It is also possible for a link-time optimizer to observe that a non-static global variable is never modified and optimize that away too.

But the Postgres mailing list is talking about 2000 global variables being a hurdle to multi-threading. I doubt they just didn't realize that most of them can be optimized into constants.

You just need a good EV. PHEV is like buying a typewriter with a screen when everyone is already buying computers. I have had a pure EV since 2019 and never had charging problems like that and I drive a lot. I have the 14-50 at home and it charges quickly, every morning I’m at 80% charge. Spend $100 to get an electrician to fix that for you.

1. You don't get funded. Actual investors are looking for could-be-very-profitable business plans, and founders who are especially likely to be able to turn those into reality. It does not sound like you know anything about farming, either in the "reliably make things grow" sense, or in the "costs vs. revenues" sense.
> How much of that actual cost is related to running a simple social blogging/connecting tool vs anything that is ad/surveillance/manipulation/etc?

It's plausible that the ad/surveillance/manipulation/etc makes up the bulk of development costs nowadays but I'd imagine the actual content (photos, videos, etc.) being served makes up the bulk of the costs. It undoubtedly could be made more efficient, but even if you could cut total operating costs by 99% (very unlikely) you still need $876 million/year. If you can only manage to cut it by 95%, you'll need over $4 billion/year. In any case, Reddit doesn't pay most of its moderators and it's still not profitable, so I don't think moderators make up a significant portion of the costs.

If you only want to share things with a small number of users, do you even need social media for this? Sounds like something a group chat on Signal or WhatsApp (with notifications silenced) would work for this if everyone you know is willing to use it. I like Facebook because it lets me see what my friends, family and former coworkers that I can't always see often are up to. Hard to stay in contact with everyone you've ever been friends with, but Facebook makes it a little easier.

I agree with you that Facebook is evil in many ways, and I'll 100% advocate for viable alternatives (which unfortunately I don't think distributed/federated networks are, due to regular users being confused by them), but I acknowledge that it's going to be very difficult to get people to switch. Ultimately I think there needs to be a reason to switch other than privacy (as most people don't care), and unfortunately Facebook can quickly copy any unique feature that an alternative network adds. It's not impossible for new platforms to come about, but most new platforms aren't really clones of old ones (TikTok isn't a clone of Facebook, YouTube or really any other major existing platform.) I don't know what the solution is. Not sure how much of an improvement it is for privacy, but in terms of mental wellbeing, I find Discord to be more enjoyable and less addictive, but again, it's not really the same thing as Facebook.
Existing social networks do a poor job though of actually allowing users to choose their own community. For Twitter specifically algorthmic timeline, replies, likes, and retweets will often put content from people you don't follow right infront of you. You can maintain your timeline more by unfollowing and blocking, but this is a bunch of effort you must do on a more individual level.

Mastodon's approach allows you to outsource a part of that by just joining an instance that doesn't even allow "alleged hate speech" into your timeline. That's the appeal of that.

But the point of federated Mastodon is not to have a platform that is solely moderated less than Twitter.

It's that:

- it's not twitter (or rather, it's a "twitter clone" that's non-commercial, not reliant on a single entity, has a degree of data portability built in - decentralised)

- it can allow for the spectrum of moderation styles to exist. The majority of bigger "mainstream" instances are probably going to opt to moderate similarly-ish to social networks, but this doesn't negate the other reasons for mastodon to exist. You can have instances that have an even stricter moderation standard, or even looser.

But at the end you don't need to get why one person prefers a network in one way, because federation means different ways can happily exist, and you chose what you prefer. Just don't be surprised if other people aren't enthusiastic about the people you hang out with.

To be fair, Tesla calls theirs "FSD" for essentially the same reason.
I have a one man SaaS that nets me $100k/yr in revenue. It's button-click simple to setup and requires zero maintenance aside from collecting the money each month.

The net assets are basically $15,000 worth of IT gear like a laptop and some servers. There is current month to month contracted revenue spread across a diverse base of users paying $5-100/mo each.

How much would you offer me for this company? How much would you take for this company if you currently owned it?

Something is worth what someone else is willing to pay for it. Obviously whatever the company sells for is worth exactly that amount at that moment in time. Valuing such a business at $15k would be absurd, just as valuing it at $15m would be.

Thus, the difference in asset value vs. what you paid is just called "goodwill" - perhaps the name hangs people up a lot.

If you then turn around and sell the same company later for a loss, you take a write down on that goodwill.

Certainly not perfect, but there aren't too many other ways you can express the present value of a company other than what it sells for.

TLDR: Basically, there's a CCS adapter hidden in the Supercharger stall. If you want to charge a CCS car, all you do is start the session from your phone. The CCS adapter unlocks, and it's on the end of the cable when you pull it out of the holder.

> Though it has Python bindings, OpenSlide is implemented in C and reads files using standard OS file handlers, however our data sits on cloud storage that is accessible via HTTP. This means that, to open a WSI file, one needs to first download the entire file to disk, and only then can they load it with OpenSlide. But then, what if we need to read tens of thousands of WSIs, a few gigabytes each? This can total more than what a single disk can contain. Besides, even if we mounted multiple disks, the cost and time it would take to transfer all this data on every new machine would be too much. In addition to that, most of the time only a fraction of the entire WSI is of interest, so downloading the entire data is inefficient. A solution is to read the bytes that we need when we need them directly from Blob Storage. fsspec is a Python package that allows us to define “abstract” filesystems, with a custom implementation to list, read and write files. One such implementation, adlfs, works for Azure Blob Storage.

AWS S3 has byte-range fetches specifically for this use case [1]. This is quite handy for data lakes and OLAP databases. Apparently, 8 MB and 16 MB are good sizes for typical workloads [2].

huge congrats to the Render team! especially raising a big round at a time when many VC insiders are saying things like the "series B and above market is closed".

I particularly remember the mad flurry by "cloud distro" startups to capitalize on Heroku essentially shutting down their free tier last year. It's an infrequent thing but I think having a playbook for how to respond when a major competitor churns up their own users on a silver platter is super helpful for future reference.

anything you'd call out as particularly helpful to you in the "post heroku wars" period? looking for specific principles i can extrapolate to other similar situations

Tucker Carlson's Interview With Elon Musk [video][1h 27M]
California's water apportionment is stupid as hell, and a perfect example of how 100 year old rules hamstring california in every way, and the "liberal" politicians there do not care to change it.

The way it works is that you have a set quantity of water rights, and even in a drought, your entire water right is fulfilled before the next person in line. This means that the farms on the bottom of the totem pole, which is ordered by seniority and 100 year old connections to grifters, not actual need or value or anything possibly meritocratic, gets whatever they can.

In fact, a huge publicized fight about water rights in california was only so the last group in line, a shitty farming company and group of companies in the literal desert, spent millions screaming about "We are letting all the water into the ocean to protect some dumb smelt" ended up with those smelt, which were the food source to lots of valuable fishing communities in the bay area, dying off and going completely extinct, and that farming community hasn't actually gotten anymore water because their original apportionment was not being fulfilled before, because it's a drought and they are last in line. This was a HUGE talking point all over fox news and it was stupid and meaningless.

I have a hybrid, basically get 30 miles on a charge. It’s frankly perfect!

To put it simply, there are two types of modes I drive - short & in town or long (100+ mile round trip).

There is absolutely zero chance I’ll be using an EV to drive over 100 miles as there’s a risk I get stuck for hours or even need a tow.

For in town trips, 20-30 miles is more than fine and I never even switch to gas. There’s very little trips in between.

Tesla holds a decent spot for suburban regions where you drive 10-120 miles round trip. Arguably that’s probably fine for half of America. Particularly, if you have two cars (one gas, one electric) as most households with EVs do.
Maybe only optimists can do it
If a mandatory reporter files a SAR, they are forbidden to share that info with customers. This doesn’t apply so much with payment processors. Stripe and others just don’t want to share their heuristics, because carders can thwart these heuristics. That’s more reasonable suspicion than some laws.
One likely reaction:

"Apparently everyone else is loved"
I think almost everyone understands that good intentions can lead to bad outcomes. But, also, everyone understands that good intentions can lead to good outcomes.

Determining which is which is a very hard problem. One strategy might be, "Don't do anything unless I'm absolutely certain it will lead to a good outcome." If you do that, you'll miss out on many opportunities that would have good outcomes but who's certainty isn't up to your standards.

So while the intention behind pointing out that good intentions can have bad outcomes is good, the outcome is bad.

So much this. I was ecstatic to hear the articles a few months ago saying that car manufacturers are going back to buttons. I prefer my car to have essentially no software. It needs to have a modestly sized screen and then whatever is necessary to display my navigation app and media app from my phone. Climate control and media control should both be physical buttons.

I recently bought an EV and a secondary concern (as in, not one of the primary concerns of size, range, charging speed, and price), was the control interface. I went with a model that has nearly all physical controls. Had the choice between otherwise equivalent vehicles been available, I'd have paid a non-trivial sum to get a button interface option.

From my Tesla-owning friends, I hear that their software is the "best", which seems to be like being the tallest dwarf. I literally can't imagine a pure software/touch interface being better than a physical button interface for the most important driving controls.
> Human and animal waste is compostable but only at industrial scale.

Not true! Plenty of people use composting toilets, for example people without plumbing (e.g. off grid houses) or homesteaders that embrace a re-use philosophy. You can do it at home - it's not that hard and it doesn't even smell if done right. Completely safe to use for trees and decorative plants if you keep it separate, but some people mix all their compost together and use it for everything. (If you want do the latter, you should probably read a little bit of compost literature first.)
> Level 2 chargers are not for spontaneous trips

What do you mean by this? Do you mean "public L2 chargers" or private in-home L2 chargers? If public, I agree--it would take 4 hours to charge your car on a road trip, but if private then just keep your car charged to 80-90%.

> My house was wired for level 2 charging by the previous owners but the plug is 220 3 prong rather than the NEMA 14-50 plug that seems to be de rigeur lately. At least I could probably get an electrician to fix that cheap.

There are multiple NEMA 3-prong 220V standards, at least one of which is 50V and at least Tesla sells charger adapters for all of them. If you're buying an EV though you may as well shell out the extra $500 + labor and have an electrician install the dedicated charger (so you can keep your portable charger in the car for traveling).

> If anything the non CCS chargers are made by idiots.

I'm not sure what this means either. The Tesla charger isn't CCS and I haven't had any problems with it. Also, plenty of CCS chargers suck (at least one of the CCS standards is exclusively L2).
> I think that says more about human therapists than it does about AI though.

“Just exercise, and get more sleep.”

Depressed people often deal with intrusive thoughts. The last thing you want is someone lying in bed, alone, while everyone else is asleep, entertaining those thoughts.

One of the archetypes of depression+sleep disturbance is people staying awake until they are absolutely exhausted and then collapsing into a sleep that the apocalypse could not rouse them from. That’s not a bad habit, it’s a coping mechanism.

I don't think you're gonna get one-size-fits-all answers the same way you will with avalanching hash functions. They can be one-size-fits-all because the requirement is that there is no (discernible) correlation between the input and output.

Locality-sensitive hashes depend on what sort of thing you are hashing. Is the data ordered, is it a sequence, is it points in space? The requirement is that given similarity in the input given a specific metric, there is a similarity in the output given another metric.

There are no universal locality sensitive hash functions because the function depends on in what sense you're trying to preserve locality.

All scripts are programs but not all programs are scripts.

A script is a program which includes its source and where the compile step (if it exists) is abstracted from the user, and where the source is distributed with the program.

Traditionally these are things which are run with a shebang first line, but that's not a strict requirement.

For example, if I distribute foo.java and can run it directly via "java foo.java" then foo.java is a script. (Java 11 added support for this.) If I have to run javac first and distribute only the resulting class, it's not a script.

That's my definition anyway.

one thing i really dislike is the disingenuous nature of calling NACS a standard because one wills it to be so.

it’s definitely more compact with thinner cables, and since CCS1 and CCS2 are different, it’s almost a half dozen of one situation.

I linked this in another subthread but I think it's worth reposting here because "penny wise" is an extreme disservice. "Blame someone else" by itself is unlikely to solve problems quickly, and there's time-proven alternatives too.

Also I don't want to know how much we'd have to spend to buy out even a quarter of the farms in the Central Valley.

https://www.khou.com/article/news/houston-will-be-drinking-d...

"We re handling right now about 135-140 million gallons [of raw sewage] per day, said Bill Tatum, manager of TRA Central Regional Wastewater System."

"This city needs almost a half billion gallons of water a day during the peak usage of the summer months, said Alvin Wright, spokesman for the City of Houston Public Works and Engineering Department."

That's a pretty big dent in the overall demand - though, amusingly, somewhat at risk because the cities in north Texas are going to start using more of their own sewage themselves.

Between things like this and capturing more storm runoff there's a ton for California cities to do to make them less dependent on other geographical areas and phenomenons beyond just "make people farm less." And especially if the climate patterns shift, closing the loop is just as important as getting rid of upstream consumers.

Water's a reusable resource, why are we still in the habit of polluting it and not cleaning up after ourselves?
