    1. Posted byu/jackbaty4 hours agoCard sizes .t3_xib133._2FCtq-QzlfuN-SwVMUZMM3 { --postTitle-VisitedLinkColor: #9b9b9b; --postTitleLink-VisitedLinkColor: #9b9b9b; --postBodyLink-VisitedLinkColor: #989898; } I've been on-again/off-again with paper for PKM, but one thing remains consistent each time: I don't enjoy using 4x6 index cards. I much prefer 3x5-inch cards. I realize that it's irrational, but there it is.My question is if I dive into building an antinet, will I regret using 3x5 cards? I already have hundreds of them. I have dividers, holders, and storage boxes for them. I just prefer how they _feel_, as weird as that sounds.I'd like to hear if people are using 3x5 cards successfully or if you've come to regret it.

      While it may be slightly more difficult to find larger metal/wood cases for the 4x6 or 5x8 cards, it's a minor nuisance and anyone who wants them will eventually find the right thing for them. Beyond this, choose the card size that feels right to you.

      If you don't have an idea of what you need or like, try things out for 10-20 cards and see how it works for you, your handwriting size, and general needs. People have been using 3x5, 4x6, and even larger for hundreds of years without complaining about any major issues. If Carl Linnaeus managed to be okay with 3x5, which he hand cut by the way, I suspect you'll manage too.

      Of course I won't mention to the Americans the cleverness of the A6, A5, A4 paper standards which allows you to fold the larger sizes in half to get the exact next smaller size down. Then you might get the benefit of the smaller size as well as the larger which could be folded into your collection of smaller cards, you just have to watch out for accidentally wrapping ("taco-ing") a smaller card inside of a larger one and losing it. I suppose you could hand cut your own 5" x 6" larger cards to do this if you found that you occasionally needed them.

      For the pocketbook conscious, 3x5 does have the benefit of lower cost as well as many more options and flexibility than larger sizes.

      At least commercial card sizes are now largely standardized, so you don't have deal with changing sizes the way Roland Barthes did over his lifetime.

      My personal experience and a long history of so many manuals on the topic saying "cards of the same size" indicates that you assuredly won't have fun mixing different sized slips together. I personally use 3x5" cards in a waste book sense, but my main/permanent collection is in 4x6" format. Sometimes I think I should have done 3 x 5, but it's more like jealousy than regret, particularly when it comes to the potential of a restored fine furniture card catalog. But then again...

    1. Forcertainlyagreatervarietyofcards,clippings,andsuchlikecan befiledbehind 4x6slipsthan behind3x5's.

      A benefit of 4 x 6" cards is that clippings and other items can often be more easily filed along with them as opposed to the smaller 3 x 5" cards.

    2. shall I adopt the 3x5 slip or the 4x61

      Dow indicates in 1924 that 3 x 5" and 4 x 6" are both commonly had in a range of materials the US as well as boxes or cases to keep them in. He does mention that one can also cut their own paper, indicating that this is a possibility.

    1. El factor tiempo de trabajo está también muy relacionado con la variabilidad de la presión de inyección, ya que a medida que incrementa el tiempo de operación de un motor, se incrementa el desgaste de las piezas, siendo agravado el sistema de alimentación por la variación de la calidad del combustible

      También depende del factor de cuanto uso se le ha dado a ese motor, no solo por el incremento de desgaste significa que va a bajar su calidad.

    1. Intracellular reactive oxygen species (ROS)levels in yeast cells weredetermined usingfluorescent probe 2',7'-dichlorofluorescein diacetate (DCFH-DA; Sigma# D6883). Cellular esterasesremove the diacetate groups ofthe DCFH-DAand produceDCFHwhich getsreadily oxidized to highly fluorescent product 2′,7′-dichlorofluorescein (DCF) by intracellular ROS. The fluorescent intensity of DCF corresponds to the amount ofintracellular ROSpresent in the cell.Cells grown under different environmental conditions were harvested,washed once with tissue-culture grade phosphate-buffered saline (PBS) and resuspendedin PBS to the final cell density of 1 OD. Freshly-prepared DCFH-DA (0.01M stock in DMSO) was added to the cell suspension toafinal concentration of 100 μM. Cell suspension was mixed and incubated at 30 ̊C for 30 min. After incubation,cells were washed 2-3 times with 1 ml PBS and then resuspendedin 200 μlPBS. Fluorescence intensity values wererecorded usingspectrofluorophotometer (Varioskan flash-3001, Thermo Scientific) with excitation and emission at 488and 530 nm,respectively.Fluorescenceintensityvalues obtained from probe-loaded cells were subtracted from the fluorescence intensity values obtainedfrom cells-alone samplesto remove background fluorescence

    1. Wherefore, after I have abridged the record of my father, then will I make an account of mine own life.

      The passing of info/energy/knowledge from one gene-ration to the next is often visualized and spoken of in terms of a light bridge or rainbow bridge. The process being described here as an abridgment should also be understood to signify the building and maintenance of this type of metaphysical technology for the transposing of whole bodies of information via spiritual connection between The Fathers and The Children.

    1. Stadtinfo Köln (City Info Cologne) is a research project financed by the German Federal Ministry of Research that centres around the collection of various traffic data to be distributed to diverse platforms including the Internet, portable devices such as PDAs and mobile telephones, in-car navigation systems and variable message signs throughout the city. The project was implemented over a four-year period from 1998 to October 2002 by 15 partners in co-operation with the city of Cologne at a cost of €16.1 million.

    1. Neusser Straße in the district of Nippes shows what a future SmartCity could look like, because a section of the street becomes Cologne's climatic road. There, the most important energy projects are implemented. All facets of climate protection are taken into account: from optimal building insulation and maximum heat efficiency to charging stations for electric vehicles and low-energy street lighting. Klimastraße offers innovative companies the opportunity to test their new products and services in everyday life. If possible, companies finance their projects themselves, promising projects are funded from the project budget of RheinEnergie AG. Companies also gain additional value by exchanging valuable information and innovative ideas with other companies, including at climate road events. For all the enthusiasm for innovation, of course, only technology is used that meets the very strict German safety requirements. In addition, RheinEnergie and the City of Cologne make sure that the high Cologne supply standards are adhered to. For all new projects, safety comes first - technically as well as logistically. That is why not everything changes in the climate route - but certainly much better. The following section deals in more detail with the individual projects.

      Climate Road Cologne

    1. In the framework of the project "Celsius" we investigate which method leads to the best possible results in order to increase the chances of realization. For this purpose, demonstration plants were built at three different locations in the city. In Cologne-Wahn and Cologne-Mülheim, the heat is extracted directly from the sewer using so-called gutter heat exchangers. The heat exchangers with a length of 60 and 120 meters are installed at the bottom of the canal. The heat transfer medium transports the heat from there to the heat pumps with a capacity of 150 or 200 kW in the boiler rooms of the schools supplied. In Cologne-Nippes, a total of three schools and a sports hall are supplied by sewage heat. Here, the wastewater is pumped through a newly laid, 400-meter-long bypass to the boiler room of the Edith Stein-.Realschule. There, in the largest direct evaporator in Germany (400 kW), heat is transferred directly to the heating circuit of the schools. With the three demonstration plants, an environmental relief of a total of 500 t CO2 / year is achieved. The use of wastewater heat is technically mature and well developed. Nevertheless, this form of waste heat utilization has so far been a niche existence. This is partly because it is still little known, often the necessary information is not available locally, their implementation is relatively complex and requires high investment. Further reducing these barriers is the goal of the Cologne CELSIUS project.

    1. Points of interest:

      • Uses regular expressions -- fancy pattern matching -- to scan the text of annotations

      • This one just looks for ?, the idea being a teacher is looking for students asking questions

      • Could also look for dates, currency, links, images, videos, lots of things

      • A highlight is an annotation with no text or tags.

      • This query has to perform some gymnastics to find the set of annotations that meet those two conditions

      • Gymnastics also required for the percentages

      • This pattern work for other things like: annotations vs pagenotes, public vs private, etc.

    1. Aspects of interest

      • Looks at the registered_date for users

      • Filters by domain wildcards

      • Then extrapolates to all signups, according to a 56/44 ratio established elsewhere

    1. Aspects of interest:

      • Joins annotations table and document_uri table

      • Looks for doi-related metadata

    1. Aspects of interest:

      • Finds distinct urls annotated by any CF annotator

      • Finds the average of the dates on the annotation for each url, so those sets of annotations can be arranged on a timeline

    1. Aspects of interest

      • Accesses the user_group table

      • Quotes the "group" field to distinguish it from the group keyword

      • Applies the lower string function to make matching more robust

      • Joins the user_group and group tables in order to show user counts per group

    1. Aspects of interest

      • Shows how to count different things in the same query

      • Shows how to use distinct to deduplicate

    1. Aspects of interest:

      • Uses form-based variables to parameterize the query. (

      • Formats results as a bar chart

    1. Aspects of interest:

      • Truncate date to day

      • Filter on a specified recent span of days

      • Use a complex expression to match a specified set of users

    1. Aspects of interest:

      • Uses WITH ("WITH provides a way to write auxiliary statements for use in a larger query. These statements can be thought of as defining temporary tables that exist just for one query")

      • Uses wildcard to match tlds: .edu, .ac.uk

      • Uses regular expression to match subdomains of email addresses (e.g. cornell. nyu)

      • uses array indexing to slice the regexp match

      • use || operator to join strings
