A Utah Mormon missionary seriously injured during a bombing at the Brussels airport is now in a medically induced coma.
The family of 66-year-old Richard Norby of Lehi said in a statement issued Wednesday by the LDS Church that shrapnel caused severe trauma to the man's lower leg, and he also suffered second-degree burns to his head and neck.
After a lengthy surgery, he is now expected to stay in a medically induced coma for a few days.
His family said a lengthy recovery is expected.
His wife, Pamela Norby, wasn't at the airport when the explosions happened Tuesday.
Norby, a former teacher and administrator in the LDS Church Educational System, also served as a mission president in the faith's Ivory Coast Abidjan Mission from 2003 to 2005.
The Church of Jesus Christ of Latter-day Saints said 20-year-old Joseph Empey of Santa Clara and 19-year-old Mason Wells of Sandy were also seriously wounded but have been awake and spoken to their families.
Empey and Wells both have undergone surgery, according to statements from their families. Empey was treated for shrapnel injuries to his legs and for burns to his hands, face and head. Wells underwent surgery on his Achilles tendon and was treated for burns and shrapnel injuries.
Also injured was missionary Fanny Rachel Clain, 20, of Montélimar, France.

Sega wants to celebrate his anniversary in style.
in Gaming Column
No, you're not seeing things. (Well, maybe old age.)
Sonic the Hedgehog officially turns 30 this year. The icon's first video game adventure debuted in 1991 on the Sega Genesis, creating a lightning fast journey that would include sequels, spin- offs, animated TV shows and even a big-screen film featuring Jim Carrey as his ruthless nemesis, Dr. Robotnik.
And yet, things are just getting started for the little 'hog that could. For this year's anniversary, Sega states that it has big plans. We already know a film sequel is in the works, and there could be a TV series over at Netflix as well.
But that also includes some new game announcements. Sonic's been kinda quiet since Team Sonic Racing debuted a little while back, aside from some other game appearances. But here's some guesses as to what the publisher could have in store for the fast little hero and his crew.
Here's hoping we see at least one of these surface.
Sonic Colors HD
Initially released in 2010, Sonic Colors has become a sleeper hit for both Wii and Nintendo DS owners. However, it seems that no one else has been able to enjoy this, leaving its audience somewhat limited. An HD release would hit the spot, with remastered visuals, lightning speed and more gameplay features to attract players to this, ahem, colorful adventure. It's well worth discovering, so, yeah, we'd be all for its return.
Sonic Chronicles: The Dark Brotherhood Sequel
As trippy as it sounds, Sega and the developers at BioWare did team up at one point to create a savvy Sonic role-playing game called Sonic Chronicles: The Dark Brotherhood. And though it wasn't as wildly popular as his platforming adventures, it still garnered a pretty good audience.
That should give Sega all the more reason to give the formula another try with a sequel, introducing new characters and tactics while continuing the intriguing story. Granted, BioWare is a bit busy these days with all things Mass Effect (and, yeah, Anthem), but you never know.
After all, we got another Paper Mario on Switch, so anything is possible. In the meantime, seek out this gem if you can.
For years, the Sonic Adventure franchise has been buried, staying roughly in the past on the Sega Dreamcast and Nintendo GameCube with the first two entries. But why is that? It has a pretty strong following, and many people have been vocal about seeing a third chapter come about. So the 30th anniversary could very well be the best time to introduce it, as we can't get enough of the enjoyable 3D gameplay. What else can we say but "Follow me, set me free!"
Sonic Mania 2
Perhaps it's too soon to ask since the first game is still fresh in our minds, but we would not turn down a sequel to the highly addictive Sonic Mania. A platformer that meshes together elements of the old and the new, Mania turned out to be a genuine surprise. So we're open to the idea of getting more of the same – and maybe with more multiplayer options this time.
(Even if that means someone playing Tails. Ah, well.)
Sonic And All Stars Racing Transformed 2
Team Sonic Racing isn't a bad little endeavor, as it delivery speedy thrills around every turn. But every driving fan out there really wants a sequel to Sumo Digital's 2012 release, Sonic and All Stars Racing Transformed. Everything about this game came together beautifully, making it a worthy rival to the unstoppable Mario Kart 8. Having more tracks and obscure characters from the Sega universe would hit the spot. And, hey, maybe a playable Ristar? Just saying.
No disrespect meant to Sonic Forces – it's not bad to say the least – but we really want to see the Generations open up again. The 2011 release was amazing, blending classic level design with 3D platforming antics almost effortlessly. And the sequel, if it ever does come around, could do the same, with even more inspiration from classic games, more gameplay features and, of course, that radical music making a return. Fingers crossed on this one.
What Sonic game do you hope to see announced in 2021? Let us know.

Good Luck Chuck {Sriracha Sunflower Soup and Sunflower & Honey Swirl Ice Cream}
When a story begins, "It was a dark and stormy night. . . " you know it's going to be good.
We were looking over the menu at The Kitchen in downtown Denver after a brief and rather bumpy round of introductions. I could see the passion in his eyes as he started to tell me the tale. I'd been looking forward to hearing the story of Chuck for weeks.
"I was driving down on a south Florida highway in the pouring rain..." he went on. Having lived in Florida myself for several years, I knew just the kind of rain he was talking about. Rain that comes down in volatile, horizontal waves, like sheets on a clothesline, thrashing in the wind.
Our drinks arrived and he paused briefly to marvel at the colour of the Chardonnay. It was a stunning shade of coral.
"It was a busy highway, and there was a lot of traffic going both directions," he continued, "but out of the corner of my eye I saw a man on the side of the highway. I glanced in the rear view mirror as I sped past and saw that the man was pushing an empty baby stroller and cradling something under his sopping trench coat..."
Most of us would have driven on by with little more than a passing thought... "better him than me." But not my new friend. I was discovering, through that first conversation, the principals on which he's built his life. One is: if there's a way to change the world for the better, go for it. As such, when he glanced again at the man growing smaller in his rear view mirror, he knew he had to do something. So he pulled a U-turn and circled back around, pulling off the highway to help.
"...I heard the crying as soon as I opened the door. The man was cradling a tiny baby girl, trying his best to shelter her from the pounding rain within the folds of his soaking coat. She was inconsolable, and having just become a new father myself, my heart went out to these two strangers."

A lot of developers deploy their apps on a Kubernetes Cluster that is "managed by someone else"™ like Google, Amazon, Microsoft or the ops department. This also means someone else is responsible for securing the cluster, right? Wrong! Well, at least that's not the whole truth. There are plenty of security options available when using K8s: RBAC, securityContexts, Network Policies, PodSecurityPolicies, Kernel Security Modules, Services Meshes, etc.
But which ones are relevant for developers? And which are the most important ones?
In this talk, I will describe my personal K8s security best practice established throughout the last years while developing applications on Kubernetes clusters. It contains security options that can be applied with reasonable effort in our everyday lives as software developers and shows the effects of these options on our application's security.

That is what Citroen calls the latest version of its quirky C4 Cactus. The hatchback has received a major overhaul for the new year, including high-tech suspension and revised styling details. Rest assured, the 2018 Citroen C4 Cactus is going to stand out in its segment like the Chinese kid in the Jolie-Pitt family.
The suspension system which the French auto maker claims makes 2018 Citroen C4 Cactus the most comfortable car in its class is a Progressive Hydraulic Cushion affair with secondary hydraulic dampers. They deliver a sort of 'magic carpet ride' which isn't perfect, at least it wasn't on the previous versions of the car, but is considerably better than the standards of the hatchback class. And that's on its own is enough reason to consider the Cactus. A nice and smooth ride is something car makers don't really care about with their smaller models.
But PHC is not the only comfort feature of 2018 Citroen C4 Cactus. The hatchback comes with new, thicker foam for the seats which are ideal for longer drives. One fears one might fall sleep behind the wheel of the Cactus, what with these seats and that suspension. Visually, the new model does away with prominent Airbumps – thank heavens for that – and instead introduces a couple of discreet ones on the side sills. So you still get the rugged look and the protection, but your car doesn't look like it has a tropical disease. Another highlights of the 2018 Cactus C4 is the addition of a 128 bhp three-cyinder PureTech with peppy performance.

How to Keep Your Home Safe Protected While on Vacation?
#1 How to Keep Your Home Safe Protected While on Vacation?
It is not uncommon for people to become stressed out for the holiday season, but a vacation should be a time that allows you to relax and clear your mind. With most of our valuables locked up in safes, it can become harder to not be stressed out and the rising rate of crime all over the world does not make this easier. There are certainly a few ways for you to reduce the risk posed to your safe and valuables and these can be costly, but I like to let you know the most affordable methods that allow you to keep your safe secured during the holiday season.
Keeping your home safe protected is something that needs to be considered throughout the year and not only when on holiday and these 7 tips will help you improve the overall security of your safe and even help keep that office and vacation home safes secured when you are not present. So what are these tips and how can they benefit you from a vacation standpoint?
Criminals tend to befriend people under fake names to try and gain information on the person and to see if they leave any information that might be advantageous to them. If you manage to keep all your travel plans offline, you should be able to boost the anonymity of your travels and thus the intruders will not have any knowledge that the home is empty. This method will not cost you anything and when you start making this a habit, your overall home security will be improved when you go on vacation.
We all know how bold intruders can be and that they are even willing to try and steal your things when you are at home. By faking that you are not away, the intruder will need to do more research and recon to see if you are home and by the time they figure out that you are gone, it might be too late and then you are back. Automatic light timers will be great and they will also symbolize the illusion that somebody is still home. This could dissuade intruders from taking a chance and they will rather move on.
When intruders enter your home, they generally have a few spots they search first, but if the safe is concealed in a secret place, they might not be able to find the safe and in return, they will also be more likely to trigger an alarm or simply just move on and consider the house to be a bust. If you have a home security system with a silent alarm, it will also give the security company more time to try and locate the intruders and perhaps catch them red handed.
While not everyone has the finances to do this, it could really make life much easier for you and you will be able to carry some of your valuable with you. The safe does not necessarily need to be small and those bigger trunk safes can also work perfectly for carrying your weapons, but I do not recommend carrying your entire arsenal of weapons with you as this might make you a target.
Motion detectors can do wonders when it comes to the outdoor areas of your house, but the problem is that they can be seen and intruders will be able to prepare accordingly to try and avoid or disable them. By adding one or two of them in your house and even close to the areas where you close your safe, you will be able to alert the security company from the inside of your home and this will catch the intruders off-guard. If you manage to install silent alarms, it could also allow authorities to catch them red handed.
Intruders will try to be quick during the holiday season and this is due to the fact that they will try and target multiple places and they know that authorities are more alert. By having your safe securely mounted, you will force the intruder to try and pry open the safe and this could cause them to take longer and cause more noise. Having a securely mounted safe is beneficial throughout the year and it also offers another layer of protection to your home.
Nothing will improve your confidence more than knowing you have a high-quality safe. Should you decide to purchase a higher quality safe, you will have much more peace of mind and not even the elements will be able to break your safe. I always recommend the SentrySafe Company when it comes to high-quality safes and you can check out a few of our safes from them to help put your mind at ease.
By following these tips, you should be able to relax and enjoy the holiday season without any break in fears and if they break in, you will know that they cannot steal the safe. I hope that you are now able to keep your home and safes secure for the holiday season. I will be happy if you let us know about your holiday safe tips and how you keep your home and safes secure from intruders. Also I would like anyone with experience to let me know what kept your safe secure from the intruders.

Q: Why is stringless supergravity not considered by many to be a candidate theory of quantum gravity? This paper seems to show that $d=4, N=8$ supergravity is finite.  Yet the paper only has three citations in spires, and I certainly haven't heard talk of a new candidate theory of gravity.
Why isn't perturbative supergravity with some supersymmetry breaking principle, coupled with the standard model considered a possible theory of the universe?  Has someone checked the coupling to matter?  Is that the problem?

A: There has been a recent spate of interest in computing high loop quantum gravity without strings.  In my opinion this is a huge laborious effort to capture what lies in string theory already.  $N = 8$ SUGRA with an $SU(8)$ symmetry plus an $E_{7(7)}$ symmetry which acts independently.  The $SU(8)$ acts upon the $133$ dimensions of the $E_(7(7)$, which we can think of for $E_{7(7)}({\bf R})$ as $133$ scalars.  The $133$ real parameters of $E_{7(7)}$ are ${\bf 133}~=~{\bf 28}~+~{\bf 35}~+~{\bf 35}~+~{\bf 35}$, where $\bf 28$ is an $SO(8)$ and combined with ${\bf 35}$  is an $SU(8)$.  The current is composed of these scalars as
$$
J_\mu=~\sum_{a=1}^{133}J_\mu^a e_a
$$
with the current conservation rule $\partial^\mu J_\mu~=~0$  If with fix the $SU(8)$ this is a coset rule $E_{7(7)}/SU(8)$ which subtracts out the ${\bf 28}~+~{\bf 35}~=~{\bf 63}$ of $SU(8)$ are leaves $70$ scalars. Thus we may think of $E_{7(7)}$ as
$$
E_{7(7)}~=~SU(8)\times R^{70}.
$$
The coset construction removes trouble some terms or provide counter terms.  It is then possible to compute currents, which are Noetherian conserved, in this coset construction which up to $7$ loops is $UV$ finite.
The $E_{7(7)}({\bf R})$ is broken into a discrete group $ E_{7(7)}({\bf Z})$ by "quantization," which in turn  contains the modular (or Mobius) group $SL(2,{\bf Z})$ of S duality and the T-duality group $SO(6,6,{\bf Z})$.  The Noether theorem operates for continuous symmetries, not for discrete ones.  However, a braid group or Yang-Baxter arguments may recover current conservation.  Further, a more general U duality description which meshes S an T dualities together may conserve current.  So there are open questions with the construction which have not been answered.  In an STU setting the lack of Noetherian currents should be replaced with Noetherian charges associated with qubits.
For $N~=~8$ and $d~=~4$ a paper by Green, Ooguri, Schwarz
http://arxiv.org/PS_cache/arxiv/pdf/0704/0704.0777v1.pdf
it is not possible to decouple string theory from SUGRA.  There exists a set of states which make any decoupling inconsistent.  This calls into question the ability to compute the appropriate counter terms required to make a consistent SUGRA which is $UV$ finite. This paper attempts to circumvent this problem, but it must be realized this is a $7$ loop computation of considerable complexity which recovers results of string theory that are obtained rather readily.
These efforts are not without purpose though, for the construction of Noetherian currents, which I think will correspond to Noetherian charges associated with qubits and N-partite entanglements in STU theories.  However, as a replacement for string theory, reduction of gravity to a pure QFT, I doubt this will ever prove to be a complete approach.

A: In order to not be entirely negative, I'll answer your question first and then provide a reason or two why research on the subject is interesting for other reasons.

*

*The finiteness conjecture  has to do with perturbation theory. Even if true, it is still believed that in order for the theory to be non-perturbatively finite and otherwise consistent (e.g unitary), it has to include more degrees of freedom. The most plausible scenario is that the completion is the full string theory, for which N=8 SUGRA is very closely related.

*The theory does not have enough structure to be a realistic description of nature by itself. For example it does not have chiral fermions, or a mechanism to break the extended SUSY spontaneously. All of these things become possible when you embed the theory within string theory.

*If you keep the theory as a QFT, but add some ingredients by hand to get more a realistic theory, the extended SUSY is broken and the magic is gone. Any finiteness conjecture is only valid for the pure (super)gravity case, and goes away as soon as you make the situation slightly less symmetric.
On the other hand, purely as a theoretical laboratory it is fascinating that a quantum field theory which contains gravity is better behaved than expected, and the theory has a close relationship to other highly symmetric quantum field theories (for example N=4 SYM). There is great excitement and hope recently that by understanding precisely why it is finite (or at least well-behaved) we'd be able to understand the structure of quantum field theories better. It is in some sense the "simplest quantum field theory" (arxiv.org/abs/0808.1446).

A: Dear Jerry,
the $N=8$, $d=4$ "non-stringy" supergravity is

*

*non-perturbatively inconsistent

*unacceptable phenomenologically

Trying to fix either of these things leads one to string/M-theory. See

Two roads from $N=8$ sugra to string theory
http://motls.blogspot.com/2008/07/two-roads-from-n8-sugra-to-string.html

The perturbative inconsistency may be seen in many ways: for example, the supergravity theory has $U(1)$ charges but produces no charged objects with respect to these $U(1)$'s. That's inconsistent because at least a newly formed black hole may confine these electric and magnetic fields and become charged.
The electric and magnetic charges have to be quantized in inverse units, as seen by the Dirac quantization argument. It follows that the noncompact continuous exceptional $E_{7(7)}$ symmetry has to be broken to its discrete subgroup, the U-duality group. There are many ways to choose the lattice of allowed charges. These ways are related by the original continuous symmetry. In decompactification limits, the lightest of these charges (with smallest spacing) may be interpreted as Kaluza-Klein momenta with respect to new dimensions, and one discovers the 7 compactified dimensions of M-theory. It may also be showed that the other charges inevitably have the shape of string/M-theoretical membranes and fivebranes.
There's no doubt today - and since the mid 1990s, in fact - that the supergravity theory is just a perturbative approximation to string/M-theory which is also why the supergravity community has been fully merged with the string/M-theory community. The people realize that they are working on the same theory and they are saying the same things. Ask Michael Duff.
Phenomenology
The maximal supergravity in four dimensions is left-right symmetric, and the high supersymmetry leads to too huge degenerate multiplets where spins differ by as much as $2$. The only acceptable supersymmetry is the minimal one where spins differ by $1/2$. The maximum supersymmetry implies that left-handed neutrinos couldn't exist and for each particle, there would have to be lots of very different superpartners. One couldn't get matter and gauge fields decoupled from gravity etc.
The maximum supersymmetry cannot be broken down to a smaller one by field-theoretical mechanisms - except for an explicit breaking that just destroys all the finiteness virtues of the supergravity. However, it may be broken at the stringy level, by appreciating the extra 6-7 dimensions, and compactifying them differently. The resulting models are compactifications of string/M-theory. They preserve the perturbative finiteness by the added stringy species and they also lead to realistic phenomenology with all types of matter and interactions that we know.
As Joe Polchinski said, all roads lead to string theory. In the case of attempts to overcome limitations of supergravity, the previous sentence is not a slogan but rather an accurate description of the situation.

Irrelevance, monotony, methods unsuited to solving real-world problems… Thoughts on preventing e-learning dropout.
Have you analysed the dropout rate for your e-learning modules? If they seem high, here are some pitfalls you should avoid, along with some useful concept and design tips to make your modules more effective.
Before you start to design a module, first take the time to define your target audience! The basic elements of effective e-learning depend on it, including course objectives, vocabulary and language level, choice of channels to be used, and so forth.
Ask yourself the right questions!
Are you speaking to managers or junior-level employees?
Do your learners need to understand and retain specific skills, or acquire more basic, quickly accessible knowledge?
Will your learners access content on a computer or mobile device?
Effective modules strike the right balance between telling, showing and doing! Avoid modules with too much text… They lead to cognitive overload! Only include essential content in your module. Divide your content into logic units that cover a single, easily digestible idea. Secondary information should be placed in an attached reference document.
Breaking up text with images and graphics doesn't mean choosing your photos by chance. No image is worth 1000 words if it's off-topic! If irrelevant, even the most stunning pictures will only contribute to cognitive overload!
What's the goal of your training course? To learn about a standard, become familiar with the foundations of a theory? Or to put a theory into practice, be able to solve a problem? The answers to these questions help to define evaluations that will meet your objectives and motivate your learners.
We often talk about the various tools and multimedia platforms, such as synchronised videos and slides, serious games and quizzes, which make e-learning modules interactive and stimulating. To be sure that your animations are not hard to download, first make sure that your learners' bandwidth and IT equipment are powerful enough. It would be a shame if a lack of technical foresight impacted your users' experience.

When I was a little girl I used to watch my mother knit sweaters for my dad and for each of her children. Some of them were pretty simple, but there was one I remember, that I think was based on an Irish Fisherman's pattern, that was more complicated and looked really beautiful in its better days. My dad wore it as a ski sweater for many years, and at some point it got hijacked by one of my sisters. Many years later, it was handed to me, with holes, almost as if it was a holy object, and I put it away in my closet.
I think most people know, or can remember a woman in their life who they picture in their mind holding knitting needles, an embroidery needle, a crochet hook, or even sitting at a loom. If you're lucky, they made something beautiful and useful for you. With the birth of my youngest son, I received two handmade baby blankets from elderly women here in Vallejo. One was knitted by Lilian Rivera, who had a long career in fashion design and especially with knits. She is the mother of my daycare provider, and when I come to pick up my kids, she will often grab a hook, sit me down, and fix the little snags on my sweater before allowing me to leave, a service for which I am very grateful! The other blanket was crocheted by Sammi Nobles. It has a bold geometric design, with tight little stitches and garnered many compliments while wrapped around my little boy.
Sammi's gift made me curious about this woman and her skills, and prompted me to meditate a bit on the whole story of women and textiles, bringing me to write this editorial during March, which is Women's History Month. Textile production goes back to ancient times. Considering that clothing and textiles are integral to the survival of the human race, weaving is perhaps one of the most miraculous skills people have managed to acquire all over the world. The design of looms, and the mechanization of the industry in more modern times may have been dominated by men, but the original technology almost certainly originated in the hands of women as they labored to but clothes on the backs of their husbands and children. They were all engaged in a constant search for better, more efficient, and also more beautiful ways to weave, crochet, knit and sew together the fabric of their clothes and communities.
From the Andean mountains, home of Vicu?a, Alpaca Wool and Pima Cotton, to the Burnt City where women living 5,000 years ago wore outfits similar to the sari worn by Indian and Pakistani women of today, beautiful fabrics were part of every day life. All ancient Egyptians, rich or poor, male or female, wore linen clothing, and of course the weavings of Native Americans are prized possessions among collectors. Quilts made in Europe and America that were once looked at as folk art, are now highly prized works of art worth thousands and sometimes millions of dollars.
If you look around you a bit, there is probably a woman in your life right now with skills. Here are short profiles on three women I know with skills and how they put them to use.
Do you have a story about a practitioner of the art of textiles that you would like to share? Please write a letter to the editor. We would be very happy to hear from you.
