javier_e06··on Why I don't discuss politics with friends
Friendship is more of an ideal.

javier_e06··on The Gen X Career Meltdown
I read in the article that phrase that has been popping here and there in my zeitgeist:

"exit strategy"

Like watching that game at the venue and the score is very much settled and you asked yourself:

"Where did I park?"

The revolution will not be televised.

No flying cars for us but here, takes this gadget and play Sudoku until whatever will happen, happens.

javier_e06··on Compiler Options Hardening Guide for C and C++
Last week a build broke because there was space after the Wl, some-linker-option The Warning messages can't be very challenging to decipher.

Most importantly: Are the warnings show-stoppers? Not in part of my pay grade.

There is a pragma to ignore specific warnings. This is "#pragma GCC diagnostic ignore "some-compiler-warning" which is useful when dealing with several versions of the GCC compiler.

Yes, it happens.

javier_e06··on Better Shell History Search
I lately started using copilot with eclipse I was surprise how copilot started creating complete functions for me inferring what I was trying to do. fzf could benefit of that. If I do:

make ./run_program

fzf could create a line for after I do the sam e sequence 3 times that goes:

make && ./run_program

That would be cool.

javier_e06··on Scented products cause indoor air pollution on par with car exhaust
When we had the Canada fires months ago I bought a air quality sensor that measures among other things CO2. Right now shows 548 PPM which means good.

I once lit up one of those scented candles and the sensor fire up to over 1200 PPM.

It had a wooden wick. I think that was one of the reasons.

javier_e06··on Oh Shit, Git?
Lately I've been asked to avoid merge-commits. They pollute the logs? If my push is blocked I am too far behind I create a new temp branch of master and do a "merge --squash" to it and then a "reset --hard" from temp branch back to my original branch. Heck sometimes I rather keep my changes in patches to void does darn merge CONFLICTS...specially when rebasing.
javier_e06··on I Switched to Firefox and Never Looked Back
If firefox worked with Chromecast audio I would be all set.

I have 2 of those hockey puck's audio dongles Google used to make to connect to your stereo. They only work with Chrome, SiriusXM, VLC, CalmRadio and Youtube, Chrombooks.

They don't work with Firefox.

Sad.

Maybe Mozilla should start IoT devices for Firefox.

javier_e06··on Writing as Transformation
In a lucid dream you know you are dreaming. Recently I discovered that just because I am aware that I am in a dream and my actions do not not have real consequences, the feelings connected to the actions in my dream remain real. In my dreams, and awake.

Weird.

javier_e06··on Rules for writing software tutorials
I thought that using Makefile targets was the shortest friendliest to show what a project can do. Turns out make and Makefiles can be mysterious when they fail.

Tutorials are "best-effort" and often don't dwell on the rabbit-holes they create when a poor soul runs astray of the sunny path.

Example of a good tutorial:

Python's powerline shell: https://github.com/b-ryan/powerline-shell

The README is succinct. Well put together.

javier_e06··on Trying to use Bluesky without getting burned again
Stores won't let you have cash-back from your purchase when using your debit card if you flash the card. You have to insert the card. Some cashiers don't even know that. I don't feel enlightened by that fact. Newer cars won't disengage the hand-break if parked on a slope and you don't have the seat locked in. I don't feel enlightened by that fact. The list of "rules" goes on and on and technology feels oppressive, not empowering. Maybe is artificial enlightenment?

Sorry for the rant.

javier_e06··on Commercial tea bags release microplastics, entering human cells
One solution is cut the bags with scissors and use the leaves. I remember those metal pods with a chain. Before tea bags became a thing.
javier_e06··on In Defense of Y'All
Can't agree more. I imagine the scenario of waiting for a table at a restaurant. After 10 minutes I peek at the list and someone scratched my name from it.

I can say: "You removed from the list, yet here I am waiting" I bit curt. I can say: "Y'all removed from the list, yet here I am waiting" Friendly.

Well said.

javier_e06··on Popeye and Tintin enter the public domain in 2025 along with Faulkner, Hemingway
I think the term is "presentism". The tendency to judge past and future, with the ethics and morals of today.
javier_e06··on A liar who always lies says "All my hats are green."
Mr liar.

"All my hats are green"

Is lie.

They are sombreros. Some you borrowed from me. You have no head!

javier_e06··on Everyone is capable of, and can benefit from, mathematical thinking
What is 13% of 91? I don't know. Do you? But I now 10% of 91 is 9.1 I got somewhere eh? Hey also I know that 1% of 91 is 0.91 Duh! lets triple that. 0.91 x 3 = 0.9x3 + 0.01x3 = 2.7 + 0.03 = 2.73 Now lets add 9.1.. 11.83 Weee! (Now my date is rolling her eyes and the waiter is stone faced)
javier_e06··on It's time to replace TCP in the datacenter (2023)
In your data center usually there is a collection of switches from different vendors purchased through the years. Vendor A tries to outdo vendor B with some magic sauce that promise higher bandwidth. With open standards. To avoid vendor lock-ins. The risk averse manager knows the equipment might need to be re-used or re-sold elsewhere. Want to try something new? Plus: Who is ready to debug-maintain the new fancy standard?
javier_e06··on Low-poly image generation using evolutionary algorithms in Ruby (2023)
Funny the site had the opposite effect on me. When co-mingling computer code and text I want the text resemble the code in some fashion, like header comments. Less distracting.
javier_e06··on We're Leaving Kubernetes
The article is an excellent cautionary tale. Debugging an app in a container is one thing. Debugging and app running inside a Kubernetes node is a rabbit hole that demands more hours and expertise.
javier_e06··on 200k subscribers flee 'Washington Post' after Bezos blocks Harris endorsement
I am going nuclear on Bezos. I am cancelling Amazon Prime too. I had it with these technocrats and their ego-driven quest to rule the world.
javier_e06··on Ask HN: What's the most creative 'useless' program you've ever written?
Using a a Ruby script called blinken I plugged to my makefile to blink specific patterns ont keyboard's led's to indicate that the build was "busy" led's running from left to right. Broken build: "the 3 led's scroll-lock, num-lock, caps loc flashing slowly" Build ready "the 3 led's moving to-and-fro like a Cylon" I was working on firmware for KVM's to support key-codes for all many languages. The test team was not happy with me. :( Quit messing around! They said.
javier_e06··on Let's talk about animation quality
If one looks at the YODA puppet in The Empire Strikes back, of course, moves like a puppet, but the motion is real. Jerky, emotional, human-like.

One move to The Clone Wars and the CGI moves are mechanic. Maybe the way to go about animation is not on the eye of the beholder but on careful comparison of analog vs digital renderings: Film a human running on analog and pair it pixel by pixel with the digital cgi counterpart.

javier_e06··on Congress fights to keep AM radio in cars
There was a Netflix movie last year or so about an attack on the US where people outside NYC was meandering aimlessly trying to get Internet signal in their phones while NYC appeared to be under attack I they where lost without their phones. Are people that dense? All military radios support AM radio waveform I would not purchase a vehicle without AM radio support.
javier_e06··on Do All Problems Have Technical Fixes?
I strong recommend the book The Wizard and The Prophet. We are all here enjoying over abundance of food thanks the third agricultural revolution. Technology defeated COVID. Our technology wizards keep scoring big points. The prophets claim that our wizards no only are not averting the global collapse of civilization, they are accelerating it.

Nobody needs a microwave oven but who can wait a few minutes to warm up their food?

javier_e06··on The centrality of stupidity in mathematics
I equate feeling stupid with negative re-inforcment. When I find the solution I pat myself in the back (we are programmers, nobody cares). When I can't find the solution and then is shown to me I feel bad because I my skills proved insufficient.

Yet

That sense of feeling of success and failure are so fleeting I learn to let go of both.

They are the fuel that drive my quests but I don't sleep with them. They are both volatile.

javier_e06··on Entire staff of game publisher Annapurna Interactive has reportedly resigned
I hope the staff land on their feet...

and move on.

They produced the best games out there and that, remains patent.

What happens next is corporate wrangling less to do with creativity and more to do with profits.

javier_e06··on Marketing to Engineers (2001)
Engineer mantra: Less is more. Marketing mantra: More or die.

Buy strings.

"W: “DESTROY NINETY-NINE PERCENT OF KNOWN HOUSEHOLD PESTS WITH PRE-SLICED, RUSTPROOF, EASY-TO-HANDLE, LOW CALORIE SIMPSON’S INDIVIDUAL EMPEROR STRINGETTES, FREE FROM ARTIFICIAL COLORING, AS USED IN HOSPITALS!” - Monty Python The String Sketch.

javier_e06··on The Monospace Web
TOM QVAXY I took industrial design back in the day where there was no cad. With had to space manually the letters above and crunch them to make the title pleasant to the eye. Steady hand a sense of proportion where key to pass the test with ratio rulers and Rotring mechanical pencils in hand.

My favorite font is Terminus for my code and whatever the New York Times Magazine font is for reading.

But when it comes to get the message across....Papirus.

javier_e06··on Vim Racer
sounds interesting but I don't understand what:"12 Targets (Burn Detector)" Means. What or where are the targets? I got it! Navigate to the yellow flashing square! Is fun but the numbers are relative so I can't type: :4 To go to line 4 which is the intuitive way.
javier_e06··on Galois Theory
I was put through the ringer on Louis Leithold "Calculus, with analytic, geometry". Heavy heavy book.

"Do the exercises" teacher echoed over and over. I read the chapter, I followed the examples and proceed to the first problem in the unit.

My answer was 64

I go to the end of the book and the answer was 2 1/4

I would try to reverse engineer the 2 and 1/4 to original problem... Nothing!

I would ask a friend to the problem with me.. her answer was 16.

Maybe divide by 8? that gets us 2, we are closer? Right. Why divide by 8? I don't know!

Back in the there was no Internet or Kahn Academy. It was you and the red heavy book of Calculus with the desk lamp staring at you. Silently.

javier_e06··on Show HN: If YouTube had actual channels
Love this. Good quality video and low latency. The content? Well, can't please everybody. I was looking for cartoons, any cartoon. No dice. That would be great addition.
