github 14 day traffic stats

Since github has a page which shows 14-day stats, like https://github.com/hn-88/OpenSpace-AppImage/graphs/traffic but which is behind the login of the user, I asked Claude to create a stats page for the traffic to all my public repos. The prompt is here, 

https://github.com/hn-88/hn-88.github.io/blob/master/stats/prompt.md

and the github traffic stats page is here

https://hn-88.github.io/stats/

The "clones" number is so high for the https://github.com/hn-88/OpenSpace-AppImage/ repo because of the multiple daily build workflows.

adjusting sound volume on Mac

Since I don't have an Apple keyboard, adjusting the volume on the Mac mini was not very straightforward. An LLM's advice seemed to be a bit sarcastic when taken in the context of how easy it should be versus the method suggested - 

Adjusting the volume using the menu bar is a simple and straightforward method. Here are the steps to follow:

1. Click on the Apple logo in the top-left corner of your screen.
2. Select "System Preferences" from the drop-down menu.
3. In the System Preferences window, click on "Sound."
4. Go to the "Output" tab.
5. Drag the volume slider to adjust the volume level.

On my machine, it was "System Settings" and not Preferences. And, there seemed to be a slightly faster way, which is clicking on the "Control Centre" in the menu bar - screenshot below - the "edit controls" button allows us to drag the icon into the menu bar, too.

SSL certificates for an internal web server as backend for app

There was a query about installing SSL certificates for an internal web server, which was to be used as backend for app. Copy-pasting my reply.

Since the app needed trusted certificates, just using a self-signed certificate would be unwieldy, probably needing the installation of our own cert chain on each device or something like that. 

Also, since free SSL certificates from https://letsencrypt.org/ need updating every 60/90 days, buying a certificate may be an option with fewer hassles for this internal server with no external ip address.

https://www.nettigritty.com/sslcertificate.php

has low-cost options. Most probably the lowest cost one will work, can ask nettigritty support if you have doubts.

There are lots of step-by-step tutorials on how to install, like

https://www.geeksforgeeks.org/installation-guide/how-to-install-an-ssl-certificate-on-apache/

(Can find more with https://duckduckgo.com/?q=how+to+installed+a+purchased+ssl+certificate+on+my+apache+server+on+centos+stream&ia=web )

A week later, the reply was,

it is just a java application running with java.

NO Apache. nginix is found. so tried installing with let's encrypt website using ngnix

getting thie error... 

 Detail: DNS problem: NXDOMAIN looking up A for theinternaldomain.net - check that a DNS record exists for this domain; DNS problem: SERVFAIL looking up AAAA for theinternaldomain.net - the domain's nameservers may be malfunctioning

Hint: The Certificate Authority failed to verify the temporary nginx configuration changes made by Certbot. Ensure the listed domains point to this nginx server and that it is accessible from the internet.

My reply was,

You will probably need to buy a certificate and install it, as mentioned in the first email in this thread.

Since theinternaldomain.net is not a publicly available DNS record, certbot cannot resolve it.

If the server is a java application running on some port, say 5000, you will need to run ngnix or apache as a reverse proxy, and install the certificate for apache/ngnix.

The reverse-proxy config for apache is mentioned here, 

https://hnsws.blogspot.com/2021/01/adding-ssl-https-to-http-mp3-streams.html

(but of course, don't use certbot, purchase and install a cert instead as mentioned in the first email in this thread.)

using Blender to mask bright scenes

Using the same technique as in this previous post, but running on Blender 5 on Mac Mini, 3840x2160 video for Unseen Earth was being rendered at around 15 fps using the ProRES LT codec. Apparently Blender still doesn't have GPU accelerated output codec support, and this is one of the fastest codecs as suggested by ChatGPT. The ProRES LT can then be re-encoded as HEVC using the py-ffmpeg-warp presets. 

Some more tweaks used were:

• Multiple masks one atop another to darken extremely bright areas,
• Using Shift-D to duplicate and then K to cut the mask
• Using an adjustment layer to increase contrast for the base layer. 

Edit: April 2026 - I now see that Blender 5 has "Curves" as one of the Adjustment layer modifiers - so, we can easily clamp bright regions using a "Curves" filter. And it looks like this has been there in older Blender versions as well.

close all Finder windows on Mac

It looks like Option+Cmd+w is the keyboard shortcut to close all windows of an app. Also, Finder has this method of Option+click on the File menu, which then shows a "Close all" menu item. 

A bit clunky in my opinion. And apparently many people moving from Linux/Windows to Mac have this problem, due to selecting a large number of files and hitting "Get Info..." like I did - MacOS then proceeds to open that many info boxes instead of showing a single window with cumulative info as on Linux/Windows.

Moodle custom reports not being emailed

One of our Moodle instances had this issue being reported, that some newly created custom reports were not being emailed as scheduled. 

The issue was that notifications - including email notifications - were disabled for "Custom report builder schedules" at https://ourserver.org/admin/message.php

After enabling email notifications now for this, "Custom report builder schedules" - the issue was reportedly resolved.

DNS resolving glitch with lovable

One of our colleagues wanted a domain verified by "lovable the AI agent" - https://lovable.dev/

After setting up the verification txt record and the provided A record, he still got an error 1000 when trying to browse the website on the newly added subdomain - DNS points to prohibited IP.

Lovable suggested removing the proxy toggle on cloudflare (but that was already set to DNS-only).

So, I suggested that he maybe needs to click on some "verify domain ownership" button somewhere in "lovable" control panel if any ... 

He replied that he had initially used bigrock setup, now he "removed the domain in project settings of loveable and added again, it is now working."

google workspace storage limits

At some point of time, Google Workspace has added a feature to admin.google.com where we can set individual users' storage limits on or off, or change the value on an organizational unit basis. Our current Google workspace now has this feature. One possible catch is that the on/off setting is inherited from the base organizational unit. And it also seems to allow certain users to use 146% of their quota!
