arch Reviewing your photographs from Older Archives By niels-henriksen.blogspot.com Published On :: Fri, 11 Nov 2011 17:35:00 +0000 Sometimes its just plain fun to go through your archive of older photos. Now with a distant memory of the scenes and events your photographs may appear better than previous scans. This is in part due to that at the time there are too many good photos and those not with the highest rating but still with merit tend to get drowned out. This image was taken at one of the great Buddhas in Kamakura Japan. The hawk like bird may seem small but this Buddha is very large. Without the bird it would be hard to understand the scale of this image. It could be in anyone’s home garden. Besides scale the bird helps to give height to statue as there is the appearance that the head is up high where birds soar. The next image with people in it does convey the scale of the Buddha. In theses type of metal statues the green colors are soft and muted and it is easy for green foliage to overpower the scene. That is why I have mute the greens in the background to give the Buddha statue more visual punch. The Great Buddha of Kamakura (Kamakura Daibutsu) is a bronze statue of Amida Buddha, which stands on the grounds of Kotokuin Temple. It's the second tallest bronze Buddha statue in Japan, at a height of 13.35 meters, surpassed only by the statue in Nara's Todaiji Temple. The statue was originally built in 1252 and located inside a large temple hall. The temple buildings were destroyed many times by typhoons and a tidal wave in the 14th and 15th centuries. So, since 1495, the Buddha has been standing in the open ground. Do take the time to review your collection as there may be hidden gold or at least fond memories of places you've been.

arch Architectural signage By www.designworkplan.com Published On :: 2018-05-05T00:00:00Z This article is a show case of the relationship between architecture and graphic design. In fact, surprisingly few architects use typographical elements in their design. For this overview of projects that do make good use of lettering, I’ve probably browsed through more than thousand Architectural Designs. Below you’ll find ten buildings on integrated architectural lettering and signage I can only guess about the reason why architects make so little use of typhographical elements on their buildings. The main reason will be that the building design doesn’t need it. Most buildings can make their function clear without the use of signage on the façade. As you will find on the buildings listed below, architects used the signage to show the name of the building to the world; there is no building to be found with its function printed on it. The function is supposed to be clear. A famous architect once stated: ‘form follows function’. That’s why you know what the particular function of a building is. Architects follow their mantra. Café de Unie (The Union), Rotterdam, The Netherlands One of the first uses of typographic lettering in architecture is the façade of the café ‘De Unie’. This building was completed in 1925, and has the looks of a Mondriaan painting. From the outside the building looks very much like the front cover of the design magazine ‘De Stijl’ (The Style). This similarity is no coincidence; the architect was a member of the Style movement. Members from various disciplines, like architects, graphic designers and interior designers had a strong influence on each other. You can find this building near Rotterdam central station. It was destroyed during the second world war and has been rebuild in 1985, 500 meters from its original place.Bauhaus, Dessau, Germany At art school, everyone learns about Walter Gropius and his Bauhaus movement. The Bauhaus has been very influential in architecture and other disciplines of art. This modernist building was build in 1926 and has a beautiful lettering on its front façade. Seattle Art Museum, U.S.A. In 1991, Pritzker Prize winner Robert Venturi designed the Seattle art museum. To make sure no other use will ever be made of the building, ‘Seattle Art Museum’ has been carved into the front façade.Minnaert building The Minnaert building on the campus of Utrecht University has been named after the Belgian astronomer Marcel Minnaert. The architectural firm Neutelings Rietdijk has made very original use of huge letters to give the building its name. The columns that carry the upper levels are integrated within the letters. Terror Háza múzeum / House of Terror museum House of Terror is a museum located at Andrássy út 60 in Budapest, Hungary. Designed by architects János Sándor and Kálmán Újszászy. The reconstruction turned the exterior of the building into somewhat of a monument; the black exterior structure (consisting of the decorative entablature, the blade walls, and the granite sidewalk) provides a frame for the museum, making it stand out in sharp contrast to the other buildings on Andrássy Avenue. Wikipedia.City Museum Melbourne, Australia Designed by Garry Emery, Mark Janetzki and Ben Kluger for the City Museum Melbourne. This large folded monumental sign draws the attention to the museum and gives direction to the entrance. Eureka Tower Carpark Also designed by the Emery Studio Melbourne, big painted letters on the walls and floor, looking directly the letters are distored but standing in a right position the letters can be read perfectly. Fabulously done artwork by Axel Peemoeller.LAX One of the large LAX signs that greet visitors to Los Angeles International Airport. This sign is at the Century Boulevard entrance to the airport. Art school made me do this A fun project by Rutger de vries (Perongeluk) who used this old building to express his design ideas. It was doomed to demolition, the former nursing home in Utrecht (The Netherlands). After the elderly residents had been relocated, it had served as a student residence for another six years, but now it stood empty. Rutger de Vries says: “My work is transitory in nature; in fact I prefer to present it in places that have almost ceased to exist, where it can contrast with the setting“Library of Alexandria, Egypt Snøhetta is a Norwegian architectural firm with a very beautiful website. The buildings they design are fine too. Take for example the library in Alexandria, a huge cylinder covered with concrete plating. On those plates you can see all kinds of typographical elements in non western languages, mostly hieroglyphs.

arch Handling Spelling Mistakes with Postgres Full Text Search By www.viget.com Published On :: Tue, 25 Jun 2024 12:37:00 -0400 Background # Postgres Full Text Search (FTS) is a great way to implement site search on a website running Postgres already, without requiring additional infrastructure. On a recent engagement with a client, we were deciding between Postgres FTS and ElasticSearch. Ultimately we chose FTS because we could spin it up without having to add extra infrastructure, as we would with ElasticSearch. Since the project was written in Ruby on Rails, we were able to use the excellent PgSearch gem to implement FTS in ActiveRecord. Multisearch # As we wanted a general site search, we needed to utilize multisearch. Multisearch combines multiple ActiveRecord models into one search 'document' table that you can search against. For example, if a user searches for some search term, and the search is configured for multisearch, then every single model that we mark as multisearchable will be searched for that term at the same time. See here for more detail. Search Features # PgSearch allows for different search features, tsearch, trigram, and dmetaphone. The default is tsearch, which uses the built-in Postgres Full Text Search. This was great for our use case, since it also comes with highlighting, a feature that was required. The highlighting is from a field returned by Postgres FTS, where it returns the text around the search term for context and bolds the search terms. Spelling Mistakes # Unfortunately, tsearch does not handle misspelled words. However, as I mentioned before, PgSearch allows for other search features! And trigram is a feature that can be installed via a Postgres extension (pg_trgm) that does just that. Trigram # The idea behind trigram search is to split pieces of text into sets of three-letter segments, and compare the sets to one another If two trigram sets are similar enough, we assume there was a spelling mistake, and return the document with the correctly-spelled term. As a quick example (ignoring whitespace): Consider the word Viget. Viget would make trigrams: [vig, ige, get] Now, consider our evil twin agency, Qiget. They would make trigrams [qig, ige, get] The two trigram sets match very closely, with only one of the trigrams not being the same. Thus, if we were to compare these with pg_trgm, we could reasonably tell that anyone typing 'Qiget' must have been actually looking for 'Viget', and just misspelled it. Working Trigram into our existing solution # PgSearch allows us to use multiple search features at once, so we can use tsearch and trigram side by side. Note that we cannot just replace tsearch with trigram due to needing some features in tsearch that are exclusive to it. Here is what an example configuration might look like. PgSearch.multisearch_options = { using: { tsearch: { prefix: true, highlight: { MaxFragments: 1 } }, trigram: { only: [:content] } } } Trigram (and timelines) causing issues # While it was easy to slot Trigram into our multisearch, it caused a pretty serious performance hit. We were seeing 50x-75x slower searches with both features combined than with just tsearch. We needed to find a way to balance performance with handling misspellings At the point that handling misspellings became prioritized, the entire search feature was almost fully QA'd and about ready to go out. There wasn't much time left in the budget to find a good solution for the issue. This thread from the PgSearch repo sums it up pretty well – there were multiple other users that were/are having similar issues as we were. The top-rated comment in this thread is someone mentioning that the solution was to just use ElasticSearch ('top-rated' is doing a lot of heavy lifting. It did have the most likes...at two). We needed to find some sort of middle ground solution that we could act on quickly. Postgres Documentation saves the day # In the docs for the Trigram Postgres extension, the writers give an idea for using Trigram in conjunction with Full Text Search. The general idea is to create a separate words table that has a Trigram index on it. Something like this worked for us. Note that we added an additional step with a temporary table. This was to allow us to filter out words that included non-alphabet characters. execute <<-SQL -- Need to make a temp table so we can remove non-alphabet characters like websites CREATE TEMP TABLE temp_words AS SELECT word FROM ts_stat('SELECT to_tsvector(''simple'', content) FROM pg_search_documents'); CREATE TABLE pg_search_words ( id SERIAL PRIMARY KEY, word text ); INSERT INTO pg_search_words (word) SELECT word FROM temp_words WHERE word ~ '^[a-zA-Z]+$'; CREATE INDEX pg_words_idx ON pg_search_words USING GIN (word gin_trgm_ops); DROP TABLE temp_words; SQL This words table is therefore populated with every unique word that exists in your search content table. For us, this table was pretty large. result = ActiveRecord::Base.connection.execute("SELECT COUNT(*) FROM pg_search_words").first['count'] puts result.first['count'] # => 1118644 Keeping the words table up-to-date # As mentioned in the docs, this table is separate from your search table. Therefore, it needs to be either periodically regenerated or at least have any new words added to search content also added to this table. One way to achieve this is with a trigger, which adds all new words (still filtering out non-alphabet characters) that are inserted into the documents table to the words table create_trigger("pg_search_documents_after_insert_update_row_tr", generated: true, compatibility: 1) .on("pg_search_documents") .after(:insert, :update) do <<-SQL_ACTIONS CREATE TEMP TABLE temp_words AS SELECT word FROM ts_stat('SELECT to_tsvector(''simple'', ' || quote_literal(NEW.content) || ')'); INSERT INTO pg_search_words (word) SELECT word FROM temp_words WHERE word ~ '^[a-zA-Z]+$'; DROP TABLE temp_words; SQL_ACTIONS end Note that this does not handle records being deleted from the table – that would need to be something separate. How we used the words table # Assuming for simplicity the user's search term is a single word, if the search returns no results, we compare the search term's trigram set to the trigram index on the words table, and return the closest match. Then, we'd show the closest match in a "Did you mean {correctly-spelled word}?" that hyperlinks to a search of the correctly-spelled word Given more time, I would have liked to explore options to speed up the combined FTS and Trigram search. I'm certain we could have improved on the performance issues, but I can't say for sure that we could have gotten the search time down to a reasonable amount. A future enhancement that would be pretty simple is to automatically search for that correctly-spelled word, removing the prompt to click the link. We could also change the text to something like "Showing results for {correctly-spelled word}". Ultimately, I think with the situation at hand, we made the right call implementing Trigram this way. The search is just as fast as before, and now in the case of misspellings, a user just has to follow the link to the correctly-spelled word and they will see the results they wanted very quickly.
