I stumbled upon Opening Master the other day and am quite tempted to buy the Golem subscription and use it with Scid.
Have you ever used their databases? If yes, can you share your thoughts please?
In particular:
- How is the quality of the compilation?
- Are there any annotated games in the database (like ChessBase)?
- Is it as large as they claim it to be?
- Does it receive proper regular updates?

A collection of Docker images which are otherwise not easy to find. - bahmanm/bdockerimg
If you've found yourself manually crafting complex Docker images or repeatedly installing tools, I've got something for you 😁
Check out "fusions" in bdockerimg project (https://github.com/bahmanm/bdockerimg).
---
With fusions, you merge base images into powerful composite images.
Currently there are:
- sdkman.bmakelib
- quicklisp.bmakelib
---
Let me know what other fusions would make your Docker life easier 🙏
Thanks for the pointer! Very interesting. I actually may end up doing a prototype and see how far I can get.
I've been working on a small project called bdockerimg.
It's a collection of pre-built Docker images for some less common development tools (currently bmakelib, QuickLisp, and SDKMAN).
The idea is to streamline setup, especially for CI/CD pipelines, where I found myself repeating the same Dockerfile steps a lot. Basic functionality tests are included for a bit of extra peace of mind.
---
👀 Here's the repo if you're interested: https://github.com/bahmanm/bdockerimg 🗣 And here's the the Matrix room: https://matrix.to/#/#bdockerimg:matrix.org
---
I'm curious:
- Does this seem like something you might find useful?
- Are there any specific tools you'd love to see as easy-to-use Docker images?
---
This project is still in its early stages, so any feedback or contributions are much appreciated 🙏
Do you know any chess clubs/programmes for a 5-7 year old in Vancouver/Richmond area?
I would preferably want to be able to look up the coach(es) online or attend one of their lessons before enrolling my kid.
PS: I know I may sound very picky, but I have witnessed first hand how a not great tutor in the early ages can ruin the enthusiasm for chess and change the future.
A collection of etudes for folks new to Prolog (and sometimes experienced ones) to learn the language in a practical fashion. - bahmanm/prolog-etudes
I just started learning Prolog (based on "Programming in Prolog") and in doing so I've been trying to write code as much as I can.
So far, my little collection of tiny predicates have seemed OK, to my mind.
However, I'm not sure if I'm confident about the most recent piece of Prolog code I've written: https://github.com/bahmanm/prolog-etudes/blob/main/basic-list-techniques/mapping_nested.prolog
Which is why I'm asking if I could please get a code review from the experts. Any hint/feedback is highly appreciated 🙏
Latency, aka Roundtrip Time (RTT) or Time To Load (TTL), is the time it takes for the instance to respond to an HTTP request.
---
Latency indicators have been added to the instance health breakdown dashboard, allowing you to view the latency of your favourite instance compared to itself:
- Past 3 hours compared to the past 7 days
- Past 24 hours compared to the past 30 days
- Past 24 hours compared to the past 90 days

Good question!
IMO a good way to help a FOSS maintainer is to actually use the software (esp pre-release) and report bugs instead of working around them. Besides helping the project quality, I'd find it very heart-warming to receive feedback from users; it means people out there are actually not only using the software but care enough for it to take their time, report bugs and test patches.
"Announcment"
It used to be quite common on mailing lists to categorise/tag threads by using subject prefixes such as "ANN", "HELP", "BUG" and "RESOLVED".
It's just an old habit but I feel my messages/posts lack some clarity if I don't do it 😅
The very first stable version of lemmy-synapse 🎉 What is lemmy-synapse A humble bundle of observability and monitoring for your Lemmy cluster. Read more ... What's included Docker stats dashboard ...
lemmy-synapse is a light-weight observability and monitoring stack for Lemmy servers.
---
Using Prometheus and Grafana, it allows the admins to visualise and query the stats of their instance. v1.0.0 comes out of the box with 3 detailed dashboards:
- Host stats (CPU, RAM, disk, network, ...)
- PostgreSQL stats (connections, locks, transations, queries, ...)
- Docker stats (container CPU, RAM, disk, network, OOM signals, ...)
---
It runs as Docker compose cluster alongside the Lemmy cluster and does not require any changes to it in most cases. Uninstalling lemmy-synapse is as easy as tearing down its cluster and deleting its installation directory.
---
Got questions/feedback? Pray drop a line:
As an instance admin, would you be interested in receiving alerts in case lemmy-meter detects your instance's health has deteriorated?
The alerts could be sent to any combination of
- a Matrix chat (private or channel)
- a Discord server
- an e-mail address
For example, you could receive an alert if the landing page hasn't been loading for the past 5 minutes.
---
The details of alerting levels and the conditions that'd trigger them will be ironed out later. At this stage I'd mostly would like to know if there's interest in this feature in the first place before getting to the implementation.

Follow up on https://github.com/bahmanm/lemmy-meter/issues/71
I usually capture all my development-time "automation" in Make and Ansible files. I also use makefiles to provide a consisent set of commands for the CI/CD pipelines to work w/ in case different projects use different build tools. That way CI/CD only needs to know about make build, make test, make package, ... instead of Gradle/Maven/... specific commands.
Most of the times, the makefiles are quite simple and don't need much comments. However, there are times that's not the case and hence the need to write a line of comment on particular targets and variables.
Can you provide what you mean by check the environment, and why you’d need to do that before anything else?
One recent example is a makefile (in a subproject), w/ a dozen of targets to provision machines and run Ansible playbooks. Almost all the targets need at least a few variables to be set. Additionally, I needed any fresh invocation to clean the "build" directory before starting the work.
At first, I tried capturing those variables w/ a bunch of ifeqs, shells and defines. However, I wasn't satisfied w/ the results for a couple of reasons:
- Subjectively speaking, it didn't turn out as nice and easy-to-read as I wanted it to.
- I had to replicate my (admittedly simple)
cleantarget as a shell command at the top of the file.
Then I tried capturing that in a target using bmakelib.error-if-blank and bmakelib.default-if-blank as below.
##############
.PHONY : ensure-variables
ensure-variables : bmakelib.error-if-blank( VAR1 VAR2 )
ensure-variables : bmakelib.default-if-blank( VAR3,foo )
##############
.PHONY : ansible.run-playbook1
ansible.run-playbook1 : ensure-variables cleanup-residue | $(ansible.venv)
ansible.run-playbook1 :
...
##############
.PHONY : ansible.run-playbook2
ansible.run-playbook2 : ensure-variables cleanup-residue | $(ansible.venv)
ansible.run-playbook2 :
...
##############
But this was not DRY as I had to repeat myself.
That's why I thought there may be a better way of doing this which led me to the manual and then the method I describe in the post.
running specific targets or rules unconditionally can lead to trouble later as your Makefile grows up
That is true! My concern is that when the number of targets which don't need that initialisation grows I may have to rethink my approach.
I'll keep this thread posted of how this pans out as the makefile scales.
Even though I’ve been writing GNU Makefiles for decades, I still am learning new stuff constantly, so if someone has better, different ways, I’m certainly up for studying them.
Love the attitude! I'm on the same boat. I could have just kept doing what I already knew but I thought a bit of manual reading is going to be well worth it.
That's a great starting point - and a good read anyways!
Thanks 🙏

When writing a (GNU) Makefile, there are times when you need a particular target(s) to be run before anything else.

Thanks. At least I've got a few clues to look for when auditing such code.
I just stumbled upon a collection of bash completions which can be quite handy: https://github.com/perlpunk/shell-completions
I tried mojo, cpan and pip completions in a sandbox and they worked like a charm!
The only question I've got is, has anyone ever done a security audit of the repository? Anyone has taken the time to look at the code? I could try auditing but I'm not even sure what to look for.
I feel quite wary of letting an unknown source access to my bash session and what I type.
I'm not an 1.e4 or Sicilian player but this smells like wild tactical variations early in the game.
Done ✅
Thanks for your interest 🙏
Please do drop a line in either !lemmy_meter@lemmy.ml or #lemmy-meter:matrix.org if you've got feedback/ideas for a better lemmy-meter. I'd love to hear them!
Oh and feel free to link back to lemmy-meter from Blåhaj if you'd like to, in case you'd prefer the community to know about it.
With most of the initial tasks done, I think 🌎 lemmy-meter.info is in a good place now.
I just tagged v1.0.0-beta on the repository and will be focused mainly on polishing things and fixing potential bugs in the coming days before the release of v1.0.0.
In the meantime, I'd love to know about your experience using lemmy-meter and any feedback/ideas you may have about the current version or any future versions.
Thanks in adavnce 🙏
Update 1
ttrpg.network is now on lemmy-meter 🥳 Thanks for your interest 🙏
To be precise, it's not 4 requests to the same endpoint.
lemmy-meter probes 4 endpoints each once per minute:
- The landing page
api.getPosts(limit=1)api.getComments(limit=1)api.getCommunities(limit=1)
That's b/c I've frequently experienced cases when the landing page works but some mobile APIs don't and vice versa.
Hope that makes sense.
As I said, if after some time you feel like this is too much load, reach out to me and I can easily configure lemmy-meter to probe less frequently.
Update 1
lemmy.one is added to lemmy-meter 🥳
Please do reach out if you've got feedback/suggestions/ideas for a better lemmy-meter 🙏
You can always find me and other interested folks in
Oh, sorry to hear that 😕
I think I'll just go ahead and add you folks to lemmy-meter for now. In case you want to be removed, it should take only a few minutes.
I'll keep this thread posted once things are done.
I'm interested in registering for the tournament but I've got no clue as to where to begin? Where can I find the list of teams? How can I request to join a team?
I'd appreciate any help/hint 🙏

I've been working on a simple opt-in solution, primarily for Lemmy end users like me (but also helpful for admins), to easily check the status/health of their favourite instance.
You can find the details of the implementation in ! lemmy-meter github repo.
---
❓ @admins: would you be interested in adding your instance to lemmy-meter?
You don't need to do anything except confirming - I'll handle the rest. It should only take a few minutes for your instance to show up in lemmy-meter.
Out of the box it will send only 4 HTTP GET requests per minute to your instance. However that is totally configurable if it sounds too much or too little.

Update
sh.itjust.works in now added to lemmy-meter 🥳 Thanks all.
I didn't like the capitalised names so configured xdg to use all lowercase letters. That's why ~/opt fits in pretty nicely.
You've got a point re ~/.local/opt but I personally like the idea of having the important bits right in my home dir. Here's my layout (which I'm quite used to now after all these years):
$ ls ~
bin
desktop
doc
downloads
mnt
music
opt
pictures
public
src
templates
tmp
videos
workspace

binis just a bunch of symlinks to frequently used apps fromoptsrcis where i keep clones of repos (but I don't do work insrc)workspaceis a where I do my work on git worktrees (based offsrc)
Thanks! So much for my reading skills/attention span 😂
Something that I'll definitely keep an eye on. Thanks for sharing!
