> To be clear, the problem is in how the power budget is being spent (most enterprise DCs don't even have 15 kW going to the rack).

I thought you were going for cloud DCs rather than enterprise. Seems like a big uphill battle to get software certified to run on your platform. Are any of the major Linux distros or Windows certified to run on your hypervisor platform? Any ISVs?

> The question on density is: how can you get the most compute elements into the space/power that you've got, and cramming towards highest possible density (i.e., 1U) actually decreases density because you spend so much of that power budget cranking fans and ramming air.

The question really is how much compute power, and electrical/thermal power ~= compute power. Sure you could fit more CPUs and run them at a lower frequency or duty cycle.

> And the challenge with OCP is: those systems aren't for sale (we tried to buy one!) and even if you got one, it has no software.

OCP is a set of standards. They certainly are systems sold. I guess the nature of the beast is that buyers of one probably don't get taken very seriously, particularly not a competitor.
A lot of big fortune 500s web appliance security stack will block a whole mess of newer TLDs to some degree... If you're targeting enterprise I'd recommend using .com
Passing array as a pointer is definitely a mistake. Not only is the size of the container lost, dimensionality of the array is lost as well. That a pointer to a pointer is syntactically the same as a pointer to a 2d array leads to a great deal of confusion in any codebase with a modicum of complexity.

But likely neither of these is as big as letting void * represent any arbitrary construct, be it pointer or data structure or the universe itself. Finding references to void * in a codebase is akin to crossing the event horizon of a black hole.
To add to this, sugar/sweets aren't the only thing bad for your teeth. Other less obvious things like bread or pasta are terrible for the teeth. Basically the "simple carbohydrates" group of foods.
Also acidity matters, try to keep it neutral like water/milk. (things like coffee or wine should be avoided).

Brushing times can also help and always floss at least daily.

If you're interested in learning more I would check out the teethtalkgirl YT channel. It's a great way to learn a heaps about teeth without paying $$$ at the dentist asking questions. (but you should still go to the dentist)

Anyway, that's my 2c, best of luck, teeth are the worst.

I've been building a little hobby-ish project recently to serve a gaming community I'm in (Splatoon) and I've been using fly.io for it. Being able to run it in multiple regions is useful for this in my opinion because the Splatoon community isn't just concentrated in one place, it's all over. If I hosted in the US then players from Japan would suffer and vice versa.

Even if this little project doesn't go anywhere, I still see it as a (probably) rather useful experience for someday when I'm like, out of school and stuff.

It's really neat to learn about I think. Right now I have it running in the Eastern US, Amsterdam, and Tokyo for about $10/month.
> I suspect that the independent internet died for pretty much the same reason why many people won't post anything interesting or authentic on social media anymore: Being active online can lead indirectly to real world harm to yourself or your family. Evil people use the internet to harass other people and to attack their livelihood or put the safety of their family at risk. Many employers now discriminate against employees or even just people applying for jobs who openly express opinions on the internet. And even posting pseudonymously isn't completely safe because it is usually possible to deanonymize posters if an attacker is obsessed enough.

ChatGPT’s response is pretty decent—

The paragraph you've provided is rich with technology details, which offer a good opportunity to delve into the history of computing. Here's a summary of the key technologies, people, and companies:

1. *NABU 1200:* This is a somewhat obscure early PC built around the Intel 8086 processor. The NABU Network was a Canadian computer network that existed from 1983-1985. NABU PCs were designed for home use and offered unique connectivity options for the time.

2. *8086 Unix machine:* Intel's 8086 was a 16-bit microprocessor designed in the late 1970s, which was the basis for the x86 architecture. UNIX, a powerful multi-user, multi-tasking operating system developed in the late 1960s and early 1970s at Bell Labs, was often used in early computers with this processor.

3. *Microsoft Xenix 1.0:* This was Microsoft's version of the Unix operating system, licensed from AT&T in the late 1970s and released in 1980. Xenix was a direct port of V7 Unix from Bell Labs. The "1.0" suggests this is the earliest version of Xenix.

4. *Bell Labs:* The historic research and development company responsible for a host of important technologies and programming languages, including Unix, the C programming language, and others.

5. *ST412 hard drive:* This was an early model of hard disk drive produced by Seagate Technology in the early 1980s. It was one of the first 5.25-inch hard drives and had a storage capacity of 10 megabytes.

6. *K&R C Compiler:* This refers to the original version of the C programming language as defined by Brian Kernighan and Dennis Ritchie (hence "K&R") in their classic book "The C Programming Language" (1st edition published in 1978). It predates the ANSI C standard.

7. *Elvis and vi:* Elvis is a vi clone, vi itself being a visual text editor for Unix. It was written by Bill Joy in 1976 at Berkeley. The reference to "compiling 'elvis' to get vi in the absolutely stripped down Minix mode" refers to the process of building the Elvis software from its source code to run on the Minix operating system, a Unix-like system designed for teaching purposes.

8. *Minix:* A Unix-like operating system created by Andrew S. Tanenbaum for educational purposes. The first version of Minix was released in 1987.

Overall, this paragraph presents a snapshot of a transitional time in computing, when PCs were still relatively new, Unix was becoming more common on these machines, and software had to be patched and compiled from source code to run on specific systems. The timeframe seems to be early to mid-1990s, considering the user bought the NABU 1200 at a garage sale around 1993.
> Big corporations with billions in profits without any real support staff….

No support staff is probably how they scaled up to billions in profits in the first place.
I think this along with what pfannkuchen suggested both may contribute to this unexpected result. In addition, instant coffee tends to be made from much lower quality beans; lower quality beans tend to be used in darker roasts and seem like they would have higher acrylamide content. In addition, the additional heating step the instant coffee goes through might also further elevate acrylamide.

https://www.cancer.gov/about-cancer/causes-prevention/risk/d...

I think it would be useful to test and compare amount of acrylamide in instant coffee versus the typical medium roast coffees, in addition to seeing whether this substance affects telomeres.
"Confession" is fine as a translation. 告白 can be used for admitting to crimes, confessing one's love, revealing a secret, etc. It would never be used for a declaration where there is no sense of guilt/shame/embarrassment involved.

can you elaborate on your setup a bit more?

I've been struggling to find a way to do this. Seems like everything I find has removed any FTP/SFTP support and wants to send pics over LTE to an email address.

My goal is a simple weather cam that will upload an image every 1 minute. Simple as that. Old 2000s webcam style. I ran into an unsolved problem with my rPi3 and a Logitech cam and mostly gave up out of frustration.
On an unrelated note, should I be concerned if a British style police box seems to have appeared in a random location in my town?

...and it's red?

...and there is a line of tiny skulls on stakes near it?

...and until I checked Google Street View I could swear it was blue when I drove past?
It’s called fluoride varnish. The ADA use to recommend it only for children but in the last decade they updated their guidelines to include all ages. My dentist applies it now but my insurance does not cover it.
I got a strong trypophobia shiver from seeing that skull image. (I know it's an objective medical affinity)
>some $6.7 trillion was spent on alt-energy globally between 2004 and 2022, with the vast majority of that, some $4.8 trillion spent on renewables. And the vast majority of that $4.8 trillion — about $4.1 trillion — was spent on wind and solar.

This is an interesting stat, but I think it's misleading - the vast majority of cost for solar/wind is upfront, so it will naturally appear more expensive in the short term even if it's cheaper overall. Also, obviously, there was far more invested into solar in 2019 than there was in 2006.

I agree that the energy transition isn't (and obviously the Biden administration wants to pretend otherwise, because "we're solving climate change" is just great politics), but I want to attack some of the implicit assumptions why:

First up, the problem isn't renewables being too expensive, it's that they're too cheap and competitive. If you expect the price of future goods in a market to drop like a rock, why on earth would you want to enter that market, let alone commit significant investment into today's goods? Companies care about being profitable, not about being cheap. And as a quick aside, of course more is invested into the tech that currently holds 90% of the market.

Second up, reliability doesn't matter yet - if your electricity sources are 50% gas and 50% renewables, then you're just fine. Yes, when we get to the finish line this will be a big problem, but our deadline is not dictated by time, but by emissions. If we emit 100N emissions per year today and we reduce that down to 10N next year, then we have 10x longer before man-made emissions push us past whatever our goal is. As such, focusing on the last 10% is a terrible idea if it even slightly hinders our adoption for even the first 50%.

Third up, energy vs electricity is a double-bind. For example, switching to renewables alone won't stop ICE car emissions, but a very common criticism of electric cars is "why bother, the electricity is just coming from coal anyway". These two criticisms demand mutually exclusive sets of priorities, and if you pick one then people will hit you with the other.

The energy transition isn't, but we desperately need to discuss why instead of making assumptions.
This is patently false.

God. Migrate to Salesforce was exactly the idea brought up by the sales side at a job of mine. I was on the IT side. Thank god we talked them down (plus they got sticker shock).

Some sales asks were legit and we got 'em done. Some were legit but low ROI and never done/priority even as sales had majority say in those priorities. Some were "please take this customer-hostile, flaky, human-explicitly-in-the-loop CRM workflow that has the thinnest veneer of plausibility above pure gaming of KPIs and insert it into a core product flow that's working well".

I think low code tools will continue to proliferate and I'm not against it. I do think they will be an interesting test of how much and in what contexts consumers are willing to accept half baked solutions. The capital environment this past decade has meant corporate leadership has been able to touch hot stoves without getting burned. Often they've been rewarded for it.

The thread is about where the oxide niche is and what advantages it has over competition. The idea there is huge amount to be won on southbridge chipset and IO ports in large scale systems is simply not true. Quite amazing that people who don't understand this are posting in this thread as though they are experts in the matter.

Dental insurance is usually pretty decent in the US, probably not worth leaving the country unless it's significant work. I have no idea with OP is getting done that costs thousands of dollars. Certainly that's an outlier.
Allot of it is also education. I grew up thinking, if you get a cavity the dentist will fix it, no worries. But you're teeth can only be repaired so much, and every time it's more expensive.

I never asked any questions or tried to understand why I got cavities (in part cos of the cost). It was just... I have bad teeth, it is what it is. But it's not. there is allot you can do, foods to avoid, drinks to avoid (beyond the obvious).
But things are getting better, some dental hygienists are on YouTube now, who teach how to look after your teeth.
Cool we can regrow teeth, but hair regrowth is fucking impossible because God hates me.
well heck. yes, sivers@ founded CD Baby, not Bandcamp.
Most people say linux, but mean GNU+Linux. Clearly, being a world-renowned software dev, and being in-your-face pedantic for literal decades isn't enough to get the point across for some people. Add whichever tooling you want (I've heard KDE+Linux before, and without looking it up, suspect Gnome+Linux wouldn't be wrong), but don't pretend Android doesn't use the Linux kernel.

I'll take my downvotes here for being an ass, but on a forum that loves being pedantic, I legitimately expect better. Android is Linux. Typically with an outdated kernel, without root, with a locked bootloader, and without the GNU tooling, but it's pretty hard to argue Android's not Linux.
How do you fit all the codebase tho? GPT-4 is limited to 32k tokens which is like 500 lines?
I noticed the exact same thing and the fact it didn't pick up my login session in safari... which for me raised some alarm bells that this "could" be a nice ploy to grab my google credentials.

For this reason it was a hard no, I proceeded no further and deleted the app.
> this sounds like a joke… “with no bathtubs”

Maybe from an American POV.
This is an article by NHK by a Japanese reporter and likely a spin of a similar story for a Japanese audience. In Japanese culture, being able to bath is up there with being able to eat.
Wisdom teeth aren't the problem, they're supposed to be there. Wisdom teeth getting compacted are a symptom of a larger problem.

If a child is not fed enough tough foods, then they end up not using and developing their facial muscles correctly.

If those muscles which should be guiding the jaw into it's correct position aren't being used correctly, they end up causing the jaw to not develop properly. Now you end up with a mouth-breathing child who has a reverse swallow, crowded teeth, and is going to need braces, a retainer, and possibly a CPAP machine.
If this is all at one dentist, you may want to get a second opinion. It is very rare, but some dentists do more work than is necessary.
Should have closed the door and said don't open until 2030!
Is the article not about subtle differences around love in Japan?
> The page says "updates," not "writes." Updates are a constrained form of write where you are writing to an existing key. Updates, importantly, do not affect your index structure, while writes do.

OK, I see your point. It would only have made things even worse for LevelDB here to do an Add/Delete workload because its garbage compaction passes would have had to do a lot more work.

> It is normal for a small B+tree relative to the memory size available on the machine. The "small" was the unrepresentative part of the benchmark, not the "B+tree."

This was 100 million records, and a 5-level deep tree. To get to 6 levels deep it would be about 10 billion records. Most of the branch pages would still fit in RAM; most queries would require at most 1 more I/O than the 5-level case. The cost is still better than any other approach.

This could be done by storing the length of the array before the first element. It wouldn’t even need to be done in all cases, only if the length is actually used.
Honestly a self-hostable HN clone, so no rings/communities/subreddits or anything, I think could be kind of cool. 1 community per server, so they stay naturally pretty small. If you find a post out in the wild, the domain name tells you exactly what the general topic is.

You could use activity pub to handle a “personal front page” that includes stuff from other instances per user.

I recently spoke with a friend who is not in the tech space and he hadn’t even heard of ChatGPT. He’s a millennial & a white collar worker and smart.
