Gelder posted a change to Stop that Flash Jitter. Which worked very well:-

Russian petrol pump's bikini offer has Twitter in splits
While the owner of the Olvi petrol station in Samara must have female customers in mind while making the offer for some publicity
by IANSThe offer of free fuel to customers wearing a bikini by a petrol pump in Russia was nothing less than a bombshell, and many men took up the dare to benefit themselves.
While the owner of the Olvi petrol station in Samara must have female customers in mind while making the offer for some publicity, many males turned up in skimpy bikinis to get free fuel.
Twitter had a hashtag #BikiniDress on the issue. There were witty remarks from Twitter users. One said: "When you change your character's gender in a game in the middle of a mission".
Another pointed out: "Some dudes even went the extra mile with the heels".

A Twitter user said: "Me and the boys refuelling our government-issued T-34s". "They had to come in a group, to get fuel for their tanks, with the Russian anthem playing in the backdrop".
One was reminded of fire hazards by seeing pictures of men in bikinis.

5G Technology : From Smartphones To Smart Everthing
The term 5G denotes the next major phase of mobile telecommunications standards beyond the current 4G. Currently under development, 5G is about to revolutionize the world, allowing to create a future believed to be out of our reach.
The transition from wireless 4G networks to 5G networks may seem to be just another update as there are tens in the world of technology, but the 5G is a special case. Every generation of mobile network so far, including 4G, has been used to connect people, however the fifth generation will offer a wide connection between things and objects, such as people, cars, drones and IoT, creating a huge stream of data and changing our world forever.
An obvious response would be a faster network (5G should be 10 times faster than it’s predecessor), but speed is not the most revolutionary aspect. 5G is being built from A to Z to ensure a secure signal with low latency. This reliability is what makes the 5G a network for “things”, which would trigger a new wave of automation.
In a world that is now largely digitized, the field of automation is enormous. In the industry for example, we can imagine factories deploying machines and connected objects to make the manufacture much more efficient.The idea of a “smart city” is also very dependent on automation.
If we want to avoid dystopian traffic jams, we need sensors to manage the flow of traffic, predict problems and dynamically adjust signaling to compensate. To save energy, we need sensors to turn on and off the light in response to the presence of a car.
When 5G becomes a global standard, it should bring a better connection between all these components to encourage a system to work in a holistic way. Unlike all connected devices that currently populate your home.
5G migration continues to command industry attention and discussion. Strategy Analytics said that by 2025, 5G is forecast to reach 690 million connections and more than 300 million handset shipments. Guang Yang, senior analyst for Strategy Analytics, said, “5G network plans have developed well in 2016, driving an ecosystem that will put 7% of mobile connections on 5G networks by 2025.”

Runner that assumes a homogonous set of nodes. Now only support only node based limiting (although process limiting can be emulated by setting process_per_node=1 and max_nodes=max_procs). Threading model: assumes there could be multiple producer threads calling add_pipeline, e.g. if using a dynamic job submission model based on results of previous jobs. Pipelines and each Run in a pipeline are all executed in separate threads, so their notification callbacks execute in separate threads, and their threads must be joined before exiting. The stop and kill_all methods could be called from any of the producer, Pipeline or Run threads.

The Blair Witch Project (6/10)
In 1994, three young and inexperienced documentary film-makers set off into the Maryland woods to investigate the story of the Blair Witch, a creepy figure of local folklore, said to be responsible for disappearances and deaths over several decades. All that was ever found of them was the footage they shot. This material was edited and the result is presented here. It tells the remarkable story of how they became lost in the forest and were tormented by strange unseen forces. There's one often-overlooked aspect of this spooky tale that's worth bearing in mind... it's not true. Let's just let that sink in a moment. It's a story. They made it up. It didn't happen.
Some low-budget films have a structure or technical approach which flows from a single cost-cutting idea. The excellent 1998 Canadian science fiction film Cube was set in a huge maze of interconnecting cubic rooms. A set was constructed of one such room, 18 feet on a side, and that's where the whole film was shot. The Blair Witch Project takes a similarly simple and retrospectively obvious idea to make a virtue of necessity: the whole film is presented as the edited footage shot by the three documentary makers and all this material was recorded by the three actors playing the documentary crew. The actors were given a 16mm film camera, a Hi-8 video camera and sound recording equipment, and each day they were given some minimal direction and left to improvise a day's shooting. The footage was collected at the end of each day in exchange for food and the next day's story line. The real film-makers crept around the actors' tent at night producing scary noises and preparing strange artifacts for the increasingly uncomfortable cast to discover the next day. The originality of this idea has been questioned, with films such as Cannibal Holocaust and The Last Broadcast cited as earlier examples of the mockumentary approach to horror movies.
The nature of the film lends itself to confusion about the reality of the events depicted. When we see tired, hungry, cold and scared characters on the screen, we are watching actors, but we are watching tired, hungry, cold and scared actors. Many people seem to have had a problem grasping the idea that the film is a work of fiction. Feeding off the pre-millennial appetite for spooks and demons, the film-makers deliberately fostered this confusion by using the actors' names - Heather, Michael and Josh - for the characters and presenting the film as a true story in promotional material. The official web site, for example, provides extensive "factual" background material on the (completely made-up) Blair Witch story and the unfortunate trio. The story is also presented as truth in many of the unofficial web sites which fuelled interest in the film. These sites were supposedly produced by fans of the movie, but it has been suggested, although the film- makers deny it, that some were actually professionally-produced publicity sites masquerading as fan sites.
There is no violence or gore in the film (apart from a small lump of unidentifiable bloody matter), no special effects and no visible monsters or spooks - the story is told purely through the reactions of Heather, Michael and Josh to what goes on around them. The three performances are convincing, but it is hard to know to what extent we are watching acting or a recording of three very uncomfortable people. The story goes that the actors had to sign releases indicating that they would not hold the film-makers liable for any psychological damage they might suffer as a result of the harsh shooting conditions. In order to see the performances, of course, the characters had to film each other when they might have been expected to have more important things to do, such as make their documentary, find their way out the woods, or run around screaming. This is explained by the pushy Heather, who does much of the most personally intrusive filming and claims to want to record their experiences as well as make a documentary. I wasn't really convinced by this explanation, but how else could we have a movie to watch?
The film has so far made around $140,000,000 in the US - not bad for a movie that cost around $40,000 to make (although the distribution company that picked it up spent an extra $100,000 on the film, mainly on improving the sound quality). It is hard to know what the film's writer- directors, Daniel Myrick and Eduardo Sanchez can do next. They have made one of the most successful films of all time, and the money people will be throwing cash at them, yet they've made an unrepeatable freak of a film, with no evidence that they will have a clue about how to make another movie.
The Blair Witch Project is a triumph of marketing, and raises some interesting issues about what's real and what isn't in movies. The technical approach is novel, but this in itself isn't enough to sustain a feature film. There are a few creepy moments, and a the final scene is pretty chilling, but the scariest film ever made? Hardly. When the making and marketing of a film is more interesting than the film itself, you know there's something wrong.

The program pairs up 1-2 undergraduate students with a graduate student or professor mentor. Each pair will decide on a project to work on throughout the semester. All undergraduate mentees will write a 1-2 page summary and give a presentation at the end of each semester on what they have done/learned.
Mentors benefit since PURE is flexible with their schedules, providing them undergraduate researchers with the desired skill set and inspirations who make great early additions to a research team. The structure of PURE, including events such as the Research Presentations Workshop, also trains mentees about the discipline of engineering research.
“Undergraduate students will participate in a semester long project with his/her graduate mentor. Responsibilities may include:
- Drafting a goal statement at the beginning of the program
- Establishing an agreement for course credit for PURE via ECE 297 or CS 199 (mandatory for ECE students)
- Meeting weekly with the graduate mentor
- Completing learning/researching tasks
- Giving a presentation at the end of each semester
- Participating in PURE social events / talks
“Graduate students are encouraged to participate as PURE mentors. You are also more than welcome to provide us with suggestions and feedback. A mentor's responsibilities mainly include:

//global search dirs
//"GetExecutingAssembly()" assembly for app.config files
//global resolve assembly routine
//added support for resolving .exe assemblies referenced by "using mnamespace" directives
//Script config file (css_config.xml) contains SearchDirs property
instead of ExtraLibDir which is still supported but in a way obsolete
//fixed a but with loading assembly when compile only was executed (see bugs report.html)
using System;
using System.Reflection;
using CSScriptLibrary;
class Script
{
static public void Main(string[] args)
{
CSScript.GlobalSettings.SearchDirs += ";"+Environment.CurrentDirectory;
CSScript.AssemblyResolvingEnabled = true;
Assembly asm = Assembly.Load("GetExecutingAssembly()");
Assembly asm1 = Assembly.Load("hello");
}
}
Added another aliases for
//css_import directive:
//css_include and
//css_inc
They are equivalents of
//css_import <file>, preserve_main. These directives are logically similar to the
#include in C++.
Now you can specify script command-line arguments
directly from code.
The
//css_dbg directive allows controlling how the script is loaded in VS2005/VS2005E at execution
time. It includes type of the temporary project generated (console/winexe/library) and project debugging arguments.
Added new command line argument:
/co:<options>
Pass compiler options directly to the language compiler (eg. /co:/d:TRACE pass /d:TRACE option to C# compiler).
- css2cs.cs
This script converts the cassless C# into standard C#.
- setEV.cs
This script allows setting environment variable permanently by using
WScript.Shell COM object usually available from VBScript
- createShortcut.cs
Creates execution shortcut to the script file.
- lib.cs
Shows Script Library content.
- The format and name of the CS-Script runtime settings file (
css_config.dat) is changed. It is now xml file
css_config.xml.
- Added
HideCompilerWrnings option to control level of details in compiler output information.
- Added option for enabling /disabling the Advanced Shell Extensions from the configuration console.
Added InvokeInst method to the AsmHelper class to invoke instance methods. This functionality makes AsmHelper capable of assisting in all possibles dynamic assembly loading/executing scenarios.
Changed CS-Script directory structure
In order to simplify CS-Script deployment architecture Debug folder has
been moved from the CS-Script root directory to the
root/Lib.
Note: If you are upgrading from any previous version of the CS-Script the content of the previous
Debug folder is moved to
Lib/Debug/Backup.

Now that you've created a Intel Edison temperature monitor that prints to the LCD screen ( often called the edge device in these labs ), we will begin taking steps to integrate this edge device onto the Intel Iot Gateway's network. The goal is to move the administration and configuration of the edge device to the gateway. This allows businesses to manage a large deployments of IoT devices in a scalable manner.
We will begin by creating a database that will track the status of the IoT edge network. Then we will demonstrate how to make a sensor publish data to the edge netowrk by writing a NodeJS server that publishes the temperature data to the Intel IoT Gateway. Likewise, we will also write software to allow the LCD screen to be controlled on the edge network.
The techniques learned in this exercise can be applied to any network enabled sensor or actuator to integrate them into an IoT edge network.
Part 3
This server is to be installed on an edge device and it has two purposes. First, to announce its presence on the edge network when it comes online and second to publish sensor data to the Intel Iot Gateway and the rest of the edge network. Both the announcement and the publishing of data will happen over MQTT.
In this exercise, you will write an MQTT server that announces its presence and publishes temperature data to the edge network. Be sure that you go to the links in the reference section, they'll provide you with the information to do the lab.
Here are the steps in this exercise:
Create a project named temperaturePublisher
We need an NPM modules for this labs. Add the MQTT NPM package to the dependencies section of the package.json file. The temperature sensor module is already installed on your Intel Edison.
$ npm install mqtt -g
$ npm install intel-commerical-edge-network-database-models --save
and in you package.json
type in these dependencies
Import the MQTT and the jsupm_grove packages with the require statement.
Initialize the temperature sensor. See the temperature sensor documentation on the Intel Developer Zone.
Connect to the Mosquitto database. See the MQTT module documentation.
Write an event handler that responds to the MQTT connect event. In this event handler, publish an announcement that a new sensor is available on the edge network.
Publish a sensor announcement from within the MQTT connect event callback. The sensor announcement should be a JSON string. Be sure that you remember the JSON strings format because you will need to receive the announcement and save it to the database in the next lab.
The announcement should follow the sensor schema format.
Inside the event, write a setInterval function that publishes the sensor data. The setInterval function is NodeJS function that lets you call a function on a timed interval. See Timers Node.js v4.1.1 Manual & Documentation for more information on setInterval
The temperature data should follow the data schema format.
Publish the data to the sensors/temperature/data
MQTT topic.
Part 4: Provision and Control Actuators on an Edge Network
In this exercise, you will create a restful HTTP API to control an actuator deployed on an edge network. Use the Express NPM module to implement a Restful HTTP server control the LCD display.
These are the actions that the actuator can perform.
Create a lcd-server
directory and change into that directory. cd lcd-server
Install the NPM Express module.
$ npm install express --save
This is the implementation of the GET /lcd/backlight
.
Implement the POST
and DELETE
for /lcd/backlight
, as well as the GET
, POST
and DELETE
for /lcd/text
.

Guess what lettet I'm thinking of


Boston, MA | LinkedIn |<EMAIL_ADDRESS>Below are some of the questions I find interesting, mostly outside of heavy industry and machine learning. Relevant reading recommendations always welcome.
What are the externalities of income inequality? What is the marginal social cost of inequality? Can this be quantified?
In spite of some research on the subject, I haven't found a source that quantifies the costs of income inequality. It seems that most policy recommendations are based more on "animal spirits" than on estimated costs.
I'd be interested in the list of negative externalities: social unrest, breakdown of institutional trust, unproductive behaviors, etc.
What are the marginal social costs of greenhouse gas emissions?
Working in energy, this question is often top of mind. What is the ideal tax on GHG emissions? I have seen some brilliant efforts to quantify the discount rate over very long periods, based on relative pricing of leasehold and freehold properties in the UK, but I have yet to find research that quantifies with present value of the GHG emissions.
In my view, with the long term discount rate approximated, we only need to know the approximate marginal social cost of a tonne of carbon-dioxide emissions to implement an optimal tax policy. Unfortunately, this seems to me an unusually difficult question: how do emissions affect property values in Amsterdam vs. Fairbanks, Alaska? Do carbon dioxide emissions in New Zealand affect property values in Spain? Over what period will these property value adjustments take place due to emission? Climate systems are difficult to model!
What is the single policy change in the US that would create the most value?
Value here defined in the basic economics sense of the word, namely, the price an individual is willing to pay, less the price at which the provider is willing to provide such a service, then aggregated across all units of the goods or services delivered. For example, although citizens may have a high willingness to pay for comprehensive healthcare services, the price at which providers are willing to provide that care may exceed the willingess to pay.
What is the policy adjustment that could be made to drive the most value? Does it have to do with retirement accounts, taxes, education, healthcare, or something else? How might you attack this problem and identify a solution? To a first order approximation, the policy change should be Pareto efficient, that is, not making any individual worse off.
What countries are best in the world in each major policy area?
I'm particularly curious about healthcare, the eradication of poverty, technology development, schooling, retirement programs. Generally, which countries are best in class for all major public policy issues? Can these policies be replicated in the US, or are they only possible because of idiosyncratic factors? I would love to take a field trip to each of the chosen countries to learn more about what makes them so effective. What measures should we use for effectiveness?
What thirty year period in world history generated the most real wealth on a per capita basis? What about the highest level of per capita growth?
Thirty years is semi-arbitrary—long enough to avoid the impact of business cycles, including recoveries. What were the drivers of growth in these periods? What are we missing today? What could be replicated?
What concepts or practices can be implemented to free up the most personal time?
As I get older, I appreciate time more and more as the binding constraint. I'd imagine the answers are specific to each individual, but what are some simple practices to eliminate poorly-spent time or create more time generally. Where is time mis-allocated? What steps can I take to free up more of it?
For one week, I used a time tracker to log every minute of my day, and was surprised how much time was spent in-between tasks (traveling between meetings, for example) and how difficult it was to set four hours of interrupted work.

olm.USGS package
This package contains functions for retrieving and processing data from the USGS National Water Information System database (NWIS). Using these modules it is possible to retrieve water quality data, discharge data, and site metadata. These data are then converted into Pandas data objects and stored in pickled and spreadsheet format for later usage. The package also contains functions for processing the Pandas data objects through the USGS water chemistry code PHREEQC. For this, an installation of PHREEQC is required.
The most typical entry point is to use the convenience function runWQXtoPandas
. This function can be used from within python by importing it from the olm.USGS.WQXtoPandas
module. It can additionally be used from the command line using:
$./WQXtoPandas.py <name of input xls file>
Most functionality can be controlled from within the Excel file. A template is provided with the olm package in the examples directory. The examples file also contains some brief code illustrating how data can be read in from the pickled outputs of WQXtoPandas
and plotted.

A large document requires a lot of input. Rather than putting the whole input in a single large file, it's more efficient to split it into several smaller ones. Regardless of how many separate files you use, there is one that is the root file; it is the one whose name you type when you run LaTeX.

The com.jme.light
package contains various lights that can be placed
in a scene.
There are 3 types of lights currently supported in jMonkeyEngine:
- Point Light - Point lights emit from a certain location and have a certain influence radius (optional)
- Directional Light - Directional lights will always appear to emit from a certain direction
regardless of an object's position
- Ambient Light - Ambient lights have no location or direction;
they simply emit a constant color that is applied to the entire scene


PLANET SICK-BOY: http://www.sick-boy.com
Tim Burton puts his unique stamp on Washington Irving's classic short story The Legend of Sleepy Hollow, and the result is a genuinely frightening and campy picture that's funny in all the right places. Though changes have been made to Irving's yarn, viewers will likely appreciate Burton's dark sense of humor, as well as Hollow's fantastic visual effects.
Hollow opens with a fast, bumpy stagecoach ride through the woods near Albany, New York. The passenger (an uncredited Martin Landau) peeks his head out, notices that the driver no longer has his, and leaps from the moving carriage. As he runs through the woods and into a cornfield, the man comes across a creepy scarecrow that could be an early ancestor of Burton's Jack Skellington. Terrified, he stops, turns and is decapitated by a headless horseman.
Flash to a 1799 New York City courthouse, where the judge impatiently listens to Constable Ichabod Crane's (Johnny Depp, The Astronaut's Wife) customary lecture about the importance of collecting evidence from the scenes of crimes in order to fairly prosecute guilty parties. Tired of his liberal thinking, the judge sends Crane to investigate three bizarre murders in an isolated Dutch farming community called Sleepy Hollow in Upstate New York. So Crane, somewhat of a forefather of modern forensic science, packs his bags with strange chemicals and what looks to be nightmarish homemade dental tools.
Once he arrives in Sleepy Hollow, the town's leaders give Crane the lowdown on the murders. Each victim was beheaded, but the heads were never found. Worse yet, Crane learns that the killer is believed to be the ghost of a Hessian trooper (Christopher Walken, Blast From the Past) who was himself beheaded twenty years earlier, leaving his spectre to ride a mighty black steed through the West Woods in a nightly quest for his skull. Crane, a weak-hearted ‘fraidy cat prone to fainting spells, realizes he may be in way over his head.
There are a few sticky points, namely the inclusion of Crane's nightmare flashbacks to his childhood, where his buxom mother (Lisa Marie) dabbled in witchcraft. This appears to be added only to show off Marie's fantastic rack – she's Burton's real-life girlfriend and has appeared in his last few films. But this transgression can easily be overlooked, however, because…well, because of the aforementioned rack. Burton's film seems pretty true to its source, right down to Katrina Van Tassel's (Christina Ricci, The Opposite of Sex) `plump as a partridge' stature to the name of Crane's dusty horse (Gunpowder). Burton even one-ups his predecessor, using the twisted, gnarled limbs of The Tree of the Dead as the Horseman's home.
The major change to Irving's work concerns Crane. In the book he was a kindly schoolteacher and musician, and is physically described as follows:
`He was tall, but exceedingly lank, with narrow shoulders, long arms and legs, hands that dangled a mile out of his sleeves, feet that might have served for shovels and his whole frame most loosely hung together. His head was small, and flat at top, with huge ears, large green glassy eyes, and a long snipe nose, so that it looked like a weathercock perched upon his spindle neck to tell which way the wind blew. To see him striding along the profile of a hill on a windy day, with his clothes bagging and fluttering about him, one might have mistaken him for the genius of famine descending upon the earth, or some scarecrow eloped from a cornfield. His sharp elbows stuck out like grasshoppers'.'
Doesn't exactly make you think of Johnny Depp, does it? Howard Stern, maybe, but not Johnny Depp. Irving's remarkably vivid representation of the protagonist stood out in my memory more than any other part of the original work - it's probably the best description I've ever read. In the text, the Horseman's cranium was blasted off by a cannonball in a nameless Revolutionary War battle. Interestingly, the script does include a `woman in white' that lived in the haunted woods, referring to one of the many legends Irving's townsfolk believed in his story.
In Irving's account, the story was told first-person after Crane's encounter with the Headless Horseman. Here, Burton and his writers (Andrew Kevin Walker of Se7en fame and special-effects specialist Kevin Yagher) have made the film into more of a Scooby-Doo murder-mystery, and the baddie is nearly as easy to finger. For a few minutes in this film, it seemed like the Horseman was turning into an unstoppable clichéd modern horror figure, like Freddie or Jason. The Horseman's battle with Crane and Brom Van Brunt (Casper Van Dien, The Omega Code) easily puts any skirmish in The World is Not Enough to shame.
Indescribably beautiful, from Danny Elfman's score to Emmanuel Lubezki's (Meet Joe Black) amazing cinematography to the breathtaking technical design work from the team responsible for Fargo, Kafka, Aliens and Gattaca, Burton's film captures the mood and feel of Irving's short right down to the eerie wooden bridge and the perpetual fog that seems to constantly roll through the gloomy town. And you can't help but think about Burton's Gotham in Batman when Hollow shows a view of 1799 New York City.
As a side note, the closing credits list a Conrad Hall as the director of photography for the New York unit of the film crew. I have been unable to confirm that this is the same Conrad Hall that was nominated for Best Cinematography at last year's Oscars (for A Civil Action), as well as an early favorite for this year's ceremony (American Beauty).

TANGO ARGENTINO A film review by Max Hoffmann Copyright 1993 Max Hoffmann
Rating: 10.0 (A, ****) a "must see"
IN A NUTSHELL: Not to be confused with the B'way show of the late 80's, this wise and winning film has the off-beat humor of BREAD AND CHOCOLATE and the heart-wrenching personal involvement of NIGHT OF SHOOTING STARS, but resembles neither of them in style or content. It brilliantly portrays the miracle of rebirth that can happen when the elderly and young are thrown together, and left to their own devices to create a real "family."
Date Released: not yet (no distributor) Country of Origin: Yugoslavia/Serbia Running Length: 1:33 Rating: none.
 I'm doubly burdened with such a mission by TANGO ARGENTINO, as there is no distributor. (North American premiere, Sun May 2, 1993 @ San Francisco Film Festival.)
Set in that brief golden bubble of time, between the fall of Communism in Yugoslavia, and the outbreak of the current bloody Civil War the movie was made almost entirely in Belgrade (now in Serbia). the film beautifully portrays the breakdown of one family, and the wondrous creation of a new one. Director Goran Paskaljevic chose 12-year Nikola Sarkovic from over 800 boys. Their teamwork has brought one of the year's most compelling performances to the screen. The film was completed in Aug 92, only days before the escalation of the bloody civil war in Serbia that now makes local creation of *any* films impossible. This is one film (should distribution occur) that you simply can not afford to miss viewing.
Nikola plays a gritty young capitalist-wanna be. He has far more sense and maturity with money than either of his parents, (his self-obsessed mother, Ina Gogalova, or philandering father, Miki Manojlovic). While his father dreams unrealistically of building a home based on income from being a wedding musician, Nikola dreams of getting a pop corn machine at the race track, so his family can make "real" money. The boy has gradually assumed many of his parent's adult responsibilities. He helps relieve his mother, by caring for her elderly charges, and even surreptitiously prompts his father with the right things to say to overcome serious marital rifts based on the father's philandering.
After his father gets a promotion in a music academy, with strings attached, Nikola steps in to center stage to hold things together. He must care for the three elderly charges his mother runs errands for (she's in Bulgaria seeking a cure for the ailing sister) *and* he must take on two new charges, relatives of his father's boss. Nikola has already grown close to Senor Julio Popovitch (brilliantly portrayed by former Yugo mega pop singer, Mija Aleksic.) Nikola finds a deep friendship with the spunky old Tango singer who refuses to "give in," even though he's virtually bed-ridden. In the director's talk after the screening, Paskaljevic revealed that the ailing Aleksic hadn't been able to work for 7 years. He was only allowed to work for two to three hours a day, with his doctor in attendance. With Life imitating Art, this wonderful performer grew stronger and stronger as the film progressed, and his doctor's new "prescription" is for Aleksic to make more films!
With the company of a dog he's inherited from a recently deceased "client," the pragmatic Nikola decides to simultaneously baby sit all of his elderly charges by bringing them together in a friendship club. Therein the magic of this film begins. Like nearly dry flowers in a spring rain, these wonderful old people "bloom" through friendship, romance, and a new-found sense of purpose. The gift of Goran Paskaljevic's direction prevents this from turning into sappy, sentimental sop like SMALL CHANGE. In a sense, each of Nikola's charges finds their own "tango," or dance of life. The film follows a path pitted with the very cul 'd sacs and dead ends that await any of us cursed with living long enough to become a "bother" to our adult children.
Much of the film's freshness comes from a deft script and Zarkovic's no-nonsense portrayal of the determined twelve-year-old. Far from being the lovable "artful dodger" type of moppet most of us were weaned on in countless Disney films, this is a pint-sized "adult" with a mission. He'll stop at nothing to build a stable financial base for his family. Like many work-a-holic adults, he's become so enmeshed in enabling others, that he's forgotten how to follow his own bliss. Only briefly, near the end of the film, (when we see Nikola frolicking nude on a Montenegro beach under the loving, watchful eyes of his "tango" friend), do we see him act freely and fully as a child. While his "real" family crumbles around him, he unknowingly brings together a warm and nourishing "extended" family. This family will touch your heart and stay with you a very long, long time.
Warning: you may leave the theatre wet and achey, from body constrictions and weeping that follow the sea-like emotional swell of this film. But you *will* leave the theatre reaffirming that, even under the shadow of war or domestic violence, there are always a few rare souls who can and *will* find a way to build true "family values," with or without their blood relations. That knowing is the film's ultimate gift.

The world has never before seen such high levels of productivity – even in France with our 5 weeks of vacation – and it is very much a consequence of the digital revolution and the automatization of many tasks. But the side effects of this faster work pace are not always welcome: burnout, depression, lack of purpose… Is being “sick on the job” the scourge of our age?
One thing’s for sure: a good paycheck is no longer enough to attract and retain the best talent. And companies know this: chief happiness officers, stress management coaches, and wellbeing programs are emerging to improve happiness in the workplace. So, what is actually at stake?
Happiness at work, the key to increased productivity?
Researchers from the University of Warwick in the UK have actually validated the theory. In 2014, Pr. Andrew J. Oswald, Pr. Eugenio Proto, and Pr. Daniel Sgroi published the striking results of their study: happy people were found to be 12% more productive, while unhappy workers proved 10% less productive. According to the three economists, “human happiness has large and positive causal effects on productivity. Positive emotions appear to invigorate human beings.”
What is true for individuals is all the more true for organizations. Companies that invest in employee support and satisfaction tend to succeed in fostering happier workers. And happy workers tend to work better with others, to have more energy, to be more creative, to fix problems instead of complaining about them, and to make better decisions overall.
The proof is in the profit. In 2005, Jerome Dodson, the founder of Parnassus Investments, added a new branch to his activities: the Parnassus Workplace Fund, a mutual fund that invests exclusively in large American firms proven to have outstanding workplaces, where employees are really happy. The kinds of firms that “genuinely cared about their employees as people, not just hired hands.”
Dodson scouted the country, not for the most promising companies, but for the companies that treated employees with profound respect and offered them ongoing training and personal development. Other criteria included:
- Providing a meaningful form of profit sharing
- Offering healthcare and retirement benefits
- Being supportive of working mothers
Happiness pays! To Dodson’s delight, the Parnassus Workplace Fund proved immediately, enormously, and enduringly successful. Since the fund’s inception and for 8 years, it “has had returns over 4% better than the S&P Index every year.” I’m sure we’d all like to get the same yield!
(For those of you who are not familiar with market valuations, the Standard & Poor’s 500, is an American stock market index based on the market capitalizations of 500 large companies with common stock listed on the NYSE or NASDAQ. Now you know.)
So when the latest Gallup study tells you that “only 13 percent of employees are engaged at work worldwide” it makes you wonder why happiness in the workplace isn’t a higher priority.
How do you boost wellbeing at work?
After sharing those results, you must be wondering: how can I boost employee engagement and happiness in my company?
Well, there’s good news and bad news. The bad news is: you cannot impose happiness on your employees. They have their share of responsibility in their own happiness. However, you can still set up ground rules and working conditions that will help your employees and teammates blossom.
Develop a culture of trust and transparency…
… where your employees can share their doubts and flaws, ask questions, challenge one another.. Keeping people afraid of failing or of showing weakness is the best way to hinder creativity. Your choice.
Show gratitude and value positive intelligence
Lead by example. To set up a culture of gratitude and kindness, just display these qualities. If you are convincing enough, your teammates will follow your lead.
Foster empowerment and accountability
To stay engaged, a worker needs to feel that his job matters, and to be recognized for it. Empowering each individual to carry out his or her own tasks, and praising the results is the best way to boost employee engagement – which doesn’t mean disparaging them should they need help.
Favor breaks and downtime
Contrary to what most people may think, procrastination is actually good for productivity. While at ease, our brain enters its default mode and starts processing and sorting out information. These default mode phases are essential to our brain. Promoting breaks and relaxation will boost your teammates’ productivity and creativity. It will also lower stress and frustration. Once again, I’d advise you to lead by example. Take a real lunch break and invite your teammates to join you. Take the time for coffee breaks and talk about anything but work. You can even set up a space to meditate, nap or do some yoga.
Launch a wellness program
Set up a healthy lunch or snacks program, sponsor gym membership, dedicate a room to yoga or fitness… Did you know that exercise actually stimulates endorphins (endorphins are neurotransmitters that induce a feeling of euphoria) (what better way to get happy?).
Now it’s your turn to be creative. What are your top tips for improving well being at your workplace?

Since 2015, I spend short of two hours each day commuting to work and back (train + bike). Listening to podcasts and audiobook have since become part of my daily routine and my main source for learning about topics outside my field of research. I find podcasts large bandwidth means of scholarly communication. Since 2017, I have started producing some podcasts of my own. I am for always indebted to Lex Bohlmeijer for his outstanding Goede Gespreken(nl) and kindly giving me some crucial advice and encouragement for the start.
Podcasts I have produced
The Universtiy Cooperative Workshop
I was one of the organizers of the first University Cooperative workshop on May 14th 2019, at Utrecht University. In this workshop participants were introduced to the issues, the concepts, and successful examples of governing common resources. They also investigated two cases related to the university and knowledge dissemination. This podcast reports on this workshop.
The Road to Open Science
When the open-science taskforce was formed at the Utrecht University to come up with a plan to promote open science practices, I was invited to represent the Utrecht Young Academy. We soon mentioned some resistance for a wider embrace of such practices, including fear, misinformation, and persisting old culture. This motivated some of us at the Utrecht Young Academy to start the Road to Open Science podcast together with our colleagues at the university library and the Open Science Community Utrecht. Our main goal was to communicate the basic principles of open science and engage in (sometimes difficult) discussions such as credit, culture, and vested interests.

- R2OS-Ep3, Academics in Charge
- R2OS-Ep4, The Untapped Potential
- R2OS-Ep5, With Cameron Neylon on Collective Action

// Add a `data-view-*` attribute
<input data-view-hello-world>

<input data-view-hello-world="Angela Merkel">

And for additional ✨ it parses JSON-encoded values from that attribute into a proper object for you:
<input data-view-hello-world='{\"greeting\":\"Guten tag",\"name\":\"Angela Merkel\"}'>

This gives you the power to create reusable components that can be "called" from your HTML with their own properties.
Viewloader provides freedom and flexibility to focus on encapsulating functionality within a minimal framework.
Viewloader is plain JavaScript; it doesn't have any dependencies.
See the Pen Hello Viewloader by icelab (@icelab) on CodePen.
Using npm:
npm install --save viewloader
Using yarn:
yarn add viewloader
Using unpkg:
<EMAIL_ADDRESS>var manager = viewloader(views, scope, includeScope);
You can call the views for an initialised instance:
manager.callViews();
Call the reset functions for an instances called views:
manager.resetViews();
Call the destroy functions for an instances called views:
manager.destroyViews();
You can customize and reuse Viewloader components by providing different properties to each instance, through the data-view attribute.
In this example we have components that change the background color of another element. Since color is the only thing that changes, we can send the color in as a parameter and use the same component multiple times.
Let's create the color changer Viewloader component.

Finally we bind the component to the DOM nodes, by adding the data-view attributes with the various colors.

1

2

3

4

That's it! You can see a live version of this example.
See the Pen Box of colours - Viewloader by icelab (@icelab) on CodePen.
Viewloader can be scoped to specific elements, allowing it to be used only in specific parts of the template or to be applied only to new DOM elements.
You can pass in a boolean flag as the third parameter to indicate if the scope gets included or not in the set of executed views.
In this example we will show how to scope a component with Viewloader
We have two boxes, a "main" box and an inner box. The inner box represents the "target" element.
Let's create a simple Viewloader component that changes the border color of our boxes.

We select an element to be the starting point of our scope and pass it as the second argument to the `viewloader` function. The third argument is a boolean indicating if the element is included in the scope or not.
It's worth remembering that the false scope is the default Viewloader behavior.
Last but not least, let's add the data-view attributes to set the border color.

Include scope

Exclude scope

The border that changes color depends on the scope you pass; the scope option gives you flexibility in how you use each component.
That's it! You can see a live version of this example here.

This seems to be an industry-wide favourite at the moment:
1
2
3
4
5
for (var i = 0; i < 4; i++){
setTimeout(function(i){
console.log(i);
}, i*1000);
}
where the directions say print out 0, 1, 2, 3 1000 milliseconds (or, 1 second) apart.
But why won’t this code obey? What does is it do? The code as is will print undefined four times, 1 second apart. Why not the 0, 1, 2, 3 at 1 second apart?
It’s because of block scoping and hoisting (and a few other things). Let’s quickly go over these two topics. In Javascript, a new scope is declared when the {} brackets are written in a function. For example:
1
2
3
4
5
6
7
var x = 11;
var foo = function() {
var x = 99;
console.log(x);
}
foo(); // --> 99
When function foo is invoked, it will log the value of x. It will log 99 because it is logging the value of x inside the scope of the foo function, what is inside the {} brackets. So what happens when we log the value of x outside the function foo scope?
1
2
3
4
5
6
7
var x = 11;
var foo = function() {
var x = 99;
console.log(x);
}
console.log(x); // --> 11
You guessed it, because we are not logging from inside the function foo scope, we are getting the value of x in the scope of the console.log statement on line 7, which in this case the global, which is x = 11 on line 1.
The other topic, hoisting, is when variable declarations are brought to the top of its scope. To be very explicit, only the declarations are brought to the top of the scope, not the initializations (what the variables are equal to). Hoisting is one of those Javascript topics that devs overlook because it seems redundantly obvious, until your code is breaking, then it’s important…ly annoying.
If you have just the one line of code, what do you think the console will say? It’s not undefined, but listed as
1
2
console.log(y);
// --> ReferenceError: y is not defined;
This is because y was not declared at all.
But if we had:
1
2
3
console.log(y);
var y;
// --> undefined
The console would say undefined. Here, y is declared and brought to the top of its scope. So the program recognizes y as a valid variable in the program, it just hasn’t been initialized with any real value.
And when I say the declarations get hoisted and NOT their initializations, that is why the following is still undefined.
1
2
3
console.log(y);
var y = 8;
// --> undefined
Let’s combine the two concepts now:
1
2
3
4
5
var x = 11;
var foo = function() {
console.log(x);
}
foo(); // --> 11
Here’s the other great thing about scoping. It takes on a one-way street mindset. When invoking the foo function, x is not defined or declared inside the foo function, so no declaration of x is ever hoisted to the top of the foo function scope. So what scope behavior will do is jump to the next outer scope looking for the value of x, which is why it logs 11 from line 1 here. I mention it’s a one-way relationship because when searching for values of variable the code goes from most inner scope to outer. Outer scopes will never reach into inner scopes for values.
What if we declare x inside the foo function but not initialize it? What do you think will log here?

var x = 11;
var foo = function() {
var x;
console.log(x);
}
foo(); // --> undefined
It’s logging undefined because within the foo function scope, is has been declared (not initialized with a value) but it does exist, so the log is undefined.
Knowing all that, let’s take a look at the original question again:

2
3
4
5
for (var i = 0; i < 4; i++){
setTimeout(function(i){
console.log(i);
}, i*1000);
}
So because of block scoping, the variable i inside the function on line 3 is different than the i in the for loop. It’s just deceptive because they are named the same letter. To see what I mean, let’s change the i’s to something else on lines 2 and 3.

5
for (var i = 0; i < 4; i++){
setTimeout(function(z){
console.log(z);
}, i*1000);
}
The same thing happens here. Undefined is printed four times, 1 second apart. So whether it’s i or z or any other parameter name, no value is sent into the anonymous function as an argument. But the reason the milliseconds are correct is because the i on line 4 is in the same scope as the for loop.
To test your knowledge of scoping and hoisting, what’s happening here?:

for (var i = 0; i < 4; i++){
setTimeout(function(z){
console.log(i); // when we change this back to i
}, i*1000);
}
// --> four times
// --> 4
// --> 4
// --> 4, all 1 second apart
The for loop runs from 0 to completing at 4 by the time any of the setTimeout’s go off. That is why we print the last number in the loop, 4, four times in the end. In Javascript there is also something called a Call Stack. It’s the queue of tasks the Javascript runner will execute in what ever order the tasks arrive in the queue (like at the ice cream shop, no cut-sies). Since a setTimeout is always going to be queued up for some time later (it’s in its nature to be put on the backburner, look at its name), the for loop is prioritised. Here, i is indeed defined because it looks to its outer scope (the scope that holds the for loop) for a value of i. But because at the time any of the setTimeout’s start executing it will look to its outer scope for i, i has already reached its final stage, 4.
 How do we pass each iteration of the variable i into the setTimeout? Well, there’s at least two ways. I’ll go into the two I know.
The first way is with the .bind() method. The .bind() is a useful way to capture a very specific instance of something, in our case, the progression of i. In this particular example, the .bind() method takes at least “two” parameters. The first argument of the .bind() method is always the context of which the function the .bind() method is attached to and will use when the target method is called. Typically the first argument is null or the keyword this. I’ll save the explanation for that in a different blogpost because you might get stuck in an infinite loop of babble :p but the important thing to note about .bind()’s arguments is everything after the context/first argument. You can pass any number of arguments into .bind(). In our case though, we are passing in every iteration of the variable i from the for loop:
1
2
3
4
5
for (var i = 0; i < 4; i++){
setTimeout((function(i){
console.log(i);
}).bind(null, i), i*1000);
}
it’s important to note here that the i’s on line 2 and 3 coincidentally are named i. Remember what we talked about earlier about different scopes within the {} brackets of a function declaration? The above code works the same if the i’s on lines 2 and 3 were a different name:
1
2
3
4
5
for (var i = 0; i < 4; i++){
setTimeout((function(m){
console.log(m);
}).bind(null, i), i*1000);
}
This code above outputs the same as when the m’s were i’s. By the way, when we said earlier that the first argument for bind could be null or keyword this, it didn’t actually matter in this particular case. If you set a completely different value in there, the code would still run the same. Try it with an empty object {} or a string.
Anyway, why’s the code behaving now? By binding the anonymous function inside the setTimeout to any context and passing in the i value as its only argument, we are “capturing” each value of i. Remember, the value of i on line 4 (both of them) are in the scope of the for loop because they are outside of the anonymous function declaration inside the setTimeout. Whether the parameter name on lines 2 and 3 are m, i, or oogaBooga its value becomes the argument passed into it.
The other way to make the code behave and print the successive values of i is using an IIFE, an Immediately Invoking Function Expression. Sometimes read as “iffy” or as my friends and I like to pronounce it as if we spoke French, an “eefay” :p Anyway, an IIFE does what you might think it does according to its name, it invokes itself immediately. Wrap the setTimeout in an IIFE and pass it the value of i, the i that will be in the same scope of the for loop.

for (var i = 0; i < 3; i++){
(function(z){
setTimeout(function(){
console.log(z);
}, 1000*i)
})(i);
}
The funky thing about setTimeout is that it is a method on the window object. When writing:
setTimeout(functionHere,timeElapsed)
the setTimeout method is calling what ever function passed into it (whether an anonymous function of a variable declaration elsewhere) after the amount of time that you passed in has elapsed. As in, that inner function inside the setTimeout is invoked “as is” with no arguments passed into it. Because we are trying to pass different things into this anonymous function inside the setTimeout, we need to get all fancy with IIFEs or .bind() in order to make it happen.
