On my server, I have PHP 5.6 to 8.1 installed and use the versions for various testing purposes.
To change the memory_limit across all versions as simply as possible instead of editing each file, I use the following command.
find /etc/php -iname 'php.ini' -exec sed -i 's/memory_limit = .*/memory_limit = 512M/g' {} \;
I needed a quick way to check activation status of Windows Servers in a domain. This is the solution I came up with using PowerShell to run the slmgr.vbs script for output. I’m not great with PowerShell, and I’m sure this can be cleaned up or made more efficient, but this ‘hack’ worked for me.
$computers = get-adcomputer -filter "OperatingSystem -Like '*Windows Server*' -and Enabled -eq 'True'" | select-object name
foreach($computer in $computers) {
write-host $computer.name
Invoke-Command { (cscript /Nologo "C:\Windows\System32\slmgr.vbs" /xpr) -join '' } -ComputerName $computer.name
}
The output will be one of the following, with variation to the edition:
Windows(R), ServerStandard edition: Windows is in Notification mode
Windows Server(R), ServerDatacenter edition: The machine is permanently activated.
To have System.IO.FileSystemWatcher LastAccess work, the system must have access logging enabled with the following command.
fsutil behavior set DisableLastAccess 0
After setting this, reboot, and you can successfully use the FileSystemWatcher to monitor LastAccess of files (sorta).
FileSystemWatcher lWatcher = new FileSystemWatcher(@"C:\windows\temp", "*.*");
lWatcher.NotifyFilter = NotifyFilters.LastAccess;
lWatcher.EnableRaisingEvents = true;
lWatcher.Changed += new FileSystemEventHandler(HandlerWatcherChanged);
lWatcher.IncludeSubdirectories = true;
}
}
static void HandlerWatcherChanged(object sender, FileSystemEventArgs e)
{
Console.WriteLine("[" + DateTime.Now.ToString() + "] ACCESS " + e.FullPath.ToString());
}
Over the last few weeks I’ve been using Python to scrape the Pennsylvania Department of Health’s Coronavirus page. Over time the page has evolved and even split into sub-pages which contain table date of cases, deaths and other statistics.
I’ve decided to put my Python script on GitHub for public consumption. Initially when I had created the script, it was used to send me alerts when the reported numbers changed as there was no set time during the day that the website was updated, so I wanted to set up a cron job to check the website and alert me of new updates.
Below you’ll find the main script. Note that the code below may be out of date, so please check my GitHub repository for the latest. The code changes almost daily as it seems Pennsylvania Dept. of Health changes the structure, or adds new data, to the webpage which throws off my code.

I’ve been trying to learn some Python and have been tinkering with the requests module. Here is how I am able to log into a webpage, such as WordPress.
import requests
url = "https://techish.net/wp-login.php"
redirect_to = "https://techish.net/wp-admin/"
with requests.Session() as session:
post = session.post(url, data={
'log': 'admin',
'pwd': 'password',
'redirect_to': redirect_to
}, allow_redirects=True)
get = session.get(redirect_to, cookies=post.cookies)
print(get.text)
