Talur from 7x16 Thine Own Self

Names blurred to protect the innocent / crazy. Not trying to call anyone out, just thought the response was hilarious and highly disproportionate. Like, they distinguished that comment (green border/background).

For reference, the comment I presume that was downvoted that apparently triggered that response was to the tune of "BoTH SiDEz!!!!" with some hyper generalizing / stereotyping on the side.

With modern tools, you have to try very hard to do something stupid, because the tools (rightly) recognize you’re doing something stupid. [Andreas Karlsson] can speak to that first hand as he tried to get four billion if statements to compile.

You may ask what state space requires four billion comparisons to evaluate? The answer is easy: the range of an unsigned 32-bit integer. The whole endeavor started with a simple idea: what if instead of evaluating whether an integer is even or odd with a modulo or bit mask, you just did an if statement for every case? Small ranges like 0-10 are trivial to write out by hand, but you reach for more automated solutions as you pass 8 bits and move towards 16. [Andreas] wrote some Python that outputs a valid C program with all the comparisons. For 16 bits, the source only clocks in at 130k lines with the executable less than 2 MB.

Of course, scaling to 32 bits is a very different problem. The source file balloons to 330 GB, and most compilers barf at that point. Undeterred, [Andreas] modified the Python to output x86_64 assembly instead of C. Of course, the executable format of Windows (PE) only allows executables up to 4 GB, so a helper program mapped the 40 GB generated executable and jumped into it.

What’s incredible about this whole journey is how performant the program is. Even large numbers complete in a few seconds. Considering that it has to thrash 40 GB of an executable through memory, we can’t help but shake our heads at how even terrible solutions can work.

New Features

Link Previews

Under Settings -> General is a new option called "Preview Links in Modal". This is enabled by default but can be disabled. It is also under the quick options.

Clicking markdown links (in post body, comments, sidebars, etc) will do a server-side metadata fetch and render a preview. "Internal" links that load in Tesseract will not preview and simply use the user's "open links in new tab" preference.

The preview includes:

• Link metadata if available (thumbnail image, embed video, description, title)
• Alternate source selector
• MBFC report (if available)
• If link is to a supported media type (YT, Invidious, Piped, Soundcloud, Bandcamp, Spotify, Odysee, PeerTube, etc), will show the media as an embed
• If metadata description contains links, they will preview in the same modal, and a "back" button will be enabled to return you to the previous preview.

e.g. If someone drops a bare Youtube link, it will render in the modal using your preferred YouTube frontend. Same for a Spotify, Bandcamp, etc link. The link is processed through the same rendering chain as posts, so any supported media should render as if it were posted to the feed.

It also has the alternate source selector and the MBFC plugin tied in, so a news article link in the comments can be vetted for credibility, previewed, and followed.

Post links are not tied into this since the post itself acts as the preview / renderer. This can be implemented, and easily, but it seems pointless to me. If I get feedback saying it should handle the main posts links through that, then I can enable it or at least make an option to.

Image Descriptions: The post image demonstrates the preview modal that's loaded when clicking the raw Youtube link in the comment shown above. The second image shows the preview for a news link posted in the comments of another post.

Badge-ified Community and User Links and Hashtags

Community and user links in post and comment bodies are now badge-ified and load the community or profile modals upon click (versus the old behavior of being a dumb link to the profile/community pages).

Currently, user links are blue, and community links are orange.

Hashtags are now converted into badges/flairs and are yellow.

A CNN reporter spent more than two hours waiting for EV chargers — thanks to "ill-mannered charger hogs who don't respect EV etiquette."

[T]o protect batteries from damage, charging speeds slow way down once batteries get beyond 80% full. In fact, it can take as long, or even longer, to go from 80% charged to completely full than to reach 80%. Meanwhile, lines of electric vehicles wait behind almost-full cars. I was waiting behind people with batteries that were 92%, 94% and even 97% full, as I could see on the charger screens. Still, they stayed there. I made my own situation worse by giving up on one location and going to another with more chargers, but there were even more EVs waiting there.

Given that a lack of public charging is turning many consumers off to EVs, according to multiple surveys, this is a major issue. Both Electrify America and EVgo said they are rapidly expanding their networks to, as EVgo's Rafalson put it, "skate ahead of the puck," trying to make sure there are enough chargers to meet future demand... "I think what you're seeing is demand for public fast charging is really skyrocketing," said Sara Rafalson, executive vice president for policy at EV charging company EVgo, "and I would say we've been really at an inflection point in the last year, year and a half, with demand...."

Electrify America, one of America's biggest charging companies, is experimenting with a solution to the problem of charger hogs who can make it slow and unpleasant to travel in an EV. At 10 of the busiest EV fast charging stations in California, Electrify America has enacted a strict limit. Once a car's batteries are 85% charged, charging will automatically stop and the driver will be told to unplug and leave or face additional 40-cent-per-minute "idle time" fees for taking the space. It's similar to something Tesla vehicles do automatically. When a Tesla car, truck or SUV plugs into a particularly heavily-used Supercharger station, the vehicle itself may automatically limit charging to just 80% "to reduce congestion," according to Tesla's on-line Supercharger Support web page.

In that case, though, the user can still override the limit using the vehicle's touchscreen. There will be no getting around Electrify America's limit.

Electrify America's president points out an EV driver could need a full charge (if they're travelling somewhere with fewer charges) — or if they're driving an EV with a relatively short range. So the article notse that some EV charging companies "have experimented with plans that charge different amounts of money at different times to give drivers incentives to fill their batteries at less busy hours...

"For the time being, let's just hope that EV drivers who don't really need to fill all the way up will learn to be more considerate."

I don't know if it's the platforms, the users, or both, but it just annoys the ever loving crap out of me that cloud storage is basically used like a digital junk drawer.

There's this article about how Gen-Z doesn't apparently understand how filesystems work which kind-of, maybe, explains things a bit. Again, I blame tech for that.

Even with search, I can't find half or more of the files co-workers swear are in there.

And I know they know how to put things into folders. We were using an on-prem fileserver until 4 years ago, and they filed things just fine. Now files just go into a "bucket" and they expect you to rummage through it to find what you need.

So I tied a Tamagotchi to my belt, which was the style at the time

Note: The community is about a year old. It was originally going to be a personal blog, but I never found the time to write-up my tech hate, so it kind of languished. So now I'm re-branding it as a place for anyone to dump hate for current tech trends (in any format) since I didn't see any other community for that purpose (that wasn't for a specific trend - e.g. AI).

Ooh, look at my shiny, new uPhone 24. It's so thin, you guys! (proceeds to put it into a bulky-ass case)

6x19: Lessons

It also doesn't hurt that it's basically a sequel to The Inner Light.

New preliminary evidence for phosphine and ammonia in Venus's atmosphere deepens the mystery of their origins, suggesting the possibility of a biological source. The detections, made using the James Clerk Maxwell Telescope and the Green Bank Telescope, point to potential microbial life in Venus's clouds despite the planet's extreme surface conditions. Space.com reports:

The new detections of phosphine and ammonia were obtained by a team led by Jane Greaves of the University of Cardiff using submillimeter radio wavelength data collected by the James Clerk Maxwell Telescope (JCMT) in Hawaii and the Green Bank Telescope in West Virginia. "We don't know how you make phosphine or ammonia in an oxygenating atmosphere like that of Venus," said team member and astrophysicist Dave Clements of Imperial College, London, in an interview with Space.com. Then again, it's not clear why biology on Earth produces phosphine, either." Whether it's in penguin poop or badger guts, we don't know why bacteria make phosphine, but they do."

The JCMT's initial detection of phosphine on Venus in 2020 by Greaves and her team was met by fierce disagreement from some quarters. This disagreement focused on how the data was processed and whether that was creating spurious signals since observations by other telescopes struggled to detect the phosphine. Clements said those technical disagreements have now been resolved and that the latest measurements, using a new detector on the JCMT called Namakanui (meaning 'Big Eyes' in Hawaiian), have come from three observing campaigns, each providing 140 times as much data as the initial detection. [...]

Clements is open to the possibility that both phosphine and ammonia are being produced by some rare photochemistry in Venus' upper atmosphere involving solar ultraviolet breaking up molecules and allowing phosphine and ammonia to form from the molecular debris. If that is the case, nobody has observed this process yet, not even in the laboratory. Another possibility that has been mooted is that the phosphine could be produced by Venusian volcanoes. Clements also pointed out that the European Space Agency's Jupiter Icy Moons Explorer (JUICE) is making a fly-by of Venus in August 2025 to help slingshot it towards the Jovian system. JUICE carries instruments capable of detecting phosphine and ammonia, but there's no guarantee that its instruments will be switched on and deployed at Venus.

"Generation X and millennials are at an increased risk of developing certain cancers compared with older generations," reports the Washington Post, "a shift that is probably due to generational changes in diet, lifestyle and environmental exposures, a large new study suggests."

Researchers from the American Cancer analyzed data from more than 23.5 million patients who had been diagnosed with 34 types of cancer from 2000 to 2019 — and also studied mortality data that included 7 million deaths in the U.S. from 25 types of cancer among people ages 25 to 84. [The researchers reported] that cancer rates for 17 of the 34 most common cancers are increasing in progressively younger generations. The findings included:

• Cancers with the most significant increased risk are kidney, pancreatic and small intestine, which are two to three times as high for millennial men and women as baby boomers.
• Millennial women also are at higher risk of liver and bile duct cancers compared with baby boomers.
• Although the risk of getting cancer is rising, for most cancers, the risk of dying of the disease stabilized or declined among younger people. But mortality rates increased for gallbladder, colorectal, testicular and uterine cancers, as well as for liver cancer among younger women.

"It is a concern," said Ahmedin Jemal, senior vice president of the American Cancer Society's surveillance and health equity science department, who was the senior author of the study. If the current trend continues, the increased cancer and mortality rates among younger people may "halt or even reverse the progress that we have made in reducing cancer mortality over the past several decades," he added.

While there is no clear explanation for the increased cancer rates among younger people, the researchers suggest that there may be several contributing factors, including rising obesity rates; altered microbiomes from unhealthy diets high in saturated fats, red meat and ultra-processed foods or antibiotic use; poor sleep; sedentary lifestyles; and environmental factors, including exposure to pollutants and carcinogenic chemicals.
