"DGX Spark has only half the advertised performance"(twitter.com)

I've been skeptical of NVIDIA products since playing with my Nano Jetson . The lack of various developers' success across different forums is striking. Also, the lack of actual support is striking (for example, it requires a downgraded Ubuntu host machine to receive flash updates).

My experience with Raspberry Pi products is a stark opposite. They just work.

As someone old to software but new to hardware, I'm not sure what to make of this.

I think statements like this stem from a miss-understanding mostly fueled by the DGX Spark's price and partly by Nvidia's marketing.

The DGX Spark is essentially a developer board for people that need to develop for Nvidia's newest gen hardware but cannot get the real thing because of lacking availability (not primarily price). Ignoring Nvidia's ambiguous sales message and going by the technical data it is clear the DGX Spark is not for top performance production workloads. It's a development tool.

That's a nice way to justify the DGX debacle.

Seems to be due to a misunderstanding of the expected performance of the DGX Spark: https://xcancel.com/Lasurak/status/1983178709348516238

The GPU part of it is effectively an RTX 5070, with lower bandwidth memory.

I wouldn't call that particular tweet "posturing". He's throwing out some facts that large number of followers read and many reply to. There's some legitimate give-and-take going on.

> audience that could usefully reflect on their prognostications isn't there.

This is your own bias talking.

They got used to it and there is no other place really. Other websites don't have the community and outreach.

I dislike x.com but twitter has a good niche so it sticks.

Carmack is on the record as pro-Musk.

Funny, I was got the vibe form Carmack that he's the kind of person who will crush everyone around him if he ever gets power.

Apropos, this older comment of mine https://news.ycombinator.com/item?id=37809597

He clearly had a sense of his technical skills and used that as hostile leverage within id

I find X immensely helpful for what I'm interested in: programming and machine learning. Most if not all of the people whose research & work I'm interested in are on X (Carmack included).

I think you need to deal with your own biased way of thinking before trying to judge other people.

I just created a new account on X to see what it looks like nowadays. It was shocking to see that of the top 100 trending tweets on a fresh account that doesn’t follow anyone, at least 10 were people showing off how much they hate other people.

I’m not exaggerating. It’s a platform that thrives on hate, with maybe some useful information in between.

Yeah it is genuinely terrible and getting worse. It's kinda fine if you have your own little bubble and can adapt to frequent algo changes and only use the "following" tab, but then you miss on sometimes pretty good recommendations. I used to tell people to get on there to have the latest AI news by a few good accounts, I don't anymore, I don't want to expose them to all of that hate.
spiderfarmer 10/29/2025||
You can get the latest AI news everywhere. I don't think I'm missing out not being on X.

Yes, the algorithm is horrendous. You can opt out of the algorithm. Follow people you like, use the following timeline or a third-party API, and you will never see the bad content. It's pretty simple.
spiderfarmer 10/29/2025||
I already deleted the account. I'm doing fine without X.

Elon visited Auschwitz with Ben Shapiro and declared he was "aspirationally Jewish". Trump has Jewish children and Grandchildren. Calling someone fascist and Hitler gets them murdered these days, I wish people would be more sensible.

> Elon visited Auschwitz with Ben Shapiro and declared he was "aspirationally Jewish". Trump has Jewish children and Grandchildren

Fascism and Jewishness are not inherently inexorably opposed such that being “aspirationally Jewish” (if that weren't a completely vacuous claim to start with) or having Jewish family members is counterevidence to being a fascist; Xenophobia and creating a foreign enemy are common elements of fascism, which foreign enemy it is not consistent among different particular instances of fascism.

> Calling someone fascist and Hitler gets them murdered these days, I wish people would be more sensible.

The resurgent fascism in America and its government kills far more people, far more directly, than calling people fascist could reasonably be claimed to.

justinhj 10/29/2025||
I am not sure what you mean by fascism in America or what deaths you are referring to. Seems you are okay with some political inspired murder though.

The gall of this comment...

It should be in an ignominious hall of fame.

Nazi salutes are done by Nazis. It really is that simple.

justinhj 10/30/2025|||
No, it's really not that simple. It was an ambiguous motion, explained by Musk quite clearly. Whether you believe him or not is purely subjective, but I at least offered some explanation why I do.

Exactly right, it was two: one facing the crowd, a second turned around to face Trump.
