Example: scss array In Sass < 3.3 you can use multidimensional lists : $ numbers : ( 3 "three" ) ( 4 "four" ) ; @each $i in $numbers { .# { nth ( $i , 2 ) } -# { nth ( $i , 1 ) } { /* CSS styles */ } } DEMO In Sass >= 3.3 we get maps : $ numbers : ( "3" : "three" , "4" : "four" ) ; @each $number , $i in $numbers { .# { $i } -# { $number } { /* CSS styles */ } } DEMO So in terms of fractions , you could just do something in this direction , so that you don't need multiple lists or maps : $ number : 6 ; $ name : ( ( "one" ) , ( "two" "halv" "halves" ) , ( "three" "third" "thirds" ) , ( "four" "quarter" "quarters" ) , ( "five" "fifth" "fifths" ) , ( "six" "sixth" "sixsths" )

Answer : Could not load file or assembly System.Runtime.CompilerServices.Unsafe It seems that you have installed System.Runtime.CompilerServices.Unsafe nuget package 4.5.3 version. And it corresponds to System.Runtime.CompilerServices.Unsafe.dll assembly version 4.0.4.1 . Suggestion 1) Please try to register System.Runtime.CompilerServices.Unsafe version 4.0.4.1 into GAC so that the system can it. Run Developer Command Prompt for VS2019 as Administrator type: cd xxxxx (the path of the the System.Runtime.CompilerServices.Unsafe 4.0.4.1) gacutil /i System.Runtime.CompilerServices.Unsafe.dll 2) If you use Net Framework projects with xxx.config file, you could use bindingRedirect. Add these in app.config file or web.config file: <configuration> <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <dependentAssembly> <assemblyIdentity name="System.Runtime.CompilerServices.Unsafe"

Answer : Those who are still looking for an alternate answer, a Clob object could be created without the need for a connection object as shown below. Clob myClob = new javax.sql.rowset.serial.SerialClob(stringData.toCharArray()); Throws warning: Clob not initialized. You need an OracleConnection to create a Clob, using the Oracle Database. OracleConnection conn; // initialize this first Clob myClob = conn.createClob(); private OracleConnection conn = null; public void setConnection( OracleConnection conn ) { this.conn = conn; } void setClob( String cookie ) throws SQLException { Clob myClob = conn.createClob(); myClob.setString( 1, cookie); } Try this : OracleConnection conn; // initialize this first CLOB clob = conn.createClob(); public Clob getClob(String data){ return clob.setString(position, data); }

Answer : The exact satisfying one-time-for-all answer I found is: Short answer: 401 Unauthorized Description: While we know first is authentication (has the user logged-in or not?) and then we will go into authorization (does he have the needed privilege or not?), but here's the key that makes us mistake: But isn’t “401 Unauthorized” about authorization, not authentication? Back when the HTTP spec (RFC 2616) was written, the two words may not have been as widely understood to be distinct. It’s clear from the description and other supporting texts that 401 is about authentication. From HTTP Status Codes 401 Unauthorized and 403 Forbidden for Authentication and Authorization (and OAuth). So maybe, if we want to rewrite the standards! focusing enough on each words, we may refer to the following table: Status Code | Old foggy naming | New clear naming | Use case +++++++++++ | ++++++++++++++++ | ++++++++++++++++ | ++++++++++++++++++++++++++++++++++ 401 | Unaut

Answer : The difference in solutions comes in the estimation of the probability that the man reports six when six has not occurred. If the man randomly chooses a number to report when he lies (which seems like a reasonable statement), then the probability he chooses 6 is 1/5. If you multiply your calculation of P(E|S2) by this, you get your teacher's solution.

Answer : The error Error on rename of ... errno: 150 - Foreign key constraint is incorrectly formed) happens because you are trying to drop a referenced primary key, even though you are disabling foreign key constraint checking with SET FOREIGN_KEY_CHECKS=0; Disabling foreign key checks would allow you to temporarily delete a row in the currency table or add an invalid currencyId in the foreign key tables, but not to drop the primary key. Changing a PRIMARY KEY which is already referenced by other tables isn't going to be simple, since you risk losing referential integrity between the tables and losing the relationship between data. In order to preserve the data, you'll need a process such as: Add a new Foreign key column ( code ) to each FK table Map the code foreign key from the previous currencyId via an update Drop the existing foreign key Drop the old currencyId foreign key column Once all FK's have been dropped, change the primary key on the
