![]() The identifiers (such as database names, table names and column names) are case sensitive in some platforms but case insensitive in others (e.g., In general, identifiers are case sensitive in Unixes but case-insensitive in Windows). For clarity, I often show the keywords in uppercase (e.g., CREATE TABLE, SELECT). It is a good practice to back-quote all the identifiers in a script to distinguish the names from the reserved words (possibly in future MySQL versions). Identifiers (such as database names, table names and column names) must be back-quoted if they contain blanks and special characters or are reserved word, e.g., `date`, `order`, `desc` (reserved words), `Customer Name` (containing space). *!40101 SET SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */ ĬREATE DATABASE /*!32312 IF NOT EXISTS*/ `eastwind` /*!40100 DEFAULT CHARACTER SET latin1 */ MySQL specific codes (with version number) are often generated when you export a database via mysqldump utility. You can find the MySQL server version via show version() command. The statements will be processed by MySQL if the server's version is at least at the specified version, e.g., version 4.00.14. You could include an optional MySQL version number, e.g., /*!40014. In other words, they will be processed by MySQL but treated as comments by other databases. They are recognized by the MySQL engine, but ignored by other database engines. I strongly encourage you to use comments liberally. An end-of-line comment begins with '- ' (two dashes and a space) or #, which lasts till the end of the current line.Ĭomments are ignored by the processing engine but are important to provide explanation and documentation for the script. Hence, there is no need for the terminating ' ' (to send the command to the server for processing).Ī multi-line comment begins with /* and ends with */ (just like the C/C++/Java language).

Had they come along a few years later, things might have been quite different for this outfit hailing from Fairfax, VA, for their three albums for the Columbia label hold up to this day as shining examples of the style. ![]() Powered by Broadtime Tuneportals More Info: Artful Dodger was a band ahead of it's time, casting hard-edged hooks into a mid-'70s pond that wasn't quite ready to bite on the genre that came to be known as power pop. ![]() Power pop fans, prepare to have your minds blown! Jeremy Cargill's notes feature fresh quotes from band members Steve Cooper and Steve Brigida, plus we've dug up some rare photos from the Columbia vaults. Now, Real Gone Music is shining a long-overdue spotlight on this seminal power pop band with a 2-CD set that includes all three albums plus a couple of single versions, their COMPLETE recordings for the Columbia label, newly remastered by Maria Triana at Battery Studios in New York. Their first two records, 1975's Artful Dodger and 1976's Honor Among Thieves, combine Beatle-esque pop and driving rock in the finest Raspberries tradition (interestingly, Artful Dodger had a big following in Cleveland, the Raspberries' home town) they feature refreshingly straightforward production from Jack Douglas (Aerosmith) and/or Eddie Leonetti and some really tremendous songwriting especially on tracks like "Wayside" and "Scream." And 1977's Babes on Broadway, while showing some signs of a group frustrated with it's lack of commercial success, definitely has it's moments, particularly on the song "Can't Stop Pretending." Unfortunately, without a stylistic pigeonhole to place them in, Columbia was unable to move any copies and dropped them, which explains why Artful Dodger has been so hard to find in the digital era, with CDs of their first two albums commanding huge sums online and the third one never coming out at all.

However, I use them more as a repository for articles and images, rather than a place to actively record ideas. I have a pro account for Evernote and I use Pinterest regularly. I like the idea of a digital sketchbook but I haven’t had much luck getting one to work. I still have my sketchbooks from architecture school but most of my digital files are long gone or in a format that I can’t open using today’s software. No hunting for outlets or a decent WiFi signal.Īlso, sketchbooks will last a lot longer than most digital files. All I need is a little bit of light and a pen that works and I’m good to go. It’s not meant to be read by anyone but me.Īnother reason is they never run out of power. My sketchbook is a mix of drawings, text, to-do lists and notes. This makes them perfect for capturing loose thoughts or for working out a problem. It wouldn’t be worth much of anyone else, but to me, it was priceless.ĭespite my love of digital technology, there are a lot of good reasons why I still use a sketchbook.įor one, sketchbooks are messy and unstructured. This meant two things: one, it was in fact looking pretty nasty looking and two, it was chock full of my ideas, notes and sketches from the last few months. I’d been carrying around this sketchbook for a while and it had only a couple of blank pages left. You sure you want this thing? It looks pretty nasty. Knowing I wasn’t going to convince this guy of the merits of sketching, I clenched my teeth and patiently listened until finally, he told me they found it. He spent the next couple of minutes listing all the things he does with his iPad. Save this picture! Courtesy of ArchSmarter I’ve got a great sketching app on my iPad.

We upgraded to the Royalty package but I don't believe there was really anything special with it. Whaaa? It was good to knock a bucket list item off. Later they said i could have a refill for $5. (Remember that) we got the "medieval times" cups. ![]() ok I had an alcoholic drink and my husband had a soda. the waiter asked why I didn't eat anymore. The special extra dessert was (our anniversary 10th) an piece of sheet cake that tasted like it had been in the fridge for several days(a little dry but still sweet). if you're raised with manners this is an issue. Now, I normally, don't like anything tomato. we got half a freaking dry seasoned chicken, one potato wedge, a roll. It was our anniversary, so a special night. We paid extra for the name read out thing. I can't speak for every person but my experience is some of the players are really into it and others are are just "there". What I thought was hysterical about that situation was that Christmases were highly celebrated in Medieval castles so acknowledging the day would have actually been in keeping with the authenticity of the show. Like they could get in trouble if they were overheard. Like saying Merry Christmas to a server when we were leaving and they looked around and then whispered Merry Christmas back. The guests were friendly and wishing others a Merry Christmas but it was almost like the people working were warned not to say anything. With regards to going on Christmas day, I feel like they went out of the way to not to acknowledge that it was Christmas day. Chicken was moist and they gave to-go bags for all the leftovers. As far as the meal goes, it was better than I expected. There was no "priority seating access" and everyone had cheering banner so I'm not sure what those are supposed to mean on the website. I thought for sure that our seats would be better since we made sure to get there early and were the 3rd family to check in at the VIP window. There are 3 sections on each side of the arena and we were in a side section towards the middle. We did purchase the Royalty upgraded VIP seats but I'm not sure it was worth it since I guess almost everyone has VIP seats. The other people who spoke were fine but no one in our party could understand the queen (and we are around many Hispanics day-to-day and don't usually have issues understanding). So glad that it didn't smell like horse! The storyline of the show was a bit difficult to follow since the "queen" had such a thick Hispanic accent. The show was very good and we loved seeing the performance. ![]() Neglecting the second term in parentheses would give a distance of 5,048 kilometres (3,137 mi), a 7% error.Īpproximation Graphs of distances to the true horizon on Earth for a given height h.Horizon Blue Cross Blue Shield New Jersey Individual Exchange Products ![]() If a satellite is at a height of 2000 km, the distance to the horizon is 5,430 kilometres (3,370 mi) Where R is the radius of the Earth ( R and h must be in the same units). Ignoring the effect of atmospheric refraction, distance to the true horizon from an observer close to the Earth's surface is about d ≈ 2 h R, While similar in ways to the geometrical horizon, in this context a horizon may be considered to be a plane in space, rather than a line on a picture plane. It is the fundamental plane of the horizontal coordinate system, the locus of points that have an altitude of zero degrees. In astronomy, the horizon is the horizontal plane through the eyes of the observer. However, for someone on a 1,000 m (3,300 ft) hill looking out across the sea, the true horizon will be about a degree below a horizontal line. For observers near sea level, the difference between this geometrical horizon (which assumes a perfectly flat, infinite ground plane) and the true horizon (which assumes a spherical Earth surface) is imperceptible to the unaided eye. In many contexts, especially perspective drawing, the curvature of the Earth is disregarded and the horizon is considered the theoretical line to which points on any horizontal plane converge (when projected onto the picture plane) as their distance from the observer increases. Pilots can also retain their spatial orientation by referring to the horizon. This importance lessened with the development of the radio and the telegraph, but even today, when flying an aircraft under visual flight rules, a technique called attitude flying is used to control the aircraft, where the pilot uses the visual relationship between the aircraft's nose and the horizon to control the aircraft. ![]() Historically, the distance to the visible horizon has long been vital to survival and successful navigation, especially at sea, because it determined an observer's maximum range of vision and thus of communication, with all the obvious consequences for safety and the transmission of information that this range implied. Appearance and usage View of the ocean with two ships: one in the foreground and one to the left of it on the horizon The word horizon derives from the Greek ὁρίζων κύκλος ( horízōn kýklos) 'separating circle', where ὁρίζων is from the verb ὁρίζω ( horízō) 'to divide, to separate', which in turn derives from ὅρος ( hóros) 'boundary, landmark'. In this case, the horizon would no longer be a perfect circle, not even a plane curve such as an ellipse, especially when the observer is above the equator, as the Earth's surface can be better modeled as an oblate ellipsoid than as a sphere. When observed from very high standpoints, such as a space station, the horizon is much farther away and it encompasses a much larger area of Earth's surface. For instance, in standard atmospheric conditions, for an observer with eye level above sea level by 1.70 metres (5 ft 7 in), the horizon is at a distance of about 5 kilometres (3.1 mi). Also, the higher the observer's eyes are from sea level, the farther away the horizon is from the observer. Its radius or horizontal distance from the observer varies slightly from day to day due to atmospheric refraction, which is greatly affected by weather conditions. With respect to Earth, the center of the true horizon is below the observer and below sea level. The true horizon surrounds the observer and it is typically assumed to be a circle, drawn on the surface of a perfectly spherical model of the relevant celestial body, i.e., a small circle of the local osculating sphere. On Earth, when looking at a sea from a shore, the part of the sea closest to the horizon is called the offing. The resulting intersection of such obstructions with the sky is called the visible horizon. At many locations, this line is obscured by terrain, and on Earth it can also be obscured by life forms such as trees and/or human constructs such as buildings. The true horizon is a theoretical line, which can only be observed to any degree of accuracy when it lies along a relatively smooth surface such as that of Earth's oceans. This curve divides all viewing directions based on whether it intersects the relevant body's surface or not. The horizon is the apparent curve that separates the surface of a celestial body from its sky when viewed from the perspective of an observer on or near the surface of the relevant body. The curvature of the horizon is easily seen in this 2008 photograph, taken from a Space Shuttle at an altitude of 226 km (140 mi). For other uses, see Horizon (disambiguation). |
