If a function cannot return a value or throw an exception without blocking, it can return a promise instead. A promise is an object that represents the return value or the thrown exception that the function may eventually provide. A promise can also be used as a proxy for a [remote object][Q-Connection] to overcome latency.
[Q-Connection]: https://github.com/kriskowal/q-connection
On the first pass, promises can mitigate the “[Pyramid of Doom][POD]”: the situation where code marches to the right faster than it marches forward.
[POD]: http://calculist.org/blog/2011/12/14/why-coroutines-wont-work-on-the-web/
```javascript step1(function (value1) {
- step2(value1, function(value2) {
- step3(value2, function(value3) {
- step4(value3, function(value4) {
- // Do something with value4
});
});
});
});¶
With a promise library, you can flatten the pyramid.
```javascript Q.fcall(promisedStep1) .then(promisedStep2) .then(promisedStep3) .then(promisedStep4) .then(function (value4) {
// Do something with value4
}) .catch(function (error) {
// Handle any error from all above steps
With this approach, you also get implicit error propagation, just like try, catch, and finally. An error in promisedStep1 will flow all the way to the catch function, where it’s caught and handled. (Here promisedStepN is a version of stepN that returns a promise.)
The callback approach is called an “inversion of control”. A function that accepts a callback instead of a return value is saying, “Don’t call me, I’ll call you.”. Promises [un-invert][IOC] the inversion, cleanly separating the input arguments from control flow arguments. This simplifies the use and creation of API’s, particularly variadic, rest and spread arguments.

Abstract
The system development process started with inspiration from the natural world. Slime mold – a single cellular organism renowned for its ability to find the most optimal route to find the source of food was an initial driver of the design. During the development of the project initial ideas shifted towards a wooden, modular system which could be assembled and disassembled with ease. Timber planks of the same size would allow anyone to use and build the system.
3D model
The 3D model uploaded using threejs with data assigned for each element. To highlight data click on different parts of the model below.
Inspiration
Design initial inspiration came from slime mold.
“Slime molds are among the world’s strangest organisms. Long mistaken for fungi, they are now classed as a type of amoeba. As single-celled organisms, they have neither neurons nor brains. Yet for about a decade, scientists have debated whether slime molds have the capacity to learn about their environments and adjust their behavior accordingly.”

Initial form finding and exploration
Grasshopper form finding experiments.
Slime mold behaviour recreated in grasshopper
Algorithm applied to Ennepers surface
Volumetric shape achieved by using Cocoon
Structural analysis
Using KARAMBA 3d to get the better understanding of factors effecting structural performance.
Final fabrication approaches
Final ideas for fabrication was to either use steel plates as way to join pieces or to use the self-supported approach. The element used were 5909 4 x 4 cm wooden planks, 50 cm length for regular grid and 70 cm for reciprocal approach. After analyzing the steel plates approach, it was changed to custom plug and play nest-joint system. This action was done to make the fabrication as simple and easy as possible. As the grid consists of the elements of the same length and is based on tetra and octa-hedrons it has a finite number of joint types, which can be prefabricated or 3d-printed.

Customizing @view_function
¶
Since the @view_function
decorator must be placed on all view functions in your system, it’s a great place to do pre-endpoint logic. The decorator was intentionally programmed as a class-based decorator so you can extend it.
Django provide several ways to insert logic into the request process, so be sure to consider which is the cleanest approach for your situation: the approach here, middleware, signals, or another method.
Using Keyword Arguments¶
Although we normally specify @view_function
without any arguments, it can take an arbitrary number of keyword arguments. The following are some examples:
# the normal decorator
@view_function
# ensure the user has a role of "mentor"
@view_function(role='mentors')
# require authenticated access, set response type to text/html
@view_function(auth_required=True, mimetype='text/html')
Through a simple extension, you can access the parameters above and do custom logic–just before process_request is called.
Example: Authenticated Endpoints¶
Suppose your site requires authentication on nearly every endpoint in the system. Normally, you’d add Django’s @login_required
decorator to endpoints, like this:
from django.contrib.auth.decorators import login_required
from django_mako_plus import view_function
@login_required
@view_function
def process_request(request):
...
Rather than hope every endpoint gets marked with the decorator, let’s modify DMP’s view function decorator to require access by default. Create the following in a file called lib/router.py
:
from django.conf import settings
from django.http import HttpResponseRedirect
from django_mako_plus import view_function
import inspect
class web_endpoint(view_function):
'''Marks a view function in the system (with auth required by default)'''
def __init__(self, decorated_func, auth_required=True, *args, **kwargs):
self.auth_required = auth_required
super().__init__(decorated_func, *args, **kwargs)
def __call__(self, request, *args, **kwargs):
# ensure authenticated
if self.auth_required and request.user.is_anonymous:
return HttpResponseRedirect(settings.LOGIN_URL)
# allow the call to continue
return super().__call__(request, *args, **kwargs)
Then, use this decorator instead of the normal view function decorator. In fact, do a global search and replace of @view_function
, and replace it with @secure_function
.
from lib.router import secure_function
@secure_function
def process_request(request):
...
When DMP calls your view functions, it now runs lib.router.secure_function.__call__
. Our function redirects if the current user isn’t authenticated yet. If the user is authenticated, we call the super’s __call__
method, which runs the view function. Just like that, every endpoint in the system is protected by default. Yeah, you know you rock!
For endpoints that need to allow anonymous access, the auth_required
parameter signals that anyone can access the endpoint:
from lib.router import secure_function
@secure_function(auth_required=False)
def process_request(request):
# even balrogs allowed to pass!

Optimal Control - Motion Planning - Trajectory Optimization
Reinforcement Learning - Machine Learning - Legged Robots
I am a robotics researcher working in the intersection of model predictive control and machine learning for motor control in legged robots. The aim of my research is to enable robots to move everywhere. In particular, I am focused on the problem of loco-manipulation tasks since it combines the main challenges in robot mobility. My research combines the formalism of model-base approach with the exploration of vast robot’s data.
I completed my PhD on “Planning and Execution of Dynamic Whole-Body Locomotion on Challenging Terrain” in April 2017 in the Dynamic Legged System lab at Istituto Italiano di Tecnologia. After that, I served as Research Fellow from April to December 2017. During this period, I mainly contributed to planning, perception and control framework for legged locomotion on challenging terrain. I also designed a considerably part of the HyQ’s software framework. In my career, I have spent fruitful time in different European research institutions: IIT (Genova), ETH Zurich, LAAS-CNRS, The University of Edinburgh and Tha Alan Turing Institute.

Tcl_NewIntObj and Tcl_SetIntObj set the object to have the integer value given by intValue, Tcl_NewLongObj and Tcl_SetLongObj set the object to have the long integer value given by longValue, and Tcl_NewWideIntObj and Tcl_SetWideIntObj set the object to have the wide integer value given by wideValue. Tcl_NewIntObj, Tcl_NewLongObj and Tcl_NewWideIntObj return a pointer to a newly created object with reference count zero. These procedures set the object's type to be integer and assign the integer value to the object's internal representation longValue or wideValue member (as appropriate). Tcl_SetIntObj, Tcl_SetLongObj and Tcl_SetWideIntObj invalidate any old string representation and, if the object is not already an integer object, free any old internal representation.
Tcl_GetIntFromObj and Tcl_GetLongFromObj attempt to return an integer value from the Tcl object objPtr, and Tcl_GetWideIntFromObj attempts to return a wide integer value from the Tcl object objPtr. If the object is not already an integer object, or a wide integer object in the case of Tcl_GetWideIntFromObj they will attempt to convert it to one. If an error occurs during conversion, they return TCL_ERROR and leave an error message in the interpreter's result object unless interp is NULL. Also, if the long integer held in the object's internal representation longValue member can not be represented in a (non-long) integer, Tcl_GetIntFromObj returns TCL_ERROR and leaves an error message in the interpreter's result object unless interp is NULL. Otherwise, all three procedures return TCL_OK and store the integer, long integer value or wide integer in the address given by intPtr, longPtr and widePtr respectively. If the object is not already an integer or wide integer object, the conversion will free any old internal representation.

To Vectorise or Squeegee / The Creative Conference / SXSW: Data Visualisation for Social Change / SXSW: Everything is a remix / SXSW: "Design for Hackers" Kadavy: Designing for White Space / SXSW: Community-centered design / Troika
Troika
Throughout the State of Design festival, The Wheeler Centre hosted a series of Skype talks with international creatives, allowing Melbourne audiences access to studios otherwise geographically impossible. The second talk in the series was trans-disciplinary UK studio Troika, an evening ending in keen debate.
Despite the complexity of their projects, Troika aren't concerned about failing. "You have to fail fast, rather than worrying about failing at all", explained Sebastien Noel, "The earlier you fail, the sooner you can improve". Joined by Conny Fryer, the two-thirds of Troika responded with sincerity and warmth to questions from panelists Fleur Watson, Gyungju Chyon, Paul Fuog, Pheobe Whitman, Simon LeAmon and later, from the floor.
Troika is renowned for creating objects and installations formed within the intersection of architecture, art and technical invention. Together with scientists and engineers, these collaborations of polished skill and cold materials turn into sensitive, immersive, digital experiences that evoke emotional responses from the viewer - who they admit to being one of their only limitations. "Client's do not come to us with briefs, only context. Context is our brief," explained Noel, stating that corporate commission or not, they aim for real-time relationships with context, resulting in work reflective of our technologically reliant times.
Questions from the audience and panel consistently circled technology as the topic of the night, the technical and corporate sleekness of their pieces supposedly throwing into question their work as art. Yet Fryer played it down, explaining that technology is merely a tool - one that lends itself fluidly to creating experiences, and it is experience that is key. In their hands, technology has an expressive capacity and, while mechanically complex, Fryer insisted the idea must always be simple - often translating and reconstructing what they find inspiring in natural phenomena. The results, she said, speak volumes about our relationships with both.
With the Skype call ended, the post-panel discussion quickly became divided. Some panelists felt their progressive approach needed to be culturally valued, but how to value their work, when it is at once art, design, corporate, public and experimental? Others countered that Troika's value transcends galleries and tradeshows - it speaks to people sensuously, thoughtfully. The night ended with a grounding statement - does it really matter? Where experience is the crucial component, is it necessary to draw a line between disciplines? Is it even relevant to what they create?
Perhaps not. Troika doesn't seek out the neatest piece of new technology and construct around it - nothing is created for its own sake. They make intuitive connections, mirroring the ever-shifting identities of beauty, nature and machine.

Access Control Lists (ACLs) with FD.io VPP¶
This section is overview of the options available to implement ACLs in FD.io VPP. As there are a number of way’s to address ACL-like functionality, it is worth a separate survey of these options with some commentary on features and performance
All performance numbers and examples from this document are reused from the FD.io CSIT v19.04 performance report All information and performance is accurate for FD.io VPP 19.04 release. The sections performance & operational data below correlate directly with those sections from the FD.io CSIT performance report.
Summary¶
Option |
Relative Performan ce |
Features & Notes |
|---|---|---|
Lowest |
Match on restricted L2-L4 fields, stateful & stateless |
|
Highest (software only) |
Match on Layer 3 IPs, stateless |
|
Highest (accelera ted) |
Match on restricted L2-L4 fields, stateless, limited number of flows |
|
TBD |
Match on any field in the first 80 bytes, Not measured |
FD.io VPP ACL Options¶
The FD.io VPP ACL Plugin¶
The plugin was originally developed as part of FD.io VPP and OpenStack integration. The plugin needs to be enabled on specific interfaces.
Supports stateful and stateless ACLs on …¶
MACs
IPS
UDP Ports
TCP Ports & Flags
ICMP Messages
Directional¶
Input ACLs
Run before the IP flow classification.
ACLs
Run before interface output.
Actions¶
Permit (sl)
Drop (sf)
Permit+Reflect (sf)
Stateful (sf)¶
Actions: permit+reflect
Most heavily optimized, as are the most common use case.
Faster because stateful uses a flow cache, it means the ACL hit is only taken once, up front for the flow and then becomes just look-up.
Uses more memory, less deterministic as the flow cache makes it more susceptible to the effects of the memory hierarchy and locality.
Stateless (sl)¶
Actions : permit, drop
Less optimized, less common use case.
Slower as there is no flow-cache, every new packet incurs the same amount ACL processing.
Uses less memory, and are more deterministic (compared to stateful).

FD.io VPP COP¶
IPv4/IPv6 white-lists using the FD.io VPP FIB, with support for multiple nested white-lists.
Design notes:¶
The cop graph nodes (input & white-list) make reuse of the FD.io VPP in FIB 2.0 implementation. Essentially a successful lookup in the FIB, indicates that a packet has been white-listed and may be forwarded.
cop-input: Determines if the frame is IPv4 or IPv6, and forwards to ipN-copwhitelist graph node.
ipN-copwhitelist: uses the ip4_fib_[mtrie,lookup] functions to confirm the packet’s ip matches a route in the white-list fib.
Match: if it matches, it is then either sent to the next whitelist or to the ip layer.
No Match: if it there is not match, it is sent to error-drop.
Operational Data¶
Note: the double-pass of the ip4-lookup and ip4-rewrite.

Configuration¶
Note: a new VRF 1 is created which holds the whitelist, which then applied to the interface 1.
$ sudo vppctl ip_add_del_route <IP_ADDRESS>/24 via <IP_ADDRESS> sw_if_index 2 resolve-attempts 10 count 1
$ sudo vppctl ip_table_add_del table 1
$ sudo vppctl ip_add_del_route <IP_ADDRESS>/24 vrf 1 resolve-attempts 10 count 1 local
$ sudo vppctl cop_whitelist_enable_disable sw_if_index 1 ip4 fib-id 1
$ sudo vppctl cop_interface_enable_disable sw_if_index 1
FD.io VPP Flow¶
FD.io VPP Flow adds the ability for FD.io VPP to support matching of flows and taking an associated action. This information is then used to program hardware accelerations such as those available on network cards, e.g. Intel® Ethernet Flow Director technology on the Intel® Ethernet Controller X710/XXV710/XL710.
Supports¶
Actions¶
Count: don’t now what this does, presume it count’s matches.
Mark: Associate a matched flow with arbitrary data such as vxlan tunnel, for a lookup in the redirect graph node.
Buffer Advance: Can be used advance to an encapsulated ethernet or ip header.
Redirect to node: When you see a packet from flow xyz, the next node in FD.io VPP is the indicated graph node.
Redirect to queue: When you see a packet from flow xyz, is to redirect to rx queue n.
Drop: When you see a packet from flow xyz, drop the packet (next node is error drop).
Design Notes¶
Currently the only place in FD.io VPP that this is used, is to accelerate VXLAN bypassing the Ethernet and IP Layers.
Flow uses DPDK rte_flow API under the hood for those network interfaces programmed through DPDK.
Redirect to node: worth remember that if you are bypassing a graph, you are bypassing all the checks in the graph node, e.e time-to-live, crcs and the like.
Operational Data¶
FD.io CSIT numbers for VXLan do not use FD.io Flow support.
Performance¶
FD.io CSIT numbers for VXLan do not use FD.io Flow support.
FD.io VPP Classifiers¶
The most flexible form of ACLs in FD.io VPP enable the user to match anywhere in the first 80 bytes of the packet header.
Configuration¶
Match an IPv6….
$ sudo vppctl classify table mask l3 ip6 dst buckets 64
$ sudo vppctl classify session hit-next 0 table-index 0 match l3 ip6 dst 2001:db8:1::2 opaque-index 42
$ sudo vppctl set interface l2 input classify intfc host-s0_s1 ip6-table 0


Enter Suriname through the Suriname river as both Paramaribo and Domburg (upstream) lie on this river.
Enter preferably during daylight, as it can be confusing during the night with the numerous lights.
In addition, there is a dangerous wreck at the entrance which was reported May 2016. See details here.
Fly the 'Q' flag, lower the sails and motor in with the tide.
If waiting for daylight and/or the tide, you can safely anchor at the river mouth, OUT of the shipping lane in 5m of water, and wait.
Whilst all formalities must be completed in the city of Paramaribo, a new government rule does not allow yachts to anchor near the town (unless special permission has been granted), so all visiting yachts must proceed directly up stream to Domburg and travel to Paramaribo from there (only 10nm away).
Approx. 8 miles in, call MAS (Maritime Authority Suriname) on VHF channel 12 or 16, to advise them of your arrival. If nothing heard just proceed to Domburg, past the bridge over the river (height 90 mtr).
Clearance is not required immediately. Once settled in at Domburg, the skipper and crew should attend to clearance formalities in Paramaribo, easily reached by a direct bus link from Domburg. See transport for details on buses between Domburg and Paramaribo.
The skipper and all crew must attend all offices for clearance.
Note: It is sensible to dress reasonably smartly as cruisers have been refused access to the Foreign Police office because they were wearing shorts. Being polite and always greeting an official or person before asking a question will serve you well.
Clearing In from Domburg
The day before you plan to head into Paramaribo to clear in, go to Domburg internet shop and make 3 copies of your crew list. Remember, all crew (with their passports) must complete clearance.
Minibuses into town run from 6am to 4pm and it is strongly advised to start early (around 7am). The bus ends up at the Heiligenweg bus stop. Whilst it is possible to take buses to the various offices (see cruiser's report ), it is much simpler to take a taxi from Heiligenweg bus stop to all the various offices you need to visit. Arrange a set price for two hours (cost approx. SDR 40/hour).
Arriving yachts must first check in with the Foreigners Police (Vreemdelingen Politie (VP)), located on Jaggernath Lachmon street # 167. Go around the right side of the building into the VP office, the officer who deals with the yacht arrivals is in a separate office on the left. Here you will get your first stamp on your crew lists and one will be kept by the official.
Next, to the Immigration Office on the corner of Lim A Po and Watermolenstreet to obtain a tourist pass. They will keep one of the stamped crew lists as well. Pay at the office directly for a tourist pass, no passport photos needed.
If however you require a visa, you will need to go and pay for this at the bank and bring the receipt back to the Immigration office before the visa will be issued.
Lastly, return to the VP who will stamp your passports, you keep the other crew list.
You will need to check in with the VP every thirty days of your stay. They will give you a free extension stamp with a maximum stay of 3 months permitted on a tourist visa.
Clearing Out
When leaving the country, just an exit stamp on your crew list is needed at the foreign Police (vreemdelingen polite).
Cruisers have reported; "They will ask you when you are leaving. It cannot be further away than "tomorrow" otherwise they will tell you to come back. In practice nobody checks to see that you have actually left".
Last updated May 2016.
All passports must be valid for at least 6 months from arrival.
There is no need for a visa in advance, a stamp on your crew list and passport, and a tourist pass is obtained on arrival which allows you a stay of three months.
The following nationalities can now purchase a tourist card (visa) on arrival which is valid for three months (see Fees below):
Belgium, Bolivia, Canada, Chile, France, Germany, Great Britain and Northern Ireland, Netherlands, Paraguay, Peru, Uruguay, USA, Venezuela.
Even though the visa is valid for 3 months, you still have to visit the "vreemdelingen politie" every month to get your visa stamped.
Nationalities not on the above list will require a visa. This can be obtained on arrival, however does require payment at the bank and the receipt brought back to the Foreign Affairs office before the visa will be issued.
Note: If in St Laurent, French Guiana before coming to Suriname, it's possible to get a Tourist Pass for Suriname there (at the Suriname office) which eliminates having to do it here. This makes things easier with just one stop at MAS, and one stop at the Military Police required.
Last updated March 2016.
Firearms must be declared.
Prohibited imports include: all fruits (except reasonable quantity for personal use imported from the Netherlands), vegetables, plants, roots, bulbs, coffee, cacao, rice, fish, meat and meat products. In practice, these restrictions may not be strictly applied to visiting yachts.
There is no mechanism for bringing in spare or replacement parts duty free.
Last updated November 2014.
Travellers arriving from any country at risk of yellow fever (eg Guyana, French Guiana, Brazil, Venezuela) are required to show evidence of a yellow fever vaccination.
Malaria prophylaxis is advisable. There is some risk of bilharzia in coastal districts.
Several Hospitals are good and well- equipped in Paramaribo. Several private clinics do exist as well.
Scans/MRI/echo's are all available.
Dentists and any other medical service is good in Suriname.
ZIKA VIRUS ALERT: (September 2016) There have been recent safety alerts from the US State Department, UK Foreign Office, and Center for Disease Control (CDC) regarding travel to parts of Central and South America, Africa, southern Asia, the Caribbean, and the South Pacific islands. Suriname is an area of interest. There is growing concern about the rapid spread of the ZIKA Virus and the impact of the virus on pregnant women and babies. ZIKA is transmitted by mosquitos in tropical and sub-tropical climates, and there is currently no cure or vaccine. This situation is evolving rapidly, so please refer to the CDC’s dedicated website if you are intending to cruise in one of the effected areas.
Updated February 2015.
The government recently (1/3/16) increased the tourist card price from $25 US to $100 US in an effort to gain much needed foreign currency, but there was such an immediate impact on the tourist industry that it has been revised to $35 US (as of 15/3/16).
Last updated March 2016.
Military installations must not be photographed.
Animals must be declared to Customs and have appropriate papers.
