Hoy he conseguido terminar la prueba de completud de los reales (si una secuencia es Cauchy en R, converge en R) y me ha costado un huevo y parte del otro.
No sé si habría sido más fácil con Dedekind cuts, pero el tema de la diagonalización de la secuencia límite no me acababa de entrar.

Someone submitted an article about #accessibility to Hacker News. That article is about #screenReaders.
Naturally, the third comment is written by a non-screen-reader user and says that the article written by a screen reader user about screen readers is completely wrong.
Would you believe that their "experience is the opposite"? They even have the numbers to prove how wrong the author is! Their solution works at 14,000 words per minute!

it's @countrymetalhead's fault, lol, this time he shared the following on facebook, and as he said at the start, the stupid abounds. yup, all the stupid is apparently in this post. Here's what he shared. Keep in mind...these are all TRUE...
Recently, when I went to McDonald's I saw on the menu that you could have an order of 6, 9 or 12 Chicken McNuggets.
I asked for a half dozen nuggets.
'We don't have half dozen nuggets,' said the teenager at the counter.
'You don't?' I replied.
'We only have six, nine, or twelve,' was the reply.
'So I can't order a half dozen nuggets, but I can order six?'
'That's right.'
So I shook my head and ordered six McNuggets
(Unbelievable but sadly true...)
(must have been the same one I asked for sweetener and she said they didn't have any, only Splenda and sugar.)
2- I was checking out at the local Wal-Mart with just a few items and the lady behind me put her things on the belt close to mine. I picked up one of those 'dividers' that they keep by the cash register and placed it between our things so they wouldn't get mixed.
After the girl had scanned all of my items, she picked up the 'divider', looking it all over for the bar code so she could scan it. Not finding the bar code, she said to me, 'Do you know how much this is?'
I said to her 'I've changed my mind; I don't think I'll buy that today.'
She said 'OK,' and I paid her for the things and left.
She had no clue to what had just happened.
3- A woman at work was seen putting a credit card into her floppy drive and pulling it out very quickly.
When I inquired as to what she was doing, she said she was shopping on the Internet and they kept asking for a credit card number, so she was using the ATM 'thingy.'
(keep shuddering!!)
4- I recently saw a distraught young lady weeping beside her car.
'Do you need some help?' I asked. She replied, 'I knew I should have replaced the battery to this remote door unlocker. Now I can't get into my car. Do you think they (pointing to a distant convenience store) would have a battery to fit this?'
'Hmmm, I don't know. Do you have an alarm, too?' I asked.
'No, just this remote thingy,' she answered, handing it and the car keys to me. As I took the key and manually unlocked the door, I replied, 'Why don't you drive over there and check about the batteries. It's a long walk....'
PLEASE just lay down before you hurt yourself !!!
5- Several years ago, we had an Intern who was none too swift. One day she was typing and turned to a secretary and said, 'I'm almost out of typing paper.
What do I do?' 'Just use paper from the photocopier', the secretary told her. With that, the intern took her last remaining blank piece of paper, put it on the photocopier and proceeded to make five 'blank' copies… Brunette, by the way!!
6- A mother calls 911 very worried asking the dispatcher if she needs to take her kid to the emergency room, the kid had eaten ants. The dispatcher tells
her to give the kid some Benadryl and he should be fine, the mother says, 'I just gave him some ant killer......'
Dispatcher: 'Rush him in to emergency!'**
Life is tough.
It's even tougher if you're stupid!!!!
Someone had to remind me, so I'm reminding you too. Don't laugh.....it is all true...
When she was very young, my daughter looked me straight in the eye, right out of the blue, and said to me with the utter earnestness only a 3-year-old can summon:
“Be brave! Be safe! Be purple!”
I’ve been hanging on to that advice a lot lately.
I am curious...
I know I have a lot of followers who are blind, but I'd like to see how many of you are out there that this post will reach!
Including some additional demographics for interest's sake.
Please respond and boost if you don't mind!

Sharing video footage of Minneapolis-St. Paul airport, general strike picket line today 1/
Following the invasion of 3000 ICE officers,
everyday Minnesotans are pouring into #rapid #response networks and scouring their neighborhoods
—even in 20-degree weather before the sun has come up.
“I’m being tailed by a car I think is ICE,
I can make out two masked individuals through the tinted windshield,” someone says.
The call goes quiet for a few seconds.
“I’m being pulled over.”
Dispatch chimes in:
“Stay unmuted,
turn down your volume so they don’t hear the call,
everyone else please stay on mute.”
We hear banging,
then something shatters.
“ICE just smashed their window,”
our driver explains calmly,
decelerating ahead of a red light.
We are shocked,
but this is a regular occurrence.
Everyone on the call keeps their cool.
We have heard stories from rapid responders about ICE tailing them,
boxing them in,
smashing their car windows,
pepper-spraying them,
holding them at gun point,
shooting out their tires,
detaining them.
Some responders have been taken to the regional ICE headquarters,
the #Whipple building.
Others have been driven to the other side of the city
and thrown out of the vehicle, ❄️alone in the cold.
Their cars have been left running in the road.
The responders tell us all these stories in passing,
quickly returning focus to the work that is to be done.
Of course, ICE has done worse than this, too.
ICE agent Jonathan Ross shot and killed #Renee #Good as she was trying to drive away.
A week later, as ICE agents were pursuing someone,
they shot live ammunition at a house with a family in it, hitting #Julio #Sosa-#Celis in the leg.
But when you ask patrollers what they want people to know about what’s happening in their city, they barely mention the broken windows and bruises.
They describe the feeling of connection and solidarity filling the streets.
They make ❤️hearts with their hands from car to car, they blow kisses.
They make dinners for one another,
they drop off groceries for undocumented families that have been locked inside their homes for weeks.
They tell us about how, when a skirmish broke out on a busy road,
an entire café full of people stood up as one,
dropping what they were doing to run towards the sound.
We hear again and again about their deep love for the community in the Twin Cities and for their neighbors.
Every day, people who never imagined themselves fighting ICE are participating in bold combative actions

If you are in the US and have an Amazon Ring camera, disconnect it. The camera may be being used by ICE, by way of its participation in a Flock AI surveillance network.
Or sure, smash if it feels better.

Bitlocker is a Microsoft product that encrypts your laptop hard drive etc. Apparently, Microsoft exfiltrates a recovery key for your Bitlocker encryption and stores it in their cloud, they give it out to law enforcement at request. And of course, they give it out to whoever compromises their system and steals that info. Bitlocker is completely worthless trash. Do not rely on it for information security.

Ever driven the same car or used the same camera or power drill for 8-10 years and thought: "I wish all these buttons and levers were suddenly in different places and did different things"?
Yeah. Me neither.
This is a toot about operating systems.

Anyone know how often Friendica fetches RSS feeds ? Is this frequency configurable ?
I'm seeing some big delays.
Thanks.
It automatically adjusts depending on how often the source posts articles. Presumably the idea is to avoid sending frequent requests to small servers that rarely publish. This does mean that if an account only publishes once a month or so, it'll probably take a day or so before you see the article.
It used to be configurable on a per-feed basis, but looking now I think that setting went away. It can still be configured in the database I believe.
The way Friendica does RSS polling is pretty broken. You're supposed to make conditional requests so that the feed only needs to be built when it genuinely has something new, and you're supposed to respect the retry time. That way you can request much more frequently without overloading the server. But implementing that would require database schema changes.
Ah, I see, many thanks.
I just found adjustPollFrequency() in the source which adjusts the feed "rating" based on the number of recent posts.
The feed I was looking at has a rating of 8 (polling once a day) but other feeds I have lower ratings (more frequently polled). Thats consistent with what I see.
Thanks again.
TIL if you revert a commit which starts with the text "Revert" git will rename the commit to "Reapply" instead of "Revert Revert"
Please don't ask me how I learned this.
someone might also find it helpful to know there are some other magic things like "!fixup" or "!squash"
Super useful if you're working across multiple branches and are rebasing them a lot!

I previously framed the resistance against copyright as a tragedy in three parts, from anti-copyright to free software and copyleft to free culture and the so-called creative commons. But this fourth act is tragicomic. AI as Détournement.
AI is the recuperation of the anti-copyright critique.“Plagiarism is necessary. Progress implies it.” Lautréamont, 1870

in reply to Chuck Darwin • • •The situation in Minneapolis is not like anything we’ve seen before.
It’s not just an uptick in raids.
It is a full-scale military occupation, confronting you wherever you go.
You can’t drive more than a couple blocks without seeing roving bands of cars with tinted windows containing masked men in full military equipment:
helmets, balaclavas, long guns, tactical equipment, crowd control munitions.
They pull up to bus stops, leap out, grab a brown person, shove them in the car, then speed away.
They don’t check papers.
Some people have been held in detention centers for weeks before it came out that they were US citizens.
We are witnessing a #racial #pogrom.

in reply to Chuck Darwin • • •At this very moment, ICE is undergoing a transformation into a #political #police force.
Recent leaks show that
💥secret ICE programs seek to exploit every detainee to acquire information,
💥and they aim to deploy up to 2000 “intelligence” assets into communities around the country for the purpose of #spying on migrants and citizens alike.
These operations
—and the strategy of the Department of Homeland Security in general
—are not just targeting immigrants;
🆘 They are also intended to target opponents of the Trump regime.
The administration alleges threats from so-called “Antifa” and the “radical left”
to justify their authoritarian consolidation of power.
But the fact that the FBI called Renee Good a domestic terrorist
and pressured prosecutors to investigate her widow
shows what they mean by these terms.
🔥The “radical left” is a catch-all term that will be retroactively deployed to describe anyone who is randomly murdered by federal agents
—or anyone that they would like to murder.
Whenever they say “radical left,” they are saying that they intend to go on murdering people
-- the way that they murdered Renee Good,
and they intend to do so with impunity.
When the Department of Homeland Security posts a meme on its official social media account promoting “100 million deportations,”
it should be clear to all that ICE is not just targeting those who currently lack the proper immigration documents.
⛔️They have all of the hundreds of millions of people who oppose the Trump agenda in their sights.
Given a free hand, they will kidnap or murder every single one.
