Consider the metric space on, say, ℝ2 induced by the various $L^p$ norms, and the group of isometries from that space into itself that preserve the origin. When $p=2$ I get the continuous group of rotations, but when $p\in\{1,3,4,5,...\infty\}$ it looks like I just get $D_8$, the symmetry group of the square. Question: what's going on here? Why is 2 so special? Are there other natural norms on ℝ2 (or on ℝn) besides the euclidean one that give interesting isometry groups?
The following answer gives a partial description of the isometry groups of finite-dimensional normed spaces.
I assume that an isometry is a bijection preserving the distance function. By the Mazur-Ulam theorem it then follows that an isometry is a linear transformation composed with a translation. Thus we may assume without loss of generality that an isometry fixes the origin, so the isometry group is a subgroup of $GL(n)$.
Then the isometry group of any (real) finite-dimensional normed space is conjugate in $GL(n)$ to a closed subgroup of $O(n)$ that contain $-id$. This is seen as follows.
Consider the John ellipsoid $E$ of the unit ball $B$ of some $n$-dimensional normed space. This is the ellipsoid of largest volume contained in $B$ and, crucially, it is the unique such ellipsoid.
After some choice of basis we may assume that $E$ is the Euclidean ball. An isometry maps $B$ onto $B$, so it must map the John ellipsoid to the John ellipsoid. It follows that the isometry group is a subgroup of $O(n)$ containing $-id$. This subgroup is clearly closed, hence compact.
The converse is surely false. The following is an attempt at constructing a norm from such a subgroup. Fix a Euclidean unit vector $v$. Then its $Gv$ is a compact set of Euclidean unit vectors, symmetric with respect to the origin. Its convex hull $Gv$ is still compact and symmetric, so gives a unit ball $B_0$ of some norm on the linear span of $Gv$. If this linear span is not all of $\mathbb{R}^n$, then the unit ball has to be made full-dimensional in a sufficiently rough way, so as not to add any more isometries.
However, as pointed out by Leonid Kovalev in the comments, there are closed subgroups of $O(n)$, such as $U(n)$, where this construction gives a norm with a strictly larger isometry group (in the case of $U(n)$, the Euclidean norm).
As pointed out by Bill Johnson in a comment to his answer, it was shown by Gordon and Loewy that any $finite$ subgroup of $O(n)$ that contains $-id$ is the isometry group of some norm on $\mathbb{R}^n$. It's still my guess that the only way you can get infinite isometry groups (in the finite-dimensional case) is by having Euclidean subspaces, and for the norm to be so symmetric that it shares all the symmetries of this subspace.
I think what groups can be the isometry group of a finite dimensional normed space are classified, maybe by Y. Gordon and/or D.R. Lewis. I don't have access to emath from home but will check the reference tomorrow if no one has answered by then.
BTW: Banach-spaces would be a more appropriate tag IMO.
Consider the following norm on $\mathbb{R}^{2}$: $||(x,y)||$ := $|x|+|y|$ if $xy\leq0$; $||(x,y)||$ := $|y|$ if $xy\geq0$ and $|y|$ $\geq3|x|$; $||(x,y)||$ := $|x|+\frac{2}{3}|y|$ if $xy$ $>0$ and $|y|$ $\leq3|x|$. Then the group of isometries is { $\pm I\ $}.

A Generic Operational Simulation for Early Design Civil Unmanned Aerial Vehicles Benjamin Schumann, Jim Scanlan (School of Engineering Sciences University of Southampton); Kenji Takeda (Microsoft Research). Proceedings of the SIMUL 2011: The Third International Conference on Advances in System Simulation
Contemporary aerospace programmes often suffer from large cost overruns, delivery delays and inferior product quality. This is caused in part by poor predictive quality of the early design phase processes with regards to the operational environment of a product. This paper develops the idea of a generic operational simulation that can help designers to rigorously analyse and test their early product concepts. The simulation focusses on civil Unmanned Air Vehicle products and missions to keep the scope of work tractable.» Mehr lesen

Supply chain and hybrid modeling: the Panama Canal operations and it's salinity diffusion Mario Marin, Yanshen Zhu (American Technologika); Luz Alba Andrade, Erwin Atencio, Carlos Boya (Universidad La Latina); Carlos Mendizabal (Universidad Tecnologica de Panama). Proceedings of the 2010 Winter Simulation Conference.
This paper deals with the simulation modeling of the service supply chain and the salinity and its diffusion in the Panama Canal. An operational supply chain model was created using discrete-event simulation. Once complete, a component based on differential equations was added to the model to investigate the intrusion of salt and the resulting salinity diffusion into the lakes of the canal. This component was implemented in the AnyLogic simulation modeling environment by taking advantage of the concept of hybrid modeling that is embedded in AnyLogic.» Mehr lesen

Investigating Output Accuracy for a Discrete Event Simulation Model and an Agent Based Simulation Model Mazlina Abdul Majid, Uwe Aickelin, Peer-Olaf Siebers. 2009 INFORMS at University of Warwick, June 25-27, Coventry, U.K.
In this paper, we investigate output accuracy for a Discrete Event Simulation (DES) model and Agent Based Simulation (ABS) model. The purpose of this investigation is to find out which of these simulation techniques is the best one for modelling human reactive behaviour in the retail sector. In order to study the output accuracy in both models, we have carried out a validation experiment in which we compared the results from our simulation models to the performance of a real system. Our experiment was carried out using a large UK department store as a case study.» Mehr lesen
Toward Simulation-Based Real-Time Decision-Support Systems for Emergency Departments Yariv N. Marmor, Segev Wasserkrug, Avraham Shtub. 2009 Winter Simulation Conference (WSC'09), December 13-16, Austin, TX, USA
Emergency Departments (EDs) require advanced support systems for monitoring and controlling their processes: clinical, operational, and financial. A prerequisite for such a system is comprehensive operational information (e.g. queueing times, busy resources,…), reliably portraying and predicting ED status as it evolves in time. To this end, simulation comes to the rescue, through a two-step procedure that is hereby proposed for supporting real-time ED control.» Mehr lesen

The awareness of the greenhousegas effect and rising energy prices lead to initiatives to improve energy efficiency. These initiatives range from micro-generation, energy storage and efficient appliances to controllers with optimization objectives. Although these technologies are promising, their introduction may rise further questions. The implementation of such initiatives may have a severe impact on the electricity infrastructure. If several of these initiatives are introduced in a combined way, it is difficult to analyse their overall impact.» Mehr lesen

Custom Paint Tricks - You Name It We Flame ItWritten by on May 5, 2011 Learning Your Licks
In a swirling sea of leading brands, the "original recipes" are the most likely to survive. Now couldn't the same be said about flames? Let's face it, the oldest custom paint trick in the book has outlasted many a trend over the years. Does anyone remember graphics in pastel pinks and purples? Well, that's over and even the trendsetters of that era (at least the ones I'm acquainted with) are back on track with a whole new appreciation for the longer lasting basics, like scallops and flames, not tribal flames or ghost flames, but flames in traditional hot hues as our earlier influences intended 'em to be--the way we learned our licks.
Here we will demonstrate a time-tested basic approach to a sort of '60s-style flame job. We'll begin our symmetrical layout with tape, not with crayons as you've surely seen before. Our layout will flow with the curvatures of our canvas, our blends will be smooth, and although we do have unlimited access to a state-of-the-art spray booth nearby, we'll do this job in our dimly lit garage--for you. This is for the hobbyist or first-time flamer.
During the course of this seminar, we will not expound upon materials used, as materials are ever-changing depending partly upon your locality. By the time you've studied the following how-to, the materials we've used (leftovers in this instance) may already be obsolete, and/or unavailable where you live. More than anything, this is about the technique. With a little luck, maybe we can get you started right. If we can save just one poor ol' truck from another truly bad flame job--mission accomplished.

First we needed a canvas. Our friend, Ken, has been wantin' us to flame his ol' panel anyway, so he finally got the call he's been waitin' for. The existing finish ain't pretty, but it passed the tape test, so we're crossin' our fingers it'll stay put while we create the following 'three alarm' distraction.Worn, weathered, whatevered, it's best to treat them all the same. We won't begin this project 'til she's clean, so Ken got to scrubbin' on her bulbous body outside. We'll take the sterilization several steps further after necessary disassembly. This might even be fun.Here, Ken (left) and Mrs. Rotten (right) get to removing the hiccups, which would get in the way. The ol' girl practically fell apart (is that good?) by herself, and in a matter of minutes, she was ready for further chemical cleaning with grease and wax remover.This is what $52.03 worth of high-quality masking tape looks like – that's after our discount at our favorite paint store. Notice how the 1/8-inch (top left) looks old and overheated? I should have noticed that at the time of purchase; it's well beyond its expiration date.Who'll do the layout? We found this guy hangin' out in front of the paint store so we thought we'd give him a chance. With a centerline established, we'll work from front to back down one side only, using mostly ¼-inch tape, with 1/8-inch tape where the turns get tight.Several hours later, we have a layout. For a layout of this size, 1½-inch tape works well for fillin' the gaps, with ¾-inch tape as a necessary backup. See that tape ball stuck above the driver's door? That's the waste. Considering the amount on the canvas, it ain't half bad.Not only is the layout the most important part of any flame job, it's also the most fun part to do. If you try this at home, work with the lines the body already has, don't fight 'em or disregard 'em. It's important that your flames flow with the lines of your canvas.You might say "real flames don't burn symmetrical." However, if you say that around here, we might assume you're just lazy and unwilling to work for a symmetrical layout. A big flame job is a big job either way. Your layout is important, so no symmetry excuses here.
The 'pounce patterns' (that's what they're called) you see here will be laid down one at a time on a sheet of fiberboard, and then we'll pounce and pounce again 'til we have a complete set of reversible patterns to transfer to the B-side. Time spent here saves time later on.I once thought I'd never need a computer. Obviously I was wrong, but I can still say that I'll never need a computer for flames. Once pounced, we'll check each pattern by holding 'em up to the window. Light shining though the perforations confirms that we've done well.Here the pounce patterns are reversed and ready for the next step. Curvaceous bodies can present a challenge when flip-floppin' pounce patterns, but patience prevails as thoughtful cutting, folding, aligning, and taping pays off.What you're lookin' at here is chalk in a sock. Ordinary line chalk in a nylon stocking, when rubbed across the perforated pounce patterns, will leave a chalky dotted line to follow. It comes out quick and messy, but we'll vacuum up the excess before removin' patterns and movin' on.Over the years we've found it best to steer our tape just to the outside of the chalk dots, then blow the chalk away with clean compressed air. The outline is kinky and just a little larger than the other side at this point, but a second lap with ¼-inch tape will allow us some fine-tuning.After fine-tuning, some tape will be cut away where tips cross. Some prefer an X-Acto knife (clean new blades before use—they're oily), but a single-edged razor blade also works well. Double-edged razor blades are strictly for shaving and not recommended for flames at all.After filling in with ¾- and 1½-inch tape, we can begin sanding. Using the folded edge of our sand-paper (320-dry), extra attention is paid to the edges. Care must be taken not to rub the tape the wrong way, as this would destroy the details of the layout we've worked so hard for.Louvers are like speed bumps. They also distort flames. For those times when louvers can't be steered around, some thoughtful planning during the layout can go a long way toward minimizing distortion. Below the third louver down, we've carried a tip all the way through.
We're now ready for colors. Utilizing only environmentally friendly HVLP spray equipment, we'll be applying four shades of PPG's DBC base: Yellow, Orange, Oranger, and Poppy for the tips. DBC is tolerant of what could be considered over-reduction– more to come on that.We'll skip the test panels as we've used these colors before and we're certain that they'll blend together smoothly. The idea here is to achieve coverage with two coats of yellow. Our next colors up will be over-reduced as necessary to achieve smooth blends at low pressure.With our first color applied, and gun cleaned and reloaded, we'll continue to shade some over-reduced orange after testing our spray pattern. We don't want under-atomized droplets to spoil our blends. Extra reduction and smooth well-planned movements are the keys.Working from front (center of hood) to back, we continue blending orange over our yellow base. Knowin' where you're goin' comes not so much from practice as it does study. If there's a pyrographic artist whose work you admire, take some time to study their methods.We've now reloaded with our second orange (this orange is brighter and a little darker), which we'll stretch out smoothly across the wider sections of our flames. This is the first flame job Mrs. Rotten and I have done in our unfinished garage. It's actually dark in here.Now here's a trick for shading the hooks: By dialing the fan (spray pattern) down to a pinpoint and holding the gun further back from our intended target, these rounded areas can be shaded without even moving the gun. Just aim to the center, and trigger it in short spurts.Crossing tips is quick and easy, but crossing tips of different colors for extra definition is anything but. Once the majority of tips have been shaded with poppy, the ones that overlap must be masked as necessary to protect the colors that are already applied.This is not easily done in the dark, but we'll have the place well lit for the next one. Because DBC base colors flash off very quickly, we're able to do all of our shootin' in a single evening. However, sixteen crossed tips of contrasting color are slowin' us down considerably.
Time spent masking and reattaching crossed tips will be time well spent in the long run. The actual shading of these tips goes very quickly. Like taking the time to plan a symmetrical layout, crossing tips in livin' color will set your flame job apart from the average.Now that all our DBC base colors have been shot, we'll carefully remove the masking from our crossed tips, switch back to a larger HVLP clearcoat gun and hammer on a single coat of bargain basement generic urethane clear. We're intentionally holdin' back on gloss.For this job, using only a single coat of clear helps us in two ways; it'll keep our edges low for ease of pinstriping later and, because our canvas is not glossy, we don't want to overdo it. The clear we've opted to use is designed for spot repair, so it flashes off quickly.We still find this stage fascinating. Before the masking is removed, it's difficult to envision what the finished product will look like, but we know. When unwrappin' a flame job of this size, it's best to catch it at just the right time. Bring a buddy and pack your lunch if necessary.At this point, it's been a long, cold, dark, rainy night. Mrs. Rotten and I were in the garage well into the wee-wee hours as careful removal of this much masking material became a marathon.The legendary Lyle Fisk has agreed to wave his proverbial Mack #00 wand for us. Fisk has been draggin' his daggers for the fortunate folks of Southern California since 1955. In addition to striping, he does signs, gold leaf, wood graining, custom designs, logos and corporate ID. In fact, he's known for flames as well.Once a color decision is made, we'll clear out so Lyle can take his time. "That's a lot of flames," said Lyle. He also had some complements regarding our layout and so on, which feels pretty good, as he may have actually forgotten more about flames than we'll ever know.
Oh no, he's not hangin' it up or anything like that. Lyle tells us he'll never retire. He and his wife Yolanda are, however, makin' a move to Saint Augustine, Florida, where he'll continue building tradition, as he has since 1955. Attention Floridians: Our loss is your gain.With a whole new attitude, Ken's ol' panel seems to scream for a moniker. Ken likes the name 'Firecracker'. In this particular instance the poor condition of the canvas adds character. As anticipated, the crackly old lacquer finish is no longer what people notice and we're satisfied that we have successfully created the desired dramatic effect, a 'three alarm' distraction. Now dependin' on legalities in your localities, you just might be able to achieve similar results at home in your own garage. You name it–we flame it! Now, maybe so can you.

The construction of solvable polynomials
Abstract | References | Similar Articles | Additional Information
Abstract: Although Leopold Kronecker's 1853 paper ``On equations that are algebraically solvable'' is famous for containing his enunciation of the Kronecker-Weber theorem, its main theorem is an altogether different one, a theorem that reduces the problem of constructing solvable polynomials of prime degree to the problem of constructing cyclic polynomials of degree . Kronecker's statement of the theorem is sketchy, and he gives no proof at all. There seem to have been very few later treatments of the theorem, none of them very clear and none more recent than 1924. A corrected version and a full proof of the theorem are given. The main technique is a constructive version of Galois theory close to Galois's own.

Sometime in the past year or so while playing around in Sephora and Nordstrom stores, I started to notice that the Sin blush testers at counters did not look like the Sin I had at home. Similar, yes, but not the same. I started to think I must be crazy (and I think the sales associates did, too, when I mentioned it), so I bought a brand-new NARS Sin about a month ago to compare the two at home.
Here they are, side by side. On the left is the old NARS Sin, and on the right is the new NARS Sin:
I know, I know, they don't look much different. But look at the swatches! Again, old is on the left, new on the right:
I never heard anything about NARS blushes being reformulated. Have you, readers? Do you think this is due to a common reformulation, or has the color changed over the years due to quality control issues (either my old one changing color over time in the pan, or the batches from the factory changing over time because no one is bothering to keep them consistent)? More importantly, which version do you like better? :)

Form formula on view
Is there support for form formula on view?
I need to change the form used to load a document under some conditions. I tried to use the beforeopendocument, but it didn't work.
I appreciate any suggestions..

Good question. I'll look into this over the weekend.Jack Ratcliff

finally had time to look at this. If you add a form formula on the view then that form is what's loaded when you open the document from within a TabPanel. The Extnd code creates a iframe to load each document into. When you edit the document then it works as well. However, I do see a bug when you simply open a document directly (like http://yourserver.com/somdb.nsf/some...d?OpenDocument). After the doc is opened, you cannot use a action button code that has code like this:
I'll work on that bug. But how exactly are you opening documents?Jack Ratcliff

Disclaimer: This is not a homework problem. I stumbled on this puzzle on internet and I also have the answer. However I am not able to figure out whats the method to be used to arrive at the answer.
The puzzle is as below:
The product of the ages of David's children is the square of the sum of their ages. David has less than eight children. None of his children have the same age. None of his children is more than 14 years old. All of his children is at least two years old. How many children does David have, and what are their ages?
The answer happens to be 2,4,6,12.
Please suggest ways to solve this problem systematically.

The doctors and nurses at Seattle Grace have had a rough season so far, but perhaps none more so than the normally optimistic and cheery Arizona. In the plane crash that opened the season, the doctor was forced to amputate her leg due to injury and continues to cope. Actress Jessica Capshaw spoke with TV Guide about tonight's new episode, which will find her character continuing the struggle after developing phantom limb syndrome.
"It's completely terrifying. When we finished the table read, everyone was like, 'Whoa!' It's really creepy," Capshaw said of her character's new affliction. "It's really tonally different than a lot of the show. It kind of hits on a dream sequence that's lovely, but then it takes a sharp turn into this nightmare. I think it's incredibly compelling."
Phantom limb syndrome not only produces the sensation of a missing limb, but the crippling pain that goes along with it, something that Capshaw confirms will seriously inhibit Arizona's ability to work. "It's about the connection between your mind and your body, and there are different therapies that you can go through to try and come to terms with it. She's going to have to go through those, and yet, because of her not wanting to deal with it, and her feeling like she can keep working, she's bringing it to work with her and it's hard to be operating on someone when you're feeling excruciating pain in your leg like someone's cutting it off," the actress explained.
The affliction has proven to be a tenuous subject for Arizona and her partner Callie. "She's in denial with Callie. They're in a sweet spot right now, so I don't think she really wants to go back into the dark place and bring Callie back into the dark place with her. As Callie said a couple episodes back, 'It's always about the leg. It needs to stop being about the leg.' So she doesn't want to bring it up with her. She's ready to move past it. Her mind is ready to move past it, but now it's her body and her mind that are making it impossible. She ends up going to Owen (Kevin McKidd), because he recognizes in her what he recognizes in a lot of his military buddies and amputees, so he ends up helping her to find therapies that might make it easier," she said.
Still, the actress remains optimistic about the relationship between the two characters and the series' realistic portrayal of a couple in love dealing with a difficult issue. "I think that the most remarkable thing that you can say about them is that they are like any couple who love each other," Capshaw said. "They're still together. They're working on what they have to work with. It's challenging. Even when Arizona was blaming Callie for everything, there wasn't a love lost. It was never gone, it was just impossible for Arizona to see her way out of her grief. For me to play Arizona that way, in the first part of the season, was so hard because it's so unlike her. But that's what her circumstance made her. It's really just about moving on through your own stuff and finding your way back to being able to give your attention to that love."
Don't miss the new episode of "Grey's Anatomy" tonight on ABC!

Does is bother you when an online retailer doesn't email you an invoice?
I've seen several recently that don't email an order confirmation, a receipt, an invoice, or offer package tracking. It bugs me. Does it bug you? Why do you think they do this?
17 Answers answer
I haven't had that happen often, but when they don't send one it is annoying. I like to document my purchases. :)
While tracking is nice, I would prefer at LEAST a receipt to know that my order actually went through. Most companies I've ordered have been pretty good about this but some of them....
Yes, it bothers me. Feels like a lack of full service, or maybe like I'm dealing with a extremely small organization that doesn't have it's act together.
I do nearly all my shopping online, and I haven't run into a merchant that didn't send an invoice and a shipping notice. I'd be pretty leery of a company that didn't.
Yes big time! I ordered from Staples in the wee hours of the morning of Black Friday. When I finally settled down Friday afternoon and took stock of the damage. Upon checking my email I was very confused. I thought I must have been dreaming and didn't actually place an order. It wasn't until the weekend that I checked on Staples.com to confirm my purchase.
I've gotten so used to tracking information, and what might be considered a surfeit of emails (confirmation, processing, shipping, tracking), that I have been a bit nonplussed to encounter several voids this holiday season. One company is rather small, so I've chalked it up to lack of expertise. Another larger company stiffed me on communication, but got the package to me fast enough that I didn't fret too much.
The big thorn in my side is Office Max. I bought an item on Thanksgiving and got a confirmation. Five days later I got a message saying it would be shipped from a "different warehouse" and if the delay would be more than seven days they'd let me know. I have no idea which warehouse it was supposed to come from originally, or what date they were supposed to ship to which I can reference the "more than seven days." Its now over 7 days since I got that email and my order still shows as "processing." I can't believe Office Max can get away with this level of service.
It bugs me exactly as much as not ever getting my return business bugs them. If they don't care about my patronage, I don't let it bother me, I just add them to the list.
I hate that Woot! no longer emails the tracking number and you have to go under "stuff you bought," log in again, then look at the purchase, and click on the tracking number.
I've had this happen for the first time, twice in November.
I bought something from Virgin Mobile, on Black Friday, and I had to e-mail them to get a confirmation and tracking number.
I bought something from K-mart, and they sent me a confirmation e-mail, but no tracking information. In the confirmation e-mail, they said they would send me tracking information. I had to call them to get the tracking information.
What bugs me is when a company used to send the tracking # in the shipping update email, but now they just tell you it has shipped and force you to log into their site to get the tracking #. It was so much nicer to just copy the text from an email and paste it in my parcel tracking app. Now I get the email, click a link in it, log into the site, click the item, THEN I can copy the tracking #, log out of the site, close browser, and then paste it into the tracking app. Since they used to have the capability, the only reasons I can think of for not including the tracking # in the email are:
1) they want more page hits
2) they had security concerns of some kind
I at least want an email with the order number, amount, and list of things I bought, so that I can keep it in my suspense file until the order arrives and everything is all right. I just want the basics that they will ask me if I call them on the phone looking for my order.
That would definitely bother me, but I think I have always received at least a confirmation e-mail. What I really prefer to get is both an order confirmation e-mail and an order shipped e-mail which includes the tracking number.
It's also possible that the emailed order confirmation/invoice got caught by a spam filter.
I want to second @jsoko's comment! I deeply dislike that woot no longer includes tracking numbers in their shipping notifications. I assume that the rationale behind the change is so that they get paid for the additional ads that we "view" while pulling up tracking information, but this change has contributed to a decline in how many items I order from woot, especially when I'm comparing an item on woot to its equivalent on amazon.
I think I get an overabundance of emails when I buy online. I can't recall not receiving at least a confirmation online.
yup. i booked a hotel, said they would send me an email confirmation.... waits 2 weeks... no email. call and ask if i have a reservation, they say yup its right here!! still no email though
* i 3rd (seconded was taken) @jsoko's comment. WOOT needs to put tracking numbers back in the emails so i dont need to go in, get the link and email it to myself!

HARKER HEIGHTS (January 9, 2013)--RSBP Developers, Inc. has been given the green light to build a 100-acre housing development near Verna Lee Blvd.
On Tuesday the Harker Heights City Council discussed and approved the plan, though more details need to be sorted out.
Discussion got underway as to whether or not the subdivision, The Grove at Whitten Place, will connect to Tejas Trail to help distribute traffic.
Those opposed to the idea expressed concern over how well the new housing will sell if tied to an area that contains older trailer houses.
A possible solution that was proposed is that the developers put in a right of way where the two areas would have connected.
Construction is expected to get underway sometime this year.

I've made a mistake of moving my .vimrc file from my home directory and now I don't know how I'm able to locate it. I'm still new to Mac and navigating and finding files seems so foreign to me.
Instead of making another copy of my .vimrc file using 'cp' command in Terminal, I've dumbly issued the 'mv' (move) command. This is the command I've issued in my home (~) directory:
mv ~/.vimrc .old_vimrc
Now I can't find my original .vimrc file and can't even locate the '.old_vimrc' file.
Any idea where I can find it? I've wasted hours figuring it out and to no avail.
I'm trying to understand the 'mv' command I've issued above? Did it renamed the ".vimrc" file to ".old_vimrc"? Is that it?

For a boolean algebra B, let d(B) be the least cardinality of a dense subset of B. Let A be a (non-regular) subalgebra of a boolean algebra B. Is it possible that d(A) > d(B)? What if d(B) = $\aleph_0$?
Yes, it is possible.
Let $\mathbb{B}$ be any complete Boolean algebra with density $\aleph_0$. For example, we could use the power set Boolean algebra $\mathbb{B}=P(\mathbb{N})$, which has density $\aleph_0$ in light of the singleton sets, since every nonempty set contains a singleton.
Meanwhile, the Balcar-Franek theorem asserts that every infinite complete Boolean algebra $\mathbb{B}$ contains a free subalgebra of the same size. Thus, $\mathbb{B}$ contains a free subalgebra $\mathbb{A}$ on $2^{\aleph_0}$ many generators, obtained from strongly independent sets, as the linked article explains. Since $\mathbb{A}$ is free on $2^{\aleph_0}$ generators, it must have density $2^{\aleph_0}$.
So this is an example, for which $d(\mathbb{B})=\aleph_0$ and $d(\mathbb{A})=2^{\aleph_0}$.
The same reasoning establishes:
Theorem. Every infinite complete Boolean algebra of size $\kappa$ contains a subalgebra with density $\kappa$.
Proof. The Balcar-Franek theorem provides a free subalgebra of size $\kappa$, and by mapping the generators to atoms in another Boolean algebra, it is easy to see that such an subalgebra must have density $\kappa$. QED
Since there are numerous complete Boolean algebras with density smaller than their size, the theorem can be used to build numerous examples.
Addendum. In the context of forcing, it is natural to consider the case of complete Boolean algebras, for every forcing notion corresponds with a complete Boolean algebra $\mathbb{B}$, and the intermediate models of the forcing extension arise exactly from complete subalgebras of $\mathbb{B}$. A Boolean algebra $\mathbb{B}$ is complete if every subset of it has a least upper bound (and this implies one may take infinitary meets and joins). The density of the completion of a Boolean algebra (or a poset) is the same as the original density. A subalgebra $\mathbb{A}\subset\mathbb{B}$ is a complete subalgebra if infinitary meets and joins for subsets of $\mathbb{A}$, as computed in $\mathbb{B}$, exist in $\mathbb{A}$. In this setting, the density cannot go up:
Theorem. If $\mathbb{A}\subset\mathbb{B}$ is a complete subalgebra of a complete Boolean algebra $\mathbb{B}$, then $d(\mathbb{A})\leq d(\mathbb{B})$.
Proof. Suppose $D\subset \mathbb{B}$ is dense. For each $d\in D$, let $a_d$ be the meet of all the elements of $\mathbb{A}$ above $d$. This is an element of $\mathbb{A}$, and the set of all such $a_d$ is dense in $\mathbb{A}$, since for any $a\in \mathbb{A}$ there is an element $d\in D$ below $a$, and so $a_d\leq a$. Thus, we have produced a dense subset of $\mathbb{A}$ of size at most $|D|$, as desired. QED
Thus, when forcing, the relevant subalgebras arising from intermediate forcing extensions do respect the density.
Here is a construction that I think will work:
Take $B$ to be the Boolean algebra $P(\omega )$ with the usual operations. This has a countable dense subset. Now let $IC$ denote the collection of infinite subsets of $\omega$ with infinite complements. We will construct a family $A$ consisting of $\aleph _1$ sets, all of which are in $IC$, and such that $A$ is closed under complements, unions, and intersections; so after we throw in the nullset and total set, $A$ will be a subalgebra of $B$. It will also follow from our construction that $A$ cannot have a countable dense subset.
So here's the construction: we build $A$ inductively, in $\omega _1 $ countable stages $ (S _ \alpha ) _{ \alpha \in \omega _1 } $ which are cumulative. At each successor stage, we will add in a single new set to the previous stage, then close up under complements, unions, and intersections. So in fact there will be countably many new sets added at each successor stage. At limit stages we take the union of all previous stages. Note that each stage is closed under Boolean operations.
So we just have to say which new set $X$ we throw in at each successor stage $S_{\alpha + 1} $. We need to be sure that when we add in this new set and close up under Boolean operations, all the sets we get are still in $IC$. For this it suffices that for every $Y \in S_{\alpha}$, we have $X \cup Y \in IC$ and $X \cap Y \in IC$. In other words, $X$ and $\omega \setminus X$ must both have infinite intersection with every set in $S_{\alpha}$. And since by induction hypothesis every set in $S_{\alpha}$ is in $IC$, and there are only countably many of them, we can make our set $X$ by a routine diagonalization: for instance, we could line up pairs $(Y, n)$ for $Y \in S_{\alpha}$, $n \in \omega$ so that the pairs have ordertype $\omega$, and then go through them one by one, building initial segments of $X$ and $\omega \setminus X$ as we go to make sure that at the step $(Y, n)$, $X$ and $\omega \setminus X$ each have at least $n$ elements of $Y$ in them.
This completes the construction of $A$. Note that $A$ cannot have a countable dense subset, since any countable subset of $A$ shows up at some stage $S_{\alpha}$, and then at the next stage we added in a set which is not contained in any $Y \in S_{\alpha}$.
EDIT: A SECOND CONSTRUCTION. Here is another construction, which yields $2^{\aleph _0 }$ independent subsets of $\omega$. (Thanks to Joel for the hint about trees!) We will make a continuum-sized bunch of independent reals (subsets of $\omega$), by building their initial segments in $\omega$ many stages. The idea is that we are working our way up a binary tree, level by level, and so every level is finite; and at each such level, we ensure that no nontrivial Boolean relations can hold between two reals whose initial segments at that level are different. More precisely:
We represent subsets of $\omega$ as sequences of 0's and 1's, where $n$ is in the subset iff the $n$-th spot in the sequence is 1. So when we build finite initial segments of these sequences, we can specify some natural numbers to definitely be in the subset, and also specify some natural numbers to definitely NOT be in the subset. So: Start by making two different finite initial segments of reals, such that no nontrivial Boolean relations can hold between reals with those initial segments. (By 'nontrivial Boolean relation' I mean: nontrivial equation with Boolean connectives, where the only elements we have names for are the nullset, the total set, and the reals bearing the relation in question.) Since there are only finitely many possible nontrivial Boolean relations among a finite set of elements, and any particular relation can be forced to not hold by extending the initial segments in an appropriate way, we can get two different initial segments such that any two reals with these respective initial segments are already forced to not satisfy any nontrivial Boolean relations with each other. Next we fork each of these initial segments off into two longer initial segments; so now we have four initial segments, and we consider all possible nontrivial Boolean relations which could hold among these four elements. As before, extend the four segments until all such relations are forced to be false. Continue splitting segments into two, and forcing all finitely many possible Boolean relations to be false, $\omega$ many times. Then we will have a perfect binary tree of independent reals.

I have had to persuade "street vendors" of a different nature to leave the corner in front of my gallery several times.

I agree with Mr. DeLind. He pays a premium for that corner and shouldn't have to put up with finding a pile of garbage all over the sidewalk in front of his business. If it were me, I'd put a sculpture on that corner to block the vendor's access.

Umm.... he does know that his spot is in the middle of a city doesn't he? If he doesn't like this then I'm sure some boutique location could be found in door county or elsewhere. When you're located in the city you have to learn to take the good with the bad. I live right off of Brady St. so know what it's like. Oh, and I have two beasties in my living room just for the record. Maybe we could position the Fonzi statue right there on that corner, maybe he could even be riding a beastie!
When the sidewalk in front of your bar, restraurant or fine art gallery is dirty, you clean it. We don't need legislation for this. Or do some people just think they are more entitled?
OUCH! I guess I get no sympathy from you, Mary Louise. Perhaps if you had seen other e-mails that have gone between the alderman and myself, you'd see that I'm not asking the street vendor to disappear, only move his cart to the other side of the sidewalk, of course this would deprive him of the seat on my window ledge.....
Seriously.....the people who buy the hot dogs, are generally the younger crowd that have been out to the several night clubs....the people I seek to attract are those that are comming and going from the 8 fine restaurants within a block of my corner.
I also think I caught a disparaging remark about the Beasties. Milwaukee's original iconic sculpture, by Dennis Pearson. For shame. There is nothing wrong with art that makes you smile. The Beasties have brought joy and pleasure to thousands over the years, from Torry Folliard, Judy Posner and Juililly Kohler, prior to my taking over for Dennis 20 years ago. National Poet Lauriet Maya Angelu has 2 at her N.C home, and spoke about them making her so happy, being her "favorite sculptures" when she was interviewed on Opra Winfrey (who also has Beasties). Or that Dennis Pearson was invited to exhibit at tThe White House, for the Easter Egg Roll and who can forget the 2 Milwaukee Symphony Orchestra League's highly successful "Beastie Beat" events....one pictured here in your blog....that raised over $500,000 for the youth music projects of the Milwaukee Symphony Orchestra, as well as pumping over $50,000 into the arts commumity, with payments to other artists to dream and decorate.
If Beasties are not, in your mind, "real art", the hot dog vendor also blocked the view of my Camille Pissarro Painting, valued at over 1 million dollars. And he is now blocking my show of Russian impressionist and plein aire paintings. Yes, I hope I always remain a 'good sport', life is too short to do otherwise. I will be interested to hear what others think of my plight. Besides, the seagulls love this corner on Saturday mornings.
really, TomB? day after day Mr. DeLind should spend 20 minutes cleaning the sidewalk because someone other businessman is too lazy and inconsiderate to clean up after his own business and customers?? a guy who probably pays less than $200/year for his vendor permit? i'm sure Bill DeLind pays $3000-$6000 a month (if not more) for that prime location. But money is not the issue. i think at the very least someone like Mr. DeLind, who does a lot for the community, is ENTITLED to the respect of a fellow human being. Sesame Street 101 taught us to pick up our own trash and not thrown it on our neghbor's lawn.
It is inappropriate for the vendor to sit on the window ledge of the building. His permit is only for the public way. I'll take a Fiberglas Beastie over a Bronze Fonz any day. North Shore to the Core!
I marvel that the Editorial Board of the Journal Sentinel endorsed a sculpture of the Fonz sight and artist and location unknown. Tim Cuprisin of the Journal Sentinel had an excellent idea if we must honor our television sitcom "heritage" let's create a sculpture of a large bottle with a glove draped over it, Claes Oldenberg style.
Michael Horne
When Mr. Delind moved his gallery from the Cathedral Square
location I was thrilled. Such a great venue! Now his gallery can be seen top to bottom by everyone passing by. The hotdog vender
could move over so that it ALL can be seen. As for the BEASTIES,
they are a part of this city...just look around. "Mr. hotdog vendor,
please move."
Hotcakes: Does he not clean his windows? Vacuum his floors? If it were my store, I'd keep the sidewalk clean enought to eat off of. If it's beneath you to keep our walks clean, you can hire someone to do it for you. Come on people, get with it!
The debate is not about the quality of art; it is about basic good manners. Just as you would complain about the neighbor's dog pooing on your lawn; so goes this complaint.
The Hot Dog Guy is a bad neighbor. Did Hot Dog Man speak with Mr. DeLind before parking his dog cart at that corner? Did he apologize or even recognize the substance of the DeLind Gallery complaint? It doesn't seem to be so. This situation could be so easily remedied. I'm sure that Hot Dog Man could find a location within fifty feet from the DeLind window and all would be solved.
As to the garbage; again bad manners! American culture has descended into a toliet of uncivility. The concept of NASCAR rules, of bending, re-interpreting, arguing, flaunting, not to mention out and out breaking of rules/laws has become the norm. C'mon people, we know right from wrong.
The DeLind Gallery is a beacon of glorious visual delight - at the moment blighted by Hot Dog Man.
Hot Dog Man is located here, as he did his research and realised lots of people crossed the road to look more closely at the fabulaous art.
Clever tactic.
In the evening the Gallery is illuminated so as to provide further opportunities to view the art, and Hot Dog Man is using free lighting on his tawdry little stall, to attract the punters to purchase.
Hot Dog Man is also located here with the bright lights as it is less likely he will be mugged or robbed, clever.
BUT - for how long will those passers by want to view Art, with gangs of inebriated young things hanging round?
Who pays the insurance claim when someones slips on a disgarded weiner?
Mr Hot Dog Man - Please move over and let us all once again enjoy the evening delights of a Milwaukee stroll, without the whiff of onions, the prospect of vermin having an free snack.
Milwaukee has changed and improved its appeal, and the DeLind Gallery is adding pazzazz to the area. To start to dispoil the area again is to return to times of gloom and gloomier times past.
As for the Beasties - my pride and joy is to have a wee one at home, in Scotland, it has travelled with me all over the globe and been commented on by all who see it.
Think of the Beasties as Goodwill Ambassadors for Milwaukee, better to have artistic emblems than to be known as Hot Dog Heaven
BTW - Mr HDM - you look like a vagrant sitting on the window sill - sorry but move the cart please.......alas, all our comments are now making the Man famous.......will he ever go?

Is there an Ubuntu equivalent to the BSD Ports system? I realize that the Linux and Ubuntu culture tends to install new software from binaries, but having used BSD ports within both BSD and Mac OS X I find it very simple and elegant and the idea of compiling from source on demand, with all dependencies figured out for you, is very powerful.
Most linux distributions, Ubuntu included, distribute packages as binaries. Unless you have a very specific need, IMO, building from source is over rated.
IMO, if you wish to compile from source, you are better off using LFSor Gentoo.
You can, of course, achieve the same thing with Ubuntu by building from source. You should avoid installing packages outside of apt as much as possible.
here is a nice overview of why (fedora wiki).
So what you would do on ubuntu is download the source code from the ubuntu repositories, make any modifications needed, build a package, and install it with apt (dpkg). Doing so is poorly supported, and as with LFS and Gentoo you will need to do a bit of reading.
The documentation is a bit scattered.
Enable the source repositories
You need to enable the source repositories to download the source code.
See Ubuntu wiki repositories for details.
apt-build will build from source and is probably the best way of achieving what you want on Ubuntu or Debian (or Mint ...)
Configure your options
You probably want to use -jx where x = number of CPU +1
To prevent your compiled packages / libs from being over written, put these options in
see man apt-build
apt-get will download the source and install dependencies (binaries)
You can then build and package with any number of tools.
The page on compiling a kernel has more details and alternate options (fakeroot,
That should get you started ;)

Engineers and designers are highly skilled individuals. Forcing them to enter design changes using tables, forms and spreadsheets is unproductive and uneconomical, and it increases the likelihood of human error—this is the way that most instrumentation software systems currently work. For too long, software vendors have denied engineers and designers the simple practicality of a graphical visual engineering interface with "drag and drop" capability and inbuilt intelligence, ensuring changes are automatically replicated into all the associated data and databases.

6 Random Coincidences That Created The Modern World
#3. The Spur of the Moment Land Deal that Created an Empire
As you can see, it's easy to take great men and accomplishments for granted. After all, Napoleon was a brilliant general, so it's easy to assume that no matter what else happened, he would have taken power in France, and got closer to conquering the world than anyone else in modern history.
The Ridiculous Coincidence
The thing was, Napoleon wasn't born in France, but on the French island of Corsica, in 1769. And as recently as the year before that, Corsica wasn't French.
Pictured: Bonaparte House, and the only reason Corsica is important.
Before the day the Corsican landscape presumably tore apart to deliver baby Napoleon from the earth in a storm of fire, the island was ruled by Genoa. More specifically, it was ruled by whichever filthy rich bearded Genoese banker bribed the duke enough to be granted governorship. Unfortunately, the island was constantly rebelling or being conquered by random Turks.
Finally, after five centuries of struggling, Genoa said "fuck it" and gave up on Corsica. Honestly, it was pretty shitty, anyway. The duke sold it to some French guy.
Then that guy handed it over to the French crown, for whatever reason. Over the next several years, French soldiers were smuggled onto the island and stuffed into the citadels.
Finally, in 1768, Genoa and France signed a treaty, officially ceding the island to France.
And How Did it Change The World?
Out popped Napoleon Bonaparte a year later. Even though he was born to an Italian family, it was technically on French soil--and even then only tentatively, as Corsica was revolting again. Thus, he became a French citizen, which allowed him to join the French Army.
Fast forward a couple of decades. The French Revolution comes to Corsica, and the next thing anyone knows, some random Italian idiot from some backwater island nobody had ever heard of, is ruling France, and doing a hell of a job.
If the land deal had gotten delayed, or the treaty signed later, or any one of a thousand things had happened to delay the handover for a year, no Napoleon.
#2. The Heart Attack that Saved the Western World
You know how every comic book villain and James Bond mastermind has some convoluted plan to take over the world? Totally ridiculous, right? The entire world? Come on. Nobody can possibly hope to do that.
Or maybe real villains just don't think big enough, because it can be done. In fact, if it weren't for a well-placed heart attack, it probably would have already happened.
The Ridiculous Coincidence
Welcome to Central Europe, circa mid-13th Century. A few years ago, you got word of some powerful distant nation, led by a guy named Genghis Khan, was destroying the hated Muslims. "Great!" you said. "The enemy of my enemy is my friend! What could possibly go wrong?"
Then things started getting sketchy. You heard about this mysterious army utterly annihilating Russia. Hey, that's not right! Russia is Christian! They're Orthodox heretics, sure, but they're still Christians.
Then one day, you finally meet this friend. Except, instead of bringing you Funyuns and Mountain Dew, he's here to slaughter you and everything you hold dear.
Folks, this was the Mongol Invasion of Europe. And shitty Europe, with its clunky knights and piss-poor peasantry, could do absolutely nothing to stop it. The Mongols, led by Genghis Khan and later, his son Ogedei, defeated the armies of such greats as Hungary, Austria and the Holy Roman Empire. They utterly plundered Poland (thank God that country never suffered again), and set their sights on the next densely populated nation: Germany.
Oh, yeah. They would have totally been fine.
Then, the Mongolian leader, Ogedei Khan, died. And everyone had to go back to Mongolia.
Why? Because Mongolian cultural traditions required everyone to go back home when a new khan ascended. Everyone knew that Ogedei's son Guyuk was going to succeed him, but they all had to go back to Mongolia and ceremonially "vote" for him anyway--or vote for someone else, and probably get their face skewered.
And How Did it Change The World?
More than you might think, actually. One recent book speculates that the Mongols' destruction of the Islamic heartland, and their comparative non-destruction of Europe, was what allowed the West to become the power center it was.
After they were done piling skulls into pyramids and ripping fetuses out of pregnant women's uteri, what the Mongols basically did was connect the world. New trade routes opened up, and new contacts were made between the major centers of population.
So while China and the Middle East were getting their shit burned, Europe was gaining new contact with the East. This, in turn, motivated the Age of Exploration. Hence why the West has nukes and computers and technology today, while everyone else has goats and carriages. Thanks, Mongolia!
#1. The Meteor Shower that Gave us Christianity
The fact that there are two billion or so Christians in the world today is largely due to one guy: Constantine the Great. He's the Roman emperor who legalized Christianity, converted to Christianity himself and cleared the path for spreading the religion throughout Europe and then across the globe.
So go for it, atheists. Here's who you have to blame.
But Constantine wasn't always a Christian. In 310 A.D., not-yet-emperor-Constantine was fighting a civil war against another guy laying claim to the throne, Maxentius, who we believe made such claim based purely on the fact that his name was awesome.
After several months of fighting, Constantine and Maxentius met for a single, decisive battle. Maxentius had almost twice as many men but, as it turns out, Constantine had God on his side. A few hours before the battle, Constantine "saw with his own eyes in the heavens a trophy of the cross arising from the light of the sun, carrying the message, 'Conquer By This.'"
And he did.
The World-shattering Coincidence
Depending on how religious the person is you are talking to, the sign he saw in the sky was either a miracle or some ridiculous thing he imagined/made up later for the awesomeness. Turns out, it was apparently just a massive, flaming meteorite that just happened to be flying by at that moment.
That's right, the entire religious makeup of the modern world turned on a random hunk of space rock.
OK, that doesn't explain the words "Conquer By This" flying across the sky. It's possible here that he decided to enhance his meteor shower viewing by dropping some nice acid.
If however it turns out the meteor's trajectory was such that its flame trail did somehow spell out "Conquer By This" across the sky in the man's own language, well, we probably have to give props to the divine intervention school of thought.
And How Did it Change The World?
Constantine went on to win and become Roman Emperor. Forever altered by the events of the battle, he passed the Edict of Milan, which granted religious tolerance to everyone!
Well, not everyone.
Christianity exploded in popularity and a few decades later, was declared the sole religion of the empire. And the rest is... well, you know.

One thing that I've noticed with Canon DSLR camera is they will disable or limit autofocus when the lens is below certain aperture values, which are specified in my answer to What are the aperture limits for autofocus on Canon DSLR cameras? Note that Nikon cameras are also typically limited to f/5.6 except for models featuring the latest revision of the Multi-CAM 3500 AF system as in the D4 and D800.
As far as I am aware, Olympus and Pentax do not have these limitations, even if autofocus may be slow or unreliable beyond f/5.6. (Sony/Minolta requires at least f/6.3, with one exception for a 500mm f/8 autofocus mirror lens, and the Alpha 850 and 900 have a center AF point with high precision at f/2.8.) For example, on Pentax, 9 of the 11 points are cross-type and remain so at all apertures. The Pentax AF system has been reported to work at f/8 and beyond, though extremely slowly. Olympus Four Thirds cameras will continue to attempt to focus below f/5.6 as well. Why do Canon and Nikon choose to limit AF functionality instead of attempting to focus with reduced performance beyond the above cutoffs?
