Raw but Cooked: Kinilaw

Cooking is simply defined as the preparation of food, typically using heat. In a biochemical process called denaturing, high temperatures from various methods such as grilling, braising or steaming alter proteins in meat and seafood, making them firmer (as with egg whites) or breaking down tissue to make them more tender (as with tough cuts like shanks). But heat is not the only way of achieving this denaturation.

Call it ‘chemical cooking’: acids can do the same job and there are many kinds of acidic agents easily found in the kitchen pantry, like citric acid from lemon and lime juices; acetic acid in vinegars; and tartaric and malic acids in wine. All of these are commonly used in marinades and brines in conjunction with heat-based preparation, not only to add flavor to food, but also to reduce cooking time by jumpstarting the protein breakdown process. However, many cuisines have traditional recipes that skip the last part altogether=and rely solely on acids to make the dish palatable.

Perhaps the best known of these is ceviche, the South American dish of raw seafood marinated in citrus, with regional variations in fish or shellfish, types of citrus, and other ingredients such as chilies, onions and tomatoes. Although Peru is generally accepted as the place of origin for modern ceviche, other theories trace its ancient roots across the ocean to the Pacific Islands, where similar raw marinated foods are quite common. Known by various names, like poisson cru in French Polynesia and ota ika in Samoa, Tahiti and Tonga, they are also prepared with citrus juice, but with the addition of coconut milk.

Kinilaw: Vinegar-cooked Seafood

These recipes are the likely precursors to the Philippines’ own iteration called kinilaw [key-knee-lawuh]. Despite some assumptions that it is simply ceviche brought over by Spanish colonizers, there is archaeological evidence that pre-Hispanic Filipinos were eating kinilaw nearly 700 years before any European influence. And although it is essentially the same idea – preparing raw protein with an acid rather than heat - there is a marked difference in our dish from the South American and Polynesian versions: Instead of citrus juice, it utilizes vinegar.

The sharp taste of vinegar can be refreshing on the palate, especially when tempered with subtly sweet coconut cream and enlivened by ginger and chilies. The following recipe is courtesy of Ernesto ‘Nonoy’ Rodriguez, who offers just-caught seafood and locally raised meats at the Salcedo Saturday Market in Makati City. His recipe is typical of the Visayas region in central Philippines and uses as its main ingredient sinamak, a regional specialty of coconut vinegar, chilies, ginger and garlic. The seafood of choice is large white shrimp or tanguigue (Spanish mackerel). As is usually the case with oft-made dishes prepared by heart, Nonoy’s recipe was not exact with amounts and so may be adjusted according to taste.

Many have asked how to stop overtype

In Microsoft Word this is accomplished by pressing, often accidentally, the INS (Insert) key. This key is very close to the backspace key on a standard keyboard. The current status of the Overtype mode is indicated by the letters OVR on Word's Status Bar. Overtype mode is off.

Why can’t the world’s greatest minds solve the mystery of consciousness?

One spring morning in Tucson, Arizona, in 1994, an unknown philosopher named David Chalmers got up to give a talk on consciousness, by which he meant the feeling of being inside your head, looking out – or, to use the kind of language that might give a neuroscientist an aneurysm, of having a soul. Though he didn’t realise it at the time, the young Australian academic was about to ignite a war between philosophers and scientists, by drawing attention to a central mystery of human life – perhaps the central mystery of human life – and revealing how embarrassingly far they were from solving it.

The scholars gathered at the University of Arizona – for what would later go down as a landmark conference on the subject – knew they were doing something edgy: in many quarters, consciousness was still taboo, too weird and new agey to take seriously, and some of the scientists in the audience were risking their reputations by attending. Yet the first two talks that day, before Chalmers’s, hadn’t proved thrilling. “Quite honestly, they were totally unintelligible and boring – I had no idea what anyone was talking about,” recalled Stuart Hameroff, the Arizona professor responsible for the event. “As the organiser, I’m looking around, and people are falling asleep, or getting restless.” He grew worried. “But then the third talk, right before the coffee break – that was Dave.” With his long, straggly hair and fondness for all-body denim, the 27-year-old Chalmers looked like he’d got lost en route to a Metallica concert. “He comes on stage, hair down to his butt, he’s prancing around like Mick Jagger,” Hameroff said. “But then he speaks. And that’s when everyone wakes up.”

The brain, Chalmers began by pointing out, poses all sorts of problems to keep scientists busy. How do we learn, store memories, or perceive things? How do you know to jerk your hand away from scalding water, or hear your name spoken across the room at a noisy party? But these were all “easy problems”, in the scheme of things: given enough time and money, experts would figure them out. There was only one truly hard problem of consciousness, Chalmers said. It was a puzzle so bewildering that, in the months after his talk, people started dignifying it with capital letters – the Hard Problem of Consciousness – and it’s this: why on earth should all those complicated brain processes feel like anything from the inside? Why aren’t we just brilliant robots, capable of retaining information, of responding to noises and smells and hot saucepans, but dark inside, lacking an inner life? And how does the brain manage it? How could the 1.4kg lump of moist, pinkish-beige tissue inside your skull give rise to something as mysterious as the experience ofbeing that pinkish-beige lump, and the body to which it is attached?

Synchronous vs. Asynchronous

• Synchronous data transfer: sender and receiver use the same clock signal

  • supports high data transfer rate
  • needs clock signal between the sender and the receiver
  • requires master/slave configuration

• Asynchronous data transfer: sender provides a synchronization signal to the receiver before starting the transfer of each message

  • does not need clock signal between the sender and the receiver
  • slower data transfer rate

Notes:

There are many serial data transfer protocols. The protocols for serial data transfer can be grouped into two types: synchronous and asynchronous. For synchronous data transfer, both the sender and receiver access the data according to the same clock. Therefore, a special line for the clock signal is required. A master (or one of the senders) should provide the clock signal to all the receivers in the synchronous data transfer.

For asynchronous data transfer, there is no common clock signal between the sender and receivers. Therefore, the sender and the receiver first need to agree on a data transfer speed. This speed usually does not change after the data transfer starts. Both the sender and receiver set up their own internal circuits to make sure that the data accessing is follows that agreement. However, just like some watches run faster than others, computer clocks also differ in accuracy. Although the difference is very small, it can accumulate fast and eventually cause errors in data transfer. This problem is solved by adding synchronization bits at the front, middle or end of the data. Since the synchronization is done periodically, the receiver can correct the clock accumulation error. The synchronization information may be added to every byte of data or to every frame of data. Sending these extra synchronization bits may account for up to 50% data transfer overhead and hence slows down the actual data transfer rate.

5 Natural Air-Conditioning Designs Inspired by Nature

*It's all anew and I will endeavor to share only my own personal pictures that I have taken from around the world.

 At times the most advanced technologies are the ones that we have tossed aside for the favor of gadgets.

With heat waves gripping much of the planet, electricity grid operators are sweating even more than their customers. Air-conditioning uses a tremendous amount of energy, but a new group of designers think they can solve that problem by mimicking Mother Nature's craftiness.

Janine Benyus, a biologist, innovation consultant, and author of the book Biomimicry: Innovation Inspired by Nature, told National Geographic that copying the way plants and animals solve natural problems can provide many benefits, from environmental sustainability to economic efficiency. (See "Nature Yields New Ideas for Energy and Efficiency.")

"With biomimicry we're able to apply fresh thinking to traditional manufacturing, to undo the toxic and energy-intensive mistakes of the past," said Benyus, who is part of a group that hopes to lead a new revolution in design by imitating nature. "I wish we had been at the design table at the Industrial Revolution."

In natural systems, nothing is wasted, since everything can be used by something else. Instead of using large inputs of energy and toxic chemicals to make things and ship them across the globe, nature makes what it needs where it needs it, with water-based chemistry.

These designs suggest some of what could be learned by applying the lessons of biomimicry to the problem of air-conditioning in particular. (See "In Search of Green Air-Conditioning.")

1.    Ventilation Inspired by Termites

Perhaps the most famous example of biomimicry when it comes to heating and cooling is ventilation inspired by termites. A few years ago, scientists observed that big termite mounds in Africa stay remarkably cool inside, even in blistering heat. The insects accomplish that feat with a clever system of air pockets, which drive natural ventilation through convection.

Architect Mick Pearce and engineering firm Arup borrowed that idea to build Eastgate Centre, a large office and shopping center in Zimbabwe that is cooled with the outside air. The system uses only 10 percent as much energy as conventional air-conditioning to drive fans that keep the air circulating.

2.    Countercurrent Heat Exchange Inspired by Birds

Ducks and penguins that live in cold climates have an innovative adaptation that helps them survive the elements. The veins and arteries in their feet have a countercurrent configuration, which ends up warming the blood that is closer to the animal's core and cooling the blood at the edges of its extremities. By keeping cooler blood closer to the snow and ice, such birds lose less body heat overall.

Shell tube heat exchangers in industrial-scale heating and cooling systems use a similar type of flow pattern to maximize efficiency, as Clayton Grow, author of  The Writing Engineer blog, has pointed out.

3.    Moisture Absorption Inspired by Ticks

Grow notes that a system called a liquid desiccant dehumidifier also seems to follow a form of biomimicry. Such a system is designed to pull humidity from the air inside a building (traditional air-conditioning also reduces humidity). It uses a liquid salt solution—something similar to what the brown dog tick secretes to absorb water from the air.

(See "Seeking to Cool Air-Conditioning Costs.")

4.     Efficient Fans Inspired by Tornadoes and Whirlpools

A company called PAX Scientific (slogan: Capturing the Force of Nature) is marketing a fan based on the logarithmic spiral shape found in such phenomena as tornadoes, whirlpools, and even airflow in the human trachea. The company says the fans have lower turbulence and higher efficiency for cooling.

(Quiz: What You Don't Know About Air-Conditioning)

5.     Efficient Fans Inspired by Whale Flippers

In another take on better fan design, a startup called WhalePower is developing fan blades that produce greater lift, and therefore move more air, thanks to the bumpy design of a humpback whale's flipper.

WhalePower says its fans move 25 percent more air than conventional fans while using 20 percent less energy. The company is also working on more powerful wind turbine blades.

Network management with LXD (2.3+)

*Back to the grind

Introduction

When LXD 2.0 shipped with Ubuntu 16.04, LXD networking was pretty simple. You could either use that “lxdbr0” bridge that “lxd init” would have you configure, provide your own or just use an existing physical interface for your containers.

While this certainly worked, it was a bit confusing because most of that bridge configuration happened outside of LXD in the Ubuntu packaging. Those scripts could only support a single bridge and none of this was exposed over the API, making remote configuration a bit of a pain.

That was all until LXD 2.3 when LXD finally grew its own network management API and command line tools to match. This post is an attempt at an overview of those new capabilities.

Basic networking

Right out of the box, LXD 2.3 comes with no network defined at all. “lxd init” will offer to set one up for you and attach it to all new containers by default, but let’s do it by hand to see what’s going on under the hood.

To create a new network with a random IPv4 and IPv6 subnet and NAT enabled, just run:

stgraber@castiana:~$ lxc network create testbr0
Network testbr0 created

You can then look at its config with:

stgraber@castiana:~$ lxc network show testbr0
name: testbr0
config:
 ipv4.address: 10.150.19.1/24
 ipv4.nat: "true"
 ipv6.address: fd42:474b:622d:259d::1/64
 ipv6.nat: "true"
managed: true
type: bridge
usedby: []

If you don’t want those auto-configured subnets, you can go with:

stgraber@castiana:~$ lxc network create testbr0 ipv6.address=none ipv4.address=10.0.3.1/24 ipv4.nat=true
Network testbr0 created

Which will result in:

stgraber@castiana:~$ lxc network show testbr0
name: testbr0
config:
 ipv4.address: 10.0.3.1/24
 ipv4.nat: "true"
 ipv6.address: none
managed: true
type: bridge
usedby: []

Having a network created and running won’t do you much good if your containers aren’t using it.
To have your newly created network attached to all containers, you can simply do:

stgraber@castiana:~$ lxc network attach-profile testbr0 default eth0

To attach a network to a single existing container, you can do:

stgraber@castiana:~$ lxc network attach my-container default eth0

Now, lets say you have openvswitch installed on that machine and want to convert that bridge to an OVS bridge, just change the driver property:

stgraber@castiana:~$ lxc network set testbr0 bridge.driver openvswitch

If you want to do a bunch of changes all at once, “lxc network edit” will let you edit the network configuration interactively in your text editor.

Static leases and port security

One of the nice thing with having LXD manage the DHCP server for you is that it makes managing DHCP leases much simpler. All you need is a container-specific nic device and the right property set.

root@yak:~# lxc init ubuntu:16.04 c1
Creating c1
root@yak:~# lxc network attach testbr0 c1 eth0
root@yak:~# lxc config device set c1 eth0 ipv4.address 10.0.3.123
root@yak:~# lxc start c1
root@yak:~# lxc list c1
+------+---------+-------------------+------+------------+-----------+
| NAME |  STATE  |        IPV4       | IPV6 |    TYPE    | SNAPSHOTS |
+------+---------+-------------------+------+------------+-----------+
|  c1  | RUNNING | 10.0.3.123 (eth0) |      | PERSISTENT | 0         |
+------+---------+-------------------+------+------------+-----------+

And same goes for IPv6 but with the “ipv6.address” property instead.

Similarly, if you want to prevent your container from ever changing its MAC address or forwarding traffic for any other MAC address (such as nesting), you can enable port security with:

root@yak:~# lxc config device set c1 eth0 security.mac_filtering true

DNS

LXD runs a DNS server on the bridge. On top of letting you set the DNS domain for the bridge (“dns.domain” network property), it also supports 3 different operating modes (“dns.mode”):

• “managed” will have one DNS record per container, matching its name and known IP addresses. The container cannot alter this record through DHCP.
• “dynamic” allows the containers to self-register in the DNS through DHCP. So whatever hostname the container sends during the DHCP negotiation ends up in DNS.
• “none” is for a simple recursive DNS server without any kind of local DNS records.

The default mode is “managed” and is typically the safest and most convenient as it provides DNS records for containers but doesn’t let them spoof each other’s records by sending fake hostnames over DHCP.

Using tunnels

On top of all that, LXD also supports connecting to other hosts using GRE or VXLAN tunnels.

A LXD network can have any number of tunnels attached to it, making it easy to create networks spanning multiple hosts. This is mostly useful for development, test and demo uses, with production environment usually preferring VLANs for that kind of segmentation.

So say, you want a basic “testbr0” network running with IPv4 and IPv6 on host “edfu” and want to spawn containers using it on host “djanet”. The easiest way to do that is by using a multicast VXLAN tunnel. This type of tunnels only works when both hosts are on the same physical segment.

root@edfu:~# lxc network create testbr0 tunnel.lan.protocol=vxlan
Network testbr0 created
root@edfu:~# lxc network attach-profile testbr0 default eth0

This defines a “testbr0” bridge on host “edfu” and sets up a multicast VXLAN tunnel on it for other hosts to join it. In this setup, “edfu” will be the one acting as a router for that network, providing DHCP, DNS, … the other hosts will just be forwarding traffic over the tunnel.

root@djanet:~# lxc network create testbr0 ipv4.address=none ipv6.address=none tunnel.lan.protocol=vxlan
Network testbr0 created
root@djanet:~# lxc network attach-profile testbr0 default eth0

Now you can start containers on either host and see them getting IP from the same address pool and communicate directly with each other through the tunnel.

As mentioned earlier, this uses multicast, which usually won’t do you much good when crossing routers. For those cases, you can use VXLAN in unicast mode or a good old GRE tunnel.

To join another host using GRE, first configure the main host with:

root@edfu:~# lxc network set testbr0 tunnel.nuturo.protocol gre
root@edfu:~# lxc network set testbr0 tunnel.nuturo.local 172.17.16.2
root@edfu:~# lxc network set testbr0 tunnel.nuturo.remote 172.17.16.9

And then the “client” host with:

root@nuturo:~# lxc network create testbr0 ipv4.address=none ipv6.address=none tunnel.edfu.protocol=gre tunnel.edfu.local=172.17.16.9 tunnel.edfu.remote=172.17.16.2
Network testbr0 created
root@nuturo:~# lxc network attach-profile testbr0 default eth0

If you’d rather use vxlan, just do:

root@edfu:~# lxc network set testbr0 tunnel.edfu.id 10
root@edfu:~# lxc network set testbr0 tunnel.edfu.protocol vxlan

And:

root@nuturo:~# lxc network set testbr0 tunnel.edfu.id 10
root@nuturo:~# lxc network set testbr0 tunnel.edfu.protocol vxlan

The tunnel id is required here to avoid conflicting with the already configured multicast vxlan tunnel.

And that’s how you make cross-host networking easily with recent LXD!

Conclusion

LXD now makes it very easy to define anything from a simple single-host network to a very complex cross-host network for thousands of containers. It also makes it very simple to define a new network just for a few containers or add a second device to a container, connecting it to a separate private network.

While this post goes through most of the different features we support, there are quite a few more knobs that can be used to fine tune the LXD network experience.
