• Some of the Hololive EN streamers have an expression: One guyed.
  
  It's when they're playing a game or trying to solve a technical issue and ask chat for help, and get a prompt and authoritative answer from one guy among the thousands watching that turns out to be completely wrong.
  
  ChatGPT is that one guy.  (The Register)
  
  Taking a look at ChatGPT answers to Stack Overflow questions - a devil's brew of epistemic closure if I ever saw one - researchers found that ChatGPT had no better than a 50% chance of being correct, and for the best and most authoritative answers - the ones that were accepted by the questioner as definitive - ChatGPT was wrong 77% of the time.
  
  I've said before that the entire model of ChatGPT is building an artificial arts student, but really it seems to be building an artificial confidence trickster.

• Intel's 14700K has been benchmarked, and is between 5% and 20% faster than the 13700K.  (Tom's Hardware)
  
  5% on single-threaded tasks thanks to a 200MHz speed boost; 20% on multi-threaded tasks thanks to four additional Efficiency cores.
  
  Nothing groundshaking but if they keep the same price it will be a worthwhile improvement.
  
  Big changes may be coming at the entry level, with the 14100 rumoured to have six Performance cores, up from four.  If true, and if the price again remains the same, that will be a great little chip.
  
  
  
• Meanwhile on the great big chip front AMD is preparing to release Epyc Siena for low-end servers and Threadripper 7000 Pro for high-end workstations.  (Tom's Hardware)
  
  Siena will support up to 64 cores at a 200W TDP, while the new Threadrippers will offer up to 96 cores at a 350W TDP.
  
  The two families of chips will share the same SP6 socket, which is the same physical size but a different pin layout as the previous generation of Epyc CPUs.
  
  
  
• SK Hynix has launched 24GB LPDDR5X-8500 memory...  Things.  (AnandTech)
  
  They're not modules in the sense of DIMMs, but each one contains 8 memory chips in a stack, so they're not chips either.
  
  Anyway, since they're 64 bits wide a laptop would need two of them, giving 48GB of RAM, which is enough even for me.
  
  
  
• Mediatek's Dimensity 9300 meanwhile supports LPDDR5T-9600 memory, which is one louder.  (WCCFTech)
  
  And has four Cortex X4 cores and four A720 cores - four fast cores and four ultra-fast cores - with no slow cores at all.
  
  Sounds like a good chip for a laptop, actually.  Most phone chips only have one of the Cortex X series cores, which is fine for phone use but not so great in more demanding applications.
  
  
  
• LPython is a Python compiler...  Ish.  (LPython)
  
  It seems to be designed primarily for type-annotated Python code, though it can run unannotated code as well, compiling it into C and thence to native code, rather like Cython.
  
  But it can also JIT-compile live code, rather like PyPy - or given that it uses decorators to do this, like PyPy's predecessor Psyco.
  
  And unlike Mojo, you can actually download it and try it out right now.
  
  
  
• A look inside the Linux kernel.  (Seiya)
  
  The Linux kernel as of version 6.5 is 36 million lines long, too much for any one human to comprehend.  So this article doesn't try; it instead looks at Linux 0.01, the first public version, which is only 10,000 lines.

• Sam Bankman-Fried, disgraced head of failed crypto Ponzi scheme FTX, has had his $250 million bail revoked and been sent to jail to await trial, under new charges of witness tampering.  (CNBC)
  
  Because he spoke to the press.
  
  Bankman-Fried is a fool and a phony and I'm almost starting to believe he's innocent of the specific charges.  Not that I would ever let him within a dozen firewalls of my digital funds.

• Google wants content scraping by AI tools to be considered fair use.  (Tom's Hardware)
  
  Of course they do.
  
  But...  Why shouldn't it be?
  
  I can read whatever I like on the internet, and express my opinions here.  Well, not if Prime Minister Albonazi manages to shove his godforsaken misinformation bill through Parliament but until then we have the tacit assumption of freedom of speech down here, even if it is not specifically protected under our Constitution because nothing else is either.
  
  And not that those specific protections are worth much in the US anymore.
  
  Anyway.
  
  Why shouldn't training AIs on public material be fair use under the First Amendment?  How can we have free speech if we don't have free listening?
  
  
  
• Disabling the Efficiency cores on Intel CPUs nets a 50% performance boost on new game Atlas Fallen.  (WCCFTech)
  
  Which is apparently not an unauthorised sequel to Shrugged.
  
  I'm not sure who exactly screwed this up, but the article points the finger at the game developer and not Microsoft.
  
  
  
• Use text-to-speech to instantly create your own podcast.  (Hacker News)
  
  No.
  
  
  
• The You Can't Just Say That S25-0801 offers eight 2.5Gb ports and one 10Gb port, but the 10Gb port is SFP so it goes straight onto the trash pile.  (Serve the Home)
  
  Around $100.  Shame about, uh, that.

  The bottom of the switch has two mounting points. It also has a You Can't Just Say That product label. We will just quickly note that the "You Can't Just Say That" name was one of the most frequent points that commenters focused on in the YouTube video.

  You don't say.
  
  Probably because you can't.
  
  
  
• Austria's telecommunications regulator has ruled that courts can order DNS blocks for various nefarious activities, but cannot require ISPs to block IP addresses.  (TorrentFreak)
  
  Which is a sport our own authorities in Australia are a little too keen on as well.
  
  The problem in this case is that a single IP address can host, say, 96,530 individual websites.

• LK-99 might not be a superconductor at all - let alone at room temperature - which is odd because one of the things that has been confirmed is that it works as a superconductor at least at liquid nitrogen temperatures.  (Tom's Hardware)
  
  What's going on?  It looks like the pure material may not be a superconductor, and its behaviour is very dependent on impurities.  Which lines up with recent theoretical analyses.
  
  The original lab in Korea is now providing samples of their own material to independent researchers, so the story is likely to resolve itself one way or another in the next couple of weeks.

• The Doogee T20mini is an 8.4" Android tablet with a 1920x1200 screen, an adequate CPU (two A75 cores and six A55 cores, all at 1.6GHz), 4GB of RAM, 128GB of storage, a microSD slot, and a headphone jack, running on Android 13.  (Notebook Check)
  
  List price is $265 but it's available for pre-order at $135, shipping next week.

  Well, fuck.
  
  Do not want.
  
  
  
• Twitter is close to break even.  (Tech Crunch)
  
  Before Elon Musk bought the company, it was losing $4 million per day on average.
  
  After he took over, advertisers fled fearing a backlash from leftist lunatics who don't buy their products anyway, and despite massive cost savings from firing its own horde of leftist lunatics, the company was still losing money.
  
  Tech Crunch is skeptical about all this when they post every press release in existence verbatim, because, well, they are also leftist lunatics.
  
  
  
• Samsung has announced 256TB SSDs.  (Tom's Hardware)
  
  Not much information about the exact specs, because (a) Samsung doesn't seem to have said and (b) none of the images in the article will load because the SSL certificate for the CDN has expired.

• Seattle looks set to be the first city in the US to protect gig workers from being arbitrarily revoked.  (KUOW)
  
  Companies like Uber have a bad habit - well, they have lots of bad habits, but they have a particular bad habit of treating their workers like accounts on social networks: You get up in the morning and your job is gone.
  
  No warning, no explanation, no recourse, it's just not there anymore.
  
  I haven't read the legislation and I don't expect Seattle to get it right - though it's worth noting that two council members voted against it because they thought it was overbroad - but if you behave unreasonably for long enough, someone, somewhere, is going to hit you with a rock.

• Silicon Motion is preparing a PCIe 5 SSD controller with a power consumption of 3.5W.  (AnandTech)
  
  That's about one third of current PCIe 5 controllers and in line with existing PCIe 4 models.  If they can also cut the price drastically, PCIe 5 SSDs might actually have a reason to exist.

  The very first multi-layer flash chips were introduced 10 years ago this week with 24 layers.  At the time the flash memory industry was approaching a crisis because flash cells couldn't be made smaller without becoming so unreliable as to be basically useless.

• After raising $22 billion in funding and soaring to a peak valuation of $47 billion, WeWork now boasts a market cap of $166 million.  (Tech Crunch)
  
  That's a 99.7% decline, but still better than I thought because I was under the impression that they went bankrupt last year. 
  
  So how's it going?

  Today, the 13-year-old company announced a net loss of $397 million for the second quarter on revenue of $877 million.

  That good huh?

  As such, WeWork went on to say its ability to continue operating is contingent upon "successful execution of management’s plan to improve liquidity and profitability over the next 12 months."

  It's worse than that, he's dead, Jim.

• Lyft wants to kill surge pricing.  (Tech Crunch)

  "[Primetime pricing] is a bad form of price raising," said Risher.  "It’s particularly bad because riders hate it with a fiery passion. And so we’re really trying to get rid of it, and because we’ve got such a good driver supply ... it’s decreased significantly."

  Getting rid of something because all your customers hate it.  Imagine if Apple or Microsoft heard of this.

• Zoom has announced that su casa es mi casa.  (Stack Diary)

  What raises alarm is the explicit mention of the company's right to use this data for machine learning and artificial intelligence, including training and tuning of algorithms and models. This effectively allows Zoom to train its AI on customer content without providing an opt-out option, a decision that is likely to spark significant debate about user privacy and consent.

  Zoom has always been run by scumbags.  It's a miracle they haven't been sued out of existence by now.

  Additionally, under section 10.4 of the updated terms, Zoom has secured a "perpetual, worldwide, non-exclusive, royalty-free, sublicensable, and transferable license" to redistribute, publish, access, use, store, transmit, review, disclose, preserve, extract, modify, reproduce, share, use, display, copy, distribute, translate, transcribe, create derivative works, and process Customer Content.

  This kind of language is normal, but usually specifies that this is to be done solely to provide the service to the customer, not just for whatever the company wants.
  
  This predictably blew up on Hacker News, eliciting this response from Zoom:

  Hi there - this is Aparna from Zoom, our Chief Operating Officer. Thank you for your care and concern for our customers - we are grateful for the opportunity to double click on how we treat customer content.

  Double click?

  To clarify, Zoom customers decide whether to enable generative AI features (recently launched on a free trial basis) and separately whether to share customer content with Zoom for product improvement purposes.

  There may be a button to do so in the application.
  
  The problem is with your terms of service, in which you grant yourself license to do whatever the fuck you want, buttons be damned.

• One of the videos purportedly showing magnetic levitation of much-hyped potential room-temperature superconductor LK-99 has been retracted and taken down.  (Tom's Hardware)
  
  Though it's worth noting that of the videos produced so far, this is the one that immediately denounced as being as fake as a three-dollar Confederate bill:
  
  
  
  
  
  
• Kioxia (Toshiba) has announced a new range of PCIe 5 SSDs with transfer rates up to 12GB per second and capacities up to 30TB, in a traditional 2.5" size or the new E3.S form which looks like a roided-up M.2.  (AnandTech)
  
  Compact SSDs are now readily available in capacities exceeding any hard drive.  They're still significantly more expensive, but that's fallen from a factor of 10 to a factor of 2 in a remarkably short time.  And they are much, much, much faster.
  
  
  
• The Galaxy Tab A9 could be the replacement form the current A7 Lite.  (Liliputing)
  
  I have the A7 Lite.  It's an adequate small tablet except for the screen, which is trash.  If the A9 is a small tablet - in the 8" range - and has a 1920x1200 or better screen, I will buy three of them.
  
  
  
• Need a passively-cooled eight core four port 2.5Gb Ethernet router/firewall device with up to 32TB of storage?  Here's on.  (Serve the Home)
  
  Not terrible either, by the look of things.

• Yes, we can regulate online toxicity.  (PC Magazine)
  
  Now I'll grant you that this article mostly focuses on the platforms' recommendation algorithms and not the users' content, so it's far less a Journalists for Censorship piece than most.
  
  But attempting to regulate complex software systems that are poorly understood even by their own developers and are only fourth-order-tangentially related to any of the ascribed harm is likely just to make things worse.
  
  Instead mandate transparency.  Got a magical new recommendation algorithm that gives you an edge over your competitors?  Too bad, so sad, you have to publish that code.
  
  Or just stop using recommendation algorithms and hand control back to the users themselves.

• It's a real tech news wasteland today.
  
  
  
• SpaceX launched yet another 22 satellites and landed the rocket flawlessly on the recovery ship.  (Space)
  
  Ho hum.
  
  
  
• The company also carried out a static test fire of Booster 9, a new Super Heavy booster for Starship, made up of 33 Falcon 2 rockets.  (Space)
  
  It didn't explode.  So dull.
  
  
  
• The ninth Dedekind Number has been discovered.  (Quanta)
  
  It was in Madagascar, hiding under a log.

  Another way of thinking of the Dedekind number is in set-theoretic terms. Think of a set with n elements, say the numbers {1, 2, 3, 4, 5, …n}. That set has 2n different subsets, which form a mathematical structure called a lattice. Now collect those subsets according to the following rule: No subset in your collection can be a part of another subset in the collection. Such a collection is called an anti-chain, because it combines points on the lattice in a way that doesn’t form a chain. (For example, {{1}, {2, 3}, {3, 4, 5}} forms an anti-chain.) The number of anti-chains for a given n is, again, the Dedekind number.

  I'm not sure exactly why I would want that, but I at least understood it.
  
  
  
• Don't buy Chromebooks.  (Ars Technica)
  
  Chromebooks generally have fixed lifespans after which they stop receiving updates, because Google is a garbage company in a garbage industry.
  
  Amazon and Walmart are selling Chromebooks that have already expired, at full price, because garbage companies in garbage industries.
  
  And they do not make any note of the fact that they are selling the digital equivalent of rancid meat, anywhere.
  
  Unsurprisingly, none of the companies involved have responded to questions.

• There's nothing quite like getting woken up at 3AM because the websites your company runs are in the middle of a firehose vulnerability scan from the latest botnet.
  
  Every single attempt was failing because we don't run any of the crap they were trying to break into (or at least, not on the public internet) but the volume was so high it tied up every single thread on all the back-end servers.
  
  
  
• A second group has now replicate room-temperature magnetic levitation in LK-99.  (Tom's Hardware)
  
  While another group reports that the material is really fussy to work with.
  
  It may be a room-temperature superconductor if you win the synthesis lottery.  It is pretty consistently a normal high-temperature superconductor, but "high temperature" there means liquid nitrogen rather than liquid helium.
  
  Also so many researchers are playing with this stuff that the raw materials aren't available from regular suppliers right now.  Out of stock globally.  None of it is rare, it's just not made in bulk because nobody wanted it much.
