One of the first things we try to do on a fresh Windows server install would be to download and install Chrome or Firefox, due to the extreme tiresomeness of "locked down Internet Explorer" which doesn't allow any downloads by default. A quick way to do that is via powershell, courtesy this page -
powershell -command "& { (New-Object Net.WebClient).DownloadFile('https://example.com/file.zip', 'c:\somefile.zip') }"I needed to find all files modified in the last 10 days in a directory using the Linux bash shell. One of the ways listed was using find -mtime,
find /var/the/relevant/dir -mtime -10
A drop-down list called Chapter gets updated by the following code -
| window.addEventListener('load', getChapterData); document.getElementById("board").addEventListener('change', updateChpDropdown); document.getElementById("standard").addEventListener('change', updateChpDropdown); document.getElementById("subject").addEventListener('change', updateChpDropdown); function updateChpDropdown() { if (document.getElementById("dataready").innerHTML == "Yes") { // clear the dropdown document.getElementById("chapter").innerHTML = '<option value="Choose">Chapter</option>'; var ddl = document.getElementById("chapter"); var chosenboard = document.getElementById("board").value; var chosensubject = document.getElementById("subject").value; var chosenstandard = document.getElementById("standard").value; for (var j=0; j < chapObj.length; j++ ) { if (chapObj[j]["boardname"]==chosenboard && chapObj[j]["subjectname"]==chosensubject && chapObj[j]["standardname"]==chosenstandard) { var option = document.createElement("OPTION"); option.innerHTML = chapObj[j]["chaptername"] ; option.value = chapObj[j]["chaptername"] ; ddl.appendChild(option); } } } } function getChapterData() { var xmlhttp = new XMLHttpRequest(); xmlhttp.onreadystatechange = function() { if (this.readyState == 4 && this.status == 200) { chapObj = JSON.parse(this.responseText); document.getElementById("dataready").innerHTML = "Yes"; } }; xmlhttp.open("GET", "https://script.google.com/macros/s/ID_OF_GAS_SCRIPTyL/exec",true); xmlhttp.send(); } </script> |

Changes for postgresql DB
and so on.
Google Meet offered recording to drive, and later restricted the recording to these editions of Google Workspace. So, I get lots of queries on how those without those editions can record.
One option was to stream the Google Meet on youtube live via services like streamyard. The youtube live stream is automatically recorded, and there is no hassle of saving locally and then uploading. The streamyard free plan has a limit of 20 hours a month.
If you wish to record more than that, it may be advisable to record locally either using software or a hardware screen-grabber.
One of the ways to do that would be using the free software called OBS - https://obsproject.com/
Record google meet call with OBS, https://www.youtube.com/watch?v=2ipPdxOZ27U
Some changes in settings from the above video in my notes on recording with Linux Mint on a 2010 model Macbook Pro - 30 fps was fine.
Had to "Lock X server when capturing" in the Window capture (Xcomposite) settings for the Meet video to be not black. Else, after clicking join, video becomes black.
While upgrading Moodle on one of our sites, There was a warning, with a link to https://docs.moodle.org/311/en/MySQL_full_unicode_support
The admin of the site reported,
Received an error message, "Error writing to database" on trying to add an emoji.
Though emojis were not so important, Indian language support was required.
On checking the collations, found that the db used
Default Charset = utf8 and
Default Collation = utf8_general_ci
just like another test site of ours, and that copy-pasting Indian language text was working -
So I did not change the collation to utf8mb4_unicode_ci as suggested in the Moodle documentation in the link at the beginning of this post, since this is a potentially dangerous operation, and can take a long time and can break things, so I would need to take precautions like making a backup, a rollback plan and so on.
The way to add the accessibility widget for all users, as against only one user, seems to be :
https://docs.moodle.org/311/en/Header_and_footer
I added to the HEAD section at
https://our.server.org/admin/settings.php?section=additionalhtml
and now on the widget appears fine.
Need to check it out and see if it gives something better than the default "accessibility settings" at the bottom left corner built in to Moove theme on Moodle.
