question:The built-in variable `hour` in pine script refers to the hour in the exchange's timezone. I would like to have a variable called `UTC_hour` to refer to UTC timezone.I am using pinescript v5.
answer:In Pine Script, there’s no built-in function to directly convert the exchange's timezone to UTC. However, we can calculate the difference ourselves and obtain a desired result. Here’s an example:```pinescript//@version=5indicator("UTC Hour", overlay = true)// Obtain the timezone offset from UTC for the selected exchangevar float timezoneOffset = timestamp("D", year(timenow), month(timenow), dayofmonth(timenow), hour(timenow)) - timenow// Calculate the UTC hourutcHour = (hour(timenow) - timezoneOffset/60/60) % 24plot(utcHour)```This script calculates the timezone offset from UTC of the selected stock exchange. Then it subtracts this from the current hour to obtain the UTC hour. The `% 24` at the end is to ensure the hour is always in the range 0-23. I've added a `plot()` function at the end to visualise the `utcHour` on the chart. This is not necessary and can be removed based on your requirements. Remember to keep timezone daylight savings offset into account, as this could affect the accuracy of the `utcHour`.
question:Our subversion repository has been moved to a new host, and we have old applications that connect to that host. We CANNOT add an alias for the new server with the old name, how can we re-connect our checked out clients to the new repository?
answer:In Subversion, you can use the "svn switch --relocate" command to change the URL of the repository you're working with. This effectively tells your client application to point to the new repository instead of the old one.Here is the general format of the command:svn switch --relocate [old URL] [new URL]For example, if your old repository was at "svn://old-server/path/to/repo" and the new one is at "svn://new-server/path/to/repo", you would run this command:svn switch --relocate svn://old-server/path/to/repo svn://new-server/path/to/repoThis command should be run at the root of your working copy. You don't need to change anything in your working copy or in the repository; the "svn switch --relocate" command takes care of everything.Note: It's an SVN best practice to do a clean up and to make sure you have no uncommitted changes in your working copy before running "svn switch --relocate", as the operation is quite drastic and can cause issues if there are conflicts or other complicating factors.Please double check that svn is installed on the client applications and that they have network access to the new server.Also, be aware that the relocate command is deprecated in SVN 1.7 and later. Instead, you can use the "svn relocate" command:svn relocate [new URL]It does essentially the same thing and it's used the same way as the old "svn switch --relocate".
question:Write a SQL query to find all entries in the "employees" table where the "salary" field is less than 50000. In addition, you should also include data from a second table, "departments", joined on the "dept_id" field. Your query should show department name along with employee details. Exclude any departments that have more than 10 employees earning less than 50000. Return the result sorted by department name in ascending order.
answer:Given the problem, the SQL query will select data from both "employees" and "departments" tables where the salary is less than 50000. JOINS are used to combine rows from two or more tables. Here, the tables will be joined using the dept_id field. An exclusion condition is given for departments with more than 10 employees earning less than 50000. This is a hypothetical solution, assuming the structure of the tables to be consistent with the requirements:```sqlSELECT e.*, d.department_nameFROM ( SELECT * FROM employees WHERE salary < 50000) AS eINNER JOIN departments AS d ON e.dept_id = d.dept_idGROUP BY d.department_nameHAVING COUNT(e.emp_id) <= 10ORDER BY d.department_name ASC;```In this query:1. The subquery retrieves all records from the "employees" table where the "salary" is less than 50000.2. The resulting selection is then joined with the "departments" table, using the "dept_id" field.3. The 'GROUP BY' clause groups the results by the department name.4. The 'HAVING' clause post-filters the groups for those that have 10 or less employees paying less than 50000.5. Finally, the 'ORDER BY' clause sorts the result in ascending order of the department name. Please replace the column names and table names with your actual column names and table names in your database. The query may need to be adjusted based on actual database schema.
question:Write a program to generate a cryptogram with a specific set of conditions. Each letter in the given sentence must be replaced by a different letter, however, the replacing element should be such that the replacing letter and original letter, both should have prime ASCII values. Additionally, the frequency count of each letter in the original sentence should remain the same even after it has been replaced in the encoded version.For example - If 'e' with ASCII value of 101 (which is a prime number) is replaced by 'g' with ASCII value of 103 (also a prime number), every occurrence of 'e' must be replaced by 'g' in the encoded sentence.Sentence = "Every cloud has a silver lining."
answer:Here is a Python solution for this problem:```pythonimport stringdef is_prime(n): if n < 2: return False for i in range(2, int(n 0.5) + 1): if n % i == 0: return False return Truedef generate_cryptogram(sentence): ascii_primes = [char for char in string.ascii_letters if is_prime(ord(char))] substitutions = {} cryptogram = '' for char in sentence: if char.isalpha(): if char not in substitutions: substitutions[char] = ascii_primes.pop(0) cryptogram += substitutions[char] else: cryptogram += char return cryptogramsentence = "Every cloud has a silver lining."print(generate_cryptogram(sentence))```This program works by first creating a list of all characters (both upper case and lower case) that have a prime ASCII value. It then goes through each character in the sentence. If the character is alphabetic and it has not already been substituted, it is substituted by the next character from the list of prime ASCII characters, and the substitution is recorded. If the character has already been substituted, the previously recorded substitution is used. Non-alphabetic characters are not substituted.
question:For some reason, when I try to install `SQL Server 2008 Express`, I get an error saying that I need to have `.Net Framework 3.5` installed first, but the thing is: I already have! So could anybody tell me if I can bypass this verification by updating a registry key or something? I have np with visual studio or any other thing... just when I try to install sql express.
answer:There could be a couple of issues causing your problem. Here's how you can try to fix it:1. Reinstall .NET Framework 3.5: Sometimes, your .NET Framework installation may get corrupted even though it looks like it's working fine. Try reinstalling it to see if your problem gets resolved. 2. Repair your existing .NET Framework 3.5 Installation: Alternatively, you can also try to repair the .NET Framework 3.5 installed in your system using the installation file.3. Windows Update: Another workaround is to ensure you have the latest Windows updates installed on your machine. Some of these updates might contain necessary prerequisites for .NET Framework or SQL Server 2008 Express.4. Check your SQL Server Installation Media: There might be an internal issue with your SQL Server 2008 Express installer. Re-download the installer from the official Microsoft website and try again.5. Registry Changes: It is not advisable to directly go ahead with Registry Changes, as incorrect modifications to the Windows Registry can severely hinder the normal operations of your system.6. Select .NET Framework 3.5 in Windows Features: You can directly enable the .NET Framework 3.5 from Windows features. To do this, Open "Control Panel" -> "Programs" -> "Turn Windows features on or off" -> Check the box ".NET Framework 3.5" -> Click "OK" and Reboot your PC.7. Use Microsoft's .NET Framework Repair Tool: Download the .NET Framework Repair Tool from Microsoft's official website and follow the instructions. This utility can automatically fix a variety of problems with .NET Framework.Always remember to back up your system and crucial files before you make any significant changes, to protect against potential loss.Please provide more detailed information regarding the error if the problem still persists. The given solutions are generic, and there may be more specific solutions depending on the error details.
question:Create a Bash script that not only changes all the filenames in a directory to lowercase, but also updates any references to these filenames in the text files themselves. The directory should be specified via command-line arguments. For an additional layer of complexity, the script should be able to send a report as a formatted HTML email detailing the changes made, to an email address provided as a command-line argument. The script should maintain a log of changes and should ensure it does not create any duplicates while renaming.Directory: Any directory specified as a command-line argument.
answer:Bash is not typically the ideal scripting environment for complex tasks like this. Sending emails is doable, but formatting those emails as HTML is not nearly as straightforward as it is in other scripting languages. Similarly, parsing & rewriting text files to replace filename string would be easier in a language with stronger text-processing capabilities. However, I'll outline a basic Bash script which could accomplish these tasks, albeit without the HTML email. For that, an integration with a language or tool more suitable for email sending might be necessary.The script changes all filenames in a directory to lowercase and replaces all occurrences of these filenames in all text files within the same directory. The script also checks if a file with the target name already exists before renaming to avoid duplicate filenames.```#!/bin/bashDIRECTORY=1cd "{DIRECTORY}"changesLog="" if [ ? -ne 0 ]; then echo "Directory not found" exit 1fifor file in *;do lowercaseFile=`echo "file" | tr '[:upper:]' '[:lower:]']` if [ "file" != "lowercaseFile" ]; then if [ ! -e "lowercaseFile" ]; then changesLog+="Changed file to lowercaseFilen" # Update references in text files for textFile in *.txt; do sed -i -- "s/file/lowercaseFile/g" "textFile" done mv -- "file" "lowercaseFile" else echo "A file with the name lowercaseFile already exists" fi fidoneecho -e changesLog# TODO: Send HTML email # Results can be emailed using command like# echo changesLog | mail -s "File Changes" [email protected]# However, this requires a working mail server on the system.# Enhancements would be needed for HTML formatting & non-local mail delivery# Such enhancements may require tools or configurations beyond simple Bash scripting ```You can run this script by passing the directory argument like this:```sh script.sh /path/to/the/directory```Please consider backup your we advise you to back up your directory before running the script.Remember, bash processing of large files could be very slow. For better performance in replacing text, Perl or AWK should be considered. Sending emails with formatting and attachments is typically done from PHP or Python, often with special libraries/packages for that purpose.
