I believe it’s the ANSI standard. EDIT: Actually, I think it’s the SQL-92 standard. A later version of the standard appears to optionally allow for 128 character names, but Oracle doesn’t yet support this (or has partial support for it, insofar as it allows 30 characters. Hmmm.) Search for “F391, Long identifiers” on this page… … Read more
Usingspark.sessionState.executePlan(df.queryExecution.logical).optimizedPlan.stats(spark.sessionState.conf).sizeInBytes we can get the size of actual Dataframe once its loaded into memory. Check the below code. scala> val df = spark.read.format(“orc”).load(“/tmp/srinivas/”) df: org.apache.spark.sql.DataFrame = [channelGrouping: string, clientId: string … 75 more fields] scala> import org.apache.commons.io.FileUtils import org.apache.commons.io.FileUtils scala> val bytes = spark.sessionState.executePlan(df.queryExecution.logical).optimizedPlan.stats(spark.sessionState.conf).sizeInBytes bytes: BigInt = 763275709 scala> FileUtils.byteCountToDisplaySize(bytes.toLong) res5: String = 727 MB … Read more
You have two problems. Let’s tackle them one at a time 1: the difference between python 2.5 and 2.6 on the same platform with the same font These two versions of python use different versions of tk. On my mac box, 2.5 uses tk version 8.4.19 and 2.6 uses 8.5.7. In version 8.5.2 of tk … Read more
According to: [Python 3 docs]: Numeric Types – int, float, complex: Integers have unlimited precision. Translated to code: >>> i = 10 ** 100 >>> i 10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 >>> len(str(i)) 101 >>> i.bit_length() 333 On the other hand, each C type has a fixed size (depending on platform / architecture), as clearly shown in [CPPReference]: Fundamental … Read more
I ran into the same issue just now. When using the UICollectionViewFlowLayoutDelegate method to set the cell size depending on device and device-orientation, the size would be calculated properly but subviews would not resize to fill the newly size cell. The effect was a large blank cell with small subviews that don’t fill the cell’s … Read more
You can set an individual font size for the legend by adjusting the prop keyword. plot.legend(loc=2, prop={‘size’: 6}) This takes a dictionary of keywords corresponding to matplotlib.font_manager.FontProperties properties. See the documentation for legend: Keyword arguments: prop: [ None | FontProperties | dict ] A matplotlib.font_manager.FontProperties instance. If prop is a dictionary, a new instance will … Read more
As per the documentation, these are just synonyms. size() is there to be consistent with other STL containers (like vector, map, etc.) and length() is to be consistent with most peoples’ intuitive notion of character strings. People usually talk about a word, sentence or paragraph’s length, not its size, so length() is there to make … Read more
What causes this inconsistency? The name of the array decays as an pointer to its first element. When you pass an array to an function, this decaying takes place and hence the expression passed to sizeof is a pointer thus returning pointer size. However, an array passed to sizeof always returns size of the array … Read more
As simple as: $size = (int) $_SERVER[‘CONTENT_LENGTH’]; Note that $_SERVER[‘CONTENT_LENGTH’] is only set when the HTTP request method is POST (not GET). This is the raw value of the Content-Length header, as specified in RFC 7230. In the case of file uploads, if you want to get the total size of uploaded files, you should … Read more
This actually sets two properties and is equivalent to: font-size: 100%; line-height: 120%; To quote the official documentation: The syntax of this property is based on a traditional typographical shorthand notation to set multiple properties related to fonts. As David M said in the comments, it mirrors the typesetting tradition of specifying typeface sizes as … Read more
