#debug

Wow.. So I was trying to #optimize some Rust code that would take six hours to run.

My goal was to get that down to 3.5 hours (something I'd achieved previously with lost code). Some tweaking got it down to 5 hours estimated runtime.

Then I thought to do:

"cargo build --release" instead of just "cargo build" for the first time.

And we're down to 3 minutes.... not 3.5 hours... 3 minutes.

Ok.. Good to know. Debug adds just a tiny bit of overhead on some code ;-).

Why people design a new #ProgrammingLanguage?

There are tons of good reasons of course. Some does that for fun or for curiosity, some for political or educational reasons, some to address shortcomings faced with existing one, either in specific use case or in general.

To me, at least at the conscious level, it's completely a political issue.

I see how programming is a new political force (so much that I actively used it to fight #BigTech in Italy) and I see how people who cannot read (aka #debug) or write (aka #programing), are doomed to becomes second class citizens in a #cybernetic society.

I don't want this to happen to my daughters, so I want to teach them how to program and debug.

BUT mainstream programming languages are weird, full of accidental complexity and with over-complicated semantics.

As a nerd who can programs in most of them, I tend to get fun in the abstractions and details of, say, a #Haskell or an homoiconic macro in a #Lisp.

But while they are fun to a person grown (and selected to fit) within such a primitive computing environment, they are inheritely excluding people who cannot spend decades to grasp their subtle intricacies.

And how you can teach such languages to kids?

Sure they can learn and understand any programming language construct way better of an average adult, but at a first glance all they will only see is glibberish!

And while some will be fascinated by such esoteric language that can be used to create games, worlds and agents that serve their will (just like I was when I was a kid), most will find that complicated and thus boring.

On the other hand a language that is explicit and with simple semantics (such as say #Oberon) will seem verbose and boring to a professional programmer.

I love the simple clarity of a #snake implementation like this https://github.com/tmartiro/voc-snake/blob/main/Snake.Mod whose complexity is almost just the complexity of the task at hand.

And while I see little improvements I could add to such language to further simplify it's syntax and semantics, when I try to do so, I end with something that is less readable than the original, despite syntax and semantics being simpler (as in less rules and no exceptions or incoherence).

It was pointed out by @anzu@items.minimals.org: while I want to make the language easy to read and simple to understand, I subconsciously try to address the issues I faced in my ~25 years as a polyglot programmer.
And apparently I can't resist such impulse, like if I cannot escape my experience.

It's sad.

It makes me think of how the phonetic alphabet was invented by people who cannot read or write but were exposed to hierogliphs, and think that creating a democratic programming language is beyond my ability because of how my mind has been blent from the existing one.

amen zwa, esq.

I grew up in Asia, so I smile and nod quietly, whenever I'm contented and happy 😄, or disconcerted and alarmed 😅, or anything in between 😏.

One of the few situations in which I frown and shake my head vigorously is when I have to #debug a pernicious, little C pointer error that threatens to derail the entire project, at the 11th hour. 😖

Such is the spice of #programming #thuglife.... 😎

PipelineC

Say I am debugging an #ethernet project on the #ice40 #fpga of pico-ice board. I want to know the contents of some registers down in my design (which destination MAC address my #hardware tried to transmit). I don't want to use manufacturer specific ILAs and don't want to hand route a bunch of debug signals to my top level for external #debug equipment I don't have.

In PipelineC just assign to a globally visible #UART debug probe wire:

Weiß irgendwer warum der #Jabber / #XMPP-#Server vom #CCC / @CCC nicht unter dessen .onion - Domain via @torproject / #Tor erreichbar ist?

Ist das nen #Bug von @monocles / #monoclesChat, @guardianproject #Orbot oder warum 404'd das?

TIL debug profiles and container filesystems. If you've ever wished you could exec into a distroless image you've probably come across the kubectl debug command. The profile switch, allows you to modify your security context whilst debugging a container. The "sysadmin" profile lets you examine the filesystem of the container being debugged. Recall that PID 1 is the entrypoint binary of the running container. If you don't have the sysadmin profile enabled, you won't be able to inspect /proc/1/root.

🏷️ #debug #kubernetes #security #til

A terminal screenshot. First, we store the name of the pod we want to debug in a variable called POD. Next, we try to kubectl exec into the pod, which will fail because it's a distroless (scratch) container. Then we try running kubectl debug using the sysadmin profile. This allows us to run the otelcol-contrib binary (to get the version) and look at files on the container under inspection.
