Yes I realize all of my comments on here are dead by default. I'm quite pleased with that, and comment purely for the showdead enlightened.

Please don't vouch for my comments.

joseph_grobbles··on Intel Xeon Max 9480 Deep-Dive 64GB HBM2e Onboard Like a GPU or AI Accelerator
This is a really terribly written article. Sorry for the negativity, but it was tough to try to dig through.

For those confused by the title, Intel released a Xeon that includes 64GB of high speed RAM on the chip itself, configurable as either primary or pooled memory, or a memory subsystem caching layer.

joseph_grobbles··on Intel Xeon Max 9480 Deep-Dive 64GB HBM2e Onboard Like a GPU or AI Accelerator
It's a variation of Parkinson's Law -- we just keep expanding what we are doing to fit the hardware available to us, then claiming that nothing has changed.

CI is a fairly new thing. The idea of constantly doing all that compute work again and again was unfathomable not that long ago for most teams. We layer on and load in loads of ancillary processes, checks, lints, and so on, because we have the headroom. And then we reminisce about the days when we did a bi-monthly build on a "build box", forgetting how minimalist it actually was.

joseph_grobbles··on AI Is Catapulting Nvidia Toward the $1 Trillion Club
Google's first TPU was developed a year after Tensorflow. And for that matter, Tensorflow works fine with CUDA, was originally entirely built for CUDA, and it's super weird the way it's being referenced in here.

Tensorflow lost out to Pytorch because the former is grossly complex for the same tasks, with a mountain of dependencies, as is the norm for Google projects. Using it was such a ridiculous pain compared to Pytorch.

And anyone can use a mythical TPU right now on the Google Cloud. It isn't magical, and is kind of junky compared to an H100, for instance. I mean...Google's recent AI supercomputer offerings are built around nvidia hardware.

CUDA keeps winning because everyone else has done a horrendous job competing. AMD, for instance, had the rather horrible ROCm, and then they decided that they would gate their APIs to only their "business" offerings while nvidia was happy letting it work on almost anything.

joseph_grobbles··on Tell HN: Cancelling HP Instant Ink prevents cartridges from being used
My Brother multifunction has been without CYM inks for literally years, which was fine as I printed in only B&W. A recent system update has suddenly made it refuse to print anything, including B&W, because one or more color inks are empty, despite the black being 80% full.

Brother saw the money on the table and have decided to move towards the dark side.

joseph_grobbles··on The bill of materials for the Apple headset leaked
It's some tiny Twitter (blue) user posting some nebulous list. Seems pretty BS to me, and it's surprising HN falls for this. Okay, it actually isn't surprising.

It's actually funny how a confirmation bias works: In other posts people say "this tracks with other rumors..."...yeah, that's what people who make stuff up tend to do.

joseph_grobbles··on Planned obsolescence: Apple attacked for the “serialization” of its spare parts
Such considerations must incorporate public safety/crime considerations as well. Smartphones are often the most expensive thing we have on our person and became a huge target for thieves. Locking/bricking went a long way towards reducing this, and then limiting the value of resale parts did again.
joseph_grobbles··on Google Launches AI Supercomputer Powered by Nvidia H100 GPUs
>There's nothing in the article suggesting they've changed their strategy with TPUs in any way

Google owns and designs their own TPUs. They offer these TPUs in the cloud. I've seen many comments in here about how next-level TPUs are (despite zero evidence indicating that). Google even disclaims their TPU by saying that you shouldn't compare it with the H100 given node levels et al.

Their premiere offering is an nvidia H100 offering.

Yes, of course this is a pretty telling indication. If Google was all in on TPUs they'd be building mega TPU systems and pushing those. Instead they're pushing nvidia AI offerings.

joseph_grobbles··on Maybe you should store passwords in plaintext
Horribly cynical, and I can't imagine having that viewpoint. It's actually fascinating how the author first justifies that sort of malaise, and then does the "but of course not me" thing.

Even if someone were that self-focused, in almost any group or organization, critical security vulnerabilities and significant costs do hurt everyone in the group. You're going to be the ones having the rough time when expenses exceed value, and when major embarrassments happen. There is no insulation from it.

joseph_grobbles··on Performance excuses debunked
I once was brought into a team that fervently bought into the "hotspot" argument, blustering ahead under the notion that performance was tomorrow's problem where someone would spend a day with a profiler and it would all be fixed.

In reality their project was death by a thousand...neigh million or billions...of cuts. Poor technology choices. Poor algorithm choices. Incompetent usage (e.g. terrible LINQ usage everywhere, constantly). This was the sort of project where profiling was almost impossible because any profiling tool barfed up and gave up at every tier.

Profiling the database was an exercise in futility. Profiling the middle tier was a flame graph that was endless peaks. Profiling the front-end literally crashed the browser. I ended up having to modify Chromium source to be able to accurately get a bead on how disastrously the Angular app was built.

This is common. If performance doesn't matter to a team, it will never be something that can be easily fixed. Maybe you can throw a huge amount of money at the problem and scale up and out to a ridiculous degree for a tiny user base, but making an inefficient platform efficient is seldom easy.

joseph_grobbles··on SpaceX, Rogers to connect mobiles phones to satellites in remote Canadian areas
>This doesn't really solve a problem anyone had that fixed location Starlink and Rogers' LTE network didn't solve already

This is for locations with no connectivity, where SpaceX satellites become very low-bandwidth Rogers towers for critical situations. Your examples are not relevant.

The rest of your post is just knee-jerk opposition luddism that doesn't apply at all.

joseph_grobbles··on The Old (2018)
Would you rather they just disappear and die?

When people's dogs become older and inconvenient it is common for people to rationalize putting them "down" under the notion that it's some great benevolent act, instead of a selfish one. "Oh he couldn't jump on the bed any more so it was time to put him down". It's gross, but you nod and smile and pretend like they're being rational.

Similarly, many people want older people to disappear, and this is often masked in some benevolent "it's because I care so much" nonsense. People who want the elderly to disappear into some home somewhere where they can be sedated until they die. They can't jump up on the bed anymore, you see, so it's for the best. e.g. "I just want you to enjoy your retirement...best time of life...disappear"

A lot of older people want purpose in their life. They want to work. Particularly in Japan where there is an incredible pride and life purpose behind contributing and plying ones skills. I went down a rabbit hole of YouTube videos feature hole in the wall restaurants in Japan, and it was amazing how often it was quite elderly owners who would show up early and run the show, and it was clear they loved having it in their life.

joseph_grobbles··on Bark – Text-prompted generative audio model
I'm successfully running it on a 12GB GPU (while it downloads some 12.1GB of model data on first run, the highest GPU memory usage was ~6.5GB, settling back down to around 5GB), however the results are nothing like the samples given on the github page. Using the exact code given and in the runs I've tried the results are rather terrible.

I'm not being negative -- some of the samples are really neat on their page -- and I know there is some idiosyncrasy of my setup that is causing issues, though it is a pretty typical conda + pytorch with CUDA 11.8.

Playing with the text and waveform temp from their defaults 0.7 is yielding some semi-decent results, but it feels essentially random.

joseph_grobbles··on SpaceX Starship rocket explodes minutes after launch from Texas
27 of 33 engines fired. Performance was sub-nominal. When it was time for separation the vehicle did multiple clearly unplanned flips (during all of this the broadcast was talking about how great of a success this was, though the employees had quieted significantly knowing this was not going well). Add that Elon was looking pretty grim.

Making it clear of the tower seems like a remarkably low bar, so if that really was the measure of success, this thing is going to be ready for missions in about three decades. Like what an incredibly low accomplishment that would be.

And of course I feel overwhelmingly certain SpaceX doesn't consider this a success. The face-saving they put out for the sycophants to echo doesn't match the reality that this test proved extraordinarily little.

joseph_grobbles··on Google ordered to pay $500K to Montrealer over links calling him pedophile
Freedom applies to both parties. Your freedom to swing your fist ends where another's nose begins. Similarly, your freedom to baselessly disparage and slander has similar restrictions, because the other person has the freedom against such attacks.

Libel is very restricted in the United States as well. Indeed, the whole "section 230" argument that keeps getting revived deals specifically with this topic (paradoxically by the "freedom" party), so clearly your "freedom" isn't quite as absolute as you imagine it is.

Further, Google was ordered to restrict the content in Quebec, and the fine they are paying is a tiny fraction of the money they make in Canada, which is a country where they have offices and significant business. I see zero reason why you decided to make this American centric.

joseph_grobbles··on Why I’m using a keyboard phone in 2023
FWIW, with a bluetooth keyboard it is pretty shocking how complete the keyboard support in iOS.

I have a K480 at the office for those random times I need to respond to something on my iPhone and don't want to deal with the crippling restrictions of an onscreen keyboard, and I hugely recommend it. With the keyboard almost every norm of macOS is supported.

joseph_grobbles··on Keep stuff linkable
Here's a better approach - never, ever include a link unless it is important and cogent to the topic. Humorous or casual linking is just noise, and it can shroud actually useful links. We all can find information, so it isn't valuable linking to the definition of phrases or words, etc.

If you're referencing a study, link to the study. If you're citing a tweet, link to the tweet. Otherwise save spurious links as they add zero value and are a distraction and an unnecessary decoration making text less readable.

As an aside, I chuckled seeing the link to Atwood's "be a bigshot blogger" post where he recommended that people blog constantly about everything. For those who haven't kept track, that was a failure model. It made people basically give up on "blogs" because there was so much low value content, with people writing on a schedule rather than because they had actually interesting content. Now everyone just hopes that the rare useful post appears on a social news or media site.

joseph_grobbles··on Samsung considers moving to Bing as default search engine
Sundar is a caretaker who got credited for simple inertia: The momentum in place before he took the reigns were predestined to grow earnings for years, but suddenly Pichai gets to pretend it's all him.
joseph_grobbles··on Bob Lee, former CTO of Square, has died after being stabbed in San Francisco
Do you really believe that this public discourse occurred on a public train after a theft? Do you think they had a lively debate in the commons about how to solve crime?

I'm a bit surprised people are seriously believing this. This is someone's shower thoughts six hours later when they strawmanned some ridiculous positions to caricaturize "opponents".

I will go further and say that everything the person said seems...dubious, and are claims that are unverifiable. Like, where is this low-income "suburb" (two hours from a major center...) that has no crime? As someone who grew up in a smaller town in the rust belt, I find their claim hysterical.

joseph_grobbles··on Finland becomes the 31st member of NATO
"you can only join NATO if your membership is not a threat to your border countries"

This is, of course, complete nonsense. It is as much a fact as the oft-cited claim that NATO promised not to expand (another lie that is true only to rubes).

NATO has a requirement that you settle any ongoing border disputes before ascension: If you have a simmering feud with a neighbor country about who owns a pile of rocks, it's such an obvious flashpoint that you need to resolve it first. It has zero requirement that you don't threaten the tyrannical empire building pursuits of the neighboring madman.

Russians defending Russian aggression is something that I find just impossible to believe. Putin has sent tens of thousands of Russians into a meat grinder for a futile, ego-driven war that has zero outcome that isn't negative for Russia for decades to come. And he's going to keep grinding those bodies into corpses and you'll keep talking about deNazification or whatever nonsense you're fed.

joseph_grobbles··on $60/MWh for advanced nuclear electricity is achievable: GE Hitachi Executive
They made it up. Similarly you frequently see claims on here that nuclear came to a standstill because of all the ignorant beatnicks, when in actual reality raw capitalism is why nuclear stalled: Endless disastrously expensive projects tainted the industry into picking everything but nuclear.

Nuclear is a fantastic base load. It is, done right, clean and safe. The weird pro-nuclear cult that spreads manufactured nonsense is just noise, however.

joseph_grobbles··on Experts warn yearly checkups carry risks and do not reduce mortality
Completely anecdotal, but very infrequent checks of my blood pressure over the years would always flag high and it would always be written off as a temporary stress spike at getting it taken. Otherwise I was completely healthy and had no complaints so it was ignored.

It turns out that I had crisis levels of hypertension for years, and all of those aberrant readings were actually my normal. When I finally got it diagnosed and treated -- purely thinking it might relate to sporadic mid-sleep headaches/sicknesses [1] -- discovered that years in that state had pushed my kidneys to the cusp of kidney disease, which is something that doesn't heal.

Check your blood pressure regularly. Get an Omron unit and it even logs it into a little app. Treat it early because the damage accumulates for decades.

[1] That turned out to be a newly developed absolute intolerance for alcohol. A single beer or glass of wine with dinner would have me sick all night.

joseph_grobbles··on The FTC wants to ban tough-to-cancel subscriptions
You will never find a more wretched hive of scum and villainy than "free trial" subscription-based apps on the App Store. It is, overwhelmingly, a tool used for scams.

The pattern-

-hide promised functionality behind subscription.

-offer "free trial", often with very short trial periods.

-convert that into a big dollar subscriptions.

They know that most of the people who they ensnare are probably going through a multitude of tools trying to find a solution for some problem (and the fact the tool in question often fails to do what it promised is a feature because it encourages the user to move on quicker), and some subset will fail to cancel the "trial" before it becomes a pay service.

Consenting adults, sure, and personally I have never fallen prey to this, looking at the in-app purchases and just refusing to be baited, but it's enough of a problem that it should embarrass Apple a bit.

joseph_grobbles··on Why Apple and the Carriers Want Your Old iPhone
The refresh rate escalation is a complete jerkoff bit of tech spec nonsense. "Far better cameras" is an exaggeration, as most are marginally better. iPhones have been incredibly fast since the XR, almost five years ago.

There was a period of dramatic progress but now things have largely settled. I recently replaced a 12 Pro with a 14 Pro and it is likely nothing at all changed. There is zero impact in my life. Have the 12 Pro waiting in my drawer for my son with an XR to upgrade, but he doesn't even want the hassle of doing the transfer and then setting up the apps that don't properly migrate data.

joseph_grobbles··on Georgia’s big new nuclear reactors could be the last built in the US
Nuclear is catastrophically expensive. Nuclear stagnated not because of those "dumb protests", but because economically it turned out that they made very little sense. Projects always went massively over budget, and then had a lifespan cost multiples idealist notions.

Are they expensive because of overbearing safety requirements? Partly, sure. On the flip side, Fukushima has now cost hundreds and hundreds of billions in direct costs. If nuclear power plants didn't have a civil exemption where governments bore the potential liability of damage (which is almost infinite), they would be unbuildable.

joseph_grobbles··on Haraldur Þorleifsson sweeps person of the year awards
Bizarre to see this submission flagged. Not only is it directly related to technology, it is a fascinating discourse on what "work" is, at least in Elon Musk's incompetent vision.

That this is flagged is completely unsurprising. Musk's pathetic army of supplicants have reached the stage they hit with Trump where they are so incredibly embarrassed by his antics, yet think they've painted themselves in a corner supporting him, that they try to even suppress the whole topic. That to talk about them is some sort of derangement syndrome, lest people actually note how utterly insane, incompetent if not criminal their heroes are.

To be an Elon Musk apologists now betrays that someone is just a horrendous human being. Absolutely used toilet paper levels of humanity.

joseph_grobbles··on Facebook LLAMA is being openly distributed via torrents
(My posts are dead by default, but for the good showdead people if someone knows and can answer in a sibling reply)

Are models like this copyrightable? It seems like this falls under the realm of "fact", which can't be copyrighted.

joseph_grobbles··on Apple orders entire supply of TSMC's 3nm chips for iPhone 15 Pro and M3 Macs
It's called a stock swap, and Apple could easily accomplish it if from a financial perspective.

They could never achieve it with governments and regulators, however. Like 0.00% chance. Even if the government of Taiwan allowed it, there would be a long line of other governments and regulators blocking it.

joseph_grobbles··on We reduced our iOS app launch time by 60%
It's an engineering blog targeting other engineers. Some engineers discovered something that had a significant impact so they are communicating it to more engineers.
joseph_grobbles··on Virginia lawmakers pass marijuana legalization bills
That sounds like "street dealer" propaganda. There are a lot of actors whose income source is threatened who are parroting unsubstantiated claims about legal products.

It's a very simple plant to grow ideally. For a large industrial operation that is under no concern for law enforcement, run as a normal business, it's pretty easy and cheap to do things as optimally as possible.

joseph_grobbles··on "ERROR: could not open temporary file" after upgrade to Mac OS Big Sur
"Regardless, doesn't anybody at Apple use postgres?"

This problem occurs if you use anti-virus that delays file activities, and is 100% API consistent. Anyone saying "well it didn't do it before!" is being idiotic, similar to saying you don't need to check the return of malloc because it's usually going to succeed.

pgsql runs perfectly fine.
