![]() ![]() Additionally, you’ll need to generate code in your application to use those relationships.Ī final complication is that people you want to share your data file with will also need to know about and act on the structures and relationships you’ve created in the data. If your application will change the data in the file, then one solution would be to read the entire file into memory, make the changes, and write the data out to another file.Īnother problem with using flat files is that you’ll need to explicitly create and maintain any relationships between parts of your data and the application program within the file syntax. Large files are still human-readable, but editing them to create data or look for problems becomes a more difficult task. The advantages of working with flat files start to diminish as the data becomes larger. Python has the built-in csv module and the powerful pandas module available, making working with CSV files a potent solution. Flat files also have the advantage of being self-contained and transferable if you want to share the data.Īlmost every programming language has tools and libraries that make working with CSV files easier. For example, Excel can import or export a CSV file to and from a spreadsheet. Many applications can export flat-file versions of the data generated by the file. Having the data in a human-readable format is helpful not only for creating the data file with a text editor but also for examining the data and looking for any inconsistencies or problems. Working with data in flat files is manageable and straightforward to implement. Usually, this means the data file needs to have some structure that the application can use to read and parse the text in the file.īelow is a CSV file named author_book_publisher.csv, used by the first example program in this tutorial: Being able to save data in a file allows you to share information from the program between users and sites where the application runs.īefore a program can read a data file, it has to be able to understand the data. ![]() Being able to read data files with Python allows you to restore an application to a useful state when you rerun it at a later time. Python excels at reading from and saving to files. The comma character delimiter indicates the boundary between data values. Each line of text represents a row of data, and each comma-separated value is a field within that row. Because they don’t have to use fixed field widths, flat files often use other structures to make it possible for a program to parse text.įor example, comma-separated value (CSV) files are lines of plain text in which the comma character separates the data elements. Flat files contain human-readable characters and are very useful for creating and reading data. Using Flat Files for Data StorageĪ flat file is a file containing data with no internal hierarchy and usually no references to external files.

Flat files are often human-readable text files-though they can also be binary data-with a structure that can be parsed by a computer program. You can achieve similar results using flat files in any number of formats, including CSV, JSON, XML, and even custom formats. Python, SQLite, and SQLAlchemy give your programs database functionality, allowing you to store data in a single file without the need for a database server.

![]() ![]() The small case/each link above the scan box in the receive operation controls whether the unit scanned and its quantity represent a quantity of packed cases or a quantity of eaches. The up arrow adds the quantity entry box. If some of your products are more fitting for scanning each unit, and others are more fitting for typing in a quantity, you can leave the RCV type qty setting as NO and then press the up arrow when receiving a unit for which you want to type the quantity. If you are entering a dimensional quantity like 12.37 pounds, then you really don't have a choice. If you are scanning in a pack of 100 identical units as eaches it is much easier to scan the barcode once and type in the quantity 100 than it is to scan each one. The quantity could be a quantity of eaches, or a dimensional quantity like weight or length. The assumed quantity is 1 for each scan, by default.Ĭhange the RCV type qty setting to YES if you want to enter a quantity for each unit scanned. The user interface will show a single entry box and will not ask you to enter quantity. If it is easiest to scan each unit, counting them one at a time, then set this setting to NO. The setting RCV type qty configures the user interface of the scanner's receive operation to show one entry box or two when you are scanning units. Typing quantity versus scanning each unit You will be able to fine tune the user interface to require the absolute minimum number of scans and button clicks, which will pay off in efficiency and reduced chance of human error.

Do the units have serial numbers? Lot IDs? Reference numbers? All three? Do you receive in cases and sell as eaches? Do you scan each unit or enter a quantity? Do your units have dimensional quantities like lengths or weights, or are they counted as eaches? If you find yourself needing to receive a shipment without a matching purchase order, you can receive it on the scanner with a temporary purchase order number and then change the order number later from the menu in the receive operation, prior to synching the scanner with the account.ĭifferent companies have markedly different requirements for scanning received units in a receive operation. If you need to stop mid-shipment, you can exit the operation on the scanner and return to it later from the main menu with Re-open operation. Then you'll scan the units to add them to the shipment. When you begin a receive operation, you will select the associated order and the sublocation into which you are receiving if you have more than one sublocation. The Receive operation on the scanner records the units you are receiving into a shipment, which matches up against a purchase order. ![]() ![]() ![]() According to the statistics gathered by Dr.Web CureIt!Ī malicious program designed to install other dangerous software on the infected computer.Ī Trojan designed to display various advertisements to Internet users.Ī Trojan that can download other malicious programs from the Internet and install them on the infected computer.Ī family of downloader programs generated by servers belonging to the LoadMoney affiliate program.

I regret not requesting the factory do this job. To ensure that the mirror or tool edges won't chip during grinding, the edges of the mirror and tool must be beveled. Getting Started - Beveling the Mirror and Tool More importantly, figuring and testing the mirror's surface to a good parabola becomes easier with longer focal ratios. Why such a long focal length? Well, I mainly enjoy looking at the planets and so a long focal length and small secondary mirror are desirable. To eliminate the need for rough grinding and save time, I had the mirror kit supplier rough grind the mirror to focal ratio of about F/8 (they also ground the back of the mirror nice and flat). I could have gone with a thinner blank or one made of plate glass to save even more money, but I read that working with such blanks can be a challenge (a thin mirror can end up being astigmatic if you are not careful during grinding, while parabolizing and testing a plate glass mirror can be difficult) and I wanted to avoid such risks even if they were minimal. By making a mirror of this size I would save hundreds of dollars compared to buying one already made. In 1999, a 14.5 inch diameter pyrex mirror blank (2.3 inches thick) was purchased as part of a kit that included a plate glass tool, numerous grits, burgundy pitch, and cerium oxide (CEO) polishing compound. So, in 1998 I decided to make a new "planetary" telescope that would be larger in size and with better quality optics. The highest power I could use before the images got really "soft" was about 130X. With such a poor wave rating, it could not resolve fine lunar or planetary details. The telescope was completed in 1983 and it worked okay for general viewing, but a spherical mirror of this size and focal length has a ~1/3 wavefront rating at best. I did not have the time or equipment to figure/test the mirror to a parabola. I ground and polished the F/8 mirror, and it came out better, but I left the mirror surface spherical. In 1982, I completed another 8 inch telescope mirror. Yet, it showed me things in the sky I had never seen before with my own eyes. ![]() The telescope itself was not any better looking. It was an 8 inch, F/10, spherical mirror and was awful looking! It had about a dozen scratches on it, two bad chips on its edge (I didn't bevel the edge enough) and a hazy unpolished zone around the mirror, starting about one inch from the edge. In 1978, I finished my first homemade telescope mirror. I've also added a short description of a homemade refracting telescope lens I made years ago, making an optical flat, and a section on my astrophotos. ![]() HOMEMADE SUN SPOTTER TELESCOPE PLUSAt the bottom of this page there are photos showing the telescope under construction, plus links to ATM sites and weather webpages to better help you determine the seeing conditions. These sources of information provided many of the techniques I used to make the telescope. HOMEMADE SUN SPOTTER TELESCOPE HOW TOI read several telescope and mirror making books and visited many amateur telescope making or "ATM" websites to learn how to build a 14.5 inch homemade telescope of this size. Since it is calculated that at 4:46 pm the sun will begin to disappear, it will reach 52 percent coverage at 5:57 pm and then, after a few minutes, the sun will completely disappear.This web page provides an overview of my large homemade telescope making project. If you are looking for the best place to enjoy this particular phenomenon, the alternative that will provide the most attractive panorama is ushuaia. On the other hand, to the north of these countries and to the south of Bolivia, Uruguay and Paraguay, it will cover between 5 and 40 percent, according to different geographical locations. In southern Chile and Argentina, the Moon will block 55 percent of the Sun. Meaning, the Sun will not be completely covered.Įclipses can be total, if the sunlight is completely obscured by the Moon or annular and partial, if only part of the Sun is obscured. The eclipse to be seen tomorrow, April 30, is partial. What will the April 30 solar eclipse look like? On the other hand, those responsible for the Osiris Astronomical Group provide as a guide the Authorized lenses should have low magnification lenses because they produce less heat and thus protect the instrument.Īlso, when telescopes or binoculars are used there is no appropriate filter for this type of event the recommendation is to ensure that sunlight passes through the lens of the device and is projected onto a smooth surface.ĪngIf in doubt, it is advisable to consult a trusted ophthalmologist. ![]() A solar eclipse will be seen on the April 30 Photo Shutterstock ![]() ![]() ![]() ![]() Ƒ Additional Information for the Triangle Mastercard: Examples of borrowing costs (rounded to the nearest cent) assuming that all charges are purchases bearing interest at the regular annual rate of 19.99%, a 30 day month, no charges made on special payment plans and no other fees, additional payments or other changes are: The Triangle Mastercard and the Triangle World Elite Mastercard do not have an annual fee.
