This was a project to take the concept of a "challenge coin" - popular in military culture as tokens of achievements - and have some manufactured to hand out at an information security conference. Many of the Huntr InfoSec team are or were at one time members of the armed forces and would be evangelists for our threat detection platforms at the trade shows.
The design began digitally with a graphic meant to incorporate the three tenants of "guided hunting" (monitoring your network and isolating threats):
PERCEPTION - Huntr allows users to gain insight into their network through a wide array of simple and intuitive tools. Perception can come from many sources; file introspection, triaging raw network logs, or combing through endpoint activity. Huntr provides a platform in which analysts can move freely from one data source to the next, and constantly improve their perceptions of all areas of their network.
KNOWLEDGE - Huntr equips an analyst with the tools necessary to continuously build understanding of adversaries or malicious intent from their perceptions. The culmination of knowledge in an environment is paramount to efficient and effective hunting operations.
ACTION - Once knowledge has been accrued, action can take place. Huntr provides mechanisms for live detections of network data, file triggering via signatures, or offloading a payload to the users endpoint of choice.
The pyramid's three sides represent the three tenants while the eye with the crosshair represents guided hunting as a whole. Once a digital design was approved it was taken to a manufacturer to press and enamel the finished product.

We wanted something to give out at events or leave with clients that would be useful and fun enough that they'd be more likely to keep it around and show off to others. With VR just beginning to get popular we setup a portion of our booths to showcase some nicer Samsung VR headsets to show eventgoers what VR was all about. When they were done we'd encourage them to download a free app on the Apple or Android app store and take one of our free Google Cardboard compatible headsets. This quickly became a handout that people would ask about at later events so proved to be memorable and make a lasting impression.
The design itself was taken from the ad campaigns we had been running in trade media at the time to match our other branding. We had a company DodoCase send us design templates for their "P2" model and got to work. When we ordered about 100 headsets the cost ended at about $15 each, but since most of our trade shows were for brand-to-brand marketing it worked out that our select audience was worth it (including keeping some for ourselves and making sure our favorite clients got a few, too).
When Innov8tive got new fleet vehicles it was decided they'd like to have them wrapped to get noticed while driving around. A concept was created based upon our ad campaigns from that time. Another "light" concept was created that would be used mostly as the "daily driver" where the windows would be clear of any perforated art for maximum visibility and where being loud and obvious wasn't a priority.
Once completed the main Chevy Spark turned out great:
It was also used in promotions across social media where if you snapped a photo of the car "in the wild" (such as parked at a local business) and tagged Innov8tive in the post the user would be entered into a monthly giveaway:
Another vehicle wrap was also commissioned for another company, Interior Gilt, for use on their GMC Yukon which was used for deliveries and promotional meets.
A concept for neon to go along the face of our building with the lightbulb logo arranged at angles in two pieces to be better viewed from the street when driving by.
A clear plexiglass panel with a thin layer of brushed metal over the face with the Innov8tive logo cut out and a thin layer of blue, semi-opaque PVC at the back to show through the clear plexi material, it was then installed elevated above the brick face with room beneath to be backlit via LEDs.
An interior design client for Interior Gilt saw a t-shirt that had a map of a city (Dublin, Ireland I believe) that had all streets, rivers, and geography etched into a gold foil square. Being located in Stillwater, OK they wanted something similar but in poster form to hang above a table in their entryway. Their style was colorful and eclectic, so wanted something more like watercolor or paint splatters.
After visiting several geological and municipal websites for Stillwater I downloaded numerous PDF maps and worked to layer them on top of each other to act as cutouts. Streets were given a heavier stroke than elevation changes, and bodies of water were filled in. Once the layers were created a paint background was placed behind them. Due to the large numbers of shapes involved the file came out huge even when flattened and optimized. However, it printed wonderfully and the interior design project was a success.
S. Powell & Co., an upscale clothing boutique in Uptown OKC, wanted something loud and bold to spice up their typical mannequin displays in the front windows of the shop. There were six, four female and two male, and their idea was to hang celebrity photos so that they would take the place of where each mannequin's face would be. As the entire store's motif was based around a large, pink neon sign, and their entire storefront was vivid, the more striking each poster the better.
Finding useful photos of icons that are poster sized is tricky, but taking good (but small) pics and tracing them in Illustrator allowed them to be scaled up as vectors rather than worrying about pixellation and distortion when blown up to 18x24. Paint brush outlines, Warhol-style backgrounds, and cell shading color overlays brought it all together.
We went through several different color changes for each part though, starting tame and pastel at first and then getting more intense and bold as discussions evolved. their marketing coordinator kept saying "more, louder, make those colors POP" until the final product was sure to catch a pedestrian's attention and get them to check out the displays.
The store also ran flyers to different parts of town and social media campaigns each emphasizing a different celebrity as a discount code. If someone mentioned Whitney for example then they knew they heard about the event via social media whereas others might have been a flyer from a restaurant, gym, bar or dance studio. Having different calls to action allowed for easy tracking to determine how popular each opportunity was for them.
Innov8tive wanted to rebrand their website and focus on developing apps and software that could interact with the "Internet of Things", augmented reality, and real world applications of use.
During a marketing meeting I drew a sketch from the chief product officer's talking points. He pictured rolling hills "like Microsoft's old wallpaper" and wanted the horizon to include references to both oil and gas industries and solar panel and wind turbine fields to show the progression of technology (plus Oklahoma has numerous large energy companies we wished to target). A satellite would be included to connect services to the world below. He also wanted the foreground to highlight an app we were developing called DirectDots which would use beacon technology to guide visitors through buildings to their destinations (discussed on my UI/UX page). The sketch came out cohesive enough that we decided to move forward with a digital infographic to use as the header of the website.
The digital version was created in Adobe Illustrator with isolated layers so that a parallax effect could be applied at different intervals to each layer creating a three dimensional effect while a viewer scrolls down. A still render of it is available below.
You can view the final parallaxed version live at the top of Innov8tive's website.
One of my career highlights while working for a la mode and Pipeline ROI (its real estate web site division) was teaching daily live webinars to our users. The topics would sometimes change whether covering how-to on our proprietary content management platform or how to utilize email marketing or social media to garner results. The most popular topic though was search engine optimization. Below is a recording of one of those webinars from August of 2015.


Sony is making first-party games for PlayStation 5 that will 'make or break' console
In a new interview, Jim Ryan, CEO at Sony, has finally revealed new details about the PlayStation 5 ahead of its release in Holiday 2020
by Shivali Best, https://www.facebook.com/shivalibestjournalist/With over a year to go before the PlayStation 5 is finally unveiled, Sony has remained fairly tight-lipped about the highly-anticipated console.
Sony has already confirmed the console’s name - PlayStation 5 - and a vague launch date of ‘Holiday 2020’, but hasn’t told us much more about the device.
Now, Jim Ryan, CEO at Sony, has finally revealed new details, during a new interview with GamesIndustry.biz.
He said: “As we move towards the next-generation in 2020, one of our [Sony's] tasks - probably our main task - is to take that community and transition it from PlayStation 4 to PlayStation 5, and at a scale and pace that we've never delivered on before.”
Mr Ryan said that Sony is working on several first-party games that could ‘make or break’ the success of the PlayStation.
However, he added that Sony is already ‘hearing from developers and publishers [about] the ease in which they are able to get code running on PlayStation 5’, which is reportedly ‘way beyond any experience they've had on any other PlayStation platform.’
The added details come shortly after Sony finally confirmed the name and launch date for its next generation console.
As expected, the console is called the PlayStation 5 , and will launch in time for ‘Holiday 2020.’
In a blog about the news, Jim Ryan , President and CEO of SIE, said: “Since we originally unveiled our next-generation console in April, we know that there’s been a lot of excitement and interest in hearing more about what the future of games will bring.
“Today I’m proud to share that our next-generation console will be called PlayStation 5, and we’ll be launching in time for Holiday 2020.”

Packet decoding framework. Packet buffers are scanned and decoded.
loop
and
dispatch
methods that deliver decoded packets to the registered handler. The
class JPacket allows the programmer to check for existance of certain
protocol headers within the packet's data buffer. The programmer can use
a header to then access any of the fields and logic for that protocol.
Here is an example of what a JPacketHandler might look like:
JPacketHandlerThe example demonstates ahandler = new JPacketHandler () { private Ethernet eth = new Ethernet(); private Ip4 ip = new Ip4(); public void nextPacket(JPacket packet, String user) { if (packet.hasHeader(Ethernet.ID)) { eth = packet.getHeader(eth); byte[] dstMac = eth.destination(); byte[] srcMac = eth.source(); int type = eth.type(); // Do something } /* * For convenience there is a hasHeader method that takes a header instance * and combines hasHeader with getHeader methods if the header exists. */ if (packet.hasHeader(ip)) { int flags = ip.flags(); int offset = ip.offset(); byte[] srcIp = ip.source(); byte[] dstIp = ip.destination(); int protocol = ip.protocol(); } // Or can simply print out the contents of the packet System.out.println(packet.toString()); } }
JPacketHandler
implementation, which gets passed into
loop/dispatch
methods and receives packets. The handler's
nextPacket
method receives a fully decoded packet. The information about which
headers exist, where in the buffer and how long they are is recorded in
native structures which
JPacket, JPacket.State, JHeader, JHeader.State
classes access. The method
JPacket.hasHeader
is a simply bitwise operation on an unsigned integer that is very
efficient and fast.
The typical steps for working with the packet objects is first to check if the header the user is insterested in exists in the packet, has been found by the packet scanner, and then request that user supplied header instance is peered with the native structures that describe that header.(Peering means that the physical address of the native structure is recorded somewhere in the java class beeing peered and afterwards that class uses that pointer to access and retrieve data from the physical native structure or buffer.)
The framework provides additional Pcap.loop and
Pcap.dispatch
methods which allow the user to supply a JPacketHandler
,
as opposed to PcapHandler
, which delivers a decoded JPacket
object to the user's callback method JPacketHandler.nextPacket(JPacket
packet, Object user)
JPacket
class is the main interface to the decoded
packet information, specifically; which protocol headers exist in the
packet, found by scanning the raw byte buffer, and detailed information
on those headers. The user can query a JPacket
using
methods JPacket.hasHeader(int id)
, JPacket.getHeader(T
header):<T extends JHeader> T
and JPacket.getCaptureHeader()
which returns the capture information such as timestamp and wirele
(length of the packet as seen on the network wire.)
There are also numerous support and other implementation classes such as
The scanner implementation is almost completely in native code. The scanner when its initialized allocates a large native memory block to hold its state and state about every packet it decodes. A pointer into the buffer is maintained which points to memory space where packet state can be recorded. Pointer is advanced for each packet that is being scanned. When the buffer is exhausted and the end is reached, the buffer simply wraps around to the beginning and the buffer is reused. This is the same algorithm that native libpcap uses for its capture buffer. So both the raw packet buffer, maintained by libpcap, and the packet decoded state information, maintained by JScanner, are kept in temporary, roundrobin buffers. This is something that also applies to other Pcap.loop and Pcap.dispatch methods that only dispatch raw byte buffers.
As packets arrive and the scanner is asked to scan them, it increments a pointer to a packet_state_t structure, within its buffer. The packet_state_t structure is where information is recorded about each headers. First there is a compress bitmap which using header's numerical IDs, records information about the presence of a header by setting a bit in this bitmap (an unsigned integer). Calls to JPacket.hasHeader(int id) simply check if a bit is set for a specific header ID and return true or false. Therefore JPacket.hasHeader checks are very light and fast and can be made frequently without having to worry about performance. Secondly, the scanner also records header's position within the buffer and the header's length. That information is also recorded in packet_state_t which has a header_state_t array member. The last header is typically a payload header, a special header that is catch all and captures the remainder of the packet that was not matched with any protocol header.
Before we begin on native structures, lets look at the class inheritance tree.
jMemory +-> JBuffer | +-> JPacket - peered with libpcap packet data buffer | +-> JStruct +-> JPacket.State - peered with JScanners packet_state_t structure +-> JHeader.State - peered with JScanners header_state_t structureFurther more, JPacket maintains an internal reference to a JPacket.State object as a private field. That is JPacket is peered with libpcap packet buffer, while a separate JPacket.State object is peered with the JScanner packet state structure. Notice that JPacket extends JBuffer, therefore any JPacket can be used as a normal JBuffer providing full access to all of the packets raw contents. The state information is allocated and maintained by JScanner.
Packets are assigned a packet_state_t structure by peering a java class with this native memory structure. jNetPcap uses the concept of native peers by holding the physical memory address as a internal private field within the java object. Native functions when called upon, retrieve this address location, cast a local pointer to that physical memory location for the structure that the class is peered with and then access that information. So a JPacket.State object is peered with a packet_state_t structure (residing in native memory) by simply changing a single java field. Java objects that are peered, hold very little additional information about the structure. There are some additional fields that are maintained for security purposes such as the size of the memory block and who the java owner of that memory block is. This information is only maintained for security and deallocation of memory purposes when the java parent object is garbage collected. This peering mechanism allows previously allocated packets to be reused extrememly efficiently, by simply changing a single pointer to a packet_state_t structure within it and changing the state of the packet immediately. JHeaders also maintain their state in this way.

SEPPAN A film review by Peter Reiher Copyright 1988 Peter Reiher
The following review is of a film appearing at the recent AFI Film Festival in Los Angeles. I have no way of knowing whether the film reviewed will appear at any normal theaters any time in the near future (or even at all).
Sometimes it seems like every Scandinavian film made since Ingmar Bergman retired is about children. In the Eighties, I've probably seen a couple of dozen new films from Sweden, Norway, Denmark, and Finland, and almost half of those have been primarily about children. In that time I've seen four Danish films, four Swedish films, a Norwegian film, and a Finnish film that took children as their main subject. (Plus an Icelandic one, which I guess should count, as well.) What could cause this seeming obsession? Do the Scandinavians really just make films about kids? Or are their films about children the only ones good enough to bother showing abroad? Or do US distributors feel their market will be more amenable to Nordic tots than sub-Arctic angst? Well, most of them are quite good, so I guess I shouldn't complain, but the phenomenon is still odd.
What brought this imbalance in subject matter to my attention was the first film I saw at the current AFI Film Festival. SEPPAN is yet another Swedish film about kids. Because it's set in the 1950s, and because the AFI Festival is not above just about any misrepresentation that will get people to come see their films, the program billed it as similar to MY LIFE AS A DOG. In actuality, other than the period, and a coincidental bit about Soviet satellites, there's no resemblance, either in subject matter or quality.
SEPPAN is about a group of children whose parents were World War II refugees who fled to Sweden. Temporarily settled in Seppan, a suburb of Stockholm, children from Finland, Russia, and Austria intermingle, in the process of becoming Swedish. The film traces about one year in the life of some of these children, focusing primarily on two girls on the verge of adolescence.
Perhaps "focusing" is a poor choice of words, though, because the film's major problem is focus. SEPPAN doesn't seem to have much of a point. Director/writer Agneta Fagerstrom-Olsson does not choose any central linchpin for her story. There are a few tragedies, some growing up, an unenthusiastic examination of the relationships of parents and children, a dalliance with a look at childhood friendship, and, finally, some episodes dealing with the cruelty of children. The whole seems more like a reminiscence without a point than a story. SEPPAN is moderately interesting in its parts, but never comes together into a whole.
Fagerstrom-Olsson deserves praise for some aspects of the film, however. The acting of the children is marvelously natural. The script has the feel of truth, though, alas, also the feel of irrelevancy. The photography (by John O. Olsson) is interesting and pretty in a gloomy, overcast way. Fagerstrom- Olsson definitely has the courage of her convictions, in her willingness to show children as they really are, rather than as we'd like them to be. But, in her attempts to avoid crowd-pleasing sellouts, she has failed to substitute anything to interest the audience, at all.
SEPPAN is not too likely to get much play outside of Scandinavia, except, perhaps, at film festivals. If it does, it certainly won't match the success of MY LIFE AS A DOG. The experience of watching SEPPAN is like hearing someone talk extemporaneously about their childhood. Unless one shares the experiences, or unless the experiences are extraordinary, or unless the teller is a master, childhood reminiscences are usually less than fascinating. SEPPAN fails on the latter two counts, so its potential interest for a viewer must be based on their childhood's relationship to Swedish post-WWII refugee camps.

aweek-package.Rd
The aweek package is a lightweight solution for converting dates to weeks that can start on any weekday. It implements the aweek class, which can easily be converted to date and weeks that start on different days.
When you work with aweek, you will want to make sure that you set the default
week_start
variable to indicate which day of the week your weeks should
begin. This can be done with set_week_start()
. It will ensure that all of
your weeks will begin on the same day.
get_week_start()
returns the global week_start option
set_week_start()
sets the global week_start option
date2week()
converts dates, datetimes, and characters that look like dates to weeks
as.aweek()
is a wrapper around date2week()
that converts dates and datetimes
start
argument.
get_aweek()
converts week numbers (with years and days) to aweek objects.
get_date()
converts week numbers (with years and days) to Dates.
as.aweek()
converts ISO-week formatted strings to aweek objects.
week2date()
converts ISO-week formatted strings to Date.
as.POSIXlt() converts to POSIXlt.
as.character()
trunc()
removes the weekday element of the ISO week string.
factor_aweek()
does the same thing as trunc(), but will create a factor
with levels spanning all the weeks from the first week to the last week.
Useful for creating tables with zero counts for unobserved weeks.
change_week_start()
will change the week_start attribute and adjust the
weeks accordingly so that the dates will always be consistent.
When you combine aweek objects, they must have the same week_start attribute. Characters can be added to aweek objects as long as they are in ISO week format and you can safely assume that they start on the same weekday. Dates are trivial to add to aweek objects. See the aweek documentation for details.

Hi there
Love the project and the community.
Is their an opportunity for an Australian Plug (AU) on the new emonPi Solars PV?
Also I'm just wondering, will I need a seperate emonTx if I want to understand the usage across different switches? All up I would like to understand how much I'm importing into the grid, how much I'm creating, how much I'm exporting (which I assume will be creating minus usage) and also the individual usage of my ducted aircon and solar hot water pump. Or can the emonPi Solar PV do it all?
Thanks!
Re: emonPi and AU Plug
I don't think you can do all that on your emonPi. You have a single phase, 230 V supply? The emonPi can measure two currents, implying two separate powers. So Nett Grid power is one, PV infeed is the second. For any more (up to 4) you need to add an emonTx and ac adapter, which would give you two spares on the emonTx (or on the Pi, or 1 on each - depends on where you locate everything in relation to the cable installation in your premises).
Conventionally, we call Import positive, so Import is the positive only part of Nett Grid power transfer, export is the negative only part.
Re: emonPi and AU Plug
I'm across the ditch in NZ and I run an EMONTX V3 and a EMONBASE running the EMONCMS monitoring software, the EMONTX has a UK Power supply on a socket converter and I measure:
Grid Import / Export on Channel 1
Solar Output on Channel 2
Solar Hot Water power diversion on Channel 3
SPA Heater power diversion on Channel 4
In my case the Solar goes into the house via a basement subboard and the grid enters via an in wall meter cabinet. I have a Current Transformer around each cable to provide the readings.
Re: emonPi and AU Plug
This is perfect, thank you so much guys.
I'm guessing from a voltage point of view, I will just need to buy the UK Plug which I assume preships at 240V. I'll read the manual, but I assume I don't need to do anything to ensure it operates at 230V?
Can an EMONTX V3 connect to a EMONPI SOLAR PV (for net Nett grid and PV infeed (Thanks Robert)? This would be an ideal setup for me as the EMONPI Solar PV for total net usage then expand when I have saved some more money to the EMONTX for monitoring of individual circuits).
Re: emonPi and AU Plug
The ac adapter is fine at 230 V for the Pi, and for the emonTx provided you don't have too many temperature sensors. That's because the current available is limited to prevent the current pulse drawn by the half-wave rectifier from causing too big a dip in the waveform that is also being used also for the voltage measurement.
You can connect (by radio) any sensible number of emonTx's, the limit comes from multiple transmitters sharing the same frequency.

Luis Enrique returns as Spain coach after daughter’s death
by TALES AZZONIMADRID (AP) — Luis Enrique is returning as Spain coach five months after stepping down because of his daughter’s illness.
He is taking over from former assistant Robert Moreno, who coached the team through qualifying for the 2020 European Championship. His last match was on Monday, a 5-0 rout of Romania in Madrid.
Luis Enrique’s 9-year-old daughter, Xana, died of a type of bone cancer less than three months ago.
Moreno had said a few months ago he would leave the job if Luis Enrique decided to return. He said he “would be delighted to step aside” if the former coach was ready to come back.
Federation president Luis Rubiales said it was always clear that Luis Enrique would return as coach when felt he was ready.
“Luis Enrique was always the leader of this project,” Rubiales said. “Moreno would remain as the national team coach if Luis Enrique didn’t want to return.”

Moreno will no longer work as an assistant coach to Luis Enrique.
Luis Enrique resigned from the national team in June, a few months after Xana was diagnosed. He had tried to remain in charge while staying with his family, making decisions and watching practices while being away.
Spain ended its qualifying campaign as the Group F winner with eight wins and two draws. “La Roja” finished five points in front of second-place Sweden. It will be one of the top seeded teams for next month’s Euro 2020 draw.
Spanish media said Moreno said goodbye to players after the match against Romania at the Wanda Metropolitano Stadium. He did not show up to speak to the media in the post-match news conference.

Lights are dimming down, small chair creaks are getting ever louder in a quieter classroom, the small light illuminating through an ajar door is sent back to the void when the small wooden doorstop is kicked away. Intensifying orchestral music is starting to play with the intro credits of Man With A Movie Camera by Dziga Vertov. After finishing the film, everyone knew they felt something and had ideas regarding it. One thing is for sure, it hasn’t left anyone indifferent.
The film Man with a Movie Camera represents
AN EXPERIMENTATION IN THE CINEMATIC COMMUNICATION
WITHOUT THE USE OF INTERTITLES
WITHOUT THE HELP OF A SCENARIO
WITHOUT THE HELP OF THEATRE
Man With A Movie Camera is almost a silent movie with incredibly fast-paced editing and the unique decision regarding its actors and plot, there is none. Let us traverse through different dimensions of what Dziga Vertov, originally David Abelevich Kaufman wanted us to experience through his work, and decide whether the experimental film stands the test of time with its ideas.
It is almost a silent film because if there is no audible dialogue, we are still greeted by an accompanying soundtrack that shifts and changes depending on current scenes. Interestingly enough, silent film directors usually would write the score, which will be played with every screening. However, Vertov only gave directions for the soundtrack, resulting in the movie accumulating over twenty different accompanying scores, each contributing slightly differently.
I watched the film with the musical accompaniment performed by The Alloy Orchestra did a terrific job of keeping the tension up throughout the whole screening. The instruments, pitch, and speed would all change depending on the environment that camera is in or what the camera is currently looking at. Parts with us following a fire truck hauling across town are aided by sirens playing in the background with beating drums, which seem to never get tired.
The second important feature of the film to notice is the apparent lack of a traditional narrative script, possibly a complete absence of it. Rarely this is done, as what we end up with is a movie with no central characters that develop or follow some overarching story that we are supposed to follow and care about. In a similar logical way, one would even dare to claim that Man With A Movie Camera is devoid of any meaning, primarily because it doesn’t have a plot for us to consciously follow. I would disagree.
 The absence of a traditional cast allows the movie to follow everyday people in their routine lives. From early morning until late night Soviet citizens are shown at work and play, actively being involved with the bustling urban lifestyle. It is different from a classical narrative structure, as we end up with more of a symphony-like development, where each scene is a whole story of its own.
This closes in tightly with what I believe to be one of the most important and defining features of Man With A Movie Camera and that is its use of a hidden camera, which allows us to witness the actuality of a modern life, where modern is defined by the standard of the 1920s. Silent movies of a similar era produced by the likes of Sergei Eisenstein and Lev Kuleshov are meticulously choreographed, where both attempt to force strong emotions with a propaganda-like purpose of affecting the masses in a very specific way.
I personally dislike propaganda or works of art that aims at making me or one of the audience members think and feel in a given way, which would be beneficial to them. Dziga Vertov takes a very interesting approach, as there is no grande moralizing or lecturing tone in his film. It is simply a collection of real-world footage with real regular people in it. This merely serves as a manifestation of his own views on cinema, which is fully cinematic. Vertov accomplishes at making it real, a literal unplayed film.
This cinematic nature of it with an incredible editing and montage job done by Elizaveta Svilova allows us to formulate our own understanding of the film. This ambiguity in its meaning, for many a complete lack thereof, gives us the freedom and liberty in creating our meaning and attributing it to the movie. With the range of activities and work shown through the work’s fast cutting, everyone can find a role that they could relate to in one way or another. I even had a physical sensation when watching people at the beach washing medical mud off their skins. When I was a child, my family went on a trip, which I hold very dear to me, where we tried the "mud cleaning" technique.
A good question that was raised after the screening was - "Is this propaganda?  As I mentioned, I don’t see it as propaganda, yet I would claim that the work is pro-Soviet. There is an important difference between those two. Propaganda aims at affecting your mind, in many ways forcibly implanting strong emotions towards a subject. Vertov strove to showcase a futuristic city that would serve as a commentary on the ideals of a Soviet citizen while granting us the freedom to decide our emotions regarding it.
Considering that it still would be possible, did I feel like packing my belongings and leaving for good? I would not say so for two reasons. I adore the work ethic and optimism that was shown through the film, where a lady would be doing a tedious manual task of wrapping up tobacco packages, while still talking and presumably laughing at some jokes throughout her work. However, I do not feel I personally share many of the Soviet ideals shown in the movie, but they do have my respect. The second reason is that we are mostly presented with the active urban life, but an overwhelming majority of the Soviet population used to live in more rural areas, where I would imagine the lifestyle was very different.
After an epilepsy-inducing final scene, the end credits simply read KINEC (END). I started applauding because I felt this is what Man With A Movie Camera deserves. There was no doubt in my mind that Vertov showed the infinite possibilities of what cinema can be. You just have to let the camera do the talking.
This review for Man with a Movie Camera was written for graduate film course on Soviet Cinema. Original can be found here. ◼

The identity permutation is defined as the permutation of given numbers in their natural order. The identity permutation of first natural number is given as . Also, it is known that n! permutations are possible with n numbers.
• Now, consider the given PERMUTE-WITHOUT-IDENTITY algorithm. Using this algorithm Professor Kelp wants procedure at random any permutation besides the identity permutation.
• That is , the Professor kelp wants to produce any one of all possible permutations(n!) of array of n elements, except the identity permutation(i.e. 1,2,3,….n).
• Thus the PERMUTE-WITHOUT-IDENTITY algorithm must produce any one of the n!-1 permutations.
The given PERMUTE-WITHOUT-IDENTITY algorithm will not produce the identity permutation, also it fails to produce some other permutations.
Now consider the PERMUTE-WITHOUT-IDENTITY algorithm for. So, for ,
the total number of permutation besides identity permutation will be calculated as:
That is, the PERMUTE-WITHOUT-IDENTITY algorithm must produce 5 random permutations besides the identity permutation.
For, the for loop, in the PERMUTE-WITHOUT-IDENTITY algorithm, iterates for and .
For first iteration ( ):
• When,, the RANDOM(2, 3) function will return the values either 2 or 3.
• Thus, only two permutations are possible in the first iteration.
For second iteration ( ):
• When,, the RANDOM(3, 3) function will return only a single value which is 3.
• Thus, only one permutation is possible in the second iteration. Also this permutation can be produced in iteration one.
Therefore for n=3, the total number of possible permutation produced by PERMUTE-WITHOUT-IDENTITY algorithm is 2 rather than the 5 permutations.
Hence, the PERMUTE-WITHOUT-IDENTITY algorithm does not produce what Professor Kelp intended.
Consider the given PERMUTE-BY-CYCLIC algorithm.
• 1st line initializes a variable n with the size of array A.
• 2nd line declares an empty array B to store permuted elements of array A.
• 3rd line generates a random number between 1 and n and stores in offset.
• 4th line implements a for loop to permute elements of A by storing them in B at different positions.
• 5th line adds i to offset and stores the result into dest.
• 6th line checks the index value dest is greater than n or not. If condition is true, then resets the value of dest by performing modular division.
• 8th line stores the ith element of A into B at position dest.
The PERMUTE-BY-CYCLIC algorithm randomly selects a value between 1 and n as offeset. The index dest is determined by adding i to offset. If dest is greater than n, dest is updated by perfoming modular divisionon dest with n( dest=dest-n or dest= dest % n). This procedure generates a cyclic rotation of the array.
However, each time, the value of dest is between 1 to n. Thus, each element of A may save at any one of n positions (indexes) of B. Therefore, the probability of an element A[i] to store at one position of B is 1/n.
An algorithm is said to be produces uniformly random permutations on a set of n elements, if the algorithm can produce n! random permutations with each permutation is equally likely to appear( That is, each permutation should have probability 1/n!).
Therefore, the PERMUTE-BY-CYCLIC algorithm does not produce uniform random permutation, because it determined only one offset(one random number) for whole permutation with probability 1/n. Hence, it only generates n random permutations. Each of these random permutations is occurred with probability of 1/n.
Hence, PERMUTE-BY-CYCLIC algorithm does not produce uniform random permutation.
Consider the algorithm PERMUTE-BY-SORTING(). To increase the uniqueness, randomly choose the elements of array P between 1 to.
Here, n is the size of the array P.
• For value of i, j such that, Consider that will denote that an element at index i and j are identical, in array P.
• Since elements in P are chosen independently at random from values 1 to, the probability that an element at index i and j are identical in array P,
Finding the probability that all elements are unique in array P:
• Assume, if elements at first i-1 index are unique, then the probability that the element at index i is unique, Pr{Ei} . …… (1)
• Therefore, the probability that all elements are unique is
…… (2)
• From equation (1) and (2), the above expression can be written as,
• This can be further solved to,
Hence, the probability that all elements are unique is at least.
Producing uniform random permutation
Consider the PERMUTE-BY-SORTING () algorithm that permutes the elements of array A by random priorities. Where, A is an array of n elements. The PERMUTE-BY-SORTING () algorithm may possibly generate or assign same priority to one or more elements in the array A. The algorithm can be modified such that the algorithm produces a uniform random permutation.
Now, consider the following modified algorithm of PERUMTE-BY-SORTING that produces a uniform random permutation.
MODIFIED-PERMUTE-BY-SORTING (A)
//Determine number of elements in the array A
1.
2. let be new array
//initialize the array P with numbers, 1 through n.
3. for to n
4.
5. for to n
//choose a random number between 1 and n
6. k = RANDOM
//swap the ith and kth elements of P so that no two priorities are not same.
7. SWAP
8. Sort A using priorities in P as sort keys
Uniform random permutation is achieved by assigning the priorities in increasing order 1 through n and in each iteration swapping the ith element and kth elements in P. Where, k is the random number chosen in the range 1 to n.

Ken Block Slides Around China's Most Dangerous Road In A 900-HP Truck
With 99 unforgiving corners and sheer cliff drops, Climbkhana 2 has to be Ken Block’s toughest challenge yet.
by Martin BiggFeaturing five locations and five different cars, Gymkhana 10 was Ken Block's most ambitious video to date celebrating ten years of torturing tires in the online viral video series. But don't think Ken Block is done burning rubber for our entertainment, because he's back with the second installment of the spin-off Climbkhana series.
Whereas the first Climbkhana featured Block taking on the Pikes Peak Hill Climb in a modified Ford Mustang, Climbkhana Two takes place on one of the world's most dangerous roads: Tianmen Mountain in China, also known as Heavens Gate. This is the same location where the electric Volkswagen ID.R recently set a lap record. But Block didn't go there to chase lap records.

"About five years ago, I found a photo on the internet of this crazy road made of multiple switchbacks that actually crossed over itself," said Ken Block. "Before I even discovered where in the world it was, I knew we had to go film there. As we did more research, I realized we may have found the greatest road ever. It's like a European tarmac rally stage - but turned up to 11 - and, it's set in a wild scene that looks stolen right out of the movie Avatar."
Located in Zhangjiajie, Hunan Province, China, the Tianmen Mountain Highway climbs 6.7 miles and features 99 unforgiving corners and dangerous sheer cliff drops. It's so dangerous, the public isn't allowed to drive on it. If you thought Pikes Peak was dangerous, Heaven's Gate is almost half as wide in places. There's zeromargin for error, and yet Block somehow makes it look easy. It's insane to watch.
"Over the past couple years, a few other projects have been filmed in the region, but we really wanted to bring our unique style of filmmaking and Ken Block's wild driving to this road to show it in a way it hasn't been seen before," said Climbkhana Two's Director Brian Scotto. "This road is amazing, but also very unforgiving, which ironically is its best attribute."
To make things even more challenging, Block used his 914-hp Ford F-150 Hoonitruck to tackle the incredibly dangerous and narrow road. It's both impressive and terrifying to watch, as Block expertly drifts around tight corners, performs tire-smoking donuts around obstacles, and narrowly misses barriers with inches to spare. "The juxtaposition of this massive American pickup truck and that tiny road was just too perfect, even if it made it way harder and sketchier to for me to drive," said Block. Question is, what will Ken Block do next to set the stakes even higher? We can't wait to find out.

There are some anti-obesity medications (Sibutramine (Reductil or Meridia)) or appetite suppressants that work on the brain and may help to reduce symptoms of food addiction. They also tend to have side effects such as they may increase blood pressure, cause dry mouth, constipation, headache, and insomnia. One may try to talk to their doctor about their food addiction, however, unfortunately, very few health professionals even know that food addiction exists, let alone how to treat it.
Typically, trigger or “unsafe” foods should be removed from the diet and boundaries should set so that managing these foods in a healthier way can be relearned. If someone binges on ice cream when he or she is stressed, it’s best not to keep it in the house. Eliminating the temptation until he or she can eat ice cream again in a balanced way is a safe option.
Surely only health can not be kept in mind, as sometimes one may also eat "junk food", however a moderation is a mandate. You must make a schedule, which lists the items that you wouldn't be having for a particular period of time, that one may list as "unsafe". Preferable go out for a meal, once a week and eat all the junk you can in that one meal only. But be very particular during the rest of the meals of the week to not have any of the food items present on your list. Find a sample list here

title: Running for the openSUSE Board (again!)
date: '2012-11-13 22:33:19 +0100'
categories:
- Board
tags: []
---
I guess I'm a sucker for punishment - after having such fun last year, I'm announcing my intent to run for the openSUSE Board in this years Board Elections
I've been using SUSE Linux since 2003 and contributing to openSUSE since the Project started.
I've got my hands dirty in many aspects of the project, from testing, packaging, working on branding and artwork, to providing support on IRC. I currently work mostly in the GNOME, Marketing, and Ambassador teams, and have previously worked on the Artwork team.
I'm an active Ambassador, who regularly attends conferences where I do my best to to both evangelise about our great project, but also gather ideas and feedback on how we could improve. I've been involved in the efforts to reshape the Ambassador programme into something more useful for openSUSE
My current 'day job' is as a Systems Manager for a college in the south of the UK which uses a great deal of Linux and FOSS technologies, including openSUSE.
Through that job, I currently hold a Board Member position of the TTP User Group, which consists of sysadmins of hundreds of Colleges internationally, all using SUSE/Novell/NetIQ products.
If I am elected to the board, my intention is to be an enthusiastic and active Board member.
I want to see our community grow in both numbers and activity. We need to be more vocal about our strengths, and most honest about our weaknesses.
I think we need to improve communication across the community, and I'd like to see the Board take a more active role in resolving any disputes.
I'd also like to see the Board stepping up to engage the community in helping out to address deficiencies or weaknesses in the project. I don't want to see the board starting to meddle in the affairs of development, but I do think situations like the delays to 12.1 could have been helped by having a board that is willing to speak up and call for the community to help out.
So when the Ballots open in a few weeks, please consider voting for me, I promise to do my best if I am elected.

Intestinal stem cell genes may link dietary fat and colon cancer
Study suggests tie between stem cell behavior and a high fat diet
| Source: | Rutgers University |
| Summary: | Two genes that appear to help stem cells in the intestine burn dietary fat may play a role in colon cancer, according to a new study. The study describes a new connection between the way cells consume fat and how genes regulate stem cell behavior in the intestines of mice. |
Two genes that appear to help stem cells in the intestine burn dietary fat may play a role in colon cancer, according to a Rutgers study.
The study, published in the journal Gastroenterology, describes a new connection between the way cells consume fat and how genes regulate stem cell behavior in the intestines of mice.
"This is important because scientists have shown that when there's too much dietary fat in the intestine, stem cell numbers increase, boosting susceptibility to colon cancer," said senior author Michael Verzi, an associate professor in the Department of Genetics in the School of Arts and Sciences at Rutgers University-New Brunswick. Verzi is also a research member in the Genomic Instability and Cancer Genetics Research Program at Rutgers Cancer Institute of New Jersey.
People naturally lose millions of intestinal cells daily, much like they lose skin cells. Intestinal stem cells undergo constant renewal and fuel the continuous turnover of the lining of the intestine, but altered stem cell functions can lead to colon cancer.
Colorectal cancer (of the colon or rectum) is the third most common cancer diagnosed in both men and women in the United States. An estimated 101,420 Americans will be diagnosed with colon cancer this year, according to the American Cancer Society.
Recent studies have shown that intestinal stem cells can increase in animals on a high fat "Western" diet, potentially explaining an elevated cancer risk from such a diet.
The Rutgers team recently discovered that two genes (HNF4A and HNF4G) work together to promote the proper function of the intestinal lining. In the new study, they found that mice lost intestinal stem cells when these genes were inactivated, confirming their importance. Rutgers scientists believe that the genes help stem cells burn fat, providing them energy.
Going forward, the researchers hope to further investigate whether the two genes alter stem cell numbers and cancer risk during a high fat diet, said Verzi, who is also a member of the Rutgers Center for Lipid Research.

Digital Signature Solutions
Digital signatures are like electronic “fingerprints.” In the form of a coded message, the digital signature securely associates a signer with a document in a recorded transaction. Digital signatures use a standard, accepted format, called Public Key Infrastructure (PKI), to provide the highest levels of security and universal acceptance. They are a specific signature technology implementation of electronic signature (eSignature).
The term digital signature is used to refer to a category of e-signatures which are created using Public Key Cryptography (PKC). However, practically the only way to implement these is to use digital signature based on PKI. Digital Signature is a process that guarantees that the contents of a message have not been altered in transit.
When you, the server, digitally sign a document, you add a one-way hash (encryption) of the message content using your public and private key pair.
Your client can still read it, but the process creates a “signature” that only the server’s public key can decrypt. The client, using the server’s public key, can then validate the sender as well as the integrity of message contents.
Whether it’s an email, an online order or a watermarked photograph on eBay, if the transmission arrives but the digital signature does not match the public key in the digital certificate, then the client knows that the message has been altered.
Three core security services provided by digital signatures
Signer authentication
Proof of who actually signed the document i.e. digital signatures linking the user’s signature to an actual identifiable entity.
Data integrity
Proof that the document has not been changed since signing. The digital signature depends on every binary bit of the document and therefore can’t be re-attached to any other document.
Non-repudiation
The signer should not be able to falsely deny having signed. That is, it should be possible to prove in a court that the signer in fact created the signature. Conversely it should not be possible to falsely claim that someone signed a document when they did not.
The most common way of creating a digital signature is to use Public Key Cryptography (PKC). The systems used to deliver PKC are called Public Key Infrastructures (PKI). At a basic level digital signature solutions require each user to have a public and private key pair which are mathematically linked. The private key remains under the owner’s sole control and is used to sign. The signing process creates a crypto code, which is embedded into the document.
A PKC based digital signature is based on the following security principles:
There is no way for anyone to work out someone’s private key from their public key. This is because PKC is based on hard mathematical one-way problems, e.g. like factoring a large number which is the product of two primes.
The private key is under the sole control of the owner. This can be held locally by the user (e.g. on a secure smartcard/USB token), in this case the signing process is referred to as “local signing”. Or the private key can be held centrally in a Hardware Security Module (HSM) – a tamper-protected hardware component. In this case the signing process is referred to as “remote signing”. The key is only released to the user after successful authentication using either single or multi-factor authentication.
