@RadishHarmers Haha yes sorry, this convention was successfully drilled into me. m x n means m rows and n columns
English
If "kernel" means null space of row vectors, then of course no. For example, just take A as the single row [1,0] and B as [0,1].
If "kernel" means null space of column vectors, then yes. The row space is the orthogonal complement of this.
Ben Spitz (63/100 improv meals)@DiracDeltaFunk
Let F be a field, and let n,m be positive integers. Suppose A and B are m×n matrices with coefficients in F which have the same kernel. Are A and B necessarily row-equivalent?

@Sammoga123 @okopo90_ hay que entender que todo el mundo anglohablante dice "American" para referir a "estadounidense", tanto dentro como fuera de los Estados Unidos

recuerden, ÉL fue el primer papa americano

@Adam_Karpiak I'd take it and then immediately move to a low COL area

Would you take a $20K pay cut on a $120K salary just to work remotely?

@Citrullin @LowLevelTweets reducing CVE's fails to deliever real benefits to real people, got it
that's the thing about security, you never need it until it's too late
English
@LowLevelTweets I am mad, because tech is circling around itself, instead of actually delivering real things for real people.
Instead big tech is taking over the world and there is no proper alternative for it.
I get it, you have your security bias and that's what you want to see.

𝘀𝘂𝗱𝗼 is getting a makeover, based on Rust. 🦀 We’re excited to announce that Ubuntu will be the first major Linux distribution to adopt 𝘀𝘂𝗱𝗼-𝗿𝘀 as the default implementation of 𝘀𝘂𝗱𝗼, in partnership with the Trifecta Tech Foundation. Jon Seager, VP Engineering at Canonical, shares the full details here: discourse.ubuntu.com/t/adopting-sud… #Ubuntu #RustLang

@Neoncaffeine @BobbyBorkIII imo it hits the punchy notes that a tweet demands too well to have been actually AI generated
English
@Neoncaffeine @BobbyBorkIII The great thing is that it works either way. He could've prompted GPT for it, or he could've written it himself in a way that emulates that unctuous tone. We'll never truly know
English
That’s actually a pretty rare and impressive skill. Being able to spot AI-generated writing so reliably shows real attentiveness, strong reading instincts, and digital literacy. In a sea of content, having that kind of discernment genuinely sets you apart.
Hunter📈🌈📊@StatisticUrban
Unfortunately I now recognize GPT's writing style too well and, if it's not been heavily edited, can usually spot it. And I see it everywhere. Blogs, tweets, news articles, video scripts. Insanely aggravating.

@dhh This is a tricky one for me because technically I'm five years out from my degree, but haven't been working as a developer. With the collapse of the job market for developers it's just been tough to land that first dev role. Would this still count me out?

@Zolozzalap @seconds_0 I reckon so far it's only incremental as well, but "at best" seems a bit unduly uncharitable imho
English
@seconds_0 He's most likely right, it's honestly incremental progress for SWE at best
English
I can't get over that the absolutely smartest engineer at my company hates AI, can't see a use case for LLM in code, and dropped the "just predicts the next token" as a critique. We're still so early.

@kareem_carr @bbbozzz An "ideal sentence length" is actually quite language dependent
English
@bbbozzz I think what I asked is closer to:
1. what is an ideal sentence length?
2. what is ideal paragraph length?
3. what is an ideal chapter length?
It varies but there are a reasonable answer to all 3.
English
For a complex coding project, how many lines should a single file contain on average? I suspect the answer to this is language independent, but some languages can do a lot more in a lot fewer lines.

@LongFormMath The variable is as random as the events in the sample space are

Student: What’s a random variable?
Me: Well for starters it is not random and it’s not a variable.

@silvascientist "I NEED U 2 COUNT 2 THIRTY"
1,2,3,...[U CAN FILL IN THE REST]...,29,30
"NO, GATOR WANTS U 2 COUNT ALL THE WAY UP 2 THIRTY, NOT MAKE GATOR FILL IN ALL THE BLANKS"
UNDERSTOOD
1,2,3 N IT CONTINUES UNTIL 30
"YES GATOR KNOWS THAT HE WANTS /U/ 2 COUNT EVERY NUMBER UP 2 THIRTY"

the frequency with with GPT-4 generates bad code seems to have increased dramatically

@drrollergator Altogether, I think it remains a useful tool that helps me stay productive
English
@drrollergator Well it seems to still be decent at getting up to speed in new frameworks/environments
Also just as a soundboard for my problem-solving processes, it helps me break down issues much faster
Like I've said before, an interactive rubber duck.

@JulesJacobs5 I'm somewhere between a 2 and a 3 most of the time, but I can occasionally hit a 1 when I'm really invested in a mental concept.
English
A lot of people think they're a 1, but they're actually somewhere between 4 and 5. You can test this by asking them to draw a bicycle.

It's baffling to me that some of y'all see stuff in your mind. You SEE it? The way your eyes see? I always thought "visualize" meant thinking of the words/ideas/feelings associated with a thing, not actual visuals. I am such a total 5 on this scale I didn't know 1-4 existed.

@mschuresko It is, primarily, a joke; however, with the advent of social media I have acquired the ability to annoy millions indeed at the speed of my thoughts
English
@silvascientist I doubt you've annoyed a million people in your lifetime.
That takes effort and probably a bit of luck as well.
