If you’d like to learn more about character encoding, ASCII, and unicode characters, check out this article. ASCII characters can be useful for web developers, like if you need to manually insert whitespace or a special character into your HTML. If you look at the tables above, you’ll see that every ASCII character has an HTML entity number, and some also have an HTML entity name. Each HTML entity number and name starts with an ampersand (&) and ends with a semicolon (;). You can use these anywhere in your HTML to reliably render that character, no matter what the a person’s browser language is set to. In general, it’s recommended to use the HTML entity name whenever possible – they’re easier to remember, and are self-descriptive for any other developers that read your code. Here are some of the more common ASCII characters you’ll use in HTML, along with some examples. There are times when you’ll want to add a space, but want to keep other words or characters together, even if there’s a limited amount of horizontal space. Sure, it looks like there’s a normal space between the colon and the “l” in “listening”, but the character makes it so that the line will never break there. HTML, that’s not always an option. You might only have access to the HTML code, or just want to keep things simple.
I’ve been playing around with the Python library Luigi which is used to build pipelines of batch jobs and I struggled to find an example of an ExternalProgramTask so this is my attempt at filling that void. We define a few parameters at the top of the class which will be passed in when this task is executed. The most interesting lines of the run function are the last couple where we write the JSON to a file. Now we need to create a task to convert that JSON file into CSV format. The jq command line tool does this job well so we’ll use that. I wanted to call jq directly from the Python code but I couldn’t figure out how to do it so putting that code in a shell script is my workaround. Meet others in London interested in NoSQL, MySQL, and Open Source Databases. Enterprise Search London is a meetup for anyone interested in building search and discovery experiences – from intranet search and site search, to advanced discovery applications and beyond. Disclaimer: This meetup is NOT about SEO or search engine marketing. Full marks for vision and execution. Sweet! And what if we run it again? As expected nothing happens since our dependencies are already satisfied and we have our first Luigi pipeline up and running. I’m currently working on short form content at ClickHouse. I publish short 5 minute videos showing how to solve data problems on YouTube @LearnDataWithMark. I previously worked on graph analytics at Neo4j, where I also co-authored the O’Reilly Graph Algorithms Book with Amy Hodler.
When you first register for sales tax, the state’s tax authorities assign you a filing frequency. The frequencies are either monthly, quarterly, or annually – and sometimes a combination of these. This usually depends on the income or sales volume of your business, with high-grossing businesses filing more often and small businesses filing once per year. Due dates for each filing period are set by the local authorities. You should always double check in the states where you’re registered, to see the tax deadlines for the year ahead. Then you’re sure to have enough time to prepare your sales tax return with accurate information, then also file your sales tax return on time. What happens if I don’t collect sales tax? You still have to pay the tax that’s due on your sales, even if you didn’t collect it from your customers at the point of sale. That means paying out of pocket. In addition, there could potentially be penalties or fines for failing to collect the tax properly. With a tax automation tool like Quaderno, sales tax is collected for you automatically on every sale. You never have to worry about calculating tax correctly or keeping the right records. We’ll track your tax liabilities and give you clear reports for filing season. See what it’s like with a free trial!
There are 5 main formats in which to store images. Why would you choose one over another, and what are the differences? TIFF stands for Tagged Image File Format. TIFF images create very large file sizes. TIFF images are uncompressed and thus contain a lot of detailed image data (which is why the files are so big) TIFFs are also extremely flexible in terms of color (they can be grayscale, or CMYK for print, or RGB for web) and content (layers, image tags). TIFF is the most common file type used in photo software (such as Photoshop), as well as page layout software (such as Quark and InDesign), again because a TIFF contains a lot of image data. JPEG stands for Joint Photographic Experts Group, which created this standard for this type of image formatting. JPEG files are images that have been compressed to store a lot of information in a small-size file. Most digital cameras store photos in JPEG format, because then you can take more photos on one camera card than you can with other formats.
